[0073] In some embodiments, the access network device, the core network device, or the network device can be replaced by a terminal. For example, the various embodiments of the present disclosure can also be applied to a structure in which the communication between the access network device, the core network device, or the network device and the terminal is replaced by communication between multiple terminals (for example, device-to-device (D2D), vehicle-to-everything (V2X), etc.).

[0078] 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.

[0079] A-IoT device type A requires a relatively high received signal power to activate its internal circuitry, for example, approximately -20dBm, resulting in low downlink reception sensitivity. Furthermore, because A-IoT device type A does not support reflection amplification, its backscattered uplink signal power is limited, resulting in poor uplink transmission performance. A-IoT device type B supports energy storage and can activate its internal circuitry with a lower received signal power than A-IoT device type A, for example, approximately -40dBm. Although its downlink reception sensitivity is improved, A-IoT device type B's support for reflection amplification increases the backscattered uplink signal power, correspondingly improving uplink transmission performance. A-IoT device type C generally supports more energy storage, resulting in downlink reception sensitivity comparable to or even higher than that of A-IoT device type B. Because A-IoT device type C supports active uplink transmission and is not restricted to CW, its uplink transmission performance is superior. Based on the above analysis, in terms of processing power, device type C > device type B > device type A. When probing A-IoT devices, the characteristics of the various A-IoT device types described above must be considered. Within a certain range, the number of A-IoT devices can be extremely large, far exceeding that of existing NR systems. When sending a downlink probe command, multiple A-IoT devices may be sending uplink transmissions, causing uplink transmission collisions.

[0080] Therefore, the present disclosure proposes a communication method and device, a communication system, a communication device, and a storage medium to group A-IOT devices. Each search command is only targeted at one or more groups of A-IOT devices, thereby reducing collisions.

[0081] 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.).

[0082] First, a brief introduction to the relevant terms in this application:

[0083] 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.

[0084] 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.

[0085] CW: 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 the present 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 that enable an A-IOT device or an A-IOT device group to send an uplink signal based on backscattering. The names of excitation and continuous wave can be interchangeable.

[0086] UR: Uplink Receiving (UR) signal. The UR function is used to receive uplink information backscattered by A-IOT devices, or receive uplink information actively transmitted by A-IOT devices.

[0107] 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:

[0108] Step 2101: The first device configures downlink transmission parameters.

[0109] In some embodiments, downlink transmission parameters are related to the grouping of A-IOT devices. The following describes different ways to group A-IOT devices:

[0110] In some embodiments, one or more A-IOT device groups may be A-IOT device groups capable of actively performing uplink transmission.

[0111] In some embodiments, one or more A-IOT device groups may be A-IOT device groups that cannot actively perform uplink transmission.

[0112] For example, the A-IOT devices are grouped according to whether they actively transmit uplink. For example, A-IOT devices of types A and B are grouped together, and type C is grouped together. Using this method, uplink transmission based on backscattering or active uplink transmission can be scheduled based on the type of a group of A-IOT devices being explored.

[0113] In some embodiments, one or more A-IOT device groups may be an A-IOT device group that supports energy storage or an A-IOT device group that does not support energy storage.

[0114] For example, A-IOT devices are grouped according to whether they support energy storage. For example, A-IOT devices of type A are grouped together, and types B and C are grouped together.

[0115] In some embodiments, one or more A-IOT device groups may be an A-IOT device group that supports energy storage and the amount of stored energy is lower than a preset threshold or an A-IOT device group that supports energy storage and the amount of stored energy is higher than a preset threshold.

[0116] For example, A-IOT devices are grouped according to their energy storage capacity, for example, A-IOT devices of type A are grouped together, and types B and C are grouped together, or A-IOT devices of type A are grouped together, type B are grouped together, and type C are grouped together.

[0117] In some embodiments, one or more A-IOT device groups may be an A-IOT device group that supports active uplink transmission and supports energy storage, or an A-IOT device group that does not support active uplink transmission and does not support energy storage, or an A-IOT device group that does not support active uplink transmission but supports energy storage.

