Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal sending method and communication equipment. Background Art

[0002] Base stations often reduce transmitter power consumption by improving the efficiency of power amplifiers (PAs). One current approach to improving PA efficiency is to have multiple main PAs and a peak PA collaborate to transmit the signal corresponding to a data stream. Specifically, when the input signal's amplitude is less than or equal to a threshold, each of the multiple main PAs amplifies the input signal, while the peak PA is disconnected. When the input signal's amplitude is greater than the threshold, each of the multiple main PAs amplifies the portion of the input signal with an amplitude less than or equal to the threshold, while the peak PA amplifies the portion of the input signal with an amplitude greater than the threshold.

[0003] To ensure signal quality, the power of the PA's input signal cannot exceed the PA's maximum allowable input power. The input signal's peak-to-average ratio (PAPR) is the ratio of the input signal's peak power to its average power. This means that the lower the PA's input signal's PAPR, the greater the average power of the input signal it supports, and accordingly, the greater the PA's efficiency. Therefore, compared to multiple main PAs amplifying input signals with amplitudes greater than a threshold, multiple main PAs amplify the portion of the input signal with amplitudes less than or equal to the threshold, reducing the PA's input signal's peak-to-average ratio. This increases the average power of the signal supported by each main PA, thereby improving the efficiency of the multiple main PAs.

[0004] However, this approach only works for sending a single data stream, while base stations typically need to send multiple data streams for multiple users. Therefore, while reducing transmitter power consumption by improving PA efficiency, the technical challenge remains how to achieve low-complexity transmission of multiple data streams for multiple users. Summary of the Invention

[0005] The embodiments of the present application provide a signal transmission method and a communication device for transmitting multiple data streams for multiple users through a small number of PAs. The communication device has a simple structure and can reduce power consumption of the communication device.

[0006] In a first aspect, the present application provides a communication device comprising a baseband module, a first module, N first power amplifiers (PAs), and H second PAs, wherein the baseband module is connected to the first module, and the first module is connected to the N first PAs and the H second PAs. The functions of the modules included in the communication device are as follows:

[0007] a baseband module, configured to obtain N first signals based on M data streams of multiple users, wherein one first signal corresponds to at least two data streams of the M data streams, one data stream corresponds to at least two first signals of the N first signals, the N first signals correspond one-to-one to N first PAs, and amplitude values ​​of Q first signals of the N first signals are greater than a first threshold;

[0008] A first module is configured to determine a correspondence between Q first PAs corresponding to the Q first signals and Q second PAs among the H second PAs;

[0009] N first PAs, configured to amplify Q second signals and (NQ) first signals, wherein amplitudes of the (NQ) first signals are less than or equal to a first threshold;

[0010] Q second PAs are used to amplify Q third signals, wherein the third signal corresponding to the j-th second PA among the Q second PAs and the second signal corresponding to the ith first PA are used to synthesize the k-th first signal among the Q first signals, and there is a corresponding relationship between the ith first PA and the j-th second PA.

[0011] Wherein, N is an integer greater than 1. M is an integer greater than 1. H is an integer greater than 0 and less than N. Q is an integer greater than 0 and less than or equal to H.

[0012] Optionally, the amplified Q second signals and the amplified Q third signals can be synthesized in the spatial domain to obtain the amplified Q first signals, which can reduce the signal loss caused by the synthesis of the amplified Q second signals and the amplified Q third signals in the circuit.

[0013] In the above embodiment, the number of first PAs included in the communication device is greater than the number of second PAs. The first module can flexibly match the Q first PAs with the Q second PAs one-to-one by determining the correspondence between the Q first PAs and the Q second PAs among the H second PAs. A corresponding group of first PAs and second PAs collaboratively amplifies one of the Q first signals. This can improve the efficiency of the Q first PAs, reduce the power consumption of the communication device, reduce the number of PAs included in the communication device, and simplify the structure of the communication device.

[0014] In one possible design, the second signal corresponding to the i-th first PA is the part of the k-th first signal whose amplitude value is less than or equal to the second threshold; the third signal corresponding to the j-th second PA is the part of the k-th first signal whose amplitude value is greater than the second threshold.

[0015] With the above design, when the first and second PAs collaborate to amplify the first signal, the first PA amplifies the second signal, which is the portion of the first signal whose amplitude is less than or equal to the second threshold, and the second PA amplifies the remaining portion of the first signal. The amplitude of the second signal is smaller than the amplitude of the first signal, and the corresponding peak-to-average ratio of the second signal is smaller than that of the first signal. Therefore, compared to the first PA amplifying the first signal whose amplitude is greater than the first threshold, the first PA amplifying the second signal can increase the average power of the input signal supported by the first PA, improve the efficiency of the first PA, and thus reduce the power consumption of the communication device.

[0016] In one possible design, the first module is further used to adjust the first threshold to obtain the second threshold based on the multiple antenna elements connected to the i-th first PA and the multiple antenna elements connected to the j-th second PA, the state of the i-th first PA and the state of the j-th second PA.

[0017] Through the above design, the first module can adaptively adjust the first threshold according to the actual situation of the first PA and the second PA corresponding to the first PA to obtain the second threshold, so that the second signal and the third signal truncated by the second threshold are more consistent with the actual situation of the first PA and the second PA.

[0018] In one possible design, the first module is further configured to: determine Q compensation values ​​for Q third signals, where the Q third signals correspond one-to-one to the Q compensation values, and each compensation value includes at least one of a phase compensation value and an amplitude compensation value; and compensate the Q third signals based on the Q compensation values. For example, when determining the Q compensation values ​​for the Q third signals, the first module may be configured to determine the Q compensation values ​​based on at least one of location information of multiple users, channel information corresponding to the Q first PAs, and channel information corresponding to the Q second PAs. For example, the first module may also be configured to obtain location information of the multiple users based on channel information between the communication device and the multiple users.

