Sidelink resource reevaluation

An apparatus for wireless communication at a wireless device, comprising:

• memory;
• and
• one or more processors coupled to the memory and configured to cause the wireless device to:
• perform a full reference signal receive power (RSRP) sweep for a first slot using a defined RSRP or a configured RSRP as an initial resource exclusion RSRP threshold and increment or decrement the initial resource exclusion RSRP threshold to determine a first resource exclusion RSRP threshold;
• select one or more sidelink candidate resources for a sidelink transmission based on the full RSRP sweep for the first slot;
• and
• perform a resource reevaluation for a second slot, the resource reevaluation for the second slot including one or more iterations of candidate resource consideration using the first resource exclusion RSRP threshold from the first slot as the initial resource exclusion RSRP threshold to determine a second resource exclusion RSRP threshold for resource selection in the second slot.

A method of wireless communication, comprising:

• performing a full reference signal receive power (RSRP) sweep for a first slot using a defined RSRP or a configured RSRP as an initial resource exclusion RSRP threshold and incrementing or decrementing the initial resource exclusion RSRP threshold to determine a first resource exclusion RSRP threshold;
• performing the full RSRP sweep for a second slot that is a number of slots following the first slot to determine a second resource exclusion RSRP threshold;
• and
• performing a resource reevaluation for each slot between the first slot and the second slot the resource reevaluation for each slot including one or more iterations of candidate resource consideration using the first resource exclusion RSRP threshold determined for the first slot as the initial resource exclusion RSRP threshold to determine an updated resource exclusion RSRP threshold for resource selection.

A non-transitory computer-readable medium storing computer executable code for wireless communication at a wireless device, the code when executed by one or more processors causes the wireless device to:

• perform a full reference signal receive power (RSRP) sweep for a first slot using a defined RSRP or a configured RSRP as an initial resource exclusion RSRP threshold and increment or decrement the initial resource exclusion RSRP threshold to determine a first resource exclusion RSRP threshold;
