Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a signal processing method and related devices. Background Art

[0002] In communication systems, beamforming (BF) can focus transmission energy in a specific direction, increasing the transmit power in one direction while reducing it to near zero in other directions. This extends the communication range in the desired direction while avoiding interference in other directions. Beamforming includes digital beamforming (DBF), analog beamforming (ABF), and hybrid digital and analog beamforming (HBF).

[0003] In the HBF architecture, since the common channel and the service channel are controlled by the same phase shifter, when the service channel adjusts the antenna weights to change the beam direction, the common channel beam direction also changes accordingly. To ensure optimal service channel performance, the antenna weights need to be adjusted frequently. However, frequent adjustments to the antenna weights cause the common channel's transmit beam to fluctuate frequently. The common channel is mainly used by terminal devices for cell measurement and channel estimation, so the beam needs to remain stable.

[0004] In order to keep the transmission beam of the common channel stable, the existing technology sends the common channel signal only to the radio frequency channel corresponding to a group of antenna arrays with fixed phase shifters. That is, the common channel only uses a part of the radio frequency channels of the cell. Although the signal transmission beam of the common channel remains stable, the total transmission power of the common channel is only the sum of the power of a part of the radio frequency channels, resulting in a decrease in the signal transmission power and coverage range of the common channel. Summary of the Invention

[0005] The embodiments of the present application provide a signal processing method and related devices for improving the transmission power of a signal and the coverage range of a beam.

[0006] The first aspect of the embodiment of the present application provides a signal processing method, which is executed by a base station, or can be executed by a component of the base station, such as a processor, chip, or chip system of the base station, or can be implemented by a logic module or software that can realize all or part of the server function. The method provided in the first aspect includes: receiving a first signal from a radio frequency channel, the first signal is sent by a signal source through the radio frequency channel, the radio frequency channel is connected to a first phase shifter and a second phase shifter through a baseband module and a power bridge respectively, the first phase shifter is a phase shifter with dynamic phase adjustment, the second phase shifter is a phase shifter with fixed phase, the destination antenna array of the first signal is the antenna array corresponding to the first phase shifter, that is, the first signal is originally a signal of the first phase shifter, and the base station sends the first signal processed by the power bridge to the second phase shifter.

[0007] In the embodiment of the present application, a power bridge is introduced into the base station. By designing the bridge parameters of the power bridge and the baseband weights of different channels, the signals of different channels are weighted by the baseband weights and sent to the designated phase shifter after passing through the power bridge. That is, the signal of the phase shifter whose sending phase is dynamically adjusted can be converged to the RF channel where the phase shifter with a fixed phase is located, thereby reducing signal fluctuations while improving the signal transmission power without decreasing and the coverage range of the beam without shrinking.

[0008] Based on the first aspect, in one possible implementation, the base station receives a second signal from a radio frequency channel, the destination antenna array for the second channel is the antenna array corresponding to the second phase shifter, and the first and second signals are processed by a power bridge. The first and second signals may be signals from different radio frequency channels received simultaneously by the base station.

[0009] In the embodiment of the present application, the base station sends the first signal originally sent to the phase shifter with dynamic phase adjustment to the phase shifter with fixed phase through a power bridge. Compared with the scheme of sending the second signal only to the phase shifter with fixed phase and not sending the first signal to the phase shifter with dynamic phase adjustment, the transmission power of the antenna array is increased and the coverage range of the beam is improved.

[0010] Based on the first aspect, in a possible implementation manner, processing the first signal and the second signal through the power bridge includes superimposing the first signal on the second signal through the power bridge.

[0011] In the embodiment of the present application, the power of the first signal can be superimposed on the power of the second signal through a power bridge, thereby improving the signal transmission power of the base station antenna array.

[0012] Based on the first aspect, in a possible implementation manner, superimposing the first signal on the second signal through the power bridge includes superimposing the first signal on the second signal based on a baseband weight of a radio frequency channel and a power bridge parameter of the power bridge.

[0013] In the embodiment of the present application, the base station can design the bridge parameters of the channel pair power bridge, superimpose the power of the first signal and the power of the second signal and send them to a phase-fixed phase shifter, thereby improving the feasibility of the solution.

[0014] Based on the first aspect, in one possible implementation, the radio frequency channel includes a common channel and a traffic channel. The first signal can be a radio frequency signal of the common channel or a radio frequency signal of the traffic channel, and the baseband weights of the common channel and the traffic channel can be the same or different.

[0015] For common channels, the common channels are mapped to all RF channels in the baseband and weightedly sent using the corresponding common channel baseband weights. For the RF channels originally connected to the antenna array with a fixed phase shifter, the second signal sent by it passes through the power bridge and is still sent to the corresponding antenna array with a fixed phase shifter. For the RF channels originally connected to the antenna array with a dynamically adjustable phase shifter, the first signal sent by it passes through the power bridge and is converged to the antenna array with a fixed phase shifter and sent in superposition with the second signal. That is, the signal power of the common channel received by the antenna array with a fixed phase shifter is doubled, while the antenna array with a dynamically adjustable phase shifter does not send the common channel signal.

