[0073] 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 modules. 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.

[0074] 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.

[0075] Therefore, the present disclosure proposes a communication method, apparatus, communication equipment, storage medium and communication system, which coordinates the resource allocation of uplink and downlink transmissions of A-IoT devices and other cellular communications by defining a method for handling resource conflicts between the uplink and downlink transmissions of A-IoT devices and other cellular communications, thereby achieving efficient data transmission of A-IOT devices.

[0092] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0093] Step 2101: Terminal 101 performs a first operation when a first resource and a second resource configured for the terminal by a network device overlap.

[0094] In some embodiments, the first resource is used for communication between the terminal and the network device, and the second resource is used for communication between the terminal and the A-IOT device.

[0095] In some embodiments, the manner in which the network device configures the first resource and the second resource is not limited.

[0096] 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.

[0097] In some embodiments, the first resource includes a first uplink resource and / or a first downlink resource, the first uplink resource is used to send a first uplink signal to the network device, and the first downlink resource is used to receive a first downlink signal sent by the network device.

[0098] In some embodiments, the first uplink signal is, for example: a signal transmitted through a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a signal transmitted through a physical uplink control channel (Physical Uplink Control Channel, PUCCH), a sounding reference signal (SRS), a signal transmitted through a physical random access channel (PRACH), etc., which is not limited in the present disclosure.

[0099] In some embodiments, the second resource includes a second uplink resource and / or a second downlink resource, the second downlink resource is used to send a second downlink signal to the A-IOT device, and the second uplink resource is used to receive a second uplink signal sent by the A-IOT device.

[0100] In some embodiments, the second downlink signal may be an energy source (ES) signal, and the ES signal is used to charge the A-IOT device.

[0101] In some embodiments, the second downlink signal may be a downlink transmission (DT) signal, where the DT signal includes indication information, and the indication information is used to trigger uplink transmission of the A-IOT device.

[0102] In some embodiments, the second downlink signal may be a continuous wave (CW) signal, which is used to trigger the A-IOT device to perform uplink transmission via backscatter. In particular, the CW signal may also serve as an energy source to charge the A-IOT device.

[0103] In some embodiments, the second uplink signal may be an uplink signal (Uplink transmission, UR) sent by the A-IOT device based on backscattering.

[0104] In some embodiments, the second uplink signal may be an uplink signal UR actively sent by the A-IOT device.

[0105] 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.

[0106] It should be understood that the terminal sending ES / DT / CW may be the same terminal or different terminals, and this disclosure does not limit this.

[0107] In some embodiments, the overlap of the first resource and the second resource may include: at least one of the following: the first uplink resource overlaps with the second downlink resource; the first uplink resource overlaps with the second uplink resource; the first downlink resource overlaps with the second downlink resource; the first downlink resource overlaps with the second uplink resource.

[0108] Example 1:

[0109] If the first uplink resource of the terminal overlaps with the second downlink resource, the terminal may perform at least one of the following first operations:

[0110] Sending a first uplink signal on a first symbol, canceling sending a second downlink signal on a portion where the first symbol and the second symbol overlap, where the first uplink resource includes the first symbol, the second downlink resource includes the second symbol, the first time slot is a time slot where the first uplink resource and the second downlink resource overlap, and the first symbol and the second symbol overlap in the first time slot;

[0111] Sending a second downlink signal in the first time slot and canceling sending the first uplink signal in the first time slot;

[0112] Sending a first uplink signal in a first time slot, and canceling sending a second downlink signal in the first time slot;

[0113] Sending a second downlink signal on the second symbol, and canceling sending the first uplink signal on the portion where the first symbol and the second symbol overlap;

[0114] Sending a second downlink signal on a second symbol and sending a first uplink signal on a first symbol, wherein the first symbol and the second symbol do not overlap in a first time slot;

[0115] Determined by the terminal;

[0116] Treat as an error condition;

[0117] Sending a second downlink signal and a first uplink signal, where the first uplink resource and the second downlink resource overlap in the time domain and do not overlap in the frequency domain;

[0118] Sending the second downlink signal and the first uplink signal on frequency domain resources that do not overlap with the first uplink resource and the second downlink resource, where the first uplink resource and the second downlink resource overlap in the time domain and partially overlap in the frequency domain;

[0119] Sending the second downlink signal on a frequency domain resource where the first uplink resource overlaps with the second downlink resource, and canceling sending the first uplink signal, where the first uplink resource overlaps with the second downlink resource in the time domain and partially overlaps in the frequency domain;

[0120] On the frequency domain resources where the first uplink resource overlaps with the second downlink resource, the first uplink signal is sent and sending of the second downlink signal is canceled. The first uplink resource and the second downlink resource overlap in the time domain and partially overlap in the frequency domain.

[0121] For example, the network device configures symbol #0 to symbol #9 in the first time slot as the second symbol, which is used for the terminal to send ES, CW or DT, and configures symbol #4 to symbol #13 in the first time slot as the first symbol, which is used to send the first uplink signal. The terminal can then cancel sending ES, CW or DT on the resource overlapping part (i.e., symbol #4 to symbol #9), and use symbol #4 to symbol #9 to send the first uplink signal; the terminal can also cancel sending the first uplink signal on the resource overlapping part, and use symbol #4 to symbol #9 to send ES, CW or DT.

[0122] For example, the network device configures symbol #0 to symbol #7 in the first time slot as the second symbol, which is used for the terminal to send ES, CW or DT, and configures symbol #8 to symbol #13 in the first time slot as the first symbol, which is used to send the first uplink signal. Then the terminal can send ES, CW or DT on symbol #0 to symbol #7, and send the first uplink signal on symbol #8 to symbol #13, that is, the first uplink resource and the second downlink resource overlap at the time slot granularity. When they do not overlap at the symbol granularity, the first symbol belonging to the first uplink resource is used to send the first uplink signal, and the second symbol belonging to the second downlink resource is used to send ES, CW or DT.

[0123] For example, taking the example of a network device using time slots as resource granularity to configure resources for a terminal, when the first resource and the second resource configured by the network device for the terminal both include the first time slot, the terminal can send a first uplink signal in the first time slot and cancel sending ES, CW or DT in the first time slot; or the terminal can send ES, CW or DT in the first time slot and cancel sending the first uplink signal in the first time slot.

