[0042] In a first aspect, an embodiment of the present disclosure provides a communication method, which is executed by an AIoT terminal. The method includes:

[0043] Determining, from a plurality of first frequency domain resources, a second frequency domain resource for uplink transmission;

[0044] The first information is sent to the network device on the second frequency domain resource.

[0045] In the above embodiment, the AIoT terminal selects the frequency domain resources for uplink transmission by itself, so that the AIoT terminal can determine the second frequency domain resources for uplink transmission from multiple first frequency domain resources, thereby improving channel utilization, and thus sending the first information to the network device on the second frequency domain resources, thereby improving communication efficiency.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, determining, from multiple first frequency domain resources, a second frequency domain resource for uplink transmission includes:

[0047] A first frequency domain resource including a first frequency value among multiple first frequency domain resources is determined as a second frequency domain resource; wherein the first frequency value is determined based on the frequency point of the continuous electromagnetic wave CW received by the AIoT terminal and / or the offset value of the backscattering of the AIOT terminal.

[0048] In the above embodiment, an optional implementation method is provided for an AIoT terminal to select frequency domain resources for uplink transmission, so that the AIoT terminal that receives the CW can realize autonomous selection of uplink transmission resources based on the frequency of the received CW and / or the offset value of the backscatter of the AIoT terminal, thereby improving channel utilization and communication efficiency.

[0049] In conjunction with some embodiments of the first aspect, in some embodiments, determining, from multiple first frequency domain resources, a second frequency domain resource for uplink transmission includes:

[0050] A first frequency domain resource is randomly selected from multiple first frequency domain resources as the second frequency domain resource.

[0209] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0210] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0211] In some embodiments, AIoT technology can be applied to sensor-related scenarios such as smart homes and environmental monitoring, so that AIoT terminals can report information to network devices when certain trigger conditions are met.

[0212] In some embodiments, AIoT technology can be applied to positioning scenarios. For example, AIoT technology can be used to find items, or AIoT technology can be used to locate items in a shopping mall.

[0213] In some embodiments, AIoT technology can be applied to command scenarios so that the AIoT terminal can respond to commands sent by network devices.

[0214] In some embodiments, AIoT terminals can be divided into two types: type A (also known as device type a, or device a) and type B (also known as device type b, or device b).

[0215] In some embodiments, device A does not store energy but instead operates based on backscatter. For an AIoT terminal that operates based on backscatter, a continuous wave (CW) energy source (also known as a CW node) is required to provide the electromagnetic wave for reflection.

[0216] Optionally, the CW node can be a separate node, or the CW node can be a network device that communicates with the AIoT terminal. The CW node can provide a CW with a constant amplitude to the AIoT terminal.

[0217] Optionally, the AIoT terminal can reflect the received CW to load the information to be transmitted onto the reflected wave and transmit it. The reflected wave and the CW can be of the same frequency, or there can be a certain frequency offset between the reflected wave and the CW.

[0218] Optionally, the CW can also serve to charge the AIoT terminal. Device A can receive the CW and activate the internal modules through the received CW, so that the activated modules can encode and / or modulate the information to be uploaded.

[0219] It should be noted that device a has lower complexity and consumes less power, but cannot amplify uplink or downlink signals.

[0220] In some embodiments, device B can store energy. That is, device B can operate using stored energy or battery energy rather than relying on CW power. Thus, device B can operate based on active transmission rather than backscatter. However, this is not limiting and device B can also operate based on backscatter.

[0221] It should be noted that compared with device a, device b is more complex and consumes more power. In addition, device b can amplify uplink or downlink signals.

[0222] Optionally, an AIoT terminal can support multiple deployment structures, that is, the AIoT terminal can access the network in multiple ways. Taking the network device as a base station as an example, the AIoT terminal can directly access the base station, or the AIoT terminal can communicate with the base station indirectly.

[0223] For example, referring to FIG2A , FIG2A is a schematic diagram of a deployment structure of an AIoT terminal according to an embodiment of the present disclosure. As shown in FIG2A , information can be directly transmitted between the AIoT terminal and the base station.

[0224] For another example, referring to FIG2B , FIG2B is a schematic diagram of a deployment structure of another AIoT terminal according to an embodiment of the present disclosure. As shown in FIG2B , information can be indirectly transmitted between the AIoT terminal and the base station through an intermediate node.

