A depth and distance-based single-path routing method, in which location information of nodes in network is gathered after initialization is completed, and a location table of whole-network nodes maintained by the sink node is generated. The update mechanism of the uplink Location frame is switched to a unicast triggering update mechanism to execute a depth and energy-based uplink routing algorithm. For a downlink control packet arriving at a specified ID, location information of a node is obtained through the location table to execute a distance and energy-based downlink routing policy. The distance and energy-based downlink routing policy for a downlink control packet arriving at a specified location and a downlink control packet arriving at the specified ID is executed, and a routing recovery algorithm is executed when an “open area” occurs.

A method, system and apparatus are disclosed. In one or more embodiments, a network node configured to communicate with a wireless device (WD) is provided. The network node configured to, and/or including a radio interface and/or including processing circuitry configured to: receive information indicating a timing offset (T′.sub.Δ), determine transmission timing for downlink transmission based on the timing offset (T′.sub.Δ) and at least one estimated timing value, and perform downlink transmission based on the determine transmission timing.

There is provided systems and methods for the grouping of UEs, such that UEs can share a UE group context or share a PDU session context or both. In this manner, network resource usage, with respect to UE context and PDU session context management, can be mitigated.

Described herein includes a mobile terminal, a data transmission method and a related product used in a mobile terminal. The method comprises: in response to detecting a starting request for a preset application, starting an enhanced signal transceiver function of a mobile terminal; performing scanning and connecting operations and establish an Ad Hoc network with another device, wherein a distance between the another device and the mobile terminal is less than or equal to a preset distance; and performing transmission of target data in the Ad Hoc network. The embodiments of the present disclosure are conducive to enlarging an application scope of a communication function of a local area network for mobile terminals, meeting various requirements of specific scenarios such as the absence of a mobile network, and expanding functionality and applicability.

Provided is a process that includes obtaining a directed acyclic graph describing a plurality wireless connections between a plurality of downstream nodes forming a multi-path route to an Internet connected wireless transceiver; determining an encoding kernel specifying transformations to be performed by the plurality of downstream nodes on data received from upstream nodes; transmitting at least part of the encoding kernel to at least some of the downstream nodes; and transmitting data from a data source to a downstream node in the directed acyclic graph specified by the encoding kernel such that the data is conveyed through the multi-hop, multi-path route to the Internet connected wireless transceiver.

The disclosure provides for a system that includes a network controller configured to determine a network configuration of a network and cause the network to implement the network configuration. The network controller may be configured to determine that an overall link bandwidth for a particular geographic area is less than a set bandwidth amount based on link bandwidth information for possible links directly connected to the particular geographic area. Based on a difference between the overall link bandwidth and the set bandwidth amount, the network controller may be configured to determine additional links to connect to the particular geographic area in a given network configuration of the network. The network controller may then send instructions to the plurality of nodes of the network to cause the plurality of nodes to implement the given network configuration and transmit client data at the given point in time.

Systems and methods manage split bearer selection in a multi-RAT dual connectivity environment. A first wireless station receives, from a first device, a first signal measurement for the first wireless station and a second signal measurement for a second wireless station. The first wireless station determines that the second signal measurement indicates that a split bearer for the first device can be supported by the second wireless station and identifies, based on the first signal measurement, a distance category for the first device relative to the first wireless station. The first wireless station determines, based on the second signal measurement, whether the second wireless station supports a sustainable split bearer and initiates a split bearer for the first device using the second wireless station, in response to determining that the second wireless station supports the sustainable split bearer.

A node maps end-user bearers to backhaul bearers in an adaptation layer. The node maps a plurality of end-user bearers to backhaul bearers in consideration of QoS classes for the end-user bearers and a distance from the node to a destination relay node for each of the plurality of end-user bearers, such that at least one of the backhaul bearers carries end-user bearers with different QoS classes and different distances to the destination relay node. The distance from the node to the destination relay node for at least one of the end-user bearers may be considered in terms of a number of remaining hops from the node to the destination relay node and/or in terms of an estimated end-to-end delay from the node to the destination relay node.
