[0116] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0117] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0118] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home, but is not limited thereto.

[0119] In some embodiments, network device 102 includes, but is not limited to, at least one of access network device 102-1 and core network device 102-2.

[0120] In some embodiments, the access network device 102-1 is, for example, a node or device that connects a terminal to a wireless network.

[0122] In some embodiments, the access network device 102-1 may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. By adopting the CU-DU structure, the protocol layer of the access network device can be separated. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU. However, this is not the only possibility.

[0123] In some embodiments, the core network device 102-2 may be a single device comprising multiple network elements, or it may be multiple devices or a group of devices, each comprising some or all of the multiple network elements. Network elements may be virtual or physical.

[0127] In some embodiments, for monitoring link quality, beam quality, beam failure, and discovering new beams, various measurement configurations and procedures are defined, including at least one of the following:

[0128] Radio Link Monitoring (RLM) is configured via RadioLinkMonitoring Reference Signal (RS).

[0129] Beam reporting is configured via Channel State Information (CSI) configuration.

[0130] Monitor beam failure detection (BFD) by configuring the failure detection resource add mode list (failureDetectionResourcesToAddModeList).

[0131] Monitor candidate beam detection (CBD) via the candidate beam reference signal list (candidateBeamRSList).

[0132] In some embodiments, the network device is configured with multiple types of L1 measurements individually:

[0133] Beam reporting.

[0134] The beam reporting process involves the terminal measuring the Layer 1 Reference Signal Receiving Power (L1-RSRP) based on the reference signal configured in the network device, and then reporting the index or measurement value of at least one beam with the best signal quality.

[0135] Beam monitoring failed (BFD).

[0136] The BFD process involves the terminal performing low-level measurements based on the reference signal set set q0 configured by the network device. When the beam radio link quality of all resources in q0 falls below the threshold Qout, the Layer 1 radio carrier signal LR considers a beam failure to have occurred. L1 reports a Beam Failure Indication (BFI) to the Media Access Control (MAC) layer and increments the BFI counter (BFI COUNTER++). When a beam failure instance indication is reported from the lower layer, the monitoring beam failure timer (BeamFailureDetectionTimer) is started, and the BFI counter is set to 1. If the maximum beam failure instance count (beamFailureInstanceMaxCount) is reached before the BeamFailureDetectionTimer expires, a beam failure is considered, and the Beam Failure Recovery (BFR) process is triggered.

[0137] Beam failure recovery BFR.

[0138] BFD occurs in the primary cell (Pcell). The terminal triggers BFR by performing a Random Access (RA) procedure on the Pcell. The terminal needs to perform candidate beam detection to perform BFR. After the RA procedure is completed, BFR is completed in the PCcell.

[0139] BFD occurs in the secondary cell (Scell). The terminal triggers BFR by sending a Media Access Control-Control Element (MAC CE) signal. The terminal then selects a suitable beam for the Scell ​​and includes this signal in the BFR MAC CE before sending it to the network device. Once a new uplink grant (UL grant) for sending the BFR MAC CE is received on the Physical Downlink Control Channel (PDCCH), the BFR for the Scell ​​is completed.

[0140] Radio Link Monitoring (RLM)

[0141] RLM primarily monitors downlink quality based on reference signals. The terminal monitors the network according to the RLM reference signal resources configured for it. If multiple measured signals fall below a certain threshold, the physical layer will send an RLM out-of-synchronous (OOS) signal to the higher layers.

[0142] In some embodiments, network devices may be configured separately for multiple types of L1 measurement processes. However, in reality, these measurement tasks are similar, leading to potential overlap in measurement resources, thus eliminating the need for multiple sets of resources. For example, beam reporting and beam recovery monitoring overlap, both aiming to find and report good beams. Furthermore, beam failure and link failure processes are also repetitive; link failure is a larger set of beam failures, and it occurs when all beams are potentially at risk of failure.

[0143] In some embodiments, the beam failure and / or recovery monitoring process cannot monitor beam changes in real time.

[0144] If the Reference Signal (RS) monitored during BFD is configured by Radio Resource Control (RRC), it may not reflect changes in the currently used beam in a timely manner. For example, the beam for which the Transmission Configuration Indicator (TCI) state activation has changed, but the RRC configuration remains unchanged, and the terminal is still monitoring the old TCI state. Furthermore, if BFD does not configure RS, the terminal will monitor the default TCI state corresponding to the PDCCH, but the quality of this TCI state is not reported to the network equipment in a timely manner. The terminal can only passively wait for a beam failure to occur before initiating the BFR procedure.

