41、ions of the physical layer 5.1 General 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

42、. Transport blocks are delivered once every TTI. 5.2 Overview of L1 functions 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 func

43、tions 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 tra

44、nsport 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 - Trans

45、mit Diversity (TX diversity) - Beamforming - RF processing. L1 functions are modelled for each transport channel in subclauses 6.1, 6.2 and 6.3. ETSI ETSI TS 136 302 V13.4.0 (2017-02)93GPP TS 36.302 version 13.4.0 Release 135.3 Void 6 Model of physical layer of the UE The E-UTRA physical-layer model

46、 captures those characteristics of the E-UTRA physical-layer that are relevant from the point-of-view of higher layers. More specifically, the physical-layer model captures: - The structure of higher-layer data being passed down to or up from the physical layer; - The means by which higher layers ca

47、n configure the physical layer; - The different indications (error indications, channel-quality indications, etc.) that are provided by the physical layer to higher layers; - Other (non-transport-channel-based) higher-layer peer-to-peer signalling supported by the physical layer. 6.1 Uplink model 6.

48、1.1 Uplink Shared Channel The physical-layer model for Uplink Shared Channel transmission is described based on the corresponding physical-layer-processing chain, see Figure 6.1.1-1. Processing steps that are relevant for the physical-layer model, e.g. in the sense that they are configurable by high

49、er layers, are highlighted in blue. It should be noted that, in the cases of PUSCH and NPUSCH, the scheduling decision is fully done at the network side. The uplink transmission control in the UE then configures the uplink physical-layer processing, based on uplink transport-format and resource-assignment information received on the downlink. - Higher-layer data passed to/from the physical layer - One transport block of dynamic size delivered to the physical layer once every TTI. - CRC and transport-block-error indication
