The present disclosure relates to a 5generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4generation (4G) communication system such as long-term evolution (LTE). The present disclosure relates to beam management in a wireless communication system, and an operation method of a base station may comprise the steps of: transmitting first type reference signals; receiving feedback information on the first type reference signals; transmitting information on resources for second type reference signals, which are allocated on the basis of the feedback information, to at least one terminal; and transmitting the second type reference signals through the resources, wherein the second type reference signals are transmitted using fixed transmission beams by the base station. The present research has been conducted with the support of the 'cross-departmental giga KOREA project' of the government (the ministry of science and ICT) in 2017 (No. GK17N0100, Development for mmWave-based 5G mobile communication system).

Device and method for beam management in wireless communication system

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.

Method and apparatus for transmitting control channel in wireless communication system

The present 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). According to various embodiments of the present disclosure, an apparatus of a base station of a wireless communication system may comprise at least one transceiver, and at least one processor operatively coupled to the at least one transceiver. The at least one processor is configured to transmit, to a terminal, a plurality of reference signals including a first plurality of reference signals corresponding to a first polarized wave and a second plurality of reference signals corresponding to a second polarized wave, and receive feedback information indicative of at least one reference signal of the plurality of reference signals, wherein the first plurality of reference signals respectively correspond to a plurality of beams, the second plurality of reference signals respectively correspond to the plurality of beams, and the second polarized wave may be orthogonal to the first polarized wave.
