Detailed Description
The technical solution in the present application will be described below with reference to the accompanying drawings.
The embodiments of the present application may be applied to various communication systems, such as Wireless Local Area Network (WLAN), narrowband band-internet of things (NB-IoT), global system for mobile communications (GSM), enhanced data rate GSM evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), code division multiple access (code division multiple access, CDMA2000), time division synchronous code division multiple access (TD-SCDMA), long term evolution (long term evolution, LTE), satellite communication, fifth generation (5G), or new communication systems.
The terminal devices referred to in the embodiments of the present application may include various handheld devices, vehicle mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capability. The terminal may be a Mobile Station (MS), a subscriber unit (subscriber unit), a User Equipment (UE), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a Personal Digital Assistant (PDA) computer, a tablet computer, a wireless modem (modem), a handheld device (handset), a laptop computer (laptop computer), a Machine Type Communication (MTC) terminal, or the like.
In a wireless communication system, as a communication distance is reduced, a negotiation rate is increased, and a communication rate is increased. The closer the distance, the higher order modulated signal can carry more bits, i.e. carry more information, and the reliability of the communication can also be improved. However, the gain of the Power Amplifier (PA) is fixed, and under the high-order modulation technique, the linearity of the device is limited, and the transmission Power of the PA is low, which further limits the coverage of the high negotiation rate.
In many countries or regions there are strict radio radiated energy regulations governing the total value of the transmit power and antenna gain of a power amplifier. For example, the transmission power of the PA is high in the low rate mode, so that the gain value of the antenna is severely limited.
In some application scenarios, a single antenna with low gain is used. As shown in fig. 1, a diagram of the relationship between the transmission power at different rates and the difference between the regulatory limit minus the antenna gain value is shown. In the low-rate mode, the transmitting power of the PA is just equal to the difference value between the regulation limit and the antenna gain value of the single antenna; in medium and high rate modes, the transmit power of the PA is less than the regulatory limit for the difference in antenna gain values for the single antenna. Therefore, when a single antenna with low gain is used, the sum of the transmission power of the PA and the antenna gain value cannot reach the regulatory limit value in the medium-rate mode and the high-rate mode, and therefore, the transmission capability of the PA has room for improvement.
In other application scenarios, a single antenna of lower gain is used. As shown in fig. 2, another diagram of the relationship between the transmitted power at different rates and the difference between the regulatory limit minus the antenna gain value is shown. In the low rate mode, the transmit power of the PA exceeds the regulatory limit and the difference between the antenna gain value of the single antenna, and in one implementation, only the actual transmit power of the PA is limited, so the transmit power of the PA is wasted. In the medium-rate mode, the transmit power of the PA is just equal to the difference between the regulatory limit and the antenna gain value of the single antenna. In the high rate mode, the transmit power of the PA is less than the regulatory limit by the antenna gain value of the single antenna. Therefore, when a single antenna with lower gain is used, the sum of the transmission power of the PA and the antenna gain value cannot reach the regulatory limit value in the high-rate mode, and therefore, the transmission capability of the PA has room for improvement. In addition, in the low-rate mode, limiting the actual transmission power of the PA is costly and difficult.
To this end, the present embodiment provides a method 300 for determining a target transmitting antenna, where the method 300 can improve the performance of communication. As shown in fig. 3, a schematic flow chart of a method for determining a target transmitting antenna of the embodiment of the present application is shown.
The method 300 may be applied to a communication device 400 comprising a power amplifier and a transmit antenna, as shown in fig. 4, which shows a schematic block diagram of the communication device 400. The communication device 400 includes a signal transceiver 410, a power amplifier 420, a processor 430, and a transmit antenna 440; the signal transceiver is used for generating signals, the signals generated by the signal transceiver are transmitted to the power amplifier, the power amplifier amplifies the signals and transmits the power amplified signals to the processor, so that the processor selects the transmitting antenna and controls the transmitting antenna to transmit the signals.
The transmitting antenna 440 includes a first transmitting antenna 441 or a plurality of second transmitting antennas 442, where an antenna gain value of the first transmitting antenna is adjustable, and an antenna gain value of the second transmitting antenna is not adjustable, where antenna gain values of any two antennas of the plurality of second transmitting antennas are different. The method 300 includes:
the transmit power of the power amplifier is determined 310, which is related to the transmit power of the signal transceiver to which the power amplifier is connected and the gain of the power amplifier, which is generally constant and has a certain limit on its transmit capability.
