AI Technical Summary
In non-terrestrial networks, when a terminal switches to other network-side devices outside the satellite coverage range, the repeated transmission information may be interrupted, making it difficult to accurately obtain the information sent by the base station.
When the terminal fails to receive the information successfully, it saves the received information in the cache, and after switching to the second network side device, decodes it in combination with the repeated transmission information of the first and second network side devices to ensure the integrity of the information.
Even if the repeated transmission of the first network side device is interrupted, the terminal can still receive and accurately determine the information through the second network side device, thereby increasing the success rate of information reception.

Abstract

Background Art
[0002] In a non-terrestrial network (NTN), a terminal can communicate with a base station via a satellite. Currently, the satellites in NTN are generally not geostationary satellites. Therefore, the satellites are in motion relative to the ground.
[0003] To improve the success rate of a terminal receiving information, downlink coverage enhancement can be performed, and the base station performs repetition transmission, that is, for the same information, it can be repeatedly transmitted to the terminal multiple times.
[0004] When the terminal is within the satellite coverage area, it can communicate with the base station. Since the satellite is in motion, when the terminal leaves the satellite coverage area as the satellite moves, it is necessary to communicate with the base station via other satellites. However, in this case, when the terminal communicates via other satellites, it may switch to other base stations. When the original base station is performing repetition transmission, the repetition transmission will be interrupted, and thus it is difficult for the terminal to accurately obtain the information sent by the base station.

However, for those skilled in the art, it can be understood that the term "greater than" also encompasses the meaning of "greater than or equal to", and the term "less than" also encompasses the meaning of "less than or equal to"; the term "higher than" encompasses the meaning of "higher than or equal to", and the term "lower than" also encompasses the meaning of "lower than or equal to".
[0037] Figure 1 It is a schematic flowchart of an information receiving method shown according to an embodiment of the present disclosure. The information receiving method shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices (such as NB-IoT (Narrow Band Internet of Things), MTC (Machine Type Communication), eMTC (Enhanced Machine Type Communication)). The terminal can communicate with network-side devices, and the network-side devices include but are not limited to network-side devices in communication systems such as 4G, 5G, 6G, etc., such as base stations, core networks, etc.
[0038] As Figure 1 shown, the information receiving method may include the following steps:
[0039] In step S101, receive the first information repeatedly transmitted by the first network-side device;
[0040] In step S102, it is determined that the first information is not successfully received. After switching to the second network-side device, the first information repeatedly transmitted by the second network-side device is received;
[0041] In step S103, the first information is determined based on the first information repeatedly transmitted by the first network-side device and the first information repeatedly transmitted by the second network-side device.
[0042] In one embodiment, the terminal may be a terminal in a non-terrestrial network (NTN). The terminal may communicate with a network-side device through an aerial device such as a satellite. The satellite may send the information sent by the network-side device to the terminal, or may send the information sent by the terminal to the network-side device.
[0043] To ensure that the terminal can successfully receive the information sent by the network-side device, the network-side device may perform repeated transmission. For example, the first network-side device may repeatedly transmit the first information to send the first information to the terminal.
[0044] Since the satellite is in motion in the air at all times, when the terminal is within the satellite coverage area, it can receive the first information repeatedly transmitted by the first network-side device. When the terminal leaves the satellite coverage area as the satellite moves, it is necessary to communicate with the network-side device through other satellites. In this case, when the terminal communicates with the network-side device through other satellites, it may switch to other network-side devices, such as a so-called second network-side device.
[0045] It should be noted that the second network-side device and the first network-side device may be different network-side devices, that is, the terminal communicates with different network-side devices through different satellites; the second network-side device and the first network-side device may also be the same network-side device, that is, the terminal communicates with the same network-side device through different satellites. This situation is equivalent to only switching the satellite without switching the network-side device.
[0046] When the terminal leaves the satellite coverage area, if the first information repeatedly transmitted by the first network-side device is not successfully received, it will cause the repeated transmission to be interrupted. In this case, if the terminal decodes only based on the first information repeatedly transmitted by the first network-side device, it is difficult to successfully obtain the first information.
[0047] According to an embodiment of the present disclosure, during the process of the terminal receiving the first information repeatedly transmitted by the first network-side device, when the first information is not successfully received and it is determined that it is necessary to switch to the second network-side device, the first information repeatedly transmitted by the first network-side device that has been received in the cache may be saved.
