A communications network may include user equipment (UE) devices. When a first UE device becomes off-grid and has an emergency message, the first UE device may transmit device-to-device signals for receipt by a second UE device. The signals may include one or more preambles that precede the emergency message and that are used by the second UE device to perform synchronization with the first UE device. The second UE device may periodically activate a receiver during a series of windows to listen for the signals, may receive a preamble sequence during one of the windows, and may synchronize its timing to the first UE device for receipt of the emergency message based on the preamble sequence. This may allow the UE devices to be synchronized for transfer of the emergency message over long distances while consuming a minimal amount of power on the second UE device.

A control unit is configured to perform second control for stopping operation in a predetermined mode based on a second time shorter than a first time, the second time having elapsed with connection setting not made since the operation in the predetermined mode by a communication apparatus was started in a case where the communication apparatus is operating in the predetermined mode and the predetermined processing is completed.

Disclosed are techniques for wireless communication. In an aspect, a UE (e.g., an initiator UE) transmits sidelink discovery messages for beam training on a bandwidth associated with DMRS. One or more UEs (e.g., candidate responder UEs) select a beam to pair with a beam associated with one of the sidelink discovery messages, and transmit a sidelink discovery message on the selected beam. In another aspect, a UE (e.g., initiator UE) transmits a sidelink discovery message, which is forwarded to a UE, which may be a lead UE of a sidelink UE group. The lead UE adds the initiator UE to the sidelink UE group, and responds with a sidelink discovery response message and a group indication that at least indicates that the initiator UE now belongs to the sidelink UE group.

A communication system includes a central cloud server to establish a primary communication path between a radio access network (RAN) node and one or more user equipment (UEs) via a first set of edge devices of a plurality of edge devices, where each edge device is configured as a mesh node of a mesh network. The central cloud server determines a plurality of secondary communication paths between the RAN node and the one or more UEs via different sets of edge devices. The central cloud server ranks each of the plurality of secondary communication paths in terms of one or more signal quality parameters and controls switching from the primary communication path to one or more secondary communication paths configured as backup communication paths within a threshold time to maintain a continuity in service to the one or more UEs for uplink and downlink communication.

Unauthorized tracking devices, including those that change their identification information periodically, are detected to protect an individual's privacy. A mobile device of a user detects a first advertisement signal from an unknown wireless device, the first advertisement signal containing information representative of the unknown device. Multiple advertisement signals may be received as the mobile device moves a distance greater than a broadcast range away from the location where the first signal was detected. Responsive to detecting a second advertisement signal containing the same identity information after the mobile device has moved at least the distance greater than the broadcast range away from the location where the first signal was detected, the system generates an interface on the mobile device. The generated interface indicates to a user of the mobile device the presence of an unknown device.

Using inductive currents to wirelessly charge a device via a device connected to a power source. This inductive charging may result when a first mobile device recognizes a second mobile device via a wireless connection (e.g., Bluetooth, Bluetooth Low Energy (BLE), Near-Field Communication (NFC), or the like). An application stored on the first mobile device may recognize a second mobile device by transmitting an advertising packet when the first mobile device is connected to a power source. An advertising packet may be received by the second mobile device and the second mobile device may transmit a response to the advertising packet in order to generate a connection between the first and second mobile devices. The response may include data such as, connection strength, response time, connection preferences, and the like. Upon detection and connection, the second mobile device may be wireles sly charged by the first device via inductive charging.

Systems, methods, and instrumentalities are disclosed for priority handling for ProSe Communications. A relay wireless transmit/receive unit (WTRU) may act as a relay between the network and the remote WTRU. The relay WTRU may receive a temporary mobile group identity (TMGI) request message from a remote WTRU. The TMGI request message may include a TMGI, a ProSe per packet priority level associated with the TMGI, etc. The relay WTRU may receive an evolved multimedia broadcast multicast service (eMBMS) data packet from a network. The eMBMS may be associated with the TMGI. The relay WTRU may apply the received ProSe per packet priority level associated with the TMGI to the received eMBMS data packet. The relay WTRU may relay the eMBMS data packet to the remote WTRU based on the ProSe per packet priority level. The relay WTRU may forward the eMBMS data packet to the remote WTRU via a PC5 interface.

The present disclosure relates to a method, a device, and a computer program for selecting a channel in a wireless communication system, and to a recording medium therefor. The method for selecting a channel by a first device in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving a channel categorization report from a second device; and determining a channel map on the basis of at least one of the channel categorization report, a channel sensing result of the first device, and information provided by a host of the first device.

In a wireless local area network (LAN) system, a transmission STA may generate capability information related to WLAN sensing. The capability information may comprise a common part and an individual part. The common part may comprise sensing support band information including information related to whether WLAN sensing performed in a sub 7 GHz band is supported, and information related to whether WLAN sensing performed in a 60 GHz band is supported. The individual part may comprise, on the basis of the sensing support band information, at least one of capability information for WLAN sensing performed in the sub 7 GHz band, and capability information for WLAN sensing performed in the 60 GHz band. The transmission STA may transmit the capability information to a reception STA.
