  • Publication number: 20180115984
    Abstract: 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.

  • Publication number: 20170257199
    Abstract: There is provided mechanisms for transmitting payload in a subframe. A method is performed by a first network device. The method comprises obtaining a transport block size (TBS) value by accessing an array storing a plurality of TBS values. The TBS value is proportional to number of user data symbols in a subframe of a given subframe length. One and the same array is accessed regardless of the given subframe length. The method comprises transmitting a physical channel carrying payload in the subframe to a second network device. The amount of data in the payload is determined by the TBS value.
