The present disclosure relates to handling mobility in dual connectivity in wireless communication system. According to various embodiments, a method performed by a target secondary node (SN) for a primary secondary cell (PSCell) mobility of a wireless device from a source SN in a wireless communication system comprises: receiving, from a master node (MN), a message for informing a trigger of the PSCell mobility; obtaining inactivity status information informing that the wireless device is in an inactive state; and releasing or suspending lower layers for a communication with the wireless device based on the inactivity status information after the PSCell mobility of the wireless device to the target SN is completed, wherein the lower layers comprises at least one of a physical (PHY) layer, a media access control (MAC) layer, or a radio link control (RLC) layer.

The application relates to the field of wireless communication, and discloses a roaming method in a multi-link scenario, a multi-link device and a storage medium. The roaming method in the multi-link scenario includes: selecting a target network access device that meets a condition; disconnecting a logical entity on a secondary link of an original network access device from the original network access device; establishing a connection of the logical entity with the target network access device; determining a link through which the logical entity is connected with the target network access device as a primary link; and disconnecting a connection of the other logical entity other than the logical entity with the original network access device. The application realizes roaming of a terminal among different network access devices through link management and interactive control, ensuring service continuity and avoiding packet loss.

Disclosed are a method for modification in dual-connection mode and a device, for use in solving the problem that the communication performance of a terminal is easily reduced after establishment or modification in the current dual-connection architecture. The method for modification in dual-connection mode provided in the present application comprises: an MN determines an SN for flow transfer, the MN sending to the SN a transfer instruction carrying the indication information of the PDU session to which the flow belongs, so that the SN determines, according to the received transfer instruction, whether to receive the flow transferred by the MN, wherein the indication information of the PDU session is used for indicating whether the MN transfers part or all of the flow under a PDU session. The method effectively improves the communication performance of a terminal in a communication process.

A (repeater) node may identify a first indication of a waveform switch associated with a first link between a base station and the node or a second link between the node and a UE. A waveform switch associated with the first link may be triggered by the base station or the node. A waveform switch associated with the second link may be triggered by the node or the UE. The waveform switch may correspond to a first switch from an OFDM waveform to an SC waveform or a second switch from the SC waveform to the OFDM waveform. The base station may transmit, to the node, an indication of a post-waveform switch resource mapping between a first waveform associated with the first link and a second waveform associated with the second link. The node may execute the waveform switch associated with the first link or the second link.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that transmission of one or more first messages, to a wireless device and via a first radio access technology (RAT), does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT. The UE may adjust a prioritization of the one or more first messages or the one or more second messages to prioritize the transmission of the one or more first messages over the one or more second messages. Numerous other aspects are described.

A method in a wireless terminal operating in a 3GPP wireless communications network for controlling using MPTCP with a WLAN network, The method comprises receiving from the 3GPP wireless communications network system information comprising a condition for MPTCP with a WLAN network, the condition being associated with mobility characteristics of the wireless terminal.

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select at least one target node for a radio resource control connection, wherein the user equipment is in a particular radio resource control communication state when the at least one target node is selected, and wherein the user equipment is configured to communicate using dual-connectivity, wherein context information associated with the user equipment is stored by the user equipment, a master node associated with the user equipment, and a secondary node associated with the user equipment based at least in part on the user equipment being in the particular radio resource control communication state; and/or transmit information to the at least one target node or the master node to cause the context information to be provided to the at least one target node. Numerous other aspects are provided.

A user equipment configured to operate in a Long Term Evolution (LTE) network. The user equipment comprises transceiver circuitry that operates the user equipment in either of two modes, the two modes comprising: i) a first mode in which the transceiver circuitry performs packet data services in the LTE network and performs voice calls in the LTE network using a Voice over LTE (VoLTE) service; and ii) a second mode in which the transceiver circuitry performs packet data services in the LTE network and performs voice calls in a legacy network. The user equipment also comprises a controller that compares a link quality associated with a radio link to the LTE network to at least one threshold value and, in response to the comparison, controls switching the user equipment between the first mode and the second mode. The controller switches the user equipment from the first mode to the second mode if the link quality falls below a first drop threshold value associated with an RSRP value or an SINR value. The controller switches the user equipment from the first mode to the second mode if the link quality falls below the first drop threshold value for more than a drop period of time threshold value.

A handover method, information exchange method, device and computer readable storage medium are provided. In some embodiments, a first network device may acquire multi-connectivity capability information of a candidate second network device during a handover process, so that the first network device may select, based on the multi-connectivity capability information, a candidate second network device capable of providing an multi-connectivity service as a second network device.
