Abstract
Described is a method of decoding a physical sidelink control channel (PSCCH). The method comprises: for a PSCCH candidate in a resource grid, processing a received demodulation reference signal (DMRS) in a subframe of the resource grid associated with the PSCCH candidate to determine one or more potential PSCCHs for decoding, each of the one or more potential PSCCHs being identified by resource block (RB) position in the resource grid and a corresponding DMRS cyclic shift (ncs) value. This step is repeated for at least one other DMRS in the subframe to determine one or more potential PSCCHs for the at least one other DMRS. Then, a subset L of PSCCHs is selected from the potential PSCCHs. The selected subset L of PSCCHs together with their corresponding DMRS cyclic shift (ncs) values are made available for use in a decoding process for the received channel signal.
