Description

Technical Field

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

[0002] When the signal environment between the terminal and the network device is very poor, the terminal cannot communicate with the network device. For example, in the non-terrestrial network (NTN) communication system, the satellite altitude can reach hundreds to tens of thousands of kilometers, and the uplink and downlink channel quality between the terminal and the satellite will be very poor. Generally speaking, the uplink and downlink channel quality can meet the needs of data transmission only when there is a direct path between the terminal device and the satellite. If there is no direct path between the terminal device and the satellite, the uplink and downlink channel quality will be very poor. For example, the terminal device is in an obstructed environment, which will result in no direct path between the terminal device and the satellite. In view of the above situation, when the network device finds that the uplink and downlink channel quality of the terminal device is very poor, how to ensure the accessibility between the terminal and the network is a problem that needs to be solved. Summary of the invention

[0005] In the above scheme, in response to satisfying the first condition, the terminal device starts detecting the first indication signal, and then performs a warning operation based on the detection result of the first indication signal. That is to say, the scheme of the embodiment of the present application sets a start condition for the terminal device to detect the first indication signal. The terminal device will start the detection of the first indication signal only when the first condition is met, and perform a warning operation based on the detection result of the first indication signal to remind the user that the current channel environment quality is very poor, and the environment in which the terminal device is located needs to be adjusted to improve the uplink or downlink channel quality of the terminal device and ensure the accessibility between the terminal device and the network device. If the first condition is not met, the terminal device will not start detecting the first indication signal, and will not receive the first indication signal.

[0052] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, third-generation systems (3G for short), long term evolution (LTE for short), fourth-generation systems (4G for short), 5G systems, new radio (NR for short), and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA for short) 5G system or a standalone (SA for short) 5G system. The solutions of the embodiments of the present application can also be applicable to various new communication systems in the future, such as 6G, 7G, etc.

[0053] The terminal device in the embodiments of the present application may refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal equipment (Terminal Equipment), wireless communication equipment, user agent or user device. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited to this.

[0054] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS for short) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the equipment that provides base station functions in the second-generation (2G) network includes a base transceiver station (BTS), the equipment that provides base station functions in the third-generation (3G) network includes a node B, and the equipment that provides base station functions in the fourth-generation (4G) network includes an evolved node B (eNB). In wireless local area networks (WLAN), the equipment that provides base station functions is an access point (AP), and the equipment that provides base station functions in NR is the next generation node base station (gNB) and the evolved node B (ng-eNB), where the gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0055] As described in the background technology, when a network device finds that the uplink or downlink channel quality of a terminal device is very poor (for example, the network device has been unable to page a terminal device for a period of time), the network device expects the user of the terminal device to be aware of the poor current channel environment and take relevant actions to improve the uplink or downlink channel quality of the terminal device, thereby ensuring the reachability between the terminal device and the network device.

[0056] Specifically, the network device may send a first indication signal, and after receiving the first indication signal, the terminal device may perform a warning operation. For example, the terminal device may remind the user that the current channel environment quality is very poor by vibration or ringing, so that the user can adjust the environment of the terminal device to improve the uplink or downlink channel quality of the terminal device and ensure the accessibility between the terminal device and the network device.

[0057] Among them, the first indication signal can be a public signal. For example, when the terminal device has not yet established a radio resource control (RRC) connection with the network device, the terminal device can usually only receive the public first indication signal sent by the network device, that is, all terminal devices in the cell will receive the first indication signal sent by the network device. In this scenario, all terminal devices in the cell are always detecting the first indication signal. After the network device sends the first indication signal, terminal devices with better channel environment quality will also receive the first indication signal, which will cause these terminal devices to perform unnecessary warning operations, affecting the user experience.

[0058] In view of this, an embodiment of the present application provides a communication method, in response to satisfying a first condition, a terminal device starts detecting a first indication signal, and then performs a warning operation based on the detection result of the first indication signal. That is to say, the scheme of the embodiment of the present application sets a start condition for the terminal device to detect the first indication signal, and the terminal device will only start the detection of the first indication signal when the first condition is met, and will not start detecting the first indication signal if the first condition is not met, and will not receive the first indication signal. Therefore, the above scheme can not only ensure the accessibility between the terminal device and the network device, but also help reduce the probability of false alarms.

