User equipment (UE) may benefit from power management techniques, for example, in the context of cellular vehicle-to-everything (CV2X) communication. In various aspects of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to determine whether a first subframe includes at least one sub-channel carrying information intended for the UE, receive the information via at least one receive (Rx) chain associated with the at least one sub-channel when the information intended for the UE is carried on the at least one sub-channel included in the first subframe, and deactivate the at least one Rx chain associated with the at least one sub-channel based on whether the information intended for the UE is absent from the at least one sub-channel included in the first subframe.
