Description
Technical Field
[0001] This disclosure relates to the field of communication technology, and in particular to information transmission methods, devices, storage media and program products. Background Technology
[0002] In wireless communication systems, communication between terminals mainly adopts two modes: Mode 1 and Mode 2. Mode 1 refers to communication between terminals based on transmission resources allocated by network devices; that is, the transmission resources between terminals are allocated by the network devices. Mode 2 refers to communication between terminals based on transmission resources determined by the terminals themselves; that is, the transmission resources between terminals are determined by the terminals themselves from a pre-configured transmission resource pool. However, these two modes are mutually exclusive and cannot simultaneously leverage the advantages of each. For example, in Mode 1, if the local operator's network is overloaded, resulting in untimely or no resource allocation response, normal communication between terminals will be impossible. Summary of the Invention
[0003] This disclosure provides an information transmission method, apparatus, storage medium, and program product that can ensure normal communication between terminals as much as possible, thereby improving the reliability of communication between terminals.
[0004] On one hand, an information transmission method is provided, comprising: sending resource configuration request information to a second node, the resource configuration request information being used to request a first time-frequency resource for communication between a first node and a third node; determining a second time-frequency resource for communication between the first node and the third node based on a pre-configured time-frequency resource pool; communicating with the third node on the first time-frequency resource if a resource configuration response information sent by the second node indicates that the first time-frequency resource is configured; or, communicating with the third node on the second time-frequency resource if a resource configuration response information sent by the second node indicates that the first time-frequency resource is not configured, or if no resource configuration response information is received from the second node.
[0005] In another aspect, an information transmission method is provided, comprising: receiving resource configuration request information from a first node, the resource configuration request information being used to request a first time-frequency resource used for communication between the first node and a third node; sending third information to the third node, the third information being used to instruct the third node to listen on a second time-frequency resource used for communication between the first node and the third node, the second time-frequency resource being determined based on a pre-configured time-frequency resource pool; and sending resource configuration response information to the first node and the third node respectively, the resource configuration response information being used to indicate whether to configure the first time-frequency resource.
[0006] In another aspect, an information transmission method is provided, comprising: receiving third information from a second node, the third information being used to instruct the third node to listen on a second time-frequency resource used for communication between a first node and the third node, the second time-frequency resource being determined based on a pre-configured time-frequency resource pool; the third information being triggered by the second node receiving resource configuration request information, the resource configuration request information being used to request a first time-frequency resource used for communication between the first node and the third node; receiving resource configuration response information from the second node, the resource configuration response information being used to indicate whether to configure the first time-frequency resource used for communication between the first node and the third node; if the resource configuration response information indicates that the first time-frequency resource is configured, communicating with the first node on the first time-frequency resource; or, if the resource configuration response information indicates that the first time-frequency resource is not configured, communicating with the first node on the second time-frequency resource.
[0007] In another aspect, a communication device is provided, comprising: a memory and a processor; the memory and the processor are coupled; the memory is used to store a computer program; and the processor, when executing the computer program, implements the information transmission method of any of the above embodiments.
[0008] In another aspect, a computer-readable storage medium is provided, on which computer program instructions are stored, which, when executed by a processor, implement the information transmission method of any of the above embodiments.
[0009] In another aspect, a computer program product is provided, which includes computer program instructions that, when executed by a processor, implement the information transmission method of any of the above embodiments.
[0010] This disclosure discloses that a first node can send resource configuration request information to a second node, that is, use mode 1 to request the first time-frequency resource used for communication between the first node and the third node, and determine the second time-frequency resource used for communication between the first node and the third node based on the pre-configured time-frequency resource pool, that is, use mode 2 to determine the second time-domain resource.
[0011] If the received resource configuration response information from the second node indicates that the first time-frequency resource is configured, communication with the third node occurs on the first time-frequency resource, i.e., using mode 1. Alternatively, if the received resource configuration response information from the second node indicates that the first time-frequency resource is not configured, or if no resource configuration response information is received from the second node, communication with the third node occurs on the second time-frequency resource, i.e., using mode 2. As can be seen from the above, the first node can adaptively use either the first or second time-frequency resource to communicate with the third node under different circumstances. That is, it can combine modes 1 and 2 to communicate with the third node, thus ensuring normal communication between nodes as much as possible and improving the reliability of communication between nodes.