320, determining a first antenna gain value according to the determined transmit power and a first threshold; optionally, the sum of the transmission power and the first antenna gain value may be equal to the first threshold, and the sum of the transmission power and the first antenna gain value may also be smaller than the first threshold.
Alternatively, the first threshold may be determined according to regulatory limits. Specifically, the first threshold may be a regulatory limit value, or may be smaller than the regulatory limit value, which may be determined according to an actual application scenario, and this is not limited in this application embodiment. It should be understood that, by confirming the regulatory limit of the country of sale of the communication device and subtracting the transmission power of the power amplifier from the regulatory limit, a maximum antenna gain value can be obtained, and the first antenna gain value can be equal to or smaller than the maximum antenna gain value.
For example, the communication device is sold to europe, and according to the european regulatory limit, the maximum limit of the Equivalent Isotropic Radiated Power (EIRP) is 30dBm, and it is assumed that the transmission Power of the Power amplifier in the low-rate mode is 22dBm, the transmission Power in the medium-rate mode is 20dBm, and the transmission Power in the high-rate mode is 18 dBm. Therefore, in the low-rate mode, the maximum antenna gain value of the transmitting antenna of the communication device is 30-22 ═ 8 dBi; in the medium-rate mode, the maximum antenna gain value of a transmitting antenna of the communication equipment is 30-20-10 dBi; in the high-rate mode, the maximum antenna gain value of the transmitting antenna of the communication device is 30-18 to 12 dBi.
Optionally, if the communication device uses a Multiple Input Multiple Output (MIMO) mode for communication, the first threshold is determined according to a regulatory limit and a first MIMO mode currently used by the communication device. Specifically, the first threshold is equal to or less than a regulatory limit minus a combining gain of the first MIMO mode. The maximum antenna gain value can be obtained by subtracting the transmitting power of the power amplifier from the regulatory limit value and then subtracting the combining gain of the first MIMO mode, and the first antenna gain value can be equal to or smaller than the maximum antenna gain value. It should be understood that the combining gain refers to a gain multiple of the multiple transmitting antennas, for example, 2 × 2MIMO mode, and the combining gain is 2 times, i.e., 3dBi, in the case of performing communication in the MIMO mode, using multiple transmitting antennas to transmit signals, each antenna having one antenna gain value.
For example, the product specification of the communication device is 4 × 4MIMO mode, in which the combining gain of the communication device is 6dB, the maximum EIRP limit is 30dBm according to european regulatory limits, and it is assumed that the transmission power of the power amplifier in the low-rate mode is 22dBm, the transmission power in the medium-rate mode is 20dBm, and the transmission power in the high-rate mode is 18 dBm. Therefore, in the low-rate mode, the maximum antenna gain value of the transmitting antenna of the communication device is 30-22-6 ═ 2 dBi; in the medium-rate mode, the maximum antenna gain value of the transmitting antenna of the communication equipment is 30-20-6-4 dBi; in the high rate mode, the maximum antenna gain value of the transmitting antenna of the communication device is 30-18-6 to 6 dBi.
If the communication device uses the first transmitting antenna with the adjustable antenna gain value, the antenna gain value of the first transmitting antenna is modulated to be the first antenna gain value, and the first transmitting antenna is determined to be the target transmitting antenna 330. In some possible implementations, the first transmitting antenna includes a plurality of gears, each gear representing an antenna gain value, and the antenna gain value can be made to be the first antenna gain value by modulating the gear of the first transmitting antenna; in this case, the antenna gain values represented by the plurality of gear positions of the first transmitting antenna and the first antenna gain value may not be completely matched, and the gear position of the first transmitting antenna may be modulated to a gear position at which the antenna gain value represented by the gear position is closest to the first antenna gain value. In other possible implementations, the antenna gain value of the first transmit antenna is continuously modulatable, i.e., can be modulated to an arbitrary value.
If the communication device uses the second transmitting antennas with different antenna gain values, one of the second transmitting antennas may be determined as a target transmitting antenna, and the antenna gain value of the target transmitting antenna is the first antenna gain value. Wherein the gain value of the second transmit antenna is fixed, non-adjustable. It should be understood that the first antenna gain value and the antenna gain values of the plurality of second transmitting antennas may not be able to be completely matched, in which case the second transmitting antenna with the antenna gain value closest to the first antenna gain value may be selected as the target transmitting antenna.
And finally, the target transmitting antenna sends signals.
