METHOD TO USE A SINGLE SIGNAL PROCESSING CHAIN FOR MULTIPLE NB-IOT CELLS ON CONSECUTIVE CARRIERS

Two methods of processing multiple Narrowband Internet of Things, NB-IoT, cells that occupy consecutive carriers, by a Radio Access Network, RAN, of a mobile network.The first method includes:1) shifting at least one first NB-IoT cell (5001, 5003) relative to an adjacent second NB-IoT cell (5002) to...

Summary:Two methods of processing multiple Narrowband Internet of Things, NB-IoT, cells that occupy consecutive carriers, by a Radio Access Network, RAN, of a mobile network.The first method includes:1) shifting at least one first NB-IoT cell (5001, 5003) relative to an adjacent second NB-IoT cell (5002) to align all subcarriers of the first and second NB-IoT cells (5001, 5002, 5003) to be mutually orthogonal; and2) using a first single fast Fourier transform, FFT, or first single inverse fast Fourier transform, iFFT, to process both the first and second NB-IoT cells.The second method includes:1) for a sequence of NB-IoT cells, every third NB-IoT cell is grouped into a single set, so as to form three sets of cells (1201, 1202, 1203), wherein each NB-IoT cell is separated by two other cells, and wherein all subcarriers of the NB-IoT cells in the single group are mutually orthogonal; and2) using a single FFT or a single iFFT by to process all the NB-IoT cells in a set formed by every third NB-IoT cell.
