Abstract
A method and apparatus for removing interference from a UpLink (UL) signal in a Time Division Duplex (TDD) system are provided. The method includes determining whether a section for receiving an UpLink (UL) signal from the MS overlaps with sections for sending a DownLink (DL) signal of neighbor BSs in service, the neighbor BSs sending the DL signal to another MS, when the UL signal section overlaps with the DL sections of the neighbor BSs, detecting DL transmit signal information from the neighbor BSs transmitting in the overlapping sections, and removing interference from the UL signal using the detected transmit signal information. Accordingly, the accuracy of detecting the signal from the MS can be raised without having to adopt the complex resource allocation scheme to avoid the interference of the neighbor BSs.
