1. A method of operation of a radio node for providing sub-Physical Resource Block (sub-PRB) transmission, comprising:
selecting, based on a value resulting from a modulo 2 operation on a cell Identifier (ID) of a cell, adjacent subcarriers from a set of allocated subcarriers that are allocated for a sub-PRB transmission that uses Single Carrier Frequency Division Multiple Access (SC-FDMA) Pi/2 Binary Phase Shift Keying (BPSK) modulation using the adjacent subcarriers out of the set of allocated subcarriers with Discrete Fourier Transform (DFT) spread length of 2.
