摘要： A technique for controlling and monitoring packet duplication of at least one packet in a radio transmission from at least one transmitting station (100) to a receiving station (200) is described. As to a method aspect of the technique, a control message (710) that is indicative of the packet duplication in the radio transmission is transmitted to the receiving station (200). The control message (710) controls the receiving station (200) to monitor a reception of duplicates (712) of the at least one packet. Two or more duplicates (712) of the at least one packet are transmitted to the receiving station (200). A control feedback (714) that is indicative of a result of the monitoring is received from the receiving station (200).

摘要： Systems and methods for dynamic and flexible configurations for configured grants are provided. In some embodiments, a method performed by a wireless device for configuring uplink grants includes receiving, from a network node, one or more indications to enable one or more configured grant configurations per cell and/or per BWP where at least one configured grant configuration indicating a plurality of transmission occasions within a period. The method also includes transmitting at least one transmission based on the at least one configured grant configuration. This may enable the use of different periodicity of mixed Time Sensitive Network (TSN), random Ultra-Reliable Low-Latency Communication (URLLC), and enhanced Mobile Broadband (eMBB) traffics; reduce the misalignment delay of the arrived data; improve the spectral efficiency of the eMBB traffic while satisfying the URLLC requirement; and/or reduce the number of Hybrid Automatic Repeat Request processes needed to transmit a considerable number of Configured Grant configurations.

摘要： Embodiments herein relate to a method performed by a transmitting device (120) for handling communication in a wireless communications network, wherein the transmitting device (120) comprises at least two radio link control, RLC, entities and is configured with a split bearer to a receiving device (100). The transmitting device (120) identifies that a last transmitted protocol data unit, PDU, of one of the at least two RLC entities, is lacking a poll indicator requesting a status of one or more transmitted PDUs. When identifying that the last transmitted PDU lacks the poll indicator, the transmitting device transmits to the receiving device (100), a PDU comprising a poll indicator.

摘要： According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.

摘要： A method of receipt status reporting in a communication device, comprising configuring (S1) said communication device for periodic receipt status reporting by associating a first status report type with a value of a first reporting periodicity parameter and associating a second status report type with a value of second reporting periodicity parameter, said first status report type being different from said second status report type and said first reporting periodicity parameter being different from said second reporting periodicity parameter, and periodically (S2) sending receipt status reports of said first type according to said associated value of said first reporting periodicity parameter and receipt status reports of said second type according to said associated value of said second reporting periodicity parameter.

摘要： A communication device receives an uplink grant from a node of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device in reoccurring time intervals. For each of these time intervals, the communication device selects between an active mode and an inactive mode. In the active mode the communication device performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device performs no uplink transmission in the allocated uplink radio resources.

摘要： In one embodiment, a method in a wireless device for adaptive HARQ retransmissions comprises receiving, from a network node, a request to initiate an adaptive hybrid automatic repeat request (HARQ) retransmission. The method comprises identifying a HARQ process associated with the HARQ retransmission request and determining whether a HARQ buffer of the HARQ process is empty. In response to determining that the HARQ buffer is empty, the method comprises not delivering the HARQ information to the HARQ process and not triggering an adaptive HARQ retransmission.

摘要： A user equipment starts a first timer and a second timer in response to different respective network events. The starting of the first and second timers causes the first and second timers to simultaneously elapse. In response to one of the simultaneously elapsing timers expiring, the user equipment sends a radio link failure report to a node of a wireless communication network indicating which of the simultaneously elapsing timers expired.

摘要： A wireless device (11, 12) determines a set of carriers. The carriers each require a listen-before-talk, LBT, procedure before transmitting on the carrier. Further, the wireless device (11, 12) determines a reliability target for a wireless transmission from the wireless device (11, 12) to the wireless communication network, in particular to an access node (101-1, 101-2, 101-3, 101-4) of the wireless communication network. Depending on the reliability target, the wireless device (11, 12) controls aggregation of carriers from the set for redundantly 10 performing the wireless transmission on the aggregated carriers.

摘要： A user equipment (UE) transmits an SR to a network node using a first transmission duration a particular number of times. The UE then determines a longer transmission duration for transmitting a further SR based on determining that no response has been received from the network node in response to any of the particular number of times the SR was transmitted. The UE transmits a further SR to the network node using the longer transmission duration.
