[0128] In some embodiments, the access network device, the core network device, or the network device can be replaced by a terminal. For example, the various embodiments of the present disclosure can also be applied to a structure in which the communication between the access network device, the core network device, or the network device and the terminal is replaced by communication between multiple terminals (for example, device-to-device (D2D), vehicle-to-everything (V2X), etc.).

[0133] A-IOT devices can be divided into three categories. Type A devices do not support energy storage or only support a small amount of energy storage, and work based on backscatter. They have the lowest complexity and very low power consumption. For example, Type A devices need to receive wireless signals to obtain energy to activate the internal receiving and processing module. Type B devices support energy storage and work based on backscatter. Their complexity and power consumption are higher than Type A devices, but still maintain a relatively low level. The energy that Type B devices can store is still relatively limited. Type C devices support energy storage and work based on active transmission, that is, Type C devices amplify and transmit information through power amplifiers. Type C devices generally need to store more energy to support active transmission of information.

[0134] In related technologies, A-IoT devices need to harvest energy from surrounding devices and implement backscatter transmission based on their signals. A-IoT devices can also operate based on active transmission. A-IoT devices can multiplex uplink and downlink transmissions with other cellular communications on the same carrier. Therefore, coordinating the uplink and downlink transmissions of A-IoT devices with other cellular communications is a challenge that needs to be addressed.

[0135] Therefore, the present disclosure proposes a communication method and device, a communication system, a communication device, and a storage medium, which define the uplink and downlink OFDM symbols occupied by the uplink and downlink transmissions of the A-IOT device, thereby coordinating the resource allocation of the uplink and downlink transmissions with other cellular communications, thereby supporting efficient data transmission of the A-IOT device.

[0159] Figure 2 is an interactive diagram of a communication method provided by an embodiment of the present disclosure. As shown in Figure 2, an embodiment of the present disclosure relates to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1. The communication system includes a terminal, an A-IOT device, and a network device. The interactive method may include the following steps:

[0160] Step 2101: The network device configures the first resource and / or the second resource to the terminal.

[0161] In some embodiments, the network device configures a first resource and / or a second resource for the terminal, the first resource is used for the terminal to send a first signal to the A-IOT device, and the second resource is used for the terminal to receive a second signal sent by the A-IOT device.

[0162] In some embodiments, the terminal may determine the first resource and / or the second resource configured by the network device.

[0163] In some embodiments, the manner in which the network device configures the first resource and the second resource is not limited.

[0164] In some embodiments, the manner in which the network device configures the first resource and the second resource is not limited, and the manner in which the first resource and the second resource are configured may be dynamic or semi-static.

[0165] In some embodiments, the first signal may be an energy source (ES) signal, and the ES signal is used to charge the A-IOT device.

[0166] In some embodiments, the first signal may be a downlink transmission (DT) signal, the DT signal including indication information, and the indication information is used to trigger uplink transmission of the A-IOT device.

[0167] In some embodiments, the first signal may be a continuous wave (CW) signal, which may be referred to as an excitation signal. The excitation signal and the CW signal may be used interchangeably in this disclosure. The CW signal is used to trigger uplink transmission of the A-IOT device. In particular, the CW signal may also serve as an energy source to charge the A-IOT device.

[0168] In some embodiments, the second signal may be an uplink transmission (Uplink Receiving, UR) signal sent by the A-IOT device based on backscattering. The uplink transmission and uplink reception in the present disclosure may be used interchangeably.

[0169] In some embodiments, the second signal may be an uplink signal UR actively sent by the A-IOT device.

[0170] Network devices can configure resources for different purposes for terminals. In other words, terminals can determine the resources configured by network devices and use them to perform corresponding sending and receiving operations:

[0171] The terminal may determine a first resource configured by the network device, and the first resource may be used by the terminal to send an ES signal to the A-IOT device.

[0172] The terminal may determine a first resource configured by the network device, and the first resource may be used by the terminal to send a DT signal to the A-IOT device.

[0173] The terminal may determine a first resource configured by the network device, where the first resource may be used by the terminal to send a CW signal to the A-IOT device.

[0174] The terminal can determine the second resource configured by the network device, and the second resource can be used by the terminal to receive the UR signal sent by the A-IOT device.

[0175] In the four examples above, the terminal sending the ES / DT / CW signal can be the same as or different from the terminal receiving the UR signal. The UR signal can be a UR signal sent by the A-IOT device based on backscatter or a UR signal actively sent by the A-IOT device.

[0176] In some embodiments, the terminals sending ES, DT, and CW may be the same or different.

[0177] In some embodiments, the terminal may determine the first resource and / or the second resource in a variety of ways. In other words, step 2101 is optional and may be omitted or replaced in different embodiments.

[0178] For example, the first resource and / or the second resource may be preconfigured, or determined based on the time domain and / or frequency domain resources where the PDSCH or PDCCH is located.

[0179] For example, a network device sends a first message to a terminal. The first message is used to indicate the first resource and / or the second resource. Furthermore, the first message may also be used to indicate the purpose of the first resource and / or the purpose of the second resource. The first message may be an RRC message, a DCI, etc., which is not limited here.

[0180] For example, the first message may include two fields, namely field 1 and field 2, wherein field 1 indicates that the resource is suitable for carrying the first signal or the second signal, and field 2 indicates the location, sequence number or identifier of the resource.

[0181] For example, the network device sends a fourth message or a fifth message to the terminal device, wherein the fourth message is used to indicate the first resource. The fourth message includes field 1 and field 2, wherein field 1 is used to indicate the location, sequence number, or description of the first resource, and field 2 is used to indicate that the first resource is suitable for carrying the first signal. The fifth message is used to indicate the second resource. The fifth message includes field 3 and field 4, wherein field 3 is used to indicate the location, sequence number, or description of the second resource, and field 4 is used to indicate that the second resource is suitable for carrying the second signal.

[0182] Step 2102: The terminal sends a first signal to the A-IOT device through a first resource.

[0183] In some embodiments, the terminal may determine whether the first resource satisfies the first condition.

[0184] The first condition may be pre-configured locally. Alternatively, the first condition may be determined by the second message. The determination of the first condition by the second message can be referred to in the following table. As shown in the following table, the third condition includes Field 4, which is used to determine the first condition.

[0185] In some embodiments, the first resource may be preconfigured or sent by a network device to the terminal.

[0186] In some embodiments, when the terminal determines that the first resource meets the first condition, the first signal is sent to the A-IOT device through the first resource. Conversely, when the terminal determines that the first resource does not meet the first condition, the terminal may request the network device to configure the first resource for the terminal to send the first signal to the A-IOT device.

[0187] In some embodiments, when the first resource meets the first condition, the first signal is sent to the A-IOT device using the first resource. The first condition is that the first resource is mapped to a semi-statically configured flexible Orthogonal Frequency Divisition Multiplexing (OFDM) symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by the slot format indication information (SFI), or an uplink subband UL SB of a full-duplex SBFD symbol with no sub-band overlap. In other words, the resource that the terminal uses to send the first signal to the A-IOT device is a resource that meets the first condition. The first condition is that the first resource overlaps with at least one of the semi-statically configured flexible OFDM symbol, the semi-statically configured uplink OFDM symbol, the uplink OFDM symbol indicated by the SFI, or an uplink subband UL SB of a full-duplex SBFD symbol with no sub-band overlap.

[0188] For example, when the first resource is mapped to a semi-statically configured flexible OFDM symbol, that is, the first resource meets the first condition, the terminal can use the flexible OFDM symbol to send an ES signal to the A-IOT device.

