[0031] The following describes in detail embodiments of the present disclosure, 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.

[0032] In order to better understand the beam measurement method, apparatus, terminal device, and network device 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.

[0033] Please refer to Figure 1, which is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. Figure 1 takes the communication system as a satellite communication system and the network device as a satellite as an example.

[0034] As shown in FIG1 , the satellite communication system may include but is not limited to a network device 101 and a terminal device 102 .

[0035] In some embodiments, the network device 101 is, for example, a node or device that connects a terminal device to a wireless network. The network device may include at least one of a satellite, an evolved NodeB (eNB), a next generation evolved NodeB (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 RAN, a cloud RAN, a base station in other communication systems, and an access node in a Wi-Fi system, but is not limited thereto. The satellite may be a high-orbit satellite, a ground-orbit satellite, or a medium-orbit satellite.

[0036] In some embodiments, the terminal device 102 includes, for example, at least one of a mobile phone, a wearable device, an Internet of Things device, a car with communication capabilities, a smart car, an aircraft, a tablet computer, a computer with wireless transceiver capabilities, 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 a wireless terminal device in a smart home, but is not limited thereto.

[0037] 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 skilled 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.

[0038] Taking the above-mentioned satellite communication system as an example, referring to FIG2 , assuming that the coverage range of the satellite's service cell on the ground is the rectangular area shown in FIG2 , the area of ​​the rectangular area is 754 km (kilometers) * 1060 km, and the beam width is 50-60 km. Based on the satellite's signal coverage area requirements and the planning and design of the beam width, the number of beams within the satellite's service cell must be at least 128 or 256, etc., to support coverage of hundreds of thousands of square kilometers. The service cell of a network device in the embodiments of the present disclosure refers to the signal coverage range of the network device on the ground.

[0039] Terminal devices need to measure the number of all beams within the satellite's service cell. As the number of beams within a cell increases, terminal devices must scan and measure more beams to identify and obtain the beam with the best communication quality. This increases the terminal's beam measurement and maintenance overhead, increases the power consumption of the terminal's beam measurement, and affects the terminal's battery life. Furthermore, the latency required for the terminal to identify the optimal beam from a large number of beams also increases with the number of beams required to be measured. This can negatively impact terminal handovers, cell selection, or reselection, potentially affecting subsequent data transmission, residency, or access operations, reducing user experience and performance. Furthermore, the coverage of a satellite's service cell slides on the ground as the satellite moves. Given the relatively high speed of low-orbit satellites, the coverage of ground-based mobile cells provided by such satellites also changes rapidly. Therefore, terminal devices must perform relatively frequent beam measurements and cell changes, which increases the complexity of beam measurement.

[0040] 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.

[0041] Embodiments of the present application provide a beam measurement method, apparatus, communication device, communication system, and storage medium. A terminal device can receive a system broadcast message from a network device, determine a target beam to be measured from the multiple beams based on coverage information of multiple beams in the system broadcast message, and perform scanning measurements on the target beam. This reduces the number of beams required to be measured by the terminal device, reduces the complexity and power consumption of beam measurement, and improves the battery life of the terminal device. Furthermore, by reducing the number of beams required to be measured by the terminal device, the delay in the terminal device identifying the optimal beam from multiple beams can be further reduced.

[0042] 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.

[0043] The following embodiments of the present disclosure may be applied to the communication system shown in Figure 1 or some of the entities therein, but are not limited thereto. The entities shown in Figure 1 are examples. The communication system may include all or some of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, whether direct or indirect, and wired or wireless.

[0044] The beam measurement method proposed in the embodiment of the present disclosure is described in detail below.

[0045] FIG3 is a flow chart of a beam measurement method according to an embodiment of the present disclosure.

[0046] It should be noted that the method is performed by a beam measurement device. The beam measurement device may be a terminal device, or configured in a terminal device, which is not limited in this disclosure. The embodiments of this disclosure are described using the beam measurement device as an example of a terminal device.

[0047] As shown in FIG3 , the method involved in the embodiment of the present disclosure includes the following steps 301 - 303 .

[0048] Step 301: Receive a system broadcast message from a network device, where the system broadcast message carries coverage information of multiple beams.

[0049] 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.

