Embodiment Construction

[0025] 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.

[0026] In one embodiment, a signal transmission method is provided, which is mainly aimed at signal transmission in the coexistence scenario of 5G NR and WIFI5G. 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.

[0027] The signal transmission method is impleme...

Abstract

The invention discloses a signal transmission method, device and a terminal. The method is applied to a terminal, and comprises the following steps: under the condition that an air interface network where the terminal is located currently is a 5G NR network, obtaining first WIFI 5G transmitting power of WIFI 5G signals currently transmitted by the terminal; under the condition that it is determined that the first WIFI 5G transmitting power does not meet the preset transmitting power safety condition, adjusting the first WIFI 5G transmitting power to be second WIFI 5G transmitting power meetingthe preset transmitting power safety condition; transmitting a WIFI 5G signal according to the second WIFI 5G transmitting power; and after starting to transmit the WIFI 5G signal, transmitting the 5G NR signal.

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 WIFI5G 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 5.1G of WIFI5G The first channel of the frequency band is very close, and in the scenario where 5G NR and WIFI5G coexist, there will be more mutual interference b...
