[0002] The base station can be configured with different antennas, each antenna can send a signal to the terminal based on a beam, the beams corresponding to different antennas have different beam directions, and each beam has a different coverage range. Before sending a signal to a terminal, the base station can add an SSB (Synchronization Signal and Physical Broadcast Channel block) in the signal corresponding to different beams, and send the above signal based on the beam. After obtaining the SSB in the signal, the terminal can determine the beam with the best communication effect for itself based on the SSB, and feed back the determination result to the base station, so that the base station can send a signal to the terminal based on the beam with the best communication effect.

[0003] However, if the terminal determines that the beam of the base station fails in the process of determining the beam with the best communication effect for itself, it can feed back a beam failure message to the base station, and the base station needs to recover the beam, i.e., select the beam and retransmit the beam.

[0089] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0090] To enable a base station to adaptively recover its beam, embodiments of the present invention provide a beam control method, a base station, a terminal, and an apparatus.

[0091] In one embodiment of the present invention, a beam control method is provided, applied to a first base station, the method comprising:

[0092] After determining that the beam of the first base station has failed, for each SSB, the position of the SSB in the target signal is assigned, wherein the target signal is the signal carrying the SSB to be transmitted by the first base station, and the assigned position includes the time domain position and frequency domain position of the SSB in the signal.

[0093] Based on communication information, the target beam corresponding to each target signal is determined, wherein the aforementioned communication information represents the communication status between the first base station and the terminals within its own cell service range;

[0094] For each target beam, determine the transmitting antenna on the first base station used to transmit the target beam, and the antenna configuration information of the transmitting antenna;

[0095] Each SSB is added to its assigned position in the corresponding target signal;

[0096] For each target beam, based on the antenna configuration information of the transmitting antenna corresponding to that target beam, the target beam carrying the corresponding target signal is transmitted through the aforementioned transmitting antenna.

[0097] As can be seen from the above, after the first base station determines that its beam has failed, it can reassign the positions of different SSBs in the target signal, allocate target beams to each target signal, and determine the transmitting antennas and their configuration information for transmitting each target beam. Finally, after adding the SSB to the target signal, the transmitting antenna transmits the target beam carrying the target signal according to the antenna configuration information, enabling the first base station to resend the SSB to the terminal, completing the beam retransmission process. Furthermore, this process does not require manual intervention, thus improving the efficiency of beam recovery.

[0098] See Figure 1 This is a flowchart illustrating the first beam control method provided in an embodiment of the present invention, which is applied to a first base station.

[0099] Specifically, the aforementioned first base station can be a base station that provides communication services to terminals based on MIMO (multiple-in multiple-out) technology. That is, the aforementioned first base station has multiple transmitting antennas and can transmit different beams through different transmitting antennas.

[0100] For example, the first base station mentioned above can be an LTE (Long Term Evolution) base station based on 4G technology. It can also be a Sub 6GHz NR (New Radio) base station based on 5G technology. The Sub 6GHz NR base station uses frequency bands below 6GHz to provide communication services to terminals, such as the 3.3–3.6GHz band, the 4.8–5.0GHz band, the 2.6GHz band, the 1.8GHz band, and the 2.1GHz band. Alternatively, it can be an mmWave NR (Millimeter wave New Radio) base station based on 5G technology. The mmWave NR base station uses millimeter waves to provide communication services to terminals, such as the millimeter wave frequency range of 24.75–27.5GHz and 37–42.5GHz. Furthermore, the first base station mentioned above can also be a base station based on other versions of communication technologies.

[0101] When the first base station is an mmWave NR base station, the first base station can use a hybrid digital and analog beamforming method for beamforming.

[0102] Specifically, the beam control method applied to the first base station can be implemented through the following steps S101-S105.

[0103] S101: After determining that the beam of the first base station has failed, assign the position of each SSB in the target signal.

[0104] The target signal is the signal carrying an SSB to be transmitted by the first base station. The allocated positions of the SSB include both the time-domain and frequency-domain positions within the signal. Each target signal contains one SSB, and the number of SSBs can be a preset value, such as 4, 8, 16, or 32.

[0105] Specifically, the beam failure of the first base station may be due to excessive channel noise, causing significant interference to the signal during transmission. It could also be due to obstructions in the beam propagation direction, affecting beam transmission. This is especially true when the first base station operates at a higher frequency, such as if it were an mmWave NR base station, where obstructions would have a greater impact on beam propagation.

[0106] In addition, the first base station can send SSB to the terminal through the beam. The terminal can determine the beam with the best communication quality for itself based on the received SSB. If the terminal determines that there is a faulty beam in the beam transmitted by the first base station during the process of determining the beam with the best communication quality for itself, it can send a beam fault message back to the first base station, so that the first base station can determine that its own beam has failed.

