METHOD AND EQUIPMENT FOR CONTROLLING CO-CHANNEL INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and equipment for controlling co-channel interference in BS (Base Station) of wireless communication system based on collaboration MIMO technology, and the corresponding method and equipment for controlling co-channel interference used in assistant BS in mobile terminal of wireless communication network based on collaboration MIMO technology are provided in the present invention. Because codebook-based on feedback mechanism is applied in the collaboration MIMO system of the present invention, the present invention could be applied in both Time-division duplex mode and Frequency-division duplex mode. And additionally, because the pre-coding vectors selected by different mobile terminals are always orthogonal, the co-channel interference of multi-user could be reduced.
