SIDELINK COMMUNICATION USING FIXED FRAME PERIODS

Abstract

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured with a timing of a frame structure for sidelink communications via a shared channel. The timing of the frame structure may correspond to a fixed frame period (FFP), and the first UE may initiate sidelink communications at the boundaries of the FFPs. The first UE may also support techniques for determining whether to initiate a channel access procedure to occupy a shared channel during a first FFP. In one example, the first UE may determine whether to initiate the channel access procedure to occupy the shared channel during the first FFP based on monitoring the shared channel during a second FFP for a sidelink transmission from a second UE. In another example, the first UE may receive an indication of whether to initiate the channel access procedure during the first FFP.