[0107] Specifically, the aforementioned terminal can directly report the beam fault message based on the link between itself and the first base station, enabling the first base station to determine that its beam has failed. Alternatively, the first base station can also determine that its beam has failed through step A below, which will not be detailed here.

[0108] In one embodiment of the present invention, the time domain position of the SSB in the signal can be represented by the time slot in which the SSB is located, and the frequency domain position of the SSB in the signal can be represented by the frequency band in which the SSB is located.

[0109] In addition, the above step S101 can be implemented by the MAC (Medium Access Control) in L2 of the BBU (Baseband Unit) in the first base station, where L2 is the data link layer.

[0110] Specifically, step S101 can be achieved through the following step B.

[0111] Step B: The MAC within the BBU of the first base station configures and assigns the position of each SSB in the target signal through the BBU backend.

[0112] S102: Based on communication information, determine the target beam corresponding to each target signal.

[0113] The aforementioned communication information indicates the communication status between the first base station and terminals within its service range.

[0114] Specifically, the aforementioned communication information can be information fed back to the first base station from terminals within its service range. Through this information, the first base station can determine which direction's terminals provide better communication, and thus designate the beam corresponding to that direction as the target beam. Since each target beam carries a target signal containing one SSB, the number of determined target beams is the same as the number of SSBs. The aforementioned communication information can include: data transmission rate, packet loss rate, and signal strength between the first base station and the terminals.

[0115] In one embodiment of the present invention, the first base station may record the correspondence between different communication information and target beams. Through the recorded correspondence, the first base station may determine the target beams corresponding to different communication information.

[0116] In addition, after determining the target beam corresponding to each target signal based on the above communication information, the beam index of the determined target beam can be recorded to indicate that the above beam is selected as the target beam.

[0117] In one embodiment of the present invention, step S102 can also be implemented by the MAC in the BBU.

[0118] Specifically, step S102 can be achieved through the following step C.

[0119] Step C: The MAC above determines the target beam corresponding to each target signal based on communication information.

[0120] S103: For each target beam, determine the transmitting antenna on the first base station used to transmit the target beam, and the antenna configuration information of the transmitting antenna.

[0121] In one embodiment of the present invention, for each target beam, a transmitting antenna whose direction is the aforementioned beam direction can be determined based on the beam direction of the target beam, and used as the transmitting antenna for transmitting the target beam.

[0122] Specifically, the different transmitting antennas on the first base station can be located on different panels (subarrays). Each panel contains multiple transmitting antennas. For each target beam, the panel where the transmitting antenna used to transmit the target beam is located can be determined first, and then the transmitting antenna used to transmit the target beam can be selected from the determined panel.

[0123] In addition, the antenna configuration information for each transmitting antenna can be: fixed antenna configuration information pre-set for that transmitting antenna.

[0124] The antenna configuration information mentioned above may include information such as amplitude and phase configuration values.

[0125] In another embodiment of the present invention, step S103 can be implemented by step D, which will not be described in detail here.

[0126] Furthermore, the above step S103 can be implemented using an FPGA (Field Programmable Gate Array) within the AAU (Active Antenna Unit) of the first base station.

[0127] If the above steps S101-S102 are implemented by the MAC in the BBU of the first base station, after the BBU determines the target beam corresponding to each SSB, it can send the beam index of the determined target beam to the FPGA in the AAU, so that the FPGA can query the beam control table based on the beam index to determine the target beam, and then determine the transmitting antenna and antenna configuration information corresponding to the target beam.

[0128] The aforementioned BBU can send beam command information carrying the beam index to the AAU's CPRI interface via the signaling channel in CPRI (Common Public Radio Interface), thereby sending the beam index to the FPGA within the AAU. The beam command information may also include the effective air interface half-frame number, subframe number, time slot number, OFDM (Orthogonal Frequency Division Multiplexing) symbol index flag, etc. The BBU can determine the information in the beam command information other than the beam index using existing techniques, which will not be elaborated further here.

[0129] Specifically, step S103 can be achieved through the following steps E.

[0130] Step E: The FPGA within the AAU of the first base station determines, for each target beam, the transmitting antenna on the first base station used to transmit the target beam, and the antenna configuration information of the transmitting antenna.

[0131] S104: Add each SSB to its assigned position in the corresponding target signal.

[0132] S105: For each target beam, based on the antenna configuration information of the transmitting antenna corresponding to the target beam, the target beam carrying the corresponding target signal is transmitted through the aforementioned transmitting antenna.

[0133] In one embodiment of the present invention, the target beam can be transmitted through the transmitting antenna according to the communication protocol and communication technology on which the base station is based.

[0134] Specifically, the target beam can be transmitted based on the beamforming module in the first base station. In the case that the first base station is an mmWave NR base station, the target beam is an analog beam, and the beamforming module is an analog beamforming module.

