Title:
CHANNEL BUSY MEASUREMENTS FOR SIDELINK COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/232340
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a channel busy measurement for each listen-before-talk (LBT) subband of an unlicensed radio frequency spectrum band and determine whether to use the one or more LBT subbands for sidelink communications with another UE. The channel busy measurement may include a channel occupancy ratio (CR) measurement or a channel busy ratio (CBR). The UE may determine an availability of the LBT subband based on performing the measurements for each LBT subband. The UE may perform a scheduling operation for a sidelink message to another UE using the available LBT subbands. The UEs may communicate according to the scheduling operation.
