[0085] 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.

[0086] In the related art, A-IOT devices need to collect energy from surrounding devices in order to receive downlink information or transmit uplink information. A-IOT device types A and B transmit uplink information by backscattering the CW signals of surrounding devices. A-IOT device type C works based on active transmission. Accordingly, the downlink transmission, CW, reception of uplink signals of A-IOT devices, and charging signals sent to A-IOT devices need to be coordinated to support the normal uplink and downlink transmission of A-IOT devices. In summary, effective scheduling of normal uplink and downlink transmission of A-IOT devices is a problem that needs to be solved.

[0087] Therefore, the present disclosure proposes a communication method and device, a communication system, a communication device, and a storage medium, which supports efficient data transmission of A-IOT devices by using the same DCI to coordinate the downlink transmission, CW, reception of uplink signals to A-IOT devices, and charging signals sent to A-IOT devices.

[0088] The method proposed in the present disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance and subsequent communication technologies (such as 6G, etc.).

[0089] First, a brief introduction to the relevant terms in this application:

[0090] ES: Energy Source (ES) signal. ES functionality is available for device types B and C. CW is also a type of ES; A-IoT devices can receive CW and store energy. For device type A, because it supports significant energy storage, ES signals other than CW can be omitted, or ES signals can be used for device type A.

[0091] DT: Downlink transmission (DT) signal. The DT function is used to send indication information to the A-IOT device, thereby triggering the uplink transmission of the A-IOT device.

[0092] CW: excitation signal, generally a continuous wave (CW) signal. The excitation function of CW is only used for types A and B. A-IOT devices achieve uplink transmission through backscatter CW. In this disclosure, CW refers to the excitation signal. In this disclosure, continuous wave signal and excitation signal can be used interchangeably. In the scheme of the present disclosure, continuous wave and excitation refer to the same signal. The excitation signal can be a continuous wave, but is not limited to this. It can also be other signals used to enable A-IoT devices and A-IoT device groups to send uplink signals based on backscattering. The names of excitation and continuous wave can be interchangeable.

[0129] Figure 2 is an interactive diagram of a communication method provided by an embodiment of the present disclosure. As shown in Figure 2, the present disclosure embodiment relates to a communication method based on the environmental Internet of Things. The method can be executed by a communication system, such as the communication system 100 shown in Figure 1. The communication system includes a first device and a second device. The interactive method may include the following steps:

[0130] Step 2101: The first device sends first information to the second device.

[0131] In some embodiments, the first information is used to indicate a first time-frequency resource.

[0132] In some embodiments, the first information may be downlink control information DCI.

[0133] For example, the first device sends DCI to the second device for coordinating time-frequency resources for communication of an A-IOT device or a group of A-IOT devices.

[0134] In some embodiments, the first information may be one or more.

[0135] For example, the first device sends a DCI to a second device, where the DCI indicates the time-frequency resources for the second device to communicate with the A-IOT device or the A-IOT device group, or the first device sends a DCI to multiple second devices, where the DCI indicates the time-frequency resources for the multiple second devices to communicate with the A-IOT device or the A-IOT device group; or the first device sends multiple DCIs to a second device, where each DCI indicates the time-frequency resources of a different function, or the first device sends a DCI to multiple second devices respectively, where each DCI indicates the time-frequency resources of a different function of the corresponding second device.

[0136] In some embodiments, a cyclic redundancy check (CRC) of the first information is masked using a common radio network temporary identifier (C-RNTI) of the plurality of second devices. For example, when the plurality of second devices detect the same DCI, the CRC of the DCI may be masked using the C-RNTI common to the plurality of second devices.

[0137] In some embodiments, the first time-frequency resource is used for the second device to communicate with an ambient Internet of Things (A-IOT) device or an A-IOT device group.

[0138] In some embodiments, the second device supports at least one of ES, DT, CW, and UR functions.

[0139] In some embodiments, the first device and the second device may be the same device or different devices.

