Abstract

The invention relating to the technical field of wireless communication provides a user division method and device, thereby solving a problem that the complexity of user pairing in an existing 5G scene is relatively high and users in the cell need to be divided, but there is no scheme for user division at present. According to the embodiment of the invention, channel information of users in a cellis input into a clustering machine learning model; with the clustering machine learning model, the users are classified according to the motion characteristics of the users and the channel correlation. Therefore, channel interference among different types of users can be avoided during user pairing; for example, user pairing is carried out for near base station users or for far base station users, problems of near-far effect and the like are solved, repeated calculation time of multiple rounds of iteration or polling and the like is avoided, user pairing can be obtained relatively quickly, time delay is reduced, and the blank of 5G for user division schemes is filled.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for user division. Background technique [0002] Multi-user MIMO (Multiple Input Multiple Output, Multi Input Multi-Output) means that the base station sends multiple parallel data streams occupying the same time-frequency resources to different users or different users will occupy multiple parallel data streams occupying the same time-frequency resources. The data flow is sent to the system structure of the base station, and a group of qualified users is selected to form it. [0003] Since the performance of a multi-user MIMO system is inevitably limited by inter-user interference, choosing an appropriate user pairing can reduce the interference between users and improve the spectral efficiency of a multi-user MIMO system, and give full play to the space diversity effect to deal with wireless propagation. Unfavorable factors such as distance a...