[0225] FIG3 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0226] In step S3101, the AIoT terminal determines a second frequency domain resource for uplink transmission from multiple first frequency domain resources.

[0227] The multiple first frequency domain resources may be multiple different frequency domain resources. For example, the multiple first frequency domain resources may be multiple frequency domain resources with different starting positions and / or ending positions.

[0228] Optionally, the multiple first frequency domain resources may be multiple channels, or the multiple first frequency domain resources may be multiple sub-channels, or the multiple first frequency domain resources may be multiple physical resource blocks (PRBs), or the multiple first frequency domain resources may be multiple resource elements (REs).

[0229] For example, the frequency band in which the AIoT terminal operates can be divided into multiple (such as N, where N is an arbitrary positive integer) channels or sub-channels, and the bandwidth of each channel or sub-channel can be X kilohertz (kHz), where X can be any positive value. Each channel and sub-channel can be further divided into multiple PRBs or multiple REs. The AIoT terminal can operate on one channel, or the AIoT terminal can operate on one sub-channel, or the AIoT terminal can operate on one PRB, or the AIoT terminal can operate on one RE.

[0230] Alternatively, a resource pool may be pre-configured for the AIoT terminal. The configured resource pool may include one or more channels, or the configured resource pool may include one or more sub-channels, or the configured resource pool may include one or more PRBs, or the configured resources may include one or more REs. Optionally, the network device may configure the resource pool for the AIoT terminal, but is not limited thereto.

[0231] By dividing the frequency domain resources into multiple channels, multiple sub-channels, multiple PRBs or multiple REs, and using multiple channels, multiple sub-channels, multiple PRBs or multiple REs as the first frequency domain resources for resource selection, the frequency domain resource selection granularity is refined to channels, sub-channels, PRBs or REs, thereby improving channel utilization.

[0232] Optionally, the AIoT terminal can implement the selection of the second frequency domain resources in a variety of ways. Several exemplary implementation methods are introduced below.

[0233] In some embodiments, a first frequency domain resource including a first frequency value among the plurality of first frequency domain resources may be determined as the second frequency domain resource.

[0234] The first frequency value may be determined based on the frequency of the CW received by the AIoT terminal and / or the offset value of the backscatter of the AIoT terminal. It should be noted that the frequency of the CW received by the AIoT terminal may be fixed.

[0235] For example, a network device can configure a CW for an AIoT terminal, and the configured CW frequency can be fixed at fc. The AIoT terminal can then select a first frequency domain resource containing a frequency of fc+offset or fc-offset as the second frequency domain resource. Here, fc is the frequency of the CW received by the AIoT terminal, and offset is the offset value of the backscatter of the AIoT terminal.

[0236] In some embodiments, a first frequency domain resource may be randomly selected from a plurality of first frequency domain resources as the second frequency domain resource.

[0237] For example, when CW is dynamically indicated by a network device or is any one or more downlink signals from a network device, the frequency of CW can be dynamically changed. In this case, a first frequency domain resource can be randomly selected from multiple first frequency domain resources as the second frequency domain resource.

[0238] Optionally, the randomly selected second frequency domain resource can be used for periodic transmission of the first information.

[0239] For example, for some services that require periodic information transmission, a second frequency domain resource for periodic transmission can be randomly selected from multiple first frequency domain resources. When the AIoT terminal performs periodic transmission, the selected second frequency domain resource can be used for each transmission.

[0240] In some embodiments, the AIoT terminal may not perform resource selection, but instead communicate based on any received CW.

[0241] Optionally, the first frequency domain resource reflected when backscattering is performed based on any CW received by the AIoT terminal can be determined as the second frequency domain resource.

[0242] In some embodiments, some first frequency domain resources can be randomly selected from multiple first frequency domain resources as multiple third frequency domain resources; the third frequency domain resources reflected when the third CW received by the AIoT terminal is backscattered are determined as second frequency domain resources.

[0243] For example, the AIoT terminal can randomly select multiple first frequency domain resources as multiple third frequency domain resources. These multiple third frequency domain resources can form a candidate resource set. The AIoT terminal can select the second frequency domain resource in the candidate resource set based on any received CW. Taking the frequency point f1 of the CW received by the AIoT terminal as an example, the AIoT terminal can make a judgment in the candidate resource set, thereby determining the third frequency domain resource containing the frequency point f1+offset or f1-offset in the candidate resource set as the second frequency domain resource. The third frequency domain resource containing the frequency point f1+offset or f1-offset is the third frequency domain resource reflected when the CW with the frequency point f1 is backscattered. Offset is the offset value of the backscattering of the AIoT terminal.

