[0003] When the terminal device moves or the antenna direction of the network device changes, the beams configured by the network device to the terminal device can have a beam failure problem. The beam failure can be divided into a Transmission and Reception Point (TRP) level beam failure and a cell level beam failure. At present, the terminal device can report related information to the network device to indicate the cell with a beam failure when detecting the cell level beam failure. However, the terminal device cannot report the TRP level beam failure information to the network device. SUMMARY

[0052] In order to better understand the embodiments of the present application, the professional terms related to the embodiments of the present application are introduced as follows:

[0053] Wave Beam refers to the shape of electromagnetic waves formed by the antenna, and the wave beam mainly includes global wave beam, point-shaped wave beam and shaped wave beam.

[0054] The terminal can be simultaneously configured to enable a transmission and reception point (TRP)-level beam recovery procedure and a cell-level beam recovery procedure. The beam recovery procedure can be a process in which, when the signal quality of a beam between a network device and a terminal device is poor, such as a beam failure caused by an obstacle (such as a human body or a vehicle), the terminal device can report a beam failure event to the network device, and optionally, the terminal device can recommend a new beam to the network device, so as to quickly restore the communication quality between the two. The TRP-level beam recovery procedure refers to a process in which the terminal device can monitor a TRP-level beam failure event and perform beam recovery. The cell-level beam recovery procedure refers to a process in which the terminal device can monitor a cell-level beam failure event and perform beam recovery. Therefore, when the terminal device is simultaneously configured to enable the TRP-level beam recovery procedure and the cell-level beam recovery procedure, the types of beam failure events that the terminal device can monitor include TRP-level beam failure events and / or cell-level beam failure events. The terminal device configured with the beam recovery procedure can detect a beam failure and thus perform a beam failure recovery process. The beam failure event is included in the beam recovery procedure, and for a cell configured with the beam recovery procedure, the terminal device can detect whether the cell has a beam failure event. It should be noted that one cell can be composed of one TRP or multiple TRPs. The TRP is a logical concept, and one TRP can be one entity network site, such as a remote radio head (RRH) or a base station, or one TRP can be composed of multiple entity network sites.

[0055] In order to better understand the embodiments of the present application, the network architecture to which the embodiments of the present application can be applied is described below.

It should be noted that, as Figure 1 The TRP shown can be composed of multiple network devices, and the embodiment of the present application is not limited by one TRP composed of one network device.

The communication method and related devices provided by the present application are described in detail below.

[0063] The embodiments of the present application provide an information transmission method and device, which are described in detail below.

[0064] The embodiments of the present application can include two parts.

[0065] First, the terminal device can determine whether there are any cells with beam failure events among one or more cells configured for the terminal device, and further determine the type of beam failure event, thereby reporting it to the network device through a first indication message. The type of beam failure event can include TRP-level beam failure events and / or cell-level beam failure events. This method enables the terminal device to report TRP-level beam failure events and / or cell-level beam failure events to the network device.

[0066] Secondly, the terminal device can determine the type of beam failure event occurring in one or more cells, and report either first information or second information to the network device based on the type of beam failure event. The first information corresponds to a beam failure event at the TRP level, and the second information corresponds to a beam failure event at the cell level. Through this method, the terminal device can report the corresponding beam failure event using different information.

[0067] Please see Figure 2 , Figure 2 This application provides a flowchart illustrating an information transmission method. The information transmission method includes the following operations 210 to 220. Figure 2 The method shown can be executed by a terminal device or a chip within the terminal device. This method is applied to a terminal device configured with one or more cells, where the beam failure events for these cells include cell-level beam failure events and TRP-level beam failure events. When the terminal device executes... Figure 2 The process shown may include the following steps:

[0068] 210. Determine whether there is a first cell among one or more cells that has experienced a beam failure event.

[0069] Optionally, the one or more cells may be cells configured by the terminal device;

[0070] Optionally, the one or more cells may be serving cells configured on the terminal device;

[0071] The terminal device can determine whether there is a first cell that has experienced a beam failure event by detecting the beams of each cell in one or more cells. The first cell can be a single cell or at least one cell.

[0072] Optionally, the cells included in the first cell are all cells that have experienced beam failure events.

[0073] Optionally, for a cell configured with a cell-level beam failure event, the terminal device can detect a beam failure detection reference signal (BFD RS) in one or more cells configured for the terminal device. When the signal quality of the BFD RS of the cell meets a preset condition, it can be considered that the cell-level beam failure event occurs in the cell; or when the signal quality of the BFD RS of the cell meets the preset condition and a new candidate beam is found, it can be considered that the cell-level beam failure event occurs in the cell. The preset condition can be specified in a protocol or standard.

