  • Patent number: 9629058
    Abstract: Methods, systems, and apparatuses for wireless communication are described. A wireless station (STA) may receive a frame from an access point (AP) reserving a channel for a time period. The frame may include an information field associated with a tune away procedure performed by the AP during the time period. The STA may perform, based on the information field, direct communications with a neighboring device on the channel during the time period.

  • Patent number: 6505042
    Abstract: A system including a user station that prioritizes multiple cell sites (BTSs) based on the strength of a paging message being transmitted by the BTSs. The user station transmits a response message to one of the BTSs transmitting the paging message based upon selecting the access channel associated with the BTS from which the user station received the paging message having the strongest signal strength until a timeout period has expired, and subsequently transmits the response message on the access channel associated with the BTS from which the user station received the paging message having the next strongest signal strength. The user station includes a receiver to receive the paging message transmitted by multiple BTSs. The user station further includes a processor to analyze and prioritize the multiple BTSs into a sequence according to the signal strength of the paging message received. Coupled to the processor is a timer for timing the timeout period.

  • Patent number: 6374116
    Abstract: A method of adjusting transmit power in a CDMA portable phone to maintain adjacent channel power rejection (ACPR) passing margin includes the steps of amplifying a first radio frequency (RF) signal according to a first gain to produce a second RF signal, and amplifying the second RF signal according to a second gain to produce a third RF signal. A desired power level of the third RF signal is determined and a new gain value is computed from the desired power level. The first gain value is adjusted to the new value. A system for adjusting transmit power in a CDMA portable phone to maintain adjacent channel power rejection (ACPR) passing margin includes an automatic gain control (AGC) amplifier having an AGC input terminal, an AGC output terminal, and a control signal input terminal. The system also includes a power amplifier (PA) having a PA input terminal and a PA output terminal, wherein the PA input terminal is connected to the AGC output terminal.

  • Patent number: 6349222
    Abstract: A mobile telephone system and a method for answering a mobile telephone incoming call by a user's verbal command, to allow hands-free voice. The mobile telephone system includes a carkit and a mobile telephone. The mobile telephone has a programming key for pre-programming the user's voice greeting, a keypad for answering the call in telephone mode, a microphone for entering a user's verbal command for answering the call in carkit mode, a digital processor connected to the microphone for performing spectrum analysis and feature extractions of the user's verbal command in carkit mode, and a memory connected to the digital processor, having a database for storing the user's pre-programmed voice greeting digitized speech pattern. The pre-programmed voice greeting may be a factory-programmed voice greeting or the user's pre-programmed voice greeting, if previously initialized after pressing the programming key.
