Then performing the steps of determining a first load measure based on the interference suppressed received signals and the estimated reference received total wideband power, and determining a second load measure based on the interference suppressed received signals, the estimated reference received total wideband power and on the estimated neighbor cell interference. | 10-30-2014 |
20140334455 | UPLINK SCHEDULING WHEN USING INTERFERENCE SUPPRESSION - 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. | 11-13-2014 |
