1. A method, comprising:

  • operating a communication device according to a particular frequency hopping sequence in a communication network, the particular frequency hopping sequence having a plurality of timeslots each corresponding to a particular frequency within the frequency hopping sequence, each timeslot divided into a plurality of sub-timeslots; and

    operating the communication device in a first mode, wherein the first mode comprises;

    sampling the particular frequency hopping sequence by a receiver of the communication device during only a particular specified sub-timeslot of a timeslot;

    detecting whether a transmission energy is detected during the specified sub-timeslot;

    in response to detecting that there is no transmission energy during the specified sub-timeslot, turning off the receiver for a remainder of the timeslot; and

    is in response to detecting that there is transmission energy during the specified sub-timeslot, continuing to sample the particular frequency hopping sequence for at least one or more additional sub-timeslots of the remainder of the timeslot.
