Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to an embodiment of the present invention, a method for controlling a base station supporting a multi-antenna system may comprise the steps of: generating a plurality of test signals for a plurality of antennas in a modem; controlling the plurality of generated test signals to be fed back to the modem through a plurality of feedback paths which are formed for the plurality of antennas, respectively, and do not affect each other; and identifying the plurality of test signals fed back to the modem, on the basis of the plurality of generated test signals.

Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The method includes identifying whether a channel forecast value is valid, the channel forecast value being acquired based on applying a learning algorithm to an input comprising channel values estimated based on first reference signals (RSs) received from a base station, transmitting, to the base station, an RS request message for requesting an update of the learning algorithm, based on the determining that the channel forecast value is invalid, receiving, from the base station, second RSs of an RS density determined based on the RS request message, generating an updated learning algorithm based on channel values estimated from the second RSs, and transmitting channel forecast information acquired based on the updated learning algorithm to the base station.

Abstract: A method and apparatus for feedback in a mobile communication system are provided. The method of feedback transmission for a user equipment (UE) in a wireless communication system includes receiving control information indicating whether a subframe of an uplink band is allocated for a downlink from a base station (BS), receiving data from the BS in at least three subframes according to the control information, and sending the BS feedback for the data received in the at least three subframes using transmission time interval (TTI) bundling.
