METHOD AND APPARATUS FOR ADJUSTING CHANNEL QUALITY INDICATOR FEEDBACK PERIOD TO INCREASE UPLINK CAPACITY

摘要

PROBLEM TO BE SOLVED: To disclose a method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system.SOLUTION: The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period on the basis of the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU on the basis of the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.