[0189] For example, when the first resource is mapped to a semi-statically configured uplink OFDM symbol, that is, the first resource meets the first condition, the terminal may use the uplink OFDM symbol to send a CW signal to the A-IOT device.

[0190] For example, when the first resource is mapped to the uplink OFDM symbol indicated by the SFI, that is, the first resource meets the first condition, the terminal can use the uplink OFDM symbol to send a DT signal to the A-IOT device.

[0191] For example, when the first resource is mapped to an uplink subband UL SB whose sub-band does not overlap with a full-duplex SBFD symbol, that is, the first resource meets the first condition, the terminal can use the uplink subband UL SB to send a DT signal to the A-IOT device.

[0192] Example 1:

[0193] For example, the resources for the terminal to send ES, CW or DT can be mapped to a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by the slot format indication information (SFI) or the ULSB of the SBFD symbol within a time slot, and the terminal can send a first signal to the A-IOT device through these symbols.

[0194] Example 2:

[0195] For example, the resources used by the terminal to transmit ES, CW, or DT can be mapped to a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by the SFI, or a ULSB of an SBFD symbol within a time slot. In addition, part or all of the ES, CW, and DT resources can also be mapped to other types of OFDM symbols or SBs within a time slot.

[0196] In some embodiments, the resources used by the A-IOT device for receiving and the resources used by the terminal for sending have a mapping relationship or a corresponding relationship, and the resources used by the A-IOT device for sending and the resources used by the terminal for receiving have a mapping relationship or a corresponding relationship.

[0197] Among them, the first resources are the resources used by the A-IOT device for receiving and the resources used by the terminal for sending, and the second resources are the resources used by the A-IOT device for sending and the resources used by the terminal for receiving.

[0198] The AIOT device can determine the first resource and the second resource in a variety of ways, which are not limited here. For example, there is a mapping relationship between the first resource and the second resource. When the AIOT device receives the first signal on the first resource, it can determine the second resource.

[0199] In the above two examples, the resource types available to the terminal may be predefined by the protocol, wherein the resource types may be time domain and / or frequency domain resources.

[0200] Step 2103: The terminal performs a first operation.

[0201] The terminal may determine whether the first resource satisfies the second condition.

[0202] In some embodiments, when the first resource satisfies the second condition, the first operation is performed.

[0203] The first operation performed by the terminal may be different depending on the second condition; that is, the terminal may perform different operations depending on the first resource. The second condition may be pre-configured locally. Alternatively, the second condition may be determined by a third message. The third message may be determined based on different scenarios in the following examples.

[0204] The following describes the execution process when the second condition is different through different examples:

[0205] Regarding Example 1 of step 2102, several situations are described in detail below, namely Example 1 to Example 5 below:

[0206] Example 1:

[0207] In some embodiments, the second condition is: the first resource overlaps with a semi-statically configured downlink OFDM symbol, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the OFDM symbol that meets the second condition; processing it as an error situation.

[0208] For example, when the resources for sending ES, CW or DT by the terminal overlap with the semi-statically configured downlink OFDM symbols, one of the following operations can be performed: canceling the transmission of the first signal in the overlapping time slot; canceling the transmission of the first signal in the overlapping OFDM symbol; treating it as an error situation.

[0209] Example 2:

[0210] In some embodiments, the second condition is: the first resource overlaps with the downlink OFDM symbol indicated by the SFI, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the OFDM symbol that meets the second condition; processing it as an error situation.

[0211] For example, when the resources sending ES, CW or DT by the terminal overlap with the downlink OFDM symbol indicated by SFI, one of the following operations can be performed: canceling the transmission of the first signal in the overlapping time slot; canceling the transmission of the first signal in the overlapping OFDM symbol; treating it as an error situation.

[0212] Example 3:

[0213] In some embodiments, the second condition is that the first resource overlaps with a flexible OFDM symbol indicated by the SFI. The first operation includes any one of the following: canceling the transmission of the first signal in the time slot that meets the second condition; canceling the transmission of the first signal in the OFDM symbol that meets the second condition; sending the first signal to the A-IOT device using the first resource; or handling the situation as an error.

[0214] For example, when the resources for sending ES, CW or DT by the terminal overlap with the flexible OFDM symbol indicated by SFI, one of the following operations can be performed: canceling the transmission of the first signal in the time slot where the overlap occurs; canceling the transmission of the first signal in the OFDM symbol where the overlap occurs; still performing the transmission of the first signal, that is, the flexible OFDM symbol can also be used for signal transmission; or treating it as an error situation.

[0215] Example 4:

[0216] In some embodiments, the second condition is that the first resource does not overlap with a semi-statically configured sub-band or a downlink sub-band (DL SB) of a full-duplex SBFD symbol. The first operation includes any of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the DL SB within the SBFD symbol that meets the second condition; canceling the first signal transmission in the SBFD symbol that meets the second condition; or handling the situation as an error.

[0217] For example, when the terminal sends ES, CW or DT resources that overlap with the downlink subband DL SB of the semi-statically configured sub-band non-overlapping full-duplex SBFD symbol, one of the following operations can be performed: canceling the transmission of the first signal in the overlapping time slot; canceling the transmission of the first signal in the overlapping SBFD symbol; canceling the transmission of the first signal in the overlapping part, that is, canceling the transmission of the first signal of the overlapping DL SB; processing it as an error situation.

[0218] Example 5:

[0219] In some embodiments, the second condition is that the first resource does not overlap with a dynamically indicated sub-band in a downlink sub-band (DL SB) of a full-duplex SBFD symbol. The first operation includes any of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the DL SB in the SBFD symbol that meets the second condition; canceling the first signal transmission in the SBFD symbol that meets the second condition; or handling the situation as an error.

[0220] For example, when the resource sending ES, CW or DT by the terminal overlaps with the downlink subband DL SB of the full-duplex SBFD symbol whose sub-band does not overlap with the dynamically indicated one, one of the following operations can be performed: canceling the transmission of the first signal in the overlapping time slot; canceling the transmission of the first signal in the overlapping SBFD symbol; canceling the transmission of the first signal in the overlapping part, that is, canceling the transmission of the first signal of the overlapping DL SB; or treating it as an error situation.

[0221] Regarding Example 2 of step 2102, several situations are described in detail below, namely Example 6 to Example 10 below:

[0222] Example 6:

[0223] In some embodiments, the second condition is: the first resource overlaps with a semi-statically configured downlink OFDM symbol, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the OFDM symbol that meets the second condition; using the first resource to send the first signal to the A-IOT device; handling it as an error situation.

[0224] For example, when the resources for sending ES, CW or DT by the terminal overlap with the semi-statically configured downlink OFDM symbol, one of the following operations can be performed: canceling the transmission of the first signal in the time slot where the overlap occurs; canceling the transmission of the first signal in the OFDM symbol where the overlap occurs; still performing signal transmission, that is, the terminal can send the first signal using the downlink OFDM symbol; or treating it as an error situation.

[0225] Example 7:

[0226] In some embodiments, the second condition is: the first resource overlaps with the downlink OFDM symbol indicated by the SFI, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the OFDM symbol that meets the second condition; using the first resource to send the first signal to the A-IOT device; handling it as an error situation.

[0227] For example, when the resources for sending ES, CW or DT by the terminal overlap with the downlink OFDM symbol indicated by SFI, one of the following operations can be performed: canceling the transmission of the first signal in the time slot where the overlap occurs; canceling the transmission of the first signal in the OFDM symbol where the overlap occurs; still performing the transmission of the first signal, that is, the terminal can send the first signal using the downlink OFDM symbol; or treating it as an error situation.

