SYSTEM AND METHOD OF SINGLE-CARRIER LAYER SHIFTING FOR MULTIPLE-STREAM TRANSMISSION FACILITATING SIC IMPLEMENTATION

摘要

A system, method and node of single-carrier layer shifting for multiple- stream transmission in a network. Per-symbol layer shifting for multiple-stream transmission is implemented using DFTS-OFDM as an access technique. Code word-to-layer mapping is fixed within a DFTS-OFDM symbol and only shifted across consecutive DFTS-OFDM symbols. The method begins by receiving a multiple-stream transmission by a mapping module for transmission. The transmission includes a plurality of subframes and information carrying symbols transmitted on a plurality of layers. A per-symbol layer shifting scheme is then implemented on the transmission where layer shifting is conducted upon each symbol.
