[0035] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0036] Beam failure event detection procedure

[0037] Currently, if the physical layer of the terminal device detects that the block error rate (BLER) of all beams corresponding to the physical downlink control channel (PDCCH) is lower than a specified threshold, it is recorded as a beam failure instance (BFI), at which time the physical layer of the terminal device can report a BFI to the media access control (MAC) layer. Generally, the physical layer needs to periodically report the BFI to the MAC layer, and if it is not reported at a certain time, it is considered that there is no BFI.

[0038] Correspondingly, the MAC layer maintains a related beam failure detection timer and a beam failure counter (BFI_COUNTER). In order to ensure the reliability of beam failure detection, whenever the MAC layer receives a BFI report, it starts or restarts the beam failure detection timer, and at the same time, the beam failure counter takes a value of 1. If the beam failure detection timer expires, the terminal device will reset the beam failure counter (i.e., take a value of 0). If the value of the beam failure counter reaches a specified maximum value during the running of the beam failure detection timer, the MAC layer of the terminal device will judge that a beam failure event (for example, the first beam failure event and / or the second beam failure event introduced below) has occurred.

[0039] Beam failure recovery operation

[0040] On the one hand, if the MAC layer of the terminal device detects that a beam failure event has occurred, and before the beam failure event, the terminal device has obtained the beam failure recovery configuration configured by the network device, the terminal device performs the beam failure recovery operation according to the following rules.

[0041] Suppose the terminal device obtains the reference signal receiving power (RSRP) measurement result of the beam, if there is at least one RSRP measurement result of the beam corresponding to the reference signal that is greater than the first threshold indicated by the beam failure recovery configuration in the RSRP measurement result of the beam corresponding to all reference signals configured by the beam failure recovery configuration configured by the network device, the terminal device can select the non-contention random access resource associated with the beam whose RSRP measurement result is greater than the first threshold to initiate a random access process. After initiating the non-contention random access process, if the response of the network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0042] Conversely, if the RSRP measurement results of all beams corresponding to the reference signals configured by the beam failure recovery configuration configured by the network device are all less than or equal to the first threshold indicated by the beam failure recovery configuration, the terminal device selects one beam based on the implementation of the terminal device and initiates a random access procedure based on a contention random access resource. After initiating the contention random access procedure, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful.

[0043] On the other hand, if the MAC layer of the terminal device detects that a beam failure event occurs, and the terminal device does not obtain the beam failure recovery configuration configured by the network device before the beam failure event occurs, the beam failure recovery operation is performed according to the following rules.

[0044] The terminal device selects one beam based on the implementation of the terminal device and initiates a random access procedure based on a contention random access resource. After initiating the contention random access procedure, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful.

[0045] It should be understood that in the embodiments of the present application, the measurement result of a beam is equivalent to the beam level measurement result corresponding to the beam. That is, the measurement result of a beam and the beam level measurement result corresponding to the beam are not distinguished in the embodiments of the present application. In addition, the measurement quantity corresponding to the measurement result can be RSRP.

[0046] As described above, the traditional beam failure recovery mechanism is introduced under the non-AI function, and the additional impact of AI technology is not considered at the beginning of introduction. At present, some discussions are mainly focused on the AI-based beam management function, and how to operate the AI-based beam failure recovery mechanism in the beam failure scenario is not defined. How to use AI technology to realize a more green and energy-saving beam failure recovery mechanism is a direction worth considering.

[0047] Therefore, in order to solve the above problems, the first operation associated with the beam failure recovery is introduced in the embodiments of the present application, which is beneficial to realize a more green and energy-saving beam failure recovery mechanism. The method of wireless communication in the embodiments of the present application is introduced below in combination with FIG. 2. The method shown in FIG. 2 includes step S210.

[0048] In step S210, if a first event occurs, the terminal device performs a first operation associated with beam failure recovery based on a first reference signal set.

[0049] In some implementations, the first reference signal set is determined by a beam failure recovery configuration, wherein the beam failure recovery configuration can be configured by a first network device for the terminal device (such as by dedicated signaling configuration), for example, see step S220 in FIG. 2.

[0050] In the embodiments of the present application, the reference signal type indicated in the first reference signal set is not limited. For example, the reference signal indicated in the first reference signal set can include a synchronization signal / physical broadcast channel block (SS / PBCH block or SSB) or a channel state information reference signal (CSI-RS). Of course, in the embodiments of the present application, the reference signal indicated in the first reference signal set can also be other reference signals introduced in future communication systems.

[0051] In some implementations, the first event includes that the terminal device detects a first beam failure event, or the terminal device triggers a connection re-establishment procedure. In some scenarios, the first event can be a preset event or an event agreed in the protocol, and therefore, the first event is also referred to as a "preset event".

[0052] In some implementations, the first event includes that the terminal device detects a first beam failure event, before the occurrence of the first event, the terminal device can be performing a beam management function based on an AI function, or performing a beam management function based on a non-AI function, which is not limited in the embodiments of the present application.

[0053] As described above, the first event can include two implementations, and the first operation is different for different implementations. Therefore, the following will be introduced in combination with scenario one and scenario two.

[0054] Scenario one: the first event includes that the terminal device detects a first beam failure event, or in other words, the first event includes a first beam failure event.

[0055] In scheme 1, the first reference signal set is indicated by the first parameter included in the beam failure recovery configuration, and all the reference signals indicated in the first reference signal set are agreed by default to be reference signals that need to be actually measured by the terminal device.

[0056] In some implementations, the above-mentioned default agreement can include a protocol agreement, for example.

[0057] In some implementations, the first parameter is used to indicate one or more of the following: identification information of a beam associated with the reference signal indicated in the first reference signal set; a non-contention random access resource associated with the beam associated with the reference signal indicated in the first reference signal set.

[0058] For example, the first parameter is used to indicate the identification information of the beam associated with the indicated reference signal in the first reference signal set. For another example, the first parameter is used to indicate the contention-free random access resource associated with the beam associated with the indicated reference signal in the first reference signal set. For another example, the first parameter is used to indicate the identification information of the beam associated with the indicated reference signal in the first reference signal set and the contention-free random access resource corresponding to the associated beam.

[0059] In some implementations, the identification information of the beam associated with the indicated reference signal in the first reference signal set can include the identification information of one or more beams. For example, the identification information of the beam can include the SSB beam identification or the CSI-RS beam identification.

[0060] In some implementations, the beam associated with the indicated reference signal in the first reference signal set can include one or more beams, and accordingly, the first parameter is further used to indicate the contention-free random access resource associated with the one or more beams.

[0061] In some implementations, if the measurement result of the first beam among the beams associated with the indicated reference signal in the first reference signal set is greater than the first threshold, the first operation includes initiating the random access procedure based on the first contention-free random access resource associated with the first beam, wherein the first contention-free random access resource is indicated by the first parameter; and / or if the measurement result of any one of the beams associated with the indicated reference signal in the first reference signal set is less than or equal to the first threshold, the first operation includes initiating the random access procedure based on the contention random access resource.

[0062] In some implementations, the first threshold can be indicated by the beam failure recovery configuration. For details, refer to the first threshold in the beam failure recovery operation described above.

[0063] In some implementations, the measurement result of one or more beams among the beams associated with the indicated reference signal in the first reference signal set can be greater than the first threshold. At this time, the beam with the measurement result greater than the first threshold can include the first beam. That is, the measurement result of the first beam among the beams associated with the indicated reference signal in the first reference signal set being greater than the first threshold can be understood as that there is one or more beams among the beams associated with the indicated reference signal in the first reference signal set with the measurement result greater than the first threshold.

[0064] In some implementations, the measurement result of any one of the beams associated with the indicated reference signal in the first reference signal set is less than or equal to the first threshold, or in other words, the measurement result of the beam associated with all the indicated reference signals in the first reference signal set is less than or equal to the first threshold.