[0244] In some embodiments, the AIoT terminal can select a fourth frequency domain resource with less interference from multiple first frequency domain resources, thereby determining the second frequency domain resource in the fourth frequency domain resources.

[0245] Among them, the fourth frequency domain resource can be a frequency domain resource in which the reference signal receiving power (Reference Signal Receiving Power, RSRP) in the first frequency domain resource is less than or equal to the first threshold, or the fourth frequency domain resource is a frequency domain resource in which the received signal strength indication (Received Signal Strength Indication, RSSI) in the first frequency domain resource is less than or equal to the second threshold, or the fourth frequency domain resource is a frequency domain resource in which the reference signal receiving quality (Reference Signal Receiving Quality, RSRQ) in the first frequency domain resource is greater than or equal to the third threshold.

[0246] The first threshold value may be predefined. Alternatively, the first threshold value may be preconfigured; for example, the network device may send preconfiguration information to the AIoT terminal, and the preconfiguration information may be used to indicate the first threshold value corresponding to RSRP, so that the AIoT terminal can determine the first threshold value based on the received preconfiguration information. Alternatively, the first threshold value may be dynamically indicated by the network device through control information; for example, the network device may send control information to the AIoT terminal, and the control information may be used to indicate the first threshold value corresponding to RSRP, so that the AIoT terminal can determine the first threshold value based on the received control information.

[0247] In addition, the second threshold value may be predefined. Alternatively, the second threshold value may be preconfigured; for example, the network device may send preconfiguration information to the AIoT terminal, and the preconfiguration information may be used to indicate the second threshold value corresponding to the RSSI, so that the AIoT terminal can determine the second threshold value based on the received preconfiguration information. Alternatively, the second threshold value may be dynamically indicated by the network device through control information; for example, the network device may send control information to the AIoT terminal, and the control information may be used to indicate the second threshold value corresponding to the RSSI, so that the AIoT terminal can determine the second threshold value based on the received control information.

[0248] In addition, the third threshold value may be predefined. Alternatively, the third threshold value may be preconfigured; for example, the network device may send preconfiguration information to the AIoT terminal, and the preconfiguration information may be used to indicate the third threshold value corresponding to RSRQ, so that the AIoT terminal can determine the third threshold value based on the received preconfiguration information. Alternatively, the third threshold value may be dynamically indicated by the network device through control information; for example, the network device may send control information to the AIoT terminal, and the control information may be used to indicate the second threshold value corresponding to RSRQ, so that the AIoT terminal can determine the third threshold value based on the received control information.

[0249] Optionally, the RSRP corresponding to each of the multiple first frequency domain resources can be obtained within the first time window; or, the RSSI corresponding to each of the multiple first frequency domain resources can be obtained within the first time window; or, the RSRQ corresponding to each of the multiple first frequency domain resources can be obtained within the first time window.

[0250] The first time window can be determined based on the time when the AIoT terminal receives the first CW and the duration of the measurement reference signal. For example, the first time window can be [t1, t1 + tproc0], where t1 is the time when the AIoT terminal receives the first CW, and tproc0 is the duration required to measure the reference signal.

[0251] After obtaining the RSRP or RSSI or RSRQ corresponding to each first frequency domain resource, the fourth frequency domain resource can be determined.

[0252] For example, within the first time window, the AIoT terminal can exclude the first frequency domain resources whose RSRP values ​​exceed the first threshold based on the RSRP value of the reference signal of the measurement control signal or data among multiple first frequency domain resources, and use the remaining first frequency domain resources as the fourth frequency domain resources.

[0253] Alternatively, the AIoT terminal can exclude first frequency domain resources whose RSSI values ​​exceed a second threshold based on the RSSI value of the reference signal of the measurement control signal or data among multiple first frequency domain resources within the first time window, and use the remaining first frequency domain resources as fourth frequency domain resources.

[0254] Alternatively, the AIoT terminal can, within the first time window, exclude first frequency domain resources whose RSRQ values ​​do not exceed the third threshold among multiple first frequency domain resources based on the RSRQ value of the reference signal of the measurement control signal or data, and use the remaining first frequency domain resources as fourth frequency domain resources.

