Patent number: 7463631Abstract: A method for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) is calculated based on the channel condition and throughput for each user. In one embodiment, the system supports retransmission of data packets and sub-packets, wherein the retransmission information is used to schedule data transmissions. In another embodiment, at each time interval the system updates the priority factor for the user having the highest priority factor in the previous time interval. The priority factors of the other users remain unchanged.Type: GrantFiled: July 15, 2004Date of Patent: December 9, 2008Assignee: QUALCOMM IncorporatedInventors: Gang Bao, David Puig Oses

Patent number: 7315527Abstract: Embodiments disclosed herein address the need in the art for an extended acknowledgment/rate control channel. In one aspect, an acknowledgment command and a rate control command are combined to form a combined command. In another aspect, the combined command is generated in accordance with a constellation of points, each point corresponding to a pair consisting of a rate control command and an acknowledgment command. In yet another aspect, the points of the constellation are designed to provide the desired probability of error for the respective command pairs. In yet another aspect, a common rate control command is transmitted along with a combined or dedicated rate control command. Various other aspects are also presented. These aspects have the benefit of reduced overhead while providing acknowledgment and rate control to single remote stations and/or groups of remote stations.Type: GrantFiled: February 17, 2004Date of Patent: January 1, 2008Assignee: Qualcomm IncorporatedInventors: Yongbin Wei, Edward G.

Publication number: 20070287487Abstract: Methods and apparatus are presented for improving the feedback of channel information to a serving base station, which allows a reduction in the reverse link load while allowing the base station to improve the forward link data throughput. Over a channel quality indicator channel, a carrier-to-interference (C/I) symbol is transmitted over multiple slots at a reduced rate, which increases the likelihood that the base station can decode said symbol. The reduced rate mode can be selectively triggered by a high velocity condition or other unfavorable channel condition. The C/I symbol is used to determine transmission formats, power levels, and data rates of forward link transmissions.Type: ApplicationFiled: June 12, 2007Publication date: December 13, 2007Applicant: QUALCOMM IncorporatedInventors: David Puig-Oses, Yongbin Wei, Stein Lundby

Over a channel quality indicator channel, three subchannels are generated; the re-synch subchannel, the differential feedback subchannel, and the transition indicator subchannel. The information carried on each subchannel can be used separately or together by a base station to selectively update internal registers storing channel conditions. The channel conditions are used to determine transmission formats, power levels, and data rates of forward link transmissions.Type: ApplicationFiled: May 19, 2006Publication date: September 21, 2006Inventors: Peter Gaal, Joseph Odenwalder, Stein Lundby, David Puig-Oses
