Description

Beam processing method, device and readable storage medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 4, 2023, with application number 202310981587.8 and application name “Beam processing method, device and readable storage medium”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a beam processing method, device, and readable storage medium. Background Art

[0003] There are two links between the base station and the network-controlled repeater (NCR), one is the control link and the other is the backhaul link. There is an access link between the NCR and the UE. The NCR adds a control plane protocol stack on the basis of the original repeater. The base station can control some functions of the NCR by sending network control information. In NR R18, the base station is supported to control the beams of the Control link, Backhaul link and Access link. When a beam failure occurs on the Control link, the Backhaul link is also considered to have a beam failure because the transmission path is basically the same as that of the Control link, thereby terminating the data transmission on the Access link. After the Control link beam is recovered, the beam indication information of the Access link also needs to be reconfigured.

[0004] However, in the prior art, when a beam failure occurs on the Control link, data transmission on the Access link is terminated. When the beam is restored, any beam indication information on the Access link needs to be reconfigured to take effect and data transmission can be restored, resulting in a long reconfiguration time and a long data transmission termination time.

[0005] Therefore, the existing technology cannot achieve that when a beam failure occurs on the Control link, the beam of the Access link takes effect quickly when the beam of the Control link is restored.

[0006] Summary of the Invention

[0007] The present disclosure provides a beam processing method, device and readable storage medium, which solves the technical problem in the prior art that when a beam failure occurs on a Control link, the beam of an Access link cannot take effect quickly when the Control link beam is restored.

[0008] In a first aspect, the present disclosure provides a beam processing method, which is applied to a network-controlled repeater (NCR), wherein the NCR is communicatively connected to a base station and a terminal, respectively, and the link between the NCR and the base station includes a control link, and the link between the NCR and the terminal includes an access link. The method includes:

[0009] When a beam failure occurs on the control link, determining whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored, by a predefined method or by receiving configuration information including higher-layer parameters;

[0010] If the beam indication information of the access link does not need to be reconfigured, determining that the beam indication information of the access link after the beam of the control link is restored is the beam indication information of the access link before the beam failure of the control link occurs;

[0011] If the beam indication information of the access link needs to be reconfigured, it is determined that after the beam of the control link is restored, the beam indication information of the access link is the beam indication information of the access link received on the control link after the beam is restored.

[0012] Optionally, the predefined manner or configuration information is obtained from a base station, and determining whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored by the predefined manner or receiving the configuration information containing higher-layer parameters includes:

[0013] Determining, by a predefined manner or by receiving configuration information including higher-layer parameters, whether beam indication information of any access link needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored; or

[0014] According to the predefined method or receiving configuration information containing high-level parameters, determine whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored; wherein, the predefined method or configuration information includes at least one of the following: the type of beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link.

[0015] Optionally, determining whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored by a predefined method or receiving configuration information including higher-layer parameters includes:

[0016] Determining whether it is necessary to reconfigure the time threshold of the beam indication information of the access link by a predefined manner or receiving configuration information including higher-layer parameters;

[0017] Determining a time interval from beam failure to beam recovery of the control link;

[0018] If the time interval is less than or equal to the time threshold, it is determined that after the beam of the control link is restored, it is not necessary to reconfigure the beam indication information of the access link; or, if the time interval is greater than the time threshold, it is determined that after the beam of the control link is restored, it is necessary to reconfigure the beam indication information of the access link.

[0019] In the disclosed embodiment, the NCR determines, by system default (here, configuration by a predefined method) or reading a high-level parameter configuration, whether the beam indication information of the access link before the beam failure can be used after the beam of the control link is restored. Alternatively, the NCR determines, by system default (here, configuration by a predefined method) or reading a high-level parameter configuration, whether the type of the beam indication information of the access link, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link need to be reconfigured after the beam of the control link is restored. This further determines whether the beam indication information of the access link before the beam failure can be used after the beam of the control link is restored. If the beam indication information of the access link before the beam failure cannot be used, the beam of the access link is reconfigured according to the existing process. This solves the problem in the prior art that when a beam failure occurs in the control link, data transmission of the access link is terminated. When the beam is restored, all beam-related information of the access link also needs to be reconfigured before it can take effect and data transmission can be restored, resulting in a long reconfiguration time and a long termination time of data transmission. This solves the problem that when a beam failure occurs in the control link, the beam of the access link is quickly effective when the beam is restored.

[0020] Optionally, the type of the beam indication information of the access link includes periodicity and semi-persistence, and the method further includes:

[0021] If the beam indication information of the access link is periodic beam indication information or semi-persistent beam indication information, and when it is determined that the periodic beam indication information or semi-persistent beam indication information of the access link does not need to be reconfigured, determining a time at which the periodic beam indication information or semi-persistent beam indication information of the access link takes effect after the beam of the control link is restored;

[0025] The starting timeslot of the first complete configuration period of the periodic beam indication information or semi-persistent beam indication information of the access link after the timeslot index after the beam recovery of the control link;

[0026] The time slot index after the beam recovery of the control link does not exceed a fixed time length.

[0027] In an embodiment of the present disclosure, if the system is configured (here referring to configuration through a predefined method or high-level parameter configuration) that the access link beam index of the periodic or semi-persistent indication after the beam recovery of the control link can be reused, the effective time of the periodic beam indication information or semi-persistent beam indication information of the access link after the beam recovery of the control link is determined, and the effective time can be determined in at least one of the following ways: the first time slot after the time slot index after the beam recovery of the control link; the starting time slot of the first complete configuration period of the periodic beam indication information or semi-persistent beam indication information of the access link after the time slot index after the beam recovery of the control link; no more than a fixed time length after the time slot index after the beam recovery of the control link.

[0028] Optionally, the type of the beam indication information of the access link includes aperiodicity, and the method further includes:

[0029] If the beam indication information of the access link is non-periodic beam indication information, and when it is determined that the non-periodic beam indication information of the access link does not need to be reconfigured, determine whether the non-periodic beam indication information of the access link is effective after the beam of the control link is restored.

[0030] Optionally, determining whether the aperiodic beam indication information of the access link is effective after the beam of the control link is restored includes:

[0031] If the time slot index of the time domain resource configured in the aperiodic beam indication information of the access link is less than or equal to the time slot index after the beam of the control link is restored, it is determined that the aperiodic beam indication information of the access link is no longer effective after the beam of the control link is restored, and the aperiodic beam indication information of the access link after the beam of the control link is restored is deleted; or,

[0032] If the time slot index of the time domain resource configured in the non-periodic beam indication information of the access link is greater than the time slot index after the beam of the control link is recovered, it is determined that the non-periodic beam indication information of the access link takes effect after the beam of the control link is recovered, or it is determined that the non-periodic beam indication information of the access link takes effect at the determined effective time after the beam of the control link is recovered.

