Description

Technical Field

[0001] The present application relates to the field of wireless communication technologies, and in particular, to an information transmission method, a communication node, a storage medium, and a program product. Background Art

[0002] In the traditional scheduled mode1 communication of 3GPP, the base station schedules information for the transmitting UE, and the transmitting UE transmits direct transfer data to the receiving UE according to the scheduling information. The data receiving UE performs blind detection in the communication resource pool. Further, the data receiving UE feeds back HARQ information to the data transmitting UE. Finally, the data transmitting UE generates HARQ feedback information based on the feedback information reception result and sends it to the base station, and then the entire data transmission process can end. In an industrial field network, there is a scheduling for direct communication between UEs by a head node UE with strong functions. The head node can send scheduling information to the transmitting UE or to the data receiving UE. In this case, compared with the traditional direct communication scheduling, the blind detection process of the data receiving UE can be reduced. However, there will be a problem that the data transmitting UE and the data receiving UE have inconsistent understandings of the scheduling information, which will further affect the data transmission between communication nodes.

[0046] To make the objectives, technical solutions, and advantages of this application clearer and more understandable, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined arbitrarily with each other.

[0047] The head node in this embodiment is of the UE type and can also be referred to as a control communication node, a control communication node, or a head UE, which will not be distinguished further in this text.

[0048] With the development of wireless communication technology and the increasing communication needs of users, in order to meet the communication requirements of low latency, high reliability, and high data rate, the fifth-generation mobile communication technology (5G), 5G-A, and the sixth-generation mobile communication technology (6G) have become the trends for future network development and implementation. The future communication network includes not only the link from the base station to the UE (Uu link) but also the direct connection link (sidelink) from UE to UE. In sidelink communication of the UE, when there is traffic to be transmitted between user devices (UEs), the traffic data between the UEs does not pass through the network side, that is, it is not forwarded through the cellular link between the UE and the base station, but is directly transmitted from the data source UE to the target UE through the sidelink. In the industrial field network scenario, under the coverage of the base station, there are both direct connection UEs and some remote UEs. The remote UEs are directly connected to the head node UE. Figure 1 A network architecture diagram is provided.

[0049] The small network composed of member UEs and the head node UE can be called a micro network. In the micro network, only the head node needs to be connected to the base station, and other UEs only need to establish a connection with the head node UE to achieve communication between UE and another UE or between UE and the base station. This technology can reduce the burden on the cellular network, reduce the battery power consumption of user equipment, well meet the requirements of high data rate services and proximity services, and also support direct communication between devices in a network coverage-free scenario, and can meet the low latency and high reliability communication requirements in the industrial field network.

[0050] When the traditional base station schedules direct communication between UEs, first the base station sends down the scheduling information, and then the sending UE sends data according to the indication of the scheduling information. Then the receiving UE blindly detects and receives the data information. Next, the receiving UE generates HARQ information according to the data reception result and sends it to the sending UE. Finally, the sending UE sends the HARQ information to the scheduling node. Only then can a data transmission be completed. Figure 2 An implementation example diagram of data transmission is provided.

[0051] In the industrial field network, the head node head UE has certain resource management functions. By following the traditional scheduling and feedback mechanism, the head node can achieve scheduling of UEs. Figure 3 Another implementation example diagram of data transmission is provided, and the process of data transmission and feedback is as Figure 3 .

[0052] The difference between the in - field network and the direct - connection communication in the traditional mode1 is that the scheduling node changes from the base station to the UE. Therefore, there is no need to distinguish between the downlink, uplink, and sidelink anymore. Also, both the transmitting UE and the receiving UE are connected to the control node / head node (in legacy mode 1, only the transmitting UE is guaranteed to be connected to the scheduling node, and there are no requirements for the receiving UE). Additionally, the feedback time in the traditional communication mode is relatively long. Therefore, for the HARQ feedback mechanism, other forms can be reconsidered to achieve a unified design for communication between UEs.

[0053] In a network composed of a head node and multiple member UEs in the industrial in - field network, it can be divided into the following 4 categories according to different grant - receiving UEs of the head node and different HARQ - feedback - receiving UEs:

[0054] Figure 4a An implementation example diagram of data feedback is provided, where the grant is only sent to the data - transmitting UE, and the Rx UE HARQ is only sent to the head - node UE;

[0055] Figure 4b Another implementation example diagram of data feedback is provided, where the grant is only sent to the data - transmitting UE, and the Rx UE HARQ is sent to the head - node UE and the data - transmitting UE;

[0056] Figure 4c Another implementation example diagram of data feedback is provided, where the grant is sent to the data - transmitting UE and the data - receiving UE, and the Rx UE HARQ is only sent to the head - node UE;

[0057] Figure 4d Another implementation example diagram of data feedback is provided, where the grant is sent to the data - transmitting UE and the data - receiving UE, and the Rx UE HARQ is sent to the head - node UE and the data - transmitting UE.

[0058] Among the above four types, the head node can receive feedback information from the data - receiving UE faster, and the overhead of feedback resources on the sidelink is reduced. However, there are also some problems. For example, the data - transmitting UE and the resource - scheduling node Head UE may have inconsistent understandings of the feedback information of the Rx UE, or there may be inconsistent understandings of the scheduling information of the same data between the data - receiving UE and the data - transmitting UE in Figure 4b and 4c which may lead to communication failures. The embodiments of this application further analyze and solve these problems.

[0059] In some embodiments, the control communication node can be the head node, and the member communication nodes can be UEs. The member communication nodes can act as data - sending parties to send data or as data - receiving parties to receive data.

[0060] Figure 5 A flowchart of an information transmission method provided for an embodiment is as follows Figure 5 As shown, the information transmission method described in the embodiments of the present application is applied to a control communication node, and the method includes S110 - S120:

[0061] S110. Receive the first feedback information corresponding to the authorization control information of the member communication node, where the first feedback information indicates the receiving status of the physical transmission resource authorization information of the member communication node.

[0062] Among them, the authorization control information can be understood as information for authorizing and controlling the physical transmission resources of the communication node. For example, it indicates that the member communication node activates the physical transmission resources, or indicates that the member communication node releases (deactivates) the physical transmission resources, etc. The first feedback information can be understood as the information fed back by the member communication node. The first feedback information is used to indicate the receiving status of the physical transmission resource authorization information of the member communication node, and can be used to represent whether the member communication node activates / deactivates the physical transmission resources. The first feedback information can indicate the activation or deactivation of the member communication node resources, and can be an acknowledgment message ACK or a negative acknowledgment message NACK. When the control communication node receives an ACK, it means that the member communication node has successfully received and applied the signaling indicated by the authorization control information. When the control communication node receives an NACK, it means that the member communication node has successfully received but has not used the indicated signaling / or does not execute this signaling. When the control communication node does not receive the first feedback information of the member communication node, it means that the member communication node may not have received the authorization control information. The number of the first feedback information can be one or more. For example, both the member communication node acting as the data receiver and the member communication node acting as the data sender feed back the first feedback information. In this case, the member communication node can receive two first feedback information; or, the member communication node acting as the data receiver does not feed back the first feedback information, and the member communication node acting as the data sender feeds back the first feedback information. In this case, the member communication node can receive one first feedback information; both the member communication node acting as the data receiver and the member communication node acting as the data sender do not feed back the first feedback information. In this case, the number of the first feedback information received by the member communication node is 0.

[0063] After receiving the authorization control information, the member communication node activates or releases the physical transmission resources according to the indication of the authorization control information, and generates first feedback information for corresponding feedback. The control communication node receives the first feedback information corresponding to the authorization control information of one or more member communication nodes, and the first feedback information indicates the receiving status of the physical transmission resource authorization information of the member communication node. The authorization control information can be sent by the control communication node to the member communication node, and the control communication node indicates the scheduling information of the member communication node through the authorization control information. For example, which physical transmission resource is used to transmit data.

[0064] S120. Determine the scheduling control process for the member communication node according to the first feedback information.

[0065] The scheduling control process for the member communication node can be to instruct the member communication node to release resources, re-send the authorization control information to the member communication node, instruct the member communication node to send data, receive data, etc. Analyze the received first feedback information to determine whether each member communication node has made corresponding feedback for the authorization control information and the specific feedback information. For example, the member communication node may not make feedback, or the member communication node can feedback information such as ACK and NACK. Determine how to perform scheduling control on the member communication node according to the analysis result, and perform different scheduling control processes on the member communication node according to different feedback information. For example, according to the first feedback information, it is determined that one member communication node feedbacks NACK and one member communication node feedbacks ACK. In this case, it can be determined that the two member communication nodes have inconsistent understandings of the scheduling information, and the scheduling control process for the member communication node is to control the authorized member communication node to release resources; or, according to the first feedback information, it is determined that one member communication node feedbacks ACK and one member communication node does not feedback. In this case, it can also be determined that the two member communication nodes have inconsistent understandings of the scheduling information, and the scheduling control process for the member communication node is to re-send the authorization control information to the member communication node that has not made feedback, and so on.

