Description

Signaling detection method, signaling sending method, terminal, base station and communication system Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a signaling detection method, a signaling sending method, a terminal, a base station, and a communication system. Background Art

[0002] The continuous emergence of new internet applications such as augmented reality (AR) / virtual reality (VR) and vehicle-to-vehicle communications has placed higher demands on wireless communication technology, driving its continuous evolution to meet these demands. Currently, cellular mobile communication technology is in the process of evolving into a new generation of technology. A key feature of this new generation of technology is its flexible configuration to support multiple service types. Different service types have different requirements for wireless communication technology. For example, enhanced mobile broadband (eMBB) services primarily require high bandwidth and high speeds; URLLC services primarily require high reliability and low latency; and massive machine type communication (mMTC) services primarily require a large number of connections. Therefore, the next generation of wireless communication systems requires flexible and configurable designs to support the transmission of multiple service types.

[0003] In the study of wireless communication technology, satellite communication is considered an important aspect of future wireless communication technology development. Satellite communication refers to communication conducted by ground-based radio communication equipment using satellites as relays. Satellite communication systems consist of satellite and ground components. Satellite communication features include: a wide communication range; communication between any two points within the coverage area of ​​the satellite's radio waves; and low susceptibility to land-based disasters (high reliability). As a supplement to current ground-based cellular communication systems, satellite communication can provide the following benefits:

[0004] 1. Extended coverage: For areas that are not covered by current cellular communication systems or are costly to cover, such as oceans, deserts, and remote mountainous areas, satellite communications can be used to solve communication problems.

[0005] 2. Emergency communications: In extreme situations such as disasters such as earthquakes, when cellular communication infrastructure is unavailable, satellite communications can be used to quickly establish communication connections.

[0006] 3. Provide industry applications: For example, for delay-sensitive services with long-distance transmission, satellite communications can be used to reduce the delay of service transmission.

[0007] It can be foreseen that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the intelligent connection of all things.

[0008] Since the signal transmission distance between the satellite and the terminal in the satellite communication system is relatively long, the signal transmission attenuation may be relatively large, affecting the information interaction between the terminal and the base station, so coverage enhancement is needed.

[0153] FIG2 is an interactive schematic diagram showing a signaling sending method according to an embodiment of the present disclosure.

[0154] As shown in FIG2 , the signaling sending method includes:

[0155] In S201, the base station sends a first type of downlink signaling to the terminal.

[0156] In some embodiments, the first type of downlink signaling includes paging signaling or downlink scheduling instructions.

[0157] In some embodiments, the terminal may detect the first type of downlink signaling. In one possible implementation, the terminal may detect the first type of downlink signaling sent by the base station. In another possible implementation, the terminal may not detect the first type of downlink signaling sent by the base station.

[0158] In S202, the base station sends a second type of downlink signaling to the terminal.

[0159] In some embodiments, the second type of downlink signaling includes pre-paging signaling or early warning signaling.

[0160] In some embodiments, the base station determines that the terminal has not detected the first type of downlink signaling and sends the second type of downlink signaling to the terminal. In one possible implementation, the base station sends the first type of downlink signaling to the terminal and determines that the terminal has not detected the first type of downlink signaling and may send the second type of downlink signaling to the terminal. In another possible implementation, the base station does not send the first type of downlink signaling to the terminal and sends the second type of downlink signaling to the terminal.

[0161] In some embodiments, the terminal determines that the first type of downlink signaling is not detected, and detects the second type of downlink signaling.

[0162] In a possible implementation, in response to determining that a duration during which the first type of downlink signaling is not detected reaches a first threshold, the terminal detects the second type of downlink signaling.

[0163] In some embodiments, the second type of downlink signaling is used to indicate whether there is a missed detection of the first type of downlink signaling.

[0164] In one possible implementation, the second type of downlink signaling includes first information and / or second information, wherein the first information is used to indicate whether there is a missed detection of the first type of downlink signaling, and the second information is used to indicate the paging purpose of the second type of downlink signaling.

[0165] In one possible implementation, the paging purpose includes at least one of the following: notifying the terminal to improve channel conditions to support receiving the first type of downlink signaling sent by the base station; notifying the terminal that downlink service has arrived; notifying the terminal that the base station has not sent the first type of downlink signaling.

