[0050] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell.

The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.
[0051] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.
[0052] 1. Initial access process in NR system
[0053] In an NR system, the initial access process of a terminal device is accomplished by detecting the synchronization signal block (SSB or SS / PBCH block) on the synchronization raster. SSB is transmitted through the discovery signal transmission opportunity window (DBT) or SSB transmission opportunity window (SSB). The discovery signal transmission opportunity window or SSB transmission opportunity window occurs periodically, and the period can be configured by the network device through high-layer parameters.
[0054] One of the main functions of the SSB index is to allow the terminal device to obtain system timing information. In addition, the SSB index has another function, which is to indicate the Quasi Co-Location (QCL) relationship between SSBs. QCL means that the large-scale parameters of the channel experienced by the symbols on a certain antenna port can be inferred from the channel experienced by the symbols on another antenna port. The large-scale parameters may include delay spread, average delay, Doppler spread, Doppler frequency shift, and spatial reception parameters. Specifically for SSB, in the 5G NR system, the SSBs carried by different beams constitute an SSB burst set. Different SSB indices correspond to different SSB time domain position information within the burst set, and also correspond to specific SSB transmission beam information. SSBs with the same SSB index can be considered to have a QCL relationship; in other words, SSBs with the same SSB index experience the same or similar large-scale parameters of the channel. The terminal device can assume that the network device uses the same beam to transmit these SSBs; there is no QCL relationship between the SSBs corresponding to different SSB indices, because they may come from different transmission beams of the network device and experience different channel transmission characteristics.
[0055] During the initial access process, the terminal device attempts to search for the synchronization signal through the predefined possible time-frequency positions of the SSB, and demodulates the PBCH in the SSB after detecting the synchronization signal. The terminal device performs combined detection on the synchronization signals or PBCH with QCL relationship in multiple periods to improve the robustness of SSB detection. After detecting the SSB, the terminal device can obtain time and frequency synchronization, radio frame timing and cell ID (Identifier). The network device will configure the Type0-PDCCH CSS (Type0-Physical Downlink Control Channel Common Search Space) set through the MIB (Master Information Block) information in the SSB. The PDCCH transmitted in the Type0-PDCCH CSS set is used to schedule the PDSCH Physical Downlink Shared Channel carrying SIB1 (System Information Block 1). The terminal device can monitor the PDCCH candidates at the monitoring time of the corresponding Type0-PDCCH CSS set, thereby receiving the scheduling of the corresponding SIB1 message. Similarly, the terminal device can also receive the SIB1 message in a combined manner.
[0056] 2. RLM (Radio Link Monitoring) Process in NR System
[0057] In NR, RLM-RS (RLM Reference Signal, reference signal for RLM) is configured through high-layer signaling RadioLinkMonitoringRS (radio link monitoring reference signal). There are two types of RLM-RS that can be configured: CSI-RS (Channel State Information-Reference Signal, channel state information reference signal) and SSB. The configuration of an RLM-RS includes a resource index of a CSI-RS, or an index of an SSB. The measurement results of RLM-RS are used to evaluate the BLER (Block Error Rate) of the hypothetical PDCCH. The network device can configure multiple RLM-RSs on each BWP (Bandwidth Part) for the terminal device. Among the multiple configured RLM-RSs, the terminal device assumes that the RLM-RS has the same antenna port as the hypothetical PDCCH being evaluated.
[0058] For SSBs, the network device configures the index of one or more SSBs as RLM-RS for the terminal device. Due to multi-beam transmission in NR, when configuring RLM-RS, the network needs to configure multiple SSBs as RLM-RSs based on the beams serving the terminal device over a period of time. The RLM-RSs are used to measure the signal quality of these SSBs and determine the IS / OSS (In Synchronization / Out Of Synchronization) status.
[0059] For CSI-RS, since its resources are UE-specific, network equipment can more flexibly configure RLM-RS resources for a terminal device. The network equipment can also configure the index of one or more CSI-RS resources as RLM-RS for the terminal device, and also supports the measurement of channel quality of multi-beam transmission.
[0060] When the service cell of a terminal device is configured with multiple downlink BWPs, the terminal device only uses the RLM-RS configured on the activated BWP for RLM measurement; or when no RLM-RS is configured on the activated BWP, the CSI-RS corresponding to the activated TCI (Transmission Configuration Indicator) state corresponding to the CORESET (Control-Resource Set) used for PDCCH reception on the activated BWP is used as the RLM-RS for RLM measurement.
[0061] After configuring the RLM-RS, the UE measures the RLM-RS and compares the measurement results with the IS / OOS threshold to determine the IS / OOS status of the radio link. The UE then periodically reports the IS / OOS status evaluation results to higher layers. If the measurement result of any of the configured RLM-RSs exceeds the IS threshold, the physical layer reports the IS status to higher layers. If the measurement results of all configured RLM-RSs are below the OOS threshold, the physical layer reports the OOS status to higher layers. It can be seen that the reporting of the IS / OOS status is not based on the number of beams in the cell, that is, the number of configured RLM-RSs.
[0062] In the non-DRX (Discontinuous Reception) state, the IS / OOS status reporting period is the maximum value between the shortest period of all configured RLM-RS resource cycles and 10ms. In the DRX state, the IS / OOS status reporting period is the maximum value between the shortest period of all configured RLM-RS resource cycles and the DRX cycle.
