Abstract: The disclosure relates to a communication technique of combining a 5G communication system to support a higher data transfer rate than in a 4G system with IoT technology, and a system thereof. The disclosure provides a terminal in a wireless communication system. The terminal includes at least one processor configured to: obtain a codebook set for the terminal; generate uplink signals by using a plurality of codebooks of the codebook set; and control at least one transceiver to transmit the uplink signals to a base station. A first uplink signal of a first resource among the uplink signals is generated based on a codeword of a first codebook among codebooks and a second uplink signal of a second resource adjacent to the first resource among the uplink signals is generated based on a codeword of a second codebook which is different from the first codebook among codebooks.

Abstract: Methods and apparatuses in a wireless communication system are provided. Capability information regarding the terminal is transmitted. The capability information is associated with an X division duplexing (XDD) system. Resource configuration information is received based on the resource configuration information. A resource on which uplink control information (UCI) is to be transmitted is determined. The UCI is transmitted on the determined resource. The XDD system configures an uplink resource and a downlink resource in a same slot in different frequency resources.