[0145] The RS corresponding to the candidate beam used in the BFR process is also configured with RRC, and similarly, it cannot reflect the candidate beam to be examined in real time.

[0146] In some embodiments, beam reconstruction or cell handover has a long delay.

[0147] During beam failure detection, the terminal L1 only sends instructions to the higher layer and does not notify network devices. Once a threshold is reached, BFR is initiated directly to search for candidate beams, and then the terminal initiates the RA procedure (in PCell). Initiating the RA procedure for reconstruction is time-consuming.

[0148] To improve the reliability of Layer 1 measurement configuration and save configuration resources, this disclosure provides the following communication methods, terminals, network devices, systems, and storage media.

[0149] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0150] In step S2101, network device 102 sends first configuration information to terminal 101.

[0151] In some embodiments, terminal 101 receives first configuration information.

[0152] In some embodiments, the first configuration information is used to configure a first reference signal. The first reference signal may correspond to multiple types of Layer 1 measurements, that is, the first reference signal is a reference signal configured by the network device 102 for multiple types of Layer 1 measurements.

[0153] In one example, the multi-class Layer 1 measurement includes at least two of the following: beam reporting, beam failure monitoring (BFD), candidate beam monitoring (CBD), and radio link monitoring (RLM).

[0154] For example, beam reporting involves terminal 101 performing L1-RSRP measurements based on reference signals configured by network device 102, and then reporting the index or measurement value of at least one beam with the best signal quality.

[0155] For example, BFD refers to the terminal 101 performing low-level measurements based on the reference signal set set q0 configured by the network device 102. When the beam radio link quality of all resources in q0 is lower than the threshold Qout, the LR considers a beam failure to have occurred. The L1 reports the BFI to the MAC layer and increments the BFI counter. When a beam failure instance indication is reported from the low-level layer, the BeamFailureDetectionTimer is activated, and the BFI counter is set to 1. If the maximum beam failure instance count (beamFailureInstanceMaxCount) is reached before the BeamFailureDetectionTimer expires, then a beam failure is considered.

[0156] For example, CBD means that if beam failure occurs in the primary cell, terminal 101 triggers beam failure recovery by performing an RA procedure in the primary cell. Terminal 101 needs to select a candidate beam for BFR and complete the RA procedure to determine that the BFR of the primary cell is complete. If beam failure occurs in the secondary cell, terminal 101 triggers BFR by sending a BFR MAC CE. Terminal 101 selects a suitable beam (or candidate beam) for the secondary cell and sends the selection result to network device 102 in the BFR MAC CE. When the PDCCH receives the new uplink authorization for sending the BFR MAC CE, it is determined that the beam failure recovery of the secondary cell is complete.

[0157] For example, RLM refers to terminal 101 detecting downlink quality based on a reference signal. If multiple measurement signals are below the target, an RLM OOS is sent to a higher layer. In some embodiments, the first reference signal may include a common reference signal, which is a common reference signal corresponding to at least two types of Layer 1 measurements out of multiple types of Layer 1 measurements.

[0158] For example, the first reference signal includes a common reference signal for multiple types of Layer 1 measurements. At this time, the terminal 101 can use this first reference signal when performing any type of Layer 1 measurement.

[0159] In some embodiments, the first reference signal may include a dedicated reference signal, which is a dedicated reference signal corresponding to one type of Layer 1 measurement among the multiple types of Layer 1 measurements.

[0160] For example, the first reference signal may include a dedicated reference signal for each type of Layer 1 measurement. Accordingly, when terminal 101 performs a type of Layer 1 measurement, it uses the dedicated reference signal corresponding to that type of Layer 1 measurement.

[0161] In some embodiments, the first reference signal may include a common reference signal and a dedicated reference signal.

[0162] For example, the first reference signal may include a common reference signal configured for two types of Layer 1 measurements, and separate dedicated reference signals configured for the other two types of Layer 1 measurements. Assume the first reference signal includes a common reference signal #1 for beam reporting and CBD, a dedicated reference signal #1 for BFD, and a dedicated reference signal #2 for RLM.