[0019] Through the above design, the first module performs phase compensation, or amplitude compensation, or phase and amplitude compensation on the third signal. The compensated third signal can reduce the difference between the second signal corresponding to the third signal, and can improve the quality of the signal after the third signal and the second signal corresponding to the third signal are synthesized in the spatial domain.

[0020] In one possible design, the first module is further used to: obtain Q second signals and Q third signals from the Q first signals; send the Q second signals to the Q first PAs; and send the Q third signals to the Q second PAs.

[0021] Through the above design, the communication device can cut the first signal into the second signal and the third signal by software, without cutting it by hardware, thereby simplifying the structure of the communication device.

[0022] In one possible design, the amplitude value of the kth first signal is greater than the first threshold in the first time period, and the amplitude value is less than or equal to the first threshold in the second time period. The first module is used to: obtain a second signal and a third signal from the kth first signal in the first time period, send a second signal to the i-th first PA, and send a third signal to the j-th second PA; and send the kth first signal to the i-th first PA in the second time period.

[0023] With this design, the first module can perform different processing on the first signal in different time periods. For example, during a first time period when the amplitude of the first signal is greater than a first threshold, the first module extracts the second and third signals from the first signal and sends the second signal to the first PA and the third signal to the second PA. During a second time period when the amplitude of the first signal is less than the first threshold, the first module sends the first signal to the first PA. This approach enables flexible scheduling of H second PAs, meeting the need for Q first PAs to collaborate with Q second PAs at any given time.

[0024] In one possible design, the communication device further includes a first antenna module and a second antenna module, a first PA is connected to multiple antenna elements in the first antenna module, and a second PA is connected to multiple antenna elements in the second antenna module.

[0025] Through the above design, one PA is connected to multiple antenna elements, and signals can be sent through the multiple antenna elements, which can improve signal gain.

[0026] In one possible design, the Q first PAs may also be used to transmit the amplified Q second signals;

[0027] The remaining (NQ) first PAs may also be used to send the amplified (NQ) first signals;

[0028] The Q second PAs may also be used to send the amplified Q third signals.

[0029] Through the above design, Q first PAs amplify Q second PAs and send the amplified Q second PAs, the remaining (NQ) first PAs amplify (NQ) first signals and send the amplified (NQ) first signals, and Q second PAs amplify Q third signals and send the amplified Q third signals, thereby enabling the transmission of multiple data streams to multiple users through a small number of PAs.

[0030] In a second aspect, the present application provides a communication device comprising: a baseband module, N first power amplifiers (PAs), and N second PAs, wherein the baseband module is connected to the N first PAs and the N second PAs, and the N first PAs correspond one-to-one with the N second PAs.

[0032] Q first PAs corresponding to the Q first signals are used to amplify the Q second signals;

[0033] Q second PAs corresponding to Q first PAs are used to amplify Q third signals, wherein the third signal corresponding to the j-th second PA among the Q second PAs and the second signal corresponding to the ith first PA are used to synthesize the k-th first signal among the Q first signals, and the ith first PA corresponds to the j-th second PA.

[0034] Optionally, the amplified Q second signals and the amplified Q third signals can be synthesized in the spatial domain to obtain the amplified Q first signals, which can reduce the signal loss caused by the synthesis of the amplified Q second signals and the amplified Q third signals in the circuit.

[0035] Wherein, N is an integer greater than 1. M is an integer greater than 1. Q is an integer greater than 0 and less than or equal to N.

[0036] In the above embodiment, the communication device includes a baseband module, N first PAs, and N second PAs, with one first PA corresponding to one second PA. The baseband module can obtain N first signals from multiple data streams from multiple users, where Q of the N first signals have a peak-to-average ratio greater than a first threshold. The Q first PAs and Q second PAs, which have a one-to-one correspondence, can collaboratively transmit the Q first signals. This improves the efficiency of the Q first PAs and reduces the power consumption of the communication device. This enables transmission of multiple data streams from multiple users using a small number of PAs, simplifies the structure of the communication device, and facilitates implementation.

[0037] In one possible design, the second signal corresponding to the i-th first PA is the part of the k-th first signal whose amplitude value is less than or equal to the second threshold; the third signal corresponding to the j-th second PA is the part of the k-th first signal whose amplitude value is greater than the second threshold.

For example, when determining the Q compensation values ​​for the Q third signals, the first module is specifically configured to determine the Q compensation values ​​based on at least one of location information of multiple users, channel information corresponding to the Q first PAs, and channel information corresponding to the Q second PAs. For example, the first module is further configured to: obtain location information of the multiple users based on channel information between the communication device and the multiple users.

[0044] Through the above design, the communication device can cut the first signal into the second signal by hardware, and send the second signal to the first PA, so as to improve the efficiency of the first PA.

[0045] In one possible design, the Q second PAs are further used to obtain Q third signals from the Q first signals.

[0085] The embodiments of the present application provide a signal transmission method and a communication device for transmitting multiple data streams of multiple users through a small number of PAs. This method can reduce the power consumption of the communication device by improving the efficiency of the PA, simplify the structure of the communication device, and facilitate implementation.

[0086] The signal transmission method provided in this application can be applied to a 5G new radio (NR) system, or can also be applied to other communication systems, for example, an Internet of Things (IoT) system, a V2X system, a narrowband Internet of Things (NB-IoT) system, an LTE system, a fifth generation (5G) communication system, a hybrid architecture of LTE and 5G, an NR system, and new communication systems that will emerge in future communication developments.