[0074] Optionally, for a cell configured with a TRP-level beam recovery procedure, the terminal device can also detect the BFD RS corresponding to each TRP in the cell. When the signal quality of the BFD RS of any one of the TRPs in the cell meets a preset condition, it can be considered that the TRP-level beam failure event occurs in the cell.

[0075] It should be noted that one cell can correspond to one or more beams, and one cell can correspond to one or more TRPs. One TRP can correspond to one or more beams. One beam corresponds to one BFD RS. For example, Figure 1 The BFD RS of cell 1 in FIG. 1 is not the same as the BFD RS of TRP1 in cell 2, and the BFD RS of TRP0 is not the same as the BFD RS of TRP1. For example, as shown in Figure 3 FIG. 2 shows a schematic diagram of two cells configured with a TRP-level beam recovery procedure. The BFD RS of TRP0 in cell 2 is not the same as the BFD RS of TRP2 in cell 3; and the BFD RS of TRP1 in cell 2 is not the same as the BFD RS of TRP3 in cell 3.

[0076] The terminal device can detect the BFD RS of each cell to determine whether there is a first cell in which a beam failure event occurs. If a second cell is configured with a cell-level beam recovery procedure, the terminal device can determine that the second cell has a cell-level beam failure event when it is detected that the quality of the BFD RS corresponding to the second cell meets a preset condition. The second cell can be any one of the first cells.

[0077] If the second cell is configured with a TRP-level beam recovery procedure, the terminal device can determine that the second cell has a TRP-level beam failure event when it is detected that the quality of the BFD RS of at least one TRP in the second cell meets a preset condition. The second cell can be any one of the first cells.

[0078] Optionally, if the TRP-level beam recovery procedure and the cell-level beam recovery procedure are configured in the second cell, the terminal device can determine that the cell-level beam failure event occurs in the second cell when detecting that the BFD RS quality of all TRPs in the second cell meets the preset condition.

[0079] 220、When there is a first cell in which a beam failure event occurs, report first indication information to the network device, the first indication information being used to indicate the type of the beam failure event occurred in each cell in the first cell, the type of the beam failure event including a TRP-level beam failure event and / or a cell-level beam failure event.

[0080] In a possible implementation, the first indication information can be reported through media access control (Media Access Control, MAC) control element (Control Element, CE) signaling.

[0081] In a possible implementation, the first indication information can be used to indicate the situation of the beam failure event occurred in each cell in the first cell. Specifically, the first indication information can include one or more indication fields, each indication field can correspond to a cell in which a beam failure event occurs. Each indication field can indicate the situation of the beam failure event occurred in the corresponding cell. For example, a first indication field corresponds to a second cell, a second indication field corresponds to a third cell, and a third indication field corresponds to a fourth cell, and so on, wherein the second cell, the third cell and the fourth cell are all cells in which a beam failure event occurs. The first indication field can indicate the situation of the beam failure event occurred in the second cell, the second indication field can indicate the situation of the beam failure event occurred in the third cell, and so on.

[0082] The following describes the situation of the beam failure event occurred in each cell in at least one cell in which a beam failure event occurs, in terms of the indication relationship and method between the first indication field included in the first indication information and the second cell.

[0083] In one possible implementation, the first indication field included in the first indication information may include a first indication, which corresponds to the second cell and is used to explicitly indicate whether the type of beam failure event occurring in the second cell is a cell-level beam failure event or a TRP-level beam failure event. For example, when the first indication is 1, the first indication information indicates that the type of beam failure event occurring in the second cell is a cell-level beam failure event; correspondingly, when the first indication is 0, the first indication information indicates that the type of beam failure event occurring in the second cell is a TRP-level beam failure event.

[0084] In one possible implementation, the first indication information can be used to indicate the type of beam failure event occurring in the second cell, and, if the beam failure event is a TRP-level beam failure, to indicate the TRP of the beam failure event. Specifically, the first indication field in the first indication information may include a first indication and a second indication. The first indication is used to indicate the type of beam failure event, and the second indication is used to indicate the TRP of the beam failure event when the beam failure event is a TRP-level beam failure event. When the first indication is a first bit value, the value of the second indication is the index of the TRP of the beam failure event; when the first indication is a second bit value, the value of the second indication will be invalid, that is, whether the value of the second indication is 1 or 0, the first indication information indicates that a cell-level beam failure event has occurred in the second cell. The aforementioned first bit value and second bit value can be configured or preset by the terminal device or access network device.