[0228] Example 8:

[0229] In some embodiments, the second condition is: the first resource overlaps with the flexible OFDM symbol indicated by the SFI, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the OFDM symbol that meets the second condition; using the first resource to send the first signal to the A-IOT device; handling it as an error situation.

[0230] For example, when the resources for sending ES, CW or DT by the terminal overlap with the flexible OFDM symbol indicated by SFI, one of the following operations can be performed: canceling the transmission of the first signal in the time slot where the overlap occurs; canceling the transmission of the first signal in the OFDM symbol where the overlap occurs; still performing the transmission of the first signal, that is, the terminal can send the first signal using the flexible OFDM symbol; or treating it as an error situation.

[0231] Example 9:

[0232] In some embodiments, the second condition is: the first resource overlaps with the DL SB of the semi-statically configured SBFD symbol, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the SBFD symbol that meets the second condition; canceling the first signal transmission of the DL SB of the SBFD symbol that meets the second condition; using the first resource to send the first signal to the A-IOT device; handling it as an error situation.

[0233] For example, when the resources of ES, CW or DT sent by the terminal overlap with the DL SB of the semi-statically configured SBFD symbol, one of the following operations can be performed: canceling the transmission of the first signal in the time slot where the overlap occurs; canceling the transmission of the first signal in the SBFD symbol where the overlap occurs; canceling the transmission of the first signal in the overlapping part, that is, canceling the transmission of the first signal of the overlapping DL SB; still performing the transmission of the first signal, that is, the DL SB can also be used to send the first signal; processing it as an error situation.

[0234] Example 10:

[0235] In some embodiments, the second condition is: the first resource overlaps with the DL SB of the dynamically indicated SBFD symbol, and the first operation includes any one of the following: canceling the first signal transmission in the time slot that meets the second condition; canceling the first signal transmission in the SBFD symbol that meets the second condition; canceling the first signal transmission of the DL SB of the SBFD symbol that meets the second condition; using the first resource to send the first signal to the A-IOT device; handling it as an error situation.

[0236] For example, when the resources for sending ES, CW or DT by the terminal overlap with the DL SB of the dynamically indicated SBFD symbol, one of the following operations can be performed: canceling the transmission of the first signal in the time slot where the overlap occurs; canceling the transmission of the first signal in the SBFD symbol where the overlap occurs; canceling the transmission of the first signal in the overlapping part, that is, canceling the transmission of the first signal of the overlapping DL SB; still performing the transmission of the first signal, that is, the DL SB can also be used to send the first signal; treating it as an error situation.

[0237] Optionally, for the several exceptions of Example 1 and Example 2 above, in some embodiments, resources may be grouped according to their configuration type or usage. For example, if the first resource meets the second condition and belongs to the first group, the first operation is performed.

[0238] 1) Group by resource configuration type:

[0239] In some embodiments, the first group may be a semi-statically configured time slot or OFDM symbol; a dynamically configured time slot or OFDM symbol.

[0240] In other words, dynamically configured resources can be grouped as a group, and semi-statically configured resources can be grouped as a group. For resources in the same group, the same approach can be adopted when resource conflicts occur. For example, for the first resource of the semi-static configuration, when a resource conflict occurs, the approach of "treating it as an error situation" is adopted.

[0241] 2) Group by resource usage:

[0242] In some embodiments, the first group may be resources for transmitting ES signals, resources for transmitting DT signals, or resources for transmitting CW signals.

[0243] In other words, the resources for sending ES signals can be regarded as a group, the resources for sending DT signals can be regarded as a group, and the resources for sending CW signals can be regarded as a group. For the resources in the same group, the same method can be adopted in the event of resource conflict. For example, for the first resource used to send ES, in the event of resource conflict, the method of "canceling the first signal transmission of the DL SB of the SBFD symbol that meets the second condition" is adopted.

[0244] For example, when processing the conflict between resources and OFDM symbols within a time slot, it is possible to not distinguish between semi-statically configured and dynamically configured resources, or to distinguish between semi-statically configured and dynamically configured resources. That is, the above-mentioned conflict handling method can be that different processing methods are used for dynamic configuration and semi-static configuration, or the same processing method is used for dynamic configuration and semi-static configuration resources.

[0245] For example, while distinguishing or not distinguishing between semi-statically configured and dynamically configured resources, they can also be grouped according to the different transmitted signals. Multiple of the aforementioned ES, CW, and DT resources can be processed using the same method. For example, CW and DT can be processed using the same method. Alternatively, ES, CW, and DT resources can always be processed using the same method. Alternatively, ES, CW, and DT resources can each be processed using different methods.

[0246] In the above embodiment, when the terminal can only send the first signal on the uplink or flexible OFDM symbol, when the first resource configured by the network device overlaps with the downlink or flexible OFDM symbol, the terminal can choose to cancel the signal transmission in the overlapping time slot or cancel the overlapping OFDM transmission signal, or continue to send on the flexible OFDM, or treat it as an error situation; when the first resource overlaps with the DL SB of the semi-statically configured SBFD symbol or the DL SB of the dynamically indicated SBFD symbol, the terminal can choose to cancel the transmission of the first signal in the overlapping time slot, cancel the transmission of the first signal in the overlapping SBFD symbol, cancel the transmission of the first signal in the overlapping DL SB, or send the first signal on the DL SB, or treat it as an error situation. At the same time, the terminal can also group according to dynamic configuration or semi-static configuration and ES, CW, and DT signals, and select different processing methods for different groups or select the same processing method.

[0247] Step 2104: The terminal uses the second resource to receive the second signal sent by the A-IOT device.

[0248] In some embodiments, the terminal may be a device supporting an uplink receiving function, which can receive an uplink signal UR sent by the A-IOT based on backscattering or actively sent.

[0249] In some embodiments, the terminal may be a device that does not support an uplink receiving function, and the uplink signal UR sent by the A-IOT device based on backscattering or actively sent can only be received by a first device other than the terminal.

[0250] For example, the A-IOT device may backscatter and send an uplink signal UR based on a CW signal sent by the terminal. In other words, the terminal needs to send a CW signal to the A-IOT device to trigger the A-IOT device to backscatter the uplink signal UR.

[0251] For example, the A-IOT device may actively send the uplink signal UR. In other words, the terminal does not send a CW signal to the A-IOT device, but the A-IOT device may actively send the uplink signal UR to the terminal.

[0252] In some embodiments, the terminal may determine whether the second resource satisfies a third condition.

[0253] The third condition may be pre-configured locally, or the third condition may be determined by a fourth message. The fourth message may be different conditions in the following examples.

[0254] In some embodiments, the terminal may receive the second signal using the second resource under a different third condition.

[0255] In some embodiments, the second resource may be preconfigured or sent by the network device to the terminal.

[0256] In some embodiments, when the terminal determines that the second resource meets the third condition, the second signal sent by the A-IOT device is received through the second resource. Conversely, when the terminal determines that the second resource does not meet the third condition, the terminal may request the network device to configure the second resource for the terminal to receive the second signal sent by the A-IOT device.

[0257] The following specifically describes the process of receiving the second signal under different third conditions through examples.

