[0136] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0137] Figure 1 This is a schematic flowchart illustrating a beam failure determination method according to an embodiment of the present disclosure. The beam failure determination method shown in the embodiment of the present disclosure can be applied to user equipment, which can be an electronic device such as a mobile phone, tablet computer, wearable device, or vehicle-mounted device. The user equipment can communicate with a base station, for example, based on 4G or 5G.

[0138] The user equipment includes n antenna panels, where n is an integer greater than or equal to 1. Each antenna panel can transmit beams in multiple directions, but can only transmit beams in one direction at any given time.

[0139] like Figure 1 As shown, the beam failure determination method may include the following steps:

[0140] In step S1, based on the received first configuration information, an association relationship is established between n sets of reference signals (RS) and n antenna panels, wherein the i-th set of reference signals is associated with the i-th antenna panel, i≤n; that is, each reference signal in the i-th set of reference signals is associated with the i-th antenna panel.

[0141] In one embodiment, the base station can send first configuration information to the user equipment via RRC (Radio Resource Control) messages.

[0142] It should be noted that even without receiving the first configuration information, the user equipment can still determine the association between the reference signal set and the antenna panel. For example, if the user equipment receives the PDCCH (physical downlink control channel) sent by the base station through the i-th antenna panel, then the reference signal of the beam in which the PDCCH is located can be determined by the user equipment as the reference signal in the associated i-th reference signal set.

[0143] In one embodiment, a set of reference signals may contain one reference signal or multiple reference signals.

[0144] In step S2, all reference signals in at least one of the n reference signal sets are detected to determine whether there is a problem antenna panel with beam failure (BF) in the antenna panel associated with the detected reference signal set.

[0145] In one embodiment, for the i-th antenna panel, it can transmit beams in multiple directions to communicate with the base station. However, in general, the base station will only configure the i-th antenna panel to use a portion of the beams in the multiple directions it can transmit for communication, while the remaining unused beams may include alternative beams (described in subsequent embodiments).

[0146] The reference signals in the i-th reference signal set associated with the i-th antenna panel are used to determine the communication quality of the beam used by the i-th antenna panel to communicate with the base station. If the signal quality of all reference signals in the i-th reference signal set is less than the first quality threshold, it can be determined that the communication quality of the i-th antenna panel with the base station through the beam corresponding to each reference signal in the i-th reference signal set is not good enough, and thus it can be determined that the i-th antenna panel has experienced beam failure.

[0147] For a set of n reference signals, all reference signals in at least one of the reference signal sets can be monitored. For a set of reference signals in which the signal quality of all reference signals is less than a first quality threshold, it can be determined that the antenna panel associated with the reference signal set has experienced beam failure.

[0148] In step S3, if a problematic antenna panel exists, beam failure information is sent to the base station to indicate that the problematic antenna panel has experienced beam failure.

[0149] Among them, the base station can perform beam failure recovery after receiving beam failure information.

[0150] According to embodiments of this disclosure, the user equipment can establish an association between a reference signal set and an antenna panel based on first configuration information. Then, based on the reference signal set, it can determine the antenna panel that has experienced beam failure and send beam failure information to the base station. This can specifically indicate which antenna panel has experienced beam failure, so that the base station can accurately determine the antenna panel in the user equipment that has experienced beam failure and schedule resources accordingly.

[0151] Figure 2 This is a schematic flowchart illustrating another beam failure determination method according to embodiments of the present disclosure. Figure 2 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0152] In step S31, a beam measurement report is sent to the base station. The beam measurement report contains the identification information of the problematic antenna panel, as well as the identification and signal quality information of each reference signal in the set of reference signals associated with the problematic antenna panel.

[0153] The signal quality information includes, but is not limited to, L1 (layer 1, i.e., the physical layer)_RSRP (Reference Signal Receiving Power) and L1_SINR (Signal to Interference plus Noise Ratio).

