Abstract

A concept for estimating interfering channels in a multicellular radio communication system including a plurality of base stations and at least one mobile station is suggest, wherein pilot signals are transmitted from the base stations to at least a mobile station, additional pilot sequences are generated, a pattern is provided which defines a rule for distributing the pilot sequences to the base stations, the pilot sequences are modulated and superposed onto said pilot signals, and a pilot signal received at a mobile station is used for estimating interferences in the communication channel from the base station which transmits the pilot signal.