[0166] In some embodiments, the second type of downlink signaling is directed to one terminal.

[0167] In some embodiments, the second type of downlink signaling is directed to multiple terminals. In this case, the method further includes: determining the first information directed to the terminal and / or the second information directed to the terminal in the detected second type of downlink signaling.

[0168] In some embodiments, the terminal detects the second type of downlink signaling according to the detection configuration information of the second type of downlink signaling.

[0169] In one possible implementation, the detection configuration information of the second type of downlink signaling includes at least one of the following: the start detection condition of the second type of downlink signaling; the stop detection condition of the second type of downlink signaling; the detection period of the second type of downlink signaling; the time domain detection position of the second type of downlink signaling; the frequency domain detection position of the second type of downlink signaling; the detection method of the second type of downlink signaling; the number of repeated transmissions of the second type of downlink signaling; and a temporary wireless network identifier for receiving the second type of downlink signaling.

[0170] In a possible implementation, the detection method of the second type of downlink signaling includes at least one of the following: the format of the second type of downlink signaling; the aggregation level of the second type of downlink signaling; and the number of detection times of the second type of downlink signaling.

[0171] In some embodiments, before S202, the method further includes: determining detection configuration information of the second-type downlink signaling.

[0172] In one possible implementation, the method for determining the detection configuration information of the second type of downlink signaling includes at least one of the following: determining the detection configuration information of the second type of downlink signaling based on a predefined method; receiving the detection configuration information of the second type of downlink signaling sent by the base station.

[0173] In S203, the terminal sends feedback information regarding the second type of downlink signaling to the base station.

[0174] In some embodiments, after detecting the second type of downlink signaling sent by the base station, the terminal sends feedback information for the second type of downlink signaling to the base station.

[0175] In some embodiments, the feedback information for the second type of downlink signaling is used to indicate that the terminal has received the second type of downlink signaling.

[0176] In some embodiments, based on detecting the second type of downlink signaling, it is determined that there is a missed detection of the first type of downlink signaling, and the terminal performs an operation for improving the channel condition.

[0177] In some embodiments, the base station may receive feedback information for the second type of downlink signaling sent by the terminal.

[0178] In S204, the base station resends the first type of downlink signaling to the terminal.

[0179] In some embodiments, the terminal may continue to detect the first type of downlink signaling.

[0180] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to S204. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, step S204 may be implemented as an independent embodiment, steps S201+S202 may be implemented as an independent embodiment, steps S202+S203 may be implemented as an independent embodiment, steps S202+S204 may be implemented as an independent embodiment, and steps S201+S202+S204 may be implemented as an independent embodiment, but are not limited thereto.

[0181] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0182] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0183] In some embodiments, step S203 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0184] In some embodiments, step S204 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0185] In some embodiments, reference may be made to other optional embodiments described before or after the description corresponding to FIG. 2 .

[0186] In some embodiments, due to the long signal transmission distance between satellites and terminals in satellite communication systems, transmission delays are significant, resulting in large gNB DL-UL frame timing shifts. Therefore, terminals need to maintain uplink synchronization based on Global Navigation Satellite System (GNSS) measurements and some auxiliary information. In one possible implementation, the terminal needs to report its own location information to determine delay parameters, such as timing advance (TA), which can be used to compensate for transmission delays.

[0187] For example, see Figures 3 and 4. Figure 3 is a schematic diagram illustrating a base station-side uplink and downlink timing alignment according to an embodiment of the present disclosure, and Figure 4 is a schematic diagram illustrating a base station-side uplink and downlink timing misalignment according to an embodiment of the present disclosure. The gNB can notify the UE of the time interval (TA), where the TA value depends on the signal transmission delay from the gNB to different UEs. The UE can then advance uplink transmissions based on the TA value, ensuring that uplink data from different UEs arrives at the gNB simultaneously. Figure 3 illustrates a method for implementing base station-side uplink and downlink timing alignment, while Figure 4 illustrates a method for implementing base station-side uplink and downlink timing misalignment.

[0188] In some embodiments, due to the long signal transmission distance between the satellite and the terminal in a satellite communication system, the signal transmission attenuation may be relatively large, affecting the information exchange between the terminal and the base station. Therefore, it is necessary to enhance the uplink and downlink coverage. Among them, the uplink coverage enhancement may include enhancing the transmission mechanism of signals such as the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH), and the downlink coverage enhancement may include enhancing the transmission mechanism of signals such as the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH).

