Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a beam processing method, device and readable storage medium. Background Art

[0002] There are two links between the base station and the network-controlled repeater (Network-Control 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. NCR adds a control plane protocol stack on the basis of the original repeater. The base station can control some functions of 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 the Control link has a beam failure, 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 of the Access link. After the Control link beam is restored, the beam indication information of the Access link also needs to be reconfigured.

[0003] 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 of 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 termination time for data transmission.

[0004] Therefore, the prior art cannot achieve that when a beam failure occurs on a Control link, the beam of the Access link takes effect quickly when the beam of the Control link is restored. Summary of the invention

[0099] The term "and / or" in this application describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0100] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0101] In order to clearly understand the technical solution of the present application, 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. Figure 1 As shown, Figure 1 The figure shows the link relationship between the base station (e.g., gNB, i.e., 5G base station), NCR, and terminal (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 one link between the NCR and UE, which is the Access link. Figure 1 The Mobile termination in the NCR-MT (Mobile termination) shown refers to the mobile terminal; the Forwarding in the NCR-Fwd (Forwarding) refers to forwarding.

[0102] In the NCR topic of NR R18, the base station is supported to control the beams of the Control link, Backhaul link and Access link. When the Control link has a beam failure, 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 of the Access link. After the Control link beam is recovered, the beam information of the Access link also needs to be reconfigured.

[0103] The existing standard conclusions support three types of beam indication information for the Access link: periodic beam indication information (periodic beam indication, here refers to periodic beam indication information), semi-persistent beam indication information (semi-persistent beam indication, here refers to semi-persistent beam indication information) and aperiodic beam indication information (aperiodic beam indication, here refers to aperiodic beam indication information).

[0104] 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 termination time for data transmission.

[0105] Therefore, the prior art cannot achieve that when a beam failure occurs on a Control link, the beam of the Access link takes effect quickly when the beam of the Control link is restored.

[0106] The inventors further studied and found that, considering that the beam indication of the Access link has three types, namely periodic beam indication information, semi-persistent beam indication information and non-periodic beam indication information, different types of beam indications have different configuration times. The beam configuration of the Access link can be optimized. For example, in some cases, the configuration before the beam failure can be used, so that when the beam failure of the Control link occurs, the beam of the Access link can take effect quickly when the Control link beam is restored.

[0107] Therefore, based on the creative research of the above inventors, the beam processing method proposed in the present application is proposed. In the present application, the base station instructs the NCR whether the Access link beam needs to be reconfigured after the Control link beam is restored through the system default or high-level parameter configuration method, or the NCR determines whether the Access link beam needs to be reconfigured after the Control link beam is restored through the 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 Access link beam indication information after the Control link beam is restored is the Access link beam indication information sent on the Control link after the beam is restored. The problem in the prior art that when a beam failure occurs in the Control link, data transmission on the Access link is terminated, and 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 data transmission can be restored, resulting in a long reconfiguration time and a long termination time of data transmission is solved. The solution achieves that when a beam failure occurs in the Control link, the beam of the Access link takes effect quickly when the beam is restored.

[0108] Combination Figure 2 As shown, Figure 2 An interactive schematic diagram of the beam processing method provided in the embodiment of the present application, such as Figure 2As shown, in the embodiment of the present application, the base station determines the indication information by a predefined method or a method of configuring high-level parameters, and sends the indication information to the NCR. The indication information includes the configuration information of the predefined method or the high-level parameters; the NCR performs beam processing according to the (indication information) predefined method or the configuration information of the high-level parameters, that is, 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, then it is determined 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; if it is necessary to reconfigure the beam indication information of the Access link, then it is determined 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; wherein, the base station reconfigures the beam indication information of the Access link according to the existing process and sends it to the NCR.

[0109] Embodiments of the present application will be described below with reference to the accompanying drawings.

