A radio communication station in a radio communication system having a plurality of radio communication devices, derives a quantisation parameter and transmits the quantisation parameter to the radio communication devices for use in subsequent quantisation of a channel state metric. The radio communication devices receive the quantisation parameter, determine a channel state metric, quantise the determined channel state metric by applying quantisation ranges indicated by the quantisation parameter, determine a data value indicative of the quantised channel state metric, and transmit a signal conveying the determined data value as a random access transmission.