[0063] The IS / OOS thresholds in NR's RLM are determined based on the BLER of a hypothetical PDCCH. NR supports two sets of hypothetical PDCCH BLERs. The first set of thresholds is consistent with LTE: the IS threshold corresponds to a hypothetical PDCCH BLER of 2%, and the OOS threshold corresponds to a hypothetical PDCCH BLER of 10%. The introduction of a second set of thresholds, which corresponds to a higher hypothetical PDCCH BLER, facilitates maintaining radio link connectivity even in locations with poor radio signal strength, avoiding connection failures caused by radio link failures, thereby facilitating service continuity for services such as VoIP (Voice Over Internet Protocol). The network configures the use of this set of hypothetical PDCCH BLERs through the RLM out-of-sync threshold (rlmInSyncOutOfSyncThreshold) signaling. The SINR (Signal to Interference Plus Noise Ratio) value corresponding to the IS / OOS BLER threshold is not directly defined in the NR standard. Each manufacturer determines its own UE IS / OOS threshold based on the hypothetical PDCCH BLER and the performance of the UE receiver.
[0064] The physical layer reports an IS / OOS indication to the upper layer each time. If the upper layer receives N310 consecutive OOS indications, it starts the radio link detection timer, indicating that a physical layer problem has been detected. While the radio link detection timer is running, if the upper layer receives N311 consecutive IS indications, it stops the radio link detection timer, indicating that the physical layer problem has been resolved. N310 and N311 are the configured times. If the radio link detection timer expires, it indicates that an RLF (Radio Link Failure) event has occurred.
[0065] When an RLF event occurs, the terminal device can declare RLF. The following reasons may cause the terminal device to declare RLF, for example, the radio link detection expires, the MCG MAC (Master Cell Group Media Access Control) indicates a random access problem (such as a random access problem caused by beam failure recovery or other reasons), the MCG RLC (Radio Link Control) reaches the maximum number of retransmissions, and the uplink LBT (Listen Before Talk) continues to fail.
[0066] In the MR-DC (Multi-Radio-DC) enhancement project, a fast MCG recovery feature was introduced to reduce service interruptions caused by radio link failures. When an MCG radio link fails, an indication is sent to the network via the SCG (Secondary Cell Group) link, triggering the network to quickly restore the MCG link.
[0067] 3. RRM (Radio Link Monitoring) Measurements in NR Systems
[0068] For wireless mobile communication systems, accurate measurement of cell quality and beam quality is fundamental to effective radio resource management and mobility management. For 5G NR, two main types of reference signals are currently considered for measurement: SSB and CSI-RS. For SSB-based measurements, network equipment configures SSB measurement resources for the UE via higher-layer signaling, allowing the UE to perform the corresponding measurements. For CSI-RS-based measurements, network equipment configures one or more CSI-RS resources for the UE to perform measurements via higher-layer signaling.
[0069] In the design of the measurement scheme based on CSI-RS, a special configuration information is introduced, namely the information indication of the SSB (Associated SSB) associated with the CSI-RS. When this parameter field is configured, the UE needs to first detect the SSB associated with this CSI-RS, determine the target cell through the SSB, and then determine the target CSI-RS resource position based on the target cell timing information, and finally measure the target CSI-RS to obtain the corresponding measurement results. In addition, if the UE fails to detect the SSB associated with a certain CSI-RS resource, then the CSI-RS resource will no longer need to be measured, thereby reducing the measurement complexity based on CSI-RS to a certain extent. If the information indication field of the associated SSB is not configured, it means that the UE can directly use the timing of the reference serving cell (refServCellIndex) indicated in the measurement configuration to determine the position of the CSI-RS resource, and then directly measure the CSI-RS resource without doing additional target cell synchronization signal detection.
[0070] With the above configuration parameters, the UE knows which reference signals should be measured within which time and frequency domain resources. The terminal device's co-frequency or inter-frequency measurements require sufficient reference signal samples to meet certain measurement accuracy requirements (such as RSRP (Reference Signal Received Power), RSRQ (Reference Signal Receiving Quality), and SINR measurement accuracy), and then evaluate the relevant measurement results and report them to the network.
[0071] In a conditional handover, the network pre-configures candidate target cells and handover command information to the terminal device. When specific conditions are met, the terminal device can autonomously execute the configuration in the handover command and directly initiate handover access to the target cell that meets the conditions. Because the terminal device no longer triggers measurement reporting when the handover conditions are met, and the terminal device has already obtained the configuration in the handover command, it avoids the possibility of measurement reporting or handover command failure during the handover process, thereby improving the handover success rate.
[0072] In the MR-DC enhancement project, in order to improve the service performance in the MR-DC mode, the function of quickly establishing SCell / SCG (Secondary Cell / SCG secondary cell / secondary cell group) is supported, that is, the terminal device is allowed to perform measurements in the idle state or inactive state, and report the measurement results to the network side immediately after entering the RRC (Radio Resource Control) connection state, so that the network side can quickly configure and establish SCell / SCG.
[0073] In the SCell Dormancy topic, when the SCell / SCG is activated but no data is being transmitted, a dedicated Dormant BWP is configured via RRC. This means that the UE does not monitor the PDCCH on this BWP and only performs CSI measurements and reporting, thus saving power. When data transmission is required, dynamic indication can be used to quickly switch to the active state, allowing for rapid service recovery.
[0074] 4. BFR (Beam Failure Recovery) mechanism in NR systems
[0075] In the NR system, analog beamforming technology uses phase shifters to change the phase of the corresponding channels of each antenna, allowing a group of antennas to form beams in different directions. This allows for cell coverage through beam sweeping, which uses beams corresponding to different directions at different times to cover different areas of the cell.
