1. A method comprising: performing uplink data compression comprising: transforming, by a radio apparatus, a signal from a time-domain presentation into a frequency-domain presentation, wherein the signal is represented as frequency bin values; selecting a first group of adjacent frequency bins from the frequency-domain presentation; generating a first floating point number representation from values of the first group of adjacent frequency bins, wherein the first floating point number representation comprises a mantissa for each of the frequency bins' values of the first group of adjacent frequency bins, and wherein the first floating point number representation further comprises a first common exponent shared between the mantissas; outputting the mantissas of the first floating point number representation, and the value of the first common exponent shared between the mantissas of the first floating point number representation; and communicating the output mantissas and the value of the first common exponent toward a device for decoding using at least the output mantissa and the value of the first common exponent.