[0085] For example, such as Figure 1 As shown, for cell 2, when the first indicator and the second indicator are 0 and 1 respectively from left to right (i.e., the first indicator is 0 and the second indicator is 1), the first indicator indicates that the second cell has experienced a beam failure event of type TRP level, and the TRP of the beam failure event is TRP1. For example, when the first indicator and the second indicator are 0 and 0 respectively, the first indicator indicates that the second cell has experienced a beam failure event of type TRP level, and the TRP of the beam failure event is TRP0. That is, when the first indicator is 0, the value of the second indicator is the index of the TRP of the beam failure event. When the first indicator is 1, the second indicator becomes invalid; that is, when the first indicator and the second indicator are 10 or 11 respectively, the first indicator indicates that the second cell has experienced a beam failure event of type cell level.

[0086] Optionally, when the number of configured TRPs in the second cell is greater than 2, the number of bits of the second indication can be adjusted accordingly. For example, when the number of configured TRPs in the second cell is 3, the number of bits of the second indication can be 2 bits; when the number of configured TRPs in the second cell is 7, the number of bits of the second indication can be 3 bits.

[0087] In a possible implementation, the first indication field in the first indication information can include an X-bit field, the X-bit field corresponding to the second cell, and each bit of the X-bit field one-to-one corresponding to a respective TRP in the second cell, X being an integer greater than 0. The value of each bit of the X-bit field can be used to indicate whether a corresponding TRP has a beam failure event. For example, for the second cell, the field is 001, and the first bit from left to right indicates TRP4, the second bit indicates TRP5, and the third bit indicates TRP6, which means that the field indicates that TRP4 and TRP5 have TRP-level beam failure events. Wherein, TRP4, TRP5 and TRP6 all belong to the second cell.

[0088] Optionally, if the value of the X-bit field is a first preset value, the X-bit field is used to indicate that the second cell has a cell-level beam failure event. For example: the X-bit field is 2 bits, the first preset value is set as 00 or 11, if the X-bit field is 00, the first indication field can indicate that the type of the beam failure event of the second cell is a cell-level beam failure event; or when the X-bit field is 11, the first indication field indicates that the type of the beam failure event of the second cell is a cell-level beam failure event.

[0089] Optionally, if the value of the X-bit field is a second preset value, the first indication information can be used to indicate that the type of the beam failure event of the second cell is a cell-level beam failure event. Wherein, the second preset value can be preconfigured. For example, it can be configured that when the X-bit field is 00, the first indication information indicates that the type of the beam failure event of the second cell is a cell-level beam failure event.

[0090] It should be noted that the indication relationship and method of the first indication field and the second cell can also be applied to the second indication field and the third cell, the third indication field and the fourth cell, and so on. In this way, the first indication information can indicate the situation of the beam failure event of each cell in at least one cell having a beam failure event through different indication fields.

[0091] Through the embodiments of this application, when a terminal device determines that a first cell among one or more cells has experienced a beam failure event, it can report first indication information to a network device. This first indication information can indicate the type of beam failure event occurring in each cell of the first cell. The first indication information can include multiple indication fields, each of which can correspond to a cell, such as the first indication field corresponding to a second cell, the second indication field corresponding to a third cell, and so on.

[0092] The first indication information includes a first indication field that can explicitly indicate the type of beam failure event that occurred in the second cell; it can also indicate the type of beam failure event that occurred in the second cell; and it can also indicate which TRP in the second cell sent the beam failure event when the second cell sends a TRP-level beam failure event.

[0093] Similarly, the second indication field included in the first indication information can also explicitly indicate the type of beam failure event occurring in the third cell; it can also indicate both the type of beam failure event transmitted by the third cell and, in the case of a TRP-level beam failure event occurring in the third cell, which TRP in the third cell transmitted the beam failure event. In this way, the first indication information can indicate the beam failure events occurring in multiple cells that have experienced beam failure events.

[0094] This method allows terminal devices to report beam failure events at the TRP level to network devices, enabling network devices to accurately locate the TRP where the beam failure event occurred and take specific measures to restore the TRP-level beam and restore normal communication connectivity. On the other hand, terminal devices can also report cell-level beam failure events to network devices.

