摘要： Methods for a target node to establish a connection with a user equipment (UE) operating in dual connectivity (DC) with a primary cell (PCell) served by a master node and with a primary secondary cell (PSCell) served by a secondary node. The methods include receiving, from the UE, a re-establishment request message comprising parameters associated with the PSCell, a message authentication code, and an indication of the UE's selection of a target cell served by the target node as a replacement for the PCell, which utilizes a first radio access technology (RAT). The PSCell and the target cell utilize a different second RAT. The methods include, based on the parameters associated with the PSCell, determining a full UE context for the UE, and establishing a connection with the UE based on the full UE context, whereby the target cell will serve as a PCell for DC.

摘要： Example embodiments presented herein are directed towards a wireless terminal and base station, and corresponding methods therein, for providing a handover for a subset of bearers associated with the wireless terminal. The subset of bearers is less than a total number of bearers associated with the wireless terminal. Thus, upon the completion of the handover procedure, at least one bearer will stay connected with a source base station.

摘要： Systems, methods, and apparatus are disclosed for a user equipment. An example method performed by a user equipment includes establishing a connection to a Radio Access Network (RAN) via a first network node. Communications are provided over the connection using Signaling Radio Bearer 1 (SRB1) configured with a New Radio (NR) Packet Data Convergence Protocol (PDCP). After the connection is suspended, the user equipment receives a Radio Resource Control (RRC) connection re-establishment message from a second network node. The connection re-establishment message includes a radioResourceConfigDedicated information element (IE). The user equipment re-establishes the connection to the RAN by applying a Long-Term Evolution (LTE) PDCP configuration to SRB1, performing a radio resource configuration procedure in accordance with the radioResourceConfigDedicated IE, and sending an RRC connection re-establishment complete message to the second network node.

摘要： According to some embodiments, a network node is capable of operating as an integrated access and backhaul (IAB) node comprising a distributed unit (DU) and a mobile termination (MT). The IAB node performs a method comprising: obtaining (2012) configuration information for establishing an interface between the IAB node DU and a target IAB donor central unit (CU); and after a handover of the IAB node to the target donor, establishing (2114) the interface between the IAB node DU and the target IAB donor CU based on the obtained configuration information.

摘要： A radio network equipment central unit (20, 1700) receives a message (15) that indicates an update to a transport layer address of a radio network equipment distributed unit (10, 1600) from an old transport layer address (12A) to a new transport layer address (12B). The message (15) indicates the old transport layer address (12A) and indicates the new transport layer address (12B). The message (15) may be received from the radio network equipment distributed unit (10, 1600), or from a distributed unit of an integrated access backhaul donor. Regardless, for each of multiple user plane bearers or transport layer tunnels that are associated with the old transport layer address (12A), the radio network equipment central unit (20, 1700) may update a transport layer address of that bearer or tunnel from the old transport layer address (12A) to the new transport layer address (12B).

摘要： According to certain embodiments, a method performed by a wireless device (110) for measurement reporting includes sorting a plurality of measurements for a measurement report based on at least one measurement quantity. The method further includes reporting, to a network node (160), measurement information selected from the plurality of measurements sorted based on the at least one measurement quantity.

摘要： A wireless device (16) receives a control message (26) indicating a conditional configuration (28-1) that the wireless device (16) is to add, modify, or release for a link (20). The control message (26) includes configuration-specific information (30-1) that distinguishes the conditional configuration (28-1) from one or more other conditional configurations that are configurable for the link (20). The configuration-specific information (30-1) may for example includes a conditional configuration identifier that is unique at least among any conditional configurations configured for the link (20).

摘要： According to some embodiments, a method for use in a user equipment (UE) of resuming a radio bearer in a wireless communication network comprises: establishing a radio resource control (RRC) connection with a first network node; receiving a connection suspend message from the first network node; storing a configuration of a radio bearer associated with the RRC connection; suspending the radio bearer associated with the RRC connection; receiving a connection resume message; determining whether the connection resume message includes configuration information for NR packet data convergence protocol (PDCP) for the suspended radio bearer; upon determining the connection resume message includes configuration information for a NR PDCP, configuring the suspended radio bearer with the configuration information; and resuming the suspended radio bearer.

摘要： A communication device configured to operate in dual connectivity (DC) with a master node (MN) and a secondary node (SN) can be configured with a master cell group (MCG) configuration associated with the MN and a secondary cell group (SCG) configuration associated with the SN. The communication device can detect a radio link failure on the MCG. The communication device can further determine whether a primary secondary cell group cell (PSCell) change procedure is ongoing. The communication device can further respond to the radio link failure on the MCG based on whether the PSCell change procedure is ongoing.