[0048] After switching to the second network-side device, the first information repeatedly transmitted by the second network-side device can be received, and then the first information can be determined based on the first information repeatedly transmitted by the first network-side device and the first information repeatedly transmitted by the second network-side device. For example, the first information repeatedly transmitted by the first network-side device and the first information repeatedly transmitted by the second network-side device can be decoded together to obtain the first information. In this process, the second network-side device repeatedly transmits the first information to the terminal, which is equivalent to continuing the repeated transmission that the first network-side device did not complete.
[0049] Accordingly, even if the process of the first network-side device repeatedly transmitting the first information to the terminal is interrupted, after the terminal switches to the second network-side device, it can receive the first information repeatedly transmitted by the second network-side device and accurately determine the first information based on the first information repeatedly transmitted by the first network-side device and the first information repeatedly transmitted by the second network-side device.
[0050] In one embodiment, for example, when the number of times the first network-side device repeatedly transmits the first information is the first number of times, the terminal switches to the second network-side device, and the first number of times is less than the number threshold (the pre-agreed number of times to repeatedly transmit the first information). In this case, if the first network-side determines that the terminal has not successfully received the first information, it can send the first information and the fourth indication information to the second network-side device, and the second network-side device is instructed by the fourth indication information to repeatedly transmit the first information to the terminal.
[0051] The number of times the second network-side device repeatedly transmits the first information can be determined according to the indication of the first network-side device, or can be determined by the second network-side device as needed.
[0052] In one embodiment, the first network-side device determines the remaining number of repeated transmissions (for example, determined according to the difference between the number threshold and the first number of times) based on the first number of times of repeatedly transmitting the first information and the number threshold, for example, called the second number of times, and then the second number of times can be sent to the second network-side device (for example, sent to the second network-side device carried in the fourth indication information). In this case, the number of times the second network-side device repeatedly transmits the first information can be the second number of times.
[0053] In one embodiment, the second network-side device can determine the number of times to repeatedly transmit the first information according to the communication quality of communicating with the terminal. For example, the number of times to repeatedly transmit the first information can be negatively correlated with the communication quality; for example, the second network-side device can determine the number of times to repeatedly transmit the first information according to the frequency-domain resources configured for the terminal. For example, the number of times to repeatedly transmit the first information can be negatively correlated with the frequency-domain resources configured for the terminal.
[0054] In one embodiment, on the basis of receiving the second number of times, the second network-side device may further receive the first communication quality when the first network-side device repeats transmitting the first information to the terminal. After the terminal switches to the second network-side device, the second communication quality of the communication between the second network-side device and the terminal may be determined. Further, the second number of times may be adjusted according to the first communication quality and the second communication quality to determine the number of times the second network-side device repeats transmitting the first information.
[0055] For example, if the second communication quality is greater than the first communication quality, the second number of times may be reduced and used as the number of times the second network-side device repeats transmitting the first information; for example, if the second communication quality is less than the first communication quality, the second number of times may be increased and used as the number of times the second network-side device repeats transmitting the first information; for example, if the second communication quality is equal to the first communication quality, the second number of times may be used as the number of times the second network-side device repeats transmitting the first information.
[0056] In one embodiment, on the basis of receiving the second number of times, the second network-side device may further receive the first frequency-domain resource when the first network-side device repeats transmitting the first information to the terminal. After the terminal switches to the second network-side device, the second frequency-domain resource of the communication between the second network-side device and the terminal may be determined. Further, the second number of times may be adjusted according to the first frequency-domain resource and the second frequency-domain resource to determine the number of times the second network-side device repeats transmitting the first information.
[0057] For example, if the second frequency-domain resource is greater than the first frequency-domain resource, the second number of times may be reduced and used as the number of times the second network-side device repeats transmitting the first information; for example, if the second frequency-domain resource is less than the first frequency-domain resource, the second number of times may be increased and used as the number of times the second network-side device repeats transmitting the first information; for example, if the second frequency-domain resource is equal to the first frequency-domain resource, the second number of times may be used as the number of times the second network-side device repeats transmitting the first information.
[0058] It should be noted that the reasons for the terminal to switch to the second network-side device when it fails to successfully receive the first information include, but are not limited to, that the terminal is about to leave the coverage range of the currently serving satellite.
[0059] Figure 2 is a schematic flowchart of another information reception method shown according to an embodiment of the present disclosure. As Figure 2 shown, the receiving the first information repeatedly transmitted by the second network-side device includes:
[0060] In step S201, the downlink resources are determined according to the scheduling instruction sent by the second network-side device;
[0061] In step S202, receive the first information repeatedly transmitted by the second network-side device on the downlink resource.
