However, how the terminal device obtains the resources required to send downlink commands and radio waves requires further discussion and research.

[0043] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0044] 1. Introduction to A-IOT

[0045] The Ambient Internet of Things (AIoT) refers to a new type of wireless communication system that is largely self-sufficient by using energy from the environment. It is an ecosystem for connecting and automating a large number of objects and devices, each of which is connected using low-cost, self-powered sensor nodes to form wireless sensor network devices.

[0046] As one of the key mechanisms for powering the Ambient IoT, energy harvesting is relied upon, eliminating the need for cables to power or recharge batteries in mobile devices and smart objects. Vibrations from equipment, machinery, and buildings, as well as propagation of radio signals in the surrounding environment, can be used to generate electricity.

[0047] Here are two possible standardized A-IOT topologies for 5G network devices:

[0048] In Topology 1, the Ambient IoT device directly and bidirectionally communicates with a base station. The communication between the base station and the ambient IoT device includes Ambient IoT data and / or signaling. This topology includes the possibility that the BS transmitting to the Ambient IoT device is a different from the BS receiving from the Ambient IoT device.

[0049] As shown in Figure 2, in Topology 1, Ambient IoT devices 210 communicate directly and bidirectionally with network devices 220. Communications between the network devices and the Ambient IoT devices include Ambient IoT data and / or signaling. This topology allows for the possibility that the base station (BS) used to send data to the Ambient IoT devices may be different from the base station (BS) used to receive data from the Ambient IoT devices.

[0050] In Topology 2, the Ambient IoT device communicates bidirectionally with an intermediate node between the device and basestation. In this topology, the intermediate node can be a relay, IAB node, UE, repeater, etc. which is capable of Ambient IoT.

[0051] As shown in Figure 3, in Topology 2, Ambient IoT devices 310 communicate bidirectionally with intermediate nodes 330 between devices and network devices 320. In this topology, intermediate nodes can be relays, Integrated Access Backhaul (IAB) nodes, UEs, repeaters, and more, enabling the Ambient IoT. Intermediate nodes transmit Ambient IoT data and / or signaling between base stations (BSs) and Ambient IoT devices.

[0052] In Topology 3, the Ambient IoT device transmits data / signalling to a basestation, and receives data / signalling from the assisting node; or the Ambient IoT device receives data / signalling from a basestation and transmits data / signalling to the assisting node.

[0053] As shown in Figure 4, in Topology 3, A-IoT device 410 sends data / signaling to network device 420 and receives data / signaling from assisting node 430; alternatively, A-IoT device 410 receives data / signaling from network device 420 and transmits the data / signaling to assisting node 430. In this topology, assisting nodes can be relays, IABs, UEs, repeaters, etc., which enable the A-IoT. This type of topology is primarily designed to address the problem of insufficient uplink transmission coverage for A-IoT devices, utilizing assisting nodes to send uplink signals to network devices.

[0054] The following two scenarios are identified in the related technology:

[0055] Deployment scenario 1 with Topology 1 (Indoor)

[0056] ○Basestation and coexistence characteristics: Micro-cell, co-site (network equipment and coexistence characteristics: micro-cell, co-site)

[0057] Deployment scenario 2 with Topology 2 and UE as intermediate node, under network control (network equipment is outdoors, tags are indoors, and their communications are relayed through intermediate nodes)

[0058] ○ Basestation and coexistence characteristics: Macro-cell, co-site (network equipment and coexistence characteristics: macro cell, co-site)

[0059] ○ The location of the intermediate node is indoor

[0060] 2. A-IOT device types

[0061] i.~1μW peak power consumption,has energy storage,initial sampling frequency offset(SFO)up to 10 X ppm, neither DL nor UL amplification in the device. The device's UL transmission is backscattered on a carrier wave provided externally. / / Worst capability (~1 μW peak power consumption with energy storage, initial sampling frequency offset (SFO) up to 10X ppm, neither DL nor UL amplification in the device. The device's UL transmission is backscattered on a carrier wave provided externally.)

[0062] ii.≤a few hundredμW peak power consumption 1 ,has energy storage,initial sampling frequency offset(SFO)up to 10 Xppm, both DL and / or UL amplification in the device. The device's UL transmission may be generated internally by the device, or be backscattered on a carrier wave provided externally. / / Best-in-class capabilities (≤ several hundred μW peak power consumption1, with energy storage, initial sampling frequency offset (SFO) up to 10X ppm, DL (DownLink) and / or UL (UpLink) amplification in the device. The device's UL transmission may be generated internally by the device, or be backscattered on a carrier wave provided externally.)