[0066] Taking the activation of physical transmission resources as an example, usually, after the control communication node sends authorization scheduling information to the data receiver and two member communication nodes of the data receiver, it will not perform other operations. The member communication nodes activate the physical transmission resources according to the authorization scheduling information, or reject the activation of the physical transmission resources or fail to activate the physical transmission resources. In this case, if the two member communication nodes fail to both activate the physical transmission resources, data cannot be normally transmitted at this time. For example, if the data receiver activates the physical transmission resources and the data sender does not activate the physical transmission resources, in this case, the data receiver waits to receive data, but the data sender will not send data because the resources are not activated, resulting in waste of resources of the data receiver; or, if the data sender activates the physical transmission resources and the data receiver does not activate the physical transmission resources, in this case, the data sender sends data, but the data receiver cannot receive the data because the resources are not activated, resulting in waste of resources of the data sender, and so on. For the two member communication nodes that are respectively the data receiver and the data receiver, the information they feedback cannot simultaneously indicate that both parties have activated the physical transmission resources, and it can be considered that their understandings of the scheduling information are inconsistent.

[0067] In the information transmission method provided by the embodiments of the present application, the control communication node receives the first feedback information corresponding to the authorization control information of the member communication node, and the first feedback information indicates the receiving status of the physical transmission resource authorization information of the member communication node; determines the scheduling control process for the member communication node according to the first feedback information, solves the problem that different member communication nodes have inconsistent understandings of the scheduling information. After the control communication node sends the authorization control information to the member communication node, the member communication node performs authorization control on the physical transmission resources according to the authorization control information and feedbacks the first feedback information, and indicates the receiving status of the physical transmission resource authorization information of the member communication node through the first feedback information; the control communication node determines how to perform scheduling control on the member communication node according to the first feedback information. In the case where the member communication nodes have inconsistent understandings of the scheduling information, precise scheduling control can also be performed on the member communication nodes to avoid the occurrence of abnormal data transmission.

[0068] In some embodiments, in some embodiments, the feedback resource where the first feedback information is located is determined by at least one of the following:

[0069] Authorization control information indication;

[0070] The control channel resource where the authorization control information is located;

[0071] Control communication node identifier;

[0072] Member communication node identifier;

[0073] Feedback resource configuration or pre-configured signaling.

[0074] For example, the authorization control information indicates that the first feedback information is to be fed back via resource x; or, the control channel resource where the authorization control information is located is determined, and resource y is determined through calculation based on the control channel resource in combination with an algorithm or rule, and the first feedback information is fed back via resource y; or, feedback resources are pre-allocated to different control communication nodes and associated with the control communication node identifiers. After receiving the authorization control information, the member communication node determines which control communication node sent this authorization control information, determines the associated feedback resource based on the identifier of this control communication node, and sends the first feedback information based on this feedback resource; or, feedback resources are pre-allocated to different member communication nodes and associated with the member communication node identifiers. After receiving the authorization control information, the member communication node determines the associated feedback resource based on the identifier of this member communication node, and sends the first feedback information based on this feedback resource; or, the feedback resource is pre-configured or indicated by pre-configuration signaling.

[0075] In some embodiments, when the authorization control information instructs the member communication node to activate the physical transmission resource, determining the scheduling control process for the member communication node based on the first feedback information includes at least one of the following:

[0076] For the member communication nodes that are the data sender and the data receiver and have not received feedback information, resend new authorization control information to the member communication node that is the data sender and the member communication node that is the data receiver;

[0077] For the member communication node that is the data sender and has not received feedback information, and for which the member communication node that is the data receiver has sent a negative acknowledgment, resend new authorization control information to the member communication node that is the data sender and the member communication node that is the data receiver;

[0078] For the member communication node that is the data sender and has received a negative acknowledgment, and for the member communication node that is the data receiver and has not received feedback information, resend new authorization control information to the member communication node that is the data sender and the member communication node that is the data receiver;

[0079] For the member communication node that is the data sender and has received an acknowledgment, and for the member communication node that is the data receiver and has not received feedback information, resend new authorization control information to the member communication node that is the data receiver;

[0080] For the member communication node that is the data sender and has received an acknowledgment, for the member communication node that is the data receiver and has not received feedback information and meets the activation condition, resend new authorization control information to the member communication node that is the data receiver;

[0081] Upon receiving the confirmation information fed back by the member communication node of the data recipient and not receiving the feedback information from the member communication node of the data sender, resend the new authorization control information to the member communication node of the data sender;

[0082] Upon receiving the confirmation information fed back by the member communication node of the data recipient, not receiving the feedback information from the member communication node of the data sender and meeting the activation condition, resend the new authorization control information to the member communication node of the data sender;

[0083] Upon receiving the confirmation information fed back by the member communication node of the data sender and receiving the negative confirmation information fed back by the member communication node of the data recipient, send an authorization release signaling to the member communication node of the data sender;

[0084] Upon receiving the confirmation information fed back by the member communication node of the data sender, not receiving the feedback information from the member communication node of the data recipient and not meeting the activation condition, send an authorization release signaling to the member communication node of the data sender;

[0085] Upon receiving the confirmation information fed back by the member communication node of the data recipient and receiving the negative confirmation information fed back by the member communication node of the data sender, send an authorization release signaling to the member communication node of the data recipient;

[0086] Upon receiving the confirmation information fed back by the member communication node of the data recipient, not receiving the feedback information from the member communication node of the data sender and not meeting the activation condition, send an authorization release signaling to the member communication node of the data recipient.

[0087] Among them, the activation condition can be understood as the condition for judging whether to activate the member communication node again, and the activation condition can be set in advance. The authorization release signaling can be understood as the signaling for instructing the member communication node to release the physical transmission resources.

[0088] When the authorization control information instructs the member communication node to activate the physical transmission resources, the scheduling control process for the member communication node includes the following: 1. Resend the new authorization control information to the member communication node of the data sender and the member communication node of the data recipient; 2. Resend the new authorization control information to the member communication node of the data recipient; 3. Resend the new authorization control information to the member communication node of the data sender; 4. Send an authorization release signaling to the member communication node of the data sender; 5. Send a release signaling to the member communication node of the data recipient.

[0089] Determine whether the member communication node of the data recipient and the member node of the data sender activate the physical transmission resources by analyzing the first feedback information, and then select an appropriate scheduling control process to perform scheduling control on the member communication node.

[0090] After analyzing the first feedback information, when the control communication node determines that at least one of the following situations is included, it re - sends new authorization control information to the member communication nodes of the data sender and the member communication nodes of the data receiver:

[0091] No feedback information is received from the member communication nodes of the data sender and the member communication nodes of the data receiver;

[0092] No feedback information is received from the member communication nodes of the data sender, and a negative acknowledgment message is received from the member communication nodes of the data receiver;

[0093] A negative acknowledgment message is received from the member communication nodes of the data sender, and no feedback information is received from the member communication nodes of the data receiver.

[0094] The above situations indicate that no feedback information is received from the member communication nodes of the data sender and the member communication nodes of the data receiver, which means that neither the member communication nodes of the data sender nor the member communication nodes of the data receiver have activated the physical transmission resources. In the case where one member communication node does not give feedback and the other member communication node gives a negative acknowledgment message (i.e., NACK), it means that one member communication node has not activated the physical transmission resources, and the other member communication node refuses to activate this physical transmission resource. In the above situations, new authorization control information is re - sent to the two member communication nodes of the data sender and the data receiver for re - authorization.

[0095] After analyzing the first feedback information, when the control communication node determines that at least one of the following situations is included, it re - sends new authorization control information to the member communication nodes of the data receiver:

[0096] A confirmation message is received from the member communication nodes of the data sender, and no feedback information is received from the member communication nodes of the data receiver;

[0097] A confirmation message is received from the member communication nodes of the data sender, no feedback information is received from the member communication nodes of the data receiver and the activation condition is met.

[0098] The above situation indicates that the confirmation information feedback by the member communication node of the data sender is received, indicating that the member communication node of the data sender has activated the physical transmission resource, while the feedback information of the member communication node of the data receiver is not received, indicating that the member communication node of the data receiver has not activated the physical transmission resource. In this case, a new authorization control information is re-sent to the member communication node of the data receiver to re-authorize the member communication node of the data receiver that has not provided feedback. In the case where the member communication node of the data receiver does not provide feedback, the member communication node of the data receiver can be directly re-authorized, or it can be determined whether the activation condition is met. If the activation condition is met, re-authorization is performed; if the activation condition is not met, no further authorization is performed. The activation condition can be preset according to one or more types of information such as time, the number of activations, and the information of the member communication node; for example, it is preset whether different member communication nodes can be re-activated and saved as the information of the member communication node. When it is determined according to the information of the member communication node that this member communication node cannot be re-activated, it is determined that the activation condition is not met.

[0099] After analyzing the first feedback information, when the control communication node determines that at least one of the following situations is included, it re-sends a new authorization control information to the member communication node of the data sender:

[0100] The confirmation information feedback by the member communication node of the data receiver is received, and the feedback information of the member communication node of the data sender is not received;

[0101] The confirmation information feedback by the member communication node of the data receiver is received, the feedback information of the member communication node of the data sender is not received, and the activation condition is met.