[0154] In one embodiment, a beam measurement report may be sent to the base station, and the beam measurement report may carry the identification information of the problematic antenna panel, as well as the identification and signal quality information of each reference signal in the set of reference signals associated with the problematic antenna panel. Based on the identification and signal quality information of each reference signal, the base station may determine that the antenna panel has experienced beam failure. Based on the identification information of the problematic antenna panel, the base station may determine which antenna panel in the user equipment has experienced beam failure.

[0155] Furthermore, the beam measurement report can also include the reference signal identifier and corresponding signal quality information in the set of alternative reference signals corresponding to the antenna panel, which makes it easier for the base station to configure the beam corresponding to the new reference signal for the terminal.

[0156] It should be noted that the identification information of the problematic antenna panel proposed in this embodiment and subsequent embodiments can be the ID of the problematic antenna panel, the ID of the reference signal set associated with the problematic antenna panel, or the ID of the reference signal in the reference signal set associated with the problematic antenna panel. The specific information can be set as needed.

[0157] Figure 3 This is a schematic flowchart illustrating another beam failure determination method according to embodiments of the present disclosure. Figure 3 As shown, before sending a beam measurement report to the base station, the step of sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure also includes:

[0158] In step S32, an indication message is sent to the base station. The indication message is included in the scheduling request, or the indication message is a preset random access preamble on a preset random access time-frequency resource. The indication message is used to indicate that there is a problem with the antenna panel in the user equipment.

[0159] If resource configuration information is received from the base station based on the indication information, the beam measurement report is sent to the base station according to the resources configured in the resource configuration information.

[0160] In one embodiment, the user equipment may send a preset random access preamble on a preset random access time-frequency resource as indication information to the base station, or send the indication information to the base station in a scheduling request to inform the base station that it has a problematic antenna panel, but does not specify which antenna panel is the problematic antenna panel.

[0161] After receiving the indication information, the base station can send resource configuration information to the user equipment that needs to determine which antenna panel is the problem antenna panel, so that the user equipment can send the beam measurement report according to the resources configured in the resource configuration information (which may be physical uplink control channel resource PUCCH or physical uplink shared channel resource PUSCH), without having to configure the resources for sending the beam measurement report for all user equipment, which helps to reduce the overhead of base station resource configuration.

[0162] Figure 4 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 4 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0163] In step S33, a scheduling request (SR) is sent to the base station. The scheduling request contains the identification information of the problematic antenna panel.

[0164] In one embodiment, a scheduling request can be sent to the base station, and the scheduling request can carry the identification information of the problematic antenna panel. Based on the identification information of the problematic antenna panel, the base station can determine which antenna panel in the user equipment has experienced beam failure.

[0165] Figure 5 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 5 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0166] In step S34, a MAC CE (Medium Access Control Control Element) signaling message is sent to the base station. The MAC CE signaling message contains information about the problematic antenna panel identifier.

[0167] In one embodiment, a MAC CE signaling message can be sent to the base station, carrying identification information of the problematic antenna panel. Based on the identification information of the problematic antenna panel, the base station can determine which antenna panel in the user equipment has experienced beam failure.

[0168] Specifically, the base station can send the MAC CE signaling to the base station through PUSCH resources, which can be periodically configured by the base station to the user equipment through RRC signaling.

[0169] For an antenna panel in a user equipment, determining whether it is a problem antenna panel can yield different results in different serving cells (on different frequency bands). Therefore, for an antenna panel, there can be multiple determination results based on the number of serving cells configured for the user equipment. Thus, in beam failure information, the number of bits can be determined based on the number of antenna panels of the user equipment and the number of serving cells configured for the user equipment, so as to accurately indicate which antenna panel in which serving cell is the problem antenna panel.