[0062] In one embodiment, after the terminal switches to the second network-side device, the second network-side device can configure the downlink resource for the terminal through scheduling signaling, and then repeatedly transmit the first information to the terminal on the configured downlink resource. Correspondingly, the terminal can also receive the first information repeatedly transmitted by the second network-side device on the downlink resource configured by the second network-side device.
[0063] In one embodiment, the second network-side device configures the downlink resource for the terminal as needed and repeatedly transmits the first information to the terminal on the downlink resource. For example, the resources when the second network-side device is idle can be selected as the downlink resource to avoid excessive load on the second network-side device; or the resources when the terminal just switches to the second network-side device can be selected as the downlink resource so that the terminal can successfully receive the first information as soon as possible.
[0064] In one embodiment, the first network-side device can indicate the downlink resource to the second network-side device. For example, before the terminal switches to the second network-side device, the terminal can send a desired information to the first network-side device, which is used to indicate the downlink resource where the terminal expects to receive the first information after switching to the second network-side device. Then, the first network-side device can indicate the downlink resource expected by the terminal to the second network-side device so that the second network-side device can repeatedly transmit the first information to the terminal on the downlink resource expected by the terminal to ensure meeting the needs of the terminal.
[0065] Figure 3 It is a schematic flowchart of another information receiving method shown according to an embodiment of the present disclosure. As Figure 3 shown, the receiving the first information repeatedly transmitted by the second network-side device includes:
[0066] In step S301, determine the first hybrid automatic repeat request process number HPN (HARQ (Hybrid Automatic Repeat reQuest) process number) corresponding to the first information repeatedly transmitted by the first network-side device;
[0067] In step S302, determine the second HPN corresponding to the hybrid automatic repeat request process where the information sent by the second network-side device is located;
[0068] In step S303, when the second HPN is the same as the first HPN, receive the information sent by the second network-side device as the first information repeatedly transmitted by the second network-side device.
[0069] In one embodiment, the first network-side device may perform retransmission of the first information on a HARQ process, and the HPN of the HARQ process in which the retransmission of the first information is located can be determined for both the first network-side device and the terminal.
[0070] When the terminal determines that it needs to switch to the second network-side device, it may, by means of an indication, cause the first network-side device to determine that the terminal is about to switch to the second network-side device. In this case, if the first network-side device determines that the terminal has not successfully received the first information, it may send the first HPN of the HARQ process in which the retransmission of the first information is located to the second network-side device.
[0071] Furthermore, when the second network-side device retransmits the first information to the terminal, the HPN of the HARQ process used may also be the first HPN.
[0072] When the terminal receives information from the second network-side device, it may determine the second HPN of the HARQ process in which the received information is located. When the second HPN is the same as the first HPN, it may be determined that the information sent by the second network-side device is exactly the retransmitted information, so that the information sent by the second network-side device can be received as the retransmitted first information. Accordingly, it can be accurately determined which information sent by the second network-side device is the retransmitted first information, thereby ensuring successful decoding to obtain the first information.
[0073] Figure 4 It is a schematic flowchart of yet another information reception method shown according to an embodiment of the present disclosure. As Figure 4 shown, the method further includes:
[0074] In step S401, it is determined that the duration from the current time to the service end time of the currently served satellite is less than a duration threshold;
[0075] In step S402, a first indication information is sent to the first network-side device, where the first indication information is used to indicate whether the terminal has successfully received the first information.
[0076] In one embodiment, the terminal determines that it needs to switch to the second network-side device, which may be determined based on the duration from the current time to the service end time of the currently served satellite. For example, if the duration from the current time to the service end time of the currently served satellite is less than the duration threshold, the terminal may determine that it is about to leave the coverage range of the currently served satellite, and the currently served satellite is about to interrupt providing service to the terminal.
[0077] In this case, the terminal may send first indication information to the first network-side device according to the reception of the first information. The first network-side device may determine whether the terminal has successfully received the first information based on the first indication information. Among them, the resource for sending the first indication information may be configured by the first network-side device or determined in advance according to protocol agreements.
[0078] Accordingly, the first network-side device may determine whether the terminal has successfully received the first information based on the first indication information. Furthermore, in the case where it is determined that the terminal has not successfully received the first information, the first information and fourth indication information may be sent to the second network-side device. The fourth indication information is used to instruct the second network-side device to retransmit the first information to the terminal. Thus, it is ensured that after the terminal switches to the second network-side device, it can receive the first information retransmitted by the second network-side device.
