The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment.

[0048] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0049] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0050] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0051] As an example and not a limitation, in an embodiment of the present application, the network device may have a mobile feature, for example, the network device may be a mobile device. In some embodiments of the present application, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of the present application, the network device may also be a base station set up in a location such as land or water.

[0052] 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 used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0053] For example, Figure 1A is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 1A, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or also referred to as a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices located within the coverage area.

[0054] Figure 1A exemplarily shows a network device and two terminal devices. In some embodiments of the present application, the communication system 100 may include multiple network devices and each network device may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0055] For example, FIG1B is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1B , a terminal device 1101 and a satellite 1102 are included, and wireless communication can be performed between the terminal device 1101 and the satellite 1102. The network formed between the terminal device 1101 and the satellite 1102 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1B , the satellite 1102 can have the function of a base station, and the terminal device 1101 and the satellite 1102 can communicate directly. In the system architecture, the satellite 1102 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0056] For example, FIG1C is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1C , it includes a terminal device 1201, a satellite 1202, and a base station 1203. Wireless communication can be performed between the terminal device 1201 and the satellite 1202, and communication can be performed between the satellite 1202 and the base station 1203. The network formed between the terminal device 1201, the satellite 1202, and the base station 1203 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1C , the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be transferred through the satellite 1202. In this system architecture, the base station 1203 can be referred to as a network device. In some embodiments of the present application, a plurality of network devices 1203 may be included in the communication system, and each network device 1203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0057] It should be noted that Figures 1A-1C are only examples of the system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems, such as 5G communication systems, LTE communication systems, etc., and the embodiment of this application does not make specific limitations on this.

[0058] In some embodiments of the present application, the wireless communication system shown in Figures 1A-1C may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but the embodiments of the present application are not limited to this.

[0059] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1A as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0060] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0061] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0062] The “configuration” in the embodiment of the present application may include configuration through at least one of system messages, radio resource control (RRC) signaling and media access control element (MAC CE).

[0063] In some embodiments of the present application, "predefined" or "preset" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). This application does not limit the specific implementation method. For example, predefined may refer to information defined in a protocol.

[0064] In some embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0065] In some communication systems (such as satellite communication systems), the terminal device needs to point the antenna towards the sky so that the receiver can obtain good signal quality or a good signal-to-noise ratio. However, in some cases, the reception condition of the terminal device's receiver may not be good. For example, when the user places the terminal device in an inner pocket, or when the user is moving to an area where the sky cannot be seen (such as a tunnel or inside a building), the communication quality of the terminal device will drop sharply. The decline in communication quality will cause serious problems. For example, if the terminal device has an important incoming call at this time, the terminal device will most likely miss the call.

[0066] To address the above issues, the following detailed examples illustrate embodiments of the present application. Embodiments of the present application can be applied to any of the aforementioned communication systems. For example, embodiments of the present application can be applied to communications in licensed or unlicensed frequency bands in NR.

[0067] FIG2 is a flow chart of a wireless communication method provided by one embodiment of the present application. The method of FIG2 can be executed by a first terminal device. For example, the first terminal device can be a terminal device supporting NTN communication (such as satellite communication).

[0068] 2 , in step S210 , if a first condition is met, the first terminal device triggers a first signal.

[0069] In some implementations, the first signal may be sent from a physical layer of the first terminal device to an upper layer of the physical layer.

[0070] In some implementations, the first signal is an alert signal.

[0071] In some implementations, the first signal is associated with a paging failure of the first terminal device. For example, the first signal is triggered when a paging failure of the first terminal device occurs. In another example, the first signal is used to indicate a paging failure of the first terminal device.

[0072] In some implementations, the first signal is used to indicate that the location of the first terminal device is not conducive to signal reception by the network device. Alternatively, the first signal is used to instruct a user of the terminal device to move to a location that is conducive to signal reception by the network device.

