A method and apparatus for a secondary cell group (SCG) failure handling with a conditional primary secondary cell (PSCell) configuration in a wireless communication system is provided. A wireless device evaluates a conditional change of PSCell based on a mobility command for the conditional change of the PSCell. Upon detecting a failure on a secondary cell group (SCG), the wireless device stops evaluating the conditional change of the PSCell, and transmits, to the network, information on the failure on the SCG.

Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Embodiments of the present disclosure are directed to a switching method and a switching device. When a mobile terminal needs to be switched from a first communication network to a second communication network, detecting whether the mobile terminal is in a ringing state. When the mobile terminal is in the ringing state, detecting whether the mobile terminal is switched from the ringing state into a connecting state within a predetermined time period. When the mobile terminal is switched from the ringing state into the connecting state within the predetermined time period, performing an IMS registration through the second communication network to connect the mobile terminal to the second communication network.

A method performed by a source master node performing a handover of a wireless device to a target node includes receiving, from a source secondary node, a first message comprising the secondary node configuration and a conditional reconfiguration. The source master node transmits, to the target node, a handover request message that includes an indication that the wireless device is configured with the conditional reconfiguration. The source master node receives, from the target node, a handover acknowledgement message indicating that the wireless device is to keep, modify, and/or release the conditional reconfiguration.

Systems and methods are provided for reducing communications between servers and a mobile device and providing enhanced security and privacy to wireless beacon services. This can involve a broadcast device transmitting a beacon transmission using a short range wireless radio, such a Bluetooth or WiFi, and including a MAC address, a first unique identifier, and a beacon service identifier. The mobile device then selects one or more unique identifiers from received beacon transmissions, by filtering (that is, selecting) those beacon transmissions which include the beacon service identifier. The wireless device then takes further action, if the first unique identifier is present among the selected one or more unique identifiers, using stored information from the server. The stored information may be delivered to the wireless device in response to the wireless device sending the first unique identifier to a server, or the stored information may have been previously downloaded.

The present disclosure provides a connection re-establishment method and related device, the method including: performing a handover process; and initiating a connection re-establishment on the first node if a re-establishment trigger condition is satisfied by a terminal, wherein the first node includes at least one of a source node or a target node in the handover process.

In various embodiments, an access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value instructs a station that has accessed a channel to hand over a held TXOP to the access point, and the second value instructs the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.

A method and apparatus are provided for measuring at least one neighboring cell by a user equipment (UE) in a communication system. The method includes identifying a serving cell quality threshold and measurement configuration information used for setting up measurement gap patterns; performing measurement of the at least one neighboring cell based on a serving cell quality measured by the UE, the serving cell quality threshold, and the measurement configuration information; and transmitting a measurement report based on the measurement. The measurement is performed in accordance with a plurality of measurement types, and the measurement gap patterns correspond to the plurality of measurement types.
