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 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： A technique to provide frequency offset estimation for packets transmitted during a service period allocated strictly for designated source and destination devices. The destination device obtains coarse and fine frequency offset estimation from the short and long preambles. A residual frequency offset is tracked for the data blocks and combined with the coarse and fine frequency offset to obtain a total frequency offset to apply to the data blocks. The total frequency offset value at the end of the first packet is saved and, instead of again estimating the coarse and fine frequency offset values with the short and long preambles of the second packet, the saved total frequency offset value is used as the initialization value to add to the residual frequency offset in the second packet. The saved offset value at the end of each packet becomes the initialization value for the subsequent packet.

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： 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： Methods and systems for wireless communication are disclosed and may include sweeping a signal detection frequency one or more times across a plurality of steps in a frequency range. The measured signal strength at each step may be compared to a threshold, and a status may be stored, which may depend on the presence of a measured signal strength above threshold. The detection frequency may be swept utilizing a voltage controlled oscillator, which may be tuned via a control voltage and/or calibration capacitors. Steps may be skipped when a measured signal strength may be greater than the threshold, and may occur after multiple above threshold measurements. The steps may have variable frequency width, and the range may include the Bluetooth band from 2.40 GHz to 2.48 GHz. The frequency may be swept over a subset of the Bluetooth band, and may be swept on a periodic basis.
