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 mobile device such as a Bluetooth low energy (BLE) device detects out-of-band blocking signals and manages packet transmission in associated BLE link layer connections based on the detected out-of-band blocking signals. The BLE device is operable to measure out-of-band RSSI to detect out-of-band transmission interferences. The BLE device compares the measured out-of-band RSSI with an out-of-band energy profile such as a LTE energy profile or a WiMAX energy profile to determine the out-of-band blocking signals indicating cadence or periodic out-of-band traffic activities. A remote BLE deice (advertiser) aperiodically or periodically transmits an advertising packet to the BLE device for a specific link layer connection. If not connected within a determined time period, the remote BLE device (advertiser) reduces transmission power for transmitting the advertising packet. The BLE device receives the advertising packet and sends a connection request packet to the remote BLE device (advertiser).

摘要： Methods and systems for collaborative coexistence of Bluetooth and WiMax are disclosed. Aspects of one method may include a packet traffic arbiter (PTA) in a mobile terminal that arbitrates among requests to transmit from one or more communication devices collocated in the mobile terminal. The communication devices may comprise, for example, a WLAN communication device, a WiMax communication device, and/or a Bluetooth communication device. The arbitration may be based on, for example, whether a packet will be received by one of the plurality of collocated communication devices at a time of transmission of the present data packet and/or a priority for data to be transmitted. An exemplary scenario may be where a Bluetooth headset may be used for communication over a WiMax voice connection. One arbitration method may comprise allowing the WiMax packet to be transmitted, and replacing the received Bluetooth packet with data indicating silence. Another method may comprise not allowing transmission of the present WiMax packet. Rather, the present WiMax packet and a subsequent WiMax packet may e transmitted at the next transmission period.

摘要： Aspects of a method and system for a shared antenna control using the output of a voice activity detector are provided. A single radio chip for use within a wireless device may handle communication of a Bluetooth (BT) and a Wireless Local Area Network (WLAN) protocol via a single antenna. Simultaneous reception via BT and WLAN channels may be enabled. The single radio chip may enable detection of voice activity in the BT channel and may reduce the BT transmission priority level some time after the voice activity indicates that the BT channel is not transmitting voice information to enable error concealment. Voice activity detection may be based on PCM samples in the BT channel. The single radio chip may transmit an ACK signal to an access point after the BT transmission priority level is reduced.
