Abstract

In order to allow for accommodating different services having different demands while suppressing interference, a first apparatus of the present invention includes: an information obtaining unit configured to obtain guard band information which indicates a guard band within a frequency band including a first band with a first subcarrier spacing and a second band with a second subcarrier spacing; and a communication processing unit configured to transmit the guard band information to a terminal apparatus.

What is claimed is: 
     
         1 . A first base station comprising:
 a memory storing instructions; and   one or more processors configured to execute the instructions to:
 transmit guard band information, to a User Equipment (UE), in a message related to establishing a Radio Resource Control (RRC) connection, wherein 
   the guard band information comprises a value indicating a width of the guard band,   the value is represented by plurality bits, and   if the value is 0, then the guard band information indicates absence of a guard band.