[0076] To improve the robustness of high-frequency analog beam transmission, when the current beam transmission quality deteriorates to a certain level, the terminal device proactively searches for a new beam with better link quality and notifies the network, thereby reestablishing a high-quality, reliable communication link through the new beam. This process is called the BFR mechanism, or beam recovery mechanism for short.
[0077] The beam failure recovery process is designed for downlink transmit beams and does not consider blocked uplink transmit beams. This is because if downlink communication quality is good, the network can issue instructions to the terminal to switch to a better uplink transmit beam for transmission. However, if downlink communication quality is poor, the terminal may not receive the network's instructions, and thus cannot effectively communicate with the terminal to determine a new beam pairing.
[0078] In the NR system, the beam failure recovery mechanism mainly consists of four steps:
[0079] ●Beam Failure Detection (BFD)
[0080] Beam failure measurement and determination is based on the link quality of the PDCCH channel. This uses the hypothetical PDCCH BLER as a metric for beam failure detection. Because the actual BLER of PDCCH transmissions cannot be directly determined, terminal devices infer the corresponding possible BLER based on the measured SINR. This is called the hypothetical PDCCH BLER.
[0081] Only a single-port periodic CSI-RS can be used for beam failure detection. Specifically, the network device can directly and explicitly configure the periodic CSI-RS for beam failure detection through signaling; or, if the network device does not use explicit configuration, the terminal uses the periodic CSI-RS in the activated TCI-state state of the CORESET corresponding to the PDCCH channel for beam failure detection.
[0082] The physical layer detects the assumed BLER of the PDCCH corresponding beam. If the assumed BLER of all PDCCH beams is lower than the specified threshold, it is recorded as a beam failure instance (BFI) and reported to the MAC. The physical layer needs to report to the MAC periodically. If no report is made at a certain time, it is assumed that there is no BFI.
[0083] The MAC layer maintains the beam failure detection timer (beamFailureDetectionTimer) and beam failure counter (BFI_COUNTER). To ensure the reliability of beam failure detection, each time the MAC layer receives a BFI report, it starts or restarts the beam failure detection timer and increments the beam failure counter by 1. If the beam failure detection timer expires, the terminal resets the counter to 0, ensuring that beam failure is determined based on continuous BFI reports. If the beam failure counter reaches the specified maximum value while the timer is running, the terminal considers a beam failure to have occurred.
[0084] ●NBI (New Beam Identification)
[0085] ○ The terminal measures a set of candidate beams and selects the beam that meets a certain threshold as the new beam.
[0086] ●BFRQ (Beam Failure Recovery Request)
[0087] ○ For the primary cell (PCell) and the secondary primary cell (PSCell),
[0088] The terminal initiates a beam failure recovery request (BFRQ) process through the PRACH (Physical Random Access Channel), notifying the network device of a beam failure and reporting a new beam.
[0089] □When a beam failure occurs, the terminal triggers a random access process and indicates to the network device through random access MSG1 that the terminal has experienced a beam failure and the new beam information selected by the terminal. Specifically, the network device preconfigures a set of candidate beams (such as CSI-RS signals and / or SSBs) for the terminal and configures corresponding PRACH resources and random access preambles for each SSB / CSI-RS. Then, when the terminal determines that a beam is a new beam, it uses the PRACH resources corresponding to the new beam to send the corresponding random access preamble. After receiving it, the network device knows that the terminal has experienced a beam failure. The network device determines the new beam selected by the terminal based on the received PRACH information and sends a random access response on the new beam.
[0090] If the network device is not configured with the reference signal for NBI and the corresponding PRACH resources, that is, the terminal has no alternative beam to measure, or the L1-RSRP measurement values corresponding to all candidate beams are worse than the threshold configured by the network device; when these situations occur, the terminal will initiate the existing contention-based random access process to complete the reconnection with the network device based on the SSB signal quality measurement results in the cell. In addition, to further enhance the beam failure recovery mechanism in this situation, the terminal can carry a MAC CE (MAC Control Element) dedicated to indicating BFR information in the Msg3 or MsgA of the contention-based random access to indicate the network device that the random access process was triggered by a beam failure. At the same time, the BFR MAC CE can also carry information about the new beam selected by the UE.
[0091] ○ For the secondary cell (SCell),
[0092] □When a beam failure occurs in an SCell and the currently available uplink resources can meet the transmission of the BFR MAC CE, the terminal will report the beam failure information of the SCell based on the BFR MAC CE, including the secondary cell identification information and the indication information of the new beam.
[0093] □ If there are currently insufficient uplink resources to send a BFR MAC CE, the terminal can request uplink resources to send a BFR MAC CE by sending a Selective Repeat (SR).
[0094] If the terminal has no available uplink resources to transmit the BFR MAC CE and the network equipment does not provide SR configuration, the terminal triggers a random access procedure based on the R15 behavior to obtain uplink resources.
[0095] □If the new beam selection process on the secondary cell fails to select a beam that meets the threshold requirements configured by the system, the terminal reports the identification information of this secondary cell and a special status to indicate that no new beam that meets the threshold is found among the candidate beams configured by the network equipment for this secondary cell.
