Patent number: 8514764Abstract: This disclosure is directed to a repeater and base station control device implemented in a wireless communication system. The repeater includes a control unit capable of detecting signals sent from various base stations in the wireless communication system. In accordance with this disclosure, the repeater identifies a set of base stations that it can detect, and then sends information indicative of the set of base stations that the repeater can detect to a specific base station that gets repeated by the repeater. In this manner, the repeater can be used to help assess network topology. The base station control device receives the information from the base station and can use the information to update a neighbor list.Type: GrantFiled: April 30, 2004Date of Patent: August 20, 2013Assignee: QUALCOMM IncorporatedInventors: Kenneth Baker, Charles Wheatley, Daniel Willis, Leonid Sheynblat

Publication number: 20080117835Abstract: 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: ApplicationFiled: January 24, 2008Publication date: May 22, 2008Applicant: QUALCOMM INCORPORATEDInventors: Francesco Grilli, Charles Wheatley, Serge Willenegger, Parvathanathan Subrahmanya

Publication number: 20070066320Abstract: 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: ApplicationFiled: September 29, 2006Publication date: March 22, 2007Inventors: Roberto Padovani, Paul Bender, Peter Black, Matthew Grob, Jurg Hinderling, Nagabhushana Sindhushayana, Charles Wheatley

Publication number: 20060094460Abstract: A method and apparatus for controlling transmission power levels in a mobile communication system. The method provides for a closed-loop power control method. A mobile station provides information on the quality of the signal received from the base station, and the base station responds by adjusting the power allocated to that user in a shared base station signal. The transmission power is adjusted initially by a large increment and then ramped down at an increasingly decreasing rate. The mobile station also provides information to the base station as to its relative velocity and the base station adjusts its transmission power in accordance with this velocity information.Type: ApplicationFiled: December 6, 2005Publication date: May 4, 2006Inventors: Edward Tiedemann, Joseph Odenwalder, Charles Wheatley, Roberto Padovani

Publication number: 20060088134Abstract: A system and method for communicating information signals using spread spectrum communication techniques. PN sequences are constructed that provide orthogonality between the users so that mutual interference will be reduced, allowing higher capacity and better link performance. With orthogonal PN codes, the cross-correlation is zero over a predetermined time interval, resulting in no interference between the orthogonal codes, provided only that the code time frames are time aligned with each other. In an exemplary embodiment, signals are communicated between a cell-site and mobile units using direct sequence spread spectrum communication signals. In the exemplary embodiment, transmit power of mobile unit signals is controlled based on signal power received by the mobile unit and power adjustment commands sent to the mobile unit.Type: ApplicationFiled: December 7, 2005Publication date: April 27, 2006Inventors: Klein Gilhousen, Irwin Jacobs, Roberto Padovani, Lindsay Weaver, Charles Wheatley, Andrew Viterbi
