Fig. 1 is a schematic flowchart of an information receiving method 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 mobile phones, tablet computers, wearable devices, sensors, Internet of Things devices (such as NB-IoT (Narrow Band Internet of Things, Narrow Band Internet of Things) Things), MTC (Machine Type Communication, machine type communication), eMTC (EnhanceMachine Type Communication, enhanced machine type communication)) and other communication devices. The terminal can communicate with network-side equipment, and the network-side equipment includes but is not limited to network-side equipment in communication systems such as 4G, 5G, and 6G, such as base stations and core networks.

As shown in Figure 1, the information receiving method may include the following steps:

In step S101, receiving first information repeatedly transmitted by the first network side device;

In step S102, it is determined that the first information has not been successfully received, and after switching to the second network side device, receiving the first information repeatedly transmitted by the second network side device;

In step S103, the first information is determined according to the first information repeatedly transmitted by the first network side device and the first information repeatedly transmitted by the second network side device.

In one embodiment, the terminal can be a terminal in the non-terrestrial network NTN, and the terminal can communicate with the network-side equipment through air equipment such as satellites, and the satellite can send information sent by the network-side equipment to the terminal, or can send the terminal The sent information is sent to the network side device.

In order 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 may repeatedly transmit the first information to the terminal in order to send the first information to the terminal.

Since the satellite is always in motion in the air, the terminal can receive the first information repeatedly transmitted by the first network side when it is in the coverage of the satellite. When the mobile terminal leaves the coverage of the satellite, it needs to communicate with other satellites. Network-side device communication, in this case, the terminal communicates with the network-side device through other satellites, and may switch to other network-side devices, for example, it is called the second network-side device.

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 It may also be the same network-side device, that is, the terminal communicates with the same network-side device through different satellites. In this case, only the satellite is switched, but the network-side device is not switched.

When the terminal leaves the coverage area of the satellite, if the first information repeatedly transmitted by the first network side device is not successfully received, the repeated transmission will be interrupted. The transmitted first information is decoded, and it is difficult to obtain the first information successfully.

In one embodiment, for example, when the first network-side device repeatedly transmits the first information for the first time, the terminal switches to the second network-side device, and the first time is less than the number of times threshold (pre-agreed repeated transmission number of first messages). 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 through the fourth indication information Repeatedly transmit the first information to the terminal.

The number of times the second network-side device repeatedly transmits the first information may be determined according to an instruction of the first network-side device, or may be determined by the second network-side device as required.

In an embodiment, the first network side device determines the remaining number of repeated transmissions according to the first number of repeated transmissions of the first information and the number threshold (for example, according to the difference between the times threshold and the first number), for example It is called the second number of times, and the second number of times can be sent to the second network side device (for example, carried in the fourth indication information and sent to the second network side device). In this case, the number of times the second network side device repeatedly transmits the first information may be the second number of times.

In an embodiment, the second network-side device may determine the number of repeated transmissions of the first information according to the communication quality with the terminal, for example, the number of repeated transmissions of the first information may be negatively correlated with the communication quality; for example, the second network-side device may The number of repeated transmissions of the first information is determined according to frequency domain resources configured for the terminal, for example, the number of repeated transmissions of the first information may be negatively correlated with the frequency domain resources configured for the terminal.

In an embodiment, on the basis of receiving the second number of times, the second network side device may also receive the first network side device repeatedly transmitting the first information to the terminal sent by the first network side device When the first communication quality. After the terminal is handed over to the second network side device, the second communication quality for the second network side device to communicate 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, so as to determine the number of times the second network side device repeatedly transmits the first information.

For example, the second communication quality is greater than the first communication quality, then the second number of times can be reduced as the number of times the second network side device repeatedly transmits the first information; for example, the second communication quality is less than the first communication quality, then the second number of times can be reduced The increased number is used as the number of times the second network side device repeatedly transmits the first information; for example, the second communication quality is equal to the first communication quality, then the second number can be used as the number of times the second network side device repeatedly transmits the first information.

In an embodiment, on the basis of receiving the second number of times, the second network side device may also receive the first network side device repeatedly transmitting the first information to the terminal sent by the first network side device The first frequency-domain resource at time. After the terminal is handed over 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. Further, the second number of times may be adjusted according to the first frequency domain resource and the second frequency domain resource, so as to determine the number of times the second network side device repeatedly transmits the first information.