[0087] It is worth noting that the communication device involved in the embodiments of the present application may be an electronic device with a transmitting function, or may be an electronic device with a transmitting function and a receiving function, and the specific implementation form of the communication device in the embodiments of the present application is not limited thereto. For example, the communication device may be a transmitter.

[0088] The following describes an embodiment of the present application by taking a communication device as a transmitter as an example.

[0089] Figure 1 A schematic diagram of a transmitter provided in an embodiment of the present application is shown.

[0090] like Figure 1 As shown, the transmitter 100 includes a baseband module 101, a first module 102, N first PAs and H first PAs. Figure 1 For example, N first PAs are recorded as PA 1_1, PA 1_2, ..., PA 1_N, and H second PAs are recorded as PA 2_1, PA 2_2, ..., PA2_H. Where N is an integer greater than 1. H is an integer greater than 0 and less than N. The baseband module 101 is connected to the first module 102, and the first module 102 is connected to the N first PAs and the H second PAs. In addition, Figure 1 This is merely an example and does not limit the order of the N first PAs and the H second PAs. For example, the N first PAs and the H second PAs can be arranged alternately. Furthermore, the present embodiment does not limit the types of the first PAs and the second PAs. Furthermore, the baseband module 101 may also be referred to as a second module or a signal acquisition module, etc., which is not limited in the present embodiment.

[0091] The number of first PAs included in transmitter 100, that is, the value of N, can be determined according to the number of transmit channels supported by transmitter 100. For example, the value of N is equal to the number of transmit channels supported by transmitter 100. For example, if transmitter 100 includes 64 transmit channels, the value of N can be 64. For another example, if transmitter 100 includes 32 transmit channels, the value of N can be 32.

[0092] The number of second PAs included in the transmitter 100, that is, the value of H, can be determined based on the first threshold and a preset error probability. For example, the value of H can be determined by simulation data, the first threshold, and a preset error probability. The first threshold can be pre-set or determined based on the performance curves of N first PAs, etc., and the embodiments of the present application are not limited to this. In the embodiments of the present application, if the amplitude value of the input signal is greater than the first threshold, then when the first PA amplifies the input signal, the efficiency of the first PA is less than or equal to the efficiency of the first PA at full power. The first threshold can also be called a truncation threshold or a clipping threshold, etc. The simulation data is obtained through simulation, and the value of H under different first thresholds and different error probabilities can be determined.

[0093] The preset error probability can be understood as the error probability that, among the N input signals corresponding to the N first PAs acceptable to transmitter 100, H input signals simultaneously have amplitudes greater than a first threshold. For example, if the error probability acceptable to transmitter 100 is the first probability, this means that, among the N input signals, the probability that N1 input signals simultaneously have amplitudes greater than the first threshold is less than or equal to the first probability. N1 is an integer greater than H and less than or equal to N.

[0094] For example, Table 1 shows a schematic diagram of simulation data. As shown in Table 1, if the first threshold is 2 decibels (dB) and the preset error probability is 0.001, the value of H is n1; if the first threshold is 2dB and the preset error probability is 0.0001, the value of H is n2; if the first threshold is 3dB and the preset error probability is 0.0001, the value of H is n1; if the first threshold is 4dB and the preset error probability is 0.0001, the value of H is n3. It can be understood that the various data shown in Table 1 are all examples, and the embodiments of the present application are not limited thereto. In addition, the embodiment of the present application is not limited to this in terms of the form of expression of simulation data. For example, the simulation data can be a curve. In this case, H can be the minimum integer that satisfies the curve, such as Figure 2 shown.

[0095] Table 1

[0096] First threshold Error probability The value of H 2dB 0.001 n1 2dB 0.0001 n2 3dB 0.0001 n1 4dB 0.0001 n3

[0097] In the above method, the value of H is obtained through the actual needs of the transmitter 100 and simulation data, so that the number of input signals that are simultaneously greater than the first threshold among the N input signals of the N first PAs is less than or equal to H. That is, the H second PAs can meet the needs of the N first PAs for collaborative amplification of the input signals, thereby using a small number of second PAs to improve the efficiency of the N first PAs and reduce the power consumption of the transmitter.

[0098] It should be noted that the baseband module 101 and the first module 102 in the embodiment of the present application can be integrated on a single chip, such as a radio on chip (ROC), or can be integrated on different chips. The present application does not limit the specific implementation of the baseband module 101 and the first module 102. In addition, in one possible implementation, the baseband module 101 may include the first module 102, that is, the baseband module 101 can implement the functions implemented by the first module 102. When the baseband module 101 includes the first module 102, the baseband module 101 is connected to N first PAs and H second PAs. The following description takes the case where the baseband module 101 does not include the first module 102 as an example.

[0099] Next, the functions of the baseband module 101, the first module 102, the N first PAs, and the H second PAs are introduced.

[0100] The baseband module 101 can be configured to obtain N first signals based on M data streams from multiple users. For example, the baseband module 101 can obtain N first signals based on the number of transmit channels supported by the transmitter 100 and the M data streams. For example, if the transmitter 100 supports 64 transmit channels, with each transmit channel corresponding to a first PA, the baseband module 101 can process the M data streams to obtain a 64-row, 64-column data matrix. Each row of data in the data matrix corresponds to a first signal, thereby obtaining 64 first signals. For example, the baseband module 101 can perform weighted processing on the M data streams based on the channel matrices of the multiple users to obtain the 64-row, 64-column data matrix. Each row of data in the data matrix is ​​different, and accordingly, each row of data in the data matrix corresponds to a different first signal, such as a different signal amplitude. Furthermore, a single user can correspond to one or more of the M data streams. M is an integer greater than 1.

