In conjunction with the accompanying drawings, the technical solution provided in the embodiment of the present application is described in detail through some embodiments and their application scenarios.

As shown in FIG2 , a flow chart of a signal transmission method 200 provided by an exemplary embodiment of the present application is provided. The method may be, but is not limited to, executed by a first device (such as a terminal or a network-side device), and may be specifically executed by hardware and/or software installed in the first device. In this embodiment, the method may at least include the following steps.

S210: The first device feeds back target feedback information according to a target transmission rule.

The target feedback information includes the first feedback information and/or the second feedback information. The first feedback information is obtained by predicting the decodability of the first data. The aforementioned "decodability" can be understood as the prediction of whether the first data can be correctly decoded before the first device decodes the first data. If it can be decoded correctly, the first feedback information obtained can be an ACK signal, and the first device decodes the first data; otherwise, the first feedback information can be a NACK signal to request the sender of the first data (such as the second device) to retransmit the first data, etc., so as to greatly reduce unnecessary decoding and improve transmission efficiency.

Optionally, there may be multiple ways to predict the decodability of the first data. For example, in this embodiment, the decodability of the first data may be predicted based on but not limited to an AI model, and the AI model may be a neural network, a decision tree, a support vector machine, a Bayesian classifier, etc., which is not limited here.

The second feedback information is determined based on the decoding result after decoding the first data. If the first device decodes the first data and the decoding result is successful, the second feedback information is determined to be an ACK signal. Otherwise, the second feedback information is determined to be a NACK signal to request retransmission of the first data, etc.

In this case, for correct feedback of the first feedback information and the second feedback information, the first device The first feedback information and the second feedback information can be transmitted based on the target transmission rule, that is, the present application clearly defines the timing logic and association relationship between the first feedback information and the second feedback information through the target transmission rule, so that the second device as the receiving end of the target feedback information can clearly distinguish the received feedback information, avoid repeated execution or erroneous execution of related operations (such as retransmission of the first data, etc.), and improve the transmission efficiency of the communication system.

Based on this, in this embodiment, the target transmission rule may be configured with at least one of performing or prohibiting decodability prediction, feeding back or prohibiting the first feedback information, and feeding back or prohibiting the second feedback information. Optionally, the target transmission rule may be implemented by a rule agreed upon in a protocol, a pre-configured rule, a high-level configuration, a network-side configuration, etc., which is not limited here.

For example, as a possible implementation, when the target transmission rule is configured through a high-level configuration or a network-side configuration, the target transmission rule can be determined by at least one of the following (11)-(13).

(11) Receiving a first indication, where the first indication is used to instruct the first device to perform or prohibit decodability prediction, that is, the first indication is used to activate or deactivate the decodability prediction function of the first device.

(12) receiving a second indication, where the second indication is used to instruct the first device to feed back or prohibit feeding back the first feedback information, that is, the second indication is used to activate or deactivate a function of the first device to feed back the first feedback information.

(13) receiving a third indication, where the third indication is used to instruct the first device to feed back or prohibit feeding back the second feedback information, that is, the third indication is used to activate or deactivate a function of the first device feeding back the second feedback information.

The first indication, the second indication, and the third indication mentioned above can be sent by the second device, and they can be transmitted based on the same signaling or different signaling. In addition, when the first indication, the second indication, and the third indication perform the aforementioned information indication, they can adopt an explicit or implicit indication method, which is not limited here.

It should be noted that no matter how the target transmission rule is configured, it is necessary to ensure that the first device and the second device have consistent understanding of the target transmission rule, so that the second device as the receiving end of the target feedback information can clearly distinguish the received feedback information.

In this embodiment, the first device feeds back target feedback information according to the target transmission rule, the target feedback information includes first feedback information and/or second feedback information, the first feedback information is obtained by predicting the decodability of the first data, the second feedback information is determined according to a decoding result after decoding the first data, and the target transmission rule is configured with at least one of performing or prohibiting decodability prediction, feeding back or prohibiting the first feedback information from being fed back, and feeding back or prohibiting the second feedback information from being fed back, thereby enabling a receiving end of the target feedback information to effectively distinguish the received feedback signal, thereby improving the transmission efficiency of the communication system.

As shown in Figure 3, it is a flow chart of a signal transmission method 300 provided by an exemplary embodiment of the present application, and the method can be, but is not limited to, executed by a first device (such as a terminal or a network side device), and can be specifically executed by hardware and/or software installed in the first device. In this embodiment, the method 300 can at least include the following steps.

S310: The first device feeds back target feedback information according to a target transmission rule.

The target feedback information includes first feedback information and/or second feedback information, wherein the first feedback information is obtained by predicting the decodability of the first data, and the second feedback information is obtained by predicting the decodability of the first data. The decoding result after decoding is determined; the target transmission rule is configured with at least one of performing or prohibiting decodability prediction, feeding back or prohibiting the first feedback information, and feeding back or prohibiting the second feedback information.

It can be understood that in addition to referring to the relevant description in method embodiment 200, the implementation process of S310, as a possible implementation method, may be different depending on the target transmission rule, and the process of the first device feeding back the target feedback information according to the target transmission rule may be different. The following is an explanation of this in combination with Examples 1 to 3, as follows.

