Description

A method and related apparatus for beam measurement reporting

[0001] This application claims priority to Chinese Patent Application No. 202411603694.8, filed on November 8, 2024, entitled "A Method and Related Apparatus for Beam Measurement Reporting", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a method and related apparatus for beam measurement reporting. Background Technology

[0003] With the rapid development of communication technology, communication systems are placing increasingly higher demands on transmission efficiency and quality. For example, terminal devices can measure the beam quality between themselves and network devices (such as base stations) and report this beam quality information to the network devices. By analyzing the reported beam information, the network devices can find higher-quality beams, which helps maintain and improve the performance of the communication system.

[0004] However, the beam information currently reported may not be comprehensive enough, which may cause network devices to be unable to identify better beams, thereby affecting the performance of the communication system. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a method and related apparatus for beam measurement reporting. The purpose is to provide a method for beam measurement reporting that enables terminal devices to report more comprehensive beam information, facilitating network devices in identifying higher-quality beams and thereby maintaining and improving the performance of the communication system.

[0006] Firstly, this application provides a method for beam measurement reporting, applied to a terminal device. In this method, the measurement result of a first beam is first obtained, for example, the measurement result of the first beam may be RSRP or SINR; then, based on the measurement result of the first beam, first information can be sent, wherein the first information is used to indicate relevant information of the first beam and to indicate whether there is relevant information of a second beam. For example, the measurement result of the first beam can be used for event measurement, and the first beam satisfying an event can trigger the reporting of the first information; further example, after obtaining the measurement result of the first beam, event measurement can be used for other beams besides the first beam, and the other beams satisfying events can also trigger the reporting of the first information. For example, the relevant information of the first beam may include the index of the first beam, the measurement result of the first beam, and the event satisfying the first beam, etc.

[0007] Thus, based on the design of the first information, the first information can be made more comprehensive and easier to understand. This allows network devices such as base stations to accurately obtain the relevant information of all beams included in the first information reported by the terminal device. This avoids problems such as incomplete beam-related information obtained by the network device, and prevents errors in judging the better beam. It also helps the network device to accurately determine the beam with better quality, thereby maintaining and improving the performance of the communication system.

[0008] In one possible implementation, the first information may include the number of beams, which indicates whether there is information related to a second beam. For example, if the first beam is a serving beam, a beam number greater than or equal to 1 can indicate that the first information contains information related to a second beam, and the beam indicated by the beam number may not include the first beam; if the first beam is a beam other than a serving beam, a beam number greater than 1, or the sum of the beam numbers in the first information is greater than 1, can indicate that the first information contains information related to a second beam, and the beam indicated by the beam number may include the first beam.

[0009] In this way, the number of beams can implicitly indicate whether the first information includes the information of the second beam in addition to the information of the first beam. This makes it easier for network devices that receive the first information to understand and accurately obtain more information about the beams, which is beneficial for determining a better beam.

[0010] In one possible implementation, the beams indicated by the number of beams can all be located in the first cell where the first beam is located. For example, taking the cell as the dimension, one cell can correspond to one number of beams, and the beams indicated by the number of beams corresponding to the cell are all located in that cell. For example, the number of beams corresponding to the first cell indicates that the beams are all located in the first cell.

[0011] In this way, network devices can determine the number of beams in a cell based on the first information, which makes it easier for network devices to judge the overall situation of the cell. For example, it can determine whether the terminal device needs to switch to a cell with more high-quality beams.

[0012] In one possible implementation, the beam count indicates that the beams are located in at least two cells. For example, the first information can include a beam count, indicating that the beams are located in at least two cells, with all beams as the dimension. This allows network devices to determine the total number of reported beams based on the first information, facilitating the network device's assessment of the overall beam situation and enabling terminal devices to select higher-quality beams.

[0013] In one possible implementation, the beams indicated by the number of beams may also be located in the same cell. For example, the first information reports relevant information about multiple beams indicated by the number of beams, and these multiple beams are located in the same cell, but the first information does not include indication information such as cell index.

[0014] In one possible implementation, the first information may include first indication information, which is used to indicate whether there is relevant information about the second beam. For example, the relevant information about the first beam includes the first indication information, which can indicate whether there is relevant information about the second beam after the relevant information about the first beam.

[0015] Thus, when the number of beams included in the first information is not fixed, the network device can accurately determine whether there is more relevant information about the beams that satisfy the event based on the first indication information.

[0016] In one possible implementation, the first indication information is used to indicate whether there is information about a second beam within the first cell where the first beam is located. This allows network devices to sequentially determine whether there is information about more beams within the cell based on the first information, enabling an assessment of the overall cell situation. For example, it can determine whether a terminal device needs to switch to a cell with more high-quality beams.

[0017] In one possible implementation, the first information is used to indicate information related to the existence of a second beam, either the first beam and the second beam are in the same cell, or the first beam and the second beam are in different cells. This allows network devices to sequentially determine whether there is information related to more beams based on the first information, facilitating the selection of a higher-quality beam by the terminal device.

[0018] In one possible implementation, the first information includes indication information of the first cell and indication information of the first beam in the first cell. This indicates that the first information can be determined based on the indication information of the first cell, and the first beam can be determined based on the indication information of the first beam in the first cell. For example, the indication information of the first cell can be an index of the first cell, and the indication information of the first beam in the first cell can be an index of the first beam in the first cell. This facilitates listing the beams of a cell together.

[0019] In one possible implementation, the first information includes indication information for a first beam, which is used to indicate the first beam from beams located in at least one cell. The beams located in at least one cell include beams indicating the number of beams, or the beams located in at least one cell include a second beam. This indicates that the first beam can be directly determined based on the indication information for the first beam, without the need for indication information for the first cell. This facilitates the direct determination of the index.

[0020] In one possible implementation, the beam indicated by the first information may include beams that satisfy events, and / or, the beams indicating the number of beams may include beams that do not satisfy events, where events indicate conditions related to the measurement results of the beams. A beam that satisfies an event may be the beam that triggers the first information to start, and a beam that does not satisfy an event may be a beam that satisfies a specific event, such as a beam satisfying event 1 but not event 2. That is, for a beam, it can report both satisfied and unsatisfied events. Alternatively, it can also report beams that do not satisfy any event, where a beam that does not satisfy any event may be a beam that satisfies the entry conditions of the event or a beam that does not satisfy the entry conditions.

[0021] Thus, based on the design of the first information, more comprehensive first information can be uploaded, making it easier for network devices to understand the first information and thus determine a better beam.

[0022] In one possible implementation, the first information may include second indication information and / or information related to a triggering event. The second indication information indicates whether the third beam is satisfied or not. For example, the second indication information indicates a third beam satisfaction event, and the information related to the triggering event may be an index of the third beam satisfaction event; conversely, if the second indication information indicates a third beam non-satisfaction event, the information related to the triggering event may be a specific value indicating the non-satisfaction event. This facilitates easier understanding of the first information by network devices, thereby enabling the determination of a higher-quality beam.

[0023] In one possible implementation, the first information can also be used to indicate relevant information about the serving beam, which is the beam currently providing service to the terminal device. This facilitates network devices in comparing the quality of the serving beam with other candidate beams, making it easier to identify the superior beam.

[0024] In one possible implementation, the first beam can be a beam other than the serving beam, and the relevant information of the first beam indicates its quality based on the quality of the serving beam. This facilitates network devices in comparing the quality of the serving beam and the first beam, making it easier to identify a higher-quality beam.

[0025] In one possible implementation, the information related to the first beam indicates the quality of the first beam based on the quality of the serving beam. This can include using the difference between the quality of the first beam and the quality of the serving beam to indicate the quality of the first beam. This facilitates comparison of the quality of the first beam and the serving beam, and also allows for the use of fewer bits to indicate the quality of the first beam, thus saving signaling overhead.

[0026] In one possible implementation, the first information is also used to indicate whether there is information related to the presence of a serving beam. This makes the content of the first information clearer and more comprehensive, facilitating understanding by network devices.

