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.

Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

Abstract: A method and apparatus are described. A wireless transmit/receive unit (WTRU) includes circuitry that determines transmission power levels associated with physical uplink shared channel (PUSCH) transmissions over a plurality of uplink component carriers. On a condition that maximum power scaling is required, the circuitry prioritizes providing power to a physical uplink control channel (PUCCH) over providing power to a physical uplink shared channel (PUSCH) having uplink control information (UCI) and prioritize providing power to the PUCCH and PUSCH having UCI over a PUSCH not having UCI. The circuitry transmits the PUCCH, the PUSCH having UCI or at least one PUSCH not having UCI over the plurality of uplink component carriers.