[0065] In the embodiments of the present application, the measurement quantity corresponding to the measurement result of the first beam is not limited. In some implementations, the measurement quantity corresponding to the measurement result can be RSRP, also referred to as "RSRP measurement result". For example, the RSRP measurement result can be L1-RSRP measurement result. In other implementations, the measurement quantity corresponding to the measurement result can be signal to interference plus noise ratio (SINR), also referred to as "SINR measurement result". For example, the SINR measurement result can be L1-SINR measurement result. In other implementations, the measurement quantity corresponding to the measurement result can be reference signal receiving quality (RSRQ), also referred to as "RSRQ measurement result". For example, the RSRQ measurement result can be L1-RSRQ measurement result.

[0066] In scheme 1, whether it is a non-AI-based beam management function or an AI-based beam management function, the behavior of the terminal device after beam failure remains consistent, which is conducive to simplifying the behavior of the terminal device after beam failure, that is, a new beam failure recovery operation mechanism does not need to be introduced separately for the AI-based beam management function.

[0067] For example, the first network device sends the beam failure recovery configuration to the terminal device for configuring: the first threshold, SSB beam identifier 1 and the non-contention random access resource associated with SSB beam identifier 1, SSB beam 2 and the non-contention random access resource associated with SSB beam identifier 2, SSB beam 3 and the non-contention random access resource associated with SSB beam identifier 3, wherein the reference signal associated with SSB beam identifier 1, the reference signal associated with SSB beam identifier 2, and the reference signal associated with SSB beam identifier 3 are the reference signals that the terminal device needs to actually measure. Therefore, after the beam failure event occurs, the terminal device can obtain the RSRP measurement result associated with SSB beam identifier 1, the RSRP measurement result associated with SSB beam identifier 2, and the RSRP measurement result associated with SSB beam identifier 3 based on the actual measurement process.

[0068] Correspondingly, if the RSRP measurement results of part or all of the three beams are greater than the first threshold, the terminal device selects the non-contention random access resource associated with the beam with the RSRP measurement result greater than the first threshold to initiate the random access process. After initiating the non-contention random access process, if the response of the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0069] On the contrary, if the RSRP measurement result of all of the three beams is less than or equal to the first threshold value, the terminal device selects one beam and initiates a random access procedure based on a contention random access resource. After initiating the contention random access procedure, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful.

[0070] It should be noted that the manner in which the terminal device selects the beam to initiate the contention-based random access procedure is not limited. The manner in which the beam is selected can depend on the specific implementation of the terminal device.

[0071] In scheme 2, the first reference signal set is indicated by a first parameter included in the beam failure recovery configuration.

[0072] In scheme 2, configuration manner 1, the first parameter is used to indicate the first part of reference signals, at this time, the set composed of the first part of reference signals is the first reference signal set, wherein the first part of reference signals are reference signals that need to be actually measured by the terminal device. That is to say, under the configuration manner 1, all the reference signals indicated in the first reference signal set are reference signals that need to be actually measured by the terminal device.

[0073] In some implementations, the first parameter is used to indicate one or more of the following: identification information of the beam associated with the first part of reference signals, non-contention random access resources associated with the beam associated with the first part of reference signals.

[0074] For example, the first parameter is used to indicate the identification information of the beam associated with the first part of reference signals. For another example, the first parameter is used to indicate the non-contention random access resources associated with the beam associated with the first part of reference signals. For another example, the first parameter is used to indicate the identification information of the beam associated with the first part of reference signals and the non-contention random access resources associated with the corresponding beam.

[0075] In some implementations, the identification information of the beam associated with the first part of reference signals can include the identification information of one or more beams. Wherein the identification information of the beam can include, for example, SSB beam identification or CSI-RS beam identification.

[0076] In some implementations, the beam associated with the first part of reference signals can include one or more beams, and accordingly, the first parameter is also used to indicate the non-contention random access resources associated with the one or more beams.

[0077] In some implementations, if the measurement result of the first beam among the beams associated with the reference signals indicated in the first part of the reference signals is greater than the first threshold, the first operation comprises initiating the random access procedure based on the first non-contention random access resource associated with the first beam; and / or if the measurement result of any one of the beams associated with the reference signals indicated in the first part of the reference signals is less than or equal to the first threshold, the first operation comprises initiating the random access procedure based on the contention random access resource.

[0078] In some implementations, the measurement result of one or more beams among the beams associated with the reference signals indicated in the first part of the reference signals is greater than the first threshold, and the beam with the measurement result greater than the first threshold can comprise the first beam. That is, the measurement result of the first beam among the beams associated with the reference signals indicated in the first part of the reference signals being greater than the first threshold can be understood as that there is one or more beams among the beams associated with the reference signals indicated in the first part of the reference signals with the measurement result greater than the first threshold.

[0079] In some implementations, the measurement result of any one of the beams associated with the reference signals indicated in the first part of the reference signals is less than or equal to the first threshold, or the measurement result of the beams associated with all the reference signals indicated in the first part of the reference signals is less than or equal to the first threshold.

[0080] In the embodiments of the present application, the measurement result of the first beam is not limited. In some implementations, the measurement quantity corresponding to the measurement result can be RSRP, also referred to as "RSRP measurement result". For example, the RSRP measurement result can be L1-RSRP measurement result. In other implementations, the measurement quantity corresponding to the measurement result can be SINR, also referred to as "SINR measurement result". For example, the SINR measurement result can be L1-SINR measurement result. In other implementations, the measurement quantity corresponding to the measurement result can be RSRQ, also referred to as "RSRQ measurement result". For example, the RSRQ measurement result can be L1-RSRQ measurement result.

[0081] In the configuration mode 1 of the scheme 2, whether based on the non-AI beam management function or the AI beam management function, the behavior of the terminal device after beam failure remains consistent, which is conducive to simplifying the behavior of the terminal device after beam failure, that is, a new beam failure recovery operation mechanism does not need to be introduced separately for the AI-based beam management function.

[0082] In the configuration mode 2 of the scheme 2, the first parameter is used to indicate the first part of reference signals and the second part of reference signals, and at this time, the set composed of the first part of reference signals and the second part of reference signals is the first reference signal set, wherein the terminal device needs to actually measure the first part of reference signals, and the terminal device does not need to actually measure the second part of reference signals.

[0083] In some implementations, the measurement result of the second part of reference signals can be determined based on the AI-based beam prediction function.

[0084] In some scenarios, the beams associated with the first part of reference signals can belong to Set B, and the beams associated with the second part of reference signals can belong to Set A, and the measurement results of all or part of the beams in Set A can be predicted based on the measurement results (i.e., actual measurement results) of the beams in Set B.

[0085] In the configuration mode 2 of the scheme 2, not all of the first reference signal set configured by the first network device are reference signals that can be actually measured by the terminal device, in other words, in one configuration process, the first part of reference signals among all the reference signals involved in the beam failure recovery configuration configured by the first network device to the terminal device are reference signals that can be actually measured by the terminal device, and the second part of reference signals are reference signals that do not need to be actually measured by the terminal device. As described above, the second part of reference signals can be reference signals whose measurement results are predicted based on the AI function, therefore, in practice, the first network device does not transmit the second part of reference signals, or the first network device transmits the second part of reference signals according to a period longer than that of the first part of reference signals, which can save the power consumption of the first network device in transmitting part of the reference signals. For the terminal device, it also does not need to actually measure this part of the reference signals, which can also save the energy consumption to a certain extent.

[0086] In the embodiments of the present application, the scenario in which the first network device does not transmit the second part of reference signals is not limited. For example, in the case where the AI-based beam prediction function monitoring is not started, the first network device does not transmit the second part of reference signals.

