Abstract
An operation method of a base station in a time division duplex communication system includes: a step for setting a time period in which a terminal can transmit an uplink in a downlink period; a step for generating a sparse vector signal including information about the time period; and a step for transmitting the sparse vector signal to the terminal. In addition, an operation method of the terminal in the time division duplex communication system includes: a step for receiving a part of a sparse vector signal from the base station; a step for recovering the received sparse vector signal by compressed sensing; and a step for transmitting uplink data in a time period instructed in a downlink period based on the basis of the recovered signal.
