Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for triggering beam reporting and beam management. Background Technology

[0002] In communication technology, terminal devices typically need to communicate with network devices based on beams, and the quality of the beam's reference signal usually affects the stability of signal transmission.

[0003] The current protocol proposes that when the measured values ​​of the reference signal quality of a new beam meet a certain relationship, beam reporting or beam management can be triggered to switch the current beam to a new beam with better quality. However, based on current technology, when the measured values ​​of the reference signal quality of a new beam meet a certain relationship, there is a lack of a mechanism to determine whether to trigger beam reporting or beam management. Summary of the Invention

[0004] This application provides a method and apparatus for triggering beam reporting and beam management, which can start a preset timer and counter mechanism to determine whether to trigger beam reporting or beam management when the measured value of the reference signal quality of a new beam meets a certain relationship.

[0005] Firstly, embodiments of this application provide a method for triggering beam reporting, which is applied to a terminal device. This method can be executed by the terminal device itself, or by a chip, module, or unit configured within the terminal device.

[0006] Specifically, the method includes: when the measured value of the reference signal quality of the third beam among the N first beams is first detected to satisfy a first relationship without the timer being started, starting the timer and starting the counter associated with the third beam, wherein the N first beams are beams not associated with the current transmission configuration indicator (TCI) state; detecting the measured value of the reference signal quality of each of the N first beams according to a preset rule within the time window specified by the timer; updating the counter associated with the certain beam when the measured value of the reference signal quality of a certain beam among the N first beams is detected to satisfy the first relationship; setting the counter associated with the fourth beam to 0 when the fourth beam among the N first beams is detected to satisfy the target condition; and sending a first message to the network device when the timer and the counter associated with the N first beams are detected to satisfy the trigger condition, the first message being used to request the network device to start beam management.

[0007] In this application, each of the N first beams can also be referred to as a new beam.

[0008] Among them, the beams that are not associated with the current TCI state can be understood as the beams associated with the TCI states configured by the radio resource control (RRC) or medium access control-control element (MAC-CE) layer, or the beams corresponding to the reference signals configured by downlink signaling.

[0009] It should be understood that the measured value of the reference signal quality of the beam will change over time. Therefore, within the time window specified by the timer, the measured value of the reference signal quality of each beam needs to be continuously detected according to a preset rule, and the counter is updated based on the latest measured value of the detected reference signal quality.

[0010] Based on this implementation, when the terminal device detects for the first time that the measured value of the reference signal quality of a new beam (e.g., the third beam among N first beams) satisfies the first relationship without the timer being started, it can start a timer and counter mechanism to determine whether to trigger beam reporting in order to request the network device to start beam management.

[0011] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0 (e.g., if the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be invalid, and the counter associated with the invalid new beam can be set to 0). This avoids the problem of false triggering caused by the invalid new beam triggering beam reporting, thereby ensuring the stability of signal transmission.

[0012] In conjunction with the first aspect, in some implementations, the target condition includes: the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0013] Here, "reconfigured counter" can be understood as "reset counter to 0"; "reconfigured reference signal" can be understood as "instructed by higher layer to activate reference signal"; and "no longer configured reference signal" can be understood as "instructed by higher layer to update reference signal".

[0014] For example, MAC-CE or downlink control information (DCI) indicates the TCI state, which may allow the reference signal to be reconfigured or deconfigured.

[0015] In conjunction with the first aspect, in some implementations, the method further includes: setting a counter associated with each of the N first beams to 0 when the timer times out or is reconfigured.

[0016] The reconfiguration of the timer can be understood as the timer being set to 0. It should be understood that when the timer is set to 0, the timer returns to the inactive state. Therefore, the counters associated with all new beams (i.e., the N first beams) can be set to 0, causing all new beams to become inactive and ending the current triggering process.

[0017] In this context, timer timeout can be understood as the timer exceeding the time window specified by the timer. When the timer times out, the timer can be set to 0 and all counters associated with the new beams can be set to 0, causing all new beams to fail and ending the current triggering process.

[0018] It should be understood that after the current triggering process ends, the timer and counter can only be restarted when the measured value of the reference signal quality of a new beam satisfies the first relationship again.

[0019] In conjunction with the first aspect, in some implementations, the first relationship includes: the measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold, wherein the second beam is the current TCI. The state-associated beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured value of the reference signal quality of the second beam is less than or equal to a fifth threshold, wherein the fourth threshold is greater than the fifth threshold; or, the measured value of the reference signal quality of L of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a sixth threshold; or, the measured value of the reference signal quality of a certain beam among the N first beams is greater than or equal to a seventh threshold; or, the measured value of the reference signal quality of at least K of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a ninth threshold; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a tenth threshold.

[0020] In this application, the second beam may also be referred to as the current beam.

[0021] The beam associated with the current TCI state can be understood as the beam associated with the TCI state indicated by the current control signaling, such as the TCI state indicated by DCI.

[0022] In conjunction with the first aspect, in some implementations, each of the N first beams is associated with a counter, which increments by a first value each time a count is made. The triggering conditions include: the timer has not timed out, and the sum of the count values ​​of the counters associated with the N first beams is greater than or equal to a second threshold.

[0023] In other words, after each counter count, the count values ​​of all the counters associated with the new beam need to be summed. The triggering condition is considered met when the sum reaches the second threshold and the timer has not expired.

[0024] It should be understood that the first value can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0025] Optionally, the first value can be a fixed value (e.g., a value such as 1, 2, or 3) or a dynamic value (e.g., a value determined based on the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam).

[0026] In conjunction with the first aspect, in some implementations, the first value is determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam.

[0027] For example, the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the larger the corresponding first value can be; the smaller the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the smaller the corresponding first value can be.

[0028] In conjunction with the first aspect, in some implementations, the terminal device includes a correspondence between multiple different difference intervals and multiple different first values. The larger the difference included in the difference interval, the larger the first value corresponding to the difference interval. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0029] Based on this implementation, the greater the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding count value, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0030] For example, multiple different difference intervals may include a first difference interval [a,b), a second difference interval [b,c), a third difference interval [c,d), and so on, where a < b < c < d; the first difference interval [a,b) corresponds to the value 1, the second difference interval [b,c) corresponds to the value 1.5, the third difference interval [c,d) corresponds to the value 2, and so on.

[0031] It should be understood that the difference range can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0032] In conjunction with the first aspect, in some implementations, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. The larger the difference included in the difference interval, the larger the weight corresponding to the difference interval. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments a second value with each count. The triggering conditions include: the timer has not expired, and the value obtained by weighted summation of the count values ​​of all the counters associated with the N first beams and the corresponding weights is greater than or equal to a third threshold.

[0033] For example, each beam can be associated with three counters (counter 1, counter 2, and counter 3). Counter 1 corresponds to the first difference interval [a, b) and weight 10%, counter 2 corresponds to the second difference interval [b, c) and weight 20%, and counter 3 corresponds to the third difference interval [c, d) and weight 30%, where a < b < c < d.

[0034] In other words, after each counter count, the count values ​​of all the counters associated with the new beam need to be summed with their corresponding weights. The triggering condition is considered met when the sum reaches the third threshold and the timer has not expired.

[0035] The second value can be 1, 2, 3, etc., and this application does not limit it.

[0036] It should be understood that the difference range, weight, and second value can be configured or indicated by RRC, MAC CE, or DCI, or can be configured in a predefined manner. This application does not limit this.

[0037] Based on this implementation, the greater the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding weight, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0038] In conjunction with the first aspect, in some implementations, the first relationship includes: the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to an eighth threshold, wherein the second beam is the beam associated with the current TCI state.

[0039] It should be understood that the first relation listed above is only an example, and the actual first relation can also be other relations, which this application does not limit.

[0040] In conjunction with the first aspect, in some implementations, requesting the network device to initiate beam management includes: requesting the network device to initiate beam management based on M beams out of the N first beams, wherein the count value of the counter associated with each of the M beams is greater than or equal to an eleventh threshold.

[0041] In other words, the terminal device can select M beams with count values ​​greater than or equal to the eleventh threshold from the N first beams and report them to the network device to request the network device to start beam management based on the M beams (for example, select one beam from the M beams for beam switching).

[0042] In conjunction with the first aspect, in some implementations, after beam management is completed, the method further includes: setting the timer and the counter associated with each of the N first beams to 0. Based on this, the current triggering process can be terminated.

[0043] In conjunction with the first aspect, in some implementations, the metric for reference signal quality is any one or more of the following: L1-reference signal received power (L1-RSRP), L1-signal to interference plus noise ratio (L1-SINR), reference signal receiving quality (RSRQ), received signal strength indicator (RSSI), and received signal code power (RSCP).