[0033] In an embodiment of the present disclosure, if the system (here referring to configuration through a predefined method or high-level parameter configuration) configures the access link beam index of the non-periodic indication after the beam recovery of the control link can be reused: assuming that the time slot (symbol) index at which the beam recovery of the control link is completed is n, when the time slot (symbol) index of the time domain resource configuration in the reused non-periodic indication beam information (here referring to the non-periodic beam indication information, that is, the beam indication information of the access link configured before the beam failure occurs) is less than or equal to n, the indication is no longer effective; if it is greater than n, the indication is effective.

[0034] Optionally, the method further includes:

[0035] If the beam indication information of the access link does not need to be reconfigured, retaining the beam indication information of the access link before the beam failure of the control link occurs;

[0038] In the disclosed embodiment, if a beam failure occurs on the control link and the NCR terminates data transmission on the access link, the NCR retains the beam indication information of the access link before the beam failure that can be reused (or used) based on the beam indication information obtained in the above embodiment. Furthermore, the NCR releases the beam indication information of the access link that can no longer be used to ensure that the beam of the access link takes effect quickly when the beam is restored after a beam failure occurs on the control link.

[0039] In a second aspect, the present disclosure provides a beam processing method, applied to a base station, wherein the base station is communicatively connected to a network-controlled repeater NCR, the NCR is communicatively connected to a terminal, and the link between the NCR and the base station includes a control link, and the link between the NCR and the terminal includes an access link. The method includes:

[0040] Sending configuration information to the NCR, where the configuration information is predefined configuration information or a high-layer parameter; the configuration information is used to indicate to the NCR whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored;

[0041] If the configuration information is used to indicate that the beam indication information of the access link does not need to be reconfigured, then the configuration information configures the NCR to use the beam indication information of the access link as the beam indication information of the access link before the beam failure of the control link occurs after the beam of the control link is restored; or

[0042] If the configuration information is used to indicate that the beam indication information of the access link needs to be reconfigured, then when a beam failure occurs in the control link, the beam recovery of the control link is performed, and the NCR is configured through the configuration information so that after the beam recovery of the control link, the beam indication information of the access link is the beam indication information of the access link sent on the control link after the beam recovery.

[0043] Optionally, the configuration information is used to indicate whether the NCR needs to reconfigure the beam indication information of the access link after the beam of the control link is restored, including:

[0044] The configuration information is used to indicate whether beam indication information of any access link needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored; or,

[0045] The configuration information is used to indicate at least one of the following: whether the type of beam indication information of the access link needs to be reconfigured after the beam of the control link is restored, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link.

[0046] Optionally, the configuration information is used to indicate whether the NCR needs to reconfigure the beam indication information of the access link after the beam of the control link is restored, including:

[0047] If the time interval is less than or equal to the time threshold, the configuration information is used to indicate that after the beam of the control link is restored, it is not necessary to reconfigure the beam indication information of the access link; or,

[0048] If the time interval is greater than the time threshold, the configuration information is used to indicate that after the beam of the control link is restored, the beam indication information of the access link needs to be reconfigured;

[0049] The time threshold is a time threshold for determining whether the beam indication information of the access link needs to be reconfigured, and the time interval is a time interval from beam failure to beam recovery of the control link.

[0050] In the embodiment of the present disclosure, the base station indicates, through system default (here referring to configuration through a predefined method) or reading high-level parameter configuration, whether the NCR can use the beam indication information of the access link before the beam failure after the beam of the control link is restored, or, through system default (here referring to configuration through a predefined method) or reading high-level parameter configuration, indicates one to multiple combinations of the type of beam indication information of the access link, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link that the NCR needs to reconfigure after the beam of the control link is restored, thereby indicating whether the NCR can use the beam indication information of the access link before the beam failure after the beam of the control link is restored; if the NCR is instructed not to use the beam indication information of the access link before the beam failure, the base station reconfigures the beam of the access link according to the existing process, and sends the configured beam indication information of the access link to the NCR. The present invention solves the problem in the prior art that when a beam failure occurs in the control link, the data transmission of the access link is terminated. When the beam is restored, the beam-related information of any access link also needs to be reconfigured to take effect and the data transmission can be restored, resulting in a long reconfiguration time and a long termination time of the data transmission.

[0063] If the time slot index of the time domain resource configured in the non-periodic beam indication information of the access link is greater than the time slot index after the beam of the control link is recovered, it is determined that the configuration information is used to indicate that the non-periodic beam indication information of the access link takes effect after the beam of the control link is recovered, or is used to indicate that the non-periodic beam indication information of the access link takes effect at a determined effective time after the beam of the control link is recovered.

[0064] In an embodiment of the present disclosure, if the system (here referring to configuration through a predefined method or high-level parameter configuration) configures the access link beam index of the non-periodic indication after the beam recovery of the control link can be reused: assuming that the time slot (symbol) index at which the beam recovery of the control link is completed is n, when the time slot (symbol) index of the time domain resource configuration in the reused non-periodic indication beam information (here referring to the non-periodic beam indication information, that is, the beam indication information of the access link configured before the beam failure occurs) is less than or equal to n, the indication is no longer effective; if it is greater than n, the indication is effective.

[0100] In this disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0101] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0102] In order to clearly understand the technical solution of the present disclosure, the solution of the prior art is first introduced in detail. The main difference between the network-controlled repeater NCR and the traditional relay is that the base station can perform network control on the NCR serving it. Referring to Figure 1, Figure 1 shows the link relationship between the base station (for example, gNB, i.e., 5G base station), NCR and terminal (English: User Equipment, UE); there are two links between the base station and NCR, one is the control link and the other is the backhaul link; there is a link between NCR and UE as the access link; the MT in NCR-MT shown in Figure 1 is Mobile termination, and Mobile termination refers to the mobile terminal; the Fwd in NCR-Fwd is Forwarding, and Forwarding refers to forwarding.

[0103] In the NCR project of NR Release 18, the base station supports beam control of the control link, backhaul link, and access link. When a beam failure occurs on the control link, the backhaul link is also considered to have experienced a beam failure because the transmission path is basically the same as the control link, thus terminating data transmission on the access link. After the control link beam is recovered, the access link beam information also needs to be reconfigured.

[0104] The existing standard conclusions support three types of beam indication information for access links: periodic beam indication information (here refers to periodic beam indication information), semi-persistent beam indication information (here refers to semi-persistent beam indication information) and aperiodic beam indication information (here refers to aperiodic beam indication information).

[0105] However, the existing technology does not distinguish the types of beam indication information. When a beam failure occurs in the control link, the data transmission of the access link is terminated; when the control link beam is restored, the beam-related information of the access link also needs to be reconfigured to take effect and data transmission can be restored, resulting in a long reconfiguration time and a long data transmission termination time.

[0106] Therefore, the existing technology cannot achieve that when a beam failure occurs in the control link, the beam of the access link is quickly effective when the control link beam is restored.

[0107] The inventors further studied and found that, considering that the beam indication of the access link has three types: periodic beam indication information, semi-persistent beam indication information and non-periodic beam indication information, different types of beam indication configuration time are different, and the beam configuration of the access link can be optimized. For example, in some cases, the configuration before the beam failure can be retained, so that when the beam failure of the control link occurs, the beam of the access link can take effect quickly when the beam of the control link is restored.

