Description

[Technical Field]

[0001] The present invention relates to the field of communications technology, and more particularly to a method, an apparatus, and a communications system for transmitting and receiving setting information. [Background technology]

[0002] Radio Link Monitoring (RLM) is used to monitor the downlink radio link quality of a specific cell, which may include, for example, a primary cell (PCell) or a secondary cell (SCell). In-sync and out-of-sync indications are the results of the physical layer radio link monitoring.

[0003] For example, if the radio link quality on all configured RLM resources of one particular cell exceeds a threshold Q out When the radio link quality on any one configured RLM resource of one particular cell is worse than the threshold Q, the physical layer of the terminal device reports an out-of-sync indication to a higher layer (e.g., radio resource control RRC layer) within the frame in which the radio link quality assessment is performed. in When the synchronization is better than the predetermined value, the physical layer of the terminal device reports a synchronization indication to the upper layer within the frame in which the radio link quality is evaluated.

[0017] The foregoing and other features of the present invention will become apparent from a consideration of the accompanying drawings and the following description. While the specification and drawings disclose particular embodiments of the present invention, they represent only some of the embodiments which may employ the principles of the present invention. It is to be understood that the present invention is not limited to the described embodiments, but rather includes all modifications, variations, and alternatives which fall within the scope of the appended claims.

[0018] In embodiments of the present invention, the term "communication network" or "wireless communication network" may refer to a network conforming to any communication standard, such as LTE (Long Term Evolution), LTE-A (LTE-Advanced), WCDMA (Wideband Code Division Multiple Access), HSPA (High-Speed ​​Packet Access), etc.

[0019] Additionally, communication between devices in a communication system may occur according to any stage of communication protocol, including, but not limited to, 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G and future 5G, New Radio (NR), and / or other conventional or future developed communication protocols.

[0020] In the embodiments of the present invention, the term "network device" refers to a device in a communication system that connects a terminal device to a communication network and provides services to the terminal device, for example, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobile management entity (MME), a network gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0021] The base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), and a 5G base station (gNB), and may further include a Remote Radio Head (RRH), a Remote Radio Unit (RRU), a relay, or a low-power node (e.g., femto, pico, etc.). The term "base station" may include some or all of the functions thereof, and each base station can provide communication coverage for a specific geographical area. The term "cell" may refer to a base station and / or the area it covers, depending on the context of the term.

[0022] In embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives services from the network, for example, via a network device. A user equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a user station (SS), an access terminal (AT), a station, etc.

[0023] The user device may include, but is not limited to, a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a machine-type communication device, a laptop computer, a cordless phone, a smartphone, a smart watch, a digital camera, etc.

[0024] Furthermore, for example, in scenarios such as the Internet of Things (IoT), the user equipment may also be a monitoring or measuring device or apparatus, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

[0025] The following describes an example scenario of an embodiment of the present invention, but the present invention is not limited to this.

[0026] 1 is a diagram illustrating a communication system according to an embodiment of the present invention, taking a terminal device and a network device as an example. As shown in FIG. 1, a communication system 100 may include a network device 101 and a terminal device 102. For convenience, FIG. 1 illustrates an example in which only one terminal device and only one network device are included, but the embodiment of the present invention is not limited thereto.

[0027] In an embodiment of the present invention, conventional traffic or future traffic may be transmitted between the network device 101 and the terminal device 102. Such traffic may include, but is not limited to, enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC), Ultra-Reliable and Low-Latency Communication (URLLC), etc.

[0028] In a New Radio (NR) system, for example, the following trigger conditions for radio link failure are supported: timer expiration (where the timer is started upon determining that a radio problem exists); random access procedure failure; and radio link control (RLC) failure.

[0029] 2 is a diagram illustrating the steps of detecting, determining, and recovering from a wireless problem in an embodiment of the present invention. As shown in FIG. 2, when the terminal device performs wireless link monitoring, it may be in different stages. For example, it may be in the first stage (T1) of normal operation, or it may be in the following stages:

[0030] When the Radio Resource Control (RRC) layer of the terminal device receives a predetermined number (e.g., N310 consecutive) of Out of Sync (OOS) indications for a specific cell from a lower layer (e.g., physical layer) indication, it starts a timer (e.g., T310). This phase may be referred to as a second phase (T2) of radio problem detection.