[0102] The above situation indicates that when the confirmation information is received from the member communication node of the data recipient, it means that the member communication node of the data recipient has activated the physical transmission resource. When the feedback information from the member communication node of the data sender is not received, it means that the member communication node of the data sender has not activated the physical transmission resource. In this case, a new authorization control message is re-sent to the member communication node of the data sender, and the member communication node of the data sender that has not provided feedback is re-authorized. When the member communication node of the data sender does not provide feedback, it is possible to directly re-authorize the member communication node of the data sender, or to determine whether the activation conditions are met. If the activation conditions are met, re-authorization is performed; if the activation conditions are not met, authorization is not performed. The activation conditions can be preset according to one or more types of information such as time, the number of activations, and the information of the member communication node. For example, it is preset whether different member communication nodes can be re-activated and saved as the information of the member communication node. When it is determined according to the information of the member communication node that this member communication node cannot be re-activated, it is determined that the activation conditions are not met. When it is determined according to the information of the member communication node that this member communication node can be re-activated, it is determined that the activation conditions are met.

[0103] After analyzing the first feedback information, when the control communication node determines that at least one of the following situations is included, it sends an authorization release signaling to the member communication node of the data sender:

[0104] The confirmation information is received from the member communication node of the data sender, and the negative confirmation information is received from the member communication node of the data recipient;

[0105] The confirmation information is received from the member communication node of the data sender, the feedback information from the member communication node of the data recipient is not received, and the activation conditions are not met.

[0106] The above situation indicates that when the confirmation information is received from the member communication node of the data sender, it means that the member communication node of the data sender has activated the physical transmission resource; when the negative confirmation information is received from the member communication node of the data recipient, it means that the member communication node of the data recipient refuses to activate this physical transmission resource; when the feedback information from the member communication node of the data recipient is not received and the activation conditions are not met, it means that the member communication node of the data recipient has not activated this physical transmission resource and the activation conditions are not met. In the above cases, an authorization release signaling is sent to the member communication node of the data sender, instructing the member communication node of the data sender to release the activated physical transmission resource.

[0107] After analyzing the first feedback information, when the control communication node determines that at least one of the following situations is included, it sends a release signaling to the member communication node of the data recipient:

[0108] Received the acknowledgment information feedback by the member communication node of the data recipient, and received the negative acknowledgment information feedback by the member communication node of the data sender;

[0109] Received the acknowledgment information feedback by the member communication node of the data recipient, did not receive the feedback information of the member communication node of the data sender and did not meet the activation condition.

[0110] The above situations indicate that receiving the acknowledgment information feedback by the member communication node of the data recipient means that the member communication node of the data recipient has activated the physical transmission resource; receiving the negative acknowledgment information feedback by the member communication node of the data sender means that the member communication node of the data sender refuses to activate this physical transmission resource; not receiving the feedback information of the member communication node of the data sender and not meeting the activation condition means that the member communication node of the data sender has not activated this physical transmission resource and does not meet the activation condition. In the above situations, send an authorization release signaling to the member communication node of the data recipient, instructing the member communication node of the data recipient to release the activated physical transmission resource.

[0111] That is, for the member communication node of the data recipient and the member communication node of the data sender, if one of the member communication nodes feedbacks ACK and the other member communication node feedbacks NACK, or, one of the member communication nodes feedbacks ACK and the other member communication node does not feedback and does not meet the activation condition, then send an authorization release signaling to the member communication node that feedbacks ACK, instructing it to release the activated physical transmission resource.

[0112] In some embodiments, the activation condition includes at least one of the following:

[0113] The current time has not reached the end time of the activation validity period of the member communication node of the data sender;

[0114] The current time has not reached the end time of the activation validity period of the member communication node of the data recipient;

[0115] The number of times of sending the authorization control information does not exceed the sending times threshold.

[0116] Among them, the end time of the activation validity period refers to the time limit for activating the physical transmission resources. The physical transmission resources of the member communication nodes can be activated before the end time of the activation validity period. The transmission count threshold can be set in advance. For example, the transmission count threshold is 10. When setting the transmission count threshold, it can be set according to experience or considering factors such as the service scenario. After sending the authorization control information, the transmission count of this authorization control information can be recorded. After re - sending, the transmission count is accumulated and compared with the transmission count threshold to determine whether the activation condition is met. The transmission count threshold limits the number of times the authorization control information is repeatedly sent. For example, the transmission count threshold is 10, which means that the authorization control information can be repeatedly sent 10 times. If it has not been activated after more than 10 times, it will no longer be sent.

[0117] In some embodiments, the end time of the activation validity period is determined according to at least one of the following:

[0118] The data transmission time;

[0119] The system - configured or pre - configured or pre - defined time interval.

[0120] Among them, the data transmission time can be understood as the time when the member communication node sends data. For example, the member communication node of the data sender needs to send data to the member communication node of the data receiver, and the time of sending the data is the data transmission time. This data transmission time can be indicated by the control communication node or determined by the member communication node of the data sender. The end time of the activation validity period can be determined according to any one of the data transmission time and the time interval. For example, the data transmission time is used as the end time of the activation validity period; or, the sending time of the authorization control information is recorded, and this time plus the time interval is used as the end time of the activation validity period; or, the data transmission time plus the time interval is used as the end time of the activation validity period, and so on. Among them, the time interval can be system - configured or pre - configured or pre - defined.

[0121] In some embodiments, the time - frequency position of the physical transmission resources indicated by the re - sent authorization control information is the same as the time - frequency position of the physical transmission resources indicated by the already - sent authorization control information after the time slot of the re - sent authorization control information.

[0122] For example, after the control communication node sends the authorization activation information, the data sending UE is successfully activated, but the data receiving UE is not successfully activated. The time-frequency resource position of the first transmission of the physical transmission resource indicated by the sent authorization control information is in slot3, with a period of 100. The member communication node of the data sending UE can send data in slot3, slot103, slot203... If the authorization control information re-sent to the data receiving UE is sent after slot3, for example, in slot50, at this time, after receiving this authorization control information, in order to ensure that the data receiving party and the data sending party have a consistent understanding of the authorization activation information so that the data can be received normally, the time-frequency resource position of the first transmission of the physical transmission resource indicated by the authorization control information re-sent to the member communication node of the data receiving UE is in slot 103, with a period of 100. In this way, the data receiving UE waits to receive periodic data in slots such as slot103 and slot203 after slot 50, that is, the time-frequency position of the physical transmission resource indicated by the re-sent authorization control information is the same as that of the physical transmission resource indicated by the sent authorization control information after slot50.

[0123] In some embodiments, upon receiving the negative acknowledgment information fed back by the member communication nodes of the data sending party and the data receiving party, new authorization control information is sent to the member communication nodes of the data sending party and the data receiving party to activate new physical transmission resources.

[0124] That is, upon receiving the negative acknowledgment information fed back by the member communication nodes of the data sending party and the data receiving party, it means that both the member communication node of the data sending party and the member communication node of the data receiving party reject to activate the physical transmission resource indicated by it, and new authorization control information is sent to activate new physical transmission resources.

[0125] In some embodiments, in the case where the authorization control information instructs the member communication node to release the physical transmission resource, determining the scheduling control process for the member communication node according to the first feedback information includes:

[0126] In the case where it is determined according to the first feedback information that at least one of the member communication nodes of the data sending party and the data receiving party has not fed back, the authorization control information is re-sent to the member communication node that has not fed back.

[0127] When the authorization control information instructs a member communication node to release physical transmission resources, analyze the first feedback information to determine the feedback from the member communication node of the data sender and the member communication node of the data receiver. The feedback of the member communication node can be no feedback or feedback confirmation information. Among them, the confirmation information indicates that the member communication node releases the physical transmission resources, that is, the deactivation is successful; no feedback indicates that the member communication node does not release the physical transmission resources, that is, the deactivation fails. When at least one of the member communication nodes of the data sender and the member communication node of the data receiver does not give feedback, re - send the authorization control information to the member communication node that does not give feedback, instructing the member communication node that does not give feedback to release the physical transmission resources again, that is, re - deactivate.

[0128] The information transmission method provided in the embodiments of the present application controls a communication node to receive the first feedback information corresponding to the authorization control information of a member communication node. The authorization control information can instruct the member communication node to activate physical transmission resources or instruct the member communication node to release physical transmission resources; analyze the first feedback information to determine whether the feedback from the member communication node is received, and whether the feedback is confirmation information or negative confirmation information in the case of receiving feedback, so as to determine which member communication node to schedule and the scheduling control process of the member communication node, solve the problem that different member communication nodes have inconsistent understandings of scheduling information. After the communication node sends the authorization control information to the member communication node, the member communication node activates or releases the physical transmission resources according to the authorization control information and feeds back the first feedback information, and the first feedback information indicates the reception status of the physical transmission resource authorization information of the member communication node; control the communication node to determine how to perform scheduling control on the member communication node according to the first feedback information. In the case where the member communication nodes have inconsistent understandings of the scheduling information, precise scheduling control can also be performed on the member communication nodes to avoid abnormal data transmission; the scheduling of the member communication node includes re - sending the authorization control information and sending an authorization release instruction, avoiding resource waste of the member communication node and ensuring normal data transmission between member communication nodes.

[0129] Figure 6 For the flowchart of another information transmission method provided in an embodiment, as Figure 6 shown, the information transmission method described in the embodiments of the present application is applied to a member communication node, and this method includes S210 - S220:

[0130] S210. Receive authorization control information.

