Abstract: A method is performed by a wireless device. The method includes (a) preselecting a set of the base stations; (b) selecting a reverse link cost according to a preselected reverse link cost metric; (c) selecting a base station from the set of base stations; and (d) sending a probe signal at the selected reverse link cost to the selected base station. If a response is not received from the selected base station within a preselected time period and not all the base stations have been sent a probe signal at substantially the selected reverse link cost, then steps (c) through (d) are repeated with a different one of the base stations at substantially the selected reverse link cost. If a response is received from the selected base station within the timeout period, then the responding base station is selected to provide access to the wireless network.

Abstract: A method and apparatus for estimating oscillator signal variation due to temperature and for providing an estimated frequency to a GPS receiver in order to assist the GPS receiver to acquire the signals quickly is disclosed. A temperature sensor is closely thermally coupled with the crystal oscillator in the GPS receiver and during GPS tracking mode, when the error in the oscillator signal is known with precision, outer bounds of TCXO frequency at given temperatures are maintained, which may correspond to rising and falling temperature conditions. During acquisition mode, an estimated frequency value is provided to the GPS receiver based on a determined average of these bounds. Optionally, an uncertainty factor associated with the frequency estimated may also be provided. The two bounds take into account the hysteresis effects of the oscillator signal drift due to temperature so that a more accurate initial frequency estimate can be provided to the GPS receiver, thus reducing its average time to first fix.

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 “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: 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.
