The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
[0054] Additionally, the terms "system" and "network" are often used interchangeably herein.
[0055] In the embodiments provided by the present invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.
[0056] For ease of understanding, some contents involved in the embodiments of the present invention are described below:
[0057] like Figure 1 and Figure 2 As shown, a baseband power sharing method according to an embodiment of the present invention is applied to a network device and includes the following steps.
[0058] S10, obtaining duplicate data corresponding to first data in a first baseband and second data in at least one second baseband;
[0059] It should be noted that the first baseband may be any one of all basebands on the pole arranged at the same position, and the second baseband may be a baseband on the pole other than the first baseband. The copied data is obtained by copying the second data, that is, the copied data contains the same content as the second data.
[0060] S20, acquiring third data according to the first data and the copied data;
[0061] It should be noted here that, through this step, the third data including all baseband data can be obtained.
[0062] S30, sending the third data to a first radio frequency module corresponding to the first baseband;
[0063] It should be noted that, through the above method, the first radio frequency module can simultaneously send data of all basebands on the pole.
[0064] In this embodiment, the first data in the first baseband and the copied data corresponding to the second data in the second baseband on the pole located at the same position are processed to obtain the third data, and the third data is sent to the first RF module corresponding to the first baseband. The data of the two basebands are sent through one RF module, thereby realizing power sharing of data on different basebands, making greater use of baseband power resources, improving the channel gain of the physical downlink shared channel, and improving the cell edge coverage capability. Application to the pole next to the high-speed railway can improve the user perception at the edge of the high-speed railway.
[0065] Optionally, the network device can be understood as a base station, a signal transmission device, etc. arranged on a pole.
[0066] It should be noted that the embodiment of the present invention only takes the transmission of the RF module corresponding to a baseband in the network device as an example. In the specific implementation, the corresponding operation needs to be performed for each baseband set on the pole. That is to say, the data obtained by the RF module corresponding to each baseband should be determined by the data of this baseband and the duplicate data of other basebands. For example, there are baseband 1, baseband 2 and baseband 3 as examples. The data received by the RF module corresponding to baseband 1 is determined by the first data in baseband 1, the duplicate data corresponding to the second data in baseband 2, and the duplicate data corresponding to the second data in baseband 3; the data received by the RF module corresponding to baseband 2 is determined by the first data in baseband 2, the duplicate data corresponding to the second data in baseband 1, and the duplicate data corresponding to the second data in baseband 3; the data received by the RF module corresponding to baseband 3 is determined by the first data in baseband 3, the duplicate data corresponding to the second data in baseband 1, and the duplicate data corresponding to the second data in baseband 2. For example, Figure 2 The power sharing process of the first baseband (baseband-1) and the second baseband (baseband-2) is shown in the figure. First, two new data with both the first data and the second data are obtained after processing in the baseband unit BBU, and are sent by the first baseband and the second baseband to the first RF module (RF module-1) and the second RF module (RF module-2) in the corresponding RF unit RRU respectively. When there are two basebands on the pole at the same position, the data content output to the RF modules corresponding to the two basebands includes the data content of the two basebands.
[0067] In the method provided by the embodiment of the present invention, the first data and / or the second data include: data in a data channel and / or a demodulation reference signal.
[0068] like Figure 3As shown, in this embodiment, the first data and / or the second data may include data in PDSCH (Physical Downlink Shared Channel) and / or demodulation reference signal DMRS (Demodulation Reference Signal), that is, the copying of the second data mentioned in the embodiment of the present invention refers to copying the data channel PDSCH and demodulation reference signal DMRS related to user service processing. The copied data is prepared for subsequent phase shifting and calibration addition.
[0069] It should be noted that the baseband signal is first replicated to copy the signals of N channels into 2N channels. The first data and / or the second data mentioned in this embodiment include not only PDSCH and DMRS, but also synchronization signals and control channels. Among them, considering the spacing between stations covered by high-speed rail, the synchronization signal SSB (Synchronization SignalBlock), including the primary synchronization signal PSS (Primary Synchronization Signal), the secondary synchronization signal SSS (Secondary Synchronization Signal), the broadcast signal PBCH (Physical Broadcast Channel) and the control channel PDCCH (Physical Downlink Control Channel) are not replicated.
[0070] In the method provided in the embodiment of the present invention, the above step S20 may include:
[0071] Step S21, performing phase shift processing on the first data and the copied data;
[0072] In this embodiment, since the original data and the replicated data undergo phase and amplitude changes, the baseband signal power is normalized and the original data is normalized. Processing, the copied data Processing, that is, performing phase shift processing on the first data and the copied data, thus completing the calculation of the phase amplitude.