[0131] Receive authorization control information, which can be sent by a control communication node. A member communication node can receive the authorization control information through a predefined resource; the member communication node can be a member communication node of a data receiver or a data sender, that is, the member communication node can act as both a data receiver and a data sender.

[0132] S220. Send a first feedback message according to the authorization control information, where the first feedback message indicates the receiving status of the physical transmission resource authorization information of the member communication node.

[0133] After receiving the authorization control information, activate or release (i.e., deactivate) the physical transmission resource according to the indication of the authorization control information, determine the first feedback message and perform corresponding feedback. The member communication node can indicate the receiving status of the physical transmission resource authorization information of this member communication node through the first feedback message. For example, the first feedback message is ACK or NACK. By ACK, it indicates that the member communication node has successfully received and applied the signaling indicated by the authorization control information. For example, the member communication node activates the physical transmission resource. By NACK, it indicates that the member communication node has successfully received but has not used the indicated signaling. For example, the member communication node refuses to activate the physical transmission resource, or the member communication node does not send the first feedback message, that is, does not perform feedback. The control communication node analyzes according to the first feedback messages received from each member communication node, and determines the scheduling control process for the member communication node according to the first feedback message.

[0134] In the information transmission method provided by the embodiments of the present application, the member communication node receives the authorization control information and sends a first feedback message according to the authorization control information, where the first feedback message indicates the receiving status of the physical transmission resource authorization information of the member communication node, which solves the problem that different member communication nodes have inconsistent understandings of scheduling information; after the control communication node sends the authorization control information to the member communication node, the member communication node activates the physical transmission resource authorization according to the authorization control information and feeds back the first feedback message, and indicates the receiving status of the physical transmission resource authorization information of the member communication node through the first feedback message; so that the control communication node can determine how to perform scheduling control on the member communication node according to the first feedback message, and can also perform precise scheduling control on the member communication node in the case of inconsistent understandings of scheduling information by the member communication nodes, avoiding data transmission anomalies.

[0135] In some embodiments, the authorization control information includes: a physical transmission resource authorization activation signaling or a physical transmission resource authorization release signaling;

[0136] The physical transmission resource authorization activation signaling is used to instruct the member communication node to activate at least one set of physical transmission resources;

[0137] The physical transmission resource authorization release signaling is used to instruct a member communication node to release the activated physical transmission resources.

[0138] In some embodiments, the feedback resource where the first feedback information is located is determined by at least one of the following:

[0139] The authorization control information indication;

[0140] The control channel resource where the authorization control information is located;

[0141] The control communication node identifier;

[0142] The member communication node identifier;

[0143] The feedback resource configuration or pre-configuration signaling.

[0144] Figure 7 A flowchart of another information transmission method provided for an embodiment is as Figure 7 shown. The information transmission method described in the embodiments of the present application is applied to a member communication node, and the method includes S310 - S330:

[0145] S310. Send the first data.

[0146] Among them, the first data can be understood as the data transmitted by the member communication node and can be data of any type of service. The member communication node can send the first data as the data sender to other member communication nodes, and the other member communication nodes act as the data receivers to receive the first data.

[0147] S320. After sending the first data, receive the first information corresponding to the first data.

[0148] Among them, the first information can be the feedback information of the first data, or control information, scheduling information, etc. generated according to the reception situation of the first data, or multiple types of the above information; among them, the reception situation of the first data can be determined according to the feedback information of the first data, that is, the first information is information related to the feedback of the first data. The first data can be sent by the control communication node or by the member communication node of the data receiver.

[0149] After receiving the first data, the member communication node of the data recipient can determine whether the received first data is correct and send a first message to the member communication node of the data recipient, indicating whether the received first data is correct or indicating the data processing procedure required by the member communication node of the data recipient through the first message; alternatively, after receiving the first data, the member communication node of the data recipient determines whether the received first data is correct and sends feedback information to the control communication node. The control communication node generates a first message based on the feedback information and sends the first message to the member communication node of the data sender, indicating the data processing procedure required by the member communication node of the data recipient through the first message.

[0150] S330. Perform corresponding data processing according to the first message corresponding to the first data.

[0151] After receiving the first message corresponding to the first data, the member communication node determines the data processing procedure by analyzing the first message and further performs corresponding data processing. The data processing procedure may be to retransmit the first data, clear the first data, etc.; for example, if it is determined according to the first message that the first data received by the member communication node of the data recipient is incorrect or abnormal data, the first data is retransmitted; or, if it is determined according to the first message that the first data received by the member communication node of the data recipient is correct data, the first data is cleared.

[0152] In the information transmission method provided by the embodiments of the present application, the member communication node sends the first data, receives the first message corresponding to the first data, and performs corresponding data processing according to the first message corresponding to the first data, solving the problem that different member communication nodes have inconsistent understandings of the feedback information. According to the first message corresponding to the first data, corresponding processing can be performed on the first data in the case of inconsistent understanding of the feedback information of the first data, avoiding data processing errors or unclear situations of how to process the data.

[0153] In some embodiments, the first message includes at least one of the following:

[0154] Data retransmission scheduling information sent by the control communication node;

[0155] Second feedback information sent by the data receiving node.

[0156] Among them, the data retransmission scheduling information may be Hybrid Automatic Repeat reQuest (HARQ), which is used to indicate the retransmission of data. The second feedback information is a type of feedback information that can be used to indicate whether the first data is correctly received. For example, when the second feedback information is ACK, it means that the first data received by the data receiving node is correct; when the second feedback information is NACK, it means that the first data received by the data receiving node is incorrect. The data receiving node may be a member communication node acting as the data receiver.

[0157] In some embodiments, the first information includes data retransmission scheduling information. Corresponding data processing is performed according to the first information corresponding to the first data, including:

[0158] If the data retransmission scheduling information corresponding to the first data is received within the set time range, the first data is retransmitted according to the indication of the data retransmission scheduling information;

[0159] If the data retransmission scheduling information corresponding to the first data is not received within the set time range, the data retransmission buffer in the data process corresponding to the first data is cleared.

[0160] Among them, the set time range can be understood as a period of time range, which can be set in advance. For example, it can be 10 ms.

[0161] The first information includes data retransmission scheduling information, indicating that when the member communication node performs corresponding data processing, only the data retransmission scheduling information is considered. It is judged whether the data retransmission scheduling information corresponding to the first data is received within the set time range. If the data retransmission scheduling information corresponding to the first data is received, the first data is retransmitted according to the indication of the data retransmission scheduling information; if the data retransmission scheduling information corresponding to the first data is not received, it means that the first data does not need to be retransmitted, and the data retransmission buffer in the data process corresponding to the first data is cleared.

[0162] The above set time range can be denoted as the first set time range, that is, the first information includes data retransmission scheduling information. Corresponding data processing is performed according to the first information, including: if the data retransmission scheduling information corresponding to the first data is received within the first set time range, the first data is retransmitted according to the indication of the data retransmission scheduling information; if the data retransmission scheduling information corresponding to the first data is not received within the first set time range, the data retransmission buffer in the data process corresponding to the first data is cleared.

[0163] In some embodiments, the first information includes: data retransmission scheduling information and second feedback information. Corresponding data processing is performed according to the first information corresponding to the first data, including:

[0164] Receive the second feedback information corresponding to the first data, and perform corresponding data processing according to the data retransmission scheduling information and the information indicated by the second feedback information;

[0165] If the second feedback information corresponding to the first data is not received, perform corresponding data processing according to the data retransmission scheduling information.

[0166] The first information includes data retransmission scheduling information and second feedback information, indicating that the member communication node considers both the data retransmission scheduling information and the second feedback information when performing corresponding data processing. The second feedback information can indicate whether the data receiving node correctly receives the first data. For example, the second feedback information is ACK or NACK. If the member communication node receives the second feedback information corresponding to the first data, it comprehensively considers the data retransmission scheduling information and the second feedback information, determines the data processing process according to whether the data retransmission scheduling information is received and analyzes the information indicated by the second feedback information, and then performs corresponding data processing. If the member communication node does not receive the second feedback information corresponding to the first data, it determines the data processing process only according to the data retransmission scheduling information and performs corresponding data processing; when performing corresponding data processing according to the data retransmission scheduling information, it can determine whether the data retransmission scheduling information is received, and different data processing can be performed in different situations.

[0167] In some embodiments, performing corresponding data processing according to the data retransmission scheduling information and the information indicated by the second feedback information includes:

[0168] If the second feedback information is an acknowledgment message, clear the data retransmission buffer in the data process corresponding to the first data;

[0169] After receiving the data retransmission scheduling information, feedback an acknowledgment message.

[0170] In the case of receiving the second feedback information corresponding to the first data, analyze the information specifically indicated by the second feedback information. For example, the second feedback information is an acknowledgment message (or the second feedback information indicates an acknowledgment message), or the second feedback information is a negative acknowledgment message (or the second feedback information indicates a negative acknowledgment message). If the second feedback information is an acknowledgment message, it means that the data receiving party indicates to this member communication node that the first data it received is correct, and clear the data retransmission buffer in the data process corresponding to the first data; after receiving the data retransmission scheduling information, the member communication node feedbacks an acknowledgment message, and can indicate that the data receiving node has correctly received the first data through the acknowledgment message.

