[0083] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 , wherein the network device includes at least one of the following: an access network device and a core network device.

[0084] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0087] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0088] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0089] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0090] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 .

[0091] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0092] In some embodiments, the terminal may perform Radio Link Monitoring (RLM) measurements on the primary cell (PCell) and / or the primary secondary cell (PSCell) to determine the quality of the serving cell, for example, to determine whether it is synchronized. For example, the terminal may determine synchronization (synch-in) or non-synchronization (synch-out, also referred to as loss of synchronization or desynchronization) based on the RLM measurement results.

[0093] In some embodiments, the terminal may compare the measurement results obtained at all measurement moments in the first RLM measurement period with the synch-out threshold. If the measurement results obtained at all measurement moments in the first RLM measurement period are worse than the synch-out threshold (for example, the measurement results are less than the synch-out threshold), it may be determined that there is no synchronization.

[0094] In some embodiments, the terminal may compare the measurement result obtained at at least one measurement moment in the second RLM measurement period with the synch-in threshold. If the measurement result obtained at at least one measurement moment in the second RLM measurement period is greater than the synch-in threshold (for example, the measurement result is less than the synch-in threshold), synchronization may be determined.

[0095] In some embodiments, the first RLM measurement period may be referred to as T_in, and the second RLM measurement period may be referred to as T_out. T_in and T_out may be periods of the same length, or T_in and T_out may be periods of different lengths, which is not limited in this disclosure. The RLM measurement period described in subsequent embodiments may include at least one of the first RLM measurement period and the second RLM measurement period.

[0096] In some embodiments, the terminal measures the RLM reference signal during the RLM measurement period to obtain the above measurement results. For example, if the RLM reference signal configured by the network device is a synchronization signal block (SS (Synchronization Signal) and PBCH (Physical Downlink Broadcast Channel) Block, SSB), then the terminal can measure the SSB during the RLM measurement period to obtain the above measurement results.

[0097] In some embodiments, an SSB occupies four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain, including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a PBCH.

[0098] In some embodiments, the NR system supports five SSB time domain transmission scenarios (cases), namely case A (SCS = 15KHz, operating in frequency bands above 3GHz), case B (SCS = 30KHz, operating in frequency bands above 3GHz), case C (SCS = 30KHz, TDD and operating in frequency bands above 3GHz), case D (SCS = 120KHz, operating in FR2 frequency band), and case E (SCS = 240KHz, operating in FR2 frequency band). The time domain pattern of the case depends on factors such as the sub-carrier space (SCS) of the SSB, the operating frequency, the time division duplex (TDD) format, and the frequency division duplex (FDD) format. Different SSB cases correspond to the number of SSBs in an SSB burst and the time domain resource positions occupied in the burst. For example, the duration of the SSB burst is 5ms; for example, the transmission period of the SSB is 20ms. Furthermore, network devices can configure the SSB transmission period and time domain pattern using the relevant information carried in the system information block SIB1. The maximum SSB transmission period is 160ms. For different cases, the SSB pattern can refer to related technologies, such as the 3GPP protocol TS38.213, which will not be further described in this disclosure.

[0099] In some embodiments, for a terminal in the initial access stage, since the terminal has not yet determined the SSB transmission period, the SSB can be received according to a predefined transmission period (e.g., 20ms), and the SSB pattern can be determined based on the previous embodiment.

[0100] In some embodiments, for a terminal that has received SIB1, if SIB1 carries SSB-related transmission parameters (also referred to as configuration information), the terminal can determine the SSB transmission period and the index of the SSB in the SSB burst based on the SSB-related transmission parameters in SIB1, and then receive the SSB according to the SSB transmission period.

[0101] In some embodiments, when the network device configures the RLM reference signal to SSB, or the network device does not configure the RLM reference signal, but the reference signal associated with the transmission configuration indicator (TCI) of the control resource set (CORSET) is SSB, the terminal can measure the SSB within the RLM measurement period to obtain the above measurement results.

