3 Definitions and abbreviations p. 6

3.1 Definitions p. 6

For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.

Carrier frequency:

center frequency of the cell.

Frequency layer:

set of cells with the same carrier frequency.

NB-IoT:

NB-IoT allows access to network services via E-UTRA with a channel bandwidth limited to 200 kHz.

Short Processing Time:

For 1 ms TTI length, the operation with short processing time in UL data transmission and DL data reception.

Short TTI:

TTI length based on a slot or a subslot.

Sidelink:

UE to UE interface for sidelink communication, V2X sidelink communication and sidelink discovery. The sidelink corresponds to the PC5 interface as defined in TS 23.303.

Sidelink communication:

AS functionality enabling ProSe Direct Communication as defined in TS 23.303, between two or more nearby UEs, using E-UTRA technology but not traversing any network node. In this version, the terminology "sidelink communication" without "V2X" prefix only concerns PS unless explicitly stated otherwise.

Sidelink discovery:

AS functionality enabling ProSe Direct Discovery as defined in TS 23.303, using E-UTRA technology but not traversing any network node.

V2X Sidelink communication:

AS functionality enabling V2X Communication as defined in TS 23.285, between nearby UEs, using E-UTRA technology but not traversing any network node.

Timing Advance Group:

See the definition in TS 36.321.

Transmission using PUR:

Allows one uplink data transmission using preconfigured uplink resource from RRC_IDLE mode as specified in TS 36.300. Transmission using PUR refers to both CP transmission using PUR and UP transmission using PUR.

5 Services and functions of the physical layer p. 8

5.1 General p. 8

The physical layer offers data transport services to higher layers.

The access to these services is through the use of transport channels via the MAC sub-layer.

A transport block is defined as the data delivered by MAC layer to the physical layer and vice versa. Transport blocks are delivered once every TTI.

5.2 Overview of L1 functions p. 8

The physical layer offers data transport services to higher layers. The access to these services is through the use of a transport channel via the MAC sub-layer. The physical layer is expected to perform the following functions in order to provide the data transport service:

Error detection on the transport channel and indication to higher layers
FEC encoding/decoding of the transport channel
Hybrid ARQ soft-combining
Rate matching of the coded transport channel to physical channels
Mapping of the coded transport channel onto physical channels
Power weighting of physical channels
Modulation and demodulation of physical channels
Frequency and time synchronisation
Radio characteristics measurements and indication to higher layers
Multiple Input Multiple Output (MIMO) antenna processing
Transmit Diversity (TX diversity)
Beamforming
RF processing.

L1 functions are modelled for each transport channel in clause 6.1, clause 6.2 and clause 6.3.