[0087] In the embodiments of the present application, the scenario in which the first network device transmits the second part of reference signals according to a period longer than that of the first part of reference signals is not limited. For example, in the scenario for the purpose of AI-based beam prediction function monitoring, the transmission period of the first part of reference signals is 80 ms, and the transmission period of the second part of reference signals is 480 ms. Generally, except for the scenario of periodically actually measuring the second part of reference signals caused by the performance monitoring task, the measurement results of the second part of reference signals are obtained through the AI function prediction process.

[0088] On the other hand, compared with the non-AI-based beam failure recovery function, the first network device can configure less reference signal that needs to be actually measured by the terminal device for the AI-based beam failure recovery function, but since the AI-based beam failure recovery function introduces the AI-based beam prediction function, the AI-based beam failure recovery function can achieve good beam failure recovery function under the condition of measuring less reference signal, which reflects the advantage of AI technology.

[0089] As described above, the first parameter is used to indicate the first part of the reference signal and the second part of the reference signal, and in some implementations, the first parameter is used to indicate one or more of the following: identification information of a beam associated with the first part of the reference signal; non-contention random access resource associated with the beam associated with the first part of the reference signal; identification information of a beam associated with the second part of the reference signal; non-contention random access resource associated with the beam associated with the second part of the reference signal, wherein the introduction of the identification information of the beam can be referred to the foregoing.

[0090] In the embodiments of the present application, the first parameter is used to indicate one of the above information. For example, the first parameter is used to indicate the identification information of the beam associated with the first part of the reference signal. For another example, the first parameter is used to indicate the non-contention random access resource associated with the beam associated with the first part of the reference signal. For another example, the first parameter is used to indicate the identification information of the beam associated with the second part of the reference signal. For another example, the first parameter is used to indicate the non-contention random access resource associated with the beam associated with the second part of the reference signal.

[0091] In the embodiments of the present application, the first parameter is used to indicate any of the above information. For example, the first parameter is used to indicate: the identification information of the beam associated with the first part of reference signals; the non-contention random access resource associated with the beam associated with the first part of reference signals; the identification information of the beam associated with the second part of reference signals; the non-contention random access resource associated with the beam associated with the second part of reference signals. For another example, the first parameter is used to indicate: the identification information of the beam associated with the first part of reference signals; the non-contention random access resource associated with the beam associated with the first part of reference signals. For another example, the first parameter is used to indicate: the identification information of the beam associated with the second part of reference signals; the non-contention random access resource associated with the beam associated with the second part of reference signals. For another example, the first parameter is used to indicate: the identification information of the beam associated with the first part of reference signals; the non-contention random access resource associated with the beam associated with the first part of reference signals; the identification information of the beam associated with the second part of reference signals. For another example, the first parameter is used to indicate: the identification information of the beam associated with the first part of reference signals; the non-contention random access resource associated with the beam associated with the first part of reference signals; the non-contention random access resource associated with the beam associated with the second part of reference signals. The combination of the above information indicated by the first parameter is not limited in the embodiments of the present application.

[0092] As described above, if the first parameter is used to indicate the first part of reference signals and the second part of reference signals, in some implementation manners, the first operation includes determining the measurement result of the beam associated with part or all of the reference signals that do not need to be actually measured by the terminal device based on one or more of the following information: the measurement result of the beam associated with all of the reference signals that need to be actually measured by the terminal device; the measurement result of the beam associated with part of the reference signals that need to be actually measured by the terminal device; the identification information of the beam associated with all of the reference signals that need to be actually measured by the terminal device; the identification information of the beam associated with part of the reference signals that need to be actually measured by the terminal device; the identification information of the beam associated with the reference signals that do not need to be actually measured by the terminal device; wherein the reference signals that need to be actually measured by the terminal device include the first part of reference signals, and the reference signals that do not need to be actually measured by the terminal device include the second part of reference signals.

[0093] In the embodiments of the present application, the above reference signals that need to be actually measured by the terminal device are not limited. In some implementation manners, the reference signals that need to be actually measured by the terminal device include the first part of reference signals, which can be understood as that the reference signals that need to be actually measured by the terminal device are the first part of reference signals.

[0094] For example, the reference signal actually measured by the terminal device in need of which is configured by the first network device is the reference signal actually measured by the terminal device in need of which in the AI-based beam failure recovery function (i.e., the first part of the reference signal). Assuming that the reference signal actually measured by the terminal device in need of which is configured by the first network device includes the reference signal corresponding to SSB beam identifier 1, the reference signal corresponding to SSB beam identifier 3, and the reference signal corresponding to SSB beam identifier 5, at this time, the reference signal included in the first part of the reference signal is the reference signal corresponding to SSB beam identifier 1, the reference signal corresponding to SSB beam identifier 3, and the reference signal corresponding to SSB beam identifier 5. Therefore, the first part of the reference signal is all the reference signals actually measured by the terminal device in need of which.

[0095] In some other implementations, the reference signal actually measured by the terminal device in need of which includes the first part of the reference signal, which can be understood as the first part of the reference signal being part of the reference signal actually measured by the terminal device in need of which configured by the first network device.

[0096] For example, the reference signal actually measured by the terminal device in need of which is configured by the first network device includes the reference signal actually measured by the terminal device in need of which in the non-AI-based beam failure recovery function (i.e., the traditional beam failure recovery function), and the reference signal actually measured by the terminal device in need of which in the AI-based beam failure recovery function (i.e., the first part of the reference signal) can be part of the reference signal actually measured by the terminal device in need of which in the non-AI-based beam failure recovery function.

[0097] For another example, the reference signal actually measured by the terminal device in need of which is configured by the first network device includes the reference signal actually measured by the terminal device in need of which indicated in the layer 3 (or layer 1) measurement configuration, and the reference signal actually measured by the terminal device in need of which in the AI-based beam failure recovery function (i.e., the first part of the reference signal) can be part of the reference signal actually measured by the terminal device in need of which indicated in the layer 3 (or layer 1) measurement configuration.

[0098] Assuming that the first network device configures the terminal device in the layer 3 (or layer 1) measurement configuration or the non-AI-based beam failure recovery function (i.e., the traditional beam failure recovery function) that needs the terminal device to actually measure the reference signals including: the reference signal corresponding to the SSB beam identifier 1, the reference signal corresponding to the SSB beam identifier 3, the reference signal corresponding to the SSB beam identifier 5, and the reference signal corresponding to the SSB beam identifier 7. Among them, the reference signals (i.e., the first part of the reference signals) configured for the AI-based beam failure recovery function that need the terminal device to actually measure the reference signals include: the reference signal corresponding to the SSB beam identifier 1, the reference signal corresponding to the SSB beam identifier 3, and the reference signal corresponding to the SSB beam identifier 5. Therefore, the first part of the reference signals is part of the reference signals that need the terminal device to actually measure.

[0099] For the convenience of understanding, the first operation in the embodiment of the application is introduced below in combination with Examples 1-6. Assuming that the first part of the reference signals in the first reference signal set contains the reference signal indicated by the SSB beam identifier 1 and the reference signal indicated by the SSB beam identifier 3. The beams corresponding to the reference signals that need the terminal device to actually measure, which are configured by the first network device through the layer 3 (or layer 1) measurement configuration or the beam failure recovery configuration, include: the beam indicated by the SSB beam identifier 1, the beam indicated by the SSB beam identifier 3, the beam indicated by the SSB beam identifier 5, and the beam indicated by the SSB beam identifier 7.

[0100] In addition, the second part of the reference signals in the first reference signal set contains the reference signal indicated by the SSB beam identifier 2 and the reference signal indicated by the SSB beam identifier 4. The beams corresponding to the reference signals that do not need the terminal device to actually measure, which are configured by the first network device through the layer 3 (or layer 1) measurement configuration or the beam failure recovery configuration, include: the beam indicated by the SSB beam identifier 2, the beam indicated by the SSB beam identifier 4, the beam indicated by the SSB beam identifier 6, and the beam indicated by the SSB beam identifier 8.