[0255] After the fourth frequency domain resources are determined, the second frequency domain resources for uplink transmission may be randomly selected from the fourth frequency domain resources.

[0256] Optionally, the second frequency domain resources selected from the fourth frequency domain resources may include the second frequency domain resources used to send the first information this time and the second frequency domain resources used to send the first information in the future.

[0257] Optionally, if the first information is sent periodically, when randomly selecting the second frequency domain resource used to send the first information this time and the second frequency domain resource used to send the first information in the future from multiple fourth frequency domain resources, one fourth frequency domain resource can be randomly selected from the multiple fourth frequency domain resources as the second frequency domain resource used to send the first information this time, thereby determining the second frequency domain resource used to send the first information in the future based on the second frequency domain resource used to send the first information this time and the signaling sending period.

[0258] For example, for first information that needs to be sent periodically, resource r1 can be randomly selected from the fourth frequency domain resources as the second frequency domain resource used to send the first information this time, thereby using resources r1+p, resources r1+2p, ..., and resources r1+np as the second frequency domain resources for sending the first information in the future. Where p can be the signaling transmission period of the AIoT terminal. Optionally, when determining r1+p, resources r1+2p, ..., and resources r1+np, p can be converted into a physical time slot to facilitate resource determination.

[0259] In some embodiments, the AIoT terminal may determine the second frequency domain resource from a plurality of first frequency domain resources according to a first rule.

[0260] Optionally, the first rule may be predefined, or the first rule may be preconfigured, or the first rule may be indicated by the network device to the terminal.

[0261] It should be noted that there may be multiple first rules, and the embodiments of the present disclosure do not limit the first rule.

[0262] For example, the first frequency domain resource with the smallest RSRP value among multiple first frequency domain resources can be determined as the second frequency domain resource.

[0263] Alternatively, the first frequency domain resource with the smallest RSSI value among the multiple first frequency domain resources may be determined as the second frequency domain resource;

[0264] Alternatively, the first frequency domain resource with the largest RSRQ value among the multiple first frequency domain resources may be determined as the second frequency domain resource.

[0265] Step S3102: The AIoT terminal sends first information to the network device on the second frequency domain resources.

[0266] It should be noted that after the AIoT terminal completes the determination of the second frequency domain resources, it can realize the transmission of the first information on the second frequency domain resources.

[0267] In some embodiments, the AIoT terminal determines a first frequency domain resource containing a first frequency value as a second frequency domain resource, and the first frequency value is determined based on the frequency point of the CW received by the AIoT terminal and / or the offset value of the backscattering of the AIoT terminal. The AIoT terminal can use the received CW to send the first information on the second frequency domain resource.

[0268] For example, if the frequency of the CW received by the AIoT terminal is fixed, the AIoT terminal can use the CW with the fixed frequency to send the first information on the second frequency domain resource. Alternatively, the frequency of the CW is not fixed, and the frequency of the CW is different for the AIOT device at different times.

[0269] In some embodiments, the second frequency domain resource is randomly selected from the first frequency domain resource, and the AIoT terminal can determine the first CW corresponding to the second frequency domain resource, thereby using the first CW to send the first information to the network device in the first time unit. The first CW is a CW that can be reflected on the second frequency domain resource through backscattering, and the first time unit is the time slot where counter 0 is located.

[0270] Optionally, the first CW corresponding to the second frequency domain resource can be determined before the second time unit. The second time unit can be determined based on the time slot where counter 0 is located and the backscattering processing duration, and the backscattering processing duration can be the processing time for the AIoT terminal to complete the modulation onto the reflected wave.

[0271] For example, the AIoT terminal can determine which CW to use for backscattering before slot n-tproc0, where slot n is the time slot where the counter is 0 and tproc0 is the backscattering processing duration.

[0272] Taking the frequency point of the first CW as f1 as an example, the second frequency domain resource reflected when the first CW is backscattered can be a frequency domain resource including the frequency point f1+offset or f1-offset, and offset is the offset value of the backscattering of the AIoT terminal.

[0273] Optionally, if it is determined that there is no first CW corresponding to the second frequency domain resource, the AIoT terminal may give up sending the first information to the network device.

[0274] For example, when the AIoT terminal determines before slot n-tproc0 that backscattering using any received CW cannot be reflected on the selected second frequency domain resource, the AIoT terminal can discard the current transmission.

