摘要

The present invention discloses a wireless LAN system and a signal collision avoidance method for the wireless LAN system, which can avoid the collision of signals between a wireless LAN system initiating communication at fixed intervals and a wireless LAN system initiating communication after waiting for the vacancy of a channel. According to the present invention, when it is recognized that there is a no signal section between a downlink phase and an uplink phase upon scheduling of a communication frame, a scheduler part 6 performs scheduling for putting a NAV setup signal, which covers the no signal section, behind the downlink phase in accordance with instructions from a NAV setup signal generating part 8, and transmits the same. It can prevent any station in an IEEE802.11a wireless LAN system from transmitting data in the no signal section, and hence avoid the collision of signals within the period of the uplink phase.