[0101] It should be noted that for the sake of brevity of subsequent description, the "beam indicated by the SSB beam identifier n" will be referred to as SSB beam n hereinafter, wherein n is a positive integer.

[0102] Example 1: The first operation includes: determining the measurement results of the beams associated with all the reference signals that do not need the terminal device to actually measure based on the measurement results of the beams associated with all the reference signals that need the terminal device to actually measure.

[0103] For example, the terminal device obtains, through an actual measurement process, an RSRP measurement result corresponding to SSB beam 1, an RSRP measurement result corresponding to SSB beam 3, an RSRP measurement result corresponding to SSB beam 5, and an RSRP measurement result corresponding to SSB beam 7, and infers, according to the RSRP measurement results corresponding to the above four beams, an RSRP measurement result corresponding to SSB beam 2 and an RSRP measurement result corresponding to SSB beam 4.

[0104] For example, the terminal device obtains, through an actual measurement process, an RSRP measurement result corresponding to SSB beam 1, an RSRP measurement result corresponding to SSB beam 3, an RSRP measurement result corresponding to SSB beam 5, and an RSRP measurement result corresponding to SSB beam 7, and infers, according to the RSRP measurement results corresponding to the above four beams, an RSRP measurement result corresponding to SSB beam 2 and an RSRP measurement result corresponding to SSB beam 4.

[0105] Example 2: The first operation includes determining, based on measurement results of beams associated with all of the reference signals that need to be actually measured by the terminal device, measurement results of beams associated with part of the reference signals that do not need to be actually measured by the terminal device.

[0106] For example, the terminal device obtains, through an actual measurement process, an RSRP measurement result corresponding to SSB beam 1, an RSRP measurement result corresponding to SSB beam 3, an RSRP measurement result corresponding to SSB beam 5, and an RSRP measurement result corresponding to SSB beam 7, and infers, according to the RSRP measurement results corresponding to the above four beams, an RSRP measurement result corresponding to SSB beam 2 and an RSRP measurement result corresponding to SSB beam 4.

[0107] For example, the terminal device obtains, through an actual measurement process, an RSRP measurement result corresponding to SSB beam 1, an RSRP measurement result corresponding to SSB beam 3, an RSRP measurement result corresponding to SSB beam 5, and an RSRP measurement result corresponding to SSB beam 7, and infers, according to the RSRP measurement results corresponding to the above four beams, an RSRP measurement result corresponding to SSB beam 2 and an RSRP measurement result corresponding to SSB beam 4.

[0108] Example 3: The first operation includes determining, based on measurement results of beams associated with part of the reference signals that need to be actually measured by the terminal device, measurement results of beams associated with part of the reference signals that do not need to be actually measured by the terminal device.

[0109] For example, the terminal device obtains, through an actual measurement process, the RSRP measurement result corresponding to the SSB beam 1 and the RSRP measurement result corresponding to the SSB beam 3, and obtains, according to the RSRP measurement results corresponding to the above 2 beams, the RSRP measurement result corresponding to the SSB beam 2 and the RSRP measurement result corresponding to the SSB beam 4.

[0110] For example, the terminal device obtains, through an actual measurement process, the RSRP measurement result corresponding to the SSB beam 1 and the RSRP measurement result corresponding to the SSB beam 3, and obtains, according to the RSRP measurement results corresponding to the above 2 beams, the RSRP measurement result corresponding to the SSB beam 2 and the RSRP measurement result corresponding to the SSB beam 4.

[0111] Example 4: The first operation comprises determining, based on the measurement results of the beams associated with all the reference signals actually measured by the terminal device, the identification information of the beams associated with all the reference signals actually measured by the terminal device, and the identification information of the beams associated with the reference signals not actually measured by the terminal device, the measurement results of the beams associated with all the reference signals not actually measured by the terminal device.

[0112] For example, the terminal device obtains, through an actual measurement process, the RSRP measurement result corresponding to the SSB beam 1 and the RSRP measurement result corresponding to the SSB beam 3, and obtains, according to the RSRP measurement results corresponding to the above 2 beams, the RSRP measurement result corresponding to the SSB beam 2 and the RSRP measurement result corresponding to the SSB beam 4.

[0113] For example, the terminal device obtains, through an actual measurement process, the RSRP measurement result corresponding to the SSB beam 1 and the RSRP measurement result corresponding to the SSB beam 3, and obtains, according to the RSRP measurement results corresponding to the above 2 beams, the RSRP measurement result corresponding to the SSB beam 2 and the RSRP measurement result corresponding to the SSB beam 4.

[0114] Example 5: The first operation comprises determining the measurement results of the beams associated with the second part of reference signals based on the measurement results of the beams associated with all of the reference signals actually measured by the terminal device, the identification information of the beams associated with all of the reference signals actually measured by the terminal device, and the identification information of the beams associated with the second part of reference signals, wherein the reference signals actually measured by the terminal device comprise the first part of reference signals.

[0115] For example, the terminal device can obtain the RSRP measurement results of SSB beam 1, SSB beam 3, SSB beam 5 and SSB beam 7 through the actual measurement process, and infer the RSRP measurement results of SSB beam 2 and SSB beam 4 according to the RSRP measurement results of the above 4 beams, the identification information of the above 4 beams and the beam identification of the second part of reference signals (i.e. SSB beam identification 2 and SSB beam identification 4).

[0116] For example, the terminal device can obtain the RSRP measurement results of SSB beam 1, SSB beam 3, SSB beam 5 and SSB beam 7 through the actual measurement process, and infer the RSRP measurement results of SSB beam 2 and SSB beam 4 according to the RSRP measurement results of the above 4 beams, the identification information of the above 4 beams and the beam identification of the second part of reference signals (i.e. SSB beam identification 2 and SSB beam identification 4).

[0117] Example 6: The first operation comprises determining the measurement results of the beams associated with the second part of reference signals based on the measurement results of the beams associated with part of the reference signals actually measured by the terminal device, the identification information of the beams associated with part of the reference signals actually measured by the terminal device, and the identification information of the beams associated with the second part of reference signals, wherein the reference signals actually measured by the terminal device comprise the first part of reference signals.

[0118] For example, the terminal device can obtain the RSRP measurement results of SSB beam 1, SSB beam 3, SSB beam 5 and SSB beam 7 through the actual measurement process, and infer the RSRP measurement results of SSB beam 2 and SSB beam 4 according to the RSRP measurement results of the above 4 beams, the identification information of the above 4 beams and the beam identification of the second part of reference signals (i.e. SSB beam identification 2 and SSB beam identification 4).

[0119] For example, the terminal device obtains, through an actual measurement process, an RSRP measurement result corresponding to SSB beam 1 and an RSRP measurement result corresponding to SSB beam 3, and infers, according to the RSRP measurement results of the two beams, the identification information of the two beams, and the beam identifications of the second part of reference signals (i.e., SSB beam identification 2 and SSB beam identification 4), the RSRP measurement result corresponding to SSB beam 2 and the RSRP measurement result corresponding to SSB beam 4.

[0120] It should be noted that the first operation in the embodiments of the present application is introduced above by taking Examples 1 to 6 as examples. In the embodiments of the present application, the implementation manner of the first operation is not limited, and the first operation can also have other implementation manners.

[0121] For example, the part of reference signals that need to be actually measured by the terminal device can be the first part of reference signals, and correspondingly, the first operation in Example 6 can be understood as: determining the measurement result of the beam associated with the second part of reference signals based on the measurement result of the beam associated with the first part of reference signals, the identification information of the beam associated with the first part of reference signals, and the identification information of the beam associated with the second part of reference signals. The first operation in Example 3 can be understood as: determining the measurement result of the beam associated with the second part of reference signals based on the measurement result of the beam associated with the first part of reference signals.

