Abstract
The present invention provided a method and apparatus for reporting a channel quality in a wireless communication system. A terminal receives an uplink grant from a base station via one of a plurality of downlink component carriers (CCs). The uplink grant includes a channel quality indicator (CQI) request for instructing uplink allocation and CQI reporting. The terminal reports the CQI of the downlink CC being linked to the base station. The downlink CC being linked is one of the plurality of downlink CCs, which is linked to the uplink CC for which the uplink allocation is scheduled.
Claims15
A method for reporting channel quality in a wireless communication system, the method comprising:
- receiving an uplink grant from a base station through one of a plurality of downlink component carriers (CCs), the uplink grant including an uplink allocation and a channel quality indicator (CQI) indicating a triggering of CQI reporting;
- and
- reporting a CQI of a linked downlink CC to the base station,
- wherein the linked downlink CC is a downlink CC linked to an uplink CC in which the uplink allocation is scheduled among the plurality of downlink CCs.
An apparatus configured for reporting channel quality in a wireless communication system, the apparatus comprising:
- a radio frequency (RF) unit configured for transmitting and receiving a radio signal;
- and
- a processor coupled to the RF unit and configured for:
- receiving an uplink grant from a base station through one of a plurality of downlink component carriers (CCs), the uplink grant including an uplink allocation and a channel quality indicator (CQI) indicating a triggering of CQI reporting;
- and
- reporting a CQI of a linked downlink CC to the base station,
- wherein the linked downlink CC is a downlink CC linked to an uplink Cc in which the uplink allocation is scheduled among the plurality of downlink CCs.
