Abstract
A Method for increasing coverage and robustness against frequency offsets in wireless networks, user device and computer program productsIn the method, a user device (171) that wirelessly communicates with a base station (172) through a wireless network employing a Single Carrier-Frequency Division Multiple Access, SC-FDMA, comprises: applying a number of calculated repetitions of a block of complex information symbols prior to a SC-FDMA modulator (176), said number of repetitions being an integer submultiple of a number of subcarriers scheduled for uplink transmission according to the expression: NscUL=L×M with L and M integers; and applying, when mapping to scheduled resources in the SC-FDMA modulator (176), a frequency shift equal to a subcarrier width multiplied by one half of said number of repetitions.