[0063] Traffic types: DO-DTT & DT with focus on rUC1 (indoor inventory) and rUC4 (indoor command).

[0064] DO-DTT: Data transmission generated by terminal devices triggered by downlink signaling of terminal devices

[0065] DT: Downlink signaling for terminal devices

[0066] 4. RFID Query Process

[0067] Exemplarily, the RFID Query process is shown in FIG5 .

[0068] 1. The interrogator selects a specific group through select signaling.

[0069] 2. The Interrogator sends a Query message after a certain period of time (indicating that a specific group or a specific UE is selected and contains a Q value).

[0070] 3. The tag randomly selects a value from the received (0, 2Q-1). The tag with a value of 0 sends RN16 to the network device after a certain period of time.

[0071] 4. If the network device receives RN16 correctly, it sends an ACK (Acknowledge Character) to the tag.

[0072] 5. The tag sends the tag ID (Identity Document) information to the network device.

[0073] 6. The network device sends a QueryRep (query repetition) message to the terminal device, with the random number held by all terminal devices minus 1. Then, returning to step 3, the network device resends the Query signaling.

[0074] 7. The terminal device may subsequently receive Query adjustment signaling: Upon receiving a QueryAdjust Tags first update Q, then pick a random value in the range (0,2Q–1), inclusive, and load this value into their slot counter. If a Tag, in response to the QueryAdjust, loads its slot counter with zero, then its reply to a QueryAdjust shall be shown in Table 6.35 using the immediate reply type specified in 6.3.1.6.1; otherwise, the Tag shall remain silent.A Tag shall respond to a QueryAdjust only if it received a prior Query. (Upon receipt of a QueryAdjust tag, it first updates Q and then selects a random value in the range (0, 2Q–1), inclusive, and loads that value into its slot counter. If a tag loads its slot counter to zero when responding to a QueryAdjust, its reply to the QueryAdjust shall be as shown in Table 6.35, using the immediate reply type specified in 6.3.1.6.1; otherwise, the tag shall remain silent. A tag shall respond to a QueryAdjust only if it received a previous Query.)

[0075] 8.A Tag in arbitrate shall decrement its slot counter every time it receives a QueryRep command (see 6.3.2.12.2.3) whose session parameter matches the session for the inventory round currently in progress, and it shall transition to the reply state and backscatter an RN16 when its slot counter reaches 0000h.

[0076] 5. In the case of SL relay (sideline relay), the terminal device requests air interface transmission resources from the network device

[0077] According to current standards, when a remote terminal sends data to a relay UE, it can only be configured to use air interface transmission resources in resource allocation mode 2 to transmit the data.

[0078] As shown in Figure 6, the echo characteristics of backscattering determine that after the intermediate terminal sends a command to the remote terminal, it needs to send a carrier wave without any information to the remote terminal after a certain time interval (such as interval T1). This helps the remote terminal perform OOK (On-Off Keying) modulation and send data back to the intermediate terminal.

[0079] 6. In resource allocation mode 1, the intermediate terminal requests transmission resources from the network device.

[0080] ■If the request is for a Configured grant transfer resource:

[0081] The UE shall set the contents of the UEAssistanceInformation message for configured grant assistance information for NR sidelink communication or NR sidelink positioning:

[0082] 1> if configured to provide configured grant assistance information for NR sidelink communication or NR sidelink positioning:

[0083] 2>include the sl-UE-AssistanceInformationNR; (including sl-UE-AssistanceInformationNR;)

[0084] The introduction of sl-UE-AssistanceInformationNR in related technologies is as follows:

[0085] Table 1: SL-TrafficPatternInfo field description

[0086] ■If the request is for a Dynamic grant transfer resource:

[0087] To ask for the Dynamic Grant resource, the intermediate UE will send the Sidelink Buffer Status Report MAC CE towards the network. (To request dynamic authorization resources, the intermediate UE will send the Sidelink Buffer Status Report MAC CE to the network equipment.) The structure of MAC CE is shown in Figure 7.

