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.
