In Example 15, the subject matter of Example 14 can optionally include that the processing circuitry is configured to configure the transceiver to transmit higher layer signaling indicating numerologies, resource allocation and partition information via Master Information Block (MIB) carried by a physical broadcast channel (PBCH), a System Information Block (SIB) or UE-specific dedicated Radio Resource Control (RRC) signaling in a same RAT to each of the plurality of UEs.

In Example 16, the subject matter of one or any combination of Examples 14-15 can optionally include that the processing circuitry is configured to configure the transceiver to transmit numerologies, resource allocation and partition information via a dedicated carrier allocated for each of the RATs, and a dedicated downlink synchronization signal and physical broadcast channel (PBCH) is able to be received on each of the RATs.

In Example 17, the subject matter of one or any combination of Examples 14-16 can optionally include that at least one of the subcarrier spacing and symbol duration for each of the RATs is respectively specified as an integer number of a base subcarrier spacing or symbol duration.

In Example 18, the subject matter of one or any combination of Examples 14-17 can optionally include that the RATs comprise a first RAT comprising a larger subcarrier spacing and shorter symbol duration configured for a UE operating in a low latency mode and a second RAT comprising a smaller subcarrier spacing and longer symbol duration configured for a UE operating in a low energy mode.

In Example 19, the subject matter of one or any combination of Examples 14-18 can optionally include that a Transmission Time Interval (TTI) boundary between the RATs is common, and the RATs comprise a common reference TTI duration.
