Description

Technical Field

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

[0002] In order to meet the continuous development of wireless access services, communication devices have higher and higher requirements for service load capacity, the working bandwidth of communication devices has become larger, the number of transceiver channels has increased, and the transmission power has increased, which has led to higher and higher power consumption of communication devices. Among them, for the power consumption of the active antenna unit (AAU), for scenarios with high service load, the power consumption of the power amplifier module accounts for a higher proportion; while for scenarios with low service load, the power consumption of the intermediate frequency module and the small signal processing before the power amplifier accounts for a higher proportion of the AAU power consumption. Therefore, in the field of energy-saving technology, it is necessary not only to improve the efficiency of the power amplifier and reduce the power consumption of the power amplifier; when the service load is low, it is also necessary to reduce the basic power consumption generated by the intermediate frequency module and small signal processing.

[0003] Existing beamforming technologies include digital beamforming (ABF), digital hybrid beamforming (AHBF), and analog beamforming (DBF) or digital hybrid beamforming (DHBF) technologies. In the ABF / AHBF architecture, each IF module is connected to multiple RF modules, so the number of IF channels is usually less than the number of RF channels; while in the DBF / DHBF architecture, each RF module is connected to one IF module, and the number of IF channels is usually equal to the number of RF channels.

[0004] Currently, the power consumption of AAU can be reduced by shutting down some channels of the communication device, such as shutting down some intermediate frequency channels and / or radio frequency channels. However, shutting down some channels will make the antenna array corresponding to the channel unavailable, thereby losing the antenna array gain and reducing the communication performance. Summary of the invention

[0005] The embodiments of the present application provide a communication method and device for reducing AAU power consumption without losing antenna array gain.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0063] In the embodiment of the present application, the chip system may be composed of a chip, or may include a chip and other discrete devices.

[0064] Before introducing the embodiments of the present application, a brief introduction to the related technologies of beamforming is first given.

[0065] Beamforming, also known as beamforming and spatial filtering, is a signal processing technology that uses a sensor array to send and receive signals in a directional manner. Beamforming technology adjusts the parameters of the basic units of the phase array so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference. Therefore, beamforming can focus the antenna energy of the communication device to point to a specific user. Beamforming can be used for both signal transmission and signal reception.

[0066] At present, beamforming technology is divided into DBF / DHBF and ABF / AHBF technology. Figure 3 As shown in FIG. 1 , the DBF / DHBF architecture in the communication device includes m channels composed of baseband, IF, RF and antenna modules, including m IF modules, each of which is connected to a RF module. Therefore, the number of RF modules in the DBF / DHBF architecture is equal to the number of IF modules, that is, the number of RF channels is equal to the number of IF channels.

[0067] Among them, the intermediate frequency module is used for intermediate frequency signal processing, which may include analog to digital converter (ADC), digital to analog converter (DAC), intermediate frequency amplification, mixing, attenuation and other functions.

[0068] The RF module is used for RF signal processing, which may include functions such as filtering, amplification, phase shifting, and attenuation. The RF module may specifically be a transmitter-receiver responsible for transmitting (Transmitter, Tx) high-frequency analog signals to the antenna, or receiving (Receiver, Rx) high-frequency analog channels from the antenna. In the embodiment of the present application, the RF module may be referred to as a TRX module. Among them, the TRX module mainly includes a phase and amplitude control circuit; optionally, a power amplifier (Power Amplifier, PA) or a low noise amplifier (Low Noise Amplifier, LNA) may also be integrated in the RF module, wherein the main function of PA and LNA is to amplify the power of "small signals", PA is mainly used to send signals, and LNA is mainly used to receive signals. Alternatively, PA or LNA may also be deployed separately as a power amplifier module, independent of the RF module deployment, and this application does not limit this.

[0069] It should be noted that in the embodiments of the present application, the signal processing at each stage can be called a channel, that is, the channel for signal processing by the RF module can be called a RF channel, and the channel for signal processing by the IF module can be called an IF channel.