[0124] For example, when the first uplink resources and the second downlink resources configured by the network device for the terminal overlap, the terminal itself can decide the use of the resources of the overlapping part, for example: the terminal decides to use all the resources of the overlapping part to send the first uplink signal, and cancels sending ES, CW or DT on the resources of the overlapping part; for example: the terminal decides to deactivate the resources of the overlapping part, that is, cancels sending ES, CW or DT on the resources of the overlapping part, and also cancels sending the first uplink signal on the resources of the overlapping part.

[0125] For example, when the first uplink resource and the second downlink resource configured by the network device for the terminal overlap, the terminal can handle this resource overlap as an error situation. For example, the terminal sends error feedback information to the network device to report to the network device that the first uplink resource and the second downlink resource of the terminal overlap, thereby requesting the network device to reallocate all resources of the terminal; for another example, the terminal sends error feedback information to the network device to report to the network device that the first uplink resource and the second downlink resource of the terminal overlap, thereby requesting the network device to reallocate the overlapping resources of the terminal. The present disclosure does not limit the method for handling error situations.

[0126] For example, when the first resource and the second resource configured by the network device for the terminal both include the first time slot, but the working frequency used by the terminal to send ES, CW or DT in the first time slot is different from the working frequency used to send the first uplink signal in the first time slot, for example, in the first time slot, the network device configures the terminal to send ES, CW or DT on frequency #1, frequency #2 and frequency #3, and to send the first uplink signal on frequency #4. At this time, the terminal can send the above signals respectively on the corresponding working frequencies to send the first uplink signal while sending ES, CW or DT.

[0127] For example, when the first resource and the second resource configured by the network device for the terminal both include a first time slot, and the working frequency used by the terminal to send ES, CW or DT in the first time slot is the same as the working frequency part used to send the first uplink signal in the first time slot, the terminal can send ES, CW, DT and the first uplink signal respectively on the frequencies of different parts of the working frequency, and at the same time, the terminal can send ES, CW or DT on the working frequency of the same part of the working frequency and cancel sending the first uplink signal on the working frequency of the same part, or the terminal can send the first uplink signal on the working frequency of the same part and cancel sending ES, CW or DT on the working frequency of the same part.

[0128] For example, in the first time slot, the network device configures the terminal to send ES, CW or DT on frequency #1, frequency #2 and frequency #3, and to send the first uplink signal on frequency #3 and frequency #4. At this time, the terminal can send ES, CW or DT on frequency #1, frequency #2 and frequency #3, and send the first uplink signal on frequency #4; or the terminal can send ES, CW or DT on frequency #1 and frequency #2, and send the first uplink signal on frequency #3 and frequency #4.

[0129] Example 2:

[0130] If the first downlink resource of the terminal overlaps with the second downlink resource, the terminal may perform at least one of the following first operations:

[0131] receiving a first downlink signal on a first symbol, canceling sending of a second downlink signal on a portion where the first symbol and a second symbol overlap, where the first downlink resource includes the first symbol, the second downlink resource includes the second symbol, the first time slot is a time slot where the first downlink resource and the second downlink resource overlap, and the first symbol and the second symbol overlap in the first time slot;

[0132] Sending a second downlink signal in the first time slot and canceling receiving the first downlink signal in the first time slot;

[0133] receiving a first downlink signal in a first time slot, and canceling sending a second downlink signal in the first time slot;

[0134] Sending a second downlink signal on a second symbol, and canceling receiving the first downlink signal on a portion where the first symbol and the second symbol overlap;

[0135] Sending a second downlink signal on a second symbol, receiving a first downlink signal on a first symbol, wherein the first symbol and the second symbol do not overlap in a first time slot;

[0136] Determined by the terminal;

[0137] Treat as an error condition;

[0138] Sending a second downlink signal and receiving a first downlink signal, the first downlink resource and the second downlink resource overlapping in the time domain and not overlapping in the frequency domain;

[0139] Sending a second downlink signal and receiving a first downlink signal on a frequency domain resource in which the first downlink resource and the second downlink resource do not overlap, the first downlink resource and the second downlink resource overlapping in the time domain and partially overlapping in the frequency domain;

[0140] Sending the second downlink signal on a frequency domain resource where the first downlink resource overlaps with the second downlink resource, and canceling reception of the first downlink signal, where the first downlink resource overlaps with the second downlink resource in the time domain and partially overlaps in the frequency domain;

[0141] On the frequency domain resources where the first downlink resource overlaps with the second downlink resource, the first downlink signal is received and sending of the second downlink signal is canceled. The first downlink resource overlaps with the second downlink resource in the time domain and partially overlaps in the frequency domain.

[0142] For example, the network device configures symbol #0 to symbol #9 in the first time slot as the second symbol, which is used for the terminal to send ES, CW or DT, and configures symbol #4 to symbol #13 in the first time slot as the first symbol, which is used to receive the first downlink signal. The terminal can then cancel sending ES, CW or DT on the resource overlapping part (i.e., symbol #4 to symbol #9), and use symbol #4 to symbol #9 to receive the first downlink signal; the terminal can also cancel receiving the first downlink signal on the resource overlapping part, and use symbol #4 to symbol #9 to send ES, CW or DT.

[0143] For example, the network device configures symbol #0 to symbol #7 in the first time slot as the second symbol for the terminal to send ES, CW or DT, and configures symbol #8 to symbol #13 in the first time slot as the first symbol for receiving the first downlink signal. The terminal can then send ES, CW or DT on symbol #0 to symbol #7, and receive the first downlink signal on symbol #8 to symbol #13. That is, the first downlink resource and the second downlink resource overlap at the time slot granularity. When they do not overlap at the symbol granularity, the first symbol belonging to the first downlink resource is used to receive the first downlink signal, and the second symbol belonging to the second downlink resource is used to send ES, CW or DT.

[0144] For example, taking the example of a network device using time slots as resource granularity to configure resources for a terminal, when the first downlink resource and the second downlink resource configured by the network device for the terminal both include the first time slot, the terminal can receive the first downlink signal in the first time slot and cancel sending ES, CW or DT in the first time slot; or the terminal can send ES, CW or DT in the first time slot and cancel receiving the first downlink signal in the first time slot.