[0275] Alternatively, if it is determined that the first CW corresponding to the second frequency domain resource does not exist, the terminal may determine the second CW corresponding to the second frequency domain resource, and thus start using the second CW at the third time to send the first information to the network device.

[0276] The second CW is a CW that can be reflected onto the second frequency domain resource through backscattering, and the second CW has a different frequency than the first CW. Furthermore, the third time is the time slot corresponding to the first duration after the first time unit, or the third time is the time slot where counter 0 in the regenerated counter is located.

[0277] For example, when the AIoT terminal determines before slotn-tproc0 that backscattering using any received CW cannot be reflected on the selected second frequency domain resource, the AIoT terminal can determine after slot n and before slot n+Tmax whether there are other CWs (denoted as CWn) that meet the conditions. The frequency of CWn is fn. When backscattering using CWn can be reflected on the selected second frequency domain resource (that is, the second frequency domain resource includes the frequency fn+offset or the second frequency domain resource includes the frequency fn-offset), CWn is used to send the first information.

[0278] Tmax is the first duration, and the first duration may be a packet delay budget (PDB), or the first duration may be a maximum signaling delay value, but is not limited thereto.

[0279] Alternatively, when the AIoT terminal determines before slotn-tproc0 that backscattering using any received CW cannot be reflected on the selected second frequency domain resource, the AIoT terminal can regenerate the first counter and before the counter reaches 0, determine whether there are other CWs (denoted as CWn) that meet the conditions. The frequency of CWn is fn. When backscattering using CWn can be reflected on the selected second frequency domain resource (that is, the second frequency domain resource includes the frequency fn+offset or the second frequency domain resource includes the frequency fn-offset), CWn is used to send the first information.

[0280] In some embodiments, the AIoT terminal does not select resources, but uses the first frequency domain resource reflected when backscattering is performed based on any CW it receives as the second frequency domain resource. The AIoT terminal can use the CW it receives on the second frequency domain resource to continuously send the first information to the network device starting from the first time unit.

[0281] For example, if the AIoT terminal does not select resources, the AIoT terminal can use any received CW for backscattering before the first time unit (that is, slot n (the time slot where the counter is 0)) to realize information transmission. However, it is necessary to send M time slots (slots) or M time units continuously starting from slot n, where M can be any positive integer value.

[0282] It should be noted that by sending continuously in time, the sending success rate can be improved, because the AIoT terminal may conflict with other AIoT terminals in slot n, but by sending continuously in time, there may be no conflict in subsequent slots, thereby improving the sending success rate.

[0283] In some embodiments, the AIoT terminal first randomly selects part of the first frequency domain resources as multiple third frequency domain resources, and then implements resource selection in the third frequency domain resources. The selected second frequency domain resources can be the frequency domain resources reflected when the third CW received by the AIoT terminal is backscattered. The AIoT terminal can use the third CW to send the first information on the second frequency domain resources.

[0284] For example, when the AIoT terminal receives a downlink signal with a frequency of f1, the downlink signal with a frequency of f1 can be used as the third CW. The AIoT terminal can determine the second frequency domain resources based on the frequency domain resources emitted when the third CW is backscattered, thereby using the third CW with a frequency of f1 on the second frequency domain resources to send the first information.

[0285] Optionally, if it is determined that the third frequency domain resource reflected when backscattering is performed based on the third CW does not exist in the multiple third frequency domain resources, the terminal may give up sending the first information to the network device.

[0286] In some embodiments, the AIoT terminal selects the second frequency domain resource in the first frequency domain resource with less interference (that is, the fourth frequency domain resource), and the AIoT terminal can use its own stored electrical energy to actively send the first information on the second frequency domain resource.

[0287] In some embodiments, the AIoT terminal selects the second frequency domain resource according to the first rule, and the AIoT terminal can use its own stored electrical energy to actively send the first information on the second frequency domain resource.

[0288] Optionally, the first information may include at least one of control information, data information, and high-layer signaling. Taking the case where the first information includes control information and data information as an example, the AIoT terminal may send the first information including the control information and the data information, and the control information may indicate a second frequency domain resource for sending the data information.

[0289] In some embodiments, the network device can receive the first information sent by the AIoT terminal on the second frequency domain resource.

[0350] FIG4B is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG4B , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0351] Step S4201: Acquire first information on a second frequency domain resource.

