Furthermore, the conventional solution is susceptible to the peripheral environment, changing the antenna characteristics of the ANT0, resulting in greater impact on GNSS/WIFI.
According to the method, the function of 1T4R (1Transmit 4Radiation) is utilized, when LTE/NR and GNSS/WIFI work simultaneously, LTE/NR emission signals are controlled to be transmitted at different antennas (ANT0/1/2/3) in turn, and the GNSS/WIFI judges which LTE/NR antenna emits signals to be optimal for the SNR of the GNSS/WIFI through the SNR, so that the TX of the LTE/NR is controlled to work in the ANT0/1/2/3 to be the antenna with the relatively optimal SNR of the GNSS/WIFI.

In systems using different radio access technologies, names of devices having a base station function may be different, and for example, in an LTE network, the device is called an Evolved Node B (eNB or eNodeB), in a third Generation 3G network, the device is called a Node B (Node B), or the device is applied to a Next Generation Node B (Next Generation Node B, gnnodeb or gNB), an NR base station, or a gNB in a fifth Generation communication system, and may be other similar network devices.
In one embodiment, as shown in fig. 3, a method for optimizing communication of a terminal is provided, which is described by taking the method as an example applied to the terminal in fig. 1 or fig. 2, and the terminal is configured with an antenna for supporting wireless signal communication; the wireless signals comprise a first communication signal and a second communication signal; the method comprises the following steps:
step 302, sending sounding reference signals by multiple antennas in turn, and monitoring a signal indicator of the first communication signal.
The terminal is provided with an antenna for supporting wireless signal communication, and the number of the antennas can be multiple; the wireless signals may include a first communication signal and a second communication signal, that is, the wireless signals supported by the terminal may be classified into the first communication signal and the second communication signal; in some examples, the second communication signal and the first communication signal may be in an operational state at the same time (e.g., LTE/NR/GNSS/WIFI simultaneous operation); further, the first communication signal may refer to a target signal to be optimized, and the second communication signal may refer to a signal that may interfere with the target signal with respect to the target signal, that is, the second communication signal belongs to a part of wireless signals supported by the terminal, and the part of wireless signals may interfere with an operating performance of another part of wireless signals (the first communication signal) supported by the terminal when operating.
In one embodiment, the second communication signal comprises at least one of an LTE signal and an NR signal; the first communication signal includes at least one of a GNSS signal and a WIFI signal. It can be understood that, taking the terminal as a PC/CPE as an example, LTE/NR and GNSS/WIFI can simultaneously operate in a PC/CPE system, and a partial LTE/NR frequency band may have an influence on the receiving performance of the GNSS/WIFI, and further, in this embodiment of the present application, the first communication signal may refer to a GNSS/WIFI signal, and the second communication signal may refer to an LTE/NR signal.
Further, the multiple antennas configured for the terminal may be divided into a first antenna group and a second antenna group, and the first antenna group is independent from the second antenna group; each antenna in the first antenna group may be configured to support communication of a second communication signal and each antenna in the second antenna group may be configured to support communication of a first communication signal. Taking fig. 1 as an example, ANT0/1/2/3 may be used as each antenna in the first antenna set, and GNSS ANT and WIFI ANT may be used as each antenna in the second antenna set. In addition, each antenna in the first antenna group needs to be able to support the function of the sounding reference signal SRS, for example, the sounding reference signal SRS is transmitted as a transmission signal by different antennas (ANT 0/1/2/3).
Specifically, the application provides that the Sounding Reference Signal (SRS) is transmitted by a plurality of antennas in turn, and the signal index of the first communication signal is monitored. That is, in the present application, a terminal may send sounding reference signals SRS to a base station through multiple antennas in turn; in some examples, the terminal may sequentially transmit the sounding reference signal SRS to the base station through each of at least 4 antennas, that is, the terminal may transmit the sounding reference signal SRS to the base station in a manner of 1T 4R.
The terminal may monitor a signal indicator of the first communication signal when transmitting sounding reference signals on different antennas in turn. In one embodiment, the signal indicator is used to characterize the reception performance of the first communication signal; the signal index in this application may refer to an index used for characterizing reception performance of the first communication signal, and taking the first communication signal as a GNSS signal/WIFI signal as an example, the signal index may refer to an index received by a GNSS/WIFI IC (Integrated Circuit).