[0079] Among them, the first network-side device may also determine the remaining number of retransmission times required to retransmit the first information to the terminal, and then the remaining number of retransmission times may also be indicated to the second network-side device (for example, carried in the fourth indication information), so that the network-side device may retransmit the first information to the terminal according to the remaining number of retransmission times. For example, the number of retransmissions is the remaining number of retransmission times.
[0080] In the case where the first network-side device determines that the terminal has successfully received the first information, even if the number of times of retransmitting the first information to the terminal is less than the number threshold (the number of times of retransmitting the first information agreed in advance), there is no need to send the fourth indication information to the second network-side device.
[0081] In one embodiment, the cases where the terminal has successfully received the first information include, but are not limited to, at least one of the following cases:
[0082] The number of times the terminal receives the first information retransmitted by the first network-side device has reached the number threshold;
[0083] The number of times the terminal receives the first information retransmitted by the first network-side device has reached the number threshold, and the terminal decodes according to the repeatedly received first information and successfully obtains the first information;
[0084] The number of times the terminal receives the first information retransmitted by the first network-side device is less than the number threshold, but the terminal decodes according to the repeatedly received first information and successfully obtains the first information. In this case, the terminal may decode according to the repeatedly received first information every time it receives the first information retransmitted a preset number of times. If the decoded first information is correct and complete, it may be determined that the first information has been successfully received; otherwise, it is determined that the first information has been successfully received.
[0085] In one embodiment, the situation where the terminal fails to successfully receive the first information includes, but is not limited to, at least one of the following situations:
[0086] The number of times the terminal receives the first information repeatedly transmitted by the first network - side device has reached the number threshold, but the terminal decodes based on the repeatedly received first information and fails to successfully obtain the first information;
[0087] The number of times the terminal receives the first information repeatedly transmitted by the first network - side device is less than the number threshold;
[0088] The number of times the terminal receives the first information repeatedly transmitted by the first network - side device is less than the number threshold, and the terminal decodes based on the repeatedly received first information and fails to successfully obtain the first information.
[0089] In one embodiment, the method further includes:
[0090] When it is determined that the first information has been successfully received, stop receiving the first information transmitted repeatedly.
[0091] When the terminal has successfully received the first information, even if the number of times the terminal receives the first information repeatedly transmitted by the first network - side device is less than the number threshold, it can stop receiving the first information repeatedly transmitted by the first network - side device to avoid wasting terminal resources. When the first network - side device determines that the terminal has successfully received the first information according to the first indication information, even if the number of times of repeatedly transmitting the first information is less than the number threshold, it can stop repeatedly transmitting the first information to avoid wasting the resources of the first network - side device.
[0092] It should be noted that the function of the terminal actively stopping receiving the first information transmitted repeatedly can be configured by the network - side device. When it is configured that the terminal can actively stop receiving the first information transmitted repeatedly, then when the terminal has completed receiving the first information, even if the number of times the terminal receives the first information repeatedly transmitted by the first network - side device is less than the number threshold, it will stop receiving the first information repeatedly transmitted by the first network - side device; when it is not configured that the terminal can actively stop receiving the first information transmitted repeatedly, when the terminal has completed receiving the first information, if the number of times the terminal receives the first information repeatedly transmitted by the first network - side device is less than the number threshold, it will still receive the first information repeatedly transmitted by the first network - side device.
[0093] Figure 5 It is a schematic flowchart of another information - receiving method shown according to an embodiment of the present disclosure. As Figure 5 shown, before it is determined that the duration from the current time to the service end time of the satellite for the current service is less than the duration threshold, the method further includes:
[0094] In step S501, determine the duration from the current time to the service end time of the satellite for the current service according to the second indication information sent by the first network-side device.
[0095] In one embodiment, the first network-side device may indicate the duration from the current time to the service end time of the satellite for the current service by sending the second indication information to the terminal. Among them, the second indication information is carried in at least one of the following:
[0096] Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE), Physical layer signaling.
[0097] In one embodiment, the second indication information is used to indicate at least one of the following:
[0098] The duration from the current time to the service end time of the satellite for the current service, the service start time and the service duration of the satellite.
[0099] In one embodiment, the first network-side device can directly indicate to the terminal the duration from the current time to the service end time of the satellite for the current service through the second indication information;
[0100] In one embodiment, the first network-side device can indicate the service start time and the service duration of the satellite through the second indication information, and the terminal can determine the duration from the current time to the service end time of the satellite for the current service according to the service start time and the service duration of the satellite. For example, the terminal can first determine the service end time of the satellite according to the sum of the service start time and the service duration of the satellite, and then determine the duration from the current time to the service end time of the satellite for the current service according to the difference between the service end time and the current time.