Example 1

When the target transmission rule is configured to perform decodability prediction, prohibit feedback of the first feedback information, and allow feedback of the second feedback information, the process of the first device feeding back the target feedback information according to the target transmission rule may include the following method 1 or method 2.

Mode 1: When the first device determines that the first data is decodable by predicting the decodability of the first data, the second feedback information is fed back. That is, when the first device determines that the first data is decodable, it decodes the first data, and determines and feeds back the second feedback information according to the decoding result. If the decoding result is a decoding success, the second feedback information is an ACK signal, and if the decoding result is a decoding failure, the second feedback information is a NACK signal.

Mode 2: When the first device determines that the first data is not decodable by predicting the decodability of the first data, the first device feeds back second feedback information, wherein the second feedback information is a NACK signal. That is, when the first device determines that the first data is not decodable, the first device no longer decodes the first data and directly feeds back the second feedback information, wherein the second feedback information is a NACK signal, thereby avoiding unnecessary decoding operations and improving transmission efficiency.

Correspondingly, for the above-mentioned method 1 and method 2, as the second device at the receiving end of the feedback information, since the second device and the first device have the same understanding of the target transmission rule, when the second device receives the feedback information fed back by the first device, it can be determined that it is the second feedback information. At the same time, if the second feedback information is an ACK signal, then the second device can prepare new transmission data relative to the first data, and if the second feedback information is a NACK signal, then the second device retransmits the first data. The new transmission data can be the same as or different from the first data.

Example 2

When the target transmission rule is configured with performing decodability prediction, feeding back the first feedback information, and prohibiting feeding back the second feedback information, the process of the first device feeding back the target feedback information according to the target transmission rule includes the following method 3 or method 4.

Mode 3: When the first data is determined to be decodable by predicting the decodability of the first data, the first data is decoded and the first feedback information is fed back, wherein the first feedback information is an ACK signal. That is, when the first device determines that the first data is decodable, the first device decodes the first data but does not perform confirmation feedback of the second feedback information.

Mode 4: When the first data is determined to be undecodable by predicting the decodability of the first data, first feedback information is sent, wherein the first feedback information is a NACK signal. When determining that the first data is not decodable, the device feeds back first feedback information and does not decode the first data any more.

Correspondingly, for the aforementioned methods 3 and 4, since the second device and the first device have the same understanding of the target transmission rule, when the second device receives the feedback information fed back by the first device, it can be determined as the first feedback information. At the same time, if the first feedback information is an ACK signal, then the second device determines the second data to be transmitted, and the second data is the new transmission data relative to the first data and is stored in the data buffer area; if the second feedback information is a NACK signal, then the second device can determine the third data to be transmitted and store it in the data buffer area, and the third data is the retransmission data of the first data. Among them, the second data and the first data can be the same or different.

Example 3

In a case where the target transmission rule is configured with performing decodability prediction, feeding back the first feedback information, and feeding back the second feedback information, the first device performs decodability prediction on the first data, determines first feedback information according to the prediction result and feeds it back, and decodes the first data, determines the second feedback information according to the decoding result and feeds it back, wherein the feedback time of the first feedback information is earlier than the feedback time of the second feedback information, thereby ensuring the validity of the first feedback information.

Correspondingly, since the second device and the first device have the same understanding of the target transmission rule, when the second device receives feedback information from the first device, it can be determined that the feedback information with an earlier feedback time is the first feedback information, and the feedback information with a later feedback time is the second feedback information.

Based on this, if the second device receives the first feedback information and the second feedback information (ie, the target feedback information includes the first feedback information and the second feedback information), at least one of the following methods 5 to 8 may be executed.

Mode 5: When both the first feedback information and the second feedback information are ACK signals, the second device sends the second data. The second data is determined by the second device when receiving the first feedback information (ACK signal), and the second data is new data relative to the first data.

Mode 6: When the first feedback information is a NACK signal and the second feedback information is an ACK signal, the second device determines fourth data to be transmitted, and the fourth data is a new transmission relative to the first data. Optionally, if the third data has been determined, the third data is released, wherein the third data is determined by the second device when the first feedback information (NACK signal) is received, and the third data is retransmission data of the first data.

Mode 7: When the first feedback information is an ACK signal and the second feedback information is a NACK signal, the second device determines fifth data to be transmitted, and the fifth data is retransmission data of the first data. Optionally, if the second data has been determined, the second data is released, wherein the second data is determined by the second device when receiving the first feedback information (ACK signal), and the second data is new transmission data relative to the first data.

Mode 8: When the target feedback information includes the first feedback information and the second feedback information, and both the first feedback information and the second feedback information are NACK signals, the third data is sent. The second data is determined by the second device when receiving the first feedback information (ACK signal), and the second data is new transmission data relative to the first data.

For the aforementioned methods 5 to 8, it can be understood that if the first device is allowed to feed back the first feedback information and the second feedback information, the second device can determine subsequent operations based on the received first feedback information and the second feedback, so as to further avoid repeated execution or erroneous execution of related operations and improve the transmission efficiency of the communication system.

In addition, for the newly transmitted data and retransmitted data mentioned in the aforementioned methods 5 to 8, the second device can save the data in the data buffer area after confirmation to facilitate subsequent sending operations, thereby improving the transmission efficiency of the communication system.

Further, for the aforementioned information interaction process between the first device and the second device, the signaling carrying each information may be different depending on the difference between the first device and the second device, which is briefly described below. The content is as follows.
