Abstract

A radio communication device may include: a memory; and a processor configured to: determine a received radio signal including payload information from a plurality of mobile radio communication devices, wherein the payload information is mapped to a resource block via a plurality of cyclic shifts; for each mobile radio communication device of the plurality of mobile radio communication devices, determine a candidate cyclic shift applied to a respective payload information of the payload information, wherein the candidate cyclic shifts for the plurality of mobile radio communication devices are determined from a plurality of candidate cyclic shifts; and perform a noise power estimation using other candidate cyclic shifts of the plurality of candidate cyclic shifts, wherein the other candidate cyclic shifts are not determined as the candidate cyclic shifts.
