Interference cancellation

A radio base station configured to schedule an uplink radio resource to a first user equipment in a wireless communication system which employs Code Division Multiple Access (CDMA) the radio base station comprising:

• a receiving circuit configured to receive a plurality of signals from a set of user equipments currently being served by the radio base station in the wireless communication system,
• at least one processor;
• and
• memory coupled to the at least one processor and comprising computer readable program code embodied in the memory that when executed by the at least one processor configures the processor to:
• measure an Interference Cancellation (IC) gain for each user equipment in the set of user equipments currently being served by the radio base station, wherein the IC comprises canceling an interference within the plurality of signals received at the receiving circuit of the base station by processing respective ones of the plurality of received signals based on a measurement by the radio base station of at least one of the plurality of signals received at the receiving circuit of the radio base station,
• determine a user constellation pertaining to information regarding different user equipments in said set of user equipments and their respective bitrates,
• select a bin of a plurality of bins in an IC gain table responsive to the determined user constellation, wherein the plurality of bins correspond to different user constellations,
• update the IC gain table with the measured IC gain in the selected bin,
• predict a load based on said updated IC gain table, and
• schedule the uplink radio resource to the first user equipment at least partly based on said predicted load.
