    摘要: A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.

    摘要: Systems and methods can be implemented on a user device and eNBs to manage downlink interference at the user device. The user device in a cell associated with a corresponding serving base station may receive interference from one or more interfering base stations. The user device can identify a preferred radio resource set in response to the detected interference and transmit a preferred radio resource indication to at least the serving base station in response to the detected interference. The preferred radio resource indication can be used for identifying the preferred radio resource set associated with the serving base station.

    摘要: A communication device reads and stores in memory a state value which was utilized for operating a communication subsystem during a wake-up period of the communication subsystem. The device then causes the communication subsystem to enter into a sleep mode. Subsequently, the device causes the communication subsystem to exit from the sleep mode and enter into a current wake-up period. The stored state value is provided to the communication subsystem for use in operating the communication subsystem during a warm-up period of the current wake-up period. After the warm-up period of the current wake up period, a current state value is provided from a state controller to the communication subsystem for use in operating the communication subsystem during the wake up period. The current state value is determined based on a detected signal level of a current signal received in the communication subsystem.

    摘要: It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.

    摘要: In one illustrative example of the present application, a mobile communication device has one or more processors, a wireless transceiver adapted to provide communications through a wireless communication network, and a buffer memory for use in buffering a Push-To-Talk (PTT) communication from the mobile communication device. The one or more processors are operative to produce a mobile device indication message which indicates the mobile device's support for buffering of the PTT communication. This message is transmitted by the wireless transceiver to a PTT service entity through the wireless network. The one or more processors may be further operative to receive, from the PTT service entity through the wireless network, a network indication message which instructs the mobile device whether to use buffering for the PTT communication. The mobile device may use the buffer memory for the buffering of the PTT communication based on the network indication message from the PTT service entity.