[0140] For example, the first device may be a device responsible for coordinating ES, DT, CW, and UR functions, and the second device may be a device that performs the above-mentioned ES, DT, CW, and UR functions; or, the first device may be a device responsible for coordinating ES, DT, CW, and UR functions and a device that performs the above-mentioned functions.

[0141] For example, the second device may be a device responsible for coordinating ES, DT, CW, and UR functions and a device that performs the above functions.

[0142] In some embodiments, the first time-frequency resource may be a resource for the second device to send an ES signal to an A-IOT device or an A-IOT device group.

[0143] In some embodiments, the first time-frequency resource may be a resource for the second device to send a DT signal to an A-IOT device or an A-IOT device group.

[0144] In some embodiments, the first time-frequency resource may be a resource for the second device to send a CW signal to an A-IOT device or an A-IOT device group.

[0145] In some embodiments, the first time-frequency resource may be a resource for the second device to receive a UR signal backscattered or actively sent by an A-IOT device or an A-IOT device group.

[0146] In some embodiments, the first time-frequency resource is a resource used for a second device to communicate with an A-IOT device or a group of A-IOT devices.

[0147] In some embodiments, the first time-frequency resource is a resource used for communication between multiple second devices and an A-IOT device or an A-IOT device group.

[0148] In some embodiments, the first device sending the first information to the second device may be sending one or more first information to one second device.

[0149] In some embodiments, the first device sending the first information to the second device may be sending one or more pieces of first information to multiple second devices respectively.

[0150] In some embodiments, the first time-frequency resource may be semi-statically configured.

[0151] In some embodiments, the first time-frequency resource may be dynamically scheduled via first information. For example, the first time-frequency resource may be dynamically scheduled via downlink control information (DCI).

[0152] In some embodiments, the first information may be used to instruct the second device with DT function to send a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource.

[0153] In some embodiments, the first information may be used to instruct the second device with CW function to send a CW signal to the A-IOT device or the A-IOT device group on the first time-frequency resource.

[0154] In some embodiments, the first information may be used to instruct the second device with UR function to receive the UR signal actively sent by the A-IOT device or the A-IOT device group on the first time-frequency resource.

[0155] In the above embodiment, the first information may indicate only one of the DT, CW, and UR functions, or may indicate multiple of the above functions. The first information may be sent to one second device or to multiple second devices.

[0156] In some embodiments, the first information may be sent to a second device to indicate a time-frequency resource of a function.

[0157] For example, one DCI may indicate the time-frequency resources for only one of the DT, CW, and UR functions. That is, multiple DCIs need to be sent to indicate the time-frequency resources for all functions. In other words, if a second device needs to perform all functions, the first device needs to send multiple DCIs to the second device.

[0158] In some embodiments, the first information may be sent to one or more second devices, indicating time-frequency resources for multiple functions, and the time-frequency resources for multiple functions do not distinguish which second device is used.

[0159] For example, a single DCI can indicate the time-frequency resources for multiple functions including DT, CW, and UR. This means that multiple DCIs need to be sent to indicate the time-frequency resources for all functions. In other words, if a second device needs to perform all functions, the first device may need to send multiple DCIs to a second device. A single DCI can also be sent to multiple second devices, and the time-frequency resources indicated by the DCI do not distinguish between specific second devices.

[0160] In some embodiments, the first information may be sent to a second device to indicate time-frequency resources of all functions.

[0161] For example, one DCI can indicate the time-frequency resources for all of the above-mentioned DT, CW, and UR functions. That is, only one DCI needs to be sent to indicate the time-frequency resources for all functions. In other words, if a second device needs to perform all functions, the first device only needs to send one DCI to the second device.

[0162] In some embodiments, the first information may be sent to a specific second device among multiple second devices, indicating time-frequency resources for performing two or more functions.