[0088] -Destination Index:The Destination Index field identifies the destination.The length of this field is 5bits.The value is set to one index corresponding to SL destination identity associated to same destination reported in sl-TxResourceReqList,sl-TxResourceReqListDisc and sl-TxResourceReqListCommRelay,if present.The value is indexed sequentially from 0in the same ascending order of SL destination identity in sl-TxResourceReqList, sl-TxResourceReqListDisc and sl-TxResourceReqListCommRelay as specified in TS 38.331[5].When multiple lists are reported, the value is indexed sequentially across all the lists in the same order as presented in SidelinkUEInformaitonNR message; (Target Index: The Target Index field identifies the target. This field is 5 bits long. The value is set to an index corresponding to the SL Target Identity associated with the same target reported in sl-TxResourceReqList, sl-TxResourceReqListDisc, and sl-TxResourceReqListCommRelay (if present). The values ​​are indexed sequentially starting from 0 in the same ascending order of the SL Target Identity in sl-TxResourceReqListDisc and sl-TxResourceReqListCommRelay as specified in TS 38.331 [5]. When multiple lists are reported, the values ​​are indexed sequentially in all lists in the same order as presented in the SidelinkUEInformaitonNR message;)

[0089] -LCG ID: The Logical Channel Group ID field identifies the group of logical channel(s) whose SL buffer status is being reported. The length of the field is 3 bits; (LCG ID: The Logical Channel Group ID field identifies the logical channel group whose SL buffer status is being reported. The length of the field is 3 bits;)

[0090] -Buffer Size: The Buffer Size field identifies the total amount of data available according to the data volume calculation procedure in TSs 38.322[3] and 38.323[4]across all logical channels of a logical channel group of a destination after the MAC PDU has been built (i.e., after the logical channel prioritization procedure, which may result the value of the Buffer Size field to zero). The amount of data is indicated in number of bytes. The size of the RLC headers and MAC subheaders are not considered in the buffer size computation. The length of this field is 8 bits. The values ​​for the Buffer Size field are shown in Table 6.1.3.1-2, respectively. For the Truncated SL-BSR format the number of Buffer Size fields included is maximised, while not exceeding the number of padding bits. The data size calculation process in 38.322[3] and 38.323[4] is based on the total amount of data available for all logical channels in the target logical channel group. The data size is expressed in bytes. The size of the RLC (Radio Link Control) header and MAC subheader are not considered in the buffer data size calculation. This field is 8 bits long.The values ​​of the Buffer Size field are shown in Table 6.1.3.1-2. For the truncated SL-BSR (Side Link Buffer Status Report) format, the number of buffer data size fields included is maximized while not exceeding the number of padding bits.

[0091] Using the above resource request method, the Intermediate terminal cannot inform the network device that the air interface transmission resources requested for the DL command (downlink command) and the carrier wave (carrier) are bundled. That is, if only a single air interface transmission resource is configured for the terminal, the terminal device can only be used to send downlink signaling and cannot receive data collected by the A-IOT device.

[0092] Please refer to FIG8 , which shows a flow chart of a resource request method provided by an embodiment of the present application. The method is performed by a terminal device 810 .

[0093] In step 810, the terminal device sends a first request, where the first request is used to obtain a first resource and / or a second resource. The first resource is used to send first information to the first device, and the second resource is used to send radio waves to the first device. The first resource and the second resource are associated with each other.

[0094] Accordingly, the network device receives the first request.

[0095] In some embodiments, the terminal device sends a first request to the network device.

[0096] In some embodiments, the terminal device sends a first request to the second device, and the second device forwards the first request to the network device.

[0097] In some embodiments, the first request includes at least one of the following information:

[0098] The purpose of the requested resource;

[0099] the type of the first device;

[0100] the role or type of the first information;

[0101] The number of resources requested;

[0102] The number of resource groups requested;

[0103] identification information of the first device;

[0104] Priority information of the requested resource;

[0105] Priority information of the requested resource group;

[0106] A time interval between a first resource and a second resource having an associated relationship;

[0107] The resource group includes a group of first resources and second resources having an associated relationship.

[0108] In some embodiments, the function of the requested resource refers to whether the requested resource is used to send first information to the first device or to send radio waves to the first device. It can also be understood as whether the requested resource is the first resource or the second resource, or the first resource and the second resource.

[0109] In some embodiments, the type of the first device may include at least one of the following: an A-IOT device, a relay terminal.

[0110] In some embodiments, the role or type of the first information includes at least one of the following: the first information is used to transmit a command to the first device, and the first information is used to transmit data to the first device.

[0111] In some embodiments, the first request is used to obtain N resource groups, where the resource group includes a group of first resources and second resources having an associated relationship, and N is a positive integer.

[0112] In some embodiments, a group of associated first resources and second resources may include at least one first resource and at least one second resource. Exemplarily, a resource group includes two resources, one first resource and one second resource. Exemplarily, a resource group includes M resources, one first resource and M-1 second resources, where M is an integer greater than or equal to 2. Exemplarily, a resource group includes M resources, P first resources and MP second resources, where M is an integer greater than or equal to 2 and P is a positive integer.