[0110] Figure 3 A schematic diagram of a flow chart of a beam processing method provided in an embodiment of the present application, such as Figure 3 As shown, the execution subject of the beam processing method provided in this embodiment is NCR, and the NCR is respectively connected to the base station and the terminal in communication, and the link between the NCR and the base station includes a control link Control link, and the link between the NCR and the terminal includes an access link Access link. The beam processing method provided in this embodiment of the application includes the following steps:

[0111] Step 301: When a beam failure occurs in the Control link, it is determined whether the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored, by a predefined method or by receiving configuration information including high-level parameters.

[0112] The configuration information of the predefined mode or high-layer parameters may be obtained from indication information received from a base station, or may be sent by other terminals, which is not specifically limited here.

[0113] 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 by system default or high-level parameter configuration.

[0114] 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.

[0115] Step 303: If the beam indication information of the Access link needs to be reconfigured, it is determined 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 and received after the beam is restored.

[0116] If reconfiguration is not required, the Access link directly uses the Access link beam before the Control link beam failure occurs. If reconfiguration is required, the Access link beam is reconfigured according to the existing process; for example: time domain resources and beam indication information and the status of addition, modification, and release 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 use parameters are indicated through DCI, that is, the beam indication information is indicated through DCI.

[0117] Therefore, the present application determines whether the Access link beam needs to be reconfigured after the Control link beam is restored by a predefined method or by receiving a method including high-level parameter configuration. If reconfiguration is not required, the Access link directly uses the beam indication information of the Access link before the Control link beam failure occurs; if reconfiguration is required, the beam indication information of the Access link is reconfigured according to the existing process. 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, any 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 termination time of data transmission. This solves the problem 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, any 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 termination time of data transmission. This 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.

[0118] 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 the high-layer parameters includes:

[0119] Determining, by a predefined method or by receiving configuration information including high-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,

[0120] Determine whether it is necessary to reconfigure the beam indication information of the Access link after the beam of the Control link is restored according to the predefined method or received configuration information containing high-level parameters; 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.

[0121] 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.

[0122] Determine whether the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored by at least one of the following methods:

[0123] Method 1: Determined by system default or through high-level parameter configuration

[0124] By a predefined manner or receiving configuration information including high-layer parameters, it is determined 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.

[0125] Specifically, if the configuration information does not configure one or more of the information formed by a combination of which type of beam indication information, which configuration mode of the beam indication information, and 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 by high-level parameters to indicate that after the beam of the Control link is restored, any beam indication information of the Access link needs to be reconfigured or does not need to be reconfigured, so the NCR can obtain the indication from the configuration information.

[0126] Method 2: Determine based on the type of beam indication information

[0127] Determine, by a predefined method or by receiving configuration information including 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 the beam indication information of the Access link with the type 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.

[0128] 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. Specifically, which types of beam indication information need to be reconfigured can also be configured by system default or by high-level parameters. For beam indication information that does not need to be reconfigured, the Accesslink directly uses the beam indication information of the Access link before the beam failure of the Control link occurs.

[0129] Method 3: Determine based on the method used to configure parameters

[0130] Determine, by a predefined method or by receiving configuration information including high-level parameters, whether a 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, to determine whether the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored.

[0131] Specifically, it is determined whether the Access link beam needs to be reconfigured after the Control link beam is restored according to the configuration parameters of the Access link beam indication. For example, the parameter information configured by RRC does not need to be reconfigured; the information configured by MAC-CE and DCI needs to be reconfigured. Among them, which specific configuration parameters need to be reconfigured can also be configured by system default or by high-level parameters. For the 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.

[0132] Method 4: Determine based on the priority in the beam indication information

[0133] Determine, by a predefined method or by receiving configuration information including high-level parameters, whether the priority of the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored; and determine, by comparing 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, whether the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored.

[0134] Specifically, whether the Access link beam needs to be reconfigured after the Control link beam is restored is determined according to 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 Access link beam indication information before the Control link beam failure occurs.

[0135] 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, reconfiguration is not required; for low-priority beams, reconfiguration is required.

