Abstract
Techniques may be used to generate a multi-length Zero Tail (ZT) Discrete Fourier Transform-spread Orthogonal Frequency Domain Modulation (DFT-s-OFDM) signal for transmission. A selected allocation of frequency resources may include a plurality of subbands. Subbands may be assigned to wireless transmit/receive units (WTRUs) (i.e., users), and zero head length and zero tail length may be assigned to each of the assigned subbands according to a pattern to combat inter-symbol interference (ISI). The ZT DFT-s OFDM signal may generated for transmission over the assigned subbands in accordance with the assigned zero head length and the assigned zero tail length.
