Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining a configuration of resources for discovery of a relay UE of a plurality of relay UEs, wherein the resources are used by each of the plurality of relay UEs for communication of one or more discovery messages, performing discovery operations to connect with the relay UE in accordance with the configuration, and communicating with a base station through the relay UE after connecting with the relay UE.

This application provides a data transmission method and an electronic device. The method includes: Each electronic device may form a network topology relationship in advance. A first electronic device and a second electronic device may directly transmit first data based on path information determined based on network topology relationship.

A method is described for communication in a tactical network. A gateway is communicatively COUPLABLE to one or more tactical nodes and to one or more other gateways. The gateway is programmed to transmit information to and/or receive information from other gateways. Information exchanged includes gateway attributes, link attributes, service availability, and/or data availability. The gateway optionally provides quality of service, distributed persistence, load balancing, and/or transformation services. Services are provided in a modular, service-oriented architecture (SOA) to accommodate the addition of services and/or applications.

An apparatus operated as a relay node in a wireless mesh network for route discovery comprises processing circuitry that receives, from a first neighbor node, a discovery request including a request for a route to a destination node. When the routing table of the first node contains routes to the destination node, the first node sends, to the first neighbor node, a discovery response including information about these routes. When the routing table of the first node does not contain a route to the destination node, the first node sends, to a second neighbor node, a discovery request for a route to the destination node. When the first node receives, from the second neighbor node, a discovery message including information of routes to a destination node. The first node transmits, to the first neighbor node, a discovery response including information of these routes.

A delay tolerant network is built with the use of a plurality of information transfer devices each of which includes: a communication unit to communicate to and from another device within a communication range that is connected to the information transfer device; and a storing unit to store and keeps collected notification information, and each of which holds delay tolerant communication by exchanging the collected and kept notification information with another device when the exchange becomes possible. Each information transfer device includes a control unit to exchange environment information with another information transfer device, and to execute deriving processing an assigned range that is assigned autonomously to its own information transfer device, based on the environment information that is kept by its own information transfer device, through a planarization search processing in which a value is evened out between its own information transfer device and other information transfer devices.

This disclosure describes systems, methods, and apparatuses related to a flexible connectivity framework. A device may cause to send a discovery request seeking a service. The device may identify a discovery response received from a computing device advertising the service. The device may cause to send a connectivity information request to the computing device. The device may identify a connectivity information response including one or more session information received from the computing device.

Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

A topology path obtaining method of a mesh network and a system configured to obtain a topology path of the mesh network are provided. In the method, a topology query packet transmitting step is performed to configure a root access point to transmit a topology query packet to a plurality of extended access points. A topology response packet transmitting step is performed to configure each of the extended access points to transmit a first topology response packet to the root access point according to the topology query packet. A topology path generating step is performed to configure the root access point to collect and process a plurality of the first topology response packets and a second topology response packet to generate the topology path. The topology path includes a connection relationship between at least one client device and one of the root access point and the extended access points.

Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

An emergency routing apparatus may include receiving a request for help from a portable device and processing the request to contact an appropriate emergency call center. The emergency call center may be determined based on location of the mobile device that is received with the request for help. If a connection can be established over a first communication link, the request for help may be transmitted to the emergency call center over the first communication link. If a connection cannot be established over the first communication link, another communication link may be used to transmit the request for help to the emergency call center. Transmitting the request for help over the other communication link may include dialing a phone number of the emergency call center and playing a message with the request for help over the other communication link.
