Abstract: A wireless communication system, an apparatus, and a method in a wireless communication system. The apparatus includes a processing circuit. The processing circuit is configured to: detect whether a pre-set power margin reporting trigger event is satisfied; and trigger, if the pre-set power margin reporting trigger event is satisfied, reporting of a power margin of a user equipment to a base station, wherein the pre-set power margin reporting trigger event includes at least one of the following events: a first event of having detected an idle channel on an unlicensed band; and a second event of having received uplink scheduling licensed signalling from the base station. A power margin in an LAA system can be effectively reported.

Abstract: Disclosed are an electronic device in a wireless communication system, and a wireless communication method. The wireless communication system comprises multiple unlicensed carriers. The electronic device comprises: one or more processing circuits configured to: configure each of a plurality of unlicensed carriers to be a primary channel or a secondary channel, so as to obtain at least two primary channels and at least one secondary channel; perform a first channel detection process over each of the primary channels to detect whether each of the primary channels is idle, and perform a second channel detection process over each of the secondary channels to detect whether each of the secondary channels is idle; and perform downlink data transmission over the primary channel determined to be idle by means of the channel detection or over the primary and secondary channels determined to be idle by means of the channel detection. By utilizing the electronic device and the wireless communication method, the probability of access to an unlicensed carrier is improved.
