The invention provides a multi-input multi-output (MU-MIMO) user pairing method and device, relates to the technical field of communication, and is used for solving the problem that every two users in a cell need to be paired through a pairing algorithm in MU-MIMO user pairing at present, and the calculated amount is large. The method comprises the following steps: acquiring service information of each first to-be-paired user in a target cell to obtain service information of a plurality of first to-be-paired users; one piece of service information is used for reflecting the current service type of one first to-be-paired user; obtaining a preset service type, and determining a plurality of second to-be-paired users from the plurality of first to-be-paired users according to the preset service type and the service information of each first to-be-paired user; the second to-be-paired user is a user of which the current service type is different from the preset service type; and performing MU-MIMO pairing on the p