[0170] For example, in MAC CE signaling, different antenna panels belonging to different serving cells can correspond to different bits. For instance, if a user equipment (UE) is determining whether two antenna panels are problematic, and the UE is configured with four serving cells, then there are eight possible determination results for the two antenna panels across the four cells. Therefore, eight bits can be specified in the MAC CE signaling to correspond to these eight determination results. Specific bit positions are used to indicate whether a specific antenna is a problematic antenna panel in a specific cell. For example, a bit of "1" indicates that the specific antenna is a problematic antenna panel in a specific cell, while a bit of "0" indicates that the specific antenna is not a problematic antenna panel in a specific cell.

[0171] Figure 6 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 6 As shown, before sending MAC CE signaling to the base station, the step of sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure also includes:

[0172] In step S35, an indication message is sent to the base station. The indication message is included in the scheduling request, or the indication message is a preset random access preamble on a preset random access time-frequency resource. The indication message is used to indicate that there is a problem with the antenna panel in the user equipment.

[0173] If resource configuration information is received from the base station based on the indication information, the MAC CE signaling is sent to the base station according to the resources configured in the resource configuration information.

[0174] In one embodiment, the user equipment may send a preset random access preamble on a preset random access time-frequency resource as indication information to the base station, or send the indication information to the base station in a scheduling request to inform the base station that it has a problematic antenna panel, but does not specify which antenna panel is the problematic antenna panel.

[0175] After receiving the indication information, the base station can send resource configuration information to the user equipment that needs to determine which antenna panel is the problem antenna panel, so that the user equipment can send the MAC CE signaling according to the resources configured in the resource configuration information (which may be physical uplink shared channel resources), without having to configure resources for sending the MAC CE signaling for all user equipment, which helps to reduce the overhead of base station resource configuration.

[0176] In this embodiment, the PUSCH resources and Figure 5 The PUSCH resources in the illustrated embodiments differ. Figure 5 In the illustrated embodiment, the PUSCH resources are periodically configured to the user equipment by the base station through RRC signaling, while in this embodiment, the PUSCH resources are dynamically configured to the user equipment by the base station through DCI (Downlink Control Information) signaling based on scheduling requests.

[0177] Figure 7 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 7 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0178] In step S36, Channel State Information (CSI) is sent to the base station. In the CSI, the first bit position is equal to a first preset value, and the second bit position is equal to a second preset value. The first preset value is used to represent the identification information of the problematic antenna panel, and the second preset value is used to represent the beam failure.

[0179] In one embodiment, channel state information can be sent to the base station, and the channel state information can carry identification information of the problematic antenna panel. Based on the identification information of the problematic antenna panel, the base station can determine which antenna panel in the user equipment has experienced beam failure.

[0180] In the channel state information, a first bit can be selected to represent the antenna panel identification information, and a second bit can be selected to indicate whether a beam failure has occurred. The first and second positions can contain one or more bits, and if multiple bits are included, the multiple bits can be consecutive or discrete.

[0181] The base station can determine which antenna panel has experienced beam failure based on the bits in the first and second positions. If all antenna panels have experienced beam failure, the bits in the first and second positions can be set to predetermined values, such as all 0 or all 1.

[0182] Figure 8 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 8 As shown, before sending channel state information to the base station, the step of sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure further includes:

[0183] In step S37, an indication message is sent to the base station. The indication message is included in the scheduling request, or the indication message is a preset random access preamble on a preset random access time-frequency resource. The indication message is used to indicate that there is a problem with the antenna panel in the user equipment.

[0184] If resource configuration information is received from the base station based on the indication information, the channel state information is sent to the base station according to the resources configured in the resource configuration information.

[0185] In one embodiment, the user equipment may send a preset random access preamble on a preset random access time-frequency resource as indication information to the base station, or send the indication information to the base station in a scheduling request to inform the base station that it has a problematic antenna panel, but does not specify which antenna panel is the problematic antenna panel.

[0186] After receiving the indication information, the base station can send resource configuration information to the user equipment that needs to determine which antenna panel is the problem antenna panel, so that the user equipment can send the channel state information according to the resources configured in the resource configuration information (which may be physical uplink control channel resources or physical uplink shared channel resources), without having to configure resources to send the channel state information for all user equipment, which helps to reduce the overhead of base station resource configuration.