[0050] In some embodiments, the multiple beams include beams corresponding to all beam positions within a serving cell of the network device, wherein the beams corresponding to some beam positions may be SSB beams for transmitting synchronization signal blocks (SSBs), wherein each SSB beam corresponds to one SSB.

[0051] In some embodiments, the multiple beams include beams corresponding to all beam positions within a serving 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.

[0052] 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.

[0053] In some embodiments, the system broadcast message is a system message that can be defined as SIB22 (system message 22), which is used to broadcast system information of the service cell to the terminal device, so that the terminal device can determine the target beam to be measured from multiple beams based on the message.

[0054] 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).

[0055] The scheduling of the OSI message, i.e., 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 the 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 this time-frequency position, wherein the OSI message includes SIB22.

[0056] 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).

[0057] Step 302: Determine a target beam to be measured from the multiple beams according to coverage information of the multiple beams.

[0058] 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.

[0059] In some embodiments, the number of target beams is lower than the number of the plurality of beams in step 301 .

[0060] Step 303: Scan and measure the target beam.

[0061] In some embodiments, when a terminal device measures a beam within its serving cell, it may preferentially scan and measure a target beam within the serving cell, that is, the terminal device may only maintain the target beam within the serving cell.

[0062] In summary, the beam measurement method provided by the embodiments of the present disclosure involves a terminal device receiving a system broadcast message from a network device, wherein the system broadcast message carries coverage information for multiple beams; based on the coverage information for the multiple beams, a target beam to be measured is determined from the multiple beams; and a scanning measurement is performed on the target beam. This reduces the number of beams that the terminal device needs to measure, reduces the complexity and power consumption of beam measurement, and improves the battery life of the terminal device. Furthermore, by reducing the number of beams that the terminal device needs to measure, the latency for the terminal device to identify the optimal beam from multiple beams can be further reduced.

[0063] 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.

[0064] FIG4 is a flow chart of a beam measurement method according to an embodiment of the present disclosure.

[0065] It should be noted that the method is performed by a beam measurement device. The beam measurement device may be a terminal device, or configured in a terminal device, which is not limited in this disclosure. The embodiments of this disclosure are described using the beam measurement device as an example of a terminal device.

[0066] As shown in FIG4 , the method involved in the embodiment of the present disclosure includes the following steps 401 - 404 .

[0067] Step 401: Receive a system broadcast message from a network device, wherein the system broadcast message carries coverage information of multiple beams.

[0068] It is understood that the ground coverage of a service cell of a network device can be divided into multiple beam positions, and these beam positions are scanned sequentially by a beam, thereby achieving beam scanning. In some embodiments, the coverage information may include: one or more of: the number of beam positions, beam position positions, beam radius, and beam position arrangement.

[0069] The number of wave bits refers to the number of wave bits contained in the service cell of the network device, that is, the number of beams contained in the service cell of the network device.

[0070] The beam position may include the location of each beam position within the service cell of the network device, or the location of one or more beam positions, and this disclosure is not limited thereto. For example, if multiple beams are SSB beams, all SSB beams within the service cell of the network device may be numbered sequentially, 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.

[0071] The beam radius may include the radius of each beam within the service cell of the network device.

[0072] The waveband arrangement mode is the arrangement mode of all wavebands in the service cell of the network device.

[0073] 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 within the serving cell of the network device.

[0074] As another possible implementation, the coverage information of multiple beams carried in the system broadcast message may include the following four types: the number of beam positions, beam position, beam radius, and beam position arrangement.

[0075] For example, assuming the satellite's service cell covers the rectangular area shown in Figure 2, and each beam has the same radius, the coverage information for multiple beams carried in the system broadcast message can include the following four parameters: the number of beam positions, beam position locations, beam radius, and beam position arrangement. The number of beam positions can include two parameters: the number of beam positions along the long side and the number of beam positions along the short side. The beam radius can include two parameters: the beam radius along the long side and the beam radius along the short side. The beam position includes the beam position corresponding to the starting beam.

[0076] 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.