[0031] If the RRC layer receives a predetermined number (e.g., N311 consecutive) of In Sync (IS) indications for this particular cell while the timer is running, it stops the timer. When the timer times out, the RRC layer determines that a radio link failure has occurred. This phase may be referred to as the third phase (T3) of radio problem recovery.

[0032] 2 is used as an example to describe the radio problem recovery procedure, but the embodiment of the present invention is not limited thereto. For example, the first stage (T1) of normal operation may include a period during which the RRC layer of the terminal device does not receive any out-of-sync indication from a lower layer (e.g., a physical layer) and a timer for radio problem recovery is not started; or a period during which the RRC layer of the terminal device does not receive consecutive out-of-sync indications from a lower layer and a timer for radio problem recovery is not started. The period may include a predefined period, a period configured by the network device, or a period from when the terminal device enters a connected state until it receives reconfiguration information.

[0033] In addition, in an NR system, a network device may provide parameters related to radio link monitoring / radio problem detection for a terminal device, such as:

[0034] RLM IS / OOS threshold setting: NR RLM supports two sets of IS / OOS parameters, and the network device can use index 0 or 1 to instruct the terminal device to use one of them. For example, 0 is the default value, which corresponds to an IS threshold of 2% Block Error Rate (BLER) and an OOS threshold of 10% BLER. The threshold setting may be a UE-specific parameter.

[0035] Resource configuration for RLM: For example, a monitoring frequency of 3 GHz or less supports a configuration of two resources; a monitoring frequency of 3-6 GHz supports a configuration of four resources; and a monitoring frequency of 6 GHz or more supports a configuration of eight resources. These resources may indicate a synchronization signal block (SSB) for RLM by an SSB index, or a channel state information reference signal (CSI-RS) resource by an identifier (ID) of the CSI-RS resource. The resource configuration may be a UE-specific parameter.

[0036] For example, only SSB may be configured, or only CSI-RS resources may be configured, or SSB and CSI-RS resources may be configured simultaneously. Note that the present invention is not limited to this, and for example, resources of other reference signals for measuring channel conditions may also be configured.

[0037] Due to the introduction of beams and to support different traffic with different radio link qualities, flexible radio link monitoring configuration needs to be supported. In an NR system, when a higher layer (e.g., the RRC layer) configures / reconfigures the above-mentioned resources or parameters, it needs to consider the impact on RLM, physical layer problem detection, and radio link failure triggers. For example, when radio link monitoring is reconfigured and a change occurs in the resources for RLM, this means that the target of radio link monitoring changes. Also, when radio link monitoring is reconfigured and an IS / OOS threshold changes, this means that the result of radio link monitoring may change.

[0038] Therefore, it is desirable not only to be able to support different applications with different beam deployments and different radio link qualities, but also to improve the flexibility and accuracy of the settings for radio link monitoring.

[0039] Hereinafter, an embodiment of the present invention will be described using an NR system and PDSCH as an example, but the present invention is not limited thereto and can be applied to any system or scenario in which a similar problem exists. [Example]

[0040] In an embodiment of the present invention, a method for receiving setting information is provided. Figure 3 is a diagram showing the method for receiving setting information in an embodiment of the present invention. As shown in Figure 3, the method 300 for receiving setting information includes the following steps:

[0041] Step 301: A terminal device receives first setting information for radio link monitoring sent by a network device, the first setting information including at least a threshold setting for the radio link monitoring and / or a resource setting for the radio link monitoring.

[0042] In this embodiment, the radio link monitoring threshold configuration includes the following: criteria and / or parameters for selecting a radio link monitoring threshold from among multiple thresholds, and / or an index for indicating an in-sync threshold and / or an out-of-sync threshold. The resource configuration for radio link monitoring includes an index for indicating an SSB and / or an identifier (ID) for obtaining a CSI-RS resource. However, the present invention is not limited thereto, and other parameters may be used, for example.