[0096] When multiple secondary cells execute their own beam failure recovery processes, it is possible that multiple secondary cells may simultaneously detect beam failure. In this case, the beam failure information of multiple secondary cells can be reported all at once through the same BFR MAC CE, thereby saving resource overhead and reducing latency. If beam failure occurs simultaneously in multiple secondary cells, but the currently available uplink resources cannot transmit the beam failure information of all secondary cells, the identifiers of the secondary cells experiencing beam failure can be reported to the network device via a truncated BFR MAC CE. When the network device receives the truncated MAC CE, it can determine which cells have experienced beam failure and that the UE does not have sufficient uplink resources to report the beam failure information, so it can allocate uplink resources to the terminal.
[0097] □BFR MAC CE reporting can be transmitted through the PUSCH (Physical Downlink Control Channel) in the primary cell or through the PUSCH in the secondary cell.
[0098] ●Network device response.
[0099] ○ For the primary cell (PCell) and the secondary primary cell (PSCell),
[0100] □After receiving the BFRQ information sent by a terminal, the network device knows that the terminal has experienced a beam failure and chooses to send PDCCH from a new beam. When the terminal receives the PDCCH sent by the network device on the new beam, it believes that it has correctly received the response information of the network device.
[0101] □ To monitor the network device's response to BFRQ, that is, the random access response, the terminal will start the ra-ResponseWindow and begin monitoring the PDCCH on the first PDCCH occasion after sending MSG1.
[0102] □If within the ra-ResponseWindow, the terminal detects the DCI (Downlink Control Information) sent to it by the network device on the new beam, it is considered that the beam recovery is successful.
[0103] If the terminal does not detect the DCI sent by the network device on the new beam within the ra-ResponseWindow, it can resend the BFRQ. This process can be repeated until the beam recovery process is successful or the number of BFRQ retransmissions exceeds the threshold specified by the network device.
[0104] ○ For the secondary cell (SCell),
[0105] Whether the network device has correctly received the MAC CE signaling can be determined through the existing PUSCH HARQ-related mechanisms. If the terminal receives an uplink grant for scheduling new data corresponding to the same HARQ process, it is considered that the previous transmission has been correctly received by the network device.
[0106] In the NTN system, satellite wireless communication relies primarily on direct signal transmission. The higher the satellite's orbital altitude, the greater the signal attenuation. If a terminal device communicating with the satellite is in an obstructed environment, such as when it's in a backpack or pocket, signal transmission is blocked and penetration loss is high, resulting in poor communication quality and even possible interruption. It's currently unclear how to improve signal transmission robustness in scenarios with poor communication quality.
[0107] Please refer to Figure 7, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method is executed by a terminal device and may include the following step 710.
[0108] Step 710: The terminal device starts a first timer and / or sends a first prompt message based on a first event, where the first event is an event related to the communication quality of the terminal device.
[0109] In some embodiments, the terminal device starts a first timer based on the first event.
[0110] In some embodiments, the terminal device issues a first prompt message based on the first event.
[0111] In some embodiments, the terminal device starts a first timer based on the first event and sends a first prompt message.
[0112] In some embodiments, if the first event occurs, it indicates that the communication quality of the terminal device is poor. Based on the occurrence of the first event, the terminal device starts a first timer and / or sends a first prompt message.
[0113] In some embodiments, the terminal device starts a first timer based on the first event and sends a first prompt message within the valid duration of the first timer.
[0114] In some embodiments, the terminal device sending the first prompt information includes: the terminal device sending the first prompt information to a higher layer. For example, the physical layer of the terminal device sends the first prompt information to the higher layer of the terminal device based on the first event.
[0115] In some embodiments, the terminal device sending the first prompt information includes: the terminal device sending the first prompt information to the network device. For example, the terminal device sends the first prompt information to the network device through MAC CE or RRC based on the first event.
[0116] In some embodiments, the first prompt message is used to alert the user to improve the communication quality of the terminal device. This application does not limit the form of the first prompt message. Optionally, the first prompt message is an indication message. Exemplarily, the first prompt message may be a MAC CE or RRC. Optionally, the first prompt message is an application layer message. Exemplarily, the first prompt message may be one or more of a ringtone, a vibration, and a text prompt. For example, the first prompt message may be a ringtone or a ringtone plus a vibration.
[0117] In some embodiments, after the terminal device sends the first prompt message, the user moves the terminal device to an open location, or assists in adjusting the position of the terminal device or the antenna angle to improve communication quality.
[0118] In some embodiments, the first event includes at least one of the following:
[0119] A first measurement result corresponding to the first reference signal is lower than a first threshold;
[0120] RLF;
[0121] Beam failure;
[0122] New beam selection;
[0123] Beam failure recovery request;
[0124] Conditional switching;
[0125] The first reference signal is not received;
[0126] PDCCH not received;
[0127] PBCH not received;
[0128] The paging channel is not received;
[0129] receiving first indication information, where the first indication information is used to determine a first event;
[0130] The first indication information is not received.
[0131] In some embodiments, the terminal device starts a first timer and / or sends a first prompt message based on the first measurement result corresponding to the first reference signal being lower than a first threshold.
[0132] In some embodiments, the first reference signal may be a reference signal dedicated to evaluating the communication quality of the terminal device, or may be a reference signal having other functions.
[0133] In some embodiments, the first reference signal includes at least one of: SSB, CSI-RS, and synchronization signal.
[0134] The CSI-RS is used to measure the downlink channel quality. The terminal device can determine the first measurement result based on the measurement result obtained by measuring the downlink channel quality using the CSI-RS.
