摘要： A method for noise rise estimation in a wireless communication system comprises measuring (210) of received total wideband power of an antenna a plurality of times. An estimate of a noise floor measure is computed (212) based on at least a number of the measured received total wideband powers of the antenna. Interference whitening of a received signal is performed (214) per user for a multitude of users. A useful signal power per user after the interference whitening, preferably Frequency Domain Equalization, is determined (216). A noise rise measure per user is calculated (220), based at least on the useful signal power per user and the noise floor measure. The calculation in turn comprises compensation of the noise rise measure per user for the effects of the interference whitening. An arrangement for noise rise estimation is adapted for such a method. A radio base station comprises such an arrangement.

摘要： An RBS and a method performed by an RBS for scheduling uplink resources to at least one UEare provided. The RBS comprises at least two receiving antenna branches and the RBS is operable in aradiocommunication network.The method comprises receiving (110) transmissions from the at least one UE by means of the at least two receiving antenna branches; and determining (120) at least one parameter relating tosignal quality of the received transmissions. The method further comprises determining (130) a diversity gain of the at least two receiving antenna branches, wherein the diversity gain is determined based on the determined parameter(s); and scheduling (140) uplink transmissions for the at least one UE based on the determined diversity gain.
