[0028] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0029] In order to better understand the beam measurement method, apparatus, terminal equipment, and network equipment disclosed in the embodiments of the present disclosure, the communication system to which the embodiments of the present disclosure are applicable is first described below.

[0030] See also Figure 1 , Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. Figure 1 The communication system is a satellite communication system and the network device is a satellite as an example for illustration.

[0031] like Figure 1 As shown, the satellite communication system may include but is not limited to a network device 101 and a terminal device 102.

[0032] In some embodiments, the network device 101 is, for example, a node or device that connects a terminal device to a wireless network, and the network device may include at least one of a satellite, an evolved NodeB (eNB), a next generation eNB (ng-eNB), a next generation NodeB (gNB), a nodeB (NB), a home nodeB (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and an access node in a Wi-Fi system, but is not limited thereto. Among them, the satellite may be a high-orbit satellite, a ground-orbit satellite, or a medium-orbit satellite.

[0033] In some embodiments, the terminal device 102 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, an aircraft, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0034] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0035] Taking the above satellite communication system as an example, refer to Figure 2 , assuming that the coverage of the satellite's service cell on the ground is Figure 2 The rectangular area shown in FIG. 1 is 754 km (kilometers) * 1060 km, and the beam width is 50-60 km. According to the signal coverage area requirements of the satellite and the planning and design of the beam width, the number of beams in the satellite's service cell needs to be at least 128 or 256 to support coverage of hundreds of thousands of square kilometers. The service cell of the network device in the embodiment of the present disclosure refers to the signal coverage range of the network device on the ground.

[0036] The terminal equipment needs to measure the number of all beams in the satellite service cell. As the number of beams in the cell increases, on the one hand, the terminal equipment needs to scan and measure more beams to confirm and obtain the beam with the best communication quality, which leads to a corresponding increase in the beam measurement and maintenance overhead of the terminal equipment, increases the power consumption of the terminal equipment's beam measurement, and affects the endurance performance of the terminal equipment. On the other hand, the delay of the terminal equipment to confirm the best beam from a large number of beams also increases with the number of beams to be measured, which will also have a certain adverse effect on the terminal equipment switching or cell selection or reselection, and may further affect the terminal equipment's subsequent data transmission, residence or access operations, and reduce user experience and performance. In addition, the coverage of the satellite's service cell slides on the ground as the satellite moves. Considering that the movement speed of low-orbit satellites is relatively fast, the coverage of ground mobile cells provided by such satellites will also change rapidly. Therefore, the terminal equipment also needs to perform more frequent beam measurements and cell replacement operations accordingly, and the complexity of beam measurement is high.

[0037] Since the movement area of ​​the terminal device is relatively limited, that is, the terminal device will only be in a certain sub-area of ​​the satellite's service cell at a certain moment, therefore, for a terminal device, there is actually no need to measure all beams in the cell, and only the strongly correlated beams near the terminal device need to be measured.

[0038] The embodiments of the present application provide a beam measurement method, device, communication device, communication system and storage medium, wherein the terminal device can receive a system broadcast message from a network device, determine a target beam to be measured from multiple beams based on the coverage information of multiple beams in the system broadcast message, and perform scanning measurement on the target beam, thereby reducing the number of beams required to be measured by the terminal device, reducing the complexity and power consumption of beam measurement, and improving the endurance performance of the terminal device. In addition, by reducing the number of beams required to be measured by the terminal device, the delay of the terminal device in confirming the best beam from multiple beams can be further reduced.

[0039] The following is a detailed introduction to the beam measurement method, device, communication equipment, communication system and storage medium provided by the present disclosure in conjunction with the accompanying drawings.

[0040] The following embodiments of the present disclosure can be applied to Figure 1 The communication system shown or part of it is not limited to this. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1The number and form of other entities are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is an example, the entities can be connected or disconnected, and the connection can be in any way, which can be direct or indirect, and can be wired or wireless.

[0041] The beam measurement method proposed in the embodiment of the present disclosure is described in detail below.

