  • Patent number: 10827384
    Abstract: Systems and methods are disclosed that relate to selecting Time Division Duplexing (TDD) subframes (SFs) where both downlink (DL) and uplink (UL) short Transmit Time Intervals (sTTIs) can be introduced without substantially affecting legacy TDD operations. In this regard, in some embodiments, a method of operation of a network node of a cellular communications network comprises partitioning a plurality of SFs into at least two sets of SFs. The at least two sets of SFs comprising a first set of SFs for legacy TDD transmissions and a second set of SFs for sTTI TDD transmissions. The method further comprises performing one or more telecommunications functions according to the at least two sets of SFs.

  • Publication number: 20200295887
    Abstract: In wireless device-to-device, D2D, communication data are transmitted directly from a first wireless device to a second wireless device. In response to the direct transmission of data, the second wireless device transmits feedback data indicating at least one quality of the data received in the second wireless device. More precisely, according to the invention, a radio access network node controls the direct transmission of data by means of downlink control information to the first and second wireless devices, and the feedback data are received in the radio access network node. The radio access network node preferably also uses the received feedback to control at least one of the first and second wireless devices.
