Techniques for selecting a sidelink sensing mode based on duplex mode

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive control signaling indicating a configuration comprising one or more criterion for selecting a sensing mode from a plurality of sensing modes for a sidelink resource selection procedure, wherein the one or more criterion is based at least in part on a duplex mode configured for a sensing window for the sidelink resource selection procedure;
• select the sensing mode from the plurality of sensing modes based at least in part on the configuration and the duplex mode;
• determine an available set of sidelink resource candidates from a selection window based at least in part on the selected sensing mode;
• and
• transmit a sidelink message using one or more resources of the available set of sidelink resource candidates.

A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive control signaling indicating a configuration comprising one or more criterion for selecting a sensing mode from a plurality of sensing modes for a sidelink resource selection procedure, wherein the one or more criterion is based at least in part on a duplex mode configured for a sensing window for the sidelink resource selection procedure;
• select the sensing mode from the plurality of sensing modes based at least in part on the configuration and the duplex mode;
• determine an available set of sidelink resource candidates from a selection window based at least in part on the selected sensing mode;
• and
• transmit a sidelink message using one or more resources of the available set of sidelink resource candidates.