[0136] Optionally, whether the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored is determined by a predefined method or by receiving configuration information including high-level parameters. The determination may also be made by:

[0137] Method 5: Determine based on the time interval from beam failure to beam recovery

[0138] Determine whether it is necessary to reconfigure the time threshold of the beam indication information of the Access link by a predefined manner or by receiving configuration information including high-level parameters;

[0139] Determine the time interval from beam failure to beam recovery of the Control link;

[0140] If the time interval is less than or equal to the 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 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.

[0141] Specifically, whether the Access link beam needs to be reconfigured is determined based on whether the time interval from the occurrence of beam failure to beam recovery of the Control link exceeds a threshold value (herein, the time threshold). If it exceeds the threshold value, the beam indication information of the Access link needs to be reconfigured; if it does not exceed the threshold value, the beam indication information of the Access link does not need to be reconfigured. The specific threshold value can also be configured by system default or by high-level parameters. For beam indications that do 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.

[0142] It should be noted that the above-mentioned methods 1 to 5 can be used in any combination to achieve the configurable flexibility of whether the beam of the Access link needs to be reconfigured when the Control link beam is restored after a beam failure occurs on the Control link. The beams of the Access link are distinguished by the above-mentioned method to determine what kind of beams need to be reconfigured and what kind of beams do not need to be configured. Therefore, the problem in the prior art that when the beam is restored, any beam indication information of 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 termination time of data transmission is solved, and then the beam of the Access link can be quickly effective when the Control link beam is restored after a beam failure occurs on the Control link.

[0143] In the embodiment of the present application, the NCR 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 by system default (here, configuration by a predefined method) or reading a high-level parameter configuration, or the NCR determines 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 by system default (here, configuration by a predefined method) or reading a high-level parameter configuration, and then 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. The problem in the prior art that the data transmission of the Access link is terminated after the beam failure of the Control link occurs, and when the beam is restored, any 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 is solved, and the beam of the Access link is quickly effective when the beam is restored after the beam failure of the Control link occurs is realized.

[0144] Optionally, the method further comprises:

[0145] If the beam indication information of the Access link does not need to be reconfigured, the beam indication information of the Access link before the beam failure of the Control link occurs is retained;

[0146] 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.

[0147] 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. 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.

[0148] Optionally, the type of the beam indication information of the Access link includes periodicity and semi-persistence, and the method further includes:

[0149] 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 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;

[0150] Instruct the physical layer to start forwarding the data on the Access link after the validation time.

[0151] 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 Control link beam is reused after the Control link beam is recovered can be determined through the system default or high-level parameter configuration information.

[0152] Specifically, if the system is configured that the beam index corresponding to the Access link beam that is periodically or semi-continuously indicated after the Control link beam is recovered can be reused, the time when the periodic beam indication information or semi-continuous beam indication information of the Access link after the Control link beam is recovered is determined by the time slot (symbol) index at which the Control link beam recovery is completed, 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 Access link beam can take effect quickly when the Control link beam is recovered.

[0153] 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:

[0154] Determine the effectiveness time according to the first time slot after the time slot index after the beam of the Control link is restored;

[0155] Determine the effective 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 recovery of the Control link;

[0156] The effective time is determined according to a time slot index after the beam of the Control link is restored and the time slot index does not exceed a fixed time length.

[0157] Specifically, the time slot determined by the following method is used to determine the effective time (see Figure 4 shown):

[0158] 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 time or specified time in the first time slot.

[0159] Mode 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.

[0160] Mode 30: The beam recovery of the Control link is completed no later than a fixed time length, 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 length.

[0161] 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 beam of the Control link is restored, while achieving the flexibility of configurable effectiveness time.

[0162] Optionally, the type of the beam indication information of the Access link includes aperiodicity, and the method further includes:

[0163] If the beam indication information of the Access link is aperiodic beam indication information, and when it is determined that the aperiodic beam indication information of the Access link does not need to be reconfigured, it is determined whether the aperiodic beam indication information of the Access link is effective after the beam of the Control link is restored.

[0164] Among them, for the non-periodic beam indication information, 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 determined by the system default or high-level parameter configuration information.