[0189] Current coverage enhancement mechanisms cannot fully address coverage issues in satellite communication scenarios. For example, according to 3GPP TR 38.811, at a 30-degree elevation angle, terminals in suburban and rural scenarios have a 10% probability of experiencing non-line-of-sight (NLOS) transmissions. In this case, the terminal's signal fading (shadow fading and clutter loss) can be as high as 18dB.

[0190] Please refer to Figure 5, which is a schematic diagram of a satellite communication scenario according to an embodiment of the present disclosure. As shown in Figure 5, signals can be transmitted between the UE and the satellite via a service link, and communication can be carried out between the ground station and the satellite via a feeder link. The service link and the feeder link are logical links, not physical links. The service link between the UE and the satellite may also include other ground stations, and signals can also be transmitted between the UE and the ground stations, which are not shown one by one in Figure 5. Among them, the ground station can also be called a ground base station and can access the data network.

[0191] In some embodiments, the UE can send paging signaling to the base station to report its own location information; the base station can broadcast the paging signaling to each UE within the coverage area via satellite and wait for these UEs to respond to the paging signaling; if a UE responds to the paging signaling, the base station can allocate an available time slot to the UE to establish a communication connection.

[0192] In the above embodiment, in the case of limited coverage in the satellite communication scenario, the channel condition of the terminal is poor and it may not be able to receive the downlink signaling sent by the base station or even maintain the communication connection, resulting in a large service transmission delay.

[0193] In a first aspect, embodiments of the present disclosure provide a signaling detection method. Figure 6 is a schematic flow chart illustrating a signaling detection method according to an embodiment of the present disclosure. The signaling detection method illustrated in this embodiment may be executed by a terminal.

[0194] As shown in FIG6 , the signaling detection method may include the following steps:

[0195] In S601, it is determined that no first type of downlink signaling is detected, and a second type of downlink signaling is detected, wherein the second type of downlink signaling is used to indicate whether there is any missed detection of the first type of downlink signaling.

[0196] For example, if the terminal determines that it has not detected the first type of downlink signaling, it may detect the second type of downlink signaling, and the second type of downlink signaling indicates that there has been a missed detection of the first type of downlink signaling. That is, if the terminal detects the second type of downlink signaling, it can be determined based on the indication of the second type of downlink signaling that the base station sent the first type of downlink signaling to the terminal and the terminal missed detecting the first type of downlink signaling.

[0197] For example, if the terminal determines that it has not detected the first type of downlink signaling, it may detect the second type of downlink signaling, and the second type of downlink signaling indicates that there is no missed detection of the first type of downlink signaling. That is, if the terminal detects the second type of downlink signaling, it can be determined based on the indication of the second type of downlink signaling that the base station did not send the first type of downlink signaling to the terminal, and therefore the terminal did not miss the first type of downlink signaling.

[0198] In some embodiments, the first type of downlink signaling includes paging signaling or downlink scheduling instructions.

[0199] In some embodiments, the second type of downlink signaling includes pre-paging signaling or pre-alert signaling.

[0200] For example, the first type of downlink signaling is paging signaling, and the second type of downlink signaling is pre-paging signaling.

[0201] In some embodiments, the detection performance of the second type of downlink signaling is better than that of the first type of downlink signaling.

[0202] It should be noted that, in the related art, if the terminal does not detect the first type of downlink signaling, the terminal cannot determine whether the reason for the failure to detect is that the terminal missed detection or the base station did not send it, and therefore cannot perform the corresponding adjustment operation; in the embodiment of the present disclosure, if the terminal detects the second type of downlink signaling, it can promptly know whether it has missed the detection of the first type of downlink signaling, which is beneficial for the terminal to promptly determine whether it needs to perform the corresponding adjustment operation to improve the channel conditions and avoid affecting the service. For example, in the related art, if the base station sends a paging signaling to the terminal, and the terminal cannot receive the paging signaling sent by the base station due to poor channel conditions, it will cause the service transmission delay to be too high; in the embodiment of the present disclosure, if the terminal does not detect the paging signaling, but detects the pre-paging signaling, and the pre-paging signaling indicates that there is a missed detection of the paging signaling, then the terminal can promptly improve the channel conditions to support the reception of the paging signaling and ensure the normal transmission of the downlink service.