[0030] With the evolution of fifth-generation mobile communication technology (5G) and the development of future sixth-generation mobile communication technology (6G), the application scenarios for unmanned aerial vehicles (UAVs) are becoming increasingly widespread. Due to their low cost and rapid deployment, UAVs can be applied to various scenarios, including emergency communication services, goods delivery, air quality monitoring, and weather monitoring.
[0031] To ensure the safe integration of drones into the airspace, reliable communication is required between the drones and application servers, and existing communication networks can provide the foundation for this communication.
[0032] With the release of the 3rd Generation Partnership Project (3GPP) Release 18 standard protocol, drones and other flying communication devices have been formally included in the research scope of 5G-A. Currently, the 3GPP Release 18 standard protocol mainly focuses on enhancements to the radio measurement and mobility management of drones and other flying communication devices, so that they can be smoothly and orderly integrated into the networks defined by 3GPP. In current research, drones are mainly divided into UAV terminals and UAV network equipment (or, alternatively, UAV base stations).
[0033] For UAV terminals, since their flight altitude is typically above rooftops or other obstacles, unlike traditional ground terminals, the signal transmission between UAV terminals and network equipment is mostly line-of-sight (LOS). This means there are no obstacles obstructing the network equipment and the UAV terminal, allowing the UAV terminal to receive interference from strong signals from neighboring cells. To address this, 3GPP has modified its terminal measurement strategy by introducing altitude-based measurement reporting triggering capabilities (e.g., events H1 and H2). This strategy helps network equipment understand the current flight altitude range of the UAV terminal. After obtaining the UAV terminal's flight altitude information, the network equipment can optimize parameter configurations to minimize interference from strong signals from surrounding cells. For example, different parameters can be configured for UAV terminals above and below rooftops to optimize communication performance.
[0034] In certain specialized missions, drones typically do not fly solo, but rather in formation from a similar starting point to a similar destination. In this scenario, the drones will follow similar paths and experience similar mobile network coverage environments, but not identical signal transmission environments. Because the drones follow similar paths, their flight pattern can be understood as a formation flight pattern, and they can employ similar configurations, which can save communication and power resources to some extent.
[0035] When a drone's flight altitude exceeds a certain threshold, it can be considered to have entered normal cruise mode, and tall buildings or trees can no longer block the signal. At this point, signal transmission between the drone and network devices, as well as between drones themselves, can be considered as LOS transmission, and the degree of signal attenuation is only related to distance.
[0036] Furthermore, the path loss of the signal during LOS transmission can satisfy the following formula 1:
[0037] L=32.5 + 20lgF+20lgD Formula 1
[0038] Where L is the path loss of the signal during LOS transmission, D is the signal transmission distance, which can be in kilometers (km), and F is the signal frequency, which can be in megahertz (MHz).
[0039] Furthermore, the path loss of signals transmitted by UAV terminals such as drones flying near the ground generally conforms to Formula 1 above. After the signal frequency is determined, the signal transmission distance can be inferred from the path loss; that is, the distance between the receiver and transmitter can be inferred from the information obtained by measuring the signal.
[0040] In the 3GPP technical field, communication between drones is mainly based on PC5 interface sidelink communication technology. Currently, drone communication scenarios are mainly divided into two types: scenarios with operator network coverage and scenarios without operator network coverage.
[0041] In scenarios with carrier network coverage, drones can communicate using mode 1. Specifically, Figure 1 This is a schematic diagram of Mode 1 provided in some embodiments of this disclosure, such as... Figure 1 As shown, the side link transmission resources (or, alternatively, transmission resources based on the PC5 interface) between UAV 1 and UAV 2 are distributed by the network device to UAV 1 and UAV 2 through the Uu interface.
[0042] The communication process of mode1 is explained in detail below. Figure 2 A flowchart of Mode 1 provided for some embodiments of this disclosure, such as Figure 2 As shown, the communication process of mode1 may include the following steps:
[0043] S201, UAV 1 sends resource configuration request information to network device 1.
