Abstract: A communication device performs transmitting, to a server, part or all of information being included in a user selection request, wherein the request requests an inference of quality of communication between the communication device and another communication device in accordance with user selection in Multi-User Multi Input Multi Output (MU-MIMO) communication, acquiring a result of the inference by the server from the server, and preforming MU-MIMO communication with the other communication device based on information acquired from the server.

Abstract: A communication apparatus capable of performing wireless communication conforming to the IEEE 802.11 standard includes a transmission unit configured to transmit a wireless frame having preambles and data fields of a physical layer (PHY). The preambles include a Legacy Short Training Field (L-STF), a Legacy Long Training Field (L-LTF), a Legacy Signal Field (L-SIG), an Extremely High Throughput Signal A Field (EHT-SIG-A), an EHT Short Training Field (EHT-STF), and an EHT Long Training Field (EHT-LTF). The EHT-SIG-A includes information about Preamble Puncturing in a case where a 320 MHz frequency bandwidth is to be used by the communication apparatus.
