3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Application Processor (AP): part of mobile device hardware working under OS control and on which User
Applications, among others, are executed
Baseband Parameter Aggregation (BPA): unit collecting all the context information to be transferred to the monitor
NOTE: The BPA unit converts the context information into metric(s) such that a minimum bandwidth is
consumed during the procedure of transferring the context information to the monitor. Those metrics may
include Received Signal Strength Indication (RSSI) measurement, multi-RAT performance metrics, etc.
communication services layer: layer related to communication services supporting generic applications
NOTE: A communication services layer supports generic applications like Internet access. In the present
document, it consists of Administrator, Mobility Policy Manager (MPM), Networking stack and Monitor.
configcodes: result of compiling the source codes of a Radio Application (RA), which is either configuration codes of
Radio Virtual Machine (RVM) or executable codes for a particular target platform
NOTE: In the case when RA provider makes a high level code based on a target platform, a result of compiling
RA source codes is configcodes which is executable on the target platform. In the other case, when RA
provider makes a high level code without considering a target platform, a result of front-end compiling of
RA source codes is an Intermediate Representation (IR) which should be back-end compiled for operating
on a specific target platform.
data flow: logical channel between Flow Controller (FC) and a Unified Radio Applications (URA) created by FC to
send to or receive data elements (octets, packets or other granularity) from URA
environmental information: set of values that can affect the execution of RAs on a Radio Computer
NOTE: Environmental information consists of information related to the execution of RA(s), such as Buffer
Overflow, Resource Allocation, etc.
Functional Block (FB): function needed for real-time implementation of RA(s)
NOTE 1: A functional block includes not only the modem functions in Layer1 (L1), Layer2 (L2), and Layer 3 (L3)
but also all the control functions that should be processed in real-time for implementing given RA(s).
NOTE 2: Functional blocks are categorized into Standard Functional Blocks (SFBs) and User Defined Functional
Blocks (UDFBs). In more details:
1) SFB can be shared by many RAs. For example, Forward Error Correction (FEC), Fast Fourier
Transform (FFT)/Inverse Fast Fourier Transform (IFFT), (de)interleaver, Turbo coding, Viterbi
coding, Multiple Input Multiple Output (MIMO), Beamforming, etc. are the typical category of
standard functional block.
2) UDFB include those functional blocks that are dependent upon a specific RA. They are used to
support special function(s) required in a specific RA or to support a special algorithm used for
performance improvement. In addition, a user defined functional block can be used as a baseband
controller functional block which controls the functional blocks operating in baseband processor in
real-time and to control some context information processed in real-time.
NOTE 3: Each functional block has its unique name, Input, Output, and properties.
peer equipment: any communication counterpart of a reconfigurable radio equipment
NOTE: The peer equipment can be reached by establishing a (logical) communications link (i.e. an association)
between the reconfigurable radio equipment and peer equipment. Examples of peer equipment include
Wide Local Area Network (WLAN) access points, Internet Protocol (IP) access nodes, etc.