[0101] For ease of description, in the embodiment of the present application, the N first signals are denoted as S1, S2, ..., SN. The N first signals correspond one-to-one to the N first PAs, such as signal S1 corresponds to PA 1_1, and signal S2 corresponds to PA 1_2. One first signal can correspond to two or more data streams among the M data streams. One data stream can correspond to two or more first signals among the N first signals. For example, signal S1 is a weighted signal of data stream A and data stream B, and signal S2 is another weighted information of data stream A and data stream B. The user can obtain data stream A and data stream B from signal S1 and signal S2. Wherein, M is an integer greater than 1.

[0102] Optionally, the baseband module 101 may also send N first signals to the first module 102; correspondingly, the first module receives the N first signals.

[0103] In an embodiment of the present application, the amplitude values ​​of Q first signals among the N first signals are greater than a first threshold, and the amplitude values ​​of the remaining (NQ) first signals are less than or equal to the first threshold. Q is an integer greater than 1 and less than or equal to H.

[0104] The first module 102 can be used to determine the correspondence between the Q first PAs corresponding to the Q first signals and the Q second PAs among the H second PAs. The correspondence between the Q first PAs and the Q second PAs can be understood as which second PA among the Q second PAs corresponds to one of the Q first PAs. Specifically, the first module 102 can determine Q first signals with amplitude values ​​greater than a first threshold from the N first signals, select Q second PAs from the H second PAs, and determine the correspondence between the Q second PAs and the Q first PAs corresponding to the Q first signals. That is, the first module 102 establishes a one-to-one correspondence between the selected Q second PAs and the Q first PAs. A group of first PAs and second PAs with this correspondence can be used to collaboratively amplify the first signal corresponding to the first PA, for example, the first PA is used to amplify the portion of the first signal with an amplitude value less than or equal to the second threshold, and the second PA is used to amplify the remaining portion of the first signal. In this way, the first module 102 can flexibly select Q second PAs from the H second PAs to correspond one-to-one with the Q first PAs, and cooperate to complete the transmission of the Q first signals, thereby reducing the number of PAs included in the transmitter 100.

[0105] For example, two first signals (e.g., signal S1 and signal S2) among N first signals have amplitudes greater than a first threshold. The two first PAs corresponding to these two first signals are PA 1_1 and PA 1_2, respectively. The first module 102 selects two second PAs (e.g., PA 2_1 and PA 2_2) from the H second PAs and determines the corresponding relationship between PA 2_1 and PA 2_2 and PA 1_1 and PA 1_2. For example, PA 2_1 corresponds to PA 1_1, and accordingly, PA 2_1 and PA 1_1 collaborate to transmit signal S1. PA 2_2 corresponds to PA 1_2, and accordingly, PA 2_1 and PA 1_1 collaborate to transmit signal S2.

[0106] As an example, the first module 102 can also be used to obtain Q second signals and Q third signals from Q first signals. For example, the first module 102 obtains a second signal and a third signal from each of the Q first signals, resulting in Q second signals and Q third signals. A first signal with an amplitude greater than a first threshold can be truncated into a second signal and a third signal. Taking the kth first signal among the Q first signals as an example, the portion of the kth first signal with an amplitude less than or equal to the second threshold is a second signal, and the portion of the kth first signal with an amplitude greater than the second threshold is a third signal. Because the amplitude of the second signal is less than or equal to the second threshold, the peak-to-average ratio of the second signal is lower than that of the first signal. In this case, compared to the case where the first PA amplifies a first signal with an amplitude greater than the first threshold, the power backoff value corresponding to the first PA amplifying the second signal is reduced. That is, the average power of the signal supported by the first PA is increased, thereby improving the efficiency of the first PA.

[0107] Furthermore, the first module 102 is further configured to send the Q second signals to the Q first PAs corresponding to the Q first signals, and send the Q third signals to the Q second PAs.

[0108] The second threshold value may be the same as or different from the first threshold value, and this is not limited in this embodiment of the present application. The Q first PAs may correspond one-to-one with Q second threshold values, and the Q second threshold values ​​may be the same as or different, and this is not limited in this embodiment of the present application.

[0109] As an example, the first module 102 can also be used to adjust the first threshold to obtain Q second thresholds corresponding to the Q first PAs. The Q second thresholds correspond one-to-one to the Q first PAs. For example, the first module 102 can adjust the first threshold to obtain the Q second thresholds based on one or more of the following: the multiple antenna elements connected to the Q first PAs, the multiple antenna elements connected to the Q second PAs, the states of the Q first PAs (e.g., whether the first PAs are in a full power state), and the states of the Q second PAs (e.g., whether the second PAs are in a full power state). For example, if the i-th first PA among the Q first PAs has a corresponding relationship with the j-th second PA, the first module 102 can adjust the first threshold to obtain the second threshold corresponding to the i-th first PA based on one or more of the following: the positional relationship between the multiple antenna elements connected to the i-th first PA and the multiple antenna elements connected to the j-th second PA, the state of the i-th first PA, and the state of the j-th second PA.

[0110] Through the above example, the first module 102 can adaptively adjust the first threshold according to the actual conditions of the first PA and the second PA to obtain the second threshold that conforms to the actual conditions of the first PA and the second PA, thereby reducing the problem of decreased efficiency of the first PA caused by the amplitude value of the second signal exceeding the amplitude value of the first PA operating at full power.

[0111] It is worth noting that the amplitude value of the first signal may be variable, so the first module 102 needs to perform different processing on the first signal in different time periods. For example, the kth first signal among Q first signals, the kth first signal corresponds to the ith first PA, and the ith first PA corresponds to the jth second PA. The amplitude value of the kth first signal in the first time period is greater than the first threshold value, while the amplitude value of the kth first signal in the second time period is less than or equal to the first threshold value. Figure 3 As shown. Accordingly, during a first time period, the first module 102 can be configured to obtain a second signal and a third signal from the kth first signal, and transmit the second signal to the ith first PA and the third signal to the jth second PA. The second signal and the third signal are used to synthesize the kth first signal. During a second time period, the first module 102 is configured to transmit the kth first signal to the ith first PA. This approach enables flexible scheduling of H second PAs, meeting the need for Q first PAs to collaborate with Q second PAs at any given time.

