Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving a message for dual-active-protocol stack (DAPs) handover (HO) from a source network entity to a target network entity, wherein carrier-aggregation (CA) is configured with the source network entity prior to reception of the message for HO, deactivating the CA in response to reception of the message for handover (HO) to activate a single carrier mode with the source network entity, and performing the HO from the source network entity to the target network entity during a HO period, wherein the single carrier mode is maintained with the source network entity during at least a portion of the HO period, and wherein connection with the target network entity is maintained during the at least the portion of the HO period.

In one aspect, there is provided a method performed by a terminal device. The terminal device has a first connection with a serving base station using a first radio-access technology, and a second connection with one or more nodes using a second radio-access technology. The method comprises: receiving, from the serving base station over the first connection, a connection configuration message, the connection configuration message comprising configuration information for the second connection; and, responsive to successful implementation of the configuration information for the second connection, transmitting a first response message to the serving base station over the first connection, the first response message comprising an indication that the configuration information was successfully implemented.

Provided are a method and apparatus for managing a radio mode capability, and an electronic device and a computer-readable storage medium. The method for managing a radio mode capability may comprises: when a condition for triggering a process of disabling of a cell with a target radio mode is satisfied, releasing a local radio resource of the target radio mode, wherein the target radio mode is a radio mode may be implemented by using the non-standalone.

Embodiments of the present disclosure relate to failure recovery for serving cell. A terminal device detects a failure on a serving cell of the terminal device. If the beam failure is detected, the terminal device transmits information concerning the detected failure to a network device. The network device is associated with the serving cell. The terminal device disables further transmission of the information to the network device.

Disclosed is an electronic device including a wireless communication circuit configured to support communication connections to one or multiple devices, at least one processor, and a memory which stores instructions causing, when executed, the at least one processor to identify whether a first communication connection to a second external device through the wireless communication circuit is disconnected, acquire, if disconnection of the first communication connection is identified, communication state information from a first external device connected through the wireless communication circuit, identify, based on the acquired communication state information, whether a second communication connection between the first external device and the second external device is disconnected, and operate in a loss occurrence mode for the second external device if disconnection of the second communication connection is identified.
