摘要： Aspects of the invention may comprise managing operations of BLE interfaces and/or other radio interfaces in a wireless device to mitigate interference to communication via the BLE interfaces by the other radio interfaces. Operating parameters may be communicated between the BLE interfaces and the other radio interfaces to enable mitigating the interference to the BLE interfaces, and at least some of the BLE interfaces and/or the other radio interfaces may be configured based on the communicated operating parameters. The operating parameters may comprise adaptive frequency hopping (AFH) maps that may be adjusted to prevent use of common and/or used channels. The communication device may detect energy associated with BLE communication via scan of all or some of channels used for BLE communication. BLE communication may be predicted based on monitoring of frequency bands used during BLE communication, and/or monitoring of events that may trigger and/or occur during BLE communication.

摘要： Timing vectors are used to pass execution of time-dependent operations from firmware/software to a hardware component (e.g., a state machine). These vectors may be stored as a vector table in a data memory that is accessible by both the firmware/software and the hardware component. Based on the processing being performed in the system, the firmware/software will determine that one or more operations will need to be performed at a certain time. The firmware/software stores a reference to that time and a reference to the operation(s) in a vector. The hardware component continually monitors time in the system. In addition, the hardware component will monitor each vector to determine whether the current time matches the time associated with a given vector. When there is match, the hardware component causes the operation(s) associated with the vector to be performed. The system also may perform different operations at a given time depending on the operating condition (e.g., state) of the system.

摘要： A dual-mode BLE device identifies idle intervals within Bluetooth BR/EDR traffic communications. The identified idle intervals are used by the dual-mode BLE device to concurrently perform various BLE activities. For example, advertising packet transmissions, advertising packet scanning, connection setup, and/or data packet communication may be concurrently performed within identified idle intervals within the Bluetooth BR/EDR traffic communications. Packet transmission timing, advertising interval, scan window, and/or packet size are determined based on the identified idle intervals within the Bluetooth BR/EDR traffic communications. A scan window is adjusted based on timing of expected advertising transmissions and/or advertising interval(s) for saving power. BLE packets and Bluetooth BR/EDR packets may be detected in a single advertising channel. Maximal payload size is set based on the identified idle intervals within Bluetooth BR/EDR traffic communications. As a slave, the dual-mode BLE device updates connection parameters based on the identified idle intervals within Bluetooth BR/EDR traffic communications.

摘要： Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and address the need to meet latency and throughput requirements while limiting memory footprint.

摘要： A Bluetooth low energy (BLE) device receives advertising packets from an advertising BLE device. The BLE device filters the received advertising packets utilizing hardware to search for the advertiser. If the advertiser is not found by the hardware, the packet filtering continues utilizing firmware. Device identity information, comprising non-private and/or private device identities, of preferred BLE devices is partitioned to form a different white list for the hardware, firmware, and host, respectively, to concurrently support privacy and white listing. If the advertiser is found by the hardware, the hardware sends a response to the advertiser following a successful CRC check performed in the hardware. If the advertiser is found by the firmware, the device identity information of the advertiser is inserted in the white list for the hardware. The host may be awakened based on the device configuration and/or attribute type information of the received advertising packets.

摘要： A responder endpoint establishes a reverse direction communication channel from the responder to an initiator. To that end, the responder endpoint receives a reverse direction grant indicator and determines when primary data is not ready to be sent to the initiator. In response, the responder transmits to the initiator, within a predetermined response time for establishing the reverse direction communication channel, a continuation frame comprising a continuation indicator that indicates that reverse direction communication channel should persist. In one implementation, the continuation frame includes at least one control field including the continuation indicator, but no data payload field.

摘要： Methods and systems for wireless communication are disclosed and may include controlling one or more scans of a received signal detection frequency across a frequency range and storing a magnitude of the received signal at each frequency where the magnitude exceeds a threshold level. A type of one or more signals in the received signal may be determined based on a bandwidth of the signals. A Bluetooth page/inquiry scan may be initiated if the determined type is a page/inquiry signal, and scans may be continued if the determined type may not be a page/inquiry signal. The scans may be repeated on a periodic basis and may be controlled utilizing a voltage controlled oscillator. Each of the scans may include a plurality of discrete frequency steps or a continuous frequency ramp. The controlling may include a start frequency, an end frequency and a frequency step size for the scans.