[0165] 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 become invalid before the Control link beam is restored. Therefore, it is necessary to determine whether the reusable beam indication information of the Access link before the Control link beam occurs is invalid or valid to ensure that the data on the Access link can be forwarded normally after the Control link beam is restored.

[0166] Optionally, determining whether the aperiodic beam indication information of the Access link is effective after the beam of the Control link is restored includes:

[0167] 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 is deleted after the beam of the Control link is restored; or,

[0168] 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 restored, it is determined that the non-periodic beam indication information of the Access link takes effect after the beam of the Control link is restored, or it is determined 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 restored.

[0169] Specifically, if the system is configured 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.

[0170] The following takes the process of determining the beam indication information of the Access link after the beam of the Control link is restored by the NCR as an example to explain the beam processing method in detail:

[0171] 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 through system default or reading high-level parameter configuration. The beam indication information should include but is not limited to one or more of the following combinations:

[0172] Types of beam indication information that can be reused (multiple choices): periodic, semi-persistent, dynamic (eg, non-periodic).

[0173] Reusable priorities: All, High Priority, Low Priority.

[0174] Reusable configuration parameters (multiple selections are allowed): RRC parameters, MAC-CE parameters, DCI configuration.

[0175] It should be noted that: if the above information is not configured, the beam information of all Access links cannot be used for 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 for the forwarding link after the C-link beam is restored.

[0176] Step b1: After a beam failure occurs on 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.

[0177] Step c1: After the beam of the Control link is restored, the NCR, according to the method obtained in step a1, makes the beam indication information of the Access link before the failure of the reusable beam effective at the specified effective time (here, the effective start time). After the effective time, the Access link starts data forwarding in the time slot (symbol) where the beam index information exists (for example, the time slot where the effective time is located or the time slot where the time is located later).

[0178] For periodic or semi-persistent beam indication information, the method for specifying the effective time can be:

[0179] The first time slot (symbol) after the time slot (symbol) in which C-link beam recovery is completed.

[0180] After the time slot (symbol) in which the C-link beam recovery is completed, the Access link beam indication information determines the starting time slot (symbol) of the first complete configuration cycle.

[0181] The C-link beam recovery is completed no later than a fixed time, such as 1 ms, after the time slot (symbol).

[0182] For non-periodic beam indication information, the method for determining whether it is effective is:

[0183] When the time slot (symbol) index of the time domain resource configuration in the reusable non-periodic beam indication information (i.e., the beam indication information of the Accesslink 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.

[0184] Exemplarily, in Embodiment 1, the beam processing method is described in detail below by taking one or a combination of methods 2 to 4 as an example.

[0185] Step 1: The configuration information configured by the system default or high-level parameter configuration method determines one or more of the types of Access link beam indication information that do not need to be reconfigured after the Control link beam is restored, the method of configuring parameters, and the priority; for example: for 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, but the MAC-CE activation information needs to be re-indicated.

[0186] Step 2: After a beam failure occurs on the Control link, the beam indication information that is not to be reconfigured is retained, and the remaining beam indication information is cleared;

[0187] 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.

[0188] 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.

[0189] Exemplarily, in Embodiment 2, the beam processing method is described in detail below by taking Mode 1 and one or a combination of multiple modes 2 to 4 as an example.

[0190] 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;

[0191] 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 Control link beam is restored through system default or high-level parameter configuration. For example, for 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, but the MAC-CE activation information needs to be re-indicated.

[0192] Step 3: After a Control link beam failure occurs, the beam indication information that is not to be reconfigured is retained, and the remaining beam indication information is cleared.

[0193] 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.

[0194] 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.

[0195] For example, in Embodiment 3, the beam processing method is described in detail below by taking Mode 5 and one or more combinations of Modes 2 to 4 as an example.

[0196] Step 1: Determine one or more of the types, configuration parameters, and priorities of the beam indication information of the Access link 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: for 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, but the MAC-CE activation information needs to be re-indicated.

[0197] Step 2: Determine the time interval threshold from beam failure to beam recovery that does not require reconfiguration after the beam recovery of the Control link through system default or high-level parameter configuration.

