FEEDBACK SCHEDULING TO REDUCE FEEDBACK RATES IN MIMO SYSTEMS

摘要

closed loop wireless communication system 200 in the reception device are unnecessary precoding so as not to feed back the information to the transmitting apparatus 302, a plurality of receivers in order to control the feedback (304.1 - 304.3) is a codebook-based feedback feedback scheduling (201.1) from the control mechanism is provided, respectively. Give each receiver by establishing and distributing the schedule 310 for controlling the time of feeding back the precoding information (201.1), or the feedback metric based feedback threshold that must be met before being allowed (704, 706) can be established and controlled by the distribution.