[0044] It should be understood that the reference signal quality listed above is only an example, and the actual reference signal quality may be other, which is not limited in this application.

[0045] Secondly, embodiments of this application provide a method for triggering beam management, which is applied to a network device. This method can be executed by the network device, or by a chip, module, or unit configured within the network device.

[0046] Specifically, the method includes: upon receiving a first message from a terminal device, the first message instructing the terminal device to detect for the first time, without starting a timer, that the measured value of the reference signal quality of a third beam among N first beams satisfies a first relationship, wherein the N first beams are beams not associated with the current TCI state; starting the timer and starting the counter associated with the third beam; sequentially receiving M second messages from the terminal device, each of the M second messages instructing the terminal device to detect, within a time window specified by the timer, that the measured value of the reference signal quality of a certain beam among the N first beams satisfies the first relationship according to a preset period; sequentially updating the counter associated with the corresponding beam based on the M second messages; when detecting that a fourth beam among the N first beams satisfies a target condition, setting the counter associated with the fourth beam to 0; and starting beam management when detecting that the timer timing and the counter associated with the N first beams satisfy a trigger condition.

[0047] Based on this implementation, when the terminal device detects for the first time that the measured value of the reference signal quality of a new beam (e.g., the third beam among N first beams) satisfies the first relationship without the timer being started, it reports the event to the network device. The network device can then start a timer and counter mechanism to determine whether to trigger beam management.

[0048] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0 (e.g., if the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be invalid, and the counter associated with the invalid new beam can be set to 0), so as to avoid the problem of false triggering caused by the invalid new beam triggering beam management, thereby ensuring the stability of signal transmission.

[0049] In conjunction with the second aspect, in some implementations, the target condition includes: the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0050] In conjunction with the second aspect, in some implementations, the method further includes: setting the counters associated with the N first beams to 0 when the timer is detected to have timed out or has been reconfigured.

[0051] In conjunction with the second aspect, in some implementations, the first relationship includes: the measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold, wherein the second beam is the current TCI. The state-associated beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured value of the reference signal quality of the second beam is less than or equal to a fifth threshold, wherein the fourth threshold is greater than the fifth threshold; or, the measured value of the reference signal quality of L of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a sixth threshold; or, the measured value of the reference signal quality of a certain beam among the N first beams is greater than or equal to a seventh threshold; or, the measured value of the reference signal quality of at least K of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a ninth threshold; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a tenth threshold.

[0052] In conjunction with the second aspect, in some implementations, each of the N first beams is associated with a counter, which increments by a first value each time a count is made. The triggering conditions include: the timer has not timed out, and the sum of the count values ​​of the counters associated with the N first beams is greater than or equal to a second threshold.

[0053] In conjunction with the second aspect, in some implementations, the first value is determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam.

[0054] In conjunction with the second aspect, in some implementations, the network device includes a correspondence between multiple different difference intervals and multiple different first values. The larger the difference included in the difference interval, the larger the first value corresponding to the difference interval. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0055] In conjunction with the second aspect, in some implementations, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. The larger the difference included in the difference interval, the larger the weight corresponding to the difference interval. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments a second value with each count. The triggering conditions include: the timer has not timed out, and the value obtained by weighted summation of the count values ​​of all the counters associated with the N first beams and the corresponding weights is greater than or equal to a third threshold.

[0056] In conjunction with the second aspect, in some implementations, the first relationship includes: the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to an eighth threshold, wherein the second beam is the beam associated with the current TCI state.

[0057] In conjunction with the second aspect, in some implementations, the initiation of beam management includes: initiating beam management based on M beams out of the N first beams, wherein the count value of the counter associated with each of the M beams is greater than or equal to the eleventh threshold.

[0058] In conjunction with the second aspect, in some implementations, after beam management is completed, the method further includes: setting the timer and the counter associated with each of the N first beams to 0.

[0059] In conjunction with the second aspect, in some implementations, the metric for the quality of the reference signal is any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP.

[0060] The relevant descriptions and effects of any implementation method in the second aspect are similar to those in the first aspect, and will not be repeated here.

[0061] Thirdly, embodiments of this application provide a method for triggering beam reporting, which is applied to a terminal device. This method can be executed by the terminal device itself, or by a chip, module, or unit configured within the terminal device.

[0062] Specifically, the method includes: when the timer associated with each of the N first beams is not started, and the measured value of the reference signal quality of each of the N first beams is detected sequentially to satisfy a first relationship, the timer and counter associated with each of the N first beams are started sequentially, wherein the N first beams are beams not associated with the current TCI state; the measured value of the reference signal quality of each of the N first beams is detected separately according to a preset period within the time window specified by the timer associated with each of the N first beams; when the measured value of the reference signal quality of a certain beam among the N first beams is detected to satisfy the first relationship, the counter associated with that certain beam is updated; when the fourth beam among the N first beams is detected to satisfy the target condition, the counter associated with the fourth beam is set to 0; when the timer and counter associated with the fifth beam among the N first beams are detected to satisfy the trigger condition, a first message is sent to the network device, the first message being used to request the network device to start beam management.

[0063] It should be noted that the above statement, "when the timers associated with each of the N first beams are not started, and the measured value of the reference signal quality of each of the N first beams is detected to satisfy the first relationship, the timers and counters associated with each of the N first beams are started sequentially," can be understood as: "When the timers associated with each of the N first beams are not started, if the measured value of the reference signal quality of beam 1 is detected to satisfy the first relationship, the timers and counters associated with beam 1 are started first; subsequently, if the measured value of the reference signal quality of beam 2 is detected to satisfy the first relationship, the timers and counters associated with beam 2 are started, and so on."

[0064] It should be noted that the fifth beam among the N first beams can be understood as the beam that first meets the triggering condition. This means that, based on the scheme of this application, the beam that is first triggered to report can be the one associated with the timer and counter among the N first beams.

[0065] Based on this implementation, when the terminal device detects that the measured value of the reference signal quality of a new beam (e.g., a beam among the N first beams) satisfies the first relationship, even if the timers associated with each of the N first beams have not been started, the terminal device can start a timer and counter mechanism to determine whether to trigger beam reporting in order to request the network device to start beam management.

[0066] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0. (For example, if the timer associated with a new beam times out, or the timer associated with a new beam is reconfigured, or the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be faulty, and the counter associated with the faulty new beam can be set to 0.) This avoids the problem of false triggering caused by the faulty new beam triggering beam reporting, thereby ensuring the stability of signal transmission.

[0067] In conjunction with the third aspect, in some implementations, the target condition includes: the timer associated with the fourth beam times out, the timer associated with the fourth beam is reconfigured, the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0068] It should be understood that timer timeout means that the timer has exceeded the time window specified by the timer. When the timer associated with a new beam times out, the timer associated with the new beam and the counter associated with the new beam can be set to 0, so that the new beam becomes invalid.

[0069] It should be understood that reconfiguring a timer can be interpreted as setting the timer to 0. It should also be understood that when a timer associated with a new beam is set to 0, the timer returns to an inactive state. Therefore, the counter associated with the new beam can be set to 0, thus disabling the new beam.

[0070] It should be understood that reconfiguring the counter can be interpreted as setting the counter to 0; reconfiguring the reference signal can be interpreted as the reference signal being instructed to be deactivated by the higher layer; and no longer configuring the reference signal can be interpreted as the reference signal being instructed to be updated by the higher layer.

[0071] For example, MAC-CE or DCI indicating the TCI state can cause the reference signal to be reconfigured or deconfigured.

[0072] It should be understood that if all new beams fail when all new beams meet the target conditions, then the current triggering process can be terminated.

[0073] In conjunction with the third aspect, in some implementations, the first relationship includes: the measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold, wherein the second beam is the current TCI. The state-associated beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured value of the reference signal quality of the second beam is less than or equal to a fifth threshold, wherein the fourth threshold is greater than the fifth threshold; or, the measured value of the reference signal quality of L of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a sixth threshold; or, the measured value of the reference signal quality of a certain beam among the N first beams is greater than or equal to a seventh threshold; or, the measured value of the reference signal quality of at least K of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a ninth threshold; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a tenth threshold.

[0074] In conjunction with the third aspect, in some implementations, each of the N first beams is associated with a counter, and a first value is incremented each time a count is made. The triggering conditions include: the timer associated with the fifth beam has not timed out, and the count value of the counter associated with the fifth beam is greater than or equal to a second threshold.

[0075] In other words, after each count, it is necessary to check whether the count value of a counter associated with a new beam has reached the second threshold. If the count value of a counter associated with a new beam reaches the second threshold and the timer associated with the new beam has not expired, the triggering condition is considered to be met.

[0076] It should be understood that the first value can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0077] Optionally, the first value can be a fixed value (e.g., a value such as 1, 2, or 3) or a dynamic value (e.g., a value determined based on the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam).