[0016] For the service channel, the service channel is mapped to all RF channels in the baseband and sent weighted using the corresponding service channel baseband weights. The second signal that reaches the corresponding antenna array with a fixed phase after passing through the power bridge, and the first signal that reaches the corresponding antenna array with a dynamically adjustable phase after passing through the power bridge, are consistent with the service channel signal that reaches the corresponding antenna array when the power bridge and the corresponding baseband weights are not used.

[0017] In the embodiment of the present application, the base station can design the bridge parameters and baseband weights according to the transmission requirements of the public channel signals and the service channel signals, thereby improving the applicability of the solution.

[0020] The processing unit is configured to send the first signal processed by the power bridge to the second phase shifter.

[0021] Based on the second aspect, in one possible implementation, the interface unit is further configured to receive a second signal from the radio frequency channel, and the destination antenna array of the second channel is the antenna array corresponding to the second phase shifter;

[0022] The processing unit is specifically configured to process the first signal and the second signal through the power bridge.

[0024] Based on the second aspect, in a possible implementation manner, the processing unit is specifically configured to superimpose the first signal on the second signal based on a baseband weight of the radio frequency channel and a power parameter or bridge parameter of the power bridge.

[0038] The embodiments of the present application provide a signal processing method and related devices for improving the transmission power and coverage of a signal.

[0039] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0041] Below, some terms in this application are explained to facilitate understanding by those skilled in the art.

[0042] Beamforming (BF) is a signal preprocessing technology based on antenna arrays. By adjusting the parameters of the basic units of the phase array, signals at certain angles achieve constructive interference, while signals at other angles achieve destructive interference.

[0043] Digital beamforming (DBF) means that when the baseband maps the original transmission data to the RF channel, different weights are superimposed on different RF channels, and different transmission beams are ultimately formed through the antenna array.

[0044] Analog beamforming (ABF) involves adding independent digitally controlled phase shifters to different array elements in an antenna array. These phase shifters control the phase difference between signals reaching different array elements, thereby controlling the shape of the transmit beam ultimately formed by multiple array elements. Different phases in the phase shifter configurations result in different transmit beams in the antenna array.

[0045] Hybrid digital and analog beamforming (HBF) refers to beamforming that uses both digital beamforming and analog beamforming.

[0046] The signal processing method and related devices provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0047] See also Figure 1 , Figure 1 Schematic diagram of the architecture of a communication system to which a signal processing method is applied according to an embodiment of the present application. Figure 1 As shown, the communication system 100 includes an antenna array 101, a phase shifter 102, a power bridge 103, and a baseband module 104. The antenna array 101 includes multiple identical single antennas arranged in a certain pattern, and is used to send radio frequency signals to a terminal.

[0048] Phase shifter 102 is used for analog beamforming. It controls the phase difference between the same signal reaching different antenna array elements, thereby controlling the shape of the transmit beam ultimately formed by the multiple antenna array elements. Different phases configured with the phase shifter result in different transmit beams of the antenna array. The phases of the phase shifters configured for different antenna array elements in analog beamforming are called antenna weights.

[0049] Power bridge 103 transmits baseband weighted signals from different channels to designated phase shifters. Baseband module 104 performs analog beamforming. When mapping signals from a signal source to RF channels, baseband module 104 applies different weights to different RF channels. In digital beamforming, the weights applied to different RF channels are called baseband weights. Ultimately, different transmit beams are formed through the antenna array.

[0051] 201. A base station receives a first signal from a radio frequency channel, where the destination antenna array of the first signal is the antenna array corresponding to the first phase shifter.

[0052] The base station receives a first signal from a radio frequency channel, which is connected to a first phase shifter and a second phase shifter through a baseband module and a power bridge, respectively. The first phase shifter is a phase shifter with dynamically adjusted phase, and the second phase shifter is a phase shifter with fixed phase.

[0053] The antenna arrays in the embodiments of the present application are divided into two groups, one of which has phase shifters with fixed phases, and the other has phase shifters with dynamically adjustable phases. The destination antenna array for the first signal is the antenna array corresponding to the first phase shifter.

[0054] In the embodiment of the present application, the radio frequency channel includes a common channel and a service channel, wherein the common channel is mainly used for the terminal device to perform cell measurement or signal estimation, the common channel is such as the transmission channel of the cell reference signal (CRS) or the transmission channel of the synchronization signal and the physical broadcast channel block (PBCH), and the service channel is such as the physical downlink shared channel (PDSCH) for transmitting service data.

