Patent number: 10708934Abstract: 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.Type: GrantFiled: July 25, 2018Date of Patent: July 7, 2020Assignee: QUALCOMM IncorporatedInventor: George Chrisikos

Patent number: 10070474Abstract: 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).Type: GrantFiled: July 14, 2017Date of Patent: September 4, 2018Assignee: QUALCOMM IncorporatedInventors: Richard Dominic Wietfeldt, George Chrisikos

Patent number: 9877308Abstract: 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.Type: GrantFiled: August 11, 2015Date of Patent: January 23, 2018Assignee: QUALCOMM IncorporatedInventors: George Chrisikos, Richard Wietfeldt