[0145] For example, when the first downlink resources and the second downlink resources configured by the network device for the terminal overlap, the terminal itself can decide the use of the resources of the overlapping part, for example: the terminal decides to use all the resources of the overlapping part for receiving the first downlink signal, and cancels sending ES, CW or DT on the resources of the overlapping part; for example: the terminal decides to deactivate the resources of the overlapping part, that is, cancels sending ES, CW or DT on the resources of the overlapping part, and also cancels receiving the first downlink signal on the resources of the overlapping part.

[0146] For example, when the first downlink resource configured by the network device for the terminal overlaps with the second downlink resource, the terminal can handle this resource overlap as an error situation. For example, the terminal sends error feedback information to the network device to report to the network device that the first downlink resource of the terminal overlaps with the second downlink resource, thereby requesting the network device to reallocate all resources of the terminal; for another example, the terminal sends error feedback information to the network device to report to the network device that the first downlink resource of the terminal overlaps with the second downlink resource, thereby requesting the network device to reallocate the overlapping resources of the terminal. The present disclosure does not limit the method for handling error situations.

[0147] For example, when the first resource and the second resource configured by the network device for the terminal both include the first time slot, but the working frequency used by the terminal to send ES, CW or DT in the first time slot is different from the working frequency used to receive the first downlink signal in the first time slot, for example, in the first time slot, the network device configures the terminal to send ES, CW or DT on frequency #1, frequency #2 and frequency #3, and to receive the first downlink signal on frequency #4, so as to receive the first downlink signal while sending ES, CW or DT.

[0148] For example, when the first resource and the second resource configured by the network device for the terminal both include a first time slot, and the working frequency used by the terminal to send ES, CW or DT in the first time slot is the same as the working frequency part used to receive the first downlink signal in the first time slot, the terminal can send ES, CW, DT and the first downlink signal respectively on the frequencies of different parts of the working frequency, and at the same time, the terminal can send ES, CW or DT on the working frequency of the same part of the working frequency and cancel receiving the first downlink signal on the working frequency of the same part, or the terminal can receive the first downlink signal on the working frequency of the same part and cancel sending ES, CW or DT on the working frequency of the same part.

[0149] For example, in the first time slot, the network device configures the terminal to send ES, CW or DT on frequency #1, frequency #2 and frequency #3, and receive the first downlink signal on frequency #3 and frequency #4. At this time, the terminal can send ES, CW or DT on frequency #1, frequency #2 and frequency #3, and receive the first downlink signal on frequency #4; or the terminal can send ES, CW or DT on frequency #1 and frequency #2, and receive the first downlink signal on frequency #3 and frequency #4.

[0150] Example 3:

[0151] If the first uplink resource and the second uplink resource of the terminal overlap, the terminal may perform at least one of the following first operations:

[0152] Sending a first uplink signal on a first symbol, canceling reception of a second uplink signal on a portion where the first symbol and a second symbol overlap, where the first uplink resource includes the first symbol, the second uplink resource includes the second symbol, the first time slot is a time slot where the first uplink resource and the second uplink resource overlap, and the first symbol and the second symbol overlap in the first time slot;

[0153] receiving a second uplink signal in the first time slot and canceling sending the first uplink signal in the first time slot;

[0154] Sending a first uplink signal in a first time slot, and canceling receiving a second uplink signal in the first time slot;

[0155] receiving a second uplink signal on a second symbol, and canceling sending the first uplink signal on a portion where the first symbol and the second symbol overlap;

[0156] receiving a second uplink signal on a second symbol and sending a first uplink signal on a first symbol, wherein the first symbol and the second symbol do not overlap in a first time slot;

[0157] Determined by the terminal;

[0158] Treat as an error condition;

[0159] receiving a second uplink signal and sending a first uplink signal, wherein the first uplink resource and the second uplink resource overlap in the time domain and do not overlap in the frequency domain;

[0160] receiving the second uplink signal and sending the first uplink signal on a frequency domain resource on which the first uplink resource and the second uplink resource do not overlap, the first uplink resource and the second uplink resource overlapping in the time domain and partially overlapping in the frequency domain;

[0161] receiving the second uplink signal and canceling sending the first uplink signal on a frequency domain resource where the first uplink resource overlaps with the second uplink resource, where the first uplink resource overlaps with the second uplink resource in the time domain and partially overlaps in the frequency domain;

[0162] On the frequency domain resources where the first uplink resource overlaps with the second uplink resource, the first uplink signal is sent and reception of the second uplink signal is canceled. The first uplink resource overlaps with the second uplink resource in the time domain and partially overlaps in the frequency domain.

[0163] For example, the network device configures symbol #0-symbol #9 in the first time slot as the second symbol for the terminal to receive UR, and configures symbol #4-symbol #13 in the first time slot as the first symbol for sending the first uplink signal. The terminal can then cancel receiving UR on the resource overlapping part (i.e., symbol #4-symbol #9) and use symbol #4-symbol #9 to send the first uplink signal; the terminal can also cancel sending the first uplink signal on the resource overlapping part and use symbol #4-symbol #9 to receive UR.

[0164] For example, the network device configures symbol #0-symbol #7 in the first time slot as the second symbol for the terminal to receive UR, and configures symbol #8-symbol #13 in the first time slot as the first symbol for sending the first uplink signal. The terminal can then receive UR ​​on symbol #0-symbol #7 and send the first uplink signal on symbol #8-symbol #13, that is, the first uplink resource and the second uplink resource overlap at the time slot granularity. When they do not overlap at the symbol granularity, the first symbol belonging to the first uplink resource is used to send the first uplink signal, and the second symbol belonging to the second uplink resource is used to receive UR.

[0165] For example, taking the example of a network device using time slots as resource granularity to configure resources for the terminal, when the first uplink resource and the second uplink resource configured by the network device for the terminal both include the first time slot, the terminal can send the first uplink signal on the first time slot and cancel receiving the UR on the first time slot; or the terminal can receive the UR on the first time slot and cancel sending the first uplink signal on the first time slot.

[0166] For example, when the first uplink resources and the second uplink resources configured by the network device for the terminal overlap, the terminal itself can decide the use of the resources of the overlapping part, for example: the terminal decides to use all the resources of the overlapping part to send the first uplink signal, and cancels receiving UR on the resources of the overlapping part; for example: the terminal decides to deactivate the resources of the overlapping part, that is, cancels receiving UR on the resources of the overlapping part, and also cancels sending the first uplink signal on the resources of the overlapping part.

