Method and device for cell interference management

Abstract

Provided in embodiments of the present invention are a method and device for managing cell interference. The method comprises: generating carrier coordination information, where the carrier coordination information comprises frequency information of a carrier and trans-carrier scheduling-related information of the carrier, and where the trans-carrier scheduling-related information is for use by a first base station and by a second base station in negotiating scheduling characteristics of the carrier, thus reducing on the carrier a co-channel interference between the first base station and the second base station; and transmitting the carrier coordination information to the second base station. The embodiments of the present invention allow for the exchange between base stations of the frequency information of the carrier used thereby and of the trans-carrier scheduling-related information of the carrier, thereby coordinating between the base stations in configuring different scheduling characteristics for a same carrier, thus reducing the co-interference between the base stations.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a method and device for cell interference management. Background technique [0002] With the introduction of CA (carrier aggregation, carrier aggregation) technology, a base station can work on multiple carriers at the same time. The carrier scheduled by the carrier is called a secondary carrier. The CA technology instructs the UE (User Equipment, user equipment) to obtain scheduling information from the PDSCH (Dedicated physical shared channel, physical downlink shared channel) of the secondary carrier through the PDCCH (Dedicated physical control channel, physical downlink control channel) of the main carrier, which further expands the capacity of the system. [0003] In a scenario where multiple carriers are deployed on an LTE (Long Term Evolution, Long Term Evolution) network, co-channel interference may exist between base stations. ...

AI Technical Summary

Problems solved by technology

[0005] However, the time-division-based solution requires two base stations to negotiate specific near-blank subframe positions. There are many signaling interactions between base stations, and the time synchronization accuracy requirements of base stations are also high, so co-channel interference cannot be effectively reduced.