[0078] In conjunction with the third aspect, in some implementations, the first value is determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam.

[0079] For example, the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the larger the corresponding first value can be; the smaller the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the smaller the corresponding first value can be.

[0080] In conjunction with the third aspect, in some implementations, the terminal device includes a correspondence between multiple different difference intervals and multiple different first values. The larger the difference included in the difference interval, the larger the first value corresponding to the difference interval. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0081] Based on this implementation, the greater the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding count value, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0082] For example, multiple different difference intervals may include a first difference interval [a,b), a second difference interval [b,c), a third difference interval [c,d), and so on, where a < b < c < d; the first difference interval [a,b) corresponds to the value 1, the second difference interval [b,c) corresponds to the value 1.5, the third difference interval [c,d) corresponds to the value 2, and so on.

[0083] It should be understood that the difference range can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0084] In conjunction with the third aspect, in some implementations, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. The larger the difference included in the difference interval, the larger the weight corresponding to the difference interval. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments a second value with each count. The triggering conditions include: the timer associated with the fifth beam has not timed out, and the value obtained by multiplying the count value of the first counter among the multiple counters associated with the fifth beam with the corresponding weight is greater than or equal to a third threshold.

[0085] For example, each beam can be associated with three counters (counter 1, counter 2, and counter 3). Counter 1 corresponds to the first difference interval [a, b) and weight 10%, counter 2 corresponds to the second difference interval [b, c) and weight 20%, and counter 3 corresponds to the third difference interval [c, d) and weight 30%, where a < b < c < d.

[0086] In other words, after each count by a counter associated with a new beam, the count value of the counter needs to be multiplied by the corresponding weight. If the value obtained after multiplication is greater than or equal to the third threshold and the timer associated with the new beam has not timed out, the triggering condition is considered to be met.

[0087] The second value can be 1, 2, 3, etc., and this application does not limit it.

[0088] It should be understood that the difference range, weight, and second value can be configured or indicated by RRC, MAC CE, or DCI, or can be configured in a predefined manner. This application does not limit this.

[0089] Based on this implementation, the greater the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding weight, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0090] In conjunction with the third aspect, in some implementations, the first relationship includes: the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to an eighth threshold, wherein the second beam is the beam associated with the current TCI state.

[0091] It should be understood that the first relation listed above is only an example, and the actual first relation can also be other relations, which this application does not limit.

[0092] In conjunction with the third aspect, in some implementations, the initiation beam management includes: switching the second beam to the fifth beam, the second beam being the beam associated with the current TCI state.

[0093] In conjunction with the third aspect, in some implementations, after beam management is completed, the method further includes: setting the timer and counter associated with each of the N first beams to 0. Based on this, the current triggering process can be terminated.

[0094] In conjunction with the third aspect, in some implementations, the metric for the quality of the reference signal is any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP.

[0095] Fourthly, embodiments of this application provide a method for triggering beam management, which is applied to a network device. This method can be executed by the network device, or by a chip, module, or unit configured within the network device.

[0096] Specifically, the method includes: upon sequentially receiving N first messages sent by a terminal device, the N first messages instructing the terminal device to sequentially detect that the measured value of the reference signal quality of each of the N first beams satisfies a first relationship when the timer associated with each of the N first beams is not started, wherein the N first beams are beams not associated with the current TCI state; sequentially starting the timer and counter associated with each of the N first beams; sequentially receiving M second messages sent by the terminal device, each of the M second messages instructing the terminal device to detect that the measured value of the reference signal quality of a certain beam satisfies the first relationship within a time window specified by the timer associated with a certain beam of the N first beams according to a preset period; sequentially updating the counter associated with the corresponding beam based on the M second messages; when the fourth beam of the N first beams is detected to meet the target condition, setting the counter associated with the fourth beam to 0; and when the timer and counter associated with the fifth beam of the N first beams are detected to meet the trigger condition, starting beam management.

[0097] It should be noted that the above statement, "When receiving N first messages from the terminal device in sequence, the N first messages are used to instruct the terminal device to sequentially detect that the measured value of the reference signal quality of each of the N first beams satisfies the first relationship when the timer associated with each of the N first beams is not started, and to sequentially start the timer and counter associated with each of the N first beams," can be understood as follows: "When the timer associated with each of the N first beams is not started, if the terminal device detects that the measured value of the reference signal quality of beam 1 satisfies the first relationship, it first sends a message to the network device to report the event, so that the network device can start the timer and counter associated with beam 1; subsequently, if the terminal device detects that the measured value of the reference signal quality of beam 2 satisfies the first relationship, it sends another message to the network device to report the event, so that the network device can start the timer and counter associated with beam 2 again, and so on."

[0098] It should be noted that the fifth beam among the N first beams can be understood as the beam that first meets the triggering condition. This means that, based on the scheme of this application, the beam that is first triggered to report can be the one associated with the timer and counter among the N first beams.

[0099] Based on this implementation, when the terminal device detects that the measured value of the reference signal quality of a new beam (e.g., a beam among the N first beams) satisfies the first relationship, even if the timers associated with each of the N first beams have not been started, the terminal device can report the event to the network device, so that the network device can start a timer and counter mechanism to determine whether beam management is triggered.

[0100] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0. (For example, if the timer associated with a new beam times out, or the timer associated with a new beam is reconfigured, or the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be faulty, and the counter associated with the faulty new beam can be set to 0.) This avoids the problem of false triggering caused by the faulty new beam triggering beam reporting, thereby ensuring the stability of signal transmission.

[0101] In conjunction with the fourth aspect, in some implementations, the target condition includes: the timer associated with the fourth beam times out, the timer associated with the fourth beam is reconfigured, the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0102] In conjunction with the fourth aspect, in some implementations, the first relationship includes: the measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold, wherein the second beam is the current TCI. The state-associated beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured value of the reference signal quality of the second beam is less than or equal to a fifth threshold, wherein the fourth threshold is greater than the fifth threshold; or, the measured value of the reference signal quality of L of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a sixth threshold; or, the measured value of the reference signal quality of a certain beam among the N first beams is greater than or equal to a seventh threshold; or, the measured value of the reference signal quality of at least K of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a ninth threshold; or, the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value among the measured values ​​of the reference signal quality corresponding to the activated transmission configuration indication state and a tenth threshold.

[0103] In conjunction with the fourth aspect, in some implementations, each of the N first beams is associated with a counter, and a first value is incremented each time a count is made. The triggering conditions include: the timer associated with the fifth beam has not timed out, and the count value of the counter associated with the fifth beam is greater than or equal to a second threshold.

[0104] In conjunction with the fourth aspect, in some implementations, the first value is determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam.

[0105] In conjunction with the fourth aspect, in some implementations, the network device includes a correspondence between multiple different difference intervals and multiple different first values. The larger the difference included in the difference interval, the larger the first value corresponding to the difference interval. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0106] In conjunction with the fourth aspect, in some implementations, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. The larger the difference included in the difference interval, the larger the weight corresponding to the difference interval. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments a second value with each count. The triggering conditions include: the timer associated with the fifth beam has not timed out, and the value obtained by multiplying the count value of the first counter among the multiple counters associated with the third beam with the corresponding weight is greater than or equal to a third threshold.

[0107] In conjunction with the fourth aspect, in some implementations, the first relationship includes: the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to an eighth threshold, wherein the second beam is the beam associated with the current TCI state.

[0108] In conjunction with the fourth aspect, in some implementations, the initiation beam management includes switching the second beam to the fifth beam, the second beam being the beam associated with the current TCI state.

[0109] In conjunction with the fourth aspect, in some implementations, after beam management is completed, the method further includes: setting the timer and counter associated with each of the N first beams to 0.

[0110] In conjunction with the fourth aspect, in some implementations, the metric for reference signal quality is any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP.

[0111] The relevant descriptions and effects of any implementation method in this fourth aspect are similar to those in the third aspect, and will not be repeated here.

[0140] To facilitate understanding of the embodiments of this application, the following points will be explained before introducing the embodiments of this application.

[0141] First, in the embodiments of this application, "for indicating" can include both direct and indirect indication. For example, when describing a certain indication information as indicating information I, it can include whether the indication information directly indicates I or indirectly indicates I, but does not necessarily mean that the indication information carries I.

[0142] Second, in the embodiments shown below, the terms "first," "second," and various numerical designations are merely distinctions for ease of description and are not intended to limit the scope of the embodiments of this application.

[0143] Third, it should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0144] Fourth, "at least one" means one or more, while "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Here, a, b, and c can be single or multiple.

[0145] The technical solutions of this application embodiment can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, future 5th Generation (5G) system, or New Radio (NR), etc.

