Method and apparatus for removing co-frequency interference

摘要

Provided are a method and device for eliminating co-frequency interference. The method comprises: a base station acquiring a transmission delay between a plurality of base stations adjacent to the base station; the base station receiving a reference signal reception power (RSRP) of a co-frequency adjacent cell reported by a service UE in a current cell; the base station determining, from the co-frequency adjacent cells having an RSRP correspondence in the current cell, a co-frequency adjacent cell, of which the transmission delay is greater than a pre-set threshold, as a candidate adjacent cell; and the base station configuring semi-persistent scheduling (SPS) information configured for the service UE as coordinated multi-point transmission or sending CoMP information, and transmitting same to the candidate adjacent cell, wherein the SPS information is used to indicate that the candidate adjacent cell periodically stops scheduling on a specified resource. The present invention solves the problem in the related art of the absence of how to use the CoMP technology to eliminate the downlink co-frequency interference in the existing network having a large transmission delay, and achieves the effect of improving the throughput of the user and the whole network spectrum utilization.