[0118] For example, A-IOT devices can be grouped based on whether they actively transmit uplink and whether they support energy storage. For example, A-IOT devices of type A are grouped together, type B is grouped together, and type C is grouped together. This grouping method allows us to distinguish the three different A-IOT device types and use the most appropriate uplink transmission scheduling method. Although A-IOT devices of types A and B both transmit uplink based on backscatter, their appropriate uplink and downlink transmission parameters are different.

[0119] In some embodiments, one or more A-IOT device groups may be an A-IOT device group that supports active uplink transmission and supports energy storage but the amount of energy storage is lower than a preset threshold, or an A-IOT device group that supports active uplink transmission and supports energy storage and the amount of energy storage is higher than or equal to a preset threshold.

[0120] In some embodiments, one or more A-IOT device groups may be an A-IOT device group that does not support active uplink transmission but supports energy storage and the amount of energy storage is lower than a preset threshold, or an A-IOT device group that does not support active uplink transmission but supports energy storage and the amount of energy storage is higher than or equal to a preset threshold, or an A-IOT device group that does not support active uplink transmission and does not support energy storage.

[0121] For example, A-IOT devices are grouped based on whether they actively transmit uplink, whether they support energy storage, and the amount of energy storage. For example, A-IOT devices of type A are grouped together, type B devices are divided into two groups based on the amount of energy storage, and type C devices are divided into two groups based on the amount of energy storage. This grouping method allows for scheduling uplink transmissions and controlling the duration of uplink transmissions based on the most appropriate parameters by specifying the device type to be explored in the exploration command.

[0122] In some embodiments, one or more A-IOT device groups may be an A-IOT device group that supports active uplink transmission but has an energy storage capacity lower than a preset threshold, or an A-IOT device group that supports active uplink transmission and has an energy storage capacity higher than or equal to a preset threshold, or an A-IOT device group that does not support active uplink transmission but has an energy storage capacity lower than a preset threshold, or an A-IOT device group that does not support active uplink transmission and has an energy storage capacity higher than or equal to a preset threshold.

[0123] In some embodiments, there can be multiple preset thresholds. In other words, grouping according to energy storage can be to further divide the A-IOT devices into four groups according to the first preset threshold, the second preset threshold, and the third preset threshold, or to divide the A-IOT devices into five groups according to the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold, and so on, but is not limited to this.

[0124] For example, A-IOT devices are grouped based on whether they are actively transmitting uplink and their energy storage capacity. For example, A-IOT devices of type A are grouped together, type B together, and type C together. Type B devices are divided into one or more groups based on their energy storage capacity, and type C devices are divided into one or more groups based on their energy storage capacity. This grouping method allows for scheduling uplink transmissions and controlling the duration of uplink transmissions according to the most appropriate parameters by specifying the device type to be explored in the exploration command.

[0125] In some embodiments, based on the above grouping, other methods may be used to further group the A-IOT device groups, which is not limited in this disclosure.

[0126] For example, after grouping A-IOT devices according to whether they support energy storage, that is, device type A is one group, and device types B and C are one group. Then, the device type A group is further divided into two groups according to the level of latency, and the device type B and type C groups are further divided into two groups according to the level of latency. Among them, the latency is higher than or equal to the preset latency and the latency is lower than the preset latency.

[0127] For example, after grouping according to whether the A-IOT devices actively transmit uplink, that is, device types A and B are in one group, and device type C is in another group, the groups of device types A and B are further divided into two groups according to the device identification ID, and the group of device type C is further divided into two groups according to the device ID.

[0128] In some embodiments, downlink transmission parameters may be configured based on a preset A-IOT device group capability.

[0129] For example, the downlink probe command can configure downlink transmission parameters according to the preset A-IOT device group capabilities. For example, if A-IOT device type A is used as the preset A-IOT device group, the downlink transmission parameters of the downlink probe command are set according to type A.

[0130] In some embodiments, downlink transmission parameters may be configured based on the minimum capabilities of one or more A-IOT device groups.

