摘要：
A method for generating a transmission slot includes receiving a transmission slot that includes a plurality of data regions and a plurality of control regions, in which each of the data regions include digital spread spectrum data. The method further includes substituting each of the plurality of data regions with at least one OFDM symbol having variable duration, in which each of the at least one OFDM symbol has a cyclic prefix extension (CPE).