[0135] As can be seen from the above, after the first base station determines that its beam has failed, it can reassign the positions of different SSBs in the target signal, allocate target beams to each target signal, and determine the transmitting antennas and their configuration information for transmitting each target beam. Finally, after adding the SSB to the target signal, the transmitting antenna transmits the target beam carrying the target signal according to the antenna configuration information, enabling the first base station to resend the SSB to the terminal, completing the beam retransmission process. Furthermore, this process does not require manual intervention, thus improving the efficiency of beam recovery.

[0136] In one embodiment of the present invention, the beam failure of the first base station can be determined by step A.

[0137] Step A: If a beam failure message is received from the second base station, it is determined that the beam of the first base station has failed.

[0138] Wherein, the frequency of the second frequency band used by the second base station is lower than the frequency of the first frequency band used by the first base station, and the beam fault message is: a message sent by the terminal accessing the first base station and the second base station to the second base station indicating that the beam of the first base station has failed.

[0139] Specifically, if the first base station is an mmWave NR base station, then the second base station can be a 4G-based LTE base station, a 5G-based Sub 6GHz NR base station, etc. If the first base station is a 5G-based Sub 6GHz NR base station, then the second base station can be a 4G-based LTE base station, etc.

[0140] In addition, if the first base station is an mmWave NR base station and the second base station is an LTE base station, then the first base station and the second base station can form an NSA (Non-Standalone) network based on the EN-DC (E-UTRA-NR Dual Connectivity) networking mode.

[0141] The second base station is the primary base station, and the first base station is the secondary base station. The X2 interface of the first base station is connected to the X2 interface of the second base station, enabling communication between the two base stations.

[0142] See Figure 2 This is a schematic diagram of an NSA networking structure provided in an embodiment of the present invention.

[0143] As shown in the diagram, the MME (Mobility Management Entity) is connected to the S1 interface of the LTE base station and to the S1-U interface of the mmWave NR base station. After the terminal connects to the MME, it can access both the LTE base station and the mmWave NR base station. LTE base stations communicate with each other via the X2 interface, as do mmWave NR base stations with LTE base stations. mmWave NR base stations communicate with each other via the X2-U interface.

[0144] The S1 interface, S1-U interface, X2 interface, and X2-U interface mentioned above are all interfaces specified in the 3GPP (3rd Generation Partnership Project) protocol in the existing technology. Please refer to the provisions of the 3GPP protocol, and they will not be described again here.

[0145] In addition, if the first base station is an mmWave NR base station and the second base station is a Sub 6GHz NR base station, the first base station and the second base station can form an SA network based on the NR-DC (NR-NR Dual Connectivity) working mode.

[0146] The second base station is the primary base station, and the first base station is the secondary base station. The Xn interface of the first base station is connected to the Xn interface of the second base station, enabling communication between the two base stations.

[0147] See Figure 3 This is a schematic diagram of an NR-DC network structure provided in an embodiment of the present invention.

[0148] As shown in the diagram, the AMF (Access and Mobility Management Function) is connected to the NG interface of the Sub 6GHz NR base station and to the NG-U interface of the mmWave NR base station. After the terminal connects to the AMF, it can access both the Sub 6GHz NR base station and the mmWave NR base station. Sub 6GHz NR base stations communicate with each other via the Xn interface, as do Sub 6GHz NR base stations and mmWave NR base stations. mmWave NR base stations communicate with each other via the Xn-U interface.

[0149] Among them, the NG interface, NG-U interface, Xn interface and Xn-U interface mentioned above are all interfaces specified in the existing 3GPP protocol. Please refer to the provisions of the 3GPP protocol, and they will not be described again here.

[0150] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second frequency band used by the second base station is lower than the frequency of the first frequency band used by the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0151] In another embodiment of the present invention, step S103 can be achieved by step D.

[0152] Step D: For each target beam, determine the transmitting antenna of the first base station corresponding to the target beam, as recorded in the beam control table, and the antenna configuration information of the transmitting antenna.

[0153] The aforementioned beam control table records: the correspondence between the target beam and the panel of the first base station, the correspondence between the target beam and the transmitting antenna in the panel, and the correspondence between the antenna configuration information of the target beam and the transmitting antenna.

[0154] Specifically, each entry in the aforementioned beam control table can record the beam index of the target beam, the subarray identifier of the panel corresponding to the target beam, the antenna identifier of the transmitting antenna corresponding to the target beam, and the antenna configuration information of the transmitting antenna corresponding to the target beam.

[0155] For each target beam, the first base station can look up the beam control table to determine the entry that records the beam index of the target beam, determine the panel corresponding to the subarray identifier recorded in the determined entry as the panel corresponding to the target beam, determine the transmitting antenna in the panel corresponding to the target beam according to the antenna identifier, and determine the antenna configuration information recorded in the determined entry as the antenna configuration information of the transmitting antenna.