[0073] Taking satellite communications as an example, the first signal can be used to notify the user of the first terminal device (e.g., via a user interface of the first terminal device) that the first terminal device may be in a location or area with poor satellite signal reception conditions, such as when the first terminal device is in a pocket or under a roof that shields satellite signals. Based on the first signal, the user of the first terminal device can move to a location or area suitable for receiving satellite signals.

[0074] In some implementations, the first signal is used to trigger the first terminal device to initiate a random access process, namely, a random access channel (RACH) process.

[0075] In some implementations, the first condition is associated with a detection failure of the first channel.The first channel may be used to schedule transmission of paging information of the first terminal device.

[0076] In some implementations, the first channel may be transmitted at a time corresponding to a first paging occasion (PO). Accordingly, the terminal device may detect the first channel in the first paging occasion.

[0077] In some implementations, the first channel may be, for example, a physical downlink control channel (PDCCH). The PDCCH may be used to schedule a PDSCH, in which the paging information of the first terminal device is carried.

[0078] In some implementations, the first condition may include a detection failure of the first channel. That is, if the detection of the first channel fails, the first terminal device triggers the first signal.

[0079] Taking Figure 3 as an example, the network device can transmit PDCCH in PO, and the PDCCH is used to schedule the transmission of paging information of the first terminal device. Accordingly, the first terminal device can detect PDCCH in the PO. If the detection of the PDCCH fails, the physical layer of the first terminal device sends an alarm signal to the higher layer. From the perspective of the network device (such as a base station), the failure to detect PDCCH may mean that the network device sent PDCCH in PO, but the first terminal device did not receive the PDCCH. From the perspective of the first terminal device, the failure to detect PDCCH may mean that: the first terminal device detects PDCCH (that is, the first terminal device performs PDCCH monitoring), but fails to detect PDCCH.

[0080] In some implementations, the first condition may include the number of failed detections on the first channel reaching a first threshold. That is, if the number of failed detections on the first channel reaches the first threshold, the first terminal device triggers the first signal. This first threshold may be determined based on network device configuration information, pre-configured information, or autonomously implemented by the first terminal device. By setting the first threshold, frequent interruptions of the first signal to the first terminal device can be avoided, thereby improving the user experience.

[0081] Take the value of the first threshold as 2 as an example. Referring to Figure 4, the network device can transmit PDCCH in PO1 and PO2 respectively, and the PDCCH is used to schedule the transmission of paging information of the first terminal device. Accordingly, the first terminal device can detect PDCCH at PO1. If the PDCCH detection fails, the value of the counter of the first terminal device changes from 0 to 1. Then, the first terminal device can detect PDCCH at PO2. If the PDCCH detection fails, the value of the counter of the first terminal device changes from 1 to 2. Since the value of the counter reaches the first threshold at this time, the physical layer of the first terminal device sends an alarm signal to the upper layer. Alternatively, the initial value of the counter can also be set to 2. If the PDCCH detection in PO1 fails, the counter is reduced by 1; if the PDCCH detection in PO2 fails, the counter is reduced by 1 again. When the value of the counter is 0, the physical layer of the first terminal device sends an alarm signal to the upper layer.

[0082] In some implementations, the first condition is associated with a reception failure of a second channel, where the second channel is used to transmit paging information of the first terminal device.

[0083] In some implementations, the second channel is a physical downlink shared channel (PDSCH). The PDSCH may be used to carry paging information for the first terminal device. The PDSCH may be scheduled based on a PDCCH, and the terminal device may first detect the PDCCH before receiving the PDSCH.

[0084] In some implementations, the first condition may include a reception failure of the second channel. That is, if the reception of the second channel fails, the first terminal device triggers the first signal.

[0085] Taking Figure 5 as an example, the network device can transmit a PDCCH in the PO, which is used to schedule the transmission of paging information for the first terminal device. Accordingly, the first terminal device can detect the PDCCH in the PO and receive the PDSCH based on the detected PDCCH. If the reception of the PDSCH fails, the physical layer of the first terminal device sends an alarm signal to the higher layer.

