Abstract
A reverse link rate control method and apparatus provide first rate control commands as the primary rate control for general ongoing control of the reverse link rates of one or more mobile stations. These first rate control commands comprise for example periodically transmitted common rate control commands that are generated as a function of reverse link loading and are used to control the reverse link rates of mobile stations whose service requirements currently do not require targeted reverse link rate control. The exemplary method and apparatus further provide second rate control commands on an as needed basis that are sent to targeted ones of the mobile stations to meet the specific Quality-of-Service requirements at individual mobile stations or groups of mobile stations. Supplemental rate control channels can be assigned and released dynamically to targeted mobile stations to provide supplemental rate control on an as-needed basis.