[0122] For example, the first operation can also include: determining the measurement result of the beam associated with the second part of reference signals based on the measurement result of the beam associated with the first part of reference signals and the identification information of the beam associated with the second part of reference signals.

[0123] For example, the first operation can also include: determining the measurement result of the beam associated with the reference signal that does not need to be actually measured by the terminal device based on the measurement result of the beam associated with the first part of reference signals and the identification information of the beam associated with the reference signal that does not need to be actually measured by the terminal device.

[0124] For example, the first operation can also include: determining the measurement result of the beam associated with the reference signal that does not need to be actually measured by the terminal device based on the measurement result of the beam associated with the first part of reference signals, the identification information of the beam associated with the first part of reference signals, and the identification information of the beam associated with the reference signal that does not need to be actually measured by the terminal device.

[0125] In some implementations, if the terminal device obtains the measurement results of the beams corresponding to all reference signals configured by the beam failure recovery configuration, i.e., the measurement results of the beams corresponding to the first part of reference signals and the measurement results of the beams corresponding to the second part of reference signals, the above method further includes: the terminal device performs one or more of the following operations.

[0126] For example, the terminal device performs: if there is at least one measurement result of a beam corresponding to a reference signal greater than the first threshold value in the measurement results of the beams corresponding to the first part of reference signals and the measurement results of the beams corresponding to the second part of reference signals, the terminal device selects a non-contention random access resource associated with the beam with the measurement result greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response from the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0127] For another example, the terminal device performs: if the measurement results of the beams corresponding to all reference signals (for example, the first part of reference signals and the second part of reference signals) configured by the beam failure recovery configuration are all less than or equal to the first threshold value, the terminal device selects one beam and initiates a random access process based on a contention random access resource. After initiating the contention random access process, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful.

[0128] For another example, if there is at least one measurement result of a beam corresponding to a reference signal greater than the first threshold value in the measurement results of the beams corresponding to the first part of reference signals and the measurement results of the beams corresponding to the second part of reference signals, the terminal device selects a non-contention random access resource associated with the beam with the measurement result greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response from the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0129] And if the measurement results of the beams corresponding to all reference signals (for example, the first part of reference signals and the second part of reference signals) configured by the beam failure recovery configuration are all less than or equal to the first threshold value, the terminal device selects one beam and initiates a random access process based on a contention random access resource. After initiating the contention random access process, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful.

[0130] In one aspect, the embodiments of the present application allow the reference signals involved in the beam failure recovery configuration configured by the first network device not necessarily to be all reference signals that can be actually measured by the terminal device, which can save resources for the first network device to send actually measured reference signals. In other words, compared with the non-AI-based beam failure recovery mechanism, the first network device can configure fewer reference signals that need to be actually measured by the terminal device for the AI-based beam failure recovery mechanism. However, due to the introduction of the AI-based beam prediction function in the beam failure recovery mechanism, the AI-based beam failure recovery mechanism can achieve good beam failure recovery function under the condition of measuring fewer reference signals, which embodies the advantage of AI technology.

[0131] On the other hand, in the embodiments of the present application, if the beam failure recovery configuration involves the second part of reference signals (i.e. the reference signals that do not need to be actually measured by the terminal device), the terminal device can obtain the measurement results corresponding to the second part of reference signals by inference, wherein the process of determining the measurement results corresponding to the second part of reference signals is relatively simple.

[0132] As described above, the second part of reference signals can be indicated based on the first parameter, at this time, the non-contention random access resources associated with the beams associated with the second part of reference signals can all be used for beam failure recovery. In other implementations, whether the non-contention random access resources associated with the beams associated with the second part of reference signals can be used for beam failure recovery can be determined based on the first condition. The first condition of the embodiments of the present application is introduced first below.

[0133] In some implementations, the first condition includes one of the following: the measurement results of all the beams indicated by the target beam set are greater than a second threshold; the measurement results of the top K beams with the best measurement results among all the beams indicated by the target beam set are greater than the second threshold; and the AI function related to the measurement result prediction is still in an activated state.

[0134] In some implementations, the first condition includes that the AI function related to the measurement result prediction is still in an activated state (or the AI function related to the measurement result prediction is in an activated state), wherein the AI function related to the measurement result can be understood as an AI-based beam management function and / or an AI-based beam failure recovery function.

[0135] In some implementations, taking the RSRP measurement result as an example, the measurement results of all the beams indicated by the target beam set being greater than the second threshold can include the RSRP measurement results of all the beams indicated by the target beam set being greater than the second threshold. Wherein the second threshold can be configured by the beam failure recovery configuration or configured by the protocol definition process.

[0136] In the embodiments of the present application, the second threshold is not limited. In some implementations, the second threshold can be the same threshold as the first threshold, to simplify the beam failure recovery configuration. In other implementations, the second threshold can be a different threshold (i.e. independent configuration) from the first threshold, which helps to improve the flexibility of the second threshold setting.

[0137] In some embodiments, the measurement results of the first K beams with the best measurement results among all the beams indicated by the target beam set are all greater than the second threshold, where K is a positive integer greater than or equal to 1. That is, the measurement results of the beams in beam set 1 in the target beam set are all greater than the second threshold, and the measurement results of the beams in beam set 1 are all greater than or equal to the measurement results of the beams other than the beams in beam set 1 in the target beam set.

[0138] Taking the RSRP measurement result as an example, the RSRP measurement results of the first K beams with the best measurement results among all the beams indicated by the target beam set are all greater than the second threshold.

[0139] In the embodiments of the present application, the second threshold is not limited. In some embodiments, the second threshold can be the same threshold as the first threshold, or in other words, the first threshold and the second threshold are configured by the same parameter in the beam failure recovery configuration to simplify the beam failure recovery configuration. In other embodiments, the second threshold can be a different threshold from the first threshold, or in other words, the first threshold and the second threshold are configured by different parameters in the beam failure recovery configuration, which helps to improve the flexibility of the second threshold setting.

[0140] In the embodiments of the present application, the target beam set is not limited. In some embodiments, the target beam set includes one of the following: beams associated with all reference signals in the reference signals that need to be actually measured by the terminal device; beams associated with all reference signals in the first part of reference signals; beams associated with part of the reference signals in the reference signals that need to be actually measured by the terminal device; the first beam set. Wherein, the reference signals that need to be actually measured by the terminal device, the first part of reference signals and the second part of reference signals can be referred to the introduction above.

[0141] In some embodiments, the target beam set includes beams associated with part of the reference signals in the reference signals that need to be actually measured by the terminal device, and the measurement results of the beams associated with the part of the reference signals can be used to infer the measurement results of the beams associated with the second part of the reference signals.

[0142] In some embodiments, the first beam set is configured for the terminal device by the first network device through the beam failure recovery configuration or through the layer 3 or layer 1 measurement configuration. In the embodiments of the present application, if the first beam set is configured for the terminal device by the first network device through the beam failure recovery configuration, the parameters carrying the first beam set are different from the parameters carrying the first part of the reference signals and the parameters carrying the second part of the reference signals, or in other words, the parameters indicating the first beam set, the parameters indicating the first part of the reference signals and the parameters indicating the second part of the reference signals are all different parameters.

[0143] In some scenarios, the target beam set can be pre-agreed. For example, it can be predetermined by a protocol. Therefore, the target beam set is also referred to as an "agreed beam set".

[0144] For ease of understanding, the target beam set of the embodiments of the present application is introduced below in combination with Examples 7-10. It is assumed that the first part of the reference signals in the first reference signal set includes the reference signal indicated by SSB beam identifier 1 and the reference signal indicated by SSB beam identifier 3. The beams corresponding to the reference signals that need to be actually measured by the terminal device are configured by the first network device through the layer 3 (or layer 1) measurement configuration or the beam failure recovery configuration, and include the beam indicated by SSB beam identifier 1, the beam indicated by SSB beam identifier 3, the beam indicated by SSB beam identifier 5, and the beam indicated by SSB beam identifier 7.

