Abstract: A method for multi-radio coexistence receives historical frequency usage information and historical time usage information from a first radio. The method creates a time and frequency mask by extrapolating the historical frequency and time usage information to future times and frequencies when the first radio will be active and uses the time and frequency mask to schedule a second radio to avoid receiving when the first radio will likely be active. A related apparatus has a collocated radio input for receiving timing usage information, a non-collocated radio input for receiving frequency usage information, and a time and frequency mask generator for creating a time and frequency mask using the timing usage information and the frequency usage information. The method and apparatus predicts collocated and non-collocated radio activity in both the time and frequency dimensions to reduce interference among radios operating in overlapping or adjacent frequency bands.

Abstract: Disclosed are a queue controller and method thereof for dual mode I/O devices and methods for transmission of a short range radio link such as a Bluetooth link that is a bi-directional real-time audio communication signal that can be over a first transport or a second transport. The described queue controller can transform a single input queue having heterogeneous packet types to a queue having homogeneous packet types in a case where heterogeneous audio packet types are anticipated. According to control signals that can be based upon operating conditions and transport selection, a first control signal or a second control signal can control the single input queue transformation. After a transport is selected, a single input queue can be processed by a queue controller configured to transform the single input queue having heterogeneous packet types to a queue having homogeneous packet types.

Abstract: A method for coexistence of an orthogonal frequency division multiple access (OFDMA) receiver (117) such as a WiMAX receiver with a synchronous frame-based transmitter (115) such as a Bluetooth transmitter within a mobile station (110) receives an estimated media access protocol (MAP') signal indicating when a MAP message is expected to be received by the OFDMA receiver (117) and uses it at a Bluetooth shutdown signal (190) at least when a MAP message is expected to be received. The MAP' signal can be taken directly from the ODFMA transceiver (117) or it may be produced through analysis of a receiver-enable (RXE) signal that includes not only MAP symbols but also downlink data symbols. The RXE signal can be analyzed using interrupt-and-timer, Fast Fourier Transform, covariance, and/or delay-locked loop techniques to extract historical MAP symbol information and generate expected MAP symbol information. Shutting down a Bluetooth transmitter during expected MAP message receipt permits the OFDMA receiver to maintain synchronicity with an access point while not requiring the Bluetooth transmitter to shut down every time the OFDMA receiver expects to receive an OFDMA symbol.

Abstract: In a method of controlling power level of transmit signals from a wireless communication device that is communicating with a plurality of wireless ad-hoc network nodes as part of an ad-hoc network, a value of a usage parameter of a communication between the wireless device and a first wireless ad-hoc network node of the plurality of nodes is detected. A power level of a transmit signal from the wireless device to the first wireless ad-hoc network node is set to a level corresponding to the value of the usage parameter. A device for adjusting a power level in a wireless device includes a parameter detection circuit, that detects a parameter indicative of a relationship between the wireless device and a wireless ad-hoc network node, and a power selection circuit that sets a transmit signal power level from the wireless device to a level corresponding to the parameter detected by the parameter detection circuit.

Abstract: Disclosed are dual mode I/O devices and methods for transmission of a short range radio link such as a Bluetooth link that is a bi-directional real-time audio communication signal that can be over a synchronous circuit-switched transport and an asynchronous packet-switched transport either sequentially or simultaneously. Also disclosed are dual mode wireless headset systems and methods of at least two dual mode I/O devices and more particularly including a wireless audio terminal and an audio gateway for transmission of a bi-directional real-time audio communication signal that can be over a synchronous circuit-switched (SCO) transport and an asynchronous packet-switched (ACL) transport either sequentially or simultaneously. Having both SCO and ACL modes available may allow the user to optimize voice quality or data throughput under different operating conditions. The user may benefit from better Bluetooth voice quality and may have the flexibility of using either mode depending upon the situation.
