METHOD AND APPARATUS FOR CODEBOOK EXCHANGE IN MULTIPLE ACCESS WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for effectively and efficiently exchanging codebooks between an access network and an access terminal.

SOLUTION: A method comprises: providing a plurality of preferred precoding matrices; generating a codebook in an access network, in which the codebook comprises the plurality of preferred precoding matrices; and communicating the codebook to one or more access terminals. Communicating the codebook further comprises: querying the one or more access terminals to determine an identity of one or more codebooks currently stored in each access terminal; receiving a codebook status response from each of the one or more access terminals indicating the identity of one or more codebooks stored in each of the one or more access terminals; and communicating the codebook to one or more access terminals if the codebook status response indicates that the codebook is not currently stored in the one or more access terminals.