[0203] It should be noted that the embodiment shown in FIG. 6 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0204] Optionally, the base station may send a second type of downlink signaling to the terminal.

[0205] In some embodiments, after sending a first type of downlink signaling to a terminal and determining that the terminal has not detected the first type of downlink signaling, the base station may send a second type of downlink signaling to the terminal. In one possible implementation, the base station determining that the terminal has not detected the first type of downlink signaling may include: the base station not receiving feedback information sent by the terminal regarding the first type of downlink signaling. The feedback information regarding the first type of downlink signaling may specifically include, but is not limited to, a random access request, an uplink synchronization signal, and the like.

[0206] For example, the base station may send a first type of downlink signaling to the terminal; if the base station determines that the feedback information sent by the terminal for the first type of downlink signaling has not been received for a predefined period of time, it sends a second type of downlink signaling to the terminal, and the second type of downlink signaling is used to indicate that there is a missed detection of the first type of downlink signaling.

[0207] In some embodiments, the base station does not send the first type of downlink signaling to the terminal, and sends the second type of downlink signaling to the terminal.

[0208] For example, when the base station does not send the first type of downlink signaling to the terminal, it may send the second type of downlink signaling to the terminal, where the second type of downlink signaling is used to indicate that there is no missed detection of the first type of downlink signaling.

[0209] According to an embodiment of the present disclosure, if a terminal determines that it has not detected the first type of downlink signaling, it can detect the second type of downlink signaling. The second type of downlink signaling is used to indicate whether there has been a missed detection of the first type of downlink signaling. Accordingly, in satellite communication scenarios with limited coverage, downlink coverage enhancement can be achieved. The base station can indicate to the terminal via the second type of downlink signaling whether there has been a missed detection of the first type of downlink signaling, so that the terminal can learn whether there has been a missed detection of the first type of downlink signaling based on the second type of downlink signaling. The terminal can then determine whether channel conditions need to be improved to support timely detection of the first type of downlink signaling sent by the base station, ensuring that the latency of service transmission meets the requirements.

[0210] In some embodiments, before step S601, the method may further include: determining detection configuration information of the second-type downlink signaling.

[0211] In some possible implementations, the method for determining the detection configuration information may include at least one of the following: determining the detection configuration information of the second type of downlink signaling based on a predefined method; receiving the detection configuration information of the second type of downlink signaling sent by the base station.

[0212] For example, the detection configuration information of the second type of downlink signaling may be predefined; in this case, the terminal may determine the detection configuration information of the second type of downlink signaling based on a predefined manner, and detect the second type of downlink signaling according to the predefined detection configuration information.

[0213] For example, the detection configuration information of the second type of downlink signaling can be configured by the base station for the terminal; in this case, the terminal can receive the detection configuration information of the second type of downlink signaling sent by the base station, and detect the second type of downlink signaling according to the received detection configuration information.

[0214] For example, the detection configuration information of the second type of downlink signaling can be determined based on a combination of pre-defined and signaling notifications; in this case, the terminal can determine a portion of the detection configuration information in a pre-defined manner and determine another portion of the detection configuration information based on the received signaling. For example, the terminal can determine the detection starting position of the second type of downlink signaling, the number of repeated transmissions of the second type of downlink signaling, and other detection configuration information in a pre-defined manner, and the terminal can determine the time-frequency detection position of the second type of downlink signaling and other detection configuration information by receiving the signaling notification sent by the base station.

[0215] The base station may send the detection configuration information of the second type of downlink signaling to the terminal through system information or high-layer signaling. For example, the base station may send the detection configuration information of the second type of downlink signaling to the terminal through radio resource control (RRC), MAC control element (MAC CE), or physical layer signaling.

[0216] In some embodiments, the detection configuration information includes at least one of the following: the start detection condition of the second type of downlink signaling; the stop detection condition of the second type of downlink signaling; the detection period of the second type of downlink signaling; the time domain detection position of the second type of downlink signaling; the frequency domain detection position of the second type of downlink signaling; the detection method of the second type of downlink signaling; the number of repeated transmissions of the second type of downlink signaling; and the Radio Network Temporary Identifier (RNTI) for receiving the second type of downlink signaling.

