Title: 2-stage sci for v2x communication
Inventor: CHEN TAO
IPC: H04W52/00
Filed: 2019-04-04
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 by applying the 1  st  SCI for the purpose of sensing and broadcast communication whereas the 2  nd  SCI carrying the remaining information for data scheduling of unicast/groupcast data transmission. The 2  nd  SCI time/frequency location can be derived from the information fields carried in the 1  st  SCI. Both 1  st  and 2  nd  SCIs can be transmitted using the centralized frequency resources or distributed frequency resources. The 1  st  SCI and 2  nd  SCI can be time domain multiplexed in different symbols and/or frequency domain multiplexed in different RBs (interleaved or non-interleaved). The 2  nd  SCI can have the link adaptation associated with the data channel link adaptation. 2  nd  SCI can have the same transmission scheme as the data channel with the same antenna port (s) or the different transmission scheme with different antenna port (s) but with the same power per resource element. Furthermore, power boosting can be applied between the sidelink control channel and data channel. The power offset can be indicated during the sidelink RRC connection setup for unicast/groupcast communication or indicated in the 1  st  SCI. DMRS location in frequency domain for the 1  st  SCI can be fixed. The reference signal for 2  nd  SCI decoding can reuse/share the data channel (PSSCH) DMRS wholly or partly with no need of the dedicated DMRS to reduce the overhead. The dest (or source) UE/group ID can be used for sequence generation of the data channel (and 2  nd  SCI) DMRS. The 2  nd  SCI can use the polar coding but share the time/frequency resources as the data channel. The shorter CRC (e. g, 16 bits CRC) can be applied for the 2  nd  SCI (and/or 1  st  SCI) to reduce the CRC overhead. It can be indicated in the 1  st  SCI whether the DMRS between 1  st  SCI and 2  nd  SCI/Data DMRS are QCL' ed or whether the same transmission scheme is used based on the same antenna port (s). Then the channel estimation for 2  nd  SCI/Data can use 1  st  SCI DMRS or not depending on the indication.