[0086] In some implementations, the first condition may include the number of reception failures on the second channel reaching a second threshold. That is, if the number of reception failures on the second channel reaches the second threshold, the first terminal device triggers the first signal. This second threshold may be determined based on network device configuration information, pre-configured information, or autonomously implemented by the first terminal device. By setting the second threshold, frequent interruptions of the first signal to the first terminal device can be avoided, thereby improving the user experience.

[0087] Take the value of the second threshold as 2 as an example for explanation. Referring to Figure 6, the network device can transmit PDCCH in PO1 and PO2 respectively, and the PDCCH is used to schedule the transmission of paging information of the first terminal device. Accordingly, the first terminal device can detect PDCCH in PO1 and receive PDSCH based on the detected PDCCH. If PDSCH reception fails, the value of the counter of the first terminal device changes from 0 to 1. Then, the first terminal device can detect PDCCH in PO2 and receive PDSCH based on the detected PDCCH. If PDSCH reception fails, the value of the counter of the first terminal device changes from 1 to 2. Since the value of the counter reaches the second threshold at this time, the physical layer of the first terminal device sends an alarm signal to the upper layer. Alternatively, the initial value of the counter can also be set to 2. If the PDSCH scheduled by the PDCCH in PO1 fails to be received, the counter is decremented by 1; if the PDSCH scheduled by the PDCCH in PO2 fails to be received, the counter is decremented by 1 again. When the value of the counter is 0, the physical layer of the first terminal device sends an alarm signal to the upper layer.

[0088] In some implementations, the first condition may be associated with the number of detection failures of the first channel (such as PDCCH) and the number of reception failures of the second channel (such as PDSCH). For example, the first condition may include that the combined number of detection failures of the first channel and the reception failures of the second channel reaches threshold A. That is, if the combined number of detection failures of the first channel and the reception failures of the second channel reaches threshold A, the first terminal device triggers the first signal. Exemplarily, if the first terminal device does not detect PDCCH in PO1, the value of the counter changes from 0 to 1; then, if the terminal device detects PDCCH in PO2, but fails to successfully receive PDSCH in the PDSCH scheduled by the PDCCH, the value of the counter changes from 1 to 2. This process repeats until the counter reaches threshold A.

[0089] In some implementations, the first condition is associated with the reception quality of the second signal. The second signal may be, for example, a reference signal of some type or types. The second signal may include, for example, a synchronization signal block (SSB) and / or a channel state information reference signal (CSI-RS). Taking the second signal as the first CSI-RS as an example, the first CSI-RS includes one or more of the following: a CSI-RS for wireless link monitoring; a CSI-RS for beam failure detection; a tracking reference signal (TRS); a CSI-RS dedicated to triggering the first signal (such as a CSI-RS dedicated to triggering an alarm signal).

[0090] In some implementations, the reception quality of the second signal is determined based on a reference signal receiving power (RSRP) and / or a signal to noise ratio (SNR) of the second signal.

[0091] In some implementations, the first condition includes a reception quality of the second signal being less than or equal to a third threshold.

[0092] In some implementations, to avoid overly frequent triggering of the first signal or to avoid false triggering of the first signal, the first condition may include the number of times the reception quality of the second signal is less than or equal to a third threshold reaching a first threshold. That is, when the number of times the reception quality of the second signal is less than or equal to the third threshold reaches the first threshold, the first terminal device triggers the first signal. The number of times the reception quality of the second signal is less than or equal to the third threshold may be counted based on a counter.

[0093] In some implementations, the number of times the reception quality of the second signal is less than or equal to the third threshold reaches the first threshold may include: the number of times the reception quality of the second signal is continuously less than or equal to the third threshold reaches the first threshold. Taking the second signal as a reference signal that appears periodically as an example, when the reference signal appears for the first time, if the first terminal device measures the signal quality of the reference signal to be lower than the third threshold, the counter value changes from 0 to 1; when the reference signal appears for the second time, if the first terminal device measures the signal quality threshold of the reference signal to be lower than the third threshold, the counter value changes from 1 to 2; when the reference signal appears for the third time, if the first terminal device measures the signal quality of the reference signal to be higher than the third threshold, the counter is cleared at this time. That is, the first terminal device will trigger the first signal only when the signal quality of the reference signal is continuously lower than the third threshold.