[0042] Figure 3 It is a flowchart of a beam measurement method according to an embodiment of the present disclosure.

[0043] It should be noted that the method is performed by a beam measurement device. The beam measurement device may be a terminal device, or may be configured in a terminal device, which is not limited in the present disclosure. The embodiment of the present disclosure is described by taking the beam measurement device as a terminal device as an example.

[0044] like Figure 3 As shown, the method involved in the embodiment of the present disclosure includes the following steps 301-303.

[0045] Step 301: Receive a system broadcast message from a network device, wherein the system broadcast message carries coverage information of multiple beams.

[0046] It can be understood that the coverage of the service cell of the network device on the ground can be divided into multiple wave positions, and these wave positions are scanned in sequence by the beam, thereby realizing beam scanning.

[0047] In some embodiments, multiple beams include beams corresponding to all beam positions in a service cell of a network device, wherein beams corresponding to some beam positions may be SSB beams for transmitting synchronization signal blocks (SSB), wherein each SSB beam corresponds to one SSB.

[0048] In some embodiments, the multiple beams include beams corresponding to all beam positions in a service cell of the network device, wherein the beams corresponding to all beam positions may be SSB beams, wherein each SSB beam corresponds to one SSB.

[0049] Among them, the coverage information of multiple beams, including information related to the coverage characteristics of the beams, can be used to determine the arrangement and distribution of the wave positions corresponding to each beam in the service cell of the network device.

[0050] In some embodiments, the system broadcast message, which is a system message, may be defined as SIB22 (system message 22), which is used to broadcast system information of a service cell to a terminal device, so that the terminal device can determine a target beam to be measured from multiple beams based on the message.

[0051] Among them, SIB22 can be sent after the network device sends SSB and RMSI (Remaining Minimum System Information). As a type of OSI (Other System Information) message, it can be broadcast regularly or on demand on PDSCH (Physical Downlink Shared Channel).

[0052] The scheduling of the OSI message, that is, the time-frequency resources occupied by the OSI message, can be indicated in SIB1 (system message 1). That is, the terminal device can first receive SSB and SIB1, wherein SIB1 indicates the time-frequency position occupied by the OSI message, so that the terminal device can receive the OSI message at the time-frequency position, wherein the OSI message includes SIB22.

[0053] In some embodiments, in a satellite communication system, the system broadcast message may be sent after SIB19. Combined with the sending period of the satellite network SSB, the sending period of SIB22 may be set to 640 ms (milliseconds).

[0054] Step 302: Determine a target beam to be measured from the multiple beams according to the coverage information of the multiple beams.

[0055] In some embodiments, the target beam, which is a beam near the terminal device that is strongly correlated with the terminal device, may include at least one SSB beam.

[0056] In some embodiments, the number of target beams is lower than the number of the plurality of beams in step 301 .

[0057] Step 303: Scan and measure the target beam.

[0058] In some embodiments, when the terminal device measures the beam within the serving cell, it may preferentially scan and measure the target beam within the serving cell, that is, the terminal device may only maintain the target beam within the serving cell.

[0059] In summary, in the beam measurement method provided by the embodiment of the present disclosure, the terminal device receives a system broadcast message from a network device, wherein the system broadcast message carries coverage information of multiple beams; based on the coverage information of the multiple beams, the target beam to be measured is determined from the multiple beams; and the target beam is scanned and measured. As a result, the number of beams that the terminal device needs to measure is reduced, the complexity and power consumption of the beam measurement are reduced, and the endurance performance of the terminal device is improved. In addition, by reducing the number of beams that the terminal device needs to measure, the delay for the terminal device to confirm the best beam from multiple beams can be further reduced.

[0060] Combine the following Figure 4 , the process of determining a target beam from multiple beams based on a coverage message in the beam measurement method proposed in an embodiment of the present disclosure is described in detail.

[0061] Figure 4 It is a flowchart of a beam measurement method according to an embodiment of the present disclosure.

