1. An apparatus for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory and configured to cause the apparatus to:
measure (i) one of respective reference signal received powers (RSRPs) for each of a first sidelink (SL) transmission associated with a first user equipment (UE) and a second SL transmission associated with a second UE or (ii) at least one reference signal received quality (RSRQ) for at least one of the first SL transmission or the second SL transmission; and
detect at least one semi-persistent scheduling (SPS) conflict in a set of resources between the first SL transmission and the second SL transmission based on (i) a magnitude of a difference between the respective RSRPs being below a RSRP difference threshold in a set of RSRP difference thresholds or (ii) the at least one measured RSRQ being below an RSRQ threshold in a set of RSRQ thresholds,
wherein to detect the at least one SPS conflict between the first SL transmission and the second SL transmission, the one or more processors are configured to cause the apparatus to determine if the first SL transmission and the second SL transmission are configured to result in a number of conflicts over a period of time that is above a threshold number of conflicts; and
transmit, upon detection of the at least one SPS conflict, an indication of the SPS conflict to at least one of the first UE or the second UE, the indication of the SPS conflict including information regarding the detected at least one SPS conflict between the first SL transmission and the second SL transmission,
wherein:
(i) the set of RSRP difference thresholds comprises a first RSRP difference threshold configured to be applied when a pair of SL transmissions is determined to be configured to result in the number of conflicts over the period of time that is above the threshold number of conflicts, the set of RSRP difference thresholds comprises a second RSRP difference threshold configured to be applied when the pair of SL transmissions is determined to not be configured to result in the number of conflicts over the period of time that is above the threshold number of conflicts, and the first RSRP difference threshold is greater than the second RSRP difference threshold; or
(ii) the set of RSRQ thresholds comprises a first RSRQ threshold configured to be applied when a pair of SL transmissions is determined to be configured to result in the number of conflicts over the period of time that is above the threshold number of conflicts and the set of RSRQ thresholds comprises a second RSRQ threshold configured to be applied when the pair of SL transmissions is determined to not be configured to result in the number of conflicts over the period of time that is above the threshold number of conflicts.