[0043] For example, a pair of thresholds from a plurality of threshold pairs may be selected as the radio link monitoring thresholds based on criteria and / or parameters, and the criteria and / or parameters may include at least one of the following: the criteria themselves, parameters for determining the criteria, parameters calculated based on the criteria, indexes of the criteria, etc. However, the present invention is not limited thereto.

[0044] In this embodiment, the first configuration information may be carried in an information element (IE) of a reconfiguration message (e.g., an RRC reconfiguration message), and the first configuration information may further be carried in one or more messages or one or more IEs.

[0045] For example, IE 1 in message 1 and IE 2 in message 2 can both carry the first configuration information, and IE 2 in message 2 can modify or replace IE 1 in message 1. Note that message 1 and message 2 may be different messages with different names and used in different scenarios, or may be the same message. The present invention is not limited to these specific implementation methods.

[0046] This allows the network device to send threshold settings and / or resource settings for radio link monitoring to the terminal device, which not only allows for the introduction of beams and supports different traffic with different radio link qualities, but also improves the flexibility and accuracy of settings for radio link monitoring.

[0047] 4 is a diagram illustrating a method for transmitting and receiving setting information according to an embodiment of the present invention. As shown in FIG. 4, the method for transmitting and receiving setting information 400 includes the following steps:

[0048] Step 401: A network device sends first configuration information for radio link monitoring to a terminal device, the first configuration information including at least a threshold setting for the radio link monitoring and / or a resource setting for the radio link monitoring; and Step 402: The network device sends second setting information for wireless link monitoring to the terminal device, where the second setting information is used to at least change or delete the setting of the first setting information.

[0049] In this embodiment, the first setting information and the second setting information may each be carried in an information element (IE) of a reconfiguration message (e.g., an RRC reconfiguration message), and the first setting information or the second setting information may further be carried in one or more messages, or may be carried in one or more IEs.

[0050] For example, IE 1 in message 1 may carry first configuration information, IE 2 in message 2 may carry second configuration information, or IE 2 in message 2 may modify or replace IE 1 in message 1. Note that message 1 and message 2 may be different messages with different names and used in different scenarios, or may be the same message. The present invention is not limited to these specific implementation methods.

[0051] In one implementation, the terminal device can determine that the second configuration information is different from the first configuration information, which may include at least one of the following cases: resources in the second configuration information are different from resources in the current configuration information, thresholds in the second configuration information are different from thresholds in the current configuration information, all resources in the second configuration information are different from resources in the current configuration information, some resources in the second configuration information are different from resources in the current configuration information, the thresholds in the second configuration information are greater than the thresholds in the current configuration information, and the thresholds in the second configuration information are smaller than the thresholds in the current configuration information.

[0052] For example, the second setting information may be used to change the first setting information, or the second setting information may be used to remove a setting related to the first setting information. For example, the second setting information may reset the index of an IS / OOS threshold setting from 0 to 1, or the second setting information may reset the index of an IS / OOS threshold setting that was not previously set (e.g., a default threshold pair) to 1. Also, for example, the second setting information may reset the index of an IS / OOS threshold setting from 1 to 0, or the second setting information may not include an IS / OOS threshold setting when the need code of the threshold setting is need R or need N.

[0053] In one embodiment, after receiving the second setting information, the terminal device can apply the second setting information to radio link monitoring, and the terminal device can include at least one of the following operations: re-counting consecutive out-of-sync indications; resetting a consecutive out-of-sync indication counter; re-counting consecutive in-sync indications; resetting a consecutive in-sync indication counter; and restarting a first timer.

[0054] The first timer may be related to at least the number of consecutive out-of-sync indications, or may be related to at least the number of consecutive in-sync indications. For example, the first timer may be T310, and the timer may be started or stopped based on the number of consecutive out-of-sync indications or the number of consecutive in-sync indications. However, this does not exclude starting or stopping the timer using other mechanisms. In other words, the present invention is not limited thereto, and may be, for example, another timer or other time measurement method.

[0055] The reconfiguration of this embodiment will be further explained below by taking the steps shown in FIG. 2 as an example.

