TECHNIQUES FOR USING PHYSICAL RESOURCE BLOCKS (PRBS) IN A SIDELINK RESOURCE POOL

Abstract:

Certain aspects of the present disclosure provide techniques for using physical resource blocks (PRBs) of a sidelink resource pool that, in some cases, might not belong to a sub-channel in sidelink or are assigned to a special sub-channel. When a user equipment (UE) is transmitting a sidelink communication, the sidelink communication often takes place in resource pools that include sub-channels in frequency domain and slots in a time domain. A first subset of PRBs of the resource pool may be assigned to one or more sub-channels in the frequency domain. The disclosed methods, devices, and systems provide for identifying PRBs not assigned to the first subset (e.g., remaining or unused PRBs or PRBs assigned to a special sub-channel). In some aspects of the present disclosure, the UE may use these PRBs for various purposes.