[0059] In order to make the above-mentioned purposes, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0060] Reference Figure 1 , Figure 1 It is a signaling interaction diagram of a communication method in an embodiment of the present application. Figure 1 The method shown may include: S11 and S12. In this application, S in each step number represents a step. Figure 1 The method shown can be applied to a terminal device.

[0061] S11, in response to satisfying a first condition, starting to detect a first indication signal;

[0062] S12: Execute a warning operation based on the detection result of the first indication signal.

[0063] Specifically, the network device may send a first indication signal. The first indication signal may be used to trigger the terminal device to perform an alert operation. The alert operation may be used to alert or remind the user that the channel environment of the current terminal device is poor. For example, the alert operation may be vibration or ringing. For another example, the alert operation may be displaying graphic information for alerting or playing audio information for alerting.

[0064] The first indication signal may be a periodic downlink signal, or the first indication signal may be a non-periodic downlink signal, which is not limited in the embodiment of the present application.

[0065] More specifically, the first indication signal may be a downlink reference signal. For example, the first indication signal may be a synchronization signal (SS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), etc., but is not limited thereto.

[0066] It should be noted that the first indication signal may also be referred to as a warning signal, an early warning signal, a notification signal, etc., which is not limited in the embodiments of the present application.

[0067] In the solution of the embodiment of the present application, for the terminal device, the terminal device does not continuously detect the first indication signal, but starts to detect the first indication signal when the first condition is met.

[0068] That is, the terminal device determines whether the first condition is satisfied, and if it is determined that the first condition is satisfied, it starts detecting the first indication signal. Detecting the first indication signal may refer to receiving the first indication signal, or monitoring the first indication signal.

[0069] In the solution of the embodiment of the present application, the first condition may be a condition related to the channel environment quality. When the terminal device determines that the first condition is satisfied, it means that the terminal device determines that its own channel environment quality is poor.

[0070] In some embodiments, the first condition may be predefined by a protocol. In other embodiments, the first condition may be preconfigured by a network device.

[0071] Further, if the terminal device determines that the first condition is met, the terminal device may start detecting the first indication signal.

[0072] In a specific implementation, the network device may indicate the time domain position and frequency domain position of the first resource to the terminal device. The first resource refers to the transmission resource of the first indication signal. Exemplarily, the network device may indicate the time domain position and frequency domain position of the first resource through system information. For example, the first resource may be a periodic resource or a semi-persistent resource, and the first resource configuration may include: the period of the first resource, the starting time domain position, and the frequency domain position.

[0073] In one embodiment of the present application, different terminal devices detect the first indication signal on the same first resource. That is, all terminal devices in the cell detect the first indication signal on the same first resource.

[0074] In another embodiment of the present application, the network device can distinguish the terminal device receiving the first indication signal through different first resources, and different first resources correspond to different terminal devices. Among them, different first resources can refer to: first resources with different time domain positions but the same frequency domain positions; or first resources with the same time domain positions but different frequency domain positions; or first resources with different time domain positions and different frequency domain positions; or first resources with different code domains. Among them, the first resources with different code domains can be first resources with the same time domain position and the same frequency domain position, but different code domains; or first resources with different code domains can be first resources with the same time domain position, but different frequency domain positions and different code domains; or first resources with different code domains can be first resources with the same frequency domain position, but different time domain positions and different code domains; or first resources with different code domains can be first resources with different time domain positions, different frequency domain positions and different code domains. For example, the network device can send the first indication signal in a time division and / or frequency division manner. Correspondingly, the terminal device can detect the first indication signal on the first resource corresponding to itself. Adopting such a solution can also avoid the situation where all terminal devices in the cell receive the first indication signal, which is helpful to reduce the probability of false alarms.

[0075] In a specific implementation, the terminal device detects the first indication signal on the first resource corresponding to itself by default. Alternatively, the network device may configure the terminal device to detect the first indication signal on the first resource corresponding to itself. Specifically, before the terminal device starts detecting the first indication signal, the network device may send the fifth configuration information, and accordingly, the terminal device receives the fifth configuration information, and the fifth configuration information may be used to configure the terminal device to detect the first indication signal on the first resource corresponding to itself.

