摘要： A method performed by a User Equipment (UE) for handing a Radio Link Failure (RLF) on a first group of cells in a wireless communication network is provided. The UE is engaged in an ongoing communication with the wireless communication network via a first group of cells and a second group of cells. The UE detects (501) that an RLF is on one or more out of the first group of cells. The further UE sends (502) a report to a network node in the wireless communication network. The report is sent via one or more out of the second group of cells while continuing the communication with the wireless communication network. The report comprises radio link information about the RLF on one or more out of the first group of cells.

摘要： A method for dynamic link selection that comprises providing at least two wireless links between one or more network nodes and a wireless device. The at least two wireless links associated with at least two different radio access technologies. The method additionally includes obtaining control data to be sent to a first network node of the one or more network nodes. The control data is associated with a first radio access technology. The method additionally includes selecting one or more wireless links from among the at least two wireless links. The one or more links selected based on a first selection parameter. The one or more selected wireless links are to be used for the transmission of the control data to the first network node. The one or more selected wireless links comprise at least a first wireless link associated with a second radio access technology. The method further includes transmitting the control data associated with the first radio access technology to the first network node via at least the first wireless link associated with the second radio access technology. The method also includes obtaining the control data at the first network node and determining whether the received control data is duplicated control data.

摘要： A network node may be operated to support dual connectivity communication with a wireless terminal as a main network node in cooperation with a secondary network node. Dual connectivity communication with the wireless terminal may be provided in cooperation with the secondary network node. Responsive to deciding to suspend the dual connectivity communication with the wireless terminal, a connection release message may be transmitted to the wireless terminal, a suspension indication message may be transmitted to the secondary network node, and the dual connectivity communication with the wireless terminal may be suspended. While the dual connectivity communication is suspended, a page may be transmitted to the wireless terminal indicating arrival of downlink data for the wireless terminal and then a measurement report may be received from the wireless terminal providing radio link measurement information for radio links with the main network node and/or the secondary network node.

摘要： A UE operating in a RAN may be configured to receive new radio, NR, radio resource control, RRC, messages from a secondary network node. The NR RRC messages may each contain a number that the secondary network node added to the NR RRC messages to indicate their respective order in a sequence which the NR RRC messages were sent by the secondary network node. The NR RRC messages may each contain parameters that the UE uses to configure its communications through a NR interface with the secondary network node. The UE may send NR RRC complete messages toward the secondary network node responsive to receipt of the NR RRC messages, wherein the NR RRC complete messages each contain an indication of the NR RRC message that was received. The UE may control the sending of the NR RRC complete messages to indicate to the secondary network node whether the NR RRC messages are received in an order that is the same as the sequence.

摘要： According to certain embodiments, a method by a first network node operating as a secondary node for a wireless device having dual connectivity to the first network node and a second network node operating as a source master node is performed during a handover of the wireless device from the second network node operating as the master node to a third network node operating as a target master node. The method includes receiving, from the second network node operating as the source master node, an indication that the first network node is to release one or more resources for serving user plane data to the wireless device. In response to the indication, control plane data is transmitted to the wireless device while ceasing to provide user plane data to the wireless device.

摘要： According to certain embodiments, disclosed is a method in a master node (MN) for minimizing user plane interruption delay. The method includes transmitting a handover request message to a secondary node (SN), receiving a handover request acknowledge message from the SN, and transmitting a reconfiguration instruction to a wireless device operating in dual connectivity with the MN and the SN. The reconfiguration instruction may include a new configuration wherein the SN is a target SN and an indication of a trigger used to switch to the new configuration.

摘要： A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

摘要： Systems and methods are disclosed herein that relate to Dual Connectivity (DC) for a wireless device is a wireless communication network. In some embodiments, a method in a secondary node for providing, along with a master node, DC for a wireless device such that the wireless device is configured to utilize resources provided by both the master node and the secondary node in a wireless communication network is disclosed. The method comprises receiving, from the master node, a release request. The release request is a request to release a wireless device context of the wireless device or to release resources for the wireless device. The method further comprises sending a release reject to the master node. The release reject is an indication that the secondary node rejects the release request.

摘要： In a wireless communication network that implements the RRC Resume procedure, an eNB (11) sends to a radio network device (30), which was previously connected and has been given a Resume ID, a paging message or Random Access Response message including an RRC Resume directive. The RRC Resume directive comprises at least an indication whether or not the radio network device (30) should perform an RRC Resume procedure. If the RRC Resume directive indicates the radio network device (30) should not perform an RRC Resume procedure, the radio network device (30) performs an RRC Connection procedure. If the RRC Resume directive indicates the radio network device (30) should perform an RRC Resume procedure, it may include additional information to optimize or otherwise assist the RRC Resume procedure. In this manner, RRC Resume signaling is avoided when the eNB (11) knows that it will not be successful, such as if a prior RRC connection context is not available or readily retrievable, or is invalid.
