发明名称 Wireless system, wireless communication apparatus and communication method
摘要 <p>A wireless communication system complying with a CSMA scheme includes one or more wireless communication apparatuses and a communication terminal that performs communication via the one or more wireless communication apparatuses. Each wireless communication apparatus includes: a transmission buffer configured to store a packet and output the packet according to transmission timing; a unit configured to determine a permissible delay time based on required quality for communication; and a control unit configured to determine the transmission timing, wherein, the control unit determines the transmission timing such that, after receiving a first packet, the wireless communication apparatus transmits the first packet after elapse of a waiting time that includes a period derived from a random number and the permissible delay time, and after receiving a response packet for the first packet, the wireless communication apparatus transmits a following second packet after elapse of a fixed period.</p>