[0167] For example, when the first uplink resource configured by the network device for the terminal overlaps with the second uplink resource, the terminal can handle this resource overlap as an error situation. For example, the terminal sends error feedback information to the network device to report to the network device that the first uplink resource of the terminal overlaps with the second uplink resource, thereby requesting the network device to reallocate all resources of the terminal; for another example, the terminal sends error feedback information to the network device to report to the network device that the first uplink resource of the terminal overlaps with the second uplink resource, thereby requesting the network device to reallocate the overlapping resources of the terminal. The present disclosure does not limit the method for handling error situations.

[0168] For example, when the first resource and the second resource configured by the network device for the terminal both include the first time slot, but the working frequency used by the terminal to receive UR ​​in the first time slot is different from the working frequency used to send the first uplink signal in the first time slot, for example, in the first time slot, the network device configures the terminal to receive UR ​​on frequency #1 and frequency #2, and to send the first uplink signal on frequency #3, so as to send the first uplink signal while receiving UR.

[0169] For example, when the first resource and the second resource configured by the network device for the terminal both include a first time slot, and the working frequency used by the terminal to receive UR ​​in the first time slot is partially the same as the working frequency used to send the first uplink signal in the first time slot, the terminal can respectively receive UR ​​and send the first uplink signal on frequencies in different parts of the working frequency, and at the same time, the terminal can receive UR ​​on the working frequency in the same part of the working frequency and cancel sending the first uplink signal on the working frequency in the same part, or the terminal can send the first uplink signal on the working frequency in the same part and cancel receiving UR on the working frequency in the same part.

[0170] For example, in the first time slot, the network device configures the terminal to receive UR ​​on frequency #1 and frequency #2, and to send the first uplink signal on frequency #2 and frequency #3. At this time, the terminal can receive UR ​​on frequency #1 and frequency #2, and send the first uplink signal on frequency #3; or the terminal can receive UR ​​on frequency #1, and send the first uplink signal on frequency #2 and frequency #3.

[0171] Example 4:

[0172] If the first downlink resource of the terminal overlaps with the second uplink resource, the terminal may perform at least one of the following first operations:

[0173] receiving a first downlink signal on a first symbol, and canceling reception of a second uplink signal on a portion where the first symbol and the second symbol overlap, where the first downlink resource includes the first symbol, the second uplink resource includes the second symbol, the first time slot is a time slot where the first downlink resource and the second uplink resource overlap, and the first symbol and the second symbol overlap in the first time slot;

[0174] receiving a second uplink signal in the first time slot and canceling reception of the first downlink signal in the first time slot;

[0175] receiving a first downlink signal in a first time slot, and canceling receiving a second uplink signal in the first time slot;

[0176] receiving a second uplink signal on a second symbol, and canceling reception of the first downlink signal on a portion where the first symbol and the second symbol overlap;

[0177] receiving a second uplink signal on a second symbol and receiving a first downlink signal on a first symbol, wherein the first symbol and the second symbol do not overlap in a first time slot;

[0178] Determined by the terminal;

[0179] Treat as an error condition;

[0180] receiving a second uplink signal and a first downlink signal, wherein the first downlink resource and the second uplink resource overlap in the time domain and do not overlap in the frequency domain;

[0181] receiving the second uplink signal and the first downlink signal on a frequency domain resource in which the first downlink resource and the second uplink resource do not overlap, wherein the first downlink resource and the second uplink resource overlap in the time domain and partially overlap in the frequency domain;

[0182] receiving the second uplink signal and canceling reception of the first downlink signal on a frequency domain resource where the first downlink resource overlaps with the second uplink resource, where the first downlink resource overlaps with the second uplink resource in the time domain and partially overlaps in the frequency domain;

[0183] On the frequency domain resources where the first downlink resource overlaps with the second uplink resource, the first downlink signal is received and reception of the second uplink signal is canceled. The first downlink resource and the second uplink resource overlap in the time domain and partially overlap in the frequency domain.

[0184] For example, the network device configures symbol #0-symbol #9 in the first time slot as the second symbol for the terminal to receive UR, and configures symbol #4-symbol #13 in the first time slot as the first symbol for receiving the first downlink signal. The terminal can then cancel receiving UR on the resource overlapping part (i.e., symbol #4-symbol #9) and use symbol #4-symbol #9 to receive the first downlink signal; the terminal can also cancel receiving the first downlink signal on the resource overlapping part and use symbol #4-symbol #9 to receive UR.

[0185] For example, the network device configures symbol #0 to symbol #7 in the first time slot as the second symbol for the terminal to receive UR, and configures symbol #8 to symbol #13 in the first time slot as the first symbol for receiving the first downlink signal. The terminal can then receive UR ​​on symbol #0 to symbol #7 and receive the first downlink signal on symbol #8 to symbol #13, that is, the first downlink resource and the second uplink resource overlap at the time slot granularity. When they do not overlap at the symbol granularity, the first symbol belonging to the first downlink resource is used to receive the first downlink signal, and the second symbol belonging to the second uplink resource is used to receive UR.

[0186] For example, taking the example of a network device using time slots as resource granularity to configure resources for a terminal, when the first downlink resource and the second uplink resource configured by the network device for the terminal both include the first time slot, the terminal can receive the first downlink signal in the first time slot and cancel receiving the UR in the first time slot; or the terminal can receive the UR in the first time slot and cancel receiving the first downlink signal in the first time slot.

[0187] For example, when the first downlink resources and the second uplink resources configured by the network device for the terminal overlap, the terminal itself can decide the use of the resources of the overlapping part, for example: the terminal decides to use all the resources of the overlapping part to receive the first downlink signal, and cancels receiving UR on the resources of the overlapping part; for example: the terminal decides to deactivate the resources of the overlapping part, that is, cancels receiving UR on the resources of the overlapping part, and also cancels receiving the first downlink signal on the resources of the overlapping part.

[0188] For example, when the first downlink resource configured by the network device for the terminal overlaps with the second uplink resource, the terminal can handle this resource overlap as an error situation. For example, the terminal sends error feedback information to the network device to report to the network device that the first downlink resource of the terminal overlaps with the second uplink resource, thereby requesting the network device to reallocate all resources of the terminal; for another example, the terminal sends error feedback information to the network device to report to the network device that the first downlink resource of the terminal overlaps with the second uplink resource, thereby requesting the network device to reallocate the overlapping resources of the terminal. The present disclosure does not limit the method for handling error situations.