[0076] Exemplarily, the first resources corresponding to different terminal devices may be different. For example, after terminal device 1 starts detecting the first indication signal, it detects the first indication signal on first resource 1, and after terminal device 2 starts detecting the first indication signal, it detects the first indication signal on first resource 2, and resource 1 and resource 2 have different time domain positions and / or different frequency domain positions. Among them, the first resource corresponding to the terminal device may be determined according to the identifier of the terminal device. The network device may configure the terminal device to determine the location of the corresponding first resource according to its own identifier. For example, the network device may configure the terminal device to determine the first resource based on its own identifier through the fifth configuration information, and detect the first indication signal on the first resource. The terminal device performs a modulo calculation on its own identifier, and determines the location of the corresponding first resource according to the modulo result.

[0077] For example, the first resources corresponding to the terminal devices belonging to the same group are the same, and the first resources corresponding to the terminal devices belonging to different groups are different. For example, the terminal device group 1 corresponds to the first resource 3, and the terminal device group 2 corresponds to the first resource 4, and the first resource 3 is different from the first resource 4. The group to which the terminal device belongs can be determined based on the modulo result of the terminal device's identifier.

[0078] In some embodiments of the present application, when the first condition is met, the terminal device starts to detect the first indication signal on the first resource corresponding to itself. In other embodiments, the terminal device may not determine whether the first condition is met, and directly and continuously detect the first indication signal on the first resource corresponding to itself. In other words, each terminal device detects the first indication signal on the first resource corresponding to itself, and then performs a warning operation based on the detection result of the first indication signal.

[0079] In S12, for each terminal device, a warning operation is performed based on the detection result of the first indication signal.

[0080] In some embodiments, for each terminal device, if the first indication signal is detected, the warning operation is performed. In other words, the terminal device performs the warning operation as long as it receives the first indication signal.

[0081] In other embodiments, for each terminal device, based on detecting the first indication signal and being the device indicated by the first indication signal, an alert operation is performed. That is, after receiving the first indication signal, the terminal device further analyzes the first indication signal to determine whether it is the device indicated by the first indication signal. If it is determined that it is the device indicated by the first indication signal, an alert operation is performed; if it is determined that it is not the device indicated by the first indication signal, no alert operation is performed.

[0082] Specifically, the first indication signal may include multiple indication bits, and the indication bits correspond to the terminal devices one by one. The terminal device indicated by the first indication signal may be a device whose corresponding indication bit has a value of 1. After receiving the first indication signal, if the terminal device determines that the value of the indication bit corresponding to itself is 1, it determines that it is the device indicated by the first indication signal; if it determines that the value of the indication bit corresponding to itself is 0, it determines that it is not the device indicated by the first indication signal.

[0083] From above, Figure 1 In the scheme shown, the terminal device starts detecting the first indication signal based on the determination result that the first condition is met. If the first condition is not met, there is no need to detect the first indication signal, thereby reducing the probability of false alarms and helping to reduce the energy consumption of the terminal device.

[0084] Reference Figure 2 , Figure 2 It is a flow chart of the second communication method in the embodiment of the present application. Figure 2 The method shown can be applied to a terminal device, Figure 2 The method shown may include: S21 and S22.

[0085] S21, in response to a measurement result of the reference signal quality being less than or equal to a first threshold, starting detection of a first indication signal;

[0086] S22: Execute a warning operation based on the detection result of the first indication signal.

[0087] Specifically, the terminal device can measure the reference signal to obtain a measurement result of the reference signal quality. If the measurement result of the reference signal quality is less than or equal to the first threshold, the terminal device can start detecting the first indication signal. If the measurement result of the reference signal quality is greater than the first threshold, the terminal device does not start the detection of the first indication signal. Among them, the measurement result of the reference signal quality can be a reference signal received power (Reference Signal Receiving Power, RSRP), a reference signal received quality (Reference Signal Receiving Quality, RSRQ), a channel quality indicator (Channel Quality Indicator, CQI), a signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), etc., which is not limited in this embodiment.