[0146] To facilitate understanding of the embodiments of this application, let's first take... Figure 1 The communication system shown in the figure is used as an example to describe in detail the communication system applicable to the embodiments of this application. Figure 1 This is a schematic diagram of a communication system 100 applicable to the method of triggering beam management in embodiments of this application. Figure 1 As shown, the communication system 100 may include at least one network device, such as Figure 1 The network device 110 shown; the communication system 100 may also include at least one terminal device, such as Figure 1 The terminal device 120 is shown. Network device 110 and terminal device 120 can communicate via a wireless link. Each communication device, such as network device 110 or terminal device 120, can be configured with multiple antennas. For each communication device in the communication system 100, the configured multiple antennas may include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. Therefore, the communication devices in the communication system 100, such as network device 110 and terminal device 120, can communicate via multi-antenna technology.

[0147] It should be understood that the network equipment in this communication system can be any device with wireless transceiver capabilities. The network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in a wireless fidelity (WiFi) system. It can also be a gNB in ​​a 5G system, such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0148] In some deployments, a gNB may include a centralized unit (CU) and a DU. A gNB may also include a radio unit (RU). The CU implements some of the gNB's functions, and the DU implements some of its functions. For example, the CU implements the functions of the RRC (Relative Data Convergence Protocol) layer, while the DU implements the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+CU. It is understood that network devices can be CU nodes, DU nodes, or devices including both CU and DU nodes. Furthermore, the CU can be classified as a network device in the radio access network (RAN), or as a network device in the core network (CN); this application does not limit this classification.

[0149] It should also be understood that the terminal equipment in this communication system can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. In the embodiments of this application, the terminal equipment can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal equipment, augmented reality (AR) terminal equipment, wireless terminal in industrial control, 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, etc.

[0150] It should also be understood that Figure 1 This is a simplified illustration for ease of understanding only. The communication system 100 may also include other network devices or other terminal devices. Figure 1 It was not drawn in the middle.

[0151] In communication technology, terminal devices typically need to communicate with network devices based on beams, and the quality of the beam's reference signal usually affects the stability of signal transmission. Current protocols propose that when the measured values ​​of the reference signal quality of a new beam meet a certain relationship, beam reporting or beam management can be triggered to switch the current beam to a new beam with better quality. However, based on current technology, when the measured values ​​of the reference signal quality of a new beam are detected to meet a certain relationship, there is a lack of a mechanism to determine whether to trigger beam reporting or beam management.

[0152] Based on this, this application proposes that when a terminal device detects for the first time that the measured value of the reference signal quality of a new beam meets a certain relationship, it can start a preset timer and counter mechanism through the terminal device or network device to determine whether to trigger beam reporting or beam management. In addition, during the counter counting process, the counter associated with the failed new beam that meets the target condition can be set to 0 to avoid false triggering of the failed new beam, thereby ensuring the stability of signal transmission.

[0153] The following will describe in detail the method for triggering beam reporting or beam management provided in the embodiments of this application, using the following four implementation methods (i.e., implementation method 1 to implementation method 4).

[0154] It should be understood that each of the following implementation methods 1 to 4 can be applied to systems that communicate using multi-antenna technology, for example, Figure 1 The communication system 100 shown herein may include at least one network device and at least one terminal device. The network device and the terminal device may communicate via multi-antenna technology.

[0155] It should also be understood that the embodiments shown below do not particularly limit the specific structure of the execution subject of the method provided in the embodiments of this application. As long as it is possible to communicate according to the method provided in the embodiments of this application by running a program that records the code of the method provided in the embodiments of this application, for example, the execution subject of the method provided in the embodiments of this application can be a terminal device or a network device, or a functional module in a terminal device or network device that can call and execute a program.

[0156] Without loss of generality, the beam reporting or beam management provided in the embodiments of this application will be described in detail using the interaction between network devices and terminal devices as an example.

[0157] Figure 2 This is a schematic flowchart (i.e., implementation method 1) of a method for triggering beam reporting provided in an embodiment of this application. Figure 2As shown, method 200 may include steps 210 to 260, and each step of the method is described in detail below. It should be understood that in this implementation, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0158] S210, when the terminal device detects for the first time that the measured value of the reference signal quality of the third beam among the N first beams satisfies the first relationship without the timer being started, it starts the timer and the counter associated with the third beam. Here, N is an integer greater than or equal to 1.

[0159] It should be understood that each of the N first beams involved in this application may also be referred to as a new beam; the second beam may also be referred to as a current beam.

[0160] Among them, the N first beams are beams not associated with the current TCI state. The beams not associated with the current TCI state can be understood as beams associated with TCI states configured by RRC or MAC CE, or beams corresponding to reference signals configured by downlink signaling; the second beams are beams associated with the current TCI state. The beams associated with the current TCI state can be understood as beams associated with the TCI state indicated by the current control signaling, such as the TCI state indicated by DCI.

[0161] It should be understood that in this implementation, N first beams are associated with one timer; each of the N first beams can be associated with one timer or multiple timers.

[0162] Optionally, the first relationship mentioned above can be any of the following:

[0163] Example 1: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold.

[0164] The specific values ​​of the thresholds involved in this implementation (e.g., any one or more of the first threshold to the eleventh threshold) can be configured or indicated by RRC, MAC CE or DCI, or can be configured in a predefined way. This application does not limit this.

[0165] Example 2: The measured reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured reference signal quality of the second beam is less than or equal to a fifth threshold. Wherein, the fourth threshold is greater than the fifth threshold.

[0166] Example 3: The measured values ​​of the reference signal quality of L of the N first beams are greater than or equal to the sum of the measured values ​​of the reference signal quality of the second beam and the sixth threshold.

[0167] Example 4: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the seventh threshold.

[0168] Example 5, the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to the eighth threshold.

[0169] Example 6: The measured reference signal quality of at least K of the N first beams is greater than or equal to the measured reference signal quality of the second beam.

[0170] Example 7: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the ninth threshold.

[0171] Example 8: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the tenth threshold.

[0172] It should be understood that the first relation listed above is only an example, and the actual first relation can also be other relations, which this application does not limit.

[0173] Optionally, the metric for the reference signal quality can be any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP. It should be understood that the reference signal qualities listed above are merely examples, and the actual reference signal quality can be other than those listed herein; this application does not limit the specific reference signal quality.

[0174] S220, the terminal device detects the reference signal quality of each of the N first beams according to a preset rule within the time window specified by the timer.

[0175] It should be understood that when the measurement value of the reference signal quality of the second beam, which is included in the first relationship, needs to meet certain conditions, the measurement value of the reference signal quality of the second beam also needs to be detected when the measurement value of the reference signal quality of each of the N first beams is detected according to a preset rule within the time window specified by the timer.

[0176] S230, when the terminal device detects that the measured value of the reference signal quality of a certain beam among the N first beams satisfies the first relationship, it updates the counter associated with that beam.

[0177] It should be understood that the measured value of the reference signal quality of the beam will change over time. Therefore, within the time window specified by the timer, the measured value of the reference signal quality of each beam needs to be continuously detected according to a preset rule, and the counter is updated based on the latest measured value of the detected reference signal quality.

[0178] In one possible implementation, each of the N first beams is associated with a counter, and the first value is incremented each time a count is performed.

[0179] It should be understood that the first value can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0180] Optionally, the first value can be a fixed value (e.g., a value such as 1, 2, or 3) or a dynamic value (e.g., the first value can be determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam).

[0181] For example, the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the larger the corresponding first value can be; the smaller the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the smaller the corresponding first value can be.

[0182] Optionally, the terminal device may include a correspondence between multiple different difference intervals and multiple different first values. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0183] Optionally, the larger the difference included in the difference interval, the larger the first value corresponding to the difference interval can be. For example, multiple different difference intervals may include a first difference interval [a,b), a second difference interval [b,c), a third difference interval [c,d), and so on, where a < b < c < d; the first difference interval [a,b) corresponds to the value 1, the second difference interval [b,c) corresponds to the value 1.5, the third difference interval [c,d) corresponds to the value 2, and so on. This allows for certain scenarios (e.g., when the first relationship is Example 1; or, when the first relationship is Example 2 and the fourth threshold is greater than the fifth threshold; or, when the first relationship is Example 3; or, when the first relationship is Example 4 and the measured value of the reference signal quality of one of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, when the first relationship is Example 6; or, when the first relationship is Example 7 and the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, when the first relationship is Example 8 and the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; etc.), where the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding count value, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0184] It should be understood that the difference range involved in this implementation can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0185] Optionally, the larger the difference included in the difference range, the smaller the first value corresponding to the difference range can be. This needs to be determined in combination with the specific circumstances of the first relationship, and this application does not limit it.

