Abstract: 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), is disclosed. The system includes an apparatus of a base station. The apparatus may include: at least one transceiver, and at least one processor connected to the at least one transceiver, where the at least one processor is configured to transmit to a terminal, configuration information of reference signals for beam management regarding a transmit (Tx) beam of the BS or a receive (Rx) beam of the terminal, transmit the reference signals to the terminal, and the configuration information comprises information related to a number of repetitions of the reference signals.

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). In a feedback method of a terminal, receiving a first subframe from a base station, detecting, from the first subframe, downlink control information (DCI) including transmission timing information and frequency resource information for feedback, creating feedback information for data decoding of the first subframe to be transmitted in a second subframe determined based on the DCI, and transmitting the feedback information, based on a time resource indicated from the transmission timing information and a frequency resource indicated from the frequency resource information in the DCI.