[0163] For example, one DCI may indicate the time-frequency resources of one of the second devices performing DT, CW, and UR functions. That is, if one second device performs two or more functions simultaneously, the two or more functions may be indicated simultaneously by one DCI. The DCI carries the identifier of the second device.

[0164] For example, a DCI may indicate the time-frequency resources of one of the second devices that perform DT, CW, and UR functions. For example, a second device may simultaneously support CW transmission and reception of backscattered UR signals, and the time-frequency resources for CW and UR may be indicated by the same DCI. In other words, the time-frequency resources of a certain function indicated by the DCI are only used for a certain second device, that is, the first information carries the information of the second device, and the time-frequency resources that match the capabilities of the second device are configured for use by the device.

[0165] In some embodiments, the first information may be sent to multiple second devices, indicating one, multiple or all time-frequency resources.

[0166] For example, a DCI can indicate the time-frequency resources of one, multiple or all of the above-mentioned DT, CW, and UR functions. The first device can send a DCI to multiple second devices, that is, multiple second devices are configured to detect the same DCI, and each second device uses the corresponding time-frequency resources according to its function.

[0167] For example, a DCI instructs a second device with a DT function to use time-frequency resource 1 to send a DT signal, instructs a second device with a CW function to use time-frequency resource 2 to send a CW signal, and instructs a second device with a UR function to use time-frequency resource 3 to receive a UR signal actively sent by an A-IOT device or an A-IOT device group.

[0168] For example, a DCI instructs a second device with a CW function to use time-frequency resource 1 to send a CW signal, and instructs a second device with a UR function to use time-frequency resource 2 to receive a UR signal backscattered by an A-IOT device or an A-IOT device group.

[0169] In some embodiments, the first information may be used to instruct a second device with a DT function to send a DT signal to an A-IOT device or an A-IOT device group on a first time-frequency resource, and a second device with a CW function and / or a UR function to send a CW signal to an A-IOT device or an A-IOT device group on a second time-frequency resource and / or receive an UR signal backscattered by the A-IOT device or the A-IOT device group.

[0170] For example, a DCI may instruct a second device with a DT function to send a DT signal on a first time-frequency resource, and instruct a second device with a CW function to send a CW signal on a second time-frequency resource.

[0171] For example, a DCI may instruct the second device with DT functionality to send a DT signal on a first time-frequency resource, and instruct the second device with UR functionality to receive a backscattered UR signal on a second time-frequency resource.

[0172] For example, one DCI may instruct a second device with DT functionality to send a DT signal on a first time-frequency resource, and instruct a second device with CW and UR functionality to send a CW signal on a second time-frequency resource and receive a backscattered UR signal.

[0173] In some embodiments, the first information may be used to instruct the second device with DT function to send a DT signal to the A-IOT device or A-IOT device group on the first time-frequency resource, and the second device with UR function to receive the UR signal actively sent by the A-IOT device or A-IOT device group on the second time-frequency resource.

[0174] For example, a DCI may instruct a second device with DT functionality to transmit a DT signal on a first time-frequency resource, and instruct a second device with UR functionality to receive an actively transmitted UR signal on a second time-frequency resource. In other words, a first message may instruct different second devices to perform corresponding data transmission.

[0175] In the above embodiment, the first device sends different first information to the one or more second devices, thereby scheduling the one or more second devices to perform data transmission with the A-IOT device or the A-IOT device group.

[0176] Step 2102: The second device communicates with the A-IOT device or the A-IOT device group using the first time-frequency resource.

[0177] In some embodiments, the second device may communicate with one A-IOT device or a group of A-IOT devices.

[0178] In some embodiments, the second device may be one or more. In other words, for one or a group of A-IOT devices, one or more second devices may perform the same function among the aforementioned DT, CW, and UR functions, or one second device may perform one or more of the aforementioned functions.

[0179] In some embodiments, a DCI indicates a time-frequency resource for performing a DT function, and the second device sends a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource, does not send an ES signal and / or a CW signal on the first time-frequency resource, and does not receive a UR signal on the first time-frequency resource. The second device has a DT function, and the first information indicates that the second device with the DT function sends a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource.

