Abstract

The invention discloses a user pairing processing method and device, and a base station. The method comprises the steps: receiving a signal which is transmitted by UE and used for generating a channel matrix H; generating the channel matrix H of the UE according to the received signal; generating a space division information table according to the generated channel matrix H, wherein the space division information table is used for identifying correlation among UE; and determining a paired user according to the generated space division information table. The method and device solve problems in related technologies that there is an interference error, the pairing capacity is small and the complexity is high when a user employs MU-MIMO for pairing. The method and device achieve the effects of simplifying the user pairing complexity and improving the capacity of an MU-MIMO 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, which doubles the capacity and spectrum utilization of the communication system without increasing the system bandwidth; The impact of multipath fading, and can effectively eliminate co-channel interference, improve the reliability of the channel, reduce the bit error rate, is the key technology adopted by the new generation of mobile communication systems. [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 users in the same...