[0044] Among them, the resource configuration request information is used to request network devices to allocate side-link transmission resources.
[0045] S202, The network device sends resource configuration response information 1 to the drone 1.
[0046] The resource configuration response information includes the sidelink transmission resources allocated by the network device.
[0047] S203, UAV 1 sends resource configuration request information 2 to network device.
[0048] S204. The network device sends resource configuration response information 2 to the drone 1.
[0049] S205. UAV 1 sends a signal to UAV 2 based on the side link transmission resources allocated by the network equipment.
[0050] As mentioned above, in scenarios with carrier network coverage (or in mode 1), communication between drones requires access to sidelink transmission resources authorized by the carrier network, and communication is based on these sidelink transmission resources. In other words, mode 1 requires drones to obtain carrier network-authorized sidelink transmission resources before communicating with each other. This ensures that the sidelink transmission resources allocated by the carrier network do not collide with those used by other drones, but it increases signaling overhead, latency, and power consumption.
[0051] Furthermore, for network-authorized sideLink resources, current solutions pre-set the sub-carrier spacing (SCS), preventing flexible selection of frame structure characteristics for each UAV communication. However, different SCS values determine the use of different time-frequency resources. For example, for the same slot or symbol, a 15kHz SCS uses twice the length of time-domain resources as a 30kHz SCS, but the length of frequency-domain resources used is only 0.5 times that of a 30kHz SCS. Therefore, for delay-sensitive signals, a larger sub-carrier spacing is typically used, while for signals with limited bandwidth, a smaller sub-carrier spacing is usually employed.
[0052] In scenarios without carrier network coverage, drones can communicate using mode 2. Specifically, Figure 3 This is a schematic diagram of Mode 2 provided in some embodiments of this disclosure, such as... Figure 3 As shown, the side link transmission resources between UAV 1 and UAV 2 are determined by the UAVs themselves.
[0053] The communication process of mode2 is explained in detail below. Figure 4 A flowchart of Mode 2 provided for some embodiments of this disclosure, such as Figure 4 As shown, the communication process of mode2 may include the following steps:
[0054] S401 and UAV 1 use a specific algorithm to determine the side link transmission resources from the pre-configured transmission resource pool.
[0055] S402 and UAV 2 are monitoring the side link transmission resources.
[0056] S403, UAV 1 sends a signal to UAV 2 based on the side link transmission resources allocated by the network equipment.
[0057] As mentioned above, in scenarios without carrier network coverage (or in mode 2), UAV 1 needs to use a random algorithm to estimate the sidelink transmission resources used for communication between UAVs and send signals based on these sidelink transmission resources. However, since each UAV uses a random algorithm to determine its sidelink transmission resources, collisions in determining these resources are very likely to occur. This can lead to mutual interference, causing signals to fail to be decoded and thus reducing the reliability of communication.
[0058] In the existing solutions, the two modes mentioned above are mutually exclusive and cannot combine their advantages. Especially for mode 1, when the ground operator's network is overloaded, resulting in untimely or no resource configuration response, information transmitted between drones via the side link (or PC5 interface) cannot be transmitted normally. In this situation, if the drone repeatedly sends resource request information, it will increase the processing burden on the ground operator's network and also consume a lot of the drone's battery power.
[0059] In this regard, the present disclosure discloses that the first node can send resource configuration request information to the second node, that is, use mode 1 to request the first time-frequency resource used by the first node to communicate with the third node, and determine the second time-frequency resource used for communication between the first node and the third node based on the pre-configured time-frequency resource pool, that is, use mode 2 to determine the second time domain resource.
[0060] If the received resource configuration response information from the second node indicates that the first time-frequency resource is configured, communication with the third node occurs on the first time-frequency resource, i.e., using mode 1. Alternatively, if the received resource configuration response information from the second node indicates that the first time-frequency resource is not configured, or if no resource configuration response information is received from the second node, communication with the third node occurs on the second time-frequency resource, i.e., using mode 2. As can be seen from the above, the first node can adaptively use either the first or second time-frequency resource to communicate with the third node under different circumstances. That is, it can combine modes 1 and 2 to communicate with the third node, thus ensuring normal communication between nodes as much as possible and improving the reliability of communication between nodes.
