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.

broadcast identifier (broadcast ID): identifier linking a data packet to all available radio computers

Communication Services Layer (CSL): 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.

computational resources: part of Radio Equipment hardware working under OS control and on which Applications,

configcodes: result of compiling the source codes of a Radio Application (RA), which is either configuration codes of

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

data flow: logical channel between Flow Controller (FC) and an Unified Radio Applications (URA) created by FC to

distributed computations: computational model in which components located on networked computers communicate

and coordinate their actions by passing messages interacting with each other in order to achieve a common goal

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

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

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

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

NOTE 3: Each functional block has its unique name, Input, Output, and properties.

multicast identifier (multicast ID): identifier linking a data packet to a group of radio computers

NOTE: A group of radio computers consists of at least two radio computers. The way for implementing the radio

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

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

 IRs including Radio Library calls of Radio Library native implementation and radio HAL calls;

radio computer: part of Radio Equipment working under ROS control and on which RAs are executed

NOTE 1: A radio computer typically includes programmable processors, hardware accelerators, peripherals,

Radio Control Framework (RCF): control framework which, as a part of the OS, extends OS capabilities in terms of

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

Radio Controller (RC): functional component of RA for transferring context information from corresponding RAs to

NOTE: A RC, which may operate in computational resources 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 Administrator and/or Mobility Policy Manager (MPM) for application(s)

to be performed using the context information, for example, terminal-centric configuration.

Radio Equipment (RE): As defined in the Radio Equipment Directive, Article 2(1)(1) [i.8].

NOTE: Excerpt from the Radio Equipment Directive: "'radio equipment' means an electrical or electronic

product, which intentionally emits and/or receives radio waves for the purpose of radio communication

and/or radiodetermination, or an electrical or electronic product which must be completed with an

accessory, such as antenna, so as to intentionally emit and/or receive radio waves for the purpose of

radio frequency transceiver (RF transceiver): part of Radio Platform converting, for transmission, baseband signals

radio library: 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

NOTE 2: A SFB is implemented through a Radio Hardware Abstraction Layer (HAL) when the SFB is

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 Radio Equipment hardware which relates to radio processing capability, including

programmable hardware components, hardware accelerators, RF transceiver, and antenna(s)

NOTE 1: A Radio Platform is a piece of hardware capable of generating RF signals or receiving RF signals,

including Base-Band and RF processing. By nature, it is heterogeneous hardware including different

processing elements such as fixed accelerators, e.g. Application-Specific Integrated Circuit (ASIC), or

NOTE 2: In case of multiple radio computers, there is an independent Radio Platform for each of the radio

Radio Virtual Machine (RVM): abstract machine which supports reactive and concurrent executions

NOTE: A 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 Radio Equipment: Radio Equipment with radio communication capabilities providing support for

NOTE: Reconfigurable Radio Equipment includes Smartphones, Feature phones, Tablets, Laptops, Connected

reference point: conceptual point at the conjunction of two non-overlapping functions that can be used to identify the
