Abstract
Described is a method of decoding a physical sidelink shared channel (PSSCH) involving physical sidelink control channel (PSCCH) resource grid search space reduction, timing offset (TO) estimation, and reference symbol identification. Resource grid search space reduction may include identifying resource blocks (RBs) having a signal power below a first threshold such that said RBs can be excluded from further processing. Search space reduction may additionally or alternatively include identifying RB pairs where a difference in signal power between the RBs comprising each pair of RBs is above a second threshold and excluding any such said RB pairs from further processing. TO compensation may include circularly correlating TO-compensated received DMRSs and their corresponding local DMRSs to obtain energy or power profiles. From the energy/power profiles, a subset L of highest stored power values and their corresponding cyclic shift (n) values can be chosen where said power values are equal to or exceed a third threshold. The selected subset L can be made available for use in a decoding process for a received channel signal.