SIST EN 303 095 V1.3.1:2018
8 ETSI EN 303 095 V1.3.1 (2018-05)
Radio Application (RA): software which enforces the generation of the transmit RF signals or the decoding of the
receive RF signals
NOTE 1: The software is executed on a particular radio platform or an RVM as part of the radio platform.
NOTE 2: RAs might have different forms of representation. They are represented as:
Source codes including Radio Library calls of Radio Library native implementation and Radio
HAL calls.
IRs including Radio Library calls of Radio Library native implementation and radio HAL calls.
Executable codes for a particular radio platform.
radio computer: part of mobile device hardware working under ROS control and on which RAs are executed
NOTE: A Radio Computer typically include programmable processors, hardware accelerators, peripherals, etc.
RF part is considered to be part of peripherals.
Radio Control Framework (RCF): control framework which, as a part of the OS, extends OS capabilities in terms of
radio resource management
NOTE: RCF is a control framework which consists of Configuration Manager (CM), Radio Connection Manager
(RCM), Flow Controller (FC) and Multiradio Controller (MRC). The Resource Manager (RM) is
typically part of OS.
Radio Controller (RC): functional component of RA for transferring context information from corresponding RAs to
monitor
NOTE: An RC, which may operate in an application processor in non real-time, accesses RAs which operates in
Radio Computer in real time. The monitor, to which the context information is transferred using RC,
provides context information to Adminstrator and/or Mobility Policy Manager (MPM) for application(s)
to be performed using the context information, for example, terminal-centric configuration.
Radio Frequency Transceiver (RF Transceiver): part of radio Platform converting, for transmission, baseband
signals into radio signals, and, for reception, radio signals into baseband signals
Radio Library (RL): library of SFB that is provided by a platform vendor in a form of platform-specific executable
code
NOTE 1: SFBs implement reference codes of functions which are typical for radio signal processing. They are not
atomic and their source codes are typed and visible for RA developers.
NOTE 2: An SFB is implemented through a Radio Hardware Abstraction Layer (HAL) when the SFB is
implemented on hardware accelerators. Radio HAL is part of ROS.
Radio Operating System (ROS): any appropriate OS empowered by RCF
NOTE: ROS provides RCF capabilities as well as traditional management capabilities related to management of
RP such as resource management, file system support, unified access to hardware resources, etc.
radio platform: part of mobile device hardware which relates to radio processing capability, including programmable
components, hardware accelerators, RF transceiver, and antenna(s)
NOTE: A radio Platform is a piece of hardware capable of generating RF signals or receiving RF signals. By
nature, it is heterogeneous hardware including different processing elements such as fixed accelerators,
e.g. Application-Specific Integrated Circuit (ASIC), or reconfigurable accelerators, e.g. FPGAs, etc.
Radio Virtual Machine (RVM): abstract machine which supports reactive and concurrent executions
NOTE: An RVM may be implemented as a controlled execution environment which allows the selection of a
trade-off between flexibility of base band code development and required (re-)certification efforts.

reconfigurable mobile device: mobile device with radio communication capabilities providing support for radio
reconfiguration
NOTE: Reconfigurable mobile devices include but are not limited to: smartphones, feature phones, tablets, and
laptops.
reference point: conceptual point at the conjunction of two non-overlapping functions that can be used to identify the
type of information passing between these functions
NOTE: This definition is introduced by Recommendation ITU-T M.60 [i.3].
shadow radio platform: platform where configcodes can be directly executed when it corresponds to the target radio
platform or, when it corresponds to an RVM, compiled and executed
NOTE: If the Shadow radio platform is equivalent to the target radio platform, then a front-end compiler will
generate the executable code for the target radio platform and configcodes are equivalent to the
executable code for that radio platform.

4.1 Introduction
The present document describes those elements of a mobile device which are related to the software radio
reconfiguration only. For this reason,the usage of the term "architecture" is limited to those elements and not to the
overall HW/SW architecture of a mobile device which is out of the scope of the present document.
The present document is organized as follows:
Clause 4.2 describes the reconfigurable mobile device architecture in term of its components and entities.
Clause 4.3 describes the architecture reference model for multiradio applications.
Clause 4.4 describes the "Radio Computer".
Clause 4.5 describes the Radio Virtual Machine as part of the architecture.
Clause 4.6 describes the Unified Radio Application.
Clause 4.7 describes the security architecture for reconfigurable mobile devices.
Clause 5 describes the (logical) interfaces between the identified components/entities.

