A system for allocating resources in a communications network includes a plurality of access points, where each access point in the plurality of access points is in communication with one or more user devices. The system also includes a central controller in communication with the plurality of access points. The central controller is configured to receive traffic information and channel information for access point&#x2014;user device links in the communications network. The central controller is also configured to receive an intensity of independent homogeneous Poisson traffic intended for the one or more user devices. The central controller is further configured to determine a joint resource allocation based at least in part on the received traffic and channel information and the intensity of independent homogeneous Poisson traffic, where the joint resource allocation is determined with an algorithm.

Radio resource management in metropolitan area networks

A system for allocating resources in a communication network includes a plurality of access points and a central controller having a transceiver and a processor. Each of the plurality of access points is configured to identify traffic information and channel information and transmit the traffic information and the channel information to the central controller. The central controller is configured to receive the traffic information and the channel information from each of the plurality of access points and to determine resource allocation recommendations based at least in part on the received traffic information and the received channel information. The central controller is also configured to transmit the resource allocation recommendations to the plurality of access points. Each of the plurality of access points is configured to allocate a resource based on the resource allocation recommendations and on local network information.

Radio resource management in large wireless networks

A system for allocating resources in a communications network includes a plurality of access points and a central controller in communication with the plurality of access points. Each access point in the plurality of access points is in communication with one or more user devices. The central controller is configured to receive traffic information and channel information for access point&#x2014;user device links in the communications network. The central controller is also configured to determine a joint resource allocation based at least in part on the received traffic and channel information and at least in part on an algorithm. The central controller is further configured to transmit the joint resource allocation to the plurality of access points, where the joint resource allocation comprises spectrum allocation, user association, and power allocation.

A node in a wireless network includes a memory, transceiver, and processor operatively coupled to one another. The memory stores a signature of the node. The transceiver is configured to transmit, during an initial frame, the signature to one or more neighboring nodes, and receive, during the initial frame, a first signal that includes one or more signatures of the one or more neighboring nodes. The transceiver is also configured to transmit, during a repetition frame, a scrambled waveform of the first signal received during the initial frame, and receive, during the repetition frame, a second signal that includes a retransmission of signals received by the one or more neighboring nodes during the initial frame. The processor is configured to determine a distance from the node to each of the one or more neighboring nodes based at least in part on the first signal and the second signal.

System and method for multi-user two-way ranging

A half-duplex wireless network device is structured to transmit and receive information over a unique pattern of one or more transmission slots and one or more reception slots within each of a sequence of communication frames to accomplish virtual full-duplex communication.

Virtual full duplex network communications

A system including a number of wireless communication nodes spaced apart from one another. The nodes are structured to transmit and receive unique signatures. A neighborhood of nodes may be discovered based on the unique signatures.