[0163] It is understandable that if network device 102 is configured with common reference signal #1 for beam reporting, then there is no need to configure a reference signal separately for CBD, and CBD can directly use the beam to report the corresponding common reference signal #1.

[0164] For example, the first reference signal may include a common reference signal for three types of Layer 1 measurement configurations, and a dedicated reference signal for another type of Layer 1 measurement configuration. Assume the first reference signal includes a common reference signal #1 for beam reporting, CBD, and RLM, and a dedicated reference signal #1 for BFD.

[0165] The above is merely an illustrative example and is not intended to limit the scope of this disclosure.

[0166] In some embodiments, network device 102 may not configure a corresponding reference signal for a specific Layer 1 measurement. In this case, terminal 101 may use a default reference signal, such as a second reference signal. The second reference signal may correspond to a first Transmission Configuration Indication (TCI) state, which is associated with the physical downlink channel being used by the terminal. The physical downlink channel includes, but is not limited to, at least one of Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH). Specific solutions will be described in subsequent embodiments and will not be described here.

[0167] In some embodiments, the first reference signal may include, but is not limited to, at least one of the following: Channel State Information-Reference Signal (CSI-RS); Synchronization Signal / PBCH Block (SSB); Demodulation Reference Signal (DMRS).

[0168] In some embodiments, network device 102 may send first configuration information to terminal 101 based on its own policies and / or its own implementation.

[0169] In some embodiments, network device 102 may send first configuration information to terminal 101 when configuring terminal 101 to perform at least one of multiple types of Layer 1 measurements.

[0170] In some embodiments, network device 102 may send first configuration information to terminal 101 based on a request from terminal 101.

[0171] The above is merely an illustrative example, and this disclosure does not limit the event or timing that triggers the network device 102 to send the first configuration information to the terminal 101.

[0172] In step S2102, network device 102 sends second configuration information to terminal 101.

[0173] In some embodiments, terminal 101 receives second configuration information.

[0174] In some embodiments, the second configuration information is used to configure the transmission method of the first measurement result.

[0175] In one example, the first measurement result is the measurement result obtained by terminal 101 after performing the multi-layer 1 measurement based on the first reference signal. The specific content of the first measurement result will be introduced in subsequent steps and will not be introduced here.

[0176] In some embodiments, the transmission method of the first measurement result may include, but is not limited to, at least one of the following: periodically transmitting the first measurement result; non-periodically transmitting the first measurement result; or transmitting the first measurement result based on an event.

[0177] In one example, if the transmission method of the first measurement result includes periodic transmission of the first measurement result, the second configuration information can be used to configure the periodic information of the transmission of the first measurement result, including but not limited to the period duration, the start time unit position, etc.

[0178] In one example, if the transmission method of the first measurement result includes non-periodic transmission of the first measurement result, the second configuration information can be used to configure the resources for transmitting the first measurement result.

[0179] In one example, the transmission method of the first measurement result includes transmitting the first measurement result based on an event. The event can be agreed upon by a protocol and / or configured by second configuration information. This disclosure does not limit this. When the event is satisfied, the terminal 101 sends the first measurement result to the network device 102.

[0180] The event may include, but is not limited to, a measurement value of the first beam being less than or equal to a threshold value. The first beam may include, but is not limited to, at least one of the following: the beam used by the physical downlink channel; and a configuration beam corresponding to one type of Layer 1 measurement among the multiple types of Layer 1 measurements. The configuration beam refers to the beam corresponding to or indicated by the Layer 1 measurement configuration. For example, the beam corresponding to the measurement reporting configuration may be the beam corresponding to CSI-RS, the beam corresponding to the BFD configuration may refer to the beam corresponding to the reference signal included in the BFD configuration, the beam indicated by the CBD configuration may refer to the candidate beam configured in the CBD configuration, and the beam corresponding to the RLM configuration may be...

[0181] For example, for beam reporting, the event may include: the measured value of the configured beam corresponding to the measurement report is less than or equal to the threshold value Q1.

[0182] For example, for BFD, the event may include, but is not limited to, the measured value of the configuration beam corresponding to BFD being less than or equal to the threshold value Q2, and / or, the measured value of the beam used by the physical downlink channel currently being used by terminal 101, such as PDCCH or PDSCH, being less than or equal to the threshold value Q3.