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Application Processor (AP): part of mobile device hardware working under OS control and on which User
Applications, among others, are executed
Baseband Parameter Aggregation (BPA): unit collecting all the context information to be transferred to the monitor
NOTE: The BPA unit converts the context information into metric(s) such that a minimum bandwidth is
consumed during the procedure of transferring the context information to the monitor. Those metrics may
include Received Signal Strength Indication (RSSI) measurement, multi-RAT performance metrics, etc.
communication services layer: layer related to communication services supporting generic applications
NOTE: A communication services layer supports generic applications like Internet access. In the present
document, it consists of Administrator, Mobility Policy Manager (MPM), Networking stack and Monitor.
configcodes: result of compiling the source codes of a Radio Application (RA), which is either configuration codes of
Radio Virtual Machine (RVM) or executable codes for a particular target platform
NOTE: In the case when RA provider makes a high level code based on a target platform, a result of compiling
RA source codes is configcodes which is executable on the target platform. In the other case, when RA
provider makes a high level code without considering a target platform, a result of front-end compiling of
RA source codes is an Intermediate Representation (IR) which should be back-end compiled for operating
on a specific target platform.
data flow: logical channel between Flow Controller (FC) and a Unified Radio Applications (URA) created by FC to
send to or receive data elements (octets, packets or other granularity) from URA
environmental information: set of values that can affect the execution of RAs on a Radio Computer
NOTE: Environmental information consists of information related to the execution of RA(s), such as Buffer
Overflow, Resource Allocation, etc.
Functional Block (FB): function needed for real-time implementation of RA(s)
NOTE 1: A functional block includes not only the modem functions in Layer1 (L1), Layer2 (L2), and Layer 3 (L3)
but also all the control functions that should be processed in real-time for implementing given RA(s).
NOTE 2: Functional blocks are categorized into Standard Functional Blocks (SFBs) and User Defined Functional
Blocks (UDFBs). In more details:
1) SFB can be shared by many RAs. For example, Forward Error Correction (FEC), Fast Fourier
Transform (FFT)/Inverse Fast Fourier Transform (IFFT), (de)interleaver, Turbo coding, Viterbi
coding, Multiple Input Multiple Output (MIMO), Beamforming, etc. are the typical category of
standard functional block.
2) UDFB include those functional blocks that are dependent upon a specific RA. They are used to
support special function(s) required in a specific RA or to support a special algorithm used for
performance improvement. In addition, a user defined functional block can be used as a baseband
controller functional block which controls the functional blocks operating in baseband processor in
real-time and to control some context information processed in real-time.
NOTE 3: Each functional block has its unique name, Input, Output, and properties.
peer equipment: any communication counterpart of a reconfigurable radio equipment
NOTE: The peer equipment can be reached by establishing a (logical) communications link (i.e. an association)
between the reconfigurable radio equipment and peer equipment. Examples of peer equipment include
Wide Local Area Network (WLAN) access points, Internet Protocol (IP) access nodes, etc.

8 ETSI EN 303 095 V1.3.1 (2018-05)
Radio Application (RA): software which enforces the generation of the transmit RF signals or the decoding of the
receive RF signals
NOTE 1: The software is executed on a particular radio platform or an RVM as part of the radio platform.
NOTE 2: RAs might have different forms of representation. They are represented as:
Source codes including Radio Library calls of Radio Library native implementation and Radio
HAL calls.
IRs including Radio Library calls of Radio Library native implementation and radio HAL calls.
Executable codes for a particular radio platform.
radio computer: part of mobile device hardware working under ROS control and on which RAs are executed
NOTE: A Radio Computer typically include programmable processors, hardware accelerators, peripherals, etc.
RF part is considered to be part of peripherals.
Radio Control Framework (RCF): control framework which, as a part of the OS, extends OS capabilities in terms of
radio resource management
NOTE: RCF is a control framework which consists of Configuration Manager (CM), Radio Connection Manager
(RCM), Flow Controller (FC) and Multiradio Controller (MRC). The Resource Manager (RM) is
typically part of OS.
Radio Controller (RC): functional component of RA for transferring context information from corresponding RAs to
monitor
NOTE: An RC, which may operate in an application processor in non real-time, accesses RAs which operates in
Radio Computer in real time. The monitor, to which the context information is transferred using RC,
provides context information to Adminstrator and/or Mobility Policy Manager (MPM) for application(s)
to be performed using the context information, for example, terminal-centric configuration.
Radio Frequency Transceiver (RF Transceiver): part of radio Platform converting, for transmission, baseband
signals into radio signals, and, for reception, radio signals into baseband signals
Radio Library (RL): library of SFB that is provided by a platform vendor in a form of platform-specific executable
code
NOTE 1: SFBs implement reference codes of functions which are typical for radio signal processing. They are not
atomic and their source codes are typed and visible for RA developers.
NOTE 2: An SFB is implemented through a Radio Hardware Abstraction Layer (HAL) when the SFB is
implemented on hardware accelerators. Radio HAL is part of ROS.
Radio Operating System (ROS): any appropriate OS empowered by RCF
NOTE: ROS provides RCF capabilities as well as traditional management capabilities related to management of
RP such as resource management, file system support, unified access to hardware resources, etc.
radio platform: part of mobile device hardware which relates to radio processing capability, including programmable
components, hardware accelerators, RF transceiver, and antenna(s)
NOTE: A radio Platform is a piece of hardware capable of generating RF signals or receiving RF signals. By
nature, it is heterogeneous hardware including different processing elements such as fixed accelerators,
e.g. Application-Specific Integrated Circuit (ASIC), or reconfigurable accelerators, e.g. FPGAs, etc.
Radio Virtual Machine (RVM): abstract machine which supports reactive and concurrent executions
NOTE: An RVM may be implemented as a controlled execution environment which allows the selection of a
trade-off between flexibility of base band code development and required (re-)certification efforts.