[0258] Regarding Example 1 of step 2102, several situations are described in detail below, namely Example 1 to Example 4 below:

[0259] Example 1:

[0260] In some embodiments, if the second resource satisfies a third condition, the second signal is received using the second resource. The third condition is that the second resource is mapped to a semi-statically configured downlink OFDM symbol, a semi-statically configured flexible OFDM symbol, a downlink OFDM symbol indicated by the SFI, or a downlink subband DL SB with non-overlapping subbands of full-duplex SBFD symbols. In other words, the third condition is that the second resource overlaps with at least one of the semi-statically configured downlink OFDM symbol, the semi-statically configured flexible OFDM symbol, the downlink OFDM symbol indicated by the SFI, or a downlink subband DL SB with non-overlapping subbands of full-duplex SBFD symbols.

[0261] For example, when the second resource is mapped to a semi-statically configured flexible OFDM symbol, that is, the second resource meets the third condition, the terminal can use the flexible OFDM symbol to receive the UR signal sent by the A-IOT device.

[0262] For example, when the second resource is mapped to a semi-statically configured downlink OFDM symbol, that is, the second resource meets the third condition, the terminal can use the downlink OFDM symbol to receive the UR signal sent by the A-IOT device.

[0263] For example, when the second resource is mapped to the downlink OFDM symbol indicated by the SFI, that is, the second resource meets the third condition, the terminal can use the downlink OFDM symbol to receive the UR signal sent by the A-IOT device.

[0264] For example, when the second resource is mapped to a downlink sub-band DL SB whose sub-band does not overlap with a full-duplex SBFD symbol, that is, the second resource meets the third condition, the terminal can use the downlink sub-band DL SB to receive the UR signal sent by the A-IOT device.

[0265] For example, the terminal may support receiving the uplink signal backscattered by the A-IOT device on the downlink subband DL SB of the semi-statically configured downlink OFDM symbol, the semi-statically configured flexible OFDM symbol, the downlink OFDM symbol indicated by the SFI, or the full-duplex SBFD symbol with non-overlapping subbands. Using this method, the terminal can receive the backscattered signal of the CW sent by other devices, such as the base station on the OFDM symbol. Within the DLSB, the backscattered signal of the A-IoT device received by the terminal may originate from other devices, such as the CW sent by the base station. Alternatively, the A-IoT device may shift the frequency when backscattering the CW, that is, when the CW is located in the ULSB, the backscattered signal of the A-IoT device may still be located in the DLSB. Using this method, the backscattered signal of the A-IoT device received by the terminal may originate from the UE. In the ULSB of a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by slot format indication information (SFI), or an SBFD symbol, other devices, such as a base station, are used to receive the uplink signal backscattered by the A-IoT device based on the CW of the terminal.

[0266] Example 2:

[0267] In some embodiments, if the second resource satisfies a third condition, the second signal is received using the second resource. The third condition is that the second resource is mapped to a semi-statically configured uplink OFDM symbol, a semi-statically configured flexible OFDM symbol, an uplink OFDM symbol indicated by the SFI, or an uplink subband UL SB with non-overlapping subbands of full-duplex SBFD symbols. In other words, the third condition is that the second resource overlaps with at least one of the semi-statically configured uplink OFDM symbol, the semi-statically configured flexible OFDM symbol, the uplink OFDM symbol indicated by the SFI, or an uplink subband UL SB with non-overlapping subbands of full-duplex SBFD symbols.

[0268] For example, the terminal may support receiving the second signal backscattered by the A-IOT device, that is, the uplink signal UR, that is, the terminal may receive the uplink signal UR of the A-IOT device on a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by SFI, or an uplink sub-band UL SB of a full-duplex SBFD symbol with non-overlapping sub-bands.

[0269] Example 3:

[0270] In some embodiments, if the second resource satisfies a third condition, the second signal is received using the second resource. The third condition is that the second resource is mapped to a semi-statically configured uplink OFDM symbol, a semi-statically configured flexible OFDM symbol, an uplink OFDM symbol indicated by the SFI, or an uplink subband DL SB with non-overlapping subbands of full-duplex SBFD symbols. In other words, the third condition is that the second resource overlaps with at least one of the semi-statically configured uplink OFDM symbol, the semi-statically configured flexible OFDM symbol, the uplink OFDM symbol indicated by the SFI, or an uplink subband DL SB with non-overlapping subbands of full-duplex SBFD symbols.

[0271] For example, a terminal may support receiving uplink signals backscattered by an A-IOT device on a DL SB of an SBFD symbol. Within a DL SB, the backscattered signal from the A-IOT device received by the terminal may originate from another device, such as a CW transmitted by a base station. Alternatively, the A-IOT device may shift the frequency when backscattering the CW. That is, when the CW is located on the UL SB, the backscattered signal from the A-IOT device may still be located on the DL SB.

[0272] Example 4:

[0273] In some embodiments, if the second resource satisfies a third condition, the second signal is received using the second resource. The third condition is that the second resource is mapped to a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by the SFI, an uplink subband (UL SB) with non-overlapping full-duplex SBFD symbol, or a downlink subband (DL SB) with SBFD symbol. In other words, the third condition is that the second resource overlaps with at least one of the following: a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by the SFI, an uplink subband (UL SB) with non-overlapping full-duplex SBFD symbol, or a downlink subband (DL SB) with SBFD symbol.

[0274] For example, the terminal may support receiving the backscattered uplink signal of the A-IOT device on the SBFD symbol, and the backscattered uplink signal may be located in the UL SB or the DL SB.

[0275] Regarding Example 2 of step 2102, several situations are described in detail below, namely Example 5 and Example 6 below:

[0276] Example 5:

[0277] In some embodiments, if the second resource satisfies a third condition, the second signal is received using the second resource. The third condition is that the second resource is mapped to a semi-statically configured downlink OFDM symbol, a semi-statically configured flexible OFDM symbol, a downlink OFDM symbol indicated by the SFI, or a DL SB of an SBFD symbol. In other words, the third condition is that the second resource overlaps with at least one of the semi-statically configured downlink OFDM symbol, the semi-statically configured flexible OFDM symbol, the downlink OFDM symbol indicated by the SFI, or a DL SB of an SBFD symbol.

[0278] For example, the terminal may support receiving the second signal backscattered by the A-IOT device, i.e., the uplink signal, on a DL SB of a semi-statically configured downlink OFDM symbol, a semi-statically configured flexible OFDM symbol, a downlink OFDM symbol indicated by an SFI, or an SBFD symbol. For other types of OFDM symbols within a time slot, the terminal may use other methods to process UR resources.

[0279] Example 6:

[0280] In some embodiments, if the second resource satisfies a third condition, the second signal is received using the second resource. The third condition is that the second resource is mapped to a semi-statically configured uplink OFDM symbol, a semi-statically configured flexible OFDM symbol, or an uplink OFDM symbol indicated by the SFI. In other words, the third condition is that the second resource overlaps with at least one of the semi-statically configured uplink OFDM symbol, the semi-statically configured flexible OFDM symbol, and the uplink OFDM symbol indicated by the SFI.

[0281] For example, the terminal may support receiving the second signal, i.e., the uplink signal, backscattered by the A-IOT device on a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, or an uplink OFDM symbol indicated by the SFI. For other types of OFDM symbols within a time slot, the terminal may use other methods to process UR resources.

[0282] Step 2105: The terminal performs a second operation.

[0283] In some embodiments, the terminal may determine whether the second resource satisfies a fourth condition.

[0284] In some embodiments, the terminal performs the second operation if the second resource meets the fourth condition.

[0285] If the fourth condition is different, the second operation performed by the terminal may be different, that is, when the second resource is different, the terminal performs a different operation. The fourth condition may be pre-configured locally. Alternatively, the fourth condition may be determined by a fifth message. The fifth message may have different content.

[0286] The following specifically describes the process of performing the second operation when the fourth condition is different by taking an example.