[0145] In addition, the second part of the reference signals in the first reference signal set includes the reference signal indicated by SSB beam identifier 2 and the reference signal indicated by SSB beam identifier 4. The beams corresponding to the reference signals that do not need to be actually measured by the terminal device are configured by the first network device through the layer 3 (or layer 1) measurement configuration or the beam failure recovery configuration, and include the beam indicated by SSB beam identifier 2, the beam indicated by SSB beam identifier 4, the beam indicated by SSB beam identifier 6, and the beam indicated by SSB beam identifier 8.

[0146] It should be noted that for subsequent description, the "beam indicated by SSB beam identifier n" is referred to as SSB beam n hereinafter, where n is a positive integer.

[0147] Example 7: If the target beam set includes the beams associated with all the reference signals that need to be actually measured by the terminal device, the target beam set includes SSB beam 1, SSB beam 3, SSB beam 5, and SSB beam 7.

[0148] Example 8: If the target beam set includes all the beams corresponding to the first part of the reference signals, the target beam set includes SSB beam 1 and SSB beam 3.

[0149] Example 9: If the target beam set includes the beams associated with part of the reference signals that need to be actually measured by the terminal device, the target beam set includes SSB beam 1, SSB beam 3, and SSB beam 5. This is because the beams corresponding to the second part of the reference signals include SSB beam 2 and SSB beam 4, and if the measurement results of the beams corresponding to the second part of the reference signals are to be obtained by reasoning, the measurement results of SSB beam 1, SSB beam 3, and SSB beam 5 need to be input as AI model.

[0150] Example 10: If the target beam set includes the first beam set, for example, the first beam set contains SSB beam 1 and SSB beam 7.

[0151] In one aspect, the scheme of the embodiments of the present application allows the reference signals involved in the beam failure recovery configuration configured by the network device not necessarily all to be reference signals that can be actually measured by the terminal device, which can save the resources of the network device for transmitting the actually measured reference signals, in other words, compared with the non-AI-based beam failure recovery mechanism, the network device can configure less reference signals that need to be actually measured by the terminal device for the AI-based beam failure recovery mechanism, but since the AI-based beam failure recovery mechanism introduces the AI-based beam prediction function, the AI-based beam failure recovery mechanism can achieve good beam failure recovery function under the condition of measuring less reference signals, which embodies the advantage of AI technology.

[0152] On the other hand, whether the measurement result corresponding to the second part of reference signals can be obtained through the AI function inference process depends not only on whether the second part of reference signals is involved in the beam failure recovery configuration, but also on whether the first condition is met, which has the benefit of avoiding the execution of the AI inference process under the condition of poor accuracy, which helps to improve the performance of the AI-based beam failure recovery function. Otherwise, when the first condition is not met, the AI inference process is still executed, and the measurement result corresponding to the second part of reference signals with low accuracy will affect the overall performance of the beam failure recovery function, therefore, determining whether to execute the AI inference process by judging the first condition is conducive to guaranteeing the overall performance of the AI-based beam failure recovery function.

[0153] The first condition in the embodiments of the present application is introduced above, and the first operation when the first condition is met or not met is introduced below in combination with the scheme of the embodiments of the present application.

[0154] Based on the introduction above, it can be known that in the case where the first condition is met, the non-contention random access resources associated with the beams associated with the second part of reference signals can all be used for beam failure recovery (accurately speaking, in the case where the first condition is met, the non-contention random access resources associated with the beams associated with the second part of reference signals can be used as candidate resources for the beam failure recovery process, and whether they can actually be used depends on whether the measurement result of the beam associated with the second part of reference signals is greater than the first threshold), at this time, the first operation performed by the terminal device is similar to the first operation performed by the terminal device when the first condition is not introduced, which can be referred to the introduction above, for example, the first operation introduced in combination with examples 1-6.

[0155] In some implementations, if the measurement result of the second beam is greater than the first threshold, the first operation includes initiating a random access procedure based on a second non-contention random access resource associated with the second beam, where the second beam is one of the beams associated with the first part of reference signals or the second beam is one of the beams associated with the second part of reference signals, if the first condition is met.

[0156] If the measurement result of the third beam is less than or equal to the first threshold, the first operation includes initiating a random access procedure based on a contention random access resource, where the third beam is any one of the beams associated with the first part of reference signals or the third beam is any one of the beams associated with the second part of reference signals.

[0157] That is, if the terminal device obtains the measurement results of the beams corresponding to all the reference signals configured by the beam failure recovery configuration (i.e., the measurement results of the beams corresponding to the first part of reference signals and the measurement results of the beams corresponding to the second part of reference signals), the terminal device can continue to perform one or more of the following operations.

[0158] For example, the terminal device performs: taking the measurement result as the RSRP measurement result as an example, if there is at least one RSRP measurement result of the beam corresponding to the reference signal among the RSRP measurement results of the beams corresponding to the first part of reference signals and the RSRP measurement results of the beams corresponding to the second part of reference signals is greater than the first threshold included in the beam failure recovery configuration, the terminal device selects a non-contention random access resource associated with the beam whose RSRP measurement result is greater than the first threshold to initiate a random access procedure. After initiating the non-contention random access procedure, if a response from the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0159] Conversely, if the RSRP measurement results of the beams corresponding to all the reference signals configured by the beam failure recovery configuration configured by the first network device are all less than or equal to the first threshold included in the beam failure recovery configuration, the terminal device can select a beam and initiate a random access procedure based on a contention random access resource. After initiating the contention random access procedure, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful. Wherein, the application embodiments do not limit the way the terminal device selects the beam, which can depend on the implementation of the terminal device.

[0160] For example, the terminal device performs: taking the measurement result as an RSRP measurement result, if there is at least one RSRP measurement result of a beam corresponding to a reference signal greater than a first threshold value contained in the beam failure recovery configuration in the RSRP measurement result of the beam corresponding to the first part of the reference signal and the RSRP measurement result of the beam corresponding to the second part of the reference signal, the terminal device selects a non-contention random access resource associated with the beam whose RSRP measurement result is greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response from the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0161] For example, the terminal device performs: if all RSRP measurement results of beams corresponding to reference signals configured by the beam failure recovery configuration configured by the first network device are less than or equal to the first threshold value contained in the beam failure recovery configuration, the terminal device can select a beam and initiate a random access process based on a contention random access resource. After initiating the contention random access process, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful. The embodiments of the present application do not limit the way the terminal device selects the beam, which can depend on the implementation of the terminal device.

[0162] In other implementations, if the first condition is not met, the first operation (for example, the first operation introduced in combination with examples 1-6) is not performed. In other words, the first operation is not performed or stopped in the case where the first condition is not met (for example, the terminal device can also activate the AI prediction function before the beam failure event occurs, so as to quickly infer the measurement result of the beam corresponding to the second part of the reference signal when the beam failure event occurs and the first condition is met). Where the first condition is not met indicates that the non-contention random access resource associated with the beam associated with the second part of the reference signal cannot be used for beam failure recovery. That is, at this time, only the non-contention random access resource associated with the beam associated with the first part of the reference signal will be used for the beam failure recovery process.

[0163] In some implementations, in the case where the first condition is not met, if the measurement result of the fourth beam in the beam associated with the first part of the reference signal is greater than the first threshold value, the first operation includes initiating a random access process based on the third non-contention random access resource associated with the fourth beam; and / or, if the measurement result of the beam associated with the first part of the reference signal is less than or equal to the first threshold value, the first operation includes initiating a random access process based on a contention random access resource associated with a certain beam in the beam associated with the first part of the reference signal.