[0055] When the base station receives a common channel signal, it maps the signal to all antenna arrays, including the antenna array corresponding to the first phase shifter and the array corresponding to the second phase shifter. The signal mapped to the antenna array corresponding to the first phase shifter is the first signal, and the signal mapped to the antenna array corresponding to the second phase shifter is the second signal.

[0056] See also Figure 3 , Figure 3 A schematic diagram of a base station system provided in an embodiment of the present application. Figure 3In one example shown, antenna arrays are divided into two groups, one of which is connected to a fixed-phase phase shifter, and the other is connected to a dynamically adjustable phase shifter. The base station receives a signal sent by a signal source through a radio frequency channel. The signal is sent to the antenna arrays corresponding to different phase shifters via a baseband module and a power bridge. The signal includes a first signal and a second signal. The first signal is destined for the antenna array corresponding to the dynamically adjustable phase shifter, while the second signal is destined for the antenna array corresponding to the fixed-phase phase shifter.

[0057] 202. The base station sends the first signal processed by the power bridge to the second phase shifter.

[0058] The base station sends the first signal, processed by the power bridge, to the second phase shifter. Specifically, the first signal's original destination antenna array is the antenna array corresponding to the first phase shifter. After the first signal is processed by the power bridge, the first signal's destination antenna array is adjusted from the antenna array corresponding to the first phase shifter to the antenna array corresponding to the second phase shifter. Specifically, the base station designs the bridge parameters and baseband weights so that the power of the first signal in the RF channel originally corresponding to the first phase shifter is zero, and the power of the first signal is concentrated in the RF channel corresponding to the second phase shifter.

[0059] See also Figure 3 , Figure 3 A schematic diagram of a base station system provided in an embodiment of the present application. Figure 3 In one example shown, the base station receives a first signal sent by a signal source through a radio frequency channel. The destination antenna array of the first signal is the antenna array corresponding to the phase shifter with dynamically adjusted phase. The base station sends the first signal processed by the power bridge to the phase shifter with fixed phase. Specifically, the base station converges the power of the first signal passing through the power bridge to the radio frequency channel where the phase shifter with fixed phase is located by designing the baseband weights and bridge parameters, and makes the power of the first signal in the radio frequency channel of the phase shifter with dynamically adjusted phase be zero. The first signal can be a radio frequency signal of a common channel or a radio frequency signal of a service channel. The baseband weights of the common channel and the service channel can be the same or different. For example, Figure 3 The baseband weights of the common channel are W0, W1, ..., W n-2 、W n-1 , the baseband weights of the traffic channel are W′0, W′1, …, W′ n-2 , W′ n-1 .

[0060] 203. The base station receives a second signal from the radio frequency channel, and the destination antenna array of the second signal is the antenna array corresponding to the second phase shifter.

[0061] The base station receives a second signal from the RF channel. The destination antenna array of the second signal is the antenna array corresponding to the second phase shifter. For the second signal whose destination antenna array is the antenna array of the second phase shifter, after passing through the power bridge, the second signal is still sent to the antenna array corresponding to the second phase shifter through the RF channel connected to the second phase shifter.

[0062] See also Figure 3 , Figure 3 A schematic diagram of a base station system provided in an embodiment of the present application. Figure 3 In an example shown, the base station receives a signal sent by a signal source through a radio frequency channel. The signal is sent to antenna arrays corresponding to different phase shifters through a baseband module and a power bridge. The signal includes a first signal and a second signal, wherein the destination antenna array of the first signal is the antenna array corresponding to the phase shifter with dynamically adjusted phase, and the destination antenna array of the second signal is the antenna array corresponding to the phase shifter with fixed phase.

[0063] 204. The base station superimposes the first signal on the second signal through a power bridge.

[0064] The base station superimposes the first signal on the second signal through a power bridge. Specifically, the base station superimposes the first signal on the second signal based on the baseband weight and the bridge parameters of the power bridge. For the first signal of the antenna array whose destination antenna array is the antenna array corresponding to the first phase shifter, after processing by the power bridge, the first signal is converged to the antenna array corresponding to the second phase shifter, and is superimposed and sent with the second signal of the antenna array whose destination antenna array is the antenna array corresponding to the second phase shifter, that is, the signal power received by the antenna array corresponding to the second phase shifter is doubled, and the antenna array corresponding to the first phase shifter does not send the first signal.

[0065] The following combination Figure 4 For an introduction to the signal processing method provided in the embodiment of the present application, please refer to Figure 4 , Figure 4 A schematic diagram of power variation of a signal processing method provided in an embodiment of the present application. Figure 4 In one example shown, the base station sends the first signal processed by the power bridge to the second phase shifter, so that the power of the first signal and the second signal are superimposed.