[0102] However, in some embodiments, the network device may adjust the SSB configuration information as needed, resulting in the SSB period and / or time domain position being different from those specified in the aforementioned embodiments. In this case, if the terminal continues to receive the SSB according to the pre-adjusted configuration information, the resulting RLM measurement results will be problematic. If the problematic RLM measurement results are sent to the network device, this may cause erroneous desynchronization or synchronization, affecting the communication quality of the network device.

[0103] FIG2 is an interactive schematic diagram illustrating a wireless link monitoring measurement method according to an embodiment of the present disclosure.

[0104] As shown in FIG2 , the wireless link monitoring measurement method may include the following steps:

[0105] In step S201, it is determined that there is an invalid synchronization signal block SSB opportunity within a radio link monitoring RLM measurement period.

[0106] In some embodiments, the terminal may receive an SSB transmitted by the network device during an SSB occasion within an RLM measurement period. For example, an RLM measurement period may include one or more SSB occasions. The RLM measurement period may be configured by the network device or may be agreed upon by a protocol, and the present disclosure is not limited thereto.

[0107] In some embodiments, the terminal may determine the SSB timing based on the above embodiments. For example, during the initial access phase, the terminal may determine the SSB timing based on a predefined SSB transmission period; for example, after receiving SIB1, if SIB1 carries SSB configuration information, the terminal may determine the SSB timing based on the SSB configuration information.

[0108] In some embodiments, the SSB timing may refer to the time domain position of the SSB, for example, may include the time domain position of the SSB corresponding to at least one SSB index in at least one SSB burst in at least one SSB transmission cycle.

[0109] In some embodiments, when the terminal does not receive the SSB at the determined SSB opportunity, the terminal may determine that the SSB opportunity is invalid.

[0110] In this case, the terminal can determine that the network device has adjusted the time domain position of the SSB or stopped sending the SSB. For example, the SSB enters on-demand mode, that is, the network device only sends the SSB when the terminal requests it to send the SSB. In this case, if the terminal still receives the SSB according to the time domain position before the adjustment, the obtained RLM measurement result will be problematic.

[0111] In some embodiments, the network device may adjust the time domain position of the SSB or stop sending the SSB when network energy saving (NES) is required, or may adjust the time domain position of the SSB in other situations, and the present disclosure does not limit this.

[0112] It should be noted that when the network device needs to enter NES mode, or has entered NES mode, in addition to adjusting the time domain position or stopping transmission for SSB, it can also adjust the time domain position or stop transmission for other signals. For example, other signals include at least one of the following: SIB1, and may also include other information, such as Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), other newly defined signals, such as signals composed of primary synchronization signal and secondary synchronization signal, discovery reference signal (DRS), etc.

[0113] In step S202, the terminal adjusts the RLM measurement mode.

[0114] According to an embodiment of the present disclosure, when the terminal determines that there is an invalid SSB opportunity within the RLM measurement period, the terminal can adjust the RLM measurement method. Accordingly, the terminal does not need to receive the SSB according to the invalid SSB opportunity, which may cause problems in the obtained RLM measurement results. This is conducive to ensuring that the RLM measurement results obtained by the terminal according to the adjusted RLM measurement method can be accurately used to judge desynchronization and synchronization.

[0115] The following uses several embodiments to illustrate how the terminal adjusts the RLM measurement mode.

[0116] In some embodiments, the terminal adjusts the RLM measurement mode including at least one of the following:

[0117] The terminal does not expect to perform RLM measurements based on SSB;

[0118] When performing RLM measurement within the RLM measurement period, the terminal ignores the invalid SSB opportunity;

[0119] The terminal does not perform RLM measurement during the RLM measurement period;

[0120] The terminal adjusts the RLM measurement period.

[0121] In some embodiments, the terminal adjusting the RLM measurement mode includes the terminal not expecting to perform RLM measurement based on SSB. In this case, if the terminal still needs to perform RLM measurement, the terminal may perform RLM measurement based on other reference signals other than SSB.