[0164] For example, the terminal device performs: if there is at least one RSRP measurement result of a beam corresponding to a reference signal greater than the first threshold value in the RSRP measurement results of the beams corresponding to the first part of the reference signals, the terminal device selects a non-contention random access resource associated with the beam with the RSRP measurement result greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response of the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0165] In the above manner, after the terminal device obtains the RSRP measurement results of the beams corresponding to the first part of the reference signals, the terminal device can continue to perform one or more of the following operations.

[0166] For example, the terminal device performs: if there is at least one RSRP measurement result of a beam corresponding to a reference signal greater than the first threshold value in the RSRP measurement results of the beams corresponding to the first part of the reference signals, the terminal device selects a non-contention random access resource associated with the beam with the RSRP measurement result greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response of the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0167] And if the RSRP measurement results of the beams corresponding to the first part of the reference signals are all less than or equal to the first threshold value, the terminal device selects one beam and initiates a random access process based on a contention random access resource. After initiating the contention random access process, if the contention resolution is successfully completed, the terminal device considers that the beam failure recovery is successful. The manner in which the terminal device selects the beam can depend on the implementation of the terminal device.

[0168] For example, the terminal device performs: if there is at least one RSRP measurement result of a beam corresponding to a reference signal greater than the first threshold value in the RSRP measurement results of the beams corresponding to the first part of the reference signals, the terminal device selects a non-contention random access resource associated with the beam with the RSRP measurement result greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response of the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0169] For example, the terminal device performs: if there is at least one RSRP measurement result of a beam corresponding to a reference signal greater than the first threshold value in the RSRP measurement results of the beams corresponding to the first part of the reference signals, the terminal device selects a non-contention random access resource associated with the beam with the RSRP measurement result greater than the first threshold value to initiate a random access process. After initiating the non-contention random access process, if a response of the first network device is successfully received, the terminal device considers that the beam failure recovery is successful.

[0170] In some implementations, the method further includes: if the first event occurs, the terminal device performs a second operation, the second operation including: the terminal device stopping the AI-based beam management function; and / or after the beam failure recovery succeeds, the terminal device falling back to a non-AI-based beam management function.

[0171] In some implementations, if the terminal device detects that the beam failure event occurs, it may indicate that the beam selected by the AI-based beam management function has poor performance, at which time the terminal device can stop the AI-based beam management function.

[0172] In some implementations, if the terminal device detects that the beam failure event occurs, it may indicate that the beam selected by the AI-based beam management function has poor performance, at which time the terminal device can fall back to a non-AI-based beam management function for beam measurement and feedback.

[0173] In some implementations, if the terminal device detects that the beam failure event occurs, it may indicate that the beam selected by the AI-based beam management function has poor performance, at which time the terminal device can stop the AI-based beam management function and perform a beam failure recovery operation. After the beam failure recovery operation succeeds, the terminal device can fall back to a non-AI-based beam management function for beam measurement and feedback.

[0174] In some implementations, a second beam failure event occurs before the first beam failure event, and the method further includes: if the first beam failure event occurs and the time interval between the occurrence time of the first beam failure event and the occurrence time of the second beam failure event is less than a first time threshold, the terminal device performs a third operation, wherein the third operation includes one or more of the following: the terminal device stops the AI-based beam management function; after the beam failure recovery succeeds, the terminal device sends first information to the first network device; after the beam failure recovery succeeds, the terminal device falls back to a non-AI-based beam management function. The first time threshold is configured to the terminal device in one or more of the following ways: a dedicated signaling manner; a system broadcast message manner; a protocol predefinition manner.

[0175] In some implementations, the second beam failure event is the last beam failure event of the first beam failure event. Of course, in the embodiments of the present application, the second beam failure event and the first beam failure event can be separated by one or more beam failure events.

[0176] Taking the third operation including the terminal device stopping the AI-based beam management function as an example, if the first beam failure event occurs after the second beam failure event, it may indicate that the beam selected by the AI-based beam management function has poor performance, at which time the terminal device stops the AI-based beam management function.

[0177] For example, the third operation includes that the terminal device sends the first information to the first network device, and the terminal device sends the first information to the serving cell.

[0178] In the embodiments of the present application, if the first beam failure event occurs after the second beam failure event, it may indicate that the performance of the beam selected based on the AI-based beam management function is poor. At this time, the terminal device can indicate to the first network device through the first information that the terminal device detects the first beam failure event.

[0179] For example, the third operation includes that the terminal device falls back to the non-AI-based beam management function after the successful execution of the beam failure recovery. If the first beam failure event occurs after the second beam failure event, it may indicate that the performance of the beam selected based on the AI-based beam management function is poor. At this time, the terminal device falls back to the non-AI-based beam management function after the successful execution of the beam failure recovery.

[0180] In the embodiments of the present application, the third operations introduced above can be used independently, or the third operations introduced above can be used in combination.

[0181] For example, when the first beam failure event occurs, the terminal device can stop the AI-based beam management function, and after the successful execution of the beam failure recovery operation, the terminal device sends the first information to the serving cell to indicate that the terminal device detects the first beam failure event.

[0182] For another example, when the first beam failure event occurs, the terminal device can stop the AI-based beam management function. After the successful execution of the beam failure recovery operation, the terminal device falls back to the non-AI-based beam management function to perform beam measurement and feedback.

[0183] For another example, when the first beam failure event occurs, the terminal device can trigger the beam failure recovery operation. After the successful execution of the beam failure recovery operation, the terminal device sends the first information to the serving cell to indicate that the terminal device detects the first beam failure event. At the same time, after the successful execution of the beam failure recovery operation, the terminal device can fall back to the non-AI-based beam management function to perform beam measurement and feedback.

[0184] For another example, when the terminal device detects the first beam failure event and judges that the beam failure occurs, the terminal device stops the AI-based beam management function. After the successful execution of the beam failure recovery operation, the terminal device sends the first information to the serving cell to indicate that the terminal device detects the first beam failure event. At the same time, after the successful execution of the beam failure recovery operation, the terminal device falls back to the non-AI-based beam management function to perform beam measurement and feedback.

[0185] In some implementations, one or more of operations 1-3 can be performed if the first beam failure event occurs and the beam failure recovery execution fails. For example, operation 1 can be performed. For another example, operation 2 can be performed. For yet another example, operation 3 can be performed. For yet another example, operation 1 and operation 2 can be performed. For yet another example, operation 1 and operation 3 can be performed. For yet another example, operation 2 and operation 3 can be performed. For yet another example, operation 1, operation 2, and operation 3 can be performed.

[0186] Operation 1: Triggering a connection re-establishment procedure, the terminal device can send a first MAC CE (also referred to as "first MAC CE information") to the second network device, the first MAC CE is used to indicate that the terminal device beam failure recovery execution fails.

[0187] That is to say, if the terminal device detects that the beam failure event occurs and the beam failure recovery operation fails, the terminal device performs the following behavior: triggering a connection re-establishment procedure, sending a first MAC CE to the cell selected by the connection re-establishment procedure, the first MAC CE is used to indicate that the terminal device has occurred beam failure recovery operation failure.

[0188] In some implementations, the first MAC CE information can include fourth information and / or first cell identification information. Wherein the fourth information is used to indicate that the terminal device has occurred beam failure recovery operation failure. The first cell identification information is used to indicate the cell where the beam failure recovery operation failure event occurs. For example: the first cell identification information is indicated by CGI or (PCI + frequency point information) or serving cell index.