[0217] The detection method of the second type of downlink signaling is used to determine how to detect the second type of downlink signal. The detection method of the second type of downlink signaling includes at least one of the following: the format of the second type of downlink signaling; the aggregation level of the second type of downlink signaling; and the number of detection times of the second type of downlink signaling.

[0218] In some embodiments, the detection start condition is whether a duration during which the first type of downlink signaling is not detected reaches a first threshold. In this case, determining that the first type of downlink signaling is not detected and detecting the second type of downlink signaling includes: detecting the second type of downlink signaling in response to determining that a duration during which the first type of downlink signaling is not detected reaches a first threshold. The first threshold may be predefined or configured by the base station for the terminal.

[0219] For example, please refer to Figure 7, which is a schematic diagram of a time domain detection position according to an embodiment of the present disclosure. As shown in Figure 7, the terminal can first detect paging information within a first time period; if the terminal does not detect paging information within the first time period and does not detect paging information until the end of the second time period, the terminal can detect pre-paging information within a third time period. The first time period can be a detection period for paging signaling, the second time period can be a predefined time interval, the third time period can be a detection period for pre-paging information, and the first threshold can be the duration of the second time period, or the sum of the durations of the first time period and the second time period.

[0220] In some embodiments, the second type of downlink signaling may include first information and / or second information, wherein the first information is used to indicate whether there is a missed detection of the first type of downlink signaling, and the second information is used to indicate the paging purpose of the second type of downlink signaling.

[0221] In some possible implementations, the paging purpose may include at least one of the following: notifying the terminal to improve channel conditions to support receiving the first type of downlink signaling sent by the base station; notifying the terminal that downlink service has arrived; notifying the terminal that the base station has not sent the first type of downlink signaling.

[0222] For example, the second-type downlink signaling may include first information, the size of the first information being 1 bit. When the value of the first information is "0," it indicates that the first-type downlink signaling is missed; and when the value of the first information is "0," it indicates that the first-type downlink signaling is not missed.

[0223] For example, the second type of downlink signaling may include second information, and the size of the second information is 2 bits. Among them, when the second information takes the value of "00", it indicates that the paging purpose of the second type of downlink signaling is "early warning information", that is, notifying the terminal to improve the channel conditions to support the reception of the first type of downlink signaling sent by the base station; when the second information takes the value of "01", it indicates that the paging purpose of the second type of downlink signaling is "downlink service arrival", that is, notifying the terminal that the downlink service has arrived, implicitly indicating that the terminal needs to improve the channel conditions as soon as possible to support service data transmission; when the second information takes the value of "10", it indicates that the paging purpose of the second type of downlink signaling is "no paging", that is, notifying the terminal that the base station has not sent the first type of downlink signaling, implicitly indicating that the terminal does not need to improve the channel conditions; when the second information takes the value of "11", it indicates that the paging purpose of the second type of downlink signaling is "reserved", that is, other customized paging purposes.

[0224] It should be noted that in the above embodiment, the size of the second information being 2 bits is merely an exemplary description and does not specifically limit the present disclosure. The size of the second information can be determined according to the number of paging destination types that the base station needs to indicate to the terminal.

[0225] For example, the second type of downlink signaling may include first information and second information, which will not be described in detail here.

[0226] In some embodiments, the second type of downlink signaling may be directed to one terminal or to multiple terminals.

[0227] In a possible implementation, the second type of downlink signaling is directed to one terminal.

[0228] For example, the second type of downlink signaling sent by the base station to terminal #1 is for one terminal and is used to indicate whether terminal #1 has missed detection of the first type of downlink signaling.

[0229] In another possible implementation, the second type of downlink signaling is for multiple terminals. In this case, the method further includes: determining the first information for the terminal and / or the second information for the terminal in the detected second type of downlink signaling.

[0230] For example, the second type of downlink signaling sent by the base station to terminal #1 is for multiple terminals, and is used to indicate whether the first type of downlink signaling is missed for terminal #1, terminal #2 and terminal #3 in terminal group group #1; in this case, the second type of downlink signaling for terminal group group #1 may include the first information for terminal #1, the first information for terminal #2 and the first information for terminal #3; after detecting the second type of downlink signaling for terminal group group #1, terminal #1 can first determine the first information for terminal #1 therefrom to determine whether the first type of downlink signaling of this terminal is missed.

