In some aspects, the disclosure is directed to methods and systems for providing a hybrid low power, high bandwidth media transport protocol between media sinks and media sources by splitting control and synchronization commands to a low power communication interface, and media data to a high bandwidth unidirectional communication interface. Media sinks need not transmit via the high bandwidth unidirectional communication interface, reducing power consumption, which may be particularly beneficial for small devices with limited battery capacity such as wireless earbuds.

Low power high definition wireless media transport

A device implementing unified coordination of wireless communications over multiple physical layers may include a MAC module communicatively coupled to first and second physical layer modules that are each configured to communicate with another device over first and second physical wireless channels, respectively. The MAC module may be configured to provide data to the first physical layer module for transmission to the another device over the first physical wireless channel, where the first physical wireless channel is associated with a first link parameter. The MAC module may be further configured to facilitate initializing the second physical wireless channel based at least in part on the first link parameter of the first physical wireless channel, and after initialization of the second physical wireless channel, provide second data to the second physical layer module for transmission to the another device over the second physical wireless channel.

Unified coordination of multiple physical layer devices

Various methods and systems are provided for space, frequency and time domain coexistence of RF signals. In one example, among others, a communication device includes a coexistence manager capable of monitoring operating conditions of a cellular modem and a coexistence assistant capable of monitoring operating conditions of a wireless connectivity unit. The coexistence manager is capable of modifying operation of the modem and/or unit based on an operating condition change. In another example, a method includes detecting a change in antenna isolation and/or operating temperature of a FE filter, determining filtering characteristics of the FE filter based at least in part upon the change, and modifying communications of coexisting communication protocols based at least in part upon the filtering characteristics. In another example, a TX/RX configuration for coexisting communication protocols is determined and communications in a protocol is modified based at least in part upon the TX/RX configuration.

Dynamic space, frequency and time domain coexistence

A device implementing unified media access control (MAC) for multiple physical layer devices may include at least one processor communicatively coupled to first and second physical layer modules that are configured to communicate with another device over first and second wireless channels, respectively. The at least one processor may be configured to receive one or more data items to be transmitted to the another device and to select at least one of the first or second physical layer modules for transmission of the one or more data items based at least in part on a first condition of the first physical wireless channel and a condition of the second physical wireless channel. The at least one processor may be further configured to provide the one or more data items to the selected at least one of the first or second physical layer modules for transmission to the another device.

Unified media access control (MAC) for multiple physical layer devices

Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.

Systems and methods for enabling coexistence of multiple wireless components operating in the same frequency band

Various methods and systems are provided for time domain coexistence of RF signals. In one example, among others, a method includes obtaining access to a WLAN channel during a free period of a coexisting cellular connection, providing a RDG to allow another device to transmit for a duration corresponding to at least a portion of a TXOP, and receiving a transmission during the duration. In another example, a method includes obtaining access to a WLAN channel during a transmission period of a coexisting cellular connection and providing a protection frame to defer transmissions from another device for a duration corresponding to at least a portion of a TXOP. In another example, a method includes determining a shift of a BT transaction based at least in part upon a schedule of cellular communications and shifting at least a portion of the BT transaction based upon the determined shift.

Time domain coexistence of RF signals

A device implementing unified media access control (MAC) for multiple physical layer devices may include a MAC module communicatively coupled to first and second physical layer modules that are configured to communicate with another device over first and second physical wireless channels, respectively. The MAC module may be configured to receive one or more data items to be transmitted to the another device and to select at least one of the first or second physical layer modules for transmission of the one or more data items based at least in part on a first wireless link quality of the first physical wireless channel and a second wireless link quality of the second physical wireless channel. The MAC module may be further configured to provide the one or more data items to the selected at least one of the first or second physical layer modules for transmission to another device.

Determining a mobile device's location, includes receiving, by the mobile device, a first packet from a first access point and generating a first time-stamp representing the first packet's arrival time; receiving, by the mobile device, a second packet from a second access point and generating a second time-stamp representing the second packet's arrival time; using these to determine the difference between the arrival times of the first and second packet at the mobile device; receiving, by the mobile device, first information representative of the first packet transmission time and second information representative of the second packet transmission time, the first and second information used to find the interval between the transmission of the first and second packets from the first and second access points respectively; determining, by the mobile device, the difference between the flight-times of the first and second packets to the mobile device; and determining, by the mobile device, the difference between the distance from itself to the first access point, and the distance from itself to the second access point and doing this over sufficient pairs of access points to find its location.

Determination of location of a mobile device having time-stamping capability

A method includes determining that an antenna shared between a Bluetooth transceiver and a WLAN transceiver is available to the WLAN transceiver based on an activity signal associated with the Bluetooth transceiver. Access to the shared antenna is provided to the WLAN transceiver based on the determination, and the WLAN transceiver is configured to use diversity in transacting WLAN signals via a plurality of antennas, including the shared antenna. Access to the shared antenna is transferred from the WLAN transceiver to the Bluetooth transceiver based on the activity signal.