[0180] For example, a DCI instructs a device performing a DT function to perform downlink transmission to an A-IOT device on time-frequency resource A. After detecting the DCI, a device performing an ES function does not transmit an ES signal on time-frequency resource A. After detecting the DCI, a device performing a CW function does not transmit a CW signal on time-frequency resource A. After detecting the DCI, a device performing an UR function does not receive an UR signal on time-frequency resource A.

[0181] In some embodiments, a DCI indicates a time-frequency resource for performing CW and / or UR functions, and the second device sends a CW signal to the A-IOT device or the A-IOT device group on the first time-frequency resource, and / or receives the UR signal backscattered by the A-IOT device or the A-IOT device group on the first time-frequency resource, and does not send an ES signal and / or a DT signal on the first time-frequency resource, wherein the second device has a CW function and / or a UR function, and the first information indicates that the second device with the CW function and / or the UR function sends a CW signal to the A-IOT device or the A-IOT device group on the first time-frequency resource and / or receives the UR signal backscattered by the A-IOT device or the A-IOT device group.

[0182] For example, a DCI instructs a device performing a CW function to transmit a CW on time-frequency resource B and to receive the uplink signal UR backscattered by an A-IOT device type A or B on time-frequency resource B; a device with an ES function does not send an ES signal on time-frequency resource B; and a device with a DT function does not send a DT signal on time-frequency resource B.

[0183] In the above embodiment, the device that performs the CW function and the device that performs the UR function may be the same device or different devices.

[0184] In some embodiments, a DCI indicates a time-frequency resource for performing a UR function, and the second device receives the UR signal actively sent by the A-IOT device or the A-IOT device group on the first time-frequency resource, and does not send at least one of the ES signal, the DT signal, and the CW signal on the first time-frequency resource, wherein the second device has a UR function, and the first information indicates that the second device with the UR function receives the UR signal actively sent by the A-IOT device or the A-IOT device group on the first time-frequency resource.

[0185] For example, a DCI indicates that a device performing the UR function receives the uplink signal UR actively sent by the A-IOT device type C on the time-frequency resource C, a device performing the ES function does not send the ES signal on the time-frequency resource C, a device performing the DT function does not send the DT signal on the time-frequency resource C, and a device performing the CW function does not send the CW signal on the time-frequency resource C.

[0186] In some embodiments, a DCI indicates a time-frequency resource for performing DT, as well as CW and / or UR functions. The second device sends a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource, does not send an ES signal and / or a CW signal on the first time-frequency resource, and does not receive a UR signal on the first time-frequency resource; sends a CW signal to the A-IOT device or the A-IOT device group on the second time-frequency resource, and / or receives a UR signal backscattered by the A-IOT device or the A-IOT device group on the second time-frequency resource, and does not send an ES signal and / or a DT signal on the second time-frequency resource. The second device has a DT function, and / or the second device has a CW function and / or a UR function. The first information indicates that the second device with the DT function sends a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource, and the second device with the CW function and / or the UR function sends a CW signal to the A-IOT device or the A-IOT device group on the second time-frequency resource and / or receives a UR signal backscattered by the A-IOT device or the A-IOT device group.

[0187] For example, a DCI instructs a device performing the DT function to send a DT signal on time-frequency resource A, and a device performing the CW and / or UR function to transmit a CW signal on time-frequency resource B and receive the uplink signal UR backscattered by A-IOT device type A or B. A device performing the ES function does not transmit an ES signal on time-frequency resource A, a device performing the CW function does not transmit a CW signal on time-frequency resource A, and a device performing the UR function does not receive an UR signal on time-frequency resource A; a device performing the ES function does not transmit an ES signal on time-frequency resource B, and a device performing the DT function does not transmit a DT signal on time-frequency resource B.

[0188] In the above embodiment, the device that performs the CW function and the device that performs the UR function may be the same device or different devices.

