Systems and methods for determining and reducing drift in inertial navigation systems (INS). One method includes receiving images and drifted positions associated with a plurality of INS. The method includes detecting, from the plurality of images, a plurality of objects associated with the plurality of INS. The method includes determining, relative positions for the objects. The method includes generating a plurality of avatars, each having a virtual position, and associating each of the plurality of objects to one of the plurality of avatars. The method includes, for each of the INS, calculating a relative drift based on the relative position of the object and the drifted position of the INS. The method includes calculating a drift correction factor for at least one of the INS, and transmitting the drift correction factor to an electronic device associated with the INS.

Determining and reducing inertial navigation system drift

An inter-device interference mitigation system, method, and device. The device includes a first transceiver, a second transceiver, and an electronic processor. The electronic processor is configured to receive an interference policy and receive information from a second electronic communications device to determine an interference potential. The electronic processor compares the interference potential to a predetermined interference threshold. When the interference potential exceeds the predetermined interference threshold, the electronic processor performs at least one action selected from the group consisting of adjusting a power output of the first transceiver, generating a user notice including instructions to move or adjust an operation of either one or both of the electronic communications device and the second electronic communications device, affecting an operation of an application present on either one or both of the electronic communications devices, and modifying a transmission of either one or both of the electronic communications devices.

A method for reducing radiofrequency interference in a mobile communications device. The method includes receiving, by a first mobile communications device, a frequency message including a frequency band of a second mobile communications device. The method further includes determining, by an electronic processor of the first mobile communications device, whether the frequency band of the second mobile communications device conflicts with an operating frequency band of the first mobile communications device. The method further includes generating, by the electronic processor, an interference message, including a proposed mitigation action, when the frequency band conflicts with the operating frequency band. The frequency band and the operating frequency band each may be a long-term evolution frequency band or a land-mobile radio frequency band.

A method, apparatus, and system are provided for mitigating interference between two communication sessions based on a determined geographical proximity of two mobile devices (MDs) to each other. In one embodiment, a geographical proximity is determined of a first MD, engaged in a first communication session, to a second MD, engaged in a second communication session. Based on the determined geographical proximity, one of the two communication sessions is transferred to the other MD so that both communication sessions are resident at, and can be controlled by, a same MD. In other embodiments, wherein a first MD is engaged in two communication sessions, one of the two communication sessions may be transferred to a second MD that is sufficiently geographically distant from the first MD or the first MD may use a geographically distant remote wireless device as an uplink and downlink relay device for one of the communication sessions.

Disclosed herein are methods and systems for scheduling transmission of uplink communication. One embodiment takes the form of a process carried out by a first-radio-access-network-(RAN) entity in a first RAN, where the first RAN has a first-RAN uplink that is time-synchronized with a second-RAN uplink of a second RAN. The first-RAN entity detects an uplink-scheduling event associated with a mobile radio, and the first-RAN entity also identifies a second-RAN-uplink-transmission time slot for the mobile radio. The first-RAN entity schedules the mobile radio to transmit first-RAN-uplink communication, which is associated with the detected uplink-scheduling event, during a first-RAN-uplink time slot that does not overlap the identified second-RAN-uplink-transmission time slot.

A Long Term Evolution (LTE) Concentrator and Distributor system and method extends geographical coverage while minimizing Evolved Node B (eNB) deployments. The system and method use a distributed array of Wide Band Receiver Transmitter (WBRT) devices (i.e., RF Heads, RFH, including antennas) connected via wide-band links to a central standard LTE eNB through a novel LTE Concentrator-Distributor (LTE-CD) which is an uplink (smart optimal) concentrator and downlink simulcast distributor. The eNB downlink signal (baseband or modulated RF) is distributed in synchronization (simulcast) through the LTE-CD to all WBRTs for downlink simulcast transmission to all UEs in the coverage area. The WBRTs receive uplink signals from user equipment, UE, devices in a coverage area, send the uplink signals (baseband or modulated RF) to the LTE-CD which optimally combines all received signals into one best uplink signal that is sent (in baseband or modulated RF) to the eNB.

Methods for inter-mixer communication enable a 'self-formed' cascaded mixer node tree topology. One method enables inter-mixer node signaling and includes first selecting a plurality of media flow payloads at a first cascaded mixer node. A set of conference payloads are generated and each include the media flow payloads from the plurality of media flow payloads that are part of the same conference call, an identifier for the conference call, and a node identifier for each media flow in the conference call. For each media flow in the conference call, each conference payload further identifies whether the first cascaded mixer node is a root node or a leaf node. The set of conference payloads are bundled into a single packet and sent to a second cascaded mixer node. Another method enables the 'self-forming' of the mixer node tree topology. Yet another method enables active talker identification within the &#x201c;self-formed&#x201d; tree topology.
