Patent number: 7869410Abstract: Forward link transmission power to a user terminal in a wireless communications system having a plurality of beams is controlled by determining a baseline power level, Pbaseline, from a received active pilot channel signal-to-noise ratio (SNR); determining a power margin, Pmargin, from an identified interference susceptibility; determining a power level correction, Pcorrection, based on an identified packet error rate (PER); and setting Ptransmit based on Pbaseline, Pmargin, and Pcorrection. For example, Ptransmit may be set to a power level that is substantially equal to the sum of Pbaseline, Pmargin, and Pcorrection. The determination of each of Pbaseline, Pmargin, and Pcorrection may be performed in independently running control loops or processes.Type: GrantFiled: July 23, 2007Date of Patent: January 11, 2011Assignee: QUALCOMM IncorporatedInventors: Jon J.

Patent number: 7558226Abstract: A Wireless Communication Device (WCD) inter-operates with a Code Division Multiple Access (CDMA) communication system. The WCD operates in an idle mode wherein the WCD transitions between a sleep state to conserve power and an awake state to receive one or more paging signals. The WCD attempts to reacquire a first pilot signal associated with a first paging signal that was previously being demodulated, and a second pilot signal that was previously being tracked. The WCD performs a handoff from the first paging signal to a second paging signal associated with the second pilot signal when the attempt to reacquire the first pilot signal fails and the attempt to reacquire the second pilot signal is successful.Type: GrantFiled: October 15, 2002Date of Patent: July 7, 2009Assignee: Qualcomm IncorporatedInventors: Jon J. Anderson, Francis Ngai, Glenn Salaman, Nicholson R. Gibson

Patent number: 7366142Abstract: A mobile wireless terminal (MWT) includes multiple wireless modems. The multiple modems have their respective transmit outputs combined together to produce an aggregate transmit output. The multiple modems can concurrently transmit data in a reverse link direction and receive data in a forward link direction. The MWT is constrained to operate under an aggregate transmit power limit. Each of the multiple modems has an individual transmit limit related to the aggregate transmit power limit. An MWT controller adjusts the individual transmit power limits in the multiple modems based on an aggregate transmit power limit of the MWT and respective transmit power estimates from the modems, to cause each individual transmit power limit to track a corresponding individual modem transmit power.Type: GrantFiled: September 1, 2005Date of Patent: April 29, 2008Assignee: QUALCOMM IncorporatedInventors: Francis M. Ngai, Aziz Gholmieh, Douglas A. Gerecht, Jon J. Anderson, William R. Panton

Patent number: 7260411Abstract: A system and method for determining timing offset errors in a low earth orbit satellite system based upon Doppler and Doppler rate of change is provided. A user terminal determines first and second timing offsets respectively associated with first and second satellite beams from respective first and second satellites. Next, the user terminal determines the Doppler and Doppler rate of change associated with the first and second satellite beams. A timing offset is estimated from the measured Doppler and Doppler rate of change and is then compared with the user terminal's own determined timing offset. If the comparison does not produce a value within a predetermined threshold, a beam identification error is declared.Type: GrantFiled: December 7, 2005Date of Patent: August 21, 2007Assignee: QUALCOMM IncorporatedInventors: Jon J.

Patent number: 7099623Abstract: A Wireless Communication Device (WCD) includes multiple fingers that track one or more tracked transponder beams. Each tracked beam is from a respective tracked transponder. The WCD determines a tracked-beam searcher energy for each of the tracked beams, and an untracked-beam searcher energy for each of one or more untracked beams from each of the tracked transponders. The WCD attempts to determine a preferred one of the untracked beams that should become a tracked beam. This determination is made based on the tracked-beam and the untracked-beam searcher energies. The WCD assigns, or alternatively, reassigns, a finger to the preferred untracked beam when the attempt to determine a preferred untracked beam is successful. The transponders may be satellites or base stations.Type: GrantFiled: December 20, 2002Date of Patent: August 29, 2006Assignee: QUALCOMM IncorporatedInventors: R. Nicholson Gibson, Jon J.

The multiple modems have their respective transmit outputs combined to produce an aggregate transmit output. The multiple modems can concurrently transmit data in a reverse link direction and receive data in a forward link direction. The MWT is constrained to operate under an aggregate transmit power limit. Each of the multiple modems has an individual transmit limit related to the aggregate transmit power limit. When operating, over-limit ones of the multiple modems are deactivated and then reactivated to keep an aggregate transmit power of all of the modems below the aggregate limit, and to maximize data through-put on the forward and reverse links.Type: GrantFiled: October 29, 2002Date of Patent: June 6, 2006Assignee: Qualcomm IncorporatedInventors: Francis M.

Publication number: 20040029545Abstract: A method and system for reliably returning to a traffic channel in a wireless communications system after performing E911 GPS measurements is provided. The method establishes a communications link using a device in a communications system having at least one communication channel. The device also includes a processor and a tuner and is configured to establish communication over the communication channel. The communication is based upon receiving a first radio frequency (RF) signal including data frames. The method includes tuning to receive a second RF signal, wherein the tuning interrupts reception of the first RF signal. The communication over the communication channel is maintained during the interruption. The method also includes processing the data frames during the tuning, updating a signal search space associated with the first RF signal during the processing, and searching for the first RF signal within the updated search space. The first RF signal is then re-acquired in accordance with the searching.Type: ApplicationFiled: August 9, 2002Publication date: February 12, 2004Inventors: Jon J. Anderson, Bijan Tuysserkani