[0108] Therefore, based on the creative research of the above inventors, the beam processing method proposed in the present disclosure is proposed. In the present disclosure, the base station instructs the NCR whether the access link beam needs to be reconfigured after the beam of the control link is restored through system default or high-level parameter configuration, or the NCR determines whether the access link beam needs to be reconfigured after the beam of the control link is restored through a predefined method or high-level parameter configuration information obtained by the base station. If reconfiguration is not required, the access link directly uses the beam indication information of the access link before the C-link beam fails; if reconfiguration is required, according to the existing process, the base station configures the beam indication information of the access link and instructs the NCR to determine that the beam indication information of the access link after the beam of the control link is restored is the beam indication information of the access link sent on the control link after the beam is restored. The present invention solves the problem in the prior art that when a beam failure occurs in the control link, the data transmission of the access link is terminated. When the beam is restored, the beam of any access link is not distinguished, and the beam-related information of the access link also needs to be reconfigured to take effect and the data transmission can be restored, resulting in a long reconfiguration time and a long termination time of the data transmission. The invention realizes that when a beam failure occurs in the control link, the beam of the access link takes effect quickly when the beam is restored.

[0109] As shown in FIG2 , FIG2 is an interactive diagram of a beam processing method provided by an embodiment of the present disclosure. As shown in FIG2 , in an embodiment of the present disclosure, a base station determines indication information by a predefined method or by configuring high-level parameters, and sends the indication information to an NCR. The indication information includes configuration information of the predefined method or high-level parameters; the NCR performs beam processing based on the predefined method or high-level parameter configuration information (indication information), i.e., determines whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored. If it is not necessary to reconfigure the beam indication information of the access link, the beam indication information of the access link after the beam of the control link is restored is determined to be the beam indication information of the access link before the beam failure of the control link occurs; if it is necessary to reconfigure the beam indication information of the access link, the beam indication information of the access link after the beam of the control link is restored is determined to be the beam indication information of the access link received on the control link after the beam is restored; wherein, the base station reconfigures the beam indication information of the access link according to the existing process and sends it to the NCR.

[0110] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0111] FIG3 is a flow chart illustrating a beam processing method according to an embodiment of the present disclosure. As shown in FIG3 , the beam processing method according to this embodiment is performed by an NCR, which is in communication with a base station and a terminal, respectively. The link between the NCR and the base station comprises a control link, and the link between the NCR and the terminal comprises an access link. The beam processing method according to this embodiment of the present disclosure includes the following steps:

[0112] Step 301: When a beam failure occurs in the control link, determine whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored through a predefined method or by receiving configuration information containing high-level parameters.

[0113] The configuration information of the predefined mode or high-layer parameters may be obtained from indication information received from the base station, or may be sent by other terminals, which is not specifically limited here.

[0114] Among them, when the beam failure of the control link occurs, the NCR can determine whether the access link beam needs to be reconfigured after the beam of the control link is restored through system default or high-level parameter configuration.

[0115] Step 302: If the beam indication information of the access link does not need to be reconfigured, determine that the beam indication information of the access link after the beam of the control link is restored is the beam indication information of the access link before the beam failure of the control link occurs.

[0116] Step 303: If the beam indication information of the access link needs to be reconfigured, determine that the beam indication information of the access link after the beam of the control link is restored is the beam indication information of the access link sent on the control link after the beam is restored.

[0117] If reconfiguration is not required, the access link directly uses the beam of the access link before the control link beam failure. If reconfiguration is required, the access link beam is reconfigured according to the existing process; for example, time domain resources and beam indication information, as well as the addition, modification, and release status, are configured through RRC parameters; time domain resources and beam indication candidate sets are configured through RRC parameters, and the activation status is configured through MAC-CE; time domain resources and beam indication candidate sets are configured through RRC parameters, and the current parameters are indicated through DCI, that is, beam indication information is indicated through DCI.

[0118] Therefore, the present disclosure determines whether the access link beam needs to be reconfigured after the beam of the control link is restored by a predefined method or a method of receiving a configuration including high-level parameters. If reconfiguration is not required, the access link directly uses the beam indication information of the access link before the beam failure of the control link occurs; if reconfiguration is required, the beam indication information of the access link is reconfigured according to the existing process. This solves the problem in the prior art that when a beam failure occurs in the control link, the data transmission of the access link is terminated, and when the beam is restored, the beam-related information of any access link also needs to be reconfigured to take effect and the data transmission can be restored, resulting in a long reconfiguration time and a long termination time of the data transmission. This solves the problem that when a beam failure occurs in the control link, the beam of the access link takes effect quickly when the beam is restored.

[0119] Optionally, the predefined manner or configuration information is obtained from a base station, and determining whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored by the predefined manner or receiving the configuration information containing higher-layer parameters includes:

[0120] Determining, by a predefined manner or by receiving configuration information including higher-layer parameters, whether beam indication information of any access link needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored; or

[0121] According to the predefined method or receiving configuration information containing high-level parameters, determine whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored; wherein, the predefined method or configuration information includes at least one of the following: the type of beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link.

[0122] Optionally, the configuration method includes one or more of the following: radio resource control RRC configuration, media access control control unit MAC-CE activation, and downlink control information DCI indication.

[0123] Determining whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored by at least one of the following methods:

[0124] Method 1: Determine by system default or through high-level parameter configuration

[0125] By a predefined method or receiving configuration information including high-layer parameters, it is determined whether the beam indication information of any access link needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored.

[0126] Specifically, if the configuration information does not include information indicating which type of beam indication information, which configuration mode of the beam indication information, or which priority of the beam indication information does not need to be reconfigured or needs to be reconfigured, then the beam indication information of all access links cannot be used for the forwarding link after the beam of the control link is restored, or vice versa, that is, the beam indication information of all access links can be used for the forwarding link after the beam of the control link is restored. The base station can be configured in a predefined manner or high-level parameters to indicate that the beam indication information of any of the access links needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored. Therefore, the NCR can obtain the indication from the configuration information.

[0127] Method 2: Determine based on the type of beam indication information

[0128] Determine, by a predefined method or by receiving configuration information containing high-level parameters, whether the type of beam indication information of the access link needs to be reconfigured after the beam of the control link is restored; compare the type of beam indication information of the access link with the type of beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored, and determine whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0129] Specifically, whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored is determined according to the type of the beam indication information of the access link. For example, for periodic beam indication information and semi-persistent beam indication information, the access link beam does not need to be reconfigured; for non-periodic beam indication information, the access link beam needs to be reconfigured. Among them, the specific types of beam indication information that need to be reconfigured can also be configured by system default or through high-level parameters. For beam indication information that does not need to be reconfigured, the access link directly uses the beam indication information of the access link before the beam failure of the control link occurs.