[0095] Please see Figure 4 , Figure 4 A flowchart illustrating another information transmission method is provided for embodiments of this application. This information transmission method includes the following operations 410 to 420. Figure 4 The method shown can be executed by a network device, or by a chip within the network device. When the network device executes... Figure 4 The process shown may include the following steps:

[0096] 410. Receive the first instruction information sent by the terminal device.

[0097] In one possible implementation, the first indication information may be reported via MAC CE signaling, which the network device may receive on a specific uplink channel.

[0098] 420. determine the type of the occurred beam failure event according to the first indication information.

[0099] In a possible implementation, the first indication information can be used to indicate the type of the occurred beam failure event of each cell in the first cell, and the type of the occurred beam failure event can include a TRP-level beam failure event and / or a cell-level beam failure event.

[0100] In a possible implementation, the first indication information can be used to indicate the situation of the occurred beam failure event of each cell in the first cell. Specifically, the first indication information can include one or more indication fields, and each indication field can correspond to a cell that has occurred a beam failure event. Each indication field can indicate the situation of the occurred beam failure event of the corresponding cell. For example, a first indication field corresponds to a second cell, a second indication field corresponds to a third cell, and a third indication field corresponds to a fourth cell, and the second cell, the third cell, and the fourth cell are all cells that have occurred a beam failure event. The first indication field can indicate the situation of the occurred beam failure event of the second cell, the second indication field can indicate the situation of the occurred beam failure event of the third cell, and so on.

[0101] The indication relationship and method between the first indication field and the second cell can also be applied to the second indication field and the third cell, and the third indication field and the fourth cell, and so on. In this way, the first indication information can indicate the situation of the occurred beam failure event of each cell in the first cell through different indication fields.

[0102] The network device can determine the first cell that has occurred a beam failure event and the type of the occurred beam failure event of each cell in the first cell according to the first indication information. Further, if it is determined that the type of the occurred beam failure event of a beam failure (BF) cell is a TRP-level beam failure event, the network device can also determine the TRP in the BF cell that has occurred a beam failure event. Furthermore, the network device can perform beam failure recovery on the cell or the TRP that has occurred a beam failure event as soon as possible, so as to improve the communication quality between the terminal device and the network device as soon as possible.

[0103] Through the embodiments of the present application, the network device can receive the first indication information, determine the type of the occurred beam failure event of each BF cell in the first cell that has occurred a beam failure event according to the first indication information, and determine the TRP in the BF cell that has occurred a beam failure event if the type of the occurred beam failure event of the BF cell is a TRP-level beam failure event. Through this method, the network device can obtain the TRP-level beam failure event and the cell-level beam failure event reported by the terminal device through the first indication information.

[0104] Please refer to Figure 5 , Figure 5 Another information transmission method is provided for the embodiments of the present application. The information transmission method includes operations 510-520. Figure 5 The method execution subject shown can be a terminal device, or can be a chip in the terminal device. The method is applied to a terminal device configured with one or more cells, and types of beam failure events of the one or more cells include a cell-level beam failure event and a TRP-level beam failure event. When the terminal device performs the flow shown in the method, the terminal device can determine the type of the beam failure event occurring in the one or more cells. Figure 5 When the flow shown in the method is performed, the following steps can be included:

[0105] 510. The terminal device determines the type of the beam failure event occurring in the one or more cells.

[0106] The terminal device can determine whether there is a cell in which the beam failure event occurs in the one or more cells configured for the terminal device by detecting the corresponding BFD RS of each cell in the one or more cells, and if there is, the type of the beam failure event occurring can be determined.

[0107] Specifically, for a cell configured with a cell-level beam failure event in the one or more cells configured for the terminal device, the terminal device can detect the BFD RS of the cell. When the signal quality of the BFD RS of the cell meets a preset condition, it can be considered that the type of the beam failure event occurring in the cell is a cell-level beam failure event; or when the signal quality of the BFD RS of the cell meets a preset condition and a new candidate beam is found, it can be considered that the type of the beam failure event occurring in the cell is a cell-level beam failure event. Further, if the type of the beam failure event transmitted by the cell in which the beam failure event occurs in the one or more cells is a cell-level beam failure event, the terminal device can determine that the type of the beam failure event occurring in the one or more cells is a cell-level beam failure event.

[0108] Optionally, for a cell configured with a TRP-level beam recovery process in the one or more cells configured for the terminal device, the terminal device can also detect the BFD RS corresponding to each TRP in the cell. When the signal quality of the BFD RS of any one TRP in the cell meets a preset condition, it can be considered that the type of the beam failure event occurring in the cell is a TRP-level beam failure event. Further, if the type of the beam failure event transmitted by the cell in which the beam failure event occurs in the one or more cells is a TRP-level beam failure event, the terminal device can determine that the type of the beam failure event occurring in the one or more cells is a TRP-level beam failure event.