[0101] It should be noted that the duration from the current time to the service end time of the satellite for the current service can be determined according to the indication of the first network-side device, or can be determined independently by the terminal. For example, the terminal can determine the service end time of the satellite according to the ephemeris information of the satellite movement, and then determine the duration from the current time to the service end time of the satellite for the current service according to the difference between the service end time and the current time.
[0102] Figure 6 It is a schematic flowchart of another information receiving method shown according to an embodiment of the present disclosure. As Figure 6 shown, the determination that the duration from the current time to the service end time of the satellite for the current service is less than the duration threshold includes:
[0103] In step S601, when receiving the third indication information sent by the first network-side device, it is determined that the duration from the current time to the service end time of the currently served satellite is less than the duration threshold.
[0104] In one embodiment, the first network-side device may determine whether the duration from the current time to the service end time of the currently served satellite is less than the duration threshold. When it is determined that the duration from the current time to the service end time of the currently served satellite is less than the duration threshold, the first network-side device may send the third indication information to the terminal. Then, when the terminal receives the third indication information sent by the first network-side device, it can be determined that the duration from the current time to the service end time of the currently served satellite is less than the duration threshold.
[0105] Figure 7 It is a schematic flowchart of an information transmission method shown according to an embodiment of the present disclosure. The information transmission method shown in this embodiment may be executed by a first network-side device. The first network-side device may communicate with a terminal. The first network-side device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices.
[0106] As Figure 7 shown, the information transmission method may include the following steps:
[0107] In step S701, the first information is repeatedly transmitted to the terminal;
[0108] In step S702, the second network-side device to which the terminal will switch is determined;
[0109] In step S703, the first indication information sent by the terminal is received, and it is determined according to the first indication information that the terminal has not completed receiving the first information;
[0110] In step S704, the first information and the fourth indication information are sent to the second network-side device, where the fourth indication information is used to instruct the second network-side device to repeatedly transmit the first information to the terminal.
[0111] In one embodiment, when the first network-side device repeatedly transmits the first information to the terminal, if the terminal determines that it needs to switch to the second network-side device, then the terminal may determine whether it has successfully received the first information, and then send the first indication information to the first network-side device. The first network-side device may determine whether the terminal has successfully received the first information according to the first indication information.
[0112] When the first network-side device determines that the terminal has not successfully received the first information according to the first indication information, it can determine the network-side device to which the terminal is about to switch, for example, called the second network-side device, and then send the first information and the fourth indication information to the second network-side device, and instruct the second network-side device to retransmit the first information to the terminal through the fourth indication information. Then, after the terminal switches to the second network-side device, the second network-side device can retransmit the first information to the terminal according to the fourth indication information. During this process, the second network-side device retransmitting the first information to the terminal is equivalent to continuing the retransmission that the first network-side device did not complete.
[0113] For example, when the first network-side device and the second network-side device are base stations, the first network-side device can send the first information and the fourth indication information to the second network-side device through the interface between the base stations.
[0114] Accordingly, even if the process of the first network-side device retransmitting the first information to the terminal is interrupted, after the terminal switches to the second network-side device, it can receive the retransmitted first information from the second network-side device and accurately determine the first information according to the first information retransmitted by the first network-side device and the first information retransmitted by the second network-side device.
[0115] In one embodiment, the fourth indication information is further used to instruct the second network-side device of the remaining retransmission times of the first information.
[0116] In one embodiment, the first network-side device can also determine the remaining retransmission times of the first information that needs to be retransmitted to the terminal, and then can also indicate the remaining retransmission times to the second network-side device (for example, carried in the fourth indication information), so that the network-side device can retransmit the first information to the terminal according to the remaining retransmission times. For example, the number of retransmissions is the remaining retransmission times. This avoids the second network-side device retransmitting the first information too few times, resulting in the terminal having difficulty in successfully receiving the first information, and also avoids the second network-side device retransmitting the first information too many times, causing resource waste.
[0117] In the case where the first network-side device determines that the terminal has successfully received the first information, even if the number of times of retransmitting the first information to the terminal is less than the number threshold (the pre-agreed number of times of retransmitting the first information), there is no need to send the fourth indication information to the second network-side device.
[0118] In one embodiment, for example, when the number of times the first network-side device repeats transmitting the first information is the first number of times and the first number of times is less than the number threshold (the pre-agreed number of times for repeating the transmission of the first information), the terminal switches to the second network-side device. In this case, if the first network side determines that the terminal has not successfully received the first information, it may send the first information and the fourth indication information to the second network-side device, and use the fourth indication information to instruct the second network-side device to repeat transmitting the first information to the terminal.
