Method and apparatus for controlling uplink transmission on discontinuous reception operation in wireless communication system
A method for controlling uplink transmissions on discontinuous reception (DRX) operation, by a wireless device, in a wireless communication system, the method includes configuring a channel quality indicator (CQI) masking which indicates that channel state information is to be reported on a physical uplink control channel (PUCCH) while an onDurationTimer is running; determining, at a first subframe prior to a second subframe, whether or not the onDurationTimer is to be running at the second subframe according to whether or not a physical downlink control channel (PDCCH) is received at the first subframe; and controlling the uplink transmissions so as not to report the channel state information on the PUCCH at the second subframe if the onDurationTimer is determined, at the first subframe, to be not running at the second subframe, wherein the channel state information includes at least one of a CQI, a precoding matrix index (PMI).
