Abstract
A coordinated beamforming method and device. The method includes: upon receipt of coordination request from multiple coordinated multi-point user equipments (CoMP UE), determining a target CoMP UE from multiple CoMP UEs; calculating a channel correlation value between the target CoMP UE and each candidate coordinated UE in a coordinated cell; determining, on basis of channel correlation value between the target CoMP UE and each candidate coordinated UE, a target coordinated UE; if the channel correlation value between target coordinated UE and the target CoMP UE is lower than a preset lower channel correlation threshold, then not performing beamforming orthogonalization adjustment on the target coordinated UE; and if the channel correlation value between target coordinated UE and target CoMP UE is greater than or equal to the preset lower channel correlation threshold, then performing beamforming orthogonalization adjustment on target coordinated UE. The present application can greatly reduce the probability of a performance decline of the target coordinated UE.