[0122] Although the network device adjusts the time domain position of the SSB or stops sending the SSB, resulting in invalid SSB opportunities in the RLM measurement period, there may be other RLM reference signals whose time domain positions the network device has not adjusted and which have not stopped sending. Therefore, the terminal can perform RLM measurement based on other RLM reference signals and still ensure accurate RLM measurement results.

[0123] For example, other reference signals include: CSI-RS. Of course, other reference signals used for RLM measurement are not limited to CSI-RS, and reference signals other than CSI-RS can also be used as needed, and this disclosure does not limit this.

[0124] In some embodiments, the CSI-RS is determined based on at least one of the following:

[0125] Configuration information of network devices;

[0126] The transmission configuration indication TCI of the control resource set CORESET.

[0127] In some embodiments, the terminal may determine CSI-RS resources (eg, time domain resources and / or frequency domain resources) based on configuration information sent by the network device, receive CSI-RS on the CSI-RS resources, and measure the received CSI-RS.

[0128] In this case, the network device may configure two sets of RLM reference signals for the terminal for RLM measurement, namely SSB and CSI-RS.

[0129] The network device can instruct (for example, through explicit signaling) the terminal that when the SSB is sent normally (for example, there is no invalid SSB opportunity within the RLM measurement period, and / or the terminal determines that the configuration information of the SSB has been adjusted), the RLM reference signal used by the terminal for RLM measurement is SSB. Then the terminal can use SSB for RLM measurement when the SSB is sent normally, and use CSI-RS for RLM measurement when the SSB is sent normally (for example, there is an invalid SSB opportunity within the RLM measurement period, and / or the terminal determines that the configuration information of the SSB has not been adjusted).

[0130] Alternatively, the terminal may determine, based on a protocol agreement, to use SSB for RLM measurement when SSB is sent normally, and to use CSI-RS for RLM measurement when SSB is not sent normally.

[0131] In some embodiments, the terminal may perform RLM measurement based on the CSI-RS associated with the TCI of the CORESET.

[0132] In this case, since the CSI-RS associated with the TCI of the CORESET is already known to the terminal, the network device may not need to provide the terminal with additional CSI-RS configuration information.

[0133] The network device can instruct (for example, through explicit signaling) the terminal that when SSB is sent normally, the RLM reference signal used by the terminal for RLM measurement is SSB. Then the terminal can use SSB for RLM measurement when SSB is sent normally, and use the CSI-RS associated with the TCI of CORESET for RLM measurement when SSB is sent normally.

[0134] Alternatively, the terminal may determine, based on protocol agreement, to use SSB for RLM measurement when SSB is sent normally, and to use CSI-RS associated with TCI of CORESET for RLM measurement when SSB is not sent normally.

[0135] The network device may optionally configure a TCI state for the CORESET. In the TCI, an associated parameter is a Quasi Co-Location (QCL) source, which is used to determine the downlink reference signal (DL reference signal) of the downlink beam. The QCL source may be an SSB or a CSI-RS. In this embodiment, the CSI-RS associated with the TCI of the CORESET may refer to the network device configuring the CSI-RS as a QCL source for the TCI of the CORESET. For example, the TCI of the CORESET may indicate an identifier of the CSI-RS as the QCL source, and the terminal may determine the CSI-RS associated with the TCI of the CORESET based on the identifier.

[0136] FIG3A is a schematic diagram of a synchronization signal block according to an embodiment of the present disclosure.

[0137] For example, the indexes of the four SSBs in an SSB burst are #0, #1, #2, and #3 respectively. The terminal uses the SSB with index #0 for RLM measurement, that is, RLM measurement is performed according to the SSB with index #0 in each SSB burst in a 20ms period. The synch-in and synch-out states can be judged according to the measurement results in the next cycle of the measurement operation.

[0138] As shown in FIG3A , the network device can adjust the time domain position of the SSB. For example, before the adjustment, the transmission period of the SSB is 20 ms, and each SSB burst includes 4 SSBs. After the adjustment, the transmission period of the SSB is 40 ms, and each SSB burst still includes 4 SSBs.

