Abstract: A method includes steps, performed by a wireless device for accessing a wireless network through network base stations. The steps include selecting a reverse link cost metric from a list of reverse link cost metrics. A reverse link cost is determined according to the selected reverse link cost metric. A plurality of base stations are partitioned into a plurality of candidate base stations and a plurality of excluded base stations. The plurality of base stations are substituted with the candidate base stations, thereby reducing the cardinality of the plurality of base stations by the cardinality of the plurality of excluded base stations. A candidate base station is selected from a plurality of the base stations. A probe signal is sent at the reverse link cost to the candidate base station. A response from the candidate base station is waited for within a timeout period.

Abstract: A method of making polymeric particles having a controlled size and size distribution, and in particular a method for the preparation of chemically prepared toners, via evaporative limited coalescence process, wherein basic silicate salts are employed to remove particulate stabilizer from precipitated polymer particles. The process includes the steps of dispersing polymeric binder materials and optional additives in an organic solvent to form an organic phase. The organic phase is dispersed by high shear agitation in an aqueous phase containing a particulate stabilizer, e.g. colloidal silica, to form a dispersion of small droplets of the organic phase in the aqueous phase. The dispersion is homogenized and the organic solvent is removed from the dispersed particles in the dispersion by evaporation, and polymeric particles are precipitated with particulate stabilizer on the surface thereof, which are then recovered, treated with a basic silicate salt to remove particulate stabilizer, and washed and dried.

Abstract: A transmitter for a mobile device utilizes at least one mapper in order to improve power efficiency while still meeting out of band spurious emissions and waveform quality requirements. An encoder and modulator generates an encoded and modulated transmit signal from an input signal. A digital to analog converter coupled to the encoder and modulator generates an analog representation of the encoded and modulated transmit signal. An amplifier stage coupled to the digital to analog converter amplifies the analog representation of the encoded and modulated transmit signal to generate a transmission signal. The transmitter further comprises an amplifier control block configured to generate an amplifier control signal for adjusting at least one parameter of the amplifier stage. At least one mapper is provided in the amplifier control block, used to determine the amplifier control signal based on a peak to average power ratio and an average transmit power of the transmission signal. Environmental and operating conditions of the transmitter may be accounted for as well in the mappers.

Abstract: Methods and apparatus for facilitating the determination of Global Positioning System (GPS) location information for a mobile station without disrupting communications of a voice call (e.g. a 911 emergency call). In one illustrative example, the mobile station causes GPS navigational-type data to be regularly or periodically received and stored in memory prior to the voice call. At some point in time, the mobile station receives a voice call request to initiate the voice call. In response, the mobile station derives GPS assistance data based on the GPS navigational-type data. The mobile station then causes a GPS fix to be performed using the GPS assistance data, to thereby obtain GPS measurement data. Thereafter, the mobile station causes the voice call to be established and maintained through the wireless network.

Abstract: The application relates to wireless networks and more particularly to a method of reducing factory test time of receiver sensitivity in a Code Division Multiple Access (CDMA) wireless device. Under TIA/EIA/-98E, the radio frequency (RF) sensitivity of a CDMA wireless receiver is the minimum received power, measured at the mobile station antenna connector, at which the frame error rate (FER) does not exceed 0.5% with 95% confidence. In order to reduce the test time of FER test method, the relation between correlated energy (or Ec/Io) and FER is determined using simulated traffic and the correlated energy (or Ec/Io) measurement is then used as the test parameter on like models to achieve the same or superior test confidence with significantly reduced test time.

Abstract: 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.

Abstract: The settling time of a wireless receiver is reduced by providing a previously utilized gain control state value to an amplifier of a receiver front end during a warm-up portion of a wake-up period of the wireless receiver which follows a sleep period. One illustrative method includes the steps of receiving a notification signal which indicates that the wireless receiver is to be placed in a sleep mode, reading a gain control state value from a gain controller based on receiving the notification signal, storing the gain control state value in memory, providing the stored gain control state value from the memory to the wireless receiver during a warm-up period of a second wake-up period following the first wake-up period, and providing a gain control state value from the gain controller to the wireless receiver based on a signal level of a currently received signal of the wireless receiver after the warm-up period.