[0287] Regarding Example 1 of step 2102, several situations are described in detail below, namely Example 1 to Example 4 below:

[0288] Example 1:

[0289] In some embodiments, the fourth condition is that the second resource overlaps with a semi-statically configured uplink OFDM symbol; the second operation includes any one of the following: canceling the second signal transmission in the time slot that meets the fourth condition; canceling the second signal transmission in the OFDM symbol that meets the fourth condition; processing it as an error situation.

[0290] For example, when the resource for receiving the UR signal by the terminal overlaps with the semi-statically configured uplink OFDM symbol, one of the following operations can be performed: cancel the second signal transmission in the time slot where the overlapping part occurs, that is, receive the uplink transmission of A-IOT; cancel the second signal transmission in the overlapping OFDM symbol, that is, receive the uplink transmission of A-IOT; treat it as an error situation.

[0291] In some embodiments, the fourth condition is that the second resource overlaps with the uplink OFDM symbol indicated by the SFI; the second operation includes any one of the following: canceling the second signal transmission in the time slot that meets the fourth condition; canceling the second signal transmission in the OFDM symbol that meets the fourth condition; processing it as an error situation.

[0292] For example, when the resource for receiving the UR signal by the terminal overlaps with the uplink OFDM symbol indicated by the SFI, one of the following operations can be performed: canceling the second signal transmission of A-IOT received in the time slot where the overlapping part occurs, that is, the uplink transmission; canceling the second signal transmission of A-IOT received in the overlapping part, that is, the uplink transmission, that is, canceling the second signal transmission of A-IOT received in the overlapping OFDM symbol, that is, the uplink transmission; treating it as an error situation.

[0293] In some embodiments, the fourth condition is that the second resource overlaps with the flexible OFDM symbol indicated by the SFI; the fourth operation includes any one of the following: canceling the second signal transmission in the time slot that meets the fourth condition; canceling the second signal transmission in the OFDM symbol that meets the fourth condition; receiving the second signal using the second resource; processing as an error situation.

[0294] For example, when the resource for receiving the UR signal by the terminal overlaps with the flexible OFDM symbol indicated by the SFI, one of the following operations can be performed: canceling the second signal transmission of A-IOT received in the time slot where the overlap occurs, that is, the uplink transmission; canceling the uplink transmission of A-IOT received in the overlapping part, that is, canceling the second signal transmission of A-IOT received in the overlapping OFDM symbol, that is, the uplink transmission; still receiving the uplink transmission of the A-IOT device, that is, the flexible OFDM symbol can also receive the uplink transmission of the A-IOT device; treating it as an error situation.

[0295] In some embodiments, the fourth condition is that the second resource overlaps with the UL SB of the semi-statically configured SBFD symbol; the fourth operation includes any one of the following: canceling the second signal transmission in the time slot that meets the fourth condition; canceling the second signal transmission in the SBFD symbol that meets the fourth condition; canceling the second signal transmission of the UL SB in the SBFD symbol that meets the fourth condition; processing as an error situation.

[0296] For example, when the resource for receiving the UR signal of the terminal overlaps with the UL SB of the semi-statically configured SBFD symbol, one of the following operations can be performed: canceling the uplink transmission of A-IOT received in the time slot where the overlap occurs, that is, the transmission of the second signal; canceling the uplink transmission of A-IOT received in the overlapping SBFD symbol, canceling the uplink transmission of A-IOT received in the overlapping part, that is, canceling the second signal transmission of A-IOT received in the overlapping UL SB; processing it as an error situation.

[0297] In some embodiments, the fourth condition is that the second resource overlaps with the UL SB of the dynamically indicated SBFD symbol; the fourth operation includes any one of the following: canceling the second signal transmission in the time slot that meets the fourth condition; canceling the second signal transmission in the SBFD symbol that meets the fourth condition; canceling the second signal transmission of the UL SB in the SBFD symbol that meets the fourth condition; processing as an error situation.

[0298] For example, when the resource for receiving the UR signal of the terminal overlaps with the UL SB of the semi-statically configured SBFD symbol, one of the following operations can be performed: canceling the uplink transmission of A-IOT received in the time slot where the overlap occurs, that is, the transmission of the second signal; canceling the uplink transmission of A-IOT received in the overlapping SBFD symbol, canceling the uplink transmission of A-IOT received in the overlapping part, that is, canceling the second signal transmission of A-IOT received in the overlapping UL SB; processing it as an error situation.

[0355] For example, when the resource for receiving the UR signal of the terminal overlaps with the semi-statically configured SBFD symbol, one of the following operations can be performed: canceling the uplink transmission of A-IOT received in the time slot of the overlapping part, that is, the transmission of the second signal; canceling the uplink transmission of A-IOT received in the overlapping SBFD symbol, that is, canceling the second signal transmission in the overlapping SBFD symbol; canceling the uplink transmission of A-IOT received in the overlapping part of DL SB, that is, canceling the second signal transmission in the overlapping DL SB; canceling the uplink transmission of A-IOT received in the overlapping part of UL SB, that is, canceling the second signal transmission in the overlapping UL SB; still receiving the uplink transmission of the A-IOT device, that is, the terminal supports receiving the uplink transmission of the A-IOT device on the UL SB; and handling it as an error situation.

[0357] For example, when the resource for receiving the UR signal of the terminal overlaps with the semi-statically configured SBFD symbol, one of the following operations can be performed: canceling the uplink transmission of A-IOT received in the time slot of the overlapping part, that is, the transmission of the second signal; canceling the uplink transmission of A-IOT received in the overlapping SBFD symbol, that is, canceling the second signal transmission in the overlapping SBFD symbol; canceling the uplink transmission of A-IOT received in the overlapping part of DL SB, that is, canceling the second signal transmission in the overlapping DL SB; canceling the uplink transmission of A-IOT received in the overlapping part of UL SB, that is, canceling the second signal transmission in the overlapping UL SB; still receiving the uplink transmission of the A-IOT device, that is, the terminal supports receiving the uplink transmission of the A-IOT device on the UL SB; and handling it as an error situation.

[0358] Optionally, with respect to the above example, in some embodiments, resources may be grouped according to their configuration type or resource usage. For example, when the second resource meets the fourth condition and belongs to the first group, the second operation is performed.

[0359] For example, when the second resource meets the fourth condition and belongs to the first group, the second operation is performed, that is, different groups may select different processing methods or the same processing method.

[0360] 1) Group by resource configuration type:

[0361] In some embodiments, the first group may be a semi-statically configured time slot or OFDM symbol; a dynamically configured time slot or OFDM symbol.

[0362] In other words, dynamically configured resources can be grouped as a group, and semi-statically configured resources can be grouped as a group. For resources in the same group, the same method can be adopted in the event of resource conflicts. For example, for the first resource configured semi-statically, in the event of resource conflicts, the method of "canceling the second signal transmission in the time slot that meets the fourth condition" is adopted.

[0363] 2) Group by resource usage:

[0364] In some embodiments, the first group may be resources for sending ES signals, resources for sending DT signals, resources for sending CW signals, and resources for receiving UR signals.

[0365] In other words, the resources for sending ES signals can be regarded as a group, the resources for sending DT signals can be regarded as a group, the resources for sending CW signals can be regarded as a group, and the resources for receiving UR signals can be regarded as a group. For the resources in the same group, the same method can be adopted in the event of resource conflict. For example, for the second resource used to receive UR ​​signals, in the event of resource conflict, the method of "canceling the second signal transmission of the DL SB of the SBFD symbol that meets the fourth condition" is adopted.