[0189] For example, when the first resource and the second resource configured by the network device for the terminal both include the first time slot, but the working frequency used by the terminal to receive UR ​​in the first time slot is different from the working frequency used to receive the first downlink signal in the first time slot, for example, in the first time slot, the network device configures the terminal to receive UR ​​on frequency #1 and frequency #2, and to receive the first downlink signal on frequency #3. At this time, the terminal can receive the above signals respectively on the corresponding working frequencies to receive the first downlink signal while receiving UR.

[0190] For example, when the first resource and the second resource configured by the network device for the terminal both include a first time slot, and the working frequency used by the terminal to receive UR ​​in the first time slot is partially the same as the working frequency used to receive the first downlink signal in the first time slot, the terminal can receive UR ​​and the first downlink signal respectively at frequencies in different parts of the working frequency, and at the same time, the terminal can receive UR ​​at the working frequency in the same part of the working frequency and cancel receiving the first downlink signal at the working frequency in the same part, or the terminal can receive the first downlink signal at the working frequency in the same part and cancel receiving UR at the working frequency in the same part.

[0191] For example, in the first time slot, the network device configures the terminal to receive UR ​​on frequency #1 and frequency #2, and to receive the first downlink signal on frequency #2 and frequency #3. At this time, the terminal can receive UR ​​on frequency #1 and frequency #2, and receive the first downlink signal on frequency #3; or the terminal can receive UR ​​on frequency #1, and receive the first downlink signal on frequency #2 and frequency #3.

[0192] In particular, in some embodiments, when a terminal is capable of both sending a CW and receiving a UR, the terminal performs the same first operation when sending a CW and receiving a UR when the first resource and the second resource configured for the terminal by the network device overlap. For example, when the first uplink resource and the second downlink resource of the terminal overlap in the first time slot, the terminal chooses to send a CW in the first time slot and cancels sending the first uplink signal in the first time slot. Then, when the first uplink resource and the second uplink resource of the terminal overlap in the second time slot, the terminal may choose to receive the UR in the second time slot and cancel sending the first uplink signal in the second time slot.

[0193] Optionally, with respect to several examples of the above-mentioned embodiments 1 to 4, in some embodiments, resources may be grouped according to their configuration type or resource usage. For example, performing the first operation includes: when the terminal uses a first uplink resource belonging to the first group to send a first uplink signal, performing the same first operation; when the terminal uses a first downlink resource belonging to the first group to receive a first downlink signal, performing the same first operation; when the terminal uses a second uplink resource belonging to the first group to receive a second uplink signal, performing the same first operation; and when the terminal uses a second downlink resource belonging to the first group to send a second downlink signal, performing the same first operation.

[0194] 1) Group by resource configuration type:

[0195] In some embodiments, the first group can be a semi-statically configured first uplink resource; a dynamically configured first uplink resource; a semi-statically configured first downlink resource; a dynamically configured first downlink resource; a semi-statically configured second uplink resource; a dynamically configured second uplink resource; a semi-statically configured second downlink resource; a dynamically configured second downlink resource; in other words, the dynamically configured resources can be grouped as a group, and the 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 conflict. For example, for the semi-statically configured first uplink resource, in the event of resource overlap, the "treat it as an error situation" method is adopted.

[0196] 2) Group by resource usage:

[0197] In some embodiments, the first group may include a second downlink resource for transmitting an ES signal; a second downlink resource for transmitting a DT signal; a second downlink resource for transmitting a CW signal; and a second uplink resource for receiving an UR signal. In other words, resources for transmitting an ES signal, a second downlink resource for transmitting a DT signal, a second downlink resource for transmitting a CW signal, and a second uplink resource for receiving an UR signal may be grouped together. Resources in the same group may be handled in the same manner in the event of resource overlap. For example, for the first resource used to transmit an ES signal, in the event of a resource conflict, the "terminal-determined" approach may be adopted.

[0198] Step 2102: The terminal sends a second downlink signal to the A-IOT device.

[0199] In some embodiments, the terminal sends a second downlink signal to the A-IOT device to enable communication between the terminal and the A-IOT device.

[0200] In some embodiments, step 2102 is optional and is included in step 2101. For example, taking the example of a network device using time slots as resource granularity to configure resources for a terminal, when the first downlink resource and the second downlink resource configured by the network device for the terminal both include the first time slot, the terminal can send ES, CW or DT on the first time slot and cancel receiving the first downlink signal on the first time slot, so as to enable the terminal to send the second downlink signal to the A-IOT device.

[0201] Step 2103: The A-IOT device sends a second uplink signal to the terminal.

[0202] In some embodiments, the A-IOT device sends a second uplink signal to the terminal 101 to enable communication between the terminal and the A-IOT device.

[0203] In some embodiments, step 2103 is optional and is included in step 2101. For example, taking the example of a network device using time slots as resource granularity to configure resources for a terminal, when the first uplink resource and the second uplink resource configured by the network device for the terminal both include the first time slot, the terminal can receive the UR sent by the A-IOT device in the first time slot and cancel sending the first uplink signal in the first time slot, so as to enable the terminal to send the second downlink signal to the A-IOT device.

[0204] 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.

[0205] 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.

[0206] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2103. For example, step 2101 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, steps 2101+2102 may be implemented as independent embodiments, and steps 2101+2102+2103 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0256] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, A-IOT device side, etc., which will not be repeated here.

[0257] The following is an exemplary introduction to the disclosed solution.

[0258] In order to support data transmission of A-IOT devices, the network needs to support the following functions. A device in the network can support one or more functions.

[0259] (1) As an excitation (Continuous Wave, CW) function, it is only used for Devices A and B. A-IOT device achieves uplink transmission by backscattering CW.

[0260] (2) As an Energy Source (ES), it can be used for device types B and C. CW is actually a type of ES, and A-IOT devices can receive CW and store energy. For device type A, because the supported 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.

[0261] (3) Downlink transmission (DT) function, which sends indication information to the A-IOT device, thereby triggering the uplink transmission of the A-IOT device.

[0262] (4) Uplink receiving (UR) function, which receives the uplink information backscattered by the A-IOT device, or receives the uplink information actively transmitted by the A-IOT device.