[0171] In some embodiments, performing corresponding data processing according to the data retransmission scheduling information and the information indicated by the second feedback information includes:

[0172] The second feedback information is an acknowledgement message and the data retransmission scheduling information is received within the set time range, and the retransmission of the first data is performed according to the indication of the data retransmission scheduling information;

[0173] The second feedback information is an acknowledgement message and the data retransmission scheduling information is not received within the set time range, and the data retransmission buffer in the data process corresponding to the first data is cleared.

[0174] When the second feedback information corresponding to the first data is received, analyze the information specifically indicated by the second feedback information. If the second feedback information is an acknowledgement message, determine whether the data retransmission scheduling information is received within the set time range. If the data retransmission scheduling information is received, perform the retransmission of the first data according to the indication of the data retransmission scheduling information; if the data retransmission scheduling information is not received, it means that the first data does not need to be retransmitted, and the data retransmission buffer in the data process corresponding to the first data is cleared.

[0175] Exemplarily, a member communication node sends the first data to a data receiving node. After receiving the first data, the data receiving node sends the second feedback information of ACK to both the member communication node and the control communication node. After receiving the second feedback information of ACK, the control communication node does not need to send the data retransmission scheduling information to the member control node. Since the member control node does not receive the data retransmission scheduling information within the set time range, the data retransmission buffer in the data process corresponding to the first data is cleared. Or, a member communication node sends the first data to a data receiving node. After receiving the first data, the data receiving node sends the second feedback information of ACK to the member communication node and sends the feedback information of NACK to the control communication node. At this time, the feedback understandings of the control communication node and the member communication node for the first data are inconsistent. After receiving the feedback information of NACK, the control communication node generates and sends the data retransmission scheduling information to the member control node. Since the member control node receives the data retransmission scheduling information within the set time range, the retransmission of the first data is performed according to the indication of the data retransmission scheduling information.

[0176] In some embodiments, corresponding data processing is performed according to the information indicated by the data retransmission scheduling information and the second feedback information, including:

[0177] The second feedback information is a negative acknowledgement message and the data retransmission scheduling information is received within the set time range, and the retransmission of the first data is performed according to the indication of the data retransmission scheduling information;

[0178] The second feedback information is a negative acknowledgement message and the data retransmission scheduling information is not received within the set time range, and the data retransmission buffer in the data process corresponding to the first data is cleared, or a retransmission resource is requested.

[0179] In the case of receiving the second feedback information corresponding to the first data, if the second feedback information is a negative acknowledgment message, determine whether the data retransmission scheduling information is received within the set time range. If the data retransmission scheduling information is received, retransmit the first data according to the indication of the data retransmission scheduling information; if the data retransmission scheduling information is not received, clear the data retransmission buffer in the data process corresponding to the first data. In this case, it can be considered that there is no need to retransmit the first data; or, if the data retransmission scheduling information is not received, request retransmission resources to retransmit the first data, further ensuring that the data received by the data receiving node is correct.

[0180] Exemplarily, the member communication node sends the first data to the data receiving node. After receiving the first data, the data receiving node sends the second feedback information of NACK to both the member communication node and the control communication node. After receiving the second feedback information of NACK, the control communication node generates the data retransmission scheduling information and sends it to the member control node. After receiving the data retransmission scheduling information within the set time range, the member control node retransmits the first data according to the indication of the data retransmission scheduling information. Or, the member communication node sends the first data to the data receiving node. After receiving the first data, the data receiving node sends the second feedback information of NACK to the member communication node and sends the feedback information of ACK to the control communication node. At this time, the control communication node and the member communication node have inconsistent understandings of the feedback of the first data. After receiving the feedback information of ACK, the control communication node does not need to send the data retransmission scheduling information to the member control node. If the member control node does not receive the data retransmission scheduling information within the set time range, it clears the data retransmission buffer in the data process corresponding to the first data, or requests retransmission resources.

[0181] In some embodiments, performing corresponding data processing according to the data retransmission scheduling information includes:

[0182] Receiving the data retransmission scheduling information within the set time range and retransmitting the first data according to the indication of the data retransmission scheduling information;

[0183] Not receiving the data retransmission scheduling information within the set time range, clearing the data retransmission buffer in the data process corresponding to the first data, or requesting retransmission resources.

[0184] In the case where the second feedback information corresponding to the first data is not received, it is determined whether data retransmission scheduling information is received within a set time range. If the data retransmission scheduling information is received, the first data is retransmitted according to the indication of the data retransmission scheduling information; if the data retransmission scheduling information is not received, the data retransmission buffer in the data process corresponding to the first data is cleared, and in this case, it can be considered that there is no need to retransmit the first data; or, if the data retransmission scheduling information is not received, a retransmission resource is requested to retransmit the first data.

[0185] In the case where the first information includes data retransmission scheduling information and second feedback information, the set time range in this case is denoted as the second set time range, that is:

[0186] Corresponding data processing is performed according to the information indicated by the data retransmission scheduling information and the second feedback information, including: when the second feedback information is an acknowledgment message and the data retransmission scheduling information is received within the second set time range, the first data is retransmitted according to the indication of the data retransmission scheduling information; when the second feedback information is an acknowledgment message and the data retransmission scheduling information is not received within the second set time range, the data retransmission buffer in the data process corresponding to the first data is cleared.

[0187] Corresponding data processing is performed according to the information indicated by the data retransmission scheduling information and the second feedback information, including: when the second feedback information is a negative acknowledgment message and the data retransmission scheduling information is received within the second set time range, the first data is retransmitted according to the indication of the data retransmission scheduling information; when the second feedback information is a negative acknowledgment message and the data retransmission scheduling information is not received within the second set time range, the data retransmission buffer in the data process corresponding to the first data is cleared, or a retransmission resource is requested.

[0188] Corresponding data processing is performed according to the data retransmission scheduling information, including: when the data retransmission scheduling information is received within the second set time range, the first data is retransmitted according to the indication of the data retransmission scheduling information; when the data retransmission scheduling information is not received within the second set time range, the data retransmission buffer in the data process corresponding to the first data is cleared, or a retransmission resource is requested.

[0189] The second set time range and the second set time range may be different time ranges.

[0190] In some embodiments, the set time range is determined according to at least one of the following methods:

[0191] Time window;

[0192] Timer.

[0193] After sending the first data, the member communication node can determine a time window and determine a set time range based on this time window. Alternatively, a timer can be preset, and the set time range can be determined based on the timer. For example, the member communication node can start the timer in the time slot when the first data is sent, or can start the timer in the next time slot after sending the first data, and so on.

[0194] In some embodiments, the time window is determined based on at least one of the following information:

[0195] The transmission time slot of the first data;

[0196] The time slot where the feedback resource corresponding to the first data is located;

[0197] The window length.

[0198] In some embodiments, the timer is determined based on at least one of the following information:

[0199] The timer start time determined according to the transmission time slot of the first data;

[0200] The timer start time determined according to the time slot where the feedback resource corresponding to the first data is located;

[0201] The timer duration.

[0202] In some embodiments, the method further includes:

[0203] Before the timer expires, if data retransmission scheduling information is received, control the timer to stop timing.

[0204] In the information transmission method provided by the embodiments of the present application, the member communication node sends the first data and receives the first information corresponding to the first data. The first information can be at least one of the data retransmission scheduling information sent by the control communication node and the second feedback information sent by the data receiving node. By analyzing the data retransmission scheduling information and the second feedback information, it is judged whether the member communication node and the control communication node have the same understanding of the feedback of the first data, and corresponding data processing is performed, so as to solve the problem that different member communication nodes have inconsistent understandings of the feedback information. According to the first information corresponding to the first data, corresponding data processing is performed. In the case of inconsistent understanding of the feedback information of the first data, operations such as retransmitting the first data, clearing the data retransmission buffer, and requesting retransmission resources can be performed, so as to correctly process the first data and avoid data processing errors or unclear situations of how to process the data.

[0205] The information transmission process is described through the following embodiments:

[0206] Embodiment 1

[0207] Taking the member communication node as the UE and the control communication node as the head node UE as an example, the information transmission process is described. In the following description, the data receiving UE can be the member communication node of the data receiver, and the data sending UE can be the member communication node of the data sender.

[0208] The HARQ of the data of the data receiving UE is only sent to the head node UE. The behavior of the data sending UE:

[0209] In Figure 4a Or in the 4c mode, after the data sending UE sends data (for example, the first data) to the data receiving UE according to the scheduling information of the head node, it determines that within a time window, if the data sending UE receives the data retransmission scheduling of the head node within the time window, the data sending UE re-sends the data to the data receiving UE according to the scheduling instruction; otherwise, the data sending UE clears the HARQ buffer in the corresponding process.

[0210] Or,

[0211] In Figure 4a Or in the 4c mode, in the time slot when the data sending UE sends data to the data receiving UE according to the scheduling information of the head node; or, in the next time slot after the time slot when the data sending UE sends data to the data receiving UE according to the scheduling information of the head node, a timer is started. If the data sending UE receives the data retransmission scheduling of the head node before the timer expires, the data sending UE stops the counter and re-sends the data to the data receiving UE according to the scheduling instruction, otherwise the data sending UE clears the HARQ buffer in the corresponding process.

