This application claims priority to Chinese Patent Application No. 202311864442.6, filed on Dec. 29, 2023, and the entire content of which is incorporated herein by reference.
The present disclosure relates to the technical field of wireless communications, and more particularly, to a phase compensation method, apparatus, device, and storage medium.
The maximum bandwidth supported by 5G base stations is 100 M. Because terminals do not necessarily require such a large bandwidth, some bandwidth (bandwidth par or BWP) is divided. In the process of similar communication between terminals using BWP, a problem may occur when a center frequency f1 of a base station is inconsistent with a center frequency f0 of a terminal BWP, resulting in a larger phase deviation of symbols received by the base station. Phase compensation is required when the 5G base station receives a terminal signal for processing and when the terminal receives a downlink signal of the 5G base station. However, for a physical random access channel (PRACH), due to the shift property of fast Fourier transform (FFT), a constant fixed phase will be retained in the time-frequency domain, and power delay profile (PDP) detection will not be affected by an additional fixed phase. Therefore, PRACH does not require additional phase compensation.
Open RAN refers to that base stations can be built through open source software, open interfaces, and white box hardware, thereby reducing industry costs. To facilitate the white box hardware, the main BBU of the base station should run on a general server to facilitate software and hardware decoupling.
To implement different phase compensation strategies for different channels in the prior art, the time domain data received by an RRU Hub under the Open RAN architecture is subject to cyclic prefix (CP) removal, and the spectrum is moved, such that the spectrum of the baseband signal is moved to the spectrum centered on direct current (DC), and then down-sampling and low-pass filtering are performed in the time domain. FFT is used to extract the time and frequency domain information of PRACH separately. For the time domain data of other channels, the RRU Hub directly uses FFT to convert it into frequency domain information, and then performs phase compensation in the frequency domain. As such, except for PRACH, other uplink channels are phase compensated. Because the implementation of phase compensation requires substantial computing power of the field programmable gate array (FPGA) in the RRU HUB, it places a substantial dependency on the FPGA. Therefore, simplifying the functions of general-purpose hardware FPGA and reducing the dependency on the FPGA become an urgent problem to solve.
One aspect of the present disclosure provides a phase compensation method. The phase compensation method includes: converting, by a radio frequency (RF) remote unit hub, time domain data received from an RF remote unit into frequency domain data; and performing, by a baseband processing unit, resource de-mapping on the frequency domain data to obtain a first time-frequency resource with phase compensation completed and a second time-frequency resource without phase compensation. The first time-frequency resource corresponds to a first channel and the second time-frequency resource corresponds to a second channel.
Another aspect of the present disclosure provides a phase compensation apparatus. The phase compensation apparatus includes: a radio frequency (RF) remote unit hub configured to convert time domain data received from an RF remote unit into frequency domain data; and a baseband processing unit configured to perform resource de-mapping on the frequency domain data to obtain a first time-frequency resource that has completed phase compensation and a second time-frequency resource without the phase compensation. The first time-frequency resource corresponds to a first channel and the second time-frequency resource corresponds to a second channel.
Another aspect of the present disclosure provides a computer-readable storage medium storing a computer program. When being executed by a processor, the computer program causes the processor to: convert, by a radio frequency (RF) remote unit hub, time domain data received from an RF remote unit into frequency domain data; and perform, by a baseband processing unit, resource de-mapping on the frequency domain data to obtain a first time-frequency resource with phase compensation completed and a second time-frequency resource without phase compensation. The first time-frequency resource corresponds to a first channel and the second time-frequency resource corresponds to a second channel.

Before further describing the embodiments of the present disclosure in detail, the terms involved in the embodiments of the present disclosure are described. The terms involved in the embodiments of the present disclosure are applicable to the following definitions.
ORAN (Open RAN) refers to building base stations through open source software, open interfaces, and white box hardware, thereby reducing industry costs. To facilitate white box hardware, the main body of the base station must run on a general-purpose server to facilitate software and hardware decoupling.
Currently, the main body of Open RAN includes key modules such as base band unit (BBU), remote radio unit (RRU), and RRU Hub. The BBU includes distributed units (DU) and a centralized unit (CU).
Field programmable gate array (FPGA) is a semi-custom circuit in application-specific integrated circuits. It is a programmable logic array that can effectively solve the problem of the small number of gate circuits of the original device.