[0186] In another possible implementation, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments by a second value each time a count is performed.

[0187] Optionally, the larger the difference included in the difference interval, the larger the weight corresponding to the difference interval can be. For example, each beam can be associated with 3 counters (counter 1, counter 2, and counter 3), counter 1 corresponds to the first difference interval [a, b) and weight 10%, counter 2 corresponds to the second difference interval [b, c) and weight 20%, and counter 3 corresponds to the third difference interval [c, d) and weight 30%, where a < b < c < d. This allows for certain scenarios (e.g., when the first relationship is Example 1; or, when the first relationship is Example 2 and the fourth threshold is greater than the fifth threshold; or, when the first relationship is Example 3; or, when the first relationship is Example 4 and the measured value of the reference signal quality of one of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, when the first relationship is Example 6; or, when the first relationship is Example 7 and the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; or, when the first relationship is Example 8 and the measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the measured value of the reference signal quality of the second beam; etc.), where the greater the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding weight, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0188] Optionally, the larger the difference included in the difference interval, the smaller the weight corresponding to the difference interval can be. This needs to be determined in combination with the specific circumstances of the first relationship, and this application does not impose any restrictions on this.

[0189] The second value can be 1, 2, 3, etc., and this application does not limit it.

[0190] It should be understood that the difference range, weight, and second value can be configured or indicated by RRC, MAC CE, or DCI, or can be configured in a predefined manner. This application does not limit this.

[0191] S240, when the terminal device detects that the fourth beam among the N first beams meets the target condition, it sets the counter associated with the fourth beam to 0.

[0192] Optionally, the target condition may include any one of the following: the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0193] Here, reconfiguring the counter can be understood as setting the counter to 0; reconfiguring the reference signal can be understood as the reference signal being deactivated by an instruction from a higher layer; and deconfiguring the reference signal can be understood as the reference signal being updated by an instruction from a higher layer. For example, MAC-CE or DCI indicating TCI state can cause the reference signal to be reconfigured or deconfigured.

[0194] Optionally, when a timer timeout is detected or the timer is reconfigured, the counter associated with each of the N first beams can be set to 0.

[0195] The reconfiguration of the timer can be understood as the timer being set to 0. It should be understood that when the timer is set to 0, the timer returns to the inactive state. Therefore, the counters associated with all new beams (i.e., the N first beams) can be set to 0, causing all new beams to become inactive and ending the current triggering process.

[0196] In this context, timer timeout can be understood as the timer exceeding the time window specified by the timer. When the timer times out, the timer can be set to 0 and all counters associated with the new beams can be set to 0, causing all new beams to fail and ending the current triggering process.

[0197] It should be understood that after the current triggering process ends, the timer and counter can only be restarted when the measured value of the reference signal quality of a new beam satisfies the first relationship again.

[0198] S250, when the terminal device detects that the timer count and the counts of the counters associated with the N first beams meet the trigger condition, it sends a first message to the network device. Correspondingly, the network device receives the first message sent by the terminal device.

[0199] The first message is used to request the network device to initiate beam management. This request includes requesting the network device to initiate beam management based on M of the N first beams, where the count value of the counter associated with each of the M beams is greater than or equal to an eleventh threshold.

[0200] In other words, the terminal device can select M beams with count values ​​greater than or equal to the eleventh threshold from the N first beams and report them to the network device to request the network device to start beam management based on the M beams (for example, select one beam from the M beams for beam switching).

[0201] Optionally, if a counter is associated with each of the N first beams and a first value is incremented each time a count is made, the triggering condition may include: the timer has not timed out and the sum of the count values ​​of the counters associated with the N first beams is greater than or equal to a second threshold.

[0202] In other words, after each counter count, the count values ​​of all the counters associated with the new beam need to be summed. The triggering condition is considered met when the sum reaches the second threshold and the timer has not expired.

[0203] Optionally, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and a second value is incremented each time the count is performed. The triggering condition may include: the timer has not expired, and the value obtained by weighted summation of the count values ​​of all the counters associated with the N first beams and the corresponding weights is greater than or equal to a third threshold.

[0204] In other words, after each counter count, the count values ​​of all the counters associated with the new beam need to be summed with their corresponding weights. The triggering condition is considered met when the sum reaches the third threshold and the timer has not expired.

[0205] S260, Network device initiates beam management.

[0206] Optionally, after beam management is complete, the terminal device can set the timer and the counter associated with each of the N first beams to 0. Based on this, the current triggering process ends.

[0207] Based on this implementation, when the terminal device detects for the first time that the measured value of the reference signal quality of a new beam (e.g., the third beam among N first beams) satisfies the first relationship without the timer being started, it can start a timer and counter mechanism to determine whether to trigger beam reporting in order to request the network device to start beam management.

[0208] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0 (e.g., if the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be invalid, and the counter associated with the invalid new beam can be set to 0). This avoids the problem of false triggering caused by the invalid new beam triggering beam reporting, thereby ensuring the stability of signal transmission.

[0209] Figure 3 This is a schematic flowchart (i.e., implementation 2) of a method for triggering beam management provided in an embodiment of this application. Figure 3As shown, method 300 may include steps 310 to 350, and each step of the method is described in detail below. It should be understood that in this implementation, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0210] S310: When the network device receives the first message sent by the terminal device, it starts a timer to start counting and starts a counter associated with the third beam to start counting.

[0211] The first message indicates that the terminal device, without starting the timer, detects for the first time that the measured value of the reference signal quality of the third beam out of N first beams satisfies the first relationship. Here, N is an integer greater than or equal to 1.

[0212] It should be understood that the introduction of the N first beams and second beams involved in this implementation method can be found above, and will not be repeated here.

[0213] It should be understood that in this implementation, N first beams are associated with one timer; each of the N first beams can be associated with one timer or multiple timers.

[0214] Optionally, the first relationship mentioned above can be any of the following:

[0215] Example 1: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold.

[0216] The specific values ​​of the thresholds involved in this implementation (e.g., any one or more of the first threshold to the eleventh threshold) can be configured or indicated by RRC, MAC CE or DCI, or can be configured in a predefined way. This application does not limit this.

[0217] Example 2: The measured reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured reference signal quality of the second beam is less than or equal to a fifth threshold. Wherein, the fourth threshold is greater than the fifth threshold.

[0218] Example 3: The measured values ​​of the reference signal quality of L of the N first beams are greater than or equal to the sum of the measured values ​​of the reference signal quality of the second beam and the sixth threshold.

[0219] Example 4: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the seventh threshold.

[0220] Example 5, the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to the eighth threshold.

[0221] Example 6: The measured reference signal quality of at least K of the N first beams is greater than or equal to the measured reference signal quality of the second beam.

[0222] Example 7: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the ninth threshold.

[0223] Example 8: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the tenth threshold.

[0224] It should be understood that the first relation listed above is only an example, and the actual first relation can also be other relations, which this application does not limit.

[0225] Optionally, the metric for the reference signal quality can be any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP. It should be understood that the reference signal qualities listed above are merely examples, and the actual reference signal quality can be other than those listed herein; this application does not limit the specific reference signal quality.

[0226] S320, the terminal device sequentially sends M second messages to the network device. Correspondingly, the network device sequentially receives the M second messages sent by the terminal device.

[0227] Each of the M second messages is used to instruct the terminal device to detect, within the time window specified by the timer, that the measured value of the reference signal quality of a certain beam among the N first beams satisfies the first relationship according to the preset period.

[0228] S330, the network device updates the counter associated with the corresponding beam sequentially based on M second messages.

[0229] It should be understood that the measured value of the reference signal quality of the beam will change over time. Therefore, within the time window specified by the timer, the measured value of the reference signal quality of each beam needs to be continuously detected according to a preset rule, and the counter is updated based on the latest measured value of the detected reference signal quality.

[0230] In one possible implementation, each of the N first beams is associated with a counter, and the first value is incremented each time a count is performed.

[0231] It should be understood that the first value can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0232] Optionally, the first value can be a fixed value (e.g., a value such as 1, 2, or 3) or a dynamic value (e.g., the first value can be determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam).

[0233] For example, the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the larger the corresponding first value can be; the smaller the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the smaller the corresponding first value can be.

[0234] Optionally, the network device may include a correspondence between multiple different difference intervals and multiple different first values. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0235] Optionally, the larger the difference included in the difference interval, the larger the first value corresponding to the difference interval can be. For example, multiple different difference intervals may include a first difference interval [a,b), a second difference interval [b,c), a third difference interval [c,d), and so on, where a < b < c < d; the first difference interval [a,b) corresponds to the value 1, the second difference interval [b,c) corresponds to the value 1.5, the third difference interval [c,d) corresponds to the value 2, and so on. This makes it possible that in certain scenarios (for example, when the first relationship is Example 1; other scenarios can be found above and will not be repeated), the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding count value, thus reaching the trigger condition faster and improving the efficiency of beam reporting.