In one embodiment, the signal indicator comprises a signal-to-noise ratio;
the step of monitoring a signal indicator of a first communication signal by alternately transmitting sounding reference signals through a plurality of antennas includes:
the method comprises the steps of sequentially sending sounding reference signals through each antenna of at least 4 antennas, and obtaining the numerical value of the signal-to-noise ratio of a first communication signal when the sounding reference signals are sent each time.
Specifically, the signal index in the present application may refer to a signal-to-noise ratio SNR; taking the first communication signal as a GNSS signal/WIFI signal as an example, the signal-to-noise ratio SNR may be an index received by the GNSS/WIFI IC, and the larger the value of the signal-to-noise ratio SNR is, the better the receiving capability of the GNSS/WIFI is (the better the receiving performance is).
The method for transmitting the sounding reference signal SRS to the base station by using 1T4R is provided (that is, the terminal sequentially transmits the sounding reference signal through each of at least 4 antennas), and the value of the signal-to-noise ratio is obtained when the sounding reference signal is transmitted each time.
In one embodiment, the method may further include the steps of:
determining the sending time of each sending of the sounding reference signal according to a preset time interval; the preset time interval is obtained based on the calculation time of the signal-to-noise ratio.
Specifically, the transmission time of each transmission of the sounding reference signal in the present application may be modified, wherein the transmission time of the sounding reference signal may be set by software; furthermore, the sending time of the sounding reference signal can be determined according to a preset time interval, the preset time interval is obtained based on the calculation time of the signal-to-noise ratio, and the signal-to-noise ratio SNR calculation can be further guaranteed to be completed.
By taking the terminal to send the sounding reference signal SRS to the base station in a 1T4R manner, the first communication signal refers to a GNSS signal/WIFI signal, the second communication signal refers to an LTE signal/NR signal as an example, the terminal sends the sounding reference signal SRS through a plurality of antennas by adopting a 1T4R function, wherein the SRS/TX switching round sending time is short, the TX round sending time can be modified by the method, and the GNSS/WIFI can be guaranteed to complete the SNR calculation.
Step 304, determining the communication quality of the first communication signal at each transmission of the sounding reference signal according to the signal indicator.
Specifically, the communication quality achieved by the first communication signal can be determined every time the sounding reference signal is transmitted according to the signal index. The communication quality may refer to a reception performance of the first communication signal. Taking the first communication signal as a GNSS signal/WIFI signal and the signal index as a signal-to-noise ratio SNR as an example, the larger the monitored signal-to-noise ratio SNR is, the better the receiving capability of the GNSS/WIFI is (the better the receiving performance is).
Furthermore, when the sounding reference signal is transmitted by different antennas, the influence of the second communication signal on the first communication signal is minimum when the second communication signal is transmitted by which antenna according to the monitoring signal index.
In one embodiment, the step of determining, according to the signal indicator, the communication quality achieved by the first communication signal at each transmission of the sounding reference signal includes:
and under the condition of acquiring the signal-to-noise ratio with the maximum value, determining that the first communication signal achieves the best communication quality.
Specifically, according to the signal index, the method and the device can determine under which condition the first communication signal in work can reach the best communication quality. Taking the first communication signal as a GNSS signal/WIFI signal and the signal index as a signal-to-noise ratio SNR as an example, the performance index of the first communication signal may be optimal when determining which antenna transmits the second communication signal according to the value of the signal-to-noise ratio SNR, for example, when the value of the signal-to-noise ratio SNR is maximum, it may be determined that the first communication signal reaches the optimal receiving capability at this time.
In step 306, in the case that the first communication signal is confirmed to reach the best communication quality, the corresponding antenna is configured as an antenna for supporting communication of the second communication signal.
Specifically, in the process of transmitting the sounding reference signal by the terminal through the multiple antennas, the signal index of the first communication signal is acquired, and then the communication quality of the first communication signal achieved when the sounding reference signal is transmitted each time can be determined.
In one embodiment, the number of antennas used to support communication of the second communication signal is one.
Specifically, according to the present application, the number of antennas for supporting the second communication signal communication is determined to be one, and the antennas are used as fixed antennas for supporting the second communication signal communication, so that it can be ensured that the index of the first communication signal is better in the case where the second communication signal and the first communication signal operate simultaneously.
