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.

Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a communications system, to determine a physical resource block (PRB) grid when a center frequency of a synchronization signal (SS) is inconsistent with a center frequency of a carrier. The method includes: receiving, by a terminal, an SS from a network device; determining, by the terminal, a first PRB grid based on the SS; receiving, by the terminal, first indication information from the network device, where the first indication information is used to indicate a first frequency offset between the first PRB grid and a second PRB grid; and determining, by the terminal, the second PRB grid based on the first PRB grid and the first frequency offset.