[0112] It is understandable that the second threshold corresponding to a first PA at different times may be the same or different, and this embodiment of the application does not limit this. In addition, the first threshold may be variable or constant, and this embodiment of the application does not limit this.

[0113] In one possible implementation, the first module 102 may also be configured to determine Q compensation values ​​for the Q third signals and compensate the Q third signals based on the Q compensation values. The Q third signals correspond one-to-one to the Q compensation values. One of the Q compensation values ​​may include a phase compensation value, an amplitude compensation value, or both a phase compensation value and an amplitude compensation value. For example, the first module 102 may be configured to determine the Q compensation values ​​based on one or more of the location information of multiple users, the channel information corresponding to the Q first PAs, or the channel information corresponding to the Q second PAs. For example, the first module 102 may obtain the location information of the multiple users based on the channel information between the transmitter 100 and the multiple users.

[0114] Taking the example where the kth first signal corresponds to the ith first PA, and the first module 102 obtains the kth second signal and the kth third signal from the kth first signal, the first module 102 can determine one or more users corresponding to the multiple data streams based on the multiple data streams corresponding to the kth first signal; obtain the location information of the one or more users based on the historical channel information between the transmitter 100 and the one or more users; and then obtain the compensation value corresponding to the kth third signal based on one or more of the location information of the one or more users, the historical channel information corresponding to the Q first PAs, or the historical channel information corresponding to the Q second PAs, and compensate the kth third signal based on the compensation value.

[0115] The channel information may include at least one of the amplitude change and phase change of the signal corresponding to the transmit channel at each device in the transmit channel; or at least one of the total amplitude change and total phase change of the signal corresponding to the transmit channel. The channel information may also include at least one of the amplitude change and phase change of the signal from each transmit channel to each receive channel of the user.

[0116] Through the above implementation method, the first module 102 can perform phase compensation, amplitude compensation, or phase compensation and amplitude compensation on the third signal according to the actual situation of the channel corresponding to the third signal, which can reduce the difference between the compensated third signal and the second signal corresponding to the third signal, thereby improving the quality of the third signal and the second signal corresponding to the third signal after spatial domain synthesis.

[0117] In the above implementation, the transmitter 100 compensates the Q third signals by software. In another possible implementation, the transmitter 100 may perform phase compensation, amplitude compensation, or both phase compensation and amplitude compensation on the Q third signals by hardware. For example, the transmitter 100 may include N compensators, one of which is connected to a second PA ( Figure 1 (not shown). The Q compensators connected to the Q second PAs can be used to perform phase compensation, amplitude compensation, or phase and amplitude compensation on the Q third signals. The remaining (NQ) compensators are inoperative. Through the above implementation, the transmitter 100 can perform phase and / or amplitude compensation on the Q third signals through hardware, thereby reducing the difference between the compensated Q third signals and the Q second signals, thereby improving the quality of the signal after the Q third signals and the Q second signals are synthesized in the spatial domain.

[0118] The functions of baseband module 101 and first module 102 have been described above. Next, the functions of the N first PAs and H second PAs will be described. The N first PAs can be divided into Q first PAs corresponding to the Q first signals, and the remaining (NQ) first PAs. If Q is less than H, the H second PAs can be divided into Q second PAs corresponding to the Q first PAs, and the remaining (HQ) second PAs.

[0119] The Q first PAs may be used to amplify the Q second signals and transmit the amplified Q second signals. The remaining (NQ) first PAs may be used to amplify (NQ) first signals having amplitudes less than or equal to a first threshold and transmit the amplified (NQ) first signals.

[0120] The Q second PAs can be used to amplify the Q third signals and transmit the amplified Q third signals. If Q is less than H, the remaining (HQ) second PAs have no signal input and are disconnected or inoperative.

[0121] In an embodiment of the present application, the amplified Q second signals and the amplified Q third signals can be synthesized in the spatial domain to obtain the amplified Q first signals, which can reduce the signal loss caused by the synthesis of the amplified Q second signals and the amplified Q third signals in the circuit.

[0122] In a possible implementation, the transmitter 100 may further include a first antenna module and a second antenna module, wherein a first PA is connected to multiple antenna elements in the first antenna module, and a second PA is connected to multiple antenna elements in the second antenna module. Figure 1Take a first PA connected to two antenna elements in a first antenna module and a second PA connected to two antenna elements in a second antenna module as an example. Furthermore, Q first PAs can send amplified Q second signals through the multiple antenna elements connected to the Q first PAs. Q second PAs can send amplified Q third signals through the multiple antenna elements connected to the Q second PAs. And, the remaining (NQ) first PAs can send amplified (NQ) first signals through the multiple antenna elements connected to the (NQ) first PAs. Through this implementation method, one PA is connected to multiple antenna elements, and the PA can send signals through multiple antenna elements, which can increase signal gain.

