摘要： Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. According to an embodiment of the present invention, a method by which a base station transmits a signal in a wireless communication system comprises the steps of: transmitting, to a terminal through at least one beam, at least one beam index including information on beam direction; receiving, from the terminal, a preferred beam index determined by the terminal; determining a channel matrix between the base station and the terminal on the basis of the preferred beam index; and allowing the base station to transmit a signal to the terminal on the basis of the channel matrix. The study has been performed under the support of the “Government-wide Giga KOREA Business” of the Ministry of Science, ICT and Future Planning.

摘要： 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.

摘要： 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.

摘要： A signal transmission method and apparatus of a base station is provided for increasing transmit power by compensating a phase value of the signal transmitted through multiple antennas based on signal reception status information fed back from a terminal in a wireless communication system. The signal transmission method includes transmitting a signal to at least one terminal through the multiple antennas; receiving signal reception status information transmitted by the at least one terminal; calculating a compensation phase based on the signal reception status information; applying the compensation phase to next signal to be transmitted through the multiple antennas; and transmitting the next signal to the at least one terminal through the multiple antennas.