[0156] In one embodiment of the present invention, the aforementioned beam control table can be recorded in the FPGA within the AAU, and the FPGA can look up the beam control table to determine the transmitting antenna and antenna configuration information corresponding to each target beam.

[0157] See Figure 4 This is a flowchart illustrating the second beam control method provided in an embodiment of the present invention, which is consistent with the aforementioned... Figure 1 Compared to the embodiment shown, the step S106 is included before step S101.

[0158] S106: Determine the number of SSBs to be transmitted based on beam coverage information.

[0159] The aforementioned beam coverage information indicates the beam coverage range of the first base station.

[0160] Specifically, theoretically, the more beams the first base station transmits, the larger its beam coverage area. Therefore, the larger the beam coverage area of ​​the first base station indicated by the aforementioned beam coverage information, the more beams need to be transmitted. Each beam carries a signal containing one SSB, so the larger the beam coverage area of ​​the first base station indicated by the beam coverage information, the more SSBs need to be transmitted.

[0161] The first base station can be determined to be in a coverage scenario or a capacity scenario based on beam coverage information. If it is currently in a coverage scenario, the number of SSBs can be 16, 32, etc. If it is currently in a capacity scenario, the number of SSBs can be 8.

[0162] In addition, the aforementioned beam coverage information can be pre-set based on the beam coverage range requirements of the first base station.

[0163] In one embodiment of the present invention, the beam coverage information can be recorded in the HL (High Level) within the BBU of the first base station. The MAC within the BBU can obtain the beam coverage information recorded in the HL to determine whether the first base station is in a coverage scenario or a capacity scenario. If it is currently in a coverage scenario, the number of SSBs can be determined.

[0164] As can be seen from the above, the first base station can determine its beam coverage range based on beam coverage information. The larger the beam coverage range of the first base station, the more SSBs can be determined. This allows the first base station to transmit a larger number of target beams, thereby meeting the requirements of the beam coverage range represented by the beam coverage information.

[0165] Furthermore, the aforementioned first base station can also determine the number of SSBs to be transmitted based on application scenario information, so that the number of target beams transmitted by the first base station matches the application scenario of the first base station. Specifically, since the location of the aforementioned first base station is often relatively fixed, and the application scenarios near the first base station are also relatively fixed, the aforementioned application scenario information can be fixed preset information.

[0166] For example, if the application scenario of the first base station indicated by the above application scenario information contains many obstructions, then the number of the above SSBs is large, enabling the first base station to transmit more target beams and provide higher quality communication services to the terminal.

[0167] In the case where the first base station mentioned above is an mmWave NR base station, see [link to relevant documentation]. Figure 5 This is a schematic diagram of the structure of a first base station provided in an embodiment of the present invention.

[0168] The first base station includes a BBU and an AAU. The BBU contains a first interface, HL, L1, L2, and a CPRI interface. The AAU contains a CPRI interface, a millimeter-wave intermediate frequency main control unit, and a millimeter-wave high-frequency front-end. L1 is the physical layer, and L2 is the data link layer.

[0169] Specifically, if the second base station is an LTE base station, the first interface mentioned above is the X2 interface; if the second base station is a Sub6GHz NR base station, the first interface mentioned above is the Xn interface. After receiving a beam fault message through the first interface, the BBU determines that its own beam has failed. The HL records beam coverage information. The MAC layer in L2 determines the number of SSBs to be transmitted based on the beam coverage information recorded in the HL. The MAC layer in L2 determines the position of each SSB in the target signal and the beam index of the target beam corresponding to each target signal. The BBU sends the beam command information carrying the beam index to the CPRI interface of the AAU through its own CPRI interface, so that the AAU can determine each target beam. The FPGA in the millimeter-wave intermediate frequency main control in the AAU can determine the panel, transmitting antenna, and antenna configuration information of the transmitting antenna corresponding to each target beam according to the recorded beam control table. The analog beamforming module in the millimeter-wave high-frequency front-end in the AAU can control the transmitting antenna to transmit the target beam based on the antenna configuration information.

[0170] Corresponding to the aforementioned beam control method applied to the first base station, this embodiment of the invention also provides a beam control method applied to the second base station.

[0171] See Figure 6 The above is a flowchart illustrating the third beam control method provided in this embodiment of the invention, applied to a second base station. The method includes the following steps S601-S602.

[0172] S601: Receives a beam fault message sent by the terminal.

[0173] The aforementioned terminal refers to a terminal that accesses both the first base station and the second base station. The aforementioned beam fault message is a message sent by the terminal indicating that the beam of the first base station has failed. The first base station uses a first frequency band, the second base station uses a second frequency band, and the frequency of the first frequency band is lower than the frequency of the first frequency band.

