Embodiment Construction

[0088] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0089] Related technologies can only perform bandwidth negotiation and determine available channels at the beginning of TXOP. Once TXOP starts, the transmission bandwidth cannot be changed (the actual transmission bandwidth is less than or equal to the requested bandwidth), resulting in low spectrum utilization; on the other hand, WLAN The interference of the unlicensed wireless network frequency bands at the location changes very quickly, resulting in frequency band resources changing from busy to idle within the TXOP. Related technologies cannot effectively use these idle resources, which also aff...

Abstract

The invention discloses a channel negotiation method, stations and a channel negotiation system. The channel negotiation method comprises the steps of transmitting channel reserving request information which comprises bandwidth expansion instructing information, wherein the bandwidth expansion indicating information is used for instructing a receiving station to perform bandwidth expansion feedback; and transmitting data to the receiving station according to the response bandwidth of the receiving station, wherein the response bandwidth of the receiving station is fed back by the receiving station in the channel reserving request information.

Description

technical field [0001] The invention relates to channel technology in the field of wireless communication, in particular to a channel negotiation method, station and system in a wireless local area network. Background technique [0002] At present, it is very common to use wireless local area networks (WLAN, Wireless Local Area Networks) for data communication, and the global demand for WLAN coverage is increasing day by day. The Institute of Electrical and Electronics Engineers industry specification IEEE802.11 has defined a series of standards such as 802.11a / b / g / n / ac to meet the ever-growing communication needs. Among them, dynamic channel detection threshold, as an alternative technology to improve channel reuse rate and solve network efficiency, has attracted extensive attention and research. [0003] In a common WLAN network, a basic service set (BSS, Basic Service Set) can be composed of an access point (AP, Access Point) and multiple stations (STA, Station) associat...
