摘要： A method and apparatus for compensating is described, in which a tuning network is electrically coupled to an antenna and to a phase shift network. Baseband signals travel to and from the phase shift network. A controller communicatively linked to the tuning network and to the phase shift network receives data regarding the state of a communication device. The controller changes the impedance of the tuning network, and changes the phase shift of the phase shift network based on the received data. The received data may include information regarding the channel, band, or sub-band on which a communication device is communicating; information regarding on the application state of the device; information regarding the modulator and demodulator state of the device; and information regarding the state of the communication device's antenna.

摘要： A method and system provides an automatic frequency correction (AFC) within a wireless communication device. A synchronization controller estimates first and second frequency errors respectively associated with a first received signal corresponding to a first receiver path and a second received signal corresponding to a second receiver path. The synchronization controller determines a value and a type of target clock of a first AFC associated with the first frequency error. If the first AFC is not generated to target a shared clock such as a reference clock, the synchronization controller generates a second AFC to compensate for the second frequency error. However, if it is determined that the first AFC targets a shared clock, the synchronization controller generates the second AFC to compensate for the first AFC and the second frequency error. The synchronization controller synchronously applies the first and second AFCs to the relevant clocks.

摘要： A method and system performs antenna tuning to minimize interference affecting signal reception within a wireless communication device. An antenna tuner controller determines whether the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation. In response to determining that the wireless communication device concurrently provides the simultaneous signal transmission and reception and the dual signal propagation, the antenna tuner controller determines a current mode of operation corresponding to simultaneous signal transmission and reception and the dual signal propagation. Based on the mode of operation determined, the antenna tuner controller identifies a priority for performing antenna isolation to minimize interference affecting signal reception when the wireless communication device actively communicates within the specific mode of operation. In response to the identifying the priority for performing antenna isolation, the antenna tuner controller performs antenna impedance tuning that provides antenna isolation corresponding to the priority.

摘要： A method, transceiver integrated circuit (IC), and communications device that employs a PIN Diode switch in connection with a transceiver integrated circuit in order to provide a highly linear path for simultaneously transmitted signals in a multi-band wireless communications device. A high linearity switch (HLS) utility/controller configures the PIN diode switch for switching between dual and single transmission modes. In the dual transmission mode, both a series PIN diode and a shunt PIN diode of the switch are biased to an on-state. A first transceiver generates and simultaneously transmits different transmission signals occupying different frequency bands to at least one antenna by utilizing a highly linear circuit path that includes the series PIN diode. In single transmission mode, both diodes are biased to an off-state which allows a second transceiver to transmit a single transmission signal to at least one antenna via a switch path with a low insertion loss impact.

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 the application 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.