[0231] In some embodiments, the method may further include: after detecting the second type of downlink signaling sent by the base station, sending feedback information for the second type of downlink signaling to the base station, wherein the feedback information is used to indicate that the terminal has received the second type of downlink signaling.

[0232] For example, if the terminal determines that the first type of downlink signaling is not detected, it can detect the second type of downlink signaling, and the second type of downlink signaling indicates that there is a missed detection of the first type of downlink signaling; further, the terminal can send feedback information for the second type of downlink signaling to the base station, and the feedback information is used to indicate that the terminal has received the second type of downlink signaling.

[0233] In some other embodiments, after detecting the second type of downlink signaling sent by the base station, the terminal does not need to send feedback information for the second type of downlink signaling to the base station.

[0234] In some embodiments, the method may further include: determining that there is missed detection of the first type of downlink signaling based on the detection of the second type of downlink signaling, performing an operation for improving channel conditions; and continuing to detect the first type of downlink signaling.

[0235] For example, if the terminal determines that the first type of downlink signaling is not detected, it may detect the second type of downlink signaling, where the second type of downlink signaling indicates that there is a missed detection of the first type of downlink signaling; further, the terminal may send feedback information for the second type of downlink signaling to the base station, where the feedback information is used to indicate that the terminal has received the second type of downlink signaling, and the terminal may perform operations for improving channel conditions; further, the terminal may continue to detect the first type of downlink signaling.

[0236] For example, if the terminal determines that the first type of downlink signaling is not detected, it can detect the second type of downlink signaling, and the second type of downlink signaling indicates that there is a missed detection of the first type of downlink signaling; further, there is no need to send feedback information for the second type of downlink signaling to the base station, and operations for improving channel conditions can be directly performed; further, the terminal can continue to detect the first type of downlink signaling.

[0237] The operations for improving the channel condition may include but are not limited to: moving the terminal to an open area, moving the terminal out of a confined space (such as a backpack, a pocket of clothes, etc.).

[0238] Optionally, the base station may receive feedback information for the second type of downlink signaling sent by the terminal. In a further embodiment, the base station may resend the first type of downlink signaling to the terminal.

[0239] In the above embodiment, after the terminal learns that there is a missed detection of the first type of downlink signaling through the detected second type of downlink signaling, it can perform an operation for improving the channel condition and send feedback information of the second type of downlink signaling to the base station, so that the base station can quickly learn that the terminal has learned of the previous missed detection and improved its own channel condition to support subsequent detection of the first type of downlink signaling. Then, the base station can resend the first type of downlink signaling to the terminal so that the terminal can detect the resent first type of downlink signaling as soon as possible. Accordingly, in the case of limited coverage in the satellite communication scenario, in addition to supporting the terminal to promptly detect the first type of downlink signaling sent by the base station and ensure that the service transmission delay meets the requirements, compared with the implementation method in which the base station continuously and repeatedly sends the first type of downlink signaling and the terminal continuously detects the first type of downlink signaling, it can reduce the power consumption of the base station's signaling transmission and the terminal's signaling detection.

[0240] In a second aspect, embodiments of the present disclosure provide a signaling transmission method. Figure 8 is a schematic flow chart illustrating a signaling transmission method according to an embodiment of the present disclosure. The signaling transmission method illustrated in this embodiment may be executed by a base station.

[0241] As shown in FIG8 , the signaling sending method may include the following steps:

[0242] In S801, a second type of downlink signaling is sent to a terminal, wherein the second type of downlink signaling is used to indicate whether there is a missed detection of the first type of downlink signaling.

[0243] For example, after sending the first type of downlink signaling to the terminal, the base station may send the second type of downlink signaling to the terminal, where the second type of downlink signaling indicates that there is a missed detection of the first type of downlink signaling.

[0244] For example, if the base station determines that no first type downlink signaling is sent to the terminal in the current sending cycle of the first type downlink signaling, it may send second type downlink signaling to the terminal, where the second type downlink signaling indicates that there is no missed detection of the first type downlink signaling.

[0245] Optionally, the terminal determines that no first-type downlink signaling is detected and may detect second-type downlink signaling.

[0246] In some embodiments, the first type of downlink signaling includes paging signaling or downlink scheduling instructions.