[0070] like Figure 4 As shown, the ABF / AHBF architecture in the communication device includes a IF modules, each of which is connected to b RF modules, where a and b are both positive integers greater than 1. Therefore, the number of IF channels in the ABF / AHBF architecture is usually less than or much less than the number of RF channels.

[0071] In order to reduce the power consumption of the communication device and improve the communication efficiency, considering that the power consumption distribution of the communication device, the power consumption of the AAU accounts for about 90% of the total power consumption, such as Figure 5 As shown. The power consumption of the AAU module may include the power supply, intermediate frequency module, power amplifier, and other power consumption of small signal processing before the power amplifier. According to relevant statistical data, the power consumption proportion of each module of the AAU changes significantly under different business load power consumption of the communication device.

[0072] For example, Figure 5 The statistics shown show that at 100% business load, the power amplifier power consumption accounts for the highest proportion, about 58%; the digital intermediate frequency and small signal power consumption accounts for about 37%. At 30% business load, the power amplifier power consumption accounts for 37%, and the digital intermediate frequency and small signal power consumption accounts for 59%. Under no-load conditions, that is, when there is no business load, the power amplifier power consumption accounts for only 15%, and the power consumption of digital intermediate frequency and small signal accounts for 80%.

[0073] Therefore, in the field of AAU energy-saving technology, it is necessary not only to improve the efficiency of the power amplifier but also to reduce the power consumption of the power amplifier. When the business load is low, it is even more necessary to reduce the basic power consumption of small signal processing and intermediate frequency signals. However, from the above-mentioned existing communication device architecture, it can be seen that if some intermediate frequency channels are turned off to reduce power consumption, the RF module and antenna array connected to the closed intermediate frequency channel will also be turned off and unavailable, thereby losing antenna gain and reducing communication performance.

[0074] Next, the communication method and communication device involved in the embodiments of the present application are introduced.

[0075] The present application provides a communication method, which introduces code domain freedom so that a communication device can switch freely between a full connection state and an energy-saving state according to a service load indicator. For example, when the service load is low, the energy-saving state can be entered. By shutting down some intermediate frequency channels in N beamforming channels, power consumption can be reduced without losing antenna gain.

[0076] like Figure 6 As shown, the method may include the following steps.

[0077] 601: When the communication device operates in the first mode, N channels perform direct processing on input signals.

[0078] For example, the method can be applied to Figure 7 The communication device 700 shown in the figure includes N beamforming channels, wherein a beamforming channel refers to a signal processing channel from baseband to antenna array. Figure 7 As shown, the information processing channel from the baseband to the antenna array may include intermediate frequency, radio frequency and other signal processing processes. In the embodiment of the present application, the channel for processing the signal by the intermediate frequency module may be called an intermediate frequency channel, and the channel for processing the signal by the radio frequency module may be called a radio frequency channel. In addition, optionally, the communication device may also include a channel for power amplification processing of the signal by the power amplifier module, which may be called a power amplifier channel; or the power amplifier module may be integrated in the radio frequency module.

[0079] When the communication device operates in the first mode, Figure 7 All intermediate frequency and radio frequency channels in the communication device shown are operating normally, and all N channels perform direct-through processing on input signals.

[0080] In one embodiment, the first mode may mean: when the communication device determines that it is currently under a high business load, it enters a performance mode working state, that is, a fully connected working state, all intermediate frequency modules and radio frequency modules in the communication device are connected, and the intermediate frequency channel and the radio frequency channel are working normally.

[0081] 602: When the communication device operates in the second mode, the N channels perform spread spectrum and despread spectrum processing on the input signal; and turn off some intermediate frequency modules.

[0082] Among them, N channels can share one or more intermediate frequency modules that are not closed to perform spread spectrum and despreading processing on the input signal. Spread spectrum refers to a signal modulation method that can expand the bandwidth of the input signal through a specific code word sequence to obtain a spread spectrum signal. Exemplarily, the spread spectrum processing can be performed by performing an inner product operation on a series of orthogonal code word sequences and the baseband modulation signal. Despreading refers to the inverse processing of spread spectrum modulation, which processes the spread spectrum signal through a specific code word sequence and restores it to the signal of the original bandwidth.

