Abstract
A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The PSS and SSS may be received in a resource block of a cell and the resource block may have a first numerology. Further, the first numerology may have a first subcarrier spacing, while other resources of the cell at a same time as the resource block may have a second numerology with a different subcarrier spacing than the first numerology. In addition, the WTRU may determine synchronization based on the PSS and SSS. Also, the WTRU may receive a second signal in the cell, and the second signal may have the second numerology. Moreover, the WTRU may transmit user data. In a further example, the WTRU may search a frequency raster for the PSS and the SSS.
