DOWNLINK TRANSMISSION IN A MU-MIMO SYSTEM

摘要

A method is provided for managing a downlink transmission in a Multi User-Multiple Input Multiple Output (MU-MIMO) system. The MU-MIMO system includes a base station and a set of remote radio units connected to the base station. The method includes: obtaining large scale fading data related to a large scale fading over uplink transmission associated with a user equipment (UE); generating a UE-specific channel vector by using the large scale fading data; and scheduling a downlink transmission by using the UE-specific channel vector.

1. Method for managing a downlink transmission in a Multi User-Multiple Input Multiple Output MU-MIMO system, the MU-MIMO system comprising a base station (1), and a set of remote radio units (2a-2c) connected to the base station, the method comprising steps of:
/1/ obtaining large scale fading data related to a large scale fading over uplink transmission associated with a user equipment (4a-4d), /2/ generating a UE-specific channel vector by using the large scale fading data, and /3/ scheduling a downlink transmission by using the UE-specific channel vector.