[0062] It should be noted that the method is performed by a beam measurement device. The beam measurement device may be a terminal device, or may be configured in a terminal device, which is not limited in the present disclosure. The embodiment of the present disclosure is described by taking the beam measurement device as a terminal device as an example.

[0063] like Figure 4 As shown, the method involved in the embodiment of the present disclosure includes the following steps 401-404.

[0064] Step 401: receiving a system broadcast message from a network device, wherein the system broadcast message carries coverage information of multiple beams.

[0065] It is understandable that the coverage of the service cell of the network device on the ground can be divided into multiple wave positions, and these wave positions are scanned in sequence by beams, thereby realizing beam scanning. In some embodiments, the coverage information may include: one or more of: the number of wave positions, the wave position, the beam radius, and the wave position arrangement mode.

[0066] The number of wave positions refers to the number of wave positions included in the service cell of the network device, that is, the number of beams included in the service cell of the network device.

[0067] The beam position may include the position of each beam position in the service cell of the network device, or the position of one or more beam positions, and the present disclosure does not limit this. For example, if multiple beams are SSB beams, all SSB beams in the service cell of the network device may be numbered in sequence, and the beam position may include the position coordinates of the beam position corresponding to the smallest numbered SSB beam, or the position coordinates of the beam position corresponding to the largest numbered SSB beam.

[0068] The beam radius may include the radius of each beam within the service cell of the network device.

[0069] The wave position arrangement mode is the arrangement mode of all wave positions in the service cell of the network equipment.

[0070] As a possible implementation, the coverage information of multiple beams carried in the system broadcast message may include one of the following: beam position, wherein the beam position may include the position of each beam in the service cell of the network device.

[0071] As another possible implementation, the coverage information of multiple beams carried by the system broadcast message may include the following four types: the number of beam positions, the beam position, the beam radius, and the beam position arrangement method.

[0072] For example, suppose the coverage of the satellite's service cell on the ground is Figure 2 In the rectangular area shown, the radius of each beam is the same, then the coverage information of multiple beams carried by the system broadcast message can include the following four types: the number of wave positions, the wave position position, the beam radius, and the wave position arrangement mode. Among them, the number of wave positions can include two parameters: the number of wave positions in the long side direction and the number of wave positions in the short side direction; the beam radius can include two parameters: the beam radius in the long side direction and the beam radius in the short side direction; the wave position includes the wave position corresponding to the starting beam.

[0073] Among them, the number of wave positions in the long side direction, that is, the number of wave positions contained in the long side direction of the rectangular area; the number of wave positions in the short side direction, that is, the number of wave positions contained in the short side direction of the rectangular area; the beam radius in the long side direction, that is, the radius of the beam in the long side direction of the rectangular area; the beam radius in the short side direction, that is, the radius of the beam in the short side direction of the rectangular area; the wave position corresponding to the starting beam, that is, all beams in the service cell of the network device are numbered in sequence, and the beam corresponding to the smallest number is called the starting beam, and the position of the wave position corresponding to the starting beam is called the wave position corresponding to the starting beam; the wave position arrangement mode, that is, how the wave positions corresponding to each beam from the smallest number to the largest number are arranged, for example, the wave position arrangement mode can be arranged along the horizontal track direction or along the vertical track direction.

[0074] It should be noted that the position coordinates of a certain wave position in the embodiment of the present disclosure can be obtained by the following method: establish an x-axis in the direction of the satellite orbit, establish a y-axis perpendicular to the direction of the satellite orbit, use the sub-satellite point as the coordinate origin, and use the offset of the wave position relative to the sub-satellite point as the position coordinates of the wave position. The sub-satellite point is the center point of the projection of the satellite on the plane where the x-axis and the y-axis are located.

[0075] Step 402: Generate a beam transmission pattern according to the coverage information, wherein the beam transmission pattern represents the arrangement of the beam positions corresponding to the multiple beams in the service cell of the network device.

[0076] The arrangement method can be understood as the arrangement and distribution method of the wave positions corresponding to multiple beams within the service cell of the network device.

