Title: METHOD FOR COORDINATING INTER-MULTI-USER INTERFERENCE, AND BASE STATION
Abstract:
Disclosed are a method for coordinating inter-multi-user interference, and a base station, which are applied to an MU-MIMO system after antenna grouping and user grouping. The base station uses a CSI fed back by a plurality of user equipments to perform channel reconstruction and MU-MIMO weight value calculation so as to coordinate interference among a plurality of users, such that the problem of interference among the plurality of users can be effectively solved. The method for coordinating inter-multi-user interference in the embodiments of the present invention is applied to an MU-MIMO system. The MU-MIMO system includes at least two base station antenna groups and at least two user equipments, each of the user equipments corresponding to a base station antenna group. The method comprises receiving a CSI of each base station antenna group sent by each user equipment; performing channel reconstruction according to the CSI so as to obtain a channel matrix; obtaining an MU-MIMO weight value of each user equipment according to the channel matrix; and sending a user signal in a base station antenna group corresponding to each user equipment according to the MU-MIMO weight value.