[0352] The optional implementation of step S4201 can be found in step S3101 and step S3102 of FIG. 3 , the optional implementation of step S4101 and step S4102 of FIG. 4A , and other related parts in the embodiments involved in FIG. 3 and FIG. 4A , which will not be repeated here.

[0353] In some embodiments, the network device can receive the first information sent by the AIoT terminal on the second frequency domain resource, but is not limited to this, and can also receive the first information sent by other entities.

[0354] Optionally, the first information includes at least one of control information, data information, and high-layer signaling.

[0355] Among them, the second frequency domain resources can be determined by the AIoT terminal from multiple first frequency domain resources, and the multiple first frequency domain resources can include any one of multiple channels, multiple sub-channels, multiple PRBs, and multiple REs.

[0356] Optionally, the specific implementation method of the AIoT terminal determining the second frequency domain resource from multiple first frequency domain resources can be found in the embodiment corresponding to Figure 4A, which will not be repeated here.

[0357] In some embodiments, the network device sends pre-configuration information to the AIoT terminal, where the pre-configuration information is used to indicate at least one of a first threshold corresponding to RSRP, a second threshold corresponding to RSSI, and a third threshold corresponding to RSRQ.

[0358] In some embodiments, the network device sends control information to the AIoT terminal, where the control information is used to indicate at least one of a first threshold corresponding to RSRP, a second threshold corresponding to RSSI, and a third threshold corresponding to RSRQ.

[0359] The communication method involved in the embodiment of the present disclosure may at least include step S4201, but is not limited thereto.

[0360] In an embodiment of the present disclosure, step S4201 may be combined with step S4102 of FIG. 4A .

[0361] In the embodiment of the present disclosure, the operating frequency band of the AIoT device (that is, the AIoT terminal) can be divided into multiple (such as N) channels or sub-channels, the bandwidth of each channel or sub-channel can be X khz, each channel or sub-channel can include one or more PRBs, or each channel or sub-channel can include one or more REs, each AIoT device can work on one or more channels, or each AIoT device can work on one or more sub-channels, or each AIoT device can work on one or more PRBs, or each AIoT device can work on one or more REs.

[0362] Optionally, a network device (such as a base station / UE / intermediate node) can also pre-configure a resource pool for the AIoT device. The resource pool may include one or more channels, or the resource pool may include one or more sub-channels, or the resource pool may include one or more PRBs, or the resource pool may include one or more REs.

[0363] Based on the above settings of the embodiments of the present disclosure, the granularity of frequency domain resource allocation can be any one of channel, subchannel, PRB, and RE. The frequency domain resources selected for one information transmission may include one or more subchannels, or the frequency domain resources selected for one information transmission may include one or more PRBs, or the frequency domain resources selected for one information transmission may include one or more REs, thereby improving channel utilization.

[0364] In some embodiments, device a and device b need to collect energy from surrounding devices and use the signals of the surrounding devices as CW to achieve information transmission based on backscattering. Therefore, the method for device a and device b to select resources can be as follows.

[0365] Optionally, when CW is pre-configured by the network device, CW can be continuously sent for a period of time, with a fixed frequency of fc and a bandwidth of B. The AIoT device can select a frequency domain resource containing a frequency of fc+offset or fc-offset, and the offset value can be 0.

[0366] Optionally, when CW is pre-configured by the network device, CW can be continuously sent for a period of time, its frequency is fixed at fc, and the bandwidth is B. Then the AIoT device can not perform resource selection, but use any 1 CW received before sending time slot slot n (the time slot where the counter is 0) to transmit information based on backscattering, but it is necessary to send M slots continuously or M time units continuously starting from slot n.

[0367] By sending data continuously over time, the success rate of sending data can be increased. This is because there may be a conflict with other AIoT devices in slot n, but by sending data continuously over time, there is a possibility that there will be no conflict in the next slot and the data will be sent successfully, thus improving the success rate of sending data.

[0368] Optionally, when CW is pre-configured by the network device, CW can be continuously sent for a period of time, its frequency is fixed at fc, and its bandwidth is B, then the AIoT device can randomly select multiple resources to form a candidate resource set, and the candidate resource set can include multiple frequency domain resources (such as r1, r2, r3, r4, ..., ri, ..., rn). The AIoT device can judge in the candidate resource set based on the received 1 CW (frequency is f1). If it is determined that the candidate resource set contains frequency domain resources with a frequency of f1+offset or f1-offset, then the CW with a frequency of f1 is used for backscattering to send the first information to the network device on the frequency domain resources containing the frequency of f1+offset or f1-offset. Otherwise, if the candidate resource set does not contain a frequency domain resource with a frequency of f1+offset, and the candidate resource set does not contain a frequency domain resource with a frequency of f1-offset, then drop this transmission.