[0198] Step 3: After a Control link beam failure occurs, the beam indication information that is not to be reconfigured is retained, and the remaining beam indication information is cleared.

[0199] Step 4: After the beam of the Control link is restored, if the time interval from beam failure to beam restoration does not exceed the threshold value, the retained beam indication information that is not reconfigured will take effect at the effective time specified by the system. If the time interval from beam failure to beam restoration exceeds the threshold value, the retained beam indication information that is not reconfigured will be cleared.

[0200] Step 5: After the Control link beam is restored, the Access link beam index that needs to be reconfigured is reconfigured by the base station by sending beam indication information to the NCR.

[0201] For example, in Embodiment 4, the beam processing method is described in detail below by taking the combination of Mode 1 and Mode 5 as an example.

[0202] Step 1: Determine whether the Access link beam needs to be reconfigured after the Control link beam is restored according to method 1;

[0203] Step 2: If reconfiguration is required, execute Step 4; if reconfiguration is not required, execute Step 3.

[0204] Step 3: Determine the time interval threshold from beam failure to beam recovery that does not require reconfiguration after the Control link beam is recovered through system default or high-level parameter configuration. After a C-link beam failure occurs, the beam indication information is retained. After the C-link beam is recovered, if the time interval from beam failure to beam recovery does not exceed the threshold, the retained beam indication information that is not reconfigured will take effect at the effective time specified by the system. If the time interval from beam failure to beam recovery exceeds the threshold, the retained beam indication information that is not reconfigured will be cleared.

[0205] Step 4: After the Control link beam is restored, the Access link beam index that needs to be reconfigured is reconfigured by the base station by sending beam indication information to the NCR.

[0206] For example, in Embodiment 5, the beam processing method is described in detail below by taking Mode 1 and Mode 5 and a combination of one or more of Modes 2 to 4 as an example.

[0207] Step 1: Determine whether the Access link beam needs to be reconfigured after the Control link beam is restored according to method 1;

[0208] Step 2: If reconfiguration is required, execute Step 6; if reconfiguration is not required, 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 does not need to be reconfigured for its RRC parameters, but the MAC-CE activation information needs to be re-indicated.

[0209] 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.

[0210] Step 4: After a Control link beam failure occurs, the beam indication information that is not to be reconfigured is retained, and the remaining beam indication information is cleared.

[0211] Step 5: After the beam of the Control link is restored, if the time interval from beam failure to beam restoration does not exceed the threshold value, the retained beam indication information that is not reconfigured will take effect at the effective time specified by the system. If the time interval from beam failure to beam restoration exceeds the threshold value, the retained beam indication information that is not reconfigured will be cleared.

[0212] Step 6: After the control link beam is restored, the base station re-sends the beam indication information to the NCR to configure the access link beam index that needs to be reconfigured.

[0213] 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.

[0214] In actual applications, the 38.321 standard describes how to handle the Access link beam after a control link beam failure:

[0215] 1> If the UE type is NCR;

[0216] 2> Stop all time slot forwarding of NCR AC-link

[0217] 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

[0218] Note: If retained, the beam indication information can continue to be used after the beam is restored.

[0219] 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

[0220] Note: If retained, the beam indication information can continue to be used after the beam is restored.

[0221] 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

[0222] Note: If retained, the beam indication information can continue to be used after the beam is restored.

[0223] In addition, the processing methods include:

[0224] 3> If there is any beam configuration information (all configurations not released when the beam is restored)

[0225] 4> Instruct the physical layer to start AC-link forwarding, and the forwarding start time is XXX (the three methods from method 10 to method 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).

[0226] The 38.213 standard describes how to handle the Access link beam after a Control link beam failure:

[0227] 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 sending or receiving 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 beam configuration that can reuse the NCR's access link before the link failure occurs. If the upper layer configures the beam configuration that can reuse the NCR's access link before the link failure occurs:

[0228] For periodic and semi-continuous beam configurations, the effective time of the beam configuration is XXX (the three methods from method 10 to method 30 mentioned above: the first time slot (symbol) after the beam failure recovery is completed; the first period start time slot (symbol) after the beam failure recovery is completed; no later than 1ms after the beam failure recovery is completed).

