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 (n) 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 (n) values are made available for use in a decoding process for the received channel signal.

Systems and methods which provide for accurate decoding of a received channel signal when station identifier information is unknown. Embodiments accurately decode a physical downlink control channel (PDCCH), such as to obtain downlink control information (DCI), without knowing radio network temporary identifier (RNTI) information. An unknown station identifier information (USII) of embodiments uses redundancy reduction-based error checking (performing error checking between data decoded from a candidate control channel data block containing redundant data and a portion of that candidate control channel data block containing redundancy reduced data) for implementing decoding when station identifier information is unknown. Embodiments of a USII decoder may use a power detection technique for identifying candidate control channel data blocks used in redundancy reduction-based error checking operation.
