摘要： Systems and methods for determining and utilizing an uplink scheduling timing when using short Transmission Time Intervals (sTTIs) are disclosed. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises receiving an uplink grant in sTTI n; determining, based on a configured uplink/downlink configuration, an uplink scheduling timing I; and transmitting, in a sTTI n+I, an uplink transmission in accordance with the uplink grant received in the sTTI n. In this manner, an uplink timing is determined and utilized when using sTTIs.

摘要： Systems and methods for determining and utilizing downlink Hybrid Automatic Repeat Request (HARQ) timing when using short Transmit Time Intervals (sTTIs) are disclosed. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises determining a downlink HARQ timing k for transmission of downlink HARQ feedback for a downlink transmission received in a downlink sTTI nDL based on a Time Division Duplexing (TDD) uplink/downlink configuration and transmitting, in an uplink sTTI nDL+k, downlink HARQ feedback for the downlink transmission received in the downlink sTTI nDL. In this manner, downlink HARQ timing is determined and utilized when using sTTIs.

摘要： A method (110) in a user equipment (105;505) for transmitting a demodulation reference signal in a communications network (100). The method comprises determining (111) multiplexing information for the demodulation reference signal, and transmitting (113) the demodulation reference signal using the multiplexing information in a same time allocation as a demodulation reference signal of another user equipment. The method further comprises transmitting (115) data symbols associated with the demodulation reference signal in a separate time allocation of physical resources, and on a same physical frequency resource, to a time allocation of data symbols of the said another user equipment.
