    摘要： Systems and methods are disclosed for determining and utilizing uplink scheduling timing for reduced processing time. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises receiving an uplink grant in a Transmission Time Interval (TTI) n, determining an uplink scheduling timing l based on a configured Time Division Duplexing (TDD) uplink/downlink configuration, and transmitting, in a TTI n+I, an uplink transmission in accordance with the uplink grant received in the TTI n. The uplink scheduling timing I is a number of TTIs that is larger than or equal to a predefined minimum uplink scheduling timing value such that n+I is an uplink TTI and the predefined minimum uplink scheduling timing value is 2 or 3.

    摘要： It is presented a method performed by a network node of a wireless communication network for scheduling a wireless device in uplink. An uplink signal structure is configured to be used by the wireless device and the network node, wherein the uplink signal structure defines transmission subframes divided into symbol periods. The network node applies a short Transmission Time Interval, sTTI, scheduling interval, wherein each sTTI is shorter in time than a subframe and each sTTI comprises at least one symbol period. The method comprises: transmitting a control information message to the wireless device for an sTTI scheduling interval, the control information message comprising uplink scheduling information assigned to the wireless device, the uplink scheduling information indicating a position and a length for at least one of a reference signal and data in the uplink sTTI.