[0174] Specifically, the terminal is connected to both the first base station and the second base station. The second base station uses a frequency in the second frequency band that is lower than the frequency used by the first base station. Theoretically, the signal coverage of the second base station, which uses a higher frequency band, is greater than the signal coverage of the first base station, which uses a lower frequency band. The terminal has a higher success rate in sending beam fault messages to the second base station, so the second base station can receive the beam fault messages sent by the terminal.

[0175] S602: Forward the aforementioned beam failure message to the aforementioned first base station so that the aforementioned first base station can retransmit the beam.

[0176] Specifically, if the first base station is an mmWave NR base station and the second base station is an LTE base station, the second base station can forward beam fault messages to the first base station through the X2 interface between the second base station and the first base station.

[0177] The connection relationship between the first base station and the second base station can be found in [reference needed]. Figure 2 This will not be elaborated upon here.

[0178] If the first base station is an mmWave NR base station and the second base station is a Sub 6GHz NR base station, the second base station can forward beam fault messages to the first base station through the Xn interface between the second base station and the first base station.

[0179] The connection relationship between the first base station and the second base station can be found in [reference needed]. Figure 3 This will not be elaborated upon here.

[0180] In addition, the aforementioned first base station can adopt the aforementioned Figure 1 The illustrated embodiment retransmits the beam, but other methods can also be used to retransmit the beam, and the embodiments of the present invention do not limit this.

[0181] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second frequency band used by the second base station is lower than the frequency of the first frequency band used by the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0182] Corresponding to the aforementioned beam control method applied to the first base station, this embodiment of the invention also provides a beam control method applied to a terminal.

[0183] See Figure 7 This is a flowchart illustrating the fourth beam control method provided in this embodiment of the invention. It is applied to a terminal, wherein the terminal is connected to a first base station and a second base station, and the first base station uses a first frequency band, the second base station uses a second frequency band, and the frequency of the second frequency band is lower than the frequency of the first frequency band. The method includes the following steps S701-S702.

[0184] S701: Determine whether the beam of the first base station mentioned above has failed.

[0185] If it is determined that the beam of the first base station has failed, then the following step S702 is executed.

[0186] If it is determined that the beam of the first base station has not failed, then continue to detect whether the beam of the first base station has failed, until it is determined that the beam of the first base station has failed, and then execute step S702.

[0187] S702: Send a beam fault message to the second base station indicating that the beam of the first base station has failed, so that the second base station forwards the beam fault information to the first base station and causes the first base station to retransmit the beam.

[0188] Specifically, after the terminal determines that the beam of the first base station has failed, it can send a beam failure message to the second base station. If the first base station is an mmWave NR base station and the second base station is an LTE base station, the second base station can forward the beam failure message to the first base station through the X2 interface between the second base station and the first base station.

[0189] The connection relationship between the first base station and the second base station can be found in [reference needed]. Figure 2 This will not be elaborated upon here.

[0190] In addition, if the first base station is an mmWave NR base station and the second base station is a Sub 6GHz NR base station, the second base station can forward beam fault messages to the first base station through the Xn interface between the second base station and the first base station.

[0191] The connection relationship between the first base station and the second base station can be found in [reference needed]. Figure 3 This will not be elaborated upon here.

[0192] In addition, the aforementioned first base station can adopt the aforementioned Figure 1 The illustrated embodiment retransmits the beam, but other methods can also be used to retransmit the beam, and the embodiments of the present invention do not limit this.

[0193] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second frequency band used by the second base station is lower than the first frequency band of the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0194] Corresponding to the aforementioned beam control method applied to the first base station, this embodiment of the invention also provides a base station.

[0195] See Figure 8 This is a schematic diagram of the structure of a first type of base station provided in an embodiment of the present invention. The base station, as the aforementioned first base station, includes a memory 801, a transceiver 802, and a processor 803.

[0196] The memory 801 is used to store computer programs; the transceiver 802 includes a BBU and an AAU, used to send and receive data under the control of the processor; the processor 803 is used to read the computer program in the memory and perform the following operations:

[0197] After determining that the beam of the base station has failed, for each SSB, the position of the SSB in the target signal is assigned, wherein the target signal is the signal carrying the SSB to be transmitted by the base station, and the assigned position includes the time domain position and frequency domain position of the SSB in the signal.

[0198] Based on communication information, the target beam corresponding to each target signal is determined, wherein the communication information represents the communication status between the base station and the terminals within its own cell service range;

[0199] For each target beam, determine the transmitting antenna on the base station used to transmit the target beam, and the antenna configuration information of the transmitting antenna;

[0200] Each SSB is added to its assigned position in the corresponding target signal;

[0201] For each target beam, based on the antenna configuration information of the transmitting antenna corresponding to that target beam, the target beam carrying the corresponding target signal is transmitted through the transmitting antenna.