[0187] Figure 9 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 9 As shown, before sending beam failure information to the base station indicating that the problematic antenna panel has experienced beam failure, the method further includes:

[0188] In step S4, based on the received second configuration information, an association relationship is established between at least one of the antenna panels corresponding to the reference signal set of at least one candidate beam;

[0189] In one embodiment, the base station can send second configuration information to the user equipment via RRC messages.

[0190] The step of sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0191] In step S38, a reference signal in the reference signal set of the candidate beams associated with the problematic antenna panel is detected to determine whether there is a usable reference signal in the reference signal set of the candidate beams.

[0192] In step S39, if a usable reference signal exists, random access is initiated to the base station on the time-frequency resources corresponding to the usable reference signal. The third message of the random access (MSG3) contains the identification information of the problematic antenna panel.

[0193] In one embodiment, the user equipment can establish an association between the reference signal set of the alternative beams and the antenna panel based on the second configuration information. Then, when sending beam failure information to the base station, it can first detect the reference signals in the reference signal set of the alternative beams associated with the problematic antenna panel to determine whether there are any usable reference signals in the reference signal set of the alternative beams.

[0194] For example, for a candidate beam, it can be determined whether there is a usable reference signal with a signal quality greater than the second quality threshold in the reference signal set of the candidate beam. If there is a usable reference signal, it can be determined that the communication quality between the problem antenna panel and the base station through the time-frequency resources corresponding to the usable reference signal (which are transmitted through the beam corresponding to the usable reference signal) can meet the requirements, so that random access can be initiated to the base station on the time-frequency resources corresponding to the usable reference signal.

[0195] However, since the set of alternative reference signals associated with different antenna panels can be the same, that is, the time-frequency resources of the reference signals corresponding to different antenna panels can be the same, different problematic antenna panels can initiate random access to the base station on the time-frequency resources corresponding to the same reference signal. The base station is not sufficient to determine the problematic antenna panel that has experienced beam failure based solely on the time-frequency resources of the reference signal.

[0196] To ensure that the base station can distinguish problematic antenna panels, the identification information of the problematic antenna panel can be carried in the third message of random access. This allows the base station to accurately determine the problematic antenna panel that has experienced beam failure based on the identification information of the antenna panel in the third message of random access.

[0197] Figure 10 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 10As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure further includes:

[0198] In step S3A, if no available reference signal exists, random access is initiated to the base station on the random access time-frequency resources (contention-based random access time-frequency resources) for contention-based random access (the random access preamble sent is a contention-based random access preamble), wherein the third message of random access contains the identification information of the problematic antenna panel.

[0199] In one embodiment, if no available reference signal is available, the user equipment may initiate random access to the base station on the random access resource and carry the identification information of the problematic antenna panel in the third message of the random access.

[0200] Since the random access resources in this embodiment are not time-frequency resources corresponding to the available reference signals, their stability may be relatively weaker than that of the time-frequency resources corresponding to the available reference signals. However, it can still ensure to a certain extent that the user equipment can carry the identification information of the problematic antenna panel to the base station through the third message of random access.

[0201] Figure 11 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 11 As shown, before sending beam failure information to the base station indicating that the problematic antenna panel has experienced beam failure, the method further includes:

[0202] In step S5, based on the received third configuration information, an association relationship is established between the j antenna panels corresponding to the reference signal sets of the j candidate beams. The reference signal set of the j candidate beam is associated with the j antenna panel. Different reference signals in the reference signal set of the j candidate beam correspond to different time-frequency resources and / or different random access preambles, where j≤n.

[0203] In one embodiment, the base station can send third configuration information to the user equipment via RRC messages.

[0204] The step of sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0205] In step S3B, a reference signal in the reference signal set of the candidate beams associated with the problematic antenna panel is detected to determine whether there is a usable reference signal in the reference signal set of the candidate beams.