[0056] 5 is another diagram illustrating a method for transmitting and receiving setting information according to an embodiment of the present invention. As shown in FIG. 5, the method for transmitting and receiving setting information 500 includes the following steps:

[0057] Step 501: A network device sends first setting information for radio link monitoring to a terminal device, where the first setting information includes at least a threshold setting for the radio link monitoring and / or a resource setting for the radio link monitoring.

[0058] Step 502: The network device sends second setting information for wireless link monitoring to the terminal device, where the second setting information is used to at least change or delete the setting of the first setting information.

[0059] As shown in FIG. 5, the method may further include the following steps:

[0060] Step 503: The terminal device applies the second setting information to wireless link monitoring; and Step 504: The terminal device resets the parameters related to radio link monitoring.

[0061] For example, after the terminal device receives the second setting information, the RLM operation may return, for example, to the first stage of normal operation, or to the initial state or other intermediate state in which the terminal device is located when receiving the second setting information.

[0062] Also, for example, if the terminal device determines that it is in the second stage of wireless problem detection after receiving the second setting information, it can recalculate the number of consecutive out-of-sync indications.

[0063] Also, for example, if the terminal device determines that it is in the third stage of wireless problem recovery after receiving the second setting information, for example, while the timer for wireless problem recovery (e.g., T310) is running, the terminal device may perform one of the following operations: recalculate the number of consecutive synchronization indications; restart the timer for recovery (e.g., T310) and recalculate the number of consecutive synchronization indications; restart the timer for recovery (e.g., T310) and continue to calculate the number of consecutive synchronization indications; stop the timer for recovery (e.g., T310) and recalculate the number of consecutive out-of-sync indications.

[0064] This not only supports the introduction of beams and different traffic with different radio link qualities, but also improves the flexibility and accuracy of the configuration for radio link monitoring. In addition, reconfiguration parameters can be applied to radio link monitoring in a timely manner, and RLM-related variables can be reset, which solves the problem of inaccurate evaluation of radio link quality in the RRC layer due to the application of new configurations.

[0065] In another implementation method, it can be determined whether to apply the modified or deleted settings to radio link monitoring based on the second setting information based on one or more cases of an out-of-sync indication, a synchronization indication, and a timer.

[0066] 6 is a diagram illustrating an example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 6, before receiving the second configuration information, the terminal device can determine that there is at least one out-of-sync indication and the second timer is not started. For example, the RRC layer can determine whether there is at least one out-of-sync indication, or how many out-of-sync indications there are, or how many consecutive out-of-sync indications there are, based on the indication of the physical layer. For specific details, please refer to the prior art.

[0067] In this case, after receiving the second setting information, the terminal device can determine and start a second timer (e.g., T310) based on a predefined criterion, and apply the changed or deleted setting based on the second setting information to the radio link monitoring. The second timer can be started and the second setting information can be applied simultaneously, or the second timer can be started first and then the second setting information can be applied. The present invention is not limited thereto.

[0068] 7 is a diagram illustrating another example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 7, after receiving the second configuration information, the terminal device can determine that there is at least one synchronization instruction. For example, the RRC layer can determine whether there is at least one synchronization instruction, or how many synchronization instructions there are, or how many consecutive synchronization instructions there are, based on an instruction from the physical layer. For specific details, please refer to the prior art. In this case, the terminal device can apply the configuration changed or deleted based on the second configuration information to the radio link monitoring.

[0069] In this embodiment, the terminal device may start the second timer based on a predefined first criterion, or based on a second criterion determined at least based on the second setting information, for example, the first criterion being that the number of consecutive out-of-sync indications is equal to a predefined first numerical value, and / or the second criterion being that the number of consecutive out-of-sync indications is equal to a second numerical value, and the second numerical value is determined at least based on the second setting information.