[0088] Exemplarily, the first threshold value may be configured by the network device. Specifically, the network device may send the first configuration information, and correspondingly, the terminal device receives the first configuration information, wherein the first configuration information may be used to configure the first threshold value. For example, the first configuration information may be carried in the system information. That is, optionally, before S21, the network device may send the first configuration information to the terminal device to configure the first threshold value.

[0089] As another example, the first threshold may also be predefined by a protocol.

[0090] It should be noted that the reference signal used to measure the quality of the reference signal and the first indication signal are different downlink signals.

[0091] From above, Figure 2 In the illustrated solution, the terminal device determines whether to start the detection of the first indication signal based on the measurement result of the reference signal quality. If the measurement result is less than or equal to the first threshold, it determines that its own channel environment is poor and starts the detection of the first indication signal. Figure 2 For more details of the scheme shown, please refer to the above Figure 1 The relevant description will not be repeated here.

[0092] Reference Figure 3 , Figure 3 It is a flow chart of the third communication method in the embodiment of the present application. Figure 3 The method shown can be applied to a terminal device, Figure 3 The illustrated method may include S31 and S32.

[0093] S31, in response to being located within the coverage of the target beam, starting to detect a first indication signal;

[0094] S32: Execute a warning operation based on the detection result of the first indication signal.

[0095] In S31, the terminal device can identify the beam in which it is located, and determine whether the beam in which it is located is the target beam.

[0096] Specifically, for each terminal device, if it is determined that it is located within the coverage of the target beam, it starts detecting the first indication signal; if it is determined that it is not located within the coverage of the target beam, it does not start detecting the first indication signal.

[0097] In one example, before S31, the network device may send a second configuration information, and correspondingly, the terminal device receives the second configuration information. The second configuration information may be used to configure or indicate a target beam. In S31, the terminal device may measure all synchronization signal blocks (SSBs) and determine the SSB with the best measurement result. If the beam corresponding to the SSB with the best measurement result is the target beam indicated by the second configuration information, the terminal device may determine that it is within the coverage of the target beam.

[0098] In another example, the second configuration information can be used to configure the SSB index information corresponding to the target beam, and the terminal device can determine the target beam based on the SSB index information configured by the network device. The terminal device can measure all SSBs and determine the SSB with the best measurement result. If the SSB with the best measurement result is the SSB indicated by the second configuration information, the terminal device can determine that it is within the coverage of the target beam.

[0099] As a variation, the network device may send second configuration information to the terminal device, and the second configuration information may be used to configure the target range. In addition, the terminal device may be configured with a global navigation satellite system (GNSS), and the terminal device may obtain its own location information based on the GNSS, and determine whether it is within the target range based on the acquired location information. If the terminal device determines that it is within the target range, it starts detecting the first indication signal, and if the terminal device itself is not within the target range, it does not start detecting the first indication signal. The target range may be the coverage range of the above-mentioned target beam.

[0100] From above, Figure 3 In the illustrated solution, the terminal device determines whether to start the detection of the first indication signal based on its own location information. Figure 3 For more details of the scheme shown, please refer to the above Figure 1 The relevant description will not be repeated here.

[0101] Reference Figure 4 , Figure 4 It is a flow chart of the fourth communication method in the embodiment of the present application. Figure 4 The method shown can be applied to a terminal device such as Figure 4 As shown, Figure 4 The illustrated method may include S41 and S42.

[0102] S41: In response to not receiving paging information within a first time period or not being paged within a first time period, start detecting a first indication signal.

[0103] S42: Execute a warning operation based on the detection result of the first indication signal.

[0104] In S41, the terminal device may continuously detect paging information, and if no paging information is received within the first time period or the terminal device is not paged within the first time period, it starts detecting the first indication signal.

[0105] In a specific implementation, the duration of the first time period may be predefined by a protocol, or the duration of the first time period may be configured by a network device.