[0206] In step S3C, if an available reference signal exists, a random access preamble corresponding to the available reference signal is sent to the base station on the time-frequency resources corresponding to the available reference signal.

[0207] In one embodiment, the user equipment can establish an association between the reference signal set of the alternative beams and the antenna panel based on the second configuration information. Then, when sending beam failure information to the base station, it can first detect the reference signals in the reference signal set of the alternative beams associated with the problematic antenna panel to determine whether there are any usable reference signals in the reference signal set of the alternative beams.

[0208] It should be noted that, with Figure 9 Unlike the previous embodiment, this embodiment establishes the association between the j antenna panels corresponding to the reference signal sets of the j candidate beams, and also configures the reference signal set of the j candidate beam to be associated with the j antenna panel. Different reference signals in the reference signal set of the j candidate beam correspond to different time-frequency resources and / or correspond to different random access preambles.

[0209] Accordingly, it can be ensured that different antenna panels are associated with different sets of reference signals, and that different reference signals correspond to different time-frequency resources and / or different random access preambles, thereby enabling different antenna panels to correspond to different time-frequency resources and / or different random access preambles.

[0210] For example, for a candidate beam, it can be determined whether there is a usable reference signal with a signal quality greater than the second quality threshold in the reference signal set of the candidate beam. If a usable reference signal exists, it can be determined that the quality of communication between the problematic antenna panel and the base station through the beam corresponding to the usable reference signal can meet the requirements, so that random access can be initiated to the base station on the time-frequency resources corresponding to the usable reference signal.

[0211] Since different antenna panels correspond to different time-frequency resources and / or different random access preambles, taking the example of different antenna panels corresponding to different time-frequency resources, different problematic antenna panels need to initiate random access to the base station on the time-frequency resources corresponding to different reference signals. The base station can determine the problematic antenna panel that has experienced beam failure based solely on the time-frequency resources of the reference signal.

[0212] Taking different antenna panels corresponding to different random access preambles as an example, different problematic antenna panels need to send different random access preambles when initiating random access to the base station. The base station can determine the problematic antenna panel that has experienced beam failure simply based on the random access preamble.

[0213] based on Figure 11In the embodiment shown, only the first message of random access (MSG1) carrying the random access preamble needs to be sent, and the third message of random access does not need to be sent to the base station, so that the base station can determine which antenna panel has experienced beam failure. Figure 9 and Figure 11 The embodiments shown can be selected according to specific needs.

[0214] Figure 12 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 12 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0215] In step S3D, beam failure information indicating that the problem antenna panel has experienced beam failure is sent to the base station through the problem antenna panel and / or the non-problem antenna panel in the same serving cell as the problem antenna panel among the n antenna panels.

[0216] In one embodiment, the user equipment can send beam failure information to the base station through the problematic antenna panel or through a non-problematic antenna panel that is in the same serving cell as the problematic antenna panel among the n antenna panels. Accordingly, even if there is a problem with the uplink transmission of the problematic antenna panel, the beam failure information can still be successfully sent to the base station through the non-problematic antenna panel, so that the base station can determine which antenna panel in the user equipment has experienced beam failure.

[0217] Figure 13 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 13 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes:

[0218] In step S3E, beam failure information indicating that the problem antenna panel has experienced beam failure is sent to the base station through the problem antenna panel and / or the non-problem antenna panels among the n antenna panels that are in different serving cells from the problem antenna panel. The beam failure information also includes the identification information of the serving cell to which the problem antenna panel belongs.

[0219] In one embodiment, the user equipment can send beam failure information to the base station through the problematic antenna panel or through a non-problematic antenna panel that is in a different serving cell from the problematic antenna panel (i.e., cross-carrier transmission). Accordingly, even if there is a problem with the uplink transmission of the problematic antenna panel, the beam failure information can still be successfully sent to the base station through the non-problematic antenna panel, so that the base station can determine which antenna panel in the user equipment has experienced beam failure.

