Methods, systems, and devices for wireless communication are described. A method may include determining to modify current-allowed network slices used by a user equipment (UE) based on a network-trigger; identifying new-allowed network slices for the UE based on the determining; selecting a target access and mobility management function (AMF) based on the new-allowed network slices, the target AMF is accessible by the source AMF; and triggering an AMF relocation based on the selecting.

A method includes executing a first target operation in a case that a conditional reconfiguration parameter and/or an SCG deactivation command is received at a first reception occasion, where the first reception occasion includes at least one of the following occasions: a time at which an SCG is deactivated and a time at which a conditional reconfiguration related procedure is being executed. The first target operation includes at least one of the following: skipping initiating or stopping a conditional reconfiguration evaluation procedure; initiating or continuing a conditional reconfiguration evaluation procedure; skipping initiating or stopping a conditional reconfiguration execution procedure in a case that the first condition is satisfied; postponing initiating the conditional reconfiguration evaluation procedure; postponing initiating the conditional reconfiguration execution procedure in a case that the first condition is satisfied; ignoring or deleting the conditional reconfiguration parameter; activating or deactivating the SCG; and ignoring the SCG deactivation command.

An apparatus is provided, which includes a first device, a second device, and a control circuit. The first device is configured to establish a wireless link with a wireless communication device in a first communication channel. The second device is configured to perform a first scan on a second communication channel to detect whether there are any radar signals on the second communication channel for a predetermined period of time. In response to the first scan satisfying a predetermined condition, the control circuit controls the first device to move the wireless link from the first communication channel to the second communication channel.

Provided is an electronic device of a vehicle including a mobile communication module configured to transmit and/or receive data through a base station according to a first communication method based on a first frequency band, or a second communication method based on a second frequency band, and a control module configured to control an operation of the mobile communication module, wherein the control module is further configured to: determine whether there is a possibility of communication interruption with respect to the first communication method while data is being transmitted and received according to the first communication method through the mobile communication module, and, based on determining that there is the possibility of communication interruption, switch from the first communication method to the second communication method, and transmit and/or receive data, wherein the first frequency band is higher than the second frequency band.

A electronic device includes a memory, a communication circuit that supports plural frequency bands for wireless local area network (WLAN) communication, and a processor operably connected to the memory and the communication circuit. The processor establishes WLAN communication with an access point (AP) over a first frequency band among the frequency bands, compares, based on a signal of a second frequency band different from the first frequency band being detected, the first frequency band with the second frequency band, determines, based on the second frequency band being higher than the first frequency band, a change in a strength of a signal received over the first frequency band, estimates, when the change indicates an increase in the strength, a link quality for the AP over the second frequency band, and switches the first frequency band for WLAN communication with the AP to the second frequency band based on the link quality.
