Abstract: Hybrid location determination for wireless communication device. Various services that may be used by a wireless communication device within a particular location may be referred to as location based services (LBS). As such, means by which the location of a wireless communication device that may use such available services, within such a locale, is made by using more than one type of location determination approach. For example, a wireless communication device includes communication capability (e.g., RX and TX) in accordance with a first communication protocol (e.g., Bluetooth) and also includes a communication capability (e.g., RX only) in accordance with a second communication protocol (e.g., WiFi/WLAN (Wireless Local Area Network)). The RX capability is operative to assist in location determination for the wireless communication device based on knowledge of at least one wireless communication device that communicates with the wireless communication device.

Abstract: 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.

Abstract: Angle of arrival and/or range estimation within a wireless communication device. Appropriate processing of communications received by a wireless communication device is performed to determine the angle of arrival of the communication (e.g., with respect to some coordinate basis of the wireless communication device). Also, appropriate processing of the communications may be performed in accordance with range estimation as performed by the wireless communication device to determine the distance between the transmitting and receiving wireless communication devices. There are two separate modes of packet processing operations that may be performed: (1) when contents of the received packet are known, and (2) when contents of the received packet are unknown. The wireless communication device includes a number of antenna, and a switching mechanism switches from among the various antennae capitalizing on the spatial diversity of the antennae to generate a multi-antenna signal.

Abstract: 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).

Abstract: Aspects of a method and system for transmit power control techniques to reduce mutual interference between coexistent wireless networks are provided. A coexistence terminal comprising a WLAN radio and a Bluetooth radio operating as a master device may transmit signals to one or more remote controllers comprising a slave Bluetooth radio to increase transmission power when the isolation between the coexistence terminal's WLAN and Bluetooth radios is below a threshold. Link manager protocol (LMP) signals may be utilized for changing the transmission power. When the isolation increases above the threshold, signals may be generated to reduce the remote controllers' transmission power. In some instances, in addition to increasing the transmission power of remote controllers, the transmission power of the Bluetooth radio or the WLAN radio may be reduced. The reduced Bluetooth or WLAN radio transmission power may be increased when the radio isolation in the coexistence terminal increases.

Abstract: A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

Abstract: 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.

Abstract: 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.

Abstract: Collaborative coexistence of co-located mobile WiMAX, wireless LAN, and/or Bluetooth radios. Within a communication device that includes multi-protocol communication capability, the various radio modules included within such a communication device operate cooperatively such that collisions are avoided between those various radios. When a first of the radio modules operates as governed by a relatively rigid frame structure, a second of the radio modules capitalizes upon that predetermined nature (of the relatively rigid frame structure) to support communication during times in which that first radio module has a lower level of activity (e.g., turned off completely, within a power savings mode, in a sleep mode, etc.). The radio module operation is performed within a time-orthogonal manner, such that multiple radio modules are not attempting to transmit or receive simultaneously.
