Abstract: A multi-carrier cellular radio communication system includes a serving base station associate with a serving cell currently serving a mobile radio and a non-serving base station within range of the mobile radio and associated with a non-serving cell. The mobile radio can transmit to the serving base station at the same time over multiple radio frequency carriers. An estimate is made of inter-cell interference in the non-serving cell caused by uplink transmission by the mobile radio over one or more of the multiple radio frequency carriers over which the mobile radio is currently simultaneously transmitting. If the estimated inter-cell interference in the non-serving cell exceeds a predetermined threshold, then the inter-cell interference in the non-serving cell is reduced or limited by managing radio resources so that the estimated inter-cell interference in the non-serving cell is or becomes less than the predetermined threshold.

Abstract: The present disclosure relates to an uplink congestion control scheme. In one embodiment, an uplink congestion control method is provided, comprising steps of: determining whether or not a congestion status of a serving cell is changed based on a rise over thermal, RoT, measurement; sending to a set of user equipment, UEs, a signaling to indicate the change of the congestion status; and performing an uplink congestion control based on the RoT measurement and with enhanced transmission format combination, E-TFC, reselection by at least one UE from the set of UEs based at least on the signaling.

Abstract: A radio base station and a method therein for scheduling an uplink radio resource to a first user equipment in a wireless communication system which employs CDMA are provided. The method includes measuring an Interference Suppression (IS) gain for each user equipment in a set of user equipments currently being served by the radio base station. The method further includes determining a user constellation pertaining to information regarding the different user equipments in the set of user equipments and their respective bitrates, and updating a table of IS gains with the measured IS gain in bins corresponding to the determined user constellation. The method further includes predicting a load based on at least the updated table, and scheduling the uplink radio resource to the first user equipment at least partly based on the predicted load.
