Reverse Link (RL) data rate allocation in a High Data Rate (such as 1xEV-DO) system as a function of Forward Link (FL) channel quality. Rate shaping of a throughput profile for multiple Access Terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. In one embodiment the maximum data rates are adjusted as a function of the FL Signal to Interference and Noise Ratio (SINR) such as measured per serving sector or as a captured sum total of FL SINR. In still another embodiment the maximum data …

Why it's free to use
- Filed November 7, 2003 and granted April 21, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 7, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 7, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
