Abstract
A transmission of information within a wireless cellular network may include a first and second group of samples. A first group (302b) of samples is created comprising at least a first (302a) and a last (402a) subgroup wherein the last subgroup is same as the first subgroup. A second group (302d) of samples is created. A transformed set of samples is produced by jointly transforming the created first and second group with a discrete Fourier transform (DFT). The transformed set of samples is expanded to produce an expanded set and the expanded set is transformed with an inverse discrete Fourier transform (IDFT) to produce an OFDM symbol with a fractional payload. The first group of samples is a reference signal (RS) which is known to the receiver before the transmission occurs while the second group of samples is information data.
