3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
camping on a cell: having completed the cell selection/reselection process and having chosen a cell
NOTE 1: In the framework of 3GPP, this term is defined in TS 125 304 [i.2] as follows: UE has completed the cell
selection/reselection process and has chosen a cell. The UE monitors system information and (in most
cases) paging information".
NOTE2: In addition to the context defined in 3GPP, the term "Camping" is here also used in the context of any
type of association to any other wireless system, such as WiFi, etc.
context information: cross-technology context information
NOTE 1: The availability and selected inherent operational parameters of heterogeneous Radio Access
Technologies (RATs) is an example.
NOTE 2: The term does not address 3GPP specific context information which is assumed not to be available for the
SDR Reference Architecture inherent decision making.
Mobile Network Operator (MNO): potential user for a specific use case
Network management system: network Management of one or more Reconfigurable Radio Systems
Reconfigurable Radio System (RRS): radio system using reconfigurable radio technology
system use case: use case describing the system functionality level and specifying the function or the service that the
system provides for the user
NOTE: A system use case will describe what the actor achieves interacting with the system. For this reason it is
recommended that a system use case specification begin with a verb (e.g. create voucher, select
payments, exclude payment, cancel voucher). Generally, the actor could be a human user or another
system interacting with the system being defined.
use case: description of a system from a user's perspective
NOTE 1: Use cases treat a system as a black box, and the interactions with the system, including system responses,
are perceived as from outside the system. Use cases typically avoid technical jargon, preferring instead
the language of the end user or domain expert.
NOTE 2: Use cases should not be confused with the features/requirements of the system under consideration. A use
case may be related to one or more features/requirements, a feature/requirement may be related to one or
more use cases.
NOTE 3: A brief use case consists of a few sentences summarizing the use case.
user: it represents the User of the Mobile Network

4 Reconfigurable Radio Systems operating in licensed
spectrums
4.1 General description and reference to past work
TR 102 680 [i.1] details an SDR Architecture for Mobile Device, highlighting in particular a set of 5 requirement
groups:
• General architectural requirements.
• Capability requirements.
• Operational requirements.
• Interface requirements.
• Other requirements.
Based on these requirement groups, an SDR Architecture has been defined as it is presented in detail by [i.1] and briefly
summarized in clause 4.2. The refined understanding of the final architecture proposal and the corresponding inherent
capabilities that were developed during the creation of [i.1] lead to the decision to create the present document for
giving a detailed overview on related use cases and scenarios.
4.2 Example of a typical Reconfigurable Radio Systems
capabilities
The following capabilities of Reconfigurable Radio Systems have been derived in [i.1] for a Mobile Device:
a) Multiradio configuration capability: SDR equipment in mobile device is expected to install, load and
activate a radio application while running a set of radio systems already.
b) Multiradio operation capability: SDR equipment in mobile device is expected to execute a number of radio
systems simultaneously by taking into account temporal coexistence rules designed for their common
operation.
c) Multiradio resource sharing capability: SDR equipment in mobile device is expected to execute a number
of radio systems simultaneously by sharing computation, memory, communications and RF circuitry resources
available on the radio computer platform by using appropriate resource allocation, binding and scheduling
mechanisms.
ETSI
8 ETSI TR 103 062 V1.1.1 (2011-04)
Building on these requirements, the following components are introduced in [i.1], also illustrated by:
1) Configuration Manager: (de)installation and (un)loading of radio applications into radio computer as well as
management of and access to the radio parameters of those radio applications.
2) Radio Connection Manager: (de)activation of radio applications according to user requests and overall
management of user data flows, which can also be switched from one radio application to another.
3) Flow Controller: sending and receiving of user data packets and controlling the flow.
4) Multiradio Controller: scheduling the requests on spectrum resources issued by concurrently executing radio
applications in order to detect in advance the interoperability problems between them.
5) Resource Manager: management of radio computer resources in order to share them among simultaneously
active radio applications, while guaranteeing their real-time requirements.

Figure 1: Functional Architecture of SDR Equipment
Furthermore, [i.1] identifies four candidate interfaces for standardization:
a) Multiradio Interface as the uniform interface for network protocol stacks and other user domain entities to
access services of the radio computer.
b) Unified Radio Application Interface at the boundary between the common radio computer platform and the
specific radio applications.
c) Radio Programming Interface including software development-time concepts and run-time interfaces
between radio software entities and radio computer platform.
d) Interface to the Reconfigurable RF Transceiver to support multiple radio applications, even concurrently.
Among these interfaces, the Multiradio Interface has most potential for standardization. It is expected to enable an
easier integration of radio platforms into handsets that benefits both chipset vendors and device manufacturers;
moreover, it offers significant functionality on top of SDR. Common methods of accessing the SDR services ease the
definition and deployment of cognitive radio, providing capability to implement the functionality independently on both
sides of the interface.
ETSI
9 ETSI TR 103 062 V1.1.1 (2011-04)
The deployment of the Multiradio Interface is expected to proceed in phases with platform capability advancing,
starting from legacy radio access technologies, gradually moving towards a full SDR:
1) Radio applications use pre-defined fixed resources. Radio applications come from a single source, and a list of
concurrently supported radios is provided. Additional CR functionality is introduced by means of parameter
management of individual radio applications.
2) Radio applications have fixed resource requirements. Instead of fixed resources, a worst-case resource
consumption budget is attached t