[0139] After the network device adjusts the time domain position of the SSB, the network device stops sending the SSB burst at the time domain position where the second SSB burst and the fourth SSB burst were originally sent in Figure 3A, so that the terminal cannot receive the SSB at the SSB opportunity indexed #0 in the time domain position of the second SSB burst and the fourth SSB burst. Therefore, it can be determined that there is an invalid SSB opportunity within the RLM measurement period.

[0140] The RLM measurement period may include two or four or other numbers of SSB periods before adjustment. Taking the RLM measurement period including two SSB periods before adjustment as an example, for example, the first SSB burst and the second SSB burst are located in the first RLM measurement period, and the third SSB burst and the fourth SSB burst are located in the second RLM measurement period.

[0141] Taking the first RLM measurement cycle as an example, before the network device adjusts the time domain position of the SSB, the terminal measures the SSB with index #0 in the first SSB burst and the second SSB burst in the first RLM measurement cycle at a period of 20ms, and determines the synch-in and synch-out states based on the measurement results.

[0142] After the network device adjusts the time domain position of the SSB, if the terminal still measures the SSB with index #0 in the first SSB burst and the second SSB burst in the first RLM measurement cycle according to a 20ms period, since the terminal cannot receive the SSB at the SSB timing with index #0 in the time domain position of the second SSB burst, the measurement result obtained by the terminal at the SSB timing with index #0 in the time domain position of the second SSB burst cannot accurately represent the current network situation, and there will be problems in judging the synch-in and synch-out states based on this.

[0143] According to an embodiment of the present disclosure, since the terminal cannot receive the SSB at the SSB opportunity indexed #0 in the time domain positions of the 2nd SSB burst and the 4th SSB burst, it can be determined that there are invalid SSB opportunities in the 1st RLM measurement period and the 2nd RLM measurement period, so that RLM measurement based on SSB is not expected, but RLM measurement is performed based on CSI-RS.

[0144] It should be noted that the terminal does not expect to perform RLM measurement based on SSB, and may not expect to perform RLM measurement based on SSB in all RLM measurement periods, or may not expect to perform RLM measurement based on SSB only in RLM measurement periods where there are invalid SSB opportunities.

[0145] In some embodiments, the terminal adjusting the RLM measurement mode includes the terminal ignoring the invalid SSB opportunity when performing RLM measurement within the RLM measurement period.

[0146] When the terminal determines that there is an invalid SSB opportunity in the RLM measurement period, it can still use SSB to perform RLM measurement, but it needs to ignore the invalid SSB opportunity and only perform RLM measurement based on the SSB in the valid SSB opportunity in the RLM measurement period.

[0147] It should be noted that this embodiment can be implemented independently, and the RLM measurement period can also be adjusted based on this embodiment. For details on adjusting the RLM measurement period, reference can be made to subsequent embodiments.

[0148] FIG3B is a schematic diagram of another synchronization signal block according to an embodiment of the present disclosure.

[0149] For example, the indexes of the four SSBs in an SSB burst are #0, #1, #2, and #3 respectively. The terminal uses the SSB with index #0 for RLM measurement, that is, RLM measurement is performed according to the SSB with index #0 in each SSB burst in a 20ms period. The synch-in and synch-out states can be judged according to the measurement results in the next cycle of the measurement operation.

[0150] As shown in Figure 3B, the network device can adjust the time domain position of the SSB. For example, before the adjustment, the transmission period of the SSB is 20ms, and each SSB burst includes 4 SSBs; after the adjustment, the transmission period of the SSB is 40ms, and each SSB burst still includes 4 SSBs.

[0151] After the network device adjusts the time domain position of the SSB, the network device stops sending the SSB burst at the time domain position where the second SSB burst and the fourth SSB burst were originally sent in Figure 3B, so that the terminal cannot receive the SSB at the SSB opportunity indexed #0 in the time domain position of the second SSB burst and the fourth SSB burst. Therefore, it can be determined that there is an invalid SSB opportunity within the RLM measurement period.

