METHOD AND DEVICE FOR CONTROLLING AND COOPERATING WITH TRANSMITTING DOWNLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM |
摘要 |
<p>A method and device for controlling the serving BS and at least one coordinating BS for coordinating downlink data communication with the MS in a wireless telecommunication network based on CO-MIMO technology. The method comprises obtaining the MIMO downlink channel information between the serving BS and the MS and between the coordinating BS and the MS, determining the downlink signal precoding information between the serving BS and the MS and between the coordinating BS and the MS according to the channel information, and performing MIMO downlink data communication coordinately with the MS based on the downlink signal precoding information.</p> |
