Abstract: A method and apparatus are provided for setting a plurality of demodulation reference signal (DMRS) structures and determining uplink and downlink transmission timing for reducing a delay. A method performed by a terminal includes receiving, from a base station, information associated with a first symbol position for a demodulation reference signal (DMRS) in a transmission time interval; identifying the first symbol position for the DMRS, the first symbol position for the DMRS being identified relative to a start of the transmission time interval based on the information; and receiving, from the base station, the DMRS on the identified first symbol position of the DMRS.

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.
