Abstract: An approach is disclosed for synchronization of frequency and/or phase in a full duplex network. The method may comprise sending a timing beacon over a single full duplex radio channel from a timing master to a timing slave; receiving the timing beacon over the single full duplex radio channel at the timing slave; sending a retransmitted beacon over the single full duplex radio channel from the timing slave to the timing master; and sending a delta of the timing beacon and the retransmitted beacon from the timing master to the timing slave. The beacon may contain a timestamp. The retransmitted beacon may include a delay calculation. A hybrid analog/digital self-interference cancellation system may be used at the timing master or the timing slave. The method may also include simultaneously sending and receiving the synchronization information over the single full duplex radio channel.

Abstract: Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.

Abstract: This application discloses methods for creating self-organizing networks implemented on heterogeneous mesh networks. The self-organizing networks can include a computing cloud component coupled to the heterogeneous mesh network. In the methods and computer-readable mediums disclosed herein, a processor determines if a user equipment (UE) should hand over its service from a base station to a multi-radio access technology (RAT) node, based on heuristics including one or more of: a distance traveled over a time T1, an average speed over a time T2, a destination stored in internal memory within the UE, a speed limit measurement for a nearby road, a possible direction in which the UE could travel, a signal strength measurement for a servicing base station, and a signal strength measurement for the multi-RAT node. A position profile may be used to predict a future location of the UE.

Abstract: A centrally controlled dynamic frequency selection (DFS) mechanism is defined that uses a historical analytical database to define DFS hop patterns, which allows for a better probability of picking a non-interfering channel but also meets the performance requirements of the mesh and satisfying the timing constraints of DFS. A method for performing dynamic frequency selection (DFS) is disclosed, comprising: receiving, at a gateway, measurement reports from a radio access node regarding observed utilization of a 5 GHz radio frequency band shared with a plurality of radio access nodes; determining, based on the received measurement reports, a frequency hop pattern at the gateway; and sending the frequency hop pattern from the gateway to each of the plurality of radio access nodes, thereby enabling compliance with DFS regulations using a centralized gateway.