[0130] Method 3: Determine based on the method used to configure parameters

[0131] Determine, by a predefined method or by receiving configuration information containing high-level parameters, whether the configuration method of the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored; compare the configuration method of the beam indication information of the access link with the configuration method of the beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored, and determine whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0132] Specifically, the configuration parameters of the access link beam indication are used to determine whether the access link beam needs to be reconfigured after the control link beam is restored. For example, the parameter information configured by RRC does not need to be reconfigured; the information configured by MAC-CE and DCI does need to be reconfigured. The specific configuration parameters that need to be reconfigured can also be determined by system default or by high-level parameter configuration. For beam indication information that does not require reconfiguration, the access link directly uses the beam indication information of the access link before the control link beam failure occurs.

[0133] Method 4: Determine based on the priority in the beam indication information

[0134] Determine the priority of the beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored by a predefined method or by receiving configuration information containing high-level parameters; compare the priority of the beam indication information of the access link with the priority of the beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored, and determine whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0135] Specifically, whether the access link beam needs to be reconfigured after the control link beam is restored is determined based on the priority of the access link beam indication information. For periodic beam indication beam information and semi-persistent beam indication information, there is priority information to distinguish high priority from low priority. Therefore, the priority information can be used to determine whether the access link beam indication information needs to be reconfigured. For example, for high-priority beams, reconfiguration is not required; for low-priority beams, reconfiguration is required. Among them, which specific priorities need to be reconfigured can also be configured by system default or through high-level parameters. For beam indication information that does not need to be reconfigured, the access link directly uses the beam indication information of the access link before the control link beam failure occurs.

[0136] In addition, the priority of the beam indicated in the non-periodic beam indication information can be configured by system default or through high-level parameters. For example, the beams indicated in the non-periodic beam indication information are all high priority or all low priority. For high-priority beams, no reconfiguration is required; for low-priority beams, reconfiguration is required.

[0137] Optionally, determining whether it is necessary to reconfigure the beam indication information of the access link after the beam of the control link is restored by a predefined method or receiving configuration information containing high-layer parameters may also be determined by:

[0138] Method 5: Determine based on the time interval from beam failure to beam recovery

[0139] Determining whether it is necessary to reconfigure the time threshold of the beam indication information of the access link by a predefined manner or receiving configuration information including higher-layer parameters;

[0140] Determine the time interval from beam failure to beam recovery on the control link;

[0141] If the time interval is less than or equal to the time threshold, it is determined that the beam indication information of the access link does not need to be reconfigured after the beam of the control link is restored; or, if the time interval is greater than the time threshold, it is determined that the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0142] Specifically, whether the access link beam needs to be reconfigured is determined based on whether the time interval from beam failure to beam recovery on the control link exceeds a threshold (herein, the time threshold). If the threshold is exceeded, the access link beam indication information needs to be reconfigured. If the threshold is not exceeded, the access link beam indication information does not need to be reconfigured. The specific threshold value can also be configured by system default or through high-level parameters. For beam indications that do not require reconfiguration, the access link directly uses the beam indication information of the access link before the control link beam failure occurred.

[0143] It should be noted that the above-described methods 1 to 5 can be used in any combination to achieve configurable flexibility in determining whether the access link beam needs to be reconfigured when the control link beam is restored after a control link beam failure occurs. The above-described methods are used to distinguish the access link beams and determine which beams require reconfiguration and which do not. Therefore, the problem in the prior art where, upon beam restoration, the beam indication information of any access link must be reconfigured before it can take effect and data transmission can resume, resulting in a long reconfiguration time and a long data transmission termination time, is solved. Furthermore, the access link beam can be quickly made effective when the control link beam is restored after a control link beam failure occurs.

[0144] In the disclosed embodiment, the NCR determines, by system default (here, configuration by a predefined method) or reading a high-level parameter configuration, whether the beam indication information of the access link before the beam failure can be used after the beam of the control link is restored. Alternatively, the NCR determines, by system default (here, configuration by a predefined method) or reading a high-level parameter configuration, whether the type of the beam indication information of the access link, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link need to be reconfigured after the beam of the control link is restored. This further determines whether the beam indication information of the access link before the beam failure can be used after the beam of the control link is restored. If the beam indication information of the access link before the beam failure cannot be used, the beam of the access link is reconfigured according to the existing process. This solves the problem in the prior art that when a beam failure occurs in the control link, data transmission of the access link is terminated. When the beam is restored, all beam-related information of the access link also needs to be reconfigured before it can take effect and data transmission can be restored, resulting in a long reconfiguration time and a long termination time of data transmission. This solves the problem that when a beam failure occurs in the control link, the beam of the access link is quickly effective when the beam is restored.

[0145] Optionally, the method further includes:

[0146] If the beam indication information of the access link does not need to be reconfigured, retaining the beam indication information of the access link before the beam failure of the control link occurs;

[0147] If the beam indication information of the access link needs to be reconfigured, the beam indication information of the access link before the beam failure occurs in the control link is cleared.

[0148] Specifically, after a beam failure occurs in the control link, the beam indication information that is not reconfigured will be retained, and the remaining beam indication information will be cleared. The NCR can directly determine the beam indication information of the access link using the retained beam indication information of the access link before the beam failure occurs in the control link. The processing logic is clear and simple.

[0149] Optionally, the type of the beam indication information of the access link includes periodicity and semi-persistence, and the method further includes:

[0150] If the beam indication information of the access link is periodic beam indication information or semi-persistent beam indication information, and when it is determined that the periodic beam indication information or semi-persistent beam indication information of the access link does not need to be reconfigured, determining a time at which the periodic beam indication information or semi-persistent beam indication information of the access link takes effect after the beam of the control link is restored;

[0151] Instruct the physical layer to start forwarding data on the access link after the validation time.

[0152] Among them, for periodic beam indication information and semi-persistent beam indication information, the effective time of the periodic beam indication information or semi-persistent beam indication information of the access link before the beam of the control link is reused after the beam of the control link is recovered can be determined through the system default or high-level parameter configuration information.

[0153] Specifically, if the system is configured so that the beam index corresponding to the beam of the access link that is periodically or semi-continuously indicated after the control link beam is recovered can be reused, the time slot (symbol) index at which the control link beam recovery is completed is used to determine the effective time of the periodic beam indication information or semi-continuous beam indication information of the access link after the control link beam is recovered, and the physical layer is instructed to start data forwarding on the access link in the time slot (symbol) where the beam index information exists after the effective time, to ensure that the beam of the access link can take effect quickly when the control link beam is recovered.

[0154] Optionally, determining the effective time of the periodic beam indication information or the semi-persistent beam indication information of the access link after the beam of the control link is restored includes any one of the following:

[0155] Determining the validation time according to the first time slot after the time slot index after the beam of the control link is restored;

[0156] Determining the taking effect time according to the starting time slot of the first complete configuration period of the periodic beam indication information or the semi-persistent beam indication information of the access link after the time slot index after the beam of the control link is restored;

[0157] The effective time is determined based on a time slot index after the beam of the control link is restored that does not exceed a fixed time length.

