Abstract  Abstract

ABSTRACT A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/received unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQl feedback period based on 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 based on the uplink and downlink transmissions needs and sends a command to the WTRU to change the CQl feedback period of the WTRU. A WTfRU MONITORS A STATUS OF 102 DOWNLINK TRANSMiSSIONS TO THE WTRU. THE WTRU SETS THE CQt FEEDBACK PERIOD BASED ON THE STATUS OF DOWNUNK TRANSMISSIONS TO THE WTRU FIG.1 (START 20 S20202 A BASE STATION MONITORS UPLINK TRANSMISSION NEEDS AND DOWNUNK TRANSMISSION NEEDS. Is fr 204 DESIRABLE TO CHANGE THE CQl FEEDBACK PERIOD OF AT LEAST ONE . NO WTRU BASED ON THE UPLINK TRANSMISSION NEEDS AND THE DOWNUINK TRANSMISSION NEEDS? YES THEBAE TAION SENDS A COMMAND TO THE WVTRUJ 206 TO CHANGE THE CQI FEEDBACK PERIOD OF THE WTRU. RIG. 2