For example, the second frequency domain resource is greater than the first frequency domain resource, then the second number of times can be reduced as the number of times the second network side device repeatedly transmits the first information; for example, the second frequency domain resource is smaller than the first frequency domain resource, then it can be Increase the second number of times as the number of times the second network side device repeatedly transmits the first information; for example, the second frequency domain resource is equal to the first frequency domain resource, then the second number of times can be used as the second network side device repeatedly transmits the first information times.

It should be noted that, when the terminal fails to receive the first information, the reason why the terminal needs to switch to the second network side device includes but is not limited to that the terminal is about to leave the coverage of the currently serving satellite.

Fig. 2 is a schematic flowchart of another method for receiving information according to an embodiment of the present disclosure. As shown in FIG. 2, the receiving the first information repeatedly transmitted by the second network side device includes:

In step S201, determine downlink resources according to the scheduling instruction sent by the second network side device;

In step S202, the first information repeatedly transmitted by the second network side device is received on the downlink resource.

In an embodiment, after the terminal is handed over to the second network side device, the second network side device may configure downlink resources for the terminal through scheduling signaling, and then repeatedly transmit the first information to the terminal on the configured downlink resources. Correspondingly, the terminal may also receive the first information repeatedly transmitted by the second network side device on the downlink resources configured by the second network side device.

In an embodiment, the second network side device configures downlink resources for the terminal as required, and repeatedly transmits the first information to the terminal on the downlink resources. For example, the resource when the second network side device is idle can be selected as the downlink resource, so as to prevent the load of the second network side device from being too high; or the resource when the terminal has just switched 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.

In an embodiment, the first network-side device may indicate the downlink resources to the second network-side device, for example, before the terminal switches to the second network-side device, it may send desired information to the first network-side device for indicating After switching to the second network side device, the terminal expects to receive the downlink resource of the first information, and 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 be on the terminal The first information is repeatedly transmitted to the terminal on the expected downlink resource, so as to ensure that the requirement of the terminal is met.

Fig. 3 is a schematic flowchart of another method for receiving information according to an embodiment of the present disclosure. As shown in FIG. 3 , the receiving the first information repeatedly transmitted by the second network side device includes:

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;

In step S302, determine the second HPN corresponding to the HARQ process where the information sent by the second network side device is located;

In step S303, if the second HPN is the same as the first HPN, use the information sent by the second network side device as the first information is received.

In an embodiment, the first network-side device may perform repeated transmission of the first information on the HARQ process, and the HPN of the HARQ process in which the first information is repeatedly transmitted is determinable for the first network-side device and the terminal .

When the terminal determines that it needs to switch to the second network-side device, it can make the first network-side device determine that the terminal will switch to the second network-side device through an instruction. In this case, if the first network side device determines that the terminal fails to receive the first information, it may send the first HPN of the HARQ process where the repeated transmission of the first information is located to the second network side device.

Furthermore, when the second network side device repeatedly transmits the first information to the terminal, the HPN of the HARQ process used may also be the first HPN.

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 belongs, and if the second HPN is the same as the first HPN, it can determine the second HPN sent by the second network side device The information is information that is repeatedly transmitted, so that the information sent by the second network side device can be received as the first information that is repeatedly transmitted. Accordingly, it can be accurately determined which information sent by the two network-side devices is the first information repeatedly transmitted, thereby ensuring that the first information can be successfully decoded and obtained.

Fig. 4 is a schematic flowchart of another method for receiving information according to an embodiment of the present disclosure. As shown in Figure 4, the method also includes:

In step S401, it is determined that the duration from the current time to the service end time of the currently serving satellite is less than the duration threshold;

In step S402, sending first indication information to the first network side device, where the first indication information is used to indicate whether the terminal has successfully received the first information.

In an embodiment, the terminal determines that it needs to switch to the second network side device, which may be determined based on the time length from the current time to the service end time of the currently serving satellite. For example, when the service end time of the currently serving satellite is less than the duration threshold, the terminal may determine that it is about to leave the coverage of the currently serving satellite, and the currently serving satellite is about to stop providing services for the terminal.

