摘要： A system and method for reporting quantized feedback information for adaptive codebooks include generating channel state information, encoding all or part of the channel state information to produce a feedback payload and transmitting the feedback payload to a base station from a mobile station. The channel state information comprises a rank indicator, a first matrix indicator, a wideband channel quality indicator, a second matrix indicator and at least one narrowband channel quality indicator. When the rank indicator is greater than 1, the first matrix indicator is reported in a second report. On the other hand, when the rank indicator is equal to 1, the content of the first matrix indicator is split between a second report and a third report.