[0027] In one possible implementation, the first information is also used to indicate relevant information about the fourth beam of the cell where the serving beam is located. In this way, the first information can report more beams, making it easier for network devices to identify higher-quality beams.

[0028] In one possible implementation, information about the first beam is used to indicate whether the first beam is active. Thus, for an active beam, the terminal device has already achieved downlink synchronization, allowing the network device to determine whether beam switching is necessary based on whether the terminal device is downlink synchronized, thereby saving resources.

[0029] In one possible implementation, the relevant information of the first beam includes the quality of the first beam, which is obtained based on at least one measurement result of the first beam. This quality may include at least one of the following: the quality of the first beam is obtained based on the most recent quality measurement result; the quality of the first beam is obtained based on the average of the most recent multiple measurement results of the first beam; the quality of the first beam is obtained based on the average of M measurement results of the first beam within a first preset time period, where M ≥ 1; the quality of the first beam is obtained based on the average of N measurement results of the first beam within a second preset time period, where N ≥ 1, and within the second preset time period, the first beam has X measurement results in addition to the N measurement results, where the N measurement results are all higher than the X measurement results, and X ≥ 1. This improves the accuracy of the first information reported by the terminal device to the network device, avoiding deviations caused by fluctuations in the physical layer's beam quality measurement. Furthermore, it allows the network device to obtain more timely or robust beam quality.

[0030] Secondly, this application provides a method for beam measurement reporting, applied to network devices, such as base stations. The method may include: acquiring first information; the first information indicating relevant information about a first beam and indicating whether there is relevant information about a second beam; and then, based on the first information, determining relevant information about the first beam and determining whether there is relevant information about a second beam. The first information may be obtained by a terminal device first acquiring the measurement results of the first beam, and then reported based on these measurement results.

[0031] In this way, network devices can obtain more comprehensive and easier-to-understand first information, so as to accurately obtain the relevant information of all beams included in the first information reported by the terminal device. For example, it can determine whether there is relevant information of the second beam. This can avoid problems such as incomplete beam-related information obtained by network devices, avoid errors in judging better beams, and help network devices accurately determine the beams with better quality, thereby maintaining and improving the performance of the communication system.

[0032] In one possible implementation, the first information includes the number of beams, which is used to indicate whether there is information related to a second beam.

[0033] In one possible implementation, the number of beams indicated by the number of beams is all located in the first cell where the first beam is located.

[0034] In one possible implementation, the number of beams indicates that the beams are in at least two cells.

[0035] In one possible implementation, the first information includes first indication information, which is used to indicate whether there is information related to the presence of a second beam.

[0036] In one possible implementation, the first indication information is used to indicate whether there is information about a second beam within the first cell where the first beam is located.

[0037] In one possible implementation, the first information is used to indicate relevant information about the second beam, which is either in the same cell as the second beam, or in different cells.

[0038] In one possible implementation, the first information includes indication information of the first cell and indication information of the first beam in the first cell.

The beams located in at least one cell include beams indicating the number of beams, or the beams located in at least one cell include a second beam.

[0040] In one possible implementation, the beam indicated by the first information includes beams that satisfy events, and / or the beam indicated by the first information includes beams that do not satisfy events, the events being used to indicate conditions related to the measurement results of the beam.

[0041] In one possible implementation, the first information includes second indication information and / or information related to the triggering event, wherein the second indication information is used to indicate whether the third beam satisfies or fails to satisfy the event.

[0042] In one possible implementation, the first information is also used to indicate relevant information about the serving beam; the serving beam is the beam currently providing services to the terminal device.

[0043] In one possible implementation, the first beam is a beam other than the serving beam, and the relevant information of the first beam indicates the quality of the first beam based on the quality of the serving beam.

[0044] In one possible implementation, the relevant information of the first beam indicates the quality of the first beam based on the quality of the serving beam, including: the difference between the quality of the first beam and the quality of the serving beam indicates the quality of the first beam.

[0045] In one possible implementation, the first information is also used to indicate whether there is relevant information about the serving beam.

[0046] In one possible implementation, the first information is also used to indicate relevant information about the fourth beam of the cell in which the serving beam is located.

[0047] In one possible implementation, information about the first beam is used to indicate whether the first beam is activated.

[0048] In one possible implementation, the relevant information of the first beam includes the quality of the first beam, which is obtained based on at least one measurement result of the first beam, including at least one of the following: the quality of the first beam is obtained based on the most recent quality measurement result of the first beam; the quality of the first beam is obtained based on the average of the most recent multiple measurement results of the first beam; the quality of the first beam is obtained based on the average of M measurement results of the first beam within a first preset time period; M≥1; the quality of the first beam is obtained based on the average of N measurement results of the first beam within a second preset time period; N≥1, and in the second preset time period, the first beam has X measurement results in addition to the N measurement results, and all N measurement results are higher than the X measurement results, X≥1.

[0049] It should be noted that for the various possible implementation methods of the second aspect, please refer to the introduction of the corresponding implementation methods of the first aspect, which will not be repeated here.

[0050] Thirdly, this application provides a method for beam measurement reporting, applied to a terminal device. The terminal device includes a Medium Access Control (MAC) layer and a physical layer. The method may include: acquiring measurement results of a first beam obtained from the physical layer at the MAC layer; sending first information at the MAC layer based on the measurement results of the first beam; the first information is used to indicate relevant information of the first beam and relevant information indicating whether there is a second beam.

[0051] In this way, the first information can be sent through the interlayer interaction between the MAC layer and the physical layer. Based on the design of the first information, it can be made more comprehensive and easier to understand. This allows network devices such as base stations to accurately obtain the relevant information of all beams included in the first information reported by the terminal device. This avoids problems such as incomplete beam-related information obtained by the network device, and avoids errors in judging the better beam. It helps the network device to accurately determine the beam with better quality, thereby maintaining and improving the performance of the communication system.

[0052] In one possible implementation, after the MAC layer sends first information based on the measurement results of the first beam, the method for reporting beam measurements may further include: sending third indication information from the MAC layer to the physical layer; the third indication information is used to indicate that the physical layer should stop measuring the quality of the beam that satisfies the event. Thus, considering that the quality of the beam that satisfies the event may not change significantly, the physical layer can be instructed to stop the measurement, reducing measurement overhead.

[0053] In one possible implementation, after the MAC layer sends first information based on the measurement results of the first beam, the method for reporting beam measurements may further include: sending a fourth indication message from the MAC layer to the physical layer; the fourth indication message is used to instruct the physical layer to stop sending the measurement results of the beam that satisfies the event to the MAC layer. Thus, considering that the quality of the beam that satisfies the event may not change significantly, the physical layer can be instructed to stop reporting, avoiding frequent reporting and reducing measurement overhead.

[0054] In one possible implementation, the MAC layer has information related to the fifth beam, and the first beam is used to trigger the transmission of first information. The method for reporting beam measurements further includes: sending fifth indication information from the MAC layer to the physical layer; the fifth indication information is used to indicate the most recent measurement result of the fifth beam sent from the physical layer to the MAC layer; correspondingly, the MAC layer sends the first information based on the measurement result of the first beam, including: sending the first information based on the measurement result of the first beam and the most recent measurement result of the fifth beam; the first information is used to indicate the relevant information of the fifth beam. This allows the reported information of the fifth beam to be more real-time and accurate.

[0055] In one possible implementation, after the MAC layer sends the first information based on the measurement results of the first beam, the method for reporting the beam measurement further includes: sending information about the sixth beam Y times at the MAC layer according to a preset period; where Y ≥ 1. This can trigger periodic reporting, allowing network devices to continuously observe information about some beams, facilitating a more accurate determination of a stable and superior beam.

[0056] In one possible implementation, the first beam is used to trigger the transmission of first information, and the sixth beam may include at least one of the following beams: the first beam, at least one other beam in the first cell where the first beam is located, and the beam that satisfies the event. In this way, more comprehensive first information including more beams can be reported, facilitating network devices to determine a better beam.