In the technical scheme provided by the embodiment of the application, in a high-rate mode, the transmitting power of the power amplifier is low, the antenna gain value of the transmitting antenna can be increased, or the transmitting antenna with the large antenna gain value is selected to transmit signals, so that the signal-to-noise ratio of the signals received by the receiving end can be improved; in the low-rate mode, the transmitting power of the power amplifier is high, the antenna gain value of the transmitting antenna can be adjusted to be small, or the transmitting antenna with the small antenna gain value is selected to transmit signals, so that the signals can be covered more comprehensively, the energy of free space is dispersed more uniformly, and the communication performance can be improved.
Another method 500 for determining a target transmitting antenna is provided in the embodiments of the present application, and as shown in fig. 5, a schematic flow chart of another method 500 for determining a target transmitting antenna in the embodiments of the present application is shown.
The method 500 for determining a target transmitting antenna is applied to a communication device including a power amplifier and transmitting antennas, where the transmitting antennas include a first transmitting antenna and at least one second transmitting antenna, where an antenna gain value of the first transmitting antenna is adjustable, an antenna gain value of the second transmitting antenna is not adjustable, and when the number of the second transmitting antennas is at least two, antenna gain values of any two of the second transmitting antennas are different. That is, the communication apparatus includes not only the first transmission antenna whose antenna gain value is adjustable but also the second transmission antenna whose antenna gain value is not adjustable.
The transmit power of the power amplifier is determined 510, which is related to the transmit power of the signal transceiver to which the power amplifier is connected and the gain of the power amplifier, which is generally constant and has a certain limit on its transmit capability.
Determining 520 a first antenna gain value based on the determined transmit power and a first threshold; optionally, the sum of the transmission power and the first antenna gain value may be equal to the first threshold, and the sum of the transmission power and the first antenna gain value may also be smaller than the first threshold.
Alternatively, the first threshold may be determined according to regulatory limits. Specifically, the first threshold may be a regulatory limit value, or may be smaller than the regulatory limit value, which may be determined according to an actual application scenario, and this is not limited in this application embodiment. It should be understood that, by confirming the regulatory limit of the country of sale of the communication device and subtracting the transmission power of the power amplifier from the regulatory limit, a maximum antenna gain value can be obtained, and the first antenna gain value can be equal to or smaller than the maximum antenna gain value.
Optionally, if the communication device uses the MIMO mode for communication, the first threshold is determined according to a regulatory limit and a first MIMO mode currently used by the communication device. Specifically, the first threshold is equal to or less than a regulatory limit minus a combining gain of the first MIMO mode. The maximum antenna gain value can be obtained by subtracting the transmitting power of the power amplifier from the regulatory limit value and then subtracting the combining gain of the first MIMO mode, and the first antenna gain value can be equal to or smaller than the maximum antenna gain value.
And 530, modulating the antenna gain value of the first transmitting antenna into the determined first antenna gain value, wherein the first transmitting antenna is determined as a target transmitting antenna. In some possible implementations, the first transmitting antenna includes a plurality of gears, each gear representing an antenna gain value, and the antenna gain value can be made to be the first antenna gain value by modulating the gear of the first transmitting antenna; in this case, the antenna gain values represented by the plurality of gear positions of the first transmitting antenna and the first antenna gain value may not be completely matched, and the gear position of the first transmitting antenna may be modulated to a gear position at which the antenna gain value represented by the gear position is closest to the first antenna gain value. In other possible implementations, the antenna gain value of the first transmit antenna is continuously modulatable, i.e., can be modulated to an arbitrary value.
Or, one of the second transmitting antennas is determined as a target transmitting antenna, and the antenna gain value of the target transmitting antenna is the first antenna gain value. The gain value of the second transmit antenna is fixed, non-adjustable. It should be understood that the first antenna gain value and the antenna gain values of the plurality of second transmitting antennas may not be able to be completely matched, in which case the second transmitting antenna with the antenna gain value closest to the first antenna gain value may be selected as the target transmitting antenna.
Finally, the target transmit antenna sends the signal.
In the technical scheme provided by the embodiment of the application, in a high-rate mode, the transmitting power of the power amplifier is low, the antenna gain value of the transmitting antenna can be increased, or the transmitting antenna with the large antenna gain value is selected to transmit signals, so that the signal-to-noise ratio of the signals received by the receiving end can be improved; in the low-rate mode, the transmitting power of the power amplifier is high, the antenna gain value of the transmitting antenna can be adjusted to be small, or the transmitting antenna with the small antenna gain value is selected to transmit signals, so that the signals can be covered more comprehensively, the energy of free space is dispersed more uniformly, and the communication performance can be improved.
