Abstract: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for 5G-NR sidelink communications, the processing circuitry is to decode SCI received from a second UE via a PSCCH, the SCI indicating a sidelink resource for transmission of a transport block during multiple transmission time intervals, and a PSFCH indicator. A PSSCH is decoded to obtain the transport block, the PSSCH received in one of the multiple transmission time intervals using frequency resource assignment and time resource assignment of the sidelink resource. HARQ feedback information for the decoded PSSCH is encoded for transmission to the second UE using a PSFCH associated with the sidelink resource, based on the PSFCH indicator and a time gap configured by higher layer signaling.

A second message (MsgB) received from the gNB in response to the MsgA is decoded. The MsgB includes a random access response (RAR), the RAR being one of a fallbackRAR or a successRAR.