[0057] In one possible implementation, the sixth beam may include all beams indicated by the first information. This allows for continuous monitoring of relevant information about these reported beams, facilitating the more accurate identification of stable and superior beams.

[0058] In one possible implementation, the beam measurement reporting method further includes: the MAC layer sending a sixth indication message to the physical layer; the sixth indication message indicating the quality of the sixth beam measured at the physical layer, and / or, the sixth indication message indicating the measurement result of the sixth beam being sent from the physical layer to the MAC layer. Thus, periodic reporting can be achieved through inter-layer interactive replication between the MAC layer and the physical layer.

[0059] Fourthly, this application provides a method for beam measurement reporting, applied to network devices, such as base stations. The method may include: acquiring first information; the first information indicating relevant information about a first beam and indicating whether there is relevant information about a second beam; and then, based on the first information, determining relevant information about the first beam and determining whether there is relevant information about a second beam. The first information may be obtained by a terminal device first acquiring the measurement results of the first beam, and then reported based on these measurement results.

[0060] In this way, network devices can obtain more comprehensive and easier-to-understand first information, so as to accurately obtain the relevant information of all beams included in the first information reported by the terminal device. For example, it can accurately determine whether there is relevant information of the second beam. This can avoid problems such as incomplete beam-related information obtained by network devices, avoid errors in judging better beams, and help network devices accurately determine the beams with better quality, thereby maintaining and improving the performance of the communication system.

[0061] In one possible implementation, after the MAC layer sends the first information based on the measurement results of the first beam, the beam measurement reporting method further includes: sending the relevant information of the sixth beam Y times according to a preset period at the MAC layer; Y≥1.

[0104] In the embodiments provided in this application, the terminal device can take various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. A terminal may also be referred to as a terminal device, user equipment (UE), access terminal device, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, terminal device, wireless communication device, UE agent, or UE device, etc. A terminal device can also be a fixed terminal or a mobile terminal.

[0105] The communication system shown in Figure 1 above is merely an example. In actual applications, the communication system may include more numbers or types of devices. This application does not limit the specific architecture of the communication system.

[0106] The following embodiments describe the beam measurement reporting method provided in this application.

[0107] Next, to ensure clarity and conciseness in the description of the following embodiments, the terminology used in the embodiments of this application will be explained. It should be understood that this explanation is for the purpose of better understanding the embodiments of this application and does not necessarily constitute a limitation on the embodiments of this application.

[0108] A beam is a wireless signal directed in a specific direction. By adjusting the shape of the electromagnetic beam transmitted by the antenna, effective communication coverage can be achieved. In the embodiments of this application, terminal devices and network devices can communicate based on beams.

[0109] Service beam: refers to the beam that currently provides services to the terminal equipment, or the beam that indicates the unified transmission configuration status, or the beam associated with the current reference signal.

[0110] In some embodiments, the serving beam can be indicated based on a unified Transmission Configuration Indication (TCI) state, where TCI stands for Transmission Configuration Indication. For example, the serving beam can be a beam corresponding to the indicated TCI state, or it can indicate multiple activated TCI states, where the serving beam is at least one activated beam, and there can be up to eight activated beams.

[0111] For example, the unified TCI state can be indicated by MAC CE / DCI, where MAC CE refers to a Medium Access Control Element (MAC CE) generated by the MAC layer, used to transmit control information; and DCI is a Downlink Control Information (DCI) generated by the physical layer, used to send control commands.

[0112] In some embodiments, beam measurement involves measuring the reference signal (RS) corresponding to the beam. The beam measurement result can be a measurement result of the beam-related synchronization signal block (SSB) or channel state information reference signal (CSI-RS).

[0113] The beam index can be the index of the reference signal (such as the SSB Resource Identifier (SSBRI), CRI, etc.) or the TCI state or beam index.

[0114] For details on SSB, CSI-RS, SSBRI, and CRI, please refer to the following text.

[0115] Serving cell: refers to the cell that currently provides service to the terminal device, and the serving beam is located in the serving cell. The serving cell may also include other beams besides the serving beam.

[0116] Candidate cell: refers to a cell that does not provide service to terminal devices but may become a new serving cell.

[0117] In related technologies, terminal devices can measure the quality of beams included in candidate cells and report the measured beam information, such as the measurement results, to network devices (e.g., base stations). Based on this, the network devices can determine the superior beam, allowing the terminal device to switch to the candidate cell with the better beam. However, the currently reported beam information may not be comprehensive enough, potentially leading to situations where the network device cannot identify all beams based on the reported information. This can result in the network device being unable to determine the superior beam, thus affecting the performance of the communication system.

[0118] Based on this, this application provides a method for beam measurement reporting. In this method, after obtaining the measurement result of a first beam, the terminal device can report first information to the network device based on the measurement result of the first beam. This first information can indicate the relevant information of the first beam and whether there is relevant information of a second beam. For example, the first information can include the number of beams, enabling the network device to clearly determine the amount of relevant information it needs to acquire for each beam. Alternatively, the first information can indicate whether there is relevant information of a second beam in addition to the relevant information of the first beam, enabling the network device to determine whether it needs to continue acquiring relevant information of the second beam. Thus, the first information is more comprehensive, allowing the network device to accurately acquire the relevant information of all beams included in the first information reported by the terminal device. This avoids the problem of incomplete beam information acquired by the network device, which could lead to errors in determining a better beam. This helps the network device accurately identify the beam with better quality, thereby maintaining and improving the performance of the communication system.

[0119] Next, with reference to the communication system shown in Figure 1, the method for beam measurement reporting provided in the embodiments of this application will be introduced.

[0120] Referring to Figure 2, the method for reporting beam measurements may include the following steps:

[0121] S201: The terminal device acquires the measurement results of the first beam.

[0122] In some embodiments, the terminal device includes a physical layer and a medium access control (MAC) layer.

[0123] The physical layer can measure the quality of the first beam and obtain the measurement results of the first beam. The physical layer then reports the measurement results of the first beam to the MAC layer.

[0124] In one example, the network device can send an SSB to the terminal device via a predefined direction of the first beam. The physical layer of the terminal device can receive the SSB and measure the Reference Signal Receiving Power (RSRP) of the SSB as a measurement result of the first beam, or measure the Signal to Interference plus Noise Ratio (SINR) of the SSB as a measurement result of the first beam.

[0125] In another example, the network device can also send CSI-RS to the terminal device via a predefined direction of the first beam. The physical layer of the terminal device can receive the CSI-RS and measure the RSRP of the CSI-RS as the measurement result of the first beam, or measure the SINR of the CSI-RS as the measurement result of the first beam.

[0126] In some embodiments, the first beam may have an index for identifying the first beam.

[0127] It should be noted that the first beam having an index is only an example. The first beam may also have other information for identification, as long as it can identify the first beam. This application does not limit this.

[0128] In one example, the index of the first beam may consist only of the beam index (which may be referred to as the first beam indication information), which can be used to uniquely index the first beam from among the beams included in at least one cell. For example, the index of the first beam may be indexed from the beams indicated by the number of beams in the first information, or the index of the first beam may be indexed from the pair of beams having a second beam.

[0129] See RS index 2 in Table 2 below, which can be the index of the first beam.

[0130] In the example where the measurement result of the first beam is the RSRP of SSB, the index of the first beam can be SSBRI.

[0131] In the example where the measurement result of the first beam is the RSRP of CSI-RS, the index of the first beam can also be the CSI-RS resource indicator (referred to as CRI).

[0132] For example, there are a total of 8 cells, and these 8 cells have a total of 30 beams. The SSBRI or CRI of the first beam can be used to directly index the first beam from the 30 beams.