Physical random access channel (PRACH) is an access channel when the terminal initiates a call. After receiving a PRACH response message, the terminal will send a radio resource control (RRC) connection request message on the PRACH channel according to the information indicated by the base station to establish an RRC connection.
Physical uplink shared channel (PUSCH) is used to carry data from a transmission channel.
Physical uplink control channel (PUCCH) is used to transmit control information between the terminal and the base station.
Sounding reference signal (SRS) is a reference signal sent by the terminal for the base station to measure and evaluate the uplink channel propagation quality.
The present disclosure provides a phase compensation method.
At S110, a radio frequency (RF) remote unit hub converts time domain data received from an RF remote unit into frequency domain data.
Here, the RF remote unit hub (RRU HUB) may be connected to the RF remote unit (RRU) through a common public radio interface (CPRI) or an enhanced CPRI (eCPRI) to receive the time domain data sent by the RRU. CPRI is based on circuit switching time division multiplexing (TDM), while eCPRI is based on packet switching. Thus, CPRI naturally carries synchronization information, while eCPRI needs to be synchronized through clock synchronization, for example, through precision time protocol (PTP) and synchronous Ethernet (SyncE) technology.
The frequency domain data includes data of PUSCH, PUCCH, SRS and PRACH channels.
For example, a 4096-point FFT uplink or inverse FFT (IFFT) downlink with a bandwidth of 100 M may be implemented on the RRU Hub without distinguishing channels. Then, resource de-mapping of each channel is uniformly implemented in the BBU, and the PRACH, PUSCH, PUCCH and SRS channels are uniformly processed in the BBU.
At S120, the baseband processing unit performs the resource de-mapping on the frequency domain data to obtain a first time-frequency resource with phase compensation and a second time-frequency resource without phase compensation, where the first time-frequency resource corresponds to a first channel, and the second time-frequency resource corresponds to a second channel.
In some embodiments, the first channel includes at least one of the following: a physical uplink shared channel, a physical uplink control channel, and a channel sounding reference signal. The second channel is a physical random access channel.
Here, for the physical random access channel (PRACH), due to the shift property of FFT, a constant fixed phase may be retained in the time-frequency domain, and power delay profile (PDP) detection may not be affected by an additional fixed phase, so no additional phase compensation is required. Therefore, the second time-frequency resource does not need to be phase compensated.
According to the provisions of protocol 38.211, the physical uplink shared channel, physical uplink control channel, and the channel sounding reference signal need to be phase compensated.
During the implementation process, the baseband processing unit performs the resource de-mapping on the frequency domain data to obtain the first time-frequency resource with phase compensation and the second time-frequency resource without phase compensation to satisfy the protocol provisions.
In the embodiment of the present disclosure, the RF remote unit hub first converts the time domain data received from the RF remote unit into frequency domain data. Then the baseband processing unit performs the resource de-mapping on the frequency domain data to obtain the first time-frequency resource with phase compensation and the second time-frequency resource without phase compensation. The first time-frequency resource corresponds to the first channel and the second time-frequency resource corresponds to the second channel. As such, the conversion of the time domain data and the frequency domain data may be achieved on the RRU Hub without distinguishing channels. The resource de-mapping of each channel is uniformly achieved on the BBU. The PRACH, PUSCH, PUCCH and SRS channels are uniformly processed on the BBU. Releasing part of the computing power of the RF remote unit hub to the baseband processing unit effectively reduces the FPGA computing power and capacity requirements of the RF remote unit hub.
At S210, the radio frequency remote unit hub performs phase compensation on the frequency domain data to obtain the frequency domain data with phase compensation.
The frequency domain data includes data of PUSCH, PUCCH, SRS and PRACH channels.
In the process, the RRU HUB converts the received time domain data into the frequency domain data using FFT. Then the phase compensation function may be implemented on the RRU Hub using FPGA logic.
For example, a 4096-point FFT uplink or IFFT downlink with a bandwidth of 100 M may be implemented on the RRU Hub without distinguishing channels. Then, the phase compensation of each channel is uniformly performed on the RRU Hub to obtain the frequency domain data of the PUSCH, PUCCH, SRS and PRACH channels with phase compensation.
At S220, the baseband processing unit performs the resource de-mapping on the frequency domain data that has completed phase compensation, and obtains the first time-frequency resource that has completed phase compensation, and a third time-frequency resource corresponding to the second channel that has completed phase compensation.