[0202] As can be seen from the above, after a base station determines that its beam has failed, it can reassign the positions of different SSBs within the target signal, allocate target beams to each target signal, and determine the transmitting antennas and their configuration information for each target beam. Finally, after adding the SSB to the target signal, the base station uses the transmitting antenna to transmit the target beam carrying the target signal according to the antenna configuration information. This allows the base station to resend the SSB to the terminal, completing the beam retransmission process. Furthermore, this process requires no manual intervention, improving beam recovery efficiency.

[0203] In one embodiment of the present invention, a beam failure of the base station is determined by the following method:

[0204] If a beam failure message is received from a low-frequency base station, it is determined that the base station's beam has failed. The frequency of the second frequency band used by the low-frequency base station is lower than the frequency of the first frequency band used by the base station. The beam failure message is a message sent by a terminal accessing the base station and the low-frequency base station to the low-frequency base station, indicating that the base station's beam has failed.

[0205] Specifically, Figure 8 The base station shown is the same as the first base station mentioned earlier, and the low-frequency base station is the same as the second base station mentioned earlier. The relevant details will not be repeated here.

[0206] As can be seen from the above, the terminal can send a beam fault message indicating a beam failure to the low-frequency base station, which then forwards the message to the base station, enabling the base station to confirm its own beam failure. Since the terminal does not directly send the beam fault message to the base station, it can still send the message even if the link between the base station and the terminal fails, allowing the base station to successfully confirm its own beam failure. Furthermore, the second frequency band used by the low-frequency base station is lower than the first frequency band used by the base station. In practice, the stability and coverage of the low-frequency base station are often greater than those of the aforementioned base station. Therefore, compared to the terminal directly sending the beam fault message to the base station, sending the message through the low-frequency base station has a higher success rate, improving beam recovery efficiency.

[0207] In one embodiment of the present invention, determining, for each target beam, the transmitting antenna on the base station used to transmit the target beam, and the antenna configuration information of the transmitting antenna, includes:

[0208] For each target beam, the transmitting antenna of the base station corresponding to the target beam, as recorded in the beam control table, and the antenna configuration information of the transmitting antenna are determined. The beam control table records the correspondence between the target beam and the base station subarray, the correspondence between the target beam and the transmitting antenna in the subarray, and the correspondence between the target beam and the antenna configuration information of the transmitting antenna.

[0209] In one embodiment of the present invention, before assigning the position of each SSB in the target signal, the method includes:

[0210] Based on beam coverage information, the number of SSBs to be transmitted is determined, wherein the beam coverage information represents the beam coverage range of the base station.

[0211] As can be seen from the above, a base station can determine its beam coverage range based on beam coverage information. The larger the beam coverage range of the base station, the more SSBs can be determined. This allows the base station to transmit a larger number of target beams, thereby meeting the beam coverage range requirement indicated by the beam coverage information.

[0212] In one embodiment of the present invention, the above-mentioned allocation of the position of each SSB in the target signal includes:

[0213] The MAC within the BBU of the base station allocates the position of each SSB in the target signal through the BBU backend configuration.

[0214] The step of determining the target beam corresponding to each target signal based on communication information includes:

[0215] The MAC determines the target beam corresponding to each target signal based on communication information;

[0216] For each target beam, determining the transmitting antenna on the base station used to transmit that target beam, and the antenna configuration information of the transmitting antenna, includes:

[0217] For each target beam, the FPGA within the AAU in the base station determines the transmitting antenna on the base station used to transmit that target beam, as well as the antenna configuration information of the transmitting antenna.

[0218] Corresponding to the aforementioned beam control method applied to the second base station, this embodiment of the invention also provides a base station.

[0219] See Figure 9 This is a schematic diagram of the structure of a second type of base station provided in an embodiment of the present invention. As the aforementioned second base station, the base station includes a memory 901, a transceiver 902, and a processor 903.

[0220] Memory 901 is used to store computer programs; transceiver 902 includes a BBU and an AAU, used to send and receive data under the control of the processor; processor 903 is used to read the computer program in the memory and perform the following operations:

[0221] The receiver receives a beam fault message sent by a terminal, wherein the terminal is a terminal that accesses a high-frequency base station and the base station, and the beam fault message is a message sent by the terminal indicating that the beam of the high-frequency base station has failed, wherein the high-frequency base station uses a first frequency band, the base station uses a second frequency band, and the frequency of the second frequency band is lower than the frequency of the first frequency band.

[0222] The beam failure message is forwarded to the high-frequency base station so that the high-frequency base station can retransmit the beam.

[0223] Specifically, Figure 9 The base station shown is the same as the second base station shown above, and the high-frequency base station is the same as the first base station shown above, so it will not be described again here.

