Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a signal transmission method according to an embodiment of the present invention. The method is applied to the terminal.
Specifically, the method is applicable to a terminal having a hardware configuration as shown in fig. 2. The terminal includes: the system comprises 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; the processor is connected with the wireless connection network module, the first radio frequency front end is respectively connected with the wireless connection network module and the first antenna 1, and the second radio frequency front end is respectively connected with the wireless connection network module and the second antenna 2.
It should be noted that the processor plays a role of control.
The wireless connection network module is a module integrating the functions of a Bluetooth/WiFi transceiver, a power amplification function, a low noise amplification function and a plurality of radio frequency switches.
The radio frequency front end is a device close to the antenna part and comprises a transmitting path and a receiving path. The radio frequency front end typically comprises: amplifiers, filters, frequency converters, and some rf connections and matching circuits. Here, the rf front end may optionally be added with a power amplification function and an rf front end circuit that receives low noise amplification, filtering and switching functions.
It should be noted that fig. 2 only takes two rf links as an example, and is not limited to two in practical application.
The module is only a module for realizing a certain function, and the specific form is not limited, and the module may be an independently packaged integrated circuit, or may be a discrete component built combination, or the like.
The process of the invention is described in detail below with reference to FIG. 1.
In this step, specifically, the current working state of the terminal may be obtained through a processor on the terminal to determine whether the first communication module and the second communication module are simultaneously turned on.
Here, the first communication module supports a first short-range wireless communication technology, and the second communication module supports a second short-range wireless communication technology and a multiple-input multiple-output technology.
Optionally, the first short-range wireless communication technology is a bluetooth technology, and the second short-range wireless communication technology is a 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.
Here, the terminal includes at least two radio frequency links, and the at least two radio frequency links are used for the second communication module to transmit signals because the second communication module supports the mimo technology.
And 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 signals transmitted by the second communication module, wherein the main radio frequency link is the radio frequency link with the optimal uplink performance of the signals transmitted by the second communication module, and other links are used as secondary radio frequency links. The second communication module only carries out uplink signal transmission through the main radio frequency link and carries out downlink signal transmission through all the radio frequency links (primary and secondary).
For example, the second communication module is a WiFi module supporting a WiFi MIMO technology, the first communication module is a bluetooth module, the WiFi module may select one radio frequency link with the best uplink performance from at least two radio frequency links as a main radio frequency link according to the uplink signal quality of the WiFi signal transmitted by the WiFi module, the uplink signal of the WiFi module is transmitted only through the main radio frequency link, and the downlink signal is transmitted through all radio frequency links (primary and secondary), taking fig. 2 as an example, the first antenna 1 is used as the main radio frequency link, then the uplink signal of the WiFi module is transmitted only 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 (not supporting MIMO technology) selects one rf link, and both uplink and downlink signals are transmitted from only one rf link.
Here, the second target radio frequency link and the first target radio frequency link are both radio frequency links of the at least two radio frequency links, so that the first communication module and the second communication module can be prevented from using the same radio frequency channel during subsequent signal transmission, thereby avoiding the reduction of uplink and downlink throughputs of the first communication module and the second communication module caused by the introduction of time slot differentiation, ensuring that the respective uplink and downlink throughputs of the first communication module and the second communication module are not influenced, and 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, under the condition that a first communication module and a second communication module of a terminal are simultaneously turned on, a first target radio frequency link is determined according to a first radio frequency link occupied by a current transmission signal of the first communication module, and 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; determining a second target radio frequency link according to the first target radio frequency link, wherein 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; the first communication module is controlled to transmit signals through the first target radio frequency link, and the second communication module is controlled to transmit uplink signals through the second target radio frequency channel, so that the situation that the first communication module and the second communication module use the same radio frequency channel when transmitting signals can be avoided, the situation that the uplink throughput and the downlink throughput of the first communication module and the second communication module are reduced due to the fact that time slot distinguishing is introduced is avoided, the fact that the uplink throughput and the downlink throughput of the first communication module and the second communication module are not influenced, and 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:
and under the condition that the first radio frequency link is a main radio frequency link for the second communication module to transmit signals, determining the main radio frequency link as a first target radio frequency link, wherein the main radio frequency link is a radio frequency link with optimal uplink performance of transmission signals determined from the at least two radio frequency links on the basis of the uplink transmission signal quality of the signals transmitted by the second communication module.
It should be noted that, generally, when the first communication module is turned on, if the first communication module, optionally the bluetooth module, is only connected to one link due to hardware limitation, for example, limitation of an internal architecture of the wireless connection network module or limitation of a peripheral circuit, and cannot implement link switching, the first communication module only occupies the main radio frequency link when selecting transmission signals.
