Abstract: Embodiments of the present disclosure relate to at least one evaluation period, a detection period with allowed dropping rate or a measurement period determination. A terminal device measures a reference signal receives power (RSRP) associated with a physical sidelink broadcast channel (PSBCH) of a synchronization reference device, determines a number of consecutive periods associated with a listen before talk (LBT) failure in which a sidelink synchronization signal (SLSS) is unavailable from the synchronization reference device, and determines, based on the number of consecutive periods, at least one of an evaluation period, a detection period with allowed dropping rate or a measurement period for evaluating the RSRP, wherein the consecutive periods correspond to a plurality of consecutive sidelink synchronization signal block (S-SSB) periods or a plurality of consecutive discontinuous reception (DRX) cycles. Thus, wrong initiation of SLSS transmission event and wrong reselection of a SyncRef UE may be avoided.
