Abstract:
A method comprising the step of transmitting a time slot comprising two or more replications of a base pattern defining positions of data symbols, synchronization symbols and pilot symbols for a first number of sub-channels corresponding to a first bandwidth,wherein the base pattern comprises an initial pattern identifying positions of data symbols, synchronization symbols and pilot symbols for the first number of sub-channels corresponding to the first bandwidth, and an extension pattern appended to the initial pattern, the extension pattern comprising one or more follow on patterns consecutively joined so that they identify positions of data symbols, synchronization symbols and pilot symbols for the first number of sub-channels corresponding to the first bandwidth, and wherein the two or more replications in combination define positions of data symbols, synchronization symbols and pilot symbols for a second number of sub-channels corresponding to a second bandwidth.
