In a method for enabling improved quality for noise limited uplink signals in a radio base station in a telecommunication system, said radio base station comprising a plurality of transceiver units, each comprising at least one receiver unit, adaptively allocating (S10) available transceiver units to enable parallel processing of an identified noise limited signal on at least two separate receiver units in the radio base station. And, combining (S20) the parallel processed noise limited calls to provide a received signal with improved signal to noise ratio.