[0061] The information transmission method provided in this disclosure can be applied to systems with various communication standards. For example, the information transmission method provided in this disclosure can be applied to systems including, but not limited to, Long Term Evolution (LTE) systems, various versions based on LTE evolution, 5G systems, future mobile communication networks, or multiple converged communication systems. Furthermore, the information transmission method provided in this disclosure can also be applied to future-oriented communication systems.
[0062] For example, the above information transmission method can be applied to, for example, Figure 5 In communication systems, such as Figure 5 As shown, the communication system includes: a first node 501, a second node 502, and a third node 503.
[0063] The second node 502 can communicate with both the first node 501 and the third node 503. The first node 501 and the third node 503 can be referred to as user equipment (UE), terminal-side equipment, user-side equipment, UAV terminal, etc. The second node 502 can also be referred to as base station-side equipment, network-side equipment, UAV network equipment, etc.
[0064] In some embodiments, the first node 501 may send resource configuration request information to the second node 502, that is, use mode 1 to request the first time-frequency resources used by the first node 501 to communicate with the third node 503, and determine the second time-frequency resources used for communication between the first node 501 and the third node 503 based on the pre-configured time-frequency resource pool, that is, use mode 2 to determine the second time domain resources.
[0065] When the resource configuration response information received from the second node 502 indicates that the first time-frequency resource is configured, the first node 501 communicates with the third node 503 on the first time-frequency resource; or, when the resource configuration response information received from the second node 502 indicates that the first time-frequency resource is not configured, or when no resource configuration response information is received from the second node 502, the first node 501 communicates with the third node 503 on the second time-frequency resource. As can be seen from the above, the first node 501 can adaptively use the first time-frequency resource or the second time-frequency resource to communicate with the third node 503 under different circumstances. That is, it can combine mode 1 and mode 2 to communicate with the third node 503. This can ensure normal communication between nodes as much as possible and improve the reliability of communication between nodes.
[0066] It should be noted that, Figure 5 This is just an example framework diagram. Figure 5 The number of communication devices included, and the names of each communication device, are unlimited, except for... Figure 5 In addition to the communication equipment shown, the communication system may also include other communication equipment, such as relay nodes.
[0067] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.
[0068] The information transmission method provided by the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0069] The information transmission method provided in this disclosure can be applied to... Figure 5 The first node 501 in the communication system shown. Figure 6 A flowchart illustrating an information transmission method is shown, such as... Figure 6 As shown, the information transmission method includes the following steps S601 to S604.
[0070] S601, Send resource configuration request information to the second node.
[0071] Among them, the resource configuration request information is used to request the first time-frequency resource used by the first node to communicate with the third node.
[0072] The time-frequency resources involved in the embodiments of this disclosure include time-domain resources and / or frequency-domain resources, etc., and the embodiments of this disclosure do not limit them.
[0073] In some embodiments, at least one of the first node and the third node is a non-terrestrial terminal, such as a UAV terminal. The second node can be a terrestrial network device or a non-terrestrial network device, such as a UAV network device; this application embodiment does not impose any restrictions on this.
[0074] For example, taking the second node as a network device, if the first node needs to send resource configuration request information to the second node, the first node needs to be in a scenario with operator network coverage.
[0075] In some embodiments, the resource configuration request information includes communication requirements between the first node and the third node, and the communication requirements are used to determine the subcarrier spacing of the first time-frequency resource.
[0076] For example, communication requirements include at least one of the following: latency requirements, throughput requirements, and bit error rate requirements. The above is an exemplary description of communication requirements, and communication requirements may also include other requirements, such as rate requirements, which are not limited in this disclosure.
[0077] For example, taking the aforementioned communication requirements, including latency requirements, as an example, Table 1 shows an example of the correspondence between latency requirements and the subcarrier spacing of the first time-frequency resource. As shown in Table 1, if the aforementioned latency requirement is less than 10 milliseconds (ms), then the subcarrier spacing of the first time-frequency resource is 60 kilohertz (kHz). If the aforementioned latency requirement is greater than or equal to 10 ms and less than 50 ms, then the subcarrier spacing of the first time-frequency resource is 30 kHz. If the aforementioned latency requirement is greater than or equal to 50 ms, then the subcarrier spacing of the first time-frequency resource is 15 kHz.