[0123] Figure 4 Taking the amplitude values ​​of the signal S2 and the signal SN as an example, which are greater than the first threshold, the transmitter 100 is shown as a schematic diagram of sending N first signals. Figure 4 As shown, the first module 102 selects two second PAs from the H second PAs, namely PA 2_1 and PA 2_2, and determines that PA 1_2 corresponding to signal S2 corresponds to PA 2_2 among the H second PAs, and that PA1_N corresponding to signal SN corresponds to PA 2_1 among the H second PAs. The first module 102 obtains signals S2_1 and S2_2 from signal S2, and obtains signals SN_1 and SN_2 from SN. Signal S2_1 is the portion of signal S2 with an amplitude less than or equal to the second threshold corresponding to PA 1_2, signal S2_2 is the remaining portion of signal S2 excluding signal S2_1, signal SN_1 is the portion of signal SN with an amplitude less than or equal to the second threshold corresponding to PA 1_N, and signal SN_2 is the remaining portion of signal SN excluding signal SN_1. Further, PA 1_2 amplifies signal S2_1 and sends the amplified signal S2_1; PA1_2 amplifies signal S2_1 and sends the amplified signal S2_1; PA2_2 amplifies signal S2_2 and sends the amplified signal S2_2; PA 2_1 amplifies signal SN_2 and sends the amplified signal SN_2, as shown in FIG. Figure 4 As shown. The remaining (N-2) first PAs amplify the (N-2) first signals and transmit the amplified (N-2) first signals. The remaining (N-2) second PAs have no signal input and do not operate. The amplified signal S2_1 and the amplified signal S2_2 are spatially combined to obtain the amplified signal S2. The amplified signal SN_1 and the amplified signal SN_2 are spatially combined to obtain the amplified signal SN.

[0124] In the above embodiment, the number of first PAs included in the transmitter is greater than the number of second PAs. By determining the correspondence between the Q first PAs and the Q second PAs among the H second PAs, the first module can flexibly associate the Q first PAs with the Q second PAs one-to-one. The corresponding group of first PAs and second PAs collaboratively amplifies one of the Q first signals. This improves the efficiency of the Q first PAs, reduces the power consumption of the transmitter, and reduces the number of PAs included in the transmitter, simplifying the transmitter structure. Furthermore, the Q first PAs amplify the Q second PAs and transmit the amplified Q second PAs. The remaining (NQ) first PAs amplify the (NQ) first signals and transmit the amplified (NQ) first signals. The Q second PAs amplify the Q third signals and transmit the amplified Q third signals. This enables the transmission of multiple data streams to multiple users using a small number of PAs.

[0125] Figure 1 The number of second PAs in the illustrated transmitter 100 is less than the number of first PAs. Next, another transmitter 500 provided in an embodiment of the present application is introduced. The number of second PAs in the transmitter 500 is equal to the number of first PAs.

[0126] like Figure 5 As shown, the transmitter 500 includes a baseband module 501, N first PAs and N second PAs, Figure 5 In the example, N first PAs are recorded as PA 1_1, PA 1_2, ..., PA 1_N, and N second PAs are recorded as PA 2_1, PA 2_2, ..., PA 2_N, where N is an integer greater than 1. The baseband module 501 is connected to the N first PAs and the N second PAs.

[0127] In this embodiment of the present application, the number of first PAs and second PAs in transmitter 500 is equal, and there is a one-to-one correspondence between N first PAs and N second PAs. For example, PA 1_1 corresponds to PA 2_1, and PA 1_2 corresponds to PA 2_2. A corresponding set of first and second PAs can be used to collaboratively amplify an input signal. For example, the first PA amplifies the portion of the input signal with an amplitude less than or equal to a second threshold, while the second PA amplifies the remaining portion of the input signal. The determination of the number of first PAs can be referred to the relevant description of transmitter 100, and will not be repeated here. Furthermore, this embodiment of the present application does not limit the types of the first and second PAs.

[0128] The baseband module 501 can be configured to obtain N first signals based on M data streams from multiple users. These N first signals are different. For example, the baseband module 501 can obtain the N first signals based on the number of transmission channels supported by the transmitter 500 and the M data streams. A single user can correspond to one or more of the M data streams. The specific implementation process for the baseband module 501 obtaining the N first signals can be found in the aforementioned description of the baseband module 101 obtaining the N first signals and will not be further elaborated here.

[0129] For ease of description, in this embodiment of the present application, the N first signals are denoted as S1, S2, ..., SN. These N first signals correspond one-to-one to the N first PAs, for example, signal S1 corresponds to PA 1_1, and signal S2 corresponds to PA 1_2. One first signal can correspond to two or more of the M data streams. One data stream can correspond to two or more of the N first signals.

[0130] In an embodiment of the present application, the amplitude values ​​of Q first signals among the N first signals are greater than a first threshold. Q is an integer greater than 1 and less than or equal to N. When Q is less than N, the amplitude values ​​of the remaining (NQ) first signals among the N first signals excluding the Q first signals are less than or equal to the first threshold. The first threshold may be pre-set or determined based on performance curves of the N first PAs, and the embodiment of the present application is not limited thereto.

[0131] The Q first PAs corresponding to the Q first signals can be used to amplify Q second signals and transmit the amplified Q second signals. The Q second signals correspond to the Q first signals. A second signal is a portion of the first signal corresponding to the second signal whose amplitude is less than or equal to a second threshold. Taking the kth first signal among the Q first signals as an example, the portion of the kth first signal whose amplitude is less than or equal to the second threshold is a second signal.

[0132] Exemplarily, if Q is less than N, the remaining (NQ) first PAs may be used to amplify (NQ) first signals and transmit the amplified (NQ) first signals, wherein the amplitudes of the (NQ) first signals are less than or equal to the first threshold.

[0133] The Q second PAs corresponding to the Q first PAs can be used to amplify Q third signals and transmit the amplified Q third signals. The Q third signals correspond to the Q first signals. A third signal is a portion of the first signal corresponding to the third signal whose amplitude exceeds a second threshold. Taking the kth first signal among the Q first signals as an example, the portion of the kth first signal whose amplitude exceeds the second threshold is a second signal.

[0134] Exemplarily, if Q is less than N, the remaining (NQ) second PAs are in a disconnected state. For example, the second PA has no signal input, or the amplitude of the input signal is less than or equal to the first threshold.