[0229] 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.

[0230] Therefore, the present application provides a beam processing method, which enables the Access link beam to take effect quickly when the beam fails in the Control link and is restored, thereby solving the problems of long Access link beam reconfiguration time, long data transmission termination time, and poor user experience.

[0231] Figure 5 A schematic diagram of a flow chart of a beam processing method provided in another embodiment of the present application is shown in FIG. Figure 5 As shown, the execution subject of the beam processing method provided in this embodiment is a base station, the base station is connected to the network-controlled repeater NCR, the NCR is connected to the terminal, and the link between the NCR and the base station includes a control link Control link, and the link between the NCR and the terminal includes an access link Access link. The beam processing method provided in this embodiment of the application includes the following steps:

[0232] Step 501: Send configuration information to the NCR, where the configuration information is predefined configuration information or high-level parameters; 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;

[0233] If the configuration information is used to indicate that the beam indication information of the Access link does not need to be reconfigured, 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

[0234] 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 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.

[0235] In the embodiment of the present application, the base station performs parameter configuration by a predefined method or by configuring high-level parameters, and indicates to the NCR whether the configuration information of the beam indication information of the Access link needs to be reconfigured 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 adding, modifying, and releasing through RRC parameters; configuring the time domain resources and the beam indication candidate set through RRC parameters, and configuring the activation status through MAC-CE; configuring the time domain resources and the beam indication candidate set through RRC parameters, and indicating the currently used parameters through DCI, that is, indicating the beam indication information through DCI.

[0236] Therefore, the present application instructs the NCR whether the Access link beam needs to be reconfigured after the Control link beam 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 Control link beam failure occurs; if reconfiguration is required, the beam indication information of the Access link is reconfigured according to the existing process. The problem in the prior art that when a Control link beam failure occurs, the data transmission of the Access link is terminated, and when the beam is restored, any 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 termination time of data transmission. This solves the problem that when a Control link beam failure occurs, the Access link beam takes effect quickly when the beam is restored.

[0237] 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:

[0238] The configuration information is used to indicate that after the beam of the Control link is restored, any beam indication information of the Access link needs to be reconfigured or does not need to be reconfigured; or,

[0239] 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.

[0240] 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.

[0241] 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:

[0242] Method 6: Indicated by system default or by high-level parameter configuration

[0243] Through a predefined manner or configuration information of a high-level parameter, 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.

[0244] Among them, the specific implementation method can refer to the above-mentioned method 1, which will not be repeated here.

[0245] Method 7: Indicate by configuring the type of beam indication information

[0246] Indicate to the NCR whether the type of beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored, through a predefined method or configuration information of high-level parameters; compare the type of the 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, to determine whether the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored.

[0247] Among them, the specific implementation method can refer to the above-mentioned method 2, which will not be repeated here.

[0248] Method 8: Instruction by configuring parameters

[0249] Indicate, through a predefined method or high-level parameter configuration information, whether the NCR needs to reconfigure the configuration method of the beam indication information of the Access link 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 Accesslink that needs to be reconfigured after the beam of the Control link is restored, to determine whether the beam indication information of the Accesslink needs to be reconfigured after the beam of the Control link is restored.

[0250] Among them, the specific implementation method can refer to the above-mentioned method 3, which will not be repeated here.

[0251] Method 9: Indicate by configuring the priority in the beam indication information

[0252] Indicate to the NCR whether the priority of the beam indication information of the Access link needs to be reconfigured after the beam of the Control link is restored, through a predefined method or configuration information of 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 Accesslink that needs to be reconfigured after the beam of the Control link is restored, to determine whether the beam indication information of the Accesslink needs to be reconfigured after the beam of the Control link is restored.

[0253] 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, reconfiguration is not required; for low-priority beams, reconfiguration is required.

[0254] Among them, the specific implementation method can refer to the above-mentioned method 4, which will not be repeated here.