[0070] For example, the predefined first numerical value may be a constant (e.g., N310), or may be a numerical value determined from at least two candidate numerical values ​​based on a predefined root (e.g., a value selected from N310 and a value smaller than or proportionally reduced from N310, or a value selected from N310 and a value larger than or proportionally increased from N310). The second numerical value may be directly included in the second setting information or may be obtained according to a method included in the second setting information. For example, when the second setting information includes a proportional constant of 2 or 0.5, the second numerical value may be determined to be 2 or 0.5 times the value before receiving the second setting information.

[0071] 8 is a diagram illustrating another example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 8, before receiving the second configuration information, the terminal device starts a second timer, and when the second timer times out or stops, the terminal device can apply the configuration changed or deleted based on the second configuration information to the radio link monitoring.

[0072] 9 is a diagram illustrating another example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 9, before receiving the second configuration information, the terminal device starts a second timer. After receiving the second configuration information, the terminal device can determine that there is at least one out-of-sync indication. For example, the RRC layer can determine whether there is at least one out-of-sync indication, or how many out-of-sync indications there are, or how many consecutive out-of-sync indications there are, based on an indication from the physical layer. For specific details, please refer to the prior art. In this case, the terminal device can apply the configuration changed or deleted based on the second configuration information to the radio link monitoring.

[0073] The terminal device may further stop the second timer based on a predefined third criterion, or may stop the second timer based on a fourth criterion determined at least based on the second setting information, for example, the third criterion being that the number of consecutive synchronization instructions is equal to a predefined third numerical value, and / or the fourth criterion being that the number of consecutive synchronization instructions is equal to a fourth numerical value, and the fourth numerical value being obtained at least based on the second setting information.

[0074] For example, the predefined third numerical value may be a constant (e.g., N311), or the predefined third numerical value may be one numerical value determined from at least two candidate numerical values ​​based on a predefined rule (e.g., one selected from N311 and a value smaller than or proportionally reduced than N311, or one selected from N311 and a value larger than or proportionally increased than N311). The fourth numerical value may be directly included in the second setting information or may be obtained according to a method included in the second setting information. For example, when the second setting information includes a proportionality constant of 2 or 0.5, the fourth numerical value may be determined to be 2 or 0.5 times the value before receiving the second setting information.

[0075] The reconfiguration of this embodiment will be further explained below by taking the steps shown in FIG. 2 as an example.

[0076] 10 is another diagram illustrating a method for transmitting and receiving setting information in an embodiment of the present invention. As shown in FIG. 10, the method for transmitting and receiving setting information 1000 includes the following steps:

[0077] Step 1001: A network device sends first setting information for radio link monitoring to a terminal device, where the first setting information includes at least a threshold setting for the radio link monitoring and / or a resource setting for the radio link monitoring.

[0078] Step 1002: The network device sends second setting information for wireless link monitoring to the terminal device, where the second setting information is used to at least change or delete the setting of the first setting information.

[0079] As shown in FIG. 10, the method may further include the following steps:

[0080] Step 1003: determining whether the terminal device is in a stage other than the first stage in which it performs normal operation; Step 1004: After the other period ends, the terminal device applies the second setting information to wireless link monitoring.

[0081] In this embodiment, when the terminal device is in a normal operation stage, it can immediately apply the new configuration when it receives a message containing the reconfigured resource or threshold value. When the terminal device is in a stage other than the normal operation stage, it must wait for the end of the stage when it receives a message containing the reconfigured resource or threshold value, and then apply the new configuration.

[0082] For example, the stage other than the first stage of normal operation includes a second stage of wireless problem detection. When the terminal device is in the second stage (T2) of wireless problem detection, when it receives a message including a reconfiguration resource or a threshold, it can temporarily use the current configuration (e.g., first configuration information), and apply a new configuration (e.g., second configuration information) when it receives any one synchronization indication or when the number of consecutively received failure indications reaches a predetermined number M. The consecutively received failure indications include consecutive out-of-sync indications already received before receiving the second configuration information.

[0083] For example, M may be the same as the number (e.g., N310) of consecutive out-of-sync indications for starting a timer (e.g., T310) for radio problem recovery, or may be a different standard-defined or network device-configured number, e.g., a value smaller than the above-mentioned number N310, thereby allowing the procedure to terminate earlier, or a value larger than the above-mentioned number N31, thereby allowing for traffic with less stringent requirements on radio link quality.

