It should be noted that data transmission device in the embodiment of the present invention can for wireless access points (AP,
Wireless Access Point), or terminal.The embodiment of the present invention is described in detail by taking AP and terminal as an example.
Embodiment one
The embodiment of the present invention provides a kind of data transmission method, as shown in figure 3, be the corresponding data transmission method in the side AP,
This method may include:
When S101 and terminal carry out wireless network connection, AP sends n handshake to terminal, which uses
N carrier channel is used in request, which is the carrier channel with identical authentication service mode, the n carrier wave
Channel is corresponded with n handshake, wherein n >=1.
It should be noted that the premise that a kind of method of data transmission provided in an embodiment of the present invention is realized is AP and end
The connection of wireless network has been carried out in end, but before AP and terminal transmission data, which will also shake hands with terminal
Dialogue just can be with.
Specifically, the AP can send n handshake to the terminal, the n when AP and terminal carry out wireless network connection
For a handshake for requesting to send business datum using n carrier channel to terminal, which is with identical mirror
The carrier channel of method of service is weighed, which is one-to-one relationship with n handshake, wherein n >=1.
It is by 2 or more carrier units (CC, Component that carrier wave, which polymerize (CA, Carrier Aggregation),
Carrier it) condenses together to support that bigger transmission bandwidth, maximum aggregate bandwidth are 100MHz.Third generation affiliate meter
It draws (3GPP, 3rd Generation Partnership Project) tissue and the carrier aggregation technology is used for LTE-
Advanced network system.
In order to meet Wi-Fi higher throughput requirement, the embodiment of the present invention realizes the transmission for improving existing data
Bandwidth, and big bandwidth continuous frequency spectrum is very rare.Under the premise of not increasing frequency spectrum resource, while considering Wi-Fi net
Interference in network between different carrier channels, the present invention are that embodiment proposes and uses carrier aggregation technology in Wi-Fi network
To increase the transmission rate of Wi-Fi.Medium access control (MAC, Media Access Control) layer can specifically be used
Polymerization and the design of independent control channel, may be implemented to existing Wi-Fi network system structure back compatible.
In this way, in embodiments of the present invention, the number of the AP of n handshake of transmission to terminal can be one, it can also
To be n, the number of specific AP is determined by the function and structure of AP.If AP is the AP with carrier wave polymerizable functional,
AP in the embodiment of the present invention can be one, since an AP has carrier wave polymerizable functional, an AP can be sent
To terminal, which is used to request using n carrier channel to terminal transmission business datum n handshake.
It should be noted that AP and terminal can support carrier aggregation technology.But in embodiments of the present invention, AP
It is also possible to not support the AP of carrier wave polymerizable functional, at this point, to realize data transmission in realizing n carrier channel it is necessary to make
It is simultaneously that the terminal carries out data interaction with n AP.
Particularly, in embodiments of the present invention, terminal must support the terminal of carrier wave polymerizable functional, in this way, could reach
Increase the purpose of the transmission rate of Wi-Fi using carrier aggregation technology into Wi-Fi network.
The realization of the carrier wave polymerization in Wi-Fi is described below, i.e., is set using MAC layer polymerization and independent control channel
The content of meter.