[0224] As can be seen from the above, the terminal can send a beam fault message indicating a beam failure at the high-frequency base station to the base station, which then forwards the message to the high-frequency base station, enabling the high-frequency base station to confirm its own beam failure. Since the terminal does not directly send the beam fault message to the high-frequency base station, even if the link between the high-frequency base station and the terminal fails, the terminal can still send the message, allowing the high-frequency base station to successfully confirm its own beam failure. Furthermore, the second frequency band used by the base station is lower than the first frequency band of the high-frequency base station. In practice, the stability and coverage of the second frequency band are often greater than those of the high-frequency base station. Therefore, compared to the terminal directly sending the beam fault message to the high-frequency base station, sending the message through the second frequency band has a higher success rate, improving beam recovery efficiency.

[0225] Corresponding to the aforementioned beam control method applied to terminals, this embodiment of the invention also provides a terminal.

[0226] See Figure 10 This is a schematic diagram of the structure of a terminal provided in an embodiment of the present invention. The terminal is a terminal that accesses a first base station and a second base station, wherein the first base station uses a first frequency band, the second base station uses a second frequency band, and the frequency of the second frequency band is lower than the frequency of the first frequency band. The terminal includes a memory 1001, a transceiver 1002, and a processor 1003.

[0227] Memory 1001 is used to store computer programs; transceiver 1002 is used to send and receive data under the control of the processor; processor 1003 is used to read the computer programs in the memory and perform the following operations:

[0228] Determine whether the beam of the first base station has malfunctioned;

[0229] If so, a beam failure message indicating that the beam of the first base station has failed is sent to the second base station, so that the second base station forwards the beam failure information to the first base station and causes the first base station to retransmit the beam.

[0230] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second frequency band used by the second base station is lower than the first frequency band of the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0231] Corresponding to the aforementioned beam control method applied to the first base station, this embodiment of the invention also provides a beam control device applied to the first base station.

[0232] See Figure 11 This is a schematic diagram of the structure of a first type of beam control device provided in an embodiment of the present invention, applied to a first base station. The device includes:

[0233] The location determination module 1101 is used to assign the location of each SSB in the target signal after determining that the beam of the first base station has failed. The target signal is the signal carrying the SSB to be transmitted by the first base station. The assigned location includes the time domain location and frequency domain location of the SSB in the signal.

[0234] The beam determination module 1102 is used to determine the target beam corresponding to each target signal based on communication information, wherein the communication information represents the communication status between the first base station and the terminals within its own cell service range;

[0235] Antenna determination module 1103 is used to determine, for each target beam, the transmitting antenna on the first base station used to transmit the target beam, and the antenna configuration information of the transmitting antenna;

[0236] SSB adding module 1104 is used to add each SSB to the assigned position in the corresponding target signal respectively;

[0237] The beam transmitting module 1105 is used to transmit a target beam carrying the corresponding target signal through the transmitting antenna based on the antenna configuration information of the transmitting antenna corresponding to the target beam for each target beam.

[0238] As can be seen from the above, after the first base station determines that its beam has failed, it can reassign the positions of different SSBs in the target signal, allocate target beams to each target signal, and determine the transmitting antennas and their configuration information for transmitting each target beam. Finally, after adding the SSB to the target signal, the transmitting antenna transmits the target beam carrying the target signal according to the antenna configuration information, enabling the first base station to resend the SSB to the terminal, completing the beam retransmission process. Furthermore, this process does not require manual intervention, thus improving the efficiency of beam recovery.

[0239] In one embodiment of the present invention, the apparatus further includes a fault message receiving module, which is configured to determine that the beam of the first base station has failed by means of the following:

[0240] If a beam failure message is received forwarded by the second base station, it is determined that the beam of the first base station has failed. The second base station uses a second frequency band at a frequency lower than the first frequency band used by the first base station. The beam failure message is a message sent by a terminal connected to both the first and second base stations to the second base station, indicating that the beam of the first base station has failed.

[0241] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second base station uses a lower frequency band than the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0242] In one embodiment of the present invention, the antenna determination module 1103 is specifically used for:

[0243] For each target beam, the transmitting antenna of the first base station corresponding to the target beam, as recorded in the beam control table, and the antenna configuration information of the transmitting antenna are determined. The beam control table records the correspondence between the target beam and the subarray of the first base station, the correspondence between the target beam and the transmitting antenna in the subarray, and the correspondence between the target beam and the antenna configuration information of the transmitting antenna.

[0244] In one embodiment of the present invention, the apparatus further includes a quantity determination module, the quantity determination module being used for:

[0245] Based on beam coverage information, the number of SSBs to be transmitted is determined, wherein the beam coverage information represents the beam coverage range of the first base station.

[0246] As can be seen from the above, the first base station can determine its beam coverage range based on beam coverage information. The larger the beam coverage range of the first base station, the more SSBs can be determined. This allows the first base station to transmit a larger number of target beams, thereby meeting the requirements of the beam coverage range represented by the beam coverage information.