[0135] In the transmitter 500 provided in this embodiment of the present application, Q first PAs transmit Q amplified second signals, and Q second PAs transmit Q amplified third signals. The amplified Q second signals and the amplified Q third signals can be synthesized in the spatial domain to obtain the amplified Q first signals, thereby reducing signal loss caused by synthesizing the amplified Q second signals and the amplified Q third signals in the circuit.

[0136] In a possible implementation, the transmitter 500 may further include a first antenna module and a second antenna module ( Figure 5 (not shown). A first PA is connected to multiple antenna elements in the first antenna module. A second PA is connected to multiple antenna elements in the second antenna module. Figure 5 Take a first PA connected to two antenna elements in a first antenna module and a second PA connected to two antenna elements in a second antenna module as an example. Furthermore, Q first PAs can send amplified Q second signals through the multiple antenna elements connected to the Q first PAs. Q second PAs can send amplified Q third signals through the multiple antenna elements connected to the Q second PAs. If Q is less than N, the remaining (NQ) first PAs can send amplified (NQ) first signals through the multiple antenna elements connected to the (NQ) first PAs. Through the above design, one PA is connected to multiple antenna elements and can send signals through the multiple antenna elements, which can improve signal gain.

[0137] In a possible implementation, the transmitter 500 may further include a first module 502. The baseband module 501 is connected to the N first PAs and the N second PAs via the first module 502. Figure 6 As shown. The first module 502 can be used to obtain Q second signals and Q third signals from the Q first signals. For example, the first module 502 determines Q first signals having amplitude values ​​greater than a first threshold from the N first signals, and obtains Q second signals and Q third signals from the Q first signals. Taking the kth first signal among the Q first signals as an example, the portion of the kth first signal having an amplitude value less than or equal to the second threshold is a second signal, and the portion of the kth first signal having an amplitude value greater than the second threshold is a third signal.

[0138] Furthermore, the first module 502 is further configured to send the Q second signals to the Q first PAs corresponding to the Q first signals, and to send the Q third signals to the Q second PAs corresponding to the Q first PAs. If Q is less than N, the first module 502 is further configured to send (NQ) first signals having amplitudes less than or equal to the first threshold to the remaining (NQ) first PAs.

[0139] In the embodiment of the present application, the second threshold value may be the same as or different from the first threshold value, and the embodiment of the present application does not limit this. In addition, the Q first PAs may correspond one-to-one with Q second threshold values, and the Q second threshold values ​​may be the same as or different, and the embodiment of the present application does not limit this.

[0140] As an example, the first module 502 can also be used to adjust the first threshold to obtain Q second thresholds corresponding to the Q first PAs. The Q second thresholds correspond one-to-one to the Q first PAs. For the specific implementation of the first module 502 adjusting the first threshold, please refer to the aforementioned description of the first module 102 adjusting the first threshold, and will not be repeated here.

[0141] It's worth noting that the amplitude of the first signal can vary, so the first module 502 needs to perform different processing on the first signal in different time periods. For example, consider the kth first signal among Q first signals, where the kth first signal corresponds to the ith first PA, and the ith first PA corresponds to the jth second PA. The amplitude of the kth first signal during the first time period is greater than a first threshold, while during the second time period, the amplitude of the kth first signal is less than or equal to the first threshold. Accordingly, during the first time period, the first module 502 can be configured to obtain a second signal and a third signal from the kth first signal, and to send the second signal to the ith first PA and the third signal to the jth second PA. The second signal and the third signal are used to synthesize the kth first signal. During the second time period, the first module 502 is configured to send the kth first signal to the ith first PA.

[0142] It is understandable that the second threshold corresponding to a first PA at different times may be the same or different, and this embodiment of the present application does not limit this. In addition, the first threshold may be variable or constant, and this embodiment of the present application does not limit this.

[0143] As another example, the first module 502 may also be configured to determine Q compensation values ​​for the Q third signals and compensate the Q third signals based on the Q compensation values. The Q third signals correspond one-to-one to the Q compensation values. One of the Q compensation values ​​may include a phase compensation value, an amplitude compensation value, or both a phase compensation value and an amplitude compensation value. The specific implementation process of the first module 502 compensating the Q third signals based on the Q compensation values ​​can be found in the description of the first module 102 above and will not be repeated here.

[0144] The transmitter 500 can compensate for the Q third signals by means of software. In another possible implementation method, the transmitter 500 can also perform phase compensation, or amplitude compensation, or phase and amplitude compensation on the Q third signals by means of hardware. For example, the multiple antenna elements connected to the first PA and the multiple antenna elements connected to the second PA corresponding to the first PA have the same phase center, so that the second signal sent by the first PA and the third signal sent by the second PA have the same phase. For another example, the transmitter 500 can also include N compensators, one compensator is connected to a second PA. The Q compensators connected to the Q second PAs can be used to perform phase compensation, or amplitude compensation, or phase and amplitude compensation on the Q third signals. If Q is less than N, the remaining (NQ) compensators do not work.

[0145] Through the above method, the transmitter 500 can perform phase and / or amplitude compensation on the Q third signals through software, hardware, or a combination of software and hardware. The implementation method is flexible and can reduce the difference between the compensated third signal and the second signal corresponding to the third signal, thereby improving the quality of the signal after the Q third signals and the Q second signals corresponding to the Q third signals are synthesized in the spatial domain.

[0146] As previously described, the transmitter 500 obtains Q second signals and Q third signals from Q first signals by software, i.e., the truncation of the input signal is implemented by the first module 502. In another possible implementation, the transmitter 500 may also obtain Q second signals and Q third signals from the Q first signals by hardware. For example, the transmitter 500 may include N signal truncation devices. The baseband module 501 is connected to N first PAs via N signal truncation devices, and one signal truncation device is connected to one first PA, such as Figure 7 shown. Figure 7 In the example, N signal interception devices are recorded as signal interception device 1, signal interception device 2, ..., signal interception device N. For example, signal interception device 1 is connected to PA 1_1, signal interception device 2 is connected to PA 1_2, and so on.