[0113] In some embodiments, the identification information of the first device is used to uniquely identify the first device, and the first device is the first device corresponding to the resource requested by the first request. In some embodiments, the identification information of the first device can be used to indicate an association relationship between the first resource and the second resource. In some embodiments, the transmission objects corresponding to the associated first resource and the associated second resource are the same first device.

[0114] In some embodiments, if the first request is for acquiring multiple resources, and the idle air interface resources may not be able to meet the needs of the multiple resources, the network device needs to determine which resource to allocate first based on the priority information of the multiple resources.

[0115] In some embodiments, if the first request is used to obtain N resource groups, and the idle air interface resources may not be able to meet the needs of the N resource groups, the network device needs to determine which resource group to allocate resources to first based on the priority information of the N resource groups.

[0116] In some embodiments, the first resource is used to send the first information to the first device, and after receiving the first information, the first device needs to perform operations such as parsing the first information, so there needs to be a certain time domain interval between the first resource and the second resource.

[0117] In some embodiments, the time domain interval between the above-mentioned associated first resource and second resource can be determined by the terminal device, or can be predefined or preconfigured, or can be reported by the first device to the terminal device. This application does not limit this.

[0118] In some embodiments, the first request is carried in RRC (Radio Resource Control) signaling, or the first request is carried in MAC CE signaling.

[0119] In some embodiments, the first device is an A-IOT device.

[0120] In some embodiments, the first device is configured to send feedback information for the first information in a backscattering manner after receiving the radio wave.

[0121] In some embodiments, the radio waves do not carry any information that is valid for the first device. In some embodiments, the radio waves do not carry any information. In some embodiments, the first device cannot properly parse and read the information carried in the radio waves.

[0122] In some embodiments, the radio waves may be a carrier wave that carries no information valid for the first device.

[0123] In some embodiments, after receiving the radio waves, the first device may perform spectrum shifting and then use backscattering to send feedback information for the first information, or it may directly use backscattering to send feedback information for the first information without performing spectrum shifting. This application does not limit this.

[0124] In some embodiments, the first information is sent by the terminal device to the first device. In some embodiments, the radio waves are sent by the terminal device to the first device, or the radio waves are sent by the second device to the first device.

[0125] In some embodiments, the method further includes the following step 820 .

[0126] Step 820: The terminal device receives response information for the first request, where the response information is used to indicate the allocated first resource and / or second resource, or the response information is used to indicate that the first resource and the second resource cannot be allocated.

[0127] Correspondingly, the network device sends response information for the first request.

[0128] In some embodiments, the network device allocates the first resource and the second resource to the terminal device based on the first request. In some embodiments, if the idle air interface resources cannot meet the requirements of the first resource and the second resource, the first resource and the second resource are not allocated, and thus the response information may be used to indicate that the first resource and the second resource cannot be allocated.

[0129] The technical solution provided in the embodiment of the present application is to enable the terminal device to request the first resource and the second resource with an associated relationship from the network device, so that the terminal device can obtain the resource pair for transmitting the first information and the radio wave on demand, avoiding the situation where the network device only allocates the first resource or the second resource, ensuring normal communication between the terminal device and the first device, and improving the stability of the communication system.

[0130] In some embodiments, the first request is used to obtain the first resource and / or the second resource. The first request can have multiple ways to implement the above functions. The following will exemplarily illustrate several possible implementations of the first request.

[0131] Mode 1: The first request includes a first sub-request and a second sub-request, the first sub-request is used to obtain the first resource, and the second sub-request is used to obtain the second resource.

[0132] In some embodiments, the first request includes a first sub-request and a second sub-request. In some embodiments, the first sub-request and the second sub-request may be sent simultaneously or at different times, which is not limited in this application. In some embodiments, the first sub-request and the second sub-request may be two independent request messages, or they may be combined into a single request message and sent simultaneously.

[0133] In some embodiments, the first sub-request includes index information of the second sub-request.

[0134] In some embodiments, the second sub-request includes index information of the first sub-request.

[0135] In some embodiments, the network device may determine a second resource associated with the first resource based on index information of the second sub-request carried in the first sub-request.

[0136] In some embodiments, the network device may determine the first resource associated with the second resource based on the index information of the first sub-request carried in the second sub-request.

[0137] In some embodiments, the first sub-request and the second sub-request may carry identification information of the first device. If the first sub-request and the second sub-request carry identification information of the same first device, the network device believes that the first resource requested by the first sub-request and the second resource requested by the second sub-request are associated with each other.