[0077] For example, assuming that multiple beams are SSB beams, continuing the above example, the coverage message of multiple beams carried by the system broadcast message includes the following 6 parameters: the number of wave positions in the long side direction, the number of wave positions in the short side direction, the beam radius in the long side direction, the beam radius in the short side direction, the wave position corresponding to the starting beam, and the wave position arrangement method.

[0078] Among them, the number of wave positions in the long side direction is 16, the number of wave positions in the short side direction is 8, the beam radius in the long side direction is 40, the beam radius in the short side direction is 20, the wave position corresponding to the starting beam is [-4, -8], and the wave position is arranged along the vertical track.

[0079] The SSB beams are numbered in sequence starting from the smallest number SSB#0. Figure 5 The subsatellite point in is the coordinate origin. Based on the above coverage message, we can generate Figure 5 The beam transmission pattern shown in FIG. Figure 5 For example, the square where "0" is located represents the wave position corresponding to the beam numbered SSB#0. Figure 5 For example, the square where the number "1" is located indicates the wave position corresponding to the beam numbered SSB#1, and the other numbers are deduced in the same way. It should be noted that Figure 5 The squares in the figure only illustrate the arrangement and distribution of the wave positions, and do not indicate the coverage of the wave positions.

[0080] Step 403: determine a target beam from multiple beams according to the beam transmission pattern.

[0081] In some embodiments, multiple beams are all SSB beams, or some of them are SSB beams, and the system broadcast message does not carry indication information, wherein the indication information is used to indicate the identification of the SSB beam used to transmit SSB among the multiple beams. Since the SSB beam that is strongly correlated with the terminal device usually has a corresponding wave position close to the target position of the terminal device, the target beam to be measured can be determined from the corresponding wave position including the target position of the terminal device, or a beam adjacent to the target position of the terminal device.

[0082] Correspondingly, step 403 can be implemented in the following manner: based on the target position of the terminal device and the beam transmission pattern, determine a first candidate beam from multiple beams, wherein the beam position corresponding to the first candidate beam includes the above-mentioned target position or is adjacent to the above-mentioned target position; determine the target beam from the first candidate beam.

[0083] Among them, all the first candidate beams can be determined as target beams, or some beams can be determined from the first candidate beams as target beams, such as determining some SSB beams from the first candidate beams as target beams, and the present disclosure does not limit this.

[0084] It should be noted that, when the network device is a satellite, when determining the first candidate beam from multiple beams, it can also be determined in combination with the satellite's ephemeris message.

[0085] In some embodiments, the first candidate beam may be determined based on at least one of the following principles.

[0086] Principle 1: Distance Principle

[0087] The beam within a radius R from the target position of the terminal device is used as the first candidate beam, where R is a preset distance and can be set as needed.

[0088] Correspondingly, the above-mentioned first candidate beam determined from multiple beams satisfies the following conditions: the beam position is within a preset area, wherein the preset area is an area centered on the target position of the terminal device and with a preset distance R as a radius.

[0089] Principle 2: Beam Correlation Principle

[0090] Regardless of how the beam moves, the target location of the terminal device and the M beams around it are used as the first candidate beams, where M is a preset number and can be set as needed.

[0091] Correspondingly, the first candidate beam determined from the multiple beams satisfies the following condition: the number of beams is a preset number M.

[0092] Principle 3: Received signal quality principle

[0093] Among the multiple beams, N1 beams whose signal received powers are higher than a power threshold are determined as first candidate beams. The power threshold can be set as required. N1 is an integer greater than 0.

[0094] Correspondingly, the first candidate beam determined from multiple beams satisfies the following condition: the signal receiving power is higher than the power threshold.

[0095] Principle 4: Received signal quality principle

[0096] Arrange the multiple beams in descending order of signal receiving power, and determine the first N2 beams as the first candidate beams, where N2 is an integer greater than 0.

