METHOD, DEVICE, SYSTEM, AND NODE FOR PERFORMING NAV CONTROL ON NODE

摘要

The present invention discloses a method, a device and a system for performing NAV control on a node and a node. The method includes: updating a local NAV value to a preset first value when it is determined that a preset first field of a monitored MAC frame carries a first identity, wherein the first value is smaller than a current local NAV value and the MAC frame of which the preset first field carriers the first identity is transmitted by a TXOP responder after receiving a last MAC frame transmitted by a TXOP holder. The method, device, system and node may enable a hidden station to enter a channel access competition state timely, thereby solving a problem of regional discrimination of a station.
