Abstract
Apparatus and methods are provided for a user equipment (UE) to control sidelink power allocation on multiple carriers. The UE determines, from a plurality of PSFCHs scheduled for simultaneous transmissions on the plurality of carriers, a prioritized PSFCH to be simultaneously transmitted across the plurality of carriers based at least in part on a maximum number of capabilities of the UE for simultaneous physical sidelink feedback channel (PSFCH) transmissions for each of the plurality of carriers and a total transmit power, PCMAX, of the UE, wherein j is an index of a jth carrier of the plurality of carriers. The UE determines an allocated transmit power for prioritizing the PSFCH. The UE then simultaneously transmits the prioritized PSFCH on the plurality of carriers according to the allocated transmission power.