[0073] Step S22, performing calibration transformation processing on the first data and the replicated data after the phase shift processing;
[0074] It should be noted that the calibration transformation can ensure that the power of the third data obtained by adding the first data and the copied data does not exceed the original total output power of the network device, thereby avoiding signal oversaturation overflow and ensuring that the third data can be accurately acquired subsequently.
[0075] Step S23, obtaining third data according to the first data and the copied data after the calibration transformation process.
[0076] Optionally, this step may generally be performed by adding the first data after the calibration transformation process and the copied data to obtain the third data.
[0077] In the method provided in the embodiment of the present invention, the step of performing calibration transformation on the first data and the replicated data after the phase shifting process comprises at least one of the following:
[0078] A11. The baseband bandwidth occupied by the first data remains unchanged, and a portion of the baseband bandwidth in the first baseband except the baseband bandwidth occupied by the first data is allocated to the duplicate data;
[0079] It should be noted that this method can be understood as using the same frequency domain resource power calibration. For example, for a pole equipped with baseband 1 and baseband 2, the baseband bandwidth occupied by the first data of baseband 1 remains unchanged, and the remaining bandwidth in baseband 1 is allocated to the copy data of the second data of baseband 2. If the bandwidth required for the copy data of the second data is greater than the remaining bandwidth in baseband 1, the bandwidth of the copy data of the second data is reduced; the baseband bandwidth occupied by the first data of baseband 2 remains unchanged, and the remaining bandwidth in baseband 2 is allocated to the copy data of the second data of baseband 1. If the bandwidth required for the copy data of the second data is greater than the remaining bandwidth in baseband 2, the bandwidth of the copy data of the second data is reduced. The two baseband resources share power resources according to the corresponding PRB (Physical Resource Block) positions. If the corresponding PRB resources are idle, the idle PRB power resources can be shared with the corresponding non-idle PRB, and the energy is doubled; if the corresponding PRB resources are occupied, power resources are not shared, and the energy remains unchanged; if the corresponding PRBs are not occupied, the PRB power resources are not used.
[0080] A12. The baseband bandwidth occupied by the first data remains unchanged, the baseband bandwidth portion of the first baseband except that occupied by the first data is allocated to the copied data, and the energy of the first baseband except that occupied by the first data is evenly allocated to the first data and the copied data.
[0081] It should be noted that this method can be understood as adopting cell-level power calibration. For example, for a pole equipped with baseband 1 and baseband 2, the baseband bandwidth occupied by the first data of baseband 1 remains unchanged, and the remaining bandwidth in baseband 1 is allocated to the copy data of the second data of baseband 2. If the bandwidth required for the copy data of the second data is greater than the remaining bandwidth in baseband 1, the bandwidth of the copy data of the second data is reduced, and the energy not occupied by the first data of baseband 1 is evenly distributed to the copy data of the first data of baseband 1 and the second data of baseband 2; the baseband bandwidth occupied by the first data of baseband 2 remains unchanged, and the remaining bandwidth in baseband 2 is allocated to the copy data of the second data of baseband 1. If the bandwidth required for the copy data of the second data is greater than the remaining bandwidth in baseband 2, the bandwidth of the copy data of the second data is reduced, and the energy not occupied by the first data of baseband 2 is evenly distributed to the copy data of the first data of baseband 2 and the second data of baseband 1. These two baseband resources evenly distribute the power of the frequency domain resources not occupied by the auxiliary cell to the frequency domain resources occupied by the target cell, so as to achieve the effect of maximizing power utilization. Taking 100M bandwidth and 273 PRBs as an example, assuming that the power resource of each PRB is 1, the power resource occupied by the first baseband is M, and the power occupied by the second baseband is N. After cell-level power sharing, the power resource of each PRB in the first baseband becomes 1+(100-N) / M, and the power resource of each PRB in the first baseband becomes 1+(100-M) / N, which effectively improves user throughput.
[0082] In real life, the calibration method for the baseband power sharing process on high-speed rail is divided into two application scenarios: without passing the pole and passing the pole. Figure 5 As shown in the figure, in case 1, the vehicle body has not passed the pole and the rear of the vehicle has passed the pole, which is a case of not passing the pole. In case 2, the vehicle body crosses the pole, which is a case of passing the pole. In case 1, only one of the two TRPs (Transmission and Receiving Point) on the same pole has users. High-speed rail users are all on baseband 1, and only some public network users are on baseband 2. Energy sharing can take effect, and the continuous distance is equal to the station spacing. In case 2, both TRPs on the same pole have users, and energy sharing occurs according to the probability of the service scheduling of the two TRPs. The continuous distance is equal to the vehicle length. At this time, both TRPs have high-speed rail users. Figure 6 and Figure 7 Two power calibration methods corresponding to the same frequency domain resources and cell level are shown for the cases of not passing the pole and passing the pole respectively. The horizontal size of the graph represents the time-frequency bandwidth, and the vertical size represents the power energy.
