Abstract:
1. A wireless transmit/receive unit (WTRU) comprising: at least one processor configured to receive an orthogonal division multiple access (OFDM) signal; wherein the OFDM signal includes a plurality of subcarriers; wherein the at least one processor is configured to perform a quality measurement for each of a plurality of groups of the subcarriers; wherein the at least one processor is configured to determine a first value associated with a channel quality indicator (CQI) table; wherein the first value indicates a data rate; wherein differences between data rates in the CQI table are not uniform; wherein the at least one processor is configured to determine for each of the plurality of groups, an n-bit indication of an amount of difference in the channel quality indicator (CQI) table between the first value and a value associated with that group in response to the quality measurement of that group; wherein the at least one processor is further configured to transmit the n-bit indications.
