Abstract

The present application is at least directed to an apparatus on a 5G network. The apparatus includes a non-transitory memory including instructions stored thereon for performing configuration of an initial access signal in the 5G network. The apparatus also includes a processor, operably coupled to the non-transitory memory, capable of executing an instruction of monitoring transmission of a downlink sweeping subframe including a beam sweeping block carrying a downlink initial access signal. The processor is capable of also executing the instruction of detecting the downlink initial access signal carrying a synchronization signal. The processor is capable of also executing the instruction of determining, based on the synchronization signal, an identity of the beam sweeping block associatedwith the downlink initial access signal. The present application is also directed to an apparatus configured to perform downlink synchronization of a cell in the 5G network.
