Abstract
A method, system, and device to obtain a basic subcarrier spacing, or a channel bandwidth, or a maximum transmission bandwidth, or a usable subcarrier spacing set via a predefined mapping rule is provided. In an embodiment, a method in a network component to determine a system numerology includes determining, by the network component, one or more subcarrier spacing options from a candidate subcarrier spacing set that is associated with a carrier frequency band. The method also includes transmitting, by the network component, a signal indicating to one or more UEs one or more subcarrier spacing options from the candidate subcarrier spacing set.