[0189] In some implementations, the first MAC CE information is sent together with the connection reestablishment request message. In this way, the terminal device can inform the specific reason for triggering the connection reestablishment by the cell selected in the connection reestablishment process as early as possible. The connection reestablishment trigger cause (ReestablishmentCause) contained in the conventional connection reestablishment request message is very limited (see the three reasons of reconfigurationFailure, handoverFailure and otherFailure shown in the following code), limited by the number of bits carried by the connection reestablishment request message. Extending the connection reestablishment request message to further indicate the specific reason information for triggering the connection reestablishment by the terminal device will greatly change the conventional communication process. Therefore, the embodiment of the present application proposes to define a first MAC CE at the MAC layer to carry the specific reason information for triggering the connection reestablishment by the terminal device which cannot be carried by the connection reestablishment request message, so that the cell selected in the connection reestablishment process of the terminal device receives the first MAC CE at the same time as receiving the connection reestablishment request message, to assist the second network device in determining whether to reply with a connection reestablishment message or a connection establishment message. ReestablishmentCause::=ENUMERATED{reconfigurationFailure,handoverFailure,otherFailure,spare1}

[0190] Of course, in the embodiment of the present application, the first MAC CE is sent separately from the connection reestablishment request message to improve the flexibility of transmitting the first MAC CE.

[0191] In some implementations, the second network device is a network device selected through the connection reestablishment process. The second network device can be a different network device from the first network device, of course, in the embodiment of the present application, the first network device can be the same network device as the second network device.

[0192] Operation 2: Triggering the connection reestablishment process, the terminal device sends a connection reestablishment completion message to the second network device, and the connection reestablishment completion message includes second information indicating that the terminal device beam failure recovery execution fails. The second network device is a network device selected through the connection reestablishment process.

[0193] That is, the terminal device detects that a beam failure event occurs and the beam failure recovery operation fails, and the terminal device performs the following behavior: triggering the connection reestablishment process, sending a connection reestablishment completion message to the cell selected in the connection reestablishment process (i.e. the second network device) and the connection reestablishment completion message includes second information to indicate that the terminal device has a beam failure recovery operation failure.

[0194] In this way, the terminal device sends a connection re-establishment request message to the cell selected by the connection re-establishment process, and then the network device replies to the terminal device with a connection re-establishment message. Subsequently, the terminal device can send a connection re-establishment complete message to the cell selected by the connection re-establishment process, wherein the connection re-establishment complete message includes second information to indicate that the terminal device has failed in the beam failure recovery operation.

[0195] In some implementations, the second information further includes second cell identification information, wherein the second cell identification information is used to indicate the cell in which the beam failure recovery operation failure event occurs. For example, the second cell identification information can be indicated by a CGI or (PCI + frequency point information) or a serving cell index.

[0196] In the embodiments of the present application, by carrying the second information in the connection re-establishment complete message, the second network device can know the specific reason for the terminal device triggering the connection re-establishment, i.e., the terminal device has failed in the beam failure recovery operation. In this way, the second network device can consider deactivating the AI-based beam management function (i.e., falling back to using the non-AI-based beam management function), so as to avoid the AI-based beam management function from causing longer performance degradation of the system.

[0197] In some implementations, the second network device is a network device selected by the connection re-establishment process. The second network device can be a different network device from the first network device, and of course, in the embodiments of the present application, the first network device can be the same network device as the second network device.

[0198] Operation 3: Triggering a connection re-establishment process, the terminal device sends a connection establishment complete message to the second network device, and the connection establishment complete message includes third information used to indicate that the terminal device has failed in the beam failure recovery operation. The second network device is a network device selected by the connection re-establishment process.

[0199] That is, when the terminal device detects that a beam failure event occurs and the beam failure recovery operation fails, the terminal device performs the following behavior: triggering a connection re-establishment process, sending a connection re-establishment request message to the cell (i.e., the second network device) selected by the connection re-establishment process, and accordingly, the cell selected by the connection re-establishment process replies to the terminal device with a connection establishment message (corresponding to the re-establishment fallback scenario). The terminal device sends a connection establishment complete message to the cell selected by the connection re-establishment process, wherein the connection establishment complete message includes third information to indicate that the terminal device has failed in the beam failure recovery operation.

[0200] In some implementations, the third information further includes third cell identification information, the third cell identification information being used to indicate a cell in which the beam failure recovery operation failure event occurs. For example, the third cell identification information is indicated by a CGI or (PCI + frequency point information) or a serving cell index.

[0201] In the embodiments of the present application, by carrying the third information in the connection reestablishment completion message, the second network device can know the specific reason for the terminal device triggering the connection reestablishment, i.e., the terminal device has a beam failure recovery operation failure. In this way, the second network device can consider deactivating the AI-based beam management function (i.e., falling back to using the non-AI-based beam management function), avoiding the AI-based beam management function from causing longer performance degradation of the system.

[0202] In some implementations, the second network device is a network device selected through the connection reestablishment process. The second network device can be a different network device from the first network device, and of course, in the embodiments of the present application, the first network device can be the same network device as the second network device.

[0203] From the perspective of the second network device performing operations 1-3, the above method includes the second network device performing one or more of the following: receiving the first MAC CE information sent by the terminal device in the connection reestablishment process, the first MAC CE information being used to indicate that the terminal device beam failure recovery execution fails; receiving the connection reestablishment completion message sent by the terminal device in the connection reestablishment process, and the connection reestablishment completion message including the second information, the second information being used to indicate that the terminal device beam failure recovery execution fails; receiving the connection establishment completion message sent by the terminal device in the connection reestablishment process, and the connection establishment completion message including the third information, the third information being used to indicate that the terminal device beam failure recovery execution fails.

[0204] In some implementations, if the first beam failure event occurs and the beam failure recovery execution fails, the second network device performs one or more of the above operations 1-3. For example, the second network device performs operation 1. For another example, the second network device performs operation 2. For another example, the second network device performs operation 3. For another example, the second network device performs operation 1 and operation 2. For another example, the second network device performs operation 1 and operation 3. For another example, the second network device performs operation 2 and operation 3. For another example, the second network device performs operation 1, operation 2, and operation 3.

[0205] It should be noted that the above operation 2 and operation 3 are not mutually exclusive schemes, but two different branches of a scheme, operation 2 is for the terminal device to send a connection re-establishment request message to the network device, and the second network device replies to the connection re-establishment message. Branch. While operation 3 is for the terminal device to send a connection re-establishment request message to the second network device, and the second network device replies to the connection establishment message branch.

[0206] In some implementations, if the first beam failure event occurs and the beam failure recovery execution fails, the terminal device performs one of the following: the terminal device stops the AI-based beam management function; when the connection re-establishment is triggered, the terminal device stops the AI-based beam management function; when the terminal device receives the connection re-establishment message or the connection establishment message sent by the second network device, the terminal device stops the AI-based beam management function.

[0207] In some implementations, the second network device is a network device selected through a connection re-establishment process. The second network device can be a different network device from the first network device, of course, in the embodiments of the present application, the first network device can be the same network device as the second network device.

[0208] Scenario two: the first event includes that the terminal device triggers a connection re-establishment process.

[0209] In some implementations, the terminal device performs one of the following: when the connection re-establishment is triggered, the terminal device stops the AI-based beam management function; when the terminal device receives the connection re-establishment message or the connection establishment message sent by the second network device, the terminal device stops the AI-based beam management function.

[0210] In some implementations, after the terminal device stops the AI-based beam management function, it can fall back to the non-AI-based beam management function for beam measurement and feedback. For example, when the terminal device receives the connection re-establishment message or the connection establishment message sent by the second network device, the terminal device can stop the AI-based beam management function and fall back to the non-AI-based beam management function for beam measurement and feedback.

[0211] In some implementations, the second network device is a network device selected through a connection re-establishment process. The second network device can be a different network device from the first network device, of course, in the embodiments of the present application, the first network device can be the same network device as the second network device.

[0212] In the embodiments of the present application, the reason for triggering the connection re-establishment procedure is not limited. In some implementations, the reason includes one or more of the following: the terminal device experiences radio link failure, reconfiguration failure, synchronization reconfiguration failure, handover failure, integrity protection failure, ciphering failure. It should be understood that in the embodiments of the present application, the above-mentioned reasons can be used alone or in combination with each other, and the present application does not limit the combination mode between the reasons.