[0236] It should be understood that the difference range can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0237] Optionally, the larger the difference included in the difference range, the smaller the first value corresponding to the difference range can be. This needs to be determined in combination with the specific circumstances of the first relationship, and this application does not limit it.

[0238] In another possible implementation, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments by a second value each time a count is performed.

[0239] Optionally, the larger the difference included in the difference interval, the larger the weight corresponding to the difference interval can be. For example, each beam can be associated with three counters (counter 1, counter 2, and counter 3). Counter 1 corresponds to the first difference interval [a, b) and a weight of 10%, counter 2 corresponds to the second difference interval [b, c) and a weight of 20%, and counter 3 corresponds to the third difference interval [c, d) and a weight of 30%, where a < b < c < d. This makes it possible that in certain scenarios (e.g., when the first relationship is as in Example 1; other scenarios can be found above and will not be repeated here), the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding weight, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0240] Optionally, the larger the difference included in the difference interval, the smaller the weight corresponding to the difference interval can be. This needs to be determined in combination with the specific circumstances of the first relationship, and this application does not impose any restrictions on this.

[0241] The second value can be 1, 2, 3, etc., and this application does not limit it.

[0242] It should be understood that the difference range, weight, and second value can be configured or indicated by RRC, MAC CE, or DCI, or can be configured in a predefined manner. This application does not limit this.

[0243] S340, when the network device detects that the fourth beam among the N first beams meets the target condition, it sets the counter associated with the fourth beam to 0.

[0244] Optionally, the target condition may include any one of the following: the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0245] Here, reconfiguring the counter can be understood as setting the counter to 0; reconfiguring the reference signal can be understood as the reference signal being deactivated by an instruction from a higher layer; and deconfiguring the reference signal can be understood as the reference signal being updated by an instruction from a higher layer. For example, MAC-CE or DCI indicating TCI state can cause the reference signal to be reconfigured or deconfigured.

[0246] Optionally, when a timer timeout is detected or the timer is reconfigured, the counter associated with each of the N first beams can be set to 0.

[0247] The reconfiguration of the timer can be understood as the timer being set to 0. It should be understood that when the timer is set to 0, the timer returns to the inactive state. Therefore, the counters associated with all new beams (i.e., the N first beams) can be set to 0, causing all new beams to become inactive and ending the current triggering process.

[0248] In this context, timer timeout can be understood as the timer exceeding the time window specified by the timer. When the timer times out, the timer can be set to 0 and all counters associated with the new beams can be set to 0, causing all new beams to fail and ending the current triggering process.

[0249] It should be understood that after the current triggering process ends, the timer and counter can only be restarted when the measured value of the reference signal quality of a new beam satisfies the first relationship again.

[0250] S350: When the network device detects that the timer count and the counts of the N first beams associated with the counter meet the trigger conditions, beam management is initiated.

[0251] Optionally, the beam management initiation includes: initiating beam management based on M beams out of the N first beams, wherein the count value of the counter associated with each of the M beams is greater than or equal to an eleventh threshold. That is, the network device can select M beams with count values ​​greater than or equal to the eleventh threshold from the N first beams to initiate beam management (e.g., selecting one beam from the M beams for beam switching).

[0252] Optionally, if a counter is associated with each of the N first beams and a first value is incremented each time a count is made, the triggering condition may include: the timer has not timed out and the sum of the count values ​​of the counters associated with the N first beams is greater than or equal to a second threshold.

[0253] In other words, after each counter count, the count values ​​of all the counters associated with the new beam need to be summed. The triggering condition is considered met when the sum reaches the second threshold and the timer has not expired.

[0254] Optionally, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and a second value is incremented each time the count is performed. The triggering condition may include: the timer has not expired, and the value obtained by weighted summation of the count values ​​of all the counters associated with the N first beams and the corresponding weights is greater than or equal to a third threshold.

[0255] In other words, after each counter count, the count values ​​of all the counters associated with the new beam need to be summed with their corresponding weights. The triggering condition is considered met when the sum reaches the third threshold and the timer has not expired.

[0256] Optionally, after beam management is complete, the network device can set the timer and the counter associated with each of the N first beams to 0. Based on this, the current triggering process ends.

[0257] Based on this implementation, when the terminal device detects for the first time that the measured value of the reference signal quality of a new beam (e.g., the third beam among N first beams) satisfies the first relationship without the timer being started, it reports the event to the network device. The network device can then start a timer and counter mechanism to determine whether to trigger beam management.

[0258] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0 (e.g., if the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be invalid, and the counter associated with the invalid new beam can be set to 0), so as to avoid the problem of false triggering caused by the invalid new beam triggering beam management, thereby ensuring the stability of signal transmission.

[0259] Figure 4 This is a schematic flowchart of another method for triggering beam reporting provided in this application (i.e., implementation method 3). For example... Figure 4 As shown, the method 400 may include steps 410 to 460, and each step of the method is described in detail below. It should be understood that in this implementation, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0260] S410, when the terminal device sequentially detects that the measured value of the reference signal quality of each of the N first beams satisfies the first relationship without the timer associated with each of the N first beams being started, it sequentially starts the timer and counter associated with each of the N first beams. Here, N is an integer greater than or equal to 1.

[0261] It should be understood that the introduction of the N first beams and second beams involved in this implementation method can be found above, and will not be repeated here.

[0262] It should be noted that the above statement, "when the timers associated with each of the N first beams are not started, and the measured value of the reference signal quality of each of the N first beams is detected to satisfy the first relationship, the timers and counters associated with each of the N first beams are started sequentially," can be understood as: "When the timers associated with each of the N first beams are not started, if the measured value of the reference signal quality of beam 1 is detected to satisfy the first relationship, the timers and counters associated with beam 1 are started first; subsequently, if the measured value of the reference signal quality of beam 2 is detected to satisfy the first relationship, the timers and counters associated with beam 2 are started, and so on."

[0263] It should be understood that in this implementation, each of the N first beams is associated with a timer; each of the N first beams can be associated with one timer or multiple timers.

[0264] Optionally, the first relationship mentioned above can be any of the following:

[0265] Example 1: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold.

[0266] The specific values ​​of the thresholds involved in this implementation (e.g., any one or more of the first threshold to the eleventh threshold) can be configured or indicated by RRC, MAC CE or DCI, or can be configured in a predefined way. This application does not limit this.

[0267] Example 2: The measured reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured reference signal quality of the second beam is less than or equal to a fifth threshold. Wherein, the fourth threshold is greater than the fifth threshold.

[0268] Example 3: The measured values ​​of the reference signal quality of L of the N first beams are greater than or equal to the sum of the measured values ​​of the reference signal quality of the second beam and the sixth threshold.

[0269] Example 4: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the seventh threshold.

[0270] Example 5, the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to the eighth threshold.

[0271] Example 6: The measured reference signal quality of at least K of the N first beams is greater than or equal to the measured reference signal quality of the second beam.

[0272] Example 7: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the ninth threshold.

[0273] Example 8: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the tenth threshold.

[0274] It should be understood that the first relation listed above is only an example, and the actual first relation can also be other relations, which this application does not limit.

[0275] Optionally, the metric for the reference signal quality can be any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP. It should be understood that the reference signal qualities listed above are merely examples, and the actual reference signal quality can be other than those listed herein; this application does not limit the specific reference signal quality.

[0276] S420, the terminal device detects the reference signal quality of each of the N first beams according to a preset period within a time window specified by a timer associated with each of the N first beams.

[0277] It should be understood that when the measurement value of the reference signal quality of the second beam, which is included in the first relationship, needs to meet certain conditions, the measurement value of the reference signal quality of the second beam also needs to be detected when the time window associated with each of the N first beams is specified according to a preset period.

[0278] S430, when the terminal device detects that the measured value of the reference signal quality of a certain beam among the N first beams satisfies the first relationship, it updates the counter associated with that beam.

[0279] It should be understood that the measured value of the reference signal quality of the beam will change over time. Therefore, within the time window specified by the timer, the measured value of the reference signal quality of each beam needs to be continuously detected according to a preset rule, and the counter is updated based on the latest measured value of the detected reference signal quality.

[0280] In one possible implementation, each of the N first beams is associated with a counter, and the first value is incremented each time a count is performed.

[0281] It should be understood that the first value can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0282] Optionally, the first value can be a fixed value (e.g., a value such as 1, 2, or 3) or a dynamic value (e.g., the first value can be determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam).

[0283] For example, the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the larger the corresponding first value can be; the smaller the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the smaller the corresponding first value can be.