[0152] Taking the RLM measurement period before the four SSB periods are adjusted as an example, after the network device adjusts the SSB time domain position, if the terminal still measures the SSB with index #0 in the four SSB bursts within the RLM measurement period according to the 20ms cycle, the terminal cannot receive the SSB at the SSB timing with index #0 in the time domain positions of the second and fourth SSB bursts. Therefore, the measurement results obtained by the terminal at the SSB timing with index #0 in the time domain positions of the second and fourth SSB bursts cannot accurately represent the current network status, and there will be problems in determining the synch-in and synch-out status based on these results.

[0153] According to an embodiment of the present disclosure, since the terminal cannot receive the SSB at the SSB opportunity indexed #0 in the time domain positions of the 2nd SSB burst and the 4th SSB burst before adjustment, it can be determined that there is an invalid SSB opportunity in the RLM measurement period, and thus the SSB opportunity indexed #0 in the time domain positions of the 2nd SSB burst and the 4th SSB burst before adjustment can be ignored, and the SSB is only received at the SSB opportunity indexed #0 in the time domain positions of the 1st SSB burst and the 3rd SSB burst, and the RLM measurement result is determined based on the received SSB.

[0154] In some embodiments, adjusting the RLM measurement mode by the terminal includes adjusting the RLM measurement period. For example, adjusting the RLM measurement period includes one of the following: increasing the RLM measurement period by a first multiple; decreasing the RLM measurement period by a first multiple.

[0155] It should be noted that this embodiment can be implemented independently, or the invalid SSB opportunity can be ignored on the basis of this embodiment. For the content of ignoring the invalid SSB opportunity, please refer to the previous embodiment and will not be repeated here.

[0156] In some embodiments, the first multiple α may be configured by the network device, or may be determined based on a protocol agreement.

[0157] For example, the network device can configure different first multiples for the terminal for different SSB sending states (for example, before the time domain position of the SSB, after adjusting the time domain position of the SSB, before stopping sending the SSB, and after stopping sending the SSB), or can configure the same first multiples for the terminal.

[0158] For example, the method agreed upon in the protocol may include determining the first multiple by the ratio of the period of the SSB after adjustment to the period of the SSB before adjustment.

[0159] In some embodiments, adjusting the RLM measurement period includes adjusting the RLM measurement period according to the adjustment of the SSB opportunity (eg, determined according to the number of invalid SSB opportunities).

[0160] FIG3C is a schematic diagram of another synchronization signal block according to an embodiment of the present disclosure.

[0161] As shown in Figure 3C, the network device can adjust the time domain position of the SSB. For example, before the adjustment, the transmission period of the SSB is 20ms, and each SSB burst includes 4 SSBs; after the adjustment, the transmission period of the SSB is 40ms, and each SSB burst still includes 4 SSBs.

[0162] After the network device adjusts the time domain position of the SSB, the network device stops sending the SSB burst at the time domain position where the second SSB burst and the fourth SSB burst were originally sent in Figure 3C, so that the terminal cannot receive the SSB at the SSB opportunity indexed #0 in the time domain position of the second SSB burst and the fourth SSB burst. Therefore, it can be determined that there is an invalid SSB opportunity within the RLM measurement period.

[0163] For example, if the original RLM measurement period includes two SSB periods before adjustment, for example, the first and second SSB bursts are in the first RLM measurement period, and the third and fourth SSB bursts are in the second RLM measurement period. In each RLM measurement period, the terminal measures the SSB with index #0 in the two SSB bursts and determines the synch-in and synch-out states based on the measurement results.

[0164] After the network device adjusts the time domain position of the SSB, if the terminal still measures the SSB with index #0 in the two SSB bursts in each RLM measurement cycle, the measurement result obtained by the terminal by measuring the SSB with index #0 in the second SSB burst in the RLM measurement cycle cannot accurately represent the current network situation. Therefore, there will be problems in judging the synch-in and synch-out states based on this.