[0083] Exemplarily, the communication device includes M intermediate frequency modules, that is, includes M intermediate frequency channels. When the communication device operates in the second mode, i intermediate frequency channels among the M intermediate frequency channels can be closed, and the communication device can share the remaining intermediate frequency channels among the M intermediate frequency channels except the closed i intermediate frequency channels, that is, Mi intermediate frequency channels. Wherein, N, M and i are all positive integers greater than 1.

[0084] From the aforementioned beamforming architecture, it can be seen that each IF module can be connected to one or more RF modules, and each RF module can be connected to an antenna array. Therefore, N is greater than or equal to M. For the DBF / DHBF architecture, each IF module is connected to one RF module; for the ABF / AHBF architecture, each IF module is connected to multiple RF modules, where the number of RF modules connected to each IF module can be the same or different.

[0085] For example, Figure 7 As shown, when the communication device operates in the second mode, some of the multiple intermediate frequency channels in the communication device can be closed, and N channels can share one or more intermediate frequency modules that are not closed.

[0086] For example, Figure 8 As shown, taking the DBF / DHBF architecture as an example, the communication device includes 4 intermediate frequency channels. In the second mode, the communication device can close 3 of the intermediate frequency channels and only retain one of the intermediate frequency channels, wherein the 4 beamforming channels can share the intermediate frequency module that is not closed.

[0087] In one embodiment, the second mode may mean: when the communication device determines that it is currently in a medium / low business load, it enters an energy-saving mode, that is, a working state in which some intermediate frequency channels are closed. The communication device closes some intermediate frequency channels, and N channels can share some intermediate frequency modules that are not closed.

[0088] In one embodiment, the judgment basis for switching the communication device to the first mode or the second mode can be determined by comparing the current business load index with a preconfigured threshold. For example, the communication device is preconfigured with a first threshold, and when the current business load index of the communication device is greater than or equal to the first threshold, it is determined that the communication device is working in the first mode. In addition, the communication device is preconfigured with a second threshold, and when the current business load index of the communication device is less than or equal to the second threshold, it is determined that the communication device is working in the second mode. Exemplarily, the first threshold and the second threshold may be the same or different.

[0089] For example, the first threshold and the second threshold can be 30%. When the current business load index of the communication device is greater than or equal to 30%, it works in the first mode and does not close the intermediate frequency channel. If the current business load index of the communication device is less than 30%, the communication device switches to the second mode and closes part of the intermediate frequency channels, thereby saving power consumption. For another example, the first threshold is 40% and the second threshold can be 30%. When the current business load index of the communication device is greater than or equal to 40%, it works in the first mode and does not close the intermediate frequency channel. If the current business load index of the communication device is less than or equal to 30%, the communication device switches to the second mode and closes part of the intermediate frequency channels, thereby saving power consumption.

[0090] Furthermore, in one embodiment, the number of IF channels closed by the communication device may be associated with the current service load index; or the current service load index of the communication device may be associated with the ratio of the number of closed IF channels to the total number of IF channels. In other words, the communication device may determine how many IF channels to close based on the current service load index.

[0091] For example, the service load index of the communication device may be negatively correlated with the number of closed intermediate frequency channels. That is, the lower the current service load index of the communication device, the more intermediate frequency channels the communication device closes; conversely, the higher the current service load index of the communication device, the fewer intermediate frequency channels the communication device closes. For another example, the service load index of the communication device is negatively correlated with the ratio of the number of closed intermediate frequency channels to the total number of intermediate frequency channels.

[0092] Exemplarily, if the second threshold is 50%, when the current business load index of the communication device is 100%, the number of intermediate frequency channels closed by the communication device is 0; if the current business load index of the communication device is 50%, the number of intermediate frequency channels closed by the communication device is 1; if the current business load index of the communication device is 30%, the number of intermediate frequency channels closed by the communication device is 2; if the current business load index of the communication device is 10%, the number of intermediate frequency channels closed by the communication device is 3; if the current business load index of the communication device is 0, the number of intermediate frequency channels closed by the communication device is 4.