[0078] Table 1
[0079]
[0080] S602. Determine the second time-frequency resource for communication between the first node and the third node based on the pre-configured time-frequency resource pool.
[0081] In some embodiments, the implementation process of S602 may be as follows: the first node uses a random algorithm to determine the second time-frequency resource for communication between the first node and the third node from the pre-configured time-frequency resource pool.
[0082] In some embodiments provided by this disclosure Figure 6 The information transmission method shown does not restrict the timing of S602. For example, the first node can execute S602 after S601, or after receiving the resource configuration response information, or after receiving the resource configuration response information and before S604.
[0083] S603. When the resource configuration response information received from the second node is used to indicate the configuration of the first time-frequency resource, communication is conducted with the third node on the first time-frequency resource.
[0084] In some embodiments, communicating with a third node as described in this disclosure can be understood as sending signals or data to the third node, or receiving signals or data from the third node, etc. This disclosure does not limit this.
[0085] S604. If the resource configuration response information received from the second node indicates that the first time-frequency resource has not been configured, or if the resource configuration response information received from the second node has not been received, then communicate with the third node on the second time-frequency resource.
[0086] As can be seen from the above, after S601, the second node can send resource configuration response information to the first node and the third node respectively. This resource configuration response information is used to indicate whether to configure the first time-frequency resource.
[0087] Furthermore, in some embodiments, when the resource configuration response information is used to indicate the configuration of the first time-frequency resource, the resource configuration response information includes the configuration information of the first time-frequency resource, which includes the subcarrier spacing of the first time-frequency resource and the time-frequency resource range of the first time-frequency resource.
[0088] In some embodiments, the second node evaluates communication requirements to determine the configuration information of the first time-frequency resource, such as the subcarrier spacing and the time-frequency resource range of the first time-frequency resource. Specifically, the second node can determine the subcarrier spacing of the first time-frequency resource based on latency requirements, and determine the time-frequency resource range of the first time-frequency resource based on the subcarrier spacing of the first time-frequency resource. For example, assuming the second node determines that frequency domain resource 1 corresponding to time domain resource 1 can meet the communication requirements of the subcarrier spacing of the first time-frequency resource, then the time-frequency resource composed of time domain resource 1 and frequency domain resource 1 is determined as the first time-frequency resource.
[0089] For example, Table 2 shows an example of the configuration information for the first time-frequency resource. As shown in Table 2, assuming the subcarrier spacing of the first time-frequency resource is 15kHz, the range of the first time-domain resource can be [t1, t2], and the range of the first frequency-domain resource can be [f1, f2]. Assuming the subcarrier spacing of the first time-frequency resource is 30kHz, the range of the first time-domain resource can also be [t1, t2], and the range of the first frequency-domain resource can also be [f1, f2].
[0090] Table 2
[0091]
[0092] Furthermore, different subcarrier intervals correspond to different lengths of time-frequency resources. For example, Figure 7 Example diagram of a time-frequency resource provided for some embodiments of this disclosure, such as Figure 7As shown, assuming a subcarrier spacing of 30kHz, this corresponds to time-frequency resource 1 and time-frequency resource 2; assuming a subcarrier spacing of 15kHz, this corresponds to time-frequency resource 3 and time-frequency resource 4. Furthermore, time-frequency resources 1 to 4 can all be located within the same time-frequency resource range, and under the same communication requirements with the same subcarrier spacing, the time-frequency resources configured for different nodes do not overlap.
[0093] In one possible implementation, assuming the subcarrier spacing (e.g., 15kHz) used by the first or third node during current communication differs from the subcarrier spacing (e.g., 30kHz) of the first time-frequency resource, the first or third node can immediately switch the subcarrier spacing used by the underlying radio frequency module and processing module to the subcarrier spacing of the first time-frequency resource (e.g., 30kHz). In this case, the first node can transmit data to the third node on the first time-frequency resource, and the third node can receive data from the first node on the first time-frequency resource and process the data based on the subcarrier spacing of the first time-frequency resource.
