Silent mode indication method, data transmission method and device in silent mode

Abstract

Embodiments of the present invention provide a silent mode indication method, a data transmission method and device, and a system in the silent mode, so as to make full use of frequency band resources and increase the transmission rate of the system. The method includes: sending a silent element message to the stations in the basic service set, so that the stations in the basic service set know the available working frequency band during the silent time according to the silent element message, and do not send data or use the frequency band during the silent time. Data can be transmitted in the working frequency band. Compared with the prior art instructing the stations in the basic service set to prohibit the use of the entire working frequency band during the silent time, the silent mode indication method provided by the embodiment of the present invention enables the stations in the basic service set to send data on the available working frequency band during the silent time, making full use of The frequency band resource is increased, and the transmission rate of the whole system is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a silent mode indication method, a data transmission method and a device in the silent mode. Background technique [0002] A basic service set (Basic Service Set, BSS) is a basic component of a wireless local area network, and is composed of stations (Station, hereinafter abbreviated as STA) within a certain coverage area and having certain associations. The most basic form of station association in the BSS is that terminals or stations directly communicate with each other in an ad hoc network. The BSS in the most basic form of association is also called an Independent Basic Service Set (IBSS). IBSS is not common in the form of station association in BSS. The common form of station association in BSS is that each STA is associated with a central site dedicated to managing the basic service set. The central site is called an access point (AP, Access Point), and the BSS built...

AI Technical Summary

Problems solved by technology

[0013] After long-term research and practice, the inventor of this case found that the defect of the silence indication method provided by the above prior art is that once the STA receives the silence element, the STA will remain silent on the entire working frequency band, but in fact, not all silences require Measure the interference and noise on the entire working frequency band. In this case, the part of the working frequency band that does not need to be measured can still be used. Therefore, the silent indication method provided by the prior art does not have a high utilization rate of the working frequency band.
