Additionally or alternately, DCI may indicate all or part of the following information to a transmitter UE 102 (e.g., UE1) if the gNB 160 can control the transmitter UE 102 (in-coverage case, for instance): BWP identity (BWP ID); waveform (e.g., CP-OFDM or DFT-S-OFDM); DMRS type (e.g., DMRS type 1 and DMRS type 2 are specified in Uu interface, and which type is used for PSCCH or PSSCH); and/or the number of OFDM symbols for DMRS.
For SCI in a PSCCH, all or part of the following information may be indicated to a receiver UE 102 (e.g., UE2): MCS; scheduled resource within a resource pool (e.g., this may be a time resource pattern); DMRS type (e.g., type 1 and type 2); the number of OFDM symbols for DMRS type 1 or type 2; and/or waveform.
A time domain pattern may be defined as a bitmap (b0, b1, . . . , bL). If b1=1, the time unit for sidelink scheduling within a resource pool may be used for PSSCH transmission. On the other hand, if b1=0, the time unit for sidelink scheduling within a resource pool may not be used for PSSCH transmission. Additionally or alternately, a frequency domain pattern may be defined. In this case, each bit in a bitmap of the frequency domain pattern may be applied to each PRB or each group of PRBs including a plurality of continuous/non-continuous PRBs.
The UE operations module 124 may provide information 148 to the one or more receivers 120. For example, the UE operations module 124 may inform the receiver(s) 120 when to receive retransmissions.