[0077] It should be noted that the position coordinates of a certain beam position in the embodiments of the present disclosure can be obtained by establishing an x-axis in the direction of the satellite orbit, establishing a y-axis perpendicular to the direction of the satellite orbit, using the sub-satellite point as the coordinate origin, and using the offset of the beam position relative to the sub-satellite point as the position coordinates of the beam position. The sub-satellite point is the center point of the satellite's projection on the plane containing the x-axis and y-axis.

[0078] Step 402: Generate a beam transmission pattern based on the coverage information, wherein the beam transmission pattern represents an arrangement of beam positions corresponding to multiple beams within a service cell of the network device.

[0079] 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.

[0080] For example, assuming that multiple beams are SSB beams, continuing with 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.

[0081] 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 arrangement is arranged along the vertical track.

[0082] The SSB beams are numbered sequentially, starting with the smallest number, SSB#0. With the sub-satellite point in Figure 5 as the coordinate origin, and based on the coverage message, the beam transmission pattern shown in Figure 5 can be generated. Taking the number "0" in Figure 5 as an example, the square where "0" is located represents the beam position corresponding to the beam numbered SSB#0. Taking the number "1" in Figure 5 as an example, the square where "1" is located represents the beam position corresponding to the beam numbered SSB#1, and so on for other numbers. It should be noted that the squares in Figure 5 only illustrate the arrangement and distribution of the beam positions and do not represent the coverage range of the beam positions.

[0083] Step 403: Determine a target beam from multiple beams according to the beam transmission pattern.

[0084] In some embodiments, all of the multiple beams are 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 identity of the SSB beam used to transmit the 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 beams whose corresponding wave positions include the target position of the terminal device or are adjacent to the target position of the terminal device.

[0085] 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 the first candidate beam from multiple beams, wherein the wave 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.

[0086] 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 some SSB beams can be determined from the first candidate beams as target beams, and the present disclosure does not limit this.

[0087] 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.

[0088] In some embodiments, the first candidate beam may be determined based on at least one of the following principles.

[0089] Principle 1: Distance Principle

[0090] The beam within a radius R from the target location of the terminal device is used as the first candidate beam. R is a preset distance and can be set as needed.

[0091] 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.

[0092] Principle 2: Beam Correlation Principle

[0093] 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 that can be set as needed.

[0094] Correspondingly, the first candidate beam determined from the multiple beams satisfies the following condition: the number of beams is a preset number M.

[0095] Principle 3: Received signal quality principle

[0096] N1 beams among the multiple beams whose signal received power is greater than a power threshold are determined as first candidate beams. The power threshold can be set as needed. N1 is an integer greater than 0.

[0097] Correspondingly, the first candidate beam determined from the multiple beams satisfies the following condition: the signal receiving power is higher than the power threshold.

[0098] Principle 4: Received signal quality principle

[0099] Arrange the multiple beams in descending order of signal reception power, and determine the top N2 beams as first candidate beams, where N2 is an integer greater than 0.

[0100] Accordingly, the first candidate beam determined from the multiple beams satisfies the following condition: the signal reception power is higher than the signal reception power of the first beam, wherein the first beam is a beam among the multiple beams other than the first candidate beam.

[0101] From the above analysis, it can be seen that the first candidate beam determined from the multiple beams can meet at least one of the following conditions:

[0102] The wave position is within a preset area, where the preset area is an area with the target location of the terminal device as the center and a preset distance as the radius;

[0103] The number of beams is the preset number;

[0104] The signal receiving power is higher than the power threshold;

[0105] The signal reception power is higher than the signal reception power of the first beam, where the first beam is a beam other than the first candidate beam among the multiple beams.

[0106] For example, referring to FIG6 , assuming the network device is a satellite and the multiple beams are all SSB beams, based on the satellite's ephemeris information, beam transmission pattern, and the target location of the terminal device, the terminal device's target location is determined to be within the beam position corresponding to beam numbered SSB#37, i.e., the terminal device is currently within the coverage of beam numbered SSB#37. Candidate beams are determined based on the beam correlation principle, where a preset number M is 9. Then, an SSB beam whose beam position includes the terminal device's target location and eight SSB beams whose beam positions are adjacent to the terminal device's location, i.e., nine 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 first candidate beams, and all 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.