[0158] Specifically, the time slot determined in the following manner is used to determine the effective time (see FIG4 ):

[0159] Mode 10: the first time slot (symbol) after the time slot (symbol) in which the beam recovery of the control link is completed; for example, at any moment or specified moment in the first time slot.

[0160] Method 20: After the time slot (symbol) in which the beam recovery of the control link is completed, the starting time slot (symbol) of the first complete configuration cycle of the beam indication information of the access link; for example, the starting time of the starting time slot or any time or other specified time.

[0161] Mode 30: The beam recovery of the control link is completed no later than a fixed time duration, such as 1 ms, after the time slot (symbol) when the beam recovery is completed. For example, at any time or a specified time within the fixed time duration.

[0162] Therefore, through the above methods 10 to 30, it is possible to ensure that the beam of the access link can take effect quickly when the control link beam is restored, while achieving the flexibility of configurable effectiveness time.

[0163] Optionally, the type of the beam indication information of the access link includes aperiodicity, and the method further includes:

[0164] If the beam indication information of the access link is non-periodic beam indication information, and when it is determined that the non-periodic beam indication information of the access link does not need to be reconfigured, determine whether the non-periodic beam indication information of the access link is effective after the beam of the control link is restored.

[0165] Among them, for the non-periodic beam indication information, the system default or high-level parameter configuration information can be used to determine whether the non-periodic beam indication information of the access link before the control link beam is reused after the control link beam is recovered is effective.

[0166] Since the beam indication information of the access link before the control link beam is generated is non-periodic, the following scenario may exist: although the system is configured to reuse the beam indication information of the access link before the control link beam is generated, the non-periodic beam indication information may have expired before the beam of the control link is restored. Therefore, it is necessary to determine whether the beam indication information of the access link before the control link beam is generated that can be reused is invalid or valid to ensure that the data on the access link can be forwarded normally after the beam of the control link is restored.

[0167] Optionally, determining whether the aperiodic beam indication information of the access link is effective after the beam of the control link is restored includes:

[0168] If the time slot index of the time domain resource configured in the aperiodic beam indication information of the access link is less than or equal to the time slot index after the beam of the control link is restored, it is determined that the aperiodic beam indication information of the access link is no longer effective after the beam of the control link is restored, and the aperiodic beam indication information of the access link after the beam of the control link is restored is deleted; or

[0169] If the time slot index of the time domain resource configured in the non-periodic beam indication information of the access link is greater than the time slot index after the beam of the control link is recovered, it is determined that the non-periodic beam indication information of the access link takes effect after the beam of the control link is recovered, or it is determined that the non-periodic beam indication information of the access link takes effect at the determined effective time after the beam of the control link is recovered.

[0170] Specifically, if the system is configured so that the beam index corresponding to the beam of the access link indicated non-periodically after the beam recovery of the control link can be reused: assuming that the time slot (symbol) index at which the beam recovery of the control link is completed is n, when the time slot (symbol) index of the time domain resource configuration in the beam indication information of the reused non-periodic indication (i.e., the beam indication information of the access link configured before the beam failure occurs) is less than or equal to n, the indication is no longer effective; if it is greater than n, the indication is effective.

[0171] The following describes the beam processing method in detail, taking the process of the NCR determining the beam indication information of the access link after the beam of the control link is restored as an example:

[0172] Step a1: The NCR determines the beam indication information of the access link before the beam failure that can be used after the beam of the control link is restored, by system default or by reading high-level parameter configuration. The beam indication information should include but is not limited to one or more of the following combinations:

[0173] Types of beam indication information that can be reused (multiple choices): periodic, semi-persistent, dynamic (e.g., non-periodic).

[0174] Reusable priorities: All, High Priority, Low Priority.

[0175] Reusable configuration parameters (multiple selections possible): RRC parameters, MAC-CE parameters, and DCI configuration.

[0176] It should be noted that: if the above information is not configured, the beam information of all access links cannot be used in the forwarding link after the control link beam is restored, or vice versa, that is, the beam information of all access links can be used in the forwarding link after the C-link beam is restored.

[0177] Step b1: After a beam failure occurs in the control link, the NCR terminates data transmission on the access link. The NCR retains the beam indication information of the access link before the beam failure that can be reused according to the method obtained in step a); and releases the beam indication information of the access link that can no longer be used.

[0178] In step c1, after the control link beam is restored, the NCR, based on the method obtained in step a1, validates the beam indication information of the access link before the beam failure that can be reused at the specified validation time (here, the validation start time). After the validation time, the access link begins data forwarding in the time slots (symbols) where the beam index information exists (e.g., the time slot containing the validation time or a time slot containing a later time).

[0179] For periodic or semi-persistent beam indication information, the method for specifying the effective time can be:

[0180] The first time slot (symbol) after the time slot (symbol) in which C-link beam recovery is completed.

[0181] After the time slot (symbol) in which the C-link beam recovery is completed, the starting time slot (symbol) of the first complete configuration cycle determined by the access link beam indication information is accessed.

[0182] The time slot (symbol) after which the C-link beam recovery is completed shall be no later than a fixed time, such as 1 ms.

[0183] For non-periodic beam indication information, the method for determining whether it is effective is:

[0184] When the time slot (symbol) index of the time domain resource configuration in the beam indication information of the reusable non-periodic indication (i.e., the beam indication information of the access link configured before the beam failure occurs) is less than or equal to the time slot (symbol) index at the beam recovery moment, the indication is no longer effective; if it is greater than the time slot (symbol) index at the beam recovery moment, the indication is effective.

[0185] For example, in the first embodiment, the beam processing method is described in detail below by taking one or a combination of methods 2 to 4 as an example.

[0186] Step 1: The configuration information configured by the system default or high-level parameter configuration method determines one or more of the type of access link beam indication information, configuration parameter method, and priority that do not need to be reconfigured after the beam of the control link is restored; for example: the beam indication information of the access link that is semi-persistent and configured with a high priority, its RRC configuration information does not need to be reconfigured, and the MAC-CE activation information needs to be re-indicated.

[0187] Step 2: After a beam failure occurs in the control link, the beam indication information that will not be reconfigured is retained, and the remaining beam indication information is cleared;

[0188] Step 3: After the beam of the control link is restored, the retained beam indication information that is not reconfigured will take effect at the effective time specified by the system.

[0189] Step 4: After the control link beam is restored, the base station resends the beam indication information to the NCR to configure the access link beam index that needs to be reconfigured.

[0190] For example, in the second embodiment, the beam processing method is described in detail below by taking one or a combination of method 1 and method 2 to method 4 as an example.

[0191] Step 1: Determine whether the access link beam needs to be reconfigured after the control link beam is restored according to the above method 1;

[0192] Step 2: If reconfiguration is required, execute Step 5; if reconfiguration is not required, determine one or more of the types, configuration parameters, and priorities of the access link beam indication information that do not need to be reconfigured after the beam of the control link is restored through system default or high-level parameter configuration; for example, the beam indication information of the access link that is semi-persistent and configured with a high priority does not require reconfiguration of its RRC parameters, but the MAC-CE activation information needs to be re-indicated.

