  • RADIO LINK FAILURE MANAGEMENT IN WIRELESS COMMUNICATION NETWORKS
    Publication number: 20210153276
    Abstract: In some aspects, methods, apparatuses, and computer program products are provided for handling RLC failures in PDCP duplication where there are two logical channels on which a PDCP entity can send packets. In some aspects, the radio network node may determine a mapping between the primary and secondary logical channels and serving cells, and how this mapping can be configured for the wireless device. In some aspects, the wireless device may take different actions depending on which of a primary and a secondary logical channel, i.e. RLC entity, fails. In some aspects, the wireless device operating in PDCP duplication may notify the radio network node about the failure of a radio link supporting the secondary logical channel without triggering the RLF procedure.

  • Systems and methods for removal of duplicated packets for transmission
    Patent number: 11005606
    Abstract: According to certain embodiments, a method in a wireless device includes transmitting a protocol data unit (PDU) or segment of a PDU on a first link and transmitting the PDU or the segment of the PDU on a second link. One or more retransmissions of the PDU or the segment of the PDU are scheduled on the second link. A positive acknowledgment is received from a receiver. The positive acknowledgement indicates a successful receipt of the PDU or the segment of the PDU on the first link.

  • Mobility robustness in a cellular network
    Patent number: 11005704
    Abstract: A user equipment starts a first timer in response to detecting a physical layer problem with a radio link between the user equipment and a node of a cellular network. Responsive to detecting a handover measurement event, the user equipment also starts a second timer and sends a measurement report to the node. The starting of the first and second timers causes the first and second timers to simultaneously elapse. Responsive to one of the simultaneously elapsing timers expiring, the user equipment sends a radio link failure report, to the node, indicating which of the simultaneously elapsing timers expired.

  • Duplication of Traffic of a Radio Bearer Over Multiple Paths
    Publication number: 20210084539
    Abstract: Radio network equipment (1700) is configured to implement a radio access network, RAN, central unit (12-C). The radio network equipment (1700) is configured to decide, by the RAN central unit (12-C), which of multiple RAN distributed units (12-D1, 12-D2) is to be responsible for activating duplication of traffic of a radio bearer (16) over multiple paths (16-1, 16-2). Different ones of the RAN distributed units (12-D1, 12-D2) serve different respective ones of the multiple paths (16-1, 16-2). The radio network equipment (1700) is also configured to transmit, from the RAN central unit (12-C), control signalling (20) to each of one or more of the RAN distributed units (12-D1, 12-D2) indicating whether or not the RAN distributed unit is responsible for activating duplication of the traffic of the radio bearer (16) over the multiple paths (16-1, 16-2).

  • Technique for transferring data in a radio communication
    Patent number: 10951365
    Abstract: A technique for transferring data on a radio bearer is described. The split radio bearer includes a first layer entity (570) at a first layer of a protocol stack and at least two second layer entities at a second layer of the protocol stack. The second layer is lower than the first layer in the protocol stack. In a method aspect of the technique, the data is received through each of the at least two second layer entities (582, 584). The data received through the at least two second layer entities (582, 584) is validated. If a result of the validation is indicative of an inconsistency in the data received through the at least two second layer entities (582, 584), a retransmission of the data is selectively triggered through at least one of the second layer entities (582, 584).