[0183] For example, for CBD, the event may include, but is not limited to, the measured value of the configuration beam corresponding to CBD being less than or equal to the threshold value Q4.

[0184] For example, for RLM, the event may include, but is not limited to, the measured value of the configuration beam corresponding to the RLM being less than or equal to the threshold value Q5.

[0185] In one example, the threshold values ​​mentioned above may include at least one of the following: Signal to Interference plus Noise Ratio (SINR); Block Error Rate (BLER); Layer 1 Reference Signal Received Power (L1-RSRP).

[0186] The types of Q1, Q2, Q3, Q4, and Q5 mentioned above can be agreed upon by the protocol, determined by terminal 101 based on a predefined method, and / or configured by network device 102. The types can be the same or different. If the types are the same, for example, both are SINR, the values ​​can be the same or different. This disclosure does not limit this.

[0187] In step S2103, terminal 101 determines the first measurement result.

[0188] In some embodiments, terminal 101 may perform the multi-layer 1 measurement based on the first reference signal to determine the first measurement result.

[0189] In some embodiments, the first measurement result may include, but is not limited to, at least one of the following: the measurement value of the first beam; the index of at least one second beam; the measurement value of each second beam in at least one second beam; and first indication information.

[0190] In one example, the first beam includes the beam used by the physical downlink channel, such as the beam used by the PDCCH or PDSCH.

[0191] In one example, at least one second beam refers to at least one beam determined based on one type of Layer 1 measurement among the multiple types of Layer 1 measurements.

[0192] For example, the at least one second beam includes at least one of the following: at least one beam determined by performing the beam reporting; at least one beam failure; at least one beam failure predicted; at least one beam used for beam recovery; at least one beam predicted for beam recovery; at least one beam failure; at least one beam failure predicted; at least one beam recovery predicted; at least one beam predicted for link recovery.

[0193] For example, for beam reporting, at least one second beam may include the first N beams selected in descending order of measured values.

[0194] For example, for BFD, at least one second beam may include at least one beam that experiences beam failure at the current time point t, and / or may include a beam that has failed between the current time point t and a future time point (t+T). during At least one beam is about to fail within the time period between ( ).

[0195] For example, for CBD, at least one second beam may include at least one beam that undergoes beam recovery at the current time point t, and / or include beams that are between the current time point t and some future time point (t+T). during At least one beam that is about to recover within the time period between ( ).

[0196] For example, for RLM, at least one second beam may include at least one of the following: at least one beam where a link failure occurs at the current time t; or a beam between the current time t and a future time (t+T). during At least one beam that is about to experience link failure within the time period between (t and t); at least one beam that experiences link recovery at the current time t; and at least one beam that experiences link recovery between the current time t and some future time (t+T). during At least one beam that is about to experience link recovery within the time period between ( ).

[0197] The measured values ​​may include, but are not limited to, at least one of the following: SINR value, BLER value, and L1-RSRP value.

[0198] The first indication information can be used to indicate at least one of the following: a link failure has occurred; a link recovery has occurred; a link failure is predicted to occur; a link recovery is predicted to occur.

[0199] In this context, "link failure" can refer to a link failure occurring at the current time point t.

[0200] Link recovery can refer to a link failure occurring at the current time point t.

[0201] The prediction of link failure can refer to the time between the current time t and some future time (t+T). during A link failure is expected to occur within the time period between ( ).

[0202] Among them, predicting link recovery can refer to the time from the current time t to some future time (t+T). during Link recovery is expected to occur within the time period between ) and ).

[0203] In the event of a link failure or a predicted link failure, the first indication information can indicate RLF OOS.

[0204] In the event of link recovery or prediction of link recovery, the first indication information can indicate RLF synchronization (in synchronous, INS).

[0205] The above is merely an illustrative example, and this disclosure does not limit the specific information included in the first measurement result.

[0206] In step S2104, terminal 101 sends the first measurement result to network device 102.

[0207] In some embodiments, network device 102 receives a first measurement result.

[0208] In some embodiments, each first measurement result sent by terminal 101 to network device 102 includes the measurement result corresponding to each type of Layer 1 measurement among multiple types of Layer 1 measurements, that is, terminal 101 sends the measurement results of multiple types of Layer 1 measurements to network device 102 through one L1 report.