[0119] The number of times the second network-side device repeats transmitting the first information may be determined according to the indication of the first network-side device, or may be determined by the second network-side device according to its needs.
[0120] In one embodiment, the first network-side device determines the remaining number of times for repeating the transmission of the first information according to the first number of times of repeating the transmission of the first information and the number threshold (for example, determined according to the difference between the number threshold and the first number of times), for example, referred to as the second number of times. Furthermore, the second number of times may be sent to the second network-side device (for example, sent to the second network-side device carried in the fourth indication information). In this case, the number of times the second network-side device repeats transmitting the first information may be the second number of times.
[0121] In one embodiment, the second network-side device may determine the number of times for repeating the transmission of the first information according to the communication quality of communicating with the terminal. For example, the number of times for repeating the transmission of the first information may be negatively correlated with the communication quality. For example, the second network-side device may determine the number of times for repeating the transmission of the first information according to the frequency-domain resources configured for the terminal. For example, the number of times for repeating the transmission of the first information may be negatively correlated with the frequency-domain resources configured for the terminal.
[0122] In one embodiment, on the basis of receiving the second number of times, the second network-side device may further receive the first communication quality when the first network-side device repeats transmitting the first information to the terminal sent by the first network-side device. After the terminal switches to the second network-side device, the second communication quality of the second network-side device communicating with the terminal may be determined. Furthermore, the second number of times may be adjusted according to the first communication quality and the second communication quality to determine the number of times the second network-side device repeats transmitting the first information.
[0123] For example, if the second communication quality is greater than the first communication quality, then the second number of times may be reduced and used as the number of times the second network-side device repeats transmitting the first information. For example, if the second communication quality is less than the first communication quality, then the second number of times may be increased and used as the number of times the second network-side device repeats transmitting the first information. For example, if the second communication quality is equal to the first communication quality, then the second number of times may be used as the number of times the second network-side device repeats transmitting the first information.
[0124] In one embodiment, on the basis of receiving the second number of times, the second network-side device may further receive the first frequency-domain resource when the first network-side device repeats transmitting the first information to the terminal. After the terminal switches to the second network-side device, the second frequency-domain resource for communication between the second network-side device and the terminal may be determined. Furthermore, the second number of times may be adjusted according to the first frequency-domain resource and the second frequency-domain resource to determine the number of times the second network-side device repeats transmitting the first information.
[0125] For example, if the second frequency-domain resource is greater than the first frequency-domain resource, the second number of times may be reduced and used as the number of times the second network-side device repeats transmitting the first information; for example, if the second frequency-domain resource is less than the first frequency-domain resource, the second number of times may be increased and used as the number of times the second network-side device repeats transmitting the first information; for example, if the second frequency-domain resource is equal to the first frequency-domain resource, the second number of times may be used as the number of times the second network-side device repeats transmitting the first information.
[0126] In one embodiment, the fourth indication information is further used to indicate the HPN corresponding to the first information to the second network-side device.
[0127] In one embodiment, the first network-side device may perform repeated transmission of the first information on a HARQ process, and the HPN of the HARQ process where the repeated transmission of the first information is located can be determined for the first network-side device and the terminal.
[0128] When the first network-side device determines that the terminal needs to switch to the second network-side device, if it is determined that the terminal has not successfully received the first information, the first HPN of the HARQ process where the repeated transmission of the first information is located may be sent to the second network-side device. Furthermore, when the second network-side device repeats transmitting the first information to the terminal, the HPN of the HARQ process used may also be the first HPN.
[0129] When the terminal receives information from the second network-side device, the second HPN of the HARQ process where the received information is located may be determined. When the second HPN is the same as the first HPN, it can be determined that the information sent by the second network-side device is the repeated transmission information, so that the information sent by the second network-side device can be received as the repeated transmission of the first information. Accordingly, it can be accurately determined which information sent by the second network-side device is the repeated transmission of the first information, and then it is ensured to successfully decode and obtain the first information.
[0130] In one embodiment, the method further includes:
[0131] Sending second indication information to the terminal;
[0132] Among them, the second indication information is used to indicate at least one of the following:
[0133] The duration from the current time to the service end time of the satellite currently being served, the service start time of the satellite, and the service duration.