[0212] Or,

[0213] In Figure 4a Or in the 4c mode, the data sending UE sends data to the data receiving UE according to the scheduling information of the head node, and a timer is started in the time slot corresponding to the feedback resource of the data of the data receiving UE indicated by the scheduling information; or, a timer is started in the next time slot after the time slot corresponding to the feedback resource of the data of the data receiving UE indicated by the scheduling information. If the data sending UE receives the data retransmission scheduling of the head node before the timer expires, the data sending UE stops the counter and re-sends the data to the data receiving UE according to the scheduling instruction, otherwise the data sending UE clears the HARQ buffer in the corresponding process.

[0214] Among them, the time window, or the timer is a configured or pre-configured or predefined value. The start time is the first slot after sending the data or the first slot after the time slot where the data receiving UE feeds back information.

[0215] Embodiment 2

[0216] Taking the member communication node as the UE and the control communication node as the head node UE as an example, the information transmission process is described. In the following description, the data receiving UE can be the member communication node of the data receiving party, and the data sending UE can be the member communication node of the data sending party.

[0217] The HARQ of the Rx UE (data receiving UE) is sent to the head node UE and the data transmitting UE. The behavior of the data sending UE is as follows:

[0218] In Figure 4b or Figure 4d mode, after the data sending UE sends data to the data receiving UE according to the scheduling information of the head node, it can receive the feedback from the data receiving UE. At this time, the behavior of the data sending UE can be of two types:

[0219] The first behavior: Without considering the feedback information received from the data receiving UE, only considering the scheduling of the head node UE. Therefore, after the data sending UE sends data, within a time window or within a timer, if it receives the retransmission scheduling of the head node, the data sending UE re-sends the data to the data receiving UE according to the scheduling instruction; otherwise, the data sending UE clears the HARQ buffer in the corresponding process. In this case, the behavior of the data sending UE is the same as that of the data sending UE in Embodiment 1.

[0220] Among them, the time window or the timer is a configured or pre-configured or predefined value. The start time is the first slot after sending the data or the first slot or the next slot after the time slot where the feedback information of the data receiving UE is located.

[0221] The second behavior: Considering the received feedback information. At this time, the behavior of the data sending UE is as follows: After the data sending UE sends data and receives an ACK, it clears the HARQ buffer in the corresponding process. If it then receives the retransmission scheduling of the head node, the data sending UE does not re-send the data and directly sends an ACK to the head node UE;

[0222] Or after the data sending UE sends data and receives an ACK, if it does not receive the retransmission scheduling of the head node within a time window after receiving the ACK, the data sending UE clears the HARQ buffer in the corresponding process; otherwise, the data sending UE re-sends the data according to the retransmission scheduling information of the head node.

[0223] The time window can be at least one of the following:

[0224] The duration of +N ms starting from the end position of the time slot when the ack is received;

[0225] The end position of the time slot when the ACK is received + the duration of N slots;

[0226] The time slot when the ACK is received starts a timer, and the length of the timer is N slots.

[0227] If the data - sending UE sends data and then receives a NACK, the following actions are performed:

[0228] If a re - transmission schedule from the head node is received within a time window, the data is re - sent according to the schedule information; otherwise, the data - sending UE clears the HARQ buffer in the corresponding process;

[0229] Or, if a re - transmission schedule from the head node is received within a time window, the data is re - sent according to the schedule information; otherwise, the data - sending UE requests re - transmission resources from the head node again;

[0230] Or, start a timer. If a re - transmission schedule from the head node is received before the timer expires, the data is re - sent according to the schedule information; otherwise, the data - sending UE clears the HARQ buffer in the corresponding process;

[0231] Or, start a timer. If a re - transmission schedule from the head node is received before the timer expires, the data is re - sent according to the schedule information; otherwise, the data - sending UE requests re - transmission resources from the head node again.

[0232] In some embodiments, the data - sending UE can use the above - mentioned first behavior or second behavior for data transmission according to configuration, pre - configuration, pre - definition, or dynamic indication.

[0233] Embodiment 3

[0234] Taking the member communication node as the UE and the control communication node as the head - node UE as an example, the information transmission process is described. In the following description, the data - receiving UE can be the member communication node of the data - receiving party, and the data - sending UE can be the member communication node of the data - sending party. The grant can be authorization control information.

[0235] The head - node UE sends the grant to the data - sending UE and the data - receiving UE.

[0236] For Figure 4c and Figure 4dIn such a scenario, it is also necessary to consider the problem that the data sending UE and the data receiving UE may have inconsistent understandings of the same grant. For example, when the head node sends an active grant of the second type of configured grant (Configured Grant Type 2, CGtype2) to the data sending UE and the data receiving UE, if the head node UE receives a NACK feedback corresponding to the data of the data receiving UE, at this time, the head node does not know whether the CG of the data sending UE is not activated, or the data sending UE is activated but the data receiving UE fails to decode correctly. This embodiment can solve this problem.

[0237] For the activation of CG type 2:

[0238] 1. For the data sending UE, when receiving the CG type2 scheduling activation information (e.g., grant) from the head node, the data sending UE first feeds back an ACK message to the head node according to the indication of the control information. Further, after feeding back the ACK, it notifies the head node UE that the previous CG becomes effective, and the data sending UE sends data according to the indication of the CG.

[0239] 2. For the data receiving UE, when receiving the CG type2 scheduling activation information, the data receiving UE first feeds back an ACK message to the head node according to the indication of the control information. Further, after feeding back the ACK, it notifies the head node UE that the previous CG becomes effective, and the data receiving UE receives data according to the indication of the CG.

[0240] 3. For the head node UE, when the data sending UE requests CG type2, it sends the CG type2 activation grant to the data sending UE and the data receiving UE according to the request, and receives the feedback information of the data sending UE and the data receiving UE at the position of the feedback resource corresponding to the grant indicated by the scheduling activation information;

[0241] When receiving two ACKs, it indicates that the CG type2 at both the data sending UE and the data receiving UE has been activated;

[0242] When receiving the ACK feedback from the data sending UE and not receiving the feedback from the data receiving UE, it can be considered that the data receiving UE fails to activate successfully. Then, before data transmission, the scheduling activation information is sent to the data receiving UE again. If it fails to activate after the timeout, the head node sends a CG type 2 release command to the data sending party. Among them, the CG resource information indicated by the rescheduled activation information is the same as the previously indicated resource after the time slot of the rescheduled activation information; the CG release command also includes a feedback resource indication, which is used to feedback to the head node UE whether the release is successful.

[0243] When the data - sending UE feedbacks ACK and the data - receiving UE does not feedback, it can be considered that the data - receiving UE fails to activate successfully. Then, before reaching the maximum activation times, the scheduling activation information is sent to the data - receiving UE again. If it still fails to activate successfully, the head node sends a CG type 2 release command to the data - sending UE. Among them, the CG resource information indicated by the rescheduled activation information is the same as the previously indicated resource after the time slot of the rescheduled activation information.

[0244] When the data - sending UE feedbacks ACK and the data - receiving UE does not feedback, it can be considered that the data - receiving UE fails to activate successfully. Then, the scheduling activation information is sent to the data - receiving UE again until it activates successfully (there is no activation time limit here). The CG resource information indicated by the rescheduled activation information is the same as the previously indicated resource after the time slot of the rescheduled activation information.

[0245] When the data - receiving UE feedbacks ACK and the data - sending UE does not feedback, it can be considered that the data - sending UE fails to activate successfully. Then, before data transmission, the scheduling activation information is sent to the data - sending UE again. If it fails to activate after a timeout, the head node sends a CG type 2 release command to the data - receiving UE. Among them, the CG resource information indicated by the rescheduled activation information is the same as the previously indicated resource after the time slot of the rescheduled activation information; the CG release command contains a feedback resource indication, which is used to feedback to the head - node UE whether the release is successful.

[0246] When the data - receiving UE feedbacks ACK and the data - sending UE does not feedback, it can be considered that the data - sending UE fails to activate successfully. Then, before reaching the maximum activation times, the scheduling activation information is sent to the data - sending UE again. If it still fails to activate, the head node sends a CG type 2 release command to the data - receiving UE. Among them, the CG resource information indicated by the rescheduled activation information is the same as the previously indicated resource after the time slot of the rescheduled activation information.

[0247] When the data - receiving UE feedbacks ACK and the data - sending UE does not feedback, it can be considered that the data - sending UE fails to activate successfully. Then, the scheduling activation information is sent to the data - sending UE again until it activates successfully. Among them, the CG resource information indicated by the rescheduled activation information is the same as the previously indicated resource after the time slot of the rescheduled activation information.

[0248] When the head node does not receive the feedback information corresponding to any scheduling activation information, it means that neither the data - sending UE nor the data - receiving UE is activated. The head node resends the scheduling activation information to both UEs.

[0249] When the head node receives NACKs in the feedbacks for the scheduling activation information respectively sent back by the data - sending UE and the data - receiving UE, it indicates that both the data - sending UE and the data - receiving UE reject this scheduling activation information. The head node re - sends the scheduling activation information to the dual - end UE to activate a new CG resource.

