US 11,910,434 B2 · Sidelink channel access timeline techniques for wireless communications systems

Abstract

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination thereof.

receiving control signaling indicating a configuration for performing channel sensing, the configuration comprising one or more parameters corresponding to a processing time associated with the channel sensing that occurs after a sensing window associated with the channel sensing and before a resource selection trigger;
adjusting the processing time associated with the channel sensing based at least in part on the one or more parameters and a full duplex capability of the first UE;
and
transmitting, to a second UE using a first set of resources, a sidelink message based at least in part on the adjusted processing time.