[0366] For example, when processing the conflict between the second resource and the OFDM symbol in the time slot, it can be that the resources with semi-static configuration and dynamic configuration are not distinguished, or the resources with semi-static configuration and dynamic configuration are distinguished. That is, the above-mentioned conflict handling method can be that different processing methods are used for dynamic configuration and semi-static configuration, or the same processing method is used for dynamic configuration and semi-static configuration.

[0367] For example, while distinguishing or not distinguishing between semi-statically configured and dynamically configured resources, they can also be grouped according to the difference between transmitted and received signals. Multiple of the aforementioned ES, CW, DT, and UR resources can be processed using the same method. For example, CW and UR can be processed using the same method. Alternatively, ES, CW, and DT resources can always be processed using the same method. Alternatively, ES, CW, DT, and UR resources can always be processed using the same method. Alternatively, ES, CW, DT, and UR resources can each be processed using a different method.

[0368] In the above embodiment, when a terminal receives a second signal on an uplink, downlink, or flexible OFDM symbol, and a second resource configured by a network device overlaps with a downlink or flexible OFDM symbol, the terminal can choose to cancel receiving the overlapping time slot signal, cancel receiving the overlapping OFDM signal, continue receiving on the second resource, or treat it as an error. Furthermore, the terminal can group signals according to dynamic or semi-static configuration and ES, CW, DT, or UR signals, and select different processing methods or the same processing method for different groups.

[0369] In the above embodiment, when the first and second resources configured by the network device for the terminal overlap with uplink, downlink, or flexible OFDM symbols, the terminal can select different processing methods based on different situations to resolve the conflict between the signal transmission between the terminal and the A-IOT device and the uplink and downlink OFDM symbols. In some embodiments, the use of the first resource to send a CW signal to the A-IOT device and the use of the second resource to receive the UR signal sent by the A-IOT device can be in the same time period or in different time periods.

[0370] For example, a terminal can be used only to transmit CWs or only to receive uplink signals UR from A-IOT devices at any given time. For example, terminal 1 transmits a CW to an A-IOT device, while terminal 2 receives the uplink signal UR backscattered by the A-IOT device based on the CW, i.e., half-duplex. Alternatively, a terminal can simultaneously transmit CWs and receive uplink signals UR from A-IOT devices, i.e., full-duplex.

[0371] In the above embodiment, step 2102, step 2103 and step 2104, step 2105 can be executed simultaneously or separately.

[0372] In some embodiments, during a first time period, a CW signal is sent to an A-IOT device using a first resource, and a UR signal sent by the A-IOT device is received using a second resource.

[0373] In some embodiments, during a first time period, a CW signal is sent to an A-IOT device using a first resource.

[0374] In some embodiments, during the first time period, a second resource is used to receive a UR signal sent by the A-IOT device.

[0375] The communication method according to the embodiments of the present disclosure may include at least one of steps 2101 to 2105. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and so on, but the present invention is not limited thereto. Steps 2101+2102, step 2101+2102+2103, step 2101+2102+2104, step 2101+2102+2103+2104, step 2101+2102+2104+2105, and step 2101+2102+2103+2104+2105 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0412] The following are specific solutions provided by the embodiments of the present disclosure:

[0413] To support data transmission between A-IoT devices, the network needs to support the following functions. A device in the network can support one or more functions.

[0414] (1) As an excitation function, it is only used for Devices A and B. The A-IoT device achieves uplink transmission through backscatter CW.

[0415] (2) As an energy source, it can be used for device types B and C. CW is actually also an energy source, and A-IOT devices can receive CW and store energy. For device type A, because the energy storage capacity is very limited, ES signals other than CW can be undefined. Alternatively, ES signals can also be used for device type A.

[0416] (3) Downlink transmission function, sending indication information to the A-IoT device, thereby triggering the uplink transmission of the A-IoT device.

[0417] (4) Uplink receiving function, receiving uplink information backscattered by A-IoT devices, or receiving uplink information actively transmitted by A-IoT devices.

[0418] In addition to implementing one or more of the above functions, the above-mentioned device can also perform uplink and downlink transmission of the cellular network. For the above-mentioned device, the network needs to coordinate the above-mentioned functions and the resource allocation for uplink and downlink transmission on the cellular network. The resource allocation for uplink and downlink transmission on the cellular network can also support sub-band non-overlapping full-duplex (SBFD), that is, within one OFDM symbol, the frequency band used for downlink transmission (UL SB) and the frequency band for uplink reception (DL SB) are frequency division multiplexed. The device that performs one or more of the above-mentioned ES, DT, CW or UR functions can be a UE. The ES, DT, CW or UR resources of the UE can be semi-statically configured or dynamically indicated. In particular, one channel or signal can support both ES and CW functions at the same time, so that only resource configuration needs to be performed on the one channel or signal.

[0419] Example 1:

[0420] The ES, CW or DT resources of the UE can be mapped to the semi-statically configured flexible OFDM symbols, semi-statically configured uplink OFDM symbols, uplink OFDM symbols indicated by the slot format indication information (SFI), or UL SB of the SBFD symbol within a time slot. For other types of OFDM symbols or SBs within a time slot, the UE can process any of the ES, CW and DT resources using the following method:

[0421] 1. If the signal overlaps with the semi-statically configured downlink OFDM symbol, one of the following processing methods may be used: cancel the transmission of the signal in the time slot where the overlap occurs; cancel the transmission of the signal in the overlapping part; or treat it as an error case.

[0422] 2. If the signal overlaps with the downlink OFDM symbol indicated by the SFI, one of the following processing methods may be used: canceling the transmission of the signal in the time slot where the overlap occurs; canceling the transmission of the signal in the overlapping part; or treating it as an error case.

[0423] 3. If there is overlap with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be adopted: cancel the transmission of the one signal in the time slot where the overlap occurs; cancel the transmission of the one signal in the overlapping part; still perform the transmission of the one signal, that is, the flexible OFDM symbol can also be used for the one signal; handle it as an error case.

[0424] 4. If a DL SB overlaps with a semi-statically configured SBFD symbol, one of the following processing methods may be used: canceling the transmission of the signal in the time slot where the overlap occurs; canceling the transmission of the signal in the overlapping SBFD symbol; canceling the transmission of the signal in the overlapping part; or treating it as an error case.

[0425] 5. If a DL SB overlaps with a dynamically indicated SBFD symbol, one of the following processing methods may be used: canceling the transmission of the signal in the time slot where the overlap occurs; canceling the transmission of the signal in the overlapping SBFD symbol; canceling the transmission of the signal in the overlapping part; or treating it as an error case.

[0426] When handling conflicts between the ES, DT, and CW resources and OFDM symbols within a time slot, one of the aforementioned processing methods may be defined for each of the ES, CW, and DT resources, regardless of whether the resources are semi-statically configured or dynamically indicated. Alternatively, a distinction may be made between semi-statically configured and dynamically indicated resources, and one of the aforementioned processing methods may be further defined for each of the ES, CW, and DT resources. The same processing method may be used for multiple types of the ES, CW, and DT resources. For example, the same method may be used for CW and DT resources. Alternatively, the same method may always be used for ES, CW, and DT resources.

[0427] A UE may not support receiving the uplink signal UR backscattered by the A-IoT device. Using this method, other devices, such as base stations, are used to receive the uplink signal UR backscattered by the A-IoT device based on the CW of the UE.

