1. An integrated circuit for controlling a communication apparatus, the integrated circuit comprising:
receiving circuitry which, in operation, receives configuration information for transmitting, in subframe N in an uplink, at least one of a channel quality information report and a sounding reference symbol, and receives a media access control (MAC) control element regarding a discontinuous reception (DRX) operation,
control circuitry which, in operation, determines whether the communication apparatus will be in DRX Active Time or DRX Non-Active Time in subframe N, based at least on the MAC control element received until and including subframe N−(4+k), where k is an integer value equal to or greater than 1, and
transmitting circuitry which, in operation, does not transmit the channel quality information report or the sounding reference symbol in subframe N, in case the communication apparatus is determined to be not in DRX Active Time in subframe N.
