In some aspects, the UE 120-1 may identify or select the channel sensing mode from the one or more channels sensing modes based at least in part on one or more power constraint parameters. The one or more power constraint parameters may include a battery level parameter, a power source parameter (e.g., indicating a source of power for the UE 120-1, such as power from a battery power supply, an external power supply, and/or an alternating current (AC) power supply, among other examples), a power draw parameter, and/or a thermal constraint parameter, among other examples. The UE 120-1 may determine a value associated with one or more power constraint parameters. The UE 120-1 may identify or select the channel sensing mode, from the one or more channel sensing modes, based at least in part on the value associated with the one or more power constraint parameters. For example, if the value associated with the one or more power constraint parameters indicates that the UE 120-1 has lower power, has a power supply from an unreliable or limited power source (such as a battery power supply), is experiencing a high power draw, and/or is experiencing high thermal temperatures, then the UE 120-1 may identify that the UE 120-1 is to operate in the random selection mode (e.g., to conserve power and/or reduce a thermal temperature of the UE 120). If the value associated with the one or more power constraint parameters indicates that the UE 120-1 has higher power, has a power supply from a reliable power source (such as an AC power supply), is experiencing a low power draw, and/or is experiencing low thermal temperatures, then the UE 120-1 may identify that the UE 120-1 is to operate in the on-demand channel sensing mode or the full channel sensing mode.