[0135] In some embodiments, the terminal device determines the first measurement result based on a CQI (Channel Quality Indicator) obtained by measuring the CSI-RS. The terminal device may report the CSI for the network device to perform link adaptive adjustment. Exemplarily, the CQI obtained by measuring the CSI-RS is determined as the first measurement result.
[0136] SSB consists of synchronization signals and PBCH. The synchronization signals include PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal). That is, PSS, SSS, PBCH and DMRS (DeModulation Reference Signal) are received in four consecutive OFDM (Orthogonal Frequency Division Multiplexing) symbols and then form SSB, which is mainly used for downlink synchronization.
[0137] In some embodiments, the first measurement result is used to reflect the signal quality of the first reference signal received by the terminal device.
[0138] In some embodiments, the terminal device performs signal quality measurement on the received first reference signal to obtain a first measurement result.
[0139] In some embodiments, the measurement metric corresponding to the first measurement result includes at least one of the following: BLER, RSRP, RSRQ, and SINR of the hypothetical PDCCH.
[0140] In some embodiments, if the measurement metric corresponding to the first measurement result is the BLER of the hypothetical PDCCH, the terminal device determines an SINR value based on the BLER of the hypothetical PDCCH and uses the SINR value as the first threshold. The terminal device measures the SINR of the first reference signal to obtain the first measurement result.
[0141] The first threshold is a threshold used to measure the communication quality of the terminal device. In some embodiments, if the first measurement result is lower than the first threshold, it indicates that the signal quality of the first reference signal is poor, that is, the communication quality of the terminal device is poor.
[0142] In some embodiments, the first threshold is configured by the network device, or is predefined, or is preconfigured, or is determined by the terminal device itself.
[0143] In some embodiments, if the first threshold is determined by the terminal device itself, the terminal device reports the first threshold to the network device after determining the first threshold.
[0144] In some embodiments, the terminal device starts a first timer and / or issues a first prompt message based on RLF.
[0145] During the RLM process, the physical layer reports an IS / OOS indication to the upper layer each time. If the upper layer receives N310 consecutive OOS indications, it starts the radio link detection timer, indicating that a physical layer problem has been detected. While the radio link detection timer is running, if the upper layer receives N311 consecutive IS indications, it stops the radio link detection timer, indicating that the physical layer problem has been resolved. N310 and N311 are configured times. If the radio link detection timer expires, it indicates that an RLF event has occurred. Expiration of the radio link detection timer means that the upper layer has not received N311 consecutive IS indications while the radio link detection timer is running. The IS / OOS threshold is determined based on the BLER of the hypothetical PDCCH, and the IS / OOS threshold is the SINR value. In other words, an IS indication indicates that the terminal device's communication quality is good, an OOS indicates that the terminal device's communication quality is poor, and the occurrence of an RLF event indicates that the terminal device's communication quality has remained at a poor level during the infinite link detection timer.
[0146] In some embodiments, when one or more events in the BFR mechanism occur, the terminal device starts a first timer and / or issues a first prompt message. The one or more events in the BFR mechanism include at least one of the following: beam failure; new beam selection; beam failure recovery request.
[0147] In some embodiments, the terminal device starts a first timer and / or issues a first prompt message based on beam failure.
[0148] In some embodiments, beam failure includes at least one of the following: the terminal device's measurement result of CSI-RS is worse than a first threshold during the BFD process; the terminal device reports a BFI occurrence during the BFD process; the terminal device determines that a beam failure occurs during the BFD process.
[0149] In some embodiments, the terminal device starts a first timer and / or sends a first prompt message based on the new beam selection.
[0150] In some embodiments, the new beam selection includes at least one of the following: the measurement values corresponding to all candidate beams during the NBI process are worse than the threshold value configured by the network; the measurement values corresponding to all candidate beams during the NBI process are worse than the first threshold.
[0151] In some embodiments, the terminal device starts a first timer and / or issues a first prompt message based on the beam failure recovery request.
[0152] In some embodiments, the beam failure recovery request includes at least one of the following: during the BFRQ process, the SSB signal quality measurement result is worse than the first threshold; during the network device response process, the terminal device resends the BFRQ.
[0153] In some embodiments, the terminal device starts a first timer and / or issues a first prompt message based on conditional switching.
[0154] In conditional switching, the network device pre-configures the candidate target cell and switching command information to the terminal device in advance. When the switching conditions are met, the terminal device can autonomously execute the configuration in the switching command and directly initiate switching access to the target cell that meets the conditions.
[0155] In some embodiments, if communication between a terminal device and a network device is interrupted, the terminal device may be unable to receive signals or channels from the network device. Therefore, if one or more of the following situations occur, it can also be considered that the first event has occurred: failure to receive the first reference signal; failure to receive the PDCCH; failure to receive the PBCH; failure to receive the paging channel; or failure to receive the first indication information.
[0156] In some embodiments, the terminal device starts a first timer and / or sends a first prompt message based on failure to receive the first reference signal.
[0157] In some embodiments, the terminal device starts a first timer and / or issues a first prompt message based on not receiving the PDCCH.
[0158] In some embodiments, the terminal device starts a first timer and / or sends a first prompt message based on not receiving the PBCH.
[0159] In some embodiments, the terminal device starts a first timer and / or sends a first prompt message based on not receiving a paging channel.
[0160] In some embodiments, the terminal device starts a first timer and / or sends a first prompt message based on not receiving the first indication information, and the first indication information is used to determine the first event.
[0161] In some embodiments, the first indication information is used to indicate a first event, or the first indication information is used to configure the first event.