[0134] In one embodiment, the first network-side device can indicate the duration from the current time to the service end time of the satellite currently being served by sending the second indication information to the terminal. Among them, the second indication information is carried in at least one of the following: Radio Resource Control (RRC) signaling, Medium Access Control layer Control Element (MAC CE), and Physical layer signaling.
[0135] In one embodiment, the first network-side device can directly indicate to the terminal the duration from the current time to the service end time of the satellite currently being served through the second indication information;
[0136] In one embodiment, the first network-side device can indicate the service start time and service duration of the satellite through the second indication information. The terminal can determine the duration from the current time to the service end time of the satellite currently being served according to the service start time and service duration of the satellite. For example, the terminal can first determine the service end time of the satellite according to the sum of the service start time and service duration of the satellite, and then determine the duration from the current time to the service end time of the satellite currently being served according to the difference between the service end time and the current time.
[0137] It should be noted that the duration from the current time to the service end time of the satellite currently being served can be determined according to the indication of the first network-side device, or can be determined independently by the terminal. For example, the terminal can determine the service end time of the satellite according to the ephemeris information of the satellite's movement, and then determine the duration from the current time to the service end time of the satellite currently being served according to the difference between the service end time and the current time.
[0138] In one embodiment, the method further includes:
[0139] Sending third indication information to the terminal, where the third indication information is used to indicate that the duration from the current time to the service end time of the satellite currently being served is less than a duration threshold.
[0140] In one embodiment, the first network-side device can determine whether the duration from the current time to the service end time of the satellite currently being served is less than the duration threshold. When it is determined that the duration from the current time to the service end time of the satellite currently being served is less than the duration threshold, the first network-side device can send the third indication information to the terminal. Then, when the terminal receives the third indication information sent by the first network-side device, it can determine that the duration from the current time to the service end time of the satellite currently being served is less than the duration threshold.
[0141] Figure 8 It is a schematic flowchart of an information transmission method shown according to an embodiment of the present disclosure. The information transmission method shown in this embodiment can be executed by a second network-side device, and the second network-side device can communicate with a terminal. The second network-side device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices (such as NB-IoT, MTC, eMTC).
[0142] As Figure 8 shown, the information transmission method may include the following steps:
[0143] In step S801, receive the first information and the fourth indication information sent by the first network-side device;
[0144] In step S802, determine to repeatedly transmit the first information to the terminal according to the fourth indication information;
[0145] In step S803, after the terminal switches to the second network-side device, repeatedly transmit the first information to the terminal.
[0146] In one embodiment, when the first network-side device repeatedly transmits the first information to the terminal, if the terminal determines that it needs to switch to the second network-side device, then the terminal can determine whether it has successfully received the first information, and then send the first indication information to the first network-side device. The first network-side device can determine whether the terminal has successfully received the first information according to the first indication information.
[0147] When the first network-side device determines that the terminal has not successfully received the first information according to the first indication information, it can determine the network-side device that the terminal is about to switch to, for example, called the second network-side device, and then send the first information and the fourth indication information to the second network-side device. The second network-side device is instructed to repeatedly transmit the first information to the terminal through the fourth indication information. Then, after the terminal switches to the second network-side device, the second network-side device can repeatedly transmit the first information to the terminal according to the fourth indication information. In this process, the second network-side device repeatedly transmitting the first information to the terminal is equivalent to continuing the incomplete repeated transmission of the first network-side device.
[0148] For example, when the first network-side device and the second network-side device are base stations, the first network-side device can send the first information and the fourth indication information to the second network-side device through the interface between base stations.
[0149] Accordingly, even if the process of the first network-side device retransmitting the first information to the terminal is interrupted, after the terminal switches to the second network-side device, the terminal can receive the retransmitted first information from the second network-side device, and accurately determine the first information based on the first information retransmitted by the first network-side device and the first information retransmitted by the second network-side device.
[0150] In one embodiment, the method further includes:
[0151] Determining the remaining retransmission times of the first information according to the fourth indication information;
[0152] Wherein, the retransmitting the first information to the terminal includes:
[0153] Retransmitting the first information to the terminal according to the remaining retransmission times.
[0154] In one embodiment, the first network-side device can also determine the remaining retransmission times of the first information that needs to be retransmitted to the terminal, and then can also indicate the remaining retransmission times to the second network-side device (for example, carried in the fourth indication information), so that the network-side device can retransmit the first information to the terminal according to the remaining retransmission times, for example, the number of retransmissions is the remaining retransmission times. This avoids the second network-side device retransmitting the first information too few times, resulting in the terminal having difficulty in successfully receiving the first information, and also avoids the second network-side device retransmitting the first information too many times, causing resource waste.