[0209] In some embodiments, each first measurement result sent by terminal 101 to network device 102 includes the measurement result corresponding to one type of Layer 1 measurement among multiple types of Layer 1 measurements. That is, terminal 101 reports the corresponding measurement results to network device 102 for beam reporting, BFD, CBD and RLM respectively.

[0210] In one example, the measurement results corresponding to beam reporting may include, but are not limited to, at least one of the following: the indexes of the N beams determined by performing the beam reporting; the measurement values ​​of the N beams.

[0211] In one example, the measurement results corresponding to BFD, CBD, and RLM may include, but are not limited to, at least one of the following: the measurement value of the first beam; the index and / or measurement value of the beam that experiences beam failure at the current time t; and the measurement results from the current time t to a future time point (t+T). duringThe index and / or measurement of the beam that is about to fail within the time period between t and t; the index and / or measurement of the beam used for beam recovery at the current time t; and the time period from the current time t to some future time point (t+T). during The index and / or measurement of the beam to be used for beam recovery during the time period between t and t; the index and / or measurement of the beam that experiences link failure at the current time t; and the time period from the current time t to some future time (t+T). during The index and / or measurement of the beam that is about to experience link failure within the time period between t and t; the index and / or measurement of the beam that will experience link recovery at the current time t; and the time period from the current time t to some future time point (t+T). during The index and / or measurement of the beam from which link recovery is about to occur within the time period between )

[0212] The above is merely an illustrative example, and this disclosure does not limit the method by which the terminal 101 reports the first measurement result.

[0213] In step S2105, network device 102 sends a second instruction message to terminal 101.

[0214] In some embodiments, terminal 101 receives second instruction information.

[0215] In some embodiments, the second indication information is used to instruct the terminal 101 to perform beam switching.

[0216] In some embodiments, when the first measurement result includes at least one of the measurement result corresponding to the BFD and the measurement result corresponding to the CBD, the network device 102 sends a second indication information to the terminal 101.

[0217] In one example, the second indication information can be used to indicate the switched beam index, wherein the switched beam index can be the same as the index of the beam used for beam recovery in the first measurement result.

[0218] In step S2106, terminal 101 performs beam switching.

[0219] In some embodiments, beam switching may also be referred to as TCI state switching or beam indication, and this disclosure does not limit it.

[0220] In some embodiments, terminal 101 may perform beam switching based on second indication information.

[0221] In some embodiments, steps S2105 to S2106 are optional steps. For example, if the first measurement result does not include the measurement result corresponding to BFD and does not include the measurement result corresponding to CBD, steps S2105 to S2106 may not be executed.

[0222] In step S2107, network device 102 sends third instruction information to terminal 101.

[0223] In some embodiments, terminal 101 receives third instruction information.

[0224] In some embodiments, the third indication information is used to instruct the terminal 101 to perform cell handover.

[0225] In some embodiments, if the first measurement result includes the measurement result corresponding to RLM, for example, if a link failure has occurred or a link failure is predicted, the network device 102 sends a third indication message to the terminal 101.

[0226] In step S2108, terminal 101 performs cell handover.

[0227] In some embodiments, terminal 101 may perform cell handover based on third indication information.

[0228] In some embodiments, steps S2107 to S2108 are optional steps. For example, if the first measurement result does not include the measurement result corresponding to RLM, steps S2107 to S2108 may not be executed.

[0239] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method, which includes:

[0240] In step S2201, terminal 101 determines that network device 102 has not configured the reference signal corresponding to the BFD, and / or has not configured the reference signal corresponding to the RLM.

[0241] In some embodiments, if the terminal 101 does not receive the BFD configuration sent by the network device 102, it determines that the network device 102 has not configured the reference signal corresponding to BFD.

[0242] In some embodiments, if the terminal 101 does not receive the RLM configuration sent by the network device 102, it determines that the network device 102 has not configured the reference signal corresponding to the RLM.

[0243] In step S2202, terminal 101 determines the second reference signal.

[0244] In some embodiments, the second reference signal corresponds to a first transmission configuration indication (TCI) state, which is associated with the physical downlink channel used by the terminal.

[0245] The physical downlink channel includes, but is not limited to, at least one of PDCCH and PDSCH.

[0246] In some embodiments, terminal 101 determines the second reference signal when it determines that network device 102 has not configured the reference signal corresponding to the BFD and / or has not configured the reference signal corresponding to the RLM.

