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.

Abstract: Methods and apparatuses are provided in which a radio resource control (RRC) message is transmitted to a terminal. A set of values for an offset between a transmission time interval (TTI) with a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) to a TTI where the PUSCH is transmitted is included in the RRC message. First DCI scheduling a first PUSCH is transmitted to the terminal. A number of bits associated with one value in the set of values is included in the first DCI. Uplink data on the PUSCH is received from the terminal, in a TTI determined by using the RRC message and the number of bits in the DCI.

Abstract: Methods and apparatuses are provided in which a radio resource control (RRC) message is transmitted to a terminal. A set of values for a timing between a physical downlink shared channel (PDSCH) and acknowledgement information is included in the RRC message, and the set of values is respectively associated with a set of numbers of a transmission time interval (TTI). First downlink control information (DCI) for a first PDSCH is transmitted to the terminal. A number of bits associated with one value in the set of values is included in the DCI. The first PDSCH is transmitted to the terminal. Acknowledgement information for the first PDSCH is received from the terminal, based on a transmission timing determined by using the RRC message and the number of bits in the DCI.
