A method performed by a User Equipment (UE) for handling a Conditional Handover (CHO) from a first cell to a second cell in a wireless communications network. The UE is served by a Master Node (MN), in the first cell and by a Secondary Node (SN) in a third cell. The UE receives a CHO configuration from the first network node acting as the MN. The CHO configuration includes an indication to release configurations of any one or more out of: Multi Radio Access Technology Dual Connectivity (MR-DC), and SN terminated bearers. Upon execution of the CHO according to the CHO configuration, the UE releases the MR-DC configuration and/or a configuration for SN terminated bearers.

Aspects of the present disclosure propose solutions to a problem of mobility interruption during handover between base stations by providing a UE with mechanisms to report the UE capability for simultaneous connectivity based handover, or so-called Dual Active Protocol Stack Handover (DAPS-HO). A UE reports the DAPS-HO capability of the UE to the network and then the base station initiates physical layer procedures to carry out DAPS-HO in accordance with the DAPS-HO capability reported by the UE. Aspects of the present disclosure also provide examples of signaling that may be used by the UE for reporting DAPS-HO capability to the network and the physical layer procedures that the UE may follow in accordance with the configuration that the network provides to the UE, which should be in accordance with the UE's capability.

A method for seamless WiFi roaming of a multi-radio station when transitioning from an initial access point to a target access point, wherein the method comprises activating a second communication link between the multi-radio station and the target access point while a first communication link between the multi-radio station and the initial access point is still active, and after said activating, deactivating the first communication link between the multi-radio station and the initial access point.

A method includes receiving a first message from a first master node. The first message includes an identifier of a first candidate primary secondary cell (PSCell) or an identifier of first configuration information of the first candidate PSCell. The first candidate PSCell is included in both a first PSCell list and a second PSCell list. Alternatively, the first message includes delta configuration information of a second candidate PSCell in the second PSCell list. The first configuration information of the first candidate PSCell includes an addition/change condition and a configuration of the first candidate PSCell. The first PSCell list includes one or more candidate PSCells configured by the first master node for a terminal. The second PSCell list includes one or more candidate PSCells configured by a second master node for the terminal. The method also includes adding a target PSCell or changing from an original PSCell to the target PSCell.

A first radio base station informs a second radio base station about the configuration information of a second carrier, such as NBC or EC, not having an individual first identifier, as the configuration information of the second carrier is correlated with a first carrier, such as BC, having the individual first identifier. The radio station has a function of performing communication with a radio terminal using simultaneously a plurality of carriers included in the carrier set.

In a method for adapting a mobile network, a terminal is connected to a first access node of the mobile network via a first connection and to a second access node via a second connection. The first access node controls a data transmission for the terminal and the second access node assists in the data transmission for the terminal. The method comprises determining whether a quality of at least one of the first connection and the second connection is degraded, acquiring quality degradation information about the degradation of the quality of at least one of the first connection and the second connection based on the step of determining, and adapting the mobile network based on the step of acquiring.

Provided are a neighbor relation maintenance method and apparatus, including: a first node configuring measurement and instructing a terminal to report ANR-related information, or requesting a second node to configure measurement and instruct the terminal to report the ANR-related information. If the first node configures measurement and instructs the terminal to report ANR-related information, the first node maintains a neighbor relation of a cell in the first node based on the ANR-related information, and forwards the ANR-related information to the second node for maintaining a neighbor relation of a cell in the second node; if the second node configures measurement and instructs the terminal to report ANR-related information, the second node maintains the neighbor relation of the cell in the second node based on the ANR-related information, and forwards the ANR-related information to the first node for maintaining neighbor relation of the cell in the first node.

An electronic device is provided. The electronic device includes: wireless communication circuitry, at least one processor operatively connected with the wireless communication circuitry, and a memory operatively connected with the at least one processor. The memory stores instructions which, when executed, cause the at least one processor to control the electronic device to: identify a state of the electronic device, receive a system information block (SIB) from a first base station supporting a first cellular network via the wireless communication circuitry, identify whether a network to which the electronic device belongs supports dual connectivity (DC) between the first cellular network and a second cellular network based on information included in the SIB, enable a second cellular network function of the wireless communication circuitry based on the network supporting the DC, and transmit information indicating that the second cellular network function of the electronic device is enabled to the network via the wireless communication circuitry.

Provided in the present disclosure are a method for radio link failure recovery and user equipment. The method for radio link failure recovery comprises: user equipment (UE) detecting that a handover failure occurs, and when the UE has a stored conditional handover (CHO) configuration, or when the UE has a stored conditional handover (CHO) configuration and CHO recovery is enabled, the UE reverting back to a configuration used in a source cell, the configuration used in the source cell including one or more of a physical layer dedicated configuration, a medium access control (MAC) layer configuration, or a semi-persistent SPS configuration.

An electronic device is provided. The electronic device includes at least one processor, and the at least one processor be configured to establish a first connection based on a first radio access technology (RAT) with a first network and a second connection based on a second RAT with a second network, identify uplink data, based on a condition that associates the uplink data with an acknowledgment (ACK) or a negative acknowledgment (NACK) corresponding to downlink data from the first network and/or the second network being satisfied, transmit the uplink data corresponding to the ACK or the NACK, based on a RAT among the first RAT or the second RAT, regardless of whether a size of the uplink data is larger than or equal to a threshold set regard to the dual connectivity, and based on the condition not being satisfied, transmit the uplink data, based on a RAT corresponding to a primary path among the first RAT or the second RAT, according to whether the size of the uplink data is larger than or equal to the threshold, or transmit the uplink data using both the first RAT and the second RAT.
