1. An electronic device, comprising:

  • circuitry configured todetect one or more energy values of one or more samples on a channel in a spectrum unlicensed to the electronic device, each sample corresponding to a symbol in the channel;

    judge whether a predetermined relationship is satisfied between the detected energy values and a first threshold to determine an occupancy probability of the channel;

    send the occupancy probability of the channel to a serving base station, the serving base station deciding opportunistic utilization of the channel for communication; and

    perform communication based on the opportunistic utilization of the channel decided by the base station.
