    Abstract: Aspects relate to wireless communication at a wireless communication device. The wireless communication device may include a transmitter configured to communicate using a first communication protocol, a receiver configured to communicate using a second communication protocol, different from the first communication protocol, a first antenna coupled to the transmitter, a second antenna coupled to the receiver and physically separated from the first antenna by a variable distance. The wireless communication device transmits, via the first antenna, a first transmission within a first frequency range, and receives via the second antenna, a second transmission within a second frequency range that overlaps the first frequency range. To receive the second transmission, the device may perform a radio frequency coexistence mitigation procedure based on the variable distance between the first antenna and the second antenna in response to detection of a concurrency in time between the first transmission and the second transmission.

    Abstract: Systems, methods, and apparatus are described that provide for communicating coexistence messages over a multi-drop serial bus. A method performed at a device coupled to a serial bus includes receiving first coexistence information directed to a first device coupled to the serial bus, generating a first coexistence message representative of the first coexistence information, converting the first coexistence message to obtain a first datagram including the first coexistence information, and transmitting the first datagram to the first device over the serial bus. The first coexistence message may be configured for communication through a point-to-point data link. The first datagram may be configured according to a first protocol associated with the serial bus.

    Abstract: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. Each device can contend for control of a communications link by driving a data signal to a first voltage level. If the data signal or a clock signal changes before an arbitration time period has elapsed, one or more devices yield control of the communications link to another contender. The arbitration time period for each contender is different and indicates a priority of the message to be transmitted. A shorter arbitration time period indicates higher priority. Arbitration may commence after clock and data signals of the communications link remain in an idle or other predefined state for a minimum idle time. The minimum idle time may be different for different nodes and may be shorter for high priority messages or nodes.

    Abstract translation: 描述了促进数据传输的系统，方法和装置，特别是在电子设备内的两个设备之间。 每个设备可以通过将数据信号驱动到第一电压电平来争取控制通信链路。 如果在仲裁时间段过去之前数据信号或时钟信号改变，则一个或多个设备产生对另一个竞争者的通信链路的控制。 每个竞争者的仲裁时间段不同，表示要发送的消息的优先级。 较短的仲裁时间段表示优先级较高。 仲裁可以在通信链路的时钟和数据信号保持在空闲或其他预定义状态中达到最小空闲时间之后开始。 不同节点的最小空闲时间可能不同，对于高优先级消息或节点可能较短。

    Abstract: Methods, systems, and devices are described for wireless communication. A wireless device may identify an upcoming interference period, determine a receive end time based on when the interference period will begin to disrupt incoming messages, and transmit a scheduling outlook message to a transmitter to schedule around the interference in response to receiving a packet (request-to-send (RTS) or data). The wireless device may hash a receiver address (RA) associated with the packet exchange message such as a clear-to-send message or a block acknowledgement to make room for the scheduling outlook message. An example scheduling outlook field (in the place of the full RA field) may include a shortened RA, a number of supported spatial streams, a supported bandwidth, a set of tone allocation units (TAUs), a receive end time (or receive duration), and an interference level.

    Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device determines when a first transceiver chain of the wireless device is to receive a first data signal. The wireless device then transmits a second data signal via a second transceiver chain of the wireless device based at least in part on the determination. The wireless device further suspends the transmission of the second data signal in response to the determination that the first transceiver chain is to receive the first data signal.