[0094] In some implementations, the number of times the reception quality of the second signal is less than or equal to the third threshold reaches the first threshold may include: the number of times the reception quality of the second signal is less than or equal to the third threshold within the first time window reaches the first threshold. Taking the second signal as a reference signal that appears periodically as an example, when the reference signal appears for the first time, if the first terminal device measures the signal quality of the reference signal to be lower than the third threshold, the counter value changes from 0 to 1, and a timer is started at this time, and the timing duration of the timer represents the first time window; when the reference signal appears for the second time, if the first terminal device measures the signal quality of the reference signal to be lower than the third threshold, the counter value changes from 1 to 2; when the reference signal appears for the third time, if the first terminal device measures the signal quality of the reference signal to be higher than the third threshold, the counter value remains unchanged; when the reference signal appears for the fourth time, if the first terminal device measures the signal quality of the reference signal to be lower than the third threshold, but the timer has timed out at this time, the counter is cleared.

[0095] In some implementations, the second signal is a reference signal corresponding to the beam, and the number of times the reception quality of the second signal is less than or equal to the third threshold reaches the first threshold may include: the number of times the reception quality of the reference signal corresponding to a beam direction is less than or equal to the third threshold reaches the first threshold. In other words, if the number of times the reception quality of the reference signal corresponding to a beam direction is less than or equal to the third threshold reaches the first threshold, the first terminal device triggers the first signal.

[0096] In some implementations, the second signal is a reference signal corresponding to the beam (or beam direction), and the number of times the reception quality of the second signal is less than or equal to the third threshold reaches the first threshold may include: the number of times the reception quality of the reference signal corresponding to each beam is less than or equal to the third threshold reaches the first threshold. That is, if the number of times the reception quality of the reference signal corresponding to a certain beam direction is less than or equal to the third threshold does not reach the first threshold, the first terminal device does not trigger the first signal, because in this case, the first terminal device can receive the paging information by changing the beam direction. The correspondence between the beam and the reference signal may refer to the correspondence or correlation between the beam (or beam direction) and the index corresponding to the reference signal. Taking the downlink reference signal as an example, each index of the downlink reference signal may represent a beam (or beam direction). Exemplarily, SSB index 1 may represent beam 1, and SSB index 2 may represent beam 2. Alternatively, CSI-RS resource index 1 may represent beam 1, and CSI-RS resource index 2 may represent beam 2.

[0097] FIG7 is a flow chart illustrating a wireless communication method according to another embodiment of the present application. The method in FIG7 is described from the perspective of interaction between a first terminal device and a network device. For example, the first terminal device may be a terminal device supporting NTN communication (e.g., satellite communication). The network device may be a base station in the NTN network, such as a satellite.

[0098] 7 , in step S710 , a first terminal device detects or receives a first signal sent by a network device.

[0099] In some implementations, the first signal is an alert signal.

[0100] In some implementations, the first signal is associated with a paging failure of the first terminal device. For example, the first signal is triggered when a paging failure of the first terminal device occurs. In another example, the first signal is used to indicate a paging failure of the first terminal device.

[0101] In some implementations, the first signal is used to trigger the first terminal device to initiate a random access process, namely, a RACH process, to attempt to connect to a cell or a network device through the random access process.

[0102] In some implementations, if the first terminal device does not detect or receive the first signal, it may indicate that the first terminal device has not missed the paging message sent by the network device. Further, in some implementations, the first terminal device may continue to monitor for paging messages in subsequent paging occasions configured for the first terminal device.

[0103] In some implementations, the first signal is used to indicate that the location of the first terminal device is not conducive to signal reception by the network device. Alternatively, the first signal is used to instruct a user of the terminal device to move to a location that is conducive to signal reception by the network device.