[0084] In addition, for example, other steps than the first step of performing normal operation include a third step of performing wireless problem recovery. When the terminal device receives a message including a reconfiguration resource or a threshold while a recovery timer (e.g., T310) is running, the terminal device will temporarily use the current configuration (e.g., first configuration information), and when the timer expires, or when any one out-of-sync indication is received, or when the number of consecutively received synchronization indications reaches a predetermined number S, the terminal device can apply a new configuration (e.g., second configuration information).

[0085] For example, S may be the same as the number (e.g., N311) of consecutive synchronization indications for stopping a timer (e.g., T310) for radio problem recovery, or may be a different standard-defined or network device-configured number, e.g., a value smaller than the above-mentioned number N311, thereby allowing the procedure to terminate earlier, or a value larger than the above-mentioned number N311, thereby allowing for traffic with looser requirements on radio link quality.

[0086] Although the present invention has been described above using the steps shown in Figure 2 as an example, the present invention is not limited to this. For example, the start and stop of the timer is not limited to each step of wireless problem detection and may be applied to other scenarios. Furthermore, the above-mentioned M, S, etc. may also be applied to other scenarios.

[0087] This not only supports the introduction of beams and different traffic with different radio link qualities, but also improves the flexibility and accuracy of the configuration for radio link monitoring, and is easy to implement, and by applying the reconfiguration at an appropriate time, it can reduce the impact on the procedure of triggering RLM or RLF, allowing the terminal device to more accurately evaluate the radio link quality.

[0088] The following explanation will be given using two examples.

[0089] For example, during a period when T310 is not running, when the UE receives the nth consecutive out-of-sync indication (where n is less than the number N310 of consecutive out-of-sync indications for triggering the start of a recovery timer) consecutively from the lower layer (e.g., physical layer) notification at the RRC layer, the UE receives a reconfiguration message, and among the RLM-related parameters included in the reconfiguration message, the resources for RLM are different from the current configuration, for example, because the network device again configures resources corresponding to the new serving beam after the lower layer successfully completes beam failure recovery.

[0090] If the next instruction from the lower layer is a synchronization instruction, the RRC layer of the UE applies the resource configuration in the reconfiguration message; if the next instruction from the lower layer is still an out-of-sync instruction and n+1 is less than N310, the UE continues to use the previously configured resource for RLM, and repeatedly receives and judges instructions, and once it receives the N310th out-of-sync instruction or a synchronization instruction, the RRC layer of the UE applies the resource configuration in the reconfiguration message. In this way, the problem of inaccurate judgment due to radio link problem detection using different resources in the same step can be avoided.

[0091] Also, for example, during the period T310 is running, the UE receives a reconfiguration message, and the IS / OOS threshold setting among the RLM-related parameters included in the reconfiguration message is changed. For example, the new setting is looser due to a lower reliability requirement. At this time, the UE does not apply the threshold setting in the reconfiguration message, but continues to receive instructions from lower layers, and can determine successful recovery based on a number of consecutive synchronization indications that is smaller than N311. Here, using fewer consecutive synchronization indications can compensate for the inaccuracy caused by not being able to make a judgment using a looser threshold.

[0092] The above describes how the radio link monitoring is reconfigured using the second configuration information. The terminal device may further determine a different threshold value by itself.

[0093] In one implementation, the terminal device may determine a different threshold value by itself and then apply the second radio link monitoring threshold value to radio link monitoring, and the terminal device may further perform at least one of the following actions, such as re-counting consecutive out-of-sync indications; resetting the consecutive out-of-sync indication counter; re-counting consecutive in-sync indications; resetting the consecutive in-sync indication counter; and restarting the first timer.

[0094] In one implementation, the terminal device can perform the radio link monitoring based on the first configuration information and a first radio link monitoring threshold, and can determine a second radio link monitoring threshold based on a selection criterion, where the second radio link monitoring threshold is different from the first radio link monitoring threshold, and the selection criterion is predefined and configured for the terminal device by the network device. For example, the first configuration information can be used to configure the selection criterion.