[0138] In some embodiments, the first sub-request may be used to obtain at least one first resource. If the first sub-request is used to obtain multiple first resources, the first sub-request includes at least one of the following: identification information of first devices corresponding to the multiple first resources, index information for second resources corresponding to the multiple first resources, and index information of a second sub-request for obtaining second resources associated with the multiple first resources.

[0139] In some embodiments, when a first sub-request is used to obtain multiple first resources, one first sub-request may be associated with multiple second sub-requests, for example, each second sub-request is used to obtain one second resource.

[0140] In some embodiments, when the first sub-request is used to obtain multiple first resources, the second sub-request is also used to obtain multiple second resources. In some embodiments, the first and second resources obtained by the associated first and second sub-requests are paired. In some embodiments, one first resource is associated with multiple second resources.

[0141] Exemplarily, a first sub-request is used to obtain three first resources. The first sub-request may be associated with a second sub-request, and the second sub-request is used to obtain second resources associated with the three first resources. Exemplarily, a first sub-request is used to obtain three first resources. The first sub-request may be associated with multiple second sub-requests. For example, if the first sub-request is associated with three second sub-requests, each second sub-request is used to obtain a second resource associated with one of the three first resources.

[0142] In some embodiments, the above step 820 can be implemented as the following step 821.

[0143] Step 821: The terminal device receives response information corresponding to the first request, where the response information is used to indicate the allocated first resource and / or second resource, or the response information is used to indicate that the first resource and the second resource cannot be allocated.

[0144] Correspondingly, the network device sends response information corresponding to the first request.

[0145] In some embodiments, the response information includes at least one of the following information:

[0146] Marking information for the first resource;

[0147] Marking information for the second resource;

[0148] Index information of a second resource associated with the first resource;

[0149] Index information of a first resource associated with a second resource.

[0150] In some embodiments, the response information includes first sub-information and second sub-information, the first sub-information is used to indicate the allocated first resource, and the second sub-information is used to indicate the allocated second resource.

[0151] In some embodiments, the first sub-information includes index information of the second sub-information, and / or the second sub-information includes index information of the first sub-information.

[0152] In some embodiments, the terminal device may determine a second resource associated with the first resource based on index information of the second sub-information carried in the first sub-information.

[0153] In some embodiments, the terminal device may determine the first resource associated with the second resource based on the index information of the first sub-information carried in the second sub-information.

[0154] In some embodiments, the first sub-information and the second sub-information may carry identification information of the first device. If the first sub-information and the second sub-information carry identification information of the same first device, the terminal device believes that the first resource indicated by the first sub-information and the second resource indicated by the second sub-information are associated with each other.

[0155] In some embodiments, the first sub-information may be used to indicate at least one allocated first resource. If the first sub-information is used to indicate multiple allocated first resources, the first sub-information includes at least one of the following: identification information of first devices corresponding to the multiple first resources, index information for second resources corresponding to the multiple first resources, and index information of second sub-information indicating allocated second resources associated with the multiple first resources.

[0156] In some embodiments, when the first sub-information is used to indicate multiple allocated first resources, one first sub-information may be associated with multiple second sub-information, for example, each second sub-information is used to indicate one allocated second resource.

[0157] In some embodiments, when the first sub-information indicates multiple allocated first resources, the second sub-information also indicates multiple allocated second resources. In some embodiments, the associated first sub-information and second sub-information indicate allocated first and second resources in pairs. In some embodiments, one first resource is associated with multiple second resources.

[0158] Exemplarily, one first sub-information is used to indicate three allocated first resources. The first sub-information may be associated with one second sub-information. The second sub-information is used to indicate second resources that are associated with the three allocated first resources. Exemplarily, one first sub-information is used to indicate three allocated first resources. The first sub-information may be associated with multiple second sub-information. For example, if the first sub-information is associated with three second sub-information, each second sub-information is used to indicate an allocated second resource that is associated with one of the three first resources.

[0159] Through the above method, the terminal device can obtain the first resource and the second resource with an associated relationship, avoiding the situation where the network device only allocates the first resource or the second resource, ensuring normal communication between the terminal device and the first device, and improving the stability of the communication system.

[0160] Method 2: The first request is used to obtain N resource groups, where the resource group includes a group of first resources and second resources having an associated relationship, and N is a positive integer.