[0263] In addition to implementing one or more of the above functions, the device in the network can also perform uplink and downlink (i.e., the above-mentioned first uplink signal and the first downlink signal) transmission of the cellular network. For the one device, the network needs to coordinate the resource allocation of the above functions and uplink and downlink transmission of the cellular network. 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, a channel or signal can support both ES and CW functions, so that only resource configuration needs to be performed on one channel or signal.

[0264] Example 1:

[0265] The ES signal of the UE can be semi-statically configured or dynamically indicated. Similarly, other uplink and downlink channels / signals of cellular communication (ie, the first uplink signal and the first downlink signal) can be semi-statically configured or dynamically indicated.

[0266] Example 1:

[0267] Generally, if the ES signal overlaps with an uplink channel / signal of cellular communication (e.g., PUSCH, PUCCH, SRS, PRACH), the UE may perform one of the following methods:

[0268] 1. The UE does not transmit ES signals in the overlapping portion and can transmit uplink channels / signals. As long as the uplink channel / signal of cellular communication transmitted by the UE falls within the bandwidth range of the A-IoT device and the received power level reaching the A-IoT device exceeds a certain threshold, it can still charge the A-IoT device.

[0269] 2. The UE transmits ES signals but does not transmit uplink channels / signals.

[0270] 3. The UE transmits the ES signal and does not transmit the uplink channel / signal of the cellular communication that overlaps with the ES signal. For example, this method can be used when the uplink transmission is PUSCH or SRS.

[0271] 4. The UE decides whether to transmit the ES signal or the uplink channel / signal of the cellular communication. For example, this method can be used when the PRACH or MsgAPUSCH is configured for uplink transmission.

[0272] 5. The situation where the ES signal overlaps with the uplink channel / signal of cellular communication is an error configuration (ErrorCase). For example, this method can be used when both the ES signal and the uplink channel / signal are dynamically scheduled.

[0273] 6. The ES signal overlaps with the uplink channel / signal of cellular communication in time, but not in frequency. The UE can transmit the ES signal and the uplink channel / signal simultaneously. This behavior can also be defined as a UE capability.

[0274] 7. If the ES signal overlaps with the uplink channel / signal of cellular communication in both time and frequency, the UE transmits the ES signal and the uplink channel / signal of cellular communication on non-overlapping time-frequency resources, respectively, and may transmit only one of the ES signal and the uplink channel / signal on resources with overlapping time-frequency. The signal transmitted by the UE on the time-frequency overlapping resources may be predefined or configured. This behavior may also be defined as a UE capability.

[0275] 8. When the ES signal overlaps with the uplink channel / signal of cellular communication, it is possible to not distinguish the uplink channel / signal of cellular communication, distinguish the semi-statically configured ES signal and the dynamically indicated ES signal, and adopt any one of the above methods 1-6 respectively.

[0276] Alternatively, ES signals may not be differentiated, but semi-statically configured uplink channels / signals and dynamically indicated uplink channels / signals of cellular communications may be differentiated, and any one of the above methods 1-6 may be adopted respectively.

[0277] Alternatively, either ES signals or uplink channels / signals of cellular communications may be undifferentiated, and any one of the above methods 1-6 may be uniformly adopted.

[0278] 9. It is possible to distinguish between semi-statically configured ES signals and dynamically indicated ES signals, and further group uplink channels / signals of cellular communications, using any of the above methods 1-6 to process one ES signal and one group of uplink channels / signals, respectively. For example, the configured PRACH and MsgA PUSCH are the first group, the semi-statically configured PUSCH, PUCCH, and SRS are the second group, and the dynamically scheduled PUSCH, PUCCH, SRS, and PRACH are the third group.

[0279] 10. It may be possible to distinguish between semi-statically configured ES signals and dynamically indicated ES signals, and further distinguish between uplink channels / signals of each type of cellular communication, and use any one of the above methods 1-6 to process an ES signal and an uplink channel / signal of a cellular communication, respectively.

[0280] Example 2:

[0281] Generally, if the ES signal overlaps with the downlink channel / signal of cellular communication, or there is insufficient uplink / downlink switching time, for example, PDCCH, PDSCH, CSI-RS, DL PRS, the UE may perform one of the following methods:

[0282] 1. The UE does not transmit ES signals during overlapped or insufficient uplink / downlink transition time, and can receive cellular communication downlink channels / signals. As long as the cellular communication downlink channels / signals sent to the UE fall within the bandwidth of the A-IoT device and the received power level reaching the A-IoT device exceeds a certain threshold, the A-IoT device can still be charged.

[0283] 2. The UE transmits ES signals and does not receive downlink channels / signals of cellular communications.

[0284] 3. The UE transmits the ES signal and does not receive the downlink channel / signal of the cellular communication that overlaps with the ES signal or does not have sufficient uplink / downlink switching time.

[0285] 4. The UE decides whether to transmit ES signals or receive downlink channels / signals of cellular communications.

[0286] 5. The situation where the ES signal overlaps with the downlink channel / signal of cellular communication is an error configuration (ErrorCase). For example, this method can be used when both the ES signal and the downlink channel / signal are dynamically scheduled.

[0287] 6. The UE's behavior in processing the ES signal is the same as its behavior in processing a cellular communication downlink channel / signal. For example, the cellular communication downlink channel / signal may be a reference downlink channel / signal SRS. The selection of the reference downlink channel / signal may be related to whether the ES signal is semi-statically configured or dynamically indicated.

[0288] 7. ES signals overlap in time with cellular communication downlink channels / signals, but do not overlap in frequency. The UE may simultaneously transmit ES signals and receive cellular communication downlink channels / signals. This simultaneous transmission may be performed only when the ES signals and the cellular communication downlink channels / signals are separated by a large frequency. This behavior may also be defined as a UE capability.

[0289] 8. ES signals overlap with downlink channels / signals of cellular communications in both time and frequency. The UE transmits ES signals and receives downlink channels / signals of cellular communications on non-overlapping time-frequency resources, respectively. On resources with overlapping time-frequency resources, the UE may transmit only ES signals or receive only downlink channels / signals of cellular communications. The UE's behavior on resources with overlapping time-frequency resources may be predefined or configurable. This behavior may also be defined as a UE capability.