[0247] In some embodiments, the name of the second reference signal is not limited and can be interchanged with "default reference signal", "default configuration", etc.

[0248] In step S2203, terminal 101 determines the second measurement result.

[0249] In some embodiments, terminal 101 performs at least one of the BFD and the RLM based on the second reference signal to determine a second measurement result.

[0250] In some embodiments, the second measurement result may include, but is not limited to, at least one of the following: a measurement value of a first beam; an index of at least one second beam; a measurement value of each of the at least one second beam; and first indication information. The second beam may refer to at least one beam determined based on BFD and / or RLM.

[0251] For example, the contents of the first beam, the second beam, and the first indication information have been described in the foregoing embodiments and will not be repeated here.

[0252] In step S2204, terminal 101 sends the second measurement result to network device 102.

[0253] In some embodiments, network device 102 receives a second measurement result.

[0254] In some embodiments, each second measurement result sent by terminal 101 to network device 102 includes the measurement results corresponding to BFD and RLM, that is, terminal 101 sends the measurement results corresponding to BFD and RLM to network device 102 through one L1 report.

[0255] In some embodiments, each second measurement result sent by terminal 101 to network device 102 includes the measurement result corresponding to BFD or RLM, that is, terminal 101 reports the measurement results corresponding to BFD and RLM to network device 102 in batches.

[0256] In step S2205, network device 102 sends a second instruction message to terminal 101.

[0257] In some embodiments, terminal 101 receives second instruction information.

[0258] In some embodiments, the second indication information is used to instruct the terminal 101 to perform beam switching.

[0259] In some embodiments, when the second measurement result includes the measurement result corresponding to the BFD, the network device 102 sends the second indication information to the terminal 101.

[0260] In step S2206, terminal 101 performs beam switching.

[0261] In some embodiments, step S2206 is implemented in a similar manner to step S2106, and will not be described again here.

[0262] In step S2207, network device 102 sends third instruction information to terminal 101.

[0263] In some embodiments, terminal 101 receives third instruction information.

[0264] In some embodiments, the third indication information is used to instruct the terminal 101 to perform cell handover.

[0265] In some embodiments, if the third measurement result includes the measurement result corresponding to the RLM, the network device 102 sends third indication information to the terminal 101.

[0266] In step S2208, terminal 101 performs cell handover.

[0267] In some embodiments, step S2208 is implemented in a similar manner to step S2108, and will not be described again here.

[0268] In some embodiments, steps S2201 to S2208 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0269] In some embodiments, the execution order of steps S2201 to S2208 is not limited.

[0270] In the above embodiments, the network device does not need to be configured with at least one type of reference signal corresponding to Layer 1 measurement, which saves configuration resources and has high availability.

[0271] Figure 2C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2C, the embodiments of the present disclosure relate to a communication method, which includes:

[0272] In step S2301, terminal 101 determines the third measurement result.

[0273] In some embodiments, the third measurement result is the result obtained by merging the first measurement results corresponding to at least two types of Layer 1 measurements that meet the merging conditions.

[0274] In one example, terminal 101 can determine the measurement result corresponding to each type of layer 1 measurement based on the first reference signal or the second reference signal. The specific process of determining the measurement result has been described in the foregoing embodiments and will not be repeated here.

[0275] Furthermore, terminal 101 determines whether there are at least two types of Layer 1 measurements among the multiple types of Layer 1 measurements that satisfy the merging conditions. The merging conditions are the criteria for merging the measurement results.

[0276] For example, at least two types of Layer 1 measurements that satisfy the merging conditions may include the beam reporting and the CBD. Accordingly, the third measurement result may include at least an index of at least one third beam, which may include any of the following: at least one beam determined by performing the beam reporting; at least one beam recovery that has occurred; and / or, at least one beam recovery that has been predicted.

[0277] That is, the third measurement report may include only the measurement results reported by the beam or only the measurement results of the CBD.

[0278] For example, at least two types of Layer 1 measurements that meet the merging conditions include the BFD and the RLM, and the third measurement result may include fourth indication information; wherein the fourth indication information is used to indicate that a link failure has occurred or to predict that a link failure has occurred.

