clean slate programming sync signal design and cell search algorithms

摘要

aspects of the present disclosure provide systems of techniques for creating synchronization signals for narrowband operation and other ofdm, clean-slate based systems, such as enhanced component carrier (ecc) systems. An exemplary method is provided for operations that may be performed by a BS to generate and transmit a double-layered powder, and correspondingly techniques for detecting the double-layered powder. pss may be generated using a binary coverage code and at least one sequence applied to multiple symbols within one or more subframes of a frame.
