Abstract: Embodiments of the present disclosure provide a backoff window adjustment method, and an apparatus. In downlink transmission, a base station obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the base station on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel. In uplink transmission, a user equipment (UE) obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the UE on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel.

Abstract: The present invention discloses a wireless communication method and apparatus, where the method includes: receiving a configuration for an energy detection on a to-be-listened-on spectrum from a base station, wherein the to-be-listened-on spectrum belongs to an unlicensed spectrum, and the configuration comprises description information about the to-be-listened-on spectrum and a time parameter for performing the energy detection; performing an energy detection on the to-be-listened-on spectrum according to the configuration for the energy detection; and sending a report about the energy detection on the to-be-listened-on spectrum to the base station, wherein the report is used for an unlicensed spectrum selection. Therefore, the base station can select a suitable unlicensed spectrum to communicate with the UE, thereby reducing strength of possible interference caused to communication between the base station and the UE on the selected unlicensed spectrum.

Abstract translation: 本发明公开了一种无线通信方法和装置，其特征在于，该方法包括：从基站接收对待观看频谱上的能量检测结构，其中所述待收听频谱属于 未许可频谱，并且该配置包括关于待收听频谱的描述信息和用于执行能量检测的时间参数; 根据能量检测的结构，对待收听频谱进行能量检测; 并向基站发送关于待收听频谱上的能量检测的报告，其中所述报告用于未经许可的频谱选择。 因此，基站可以选择合适的未授权频谱与UE进行通信，从而降低在所选择的未许可频谱上对基站和UE之间的通信造成的可能干扰的强度。