[0220] It should be noted that when beam failure information is transmitted through a non-problem antenna panel that is in a different serving cell from the problem antenna panel among the n antenna panels, the beam failure information also includes the identification information of the serving cell to which the problem antenna panel belongs, so that the base station can determine the serving cell to which the problem antenna panel belongs.

[0221] Optionally, the serving cell includes at least one of the following:

[0222] Main residential area, main auxiliary residential area, auxiliary residential area.

[0223] Figure 14 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 14 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes multiple methods, including:

[0224] In step S3F, if all n antenna panels are problematic antenna panels, beam failure information indicating that the problematic antenna panels have experienced beam failure is sent to the base station through the first method among the multiple methods.

[0225] In step S3G, if at least one of the n antenna panels is not a problematic antenna panel, beam failure information indicating that the problematic antenna panel has experienced beam failure is sent to the base station through the second method among the multiple methods.

[0226] The time delay from determining that the problematic antenna panel has experienced beam failure to the ....

[0227] In one embodiment, if all n antenna panels in the user equipment are problematic antenna panels that have experienced beam failure, the user equipment will be unable to communicate with the base station. In this case, based on this embodiment, a first method can be selected to send beam failure information to the base station so that the base station can determine that the problematic antenna panel has experienced beam failure as soon as possible after the beam failure occurs, thereby ensuring that beam failure recovery is performed as soon as possible to restore normal communication between the base station and the user equipment.

[0228] Accordingly, if at least one of the n antenna panels in the user equipment is not a faulty antenna panel, that is, the user equipment can communicate normally with the base station through at least one antenna panel, in this case, based on this embodiment, a second method can be selected to send beam failure information to the base station so that the base station can prioritize restoring the communication of the user equipment that sent beam failure information to the base station in the first method.

[0229] The first and second methods can be selected as needed. For example, the first method could be as follows: Figure 9 or Figure 11 In the embodiment shown, a random access method is initiated to the base station. The second method can be as follows: Figure 2 The embodiment shown illustrates the method of sending beam measurement reports or Figure 4 The embodiment shown illustrates the method for sending MAC CE signaling.

[0230] Figure 15 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 15 As shown, sending beam failure information to the base station to indicate that the problematic antenna panel has experienced beam failure includes multiple methods, including:

[0231] In step S3H, if the usage priority of the problematic antenna panel is higher than the preset priority, a beam failure message indicating that the problematic antenna panel has experienced beam failure is sent to the base station through the first method among the multiple methods.

[0232] In step S3I, if the usage priority of the problematic antenna panel is lower than the preset priority, beam failure information indicating that the problematic antenna panel has experienced beam failure is sent to the base station through the second method among the multiple methods.

[0233] The time delay from determining that the problematic antenna panel has experienced beam failure to the ....

[0234] The usage priority can be pre-configured before the user equipment leaves the factory, or it can be set by the user after the user equipment leaves the factory according to their needs. For example, after a certain antenna panel is replaced, the lifespan of the antenna panel is theoretically relatively long, so its usage priority can be set to be higher. Alternatively, it can be set according to the base station configuration. For example, for user equipment with carrier aggregation, the priority of the antenna panel on the primary cell (Pcell) can be higher than the priority of the antenna panel on the secondary cell (Scell).

[0235] In one embodiment, if a beam failure occurs when a higher-priority antenna panel is used among the n antenna panels in a user equipment (UE), it is more likely to cause communication failures for the UE than when a beam failure occurs when a lower-priority antenna panel is used. For example, if a higher-priority antenna panel belongs to the primary cell of the terminal and a lower-priority antenna panel belongs to the secondary cell of the terminal, and a beam failure occurs when a higher-priority antenna panel fails and is not recovered quickly, the UE will communicate with the base station using a lower-priority antenna panel. This will cause some information that is only transmitted on the primary cell, such as RRC signaling, to fail to be transmitted normally, thereby affecting communication.