[0155] In one embodiment, for example, when the number of times the first network-side device retransmits the first information is the first number of times, the terminal switches to the second network-side device, and the first number of times is less than the number-of-times threshold (the pre-agreed number of times to retransmit the first information). In this case, if the first network-side determines that the terminal has not successfully received the first information, it can send the first information and the fourth indication information to the second network-side device, and indicate the second network-side device to retransmit the first information to the terminal through the fourth indication information.
[0156] The number of times the second network-side device retransmits the first information can be determined according to the indication of the first network-side device, or can be determined by the second network-side device as needed.
[0157] In one embodiment, the first network-side device determines the remaining retransmission times according to the first number of times the first information has been retransmitted and the number-of-times threshold (for example, determined according to the difference between the number-of-times threshold and the first number of times), for example, referred to as the second number of times, and then can send the second number of times to the second network-side device (for example, sent to the second network-side device carried in the fourth indication information). In this case, the number of times the second network-side device retransmits the first information can be the second number of times.
[0158] In one embodiment, the second network-side device may determine the number of times to retransmit the first information according to the communication quality of communicating with the terminal. For example, the number of times to retransmit the first information may be negatively correlated with the communication quality; for example, the second network-side device may determine the number of times to retransmit the first information according to the frequency-domain resources configured for the terminal. For example, the number of times to retransmit the first information may be negatively correlated with the frequency-domain resources configured for the terminal.
[0159] In one embodiment, on the basis of receiving the second number of times, the second network-side device may further receive the first communication quality when the first network-side device retransmits the first information to the terminal sent by the first network-side device. After the terminal switches to the second network-side device, the second communication quality of the second network-side device communicating with the terminal may be determined. Furthermore, the second number of times may be adjusted according to the first communication quality and the second communication quality to determine the number of times the second network-side device retransmits the first information.
[0160] For example, if the second communication quality is greater than the first communication quality, then the second number of times may be reduced and used as the number of times the second network-side device retransmits the first information; for example, if the second communication quality is less than the first communication quality, then the second number of times may be increased and used as the number of times the second network-side device retransmits the first information; for example, if the second communication quality is equal to the first communication quality, then the second number of times may be used as the number of times the second network-side device retransmits the first information.
[0161] In one embodiment, on the basis of receiving the second number of times, the second network-side device may further receive the first frequency-domain resources when the first network-side device retransmits the first information to the terminal sent by the first network-side device. After the terminal switches to the second network-side device, the second frequency-domain resources of the second network-side device communicating with the terminal may be determined. Furthermore, the second number of times may be adjusted according to the first frequency-domain resources and the second frequency-domain resources to determine the number of times the second network-side device retransmits the first information.
[0162] For example, if the second frequency-domain resources are greater than the first frequency-domain resources, then the second number of times may be reduced and used as the number of times the second network-side device retransmits the first information; for example, if the second frequency-domain resources are less than the first frequency-domain resources, then the second number of times may be increased and used as the number of times the second network-side device retransmits the first information; for example, if the second frequency-domain resources are equal to the first frequency-domain resources, then the second number of times may be used as the number of times the second network-side device retransmits the first information.
[0163] In one embodiment, the method further includes:
[0164] Determining the HPN corresponding to the first information according to the fourth indication information;
[0165] Among them, the repeating transmission of the first information to the terminal includes:
[0166] Repeatingly transmitting the first information to the terminal on the hybrid automatic repeat request (HARQ) process corresponding to the HPN.
[0167] In one embodiment, the first network-side device may perform the repeating transmission of the first information on the HARQ process, and the HPN of the HARQ process where the repeating transmission of the first information is located can be determined for the first network-side device and the terminal.
[0168] When the first network-side device determines that the terminal needs to switch to the second network-side device, if it determines that the terminal has not successfully received the first information, it may send the first HPN of the HARQ process where the repeating transmission of the first information is located to the second network-side device. Furthermore, when the second network-side device repeats the transmission of the first information to the terminal, the HPN of the HARQ process used may also be the first HPN.
[0169] When the terminal receives information from the second network-side device, it can determine the second HPN of the HARQ process where the received information is located. When the second HPN is the same as the first HPN, it can be determined that the information sent by the second network-side device is exactly the repeated transmission information, so that the information sent by the second network-side device can be received as the repeated transmission of the first information. Accordingly, it can be accurately determined which information sent by the second network-side device is the repeated transmission of the first information, and further ensure successful decoding to obtain the first information.
