4 Introduction
A reconfigurable RE is capable of running multiple radios simultaneously, changing the set of radios by loading new
Radio Application Packages (RAP) and setting their parameters. All Radio Applications (RAs) are called Unified Radio
Applications (URAs) when they exhibit a common behaviour from the reconfigurable RE's point of view in ETSI
TS 103 648 [i.2]. In order to run multiple URAs, the reconfigurable RE will include Communication Services Layer
(CSL), Radio Control Frameworks (RCFs), Radio Platforms and 4 sets of interfaces for their interconnection.

Figure 4.1: Four sets of interfaces for Reconfigurable RE
Figure 4.1 illustrates the Reconfigurable RE architecture with the 4 sets of interfaces, i.e.:
• gMURI for interfacing CSL and RCF which is the scope of the present document.
• gRRFI for interfacing URA and RF Transceiver (in ETSI EN 303 681-2 [i.7]).
• gURAI for interfacing URA and RCF (in ETSI EN 303 681-3 [i.8]).
• gRPI for allowing an independent and uniform production of RAs (in ETSI EN 303 681-4 [i.9]).
The present document defines gMURI.

Figure 4.2: UML class diagram for Radio Computer interfaces
Figure 4.2 illustrates UML class diagram for Radio Computer interfaces. The reconfigurable RE may be seen as a set of
multiple Radio Computers where individual URAs are engineered as software entities in ETSI TS 103 648 [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 gMURI, other modeling languages could
be used as well.
5 System Identification
5.1 Radio Computer Structure
Figure 5.1 illustrates how CSL and RCFs interact with each other using gMURI.
ETSI
10 ETSI TS 103 681-1 V1.1.1 (2020-03)

Figure 5.1: Interconnection between CSL and RCF using gMURI for Reconfigurable RE
As shown in figure 5.1, gMURI supports 3 kinds of services:
• Administrative Services
- These services are used by some device configuration application i.e. Administrator which is included in
the CSL, to (un)install a new URA into the Reconfigurable RE and create/delete an instance of the URA.
Installation and loading may take place both at device start-up time to set up the network connection as
well as during run-time, whenever reconfiguration of available URAs is needed. gMURI does not make
any assumption on how and when the Radio Equipment will detect the need of the reconfiguration.
• Access Control Services
- These services are used by the MPM to maintain the user policies and preferences related to the usage of
different RATs and to make a selection between them. Modelling of such preferences and selection
algorithms is not in the scope of the present document; however, the gMURI specification covers the
information exchange of RAT selection decisions between CSL and RCF. The preferences themselves
may originate either locally from applications or end user settings as well as in a distributed manner from
network operator or from a cognitive radio management framework.
• Data Flow Services
- These services are used by the networking stack of the Reconfigurable RE, such as the TCP/IP stack.
Therefore data flow services represent the set of (logical) link layer services, which are provided in a
uniform manner regardless of which URAs are active.
The Communication Services Layer (CSL) and Radio Control Framework (RCF) are defined in ETSI TS 103 648 [i.2].

• Link
- This class contains information about one active URA and the corresponding connection between the
Reconfigurable RE and the Radio Access Network (RAN). Each instance of RCConfiguration class has
zero, one or several instances of Link class as members (0.*). Each instance of Link class is associated
with one instance of Channel class.
• LinkProfile
- This class contains general information about this active connection, for example, link Identification
(ID), serving cell ID, channel used, etc. Each instance of Link class shall have only one instance of
LinkProfile class as a member.
• LinkMeasurements
- This class contains current measurements (instantaneous measurement data and related metadata) related
to this active connection, such as Block Error Rate (BLER), power, and Signal to Interference plus Noise
Ratio (SINR) measurements. Each instance of Link class shall have only one instance of
LinkMeasurements class as a member.
• RFConfiguration
- This class contains information about the configuration of the RF transceiver. Each instance of Link class
shall have only one instance of RFConfiguration class as a member.
• TxPath
- This class contains information about one transmit path. Each instance of RFConfiguration class has zero
or one instance of TxPath class as a member (0,1).
• RxPath
- This class contains information about one receive path. Each instance of RFConfiguration class shall
have only one instance of RxPath class as a member.
• RCMeasurements
- This class contains current measurements (instantaneous measurement data and related metadata) related
to Reconfigurable RE such as battery capacity, user mobility, RE location determination, and connection
history information. Each instance of RadioComputer class shall have only one instance of
RCMeasurements class as a member.
NOTE: The Channel Class is separate from the Link Class, but the Channel Measurements may be based on any
RE configuration which may or may not be used for the final Link Configuration.
7.3 Class Definitions for Information Model
Each class of Radio Computer can be defined using the template presented in clause 6.1 and in accordance with the
UML diagram of figure 7.2 which specifies the relations among all the classes of Radio Computer. Radio Computer
classes defined in this way are shown in tables 7.1 to 7.17.
