No user data transfer may occur with only an association present, but a data flow may be established into an association for this purpose. NOTE 2: Peer equipment is any communication counterpart of a reconfigurable mobile device. It can be reached by establishing a logical communication link (i.e. an association) between the reconfigurable mobile device and peer equipment. channel: designated part of the information transfer capability having specified characteristics, provided at the user network interface NOTE: It is the over-the-air wireless propagation channel which is used to convey an information signal from transmitter to receiver. This definition is specified in ETSI EN 303 095 [i.2]. 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. link: connection from one location to another through a given Radio Access Technology for the purpose of transmitting and receiving digital information 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 includes 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. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ASN Abstract Syntax Notation ASN.1 Abstract Syntax Notation One BLER BLock Error Rate SIST EN 303 146-3 V1.2.1:2016

All Radio Applications (RAs) are called Unified Radio Applications (URAs) when they exhibit a common behaviour from the reconfigurable MD's point of view [i.2]. In order to run multiple URAs, the reconfigurable MD will include Communication Services Layer (CSL), Radio Control Framework (RCF), Radio Platform and 4 sets of interfaces for their interconnection. SIST EN 303 146-3 V1.2.1:2016

Figure 4.1: Four sets of interfaces for Reconfigurable MD Figure 4.1 illustrates the Reconfigurable MD architecture with the 4 sets of interfaces, i.e.: • MURI for interfacing CSL and RCF [i.3]; • RRFI for interfacing URA and RF Transceiver [i.4]; • URAI for interfacing URA and RCF which is the scope of the present document; • RPI for allowing an independent and uniform production of RAs [i.5]. The present document defines URAI. SIST EN 303 146-3 V1.2.1:2016

The reconfigurable MD may be seen as a Radio Computer where individual URAs are engineered as software entities [i.2]. The present document is organized as follows: • clause 5 describes the system identification; • clause 6 describes the notational tool for defining both information model classes and interface classes; • clause 7 describes the information model for radio computer; and • clause 8 describes the interface definition. While UML is used for defining the information model and protocol related to URAI, other modelling languages could be used as well. 5 System Identification 5.1 Radio Computer Structure Figure 5.1 illustrates how RCF and URA interact with each other using URAI. SIST EN 303 146-3 V1.2.1:2016

Figure 5.1: Interconnection between RCF and URA using URAI for Reconfigurable MD As shown in figure 5.1, URAI supports 3 kinds of services: • Radio Application Management Services These services are used by Radio Connection Manager (RCM) which is included in the RCF, to control URA functions such as reporting of discovered Peer Equipments, creating/terminating association with Peer Equipment, starting/stopping communication with Peer Equipment, etc. • User Data Flow Services These services are used by Flow Controller (FC) which is included in the RCF, to transmit user data to URA, or used by URA to transmit received user data to FC. These services also include management of data flow, which is provided by FC. • Multiradio Control Services These services are used by Multiradio Controller (MRC) which is included in RCF, to manage spectral resource usage. The RCF and URA are defined in ETSI EN 303 095 [i.2]. 5.2 URAI System Requirement Mapping The Radio Computer components above described shall support the URAI system requirements shown in table 5.1 and described in clause 6 of ETSI EN 302 969 [1].