[0133] In another example, the index of the first beam may include the index of the first cell in which the first beam is located (which may be referred to as the indication information of the first cell), and the index of the first beam in the first cell (which may be referred to as the indication information of the first beam in the first cell), the index of the first beam in the first cell can be used to uniquely index the first beam from among the multiple beams included in the first cell.

[0134] In the example where the RSRP of the first beam is SSB, the index of the first beam may include the Local Traffic Manager Configuration ID (LTM configuration ID) and the SSB, or it may include the candidate cell ID and the SSB. The LTM configuration ID or candidate cell ID is used to index the first cell where the first beam is located, that is, the LTM configuration ID or candidate cell ID is the index of the first cell, and the SSB is used to index the first beam in the first cell, that is, the SSB is the index of the first beam in the first cell.

[0135] In the example where the measurement result for the first beam is the RSRP of CSI-RS, the index of the first beam can include the LTM configuration ID / candidate Cell ID and the CSI-RS ID. The LTM configuration ID is used to index the first cell where the first beam is located, and the CSI-RS ID is used to index the first beam in the first cell. That is, the CSI-RS ID is the index of the first beam in the first cell. For example, see LTM configuration 1 or candidate Cell 1 in Table 1 below (which is another example of cell indexing), which is the index of the first cell, and CSI-RS1 in Table 1 is the index of the first beam in the first cell.

[0136] For example, there are a total of 8 cells, including a first cell, which includes 5 beams, including the first beam. The LTM configuration ID of the first beam can be indexed to the first cell, and the SSBRI or CSI-RS ID of the first beam can be used to index the first beam from the 5 beams of the first cell.

[0137] Furthermore, in some embodiments, the beam index can also be a TCI state, with different beams having different TCI states. It should be noted that the reference signal indices for SBRI and CRI described above can be associated with the corresponding beam, thus allowing indexing to the beam. Similarly, the TCI state can also be associated with and indexed to the beam.

[0138] In addition, in some embodiments, the beam index can also be an index that directly points to the beam, which can be called a beam index that directly points to the beam itself.

[0139] S202: The terminal device sends first information to the network device based on the measurement results of the first beam, and the network device receives the first information accordingly.

[0140] In some embodiments, after the physical layer of the terminal device obtains the measurement result of the first signal, it can send it to the MAC layer of the terminal device. The MAC layer can then send first information to the network device based on the measurement result of the first beam.

[0141] In one possible implementation, the terminal device determines a first beam satisfaction event based on the measurement results of the first beam, which can then trigger the reporting of first information. The first beam can be a candidate beam, in which case the reporting of first information can be triggered by a candidate beam satisfaction event and / or a serving beam satisfaction event; the first beam can also be a serving beam, in which case the reporting of first information can also be triggered by a candidate beam satisfaction event and / or a serving beam satisfaction event.

[0142] In one possible implementation, the terminal device can trigger the reporting of first information based on the measurement results of the first beam, where the measurement results of the first beam meet the entry conditions of the event. If the measurement results of other beams besides the first beam also meet the event, the first information can also include relevant information of the first beam and relevant information of the other beams that meet the event.

[0143] In one possible implementation, the terminal device can either report periodically based on the measurement results of the first beam, or trigger the transmission of the first information. For example, after the last transmission of the first information, if a preset period is reached, the measurement results of the first beam can also trigger the transmission of the first information.

[0144] It should be noted that the relevant introduction to beam satisfaction events can be found in the description of the embodiments below, and will not be elaborated here.

[0145] The first information can be called a MAC control element, or MAC CE for short. It refers to a type of control information in the MAC layer, used to transmit control information. In this embodiment, it is used to transmit information related to the first beam, etc.

[0146] In some embodiments, the measurement results of the first beam can trigger the reporting of first information, causing the terminal device to send the first information, which can indicate the relevant information of the first beam, to the network device. For a detailed description of the triggering of the reporting, please refer to the following embodiments; it will not be elaborated upon here.

[0147] In other embodiments, the reporting of first information may also be triggered by the measurement results of other beams, causing the terminal device to send the first information, which can indicate the relevant information of the first beam, to the network device.

[0148] In some embodiments, the first information is used to indicate relevant information about the first beam and relevant information about whether there is a second beam.

[0149] For example, the first information may indicate the presence of information related to the second beam, so that the network device can continue to acquire information related to the second beam based on the indication.

[0150] For example, the first information may indicate that there is no information related to the second beam, so that the network device does not need to obtain the information related to the second beam based on the indication.

[0151] Next, we will introduce the different forms of information related to whether there is a second beam in the first information indication.

[0152] In one possible implementation, the first information may include the number of beams, which may indicate whether there is information related to the presence of a second beam.

[0153] For example, the number of beams indicated may include the first beam.

[0154] For example, if the number of beams is 3, then the 3 beams indicated by the number of beams include the first beam.

[0155] As another example, the number of beams indicated may exclude the first beam, for example, the first beam may be the serving beam.

[0156] For example, the number of beams can be indicated as the number of beams in a non-serving cell, a neighboring cell, or a candidate cell.

[0157] In one example, the number of beams can be defined by each cell, indicating the number of beams in the first cell that satisfy the event, meaning that all beams indicated by the number of beams are in the first cell.

[0158] For example, if the number of beams is 5, then all 5 beams indicated by the number of beams are in the first cell.

[0159] For example, taking the index of the first cell where the first beam is located as LTM configuration 1 or candidate Cell 1, and the index of the first beam in the first cell as CSI-RS1, see Table 1 for an example of the first information.

[0160] Table 1

[0161] As shown in Table 1, LTM configuration ID or candidate Cell ID, such as LTM configuration 1 / candidate Cell 1, can represent the index of the first cell. RS type indicates the type of reference signal (i.e., SSB or CSI-RS, etc.). Number of beams indicates the number of beams in the first cell that satisfy the event, which can be 3. R is used to indicate reserved fields and is usually set to 0, which can be ignored. RSRP or SINR for the serving beam refers to the quality of the serving beam, which is the corresponding RSRP or SINR. RS index 1 represents the index of a beam (i.e., it can be the index of the beam-associated reference signal, such as SSBRI / CSI mentioned above), for example, it can be the index of the first beam. RSRP or SINR for the RS index 1 is the quality of the first beam indicated by RS index 1. Event indication refers to the index of one or more events satisfied by the beam indicated by RS index 1, which can be the event index (event ID), report configuration index (report config ID), or event type (such as Event LTM2, etc., mentioned below). Among them, an event refers to a condition related to the measurement results of the beam, which can be seen in the detailed introduction below, and will not be elaborated here.

[0162] It should be noted that Table 1 above only uses the example of the first information including the relevant information corresponding to multiple beams in one cell. The first information can also include the relevant information corresponding to beams in multiple cells. For example, in addition to including the content described in Table 1 above, the first information can also include the relevant information of at least one beam in another cell. That is, the first information includes multiple beam numbers, and the multiple beam numbers are used to indicate the number of relevant information of beams in different cells. This application does not limit this.

[0163] Table 1 above only uses the example of the first information including the relevant information corresponding to the three beams in a cell. It can also include the relevant information corresponding to one beam, two beams or more beams.

[0164] For example, the first information may include beam number 1 and beam number 2. Beam number 1 may indicate the number of related information of the beam information of the first cell where the first beam is located, and beam number 2 may indicate the number of related information of the beam information of another cell other than the first cell. That is to say, this application does not limit the number of beams included in the first information.

[0165] In addition, the number of beams can indicate the amount of information related to the beam, or it can simply indicate the number of beams. The amount of information related to the beam can be the same as the number of beams.

[0166] It should be further noted that the quality of the serving beam indicated by RSRP or SINR for the serving beam in Table 1 is only an example. The first information may not include the quality of the serving beam. The number of beams indicating the number of beams in the first cell that meet the event is also only an example. The number of beams can be the number of beams that meet the event and / or the number of beams that do not meet the event, or the number of beams reported. Correspondingly, the event indication can also indicate the events that meet the event and / or the events that do not meet the event (i.e., unmet events). Furthermore, the above-mentioned number of beams (at the cell level) can be the number of beams that meet the event in the cell and / or the number of beams that do not meet the event in the cell and / or the number of beams reported in the cell.