[0093] In one embodiment, in the first mode, each of the N channels of the communication device is loaded with a constant codeword through a modulation module. In the second mode, each of the N channels of the communication device is loaded with a non-constant codeword through a modulation module.

[0094] That is to say, the communication device includes a modulation module for loading code words, and the communication device can realize function switching through code word transformation of the modulation module. Specifically, each of the N channels of the communication device includes a modulation module. When the communication device operates in the first mode, the modulation module can be used to load a constant code word, and the modulation module performs direct-through processing on the signal when the constant code word is used; when the communication device operates in the second mode, the modulation module can be used to load a non-constant code word, and the modulation module performs spread spectrum and despread processing on the signal when the non-constant code word is used.

[0095] Among them, the constant codeword refers to the output codeword that is constant, for example, the codeword can be {0, 0, 0, 0, 0, ...}, or the codeword is {1, 1, 1, 1, 1, ...}, or the codeword is {0, 1, 0, 1, 0, 1, ...}, etc. Conversely, the non-constant codeword refers to the output codeword that is not constant, for example, Walsh code, pseudo-random code, etc. are non-constant codewords.

[0096] Further, in one embodiment, the modulation module may include a modulator and a demodulator, wherein the modulator is used to load a codeword and perform modulation processing on an input signal, and the demodulator is used to load a codeword and perform demodulation processing on an input signal. Exemplarily, if the modulator loads a non-constant codeword and can perform spread spectrum processing on the signal, the demodulator can load the non-constant codeword to perform despread processing on the spread spectrum signal.

[0097] For example, Fig. 9 As shown in the figure, taking the DBF / DHBF architecture as an example, the modulator can be distributed between the baseband and the intermediate frequency module of each channel in the N channels. When the communication device sends a signal, the input signal of the modulator can be the signal output by the baseband, and the output signal of the modulator can be the input signal of the intermediate frequency module. The demodulator can be distributed between the intermediate frequency module and the radio frequency module of each channel in the N channels.

[0098] In this implementation, if the communication device is used to transmit a signal, the input signal of the demodulator can be the signal output by the intermediate frequency module. If the communication device is used to receive a signal, the output signal of the demodulator can be the input signal of the intermediate frequency module.

[0099] At this time, if Fig. 9 As shown in (a), when the communication device operates in the first mode (such as the performance mode), all intermediate frequencies operate normally. Fig. 9 As shown in (b), when the communication device operates in the second mode (such as the energy-saving mode), intermediate frequencies 2, 3 and 4 can be turned off, and only intermediate frequency 1 is retained for normal operation. Multiple channels can share the intermediate frequency 1 that is not turned off, thereby saving power consumption without losing the antenna array gain.

[0100] Or, in another implementation, such as Fig.10 As shown, taking the DBF / DHBF architecture as an example, the demodulator can be distributed between the RF module and the antenna array of each channel in the N channels.

[0101] In this implementation, Fig.10 As shown, if the communication device is used to transmit a signal, the input signal of the demodulator can be the signal output by the radio frequency module. If the communication device is used to receive a signal, the signal output by the demodulator can be the input signal of the radio frequency module.

[0102] At this time, if Fig.10 As shown in (a), when the communication device operates in the first mode (such as the performance mode), all intermediate frequencies operate normally. Fig.10 As shown in (b), when the communication device operates in the second mode (such as the energy-saving mode), intermediate frequencies 2, 3 and 4 can be turned off, and only intermediate frequency 1 is kept to operate normally. Multiple channels can share the intermediate frequency 1 that is not turned off and the RF module connected to intermediate frequency 1, thereby saving power consumption without losing the antenna array gain.

[0103] In addition, in another possible implementation, the PA / LNA can be arranged separately, or the PA / LNA can be integrated with the RF module. Fig. 9 or Fig.10 In the communication device shown, the RF module may also be integrated with a PA / LNA. Alternatively, if the PA / LNA is arranged separately, the communication device may further include a PA / LNA between the intermediate frequency module and the antenna array. In this implementation, if the communication device is used to transmit a signal, the input signal of the demodulator may be a signal output by the PA. If the communication device is used to receive a signal, the signal output by the demodulator is an input signal of the LNA.