[0161] In some embodiments, N is an integer greater than 1. For example, a terminal device may have communication connections with multiple first devices, or the terminal device may need to send multiple pieces of first information to the same first device. In this case, the terminal device may need to obtain multiple resource groups. To reduce power consumption when the terminal device sends the first request, multiple resource groups may be requested in one first request.

[0162] In some embodiments, N is equal to 1. Compared with method 1, this method only needs to send a first request to obtain the first resource and the second resource at the same time, thereby reducing the power consumption of the terminal device and improving the efficiency of resource requests.

[0163] In some embodiments, the first request is used to obtain N resource groups. The first resource and the second resource in the same resource group have the same index information. The network device can determine the first resource and the second resource with an associated relationship based on the index information.

[0164] Exemplarily, as shown in FIG9 , a first request is used to obtain N resource groups, each of which has different index information. The same index information corresponds to a group of associated first and second resources. For example, target index 1 corresponds to buffer data size 1 and buffer data size 2, where buffer data size 1 is used to obtain the first resource, and buffer data size 2 is used to obtain the second resource; target index N corresponds to buffer data size 2N-1 and buffer data size 2N, where buffer data size 2N-1 is used to obtain the first resource, and buffer data size 2N is used to obtain the second resource.

[0165] In some embodiments, the above step 820 can be implemented as the following step 822.

[0166] Step 822: The terminal device receives response information corresponding to the first request, where the response information is used to indicate the M allocated resource groups, or the response information is used to indicate that the resource groups cannot be allocated, where M is a positive integer less than or equal to N.

[0167] In some embodiments, the response information includes at least one of the following information:

[0168] Identification information of M resource groups;

[0169] Marking information for the first resource;

[0170] Marking information for the second resource;

[0171] Index information of a second resource associated with the first resource;

[0172] Index information of a first resource associated with a second resource;

[0173] Identification information of the first devices corresponding to the M resource groups respectively.

[0174] In some embodiments, if idle air interface resources cannot meet the needs of N resource groups, the network device may allocate the first resource and the second resource to some of the N resource groups based on priority information of the N resource groups. Exemplarily, the network device allocates the first resource and the second resource to the N resource groups in descending order based on the priority order of the N resource groups.

[0175] Through the above method, the terminal device can obtain the first resource and the second resource with an associated relationship, avoiding the situation where the network device only allocates the first resource or the second resource, ensuring normal communication between the terminal device and the first device, and improving the stability of the communication system.

[0176] Since the network device may not be able to allocate the first resource and the second resource to the terminal device, in this case, how should the terminal device obtain the first resource and the second resource? This application also provides an exemplary embodiment.

[0177] In some embodiments, the response information further includes first indication information, and the first indication information is used to determine a moment when the terminal device again requests the unsuccessfully allocated first resource and / or second resource.

[0178] In some embodiments, the first indication information is used to determine the first moment.

[0179] In some embodiments, the terminal device resends the first request before the first moment. In some embodiments, the terminal device resends the first request at any moment before the first moment.

[0180] In some embodiments, the terminal device resends the first request at the first moment.

[0181] In some embodiments, the terminal device sends the first request again after the first moment. In some embodiments, the terminal device sends the first request again at any moment after the first moment.

[0182] In some embodiments, the first indication information may also be used to determine the first duration.

[0183] In some embodiments, the terminal device resends the first request within the first duration. In some embodiments, the terminal device resends the first request after the first duration. In some embodiments, the start time of the first duration is the time when the terminal device receives the response information.

[0184] In some embodiments, the first moment and / or the first duration may be determined by the network device, or may be predefined or preconfigured, which is not limited in this application. For example, the first duration is preconfigured, and if the response information indicates that the first resource and the second resource cannot be allocated, the response information carries first indication information indicating the first duration, or the first moment is determined based on the first duration, and the response information carries first indication information indicating the first moment.

[0185] Through the above method, if the first resource and the second resource cannot be obtained, the terminal device can send the first request again after a period of time to obtain the first resource and / or the second resource, thereby ensuring the communication connection between the terminal device and the first device and improving the stability of the communication system.

[0186] In some embodiments, the radio waves may be sent by the terminal device to the first device, or by the second device to the first device, and this application does not limit this. In some embodiments, the second resource may be requested by the terminal device to the network device, or by the second device to the network device, and this application does not limit this.

[0187] The above two situations can be combined with each other. In this regard, several exemplary embodiments are given in the embodiments of the present application.

[0188] Solution 1: The terminal device obtains the second resource, and the second device sends radio waves

[0189] In some embodiments, the terminal device sends a request message for obtaining a second resource. The network device may indicate the second resource to the terminal device, which may be forwarded to the second device by the terminal device, or the network device may directly indicate the second resource to the second device. This application does not limit this.

