摘要： Systems, methods, and devices are described for power saving techniques in mobile devices. A signal quality metric of a received wireless signal may be monitored. A determination is made when the signal quality metric exceeds a threshold quality level for a time period. A subset of the signal processing functionality may be de-activated responsive to the determination. There may be different thresholds depending on whether the mobile device is in idle or connected mode. There may also be different thresholds for various signal processing algorithms.

摘要： A method for reducing idle mode power consumption is disclosed. An idle mode is entered. A neighboring base station is selected. If the selected neighboring base station is assigned a high-frequency monitoring mode, a signal strength of the neighboring base station is measured. A low-frequency monitoring mode is assigned to the selected neighboring base station if the signal strength of the selected neighboring base station has been below a power threshold for longer than a time threshold. Other aspects, embodiments, and features are also claimed and described.

摘要： In applications employing phase-shift keying modulation, a phase rotator as disclosed herein is used to rotate the constellation of signal vectors before carrier modulation in order to maximize modulator output power. Such a rotator may be applied in the digital domain (to complex signals having either binary-valued or multi-valued components) or in the analog domain.

摘要： The described aspects include a user equipment (UE) apparatus and corresponding method of communicating with multiple networks using multiple subscriptions. The UE can establish a call in a first network related to a first subscription over a transceiver. During the call, the UE autonomously tunes the transceiver to a frequency of a second network related to a second subscription within a defined gap during the call. The UE can monitor one or more channels in the second network during the defined gap for one or more idle-mode signals.

摘要： A need to store data between a producing stage and a consuming stage commonly arises in digital processing applications. However, factors such as fabrication process limitations and circuit area constraints may restrict the amount of available storage. A novel method and apparatus for data buffering are disclosed which use less data storage than would be required by double buffering techniques.

摘要： Interleavers are used in data transmission and storage applications to introduce diversity into a data stream, thereby making adjacent symbols more independent with respect to a transfer environment of variable quality. Conventional interleavers require storage in whole units of data blocks. This storage requirement complicates implementations for applications where available circuit area is limited and data rates and block sizes are large. A novel interleaver produces an interleaved data block using storage space that is only a fraction of the size of the input data block.
