Bandwidth part configurations for V2X communication
摘要
說明書
A PSS and a SSS may be used for time/frequency synchronization and determination/detection of a physical cell identity (PCID). The PSS, the SSS, and the PBCH may be multiplexed as a SS/PBCH block, and one or more SS/PBCH blocks may be transmitted in a serving cell. A TRS may be used for channel tracking at a UE side and transmitted in the downlink, and the TRS may be one configuration of a CSI-RS resource. A CSI-RS may be used for measuring channel state information (CSI) and transmitted in the downlink and a CSI-RS includes non-zero power CSI-RS for channel measurement or interference measurement, zero-power CSI-RS (ZP CSI-RS) for interference measurement. A DMRS may be used for demodulation of physical channels, and the DMRS may be defined for each channel. A PTRS may be used for phase tracking to compensate phase noise and transmitted with DMRS and PDSCH/PUSCH. The PTRS may be configured in FR2. A SRS may be used for channel sounding in the uplink.
DCI may include scheduling information of a PDSCH or a PUSCH, the timing of HARQ-ACK (hybrid automatic repeat request-acknowledgement) bit(s), and modulation and coding schemes (MCS), DMRS port information, and so on. UCI may include HARQ-ACK bits and CSI. CSI may include one or more of CQI (channel quality indicator), PMI (precoding matrix indicator), RI (rank indicator), LI (layer indicator), and CRI (CSI-RS index).
For support of V2X communication, the following physical channels may be defined: physical sidelink broadcast channel (PSBCH); physical sidelink control channel (PSCCH); and/or physical sidelink shared channel (PSSCH).
