摘要： A method (700) and mobile computing device (200) are described. In its simplest form, the method includes the steps of: operating (710) an application in synchronous communication with an application server via a persistent IP session, defining an active mode, wherein the synchronous communication is automatically enabled by establishing a persistent IP session according to a prearranged schedule; and providing (720) a dormant mode wherein the synchronous communication is automatically disabled in the mobile device by closing the persistent IP session according to the prearranged schedule. Advantageously, energy can be saved in the mobile computing device, thereby extending the life of an energy storage device or a battery. By the use of intelligent pushing management, substantial energy savings can be gained, by using prearranged scheduling of dormant and active modes.

摘要： A method, transceiver integrated circuit (IC), and communications device for generating antenna tuning states derived from a pre-established trajectory of tuning states to adjust a detected signal level towards a preset, given value. A tuning state generation (TSG) controller determines whether a detected signal level matches a given value. If the detected signal level does not match the given value, the TSG controller selects an initial preset tuning state from a pre-established trajectory corresponding to a pre-identified operating condition that best matches a current operating condition. The TSG logic forwards the initial preset tuning state to the antenna tuner to trigger impedance transformation. Following generation of the initial preset tuning state, the controller receives an updated detected signal level. If the updated detected signal level fails to match the given value, the controller generates an incremental tuning state that is interpolated between the initial and a final preset tuning states.

摘要： A transmission power control method subdivides one or more transmission power steps as defined in a system specification into multiple sub-steps. A base station (290) instructs a mobile station (280) to use a defined power step, and the mobile station (280) initially selects a maximum power sub-step within the requested power step during an initial RACH (225) transmission. During the duration of the call, the mobile station (280) dynamically adjusts the power sub-step based on measured signal reception quality and channel conditions. The result is an improvement in call completion rates with only a minor reduction in battery life.

摘要： A power amplifier controller for detecting saturation of the power amplifier (203) and corrects the automatic output control voltage (231) to avoid any further saturation. A detector (211) detects the power of the radio frequency (RF) output signal (211) and generates a signal (229) correlated to the detected power. Comparator (217) compares changes in that signal (229) to changes in the voltage of the AOC signal (231). The comparator (217) generates a signal (233) correlated to saturation of the power amplifier (203) for a DSP (223). The DSP (223) checks the status of this signal (233). Upon detecting saturation, an algorithm contained within the DSP methodically reduces the voltage of the AOC signal (231) until there is a change in the power of the RF output signal (211).

摘要： A method and system mitigates receiver desensitization caused by a reverse inter-modulation distortion (IMD) signal generated by a power amplifier associated with one of at least two concurrently operating transmitters. A power amplifier controller (PAC) determines whether at least one power amplifier operating in a first operating state generates a reverse IMD signal that can substantially interfere with at least one receive channel due to a concurrent operation of at least two concurrently operating transmitters. In response to determining that at least one power amplifier generates the reverse IMD signal when in the first operating state, the PAC initiates a second operating state of the power amplifier to increase the linearity of the at least one power amplifier in order to reduce the reverse IMD signal. The PAC initiates the second operating state by adjusting parameters of the power amplifier.

摘要： A method (200) and device (300) for saving energy in a wireless communication device configured to maintain a persistent communication session over a wireless network with an application server. The method (200) can include: opening (210) a persistent communication session with an application server via a cellular network; measuring (220) a round trip time (RTT) from sending a message to theapplication server to receiving an acknowledgement message from the application server; and automatically transitioning (230) the device from a first operating state to a second operating state after an amount of time in the absence of subsequent data traffic exceeding a predetermined threshold, wherein power consumption associated with the second operating state is less than power consumption associated with the first operating state, and the predetermined threshold is a function of the measured round trip time. Advantageously, the method (200) can measure the actual RTT and transition to a low power based on the measured RTT exceeding a predetermined threshold, before the expiration of a network configured inactivity timer and in the absence of subsequent data traffic, which helps to minimize unnecessary power drain in a wireless communication device and minimizes inefficiencies in connection with data exchanges between a network and a wireless communication device.
