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.
