Abstract

Disclosed are a user scheduling method and apparatus. The method comprises: network equipment determining a user equipment pair performing MU-MIMO (Multi-User Multiple Input Multiple Output) scheduling, the user equipment pair comprising first user equipment and second user equipment; the network equipment respectively instructing the two user equipment in the user equipment pair to perform port detection; for at least one user equipment in the user equipment pair, the network equipment sending a corresponding reference signal and traffic channel only on a part of ports detected under the instruction of the network equipment, so that the port for the network equipment to send the reference signal and the traffic channel to the first user equipment differs from the port for the network equipment to send the reference signal and the traffic channel to the second user equipment. The present invention can address the problem that owing to a wide difference between the performances of reception and processing at the user equipment side during MU-MIMO scheduling, inconsistent interference suppression capabilities lead to poor paired transmission performance of a plurality of users at the user equipment side.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a user scheduling method and device. Background technique [0002] The time-frequency domain positions of the reference signals of port7 (port 7) and port8 (port 8) in the LTE (Long Term Evolution) system are as follows: figure 1 As shown, the time-frequency positions of port7 / 8 / 11 / 13 and port9 / 10 / 12 / 14 are different, and the four pilot sequences of port7 / 8 / 11 / 13 are passed through orthogonal sequences (Walsh matrix) realizes the orthogonalization of time-frequency sequences and multiplexing of time-frequency resources, and port9 / 10 / 12 / 14 also adopts the same multiplexing method. [0003] MU-MIMO (Multi-User Multiple Input Multiple Output, multi-user-multiple input multiple output) means that in one scheduling time unit (Transmission Time Interval, TTI), make full use of the spatial independence of the channel and use the same time-frequency resources Multiple UEs ...
