Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1 , it is a schematic flowchart of a signal transmission method provided by an embodiment of the present invention. This method is applied to the terminal.

Specifically, the method can be specifically applied to a terminal having the hardware structure shown in FIG. 2 . The terminal includes: a processor, a wireless connection network module WCN IC, a first radio frequency front end, a second radio frequency front end, a first antenna 1 and a second antenna 2; wherein the processor is connected to the wireless connection network module, and the first radio frequency The front ends are respectively connected to the wireless connection network module and the first antenna 1 , and the second RF front ends are respectively connected to the wireless connection network module and the second antenna 2 .

It should be noted that the processor plays a controlling role.

The wireless connection network module is a module that integrates Bluetooth/WiFi transceiver function, power amplification function, receiving low noise amplifier function and some radio frequency switching functions.

The RF front-end is a device close to the antenna part, and the RF front-end includes a transmit path and a receive path. The RF front end usually includes: amplifiers, filters, frequency converters, and some RF connections and matching circuits. Here, optionally, the RF front-end may be additionally provided with a power amplification function and a RF front-end circuit with receiving low-noise amplifier, filtering and switching functions.

It should also be noted that FIG. 2 only takes two radio frequency links as an example, and is not limited to two in practical application.

In addition, the above modules only represent modules that realize a certain function, and the specific form is not limited, and may be an independent packaged integrated circuit, or a combination of separate components.

The implementation process of the method of the present invention will be specifically described below with reference to FIG. 1 .

Step 101, when the first communication module and the second communication module of the terminal are turned on at the same time, determine the first target radio frequency link according to the first radio frequency link currently occupied by the transmission signal of the first communication module, Both the first radio frequency link and the first target radio frequency link are one of at least two radio frequency links for the second communication module to transmit signals.

In this step, specifically, the current working state of the terminal can be obtained through the processor on the terminal to determine whether the first communication module and the second communication module are turned on at the same time.

Here, the first communication module supports the first short-range wireless communication technology, and the second communication module supports the second short-range wireless communication technology and the multiple-input multiple-output technology.

Optionally, the first short-range wireless communication technology is Bluetooth technology, and the second short-range wireless communication technology is WiFi technology. Correspondingly, the first communication module is a Bluetooth module supporting Bluetooth technology, and the second communication module is a WiFi module supporting WiFi MIMO technology.

Step 102: Determine a second target radio frequency link according to the first target radio frequency link, where the first target radio frequency link and the second target radio frequency link are both of the at least two radio frequency links. a radio frequency link, and the second target radio frequency link is different from the first target radio frequency link.

Here, the terminal includes at least two radio frequency links. Since the second communication module supports the multiple-input multiple-output technology, the at least two radio frequency links can be used for the second communication module to transmit signals.

In addition, the second communication module selects a main radio frequency link from at least two radio frequency links according to the uplink signal quality of the transmitted signal, and the main radio frequency link has the best uplink performance of the signal transmitted by the second communication module the RF link, and the other links are used as secondary RF links. The second communication module only performs uplink signal transmission through the primary radio frequency link, and performs downlink signal transmission through all radio frequency links (primary and secondary).

For example, the second communication module is a WiFi module supporting WiFi MIMO technology, the first communication module is a Bluetooth module, and the WiFi module will select one of the at least two radio frequency links with the best uplink performance according to the uplink signal quality of the WiFi signal transmitted by the WiFi module The RF link of the WiFi module is used as the main RF link. The uplink signal of the WiFi module is only transmitted through the main RF link, and the downlink signal is transmitted through all RF links (primary and secondary). Taking Figure 2 as an example, the first antenna 1 is used as the main RF link. If the radio frequency link is used, the uplink signal of the WiFi module is only transmitted through the first radio frequency front end, and the downlink signal is transmitted through both the first radio frequency front end and the second radio frequency front end.

Here, the Bluetooth module (which does not support MIMO technology) selects one radio frequency link, and both uplink and downlink signals are transmitted only from one radio frequency link.

