Abstract: A method is provided for receiving aperiodic channel state information (CSI). A base station (BS) transmits, to a user equipment (UE), an uplink downlink control information (DCI) format. The BS receives, from the UE, aperiodic CSI through a physical uplink shared channel (PUSCH) if the BS triggers an aperiodic CSI report using a CSI request field included in the uplink DCI format. The CSI request field is either a 1-bit field or a multi-bit field. When the UE is configured with only one cell, the 1-bit field is included in the uplink DCI. When the UE is configured with more than one channel state information-reference signal (CSI-RS), the multi-bit field is included in the uplink DCI.

Abstract: A method is provided for receiving a downlink control channel in a wireless communication system. A user equipment performs a blind decoding in a first search space on the cell to find a first Physical Downlink Control Channel (PDCCH). The user equipment receives a Radio Resource Control (RRC) message including information on a second search space for monitoring a second PDCCH and identity information, and performs a blind decoding in the second search space on the cell to find the second PDCCH. The first PDCCH is demodulated based on a physical cell identity of the cell, and the second PDCCH is demodulated based on the identity information instead of the physical cell identity.
