Physical (PHY) layer solutions to support use of mixed numerologies in the same channel

A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in a cell. The PSS and SSS may use a first numerology. Further, the first numerology may have a first subcarrier spacing, while other resou...

More Information
Summary:A wireless transmit/receive unit (WTRU) may receive a first signal including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in a cell. The PSS and SSS may use 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 PSS or the SSS use a second numerology with a different subcarrier spacing than the first numerology. In addition, the WTRU may synchronize to a timing of the cell based on the PSS and SSS. Also, the WTRU may receive a second signal in the cell, and the second signal may use 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.