[0279] The above is merely an illustrative example. It is understood that even if the multi-class layer 1 measurement includes at least two types of layer 1 measurement that meet the merging conditions, the measurement results corresponding to the at least two types of layer 1 measurement that meet the merging conditions may not be merged. This disclosure does not limit this.

[0280] In step S2302, terminal 101 sends the third measurement result to network device 102.

[0281] In some embodiments, network device 102 receives a third measurement result.

[0282] In some embodiments, if at least one of the measurement results corresponding to BFD and CBD in the third measurement results is obtained, then steps S2105 to S2106 can be continued.

[0283] In some embodiments, if at least one of the measurement results corresponding to RLM in the third measurement result is obtained, then steps S2107 to S2108 can be performed.

[0284] In some embodiments, steps S2301 to S2302 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0285] In some embodiments, the execution order of steps S2301 to S2302 is not limited.

[0286] In the above embodiments, the terminal can merge the measurement results corresponding to at least two types of Layer 1 measurements that meet the merging conditions, saving reporting resources and improving availability.

[0304] Figure 3B is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 3B, this embodiment of the present disclosure relates to a communication method, which can be executed by a network device 102, and includes the following steps:

[0305] Step S3201: Send the first configuration information.

[0306] In some embodiments, terminal 101 sends a first measurement result to network device 102.

[0307] In some embodiments, network device 102 receives a first measurement result.

[0308] In some embodiments, step S3102 may refer to steps in other embodiments described before or after this embodiment, such as step S2101 in FIG2A and its optional implementation, and other related parts in the specification, which will not be repeated here.

[0309] Step S3202: Obtain the first measurement result.

[0310] In some embodiments, network device 102 receives a first measurement result sent by terminal 101, but is not limited thereto. Network device 102 may also receive a first measurement result from other entities, such as relay devices or other entities. In this case, step S3202 may be omitted.

[0315] In some embodiments, step S3202 may refer to steps in other embodiments described before or after this embodiment, such as step S2104 in FIG2A and its optional implementation, as well as other related parts in the specification, which will not be repeated here.

[0316] In some embodiments, steps S3201 to S3202 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0317] In some embodiments, the execution order of steps S3201 to S3202 is not limited.

[0318] In the above embodiments, the network device can uniformly configure the first reference signal for multiple types of Layer 1 measurements, avoiding the overlap of measurement resources, saving configuration resources, and achieving high availability.

[0319] The above process is further illustrated with examples below.

[0320] In this embodiment, during routine L1-RSRP measurement and reporting, the terminal simultaneously monitors the status of the RS corresponding to BFD and searches for candidate beams, promptly reporting various L1 results to the network. If a potential beam failure is detected, the network initiates a TCI state switch procedure to avoid the RACH procedure following BFR. If the UE also detects a possible RLF or RLM OOS, the UE can also report it promptly, and the network initiates a cell switch procedure in advance to avoid a degradation in the UE's data reception performance. The overall process is shown in Figure 4, including the following steps:

[0321] Step S4101: The network device uniformly configures reference signals for various L1 measurement types. The L1 measurement types include:

[0322] Type 1: Beam reporting.

[0323] Type 2: BFD.

[0324] Type 3: CBD.

[0325] Type 4: RLM.

[0326] Regarding the configuration of the reference signal, network devices can adopt different schemes:

[0327] Option 1 configures a common set of reference signals for all L1 measurement types. For example, it defines a set of reference signals that can be used for all four types of measurements mentioned above.

[0328] Option 2: Use a common set of reference signals for some categories. Alternatively, define separate reference signals for other categories.

[0329] For example, reference signals based on beam reporting can also be used to recover from beam failure (CBD), meaning the network no longer needs to configure separate reference signals for CBD. The network defines a set of reference signals that are used for both beam reporting and beam failure recovery.

[0330] If no reference signal is configured for BFD and RLM, the default reference signal is used. The default reference signal is the reference signal corresponding to the beam currently being used by the PDCCH or PDSCH.

[0331] Step S4102: Configure the network device to report various L1 measurements, including periodic, non-periodic, and condition / event-based reporting.

[0332] For reporting multiple L1 measurements, there are two possible solutions:

[0333] Option 1: In a single L1 report, the terminal uniformly reports multiple types of information, including a set of multiple L1 measurement values ​​or a subset of those values.

[0334] Option 1, the best N beam indices.

