Method and apparatus for periodic and polled channel quality feedback

A mobile station comprising:

• a receiver configured to receive information indicating subchannels for transmission of channel quality indices (CQIs), in a communication system having an uplink bandwidth divided into subchannels and a time domain having frames divided into time intervals, each time interval having a plurality of orthogonal frequency division multiplexing (OFDM) symbols;
• a transmitter configured to periodically transmit CQIs, based on a time interval number and based on the information indicating the subchannels;
• the receiver further configured to receive a poll for the mobile station to transmit a CQI;
• the transmitter further configured to transmit a CQI, based on the poll;
• the receiver further configured to receive a first OFDM signal derived from a first packet having a header portion, wherein the first packet includes a plurality of second packets, wherein each of the plurality of second packets has a header portion;
• and
• the receiver further configured to receive a second OFDM signal derived from a first segmented signal and a second segmented signal, transmitted in different time intervals, wherein the first segmented signal includes a first segment with a first attached header and the second segmented signal includes a second segment with a second attached header, wherein the first segment is a segment of a third packet and the second segment is a different segment of the third packet;
• wherein the third packet is reassembled using the first segment and the second segment.

A base station comprising:
