  • Patent number: 9480054
    Abstract: Methods and apparatus for mitigating interference which are well suited for high density deployments of small base stations are described. In various embodiments, control channel resources are intentionally not fully utilized. A control channel resource utilization parameter is set, e.g., as a function of interference, to limit base station average transmission power used for transmitting signals on control channel resources. By controlling utilization of control channel resources, e.g., by limiting resource utilization to result in a lower than possible, e.g., permitted, average transmission power level, the base station constrains the amount of interference to other nearby devices, e.g., base stations and UE devices. Nearby base stations operate and/or are controlled in a similar manner. As a result, nearby base stations which are causing interference to one another will reduce inter-base station interference.

  • Publication number: 20160262059
    Abstract: Methods and apparatus for supporting efficient transitioning of a UE device from a source to destination base station are described. Various embodiments are well suited for use in an environment in where there may be PCI confusion. The handover mechanism is used to: (i) deliver context transfer information corresponding to the UE to one or more potential target base stations and to be available for use by other base stations and (ii) to force an initial handover attempt to fail via the use of intentionally faulty radio resource information. Following the initial handover attempt failure, the UE establishes a successful connection with the destination base station using valid radio resource information which was recovered via a received wireless broadcast signal.

    Abstract: A method for managing uplink signal quality at a radio node and at a macrocell and/or external cell, includes determining a first transmit power associated with a radio node of a small-cell radio access network and a second transmit power associated with a macrocell and/or an external cell. A desense value associated with an uplink of the radio node of the small-cell radio access network is provided, which enables balancing of a first signal to noise-plus-interference ratio associated with an uplink of the small-cell radio access network and a second signal to noise-plus-interference ratio associated with an uplink of the macrocell and/or external cell in relation to a downlink of the radio node, thereby managing uplink signal quality at the radio node of the small-cell radio access network and at the macrocell and/or external cell.