In the foregoing 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 radio frequency link, and in order to avoid the problem of the decrease in the uplink throughput and the downlink throughput of the first communication module and the second communication module caused by the foregoing situation, correspondingly, step 102 of the method of the present invention may include:
and determining a radio frequency link with the optimal uplink performance of the transmission signal from the rest of the at least two radio frequency links except the first target radio frequency link based on the uplink transmission signal quality of the signal transmitted by the second communication module, and determining the radio frequency link as a second target radio frequency link.
That is to say, the main radio frequency link, that is, the second target radio frequency link, for transmitting the signal is determined again for the second communication module, so that the first communication module and the second communication module can be prevented from using the same radio frequency channel when transmitting the signal, thereby avoiding the reduction of the uplink throughput and the downlink throughput of the first communication module and the second communication module caused by introducing time slot differentiation, ensuring that the uplink throughput and the downlink throughput of the first communication module and the second communication module are not influenced, and improving the communication stability of the first communication module 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:
and in the case that the first radio frequency link is a secondary radio frequency link for the second communication module to transmit signals, determining a radio frequency link with the best performance of signals transmitted by the first communication module, which is determined from the at least two radio frequency links, as a first target radio frequency link based on the quality of signals transmitted by the first communication module, wherein the secondary radio frequency link is one of the remaining radio frequency links, except for a radio frequency link with the best performance of signals transmitted by the second communication module, which is determined from the at least two radio frequency links, based on the quality of signals transmitted by the first communication module.
Here, it should be noted that, when the first communication module is turned on, if there is no hardware limitation, the secondary rf link for the second communication module to transmit signals is preferentially occupied when the first signal is transmitted initially.
Accordingly, step 102 of the method of the present invention may comprise:
if the first target radio frequency link is a secondary radio frequency link for the second communication module to transmit signals, determining a primary radio frequency link for the second communication module to transmit signals as a second target radio frequency link;
in this step, if the first target rf link is a secondary rf link for the second communication module to transmit signals, that is, based on the signal quality of the signals transmitted by the first communication module, the rf link with the best performance for the signals transmitted by the first communication module determined from the at least two rf links is still the secondary rf link for the second communication module to transmit signals, namely, the main radio frequency link for the second communication module to transmit signals and the first target radio frequency link for the first communication module to transmit signals are not the same radio frequency link, this avoids the use of the same rf path for the first and second communication modules in transmitting signals, therefore, the reduction of the uplink and downlink throughput of the first communication module and the second communication module caused by the introduction of time slot differentiation is avoided, and the terminal does not need to determine a main radio frequency link for transmitting the second signal for the second communication module again.
If the first target radio frequency link is a main radio frequency link for the second communication module to transmit signals, determining a radio frequency link with the optimal uplink performance of transmission signals from the remaining radio frequency links except the first target radio frequency link in the at least two radio frequency links based on the uplink transmission signal quality of the signals transmitted by the second communication module, and determining the radio frequency link as a second target radio frequency link.
In this step, if the first target rf link is a main rf link for the second communication module to transmit signals, that is, based on the signal quality of the signals transmitted by the first communication module, the rf link with the best performance of the signals transmitted by the first communication module, which is determined from the at least two rf links, is the main rf link for the second communication module to transmit signals, at this time, the terminal needs to re-determine the main rf link for the second communication module, that is, the second target rf link, from the remaining links except the first target rf link, so as to avoid the first communication module and the second communication module using the same rf channel when transmitting signals, thereby avoiding introducing timeslot differentiation to cause a decrease in uplink and downlink throughput of the first communication module and the second communication module, and ensuring that the uplink throughput and downlink throughput of the first communication module and the second communication module are not affected each other, the stability of the first communication module communication 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:
and controlling the second communication module to perform downlink signal transmission through the second target radio frequency link and the remaining radio frequency links except the first target radio frequency link and the second target radio frequency link in the at least two radio frequency links.
The implementation of the step can ensure that the second communication module carries out downlink signal transmission, and different radio frequency channels are used for transmitting signals with the first communication module, so that the respective uplink and downlink throughputs of the first communication module and the second communication module cannot be influenced during downlink signal transmission, and further, the communication stability of the first communication module and the transmission rate of the second communication module are improved.
In the signal transmission method provided by the embodiment of the present invention, under the condition that a first communication module and a second communication module of a terminal are simultaneously turned on, a first target radio frequency link is determined according to a first radio frequency link occupied by a current transmission signal of the first communication module, and 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; determining a second target radio frequency link according to the first target radio frequency link, wherein 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; the first communication module is controlled to transmit signals through the first target radio frequency link, and the second communication module is controlled to transmit uplink signals through the second target radio frequency channel, so that the situation that the first communication module and the second communication module use the same radio frequency channel when transmitting signals can be avoided, the situation that the uplink throughput and the downlink throughput of the first communication module and the second communication module are reduced due to the fact that time slot distinguishing is introduced is avoided, the fact that the uplink throughput and the downlink throughput of the first communication module and the second communication module are not influenced, and the communication stability of the first communication module and the transmission rate of the second communication module are improved.
