Abstract

The embodiments of disclosure disclose a method and device for processing user pairing, and a base station. The method includes that: a signal reported by a User Equipment (UE) for generating a channel matrix H is received; the channel matrix H of the UE is generated according to the received signal; a space division information table for identifying correlation between UEs is generated according to the generated channel matrix H; and paired users are determined according to the generated space division information table. The disclosure solves problems of interference error, low pairing capacity and high complexity when the user pairing is performed by using Multiple User-Multiple Input Multiple Output (MU-MIMO) in the related art, thereby simplifying the user pairing and improving MU-MIMO system capacity.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a user pairing processing method, device and base station. Background technique [0002] Multiple User-Multiple Input Multiple Output (Multiple User-Multiple Input Multiple Output, referred to as MU-MIMO) is a space diversity technology that doubles the capacity and spectrum utilization of the communication system without increasing the system bandwidth; Utilizing diversity to reduce the influence of multipath fading, and can effectively eliminate co-channel interference, improve channel reliability, and reduce bit error rate is the key technology adopted by the new generation mobile communication system. [0003] MU-MIMO is a method and technology that allows multiple users to use the same time-frequency resources, thereby further improving system capacity. Since MU-MIMO users need to space-divide resources in the time-frequency domain, if the spatial orthogonality between us...