[0236] Based on this embodiment, if a beam failure occurs when using an antenna panel with a higher priority (higher than the preset priority), a first method can be selected to send beam failure information to the base station. This will enable the base station to determine that a beam failure has occurred as soon as possible after the problematic antenna panel has failed, thereby ensuring that beam failure recovery is performed as soon as possible so that the user equipment can continue to communicate by using the antenna panel with the higher priority.

[0237] Accordingly, if a beam failure occurs when using an antenna panel with a lower priority (below the preset priority), based on this embodiment, a second method can be selected to send beam failure information to the base station so that the base station can prioritize restoring communication of the user equipment that sent beam failure information to the base station in the first method.

[0238] The first and second methods can be selected as needed. For example, the first method could be as follows: Figure 9 or Figure 11 In the embodiment shown, a random access method is initiated to the base station. The second method can be as follows: Figure 2 The embodiment shown illustrates the method of sending beam measurement reports or Figure 4 The embodiment shown illustrates the method for sending MAC CE signaling.

[0239] Figure 16 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 16 As shown, the beam failure determination method further includes:

[0240] In step S6, a shutdown request is sent to the base station to request the deactivation of the problematic antenna panel;

[0241] In step S7, it is determined whether to deactivate the problematic antenna panel based on the feedback information from the base station.

[0242] In one embodiment, a shutdown request can be sent to the base station to request the deactivation of the problematic antenna panel. Based on the feedback information from the base station, it can be determined whether to deactivate the problematic antenna panel. If it is determined to deactivate the problematic antenna panel, then the problematic antenna panel can be activated.

[0243] Therefore, the problematic antenna panel can be activated based on the feedback information from the base station, thereby preventing the problematic antenna panel from continuing to consume power, saving power for user equipment, and improving the user equipment's performance.

[0244] It should be noted that for carrier aggregation user equipment, if the problematic antenna panel only experiences beam failure on a certain secondary cell, then the antenna panel will only be activated on the frequency band of that secondary cell, and will remain active on other secondary cells or the primary cell.

[0245] If the base station needs to activate the problematic antenna panel when the terminal needs to activate it for service purposes, it needs to resend the activation signaling to the terminal to activate the problematic antenna panel. Alternatively, the terminal can proactively activate the problematic antenna panel for service purposes and send a message to the base station to inform it that the problematic antenna panel has been activated.

[0246] Figure 17 This is a schematic flowchart illustrating yet another beam failure determination method according to embodiments of the present disclosure. Figure 17 As shown, the beam failure determination method further includes:

[0247] In step S8, the problematic antenna panel is deactivated;

[0248] In step S9, a notification message is sent to the base station to notify the base station that the problematic antenna panel has been deactivated.

[0249] In one embodiment, the problematic antenna panel can also be deactivated, and then a notification message can be sent to the base station to notify the base station that the problematic antenna panel has been deactivated.

[0250] Accordingly, the problematic antenna panel can be deactivated, thereby preventing the problematic antenna panel from continuing to consume power, saving power for user equipment, improving user equipment needs, and sending a notification message to the base station to notify the base station that the problematic antenna panel has been deactivated, so that the base station can determine which antenna panels in the user equipment have been deactivated.

[0251] The terminal can also proactively activate the problematic antenna panel as needed and send a message to the base station informing it that the problematic antenna panel has been activated. Alternatively, if the base station activates the problematic antenna panel by the terminal as needed for service purposes, it needs to resend the activation signaling to the terminal to activate the problematic antenna panel.

[0252] Corresponding to the aforementioned embodiments of the beam failure determination method, this disclosure also provides embodiments of the beam failure determination apparatus.

[0253] Figure 18 This is a schematic block diagram illustrating a beam failure determination device according to an embodiment of the present disclosure. The beam failure determination device shown in the embodiment of the present disclosure can be applied to user equipment, such as mobile phones, tablets, wearable devices, vehicle-mounted devices, and other electronic devices.
