Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] In one embodiment, a signal transmission method is provided, which is mainly aimed at signal transmission in a scenario where 5G NR and WIFI 5G coexist. Among them, 5G NR refers to a global 5G communication standard based on a new OFDM air interface design, and WIFI 5G is a WIFI communication protocol for 5G hotspots designed in IEEE 802.11, a wireless local area network communication standard.

[0031] The signal transmission method is implemen...

Abstract

The invention discloses a signal transmission method, device and terminal. The method is implemented in a terminal, and the terminal includes a first WIFI antenna for transmitting WIFI 5G signals, a second WIFI antenna, and an air interface antenna for transmitting 5G NR signals; the method includes: determining the air interface environment channel of the terminal currently transmitting signals; When the air interface environmental channel includes the N79 channel that supports the N79 frequency band in 5G NR, the 5G NR signal is transmitted through the air interface antenna, and the WIFI 5G signal is transmitted through the second WIFI antenna; in the case that the air interface environmental channel does not include the N79 channel, through The air interface antenna transmits 5G NR signals, and transmits WIFI 5G signals through the first WIFI antenna.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal transmission method, device, and terminal. Background technique [0002] With the rapid development of communication technology, mobile communication has entered the 5G era. In 5G NR, a global 5G (fifth-generation mobile communication) communication standard based on a new OFDM-based air interface design, the 5G spectrum has been expanded and multiple frequency bands between 3.3G and 5G have been added. Based on IEEE 802.11 The WIFI 5G of this wireless local area network communication standard, the commonly used frequency range includes 5170-5835MHz (actually planned but not yet used also includes 4910-5170Mhz), it can be seen that the N79 frequency band (4.4-5.0Ghz) in 5G NR and WIFI 5G The first channel of the 5.1G frequency band is very close, and in the scenario where 5G NR and WIFI 5G coexist, there will be more mutual interferen...