[0335] Option 2, the L1-RSRP values ​​corresponding to the best N beam indices.

[0336] Option 3: The L1-RSRP value corresponding to the beam currently being used by the PDCCH or PDSCH.

[0337] Option 4, now or from now on t+T during The index of beams that are about to fail within a given time frame.

[0338] Option 5, now or from now on t+T during The L1-RSRP value corresponding to the beam index that is about to fail within a certain time.

[0339] Option 6, now or from now on t+T during The time period can be used as a beam index for beam recovery.

[0340] Option 7, now or from now on t+T during The L1-RSRP value corresponding to the beam index that can be used for beam recovery within a given time period.

[0341] Option 8, now or from now on t+T duringAn RLF OOS (link failure) or RLF INS (link recovery) is expected to occur within a certain timeframe.

[0342] Option 2: The terminal reports multiple measurement results respectively.

[0343] For example, when a terminal reports beams, it reports the beam indices corresponding to the best multiple beams, such as option 1 and / or option 2.

[0344] In addition, the terminal reports RS separately for BFD, CBD and RLM configurations, and the reported content includes some or a combination of options 3 to 8 mentioned above.

[0345] In step S4102, for condition / event-based reporting, it is also necessary to predefine the event type that triggers the reporting for each measurement.

[0346] For beam reporting, the event type that triggers the reporting is defined as follows:

[0347] The measured value of the configured beam corresponding to the beam report is less than or equal to the threshold value Q1.

[0348] For BFD, the event type that triggers reporting is defined as:

[0349] Option 1: The beam measurement value configured in BFD is below a certain threshold Q2.

[0350] Option 2: The measurement value corresponding to the beam currently being used by the PDCCH or PDSCH is lower than a certain threshold Q3.

[0351] The purpose of this threshold is to predict beam performance degradation before beam failure or link failure, and to initiate the TCI state switch in advance. The threshold is slightly higher than the threshold in BFR.

[0352] For CBD, the event type that triggers reporting is defined as:

[0353] Option 1: The beam measurement value reported by the CBD configuration or beam reporting is lower than a certain threshold Q4.

[0354] For RLM, the event type that triggers reporting is defined as:

[0355] Option 1: The measured value corresponding to the beam configured in the RLM is lower than a certain threshold Q5.

[0356] The purpose of this threshold is to predict the degradation of cell performance before link failure and initiate cell handover in advance. The threshold is slightly higher than the threshold of RLF.

[0357] The threshold can be defined by the terminal itself or configured by the network, and it can be based on the following options:

[0358] Option 1, based on SINR.

[0359] Option 2, based on BLER.

[0360] Option 3, based on L1-RSRP.

[0361] Therefore, if it is condition-based reporting, the results reported by the terminal may include results of one or more measurement types, depending on the threshold of different measurement types.

[0362] For example, the reported results include,

[0363] Case 1, which only includes beam reporting results.

[0364] Case 2 includes beam reporting results and beam failure measurement results.

[0365] Case 3 includes beam reporting results, beam failure measurement results, and beam recovery measurement results.

[0366] Case 4 includes beam reporting results, beam failure measurement results, beam recovery measurement results, and link failure measurement results.

[0367] Note that beam reporting results may no longer be displayed separately, but can be combined with beam failure and beam recovery measurement results.

[0368] In step S4103, the terminal performs various types of L1 measurements on the configured or default reference signal resources and reports them according to the reporting configuration of the network device.

[0369] If the network device is configured for conditional or event-based reporting, the terminal needs to compare the measurement results with a predefined threshold. The threshold definition has been described in step S4102. The purpose of this threshold is to predict the degradation of beam or cell performance before beam or link failure, and to initiate TCI state switching or cell handover in advance. The threshold is based on SINR or BLER and will be higher than the threshold in BFR.

[0370] In step S4104, based on the report result from the terminal in step S4103, the network device performs beam switching configuration or cell switching configuration in advance.

[0371] If the terminal previously reported a beam index and / or corresponding measurement value that may have caused beam failure, the network configures the terminal to perform a beam switch (TCI state switch, also known as beam indication). The new beam index is the beam index previously reported by the terminal that can be used for beam recovery.

[0372] If the terminal previously reported a possible link failure, the network device will configure the terminal to perform cell witching or handover in advance.

[0373] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0374] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0375] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