[0250] When the head node receives one NACK and one ACK in the feedbacks for the scheduling activation information respectively sent back by the data - sending UE and the data - receiving UE, it indicates that at least one of the data - sending UE and the data - receiving UE rejects this scheduling activation information. The head node sends a release command to the UE that sent the ACK to activate the previous CG resource, and re - sends the scheduling activation information to the dual - end UE to activate a new CG resource.

[0251] In some embodiments, the scheduling activation information instructs the member communication node to activate the physical transmission resource, and the authorization control information can be the scheduling activation information.

[0252] For CG type2 release:

[0253] 1. For the data - sending UE, after receiving the CG type2 de - activation control information from the head node, the data - sending UE first sends an ACK message to the head node according to the indication of the control information. Further, after sending the ACK, it indicates that the previous CG release has taken effect, and stops data transmission according to the indication.

[0254] 2. For the data - receiving UE, after receiving the CG type2 de - activation control information from the head node, the data - receiving UE first sends an ACK message to the head node according to the indication of the control information. Further, after sending the ACK, it indicates that the previous CG de - activation has taken effect, and stops data reception according to the indication of the CG.

[0255] 3. For the head - node UE, after sending the CG type2 de - activation control information (e.g., release signaling) to the data - sending UE and the data - receiving UE, it receives the feedback information from the data - sending UE and the data - receiving UE at the position indicated by the control information;

[0256] When receiving two ACKs, it indicates that the CG type2 at both the data - sending UE and the data - receiving UE has been de - activated successfully.

[0257] When the data - sending UE receives a feedback ACK and does not receive a feedback from the data - receiving UE, it can be considered that the data - receiving UE has not been successfully deactivated. Then, the deactivation control information is sent to the data - receiving UE again. Among them, the CG process information indicated by the deactivation control information sent again is the same as the previous process information. -- When the data - receiving UE receives a feedback ACK and does not receive a feedback from the data - sending UE, it can be considered that the data - sending UE has not been successfully deactivated. Then, the deactivation control information is sent to the data - sending UE again; among them, the CG process information indicated by the deactivation control information sent again is the same as the previous process information.

[0258] When the head - node does not receive any feedback information corresponding to the activation command, it means that neither the data - sending UE nor the data - receiving UE has been successfully deactivated. The head - node resends the deactivation control information to both UEs. Among them, the CG resource process indicated by the deactivation control information sent again is the same as the previous process information.

[0259] In some embodiments, the deactivation control information instructs the member communication node to release the physical transmission resources; the authorization control information can be the deactivation control information or the activation control information. Among them, the deactivation control information can also be the deactivation control signaling, the deactivation control command, or the release signaling, etc.

[0261] The following Figure 4a Or in the mode of 4c, the behavior of the data - sending UE is described by way of example.

[0262] Example 1: No re - transmission scheduling is received before the timer expires

[0263] On slotn, the data - sending UE A sends a scheduling request message to the head - node UE. The scheduling request message contains service characteristic information and the ID of the data - receiving UE B.

[0264] On Slot n + t1, the head - node UE sends scheduling information SCI to the data - sending UE A and the data - receiving UE. The scheduling information indicates the time - frequency position of the data resource that the data - sending UE A is going to send. The data resource is located in slot n + t2 in the time domain, and the position of the corresponding feedback resource for the data. The feedback resource is located in slot n + t3. According to the system - configured delay D, the data - receiving UE starts to count the timer D at slot n + t3. Before the counting ends, the data - sending UE does not receive the re - transmission scheduling. The data - sending UE considers that the data has been successfully received. At this time, the data - sending UE clears the HARQ buffer in the corresponding process. Figure 8 An example diagram of information transmission is provided.

[0265] Example 2: Retransmission scheduling received before the timer expires

[0266] On slot n, the data - sending UE A sends a scheduling request message to the head - node UE. This scheduling request message contains service characteristic information and the ID of the data - receiving UE B.

[0267] On slot n + t1, the head - node UE sends a scheduling information SCI to the data - sending UE A and the data - receiving UE.

The data resource is located in the time domain at slot n + t2, and the position of the corresponding feedback resource for this data. The feedback resource is located in slot n + t3. According to the system - configured delay D, the data - receiving UE starts counting the timer D at the beginning of slot n + t3. Before the counting ends, the data - sending UE receives a re - transmission scheduling. The data - sending UE considers that the data has not been successfully received. At this time, the data - sending UE stops the counter and re - sends the data according to the scheduling information in time slot n + t4. Figure 9 Another example diagram of information transmission is provided.

[0268] Embodiment 5

[0269] Next, for Figure 4b or Figure 4d in the mode, the behavior of the data - sending UE is described by way of example.

[0270] Example 1: The data - sending UE does not consider the feedback information of the data - receiving UE to itself. At this time, the behavior of the data - sending UE is the same as that in Embodiment 4, which will not be elaborated here.

[0271] Example 2: The data - sending UE considers the feedback information of the data - receiving UE to itself and receives an ACK feedback message.

[0272] On slot n, the data - sending UE A sends a scheduling request message to the head - node UE. This scheduling request message contains service characteristic information and the ID of the data - receiving UE B.

[0273] On slot n + t1, the head - node UE sends a scheduling information SCI to the data - sending UE A and the data - receiving UE. This scheduling information indicates the time - frequency position of the data resource that the data - sending UE A is going to send. The data resource is located in the time domain at slot n + t2, and the position of the corresponding feedback resource for this data. The feedback resource is located in slot n + t3. The data - sending UE receives the ACK message sent by the data - receiving UE in slot n + t3. The data - sending UE clears the HARQ buffer in the corresponding process. Figure 10 Another example diagram of information transmission is provided.

[0274] In some embodiments, if the data - sending UE receives a re - transmission scheduling for data in slot n + t4, and the scheduling information indicates the time - domain position n + t5 of the feedback resource, then the data - sending UE sends an ACK message on the feedback resource at slot n + t5 to the head - node UE. Figure 11 Another example diagram of information transmission is provided.

[0275] Example 3: The data - sending UE considers the feedback information of the data - receiving UE to itself, and receives a NACK feedback message or does not receive any feedback message.

[0276] On slot n, the data - sending UE A sends a scheduling request message to the head - node UE. The scheduling request message contains service characteristic information and the ID of the data - receiving UE B.

[0277] At slot n + t1, the head - node UE sends a scheduling information SCI to the data - sending UE A and the data - receiving UE. The scheduling information indicates the time - frequency position of the data resource that the data - sending UE A is going to send. The data resource is located in slot n + t2 in the time - domain, and the position of the corresponding feedback resource for the data. The feedback resource is located in slot n + t3. If the data - sending UE receives a NACK feedback at slot n + t3, then the data - sending UE starts timer 2. If it receives a re - transmission scheduling in slot n + t4 within the timer, then the data - sending UE re - transmits the data according to the scheduling information at slot n + t5.

The data resource is located in slot n + t2 in the time - domain, and the position of the corresponding feedback resource for the data. The feedback resource is located in slot n + t3. If the data - sending UE receives a NACK feedback at slot n + t3, then the data - sending UE starts timer 2. If it does not receive a re - transmission scheduling before the timer ends, then the data - sending UE sends a re - transmission scheduling request to the head - node at slot n + t4. Figure 13 Another example diagram of information transmission is provided.

[0281] Or if no retransmission scheduling is received before the timer expires, the data - sending UE clears the HARQ buffer corresponding to the data process after the timer expires. Figure 14 Another example diagram of information transmission is provided.

The data resources are in the time domain at slot n + t3, and the position of the feedback resources corresponding to the scheduling activation signaling. The feedback resources are in slot n + t2. If the data - sending UE receives the scheduling activation signaling in time slot n + t1, the data - sending UE sends an ACK message to the head - node in time slot n + t2. Figure 15 Another example diagram of information transmission is provided.

[0286] Embodiment 7

[0287] The following gives an example description of the behavior of the data - receiving UE after receiving a semi - static data transmission scheduling activation signaling.

[0288] On slot n, the data - receiving UE B receives the semi - static data transmission scheduling activation signaling sent by the head - node UE. The scheduling information indicates the time - frequency position of the data resources that the data - sending UE A is going to send. The data resources are in the time domain at slot n + t2, and the position of the feedback resources corresponding to the scheduling activation signaling. The feedback resources are in slot n + t1. Then the data - sending UE sends an ACK message to the head - node in time slot n + t1. Figure 16 Another example diagram of information transmission is provided.

[0289] Embodiment 8

[0290] The following gives an example description of the behavior of the head - node after receiving a semi - static transmission request.

[0291] Example 1: After sending the semi - static activation signaling, the head - node receives the ACK message from the data - sending UE and the ACK message from the data - receiving UE.

[0292] The upper node of slot n receives the semi-static scheduling request information sent by the data-sending UE A. This scheduling request information includes service characteristic information and the ID of the data-receiving UE B.

[0293] At time slot slot n+t1, the upper node sends semi-static scheduling activation signaling to the data-sending UE and the data-receiving UE, and indicates the feedback resources corresponding to the activation signaling at time slot n+t2.

[0294] At time slot slot n+t2, the upper node UE respectively receives the ACK feedback information of the data-sending UE and the data-receiving UE regarding the semi-static scheduling activation signaling. Then the upper node confirms that the semi-static transmissions at the data-sending UE and the data-receiving UE are both successfully activated. Figure 17 Another example diagram of information transmission is provided.