[0162] In some embodiments, the first indication information is used to indicate a first event, which means that the first indication information is used to indicate the occurrence of a first event, and after receiving the first indication information, the terminal device starts a first timer and / or sends a first prompt information.
[0163] In some embodiments, the first indication information is used to configure a first event, meaning that the first indication information is used to configure a terminal device to start a first timer and / or issue a first prompt message based on the first event. Exemplarily, the first indication information configures the activation of a first capability. For example, when the first indication information is configured as "alert on," the terminal device independently determines whether to activate the first timer and / or issue the first prompt message. Exemplarily, the first indication information configures the deactivation of the first capability. For example, when the first indication information is configured as "alert off," the terminal device does not activate the first timer and / or issue the first prompt message. Exemplarily, the first indication information configures which specific events are included in the first event. For example, when the first indication information configures the first event to include RLF, the terminal device starts the first timer and / or issues the first prompt message when RLF is determined, after a first duration has elapsed after RLF is determined, or before RLF is determined. Optionally, when the first indication information configures which specific events are included in the first event, the terminal device does not activate the first timer and / or issue the first prompt message for unconfigured events, or the terminal device independently determines whether to activate the first timer and / or issue the first prompt message.
[0164] In some embodiments, the network device does not send the first indication information, or the first indication information does not configure the first event, and the terminal device independently determines whether to start the first timer and / or issue the first prompt information. Exemplarily, the network device does not send the first indication information, or the first indication information does not configure the first event, for example, the first indication information does not configure "alert on", and the terminal device independently determines whether to start the first timer and / or issue the first prompt information.
[0165] It should be noted that the first capability in the embodiment of the present application refers to the ability of the terminal device to start a first timer and / or send a first prompt message. If the first capability appears in other embodiments of the present application, it should be understood in this way, and this application will not elaborate on it.
[0166] In some embodiments, the first indication information may be one or more pieces of information. For example, one piece of first indication information is used to configure the first event, and another piece of first indication information is used to indicate the first event.
[0167] In some embodiments, the first indication information is carried in at least one of the following signaling: DCI, RRC signaling, MAC CE, and system message.
[0168] In some embodiments, the first indication information is carried in at least one of the following signals or channels: PDCCH, PDSCH, PBCH, SSB, CSI-RS, PRS (Positioning Reference Signal).
[0169] In the technical solution provided by the embodiment of the present application, the terminal device determines whether to enable the first timer and / or whether to issue a first prompt message based on an event related to the communication quality of the terminal device. In the event that the communication quality of the terminal device is poor or a communication interruption occurs, the terminal device can, within the effective duration of the first timer, warn the user through the first prompt message to improve the communication quality of the terminal device, such as prompting the user to move the terminal device to an open location, or assisting in adjusting the position of the terminal device or the antenna angle, thereby improving the robustness of signal transmission, thereby improving the communication quality of the wireless signal and achieving the purpose of quickly restoring wireless communication.
[0170] In some embodiments, before step 710 , the method further includes the following step 720 (not shown in FIG. 7 ).
[0171] Step 720: The terminal device receives first configuration information sent by the network device, where the first configuration information is used to configure at least one of the following: a first timer, a start time of the first timer, an effective duration of the first timer, a first event, a first threshold, a first reference signal, a measurement metric corresponding to the first measurement result, and a first duration.
[0172] Accordingly, the network device sends first configuration information to the terminal device, where the first configuration information is used to configure the terminal device to start a first timer and / or issue a first prompt message based on a first event, where the first event is an event related to the communication quality of the terminal device.
[0173] In some embodiments, the first configuration information may be one or more pieces of configuration information.
[0174] In some embodiments, if there are multiple pieces of first configuration information, the contents configured in the multiple pieces of first configuration information may be the same or different. For example, one piece of first configuration information may be used to configure a first timer, and another piece of first configuration information may be used to configure a first event. For another example, two pieces of first configuration information may be used to configure both a first timer and a first event.
[0175] In some embodiments, the first configuration information is carried in at least one of the following signaling: DCI, RRC signaling, MAC CE, and system message.
[0176] In some embodiments, after the terminal device prompts the user to pay attention to the communication quality, the terminal device also needs to determine whether the wireless communication is restored. This application provides two embodiments for this.
[0177] Method 1: After the first timer expires, the terminal device determines whether wireless communication is restored
[0178] In some embodiments, after step 710 , the method further includes the following step 730 (not shown in FIG. 7 ).
[0179] Step 730: After the first timer expires, the terminal device starts a second timer.
[0180] In some embodiments, before step 730 , the method further includes the following step 740 (not shown in FIG. 7 ).
[0181] Step 740: The terminal device receives second configuration information sent by the network device, where the second configuration information is used to configure at least one of the following: a second timer, a start time of the second timer, and a valid duration of the second timer.
[0182] In some embodiments, the second configuration information may be one or more pieces of configuration information.
[0183] In some embodiments, if there are multiple pieces of second configuration information, the configuration contents of the multiple pieces of second configuration information may be the same or different. For example, one piece of second configuration information may be used to configure the second timer, and another piece of second configuration information may be used to configure the start time of the second timer and the validity period of the second timer. For another example, both pieces of second configuration information may be used to configure the second timer.
[0184] In some embodiments, the second configuration information is carried in at least one of the following signaling: DCI, RRC signaling, MAC CE, and system message.