[0290] 9. ES signals overlap with downlink channels / signals of cellular communications in both time and frequency. The UE can transmit ES signals and receive downlink channels / signals of cellular communications separately. This behavior can also be defined as a UE capability.

[0291] 10. When the ES signal overlaps with the downlink channel / signal of cellular communication, or there is insufficient time for uplink / downlink conversion, it is possible to not distinguish between the downlink channel / signal of cellular communication, distinguish between the semi-statically configured ES signal and the dynamically indicated ES signal, and adopt any one of the above methods 1-6 respectively.

[0292] Alternatively, ES signals may not be distinguished, but downlink channels / signals of semi-statically configured cellular communications and downlink channels / signals of dynamically indicated cellular communications may be distinguished, and any one of the above methods 1-6 may be used respectively.

[0293] Alternatively, any one of the above methods 1-6 may be uniformly adopted without distinguishing between ES signals and downlink channels / signals of cellular communications.

[0294] 11. It is possible to distinguish between semi-statically configured ES signals and dynamically indicated ES signals, and further group downlink channels / signals of cellular communications, using any of the above methods 1-6 to process one ES signal and one group of downlink channels / signals of cellular communications, respectively. For example, SSB is a first group, semi-statically configured PDCCH, PDSCH, CSI-RS, and DL PRS are a second group, and dynamically scheduled CSI-RS and PDSCH are a third group.

[0295] 12. It may be possible to distinguish between semi-statically configured ES signals and dynamically indicated ES signals, and further distinguish between downlink channels / signals of each type of cellular communication, and use any one of the above methods 1-6 to process an ES signal and a downlink channel / signal of cellular communication, respectively.

[0296] Example 2:

[0297] The CW of the UE may be semi-statically configured or dynamically indicated. Similarly, other uplink and downlink channels / signals of the cellular communication (ie, the first uplink signal and the first downlink signal) may be semi-statically configured or dynamically indicated.

[0298] Example 1:

[0299] Generally, if the CW overlaps with an uplink channel / signal (e.g., PUSCH, PUCCH, SRS, PRACH), the UE may perform one of the following methods:

[0300] 1. The UE transmits CW signals instead of cellular uplink channels / signals. The UE prioritizes CW transmission, allowing the A-IoT device to perform normal uplink transmission based on backscatter without affecting the receiving end's ability to receive uplink information from the A-IoT device.

[0301] 2. The UE transmits CWs and does not transmit any cellular communication uplink channels / signals that overlap with the CWs. For example, this method can be used when the uplink transmission is PUSCH or SRS. The UE prioritizes CW transmission, allowing the A-IoT device to perform normal uplink transmission based on backscatter without affecting the receiving end's ability to receive uplink information from the A-IoT device.

[0302] 3. The UE does not transmit CW in the overlapping portion and may transmit uplink channels / signals of cellular communication.

[0303] 4. The UE decides whether to transmit CW or cellular communication uplink channels / signals. For example, this method can be used when PRACH or MsgA PUSCH is configured for uplink transmission.

[0304] 5. Overlapping of CW signals with cellular communication uplink channels / signals is an error case. For example, this method can be used when both CW and uplink channels / signals are dynamically scheduled.

[0305] 6. The UE's behavior in processing CW is the same as that in processing UR.

[0306] 7. When the CW overlaps with the uplink channel / signal of cellular communication, it is possible to not distinguish the uplink channel / signal of cellular communication, but distinguish between the semi-statically configured CW and the dynamically indicated CW, and adopt any of the above methods 1-6 respectively.

[0307] Alternatively, the CW may not be differentiated, but the uplink channel / signal of the semi-statically configured cellular communication and the uplink channel / signal of the dynamically indicated cellular communication may be differentiated, and any one of the above methods 1-6 may be adopted respectively.

[0308] Alternatively, neither CW nor uplink channels / signals of cellular communications may be distinguished, and any one of the above methods 1-6 may be uniformly adopted.

[0309] 8. It is possible to distinguish between semi-statically configured CWs and dynamically indicated CWs, and further group the cellular communication uplink channels / signals. Any of the above methods 1-6 can be used to process one CW and one group of cellular communication uplink channels / signals, respectively. For example, the configured PRACH and MsgA PUSCH are in the first group, the semi-statically configured PUSCH, PUCCH, and SRS are in the second group, and the dynamically scheduled PUSCH, PUCCH, SRS, and PRACH are in the third group.

[0310] 9. It is possible to distinguish between semi-statically configured CWs and dynamically indicated CWs, and further distinguish between each type of cellular communication uplink channel / signal, and respectively use any one of the above methods 1-6 to process a type of CW and an uplink channel / signal.

[0311] 10. The UE's behavior in processing the CW is the same as its behavior in processing a cellular communication uplink channel / signal. For example, the cellular communication uplink channel / signal may be a reference uplink channel / signal PUSCH. The selection of the reference uplink channel / signal may be related to whether the CW is semi-statically configured or dynamically indicated.

[0312] Example 2:

[0313] Generally, if the CW overlaps with a downlink channel / signal (e.g., PDCCH, PDSCH, CSI-RS, DL PRS) of cellular communication, or there is insufficient uplink / downlink switching time, the UE may perform one of the following methods:

[0314] 1. The UE transmits CW and does not receive the downlink channel / signal of cellular communication. The UE prioritizes CW transmission, allowing the A-IoT device to perform normal uplink transmission based on backscattering without affecting the receiving end's operation of receiving uplink information from the A-IoT device.

[0315] 2. The UE transmits CW and does not receive downlink channels / signals that overlap with CW or do not have sufficient uplink / downlink transition time. The UE prioritizes CW transmission, allowing the A-IoT device to perform normal uplink transmission based on backscatter without affecting the receiving end's operation of receiving uplink information from the A-IoT device.

[0316] 3. The UE does not transmit CW in the portion where the uplink / downlink switching time overlaps or is insufficient, and can receive the downlink channel / signal of the cellular communication.

[0317] 4. The UE decides whether to transmit CW or receive the downlink channel / signal of cellular communication.

[0318] 5. Overlapping of CW signals with cellular uplink channels / signals is an error case. For example, this method can be used when both CW and cellular downlink channels / signals are dynamically scheduled.

