Claim:
1. A method for increasing coverage and robustness against frequency offsets in wireless networks, wherein at least one user device wirelessly communicates with at least one base station through a wireless network employing a Single Carrier-Frequency Division Multiple Access, SC-FDMA, the method comprising: applying, by said at least one user device a number of calculated repetitions of a block of complex information symbols prior to a SC-FDMA modulator said number of repetitions being an integer submultiple of a number of subcarriers scheduled for uplink transmission according to the expression: where N applying, by said at least one user device when mapping to scheduled resources in the SC-FDMA modulator a frequency shift equal to a subcarrier width multiplied by one half of said number of repetitions.
