Disclosed is a connection management method for mobile device group, where the mobile device group includes a mobile device configured as a leader and a number of mobile devices configured as followers. The connection management method includes: in response to a measurement control from a first base station, the leader acquires signal quality measurement reports of all the mobile devices in the mobile device group corresponding to the first base station and a second base station, and signal quality measurement reports of all the followers in the mobile device group corresponding to the leader; the first base station determines whether to perform a handover according to the signal quality measurement reports received from the leader; and when the first base station determines to perform the handover, the first base station determines to perform a joint handover procedure or a half handover procedure according to the signal quality measurement reports.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may receive a measurement reference channel configuration from a source relay. The UE may transmit a reference channel based at least in part on the measurement reference channel configuration. The UE may receive, from the source relay, a command for the remote UE to switch from the source relay to a target relay based at least in part on a measurement of the reference channel transmitted from the remote UE. Numerous other aspects are provided.

One disclosure of the present specification provides a method by which a UE performs sidelink communication. The method may comprise the steps of: performing sidelink communication on the basis of a first RAT; switching a RAT for the sidelink communication from the first RAT to a second RAT; performing the sidelink communication on the basis of the second RAT; and communicating with a base station on the basis of NR.

A first base station receives, from a second base station with a plurality of cells, a message that includes a served cell information element for each cell of the plurality of cells, where the served cell information element for each cell indicates whether a respective cell supports at least one vehicle-to-everything (V2X) service. The first base station makes a dual connectivity decision for a wireless device. The first base station sends, to the second base station, a secondary node addition request for the wireless device based on the dual connectivity decision and the message.

Embodiments of the present disclosure relate to wireless communication in a wireless communication system. According to some embodiments of the disclosure, a method performed by a user equipment (UE) may include: accessing a base station (BS) via a Uu link; accessing the BS via a relay node in response to a channel quality of the Uu link being less than a threshold; stopping at least one of a physical layer timer and a timer associated with measurement report triggering when the at least one of the physical layer timer and a timer associated with measurement report triggering is running.

A communication apparatus that communicates with an external apparatus to transmit data to the external apparatus, the communication apparatus comprising, a first communication unit configured to communicate with the external apparatus in accordance with a first communication method, a second communication unit configured to communicate with the external apparatus in accordance with a second communication method, and a control unit configured to control operation in the first communication unit and the second communication unit, wherein the control unit controls so as to switch communication with the external apparatus to second communication by the second communication unit after performing first communication by the first communication unit, and transmit transmission target data to the external apparatus in the second communication.

There is provided an information processing device including: a processing unit configured to acquire device-related information including identification information with which a communication target device can be specified from the communication target device when first communication with the communication target device is started, and to perform a process via communication with the communication target device using the first communication or second communication whose communicable range is wider than the first communication. The processing unit starts the second communication using the acquired device-related information when the first communication is interrupted during execution of the process via communication based on the first communication and thus the process via communication that has been executed is uncompleted in the case in which the process via communication is performed using the first communication, and performs the uncompleted process via communication with the communication target device using the second communication.

In one embodiment, a portable, networked, computing device comprises a processor, a plurality of radios, and a memory. The device may be operable to pair, by at least one of the radios, with a device associated with a user. The device may then monitor, by one of the radios, a signal for a connection established with a first network. When the device determines that the signal for the first network has dropped below a threshold level of quality, it may enable access point mode for at least one of the paired devices by turning on a radio to establish a connection with a second network and thereby providing connectivity to the second network for the at least one of the paired devices. If multiple networks are available, the device may select an optimal network based on an assessment of one or more factors.

One aspect can provide a system and method for fast Wi-Fi roaming. The system can identify forwarding data associated with a first active session of a first application running on a client device coupled to a home access point (AP), determine a number of neighboring APs comprising a target AP, maintain a roaming cache on each of the neighboring APs, and synchronize the identified forwarding data associated with the first active session to the roaming cache on each neighboring AP. In response to determining that the client device is roaming to the target AP, the system can access the roaming cache on the target AP to obtain the forwarding data associated with the first active session in order to continue the first active session on the client device with reduced roaming latency, thereby facilitating fast roaming of the client device from the home AP to the target AP.

The present invention relates to a method for performing, by a first terminal, service discovery in a wireless communication system. The method for performing service discovery comprises the steps of: transmitting a handover request message to a second terminal by using near field communication (NFC); and receiving a handover selection message from the second terminal by using NFC, wherein the handover selection message may include information on a P2P connection and formation of an ASP session.