[0255] Optionally, the determining of the configuration information by a predefined manner or by configuring high-level parameters may also include the following manners:

[0256] Method 10: Indicate by configuring the time interval from beam failure to beam recovery

[0257] Determine whether it is necessary to reconfigure the time threshold of the beam indication information of the Access link;

[0258] Determine the time interval from beam failure to beam recovery of the Control link;

[0259] According to the time threshold and the time interval, it is determined that if the time interval is less than or equal to the 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 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.

[0260] Specifically, whether the time interval from the occurrence of beam failure to beam recovery of the Control link exceeds a threshold value (herein, the time threshold) is configured to indicate whether the Access link beam needs to be reconfigured. If it exceeds the threshold value, it indicates that the beam indication information of the Access link needs to be reconfigured; if it does not exceed the threshold value, it indicates that the beam indication information of the Access link does not need to be reconfigured. The specific threshold value can also be configured by system default or by high-level parameters. For beam indications that do 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.

[0261] It should be noted that the above-mentioned methods 6 to 10 can be used in any combination to achieve the configurable flexibility of whether the beam of the Access link needs to be reconfigured when the Control link beam is restored after a beam failure occurs on the Control link. The beams of the Access link are distinguished by the above-mentioned method, and then it is indicated what kind of beams need to be reconfigured and what kind of beams do not need to be configured. Therefore, the problem in the prior art that when the beam is restored, any beam indication information of 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 termination time of data transmission is solved, and then it can be achieved that when the beam failure occurs on the Control link, the beam of the Access link can be quickly effective when the Controllink beam is restored.

[0262] Optionally, the method further comprises:

[0263] 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,

[0264] 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.

[0265] Specifically, after a beam failure occurs in the Control link, the beam indication information that is not to be reconfigured is retained, and the remaining beam indication information is cleared.

[0266] Optionally, the type of the beam indication information of the Access link includes periodicity and semi-persistence, and the method further includes:

[0267] 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;

[0268] The indication information is also used to instruct the physical layer to start forwarding the data on the Accesslink after the effectiveness time.

[0269] 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.

[0270] 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 Access link beam can take effect quickly when the Control link beam is recovered.

[0271] Optionally, the method for determining the effective time includes any of the following:

[0272] Determine the effectiveness time according to the first time slot after the time slot index after the beam of the Control link is restored;

[0273] Determine the effective 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 recovery of the Control link;

[0274] The effective time is determined according to a time slot index after the beam of the Control link is restored and the time slot index does not exceed a fixed time length.

[0275] 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 repeated.

[0276] Optionally, the type of the beam indication information of the Access link includes aperiodicity, and the method further includes:

[0277] 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.

[0278] Among them, for the non-periodic beam indication information, the system default or high-level parameter configuration information can be used to instruct the NCR whether to reuse the non-periodic beam indication information of the Access link before the Control link beam is restored after the Control link beam is restored.

[0279] 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.

[0280] Optionally, determining that 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:

[0281] 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 is deleted after the beam of the Control link is restored; or,

[0282] 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 restored, it is determined that the non-periodic beam indication information of the Access link takes effect after the beam of the Control link is restored, 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 restored.

[0283] Specifically, if the system is configured that the beam index corresponding to the beam of the Accesslink 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 reusable non-periodic indication beam indication information (i.e., the beam indication information of the Accesslink 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.

[0284] The following takes 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 to explain the beam processing method in detail:

[0285] 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 not be limited to one or more of the following combinations:

[0286] Reusable beam indication types (multiple choices): periodic, semi-persistent, dynamic.

[0287] Reusable priorities: All, High Priority, Low Priority

[0288] Reusable configuration parameters (multiple selections possible): RRC parameters, MAC-CE parameters, DCI configuration

[0289] Step b2: After a Control link beam failure occurs, the base station performs a Control link beam recovery process.

[0290] Step c2: After the beam of the Control link 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.

[0291] Therefore, the present application provides a beam processing method, which enables the Access link beam to take effect quickly when the beam fails in the Control link and is restored, thereby solving the problems of long Access link beam reconfiguration time, long data transmission termination time, and poor user experience.