[0104] Taking satellite communications as an example, the first signal can be used to notify the user of the first terminal device (e.g., via a user interface of the first terminal device) that the first terminal device may be in a location or area with poor satellite signal reception conditions, such as when the first terminal device is in a pocket or under a roof that shields satellite signals. Based on the first signal, the user of the first terminal device can move to a location or area suitable for receiving satellite signals.

[0105] In some implementations, the first signal is used to trigger the first terminal device to send a target signal.

[0106] In some implementations, the target signal may be sent from the physical layer of the first terminal device to an upper layer of the physical layer.

[0107] In some implementations, the target signal is an alert signal.

[0108] In some implementations, the target signal is associated with a paging failure of the first terminal device. For example, the target signal is triggered when a paging failure of the first terminal device occurs. For another example, the target signal is used to indicate a paging failure of the first terminal device.

[0109] In some implementations, the target signal is used to indicate that the location of the first terminal device is not conducive to signal reception by the network device. Alternatively, the target signal is used to instruct the user of the terminal device to move to a location that is conducive to signal reception by the network device.

[0110] Taking satellite communications as an example, the target signal can be used to notify the user of the first terminal device (e.g., via a user interface of the first terminal device) that the first terminal device may be in a location or area with poor satellite signal reception conditions, such as when the first terminal device is in a pocket or under a roof that shields satellite signals. Based on the target signal, the user of the first terminal device can move to a location or area suitable for receiving satellite signals.

[0111] In some implementations, the first signal is transmitted via a first transmission opportunity, which is one of one or more transmission opportunities configured for the first signal. For example, if the first signal is an alarm signal, one or more alarm occasions (AO) can be configured for the first terminal device.

[0112] In some implementations, the one or more transmission opportunities of the first signal are configured based on system information and / or RRC signaling. The RRC signaling may be, for example, terminal device-specific RRC signaling.

[0113] In some implementations, the first transmission opportunity is later than the first channel in the time domain; wherein the first channel is used to schedule the transmission of paging information of the first terminal device, and the detection of the first channel fails. The first channel may be, for example, a PDCCH. The PDCCH is used to schedule the PDSCH, and the PDSCH is used to carry the paging information of the first terminal device. That is, after the first channel detection fails, the first terminal device may start to receive the first signal at the transmission opportunity of the first signal, and receive the first signal at the above-mentioned first transmission opportunity. Taking the first signal as an alarm signal as an example, as shown in Figure 8, if the first terminal device fails to detect the PDCCH at PO, it may continue to detect or receive the alarm signal at the configured alarm opportunity. If the alarm signal is detected or received, the first terminal device may be triggered to perform the RACH process.

[0114] In some implementations, the first transmission opportunity is later in the time domain than the first channel; the first channel is used to transmit paging information for the first terminal device, and reception of the first channel fails. The first channel may be, for example, a PDSCH. The PDSCH is used to carry the paging information for the first terminal device. In other words, after the first channel detection fails, the first terminal device may begin receiving the first signal at the transmission opportunity of the first signal and receive the first signal at the first transmission opportunity.

[0115] In some implementations, the reception of the first signal by the first terminal device may be triggered when reception or detection of the first channel fails.

[0116] In some implementations, the first transmission opportunity is the first transmission opportunity of the one or more transmission opportunities that is located after the first channel in the time domain. That is, after the first terminal device fails to detect or receive the first channel, it may begin detecting or receiving the first signal at the first transmission opportunity after the first channel. Of course, if the first terminal device successfully detects or receives the first channel, it may not detect or receive the first signal.

[0117] In some implementations, the first signal is triggered when the network device determines that the paging of the terminal device has failed. For example, the network device schedules the paging information of the first terminal device and waits for the first terminal device to connect to the network, but the network device does not receive the connection request sent by the first terminal device. If this happens, the network device can determine (or infer) that the first terminal device has missed the above-mentioned paging information. Then, the network device can send a first signal to the first terminal device to alert the first terminal device. The reason why the first terminal device missed the paging information may be that the terminal device is located in a poor signal (such as satellite signal) reception environment. Therefore, the sending of the first signal helps the first terminal device to instruct the user to move to a location with better signal (such as satellite signal) through its own user interface.