[0109] Optionally, if the type of the beam failure event sent by the cell in which the beam failure event occurs in the one or more cells includes the cell-level beam failure event and the TRP-level beam failure event, the terminal device can determine that the type of the beam failure event occurring in the one or more cells includes not only the TRP-level beam failure event but also the cell-level beam failure event.

[0110] 520、The terminal device reports first information or second information to the network device according to the type of the occurring beam failure event.

[0111] The first information can be first MAC CE signaling or first scheduling request (SR), and the second information can be second MAC CE signaling or second scheduling request, or the second information is a preamble sequence carried by random access channel (RACH) resources.

[0112] The first information corresponds to the TRP-level beam failure event, and the second information corresponds to the cell-level beam failure event.

[0113] In a possible implementation, when the type of the occurring beam failure event is the TRP-level beam failure event, the terminal device reports the first information. That is, the cells in which the beam failure event occurs in the one or more cells all occur the TRP-level beam failure event, and then the terminal device can report the first information to the network device. The first information indicates the occurring beam failure event of the network device.

[0114] In a possible implementation, when the type of the occurring beam failure event is the cell-level beam failure event, the terminal device reports the second information. That is, the cells in which the beam failure event occurs in the one or more cells all occur the cell-level beam failure event, and then the terminal device can report the second information to the network device. The second information indicates the occurring beam failure event of the network device.

[0115] In a possible implementation, when the type of the occurring beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, the terminal device reports the first information. That is, when the cells in which the beam failure event occurs in the one or more cells include not only the cells in which the TRP-level beam failure event occurs but also the cells in which the cell-level beam failure event occurs, the terminal device can report by using the first information. The first information reported by the terminal device in this case can be preconfigured.

[0116] Optionally, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, the terminal device reports the second information. That is, when there are both the cell in which the TRP-level beam failure event occurs and the cell in which the cell-level beam failure event occurs in the one or more cells, the terminal device can report through the second information. This is because there may be a cell with a higher priority in which the cell-level beam failure event occurs in the one or more cells, and the terminal device can preferentially report the type of the occurred beam failure event of the cell with the higher priority, to ensure the stability of the entire communication system. The terminal device reporting the second information in this case can also be pre-configured.

[0117] In a possible implementation, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the number of the cells in which the TRP-level beam failure event occurs is greater than or equal to the number of the cells in which the cell-level beam failure event occurs, the terminal device reports the first information. Since the number of the cells in which the TRP-level beam failure event occurs is greater than the number of the cells in which the cell-level beam failure event occurs, the terminal device can report the cells in which the TRP-level beam failure event occurs through the first information, so that more cells can be preferentially recovered from the beam failure.

[0118] Correspondingly, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the number of the cells in which the TRP-level beam failure event occurs is less than the number of the cells in which the cell-level beam failure event occurs, the terminal device reports the second information. That is, the number of the cells in which the cell-level beam failure event occurs is greater, so the terminal device should report the cells in which the cell-level beam failure event occurs through the second information.

[0119] In a possible implementation, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the index of the cell with the smallest index in the cells in which the TRP-level beam failure event occurs is less than the index of the cell with the smallest index in the cells in which the cell-level beam failure event occurs, the terminal device reports the first information. That is, when the network device indexes and numbers each cell in the one or more cells, the cells can be arranged in the order from high to low according to the priority level of the cells. When the index of the cell with the smallest index in the cells in which the TRP-level beam failure event occurs is less than the index of the cell with the smallest index in the cells in which the cell-level beam failure event occurs, the priority of the cell in which the TRP-level beam failure event occurs is higher than the priority of the cell in which the cell-level beam failure event occurs. Therefore, the terminal device should report the first information.

[0120] Correspondingly, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the index of the cell with the smallest index in the cells in which the TRP-level beam failure event occurs is greater than or equal to the index of the cell with the smallest index in the cells in which the cell-level beam failure event occurs, the terminal device reports the second information. That is, the priority of the cell in which the TRP-level beam failure event occurs is lower than the cell in which the cell-level beam failure event occurs. Therefore, the terminal device should report the second information.

[0121] In a possible implementation, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the index of the cell with the smallest index in the cells in which the TRP-level beam failure event occurs is less than the index of the cell with the smallest index in the cells in which the cell-level beam failure event occurs, the terminal device reports the second information.

