Base station apparatus, communications method, and terminal device

A base station apparatus capable of simultaneously transmitting a plurality of control channels by frequency division multiplexing, the base station apparatus comprising:

• a processor;
• a baseband processing unit configured to obtain under control of the processor, distance information indicating a distance between the base station apparatus and another base station apparatus, and to configure under the control of the processor and based on the distance indicated by the obtained distance information, an upper limit count for the plurality of control channels to be transmitted simultaneously to a terminal device connected to the base station apparatus;
• and
• a radio frequency unit configured to transmit under the control of the processor and based on the configured upper limit count, the plurality of control channels to the terminal device.