[0118] Taking the first signal as an alarm signal as an example, referring to FIG9 , if the network device determines that the first terminal device has missed the paging information, the network device may send an alarm signal on the configured AO. After receiving the alarm signal, the physical layer of the first terminal device may send an alarm signal to the upper layer (the alarm signal corresponds to the target signal mentioned above).

[0119] After sending the paging information to the first terminal device, the network device may not immediately notice that the first terminal device has missed the paging information. That is, it may take some time for the network device to notice that the first terminal device has missed the paging information. Therefore, the network device may not immediately send the first signal to the first terminal device at the first transmission opportunity after the PO that carries the paging information (the difference transmission opportunity of the first signal). In this case, there is no need for the first terminal device to detect or receive the first signal at the first transmission opportunity after the PO. Therefore, in some implementations, as shown in Figure 10, after the terminal device fails to receive the paging information, it can wait for the first time interval before starting to detect or receive the first signal (such as an alarm signal).

[0120] Taking the case where the first channel carries paging information and the first terminal device fails to receive the first channel, or the first channel schedules the transmission of paging information and the first terminal device fails to detect the first channel as an example, the first terminal device can receive or detect the first signal at the first transmission timing (the configured transmission timing of the first signal) after the first channel. The time interval between the first channel and the first transmission time is greater than or equal to the first time interval. The first time interval can be calculated from the time domain start position or the time domain end position of the first channel.

[0121] Taking the case where the paging message reception of the first PO fails and the first terminal device receives or detects the first signal at the first transmission opportunity (the configured transmission opportunity of the first signal) after the first PO as an example, the time interval between the first PO and the first transmission time may be greater than or equal to the first time interval. The first time interval may be calculated from the time domain start position or the time domain end position of the first PO.

[0122] The first time interval mentioned above can be determined based on configuration information, pre-configuration information or autonomous implementation of the terminal device. For example, the first time interval can be indicated or configured by the network device to the first terminal device through a system message or RRC signaling.

[0123] In some implementations, the first transmission opportunity is associated with an identifier of the first terminal device. Taking the first signal as an alarm signal as an example, if the first terminal device detects or receives the alarm signal at the alarm opportunity associated with the identifier of the first terminal device, the alarm signal is the alarm signal of the first terminal device.

[0124] In some implementations, the first transmission opportunity is associated with one or more terminal devices including the first terminal device. Alternatively, the first transmission opportunity is associated with the identifier of one or more terminal devices including the first terminal device. Exemplarily, the association relationship between the identifier of the terminal device and the transmission opportunity of the first signal can be determined based on the following formula: UE ID mod N; wherein UE ID represents the identifier of the terminal device, N is a positive integer, and mod represents remainder. In this way, one transmission opportunity of the first signal may be associated with one or more terminal devices. In this case, the first transmission opportunity may include the first signal corresponding to each of the one or more terminal devices. For example, the first transmission opportunity may be associated with M terminal devices (M is a positive integer greater than or equal to 1), and accordingly, the first transmission opportunity includes a bit map, and the bit map includes M bits. The M bits correspond one-to-one to the M terminal devices. If the value of the i-th bit in the M bits is the first value (such as 0), it can indicate that the first transmission opportunity does not include the first signal of the terminal device corresponding to the i-th bit; if the value of the i-th bit in the M bits is the second value (such as 1), it can indicate that the first transmission opportunity includes the first signal of the terminal device corresponding to the i-th bit.

[0125] In some implementations, the first signal is carried on a first channel. The first channel is used to schedule the transmission of paging information for the first terminal device. The first channel may be a PDCCH. The PDCCH schedules a PDSCH, which carries the paging information for the first terminal device. For example, the first terminal device may detect the PDCCH during a paging opportunity, and then may detect DCI in the PDCCH, where the DCI may include the first signal mentioned above (e.g., an alarm signal).