[0122] Correspondingly, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the index of the cell with the smallest index in the cells in which the TRP-level beam failure event occurs is greater than or equal to the index of the cell with the smallest index in the cells in which the cell-level beam failure event occurs, the terminal device reports the first information.

[0123] In a possible implementation, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the primary cell also occurs the cell-level beam failure event, the terminal device reports the second information. This is because the primary cell is more important in one or more cells, and if the primary cell occurs the beam failure event, it is likely to cause other cells to also occur the beam failure event, so the terminal device should report the second information to the network device to let the network device preferentially process the cell beam failure event of the primary cell.

[0124] In a possible implementation, when the type of the occurred beam failure event includes not only the TRP-level beam failure event but also the cell-level beam failure event, and the primary cell also occurs the TRP-level beam failure event, the terminal device reports the second information. This is because the primary cell is more important in one or more cells, and if the primary cell occurs the beam failure event, it is likely to cause other cells to also occur the beam failure event, so the terminal device should report the second information to the network device to let the network device preferentially process the cell beam failure event of the primary cell.

[0125] It should be noted that the above 8 possible implementation manners are in parallel relationship, that is, when the terminal device determines whether to report the beam failure event through the first information or the second information, one of the possible implementation manners can be selected.

[0126] In the embodiment of the application, the terminal device can determine whether to report the occurred beam failure event to the network device through the first information or the second information by analyzing the cell in which the TRP-level beam failure event occurs and / or the cell in which the cell-level beam failure event occurs after determining the type of the beam failure event occurring in one or more cells. The first information can be a first MAC CE or a first scheduling request, corresponding to the TRP-level beam failure event, and the second information can be a second MAC CE, or a second scheduling request, or a preamble sequence carried by a RACH resource, corresponding to the cell-level beam failure event. Through this method, the terminal device can report the corresponding beam failure event through different information respectively.

[0127] Please refer to Figure 6 , Figure 6 A flowchart of another information transmission method is provided for the embodiment of the application. The information transmission method includes operations 610-620. Figure 6 The method execution subject shown can be a network device, or can be a chip in the network device. When the network device executes the flow as shown in Figure 6 , the following steps can be included:

[0128] 610, receiving the first information or the second information reported by the terminal device, the first information or the second information being reported in the case where the terminal device determines that a beam failure event occurs in one or more cells.

[0129] The first information can be a first MAC CE signaling or a first scheduling request (SR), and the second information can be a second MAC CE signaling or a second scheduling request, or the second information is a preamble sequence carried by a RACH resource.

[0130] The specific reporting of the first information or the second information by the terminal device has been described in detail in the embodiments corresponding to Figure 5 , and will not be repeated here.

[0131] 620, determining the type of the occurred beam failure event according to the first information or the second information.

[0132] If the network device determines the type of the beam failure event occurred in the one or more cells according to the first information, it can be determined that the TRP-level beam failure event occurs; if the network device determines the type of the beam failure event occurred in the one or more cells according to the second information, it can be determined that the cell-level beam failure event occurs.

[0133] Through the method, the network device can receive the first information or the second information sent by the terminal device to determine whether there is a cell in which the beam failure event occurs in the one or more cells configured by the terminal device. In this way, the network device can determine different types of beam failure events through different information.

[0134] Please refer to Figure 7 , Figure 7 The unit schematic diagram of the information transmission device provided by the embodiments of the present application is shown.

[0139] In a possible implementation, the first indication information is used to indicate the type of the beam failure event occurred in each cell in the first cell.

[0140] In a possible implementation, the first indication in the first indication field in the first indication information explicitly indicates the type of the beam failure event occurred in the second cell.

[0141] In a possible implementation, the first indication field in the first indication information is used to indicate a type of the occurred beam failure event, and a TRP in which the beam failure event occurs when the type is a TRP-level beam failure event, the TRP belonging to the second cell.

[0142] In a possible implementation, the first indication field in the first indication information includes a first indication and a second indication; the first indication is used to indicate a type of the occurred beam failure event; and the second indication is used to indicate a TRP in which the beam failure event occurs when the type is a TRP-level beam failure event.

[0143] In a possible implementation, the first indication field in the first indication information includes a field occupying X bits, each bit corresponding to a TRP; and a value of each bit is used to indicate whether a beam failure event occurs in the corresponding TRP.

[0144] In a possible implementation, when the field of X bits is a preset bit value, the first indication information is used to indicate that the type of the occurred beam failure event of the second cell is a cell-level beam failure event.
