    摘要: A method for frequency selection in a wireless communication system, includes performing in a wireless device, receiving at least one signal at a current frequency; processing at least one data packet received via the received at least one signal to determine the presence of bit errors; characterizing the received at least one signal received at the current frequency based on the processing of the at least one data packet; classifying the current frequency based on at least the characterization of the received at least one signal; and selecting the current frequency based on the classification. At least one signal strength measurement may be performed on the received at least one signal, and the processing of the at least one data packet may be performed within a current channel classification update interval.

    摘要: Aspects of a method and system for fast and reliable channel classification in Bluetooth networks to detect and avoid channel interferers may include one or more processors that may enable performance of signal strength measurements on received Bluetooth signals at a current selected frequency. At least one data packet received via the Bluetooth signals may be processed to determine the presence of bit errors. The processor(s) may enable characterization of the Bluetooth signals at the current selected frequency based on the signal strength measurements and/or the processing of the data packets. The current selected frequency may be selected during adaptive frequency hopping based on the characterization.

    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 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.
