Claim Text:
1. A method for scheduling users in a mobile or wireless radio communication system comprising at least one base station with a multiple antenna system and at least two users, said base station communicating with users using precoding weights at said multiple antenna system, an indication on precoding weights to be used for communication with a first user being sent by said first user on a feedback channel to said base station, said method further comprising: expressing said precoding weights used at said multiple antenna system as a combination of two types of precoding weights, a first type of precoding weights relating to long term channel information and a second type of precoding weights relating to short term channel changes; sending on said feedback channel from said first user an indication related to precoding weights of said first type which, if used at said multiple antenna system for communication with a second user, would cause interference below a threshold on said first user if both said first and second users were scheduled on identical resources or sending on said feedback channel an indication related to precoding weights of said first type which, if not used for communication with a second user, would cause interference below a threshold on said first user if both users were scheduled on identical resources; and sending on said feedback channel an indication related to precoding weights of said second type which, if used in combination with said precoding weights of said first type at said multiple antenna system for communication with a second user, would cause interference below a threshold on said first user if both said first and second users were scheduled on identical resources or sending on said feedback channel an indication related to precoding weights of said second type which, if used in combination with said precoding weights of said first type at said multiple antenna system for communication with a second user, would cause interference below a threshold on said first user if both said first and second users were scheduled on identical resources.
