Abstract: Embodiments include methods for a user equipment (UE) configured to operate in a radio access network (RAN). Such methods include receiving, from a radio node in the RAN, a new feedback indicator (NFI) that indicates whether acknowledgement signaling previously scheduled for transmission by the UE was received by the radio node. The acknowledgement signaling is associated with one or more first downlink (DL) hybrid ARQ (HARQ) processes. Such methods include, when the NFI indicates the acknowledgement signaling was not received by the RAN node, selecting a first HARQ codebook to be used for encoding the acknowledgement signaling together with further acknowledgement signaling associated with one or more second DL HARQ processes. Such methods include, using the selected first HARQ codebook, encoding the acknowledgement signaling and the further acknowledgement signaling to obtain first encoded information and transmitting the first encoded information to the radio node via an uplink (UL) channel.

Abstract: An example method is performed by a wireless device in a wireless communication network. The method comprises receiving, from a base station, a control message allocating resources in a bandwidth part for a downlink transmission, the bandwidth part including unlicensed spectrum and being divided into a plurality of bandwidth pieces corresponding to bandwidth units over which listen-before-talk (LBT) is performed. The radio resources used for the downlink transmissions exclude (e.g., by puncturing or rate-matching around) one or more guard bands of a bandwidth piece that is sensed as free for transmission.

Abstract: A method performed by a wireless device 410 is provided for receiving an uplink scheduling grant for a plurality of physical uplink shared channels (PUSCHs). The method includes receiving, from a network node 460, downlink control information (DCI). The DCI includes an indication corresponding to at least a time domain resource for each of the plurality of PUSCHs. Based on the indication, uplink scheduling grant resources are determined for the plurality of PUSCHs. At least one transmission is sent according to the determined uplink scheduling grant resources.

Abstract: A method performed by a wireless device (410) includes transmitting an uplink, UL, burst to a network node (460). The UL burst includes UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH. The UCI carries one or more parameters for unlicensed operation, and the UL burst has an associated UL burst structure. The UL burst structure includes a first slot, a full slot, and a last slot.

Abstract: Embodiments herein relate to a method performed by a first communication node operating in a wireless communications network. The first communication node adjusts a value of a Contention Window, CW, from a first value to a second value, the second value being a higher value than the first value, wherein adjusting the value is based on: one or more feedback timers having expired at a time of performing a sensing procedure in the absence of: a) a received uplink, UL, grant from a second communication node, or b) a downlink feedback from the second communication node for an Autonomous Uplink, AUL, transmission from the first communication node. Following adjusting the value, the first communication node initiates a sensing procedure performed prior to a transmission of an UL burst to the second communication node, wherein the sensing procedure uses the adjusted value of the CW.

Abstract: Embodiments include methods, performed by a user equipment (UE), for transmitting information on an uplink (UL) shared channel within a cell of a radio access network. Such embodiments include receiving, from a network node serving the cell, a configured uplink grant of resources for transmitting information on the UL shared channel. The uplink grant can indicate particular timeslots during which transmission on the UL shared channel is allowed and can include: a periodicity parameter indicating an uplink periodicity for configured resources, and an allowance parameter indicating a number of timeslots, within each uplink periodicity, during which transmission on the UL shared channel is allowed. Such embodiments also include transmitting information on the UL shared channel during at least one of the particular timeslots indicated by the uplink grant. Embodiments also include complementary methods performed by a network node, and UEs and network nodes configured to perform such methods.