[0189] In some embodiments, a DCI indicates a time-frequency resource for performing DT and UR functions. The second device sends a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource, does not send an ES signal and / or a CW signal on the first time-frequency resource, and does not receive a UR signal on the first time-frequency resource; receives a UR signal actively sent by the A-IOT device or the A-IOT device group on the second time-frequency resource, and does not send an ES signal and / or a DT signal on the second time-frequency resource. The second device has a DT function, and / or the second device has a UR function. The first information indicates that the second device with the DT function sends a DT signal to the A-IOT device or the A-IOT device group on the first time-frequency resource, and the second device with the UR function receives the UR signal actively sent by the A-IOT device or the A-IOT device group on the second time-frequency resource.

[0190] For example, a DCI instructs a device performing the DT function to transmit a DT signal on time-frequency resource A, and a device performing the UR function to receive an uplink signal UR proactively transmitted by an A-IOT device type C on time-frequency resource C. A device performing the ES function does not transmit an ES signal on time-frequency resource A, a device performing the CW function does not transmit a CW signal on time-frequency resource A, and a device performing the UR function does not receive an UR signal on time-frequency resource A; a device performing the ES function does not transmit an ES signal on time-frequency resource C, a device performing the DT function does not transmit a DT signal on time-frequency resource C, and a device performing the CW function does not transmit a CW signal on time-frequency resource C.

[0191] In the above embodiment, the second device communicates with the A-IOT device or A-IOT device group based on the first time-frequency resource indicated by the received first information, thereby coordinating the sending and receiving of the A-IOT device, thereby supporting efficient data transmission of the A-IOT device.

For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and steps 2101+2102 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0211] The device that performs one or more of the above-mentioned ES, DT, CW or UR functions may be a UE, a relay or a base station, etc. A device may support only one of the above-mentioned functions. Alternatively, a device may also support multiple functions at the same time. Alternatively, a device may also support all of the above-mentioned functions at the same time. The device that performs one of the above-mentioned functions may be one or more. In order to support effective communication with A-IOT devices, the network needs to coordinate the behavior of the devices that perform the above-mentioned ES, DT, CW or UR functions. The device responsible for coordinating the above-mentioned ES, DT, CW or UR functions may be one of the devices that perform the above-mentioned ES, DT, CW or UR functions on the A-IOT device. Alternatively, the device responsible for coordinating the above-mentioned ES, DT, CW or UR functions may also be other devices, such as a base station.

[0212] For A-IOT device types A and B, the resource allocation for transmitting the CW and receiving the UR for the uplink transmission backscattered by the A-IOT device must be consistent. In particular, the start time of the CW can be earlier than the UR by a timing advance. The timing advance can be predefined or configured by RRC signaling. For example, the CW within the timing advance can be used to activate the internal circuitry of the A-IOT device type A. If the start time of the CW and the UR is the same, the receiving device may actually receive the uplink signal backscattered by the A-IOT device type A later than the start time.

[0213] In order to schedule downlink transmission of one or a group of A-IOT devices, it is necessary to stop transmitting ES signals and CW to the A-IOT devices. Otherwise, the ES signals and CW will interfere with the downlink transmission.

[0214] To schedule one or a group of A-IoT devices, type A and B, for uplink transmission using CW backscatter, it is necessary to stop transmitting the ES signal and downlink information (DT) to the A-IoT device. Otherwise, the ES signal and DT will be superimposed on the CW, interfering with the uplink transmission to the receiving A-IoT device. To schedule A-IoT device type C for active uplink transmission, it is necessary to stop transmitting downlink information (DT) to the A-IoT device.

