Channel occupancy time (cot) sharing request in sidelink

Abstract

This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for sidelink channel occupancy time (COT) sharing request signaling in a wireless communication system. A sidelink transmitting user equipment (UE) transmits a COT sharing request to a sidelink initiator UE. The COT sharing request indicates to the initiator UE to initiate sharing of a COT acquired by the initiator UE with the transmitting UE. The initiator UE, in response to receiving the COT sharing request, determines to acquire the COT, and initiates COT sharing by transmitting, to the transmitting UE, COT sharing information including information to facilitate access to the COT by the transmitting UE. The transmitting UE, based on the COT sharing information received from the initiator UE, access the sidelink channel during the COT and transmits data over the sidelink channel.
