Abstract

A method and apparatus for reducing an effect of user interference on other users in an uplink of a radio access network using interference suppression. A user, for example, the user experiencing the highest interference, is selected from a plurality of users using the radio access cell. A perceived Rise over Thermal value for the user after interference suppression is predicted in the event that scheduling grants to an interfering user in the radio access network are altered. On the basis of the prediction, scheduling grants to the interfering user are altered, thereby reducing the interference for the selected user.