[0193] Step 3: After a control link beam failure occurs, the beam indication information that is not reconfigured is retained, and the remaining beam indication information is cleared.

[0194] Step 4: After the beam of the control link is restored, the retained beam indication information that is not reconfigured will take effect at the effective time specified by the system.

[0195] Step 5: After the control link beam is restored, the base station resends the beam indication information to the NCR to configure the access link beam index that needs to be reconfigured.

[0196] For example, in the third embodiment, the beam processing method is described in detail below by taking the combination of method 5 and one or more of methods 2 to 4 as an example.

[0197] Step 1: Determine one or more of the type, configuration parameters, and priority of the beam indication information of the access link that does not need to be reconfigured after the beam of the control link is restored through system default or high-level parameter configuration; for example: the beam indication information of the access link that is semi-persistent and configured with a high priority, its RRC parameters do not need to be reconfigured, and the MAC-CE activation information needs to be re-indicated.

[0198] Step 2: Determine the time interval threshold from beam failure to beam recovery that does not require reconfiguration after beam recovery of the control link through system default or high-level parameter configuration.

[0199] Step 3: After a control link beam failure occurs, the beam indication information that is not reconfigured is retained, and the remaining beam indication information is cleared.

[0200] Step 4: After the control link beam is restored, if the interval from beam failure to beam restoration does not exceed the threshold, the retained beam indication information will be activated at the system-specified activation time. If the interval from beam failure to beam restoration exceeds the threshold, the retained beam indication information will be cleared.

[0201] Step 5: After the control link beam is restored, the base station resends the beam indication information to the NCR to configure the access link beam index that needs to be reconfigured.

[0202] For example, in the fourth embodiment, the beam processing method is described in detail below by taking the combination of method 1 and method 5 as an example.

[0203] Step 1: Determine whether the access link beam needs to be reconfigured after the control link beam is restored according to method 1;

[0204] Step 2: If reconfiguration is required, proceed to Step 4; if not, proceed to Step 3.

[0205] Step 3: Determine the time interval threshold between beam failure and beam recovery that does not require reconfiguration after control link beam recovery, either through system default or high-level parameter configuration. After a C-link beam failure occurs, the beam indication information is retained. After C-link beam recovery, if the time interval between beam failure and beam recovery does not exceed the threshold, the retained beam indication information that does not require reconfiguration takes effect at the system-specified time. If the time interval between beam failure and beam recovery exceeds the threshold, the retained beam indication information that does not require reconfiguration is cleared.

[0206] Step 4: After the control link beam is restored, the base station resends the beam indication information to the NCR to configure the access link beam index that needs to be reconfigured.

[0207] For example, in the fifth embodiment, the beam processing method is described in detail below by taking the combination of method 1 and method 5 and one or more methods from method 2 to method 4 as an example.

[0208] Step 1: Determine whether the access link beam needs to be reconfigured after the control link beam is restored according to method 1;

[0209] Step 2: If reconfiguration is performed, execute Step 6; if reconfiguration is not performed, determine one or more of the type, configuration parameters, and priority of the beam indication information of the access link that does not need to be reconfigured after the beam of the control link is restored through system default or high-level parameter configuration. For example, the beam indication information of the access link that is semi-persistent and has a high priority configuration does not need to be reconfigured, but the MAC-CE activation information needs to be re-indicated.

[0210] Step 3: Determine the time interval threshold from beam failure to beam recovery that does not require reconfiguration after C-link beam recovery through system default or high-level parameter configuration.

[0211] Step 4: After a control link beam failure occurs, the beam indication information that is not reconfigured is retained, and the remaining beam indication information is cleared.

[0212] Step 5: After the control link beam is restored, if the interval from beam failure to beam restoration does not exceed the threshold, the retained beam indication information will be activated at the system-specified activation time. If the interval from beam failure to beam restoration exceeds the threshold, the retained beam indication information will be cleared.

[0213] Step 6: After the control link beam is restored, the base station resends the beam indication information to the NCR to configure the access link beam index that needs to be reconfigured.

[0214] It should be noted that if the type of the UE is NCR, the steps of any embodiment of the above method are executed, and the specific implementation method is not repeated here.

[0215] In actual applications, the 38.321 standard handles access link beam failure after a control link beam failure:

[0216] 1> If the UE type is NCR;

[0217] 2> Stop all timeslot forwarding of NCR AC-link

[0218] 2> (Optional) Cancel the beam indication information indicated by SCI. If the upper layer is not configured to retain the beam indication information indicated by SCI

[0219] Note: If retained, the beam indication information can continue to be used after the beam is restored.

[0220] 2> (Optional) Cancel the semi-static beam indication information (optional: priority information) indicated by MAC-CE. If the upper layer is not configured to retain the beam indication information indicated by MAC-CE

[0221] Note: If retained, the beam indication information can continue to be used after the beam is restored.

[0222] 2> (Optional) Cancel the periodic beam indication information (optional: priority information) indicated by RRC. If the upper layer is not configured to retain the beam indication information indicated by RRC

[0223] Note: If retained, the beam indication information can continue to be used after the beam is restored.

[0224] In addition, the processing methods include:

[0225] 3> If there is any beam configuration information (all configurations not released when the beam is restored)

[0226] 4> Instruct the physical layer to start AC-link forwarding, and the forwarding start time is XXX (the three methods 10 to 30 above: the first time slot (symbol) after the beam failure recovery is completed; the first cycle start time slot (symbol) after the beam failure recovery is completed; no later than 1ms after the beam failure recovery is completed).

[0227] The 38.213 standard describes how to handle access link beam failure after a control link beam failure occurs:

[0228] NCR-FWD is sent or received only after the NCR-MT receives an indication of one or more beams [20, TS 38.106] for the NCR-FWD to use for transmission or reception on the corresponding one or more time resources on the access link. When the NCR-MT performs the link recovery procedure described in Chapter 6, the NCR-FWD will not send or receive until the link recovery procedure is completed, unless the upper layer configures the NCR to reuse the beam configuration of the access link before the link failure occurs. If the upper layer configures the NCR to reuse the beam configuration of the access link before the link failure occurs:

[0229] For periodic and semi-continuous beam configurations, the effective time of the beam configuration is XXX (the three methods 10 to 30 mentioned above: the first time slot (symbol) after the beam failure recovery is completed; the first period starting time slot (symbol) after the beam failure recovery is completed; no later than 1ms after the beam failure recovery is completed).

[0230] For non-periodic beam configuration, if the time slot (symbol) index of the time domain resource configuration is less than or equal to the time slot (symbol) index at the beam recovery moment, the indication is no longer effective; if it is greater than the time slot (symbol) index at the beam recovery moment, the indication is effective.

[0231] Therefore, the present disclosure provides a beam processing method, which enables the access link beam to take effect quickly when the beam is restored after a beam failure occurs in the control link, thereby solving the problems of long access link beam reconfiguration time, long data transmission termination time, and poor user experience.

