Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, 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 making creative efforts belong to 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 implement...

Abstract

The invention discloses a signal transmission method, a signal transmission device and a terminal. The method is implemented in a terminal, and the terminal comprises a first WIFI antenna and a secondWIFI antenna which are used for transmitting a WIFI 5G signal, and an air interface antenna used for transmitting a 5G NR signal. The method comprises the steps of determining an air interface environment channel of a current transmission signal of the terminal; under the condition that the air interface environment channel comprises an N79 channel supporting an N79 frequency band in the 5G NR, transmitting a 5G NR signal through an air interface antenna, and transmitting a WIFI 5G signal through a second WIFI antenna; and under the condition that the air interface environment channel does not comprise the N79 channel, transmitting the 5G NR signal through the air interface antenna, and transmitting the WIFI 5G signal 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 LAN communication standard, the commonly used frequency range includes 5170-5835MHz (the actual planning 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 interference between t...
