Abstract

The invention provides a multi-user MIMO scheduling method and equipment, and the method comprises the steps: determining the time domain priority ranking of to-be-scheduled UE in a time domain scheduling process; acquiring a frequency domain communication parameter of the to-be-scheduled UE; determining a frequency domain communication parameter set to which the to-be-scheduled UE belongs according to the frequency domain communication parameters of the to-be-scheduled UE; selecting the to-be-scheduled UE of which the frequency domain isolation meets the requirement, performing pairing according to the time domain priority sequence, and performing frequency domain scheduling on the successfully paired to-be-scheduled UE pairs. According to the method provided by the invention, the priority of some terminals is improved in the time domain scheduling to ensure that the users entering the frequency domain scheduling are isolated as much as possible in space, so that the method of the users entering the frequency domain scheduling is changed, the pairing probability of multiple users in the frequency domain is improved, and the cell throughput rate of multi-user MIMO is further improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-user MIMO scheduling method and equipment. Background technique [0002] In an NR (New Radio, new air interface) system, functions of a multi-user MIMO (Multiple-In Multiple-Out, multiple-input multiple-out) scheduler are divided into time-domain scheduling and frequency-domain scheduling. In time-domain scheduling, the base station prioritizes the users in the cell according to the data type in the terminal data buffer and the broadband CQI (Channel Quality Indicator, Channel Quality Indicator) reported by the terminal, and decides which users in the cell are scheduled. The selected users will enter frequency domain scheduling, perform subsequent multi-user pairing and resource allocation, and determine MCS (Modulation and Coding Scheme, modulation and coding scheme) and TBS (Transport Block Set, transport block set) operations. [0003] In order ...
