Wireless base station, wireless apparatus, wireless control apparatus, wireless communication system, communication method, and wireless terminal

A wireless apparatus for a wireless base station configured to communicate with a wireless terminal, the wireless apparatus comprising:

• a processor configured to perform first signal processing, the first signal processing including wireless signal processing among signal processing of the wireless base station;
• an interface configured to perform signal transfer to and from a wireless control apparatus, the wireless control apparatus being configured to perform second signal processing different from the first signal processing;
• and
• a first transmitter configured to notify the wireless control apparatus of first information relating to the first signal processing.

A wireless control apparatus for a wireless base station configured to communicate with a wireless terminal, the wireless control apparatus comprising:

• a processor configured to perform second signal processing, the second signal processing being a part of signal processing in the wireless base station;
• an interface configured to perform signal transfer to and from a wireless apparatus, the wireless apparatus being configured to perform first signal processing different from the second signal processing;
• and
• a second transmitter configured to notify the wireless apparatus of second information relating to the second signal processing.

A wireless communication system comprising:

• a wireless terminal;
• and
• a wireless base station configured to communicate with the wireless terminal, the wireless base station comprising:
• a wireless apparatus configured to perform first signal processing which includes wireless signal processing among signal processing of the wireless base station;
• a wireless control apparatus configured to perform second signal processing different from the first signal processing;
• and
• a transmitter that includes at least any of a first transmitter and a second transmitter, the first transmitter being configured to notify the wireless control apparatus of first information relating to the first signal processing, the second transmitter being configured to notify the wireless apparatus of second information relating to the second signal processing.

A communication method performed in a wireless base station for communicating with a wireless terminal, the wireless base station including a wireless apparatus and a wireless control apparatus, the method comprising:

• performing, by the wireless apparatus, first signal processing that includes wireless signal processing among signal processing of the wireless base station;
• performing, by the wireless control apparatus, second signal processing different from the first signal processing;
• and
• performing, by a transmitter, at least any of first notification processing and second notification processing, the first notification processing being configured to notify the wireless control apparatus of first information relating to the first signal processing, the second notification processing being configured to notify the wireless apparatus of second information relating to the second signal processing.
