Title:
CHANNEL ACCESS PRIORITIZATION FOR HIGH PRIORITY TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2023/082078
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit a sidelink message in accordance with one or more parameters associated with a priority of the sidelink message. The UE may determine a channel access priority class (CAPC) associated with the sidelink message based on the priority of the sidelink message. The UE may perform a listen-before-talk (LBT) procedure in accordance with the CAPC to gain access to a wireless channel for a channel occupancy time (COT). The UE may select a set of starting positions relative to the COT based on the priority, the CAPC, or both. The UE may transmit the sidelink message within the COT based on a starting position of the set of starting positions and the LBT procedure. The UE may perform a quantity of one or more retransmissions of the sidelink message based on the CAPC.
