1. A user equipment (UE) comprising:a transceiver configured to receive a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a primary broadcast channel (PBCH); and
a processor operably connected to the transceiver, the processor configured to decode cell identification information from at least the PSS and the SSS and to decode a master information block (MIB) from the PBCH;
wherein the PSS, the SSS, and the PBCH are time-division multiplexed,
wherein a same set of sequences are used for the PSS and the SSS regardless of carrier frequencies and sub-carrier spacing values for the PSS and the SSS,
wherein timing information within each radio frame is signaled via the PBCH, and
wherein the processor is further configured to use the timing information to determine a symbol timing of a received DL signal.