[0215] Example 1:

[0216] For one or a group of A-IoT devices, one or more devices may perform the same function of the above-mentioned ES, DT, CW or UR functions. A device may perform one or more functions of the above-mentioned ES, DT, CW or UR functions. The time-frequency resources allocated for the ES, DT, CW or UR functions may be semi-statically configured or dynamically scheduled by downlink control information (DCI). Alternatively, after configuring the time-frequency resources for the ES, DT, CW or UR functions, the DCI may be further transmitted to send information indicating activation or deactivation of the time-frequency resources for the ES, DT, CW or UR functions. The resource configuration method may include the following schemes:

[0217] 1. One DCI may indicate the time-frequency resources of only one of the above ES, DT, CW, or UR functions. That is, multiple DCIs need to be sent to indicate the time-frequency resources of all the above ES, DT, CW, or UR functions.

[0218] In some embodiments, one first information indicates the time-frequency resources of one function, and the first device needs to send multiple first information to one second device to indicate the time-frequency resources of all functions.

[0219] 2. One DCI can indicate the time-frequency resources for multiple of the ES, DT, CW, or UR functions. In this case, multiple DCIs are still required to indicate the time-frequency resources for all of the ES, DT, CW, or UR functions. For example, one DCI can indicate the time-frequency resource allocation for both the CW and UR functions.

[0220] In some embodiments, one first information indicates time-frequency resources of multiple functions, and the first device needs to send multiple first information to the second device to indicate the time-frequency resources of all functions.

[0221] 3. One DCI can indicate the time-frequency resources of all the above ES, DT, CW or UR functions.

[0222] In some embodiments, a first information indicates time-frequency resources for all functions, and a first device sends the first information to a second device, and the second device can perform all functions.

[0223] 4. A DCI is sent to a single UE. A DCI may indicate the time-frequency resources for only one of the UEs performing the aforementioned ES, DT, CW, or UR functions. If a UE performs two or more functions simultaneously, the resources for these two or more functions may be indicated simultaneously using a single DCI. For example, if a UE can simultaneously support CW transmission and reception of backscattered uplink signals (UR), the CW and UR resources may be indicated using a single DCI.

[0224] In some embodiments, a first message instructs a specific second device to use specific time-frequency resources to perform a corresponding function. The first message carries information about the second device. The first device knows the capabilities of the second device and sends corresponding resources to the corresponding second device.

[0225] 5. A DCI can be sent to one or more UEs. A DCI can indicate the time-frequency resources of one, multiple, or all UEs performing the above ES, DT, CW, or UR functions.

[0226] In some embodiments, a first information indicates a time-frequency resource of a function, and the first device sends the first information to multiple second devices. The multiple second devices can use the time-frequency resource to perform the same function.

[0227] In some embodiments, a first information indicates time-frequency resources for multiple functions. The first device sends the first information to different second devices. The first information does not distinguish which second device it is for. Each second device can use the same time-frequency resources to perform different functions, such as using the first time-frequency resources to send CW and receive backscattered UR.

[0228] In some embodiments, a first information indicates time-frequency resources for all functions, and the first device sends the first information to multiple second devices, and each second device can perform all functions.

[0229] For solutions 2, 3, and 5 above, multiple UEs may be configured to detect the same DCI. For example, the CRC of this DCI may be masked with the C-RNTI shared by these multiple UEs. Furthermore, if multiple devices are configured to perform the same ES, DT, CW, or UR function, then solutions 1, 2, 3, 4, and 5 above may need to support the possibility that multiple UEs may be configured to detect the same DCI.

[0230] Example 2:

[0231] In order to coordinate the behavior of multiple devices that perform the above-mentioned ES, DT, CW or UR functions, the base station sends a DCI to indicate the resources of at least one of the above-mentioned ES, DT, CW or UR functions. After multiple devices detect a DCI, they adjust their own behavior according to the control information carried by the DCI. For one or a group of A-IoT devices, one or more devices may perform the same function of the above-mentioned ES, DT, CW or UR functions. A device may be one or more functions that perform the above-mentioned ES, DT, CW or UR functions. In this method, multiple devices need to be configured to detect the same DCI. For example, the CRC of a DCI can be masked with the C-RNTI common to the multiple devices.

