Sidelink candidate resource selection

An apparatus for wireless communications at a first 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:
• perform a power measurement associated with at least one neighboring UE during a time window for resource selection for transmission of a sidelink message from the first UE to a second UE;
• increase a size of the time window for selection of resources for transmission of the sidelink message based at least in part on the power measurement associated with the neighboring UE exceeding a stop power threshold;
• select resources for transmission of the sidelink message from a set of candidate resources within the time window with the increased size for transmission of the sidelink message, the set of candidate resources corresponding to a threshold percentage of total resources within the time window with the increased size being available for resource selection based at least in part on an initial power threshold,
• the stop power threshold, the power measurement associated with the at least one neighboring UE, and the increased size of the time window;
• and
• transmit the sidelink message to the second UE via the selected resources.

An apparatus for wireless communications at a network node, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish a communication link with a first user equipment (UE) in communication with a second UE via a sidelink communications link;
• and
• transmit, to the first UE, an indication of a configuration for candidate resource selection for a sidelink message from the first UE to the second UE, the configuration based at least in part on an initial power threshold and a stop power threshold, wherein the stop power threshold is associated with increasing a size of a time window for candidate resource selection for the sidelink message at the first UE based at least in part on a power measurement associated with the second UE exceeding the stop power threshold.