[0165] According to an embodiment of the present disclosure, since the terminal cannot receive the SSB at the SSB timing with index #0 in the time domain positions of the second SSB burst and the fourth SSB burst, it can be determined that the ratio of the adjusted SSB period to the SSB period before the adjustment is 2, and the RLM measurement period can be extended to twice the original RLM measurement period, so that the adjusted RLM measurement period can include the first SSB burst and the third SSB burst. In this case, the terminal does not need to adjust the measurement of SSBs in the RLM measurement period, but needs to adjust the timing of measuring SSBs as the RLM measurement period is adjusted. For example, the terminal can still measure the SSB with index #0 in two SSB bursts in the RLM measurement period, for example, measure the SSB with index #0 in the first SSB burst and the third SSB burst in the RLM measurement period, and / or ignore the measurement of the SSB with index #0 in the second SSB burst and the fourth SSB burst in the RLM measurement period. The measurement results obtained in this way can accurately represent the current network situation, and the synch-in and synch-out states can be accurately determined.

[0166] In some embodiments, the terminal adjusting the RLM measurement mode includes not performing RLM measurement during the RLM measurement period.

[0167] If the terminal determines that an invalid SSB opportunity exists in the RLM measurement period, the terminal may not perform RLM measurement during the RLM measurement period. In this case, if it is still necessary to determine the synch-in and synch-out states, the radio link monitoring measurement method further includes one of the following: determining that the terminal is in a synch-in state; and determining that the terminal is in an out-of-synch state.

[0168] That is, when the terminal does not perform RLM measurement within the RLM measurement period, it may be assumed that the terminal is in a synchronized state, or it may be assumed that the terminal is in an unsynchronized state.

[0169] Whether the default terminal is in a synchronous state or in an asynchronous state may be determined based on historical information or based on a protocol agreement.

[0170] For example, in the case of determination based on historical information, the terminal may determine the terminal state determined based on RLM measurement in one or more RLM measurement periods before the RLM measurement period in which the invalid SSB opportunity exists. If the terminal is in a synchronized state, then for the RLM measurement period in which the invalid SSB opportunity exists, it may still be determined that the terminal is in a synchronized state; if the terminal is in an out-of-sync state, then for the RLM measurement period in which the invalid SSB opportunity exists, it may still be determined that the terminal is in an out-of-sync state.

[0171] For example, based on the protocol agreement, when the terminal determines that there is an invalid SSB opportunity in the RLM measurement cycle, if the protocol stipulates that the terminal is in a synchronized state, then it can be determined that the terminal is in a synchronized state; if the protocol stipulates that the terminal is in a synchronized state, then it can be determined that the terminal is in an unsynchronized state.

[0172] In some embodiments, the terminal can receive indication information sent by the network device, and then determine the existence of invalid synchronization signal block SSB timing within the wireless link monitoring RLM measurement period based on the indication information of the network device, adjust the RLM measurement mode, or not adjust the RLM measurement mode.

[0173] The network device may send an indication to the terminal, where the indication information may indicate whether to adjust the RLM measurement mode when an invalid SSB opportunity exists within the RLM measurement period. If the terminal determines, based on the indication information, that an invalid SSB opportunity exists within the RLM measurement period, that the RLM measurement mode is adjusted, then the RLM measurement mode may be adjusted based on any of the foregoing embodiments; if the terminal determines, based on the indication information, that an invalid SSB opportunity exists within the RLM measurement period, that the RLM measurement mode is not adjusted, then the RLM measurement mode may not be adjusted based on the foregoing embodiments, but RLM measurement may still be performed according to the original SSB measurement method.

[0174] In some embodiments, the network device may further instruct the terminal, through indication information, on how to adjust the RLM measurement mode when an invalid SSB opportunity exists within the RLM measurement period. For example, one or more of the following four RLM measurement adjustment modes may be indicated: "the terminal does not expect to perform RLM measurement based on the SSB; when performing RLM measurement within the RLM measurement period, the terminal ignores the invalid SSB opportunity; the terminal does not perform RLM measurement within the RLM measurement period; the terminal adjusts the RLM measurement period." Thus, when an invalid SSB opportunity exists within the RLM measurement period, the terminal may adjust the RLM measurement mode according to the mode indicated by the network device.

[0175] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0176] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0177] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0178] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
