Abstract  Abstract

A method for detecting an uplink signal includes: detecting by a micro base station according to configuration information about an uplink signal sent by a UE whether the uplink signal is received in an uplink receive window of a macro base station where the macro base station and the micro base station have synchronized clock rates there is a fixed time difference t1 between the uplink receive window of the macro base station and an uplink receive window of the micro base station and ,t1,?0; and if it is detected that the uplink signal is not received in the uplink receive window of the macro base station after the micro base station advances the uplink receive window of the macro base station by a length of at least one cyclic prefix again detecting by the micro base station the uplink signal and sending the uplink signal to the macro base station. In the embodiments of the present invention an uplink signal of a UE can be effectively detected including a UE served by a macro base station and located outside a downlink coverage area of a micro base station and at an edge of the downlink coverage area of the micro base station.