[0232] FIG5 is a flow chart of a beam processing method provided by another embodiment of the present disclosure. As shown in FIG5 , the execution subject of the beam processing method provided by this embodiment is a base station, the base station is in communication connection with a network-controlled repeater NCR, the NCR is in communication connection with a terminal, and the link between the NCR and the base station includes a control link, and the link between the NCR and the terminal includes an access link. The beam processing method provided by this embodiment of the present disclosure includes the following steps:

[0233] Step 501: Send configuration information to the NCR, where the configuration information is predefined configuration information or high-layer parameters; the configuration information is used to indicate to the NCR whether to reconfigure the beam indication information of the access link after the beam of the control link is restored;

[0234] If the configuration information is used to indicate that the beam indication information of the access link does not need to be reconfigured, then the configuration information configures the NCR to use the beam indication information of the access link as the beam indication information of the access link before the beam failure of the control link occurs after the beam of the control link is restored; or

[0235] If the configuration information is used to indicate that the beam indication information of the access link needs to be reconfigured, then when a beam failure occurs in the control link, the beam recovery of the control link is performed, and the NCR is configured through the configuration information so that after the beam recovery of the control link, the beam indication information of the access link is the beam indication information of the access link sent on the control link after the beam recovery.

[0236] In the embodiment of the present disclosure, the base station performs parameter configuration in a predefined manner or by configuring high-level parameters, and instructs the NCR whether it needs to reconfigure the configuration information of the beam indication information of the access link after the beam of the control link is restored. If reconfiguration is not required, the access link directly uses the beam of the access link before the beam failure of the control link occurs. If reconfiguration is required, the beam of the access link is reconfigured according to the existing process; for example: configuring the time domain resources and beam indication information and the status of addition, modification, and release through RRC parameters; configuring the time domain resources and beam indication candidate set through RRC parameters, and configuring the activation status through MAC-CE; configuring the time domain resources and beam indication candidate set through RRC parameters, and indicating the currently used parameters through DCI, that is, indicating the beam indication information through DCI.

[0237] Therefore, the present disclosure instructs the NCR whether the access link beam needs to be reconfigured after the beam of the control link is restored, through a predefined method or a high-level parameter configuration method. If reconfiguration is not required, the access link directly uses the beam indication information of the access link before the beam failure of the control link occurs; if reconfiguration is required, the beam indication information of the access link is reconfigured according to the existing process. This solves the problem in the prior art that when the beam failure of the control link occurs, the data transmission of the access link is terminated, and when the beam is restored, the beam-related information of any access link also needs to be reconfigured to take effect and the data transmission can be restored, resulting in a long reconfiguration time and a long termination time of data transmission. This solves the problem that when the beam failure of the control link occurs, the beam of the access link takes effect quickly when the beam is restored.

[0238] Optionally, the configuration information is used to indicate whether the NCR needs to reconfigure the beam indication information of the access link after the beam of the control link is restored, including:

[0239] The configuration information is used to indicate whether beam indication information of any access link needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored; or,

[0240] The configuration information is used to indicate at least one of the following: whether the type of beam indication information of the access link needs to be reconfigured after the beam of the control link is restored, the configuration method of the beam indication information of the access link, and the priority of the beam indication information of the access link.

[0241] Optionally, the configuration method includes one or more of the following: radio resource control RRC configuration, media access control control unit MAC-CE activation, and downlink control information DCI indication.

[0242] Indicating whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored in at least one of the following ways:

[0243] Method 6: Indicated by system default or by high-level parameter configuration

[0244] Through a predefined manner or configuration information of high-level parameters, the NCR is instructed whether the beam indication information of any access link needs to be reconfigured or does not need to be reconfigured after the beam of the control link is restored.

[0245] The specific implementation method can be found in the above-mentioned method 1, which will not be repeated here.

[0246] Method 7: Indicate by configuring the type of beam indication information

[0247] Through a predefined method or configuration information of high-level parameters, the NCR is instructed as to whether the type of beam indication information of the access link needs to be reconfigured after the beam of the control link is restored; the type of beam indication information of the access link is compared with the type of beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored to determine whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0248] The specific implementation method can be found in the above-mentioned method 2, which will not be repeated here.

[0249] Method 8: Instruction by configuring parameters

[0250] The configuration information of the predefined method or high-level parameters indicates to the NCR whether the configuration method of the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored; the configuration method of the beam indication information of the access link is compared with the configuration method of the beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored to determine whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0251] The specific implementation method can be found in the above-mentioned method 3, which will not be repeated here.

[0252] Method 9: Indicate by configuring the priority in the beam indication information

[0253] Indicates the priority of the beam indication information of the access link to the NCR whether it needs to reconfigure the beam after the beam of the control link is restored through a predefined method or configuration information of high-level parameters; compares the priority of the beam indication information of the access link with the priority of the beam indication information of the access link that needs to be reconfigured after the beam of the control link is restored, and determines whether the beam indication information of the access link needs to be reconfigured after the beam of the control link is restored.

[0254] In addition, the priority of the beam indicated in the non-periodic beam indication information can be configured by system default or through high-level parameters. For example, the beams indicated in the non-periodic beam indication information are all high priority or all low priority. For high-priority beams, no reconfiguration is required; for low-priority beams, reconfiguration is required.

[0255] The specific implementation method can be found in the above-mentioned method 4, which will not be repeated here.

[0256] Optionally, determining the configuration information by predefining or configuring high-level parameters may also include the following methods:

[0257] Method 10: Indicate by configuring the time interval from beam failure to beam recovery

[0258] Determining whether a time threshold of beam indication information of the access link needs to be reconfigured;

[0259] Determining a time interval from beam failure to beam recovery of the control link;

[0260] Based on the time threshold and the time interval, it is determined that if the time interval is less than or equal to the time threshold, the configuration information is used to indicate that after the beam of the control link is restored, it is not necessary to reconfigure the beam indication information of the access link; or, it is determined that if the time interval is greater than the time threshold, the configuration information is used to indicate that after the beam of the control link is restored, it is necessary to reconfigure the beam indication information of the access link.

[0261] Specifically, if the time interval is less than or equal to the time threshold, the configuration information is used to indicate that after the beam of the control link is restored, the beam indication information of the access link does not need to be reconfigured; or, if the time interval is greater than the time threshold, the configuration information is used to indicate that after the beam of the control link is restored, the beam indication information of the access link needs to be reconfigured; wherein, the time threshold is the time threshold for whether the beam indication information of the access link needs to be reconfigured, and the time interval is the time interval from the occurrence of beam failure to the beam recovery of the control link.

[0262] Whether the access link beam needs to be reconfigured is determined by checking whether the time interval from beam failure to beam recovery on the control link exceeds a threshold (herein, the time threshold). If the threshold is exceeded, the access link beam indication information indicates that reconfiguration is required. If the threshold is not exceeded, the access link beam indication information does not need to be reconfigured. The specific threshold value can also be configured by system default or through higher-layer parameters. For beam indications that do not require reconfiguration, the access link directly uses the beam indication information of the access link before the control link beam failure occurred.