[0190] 1. The network device indicates the second resource to the terminal device, which forwards it to the second device.

[0191] In some embodiments, after step 820 , the method further includes the following step 830 .

[0192] Step 830: The terminal device sends third information, where the third information is used to inform the second device of the second resource, and the second resource is used by the second device to send radio waves to the first device.

[0193] Accordingly, the second device receives the third information.

[0194] In some embodiments, the network device sends the second resource to the terminal device, which then forwards it to the second device.

[0195] In some embodiments, the third information includes at least one of the following information:

[0196] Index information of a first resource associated with a second resource;

[0197] identification information of the first device;

[0198] the role or type of the first information;

[0199] The type of the first device.

[0200] 2. The network device indicates the second resource to the second device

[0201] In some embodiments, the network device sends configuration information to the second device, where the configuration information is used to indicate allocated second resources, and the second resources are used by the second device to send radio waves to the first device.

[0202] Accordingly, the second device receives the configuration information.

[0203] In some embodiments, the method further includes at least one of the following steps 840 to 860 .

[0204] Step 840: The terminal device receives third indication information from the second device, where the third indication information is used to indicate that the second device has acquired the second resource.

[0205] Correspondingly, the second device sends third indication information.

[0206] Step 850: The terminal device receives fourth indication information from the network device, where the fourth indication information is used to indicate that the second resource has been allocated to the second device.

[0207] Correspondingly, the network device sends fourth indication information.

[0208] Step 860: After receiving the third indication information or the fourth indication information, the terminal device sends the first information to the first device.

[0209] In some embodiments, after the network device configures the second resource for the second device, it needs to inform the terminal device that the second resource has been configured for the second device, or the second device needs to inform the terminal device that the second resource has been acquired, to avoid the situation where the second device fails to acquire the second resource after the terminal device acquires the first resource, resulting in the terminal device being unable to acquire the data collected by the first device.

[0210] In some embodiments, if the terminal device does not receive the third indication information and does not receive the fourth indication information, the terminal device does not send the first information to the first device.

[0211] In some embodiments, if the above situation occurs, the terminal device may request the first resource and the second resource from the network device again.

[0212] Solution 2: The second device obtains the second resource and sends radio waves

[0213] In some embodiments, the method further includes the following step 870 .

[0214] In step 870, the terminal device sends a second indication message, where the second indication message is used to indicate relevant information of the first resource to the second device, or the second indication message is used to indicate relevant information of the second resource to the second device. After receiving the second indication message, the second device sends a second request for obtaining the second resource.

[0215] Correspondingly, the second device receives the second indication information.

[0216] In some embodiments, the second indication information is used to indicate relevant information of the first resource to the second device. The second device can determine relevant information of the second resource based on the relevant information of the first resource, and then the second device sends a second request, which is used to obtain the second resource.

[0217] In some embodiments, the terminal device determines the relevant information of the second resource based on the relevant information of the first resource, and then sends a second indication information to the second device. The second device sends a second request to the network device based on the relevant information of the second resource carried in the second indication information. The second request is used to obtain the second resource.

[0218] In some embodiments, the relevant information of the first resource includes at least one of the following:

[0219] Used to obtain index information of a first request for a first resource;

[0220] identification information of the first device;

[0221] the type of the first device;

[0222] the role or type of the first information;

[0223] priority information of the first resource;

[0224] The number of resources requested;

[0225] The time domain interval between the first resource and the second resource that have an associated relationship.

[0226] In some embodiments, the relevant information of the second resource includes at least one of the following:

[0227] Used to obtain index information of a first request for a first resource;

[0228] identification information of the first device;

[0229] the type of the first device;

[0230] the role or type of the first information;

[0231] priority information of the second resource;

[0232] The number of resources requested;

[0233] The time domain interval between the first resource and the second resource that have an associated relationship.

[0234] In some embodiments, the network device sends configuration information to the second device, where the configuration information is used to indicate allocated second resources, and the second resources are used by the second device to send radio waves to the first device.

[0235] Accordingly, the second device receives the configuration information.

[0236] In some embodiments, the method further includes at least one of the following steps 840 to 860 .

[0237] Step 840: The terminal device receives third indication information from the second device, where the third indication information is used to indicate that the second device has acquired the second resource.

[0238] Step 850: The terminal device receives fourth indication information from the network device, where the fourth indication information is used to indicate that the second resource has been allocated to the second device.

