Synchronous signal design and cell search algorithm for blank state

摘要

Aspects of this disclosure provide techniques for the design of synchronization signals for other blank state OFDM-based systems, such as narrowband operation and extended component carrier (eCC) systems. An exemplary method is provided for operations that may be performed by a BS to generate and transmit a dual layer PSS and correspondingly techniques for the UE to detect the dual layer PSS. The PSS may be generated utilizing a binary code cover and at least one sequence applied to some symbols in one or more subframes of the frame.
