UPLINK DATA SENDING METHOD, UPLINK DATA SCHEDULING METHOD, AND DEVICE

摘要

Provided in the present invention is an uplink data sending method. The method comprises: a terminal apparatus receives scheduling signaling during at least one downlink time interval in a downlink time interval set, wherein the scheduling signaling is used to schedule uplink data, and any of the downlink time interval set is within a downlink subframe n; the terminal apparatus determines an uplink time interval corresponding to the at least one downlink time interval, wherein any of the downlink time interval set corresponds to the determined uplink time interval, the determined uplink time interval is within an uplink subframe n+k, and k is equal to 0, 1, 2, or 3; and the terminal apparatus sends the uplink data during the determined uplink time interval. By employing the above solution, the present invention reduces latency between receiving scheduling information and sending uplink data.