[0239] Step 860: After receiving the third indication information or the fourth indication information, the terminal device sends the first information to the first device.

[0240] For the introduction of steps 840 to 860 , please refer to the above-mentioned embodiment scheme 1, and this application will not repeat them here.

[0241] In some embodiments, there may also be a situation where the terminal device obtains the second resource and the terminal device sends radio waves. This situation can be referred to the introduction in the above embodiment. After receiving the response information sent by the network device, the terminal device sends the first information and radio waves to the first device. This embodiment of the present application will not be repeated.

[0242] In some embodiments, there may also be a situation where the second device acquires the second resource and the terminal device sends radio waves. Since this situation requires frequent information exchange between the terminal device and the second device, the power consumption required by the terminal device is relatively high.

[0243] In the above embodiments, the discussion is based on the terminal device acquiring the first resource. In some embodiments, the second device may also acquire the first resource and the second resource at the same time. Exemplarily, the terminal device sends a second indication message to the second device, and the second indication message is used to indicate to the second device the relevant information of the first resource and / or the relevant information of the second resource. The second device sends a second request to the network device based on the second indication message, and the second request is used to acquire the first resource and / or the second resource. For the introduction of the second request, please refer to the introduction of the first request in the above embodiments. After the second device receives the response information for the second request, it sends a fourth message to the terminal device, and the fourth message is used to indicate the first resource.

[0244] Regarding the resource request method described in the above embodiment, the present application also provides an exemplary embodiment in combination with actual practice.

[0245] Please refer to FIG. 10 , the terminal device 1010 sends a first request to the network device 1020 , and the network device 1020 sends response information for the first request to the terminal device 1010 .

[0246] In some embodiments, the terminal device 1010 sends multiple first requests to the network device 1020 , or may send one first request to the network device 1020 .

[0247] Correspondingly, the response information sent by the network device 1020 to the terminal device 1010 also has the above situation.

[0248] For example, the terminal device 1010 may send the first request to the network device 1020 in the following situations:

[0249] Case 1: The terminal device 1010 sends four first requests to the network device 1020, which are used to obtain the first resource required to send the first information to tag1, the second resource required to send radio waves to tag1, the first resource required to send the first information to tag2, and the second resource required to send radio waves to tag2.

[0250] Case 2: The terminal device 1010 sends two first requests to the network device 1020, and the two first requests are used to obtain the first resource and the second resource required for communication and transmission with tag1, and the first resource and the second resource required for communication and transmission with tag2.

[0251] Case 3: The terminal device 1010 sends a first request to the network device 1020, where the first request is used to obtain the first resource and the second resource required for communication and transmission with tag1, and the first resource and the second resource required for communication and transmission with tag2.

[0252] For example, the response information sent by the network device 1020 to the terminal device 1010 may fall into the following situations:

[0253] Case 1: The network device 1020 sends four response messages to the terminal device 1010, which are respectively used to indicate the first resources required to send the first information to tag1, the second resources required to send radio waves to tag1, the first resources required to send the first information to tag2, and the second resources required to send radio waves to tag2.

[0254] Case 2: The network device 1020 sends two pieces of response information to the terminal device 1010. The two pieces of response information are used to indicate the first resource and the second resource required for communication and transmission with tag1, and the first resource and the second resource required for communication and transmission with tag2.

[0255] Case 3: The network device 1020 sends a response message to the terminal device 1010, where the response message is used to indicate the first resource and the second resource required for communication and transmission with tag1, and the first resource and the second resource required for communication and transmission with tag2.

[0256] In some embodiments, the idle air interface resources may not be able to meet the resources required by tag1 and tag2, and the network device may determine the priority resources to be allocated based on the priority information of the first request sent by the terminal device. For example, if the terminal device indicates that the first resource and the second resource required for communication and transmission with tag1 have a higher priority, the network device will prioritize the allocation of the first resource and the second resource required for communication and transmission with tag1.

[0257] Through the above method, the terminal device can obtain the first resource and the second resource required for communication and transmission with the tag, avoiding the situation where the first resource is configured but the second resource is not configured, ensuring the communication and transmission between the terminal device and the tag, and improving the stability of the communication system.

[0258] In the above method embodiments, the technical solution of this application is described only from the perspective of the interaction between a terminal device and a network device. The above steps performed by the terminal device can be independently implemented as a resource request method on the terminal device side, and the above steps performed by the network device can be independently implemented as a resource request method on the network device side. In addition, the embodiments provided herein can be arbitrarily combined to form new embodiments, which are all within the scope of protection of this application.
