Abstract
A method, system, and device for resource block (RB) indexing in a user equipment (UE) is provided. In an embodiment, the method includes obtaining, at the UE, a UE-independent frequency reference point. The method also includes determining, by the UE, a UE-independent index of an RB according to the UE-independent frequency reference point.

A method, comprising:
- receiving, by an apparatus, remaining system information (RMSI) indicating a relative frequency distance;
- obtaining, by the apparatus, a frequency reference point based on a starting subcarrier of a reference synchronization signal block (SSB) and the relative frequency distance;
- and
- determining, by the apparatus, a first reference resource block (RB) associated with a first subcarrier spacing based on the frequency reference point, wherein an index of the first reference RB is 0, and wherein a starting subcarrier of the first reference RB includes the frequency reference point.
