DTF-S-OFDM AND OFDM WITH FREQUENCY DOMAIN CYCLIC PREFIX AND CYCLIC SUFFIX

摘要

Techniques, methods, procedures and apparatuses may be used involving frequency domain cyclic prefix (CP) and cyclic suffix (CS) for Orthogonal Frequency Domain Modulation (OFDM) and Discrete Fourier Transform-spread OFDM (DFT-s-OFDM) processing and transmission. A wireless transmit/receive unit (WTRU) may generate a frequency domain (FD) cyclic suffix (CS) based on a replication of a header of a data block. The WTRU may also generate an FD cyclic prefix (CP) based on a replication of a tail of the data block. The WTRU may then prepend the FD CP to the data block and append the FD CS to the data block. Accordingly, the WTRU may map the FD CP, the data block and the FD CS to corresponding inputs of an IDFT block. Then, the WTRU may transmit the FD CP, the data block and the FD CS.
