METHOD AND APPARATUS FOR OPTIMIZING A LIMITED FEEDBACK IN A WIRELESS ACCESS SYSTEM SUPPORTING A DISTRIBUTED ANTENNA DA TECHNICUE

摘要

The present invention relates to wireless access systems, and more particularly to methods and apparatus for optimizing limited feedback in distributed antenna systems (DASs). A method for optimizing limited feedback in a wireless access system that supports distributed antenna (DA) technology as an aspect of the present invention includes receiving information related to transmission power of DA ports from a DA port, Measuring a distance between the terminal and the DA ports using the downlink signals, calculating the number of feedback bits based on the information related to the transmission power and the distance between the terminal and the DA ports, And transmitting the feedback information using the calculated number of feedback bits.;
