摘要： The present invention provides methods and arrangements 300 which are configured to determine a noise rise estimates in a radio access node of a Radio Network System 100 supporting Multi-Carrier High-Speed Packet Access transmission of user radio traffic between a radio access node and one or more User Equipments. The arrangement is provided with a combiner combining the estimated thermal noise power floors of all carriers of a set of carriers sharing the same antenna branch, into a single thermal noise power floor estimate, valid for all carriers in said set of carriers sharing the same analogue signal path. A noise rise determiner computes noise rise estimates as a quotient of the momentary received total wideband power of a carrier related to an analogue signal path, and said combined thermal noise power floor for said analogue signal path.
