Patent number: 8565215Abstract: A method and a base station can be used for detecting an interfering base station. A second base station sends no second downlink synchronization code in a downlink pilot time slot DwPTS of a specified frame, so that the second base station receives a first downlink synchronization code in a downlink pilot time slot DwPTS of a first base station, and performs correlation calculation on a detecting code segment of uplink data of the second base station by using the first downlink synchronization code, and by judging whether a correlation value of one of detecting code segments in the uplink data is greater than a correlation value threshold, determines whether the second base station is an interfering base station of the first base station.Type: GrantFiled: December 12, 2012Date of Patent: October 22, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Cuihong Ren, Wutao Yang, Shaojun Xu