[0066] like Figure 4 As shown, RF channel TX0 to RF channel TX n The signal power on the RF channel TX0 and the RF channel TX n The connected phase shifter is a fixed phase shifter, RF channel TX0 and RF channel TX n The signal on the first signal, RF channel TX1 and RF channel TX n-1The connected phase shifter is a phase shifter with dynamic phase adjustment, RF channel TX1 and RF channel TX n-1 The signal on is the second signal. After being processed by the power bridge, the signal of RF channel TX1 is converged to RF channel TX0, and the signal of RF channel TX n-1 The signal is converged to the RF channel TX n , that is, the base station superimposes the first signal on the second signal through the power bridge, and the superimposed RF channel TX0 and RF channel TX n The signal power on RF channel TX1 and RF channel TX is 2*x. n-1 The signal power on is 0.

[0067] See also Figure 5 , Figure 5 Schematic diagram of a base station processing a signal of a radio frequency channel based on baseband weights and bridge parameters in an embodiment of the present application. Figure 5 As shown, (a) is a schematic diagram of signal processing of the common channel, and (b) is a schematic diagram of signal processing of the service channel. In the embodiment shown in (a), it is assumed that the signals on the common channel TX0 and the common channel TX1 are both S0, and the common channel TX n-1 and common channel TX n The signals on the n-2 , where common channels TX0 and TX n Connect the fixed phase shifter, common channel TX1 and common channel TX n-1 Connect the phase shifter with dynamically adjustable phase, after the power bridge processing, the common channel TX0 and the common channel TX n The signal is 2*S0, common channel TX1 and common channel TX n-1 The signal is 0.

[0068] In the example shown in Figure (b), it is assumed that the signal on the traffic channel TX0 is (S0-j*S1) / 2, the signal on the traffic channel TX1 is (S0+j*S1) / 2, and the traffic channel TX n-1 The signals on the n-1 +j*S n-2 ) / 2, traffic channel TX n The signal is (S n-1 -j*S n-2 ) / 2, where traffic channels TX0 and TX n Connect the fixed phase shifter, business channel TX1 and business channel TX n-1 Connect the phase shifter with dynamically adjustable phase. After the power bridge is processed, the signal of the business channel TX0 is S0, the signal of the business channel TX1 is S1, and the signal of the business channel TX n-1 The signal is S n-2 , service channel TXn The signal is S n-1 .

[0069] See also Figure 6 , Figure 6 This is a comparative diagram of beam coverage provided in the embodiment of the present application. Figure 6 As shown in the figure, (a) is a schematic diagram of the power of different RF channels and the beam coverage range before the introduction of the power bridge. Although the signal is sent through the phase shifter with a fixed phase in the RF channel, the power of the signal is not superimposed on the RF channel where the phase shifter with a fixed phase is located, causing the signal power to decrease and the beam coverage to shrink.

[0070] like Figure 6 As shown, Figure (b) is a schematic diagram of the power of different RF channels and the beam coverage range after the introduction of the power bridge. After being processed by the power bridge, the signal is sent through the phase shifter with a fixed phase in the RF channel. The power of the signal originally going to the phase shifter with dynamically adjusted phase is superimposed with the power of the signal originally going to the phase shifter with a fixed phase, so that the power of the transmitted signal does not decrease and the coverage range of the beam does not shrink.

[0071] In one Figure 6 In an example shown, taking the transmission of SSB on the NR common channel as an example, if SSB is transmitted on all RF channels, the shape of the SSB transmission beam changes dynamically with the phase of the phase shifter, and the synchronization signal and broadcast signal of the NR cell fluctuate greatly. Therefore, the access success rate of users in the NR cell, especially the users at the edge of the cell, decreases. In order to solve the above problem, the SSB of the NR common channel is only transmitted on the RF channel with a fixed phase shifter phase. Although the transmission beam of the NR SSB is fixed, the number of transmission channels is reduced by half, and the total transmission power is reduced by half, so the coverage range of the NR cell will shrink.

[0072] In the embodiment of the present application, the SSB of the NR common channel is also transmitted on all RF channels. The total transmission power of the SSB of the NR common channel is the same, but the SSB is converged to the antenna array with a fixed phase of the phase shifter after passing through the power bridge for transmission. Therefore, the transmission beam is stable, thereby improving the access success rate of cell users. Since the SSB in the embodiment of the present application is transmitted on all RF channels, compared with the solution in which the SSB is only transmitted on the RF channel with a fixed phase shifter phase, the number of SSB transmission RF channels is doubled, that is, the total transmission power of the SSB is doubled, thereby improving the cell coverage.

[0076] The processing unit 702 is configured to send the first signal processed by the power bridge to the second phase shifter.

[0077] Based on the second aspect, in one possible implementation, the interface unit 701 is further configured to receive a second signal from a radio frequency channel, where the destination antenna array of the second channel is the antenna array corresponding to the second phase shifter;
