  • Patent number: 10708934
    Abstract: Methods, systems, computer-readable media, and apparatuses for managing coexistence of a satellite positioning system (SPS) receiver with one or more transceivers are presented. In some embodiments, a device determines whether a first transceiver of the one or more transceivers in accordance with a first Radio Access Technology (RAT) is able to transmit a packet via a first frequency band within a time period based at least on a first coexistence rule. The first coexistence rule corresponds to an impact on the SPS receiver by operation of at least the first RAT on the at least the first transceiver. The device transmits the packet via a second frequency band in accordance with a second RAT based on the determination that the first transceiver in accordance with the first RAT is not able to transmit the packet via a first frequency band within the time period.

  • Patent number: 10070474
    Abstract: The disclosure generally relates to negotiating a best device-to-device (D2D) radio access technology (RAT) to use in a D2D connection. In particular, two wireless devices that correspond to potential D2D peers may exchange respective radio configurations according to a D2D coexistence protocol to mutually negotiate the “best” RAT to use in the D2D connection, wherein the exchanged radio configurations may comprise at least radio capabilities and coexistence states (e.g., in-device and/or cross-device coexistence states) associated with the respective wireless devices. The potential D2D peers may then negotiate one or more compatible RATs that are available to use in the D2D connection according to at least the radio capabilities and the in-device and cross-device coexistence states exchanged therebetween. As such, the two wireless devices may then establish one or more D2D connections using the negotiated compatible RAT(s).

  • Patent number: 9877308
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a broadcast multimedia receiver device. The apparatus detects a signal causing interference at a first radio of the receiver device. The first radio is configured to receive broadcast multimedia transmissions. The apparatus determines a RAT associated with an aggressor entity transmitting the signal. The aggressor entity is physically remote from the receiver device. The apparatus determines a mitigation action to mitigate the interference caused by the signal at the first radio. The apparatus transmits, at a second radio of the receiver device, a control message to the aggressor entity. The control message instructs the aggressor entity to implement the mitigation action. The second radio is configured to communicate with the aggressor entity using at least one RAT or a wired interface.

  • Patent number: 9820158
    Abstract: A user equipment (UE) may mitigate interference on the user equipment with two or more radios. In some instances, the UE may determine when communications of the two or more radios experience interference, in which two radios of the two or more radios operate with the same radio access technology. Further, the UE may alter an operating frequency of a first radio of the two radios to mitigate the interference.

  • Patent number: 9749925
    Abstract: Various arrangements are presented for managing co-existence of a global navigation satellite system (GNSS) receiver with one or more transceivers. A coexistence manager may obtain one or more parameters associated with a first transceiver of the one or more transceivers operating in accordance with a first radio access technology (RAT) and corresponding to an operating event. The first transceiver may be capable of operating in accordance with one or more RATs. The coexistence manager may further determine that the one or more parameters impacts an operation of the GNSS receiver and exceeds a predefined threshold and instruct the first transceiver to perform at least one of selecting a second RAT, changing the one or more parameters or any combination thereof to transmit at least a first portion of a data corresponding to the operating event based on the determination that the one or more parameters impacts the operation of the GNSS receiver.

  • Patent number: 9736875
    Abstract: Direct device-to-device (D2D) communications may be coordinated to reduce interference to the sets of radios involved in the individual device-to-base station or device-to-access point communications for the individual devices of the D2D communications. Coexistence management plans for the individual devices may be used to determine a D2D coexistence management plan to reduce interference among the many communications, both for the D2D communications and for non-D2D communications of the individual devices.

  • Patent number: 9632184
    Abstract: Various arrangements are presented for managing coexistence of a global navigation satellite system (GNSS) receiver with a radio access technology (RAT) transceiver. A coexistence manager may receive an indication of a characteristic of a RAT transceiver for a scheduled operating event. Based on the characteristic of the RAT transceiver for the operating event, the coexistence manager may select a space vehicle of a GNSS to use for a location determination by the GNSS receiver. The GNSS receiver may then receive a signal from the space vehicle of the GNSS during the operating event of the RAT transceiver. Location determination using the signal received from the space vehicle received during the operating event of the RAT transceiver may then occur.