laptops.
reference point: conceptual point at the conjunction of two non-overlapping functions that can be used to identify the
type of information passing between these functions
NOTE: This definition is introduced by Recommendation ITU-T M.60 [i.3].
shadow radio platform: platform where configcodes can be directly executed when it corresponds to the target radio
platform or, when it corresponds to an RVM, compiled and executed
NOTE: If the Shadow radio platform is equivalent to the target radio platform, then a front-end compiler will
generate the executable code for the target radio platform and configcodes are equivalent to the
executable code for that radio platform.

The present document is organized as follows:
Clause 4.2 describes the reconfigurable mobile device architecture in term of its components and entities.
Clause 4.3 describes the architecture reference model for multiradio applications.
Clause 4.4 describes the "Radio Computer".
Clause 4.5 describes the Radio Virtual Machine as part of the architecture.
Clause 4.6 describes the Unified Radio Application.
Clause 4.7 describes the security architecture for reconfigurable mobile devices.
Clause 5 describes the (logical) interfaces between the identified components/entities.
Clause 6 lists the operating procedures of a reconfigurable mobile devices.
Clause 4 includes a list of tables mapping the system requirements as defined in ETSI EN 302 969 [1] to the different
entities/components/units which have been identified. In general, according to the MDRC [1] the reconfigurable mobile
device belongs to, all the related mandatory functional requirements described in ETSI EN 302 969 [1] shall be

coding, Multiple Input Multiple Output (MIMO), Beamforming, etc. are the typical category of
standard functional block.
2) UDFB include those functional blocks that are dependent upon a specific RA. They are used to
support special function(s) required in a specific RA or to support a special algorithm used for
performance improvement. In addition, a user defined functional block can be used as a baseband
controller functional block which controls the functional blocks operating in baseband processor in
real-time and to control some context information processed in real-time.
NOTE 3: Each functional block has its unique name, Input, Output, and properties.
peer equipment: any communication counterpart of a reconfigurable radio equipment
NOTE: The peer equipment can be reached by establishing a (logical) communications link (i.e. an association)
between the reconfigurable radio equipment and peer equipment. Examples of peer equipment include
Wide Local Area Network (WLAN) access points, Internet Protocol (IP) access nodes, etc.

