摘要： Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.

摘要： Methods and apparatus for power reduction in a wireless device having multiple receive paths are described herein. A wireless device configured for any one of multiple operating modes may utilize multiple receive signal paths to improve the receive signal quality in each of the operating modes. The wireless device may be configured to dynamically reconfigure a modulation coding scheme to compensate for varying signal qualities in some modes. The wireless receiver may be configured in other operating modes where the modulation coding scheme is fixed for a duration of the operating mode. The wireless device can conserve power when it is operating in a mode supporting a constant modulation coding scheme. The wireless device can determine a signal metric value of the received signals and can selectively power down or deactivate a receive signal path based on the value of the signal metric.

摘要： A method, apparatus, and non-transitory computer readable medium are provided for high current battery charging using IR dropout compensation. The method first measures a battery current value and then multiplies that battery current value by an effective resistance of the battery to produce an effective dropout voltage value. The effective battery voltage value is then compared with a desired battery top off voltage value. The switch mode battery charger output setpoint is adjusted based on the setpoint voltage. Battery current and terminal current are then compared. Charging is terminated if the battery current is less than the terminal current. If the battery current is greater than the terminal current the battery current value is measured again and the charging process continues until the condition is met.

摘要： In a wireless communication system, a mobility factor is used to influence handoff. If a subscriber station has been in a low mobility state for some period of time, the system may handoff operation from a first service type to a second service type. If the mobility factor indicates that the subscriber station is moving, the system may handoff operation from the second service type back to the first service type.

摘要： A method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller determines if sufficient network resources are available to conduct a inter-system soft handoff. If so, the base station controller generates a set of signaling messages that cause call processing resource to be allocated and for the call to be processed at the second cellular system. The base station controller then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit by way of the second cellular system as well as via one or more base stations to which the base station controller is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

摘要： First and second data sources transmit a data signal on a data connection and a transmit clock signal on a clock connection. The data signal is clocked into a FIFO resident in the network interface equipment in response to the transmit clock signal, and out of the FIFO to the network in response to a reference clock signal. The FIFO generates a signal indicating how full it is and a local clock generator which generates the transmit clock signal in response to this status indication signal. The first and second data sources hold the data signal and transmit clock signal high for longer than a single period of the reference clock signal when switching between them. The local clock generator alters an average rate of the transmit clock signal in response to the status indication signal from the FIFO in order to keep it half-full.

摘要： Techniques for efficiently generating a power supply are described. In one design, an apparatus includes an envelope amplifier and a boost converter. The boost converter generates a boosted supply voltage having a higher voltage than a first supply voltage (e.g., a battery voltage). The envelope amplifier generates a second supply voltage based on an envelope signal and the boosted supply voltage (and also possibly the first supply voltage). A power amplifier operates based on the second supply voltage. In another design, an apparatus includes a switcher, an envelope amplifier, and a power amplifier. The switcher receives a first supply voltage and provides a first supply current. The envelope amplifier provides a second supply current based on an envelope signal. The power amplifier receives a total supply current including the first and second supply currents. In one design, the switcher detects the second supply current and adds an offset to generate a larger first supply current than without the offset.