In this case, the terminal may send first indication information to the first network side device according to the reception of the first information, and the first network side device may determine whether the terminal has successfully received the first information according to the first indication information. Wherein, the resource for sending the first indication information may be configured by the first network side device, or may be predetermined according to the agreement.

Accordingly, the first network-side device can determine whether the terminal has successfully received the first information according to the first indication information, and then can send the second network-side device to the second network-side device if it is determined that the terminal has not successfully received the first information. One piece of information and fourth indication information, where the fourth indication information is used to instruct the second network side device to repeatedly transmit the first information to the terminal. Therefore, it is ensured that the terminal can receive the first information repeatedly transmitted by the second network-side device after switching to the second network-side device.

Wherein, the first network-side device may also determine the remaining number of repeated transmissions for which the first information needs to be repeatedly transmitted to the terminal, and then may also indicate the remaining number of repeated transmissions to the second network-side device (for example, carried in the fourth indication information), Therefore, the network side device may repeatedly transmit the first information to the terminal according to the remaining number of times of repeated transmission, for example, the number of times of repeated transmission is the remaining number of times of repeated transmission.

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 the first information is repeatedly transmitted to the terminal is less than the number threshold (the number of times the first information is repeatedly transmitted as agreed in advance), there is no need to transmit the first information to the second The network side device sends fourth indication information.

In an embodiment, the situation that the terminal successfully receives the first information includes but is not limited to at least one of the following situations:

The number of times the terminal receives the first network-side device's repeated transmission of the first information has reached a number threshold;

The number of times the terminal receives the first network-side device's repeated transmission of the first information has reached the number threshold, and the terminal decodes the repeatedly received first information, and successfully obtains the first information;

The number of times the terminal receives the first network-side device's repeated transmission of the first information is less than the number of times threshold, but the terminal decodes the repeatedly received first information, and successfully obtains the first information. In this case, the terminal can decode the first information repeatedly received every time it receives the first information repeatedly transmitted for a preset number of times. If the decoding is correct and the first information is complete, it can be determined that the first information has been successfully received, otherwise , it is determined that the first information is successfully received.

In an embodiment, the situation that the terminal fails to receive the first information includes but is not limited to at least one of the following situations:

The number of times the terminal receives the first network-side device's repeated transmission of the first information has reached the number threshold, but the terminal decodes the first information repeatedly received, and fails to obtain the first information;

The number of times the terminal receives the first network-side device's repeated transmission of the first information is less than the number of times threshold;

The number of times the terminal receives the first network-side device's repeated transmission of the first information is less than the number of times threshold, and the terminal decodes the first information repeatedly received, but fails to obtain the first information.

In one embodiment, the method also includes:

When it is determined that the first information has been successfully received, stop receiving the first information that is repeatedly transmitted.

When the terminal has successfully received the first information, it can stop receiving the first information repeatedly transmitted by the first network-side device even if the number of times the first network-side device repeatedly transmits the first information is less than the number of times threshold, so as to avoid waste of 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 repeated transmissions of the first information is less than the number of times threshold, it may stop repeating the transmission of the first information, so as not to waste resources of the first network-side device. waste.

It should be noted that the function of the terminal to actively stop receiving the first information that is repeatedly transmitted may be configured by the network side device. When the terminal is configured to actively stop receiving the first information that is repeatedly transmitted, then when the terminal has completed receiving the first information, even if the number of times the first network side device receives the first information repeatedly transmits the first information is less than the number threshold , will stop receiving the first information repeatedly transmitted by the first network side device; when the unconfigured terminal can actively stop receiving the first information repeatedly transmitted, when the terminal has completed receiving the first information, if If the number of times the first network-side device repeatedly transmits the first information is less than the number of times threshold, the first network-side device will still receive the first information repeatedly transmitted by the first network-side device.

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 currently serving satellite through the second indication information;

In one embodiment, the first network side device may indicate the service start time and service duration of the satellite through the second indication information, and the terminal may determine the current time to The duration of the service end time of the currently serving 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 according to the difference between the service end time and the current time , to determine the duration from the current time to the service end time of the currently serving satellite.

It should be noted that the duration from the current time to the service end time of the currently serving satellite can be determined according to the instruction of the first network side device, or can be determined independently by the terminal. The service end time, and then according to the difference between the service end time and the current time, determine the time length from the current time to the service end time of the currently serving satellite.