[0369] For example, when an AIoT device receives a downlink signal with a frequency point f1, it can use the signal as a CW. The AIoT device can use the CW to reflect to the frequency point where the frequency domain resource r3 in the candidate resource set is located (the frequency where the frequency domain resource r3 is located includes the frequency point f1+offset, or the frequency where the frequency domain resource r3 is located includes the frequency point f1-offset). Then, the CW can be used for backscattering to send the first information to the network device on the frequency domain resource r3.

[0370] Optionally, when CW is dynamically indicated by a network device, or when CW is any one or more downlink signals from a network device whose frequency points are dynamically changing, the AIoT device can randomly select frequency domain resources for one transmission in the resource pool.

[0371] Optionally, the AIoT device can randomly select frequency domain resources from the resource pool for periodic transmission. For example, for services that require periodic information transmission, with a transmission period of p1, each transmission can use the frequency domain resources randomly selected by the AIoT device from the resource pool.

[0372] In this case, taking the frequency domain resource selected by the AIoT device as frequency domain resource 1, and the AIoT device being charged by CW with frequency f1 and entering the working state as an example, the AIoT device can have the following behaviors:

[0373] Behavior 1: When the AIoT device determines which CW to use for backscattering before slot n-tproc0 (slotn is the time slot where the counter is 0, tproc0 is the backscattering processing time, such as the processing time for the AIoT device to complete the encoding and modulation onto the reflected wave), and it can be reflected on the selected frequency domain resource r1 (that is, the frequency domain resource r1 contains the frequency point f1+offset, or the frequency domain resource r1 contains the frequency point f1-offset), then the CW is used for backscattering and the first information is sent to the network device starting at slot n.

[0374] Behavior 2: When the AIoT device determines that any received CW for backscattering before slot n-tproc0 cannot be reflected on the frequency of the selected frequency domain resource r1 (that is, the frequency domain resource r1 does not contain the frequency point f1+offset, and the frequency domain resource r1 does not contain the frequency point f1-offset), then,

[0375] Method 1: Directly drop this sending.

[0376] Method 2: After slot n and before slot n+Tmax, when there is another CW (CWn, frequency fn of the CWn) that meets the conditions, that is, when the AIoT device uses the CWn for backscattering and can be reflected on the selected frequency domain resource r1 (that is, the frequency domain resource r1 includes the frequency point fn+offset, or the frequency domain resource r1 includes the frequency point fn-offset), then the AIoT device can use the CWn for backscattering to start sending the first information to the network device. Otherwise, the current transmission is dropped.

[0377] Alternatively, before another counter is generated and the counter reaches 0, when there is another CW (CWn, the frequency point fn of the CWn) that meets the conditions, that is, when the AIoT device uses the CWn for backscattering and can be reflected on the selected frequency domain resource r1 (that is, the frequency domain resource r1 includes the frequency point fn+offset, or the frequency domain resource r1 includes the frequency point fn-offset), the AIoT device can use the CWn for backscattering to start sending the first information to the network device. Otherwise, drop this transmission.

[0378] Tmax is the packet delay budget PDB or the maximum signaling delay value.

[0379] Optionally, when CW is dynamically indicated by a network device, or when CW is any one or more downlink signals from a network device whose frequency point changes dynamically, the AIoT device may not perform resource selection, but may use any 1 CW received before sending time slot n (the time slot where the counter is 0) to transmit information based on backscattering, but it is necessary to send M slots continuously or M time units continuously starting from slot n.

[0380] By sending data continuously over time, the success rate of sending data can be increased. This is because there may be a conflict with other AIoT devices in slot n, but by sending data continuously over time, there is a possibility that there will be no conflict in the next slot and the data will be sent successfully, thus improving the success rate of sending data.