[0232] 1. A DCI may indicate that a device performing the DT function is performing a downlink transmission to an A-IoT device on time-frequency resource A. The device performing the DT function may be the device sending the DCI, such as a base station, or other device. The device performing the DT function is performing a downlink transmission to the A-IoT device on time-frequency resource A. After detecting the DCI, the device performing the ES, CW, or UR function does not transmit an ES on time-frequency resource A, does not transmit a CW on time-frequency resource A, and does not receive an uplink UR transmission from the A-IoT device on time-frequency resource A.

[0233] 2. A DCI may be an instruction for a device that performs CW and / or UR functions to transmit CW on time-frequency resource B and receive the uplink signal backscattered by A-IoT device type A or B. The device that performs CW and / or UR functions may be a device that sends the DCI, such as a base station, or other device. The device that performs the CW function transmits CW on time-frequency resource B; the device that performs the UR function receives the uplink signal backscattered by A-IoT device type A or B on time-frequency resource B. The devices that perform CW and UR functions may be the same device or different devices. After detecting the DCI, the device that performs the ES or DT function does not transmit ES on time-frequency resource B; and does not transmit downlink information DT to the A-IoT device on time-frequency resource B.

[0234] 3. A DCI may indicate that a device performing the UR function receives an uplink signal from an A-IoT device type C on time-frequency resource C. The device performing the UR function may be the device that sends the DCI, such as a base station, or other device. The device performing the UR function receives an uplink signal from an A-IoT device type C on time-frequency resource C. After detecting the DCI, the device performing the ES, CW, or DT function does not transmit an ES on time-frequency resource C; does not transmit a CW on time-frequency resource C; and does not transmit downlink information DT to the A-IoT device on time-frequency resource C.

[0235] 4. A DCI may instruct a device performing the DT function to perform a downlink transmission to an A-IoT device on time-frequency resource A, and instruct a device performing the CW and / or UR function to transmit a CW on time-frequency resource B and receive uplink signals backscattered from A-IoT device type A or B. The device performing the DT, CW, and / or UR functions may be the device that sends the DCI, such as a base station or other device. On time-frequency resource A, the device performing the DT function performs a downlink transmission to the A-IoT device on time-frequency resource A. After detecting the DCI, the device performing the ES, CW, or UR function does not transmit an ES on time-frequency resource A, does not transmit a CW on time-frequency resource A, and does not receive uplink transmissions (UR) from A-IoT devices on time-frequency resource A. On time-frequency resource B, the device performing the CW function transmits a CW on time-frequency resource B, and the device performing the UR function receives uplink signals backscattered from A-IoT device type A or B on time-frequency resource B. The CW and UR functions may be performed by the same UE or different devices. After detecting the DCI, the device performing the ES or DT function does not transmit the ES on the time-frequency resource B, and does not transmit the downlink information DT to the A-IoT device on the time-frequency resource B.

[0236] 5. A DCI may instruct a device performing the DT function to perform a downlink transmission to an A-IoT device on time-frequency resource A, and instruct a device performing the UR function to receive uplink signals from A-IoT device type C on time-frequency resource C. The device performing the DT and / or UR function may be the device that sends the DCI, such as a base station or other device. On time-frequency resource A, the device performing the DT function performs a downlink transmission to the A-IoT device on time-frequency resource A. Upon detecting the DCI, the device performing the ES, CW, or UR function does not transmit an ES on time-frequency resource A, does not transmit a CW on time-frequency resource A, and does not receive uplink transmissions (UR) from the A-IoT device on time-frequency resource A. On time-frequency resource C, the device performing the UR function receives uplink signals from A-IoT device type C on time-frequency resource C. Upon detecting the DCI, the device performing the ES, CW, or DT function does not transmit an ES on time-frequency resource C, does not transmit a CW on time-frequency resource C, and does not transmit downlink information (DT) to the A-IoT device on time-frequency resource C.