Here, the first time-frequency resource corresponds to the first channel, and the data of the first channel is data that needs phase compensation. The third time-frequency resource corresponds to the second channel, and the data of the second channel is data that does not need phase compensation.
In the process, the BBU performs the resource de-mapping on the frequency domain data to obtain the first time-frequency resource that has completed phase compensation in the RRU Hub and the third time-frequency resource corresponding to the second channel that has completed phase compensation.
At S230, the baseband processing unit performs reverse phase compensation based on the third time-frequency resource to obtain the second time-frequency resource.
Here, because the third time-frequency resource corresponds to the second channel, the data of the second channel is data that does not need phase compensation. Therefore, the BBU may perform the reverse phase compensation on the third time-frequency resource to obtain the second time-frequency resource. Because the second time-frequency resource is a resource that has completed the reverse phase compensation, it satisfies the protocol requirements (i.e., the protocol provisions).
For example, the PRACH channel on the BBU may use software to implement the corresponding reverse phase compensation, thereby satisfying the protocol requirements that the PRACH does not require phase compensation.
In the embodiments of the present disclosure, the RF remote unit hub performs phase compensation on the frequency domain data to obtain the frequency domain data with completed phase compensation. The baseband processing unit performs the resource de-mapping on the frequency domain data with completed phase compensation to obtain the first time-frequency resource with completed phase compensation and the third time-frequency resource corresponding to the second channel with completed phase compensation. The baseband processing unit performs the reverse phase compensation based on the third time-frequency resource to obtain the second time-frequency resource. As such, the computing power and capacity resources of the RRU HUB can be saved, and the first time-frequency resource and the second time-frequency resource that satisfy the protocol requirements can be obtained respectively.
In some embodiments, the process S230 “the baseband processing unit performs the reverse phase compensation based on the third time-frequency resource to obtain the second time-frequency resource” may be implemented by the following processes.
At S231, the baseband processing unit constructs second resource block information of the second channel based on the third time-frequency resource.
Here, the resource block (RB) is a unit of bandwidth occupied by a service resource in communication.
In some embodiments, the third time-frequency resource may correspond to time-frequency domain information mapped by PRACH. In the process, the BBU may construct resource block information of PRACH based on the time-frequency domain information mapped by PRACH.
At S232, the baseband processing unit performs the reverse phase compensation on the second resource block information to obtain the second time-frequency resource.
In the process, the BBU may perform the reverse phase compensation on the second resource block information (implemented by software), such that except for the third time-frequency resource, the remaining first time-frequency resources are all phase compensated for uplink.
For example, the BBU may perform the reverse phase compensation on the resource block information constructed by PRACH, such that except for PRACH, the other uplink channels (PUSCH, PUCCH, SRS) are all phase compensated for uplink.
In the embodiments of the present disclosure, the baseband processing unit constructs the second resource block information of the second channel based on the third time-frequency resource. The baseband processing unit performs the reverse phase compensation on the second resource block information to obtain the second time-frequency resource. As such, the reverse phase compensation of the third time-frequency resource can be achieved to obtain the second time-frequency resource that satisfies the protocol requirements.
In some embodiments, as shown in
At S310, the baseband processing unit performs the resource de-mapping on the frequency domain data to extract a fourth time-frequency resource corresponding to the first channel and a fifth time-frequency resource corresponding to the second channel.
Here, because the fourth time-frequency resource corresponding to the first channel needs to be phase compensated, and the fifth time-frequency resource corresponding to the second channel does not need to be phase compensated.
In the process, the BBU may first perform resource de-mapping on the time-frequency resources obtained from the RRU HUB to extract the fourth time-frequency resource corresponding to the first channel and the fifth time-frequency resource corresponding to the second channel.
At S320, the baseband processing unit performs the phase compensation on the fourth time-frequency resource to obtain the first time-frequency resource.
Here, the fourth time-frequency resource needs to be phase compensated.
In the process, the BBU only performs the phase compensation on the fourth time-frequency resource to obtain the first time-frequency resource. For example, the phase compensation may be performed by extracting three channels, PUSCH, PUCCH, and SRS after the BBU performs the resource de-mapping, and then implementing phase compensation of the three channels, PUSCH, PUCCH, and SRS in software mode. While the PRACH channel extracted separately after the BBU performs the resource de-mapping does not need phase compensation, thereby satisfying the protocol requirements.
At S330, the baseband processing unit constructs the second time-frequency resource of the second channel based on the fifth time-frequency resource.
