METHOD AND APPARATUS FOR UPLINK TRANSMISSIONS AND CQI REPORTS WITH CARRIER AGGREGATION

摘要

PURPOSE: A method and device for an uplink transmission and a CQI report with carrier aggregation technique are provided to enable a subscriber station to transmit an ACK or NACK to the base station. CONSTITUTION: An RR(Radio Frequency) transceiver(1410) communicates with a base station through at least one uplink element carrier wave and a plurality of downlink element carrier waves. The RF transceiver transmits at least one periodical PUCCH(Physical Uplink Control Channel) CQI report about a downlink element carrier wave from at least one uplink element carrier wave. Periods for reporting at least on PUCCH CQI report is as same as all uplink element carrier waves. A first PUCCH CQI about the first downlink element carrier wave is transmitted through the first uplink element carrier wave.