[0104] In one embodiment, the communication device includes a processing module for implementing the function of the modulation module. In addition, the communication device may also include a decision module, which is used to determine whether the current communication device is working in the first mode or the second mode and whether switching is required. Alternatively, the above-mentioned decision function may also be integrated in the processing module of the communication device, which is not limited in this application.

[0105] In one embodiment, in the above-mentioned embodiments of the present application, the switching between the first mode and the second mode can be specifically achieved by a modulator + demodulator, a switching circuit, and a power divider (also called a power distributor) + combiner. Among them, the modulator + demodulator is used to load codewords, and the switching between direct processing and spread spectrum / despread processing is achieved by loading the transformation of different codewords. The switching circuit is used to connect or close the intermediate frequency module. The power divider + combiner is used to realize the power distribution and merging of the communication device working in the second mode, wherein the power divider can be used to divide the energy of one input signal into two or more outputs, and the combiner can be used to synthesize the energy of multiple signals into one output.

[0106] For example, taking the DBF / DHBF architecture as an example, Fig.11 As shown, when switch 1 is on A, it means that intermediate frequency 1 is connected; when switch 1 is on B, it means that intermediate frequency 1 is disconnected. Similarly, when switch 5 is on A, it means that intermediate frequency 2 is turned off and intermediate frequency 1 is shared through the combiner; when switch 5 is on B, it means that intermediate frequency 2 is connected. In addition, by controlling switch 3 to be on A, switch 4 to be on A, and switch 6 to be on A, the signal processed and output by intermediate frequency 1 is divided to different demodulators through the power divider, and the signal is sent through different antenna arrays.

[0107] Similarly, the communication device works in the first mode, and a constant codeword can be loaded through the modulator, and the modulator performs direct processing. In addition, by controlling the switch circuit, intermediate frequencies 1, 2, 3, and 4 are connected, so that each intermediate frequency channel and radio frequency channel work normally. At this time, the signal bandwidth of each channel is normal, such as the signal bandwidth is represented by BW. Exemplarily, the signal bandwidth of each channel can be BW=200MHz.

[0108] If the communication device switches to the second mode, a non-constant codeword can be loaded through the modulator to perform spread spectrum and despreading processing; in addition, part of the intermediate frequency channel can be closed by controlling the switch circuit. For example, Fig.11 As shown, IF 1 can be kept connected, and IFs 2, 3, and 4 can be turned off. At this time, the signal bandwidth of each channel can be BW / N, for example, N=4, then the signal bandwidth is 50MHz. In the above implementation, the IF bandwidth after spectrum spread is not increased, and when the same PA is used, the power spectrum density within the bandwidth increases, and the signal-to-noise ratio is improved.

[0109] In a possible implementation, the demodulator may also be located between the RF module and the antenna array, such as Fig.12 As shown, when the communication device is used to send signals, the demodulator processes the sending signals before the RF module, and the output signal of the RF module is the input signal of the demodulator; when the communication device is used to receive signals, the demodulator processes the receiving signals after the RF module, and the input signal of the RF module is the output signal of the demodulator. Fig.11 Similar to the above embodiment, the communication device can be switched between the first mode and the second mode.

[0110] In the above implementation, by introducing the code domain degree of freedom into the DBF / DHBF system, the communication device can dynamically adjust the working mode according to the change of the business load, and switch between the first mode and the second mode by controlling the switching circuit and the transformation of the modulator loaded codeword, so that the communication device switches to the second mode and closes part of the intermediate frequency channel in the scenario of medium and low business load, thereby achieving the purpose of reducing power consumption without losing the antenna array gain and reducing system performance. In the high business load scenario, the communication device does not change the original system architecture and signal bandwidth, and does not affect the system performance.

[0111] It should be noted that the above embodiments only use the DBF / DHBF architecture as an example, but this does not limit the scope of implementation of the present application. The present application is also applicable to the ABF / AHBF architecture, and the implementation method is similar to the above. The implementation method applied to the ABF / AHBF architecture will be introduced below in conjunction with specific embodiments.