In the process, because the fifth time-frequency resource corresponds to the second channel, the second time-frequency resource of the second channel may be constructed based on the fifth time-frequency resource.
In the embodiments of the present disclosure, the baseband processing unit performs the resource de-mapping on the frequency domain data to extract the fourth time-frequency resource corresponding to the first channel and the fifth time-frequency resource corresponding to the second channel. The baseband processing unit performs the phase compensation on the fourth time-frequency resource to obtain the first time-frequency resource. Then, the baseband processing unit constructs the second time-frequency resource of the second channel based on the fifth time-frequency resource. As such, by de-mapping resources at the BBU and performing the phase compensation according to the protocol requirements, the computing power and capacity of the RRU HUB may be more effectively released, and the time-frequency resources that satisfy the protocol requirements may be obtained.
In some embodiments, the process S120 “the RF remote unit hub converts the time domain data received from the RF remote unit into the frequency domain data” may be implemented by the following processes.
At S121, the RF remote unit hub removes symbol prefix of the time domain data to obtain the time domain data with the symbol prefix removed.
In the process, the RRU HUB removes cyclic prefix (CP) of the received time domain data. CP refers to a symbol prefix, which is repeated at the end of the orthogonal frequency division multiplexing (OFDM) technology in the wireless system, and the receiving end is often configured to discard the cyclic prefix samples.
At 122, the RF remote unit hub performs a fast Fourier transform on the time domain data with the symbol prefix removed to obtain the frequency domain data.
Here, FFT is a method for Fourier transform analysis of time domain and frequency domain transformation.
In the process, the RRU HUB may use the fast Fourier transform (FFT) to convert the time domain data after symbol prefix removal into frequency domain data.
For example, the RRU Hub may perform low-level physical layer (Low PHY) processing including CP removal and FFT in a unified format. The Low PHY processing may be implemented using FPGA. In the embodiments of the present disclosure, the RF remote unit hub removes the symbol prefix of the time domain data to obtain the time domain data after the symbol prefix removal. Then, the RF remote unit hub performs the fast Fourier transform on the time domain data after the symbol prefix removal to obtain the frequency domain data. As such, the conversion of the time domain data into the frequency domain data may be implemented in the RRU HUB.
In some embodiments, a universal public radio interface is set on the RF remote unit hub such that the RF remote unit hub is connected to the RF remote unit through the universal public radio interface. An enhanced universal public radio interface is configured on the baseband processing unit such that the baseband processing unit is connected to the RF remote unit hub through the enhanced universal public radio interface.
Here, the interfaces connecting RRU, RRU Hub and BBU are common public radio interface (CPRI) and enhanced common public radio interface (eCPRI). CPRI is based on circuit switching (TDM), while eCPRI is based on packet switching. As such, CPRI naturally carries the synchronization information, while eCPRI needs to be synchronized through the clock synchronization (i.e., PTP) and synchronous Ethernet (i.e., SyncE) technology.
CPRI RRU does not involve Low PHY calculations and has a relatively low cost. Thus, CPRI may be selected as the interface between RRU and RRU Hub. The RRU Hub needs to implement some Low PHY functions. Because the frequency domain data is transmitted between RRU Hub and BBU, eCPRI based on Ethernet switching technology is selected. As such, ordinary network cards of the BBU may implement eCPRI, thereby reducing the cost of the entire base station.
The present disclosure also provides another phase compensation method.
At S401, the RRU Hub removes the CP from the CPRI time domain data received from the RRU to obtain the time domain data with the CP removed. In some embodiments, multiple RRUs and RRU Hubs may be connected using the CPRI, and the RRU Hubs may be connected to the BBU using the eCPRI interface. As such, the present disclosure can be compatible with more models of the RRUs.
In some embodiments, the multiple RRUs and RRU Hubs may be connected using the eCPRI, and the RRU Hubs may be connected to the BBU using the eCPRI interface. As such, part of the calculation of the RRU Hub may be transferred to the RRU for completion, thereby simplifying the function of the RRU Hub.
At S402, the RRU Hub performs the FFT conversion on the time domain data after the CP removal to obtain the frequency domain data.
At S403, the RRU Hub performs the phase compensation on the frequency domain data to obtain the frequency domain data after the phase compensation.
In some embodiments, the processes S402 and S403 are executed, and the CPRI interface, the FFT/IFFT, the CP removal, and the phase compensation functions are implemented on the RRU Hub without distinguishing channels. The BBU then performs the resource de-mapping to distinguish channels and performs different processing corresponding to different channels.