[0428] A UE may support receiving the uplink signal backscattered by an A-IoT device on a DL SB of a semi-statically configured downlink OFDM symbol, a semi-statically configured flexible OFDM symbol, a downlink OFDM symbol indicated by an SFI, or an SBFD symbol. Using this method, the UE may receive the backscattered signal of a CW sent by another device, such as a base station, on the OFDM symbol within the semi-statically configured downlink OFDM symbol, the semi-statically configured flexible OFDM symbol, or the downlink OFDM symbol indicated by an SFI. Within the DL SB, the backscattered signal of the A-IoT device received by the UE may originate from another device, such as a CW sent by a base station. Alternatively, the A-IoT device may shift the frequency when backscattering the CW, that is, when the CW is located in the UL SB, the backscattered signal of the A-IoT device may still be located in the DL SB. Using this method, the backscattered signal of the A-IoT device received by the UE may originate from the UE. In the UL SB of a semi-statically configured flexible OFDM symbol, a semi-statically configured uplink OFDM symbol, an uplink OFDM symbol indicated by the slot format indication information (SFI), or an SBFD symbol, other devices, such as a base station, are used to receive the uplink signal backscattered by the A-IoT device based on the CW of the UE. For other types of OFDM symbols or SBs in a time slot, the UE can use the following method to process the UR resources:

[0429] 1. If the uplink OFDM symbol overlaps with the semi-statically configured uplink OFDM symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0430] 2. If the uplink OFDM symbol overlaps with the SFI indicator, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0431] 3. If the symbol overlaps with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the flexible OFDM symbol can also receive the uplink transmission of A-IoT device; handle it as an error case.

[0432] 4. If the UL SB overlaps with the semi-statically configured SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0433] 5. If the UL SB overlaps with the dynamically indicated SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0434] When handling conflicts between UR resources and OFDM symbols within a time slot, one of the above-mentioned unified processing methods may be defined without distinguishing between semi-statically configured and dynamically indicated UR resources. Alternatively, one of the above-mentioned processing methods may be defined separately for semi-statically configured and dynamically indicated UR resources.

[0435] A UE may support receiving an uplink signal UR from an A-IoT device backscattered based on the CW. That is, the UE may receive the uplink signal UR from the A-IoT device in semi-statically configured flexible OFDM symbols, semi-statically configured uplink OFDM symbols, or uplink OFDM symbols indicated by the SFI. The UE may also use one of the following methods to receive the uplink signal from the A-IoT device within an SBFD symbol.

[0436] The first method is that the UE can support receiving the uplink signal of the backscattered A-IoT device on the UL SB of the SBFD symbol. For other types of OFDM symbols or SBs in a time slot, the UE can use one of the following methods to process the UR resources:

[0437] 1. If the overlap occurs with the semi-statically configured downlink OFDM symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0438] 2. If the signal overlaps with the downlink OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0439] 3. If the symbol overlaps with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the flexible OFDM symbol can also receive the uplink transmission of A-IoT device; handle it as an error case.

[0440] 4. If the DL SB overlaps with the semi-statically configured SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0441] 5. If the DL SB overlaps with the dynamically indicated SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0442] The second method is that the UE can support receiving the backscattered uplink signal of the A-IoT device on the DL SB of the SBFD symbol. Within the DL SB, the backscattered signal of the A-IoT device received by the UE may originate from other devices, such as the CW sent by the base station. Alternatively, the A-IoT device can shift the frequency when backscattering the CW, that is, when the CW is located in the UL SB, the backscattered signal of the A-IoT device may still be located in the DL SB. Using this method, the backscattered signal of the A-IoT device received by the UE may originate from the UE. For other types of OFDM symbols or SBs within a time slot, the UE may use one of the following methods to process the UR resources:

[0443] 1. If the overlap occurs with the semi-statically configured downlink OFDM symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0444] 2. If the signal overlaps with the downlink OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0445] 3. If the symbol overlaps with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the flexible OFDM symbol can also receive the uplink transmission of A-IoT device; handle it as an error case.

[0446] 4. If the UL SB overlaps with the semi-statically configured SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0447] 5. If the UL SB overlaps with the dynamically indicated SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0448] The third method is that the UE can support receiving the uplink signal backscattered by the A-IoT device on the SBFD symbol, and the uplink signal backscattered can be located in the UL SB or DL ​​SB. For other types of OFDM symbols and SBFD symbols in a time slot, the UE can use one of the following methods to process the UR resources:

[0449] 1. If the overlap occurs with the semi-statically configured downlink OFDM symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0450] 2. If the signal overlaps with the downlink OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; or treat it as an error case.

[0451] 3. If the symbol overlaps with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the flexible OFDM symbol can also receive the uplink transmission of A-IoT device; handle it as an error case.

[0452] 4. For overlap with semi-statically configured SBFD symbols, one of the following processing methods can be used: cancel the reception of A-IoT uplink transmission in the time slot where the overlap occurs; cancel the reception of A-IoT uplink transmission in the overlapping SBFD symbol; cancel the reception of A-IoT uplink transmission in the overlapping part of DL SB; cancel the reception of A-IoT uplink transmission in the overlapping part of UL SB; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received in the SBFD symbol; handle it as an error case.

[0453] 5. If the symbol overlaps with the dynamically indicated SBFD symbol, one of the following processing methods may be used: cancel the reception of the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the reception of the uplink transmission of A-IoT in the overlapping SBFD symbol; cancel the reception of the uplink transmission of A-IoT in the overlapping part of the DL SB; cancel the reception of the uplink transmission of A-IoT in the overlapping part of the UL SB; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received in the SBFD symbol; or treat it as an error case.

[0454] When processing the conflict between the above-mentioned ES, DT, CW or UR resources and the OFDM symbols in the time slot, it is possible to not distinguish between semi-static configuration and dynamic indication of the resources, and define one of the above-mentioned processing methods for ES, CW, DT or UR resources respectively. Alternatively, it is possible to distinguish between semi-static configuration and dynamic indication of the resources, and further distinguish between ES, CW, DT or UR resources and define one of the above-mentioned processing methods respectively. The same processing method can be used for multiple of the above-mentioned ES, CW, DT or UR resources. For example, CW and UR resources can be processed using the same method. For example, the total number of ES, CW, and DT resources is processed using the same method. For example, ES, CW, DT and UR resources are always processed using the same method.

[0455] Using the above method, a UE can transmit only CWs or only receive uplink signals UR from A-IoT devices for a period of time. For example, UE 1 transmits CWs to an A-IoT device, while UE 2 receives uplink signals from the A-IoT device backscattered from the CWs, i.e., half-duplex. Alternatively, a UE can simultaneously transmit CWs and receive uplink signals from A-IoT devices, i.e., full-duplex.

[0456] Example 2:

[0457] The ES, CW, and DT resources of the UE can be mapped to the semi-statically configured flexible OFDM symbols, semi-statically configured uplink OFDM symbols, uplink OFDM symbols indicated by SFI, or UL SBs of SBFD symbols within a time slot. In addition, part or all of the ES, CW, and DT resources can also be mapped to other types of OFDM symbols or SBs within a time slot. For other types of OFDM symbols or SBs within a time slot, the following method can be used to process any signal of the ES, CW, and DT resources:

[0458] 1. If there is overlap with a semi-statically configured downlink OFDM symbol, one of the following processing methods can be used: cancel the transmission of the one signal in the time slot where the overlap occurs; cancel the transmission of the one signal in the overlapping part; still perform the transmission of the one signal, that is, the downlink OFDM symbol can also be used for the one signal; or handle it as an error case.

[0459] 2. If the signal overlaps with the downlink OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the transmission of the signal in the time slot where the overlap occurs; cancel the transmission of the signal in the overlapping part; still perform the transmission of the signal, that is, the downlink OFDM symbol can also be used for the signal; or treat it as an error case.