[0247] In some embodiments, the second type of downlink signaling includes pre-paging signaling or early warning signaling.

[0248] It should be noted that in the related art, if the base station sends a first type of downlink signaling to the terminal and does not receive feedback information from the terminal regarding the first type of downlink signaling, the base station may resend the first type of downlink signaling. However, if the channel condition of the terminal is not good and it is unable to receive the first type of downlink signaling sent by the base station, the terminal is likely to be unable to receive the first type of downlink signaling resent by the base station; or, the base station may believe that there is no terminal within the coverage of the base station that needs to respond to the first type of downlink signaling and no longer resend the first type of downlink signaling, which will result in service transmission failure. In an embodiment of the present disclosure, in order to inform the terminal of the reason why the first type of downlink signaling was not detected, if the base station determines that the terminal has not detected the first type of downlink signaling, it can send a second type of downlink signaling to the terminal, so that the terminal can determine whether there is a missed detection of the first type of downlink signaling based on the second type of downlink signaling, and then the terminal can determine whether it is necessary to perform relevant adjustment operations to improve the channel conditions, thereby supporting the detection of the first type of downlink signaling.

[0249] It should be noted that the embodiment shown in FIG8 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0250] According to an embodiment of the present disclosure, a base station can send a second type of downlink signaling to a terminal. The second type of downlink signaling is used to indicate whether there has been a missed detection of the first type of downlink signaling. Accordingly, in satellite communication scenarios with limited coverage, downlink coverage enhancement can be achieved. The base station can use the second type of downlink signaling to indicate to the terminal whether there has been a missed detection of the first type of downlink signaling. The terminal can then determine whether there has been a missed detection of the first type of downlink signaling based on the second type of downlink signaling. The terminal can then determine whether channel conditions need to be improved to enable timely detection of the first type of downlink signaling sent by the base station, ensuring that service transmission latency meets requirements.

[0251] In some embodiments, the base station determines that the terminal does not detect the first type of downlink signaling and may send the second type of downlink signaling to the terminal.

[0252] In one possible implementation, after sending first-type downlink signaling to a terminal and determining that the terminal has not detected the first-type downlink signaling, the base station may send second-type downlink signaling to the terminal. In one possible implementation, the base station determining that the terminal has not detected the first-type downlink signaling may include: the base station not receiving feedback information sent by the terminal regarding the first-type downlink signaling. The feedback information regarding the first-type downlink signaling may specifically include, but is not limited to, a random access request, an uplink synchronization signal, and the like.

[0253] For example, the base station may send a first type of downlink signaling to the terminal; if the base station determines that the feedback information sent by the terminal for the first type of downlink signaling has not been received for a predefined period of time, it sends a second type of downlink signaling to the terminal, and the second type of downlink signaling is used to indicate that there is a missed detection of the first type of downlink signaling.

[0254] In some embodiments, the base station does not send the first type of downlink signaling to the terminal, and sends the second type of downlink signaling to the terminal.

[0255] For example, when the base station does not send the first type of downlink signaling to the terminal, it may send the second type of downlink signaling to the terminal, where the second type of downlink signaling is used to indicate that there is no missed detection of the first type of downlink signaling.

[0256] In some embodiments, the method further includes: determining detection configuration information of the second type of downlink signaling.

[0257] In some possible implementations, the base station may determine the detection configuration information of the second-type downlink signaling based on a predefined method.

[0258] In some other possible implementations, the base station may determine detection configuration information for the second-type downlink signaling and send the detection configuration information for the second-type downlink signaling to the terminal. The base station may send the detection configuration information for the second-type downlink signaling to the terminal via system information or higher-layer signaling. For example, the base station may send the detection configuration information for the second-type downlink signaling to the terminal via RRC, MAC CE, or physical layer signaling.

[0259] In some embodiments, the detection configuration information includes at least one of the following: the start detection condition of the second type of downlink signaling; the stop detection condition of the second type of downlink signaling; the detection period of the second type of downlink signaling; the time domain detection position of the second type of downlink signaling; the frequency domain detection position of the second type of downlink signaling; the detection method of the second type of downlink signaling; the number of repeated transmissions of the second type of downlink signaling; and the RNTI for receiving the second type of downlink signaling.

