Problems solved by technology

However, although this antenna switching solution can effectively improve the performance of the antenna, so that the LTE antenna will not be interfered by hand-held or minimal interference, it also causes the problem of increased production costs due to the need to add two additional DPDT switches. It will also increase the layout area of ​​the hardware channel, resulting in low integration, which brings great inconvenience to the entire RF front-end design

Embodiment 1

[0073] Please see attached Figure 5 , is a schematic flowchart of an antenna switching method provided in Embodiment 1 of the present invention. The method is suitable for a scenario where a 5G NR terminal in an NSA network performs antenna switching. In this scenario, the hardware path of the radio frequency front end performs and figure 2 The same antenna is combined, which greatly simplifies the hardware path. And the antenna layout for the image 3 Same. The method is performed by an antenna switching device, which can be implemented by software and / or hardware, and is integrated inside the terminal. The method specifically includes the following steps:

[0074] S101. Detect whether the terminal is in a handheld state; if the terminal is in a handheld state, proceed to step S102, and if the terminal is not in a handheld state, continue to perform step S101.

[0075] It should be noted that the present invention determines whether the terminal is currently in a handhe...

Embodiment 2

[0096] like Figure 7 As shown, the antenna switching method provided by the second embodiment of the present invention is based on the technical solution provided by the first embodiment, and further optimizes step S102 "detecting whether the first antenna working in the first network is interfered by hand-held." The explanations of terms that are the same as or corresponding to the above embodiments are not repeated here. which is:

[0097] Detecting whether signal attenuation occurs in the first antenna working on the first network;

[0098] When the signal attenuation of the first antenna occurs, calculate the signal attenuation of the first antenna;

[0099] Determine whether the signal attenuation is greater than or equal to a first threshold;

[0100] When the signal attenuation amount is greater than or equal to the first threshold, determining that the first antenna suffers from hand-held interference;

[0101] When the signal attenuation amount is less than the f...

Embodiment 3

[0113] Figure 8 This is a schematic flowchart of an antenna switching method provided by Embodiment 3 of the present invention. On the basis of Embodiment 1, this embodiment optimizes the method after step S103. The explanations of terms that are the same as or corresponding to the above embodiments will not be repeated here. For details, please refer to Figure 8 , the method includes:

[0114] S301. Detect whether the terminal is in a handheld state; if the terminal is in a handheld state, proceed to step S302, and if the terminal is not in a handheld state, continue to perform step S301.

[0115] S302. Detect whether the first antenna working in the first network is interfered by hand-held; if the first antenna is interfered by hand-held, go to step S303; if the first antenna is not interfered by hand-held, return to step S301 .

[0116] S303. Control the port of the second antenna working on the second network to call the code of the first network, and control the port...

Abstract

The invention discloses an antenna switching method, device, terminal and storage medium. The method includes detecting whether a terminal is in a handheld state; when the terminal is in a handheld state, detecting whether a first antenna working in a first network is interfered by the handheld ; When the first antenna is interfered by hand-held, control the port of the second antenna working in the second network to call the code of the first network, and control the port of the first antenna to call the code of the second network , so that the second antenna is switched to work in the first network, and the first antenna is switched to work in the second network. The antenna switching method, device, terminal and storage medium provided by the present invention simplifies the hardware design complexity of the radio frequency front-end by introducing a software switching method to replace the hardware switching method, reduces the layout area of ​​the hardware path, and improves the integration degree. It brings great convenience and scalability to the entire RF front-end design and performance improvement.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular, to an antenna switching method, apparatus, terminal, and storage medium. Background technique [0002] 5G, the fifth generation mobile communication technology, as the latest generation of cellular mobile communication technology, is an inevitable product of the continuous development of communication technology and the increasing number of mobile users. technology) evolution. The main advantage of 5G technology is that data transfer rates are much higher than previous cellular networks, up to 10Gbit / s, which is not only 100 times faster than previous 4G LTE cellular networks, but also faster than current wired internet; One advantage is lower network latency (i.e. faster response time), which is under 1 millisecond for 5G compared to 30-70 milliseconds for 4G. Due to faster data transmission, 5G communication has begun to shift from co...