Taking as an example that the plurality of antennas configured by the terminal device can be classified into a first antenna group and a second antenna group for supporting communication of the first communication signal, the first antenna group may be independent of the second antenna group; based on the application, the antenna for supporting the second communication signal communication is one of the antennas for sending the sounding reference signal in turn, and the antennas for sending the sounding reference signal in turn are all antennas in the first antenna group.
In the terminal communication optimization method, when the sounding reference signal is transmitted by different antennas, the influence of the sounding reference signal on the first communication signal when the sounding reference signal is transmitted by which antenna is the smallest is judged by monitoring the signal index, so that the second communication signal is controlled to radiate communication on the antenna with smaller influence, and the communication performance of the first communication signal is better. The working antenna of the second communication signal is controlled, so that the second communication signal works on the antenna which is the most optimal antenna in the communication performance of the first communication signal in the terminal antenna, the signal index of the first communication signal is optimized, and the communication performance of the first communication signal is improved.
To further illustrate the solution of the present application, the following is described with reference to a specific example:
as shown in fig. 4, taking the terminal as a PC/CPE system as an example, the default LTE/NR TX operates on a fixed antenna, and LTE/NR and GNSS/WIFI operate simultaneously; wherein, LTE/NR supports 1T4R, and TX is transmitted on 4 antennas in turn, and then GNSS/WIFI monitors SNR index. Monitoring the change of the GNSS/WIFI SNR index, and judging that the SNR of the GNSS/WIFI is relatively optimal when the LTE/NR is transmitted by one antenna of ANT 0-3 (ANT0/1/2/3 in figure 1); and the emission of the LTE/NR is configured and fixed on an antenna with the optimal GNSS/WIFI SNR.
It should be noted that, at present, both LTE and NR products support 4MIMO function, while LTE/NR band of 5G (5th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology) can support 1T4R (1Transmit 4Radiation) function; in this regard, in the present application, LTE/NR serves as a second communication signal of the first communication signal (GNSS/WIFI), and the terminal is configured with a corresponding antenna (e.g., a first antenna group, a second antenna group), so that the present application may apply the function of 1T4R, and TX of LTE/NR may be transmitted on 4 antennas.
Further, LTE/NR and GNSS/WIFI operate simultaneously in a PC/CPE system, and a partial LTE/NR frequency band may affect the receiving performance of the GNSS/WIFI, and based on the present application, the LTE/NR is controlled to perform round-robin transmission among 4 antennas (transmission time may be configured by software, which ensures that the GNSS/WIFI can complete SNR calculation), and the GNSS/WIFI determines, according to the SNR size, which LTE/NR antenna transmits the highest SNR of the GNSS/WIFI (that is, by SNR index comparison, it is determined that the SNR performance of the GNSS/WIFI is optimal when the LTE/NR operates on which antenna), so as to control the TX of the LTE/NR to operate on the antenna (configure the LTE/NR transmits on the antenna); furthermore, the antenna which is relatively optimal for GNSS/WIFI SNR is controlled by TX of LTE/NR to work in ANT 0/1/2/3.
In addition, the SNR is the index of GNSS/WIFI IC receiving in the application, and the better the SNR is, the better the GNSS/WIFI receiving is. In the application, the LTE/NR antenna supports the SRS function, and the SRS function means that the transmission of LTE/NR can be transmitted on 4 antennas in turn; and when the LTE/NR is transmitted by different antennas, the GNSS/WIFI IC can monitor the SNR index, and then the influence on the GNSS/WIFI when the LTE/NR is transmitted by any antenna is judged to be minimum, so that the LTE/NR is controlled to be transmitted on the antenna with smaller influence, the GNSS/WIFI index is guaranteed to be more excellent, and the change of hardware is not needed.
In the above way, based on 1T4R (1Transmit 4Radiation) in LTE/NR 4MIMO and SRS/TX switching, LTE/NR transmits in different LTE/NR antennas, and an antenna with the optimal GNSS/WIFI SNR index is selected as an LTE/NR transmitting antenna by monitoring the SNR index of GNSS/WIFI, so that the SNR index of GNSS/WIFI is optimized, and the performance of GNSS/WIFI is improved.