[0260] The detection method of the second type of downlink signaling is used to determine how to detect the second type of downlink signal. The detection method of the second type of downlink signaling includes at least one of the following: the format of the second type of downlink signaling; the aggregation level of the second type of downlink signaling; and the number of detection times of the second type of downlink signaling.

[0261] In some embodiments, the start detection condition is whether the duration during which the terminal does not detect the first type of downlink signaling reaches the first threshold.

[0262] In some embodiments, the second type of downlink signaling may include first information and / or second information, wherein the first information is used to indicate whether there is a missed detection of the first type of downlink signaling, and the second information is used to indicate the paging purpose of the second type of downlink signaling.

[0263] In some possible implementations, the paging purpose may include at least one of the following: notifying the terminal to improve channel conditions to support receiving the first type of downlink signaling sent by the base station; notifying the terminal that downlink service has arrived; notifying the terminal that the base station has not sent the first type of downlink signaling.

[0264] For example, the second-type downlink signaling may include first information, the size of the first information being 1 bit. When the value of the first information is "0," it indicates that the first-type downlink signaling is missed; and when the value of the first information is "0," it indicates that the first-type downlink signaling is not missed.

[0265] For example, the second type of downlink signaling may include second information, and the size of the second information is 2 bits. Among them, when the second information takes the value of "00", it indicates that the paging purpose of the second type of downlink signaling is "early warning information", that is, notifying the terminal to improve the channel conditions to support the reception of the first type of downlink signaling sent by the base station; when the second information takes the value of "01", it indicates that the paging purpose of the second type of downlink signaling is "downlink service arrival", that is, notifying the terminal that the downlink service has arrived, implicitly indicating that the terminal needs to improve the channel conditions as soon as possible to support service data transmission; when the second information takes the value of "10", it indicates that the paging purpose of the second type of downlink signaling is "no paging", that is, notifying the terminal that the base station has not sent the first type of downlink signaling, implicitly indicating that the terminal does not need to improve the channel conditions; when the second information takes the value of "11", it indicates that the paging purpose of the second type of downlink signaling is "reserved", that is, other customized paging purposes.

[0266] It should be noted that in the above embodiment, the size of the second information being 2 bits is merely an exemplary description and does not specifically limit the present disclosure. The size of the second information can be determined according to the number of paging destination types that the base station needs to indicate to the terminal.

[0267] For example, the second type of downlink signaling may include first information and second information, which will not be described in detail here.

[0268] In some embodiments, the second type of downlink signaling may be directed to one terminal or to multiple terminals.

[0269] In some embodiments, the method further includes: receiving feedback information for the second-type downlink signaling sent by the terminal, wherein the feedback information is used to indicate that the terminal has received the second-type downlink signaling.

[0270] For example, the feedback information for the second type of downlink signaling may be 1-bit indication information, wherein when the value of the feedback information is "0", it indicates that the terminal has received the second type of downlink signaling.

[0271] Optionally, after detecting the second type of downlink signaling sent by the base station, the terminal may send feedback information regarding the second type of downlink signaling to the base station. Alternatively, after detecting the second type of downlink signaling sent by the base station, the terminal does not need to send feedback information regarding the second type of downlink signaling to the base station. In a further embodiment, the terminal may also determine that there is a missed detection of the first type of downlink signaling based on the detection of the second type of downlink signaling, perform an operation to improve channel conditions, and continue to detect the first type of downlink signaling.

[0272] In some embodiments, the method may further include: resending the first type of downlink signaling to the terminal.

[0273] In the above embodiment, after the terminal learns that there is a missed detection of the first type of downlink signaling through the detected second type of downlink signaling, it can perform an operation for improving the channel condition and send feedback information of the second type of downlink signaling to the base station, so that the base station can quickly learn that the terminal has learned of the previous missed detection and improved its own channel condition to support subsequent detection of the first type of downlink signaling. Then, the base station can resend the first type of downlink signaling to the terminal so that the terminal can detect the resent first type of downlink signaling as soon as possible. Accordingly, in the case of limited coverage in the satellite communication scenario, in addition to supporting the terminal to promptly detect the first type of downlink signaling sent by the base station and ensure that the service transmission delay meets the requirements, compared with the implementation method in which the base station continuously and repeatedly sends the first type of downlink signaling and the terminal continuously detects the first type of downlink signaling, it can reduce the power consumption of the base station's signaling transmission and the terminal's signaling detection.
