A METHOD OF TRANSMITTING FEEDBACK INFORMATION IN A MULTI-INPUT, MULTI-OUTPUT (MIMO) SYSTEM

摘要

A method of transmitting feedback information in a Multi-Input, Multi-Output (MIMO) system is disclosed. In the method, a mobile station (MS) which determines to transmit feedback information and feedback type to a base station (BS) without solicitation from the BS, wherein the feedback type is transmission antenna type, and transmits the feedback information using a MIMO mode feedback extended subheader, wherein the MIMO mode feedback extended subheader appears between a Medium Access Channel (MAC) header and a payload.
