Improving Communication Efficiency

An apparatus comprising:

• at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause a radio apparatus to perform operations 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.

A computer program product embodied on a non-transitory computer readable medium readable by a computer and comprising program instructions which, when loaded into an apparatus, cause the apparatus to execute operations 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.
