METHOD AND APPARATUS FOR INTERFERENCE ALIGNMENT BASED FREQUENCE ASSIGNMENT

摘要

The present invention relates to a kind of distribution of frequency to be used for this purpose in interference channel and transmission device. The present invention is by following procedure: a kind of processing Base Transmitter pilot signal gives multiple terminals; Feedback information is received in base station, interferes ratio from above-mentioned multiple terminals channel signals; Sub-carrier number and terminal are determined in base station to apply interference alignment and use the feedback information; Exceeding preset frequency bands in the base station selected interference alignment by frequency band to be used and generate transmitting pre-encoding matrix utilizes maximum accessible freedom degree from each frequency; Pass through transmitting pre-encoding matrix with the index of the frequency band selection in Base Transmitter to terminal. ;The 2015 of copyright KIPO submissions