[0167] For example, the number of beams can be the sum of the number of beams that satisfy the event and the number of beams that do not satisfy the event. The event indicator in the relevant information of the beams that do not satisfy the event can indicate that they do not satisfy the event. See the example below, which will not be elaborated here.

[0168] Based on the number of beams in Table 1 above, if the number of beams in a cell is greater than 1, or if the superposition value of the corresponding number of beams in at least two cells is greater than 1 (that is, indicating relevant information about beams in other cells), it indicates that the first information indicates relevant information about the second beam.

[0169] If the first information contains only one number of beams, and that number equals 1, it indicates that the first information indicates that there is no relevant information for the second beam.

[0170] In this example, the relevant information corresponding to at least one beam in a cell can be listed together, taking a cell as the dimension.

[0171] Furthermore, it should be noted that when the first beam is the serving beam, a cell's number of beams = 1 can also indicate that the cell has a second beam. That is, the beams indicated by the number of beams can include beams other than the serving beam.

[0172] In this way, network devices can determine the number of beams that meet the event in a cell based on the first information, and can determine whether the terminal device needs to hand over, such as whether it needs to hand over to a cell with more high-quality beams.

[0173] In another example, the number of beams can be measured in terms of all beams included in multiple cells, indicating the number of beams that satisfy the event.

[0174] For example, the number of beams indicated can be in at least two cells. For instance, if the number of beams is 3, including beams 1 through 3, beam 1 can be in cell 2, and beams 2 and 3 can be in cell 1.

[0175] It should be noted that the number of beams indicated can be in at least two cells, which is just an example. The number of beams indicated can also be in the same cell. For example, if the number of beams is 3, including beams 1 to 3, they are all in cell 2.

[0176] For example, taking the index of the first beam as SSBRI as an example, see Table 2, which shows an example of the first information.

[0177] Table 2

[0178] Based on the number of beams in Table 2 above, a number of beams greater than 1 indicates that the first information indicates the presence of information related to the second beam. A number of beams equal to 1 indicates that the first information indicates the absence of information related to the second beam.

[0179] Furthermore, it should be noted that when the first beam is the serving beam, number of beam = 1 can also indicate the presence of a second beam. That is, the beam indicated by number of beam can include beams other than the serving beam.

[0180] In this example, the relevant information corresponding to multiple beams in multiple cells, as measured by the terminal device, is listed together, taking all beams included in multiple cells as the dimension.

[0181] This makes it easier for network devices to determine the number of beams that meet all the events based on the first information, and makes it easier for terminal devices to determine the best beam.

[0182] Next, we will introduce another form of information indicating whether there is a second beam.

[0183] In one possible implementation, the first information may include first indication information, which indicates whether there is information related to the presence of a second beam.

[0184] In some examples, the first indication information may be included in the relevant information of the first beam. For example, the relevant information of the first beam may include a single bit that is the first indication information. The embodiments described below will use this as an example.

[0185] In other embodiments, the first line of information related to the first beam may have one bit as the first indication information, or the next line may have one bit as the first indication information. This application does not limit this.

[0186] In one example, the data can be analyzed on a per-cell basis. Taking the first cell where the first beam is located as an example, the relevant information of the first beam includes first indication information, which can be used to indicate whether there is relevant information of a second beam within the first cell. In the example where the relevant information of the first beam includes this first indication information, the first indication information can indicate whether there is relevant information of a second beam after the relevant information of the first beam, as described in Table 3.

[0187] See Table 3 for an example of the first information.

[0188] Table 3

[0189] As shown in Table 3, 1 => more event for this beam indicates that there is an event indication for another beam after the beam indexed by RS index1 in the cell indexed by LTM configuration 1 (or candidate Cell ID 1). This can be a satisfied event indication or an unsatisfied event indication. In Table 3, this means that there is another event indication after event indication 1 in this cell, i.e., there is event indication 2. 0 => more event for this beam indicates that there is no event indication after the beam indexed by RS index 2 in the cell indexed by LTM configuration 1. In Table 3, this means that there is no other event indication after event indication 2 in this cell.

[0190] 1 => more beam for this cell indicates that there is another beam after the beam indexed by RS index 1 in the cell indexed by LTM configuration 1, that is, there is a beam indexed by RS index 2.

[0191] 0 => More beam for this cell is the first indication information, indicating that there are no other beams after RS ​​index 2 in the cell indexed by LTM configuration 1.

[0192] The first indication information may include W => more event for this beam and / or W => more beam for this cell. W can be 1 or 0. This application does not limit the value of W, and it can be used to distinguish whether there is information related to a second beam.

[0193] The same applies to the cells indexed by LTM configuration 2 (or candidate Cell ID 2), and will not be repeated here. Further details in Table 3 can be found in Table 1 described above, and will not be repeated here.

[0194] For example, the relevant information of the first beam includes 1 => more beam for this cell, indicating that there is relevant information of the second beam after the relevant information of the first beam indicated by the first information, and the relevant information of the first beam includes 0 => more beam for this cell number of beam, indicating that there is no relevant information of the second beam after the relevant information of the first beam indicated by the first information.

[0195] It should be noted that, based on the first information indicating the relevant information of the first beam and the relevant information of the second beam, it can also indicate whether there is relevant information of another beam besides the first and second beams, and so on. This application does not limit the total number of relevant beams indicated by the first information.

[0196] In some embodiments, the relevant information of the first beam may include indication information indicating whether there is another event after the first beam is satisfied, which indicates whether the first beam is satisfied.

[0197] See Table 4 for an example of the first information.

[0198] Table 4

[0199] As shown in Table 4, assuming the RS index can be the index of the first beam, and the event ID / report config ID can be the index of an event satisfied by the first beam, 1 => more event for this beam indicates that there is another event satisfied by the first beam, and 0 => more event for this beam indicates that there are no more events satisfied by the first beam. In other words, 1 => more event for this beam and 0 => more event for this beam can be the indication information described above, that is, indicating whether there is another event satisfied by the first beam after an event satisfied by the first beam.

[0200] In another example, the dimensions can be all the beams included in multiple cells. The relevant information of the first beam can include first indication information to indicate whether there is relevant information of a second beam after the first beam. The first beam and the second beam can be in the same cell or in different cells, as shown in Table 5.

[0201] See Table 5 for an example of the first information.

[0202] Table 5

[0203] It can be located in one community or in at least two communities; this application does not limit this.

[0204] Thus, when the number of beams included in the first information is not fixed, the network device can accurately determine whether there are more beams that satisfy the event based on the first indication information.

[0205] Next, we will introduce the beam that satisfies the event and the beam that triggers the transmission of the first message.

[0206] In some embodiments, the beam that satisfies the event refers to the beam that triggers the transmission of the first information and / or the beam that triggers beam switching execution.

[0207] For example, the beam that satisfies the event can be a beam that satisfies TTT (see the detailed introduction of TTT below), or a beam that satisfies the TTT entry condition and / or a beam that satisfies the TTT exit condition (also referred to as satisfying the exit condition), and this application does not limit it in this way.

[0208] Next, we will introduce the beam indicated by the first information, that is, the types of beams that the first information may include.

[0209] Based on the above description, the beam indicated by the first information may include beams that satisfy the event and / or beams that do not satisfy the event. Among them, beams that do not satisfy the event may include beams that satisfy the entry conditions of the event but do not trigger reporting or trigger beam switching, and / or beams that do not satisfy the event may also include beams that do not satisfy the entry conditions of the event.

[0210] Among these, reporting beams that fail to meet a requirement can enable network devices to pay attention to these beams and continuously measure them, or network devices can determine beams that meet a requirement based on the beams that fail to meet a requirement.

