Abstract

An information transmission source forms a transmission packet at a predetermined time unit into which a preamble is inserted and transmits it. The information reception target returns an acknowledge (ACK) packet or a not acknowledge (NACK) packet into which a preamble is inserted. A hidden terminal recognizes that the transmission path is used for data retransmission from when the NACK is received to when the next ACK is received to avoid collisions. Further, when there is transmission data at the information transmission source specified by a beacon signal, it is recognized that the transmission path is used until the next ACK is received. For example, in an ultra wide band communication method, access control is executed while avoiding collisions of communication communications and a retransmission control is executed.

Description

technical field [0001] The present invention relates to a wireless communication system for mutual communication between a plurality of wireless stations, a wireless communication device, a wireless communication method and a computer program, and in particular to a wireless communication system for realizing access control and retransmission control for avoiding communication conflicts , a wireless communication device, a wireless communication method and a computer program. [0002] More specifically, the present invention relates to a wireless communication system, a wireless communication device, a wireless communication method and a computer program for realizing access control and retransmission control for avoiding communication conflicts in an ultra-wideband communication system, and especially relates to A wireless communication system, a wireless communication device, a wireless communication method, and a computer program for providing access control and retransmiss...