[0460] 3. If there is overlap with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be adopted: cancel the transmission of the one signal in the time slot where the overlap occurs; cancel the transmission of the one signal in the overlapping part; still perform the transmission of the one signal, that is, the flexible OFDM symbol can also be used for the one signal; handle it as an error case.

[0461] 4. If a DL SB overlaps with a semi-statically configured SBFD symbol, one of the following processing methods may be used: canceling the transmission of the signal in the time slot where the overlap occurs; canceling the transmission of the signal in the overlapping SBFD symbol; canceling the transmission of the signal in the overlapping portion; still performing the transmission of the signal, i.e., the DL SB can also be used for the signal; or handling the situation as an error case.

[0462] 5. If a DL SB overlaps with a dynamically indicated SBFD symbol, one of the following processing methods may be used: canceling the transmission of the signal in the time slot where the overlap occurs; canceling the transmission of the signal in the overlapping SBFD symbol; canceling the transmission of the signal in the overlapping portion; still performing the transmission of the signal, i.e., the DL SB can also be used for the signal; or handling the situation as an error case.

[0463] When handling conflicts between the ES, DT, and CW resources and OFDM symbols within a time slot, one of the aforementioned processing methods may be defined for each of the ES, CW, and DT resources, regardless of whether the resources are semi-statically configured or dynamically indicated. Alternatively, a distinction may be made between semi-statically configured and dynamically indicated resources, and one of the aforementioned processing methods may be further defined for each of the ES, CW, and DT resources. The same processing method may be used for multiple types of the ES, CW, and DT resources. For example, the same method may be used for CW and DT resources. Alternatively, the same method may always be used for ES, CW, and DT resources.

[0464] A UE may not support receiving the uplink signal UR backscattered by the A-IoT device. Using this method, other devices, such as base stations, are used to receive the uplink signal UR backscattered by the A-IoT device based on the CW of the UE.

[0465] A UE may support receiving the uplink signal backscattered by the A-IoT device on the DL SB of the semi-statically configured downlink OFDM symbol, the semi-statically configured flexible OFDM symbol, the downlink OFDM symbol indicated by SFI, or the SBFD symbol. For other types of OFDM symbols or SBs in a time slot, the UE may process the UR resources in the following manner:

[0466] 1. If the uplink OFDM symbol overlaps with the semi-statically configured uplink OFDM symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the uplink transmission of A-IoT device can also be received on the uplink OFDM symbol; treat it as an error case.

[0467] 2. If the uplink OFDM symbol indicated by SFI overlaps, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the uplink transmission of A-IoT device can also be received on the uplink OFDM symbol; handle it as an error case.

[0468] 3. If the symbol overlaps with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the uplink transmission of A-IoT device can also be received on the flexible OFDM symbol; handle it as an error case.

[0469] 4. If the UL SB overlaps with the semi-statically configured SBFD symbol, one of the following processing methods can be used: cancel the reception of the A-IoT uplink transmission in the time slot where the overlap occurs; cancel the reception of the A-IoT uplink transmission in the overlapping SBFD symbol; cancel the reception of the A-IoT uplink transmission in the overlapping part; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received on the UL SB; handle it as an error case.

[0470] 5. If the UL SB overlaps with the dynamically indicated SBFD symbol, one of the following processing methods can be used: cancel the uplink transmission of A-IoT received in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT received in the overlapping SBFD symbol; cancel the uplink transmission of A-IoT received in the overlapping part; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received on the UL SB; handle it as an error case.

[0471] When handling conflicts between UR resources and OFDM symbols within a time slot, one of the above-mentioned unified processing methods may be defined without distinguishing between semi-statically configured and dynamically indicated UR resources. Alternatively, one of the above-mentioned processing methods may be defined separately for semi-statically configured and dynamically indicated UR resources.

[0472] A UE can support receiving the uplink signal of the backscattered A-IoT device on the semi-statically configured flexible OFDM symbols, the semi-statically configured uplink OFDM symbols, and the uplink OFDM symbols indicated by SFI. The UE can also use one of the following methods to process the uplink signal of the A-IoT device received in the SBFD symbol. For other types of OFDM symbols or SBFD symbols in a time slot, the UE can use one of the following methods to process the UR resources:

[0473] 1. If the signal overlaps with the semi-statically configured downlink OFDM symbol, one of the following processing methods can be used: cancel the reception of the A-IoT uplink transmission in the time slot where the overlap occurs; cancel the reception of the A-IoT uplink transmission in the overlapping part; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received on the downlink OFDM symbol; or treat it as an error case.

[0474] 2. If the data overlaps with the downlink OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the reception of the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the reception of the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received on the downlink OFDM symbol; handle it as an error case.

[0475] 3. If the symbol overlaps with the flexible OFDM symbol indicated by SFI, one of the following processing methods can be used: cancel the uplink transmission of A-IoT in the time slot where the overlap occurs; cancel the uplink transmission of A-IoT in the overlapping part; still receive the uplink transmission of A-IoT device, that is, the flexible OFDM symbol can also receive the uplink transmission of A-IoT device; handle it as an error case.

[0476] 4. If there is overlap with the semi-statically configured SBFD symbol, one of the following processing methods can be used: cancel the reception of the A-IoT uplink transmission in the time slot where the overlap occurs; cancel the reception of the A-IoT uplink transmission in the overlapping SBFD symbol; cancel the reception of the A-IoT uplink transmission in the overlapping part of the DL SB; cancel the reception of the A-IoT uplink transmission in the overlapping part of the UL SB; still receive the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received on the UL SB; handle it as an error case.

[0477] 5. If the symbol overlaps with the dynamically indicated SBFD symbol, one of the following processing methods may be used: canceling the reception of the uplink transmission of A-IoT in the time slot where the overlap occurs; canceling the reception of the uplink transmission of A-IoT in the overlapping SBFD symbol; canceling the reception of the uplink transmission of A-IoT in the overlapping part of the DL SB; canceling the reception of the uplink transmission of A-IoT in the overlapping part of the UL SB; still receiving the uplink transmission of the A-IoT device, that is, the uplink transmission of the A-IoT device can also be received on the UL SB; handling it as an error case.

[0478] When processing the conflict between the above-mentioned ES, DT, CW or UR resources and the OFDM symbols in the time slot, it is possible to not distinguish between semi-static configuration and dynamic indication of the resources, and define one of the above-mentioned processing methods for ES, CW, DT or UR resources respectively. Alternatively, it is possible to distinguish between semi-static configuration and dynamic indication of the resources, and further distinguish between ES, CW, DT or UR resources and define one of the above-mentioned processing methods respectively. Multiple of the above-mentioned ES, CW, DT or UR resources can adopt the same processing method. For example, CW and UR resources can be processed using the same method. For example, ES, CW, DT resources are processed using the same method. For example, ES, CW, DT and UR resources are always processed using the same method.

[0479] Using the above method, for a UE, it is possible to transmit only CW for a period of time, or only receive the uplink signal UR of the A-IoT device. For example, UE 1 transmits CW to the A-IoT device, and at the same time, UE 2 receives the uplink signal of the A-IoT device based on the backscattering of the CW, that is, half-duplex. Alternatively, a UE can simultaneously transmit CW and receive the uplink signal of the A-IoT device, that is, full-duplex. In the embodiments of the present disclosure, some or all of the steps and their optional implementation methods can be arbitrarily combined with some or all of the steps in other embodiments, and can also be arbitrarily combined with the optional implementation methods of other embodiments.