[0147] The baseband module 501 may also be configured to send N first signals to the N signal interception devices, and correspondingly, the N signal interception devices receive the N first signals.

[0148] Q signal interception devices connected to Q first PAs can be used to obtain Q second signals from the Q first signals and send the Q second signals to the Q first PAs. If Q is less than N, the remaining (NQ) signal interception devices can be used to send (NQ) first signals to the connected (NQ) first PAs. The amplitude values ​​of the (NQ) first signals are less than or equal to a first threshold. Taking signal interception device k as an example, signal interception device k receives the kth first signal and determines whether the amplitude value of the kth first signal is less than or equal to the first threshold. If the amplitude value of the kth first signal is less than or equal to the first threshold, signal interception device k sends the kth first signal to the i-th first PA connected to it. If the amplitude value of the kth first signal is greater than the first threshold, signal interception device k obtains the portion of the kth first signal whose amplitude value is greater than the second threshold, that is, obtains a second signal, and sends the second signal to the i-th first PA.

[0149] Furthermore, the Q second PAs can also be used to obtain Q third signals from the Q first signals. If Q is less than N, the remaining (NQ) second PAs do not operate. For example, taking the kth first signal as an example, if the amplitude of the kth first signal is less than or equal to a first threshold, the jth second PA does not operate. If the amplitude of the kth first signal is greater than the first threshold, the jth second PA obtains the portion of the kth first signal whose amplitude is greater than the second threshold, thereby obtaining a third signal.

[0150] In the above embodiment, the transmitter includes a baseband module, N first PAs, and N second PAs, with one first PA corresponding to one second PA. The baseband module can obtain N first signals from multiple data streams from multiple users, where Q of the N first signals have a peak-to-average ratio greater than a first threshold. The Q first PAs and Q second PAs can collaborate to transmit the Q first signals, thereby improving the efficiency of the Q first PAs and reducing the power consumption of the transmitter. Multiple data streams from multiple users can be transmitted using a small number of PAs. Furthermore, the transmitter has a simple structure and is easy to implement.

[0151] The transmitter provided in the embodiment of the present application is introduced above, and the signal sending method provided in the embodiment of the present application is introduced next.

[0154] Among them, one first signal corresponds to two or more data streams in the M data streams. One data stream corresponds to two or more first signals in the N first signals. The N first signals correspond one to one with the N first PAs. In an embodiment of the present application, the amplitude values ​​of the N first signals are different, for example, the amplitude values ​​of Q first signals in the N first signals are greater than the first threshold. Among them, N and M are integers greater than 1. Q is an integer greater than 0 and less than or equal to H. H is the number of second PAs included in the transmitter 100. H is an integer greater than 0 and less than N. The first threshold can be pre-set, or determined based on the performance curves of the N first PAs, etc., and this embodiment does not limit this. In addition, please refer to the specific implementation process of the value of N and the value of H. Figure 1 The relevant description in will not be repeated here.

[0157] Among them, a first PA and a second PA having a corresponding relationship can cooperate to send the first signal corresponding to the first PA, that is, the first PA is used to amplify the portion of the first signal whose amplitude value is less than or equal to the second threshold, and the second PA is used to amplify the portion of the first signal whose amplitude value is greater than the second threshold. For the specific implementation process of step S802, please refer to the aforementioned Figure 1 The relevant description in will not be repeated here.

The third signal corresponding to the jth second PA among the Q second PAs and the second signal corresponding to the ith first PA can be used to synthesize the kth first signal among the Q first signals. The ith first PA and the jth second PA have the corresponding relationship determined in step S802.

[0164] For example, the transmitter 100 may simultaneously perform steps S803, S804, and S805. That is, the transmitter 100 may simultaneously transmit the amplified Q second signals through the Q first PAs, transmit the amplified (NQ) first signals through the remaining (NQ) first PAs, and transmit the amplified Q third signals through the Q second PAs. However, the embodiments of the present application are not limited thereto.

[0165] In the embodiment of the present application, the transmitter 100 transmits Q amplified second signals and Q amplified third signals. The Q amplified second signals and the Q amplified third signals can be synthesized in the spatial domain to obtain the Q amplified first signals, thereby reducing signal loss caused by synthesizing the Q amplified second signals and the Q amplified third signals in the circuit.

[0166] As an example, the transmitter 100 may obtain Q first signals having amplitude values ​​greater than a first threshold from N first signals; obtain Q second signals and Q third signals from the Q first signals; and transmit the amplified Q second signals through the Q first PAs corresponding to the Q first signals, transmit the amplified (NQ) first signals through the remaining (NQ) first PAs, and transmit the amplified Q third signals through the Q second PAs corresponding to the Q first PAs. For the specific implementation process, please refer to Figure 1 The relevant description in will not be repeated here.

[0168] As another example, the Q second thresholds corresponding to the Q first PAs may be the same or different, and the embodiment of the present application is not limited thereto. For example, the transmitter 100 may adjust the first threshold to obtain the second threshold. For the specific implementation process, please refer to Figure 1 The relevant description in will not be repeated here.

[0169] As another example, the amplitude value of the first signal may be variable. Taking the kth first signal among the Q first signals, the kth first signal corresponds to the ith first PA, and the ith first PA corresponds to the jth second PA as an example, the amplitude value of the kth first signal in the first time period is greater than the first threshold value, and the amplitude value of the kth first signal in the second time period is less than or equal to the first threshold value.
