CLAIMS
1. A communication system comprising: a communication terminal device; and
base station devices configuring cells capable of radio communication with said communication terminal device,
wherein
said cells include
a macro cell having a coverage in which communication with said communication terminal device is enabled, said coverage being relatively large, and
a small cell provided such that at least a part of said coverage of said small cell overlaps the coverage of said macro cell, said coverage of said small cell being relatively small, and
when said communication terminal device is connected to said macro cell and said small cell, upon receipt of information for small cells directed to said small cell from a higher-layer device, at least one cell of said macro cell and said small cell notifies said communication terminal device connected with said at least one cell of said information for small cells.
2. The communication system according to claim 1, wherein at least one cell of said macro cell and said small cell notifies said communication terminal device of broadcast indication information before said communication terminal device is notified of said information for small cells, said broadcast indication information indicating that said information for small cells has been broadcast.

3. The communication system according to claim 2, wherein said small cell
notifies said communication terminal device of said broadcast indication information.
4. The communication system according to claim 2, wherein said small cell
notifies said communication terminal device of said broadcast indication information via
said macro cell.
5. The communication system according to claim 2, wherein said macro cell
notifies said communication terminal device of said broadcast indication information.