[0211] In some embodiments, the first information may include second indication information and information related to the triggering event, wherein the second indication information may indicate a third beam satisfaction event or a third beam non-satisfaction event.

[0212] For example, the first information may include a bit as second indication information. For example, the second indication information being 1 can indicate a third beam satisfaction event, and the second indication information being 0 can indicate a third beam non-satisfaction event.

[0213] For example, information related to triggering an event may include the index of the event that the beam that satisfied the event satisfied, such as the event ID, report config ID, or event type LTM as described below. Information related to triggering an event may also include special values ​​indicating the beam that did not satisfy the event, such as 000 or 111 as described below.

[0214] After the MAC layer obtains the beam measurement results, it can configure the events that need to be measured, such as events 1-7 (see the detailed introduction of events below). It can first configure events 1-5 that need to be measured, and then configure the index of the events for the configured events. For example, it can configure event ID / report config ID, as shown in Table 4 above.

[0215] In one scenario, for the third beam that satisfies the event, the relevant information for its triggering event can be the event indication content in Table 1, or it can be the event ID / report config ID in Table 4.

[0216] The third beam can satisfy at least one event. When the third beam satisfies multiple events, the satisfied events can be sorted according to the order of the event indices, such as sorting from smallest to largest or from largest to smallest.

[0217] Taking the order from smallest to largest as an example, among the events corresponding to event 1 to event 5, the indices of multiple events satisfied by the third beam are event 3 and event 5. Therefore, the relevant information for their triggering events is event 3 = 1 and event 5 = 1, respectively. Here, 1 indicates a satisfied event, and 0 can indicate a not satisfied event; this application does not impose any restrictions on this.

[0218] Taking the order from smallest to largest as an example, among the events corresponding to event 1 to event 5, the indices of multiple events satisfied by the third beam are event 3 and event 5, so the relevant information of its triggering event can also be event 1=0, event 2=0, event 3=1, event 4=0 and event 5=1.

[0219] In another scenario, for the third beam whose event is not met, the relevant information for its triggering event can be the event indications in Table 1. For example, there are a total of 6 events, from event 1 to event 6, which can be represented as 001-110 respectively, indicating the events that are met. For instance, the event indication corresponding to RS index 1 in Table 1 can be 001, indicating that the beam indexed by RS index 1 meets event 1. The event indications corresponding to RS index 2 in Table 1 can be 010 and 011, indicating that the beam indexed by RS index 1 meets events 2 and 3 respectively.

[0220] The bit indicating the event for a beam whose event was not met can be 000 or 111, or other special values ​​other than 001-110, indicating that no event was met. For example, the event indicator for RS index 3 in Table 1 can be 000, indicating that the beam indexed by RS index 3 did not meet the event.

[0221] In another scenario, in the first information, the information related to the triggering event of the first beam can indicate the index of the event it satisfies. The information related to the triggering events of subsequent beams indicates whether the event satisfied by the first beam is also satisfied. For example, if the information related to the triggering event corresponding to the first beam is event 5 = 1, it means the first beam satisfies the event indexed by event 5. If the information related to the triggering event corresponding to the second beam after the first beam is 1, it means the second beam also satisfies the event indexed by event 5. If the information related to the triggering event corresponding to the third beam after the second beam is 0, it means the third beam does not satisfy the event indexed by event 5, and so on.

[0222] The information related to the triggering event described above can be found in the event indication location in Table 1.

[0223] Based on the above description, the relevant information for triggering an event can be at least one of the following: the index of the event, the special value of the unmet event, the index of the event that was met by the preceding beam, and the indication information in the relevant information of the following beam indicating whether it meets the event met by the previous beam.

[0224] In some embodiments, the beam indicated by the first information may include the beam of the candidate cell. Furthermore, the beam indicated by the first information may also include the serving beam of the serving cell, that is, the first information may include relevant information about the serving beam.

[0225] In one example, in the first information, the quality of the serving beam indicated (e.g., RSRP or SINR for the serving beam in Table 1) can be the measurement result of the serving beam itself, and the quality of other beams (e.g., the first beam) indicated (e.g., RSRP or SINR for the RS index 1 in Table 1) can be the difference between its own measurement result and the measurement result of the serving beam.

[0226] Furthermore, in some embodiments, in the first information, the quality of the first beam can be its measurement result itself, and the quality of the beams following the first beam can be the difference between its measurement result and the measurement result of the first beam. For example, taking a cell as a dimension, in the first information, the quality of the first beam of a cell can be its measurement result itself, and the quality of the remaining beams in that cell can be the difference between its measurement result and the measurement result of the first beam.

[0227] For example, if the measurement result of the serving beam is 100, in the first information, such as the RSRP or SINR for the serving beam in Table 1, it can be 1100. For instance, if the first beam is the beam of a candidate cell and its measurement result is 88, in the first information, such as the RSRP or SINR for the RS index 1 in Table 1, it represents the quality of the first beam and can be -1100. Similarly, if the first information indicates relevant information about the second beam, which is also the beam of a candidate cell and its measurement result is 108, in the first information, such as the RSRP or SINR for the RS index 2 in Table 1, it represents the quality of the first beam and can be +1000.

[0228] In addition, in some embodiments, the first information may also indicate whether the service beam information is included. For example, a bit may be added to the first information. This bit is a first value (e.g., 1) indicating that there is service beam information, which can be represented by the difference in the previous example to indicate the quality of other beams. This bit is a second value (e.g., 0) indicating that there is no service beam information, which can be represented by the measurement result itself to indicate the quality of other beams.

[0229] Thus, considering that beam quality is usually represented in binary, and beam measurement results generally require about 7 bits, the above method can reduce the number of bits for the quality of the serving beam to about 7 bits, while the quality of other beams can be reduced to about 4 bits. This reduces the number of bits for the first information, lowers signaling overhead, and improves the transmission efficiency of the first information.

[0230] It should be noted that, in the above description, the beam indicated by the first information may include the beam of the candidate cell and the serving beam of the serving cell, or it may include other beams in the serving cell besides the serving beam (also referred to as the fourth beam), such as the activated beam in the serving cell, etc. This application does not limit this.

[0231] Based on the above description, in some embodiments, the relevant information of the first beam can be used to indicate the first beam, the quality of the first beam, and the events satisfied by the first beam, etc.

[0232] For example, information related to the first beam may include an index of the first beam, which indicates the first beam; measurement results of the first beam (or the difference between the measurement results of the first beam and the measurement results of the serving beam), which indicates the quality of the first beam; and an index of events satisfied by the first beam, which indicates events satisfied by the first beam.

[0233] In some embodiments, the information related to the first beam can also be used to indicate whether the first beam is activated. For example, a bit can be added to the first information, where the bit is a third value (e.g., activate = 1) to indicate that the first beam is activated, and the bit is a fourth value (e.g., activate = 0) to indicate that the first beam is not activated.

[0234] The activated first beam indicates that the UE has already performed downlink synchronization with that first beam. Reporting the activation status of the first beam to the network device allows the network device to know that downlink synchronization with the first beam has been completed. This facilitates the network device in selecting the activated beam as the high-quality beam, reducing signaling overhead.

[0235] It should be noted that the relevant information of the first beam may include more or less information than the example above, and this application does not limit this.

[0236] In one possible implementation, the measurement result of the first beam may trigger the terminal device to send the first information to the network device, that is, the first beam triggers the transmission of the first information.

[0237] For example, the measurement result of the first beam may meet the entry condition of an event, and timing may start. During the time-to-trigger (TTT) interval, the measurement result of the first beam continues to meet the event. After the TTT interval ends, the MAC layer may be triggered to send the first information, which is called the first beam meeting the event.

[0238] For example, the events may include events 1-7, wherein the names of events 1-5 may be Event LTM2, Event LTM3, Event LTM4, and Event LTM5, respectively, and the names of events 5, 6, and 7 may be Event LTM7, Event LTM8, and Event LTM9.

