1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
demodulating a payload of a physical broadcast channel (PBCH) transmission, using a demodulation reference signal (DMRS), in at least a second, in time, OFDM symbol, and a fourth, in time, OFDM symbol of a synchronization signal block (SSB), wherein the DMRS is located in same subcarriers in the second, in time, OFDM symbol and the fourth, in time, OFDM symbol and is interleaved in frequency with the payload of the PBCH;
wherein the SSB includes a primary synchronization signal (PSS) in a first, in time, OFDM symbol of the SSB and a secondary synchronization signal (SSS) in a third, in time, OFDM symbol of the SSB;
wherein the SSB spans only the first, in time, OFDM symbol, the second, in time, OFDM symbol, the third, in time, OFDM symbol and the fourth, in time, OFDM symbol;
wherein the PSS and the SSS span a same frequency spectrum and the PBCH spans a wider frequency spectrum than the PSS and the SSS.