[0097] Correspondingly, the above-mentioned first candidate beam determined from multiple beams satisfies the following condition: the signal receiving power is higher than the signal receiving power of the first beam, wherein the first beam is a beam among the multiple beams except the above-mentioned first candidate beam.

[0098] It can be seen from the above analysis that the first candidate beam determined from the multiple beams can satisfy at least one of the following conditions:

[0099] The wave position is within a preset area, where the preset area is an area with the target position of the terminal device as the center and a preset distance as the radius;

[0100] The number of beams is the preset number;

[0101] The signal receiving power is higher than the power threshold;

[0102] The signal reception power is higher than the signal reception power of a first beam, wherein the first beam is a beam other than the first candidate beam among the multiple beams.

[0103] For example, refer to Figure 6 , assuming that the network device is a satellite, and multiple beams are all SSB beams, based on the satellite's ephemeris information, the beam transmission pattern and the target position of the terminal device, the target position of the terminal device is determined to be located in the wave position corresponding to the beam numbered SSB#37, that is, the terminal device is currently located within the coverage of the beam numbered SSB#37, and the candidate beams are determined based on the beam correlation principle, where the preset number M is 9. Then, an SSB beam whose wave position includes the target position of the terminal device and 8 SSB beams whose wave positions are adjacent to the position of the terminal device, that is, 9 SSB beams numbered {SSB#28, SSB#29, SSB#30, SSB#36, SSB#38, SSB#37, SSB#44, SSB#45, SSB#46}, can be determined as the first candidate beams, and all the first candidate beams are determined as target beams. In addition, as the satellite moves, the position of the sub-satellite point moves, and the first candidate beam is updated accordingly.

[0104] In some embodiments, multiple beams are all SSB beams, or some of them are SSB beams, and the system broadcast message may carry indication information, wherein the indication information is used to indicate the identification of the SSB beam used to transmit SSB among the multiple beams. Based on the indication information and the beam transmission pattern, the arrangement of the wave position of the SSB beam in the service cell can be determined. Since the wave position of the SSB beam that is strongly correlated with the terminal device is usually close to the target position of the terminal device, after determining the arrangement of the wave position of the SSB beam in the service cell, the target beam to be measured can be determined from the SSB beam whose corresponding wave position includes the target position of the terminal device, or is adjacent to the target position of the terminal device.

[0105] Correspondingly, step 403 can be implemented in the following ways: based on the indication information and the beam transmission pattern, determine the arrangement of the wave positions of the SSB beam in the service cell; based on the target position of the terminal device and the arrangement of the wave positions of the SSB beam in the service cell, determine a second candidate beam from the SSB beam, wherein the wave position corresponding to the second candidate beam includes the target position or is adjacent to the target position; determine the target beam from the second candidate beam.

[0106] Among them, all the second candidate beams can be determined as target beams, or some beams can be determined from the second candidate beams as target beams, such as determining some SSB beams from the second candidate beams as target beams, and the present disclosure does not limit this.

[0107] It should be noted that, when the network device is a satellite, when determining the second candidate beam from multiple beams, it can also be determined in combination with the satellite's ephemeris message.

[0108] In some embodiments, the second candidate beam may be determined based on principles similar to the above four principles. Accordingly, the second candidate beam determined from the plurality of beams may satisfy at least one of the following conditions:

[0109] The wave position is within a preset area, where the preset area is an area with the target position as the center and a preset distance as the radius;

[0110] The number of beams is the preset number;

[0111] The signal receiving power is higher than the power threshold;

[0112] The signal reception power is higher than the signal reception power of a second beam, wherein the second beam is a beam other than the second candidate beam among the multiple beams.

[0113] Step 404: perform scanning measurement on the target beam.

[0114] refer to Figure 7Taking the network device as a satellite as an example, when the terminal device determines that 9 target beams closely related to its location are {Beam X1, Beam X2, Beam X3, Beam X4, Beam X5, Beam X6, BeamX7, Beam X8, Beam X9} from multiple beams, the terminal device can only scan and measure these 9 beams when performing beam measurement.