[0284] Optionally, the terminal device may include a correspondence between multiple different difference intervals and multiple different first values. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0285] Optionally, the larger the difference included in the difference interval, the larger the first value corresponding to the difference interval can be. For example, multiple different difference intervals may include a first difference interval [a,b), a second difference interval [b,c), a third difference interval [c,d), and so on, where a < b < c < d; the first difference interval [a,b) corresponds to the value 1, the second difference interval [b,c) corresponds to the value 1.5, the third difference interval [c,d) corresponds to the value 2, and so on. This makes it possible that in certain scenarios (for example, when the first relationship is Example 1; other scenarios can be found above and will not be repeated), the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding count value, thus reaching the trigger condition faster and improving the efficiency of beam reporting.

[0286] It should be understood that the difference range can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0287] In another possible implementation, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments by a second value each time a count is performed.

[0288] Optionally, the larger the difference included in the difference interval, the larger the weight corresponding to the difference interval can be. For example, each beam can be associated with three counters (counter 1, counter 2, and counter 3). Counter 1 corresponds to the first difference interval [a, b) and a weight of 10%, counter 2 corresponds to the second difference interval [b, c) and a weight of 20%, and counter 3 corresponds to the third difference interval [c, d) and a weight of 30%, where a < b < c < d. This makes it possible that in certain scenarios (e.g., when the first relationship is as in Example 1; other scenarios can be found above and will not be repeated here), the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding weight, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0289] Optionally, the larger the difference included in the difference interval, the smaller the weight corresponding to the difference interval can be. This needs to be determined in combination with the specific circumstances of the first relationship, and this application does not impose any restrictions on this.

[0290] The second value can be 1, 2, 3, etc., and this application does not limit it.

[0291] It should be understood that the difference range, weight, and second value can be configured or indicated by RRC, MAC CE, or DCI, or can be configured in a predefined manner. This application does not limit this.

[0292] S440, when the terminal device detects that the fourth beam among the N first beams meets the target condition, it sets the counter associated with the fourth beam to 0.

[0293] The target conditions include: the timer associated with the fourth beam times out, the timer associated with the fourth beam is reconfigured, the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0294] It should be understood that timer timeout means that the timer has exceeded the time window specified by the timer. When the timer associated with a new beam times out, the timer associated with the new beam and the counter associated with the new beam can be set to 0, so that the new beam becomes invalid.

[0295] It should be understood that reconfiguring a timer can be interpreted as setting the timer to 0. It should also be understood that when a timer associated with a new beam is set to 0, the timer returns to an inactive state. Therefore, the counter associated with the new beam can be set to 0, thus disabling the new beam.

[0296] It should be understood that reconfiguring the counter can be interpreted as setting the counter to 0; reconfiguring the reference signal can be interpreted as the reference signal being instructed to be deactivated by the higher layer; and no longer configuring the reference signal can be interpreted as the reference signal being instructed to be updated by the higher layer.

[0297] For example, MAC-CE or DCI indicating the TCI state can cause the reference signal to be reconfigured or deconfigured.

[0298] It should be understood that if all new beams fail when all new beams meet the target conditions, the current triggering process can be terminated. It should also be understood that after the current triggering process ends, the timer and counter can only be restarted when the measured value of the reference signal quality of a new beam again satisfies the first relationship.

[0299] S450, when the terminal device detects that the timer and counter associated with the fifth beam out of the N first beams meet the trigger conditions, it sends a first message to the network device. Correspondingly, the network device receives the first message sent by the terminal device.

[0300] The first message is used to request the network device to start beam management.

[0301] It should be noted that the fifth beam among the N first beams can be understood as the beam that first meets the triggering condition. This means that, based on the scheme of this application, the beam that is first triggered to report can be the one associated with the timer and counter among the N first beams.

[0302] Optionally, if each of the N first beams is associated with a counter, and a first value is incremented with each count, the triggering condition may include: the timer associated with the fifth beam has not timed out, and the count value of the counter associated with the fifth beam is greater than or equal to a second threshold. That is, after each counter count, it is necessary to check whether the count value of a new beam's associated counter reaches the second threshold. If the count value of a new beam's associated counter reaches the second threshold and the timer associated with that new beam has not timed out, the triggering condition is considered met.

[0303] Optionally, each of the N first beams is associated with multiple counters, each counter corresponding to multiple different difference intervals and multiple different weights. Each counter starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls within its corresponding difference interval, and a second value is incremented with each count. The triggering condition may include: the timer associated with the fifth beam has not expired, and the value obtained by multiplying the count value of the first counter among the multiple counters associated with the fifth beam with its corresponding weight is greater than or equal to a third threshold. That is, after each count by a counter associated with a new beam, the count value of that counter needs to be multiplied with its corresponding weight. If the value obtained after multiplication is greater than or equal to the third threshold and the timer associated with the new beam has not expired, the triggering condition is considered met.

[0304] S460, network device starts beam management.

[0305] Optionally, initiating beam management may include switching the second beam to the fifth beam.

[0306] Optionally, after beam management is complete, the terminal device can set the timer and counter associated with each of the N first beams to 0. Based on this, the current triggering process ends.

[0307] Based on this implementation, when the terminal device detects that the measured value of the reference signal quality of a new beam (e.g., a beam among the N first beams) satisfies the first relationship, even if the timers associated with each of the N first beams have not been started, the terminal device can start a timer and counter mechanism to determine whether to trigger beam reporting in order to request the network device to start beam management.

[0308] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0. (For example, if the timer associated with a new beam times out, or the timer associated with a new beam is reconfigured, or the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be faulty, and the counter associated with the faulty new beam can be set to 0.) This avoids the problem of false triggering caused by the faulty new beam triggering beam reporting, thereby ensuring the stability of signal transmission.

[0309] Figure 5 This is a schematic flowchart of another method for triggering beam reporting provided in this application (i.e., implementation method 4). For example... Figure 5 As shown, the method 500 may include steps 510 to 550, and each step in the method is described in detail below. It should be understood that in this implementation, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0310] S510: When the network device receives N first messages sequentially from the terminal device, it sequentially starts the timer and counter associated with each of the N first beams. Here, N is an integer greater than or equal to 1.

[0311] Among them, the N first messages are used to instruct the terminal device to sequentially detect that the measured value of the reference signal quality of each of the N first beams satisfies the first relationship when the timer associated with each of the N first beams is not started.

[0312] It should be understood that the introduction of the N first beams and second beams involved in this implementation method can be found above, and will not be repeated here.

[0313] It should be noted that the above statement, "When receiving N first messages from the terminal device in sequence, the N first messages are used to instruct the terminal device to sequentially detect that the measured value of the reference signal quality of each of the N first beams satisfies the first relationship when the timer associated with each of the N first beams is not started, and to sequentially start the timer and counter associated with each of the N first beams," can be understood as follows: "When the timer associated with each of the N first beams is not started, if the terminal device detects that the measured value of the reference signal quality of beam 1 satisfies the first relationship, it first sends a message to the network device to report the event, so that the network device can start the timer and counter associated with beam 1; subsequently, if the terminal device detects that the measured value of the reference signal quality of beam 2 satisfies the first relationship, it sends another message to the network device to report the event, so that the network device can start the timer and counter associated with beam 2 again, and so on."

[0314] It should be understood that in this implementation, each of the N first beams is associated with a timer; each of the N first beams can be associated with one timer or multiple timers.

[0315] Optionally, the first relationship mentioned above can be any of the following:

[0316] Example 1: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the sum of the measured value of the reference signal quality of the second beam and a first threshold.

[0317] The specific values ​​of the thresholds involved in this implementation (e.g., any one or more of the first threshold to the eleventh threshold) can be configured or indicated by RRC, MAC CE or DCI, or can be configured in a predefined way. This application does not limit this.

[0318] Example 2: The measured reference signal quality of at least one of the N first beams is greater than or equal to a fourth threshold, and the measured reference signal quality of the second beam is less than or equal to a fifth threshold. Wherein, the fourth threshold is greater than the fifth threshold.

[0319] Example 3: The measured values ​​of the reference signal quality of L of the N first beams are greater than or equal to the sum of the measured values ​​of the reference signal quality of the second beam and the sixth threshold.

[0320] Example 4: The measured value of the reference signal quality of one of the N first beams is greater than or equal to the seventh threshold.

[0321] Example 5, the difference between the measured value of the reference signal quality of at least one of the N first beams and the measured value of the reference signal quality of the second beam is less than or equal to the eighth threshold.

[0322] Example 6: The measured reference signal quality of at least K of the N first beams is greater than or equal to the measured reference signal quality of the second beam.

[0323] Example 7: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the minimum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the ninth threshold.

