  • System, method and apparatus for managing co-channel interference
    Patent number: 10439743
    Abstract: A system, method, and apparatus for managing interference are presented. The interference may be between i) a fixed wireless link, FL, formed by a first FL node and a second FL node which communicate at a frequency f1 and ii) a radio access network, RAN, node. The method may comprise the first FL node monitoring radio link quality, QL, of fixed wireless link signals at f1. The first FL node may determine whether QL is worse than a predetermined QL threshold. If QL is worse than the predetermined QL threshold, the first FL node may measure, during a silent period, how much one or more signals transmitted from the RAN node 108 interferes with the first FL node at the f1. The first FL node may transmit, to an interference mitigation controller, interference measurement information which indicates how much the RAN node interferes with the first FL node at f1.

  • Sidelink Assisted Cooperative Listen-Before-Talk
    Publication number: 20190261413
    Abstract: Systems and methods are disclosed herein that relate to the use of a Device-to-Device (D2D) sidelink, e.g., in a licensed spectrum, to assist with clear channel assessment in an unlicensed spectrum. In doing so, the hidden node problem and/or the exposed node problem can be mitigated. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises performing a sidelink-assisted clear channel assessment (SLA-CCA) procedure to determine whether to transmit on an unlicensed channel. The SLA-CCA procedure is a Clear Channel Assessment (CCA) procedure that is assisted by information received by the wireless device from one or more other wireless devices over a D2D sidelink in a licensed spectrum. The method further comprises, upon determining to transmit on the unlicensed channel as a result of performing the SLA-CCA procedure, transmitting a transmission on the unlicensed channel.

    Patent number: 10123251
    Abstract: Methods, apparatuses, and computer program products for communicating channel assessment, channel information, and routing information between a spectrum controller and radio resource manager. A spectrum controller obtains channel information and classifies a number of radio channels of a network as available, partially available, or unavailable. The availability information is sent to a radio resource manager, which can use the information to determine a routing solution. The radio resource manager can request that the spectrum controller perform an access negotiation for a partially available channel. Based on the result of the negotiation, the radio resource manager may re-route information in the network.