[0185] In some embodiments, the first configuration information and the second configuration information may be the same configuration information, in which case the configuration information is used to configure at least one of the following: a first timer, a start time of the first timer, a valid duration of the first timer, a first event, a first threshold, a first reference signal, a measurement metric corresponding to the first measurement result, a first duration, a second timer, a start time of the second timer, and a valid duration of the second timer.
[0186] In some embodiments, within the valid duration of the first timer, the terminal device does not perform at least one of the following actions: downlink reception, downlink measurement, and uplink transmission.
[0187] In some embodiments, within the effective duration of the second timer, the terminal device performs at least one of the following actions: downlink reception, downlink measurement, and uplink transmission.
[0188] It should be noted that step 740 may be performed before or after step 710, and this application does not limit this. If the first configuration information and the second configuration information are the same configuration information, the terminal device performs the step of receiving the configuration information before step 710.
[0189] Exemplarily, a network device configures a first threshold, a first timer length, a second timer length, and a first reference signal, wherein the measurement metric corresponding to the first measurement result is the BLER of a hypothetical PDCCH. A terminal device measures the first reference signal to obtain a first measurement result. When the first measurement result is lower than the first threshold, the terminal device starts a first timer. During the execution of the first timer, the terminal device does not perform downlink reception, and / or does not perform downlink measurements, and / or does not perform uplink transmission. The terminal device may alert a user to improve wireless communication quality. For example, the terminal device's physical layer may send a first prompt message to a higher layer, or may alert / remind the user through vibration, ringtones, or text prompts, prompting the user to move the terminal device to an open area or adjust the terminal device's position or antenna angle to improve wireless signal communication quality. After the first timer expires, the terminal device starts a second timer. During the execution of the second timer, the terminal device may attempt downlink reception, and / or may attempt downlink measurements, and / or may attempt uplink transmission. In this way, the terminal device can also quickly restore wireless communication.
[0190] Through the above method, the terminal device prompts the user to improve the quality of wireless communication within the effective duration of the first timer. After the first timer expires, the terminal device starts the second timer. During the operation of the second timer, it attempts downlink reception, downlink measurement, and / or uplink transmission to determine whether the wireless communication of the terminal device is restored.
[0191] Method 2: The terminal device determines whether wireless communication is restored within the valid time of the first timer
[0192] In some embodiments, after the first timer expires, the terminal device does not start the second timer.
[0193] In other words, the method does not include the above-mentioned steps 730 and 740.
[0194] In some embodiments, within the effective duration of the first timer, the terminal device performs at least one of the following actions: downlink reception, downlink measurement, and uplink transmission.
[0195] In some embodiments, after sending the first prompt information, the terminal device performs at least one of the following actions: downlink reception, downlink measurement, and uplink transmission.
[0196] In some embodiments, compared with method one, the effective duration of the first timer in method two is longer.
[0197] Exemplarily, the network device configures a first threshold, an effective duration of a first timer, and a first reference signal, wherein the measurement metric corresponding to the first measurement result is the BLER of the hypothetical PDCCH. The terminal device measures the first reference signal to obtain a first measurement result, and when the first measurement result is lower than the first threshold, the terminal device starts the first timer. During the operation of the first timer, the terminal device can alert the user to improve the quality of wireless communication, for example, the physical layer of the terminal device sends a first prompt message to the upper layer, or alerts / reminds the user through vibration, ringtones or text prompts, so that the user can put the terminal device in an open place, or assist in adjusting the position of the terminal device or the antenna angle, etc., to improve the communication quality of the wireless signal. At the same time, after reserving sufficient warning time, the terminal device can attempt to perform downlink reception; and / or, the terminal device can attempt to perform downlink measurement; and / or, the terminal device can attempt to perform uplink transmission. In this way, the terminal device can achieve the purpose of quickly resuming wireless communication.
[0198] Through the above method, during the operation of the first timer, the terminal device prompts the user to pay attention to improving the quality of wireless communication, and attempts downlink reception, downlink measurement, and / or uplink transmission to determine whether the wireless communication of the terminal device is restored.
[0199] In some embodiments, step 710 includes the following three implementations.
[0200] Method 1: When the first event occurs, start the first timer and / or send the first prompt message
[0201] In some embodiments, when the first event occurs, starting a first timer and / or issuing a first prompt message includes at least one of the following:
[0202] When the first measurement result corresponding to the first reference signal is lower than a first threshold, starting a first timer and / or issuing a first prompt message;
[0203] When RLF is determined, starting a first timer and / or issuing a first prompt message;
[0204] When it is determined that the beam formation fails, starting a first timer and / or issuing a first prompt message;
[0205] When the condition for initiating conditional switching is met, starting a first timer and / or issuing a first prompt message;
[0206] When receiving the first indication information, starting a first timer and / or issuing a first prompt information, the first indication information is used to determine the first event;
[0207] When the target channel or signal is not received, starting a first timer and / or sending a first prompt message;
[0208] The target channel or signal includes at least one of the following: a first reference signal, a first PDCCH, a PBCH, a paging channel, and first indication information.
[0209] In one scenario, the terminal device independently determines whether to start the first timer and / or issue the first prompt message; or, the terminal device independently determines whether to start the first timer and / or issue the first prompt message based on the first indication information of the network device. Optionally, the first indication information is used to configure the first event.
