Abstract: The present invention relates to 5G or pre-5G communication system for supporting a higher data transmission rate after 4G communication system such as LTE. The present invention provides a carrier aggregation method. A method of a base station, according to the present invention, comprises a step for: transmitting and receiving data to and from a terminal by means of a first carrier corresponding to a first bandwidth; transmitting to the terminal, by means of the first carrier, configuration information comprising information for an initial access to a second carrier corresponding to a second bandwidth; and transmitting and receiving data to and from the terminal by means of the second carrier on the basis of the configuration information.

Abstract: Disclosed are a method and an apparatus for channel quality estimation in consideration of interference control and coordinated communication in a cellular system. A base station receives an SRS transmitted by a terminal to thus measure received power, and then configures, for the terminal, a CSI process which may measure SINRs for base stations having higher SRS received power. If the terminal feeds back, to the base station, channel quality information for the configured CSI process, the base station determines an SINR and a MCS to be applied to data transmission in consideration of a received CQI and a CoMP transmission scheme, and applies the determined SINR and MCS to thus transmit data.

Abstract: A method performed by a user equipment (UE) in a wireless communication system includes transmitting a UE capability information message to a base station, the UE capability information message including information for indicating that a multi-beam operation for multi-transmission and reception point (TRP) is supported and information for indicating that a simultaneous reception for different beams is supported, receiving a first control signal for first data on a first physical downlink control channel (PDCCH) associated with a first TRP, the first control signal transmitted by using a primary beam, and receiving second control signal for second data on a second PDCCH associated with a second TRP, the second control signal transmitted by using a secondary beam. The first data and the second data are received in same time resources.

Abstract: Provided are a method and a Base Station (BS) for transmitting a control channel and a method and a User Equipment (UE) for receiving a control channel in a wireless communication system. The BS includes: a transceiver; and at least one processor configured to control the transceiver to receive Beam State Information (BSI) from the UE through at least one first beam, identify a second beam, based on the BSI, and control the transceiver to transmit a first BSI request to the UE through the second beam, identify a third beam, based on information on the at least one first beam, and determine whether control the transceiver to transmit the control channel to the UE through the third beam.
