Title: Control channel design for v2x communication
Inventor: CHEN TAO
IPC: H04W72/12
Filed: 2019-02-18
Abstract: For V2X sidelink communication, the sidelink physical data channel (PSSCH) can be scheduled by sidlelink control information (SCI) carried in sidelink physical control channel (PSCCH). 2-stage SCI can be used for such scheduling with the 1st SCI decodable for all UEs to carry Dest ID information, time-frequency resource allocation and priority information, etc. for sensing purpose and 2nd SCI decodable for the intended UEs to carry source ID information and others (e.g., RV, new data indicator, MCS) for detailed demodulation of PSSCH. Src ID can be implicitly carried via CRC scrambling in 2nd SCI to avoid overhead. Moreover, to support both the single SCI and 2-stage SCI, the format indicator of different RNTI can be used for differentiation. Further, for interference cancellation, the port information (port number) and/or DMRS pattern information can be carried in the SCI (e.g., 1st SCI). Single SCI may be used for broadcast communication with a common RNTI or L1-ID for identification, whereas the 2-stage SCI may be used for the unicast/groupcast communication with its own L1-ID or RNTI for differentiation.
