Patent number: 6580913Abstract: The present invention concerns the efficient use of the radio spectrum in wireless communications. Channel occupancy data and channel availability data concerning a specific base station and its neighbors are used to assign frequency channels to mobile units and/or base stations. The channel occupancy and availability data may be located at a base station or at a mobile switching center. Channels are preferably assigned as channel pairs.Type: GrantFiled: October 16, 2000Date of Patent: June 17, 2003Assignee: Lucent Technologies Inc.Inventors: Pi-Hui Chao, Chih-Lin I

Patent number: 6201799Abstract: A Multicode (MC) Code Division Multiple Access (CDMA) receiver receives J encoded multicode channels (where J>1) over L multiple air signal paths (where L>1) and forms a decorrelator output vector in which for each of the J multicode channels, the interference caused by the other J−1 multicode channels has been cancelled. When the MC CDMA receiver is a coherent receiver, a pilot interference canceller cancels a received pilot signal from the J channel code of each of the received J multicode channels prior to forming the decorrelator output vector.Type: GrantFiled: May 1, 1997Date of Patent: March 13, 2001Assignee: Lucent Technologies, IncInventors: Howard C.

Patent number: 6088335Abstract: A code division multiple access system provides a way of allocating an increased data rate to a requesting mobile station. A mobile station requesting a data rate in excess of the basic data rate sends received pilot strength data for its base station and base stations in adjacent cells. The received pilot strength data is used to determine an increased data rate to be assigned to the requesting mobile station. One feature assigns an increased data rate based on the difference in the maximum received received pilot strength data from a non-active base station (one not in connection with the mobile station) and the maximum received pilot strength data from an active base station (one in connection with the mobile station). Yet another feature utilizes a series of threshold levels, each pair of levels associated with a different permitted data rate. Using the received pilot strength data, a data rate is determined which satisfies all adjacent cell interference concerns.Type: GrantFiled: April 21, 1997Date of Patent: July 11, 2000Assignee: Lucent Technologies Inc.Inventors: Chih-Lin I, Sarath Kumar, Sanjiv Nanda

Patent number: 6069883Abstract: A code division multiple access system method and apparatus provides for allocation of increased bandwidth to a requesting mobile station. An access controller receives a data burst request (from either a requesting mobile station or from an external network already in connection with the mobile station) requesting a first data rate in excess of the basic data rate B allocated to a mobile station of a first cell. The access controller determines an increased data rate which is to be granted to said mobile station without causing excessive interference at said first cell and at least one adjacent cell and transmits a data burst assignment to a base station of said first cell indicating the increased data rate which has been granted to said mobile station.Type: GrantFiled: April 8, 1997Date of Patent: May 30, 2000Assignee: Lucent Technologies IncInventors: Richard Paul Ejzak, Subhasis Laha, Sarath Kumar, Douglas Knisely, Sanjiv Nanda, Chih-Lin I

Patent number: 6067292Abstract: A Code-Division Multiple Access (CDMA) receiver removes the pilot signal from the received signal. The pilot signal is defined by its multipath parameters (amplitudes, phase shift and delays) and its signature sequence. Since this information is known at the user's receiver terminal (i.e., handset), the pilot signals of the interfering multipath components of the baseband received signal are detected and removed prior to demodulation of the desired multipath component. The pilot signal may be cancelled prior to or following the data accumulation stage. The pilot signal cancellation can be switched on and off depending on the detected path signal level.Type: GrantFiled: April 30, 1997Date of Patent: May 23, 2000Assignee: Lucent Technologies IncInventors: Howard C. Huang, Chih-Lin I, Stephan ten Brink, Giovanni Vannucci
