Patent number: 9001735Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.Type: GrantFiled: December 10, 2012Date of Patent: April 7, 2015Assignee: QUALCOMM IncorporatedInventors: Roberto Padovani, Paul E.

Patent number: 8477742Abstract: Schemes to time-align transmissions from multiple base stations to a terminal. To achieve time-alignment, differences between the arrival times of transmissions from the base stations, as observed at the terminal, are determined and provided to the system and used to adjust the timing at the base stations such that terminal-specific radio frames arrive at the terminal within a particular time window. In one scheme, a time difference between two base stations is partitioned into a frame-level time difference and a chip-level time difference. Whenever requested to perform and report time difference measurements, the terminal measures the chip-level timing for each candidate base station relative to a reference base station. Additionally, the terminal also measures the frame-level timing and includes this information in the time difference measurement only if required. Otherwise, the terminal sets the frame-level part to a predetermined value (e.g., zero).Type: GrantFiled: May 3, 2010Date of Patent: July 2, 2013Assignee: QUALCOMM IncorporatedInventors: Francesco Grilli, Charles E.

Patent number: 8338991Abstract: Exemplary embodiments are directed to wireless power. A wireless power receiver includes a receive antenna for coupling with near field radiation in a coupling-mode region generated by a transmit antenna operating at a resonant frequency. The receive antenna generates an RF signal when coupled to the near field radiation and a rectifier converts the RF signal to a DC input signal. A direct current-to-direct current (DC-to-DC) converter coupled to the DC input signal generates a DC output signal. A pulse modulator generates a pulse-width modulation signal to the DC-to-DC converter to adjust a DC impedance of the wireless power receiver by modifying a duty cycle of the pulse-width modulation signal responsive to at least one of a voltage of the DC input signal, a current of the DC input signal, a voltage of the DC output signal, and a current of the DC output signal.Type: GrantFiled: February 25, 2010Date of Patent: December 25, 2012Assignee: QUALCOMM IncorporatedInventors: William H Von Novak, Charles E Wheatley, III, Stanley S Toncich, Ernest T Ozaki

Patent number: 8254279Abstract: Techniques for estimating thermal noise and rise-over-thermal (RoT) in a communication system are described. In an aspect, thermal noise in a sideband may be measured and used to estimate thermal noise in a signal band. In one design, received power in the sideband may be measured, e.g., by computing total power of FFT transform coefficients within the sideband. Thermal noise may be estimated based on (e.g., by filtering) the measured received power in the sideband. Received power in the signal band may also be measured. Total received power may be estimated based on (e.g., by filtering) the measured received power in the signal band. RoT may then be estimated based on the estimated thermal noise and the estimated total received power. The estimated RoT may be used to estimate an available load for a cell, which may be used to admit and/or schedule users in the cell.Type: GrantFiled: April 21, 2008Date of Patent: August 28, 2012Assignee: QUALCOMM IncorporatedInventors: Charles E.

Patent number: 8189540Abstract: Methods and apparatus used in a wireless communication system. A data request message may be periodically transmitting by a mobile station to a base station. The data request message may provide information about orthogonal codes to be used by the base station to communicate with the mobile station. The mobile station may receive data transmitted by the base station, the data being transmitted by the base station based on the information about the orthogonal codes provided in the data request message. The information about the orthogonal codes may be based on a quality measure made by the mobile station on a forward link pilot channel from the base station to the mobile station.Type: GrantFiled: August 21, 2009Date of Patent: May 29, 2012Assignee: QUALCOMM IncorporatedInventors: Roberto Padovani, Paul E Bender, Peter J.

Patent number: 8184611Abstract: In the present invention, the slave base station attains synchronization with the reference base station through messages transmitted from and received by a mobile station either in the soft handoff region between the reference base station and the slave base station or within a range which allows the mobile station to communicate with the slave base station. When the mobile station is not in communication with both the reference base station and the slave base station, then the round trip delay between the mobile station and the reference base station is measured by the reference base station. The reference base station communicates the PN code used by the mobile station over the reverse link to the slave base station. The slave base station acquires the signal from the mobile station and determines when the signal from the mobile station arrives. The slave base station then makes an estimate as to the length of the delay between transmission of a signal from the mobile station to the slave base station.Type: GrantFiled: November 13, 2007Date of Patent: May 22, 2012Assignee: QUALCOMM IncorporatedInventors: Edward G.
