  • QoS and hop-aware adaptation layer for multi-hop integrated access backhaul system
    Patent number: 11064417
    Abstract: A node maps end-user bearers to backhaul bearers in an adaptation layer. The node maps a plurality of end-user bearers to backhaul bearers in consideration of QoS classes for the end-user bearers and a distance from the node to a destination relay node for each of the plurality of end-user bearers, such that at least one of the backhaul bearers carries end-user bearers with different QoS classes and different distances to the destination relay node. The distance from the node to the destination relay node for at least one of the end-user bearers may be considered in terms of a number of remaining hops from the node to the destination relay node and/or in terms of an estimated end-to-end delay from the node to the destination relay node.

  • RRC Connection Establishment, Re-Establishment, and Resumption in a Wireless Communication System
    Publication number: 20210212145
    Abstract: A wireless device (14) transmits, to a radio network node (12), a radio resource control (RRC) connection request (18) that requests the establishment, re-establishment, or resumption of an RRC connection (16). The RRC connection request (18) indicates a type of core network to which the wireless device (14)selects to connect. The wireless device (14) in some embodiments receives a response to the RRC connection request (18), based on the type of core network to which the wireless device (14) selects to connect. For example, the wireless device (14) may receive the response using a protocol stack determined based on the type of core network to which the wireless device (14) selects to connect.

  • Methods for handling radio access network notification area (RNA) update configuration upon reject
    Patent number: 11012848
    Abstract: A wireless device handles area update reports. The wireless device initiates a radio network area update, RNAU, responsive to detecting that the wireless device has entered a cell not belonging to a radio network area, RNA, configured for the wireless device. The wireless device receives, from the wireless network, a message indicating that the wireless device's attempt to perform the RNAU has been rejected. The message includes or is accompanied by an indication that a wait time value is applicable. Responsive to the message, the wireless device sets a reject wait timer to the wait time value and performs the RNAU upon expiry of the reject wait timer. In some embodiments, the wireless device sets a periodic RNAU timer to the wait time value, responsive to the message, and performs the RNAU upon expiry of the reject wait timer and the periodic RNAU timer.

  • Method and arrangement in a telecommunication system
    Patent number: 11006267
    Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

  • Methods for Handling Periodic Radio Access Network Notification Area (RNA) Update Configuration Upon Reject
    Publication number: 20210127445
    Abstract: According to an aspect, a user equipment, UE, in a suspended state in a Radio Access Network, RAN, in response to expiration of a first timer, transmits (1910) an RRCResumeRequest message. The UE receives (1920) a reject message in response to the RRCResumeRequest message. In response to the reject message, the UE starts (1930) a second timer and subsequently transmits (1940) a further RRCResumeRequest message. The further RRCResumeRequest message is received by the network during a period hounded approximately by the lesser of a duration of the second timer and a period of the periodic UE event and the greater of the duration of the second timer and the period of the periodic UE event.