[0115] In some embodiments, when the terminal device is in a connected state, that is, when the terminal device is communicatively connected to a network device, the terminal device performs a scanning measurement on the target beam, and after obtaining a measurement report, it can send a measurement report to the network device in accordance with the rules of the measurement mechanism in the relevant technology to report the measurement result to the network device.

[0116] In summary, in the beam measurement method provided by the embodiment of the present disclosure, a terminal device receives a system broadcast message from a network device, wherein the system broadcast message carries coverage information of multiple beams; generates a beam transmission pattern based on the coverage information, wherein the beam transmission pattern represents the arrangement of the wave positions corresponding to the multiple beams in the service cell; determines a target beam from the multiple beams based on the beam transmission pattern; and performs a scanning measurement on the target beam.

[0117] Figure 8 It is a flowchart of a beam measurement method according to an embodiment of the present disclosure.

[0118] It should be noted that the method is performed by a beam measurement device. The beam measurement device may be a network device, or may be configured in a network device, which is not limited in the present disclosure. The embodiment of the present disclosure is described by taking the beam measurement device as a network device as an example.

[0119] like Figure 8 As shown, the method involved in the embodiment of the present disclosure includes the following steps 801.

[0120] Step 801, sending a system broadcast message to a terminal device; wherein the system broadcast message carries coverage information of multiple beams, and is used to determine a target beam to be measured from the multiple beams, and perform scanning measurement on the target beam.

[0121] In some embodiments, the multiple beams include beams corresponding to all beam positions in a service cell of the network device, wherein beams corresponding to some beam positions may be SSB beams for transmitting SSBs, wherein each SSB beam corresponds to one SSB.

[0122] In some embodiments, the multiple beams include beams corresponding to all beam positions in a service cell of the network device, wherein the beams corresponding to all beam positions may be SSB beams, wherein each SSB beam corresponds to one SSB.

[0123] Among them, the coverage information of multiple beams, including information related to the coverage characteristics of the beams, can be used to determine the arrangement and distribution of the wave positions corresponding to each beam in the service cell of the network device.

[0124] In some embodiments, the system broadcast message, which is a system message, may be defined as SIB22 (system message 22), which is used to broadcast system information of a service cell to a terminal device, so that the terminal device can determine a target beam to be measured from multiple beams based on the message.

[0125] Among them, SIB22 can be sent after the network device sends SSB and RMSI. As a kind of OSI message, it can be broadcast regularly or on demand on PDSCH.

[0126] The scheduling of the OSI message, that is, the time-frequency resources occupied by the OSI message, can be indicated in SIB1. That is, the terminal device can first receive SSB and SIB1, wherein SIB1 indicates the time-frequency position occupied by the OSI message, so that the terminal device can receive the OSI message at the time-frequency position, wherein the OSI message includes SIB22.

[0127] In some embodiments, in a satellite communication system, the system broadcast message may be sent after SIB19. Combined with the sending period of the satellite network SSB, the sending period of SIB22 may be set to 640 ms.

[0128] In some embodiments, the coverage information includes one or more of: the number of beam positions, beam positions, beam radius, and beam position arrangement.

[0129] It should be noted that the process in which the terminal device determines the target beam to be measured from multiple beams based on the coverage message and performs scanning measurement on the target beam can be referred to the embodiment on the terminal device side and will not be repeated here.

[0130] In summary, in the beam measurement method provided by the embodiment of the present disclosure, the network device sends a system broadcast message to the terminal device, wherein the system broadcast message carries the coverage information of multiple beams, and is used to determine the target beam to be measured from the multiple beams, and scan and measure the target beam. The terminal device can determine the target beam to be measured from the multiple beams based on the system broadcast message sent by the network device, thereby reducing the number of beams to be measured, reducing the complexity and power consumption of beam measurement, and improving the endurance performance of the terminal device. In addition, by reducing the number of beams that the terminal device needs to measure, the delay of the terminal device in confirming the best beam from multiple beams can be further reduced.
