Abstract: Techniques for controlling a gain state of a wireless receiver involve causing the wireless receiver to enter into a sleep mode; causing the wireless receiver to exit from the sleep mode and enter into a wake-up period; providing, via a multiplexer, a stored gain control state value to the wireless receiver for use during a warm-up period of the wake-up period, the stored gain control state value being previously read from a gain controller during a previous wake-up period of the wireless receiver; and after the warm-up period of the wake up period, providing, via the multiplexer, a current gain control state value from the gain controller to the wireless receiver for use during the wake up period, the current gain control state value being based on a signal level of a currently-received signal in the wireless receiver.

Abstract: 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.

Abstract: A “Real-Time-Ready Analyzer” combines a data stream management system (DSMS) with a map-reduce (M-R) framework to construct a streaming map-reduce framework that is suitable for real-time Behavioral Targeting (BT) (or other temporal queries). The Real-Time-Ready Analyzer allows users to write “dual-intent” temporal analysis queries for BT. These queries are succinct and easy to express, scale well on large-scale offline data, and can also work over real-time data. Further, the Real-Time-Ready Analyzer uses the aforementioned streaming map-reduce framework to provide dual-intent algorithms for end-to-end BT phases. Experiments using real data from an advertisement system show that the Real-Time-Ready Analyzer is very efficient and incurs orders-of-magnitude lower development effort than conventional systems.

Abstract: A mobile device detects whether its temperature is within a first or second range of values, and operates in a full communication state within the first range and a limited communication state within the second range. The mobile device receives a communication request for establishment of a voice call or for communication of a user data message. In the full communication state, the mobile device permits an emergency or non-emergency voice call to be established, and permits a user data message to be communicated. In the limited communication state, the mobile device inhibits a non-emergency voice call from being established, but permits an emergency voice call to be established.

Abstract: One illustrative method of reducing signal interference in a wireless receiver includes receiving a radio frequency (RF) signal; amplifying the received RF signal with a gain G; producing a baseband signal from the amplified RF signal; producing a signal-to-interference (S/I) ratio from the baseband signal; and adjusting the gain G based on the S/I ratio. Preferably, the gain G is varied over a time period to produce a plurality of S/I ratios, so that the gain G corresponding a maximum S/I ratio produced over the time period can be selected for optimal performance. With this technique, higher accuracy is provided as intermodulation distortion is accounted for in the S/I ratio. Advantageously, the S/I ratio calculations and the gain adjustments are performed digitally by one or more processors such as a digital signal processor (DSP).

Abstract: In one illustrative example, methods and apparatus for use in buffering PTT voice communications are described. A mobile station sends a PTT voice communication request in a wireless communication network. Prior to receiving a floor grant in response to the PTT voice communication request, the mobile station receives voice input signals and buffers digital voice data corresponding to the voice input signals, where the digital voice data is produced by encoding and compressing the voice input signals. The mobile station receives the floor grant in response to the PTT voice communication request. Upon receipt of the floor grant, the mobile station retrieves the buffered digital voice data and continues to buffer digital voice data corresponding to the voice input signals, until all of the buffered digital voice data has been sent.

Abstract: Methods and apparatus for limiting communication capabilities in mobile communication devices are disclosed. In one illustrative example, an operating variable of a mobile communication device is detected to be within one of a first range of values, a second range of values, and a third range of values. The mobile device operates in a full communication state if the operating variable is detected to be within the first range of values, a first limited communication state if the operating variable is detected to be within the second range of values, or a second limited communication state if the operating variable is detected to be within the third range of values. When receiving a communication request for establishment of a voice call or for communication of a user data message, the mobile device permits or prohibits the communication depending on the communication state, and preferably depending on whether the communication request is for a non-emergency or emergency communication. In one preferred embodiment, the operating variable is a temperature of the mobile device.
