Abstract:
1. A method for aperiodically transmitting channel state information (CSI) by a terminal, the method comprising: receiving an indicator requesting a channel state information report of a downlink channel from a base station over a downlink control channel; and aperiodically transmitting the channel state information (CSI) to the base station over a physical uplink shared channel (PUSCH) in subframe n+k, upon receiving the indicator from the base station in subframe n, wherein k is a predetermined number of subframes, wherein a Cyclic Redundancy Check (CRC) is attached to a transmission control signal including the channel state information (CSI), in order to detect a CRC error from the transmission control signal, such that the transmission control signal including the CRC is transferred over the PUSCH.
