摘要： Systems, methods, and apparatus are described that enable a serial bus to be operated in multiple modes that employ additional wires for communicating data such that the bus width may be dynamically extended to improve bandwidth and/or throughput. One method includes transmitting a set of frames or sequences of symbols configured to carry up to a maximum number of data bytes over the serial bus, transmitting control signaling over a first data lane and the clock lane after the set of frames or sequences of symbols has been transmitted, and transmitting a first signal over a second data lane while transmitting the control signaling that may indicate whether the set of frames or sequences of symbols includes padding. The first signal may indicate a number of valid bytes or words in the set of frames or sequences of symbols.

摘要： Systems, methods, and apparatus for serial bus arbitration are described. A method for arbitrating access to a serial bus includes providing a clock signal on a first line of the serial bus, configuring a line driver coupled to a second line of the serial bus for open-drain operation, transmitting an address header through the line driver in accordance with timing provided by the clock signal, detecting that the second line is driven low in a bit interval corresponding to the at least one most-significant bit, configuring the line driver for push-pull operation after detecting that the second line has been driven low, and increasing rate at which clock pulses are provided in the clock signal after detecting that the second line has been driven low. The address header may include at least one most-significant bit that has a zero-value when a high-priority device is addressed.

摘要： Systems, methods, and apparatus are described that enable a serial bus to be operated in one or more modes that employ additional wires for communicating data. A method for transmitting data over a serial bus includes receiving from a first line of the serial bus a clock signal used for timing transmission of data on a second line of the serial bus, activating a driver after the first line has transitioned from a first signaling state to a second signaling state while the data is being transmitted on the second line, driving the first line to the first signaling state to transmit a first bit of data when the first bit of data has a first value, and refraining from driving the first line to the first signaling state to transmit a first bit of data when the first bit of data has a second value.

摘要： Systems, methods, and apparatus for communicating datagrams over a serial communication link are provided. A transmitting device generates an address field in a datagram, sets a value of at least one bit in the address field to indicate a number of bytes of data associated with a data frame of the datagram, generates the data frame in the datagram, the data frame including the number of bytes of data, and sends the datagram to a receiving device. A receiving device receives a datagram from a transmitting device, decodes an address field of the datagram to detect a number of bytes of data included in a data frame of the datagram based on a value of at least one bit in the address field, and decodes the data frame to recover the detected number of bytes of data.

摘要： Techniques for acquiring Global Navigation Satellite System (GNSS) signals at a mobile device are provided. An example process according to these techniques includes receiving sensor data from at least one sensor of the mobile device, determining one or more blocked zones based on the sensor data in which at least a portion of signals from at least one space vehicle (SV) are blocked by an obstruction, selecting one or more SVs from SV information based on the one or more blocked zones, and attempting to acquire signals from the one or more SVs.

摘要： 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).

摘要： A user equipment (UE) may flexibly or dynamically access one or more network operators via one or more subscriber identity modules (SIMs) (or virtual SIMs) in the mobile device. Each SIM provides authentication/access to a single network operator, and multiple SIMs will therefore enable multiple network operator accesses. The authentication may be based on one or more physical SIMs and/or virtual SIMs. A connectivity engine in the UE allows for dynamic selection and/or authentication of network operators, e.g., wireless/mobile network operators or carriers, and their corresponding radio access technologies (RATs).