[0112] In the DBF / DHBF architecture, one IF module in the communication device is connected to one RF module, while in the ABF / AHBF architecture, one IF module is connected to multiple RF modules. Fig.13 In the example of the ABF / AHBF architecture shown, M is 2, which includes 2 intermediate frequency modules, each of which is connected to 2 radio frequency modules, so N is 4, which includes 4 beamforming channels in total. By adding functions such as modulators, demodulators, switch circuits, combiners, and frequency dividers, the communication device can dynamically adjust whether to work in the first mode or the second mode according to changes in business load.

[0113] Specifically, Fig.13 When both switch 1 and switch 2 are turned to B, the modulation module uses a constant codeword signal to pass through, and the communication device switches to the first mode, maintaining the system performance of the original ABF / AHBF architecture without being affected. Fig.13When switches 1 and 2 are both turned to A, the modulation module uses non-constant codewords to spread and despread the signal, and the communication device switches to the second mode. Under the same number of channels, the system architecture can be changed from ABF / AHBF to DBF / DHBF, without increasing the number of channels but with a faster transmission rate and improved communication performance; in addition, the time required to transmit the same data is shorter, and the shutdown timing accounts for a larger proportion, which can reduce the average power consumption, so energy saving and efficiency improvement can be achieved in this scenario. In addition, in the second mode, each digital channel of the communication device only sends part of the bandwidth (such as BW / N, if N is 4), does not increase the intermediate frequency bandwidth after spread spectrum, and can also enhance the power spectrum density of the transmitted signal, and the scheduling of time domain and frequency domain resources is more flexible.

[0114] In a possible implementation, in the above communication device, the positions of the radio frequency module and the demodulator can be interchanged. Fig.14 In the communication device shown, the RF module may not include PA / LNA, and the PA / LNA is between the IF module and the RF module. Fig.14 In the communication device shown, the positions of the RF module and the demodulator can be interchanged.

[0115] In addition, the present application also provides an implementation method, which is applied to the DBF / DHBF architecture, wherein each intermediate frequency channel is connected to multiple radio frequency channels, and a modulation module and a switching circuit are added to each intermediate frequency channel, wherein the modulation module is used to load codewords, and can work in both a pass-through mode and a spread spectrum and despreading mode; the switching circuit is used to realize the switching of the working mode of the communication device.

[0116] like Fig.15 As shown, the function switching of the communication device can be realized by loading the codeword transformation on the modulation module. When the modulation module adopts a constant codeword, the signal is directly processed, and the switching of the working mode is realized by switching the switch circuit. The communication device works in the first mode, each intermediate frequency channel works normally, and the system works in the performance mode. When the modulation module adopts a non-constant codeword, the signal is spread and despread, and the switching of the working mode is realized by switching the switch circuit. The communication device works in the second mode, and the intermediate frequency module that is not connected can be turned off, such as Fig.15 The IF 2 can be turned off and the system architecture works in energy-saving mode.

[0117] In another embodiment, Fig.15 The RF module in the embodiment may include phase and amplitude control circuits, but not PA / LNA, wherein PA / LNA may also be deployed between the IF module and the demodulator. Fig.16 As shown, the PA / LNA can be deployed separately between the demodulator and the RF module. Alternatively, in another implementation, the PA / LNA can also be deployed between the IF module and the demodulator.

[0118] In the above-mentioned implementation mode of the present application, by introducing the code domain degree of freedom into the ABF / AHBF system, the communication device can dynamically adjust the system working mode according to the change of business load. Specifically, in the high business load scenario, the modulation module of the communication device adopts a constant codeword to directly process the signal, without changing the original architecture and signal bandwidth, and without affecting the system performance; in the medium and low business load scenario, the modulation module adopts a non-constant codeword to spread and despread the signal. The communication device can close some intermediate frequency channels to reduce system power consumption without losing the antenna array gain and affecting the system performance. In addition, each digital channel only sends part of the bandwidth (such as BW / N, such as N can be 2), without increasing the intermediate frequency bandwidth after spreading, and at the same time can also enhance the power spectrum density of the transmitted signal.