[0210] Optionally, the terminal device independently determines whether to start the first timer and / or send the first prompt information, including at least one of the following:
[0211] When the first measurement result corresponding to the first reference signal is lower than the first threshold, the terminal device starts a first timer and / or sends a first prompt message;
[0212] When RLF is determined, the terminal device starts a first timer and / or issues a first prompt message;
[0213] When it is determined that the beam forming fails, the terminal device starts a first timer and / or issues a first prompt message;
[0214] When the condition for initiating conditional switching is met, the terminal device starts a first timer and / or sends a first prompt message;
[0215] When the target channel or signal is not received, the terminal device starts a first timer and / or sends a first prompt message.
[0216] In another case, the terminal device determines whether to start the first timer and / or send the first prompt information based on the instruction of the network device.
[0217] Optionally, when receiving the first indication information, the terminal device starts a first timer and / or sends a first prompt information, and the first indication information is used to determine the first event.
[0218] Through the above method, when the first event occurs, the terminal device prompts the user to improve the quality of wireless communication, so as to achieve the purpose of restoring wireless communication as soon as possible.
[0219] Method 2: After the first event occurs and the first time period has passed, start the first timer and / or send the first prompt message

[0275] Regarding the methods provided in the above embodiments of the present application, as examples rather than limitations, the present application provides the following embodiments in combination with different situations.
[0276] 1. Initial Access Process
[0277] The terminal device presets a first threshold. When the terminal device detects a synchronization signal but does not receive the PBCH, or when the terminal device's measurement result of the synchronization signal is lower than the first threshold, the terminal device starts a first timer and / or issues a first prompt message to remind the user to improve the quality of wireless communication. After reserving a sufficient warning time, the terminal device reattempts to receive the SSB.
[0278] The terminal device presets a first threshold or the network device configures the first threshold through the MIB. When the terminal device detects an SSB but does not receive a system message, or when the terminal device's measurement result of the SSB is lower than the first threshold, the terminal device starts a first timer and / or issues a first prompt message to remind the user to improve the quality of wireless communication. After reserving a sufficient warning time, the terminal device retries to receive the SSB.
[0279] 2. RLM Process
[0280] The terminal device presets the first threshold or the network device configures the first threshold. The network device configures "alert on (alert start)".
[0281] Before the physical layer of the terminal device reports an Out-of-System-of-Service (OOS) indication to the upper layer, or before the terminal device starts the radio link detection timer, or before the terminal device declares RLF, the terminal device starts a first timer. During the first timer, the terminal device reminds the user to improve the quality of wireless communication. After reserving sufficient warning time, the terminal device resumes the RLM process.
[0282] Alternatively, before the physical layer of the terminal device reports an OOS indication to a higher layer, or before the terminal device starts a radio link detection timer, or before the terminal device declares RLF, the terminal device starts a first timer. During the operation of the first timer, the terminal device reminds the user to improve the quality of wireless communication. After the first timer expires, the terminal device starts a second timer. During the operation of the second timer, the terminal device re-performs the RLM process.
[0283] In some embodiments, if the above-mentioned events still occur during the re-RLM process of the terminal device (the physical layer reports an OOS indication to the upper layer, or starts the wireless link detection timer, or declares RLF), the first timer will no longer be started and / or the first prompt message will no longer be issued.
[0284] 3. RRM Measurement
[0285] The terminal device presets the first threshold or the network device configures the first threshold. The network device configures "alert on (alert start)".
[0286] During the RRM measurement process, when the terminal device's measurement result of the measurement reference signal falls below a first threshold, the terminal device starts a first timer. During the first timer's operation, the terminal device reminds the user to improve the quality of wireless communication. After reserving a sufficient warning time, the terminal device re-performs the RRM measurement.
[0287] Alternatively, during the RRM measurement process, when the terminal device's measurement result of the measurement reference signal is lower than a first threshold, the terminal device starts a first timer. During the operation of the first timer, the terminal device reminds the user to improve the quality of wireless communication. After the first timer expires, the terminal device starts a second timer. During the operation of the second timer, the terminal device re-performs the RRM measurement.
[0288] In some embodiments, if the above event still occurs during the re-RRM measurement process of the terminal device (the measurement result of the measurement reference signal is lower than the first threshold), the first timer is no longer started and / or the first prompt information is no longer issued.
[0289] 4. BFR Mechanism
[0290] The terminal device presets the first threshold or the network device configures the first threshold. The network device configures "alert on (alert start)".
[0291] When one or more events in the BFR mechanism occur, the terminal device starts a first timer. During the first timer, the terminal device reminds the user to improve the quality of wireless communication. After reserving sufficient warning time, the terminal device resumes the BFR mechanism;
[0292] Alternatively, the terminal device starts a first timer, during which the terminal device reminds the user to improve the quality of wireless communication. After the first timer expires, the terminal device starts a second timer, during which the terminal device resumes the BFR mechanism.
[0293] In some embodiments, if the above event still occurs during the repeated BFR process of the terminal device, the alarm is no longer activated.
[0294] Among them, one or more events in the BFR mechanism include:
[0295] During the BFD process, the CSI-RS measurement result of the terminal device is worse than the first threshold;
[0296] During the BFD process, the terminal device reports a BFI.
[0297] During the BFD process, the terminal device determines that a beam failure has occurred;
[0298] During the NBI process, the measurement values corresponding to all candidate beams are worse than the threshold configured by the network;
[0299] During the NBI process, the measurement values corresponding to all candidate beams are worse than the first threshold;
[0300] During the BFRQ process, the SSB signal quality measurement result is worse than the first threshold;
[0301] During the network side response process, the terminal device resends the BFRQ.