[0095] 11 is another diagram illustrating a method for transmitting and receiving setting information in an embodiment of the present invention. As shown in FIG. 11, the method for transmitting and receiving setting information 1100 includes the following steps:

[0096] Step 1101: A network device sends first setting information for radio link monitoring to a terminal device, where the first setting information includes at least a threshold setting for the radio link monitoring and / or a resource setting for the radio link monitoring.

[0097] As shown in FIG. 11, the method may further include the following steps:

[0098] Step 1102: The terminal device performs the radio link monitoring based on the first setting information and a first radio link monitoring threshold; and Step 1103: The terminal device determines a second radio link monitoring threshold value based on the selection criteria.

[0099] This not only supports the introduction of beams and different traffic with different radio link qualities, but also improves the flexibility and accuracy of the settings for radio link monitoring. In addition, it is easy to implement, and the terminal device determines the threshold by itself, which reduces the impact on the procedure for triggering RLM or RLF, allowing the terminal device to more accurately evaluate the radio link quality.

[0100] 12 is a diagram illustrating another example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 12, before determining the second radio link monitoring threshold, the terminal device can determine that there is at least one out-of-sync indication, and the terminal device can determine and start a second timer based on a predefined criterion, and apply the second radio link monitoring threshold to the radio link monitoring.

[0101] The terminal device may start the second timer based on a fifth predefined criterion, or the terminal device may start the second timer based on a sixth criterion, where the sixth criterion is determined based at least on the first setting information. For example, the fifth criterion is that the number of consecutive out-of-sync indications is equal to a fifth predefined numerical value, or the sixth criterion is that the number of consecutive out-of-sync indications is equal to a sixth numerical value, where the sixth numerical value is determined based at least on the first setting information.

[0102] For example, the predefined fifth numerical value may be a constant, or may be a numerical value determined from at least two complementary numerical values ​​according to a predefined rule. For specific details of the above-mentioned fifth criterion, sixth criterion, fifth numerical value, and sixth numerical value, please refer to the previous implementation method, and may be the same as the first criterion, first numerical value, etc.

[0103] 13 is a diagram illustrating an example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 13, before determining a second radio link monitoring threshold, the terminal device can determine that there is at least one out-of-sync indication, and after determining the second radio link monitoring threshold, the terminal device can determine that there is at least one in-sync indication, and the terminal device applies the second radio link monitoring threshold to the radio link monitoring.

[0104] 14 is a diagram illustrating another example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 14, before determining the second radio link monitoring threshold, the terminal device starts a second timer, and when the second timer expires or stops, the terminal device applies the second radio link monitoring threshold to radio link monitoring.

[0105] The terminal device may stop the second timer based on a seventh predefined criterion, or the terminal device may stop the second timer based on an eighth criterion, the eighth criterion being determined based at least on the first setting information. For example, the seventh criterion is that the number of consecutive synchronization instructions is equal to a seventh predefined value, or the eighth criterion is that the number of consecutive synchronization instructions is equal to an eighth value, and the eighth value is obtained based at least on the first setting information.

[0106] For example, the predefined seventh numerical value may be a constant, or may be a numerical value determined from at least two candidate numerical values ​​based on a predefined rule. For specific details of the seventh criterion, the eighth criterion, the seventh numerical value, and the eighth numerical value, please refer to the previous implementation method, and may be the same as the first criterion, the first numerical value, etc.

[0107] 15 is a diagram illustrating another example of application of configuration information in an embodiment of the present invention. For example, as shown in FIG. 15, before determining the second radio link monitoring threshold, the terminal device starts a second timer. After determining the second radio link monitoring threshold, the terminal device can determine that there is at least one out-of-sync indication, and the terminal device applies the second radio link monitoring threshold to radio link monitoring.

[0108] In the case where the terminal device determines a different threshold by itself and then applies the second radio link monitoring threshold to radio link monitoring, the terminal device may determine the timing to apply the threshold according to the steps shown in Figure 2, and the specific content can refer to the previous implementation method, but the present invention is not limited thereto and can also be applied to other scenarios.