[0319] 6. When the CW overlaps with the downlink channel / signal of cellular communication, or there is insufficient uplink / downlink switching time, the downlink channel / signal of cellular communication may be not distinguished, and the semi-statically configured CW and the dynamically indicated CW may be distinguished, and one of the above processing methods may be used for each.

[0320] Alternatively, the CW may not be differentiated, but the downlink channel / signal of the semi-statically configured cellular communication and the downlink channel / signal of the dynamically indicated cellular communication may be differentiated, and any one of the above methods 1-5 may be adopted respectively.

[0321] Alternatively, neither CW nor downlink channels / signals of cellular communications may be distinguished, and any one of the above methods 1-5 may be uniformly adopted.

[0322] 7. It is possible to distinguish between semi-statically configured CWs and dynamically indicated CWs, and further group downlink channels / signals for cellular communications, using any of the above methods 1-5 to process one CW and one group of downlink channels / signals, respectively. For example, SSBs may be a first group, semi-statically configured PDCCHs, PDSCHs, CSI-RSs, and DL PRSs may be a second group, and dynamically scheduled CSI-RSs and PDSCHs may be a third group.

[0323] 8. It is possible to distinguish between semi-statically configured CWs and dynamically indicated CWs, and further distinguish between downlink channels / signals of each type of cellular communication, and use any one of the above methods 1-5 to process a CW and a downlink channel / signal of a cellular communication respectively.

[0324] Example 3:

[0325] The UR resources of the UE receiving uplink transmissions from the A-IoT device can be semi-statically configured or dynamically indicated. Similarly, other uplink and downlink channels / signals of cellular communications can be semi-statically configured or dynamically indicated.

[0326] Example 1:

[0327] Generally, if the UR resource overlaps with an uplink channel / signal (e.g., PUSCH, PUCCH, SRS, PRACH) of cellular communication, the UE may perform one of the following methods:

[0328] 1. The UE receives uplink transmissions from A-IoT devices on UR resources and does not transmit uplink channels / signals for cellular communications. The UE prioritizes receiving uplink transmissions from A-IoT devices on UR resources, allowing the A-IoT device to continue performing backscatter-based uplink transmissions or active uplink transmissions.

[0329] 2. The UE receives uplink transmissions from the A-IoT device on the UR resources and does not transmit uplink channels / signals of cellular communications that overlap with the UR resources. The UE prioritizes receiving uplink transmissions from the A-IoT device on the UR resources, allowing the A-IoT device to continue performing backscatter-based uplink transmissions or active uplink transmissions.

[0330] 3. The UE does not receive the uplink transmission of the A-IoT device on the UR resources in the overlapping part, and can transmit the uplink channel / signal of the cellular communication.

[0331] 4. The UE implementation decides whether to receive uplink transmissions from A-IoT devices on UR resources or transmit uplink channels / signals for cellular communications. For example, this method can be used when PRACH or MsgA PUSCH is configured for uplink transmission.

[0332] 5. Overlapping of UR signals with cellular uplink channels / signals is an error case. For example, this method can be used when both UR resources and cellular uplink channels / signals are dynamically scheduled.

[0333] 6. The UE's behavior in processing the UR resource is the same as its behavior in processing a reference downlink channel / signal. For example, the reference downlink channel / signal may be an SSB. The selection of the reference downlink channel / signal may be related to whether the UR resource is semi-statically configured or dynamically indicated.

[0334] 7. When UR resources overlap with the uplink channel / signal of cellular communication, it is possible to not distinguish the uplink channel / signal of cellular communication, distinguish between semi-statically configured UR resources and dynamically indicated UR resources, and adopt one of the above processing methods respectively.

[0335] Alternatively, UR resources may not be differentiated, but uplink channels / signals of semi-statically configured cellular communications and uplink channels / signals of dynamically indicated cellular communications may be differentiated, and any one of the above methods 1-6 may be adopted for each of them.

[0336] Alternatively, no distinction may be made between UR resources and uplink channels / signals of cellular communications, and any one of the above methods 1-6 may be uniformly adopted.

[0337] 8. It is possible to distinguish between semi-statically configured UR resources and dynamically indicated UR resources, and further group the cellular communication uplink channels / signals, using any of the above methods 1-6 to process one UR resource and one group of cellular communication uplink channels / signals.

[0339] Example 2:

[0340] Generally, if the UR resource overlaps with the downlink channel / signal of cellular communication, or there is insufficient uplink / downlink switching time, for example, PDCCH, PDSCH, CSI-RS, DL PRS, the UE may perform one of the following methods:

[0341] 1. The UE receives uplink transmissions from A-IoT devices on UR resources and does not receive downlink channels / signals from cellular communications.

[0342] 2. The UE receives uplink transmissions from A-IoT devices on UR resources and does not receive downlink channels / signals from cellular communications that overlap with UR resources or do not have sufficient uplink / downlink transition time. The UE prioritizes receiving uplink transmissions from A-IoT devices on UR resources, allowing the A-IoT device to continue performing backscatter-based uplink transmissions or proactive uplink transmissions.

[0343] 3. The UE does not receive the uplink transmission of the A-IoT device on the UR resources during the overlap or insufficient uplink / downlink switching time, and can receive the downlink channel / signal of the cellular communication.

[0352] Example 4:

[0353] The DT resources used by the UE for downlink transmission to the A-IoT device can be semi-statically configured or dynamically indicated. Similarly, other uplink and downlink channels / signals in cellular communications can be semi-statically configured or dynamically indicated.

[0354] Example 1:

[0355] Generally, if the DT resources overlap with uplink channels / signals of cellular communications (e.g., PUSCH, PUCCH, SRS, PRACH), the UE may perform one of the following methods:

[0356] 1. The UE performs downlink transmissions to the A-IoT device on DT resources and does not transmit uplink channels / signals for cellular communications. The UE prioritizes downlink transmissions to the A-IoT device on DT resources so that the A-IoT device can still receive downlink information normally.

[0357] 2. The UE performs downlink transmissions to the A-IoT device on the DT resources and does not transmit uplink channels / signals of cellular communications that overlap with the DT resources. The UE prioritizes downlink transmissions to the A-IoT device on the DT resources, allowing the A-IoT device to still receive downlink information normally.

[0358] 3. The UE does not perform downlink transmission to the A-IoT device on the DT resources in the overlapping part, and can transmit the uplink channel / signal of the cellular communication.