[0094] Furthermore, if the resource configuration response information does not include the configuration information of the first time-frequency resource, or if the configuration information of the first time-frequency resource does not include the subcarrier spacing of the first time-frequency resource, the subcarrier spacing used by the first node and the second node during communication is determined in advance through negotiation between the first node and the second node; that is, the subcarrier spacing is preset. In this case, the first node can repeatedly send data several times on the second time-frequency resource according to a specific transmission period to ensure that the data can be transmitted normally. The third node can correctly decode the data from the first node based on the preset subcarrier spacing and send an acknowledgment (ACK) message back to the first node. After this, the third node can stop monitoring the second time-frequency resource. After receiving the ACK message, the first node can also stop monitoring the second time-frequency resource.
[0095] For example, taking the second node as a network device, if the first node and the third node need to obtain resource configuration response information from the second node, then both the first node and the third node need to be in a scenario with operator network coverage.
[0096] In some embodiments, combined with Figure 6 ,like Figure 8 As shown, after S603 above, the method provided in this disclosure embodiment further includes:
[0097] S801. If the first node does not receive feedback information sent by the third node on the first time-frequency resource, or receives negative response feedback information on the first time-frequency resource, it communicates with the third node on the second time-frequency resource.
[0098] In some embodiments, feedback information is used to indicate whether the third node has received the signal sent by the first node, while negative response feedback information is used to indicate that the third node has not received the signal sent by the first node.
[0099] Furthermore, in step S801, the signal or data transmitted by the first node to the third node on the second time-frequency resource may be the same as (e.g., retransmitted signal or data) or different from the signal or data transmitted by the first node to the third node on the first time-frequency resource in step S603 above. This disclosure embodiment does not impose any restrictions on this.
[0100] S802, when the first node receives a positive response from the third node on the first time-frequency resource, it stops monitoring the second time-frequency resource.
[0101] In some embodiments, a positive response is used to indicate that the third node has received the signal sent by the first node.
[0102] The information transmission method provided in this disclosure can be applied to... Figure 5 The second node 502 in the communication system shown. Figure 9 A flowchart illustrating another information transmission method is shown, such as... Figure 9 As shown, the information transmission method includes the following S901 to S903.
[0103] S901, Receive resource configuration request information from the first node.
[0104] Among them, the resource configuration request information is used to request the first time-frequency resource used by the first node to communicate with the third node.
[0105] S902, Send third information to the third node.
[0106] The third information is used to instruct the third node to listen on the second time-frequency resource used for communication between the first node and the third node. The second time-frequency resource is determined based on a pre-configured time-frequency resource pool.
[0107] In some embodiments provided by this disclosure Figure 9The information transmission method shown does not restrict the timing of S902. For example, after the second node receives the resource configuration request information (i.e., S901 above), it can send the third information to the third node, so that the node can immediately start listening to the second time-frequency resource. In this way, even if the second node cannot allocate the first time-frequency resource, the third node can still communicate with the first node through the second time-frequency resource. For another example, after the second node sends the resource configuration response information (i.e., S903 below), it can send the third information to the third node.
[0108] Furthermore, in some embodiments, the second node can identify the third node in the third information and add the identifier of the first node to the third information. In this way, if the third node receives a signal or data on the second time-frequency resource that is not the identifier of the third node, the third node can discard the signal or data.
[0109] S903, send resource configuration response information to the first node and the third node respectively.
[0110] Among them, the resource configuration response information is used to indicate whether to configure the first time-frequency resource.
[0111] It should be noted that the descriptions of resource configuration response information, resource configuration request information, third information, first time-frequency resources, second time-frequency resources, and related effects can be referred to the description on the first node side, and will not be repeated here in the embodiments of this disclosure.
[0112] The information transmission method provided in this disclosure can be applied to... Figure 5 The third node 503 in the communication system shown. Figure 10 A flowchart illustrating another information transmission method is shown, such as... Figure 10 As shown, the information transmission method includes the following steps S1001 to S1003.
