Wireless communication device, wireless communication terminal and wireless communication method

A wireless communication terminal, comprising:

• at least one antenna;
• a receiver coupled to the antenna and configured to receive a packet;
• a transmitter coupled to the antenna and configured to transmit a packet;
• a communication processor coupled to the receiver and the transmitter;
• a network processor coupled to the communication processor and configured to transmit data to the communication processor and receive data from another device;
• and
• a memory coupled to the network processor and configured to cache first data from the other device,
• wherein, through the antenna, the receiver is configured to receive a first field, receives at least one of a plurality of second fields having been multiplexed and transmitted, and decode the one of the second fields to obtain a frame in a case where first information identifying the own device is not set in the first field, and
• the communication processor is configured to control so as to suppress access to a wireless medium during duration indicated by a value set in the frame, and
• during a period of time when the access to the wireless medium is not suppressed, the transmitter is configured to transmit the first data cached in the memory or information based on the first data through the antenna.

A wireless communication method by a wireless communication terminal, comprising:

• caching first data from another device in a memory;
• at least one antenna;
• receive a first field and receives at least one of a plurality of second fields having been multiplexed and transmitted;
• decoding the one of the second fields to obtain a frame in a case where first information identifying the own device is not set in the first field;
• controlling so as to suppress access to a wireless medium during duration indicated by a value set in the frame;
• and
• transmitting, during a period of time when the access to the wireless medium is not suppressed, the first data cached in the memory or information based on the first data.