[0106] Exemplarily, the first time period may be a paging cycle. Alternatively, the first time period may be M consecutive paging cycles, where M is a positive integer greater than 1. The number of paging cycles contained in the first time period may be predefined by the protocol or may be configured by the network device. For example, before S41, the network device may send third configuration information. For example, the third configuration information may be carried in the system information. Correspondingly, the terminal device receives the third configuration information, and the third configuration information may be used to configure the value of M. Alternatively, the value of M may also be predefined by the protocol. Among them, the network device may determine the value of M according to the paging rate. In some embodiments of the present application, the paging information may be any one of the following: Paging Early Indication (PEI), paging downlink control information (DCI), and paging message (Paging Massage). Among them, PEI is used to schedule the terminal device to monitor the paging DCI within its associated paging occasion (PO). The paging DCI is the DCI sent by the network device in the PO, and the paging DCI can be used to schedule the terminal device to receive the paging message. The paging message includes the identifier of the terminal device to be paged by the network device.

[0107] In other embodiments of the present application, the paging information may also be other downlink information in the paging process, which is not limited in the embodiments of the present application.

[0108] The following takes the first time period as M consecutive paging cycles as an example. Figure 4 Some specific examples of the illustrated scheme are described.

[0109] Example 1: The network device is configured with a terminal device to detect PEI, and the terminal device determines whether to start detecting the first indication signal based on the detection result of the PEI.

[0110] Specifically, the terminal device detects the PEI, and if the terminal device does not detect the PEI within M consecutive paging cycles, the terminal device starts detecting the first indication signal. If the terminal device detects the PEI, there is no need to start detecting the first indication signal.

[0111] Example 2: The network device is not configured with the terminal device to detect PEI, and the terminal device determines whether to start detecting the first indication signal based on the detection result of the paging DCI.

[0112] Specifically, the terminal device detects the paging DCI, and if the terminal device does not detect the paging DCI within M consecutive paging cycles, the terminal device starts detecting the first indication signal. If the terminal device detects the paging DCI, there is no need to start detecting the first indication signal.

[0113] Example 3: The terminal device determines whether to start detecting the first indication signal based on the detection result of the paging message.

[0114] In the solution of Example 3, the network device may be configured with PEI detection or may not be configured with PEI detection, and this embodiment does not limit this.

[0115] Considering that the paging message is carried on the physical downlink share channel (PDSCH), the PSDCH transmission has high requirements on the channel quality. Even if the terminal device receives the PEI or the paging DCI, it may not receive the paging message, and the channel environment where the terminal device is located cannot complete the paging. For this reason, if the terminal device does not detect the paging message within M consecutive paging cycles, the terminal device starts detecting the first indication signal. If the terminal device detects the paging message, there is no need to start the detection of the first indication signal.

[0116] More specifically, in the solution of Example 3, as long as the terminal device does not detect a paging message within M consecutive paging cycles, the terminal device starts detecting the first indication signal. Once the terminal device detects a paging message, no matter which terminal device or terminal devices the detected paging message is paged to, the terminal device will not start detecting the first indication signal.

[0117] Example 4: The terminal device determines whether to start detecting the first indication signal based on the paging situation.

[0118] Specifically, if the terminal device is not paged within M consecutive paging cycles, the terminal device starts detecting the first indication signal. If the terminal device is paged, there is no need to start detecting the first indication signal.

[0119] The terminal device being paged may refer to the terminal receiving a paging message for paging itself, that is, the paging message received by the terminal device includes its own identifier.

[0120] In the solution of Example 4, the network device may be configured with PEI detection or may not be configured with PEI detection, and this embodiment does not limit this.

[0121] From above, Figure 4 In the illustrated solution, the terminal device determines whether to start the detection of the first indication signal based on the reception of the paging information. Figure 4For more details of the scheme shown, please refer to the above Figure 1 The relevant description will not be repeated here.

[0122] Reference Figure 5 , Figure 5 It is a flow chart of the fifth communication method in the embodiment of the present application. Figure 5 The method shown can be applied to a terminal device such as Figure 5 As shown, Figure 5 The illustrated method includes S51 and S52.

[0123] S51, in response to a first timer timing out, starting to detect a first indication signal, wherein a restart condition of the first timer is receiving a paging message or being paged;

[0124] S52: Execute a warning operation based on the detection result of the first indication signal.

