METHOD AND DEVICE FOR CONTROLLING THE COORDINATED TRANSMISSION FOR DOWNLINK SIGNALS IN A WIRELESS TELECOMMUNICATION NETWORK

摘要

Cooperation in a wireless communication system adopting the MIMO technology is a method and apparatus for controlling the cooperation and downlink data communications to the user terminal from the main base station and one or more cooperative base station is disclosed. The method comprising: determining a pre-coding information in the downlink signal to the user terminal from the main base station and a cooperative base station in accordance with the steps of: obtaining a MIMO downlink channel information of the user terminal, and channel information from the main base station and a cooperative base station , and according to the pre-coding information in the downlink signal includes the step of performing comparably to the user terminal and MIMO downlink data communication. ;