[0107] 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 identifier of the SSB beam used to transmit SSB in 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 SSB beam that is strongly correlated with the terminal device usually has a corresponding wave position close to the target position where the terminal device is located, 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 where the terminal device is located, or the SSB beam adjacent to the target position where the terminal device is located.

[0108] Accordingly, step 403 can be implemented in the following manner: based on the indication information and the beam transmission pattern, determining 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, determining 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; and determining the target beam from the second candidate beam.

[0109] 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 some SSB beams can be determined from the second candidate beams as target beams, and the present disclosure does not limit this.

[0110] 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.

[0111] 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:

[0112] 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;

[0113] The number of beams is the preset number;

[0114] The signal receiving power is higher than the power threshold;

[0115] The signal reception power is higher than the signal reception power of the second beam, where the second beam is a beam other than the second candidate beam among the multiple beams.

[0116] Step 404: perform scanning measurement on the target beam.

[0117] Referring to Figure 7, taking the network device as a satellite as an example, when the terminal device determines that 9 target beams closely related to its position are {Beam X1, Beam X2, Beam X3, Beam X4, Beam X5, Beam X6, Beam X7, Beam X8, Beam X9} from multiple beams, the terminal device can only perform scanning measurements on these 9 beams when performing beam measurement.

[0118] In some embodiments, when the terminal device is in a connected state, that is, when the terminal device is in communication connection with the network device, the terminal device performs a scanning measurement on the target beam, and after obtaining the measurement report, it can send the measurement report to the network device in accordance with the rules of the measurement mechanism in the relevant technology to report the measurement results to the network device.

[0119] In summary, the beam measurement method provided by the embodiment of the present disclosure is as follows: a terminal device receives a system broadcast message from a network device, wherein the system broadcast message carries coverage information of multiple beams; a beam transmission pattern is generated based on the coverage information, wherein the beam transmission pattern represents the arrangement of the wave positions corresponding to the multiple beams within the service cell; a target beam is determined from the multiple beams based on the beam transmission pattern; and a scanning measurement is performed on the target beam. 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 optimal beam from multiple beams can be further reduced.

[0120] FIG8 is a flow chart of a beam measurement method according to an embodiment of the present disclosure.

[0121] It should be noted that the method is performed by a beam measurement device. The beam measurement device may be a network device or configured in a network device, which is not limited in this disclosure. The embodiments of this disclosure are described using the beam measurement device as an example.

[0122] As shown in FIG8 , the method involved in the embodiment of the present disclosure includes the following steps 801 .

[0123] Step 801: Send a system broadcast message to the terminal device; wherein the system broadcast message carries coverage information of multiple beams, which is used to determine the target beam to be measured from the multiple beams and perform scanning measurement on the target beam.

[0124] In some embodiments, the multiple beams include beams corresponding to all beam positions within a serving cell of the network device, wherein the beams corresponding to some beam positions may be SSB beams for transmitting SSBs, wherein each SSB beam corresponds to one SSB.

[0125] In some embodiments, the multiple beams include beams corresponding to all beam positions within a serving 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.

[0126] 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.

[0127] In some embodiments, the system broadcast message is a system message that can be defined as SIB22 (system message 22), which is used to broadcast system information of the service cell to the terminal device, so that the terminal device can determine the target beam to be measured from multiple beams based on the message.

[0128] 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.

[0129] The scheduling of the OSI message, i.e., the time-frequency resources occupied by the OSI message, can be indicated in SIB1. Specifically, the terminal device can first receive the SSB and SIB1, where SIB1 indicates the time-frequency position occupied by the OSI message, so that the terminal device can receive the OSI message at that time-frequency position, where the OSI message includes SIB22.

[0130] 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.

[0131] In some embodiments, the coverage information includes one or more of the number of beam positions, beam position, beam radius, and beam position arrangement.

[0132] 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.

[0133] In summary, the beam measurement method provided by the embodiments of the present disclosure is that a network device sends a system broadcast message to a terminal device, wherein the system broadcast message carries coverage information of multiple beams, and is used to determine the target beam to be measured from the multiple beams and perform scanning measurements on the target beam. This allows the terminal device to 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 battery life performance of the terminal device. In addition, by reducing the number of beams to be measured by the terminal device, the delay for the terminal device to confirm the optimal beam from multiple beams can be further reduced.
