<p><P>PROBLEM TO BE SOLVED: To propose various schemes for reducing and correcting transmission errors where: base stations control the transmission rate that is used by UE (user equipment) to forward them information; a UE periodically forwards a rate request to a base station if the UE needs to have its data transmission rate to the base station increased or decreased, and the base station responds with a rate command; an error can occur in the transmission of the rate command, such that a rate R<SP>nb</SP>transmitted by the base station and detected by the UE as R<SP>ue</SP>may not match. <P>SOLUTION: A first scheme involves periodically resetting the transmission rate of the base station and UE with a reference rate. Second to fourth schemes involve periodically comparing the transmission rates of the base station and UE, and replacing the rate of the UE if they differ. A fifth scheme involves a filtering of the feedback command in order to reduce the impact of error propagation. A sixth scheme, which may be used separately or in conjunction with any of the foregoing schemes, involves adjusting a power offset with a repetition factor. All of the schemes are modified during a soft handover of the UE from the base station to a new base station. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