[0295] Example 2: After the upper node sends the semi-static activation signaling, it does not receive the feedback information of the data-sending UE and the data-receiving UE regarding the activation signaling.

[0296] The upper node of slot n receives the semi-static scheduling request information sent by the data-sending UE A. This scheduling request information includes service characteristic information and the ID of the data-receiving UE B.

[0297] At time slot slot n+t1, the upper node sends semi-static scheduling activation signaling to the data-sending UE and the data-receiving UE, and indicates the feedback resources corresponding to the activation signaling at time slot n+t2.

[0298] At time slot slot n+t2, the upper node UE does not receive the feedback information of the data-sending UE and the data-receiving UE regarding the activation signaling. Then the upper node confirms that the semi-static transmissions at the data-sending UE and the data-receiving UE are both not successfully activated.

[0299] The upper node UE re-sends the semi-static scheduling activation signaling to the data-sending UE and the data-receiving UE at time slot slot n+t3. Figure 18 Another example diagram of information transmission is provided.

[0300] Example 3-1: After the upper node sends the semi-static activation signaling, it receives the ACK information of the data-sending UE and does not receive the feedback information of the data-receiving UE.

[0301] The upper node of slot n receives the semi-static scheduling request information sent by the data-sending UE A. This scheduling request information includes service characteristic information and the ID of the data-receiving UE B.

[0302] In time slot slot n+t1, the head node sends semi-static scheduling activation signaling to the data sending UE and the data receiving UE, and indicates the feedback resources corresponding to the activation signaling in time slot n+t2, as well as the data transmission resources at time n+t4.

[0303] In time slot slot n+t2, if the head node UE receives the ACK feedback information sent by the data sending UE and does not receive the feedback information of the data receiving UE regarding the activation signaling, then the head node confirms that the activation of the data sending UE is successful, and the semi-static transmission at the data receiving UE is not successfully activated.

[0304] The head node UE re-sends the semi-static scheduling activation signaling to the data receiving UE in time slot slot n+t3 until the data receiving UE feeds back the ACK corresponding to the semi-static scheduling activation signaling and does not exceed time n+t4. In this example, a time interval gap (gap>=0) is determined according to configuration or pre-configuration or predefined rules. If the head node UE does not receive the ACK feedback corresponding to the semi-static scheduling activation signaling from the data receiving UE before n+t4-gap, then this semi-static transmission activation fails, and the head node no longer sends the semi-static scheduling activation signaling to the data receiving UE. The head node sends the semi-static scheduling release signaling to the data sending UE at time n+t5 until the release is successful. Optionally, the head node re-sends the semi-static scheduling activation signaling to the data sending UE and the data receiving UE at time n+t6. Figure 19 Another example diagram of information transmission is provided.

[0305] Example 3-2: After the head node sends the semi-static activation signaling, it receives the ACK information of the data sending UE and does not receive the feedback information of the data receiving UE.

[0306] At time slot n, the head node receives the semi-static scheduling request information of data sending UE A. This scheduling request information includes service characteristic information and the ID of data receiving UE B.

[0307] In time slot slot n+t1, the head node sends semi-static scheduling activation signaling to the data sending UE and the data receiving UE, and indicates the feedback resources corresponding to the activation signaling in time slot n+t2, as well as the data transmission resources at time n+t4.

[0308] In time slot slot n+t2, if the head node UE receives the ACK feedback information sent by the data sending UE and does not receive the feedback information of the data receiving UE regarding the activation signaling, then the head node confirms that the activation of the data sending UE is successful, and the semi-static transmission at the data receiving UE is not successfully activated.

[0309] The head node UE re - issues the semi - static scheduling activation signaling to the data receiving UE at time slot n + t3 until the data receiving UE feeds back the ACK corresponding to the semi - static scheduling activation signaling and does not exceed the time n + t4. In this example, a time interval gap (gap >= 0) is determined according to the configuration or pre - configuration or predefined rules. If the head node UE receives the ACK corresponding to the semi - static scheduling activation signaling from the data receiving UE before n + t4 - gap, then the semi - static transmission activation is successful. Figure 20 Another example diagram of information transmission is provided.

[0310] It should be noted that the data re - transmission scheduling can be data re - transmission scheduling information.

[0311] n, t1, t2, t3, t4, t5, t6, etc. in each embodiment are different and only meaningful within the example, unless otherwise stated as related.

This device is applied to a control communication node, such as Figure 21 As shown, the device includes: a first feedback information receiving module 410 and a scheduling control determination module 420.

[0313] The first feedback information receiving module 410 is used to receive the first feedback information corresponding to the authorization control information of the member communication node, and the first feedback information indicates the receiving status of the physical transmission resource authorization information of the member communication node;

[0314] The scheduling control determination module 420 is used to determine the scheduling control process for the member communication node according to the first feedback information.

After the control communication node sends the authorization control information to the member communication node, the member communication node performs authorization control on the physical transmission resources according to the authorization control information and feeds back the first feedback information, and the first feedback information indicates the receiving status of the physical transmission resource authorization information of the member communication node; the control node determines how to perform scheduling control on the member communication node according to the first feedback information. In the case where the member communication nodes have inconsistent understandings of scheduling information, it is also possible to perform precise scheduling control on the member communication nodes to avoid abnormal data transmission.

[0316] In some embodiments, the feedback resource where the first feedback information is located is determined by at least one of the following:

[0317] Authorization control information indication;

[0318] The control channel resource where the authorization control information is located;

[0319] Controlling communication node identifier;

[0321] Feedback resource configuration or preconfigured signaling.

[0322] In some embodiments, when the authorization control information indicates that a member communication node activates a physical transmission resource, the scheduling control process for the member communication node determined according to the first feedback information includes at least one of the following:

[0323] For a member communication node that has not received feedback information from the data sender and a member communication node that is the data receiver, resend new authorization control information to the member communication node of the data sender and the member communication node of the data receiver;

[0324] For a member communication node that has not received feedback information from the data sender and has received a negative acknowledgment message from the member communication node that is the data receiver, resend new authorization control information to the member communication node of the data sender and the member communication node of the data receiver;

[0325] For a member communication node that has received a negative acknowledgment message from the data sender and has not received feedback information from the member communication node that is the data receiver, resend new authorization control information to the member communication node of the data sender and the member communication node of the data receiver;

[0326] For a member communication node that has received an acknowledgment message from the data sender and has not received feedback information from the member communication node that is the data receiver, resend new authorization control information to the member communication node that is the data receiver;

[0327] For a member communication node that has received an acknowledgment message from the data sender, has not received feedback information from the member communication node that is the data receiver and meets the activation condition, resend new authorization control information to the member communication node that is the data receiver;

[0328] For a member communication node that has received an acknowledgment message from the member communication node that is the data receiver and has not received feedback information from the data sender, resend new authorization control information to the member communication node of the data sender;

[0329] Receiving the confirmation information fed back by the member communication node of the data recipient, not receiving the feedback information from the member communication node of the data sender and meeting the activation conditions, re-sending the new authorization control information to the member communication node of the data sender;

[0330] Receiving the confirmation information fed back by the member communication node of the data sender and receiving the negative confirmation information fed back by the member communication node of the data recipient, sending an authorization release signaling to the member communication node of the data sender;

[0331] Receiving the confirmation information fed back by the member communication node of the data sender, not receiving the feedback information from the member communication node of the data recipient and not meeting the activation conditions, sending an authorization release signaling to the member communication node of the data sender;

[0332] Receiving the confirmation information fed back by the member communication node of the data sender and receiving the negative confirmation information fed back by the member communication node of the data recipient, sending an authorization release signaling to the member communication node of the data recipient;

[0333] Receiving the confirmation information fed back by the member communication node of the data recipient, not receiving the feedback information from the member communication node of the data sender and not meeting the activation conditions, sending an authorization release signaling to the member communication node of the data recipient.

[0334] In some embodiments, the activation conditions include at least one of the following:

[0335] The current time has not reached the end time of the activation validity period of the member communication node of the data sender;

[0336] The current time has not reached the end time of the activation validity period of the member communication node of the data recipient;

[0337] The number of times of sending the authorization control information does not exceed the sending times threshold.

[0338] In some embodiments, the end time of the activation validity period is determined according to at least one of the following:

[0339] The data transmission time;

[0340] The system configuration or pre-configuration or pre-defined time interval.

[0341] In some embodiments, the time-frequency position of the physical transmission resource indicated by the re-sent authorization control information is the same as the time-frequency position of the physical transmission resource indicated by the previously sent authorization control information after the time slot of the re-sent authorization control information.

[0342] In some embodiments, when the authorization control information instructs a member communication node to release physical transmission resources, the process of determining the scheduling control of the member communication node according to the first feedback information includes:

[0343] When it is determined according to the first feedback information that at least one of the member communication nodes of the data sender and the member communication node of the data receiver has not fed back, re - send the authorization control information to the member communication node that has not fed back.

Technical details not described in detail in this embodiment can be referred to in any of the above - mentioned embodiments, and this embodiment has the same beneficial effects as the execution of the information transmission method.