[0125] exist Figure 5 In the illustrated solution, the terminal device may be configured with a first timer, and the restart condition of the first timer is: receiving a paging message or the terminal device is paged. That is, whenever the terminal device receives a paging message or is paged, the first timer is reset to zero and restarts.

[0126] The duration of the first timer may be predefined by a protocol. Alternatively, the duration of the first timer may be configured by a network device. Specifically, before S51, the network device may send fourth configuration information, and correspondingly, the terminal device receives the fourth configuration information, wherein the fourth configuration information may be used to configure the duration of the first timer. Exemplarily, the fourth configuration information may be carried in system information. More specifically, the network device may determine the duration of the first timer based on a paging rate.

[0127] In S51, the terminal device may determine whether to start detecting the first indication signal based on whether the first timer has timed out. Once the first timer has timed out, the terminal device starts detecting the first indication signal. If the first timer has not timed out, the terminal device does not start detecting the first indication signal.

[0128] Below Figure 5 Some specific examples of the illustrated scheme are described.

[0129] Example a: The network device is configured with a terminal device to detect PEI, and based on the terminal device detecting PEI, the first timer is restarted.

[0130] Specifically, the terminal device detects the PEI, and once the PEI is detected, the first timer is restarted. After the first timer is started, if the first timer times out, the terminal device starts detecting the first indication signal.

[0131] Example b: The network device is not configured with the terminal device to detect PEI, and based on the terminal device receiving the paging DCI, the first timer is restarted.

[0132] Specifically, the terminal device detects the paging DCI, and once the paging DCI is detected, the first timer is restarted. After the first timer is started, if the first timer times out, the terminal device starts detecting the first indication signal.

[0133] Example c: based on the terminal device detecting a paging message, the first timer is restarted.

[0134] Specifically, the terminal device detects a paging message, and once the paging message is detected, the first timer will be restarted regardless of whether the detected paging message is used to paging itself. After the first timer is started, if the first timer times out, the terminal device starts detecting the first indication signal.

[0135] In the solution of example c, the network device may be configured with PEI detection or may not be configured with PEI detection, and this embodiment does not limit this.

[0136] Example d: Based on the terminal device being paged, the first timer is restarted.

[0137] Specifically, after receiving the paging message, the terminal device parses the paging message to determine whether it is the terminal device to be paged by the paging message (for example, determine whether the paging message contains its own identifier). Once the terminal device determines that it is the device to be paged by the paging message, it restarts the first timer. After the first timer is started, if the first timer times out, the terminal device starts detecting the first indication signal.

[0138] In the solution of example d, the network device may be configured with PEI detection or may not be configured with PEI detection, and this embodiment does not limit this.

[0139] From above, Figure 5 In the illustrated solution, the terminal device determines whether to start the detection of the first indication signal based on whether the first timer has timed out. Figure 5 For more details of the scheme shown, please refer to the above Figure 1 and Figure 4 The relevant description will not be repeated here.

[0140] Reference Figure 6 , Figure 6 It is a flow chart of the sixth communication method in the embodiment of the present application. Figure 6 The method shown can be applied to a terminal device such as Figure 6 As shown, Figure 6 The methods shown include:

[0141] S61, in response to receiving a higher layer signaling for activating first indication signal detection, starting detection of a first indication signal;

[0142] S62: Execute a warning operation based on the detection result of the first indication signal.

[0143] Specifically, the network device may send a high-layer signaling for activating the first indication signal detection. For the terminal device, if the high-layer signaling for activating the first indication signal detection is received, the detection of the first indication signal is started. If the high-layer signaling for activating the first indication signal detection is not received, the detection of the first indication signal is not started.

[0144] Exemplarily, the higher-layer signaling for activating the first indication signal detection may be carried in a system message.

[0145] Optionally, in the solution of the embodiment of the present application, the network device may send a high-layer signaling for deactivating the detection of the first indication signal to the terminal device. In response to receiving the high-layer signaling for deactivating the detection of the first indication signal, the terminal device may stop detecting the first indication signal. That is, if the high-layer signaling for deactivating the detection of the first indication signal is received, the terminal device stops detecting the first indication signal.

