Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a data rate higher than that of 4G communication systems such as LTE systems. A method for controlling a device having a plurality of radio frequency (RF) chains coupled to a plurality of antennas in a wireless communication system according to an embodiment of the present invention includes comparing a measured temperature of the device with a temperature threshold, controlling status of at least one of the RF chains according to a comparison result between the measured temperature and the temperature threshold, and transmitting a radio signal using at least one of the antennas that is connected to the at least one RF chain.

Abstract: The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to provide for supporting higher data rates beyond a 4th-Generation (4G) communication system. A method performed by a distributed unit (DU) in a wireless communication system is provided. The method includes transmitting one or more data streams of a message of a control plane or a user plane, which correspond to one or more layers, to a radio unit (RU) through a first fronthaul port, and transmitting a data stream corresponding to an access layer, which is the first layer used for connection of a cell among the one or more layers, to the RU through a second fronthaul port configured between the DU and the RU.

Abstract: The present disclosure relates to a method for controlling interference measurement by an interference measurement control device, the method comprising the steps of: calculating distance information between a transmission side transmitting a reference signal for interference measurement and a reception side receiving the reference signal; calculating, on the basis of the distance information, signal delay information related to a delay time required until the reference signal transmitted from the transmission side arrives at the reception side; and determining control information for the transmission side or the reception side on the basis of the signal delay information.