[0381] Optionally, when CW is dynamically indicated by a network device, or when CW is any one or more downlink signals from a network device, and its frequency point is dynamically changing, the AIoT device can randomly select multiple resources to form a candidate resource set. The candidate resource set can include multiple frequency domain resources (such as r1, r2, r3, r4, ..., ri, ..., rn). The AIoT device can judge in the candidate resource set based on the received 1 CW (frequency point f1). If it is determined that the candidate resource set contains frequency domain resources with a frequency point of f1+offset or f1-offset, the CW with a frequency point of f1 is used for backscattering to send the first information to the network device on the frequency domain resources containing the frequency point f1+offset or f1-offset. Otherwise, if the candidate resource set does not contain a frequency domain resource with a frequency point of f1+offset, and the candidate resource set does not contain a frequency domain resource with a frequency point of f1-offset, then drop this transmission.

[0382] For example, when an AIoT device receives a downlink signal with a frequency point f1, it can use the signal as a CW. The AIoT device can use the CW to reflect to the frequency point where the frequency domain resource r3 in the candidate resource set is located (the frequency where the frequency domain resource r3 is located includes the frequency point f1+offset, or the frequency where the frequency domain resource r3 is located includes the frequency point f1-offset). Then, the CW can be used for backscattering to send the first information to the network device on the frequency domain resource r3.

[0383] In some embodiments, device B may be equipped with a battery and thus store electrical energy, so that device B can actively send information without relying on backscatter. Therefore, device B may also select resources in the following manner.

[0384] Optionally, the AIoT device can exclude frequency domain resources in the resource pool whose RSRP measurement values ​​exceed a first threshold (that is, the RSRP corresponding threshold) based on the RSRP value of the reference signal for measuring the control signal or data in the time window [t1, t1+tproc0], and determine the remaining frequency domain resources as one candidate resource set, thereby randomly selecting one frequency domain resource for this transmission and multiple frequency domain resources for future transmission from the candidate resource set.

[0385] The first threshold is predefined, or the first threshold is preconfigured, or the first threshold is dynamically indicated through control information.

[0386] It should be noted that the RSRP measurement value may be an RSRP value obtained by measuring a reference signal based on control information, or the RSRP measurement value may be an RSRP value obtained by measuring a reference signal based on data information.

[0387] Among them, for the time window [t1, t1+tproc0], time t1 is the time when the AIoT device receives the first CW, and tproc0 is the processing time required for RSRP measurement and comparison with the threshold.

[0389] The second threshold is predefined, or the second threshold is preconfigured, or the second threshold is dynamically indicated through control information.

[0390] Among them, for the time window [t1, t1+tproc0], time t1 is the time when the AIoT device receives the first CW, and tproc0 is the processing time required for RSSI measurement and comparison with the threshold.

[0391] Optionally, the AIoT device can exclude frequency domain resources in the resource pool whose RSRQ measurement values ​​do not exceed a third threshold (that is, the RSSI corresponding threshold) based on the RSRQ value of the reference signal for measuring the control signal or data in the time window [t1, t1+tproc0], and determine the remaining frequency domain resources as one candidate resource set, thereby randomly selecting one frequency domain resource for this transmission and multiple frequency domain resources for future transmission from the candidate resource set.

[0394] Particularly, for periodic transmission, the multiple resources selected for periodic transmission in the candidate resource set may be r1, r1+p, r1+2p, . . . , r1+np.

[0395] In some embodiments, when CW is dynamically indicated by a network device, or when CW is any one or more downlink signals from a network device whose frequency points are dynamically changing, the AIoT device can select frequency domain resources in the resource pool according to certain rules.

[0396] For example, in the time window [t1, t1+tproc0], the AIoT device can sort the frequency domain resources in ascending order based on the RSRP value of the reference signal for measuring the control signal or data, and when selecting the frequency domain resources, give priority to the frequency domain resources with the smallest corresponding RSRP value.

[0397] Alternatively, the AIoT device can sort the frequency domain resources in ascending order based on the RSSI value of the reference signal for measuring the control signal or data in the time window [t1, t1+tproc0], and when selecting frequency domain resources, give priority to the frequency domain resources with the smallest corresponding RSSI value.

[0398] Alternatively, the AIoT device can sort the frequency domain resources in descending order based on the RSRQ value of the reference signal for measuring the control signal or data in the time window [t1, t1+tproc0], and when selecting frequency domain resources, give priority to the frequency domain resources with the largest corresponding RSRQ value.

[0399] Optionally, regardless of the method used to select the frequency domain resources, the AIoT device can be supported to send control information and data information at the same time, and the control information can be used to indicate the frequency domain resources used by the data information.
