    Abstract: A communication method and a system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with an internet of things (IoT) technology are provided, which 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. A method and an apparatus for transmitting a reference signal are provided. The method includes receiving, from a base station, a first parameter and a second parameter associated with a sound reference signal (SRS) by higher layer signaling, identifying a bandwidth for the SRS based on the first parameter and the second parameter, and transmitting, to the base station, the SRS based on the identified bandwidth for the SRS.

    Abstract: 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). A method for beam management of a base station and an apparatus therefor are provided. The method includes receiving information on whether beam correspondence (BC) of a terminal is established, identifying information on whether BC of the base station is established, determining whether reciprocal BC is established based on the information on whether the BC of the terminal is established and whether the BC of the base station is established, and determining whether to perform an uplink beam management operation based on whether the reciprocal BC is established, and a base station for performing the same.

    Abstract: The present disclosure relates to a 5th-generation (5G) or pre-5G communication system, which is to be provided for supporting higher data transmission rates after a 4th-generation (4G) communication system, such as long-term evolution (LTE). A method of a base station proposed in various embodiments of the present disclosure comprises the procedures of: transmitting synchronization signal blocks (SSBs) allocated on the basis of deployment information of the base station, an angle covered by each sector of the base station, and the number of SSB indices; receiving, from a terminal, an SSB index selected from among the SSBs; estimating a location of the terminal on the basis of the SSB index; estimating a speed of the terminal on the basis of the SSB index and the location of the terminal; estimating a moving section of the terminal on the basis of the speed of the terminal; and configuring a beamforming vector for the terminal on the basis of the moving section of the terminal.