[0083] In the method provided in the embodiment of the present invention, the acquiring the duplicate data corresponding to the second data in the second baseband may include:
[0084] The duplicate data is acquired before or during the second data processing.
[0085] In this embodiment, there are multiple options for the starting point of copying the second data. The data can be copied at the beginning of baseband parsing, or at a certain node in the baseband implementation process, that is, the copied data is obtained before or during the second data processing. Figure 4 As shown, the baseband implementation process has multiple nodes: scrambling, modulation, layer mapping, precoding, resource mapping and IFFT (Inverse Fast Fourier Transform). When the first data and the second data start to be copied, they are phase shifted, calibrated and added to obtain initial third data, and then the initial third data is further processed according to the remaining nodes to obtain the third data.
[0086] The method provided in the embodiment of the present invention further includes:
[0087] S30, obtaining a first calibration coefficient, where the first calibration coefficient is obtained according to first calibration data sent by the first radio frequency module corresponding to the first baseband;
[0088] It should be noted that in order to ensure that the frequency domain amplitude of the transmission channel of multiple basebands on the pole at the same position is consistent with the frequency domain amplitude of the receiving channel of the RF module corresponding to the baseband after power sharing, multiple basebands and RF modules corresponding to the multiple basebands need to be jointly calibrated. The joint calibration first requires the RF module corresponding to the baseband to send calibration data to the baseband, and the baseband obtains the calibration coefficient according to the received calibration data. Step S30 is to obtain the first calibration coefficient of the first baseband.
[0089] S40, obtaining a second calibration coefficient, where the second calibration coefficient is obtained according to second calibration data sent by a second radio frequency module corresponding to at least one second baseband;
[0090] It should be noted that this step is to obtain the second calibration coefficient of the second baseband.
[0091] S50, obtaining a third calibration coefficient according to the first calibration coefficient and the second calibration coefficient;
[0092] It should be noted that the joint calibration module in any one of the multiple basebands on the pole at the same position calibrates and adjusts the first calibration coefficient corresponding to the first baseband, the second calibration coefficient corresponding to the second baseband, and the calibration coefficients corresponding to other basebands to form a new calibration sequence and information, that is, to obtain the third calibration coefficient.
[0093] S60, sending the third calibration coefficient to the first radio frequency module corresponding to the first baseband;
[0094] It should be noted that the description of this step is for the first baseband, and the third calibration coefficient is sent to the first RF module corresponding to the first baseband. In specific implementation, the third calibration coefficient obtained after calibration adjustment is sent to the RF modules corresponding to multiple basebands of joint calibration through the downlink.
[0095] In the method provided by the embodiment of the present invention, the above step S60 may include:
[0096] A61. Send the third calibration coefficient to the first baseband to obtain third calibration data;
[0097] It should be noted that the description of this step is for the first baseband, the third calibration coefficient is sent to the first baseband, and the first baseband obtains the third calibration data based on the third calibration coefficient. In specific implementation, the third calibration coefficient obtained after calibration adjustment is sent to the multiple basebands of joint calibration through the downlink, and each baseband obtains the third calibration data based on the third calibration coefficient to ensure the consistency of the frequency domain amplitude and phase of the transmitting channels of multiple basebands.
[0098] A62. Send the third calibration data to the first RF module.
[0099] It should be noted that the description of this step is for the first RF module corresponding to the first baseband, and the third calibration data is sent to the first RF module corresponding to the first baseband. In specific implementation, the third calibration data obtained by the multiple basebands jointly calibrated are sent to the corresponding RF modules respectively to ensure the consistency of the frequency domain amplitude and phase of the receiving channels of the RF modules corresponding to the multiple basebands.
[0100] It should be noted that there is weak coverage between high-speed rail sites. By sharing power resources between basebands, power convergence between left and right sectors is achieved, and the scheduling performance of the high-speed rail at a speed of 250km / h is met, which can effectively improve the throughput of users at far and near points and enhance user experience. The signals in the two basebands are mixed by the baseband power sharing method, so that the signals of the two basebands can be transmitted simultaneously on one path, and the two basebands have the ability to share power. The baseband unit downlink adds signal replication and phase shifting processing on the basis of the original physical layer implementation process, and through calibration transformation, it ensures that the total system power after baseband power sharing does not exceed the original total output power of the system, avoiding signal oversaturation overflow; it can enhance the communication connection strength of the system and improve data transmission efficiency; at the same time, through the joint calibration of the two RF modules, the consistency of the frequency domain amplitude and phase of each sending and receiving RF channel is guaranteed, so that data can be sent in alignment. Improved downlink edge coverage and improved user throughput.
