Publication number: 20230344687Abstract: Systems and methods for selecting subcarriers to be used for sub-Physical Resource Block (PRB) transmission and, in some embodiments, for mapping Demodulation Reference Signals (DMRS) to resources on the selected subcarriers are disclosed. In some embodiments, a method of operation of a radio node for providing sub-PRB transmission comprises selecting two adjacent subcarriers from a set of three 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 only two adjacent subcarriers out of the set of three allocated subcarriers with Discrete Fourier Transform (DFT) spread length of 2. In some embodiments, the selection is such that the selected adjacent subcarriers varies, e.g., from one cell to another. In doing so, interference is distributed.Type: ApplicationFiled: June 29, 2023Publication date: October 26, 2023Inventors: Yi-Pin Eric Wang, Anders K.