[0239] It should be noted that the event name is only an example and may be other names; this application does not limit this.

[0240] Event LTM2 can be defined as the measurement result (also known as quality) of the serving cell's beam falling below a preset absolute threshold, that is, the measurement result of the serving cell's beam is below a first threshold.

[0241] For example, if the first threshold is 75, the TTT is 20ms, and the measurement result of the serving beam is less than 75, it enters Event LTM2. If the measurement result of the serving beam remains less than 75 within 20ms, then the serving beam satisfies Event LTM2 and can trigger the terminal device to send the first information to the network device. If a hysteresis value is configured, then the first threshold is 75, the hysteresis value is 10, the TTT is 20ms, and the measurement result of the serving beam is less than 75-10=65, it enters Event LTM2. If the measurement result of the serving beam is not greater than 75+10=85 within 20ms, then the serving beam satisfies Event LTM2 and can trigger the terminal device to send the first information to the network device.

[0242] Event LTM3 can add the measurement results of the beam of the candidate cell (also known as the neighboring cell of the serving cell) to the measurement results of the beam of the serving cell with a first offset that is higher than the measurement results of the beam of the serving cell.

[0243] Event LTM4 can determine if the beam measurement results of a candidate cell exceed a preset absolute threshold, that is, if the beam measurement results of a candidate cell are higher than a second threshold.

[0244] Event LTM5 can be defined as a situation where the measurement result of the serving cell's beam drops below a preset absolute threshold and the measurement result of the candidate cell's beam is above another preset absolute threshold, i.e., the measurement result of the serving cell's beam is below a third threshold and the measurement result of the candidate cell's beam is above a fourth threshold.

[0245] Event 5 is defined as the number of candidate cell beams satisfying a preset event exceeding a fifth threshold. The preset event can be any one of LTM2 to 5. For example, if a candidate cell's beams satisfy Event LTM3, and the number of beams satisfying Event LTM3 for that candidate cell also exceeds a preset absolute threshold, that is, the number of beams satisfying Event LTM3 for that candidate cell exceeds the fifth threshold. Alternatively, Event 5 is defined as the number of candidate cell beams satisfying Event LTM5 for both the candidate cell and the serving cell, and the number of beams satisfying Event LTM5 for that candidate cell also exceeds a preset absolute threshold, that is, the number of beams satisfying Event LTM5 for that candidate cell exceeds the fifth threshold.

[0246] Event 6 is defined as the average threshold of the beam measurements that satisfy the preset event being higher than the sixth threshold. The preset event can be any one of LTM2 to 5.

[0247] Event 7 refers to a cell with a known timing advance (TA) for the terminal device, where the beam of that cell is more likely to satisfy the event. For example, the beam of that cell is more likely to satisfy the entry and exit conditions of any of the above events, that is, it is more likely to trigger the transmission of the first information or the execution of beam switching.

[0248] For example, taking Event LTM4 as an example, there is a hysteresis value (Hys) and a second offset. Taking the first beam as the beam of the candidate cell of the known TA of the terminal device as an example, the measurement result of the first beam can be represented as Measurement Result (MS) and the second threshold can be represented as Thresh. Then, if Ms + Hys + offset > Thresh, the first beam can meet the entry condition and enter TTT. Within the event interval of TTT, if Ms - Hys - offset < Thresh, it means that the first beam can meet the exit condition and can trigger the reporting of the first information or the execution of beam switching.

[0249] For example, if the second threshold is 100, the hysteresis value is 2, the second offset is 5, and the TTT is 20ms, the measurement result of the first beam plus 2 plus 5 is greater than 100, that is, the measurement result of the first beam is greater than 93, which meets the entry condition of Event LTM4 and can enter Event LTM4. Within 20ms, the measurement result of the first beam minus 2 minus 5 is greater than 100, that is, the measurement result of the first beam is greater than 107, which meets the exit condition of Event LTM4 and can also trigger the terminal device to send the first information to the network device.

[0250] For cells where the terminal device has an unknown TA, assuming that beam 1 is the beam of a candidate cell where the terminal device has an unknown TA, if Ms+Hys>Thresh, then beam 1 can meet the entry condition and enter TTT. Within the event interval of TTT, if Ms-Hys<Thresh, it means that beam 1 can meet the exit condition and can trigger the reporting of the first information or the execution of beam switching.

[0251] For example, if the second threshold is 100, the hysteresis value is 2, the TTT is 20ms, and the measurement result of beam 1 plus 2 is greater than 100, that is, the measurement result of beam 1 is greater than 98, the entry condition of Event LTM4 is met, and it can enter Event LTM4. Within 20ms, the measurement result of beam 1 minus 2 is greater than 100, that is, the measurement result of beam 1 is greater than 102, the exit condition of Event LTM4 is met, and it can also trigger the terminal device to send the first information to the network device.

[0252] The beam of the serving cell mentioned above can be a serving beam or an active beam, and the beam of the candidate cell can be the best beam, a configured beam, an active beam, or an indicated beam within the candidate cell. This application does not limit this.

[0253] In some embodiments, the beam can trigger the transmission of the first information if it satisfies any of the events described above.

[0254] In some embodiments, beam switching can also be triggered when the beam satisfies Event LTM3, Event LTM5, Event 5 or Event 7, that is, the serving beam of the terminal device is switched to the beam that satisfies these events, so that the serving beam of the terminal device is a better beam.

[0255] It should be noted that the events that trigger beam switching described above are merely examples. There may be more or fewer events than those in the examples above, and this application does not limit this.

[0256] Accordingly, when beam switching is triggered, the terminal device can switch the serving beam to the beam that triggered the beam switching.

[0257] Thus, based on the design of the first information, the relevant information of the beam can be clearly, reasonably and comprehensively indicated, which makes it easier for network devices to fully and accurately understand the first information reported by the terminal device, thereby determining a better beam and improving the performance of the communication system.

[0258] Next, we will introduce the quality of the beam indicated by the first piece of information.

[0259] The following description uses the quality of the first beam as indicated in the relevant information of the first beam as an example. You can refer to RS index 1 in Table 1, which points to beam 1. RSRP or SINR for the RS index 1 can indicate the quality of the first beam.

[0260] In one example, the quality of the first beam can be the most recent measurement result of the first beam. For example, if the measurement results of the first beam are 95, 100, 90, and 93 in chronological order, then the quality of the first beam is 93.

[0261] In another example, the quality of the first beam can be the average of the most recent measurements of the first beam. For example, if the measurements of the first beam are 97, 100, 90, and 93 in chronological order, then the quality of the first beam is 95.

[0262] In another example, the quality of the first beam can also be the average of M measurements of the first beam within a first preset time period, where M can be a value greater than or equal to 1. The first preset time period can be the time interval between TTTs or other values, which are not limited in this application. For example, if the quality measurements of the first beam within the TTT are 88, 102, 86, and 76 respectively, then the quality of the first beam is 88.

[0263] In another example, the quality of the first beam can also be the best N measurements among X+N measurements of the first beam within a second preset time. The second preset time can be the TTT time interval, or other values, which are not limited in this application. For example, if X is 2 and N is 4, and the quality measurements of the first beam within the TTT are 75, 88, 102, 86, 73, and 76 respectively, then the quality of the first beam is the average of these four values, 88, 102, 86, and 76. 88, 102, 86, and 76 are all higher than 75 and 73.

[0264] It should be noted that the quality of the first beam can include at least one of the above examples, indicating that the quality of the first beam can be represented by one or more qualities.

[0265] It should be further clarified that the multiple averages of the most recent measurement results, the first preset time, the second preset time, and the N best values ​​within the second preset time in the example above can all be configured by the network device to be sent to the terminal device. For example, they can be configured by Radio Resource Control (RRC). They can also be indicated by the MAC layer of the terminal device to the physical layer.

[0266] This improves the accuracy of the first information reported by the terminal device to the network device, avoids the problem of deviation caused by the fluctuation of beam quality in the physical layer measurement, and enables the network device to obtain more timely or robust beam quality.

