Multiple symbol shift configuration

An apparatus for reducing inter symbol interference (ISI) and inter carrier interference (ICI) in transmissions between a sender and a recipient within a wireless communication network, wherein the apparatus comprising controlling circuitry configured to cause, for at least a first multicarrier symbol comprising a first subcarrier modulated with an original reference signal and multiplexed with a second subcarrier modulated with an original payload signal:

• application of a multiple symbol shift configuration on at least a second multicarrier symbol adjacent to the first multicarrier symbol by:
• repetition of the original reference signal and the original payload signal in the second multicarrier symbol on respective subcarriers;
• and
• application of a linear phase shift to each repeated reference signal and payload signal, wherein the same linear phase shift is used for both the repeated reference signal and the repeated payload signal.

A computer storage medium storing a computer program, comprising instructions which, when executed on at least one processor, cause the at least one processor to carry out a method for reducing inter symbol interference (ISI) and inter carrier interference (ICI) in transmissions between a sender and a recipient within a wireless communication network, at least a first multicarrier symbol comprising a first subcarrier modulated with an original reference signal and multiplexed with a second subcarrier modulated with an original payload signal, the method comprising:

• applying a multiple symbol shift configuration on at least a second multicarrier symbol adjacent to the first multicarrier symbol by:
• repeating the original reference signal and the original payload signal in the second multicarrier symbol on respective subcarriers;
• and
• applying a linear phase shift to the repeated reference signal and the repeated payload signal, the same linear phase shift being used for both the repeated reference signal and the repeated payload signal.
