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.

Abstract
The disclosure provides an electronic device, a method and computer-readable medium. The electronic device includes a circuitry. The circuitry is configured to receive a radio communication signal for another device. The circuitry is also configured to determine, based on the radio communication signal, one or more features that can reflect the difference between uplink transmission mode and downlink transmission mode. The circuitry is further configured to judge whether the radio communication signal is for uplink transmission or downlink transmission according to the feature(s).