[0267] Example 3:

[0268] Next, taking a terminal device including a MAC layer and a physical layer as an example, we will introduce a beam measurement reporting method provided in this application.

[0269] S301: The terminal device obtains the measurement results of the first beam obtained from the physical layer at the MAC layer.

[0270] S302: The terminal device sends first information to the network device at the MAC layer based on the measurement results of the first beam, and the network device receives the first information accordingly.

[0271] The first information is used to indicate relevant information about the first beam and relevant information about whether there is a second beam.

[0272] The implementation methods of S301-S302 can be found in the description of S201-S202, and will not be repeated here.

[0273] Next, we will continue to introduce the interaction between the MAC layer and the physical layer of the terminal device.

[0274] In one possible implementation, after the terminal device sends the first information to the network device, the MAC layer can send a third indication to the physical layer, which can instruct the physical layer to stop measuring the quality of the beam that satisfies the event.

[0275] The beam for the satisfied event can be the beam for the satisfied information indicated by the first information, and / or the beam for the satisfied event in the MAC layer other than the beam indicated by the first information.

[0276] In some embodiments, the third indication information may include the beam index and an instruction to stop measuring beam quality.

[0277] For example, the first information includes beams 1-10, all of which satisfy the event. After the MAC layer reports the first information to the network device, the MAC layer can send the indexes corresponding to beams 1-10 respectively and the instruction to stop measuring beam quality as the third indication information to the physical layer.

[0278] Accordingly, in some embodiments, the physical layer can stop measuring the quality of the beam indicated by the third indication information based on the third indication information.

[0279] In one possible implementation, after the terminal device sends the first information to the network device, the MAC layer can send a fourth indication message to the physical layer, which can instruct the physical layer to stop sending the measurement results of the beam that satisfies the event to the MAC layer.

[0280] The beam for the satisfied event can be the beam for the satisfied information indicated by the first information, and / or the beam for the satisfied event in the MAC layer other than the beam indicated by the first information.

[0281] In some embodiments, the fourth indication information may include the beam index and an instruction to stop reporting beam quality.

[0282] For example, based on the previous example, the first information includes beams 1-10, and all beams 1-10 satisfy the event. After the MAC layer reports the first information to the network device, the MAC layer can send the indexes corresponding to beams 1-10 respectively and the instruction to stop reporting beam quality as the fourth indication information to the physical layer.

[0283] Accordingly, in some embodiments, the physical layer may continue to measure the beam quality indicated by the third indication information based on the fourth indication information, but no longer report the measurement results; the physical layer may also stop measuring the beam quality indicated by the third indication information based on the fourth indication information.

[0284] In some embodiments, the third indication information may further include time t1, which may instruct the physical layer to stop measuring the quality of the beam that indicates the satisfaction event within time t1.

[0285] In some embodiments, the fourth indication information may further include time t2, which may instruct the physical layer to stop reporting measurement results of the indicated beam within time t2.

[0286] In one example, t1 and t2 can be configured by the network device to send data to the end device; for example, they can be configured using RRC.

[0287] In another example, t1 and t2 can also be indicated by the MAC layer of the terminal device to the physical layer, for example, determined based on the number of beams being measured by the physical layer, which is not limited in this application.

[0288] Thus, considering that the quality of the beam that satisfies the event may remain unchanged, avoiding the terminal device from continuously measuring the beam quality or frequently reporting the beam quality can reduce the power consumption of the terminal device.

[0289] In one possible implementation, before the terminal device sends the first information to the network device, the MAC layer can send a fifth indication message to the physical layer, which can be used to request the most recent measurement results of some specific beams (which may be referred to as the fifth beam) from the physical layer.

[0290] As described above, the first information sent by the terminal device to the network device may include information related to the beam that triggered the reporting. For example, if the measurement result of the first beam satisfies TTT, it triggers the reporting of the first information. The MAC layer may have other beams that satisfy the event (which may not have triggered the reporting), and the MAC layer may report them together. However, the measurement results of these beams that satisfy the event may have been measured by the physical layer a long time ago and may have changed. Therefore, the physical layer may be requested to provide the most recent measurement result.

[0291] In some embodiments, taking the MAC layer reporting relevant information of A beams as an example, where there are B beams, and the time for the MAC layer to obtain their measurement results has exceeded time t3, the MAC layer can request the most recent measurement results of these B beams from the physical layer.

[0292] Subsequently, the MAC layer can report to the network device through the first information based on the most recent measurement results of the B beams and the measurement results of the other beams in the A beams excluding the B beams. That is, the relevant information corresponding to the B beams in the first information reported includes the most recent measurement results.

[0293] Accordingly, in some embodiments, the physical layer can report the measurement results of the fifth beam indicated by the fifth indication information based on the fifth indication information.

[0294] In some examples, t3 can be a configuration sent from the network device to the terminal device; for example, it can be an RRC configuration. t3 can also be indicated by the MAC layer of the terminal device. t3 can also be specified by the protocol between the terminal device and the network device; this application does not limit this.

[0295] In one possible implementation, after the terminal device sends the first information to the network device, the MAC layer can periodically report to some specific beams (which can be called the sixth beam).

[0296] Taking the transmission of the first information triggered by the first beam as an example, the sixth beam may include at least one of the following beams: the first beam, at least one or more other beams in the first cell where the first beam is located, and the beam that satisfies the event.

[0297] The beam that satisfies the event can be the beam that satisfies the event in the first information, and / or the beam that satisfies the event other than the first information available at the MAC layer. That is, when the trigger period is reported, the relevant information of any beam that satisfies the event can be reported, regardless of whether it is the beam indicated by the first information.

[0298] For example, the first information includes the relevant information corresponding to beams 1-10 respectively. Beams 1-3 trigger the reporting of the first information, beams 4-8 satisfy the event, beams 9-10 do not satisfy the event, beams 11-15 are other beams of the cell where beams 1-3 are located, and beams 16 and 18 satisfy the event.

[0299] In some embodiments, these specific beams may include all beams included in the first information. Based on the previous example, this includes beams 1 through 10. It should be noted that these specific beams may or may not consistently satisfy the event.

[0300] In some embodiments, these specific beams may include at least one of the following beams: the beam that triggers the first information reporting (e.g., the beam that meets the TTT or the TTT exit condition), such as beams 1-3 above; at least one other beam in the cell where the beam that triggers the first information reporting is located, such as beams 11-15; and the beam that meets the event (which may be indicated by the first information or may be other than the first information indicated by the MAC layer), such as beams 1-8, beam 16, and beam 18.

[0301] The periodic reporting interval (i.e., the preset period) and the number of periodic reports (and Y, Y≥1) can be configured by the network device to be sent to the terminal device. For example, it can be configured by RRC; or it can be indicated by the MAC layer of the terminal device. This application does not limit this.

[0302] Furthermore, in some embodiments, the measurement results of the sixth beam can be available at the MAC layer, that is, reported from the physical layer to the MAC layer.

[0303] In some embodiments, the MAC layer may request the physical layer to send a sixth indication message to the physical layer, for example, the MAC layer may send a sixth indication message to the physical layer to instruct the physical layer to measure the quality of the sixth beam, and / or the sixth indication message may be used to instruct the physical layer to send the measurement results of the sixth beam to the MAC layer.

[0304] For example, the sixth indication information may include an index of the sixth beam, an instruction to report beam quality, and / or an instruction to measure beam quality.

[0305] Thus, based on the inter-layer interaction between the MAC layer and the physical layer, the physical layer can be instructed to stop measuring the quality of some beams, or to stop reporting the measurement results of some beams, reducing the measurement overhead of the physical layer. Periodic reporting can also be triggered, allowing network devices to continuously monitor relevant information about some beams, facilitating the more accurate identification of stable and superior beams. Furthermore, the most recent measurement results for some beams can be requested, ensuring more real-time and accurate initial information.
