Uplink mu-mimo operation parameter determination method and apparatus

Abstract

The application provides an uplink MU-MIMO working parameter determination method and device, and relates to the technical field of wireless communication, and the method comprises the following steps: acquiring current incidence angle data of surrounding AP signals arriving at the self; determining a target spatial mapping matrix and a target uplink channel communication capacity by using a trained spatial mapping matrix prediction model according to the current incidence angle data; determining a target uplink transmission power by using a trained transmission power prediction model according to the target uplink channel communication capacity and current signal bandwidth and a current modulation and coding indication; and determining the target spatial mapping matrix and the target uplink transmission power as target working parameters of uplink MU-MIMO. In this way, the working parameters of uplink MU-MIMO are predicted by using a spatial mapping matrix prediction model and a transmission power prediction model, multiple beam scanning searches and multiple rounds of working parameter iteration processes are saved, service establishment time is shortened, and network service quality is improved.