[0324] Example 8: The measured value of the reference signal quality of at least one of the N first beams is greater than or equal to the sum of the maximum value of the measured value of the reference signal quality corresponding to the active transmission configuration indication state and the tenth threshold.

[0325] It should be understood that the first relation listed above is only an example, and the actual first relation can also be other relations, which this application does not limit.

[0326] Optionally, the metric for the reference signal quality can be any one or more of L1-RSRP, L1-SINR, RSRQ, RSSI, and RSCP. It should be understood that the reference signal qualities listed above are merely examples, and the actual reference signal quality can be other than those listed herein; this application does not limit the specific reference signal quality.

[0327] S520, the terminal device sequentially sends M second messages to the network device. Correspondingly, the network device sequentially receives the M second messages sent by the terminal device.

[0328] Each of the M second messages is used to indicate that the terminal device detects, within a time window specified by a timer associated with a certain beam among the N first beams, that the measured value of the reference signal quality of that certain beam satisfies the first relationship according to a preset period.

[0329] S530, the network device updates the counter associated with the corresponding beam sequentially based on M second messages.

[0330] It should be understood that the measured value of the reference signal quality of the beam will change over time. Therefore, within the time window specified by the timer, the measured value of the reference signal quality of each beam needs to be continuously detected according to a preset rule, and the counter is updated based on the latest measured value of the detected reference signal quality.

[0331] In one possible implementation, each of the N first beams is associated with a counter, and the first value is incremented each time a count is performed.

[0332] It should be understood that the first value can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0333] Optionally, the first value can be a fixed value (e.g., a value such as 1, 2, or 3) or a dynamic value (e.g., the first value can be determined based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam).

[0334] For example, the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the larger the corresponding first value can be; the smaller the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the smaller the corresponding first value can be.

[0335] Optionally, the network device may include a correspondence between multiple different difference intervals and multiple different first values. The determination of the first value based on the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam includes: determining the difference interval in which the difference between the measured value of the reference signal quality of each of the N first beams and the measured value of the reference signal quality of the second beam lies; and determining the corresponding first value based on the difference interval.

[0336] Optionally, the larger the difference included in the difference interval, the larger the first value corresponding to the difference interval can be. For example, multiple different difference intervals may include a first difference interval [a,b), a second difference interval [b,c), a third difference interval [c,d), and so on, where a < b < c < d; the first difference interval [a,b) corresponds to the value 1, the second difference interval [b,c) corresponds to the value 1.5, the third difference interval [c,d) corresponds to the value 2, and so on. This makes it possible that in certain scenarios (for example, when the first relationship is Example 1; other scenarios can be found above and will not be repeated), the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding count value, thus reaching the trigger condition faster and improving the efficiency of beam reporting.

[0337] It should be understood that the difference range can be configured or indicated by RRC, MAC CE or DCI, or it can be configured in a predefined way. This application does not limit this.

[0338] In another possible implementation, each of the N first beams is associated with multiple counters, which correspond to multiple different difference intervals and multiple different weights. Each of the multiple counters starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls into the corresponding difference interval, and increments by a second value each time a count is performed.

[0339] Optionally, the larger the difference included in the difference interval, the larger the weight corresponding to the difference interval can be. For example, each beam can be associated with three counters (counter 1, counter 2, and counter 3). Counter 1 corresponds to the first difference interval [a, b) and a weight of 10%, counter 2 corresponds to the second difference interval [b, c) and a weight of 20%, and counter 3 corresponds to the third difference interval [c, d) and a weight of 30%, where a < b < c < d. This makes it possible that in certain scenarios (e.g., when the first relationship is as in Example 1; other scenarios can be found above and will not be repeated here), the larger the difference between the measured value of the reference signal quality of the new beam and the measured value of the reference signal quality of the current beam, the higher the corresponding weight, thus enabling the triggering condition to be reached more quickly and improving the efficiency of beam reporting.

[0340] Optionally, the larger the difference included in the difference interval, the smaller the weight corresponding to the difference interval can be. This needs to be determined in combination with the specific circumstances of the first relationship, and this application does not impose any restrictions on this.

[0341] The second value can be 1, 2, 3, etc., and this application does not limit it.

[0342] It should be understood that the difference range, weight, and second value can be configured or indicated by RRC, MAC CE, or DCI, or can be configured in a predefined manner. This application does not limit this.

[0343] S540, when the network device detects that the fourth beam among the N first beams meets the target conditions, it sets the counter associated with the fourth beam to 0.

[0344] The target conditions include: the timer associated with the fourth beam times out, the timer associated with the fourth beam is reconfigured, the counter associated with the fourth beam is reconfigured, the reference signal corresponding to the fourth beam is reconfigured, or the reference signal corresponding to the fourth beam is no longer configured.

[0345] It should be understood that timer timeout means that the timer has exceeded the time window specified by the timer. When the timer associated with a new beam times out, the timer associated with the new beam and the counter associated with the new beam can be set to 0, so that the new beam becomes invalid.

[0346] It should be understood that reconfiguring a timer can be interpreted as setting the timer to 0. It should also be understood that when a timer associated with a new beam is set to 0, the timer returns to an inactive state. Therefore, the counter associated with the new beam can be set to 0, thus disabling the new beam.

[0347] It should be understood that reconfiguring the counter can be interpreted as setting the counter to 0; reconfiguring the reference signal can be interpreted as the reference signal being instructed to be deactivated by the higher layer; and no longer configuring the reference signal can be interpreted as the reference signal being instructed to be updated by the higher layer.

[0348] For example, MAC-CE or DCI indicating the TCI state can cause the reference signal to be reconfigured or deconfigured.

[0349] It should be understood that if all new beams fail when all new beams meet the target conditions, the current triggering process can be terminated. It should also be understood that after the current triggering process ends, the timer and counter can only be restarted when the measured value of the reference signal quality of a new beam again satisfies the first relationship.

[0350] S550: When a network device detects that the timer and counter associated with the fifth beam out of N first beams meet the trigger conditions, it initiates beam management.

[0351] It should be noted that the fifth beam among the N first beams can be understood as the beam that first meets the triggering condition. This means that, based on the scheme of this application, the beam that is first triggered to report can be the one associated with the timer and counter among the N first beams.

[0352] Optionally, if each of the N first beams is associated with a counter, and a first value is incremented with each count, the triggering condition may include: the timer associated with the fifth beam has not timed out, and the count value of the counter associated with the fifth beam is greater than or equal to a second threshold. That is, after each counter count, it is necessary to check whether the count value of a new beam's associated counter reaches the second threshold. If the count value of a new beam's associated counter reaches the second threshold and the timer associated with that new beam has not timed out, the triggering condition is considered met.

[0353] Optionally, each of the N first beams is associated with multiple counters, each counter corresponding to multiple different difference intervals and multiple different weights. Each counter starts counting when the difference between the measured value of the reference signal quality of the corresponding beam and the measured value of the reference signal quality of the second beam falls within its corresponding difference interval, and a second value is incremented with each count. The triggering condition may include: the timer associated with the fifth beam has not expired, and the value obtained by multiplying the count value of the first counter among the multiple counters associated with the fifth beam with its corresponding weight is greater than or equal to a third threshold. That is, after each count by a counter associated with a new beam, the count value of that counter needs to be multiplied with its corresponding weight. If the value obtained after multiplication is greater than or equal to the third threshold and the timer associated with the new beam has not expired, the triggering condition is considered met.

[0354] Optionally, initiating beam management may include switching the second beam to the fifth beam.

[0355] Optionally, after beam management is complete, the network device can reset the timer and counter associated with each of the N first beams to 0. Based on this, the current triggering process ends.

[0356] Based on this implementation, when the terminal device detects that the measured value of the reference signal quality of a new beam (e.g., a beam among the N first beams) satisfies the first relationship, even if the timers associated with each of the N first beams have not been started, the terminal device can report the event to the network device, so that the network device can start a timer and counter mechanism to determine whether beam management is triggered.

[0357] Furthermore, during the counter counting process, if a new beam (e.g., the fourth beam among N first beams) is detected to meet the target condition, the counter associated with that beam can be set to 0. (For example, if the timer associated with a new beam times out, or the timer associated with a new beam is reconfigured, or the counter associated with a new beam is reconfigured, or the reference signal corresponding to a new beam is reconfigured, or the reference signal corresponding to a new beam is no longer configured, the new beam can be considered to be faulty, and the counter associated with the faulty new beam can be set to 0.) This avoids the problem of false triggering caused by the faulty new beam triggering beam reporting, thereby ensuring the stability of signal transmission.

The following, in conjunction with... Figure 6 and Figure 7The trigger beam reporting device and the trigger beam management device provided in the embodiments of this application are described respectively.