[0113] S1001, Receive third information from the second node.
[0114] The third message instructs the third node to listen on the second time-frequency resource used for communication between the first and third nodes. The second time-frequency resource is determined based on a pre-configured time-frequency resource pool. The third message is triggered by the second node receiving a resource configuration request message, which requests the first time-frequency resource used for communication between the first and third nodes.
[0115] S1002. When the resource configuration response information sent by the second node is received to indicate the configuration of the first time-frequency resource, communication is performed with the first node on the first time-frequency resource.
[0116] S1003. If the resource configuration response information received from the second node indicates that the first time-frequency resource has not been configured, or if the resource configuration response information received from the second node has not been received, then communicate with the first node on the second time-frequency resource.
[0117] It should be noted that the descriptions of resource configuration response information, resource configuration request information, third information, first time-frequency resources, second time-frequency resources, and related effects can be referred to the description on the first node side, and will not be repeated here in the embodiments of this disclosure.
[0118] The information transmission method provided in this disclosure can be applied to... Figure 5 The communication system shown includes a first node 501, a second node 502, and a third node 503. Figure 11 A flowchart illustrating another information transmission method is shown, such as... Figure 11 As shown, the information transmission method includes the following steps S1101 to S1107.
[0119] S1101, The first node sends a resource configuration request to the second node.
[0120] S1102, The first node determines the second time-frequency resource for communication between the first node and the third node based on the pre-configured time-frequency resource pool.
[0121] S1103, The second node sends the third information to the third node.
[0122] S1104. The second node determines whether to send resource configuration response information to the first node based on the resource configuration request information.
[0123] S1105. If the resource configuration response information received from the second node indicates that the first time-frequency resource has not been configured, or if the resource configuration response information received from the second node has not been received, the first node shall communicate with the third node on the second time-frequency resource.
[0124] S1106, The third node sends feedback information to the first node on the second time-frequency resource.
[0125] S1107. When the first node receives a positive response from the third node on the second time-frequency resource, the first node stops listening to the second time-frequency resource.
[0126] The information transmission method provided in this disclosure can be applied to... Figure 5 The communication system shown includes a first node 501, a second node 502, and a third node 503. Figure 12 A flowchart illustrating another information transmission method is shown, such as... Figure 12 As shown, the information transmission method includes the following steps S1201 to S1208.
[0127] S1201, The first node sends a resource configuration request to the second node.
[0128] S1202, The first node determines the second time-frequency resource for communication between the first node and the third node based on the pre-configured time-frequency resource pool.
[0129] S1203, Send the third message to the third node.
[0130] S1204. The second node determines whether to send resource configuration response information to the first node based on the resource configuration request information.
[0131] S1205. When the resource configuration response information received from the second node is used to indicate the configuration of the first time-frequency resource, the first node communicates with the third node on the first time-frequency resource.
[0132] S1206, The third node sends feedback information to the first node on the first time-frequency resource.
[0133] S1207, The third node stops listening to the second time-frequency resource.
[0134] S1208. When the first node receives a positive response from the third node on the first time-frequency resource, the first node stops listening to the second time-frequency resource.
[0135] This disclosure discloses that a first node can send resource configuration request information to a second node, that is, use mode 1 to request the first time-frequency resource used for communication between the first node and the third node, and determine the second time-frequency resource used for communication between the first node and the third node based on the pre-configured time-frequency resource pool, that is, use mode 2 to determine the second time-domain resource.
[0136] If the received resource configuration response information from the second node indicates that the first time-frequency resource is configured, communication with the third node occurs on the first time-frequency resource, i.e., using mode 1. Alternatively, if the received resource configuration response information from the second node indicates that the first time-frequency resource is not configured, or if no resource configuration response information is received from the second node, communication with the third node occurs on the second time-frequency resource, i.e., using mode 2. As can be seen from the above, the first node can adaptively use either the first or second time-frequency resource to communicate with the third node under different circumstances. That is, it can combine modes 1 and 2 to communicate with the third node, thus ensuring normal communication between nodes as much as possible and improving the reliability of communication between nodes.
