Abstract:
A device and method for use in a MIMO wireless communication system are provided. The device used in the MIMO wireless communication system includes a matching unit configured to determine a matching degree of channel estimation information of a communication device to be scheduled with one or more reference vectors included in a reference vector group, where the reference vector group depends on an antenna array configuration of the MIMO wireless communication system; and a channel characteristic determining unit configured to determine correlation information of the one or more reference vectors with the matching degree satisfying a predetermined condition as one or more parameters reflecting channel characteristic(s) associated with the communication device. By applying the device and method according to the disclosure, it is possible to avoid interference among strong-space-correlated users, and thereby improve the efficiency of processing such as scheduling, noise reduction and so on.

Claim (Index 17):
A communication device for use in a wireless communication system, comprising:\n circuitry configured to\n receive a reference signal from a base station to determine a channel between the communication device and the base station; \n determine a matching degree of the channel with one or more reference directions based on the reference signal; \n determine a reference direction satisfying a predetermined condition as a representative direction of the channel; \n determine one or more parameters reflecting channel characteristic(s) associated with the communication device, the one or more parameters including identity of the representative direction; and \n acquire scheduling information from the base station for data transmission through the channel on specific transmission resources, \n wherein Multi-User Multi-Input Multi-Output MU-MIMO is supported, the specific transmission resources are avoided to be scheduled to other communication device having identical representative direction.
