Abstract

The invention relates to a user grouping method, a device, a base station and a storage medium of space division multiple access. The user grouping method of SDMA comprises the following steps: receiving detection reference signals reported by at least two different user terminals; obtaining a channel estimation value of a channel in which the user terminal is located according to the detection reference signal; Calculating a correlation value representing a correlation between two different user terminals transmitting the detection reference signal according to the obtained channel estimationvalue; it is judged whether the data sent by the two different user terminals participating in the calculation is spatially multiplexed according to the calculated correlation value. The invention carries out space division multiplexing according to the correlation between different user terminals, and carries out space division multiplexing on the data sent by the user terminals with little correlation, so the the base station does not cause decoding error after space division multiplexing because the user terminals select orthogonal codes the interfere with each other, and the effective uplink flow in determining the bandwidth resources is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a user grouping method, device, base station and storage medium of space division multiple access. Background technique [0002] At present, in the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) communication system of LTE (Long Term Evolution, Long Term Evolution), especially in the uplink channel, data sent by users with strong Division multiplexing, according to the protocol rules of 3GPP, these users will choose orthogonal codes that interfere with each other in space division multiplexing mode, such as "1" and "11". If the base station encounters such orthogonal codes when decoding, it is easy It leads to decoding errors, causing the user terminal to retransmit data, and the retransmitted data may also cause decoding errors again due to inappropriate space division multiplexing, resulting in a vicious circle, so that the decod...