[0247] In one embodiment of the present invention, the position determination module 1101 is specifically used for:

[0248] After determining that the beam of the first base station has failed, the MAC in the BBU of the first base station allocates the position of each SSB in the target signal through the BBU background configuration.

[0249] The beam determination module 1102 is specifically used for:

[0250] The MAC determines the target beam corresponding to each target signal based on communication information;

[0251] The antenna determination module 1103 is specifically used for:

[0252] For each target beam, the FPGA within the AAU of the first base station determines the transmitting antenna on the first base station used to transmit the target beam, as well as the antenna configuration information of the transmitting antenna.

[0253] Corresponding to the aforementioned beam control method applied to a second base station, this embodiment of the invention also provides a beam control device applied to a second base station.

[0254] See Figure 12This is a schematic diagram of the structure of a second beam control device provided in an embodiment of the present invention, applied to a second base station. The device includes:

[0255] The message receiving module 1201 is used to receive a beam fault message sent by a terminal, wherein the terminal is a terminal that accesses the first base station and the second base station, and the beam fault message is a message sent by the terminal indicating that the beam of the first base station has failed, wherein the first base station uses a first frequency band, the second base station uses a second frequency band, and the frequency of the second frequency band is lower than the frequency of the first frequency band.

[0256] The first message sending module 1202 is used to forward the beam failure message to the first base station so that the first base station can retransmit the beam.

[0257] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second base station uses a lower frequency band than the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0258] Corresponding to the aforementioned beam control method applied to a terminal, this embodiment of the invention also provides a beam control device applied to a terminal.

[0259] See Figure 13 This is a schematic diagram of the structure of a third type of beam control device provided in an embodiment of the present invention, applied to a terminal. The terminal is a terminal that accesses a first base station and a second base station, wherein the first base station uses a first frequency band, the second base station uses a second frequency band, and the frequency of the second frequency band is lower than the frequency of the first frequency band. The device includes:

[0260] The fault determination module 1301 is used to determine whether the beam of the first base station has failed.

[0261] The second message sending module 1302 is used to send a beam fault message indicating that the beam of the first base station has failed to pass through the second base station if the determination result of the fault determination module 1301 is yes, so that the second base station forwards the beam fault information to the first base station and causes the first base station to retransmit the beam.

[0262] As can be seen from the above, the terminal can send a beam fault message indicating that the first base station's beam has failed to reach the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to confirm that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully confirm that its own beam has failed. Furthermore, the second base station uses a lower frequency band than the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message through the second base station has a higher success rate, improving beam recovery efficiency.

[0263] In another embodiment of the present invention, a computer-readable storage medium is also provided, which stores a computer program that, when executed by a processor, implements the steps of any of the beam control methods applied to the first base station described above.

[0264] When controlling the beam using the computer-readable storage medium provided in this embodiment of the invention, after the first base station determines that its own beam has failed, it can reallocate the positions of different SSBs in the target signal, assign target beams to each target signal, and determine the transmitting antennas used to transmit each target beam, as well as the antenna configuration information of the transmitting antennas. Finally, after adding the SSB to the target signal, the target beam carrying the target signal is transmitted using the transmitting antenna according to the antenna configuration information, enabling the first base station to resend the SSB to the terminal, completing the beam retransmission process. Furthermore, the above process does not require manual intervention, which can improve the efficiency of beam recovery.

[0265] In another embodiment of the present invention, a computer-readable storage medium is also provided, which stores a computer program that, when executed by a processor, implements the steps of any of the beam control methods applied to the second base station described above.

[0266] When transmitting a beam using the computer-readable storage medium provided in this embodiment of the invention, the terminal can send a beam fault message indicating that the beam of the first base station has failed to transmit to the second base station. The second base station then forwards the beam fault message to the first base station, enabling the first base station to determine that its own beam has failed. Since the terminal does not directly send the beam fault message to the first base station, even if the link between the first base station and the terminal fails, the terminal can still send the beam fault message to the first base station, allowing the first base station to successfully determine that its own beam has failed. Furthermore, the second frequency band used by the second base station is lower than that of the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message to the first base station through the second base station has a higher success rate, improving beam recovery efficiency.

[0267] In another embodiment of the present invention, a computer-readable storage medium is also provided, which stores a computer program that, when executed by a processor, implements the steps of any of the beam control methods applied to a terminal described above.

Furthermore, the second frequency band used by the second base station is lower than that of the first base station. In practice, the stability and coverage of the second base station are often greater than those of the first base station. Therefore, compared to the terminal directly sending the beam fault message to the first base station, sending the beam fault message to the first base station through the second base station has a higher success rate, improving beam recovery efficiency.