[0263] It should be noted that the above-described methods 6 to 10 can be used in any combination to achieve configurable flexibility in determining whether the access link beam needs to be reconfigured when the control link beam is restored after a control link beam failure occurs. The above-described methods are used to distinguish access link beams, thereby indicating which beams require reconfiguration and which beams do not. This solves the problem in the prior art where, upon beam restoration, all access link beam indication information requires reconfiguration before it can take effect and data transmission can resume, resulting in long reconfiguration times and data transmission termination times. This allows the access link beam to quickly take effect when the control link beam is restored after a control link beam failure occurs.

[0264] Optionally, the method further includes:

[0265] If the beam indication information of the access link does not need to be reconfigured, retaining the beam indication information of the access link before the beam failure of the control link occurs; or,

[0266] If the beam indication information of the access link needs to be reconfigured, the beam indication information of the access link before the beam failure occurs in the control link is cleared.

[0267] Specifically, after a beam failure occurs in the control link, the beam indication information that is not reconfigured is retained, and the remaining beam indication information is cleared.

[0268] Optionally, the type of the beam indication information of the access link includes periodicity and semi-persistence, and the method further includes:

[0269] If the beam indication information of the access link is periodic beam indication information or semi-persistent beam indication information, and when it is determined that the periodic beam indication information or semi-persistent beam indication information of the access link does not need to be reconfigured, determine that the configuration information is used to indicate the effective time of the periodic beam indication information or semi-persistent beam indication information of the access link after the beam of the control link is restored;

[0270] The indication information is further used to instruct the physical layer to start forwarding data on the access link after the effectiveness time.

[0271] Among them, for periodic beam indication information and semi-persistent beam indication information, the system default or high-level parameter configuration information can be used to indicate the effective time of the periodic beam indication information or semi-persistent beam indication information of the access link before the control link beam is reused after the control link beam is recovered.

[0272] Specifically, the beam index corresponding to the beam of the access link that is configured with periodic or semi-continuous indication after the control link beam is recovered through a predefined method or high-level parameters can be reused, and the time slot (symbol) index at which the control link beam recovery is completed is used to indicate to the NCR the effective time of the periodic beam indication information or semi-continuous beam indication information of the access link after the control link beam is recovered, and to instruct the physical layer to start data forwarding on the access link in the time slot (symbol) where the beam index information exists after the effective time, to ensure that the beam of the access link can take effect quickly when the control link beam is recovered.

[0273] Optionally, the method for determining the effective time includes any one of the following:

[0274] Determining the validation time according to the first time slot after the time slot index after the beam of the control link is restored;

[0275] Determining the taking effect time according to the starting time slot of the first complete configuration period of the periodic beam indication information or the semi-persistent beam indication information of the access link after the time slot index after the beam of the control link is restored;

[0276] The effective time is determined based on a time slot index after the beam of the control link is restored that does not exceed a fixed time length.

[0277] Specifically, refer to the time slots determined in methods 10 to 30 to determine the effective time, and the specific real-time method will not be described in detail.

[0278] Optionally, the type of the beam indication information of the access link includes aperiodicity, and the method further includes:

[0279] If the beam indication information of the access link is non-periodic beam indication information, and when it is determined that the non-periodic beam indication information of the access link does not need to be reconfigured, determine whether the configuration information is used to indicate whether the non-periodic beam indication information of the access link is effective after the beam of the control link is restored.

[0280] Among them, for the non-periodic beam indication information, the system default or high-level parameter configuration information can be used to indicate to the NCR whether the non-periodic beam indication information of the access link before the control link beam is reused after the control link beam is recovered is effective.

[0281] Specifically, since the beam indication information of the access link before the control link beam occurs is non-periodic, the following scenario may exist: although the system is configured to reuse the beam indication information of the access link before the control link beam occurs, the non-periodic beam indication information may have expired before the beam of the control link is restored. Therefore, it is necessary to instruct the NCR to determine whether the beam indication information of the access link before the control link beam occurs that can be reused is invalid or valid, to ensure that the data on the access link can be forwarded normally after the beam of the control link is restored.

[0282] Optionally, determining whether the configuration information is used to indicate whether the aperiodic beam indication information of the access link is effective after the beam of the control link is restored includes:

[0283] If the time slot index of the time domain resource configured in the aperiodic beam indication information of the access link is less than or equal to the time slot index after the beam of the control link is restored, it is determined that the aperiodic beam indication information of the access link is no longer effective after the beam of the control link is restored, and the aperiodic beam indication information of the access link after the beam of the control link is restored is deleted; or

[0284] If the time slot index of the time domain resource configured in the non-periodic beam indication information of the access link is greater than the time slot index after the beam of the control link is recovered, it is determined that the non-periodic beam indication information of the access link takes effect after the beam of the control link is recovered, or it is used to indicate that the non-periodic beam indication information of the access link takes effect at a determined effective time after the beam of the control link is recovered.

[0285] Specifically, if the system is configured so that the beam index corresponding to the beam of the access link indicated non-periodically after the beam recovery of the control link can be reused: assuming that the time slot (symbol) index at which the beam recovery of the control link is completed is n, when the time slot (symbol) index of the time domain resource configuration in the beam indication information of the reused non-periodic indication (i.e., the beam indication information of the access link configured before the beam failure occurs) is less than or equal to n, the indication information is used to instruct the NCR that the beam indication information is no longer effective; if it is greater than n, the indication information is used to instruct the NCR that the beam indication information is effective.

[0286] The following describes the beam processing method in detail, taking the process of the base station notifying the NCR of the beam indication information of the access link after the beam of the control link is restored as an example:

[0287] Step a2: The base station instructs the NCR, through system default or configuration of high-level parameters, to reuse the beam information of the access link before the beam failure after the beam of the control link is restored. If this information is not configured, the beam information of all access links cannot be reused. If this information is configured, it should include but is not limited to one or more of the following:

[0288] Reusable beam indication type (multiple choices): periodic, semi-persistent, dynamic.

[0289] Reusable priorities: All, High Priority, Low Priority

[0290] Reusable configuration parameters (multiple selections possible): RRC parameters, MAC-CE parameters, DCI configuration

[0291] Step b2: After a control link beam failure occurs, the base station performs a control link beam recovery process.

[0292] Step c2: After the control link beam is restored, the base station configures the access link beams that need to be configured to the NCR through new beam indications, except for the beam information of the access link before the beam failure that can be reused, according to the configuration method in step a2.

[0293] Therefore, the present disclosure provides a beam processing method, which enables the access link beam to take effect quickly when the beam is restored after a beam failure occurs in the control link, thereby solving the problems of long access link beam reconfiguration time, long data transmission termination time, and poor user experience.

The NCR is communicatively connected to a base station and a terminal, respectively. The link between the NCR and the base station includes a control link, and the link between the NCR and the terminal includes an access link. The beam processing device 700 provided in this embodiment includes:
