    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.

    摘要： A radio network node, such as a gNodeB (gNB), in a radio network and a User Equipment (UE) and a method, for configuring the UE camping on a cell in the radio network for Synchronization Signal (SS) Blocks based cell re-selection measurements for RRC_IDLE and RRC_INACTIVE states. The method comprises providing information, such as system information (SI), to the UE, including configuration parameters for a measurement window, the configuration parameters defining a window periodicity, a window offset and a window duration, for the SS Blocks based cell re-selection measurements for RRC_IDLE and RRC_INACTIVE states.

    摘要： Methods of operation of a wireless device are provided. In particular, Media Access Control (MAC) protocol aspects are disclosed relating to Licensed Assisted Access (LAA) cells and, more generally, to cells of a cellular communications network operating in an unlicensed frequency spectrum. According to one aspect, a method of operation of a wireless device comprises transmitting an Uplink (UL) transmission on a cell for a corresponding UL Hybrid Automatic Repeat Request (HARQ) process, the cell operating in an unlicensed frequency spectrum, and setting a locally maintained status for the UL HARQ process to Acknowledgement (ACK) based on an assumption that the UL transmission was successful.

    摘要： According to certain embodiments, a method for use in a wireless device is disclosed. The method comprises: receiving, from a network, a Physical Random Access Channel (PRACH) configuration index; receiving, from the network, radio resource control signaling including a bitmap that provides an indication of synchronization signal (SS) blocks of an SS burst set being transmitted by the network; and restricting random access preamble transmission in response to determining that the wireless device is operating in an unpaired spectrum. The restricting includes determining, based on the PRACH configuration index and the bitmap, a time slot between transmitted SS blocks of the SS burst set that does not overlap with the transmission of the indicated SS blocks. The method further comprises transmitting a random access preamble during the determined time slot.

    摘要： A contending radio node (200) is configured for attempting contention-based random access. The contending radio node (200) obtains a timing advance sequence that is susceptible to contention. The contending radio node (200) transmits, using the same transmission advancement timing, the timing advance sequence and a contention-resolving identity to a recipient radio node (250). Responsive to that transmission, the contending radio node (200) receives a response signal that indicates a contention-resolving identity and a timing advance. The contending radio node (200) resolves any contention in its favor when the contention-resolving identity indicated by the response signal corresponds to the contention-resolving identity that the contending radio node (200) transmitted. The contending radio node (200), responsive to resolving the contention in its favor, adjusts its transmission advancement timing according to the timing advance indicated by the response signal.

    摘要： According to some embodiments, a method in a network node comprises: determining that uplink control information, UCI, and a data payload will be sent via a physical uplink shared channel on a slot/subslot transmission; determining a modulation coding scheme, MCS, offset for transmission of the UCI via the physical uplink shared channel; and communicating the MCS offset to a wireless device. According to some embodiments, a method in a wireless device comprises: determining that UCI and a data payload will be sent via a physical uplink shared channel on a slot/subslot transmission; receiving a MCS offset for transmission of the UCI via the physical uplink shared channel; and communicating, to a network node, the UCI using the MCS offset. The UCI and the data payload may be sent via the physical uplink shared channel with a slot/subslot transmission or a short transmission time interval (sTTI).
