Abstract

Provided are a base station device, a terminal device, and a communication method that, in an environment in which a plurality of frame formats are used in a multiplexed fashion, achieve a wireless access network in which beam scanning is performed appropriately. The base station device communicates with a terminal device, transmitting a synchronization signal and higher layer information indicating a subcarrier spacing. The subcarrier spacing is used to determine at least one of a quantity and an allocation of the resources used within a specific duration.
