Claim of US Patent No. 10,798,727

1. Method for data transmission from a wireless device to a base node, wherein (i) the base node is part of a cellular network and is configured to support frequency division multiple access method, (ii) a frequency bandwidth, receivable by the base node, comprises a plurality of subcarriers, and (iii) the wireless device is camping on the base node, the method comprising the steps of:for the base node, assigning to the wireless device, a subcarrier of the plurality of subcarriers that is in a predetermined frequency range, and
transmitting data, from the wireless device, to the base node, (i) for a period of at least one data service session using only the assigned subcarrier, and (ii) using, for said data transmission, a first modulation scheme on the assigned subcarrier, wherein the first modulation scheme is a single subcarrier narrowband modulation scheme and is different from modulation schemes used, for groups of the subcarriers on said base node, by other wireless devices.