Here, the second target radio frequency link and the first target radio frequency link are both radio frequency links in the at least two radio frequency links. In this way, the first communication module and the second communication module can avoid the subsequent transmission of signals by the first communication module and the second communication module. The same radio frequency channel is used at all times, so as to avoid the introduction of time slot distinction and the decrease of the uplink and downlink throughputs of the first communication module and the second communication module, and ensure that the respective uplink and downlink throughputs of the first communication module and the second communication module are mutually exclusive. Not affected, the communication stability of the first communication module and the transmission rate of the second communication module are improved.

Step 103: Control the first communication module to perform signal transmission through the first target radio frequency link, and control the second communication module to perform uplink signal transmission through the second target radio frequency channel.

In the signal transmission method provided by the embodiment of the present invention, when the first communication module and the second communication module of the terminal are turned on at the same time, the first target is determined according to the first radio frequency link occupied by the current transmission signal of the first communication module The radio frequency link, the first radio frequency link and the first target radio frequency link are all one of at least two radio frequency links for the second communication module to transmit signals; according to the first target radio frequency link, determine the second target radio frequency link, the first target radio frequency link and the second target radio frequency link are radio frequency links in at least two radio frequency links, and the second target radio frequency link is different from the first target radio frequency link; controlling the first target radio frequency link The communication module performs signal transmission through the first target radio frequency link, and controls the second communication module to perform uplink signal transmission through the second target radio frequency path, so that the first communication module and the second communication module can be prevented from transmitting The same radio frequency channel is used for the signal, so as to avoid the introduction of time slot distinction and bring down the uplink and downlink throughput of the first communication module and the second communication module, and ensure that the uplink and downlink throughputs of the first communication module and the second communication module are mutually compatible. The communication stability of the first communication module and the transmission rate of the second communication module are improved.

Based on the embodiment shown in FIG. 1, as an optional implementation manner, step 101 may include:

In the case that the first radio frequency link is the main radio frequency link for the second communication module to transmit signals, the main radio frequency link is determined as the first target radio frequency link, and the main radio frequency link is Based on the uplink transmission signal quality of the signal transmitted by the second communication module, the radio frequency link with the best uplink performance of the transmission signal is determined from the at least two radio frequency links.

It should be noted that, generally, when the first communication module is turned on, if due to hardware limitations, for example, due to the internal architecture of the wireless connection network module or the limitation of peripheral circuits, the first communication module, optionally, the Bluetooth module Only one link can be connected, and link switching cannot be realized, so the first communication module can only choose to occupy the main radio frequency link when transmitting signals.

In the above situation, since the first target radio frequency link finally occupied by the first communication module to transmit signals is the main radio frequency link for the second communication module to transmit signals, the first communication module and the second communication module share one For the radio frequency link, in order to avoid the problem that the uplink and downlink throughputs of the first communication module and the second communication module are reduced due to the above situation, correspondingly, step 102 of the method of the present invention may include:

Based on the uplink transmission signal quality of the signal transmitted by the second communication module, from the remaining radio frequency links other than the first target radio frequency link in the at least two radio frequency links, it is determined that the uplink performance of the transmission signal is the highest The optimal radio frequency link is determined as the second target radio frequency link.

That is to say, the main radio frequency link for transmitting signals, that is, the second target radio frequency link, is re-determined for the second communication module, so that the first communication module and the second communication module can use the same radio frequency path when transmitting signals, so that the To avoid the introduction of time slot distinction, the uplink and downlink throughputs of the first communication module and the second communication module are reduced, ensuring that the respective uplink and downlink throughputs of the first communication module and the second communication module are not affected by each other, and the first communication module is improved. The stability of module communication and the transmission rate of the second communication module.

Based on the embodiment shown in FIG. 1, as another optional implementation manner, step 101 may include:

In the case where the first radio frequency link is a secondary radio frequency link for the second communication module to transmit signals, based on the signal quality transmitted by the first communication module, from the at least two radio frequency chains The radio frequency link with the best performance of the signal transmitted by the first communication module determined in the path is determined as the first target radio frequency link, and the secondary radio frequency link is divided by the at least two radio frequency links based on the The uplink transmission signal quality of the signal transmitted by the second communication module is one of the remaining radio frequency links other than the radio frequency link with the best uplink performance of the transmission signal determined from the at least two radio frequency links.

