摘要： There is provided a method performed by a wireless device for prioritizing channel state information reports. The method comprises determining to transmit a portion of a plurality of channel state information reports that are each separately scheduled for transmission responsive to determining that the reports would be transmitted in a same slot with acknowledgement information indicating whether data was successfully or unsuccessfully received by the wireless device. The method further comprises transmitting, by the wireless device in that slot, that portion of the channel state information and the acknowledgement information. There is also provided a method performed by a base station, a wireless device and a base station.

摘要： There is disclosed a method of operating a network node in a radio access network. The method includes determining an identity associated to a second network node based on received SS/PBCH block transmission received from the second network node and based on a determined time shift of the SS/PBCH block transmission relative to a slot structure. The disclosure also pertains to related devices and methods.

摘要： In one aspect, a wireless device receives a scheduling grant and a grant confirmation signal indicating that a network node has performed a CCA on a carrier and is releasing the carrier for the wireless device. An uplink message is transmitted on the carrier without performing a CCA on the carrier. In another aspect, a wireless device is connected to a first cell and a second cell configured on a carrier requiring an LBT protocol. The wireless device receives configuration messages indicating that downlink transmissions on the second cell are to be scheduled. This can mean self-scheduling for downlink on the second cell and cross-carrier scheduling for uplink on the first cell. The wireless device receives a scheduling grant in the first cell and performs a CCA in the second cell. The wireless device then transmits an uplink message responsive to success of the CCA.

摘要： Systems and methods for uplink cancellation are provided. In some embodiments, a method performed by a wireless device for performing uplink cancellation includes receiving an indication to stop a transmission; and receiving an indication to transmit on cancelled uplink resources. In some embodiments, in response to receiving the indication to stop the transmission, performing one of: cancelling the transmission; and muting the transmission. In this way, the New Radio (NR) Uplink (UL) cancellation mechanism can be enabled on NR-Unlicensed (NR-U) resources and helps to cater Ultra-Reliable and Low Latency Communication (URLLC) services.

摘要： A method performed in a system comprising a joint traffic direction scheduler configured to coordinate time-division-duplexing (TDD) transmissions for multiple cells comprises obtaining TDD operation information from each of the cells, determining, based on the obtained TDD operation information, a transmission direction to be used by each of the cells during one or more transmission time intervals (TTIs), and indicating to the cells the determined transmission direction.

摘要： In one aspect, a network node is configured for multi-interval scheduling downlink or uplink transmissions to or from a wireless device. The network node sends (702), to the wireless device, configuration information indicating one or both of a maximum number of scheduling intervals that can be scheduled with a single scheduling message and a time-domain resource allocation data structure to be used when multi-interval scheduling is in use. Alternatively, the network node schedules (802) one or more downlink or uplink transmissions to or from the wireless communication device, using a single scheduling message scheduling a transmission in each of multiple scheduling intervals. The number of scheduled intervals is indicated in the scheduling message by a dedicated field in or by a time resource assignment indication that implicitly or explicitly indicates the number of scheduled intervals.

摘要： Methods and systems for setting Hybrid Automatic Repeat Request (HARQ) timing for Physical Downlink Shared Channel (PDSCH) with a pending PDSCH-to-HARQ-timing-indicator (PHTI) are provided. In one aspect, a method performed by a wireless device comprises: receiving a first Downlink Control Information (DCI) associated with a first Downlink (DL) data transmission, the first DCI comprising a non-numerical PHTI; receiving the first DL data transmission; determining a HARQ feedback for the first DL data transmission; receiving a second DCI associated with a second DL data transmission, the second DCI comprising a numerical PHTI indicating a location for HARQ feedback associated with the second DL data transmission; setting the location of HARQ feedback associated with the first DL data transmission to be the same as the location of HARQ feedback associated with the second DL data transmission; and transmitting the HARQ feedback associated with the first DL data transmission at the set location.

摘要： Radio communication systems, devices and methods for enabling variable subband configuration of one or more search spaces. In a first time interval, a UE attempts to decode one or more control channels on downlink or sidelink resources of a first sub band configuration. In a second time interval, the UE attempts to decode one or more control channels on downlink or sidelink resources of a second sub band configuration. The first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.

摘要： A user equipment is configured with at least two collections of uplink resources to be used for transmitting control information to a communication network. The UE receives an assignment of radio resources to be used for receiving a downlink transmission from a base station of the communication network. The UE receives an acknowledgement resource indication, ARI, indicating one of the configured collections of uplink resources to be used for transmitting control information associated with the DL transmission. Further, the UE transmits the control information to the base station on at least a subset of the indicated collection of UL resources. In example embodiments, the indicated collection of uplink resources comprises a plurality of selectable uplink resource sets. The control information is transmitted on one of the uplink resource sets which corresponds to an operational state of the communication network.
