determining timing of a CQI request based on information from a subscriber station;
requesting an Automatic Repeat reQuest ACKnowledgement (ARQ-ACK) message of downlink data and the CQI from the subscriber station at the determined timing;
allocating a radio resource for a report of the CQI to the subscriber station;
allocating a radio resource for the ARQ-ACK message to the subscriber station;
receiving the ARQ-ACK message and the CQI from the subscriber station; and
determining a modulation and coding level of downlink data based on the CQI.', 'determining timing of a CQI request based on information from a subscriber station;', 'requesting an Automatic Repeat reQuest ACKnowledgement (ARQ-ACK) message of downlink data and the CQI from the subscriber station at the determined timing;', 'allocating a radio resource for a report of the CQI to the subscriber station;', 'allocating a radio resource for the ARQ-ACK message to the subscriber station;', 'receiving the ARQ-ACK message and the CQI from the subscriber station; and', 'determining a modulation and coding level of downlink data based on the CQI.

9. The method of claim 8, wherein the informaion on the CINR includes a mean value or standard deviation of the CINR

10. An apparatus for requesting Channel Quality Information (CQI), the apparatus comprising:
a MAC layer configured to determine timing of a CQI request based on information from a subscriber station, allocate a radio resource for a report of the CQI to the subscriber station, allocate a radio resource for an Automatic Repeat reQuest ACKnowledgement (ARQ-ACK) message to the subscriber station, and determine a modulation and coding level of downlink data based on the CQI received from the subscriber station; and
a PHY layer configured to request the ARQ-ACK message of downlink data and the CQI from the subscriber station at the determined timing, and receive the ARQ-ACK message and the CQI from the subscriber station.', 'a MAC layer configured to determine timing of a CQI request based on information from a subscriber station, allocate a radio resource for a report of the CQI to the subscriber station, allocate a radio resource for an Automatic Repeat reQuest ACKnowledgement (ARQ-ACK) message to the subscriber station, and determine a modulation and coding level of downlink data based on the CQI received from the subscriber station; and', 'a PHY layer configured to request the ARQ-ACK message of downlink data and the CQI from the subscriber station at the determined timing, and receive the ARQ-ACK message and the CQI from the subscriber station

11. The apparatus of claim 10, wherein the radio resource for the report of the CQI and the radio resource for the ARQ-ACK message are allocated by using a same channel

12. The apparatus of claim 10, wherein the information from the subscriber station includes informaion on a Carrier to Interference Noise Ratio (CINR) of a downlink that is previously received from the subscriber station

13. The apparatus of claim 12, wherein the informaion on the CINR includes a mean value or standard deviation of the CINR.']