[0146] Exemplarily, a new activation indication field may be introduced into the system message. If the value of the activation indication field is 1, it indicates that the first indication signal detection is activated. If the value of the activation indication field is 0, it indicates that the first indication signal detection is deactivated.

[0147] From above, Figure 6 In the illustrated solution, the terminal device starts detecting the first indication signal based on the activation indication of the network device. Figure 6 For more details of the scheme shown, please refer to the above Figure 1 The relevant description will not be repeated here.

[0148] Reference Figure 7 , Figure 7 It is a flow chart of the seventh communication method in the embodiment of the present application. Figure 7 The method shown can be applied to a terminal device such as Figure 7 As shown, Figure 7 The methods shown include:

[0149] S71, in response to receiving a high-layer signaling for activating first indication signal detection, starting to determine whether a first condition is satisfied;

[0150] S72, in response to satisfying the first condition, starting to detect a first indication signal;

[0151] S73, performing a warning operation based on the detection result of the first indication signal.

[0152] Specifically, the network device may send a high-level signaling for activating the first indication signal detection. For the terminal device, if the high-level signaling for activating the first indication signal detection is received, that is, the network device indicates to activate the first indication signal detection, the terminal device starts to determine whether the first condition is met. If the high-level signaling for activating the first indication signal detection is not received, that is, the network device does not activate the first indication signal detection, the terminal device does not determine whether the first condition is met. For the specific content of the first condition, please refer to the above about Figures 1 to 5 The relevant description will not be repeated here.

[0153] Further, after starting to determine whether the first condition is met, the terminal device starts detecting the first indication signal once it determines that the first condition is met.

[0154] Optionally, the network device may also send a high-layer signaling for deactivating the first indication signal detection to the terminal device. In response to receiving the high-layer signaling for deactivating the first indication signal detection, the terminal device may stop determining whether the first condition is met.

[0155] From above, in Figure 7 In the illustrated solution, the terminal device starts the determination of the first condition based on the activation indication of the network device, and starts the detection of the first indication signal based on the determination result of the first condition. Figure 7 For more information about the scheme shown, please refer to the above Figures 1 to 6 The relevant description will not be repeated here.

[0156] Reference Figure 8 , Figure 8 It is a flow chart of the eighth communication method in the embodiment of the present application. Figure 8 The method shown can be applied to a terminal device, Figure 8 The methods shown include:

[0157] S81, in response to satisfying a first condition, starting to detect a first indication signal;

[0158] S82: In response to not detecting the first indication signal within the second time period, executing a warning operation.

[0159] The start time of the second time period is the time when the first condition is satisfied. Alternatively, the start time of the second time period is the start time of the first indication signal detection.

[0160] Specifically, after starting to detect the first indication signal, if the terminal device still fails to detect the first indication signal within the second time period, a warning operation is performed.

[0161] Exemplarily, the first indication signal may be a periodic downlink signal, and the second time period may be a period of K consecutive first indication signals, where K is a positive integer greater than 1.

[0162] As another example, the second time period may be L consecutive paging cycles, where L is a positive integer greater than 1.

[0163] In a specific implementation, the duration of the second time period may be configured by the network device. For example, the values ​​of K and L may be configured by the network device. Alternatively, the duration of the second time period may be predefined by a protocol. For example, the values ​​of K and L may be predefined by a protocol.

[0164] As a variation, in response to the first condition being met or the first indication signal being detected, the second timer is started. In response to the second timer timing out, an alert operation is performed. If the second timer has not timed out and the terminal device detects the first indication signal, the second timer is stopped and reset to zero. The duration of the second timer may be configured by the network device, or may be predefined by the protocol.

[0165] Specifically, when the terminal device determines that the first condition is satisfied or starts detecting the first indication signal, the second timer may be started. If the first indication signal is detected before the second timer times out, the terminal device performs an alert operation, and the second timer stops and returns to zero. If the second timer times out, the terminal device performs an alert operation.

[0166] From above, Figure 8 In the illustrated solution, after starting to detect the first indication signal, if the terminal device still fails to detect the first indication signal within a period of time, it means that the channel environment quality is so poor that the first indication signal cannot be transmitted normally. At this time, a warning operation is performed to remind the user to adjust the environment of the terminal device.