Here, it should be noted that when the first communication module is turned on, if there is no hardware restriction, the secondary radio frequency link of the second communication module for transmitting signals will be preferentially occupied when initially transmitting the first signal.

Accordingly, step 102 of the method of the present invention may include:

If the first target radio frequency link is a secondary radio frequency link for the second communication module to transmit signals, determining the primary radio frequency link for the second communication module to transmit signals as the second target radio frequency link ;

In this step, if the first target radio frequency link is a secondary radio frequency link for the second communication module to transmit signals, that is, based on the signal quality of the signal transmitted by the first communication module, from the The radio frequency link with the best performance of the signal transmitted by the first communication module determined in the at least two radio frequency links is still the secondary radio frequency link for the second communication module to transmit signals, that is, for the second communication module. The main radio frequency link for transmitting signals and the first target radio frequency link for transmitting signals by the first communication module are not the same radio frequency link, which can prevent the first communication module and the second communication module from using the same radio frequency path when transmitting signals, This avoids the reduction of uplink and downlink throughput of the first communication module and the second communication module due to the introduction of time slot distinction, and the terminal does not need to re-determine the main radio frequency link for transmitting the second signal for the second communication module.

If the first target radio frequency link is the main radio frequency link for the second communication module to transmit signals, then based on the uplink transmission signal quality of the signal transmitted by the second communication module, from the at least two radio frequency chains Among the remaining radio frequency links in the road except the first target radio frequency link, the radio frequency link with the best uplink performance of the transmission signal is determined, and it is determined as the second target radio frequency link.

In this step, if the first target radio frequency link is the main radio frequency link for the second communication module to transmit signals, that is, based on the signal quality of the signal transmitted by the first communication module, from the The radio frequency link with the best performance of the signal transmitted by the first communication module determined in the at least two radio frequency links is the main radio frequency link for the second communication module to transmit signals. At this time, the terminal needs to remove the first target radio frequency In the remaining links other than the link, the primary radio frequency link for transmitting signals, that is, the second target radio frequency link, is re-determined for the second communication module, so as to prevent the first communication module and the second communication module from using the same link when transmitting signals. The radio frequency channel is used to avoid the introduction of time slot distinction and the decrease in the uplink and downlink throughput of the first communication module and the second communication module, so as to ensure that the respective uplink and downlink throughputs of the first communication module and the second communication module are not affected by each other. The communication stability of the first communication module and the transmission rate of the second communication module are improved.

Based on the embodiment shown in FIG. 1, as an optional implementation manner, the method of the present invention may further include:

controlling the second communication module to pass through the second target radio frequency link and the remaining radio frequency chains of the at least two radio frequency links except the first target radio frequency link and the second target radio frequency link channel for downlink signal transmission.

The implementation of this step can ensure that the second communication module performs downlink signal transmission, and uses a different radio frequency channel from that of the first communication module for signal transmission. The uplink and downlink throughput, thereby improving the communication stability of the first communication module and the transmission rate of the second communication module.

In the signal transmission method provided by the embodiment of the present invention, when the first communication module and the second communication module of the terminal are turned on at the same time, the first target is determined according to the first radio frequency link occupied by the current transmission signal of the first communication module The radio frequency link, the first radio frequency link and the first target radio frequency link are all one of at least two radio frequency links for the second communication module to transmit signals; according to the first target radio frequency link, determine the second target radio frequency link, the first target radio frequency link and the second target radio frequency link are both radio frequency links in at least two radio frequency links, and the second target radio frequency link is different from the first target radio frequency link; controlling the first target radio frequency link A communication module transmits signals through the first target radio frequency link, and controls the second communication module to transmit uplink signals through the second target radio frequency path. In this way, the first communication module and the second communication module can be prevented from The same radio frequency channel is used when transmitting signals, so as to avoid the introduction of time slot distinction and reduce the uplink and downlink throughput of the first communication module and the second communication module, and ensure that the respective uplink and downlink throughputs of the first communication module and the second communication module are mutually compatible. They are not affected, and the stability of the communication of the first communication module and the transmission rate of the second communication module are improved.