In the process, it can be determined whether the phase compensation is to be implemented using the FPGA of the RRU Hub according to the capacity of the FPGA on the RRU Hub. If the FPGA capacity on the RRU Hub is sufficiently large, the flowchart shown in
At S404, the BBU performs the resource de-mapping based on the received frequency domain data with the phase compensation sent by the RRU Hub and the time-frequency domain information mapped by PRACH, and obtains two types of data. A first type of data includes PUSH, PUCCH and SRS data, and a second type of data includes PRACH data.
At S405, the PUSH, PUCCH and SRS data are processed.
At S406, RB information of PRACH is constructed.
At S407, the reverse phase compensation is performed on the RB information of PRACH.
After the resource de-mapping, the reverse phase compensation is performed on the constructed RB information of PRACH. As such, the reverse phase compensation can be performed on the RB information of PRACH separately to satisfy the protocol requirements.
At S408, the PRACH data with the reverse phase compensation completed is processed.
In the process, processing the PRACH data that has completed the reverse phase compensation includes: correlating the PRACH data that has completed the reverse phase compensation with local preamble sequence frequency domain, performing 1024-point IFFT to obtain the time domain data, determining a maximum value of a correlation peak based on the time domain data, and determining timing advance (TA) using the preamble based on the determined result of the maximum value of the correlation peak.
In the embodiments of the present disclosure, a 4096-point FFT (uplink) or IFFT (downlink) with a bandwidth of 100 M is implemented on the RRU Hub, without distinguishing channels. The resource mapping of each channel is uniformly implemented on the BBU, and the PRACH, PUSCH, PUCCH and SRS channels are uniformly processed on the BBU. The phase compensation module is implemented on the RRU Hub using FPGA logic, such that the PRACH channel on the corresponding BBU may have the corresponding reverse phase compensation implementation in software. Thus, the protocol requirements that the PRACH does not require phase compensation are satisfied.
The present disclosure provides another phase compensation method.
At S411, the RRU Hub removes the CP from the CPRI time domain data received from the RRU to obtain the time domain data with the CP removed.
At S412, the RRU Hub performs the FFT conversion on the time domain data with the CP removed to obtain the frequency domain data.
At S413, the BBU performs the resource de-mapping on the frequency domain data received from the RRU Hub to obtain two types of data. A first type of data includes PUSH, PUCCH and SRS data, and a second type of data includes PRACH data.
At S414, the phase compensation is performed on the PUSH, PUCCH and SRS data to obtain the PUSH, PUCCH and SRS data with the phase compensation.
The phase compensation is performed on the PUSH, PUCCH and SRS data after the resource de-mapping, such that the phase compensation can be performed on the PUSCH, PUCCH and SRS channels separately.
At S415, the PUSH, PUCCH and SRS data with the phase compensation are processed.
At S416, the RB information of PRACH is constructed.
At S417, the RB information of PRACH is processed.
In the process, constructing the RB information of PRACH includes: correlating the constructed RB information of PRACH with the frequency domain of the local preamble sequence, performing 1024-point IFFT to obtain the time domain data, determining a maximum value of a correlation peak based on the time domain data, and determining the timing advance (TA) using the preamble based on the determined result of the maximum value of the correlation peak.
In the embodiments of the present disclosure, the 4096-point FFT (uplink) or IFFT (downlink) with a bandwidth of 100 M is implemented on the RRU Hub, without distinguishing channels. The resource mapping of each channel is uniformly implemented in the BBU, and the PRACH, PUSCH, PUCCH and SRS channels are uniformly processed in the BBU. The phase compensation may be implemented separately in the BBU after the resource mapping, and the three channels of PUSCH, PUCCH and SRS are extracted separately and implemented in software, and the PRACH channel does not need phase compensation, thereby satisfying the protocol requirements.
Based on the foregoing embodiments, the present disclosure also provides a phase compensation apparatus. The phase compensation apparatus includes the RF remote unit hub and the baseband processing unit. The RF remote unit hub and the baseband processing unit respectively include functional modules, which may be implemented by a processor in an electronic device, or may also be implemented by a specific logic circuit. In the process, the processor may be a central processing unit (CPU), a microprocessor (MPU), a digital signal processor (DSP), or a field programmable gate array (FPGA), etc.
