Abstract
A method for pairing user terminals in the MU-MIMO system comprises: a base station sets pairing parameters; the base station receives report information of a user terminal, and sets parameter identifiers according to the set pairing parameters and the report information; and after determining that the user terminal which reported the report information is a user terminal to be paired, the base station determines a user terminal paired with the user terminal to be paired according to the set parameter identifiers. A device for pairing user terminals in the MU-MIMO system comprises a parameter setting unit, a parameter identifier setting unit and a pairing performing unit. Under the precondition of considering the path loss condition of the user terminals, the present invention combines with the path condition of the user terminals to pair the user terminals, which can relieve the influences of the interference on the pairing result to a certain extent, and improve the performance of the MU-MIMO system.
