In response to the first indication and the second indication, the network node network codes the first packet and the second packet to form a network coded packet, and wirelessly multicasts the network coded packet to the first device and the second device in a same time slot.

Abstract: Network nodes can add information to a central database (220, 300) that identifies their connections to other network nodes. The central database (220, 300) can thereby serve as a repository of information indicating connections between network nodes. When a first network node (Node 0) needs to establish a session to a second network node (Node 1), it can interrogate the central database (220, 300) to learn what existing connections, if any, can be used for the session. When existing connections provide more than one available pathway between the first and second network nodes (Node 0, Node 1), the first network node (Node 0) may select among the existing connections in response to quality of service values that are provided by the central database (220, 300) for those connections.

Abstract: In a mobile communication network, a radio node and related method for reducing a signal-to-noise-and-interference ratio (SINR) requirement for a transmission in a scheduling interval. The node estimates a frequency resource utilization in the scheduling interval and compares the estimated utilization with a first threshold.

Optionally, the node may decrease the transmit power for the scheduling interval based on the adjusted link adaptation.

The method includes depositing a first thin layer of an oxygen-free material onto a substrate. A second thin layer of a second material is deposited onto the first layer. The first layer and second layer assembly are treated under conditions so that a gas is generated in the first layer by foaming, leading to the creation of nanopores in the first layer. The second thin layer will not form a gas during this treatment and will have a sufficient density to limit or prevent the spread and/or diffusion of the gas generated in the first layer. The second thin layer may be removed.
