Multi-frequency carrier aggregation WIFI data transmission method and device, and terminal equipment

Abstract

The invention relates to a multi-frequency carrier aggregation WIFI data transmission method and device and a terminal device. The multi-frequency carrier aggregation WIFI data transmission method comprises the following steps: when the WIFI networks covering the terminal contain a plurality of signal frequency bands, controlling the WIFI channel operating in the frequency bands in the terminal enter into the enabled state at the same time; establishing a communication link with each one of the signal frequency bands mentioned above; using the established communication links to transmit the data together. Thus, the transmission bandwidth is widened, and the data transmission rate is improved without increasing the antenna; meanwhile, according to the embodiment of the invention, the weight ratio of the first information flow of each communication link is calculated according to the signal transmission rate of each communication link; and the WIFI data to be transmitted is allocated to each communication link according to the first information flow weight ratio of each communication link; therefore, the information flow weight of each signal frequency band can be flexibly configured, the information capacity is maximized while ensuring the communication quality, and the spectrum resources can be better used.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-frequency carrier aggregation WIFI data transmission method, device and terminal equipment. Background technique [0002] With the rapid development of wireless technology, wireless fidelity (WIFI, Wireless Fidelity, also known as wireless broadband) can be seen almost everywhere, and the WIFI signal frequency bands covered in different places are also different. Specifically, it may cover 2.4GHZ frequency band or 5GHZ frequency band, or both frequency bands may exist. [0003] Among them, because the wavelength of the 2.4GHZ frequency band is relatively long, it has the advantages of strong anti-attenuation ability and long transmission distance; however, the 2.4GHZ frequency band is an unlicensed frequency band, and there are many devices using this frequency band, so it cannot guarantee sufficient stability. On the contrary, although the wavelength of ...
