BASE STATION DEVICE, USER DEVICE, AND METHOD IN MOBILE COMMUNICATION SYSTEM |
摘要 |
<p>A base station device is used in a mobile communication system of the MIMO method which performs precoding. The base station device includes: reception means which receives from a user device, a precoding matrix indicator (PMI) indicating a particular precoding vector; means for deciding a flag indicator value indicating whether to use the precoding vector specified by the PMI for downlink communication; control signal generation means for generating a downstream control signal in accordance with the flag indicator value; and means for transmitting signals including the downstream control signal by a downlink.</p> |
