Title: Rate control protocol for long thin transmission channels
Inventor: TEIL ALAIN
IPC: H04B7/26
Filed: 2003-08-07
Abstract: The invention deals with rate control protocols having a probing phase during which the sending rate of the transmitter is repeatedly increased until a loss is reported by the receiver. Such probing phases are used by the transmitter to quickly increase its sending rate to a fair share of the transmission channel bandwidth. According to the invention, a fake loss is generated by the receiver when the sending rate has risen to the current capacity of the transmission channel so as to force the transmitter to terminate the probing. Application: wireless Internet access to audio-video streaming services.

Title: Method and apparatus for high rate packet data transmission
Inventor: PADOVANI ROBERTO
IPC: H04W40/16
Filed: 1998-11-03
Abstract: 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.
