Abstract: As many applications, such as wireless headsets used with cellular phones, require mostly error free data to accurately reproduce a telephone conversation, uncorrected erroneous data packets may impact a perceived quality of a given application. The error correction techniques of the present disclosure promote error-correction in communication systems that lack FEC with respect to one or more portions of a data packet. The techniques therefore provide error correction for the entire packet, including those portions not protected by any imbedded error correction mechanism. As a result, data communications over noisy communication mediums may be improved as the techniques may reduce bit error rates, and increase the sensitivity of the receiving device such that the transmission power of a data packet may be reduced. For voice packets or other streaming data packets, the techniques promote improved audio quality over systems that do not employ the techniques described in the present disclosure.

Abstract: The apparatus may establish a non-proprietary link layer connection with a second device. The apparatus may determine if a first set of empty non-proprietary link layer PDUs are exchanged with the second device via one or more channels during a non-proprietary link layer connection event. The apparatus may exchange proprietary establishment PDUs with the second device during at least one proprietary link establishment event via the one or more channels when it is determined that the first set of empty non-proprietary link layer PDUs are exchanged with the second device via the one or more channels. The apparatus may establish a proprietary link layer connection with the second device when it is determined that a sequence of the proprietary establishment PDUs have been exchanged with the second device. The apparatus may communicate with the second device via the proprietary link layer connection.

Abstract: Using the modulation scheme and/or coding techniques of traditional BLE may limit not only the data rate, but also limit the amount that the transmit power of a BLE air interface packet can be reduced due to receiver sensitivity. Namely, the lowest signal power level from which a receiving device may obtain information without meeting a BER threshold may limit the amount that the transmit power at the transmitter side can be reduced. There exists a need to transmit a BLE air interface packet using a modulation rate that is greater than 1 Mbps or 2 Mbps, enables a further reduction in transmit power, and/or enables an increase in receiver sensitivity. The present disclosure provides a solution by applying a coding technique and a PSK modulation scheme to a BLE air interface packet that increases data rate and reduces the sensitivity of the receiving device as compared to traditional BLE.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may establish a non-proprietary short-range link layer connection with a second device. The apparatus may establish a proprietary link layer connection with the second device. The apparatus may determine a duration of a previous non-proprietary link layer connection event. The apparatus may determine a number of proprietary link layer control PDUs to be exchanged during a proprietary connection event based at least in part on the duration of the previous non-proprietary link layer connection event and a start time of a subsequent non-proprietary link layer connection event. The apparatus may perform a proprietary control procedure by exchanging the number of proprietary link layer PDUs with the second device during the proprietary connection event.

Abstract: According to various aspects, techniques to enable implicit and/or explicit transmit (Tx) beamforming in a wireless personal area network are provided. In particular, the implicit transmit beamforming may be enabled during certain events, frames, and/or other conditions when a channel between a beamformer and a beamformee is reciprocal (i.e., packets are received and transmitted on the same frequency). In such cases, the beamformer may estimate channel state information (CSI) based on a packet received from the beamformee and use the estimated CSI to steer a beam in a direction towards the beamformee. In use cases that implement explicit transmit beamforming, the beamformee may estimate the CSI based on a packet received from the beamformer and provide the estimated CSI to the beamformer, which may then use the estimated CSI received from the beamformee to steer a beam in a direction towards the beamformee.

The apparatus may a first LMP encapsulated header PDU that includes a first QLMP feature request opcode to the second device when it is determined that one or more of the link layer identification, the version number, or the sub-version number included in the LMP version response PDU are associated with the recognized QLM.

The proximity broadcast receiver's own location may provide an approximate location for the wireless identity transmitter. The central server may process sighting messages, which may include signal strength information, to accurately locate the wireless identity transmitter.

Abstract: An authentication scheme is provided for securely establishing an association with a second device over a wireless communication link. A cryptographic key exchange is performed between a first device and a second device, wherein cryptographic information for the first and second device is obtained. The first and second devices may independently generate a confirmation value based on the cryptographic information. Each device may obtain a confirmation image based on their respective confirmation values. A confirmation image is uniquely associated with a confirmation value so that no two confirmation values can be associated with the same confirmation image. The images for both the first and second devices are provided to an operator for authentication. If the confirmation images are identical, an association between the first and second devices may be confirmed by the operator. Comparing confirmation images may increase the reliability of operator authentication and is more efficient than comparing values.

Abstract: Simultaneous operation of a short-ranged time division duplex (TDD) system with a mobile wireless broadband system may be implemented through scheduling and aligning both sets of communications. After determining a TDD frame configuration of the mobile wireless broadband system, a slot map is generated identifying slot-size selection information for each slot in the TDD frame configuration available for simultaneous operation. The slot-size selection information aligns the communication packet structure of the short-ranged TDD system and the uplink/downlink boundary of the TDD frame configuration. The communication device then transmits the slot map to a short-ranged TDD device for establishing the simultaneous operation.

Abstract: Interference from other wireless technology co-resident on a Bluetooth-capable device may render one or more Bluetooth frequencies unusable for a Bluetooth introduction sequence. In this case, one or more usable frequencies may be substituted for the one or more unusable frequencies to permit the introduction sequence to proceed. The one or more usable frequencies may be selected from a known set of usable frequencies in the current Bluetooth frequency train. Alternatively, a frequency re-mapping process may be used to select the one or more usable frequencies from the current Bluetooth frequency train.

Abstract: Embodiments determine that interference between two radio transmissions is causing, or has the potential to cause, a network device to fail to receive acknowledgement packets. In response to such a determination, the embodiments lower an acknowledgement packet transmission bit rate to increase the likelihood that an acknowledgement packet can be successfully received, thereby avoiding needless retransmission of packets that have been successfully received.