Radio Application (RA): software which enforces the generation of the transmit RF signals or the decoding of the
receive RF signals
NOTE 1: The software is executed on a particular radio platform or an RVM as part of the radio platform.
NOTE 2: RAs might have different forms of representation. They are represented as:
Source codes including Radio Library calls of Radio Library native implementation and Radio
HAL calls.
IRs including Radio Library calls of Radio Library native implementation and radio HAL calls.
Executable codes for a particular radio platform.
radio computer: part of mobile device hardware working under ROS control and on which RAs are executed
NOTE: A Radio Computer typically include programmable processors, hardware accelerators, peripherals, etc.
RF part is considered to be part of peripherals.
Radio Control Framework (RCF): control framework which, as a part of the OS, extends OS capabilities in terms of
radio resource management
NOTE: RCF is a control framework which consists of Configuration Manager (CM), Radio Connection Manager
(RCM), Flow Controller (FC) and Multiradio Controller (MRC). The Resource Manager (RM) is
typically part of OS.
Radio Controller (RC): functional component of RA for transferring context information from corresponding RAs to
monitor
NOTE: An RC, which may operate in an application processor in non real-time, accesses RAs which operates in
Radio Computer in real time. The monitor, to which the context information is transferred using RC,
provides context information to Adminstrator and/or Mobility Policy Manager (MPM) for application(s)
to be performed using the context information, for example, terminal-centric configuration.
Radio Frequency Transceiver (RF Transceiver): part of radio Platform converting, for transmission, baseband
signals into radio signals, and, for reception, radio signals into baseband signals
Radio Library (RL): library of SFB that is provided by a platform vendor in a form of platform-specific executable
code
NOTE 1: SFBs implement reference codes of functions which are typical for radio signal processing. They are not
atomic and their source codes are typed and visible for RA developers.
NOTE 2: An SFB is implemented through a Radio Hardware Abstraction Layer (HAL) when the SFB is
implemented on hardware accelerators. Radio HAL is part of ROS.
Radio Operating System (ROS): any appropriate OS empowered by RCF
NOTE: ROS provides RCF capabilities as well as traditional management capabilities related to management of
RP such as resource management, file system support, unified access to hardware resources, etc.
radio platform: part of mobile device hardware which relates to radio processing capability, including programmable
components, hardware accelerators, RF transceiver, and antenna(s)
NOTE: A radio Platform is a piece of hardware capable of generating RF signals or receiving RF signals. By
nature, it is heterogeneous hardware including different processing elements such as fixed accelerators,
e.g. Application-Specific Integrated Circuit (ASIC), or reconfigurable accelerators, e.g. FPGAs, etc.
Radio Virtual Machine (RVM): abstract machine which supports reactive and concurrent executions
NOTE: An RVM may be implemented as a controlled execution environment which allows the selection of a
trade-off between flexibility of base band code development and required (re-)certification efforts.

reconfigurable mobile device: mobile device with radio communication capabilities providing support for radio
reconfiguration
NOTE: Reconfigurable mobile devices include but are not limited to: smartphones, feature phones, tablets, and
laptops.
reference point: conceptual point at the conjunction of two non-overlapping functions that can be used to identify the
type of information passing between these functions
NOTE: This definition is introduced by Recommendation ITU-T M.60 [i.3].
shadow radio platform: platform where configcodes can be directly executed when it corresponds to the target radio
platform or, when it corresponds to an RVM, compiled and executed
NOTE: If the Shadow radio platform is equivalent to the target radio platform, then a front-end compiler will
generate the executable code for the target radio platform and configcodes are equivalent to the
executable code for that radio platform.

The present document is organized as follows:
Clause 4.2 describes the reconfigurable mobile device architecture in term of its components and entities.
Clause 4.3 describes the architecture reference model for multiradio applications.
Clause 4.4 describes the "Radio Computer".
Clause 4.5 describes the Radio Virtual Machine as part of the architecture.
Clause 4.6 describes the Unified Radio Application.
Clause 4.7 describes the security architecture for reconfigurable mobile devices.
Clause 5 describes the (logical) interfaces between the identified components/entities.
Clause 6 lists the operating procedures of a reconfigurable mobile devices.
Clause 4 includes a list of tables mapping the system requirements as defined in ETSI EN 302 969 [1] to the different