[0131] For example, the downlink search command can set downlink transmission parameters according to the device type with the lowest capability in one or more A-IOT device groups. For example, when grouping according to whether or not uplink transmission is active, device type C is in one group, and device types A and B are in another group. When searching for device type C, fewer time-frequency resources and / or lower transmission capabilities are allocated, which may prevent types A and B from successfully receiving the search command; when searching for device types A and B, more time-frequency resources and / or higher transmission power can be allocated according to the needs of device type A; when grouping according to energy storage capacity based on the above grouping, device types A and B are divided into different groups and searched separately, and different downlink transmission parameters can be configured for different groups.

[0132] In some embodiments, the downlink transmission parameters may be configured based on the minimum capabilities of one or more A-IOT device groups discovered during the first time period.

[0133] For example, the downlink search command can set the downlink transmission parameters according to the device type with the lowest capability among one or more groups of A-IOT devices to be searched within a period of time, thereby ensuring that within the first time period, all interested A-IOT devices can normally receive the downlink search command. For example, when grouping according to whether they support energy storage, device type A is one group, and device types B and C are one group. When searching for device type A, the corresponding time-frequency resources and / or transmission power are allocated according to the requirements of device type A. When searching for device types B and C, the corresponding downlink transmission parameters are configured according to the device type with the lowest capability among B and C, so that both device types B and C can normally receive the downlink search command.

[0134] In the above embodiment, the first device configures downlink transmission parameters according to different solutions based on different grouping methods of A-IOT devices to achieve downlink transmission to different A-IOT device groups.

[0135] Step 2102: The first device sends a first message.

[0136] In some embodiments, the first message is used to search for one or more A-IoT device groups, where searching may refer to "discovery" or "paging."

[0137] In some embodiments, the A-IOT device group is grouped according to the different grouping methods listed in step 2101.

[0138] For example, the first message is a downlink probe command. The number of first messages is not limited and can be one downlink probe command or multiple downlink probe commands. A probe command can include only one continuously transmitted downlink message, or the downlink probe command can include multiple time-division multiplexed downlink messages. There can be time intervals between the multiple time-division multiplexed downlink messages. As shown in FIG3 , downlink probe 1 and downlink probe 2 can include the same information field, or they can include different information fields.

[0139] In some embodiments, the first message includes uplink transmission parameters, and the uplink transmission parameters are used for one or more A-IOT device groups to backscatter or actively send uplink messages to the first device.

[0140] In some embodiments, the uplink transmission parameters in the first message are uplink transmission parameters configured by the first device for the one or more A-IOT device groups being explored, and are used to schedule uplink transmissions of the A-IOT devices.

[0141] In some embodiments, the first message includes identification of one or more A-IOT device groups.

[0142] For example, the first message includes the identifier of the A-IOT device group, that is, the downlink probe command indicates the type of device being probed. When grouped according to whether uplink transmission is active, whether energy storage is supported, and the amount of energy storage, device type A is one group, type B is divided into two groups according to the amount of energy storage, and type C is divided into two groups according to the amount of energy storage. By indicating the type of device being probed in the probe command, uplink transmission can be scheduled according to the most suitable parameters and the duration of uplink transmission can be controlled.

[0143] In some embodiments, the first message includes uplink transmission parameters and identifiers of one or more A-IOT device groups.

[0144] For example, the downlink probe command includes both uplink transmission parameters for the probed A-IOT device to set its uplink transmission parameters, and an identifier of the probed A-IOT device group to set the most suitable uplink transmission parameters for the probed A-IOT device according to its device type.

[0145] In the above embodiment, the first device searches for the A-IOT device group by sending the first message, and schedules the uplink transmission of the A-IOT device by configuring different uplink transmission parameters.

[0146] Step 2103: The A-IOT device sets uplink transmission parameters.

[0147] In some embodiments, the A-IOT device belongs to one or more A-IOT device groups that the first device is looking for.

[0148] In some embodiments, the A-IOT device sets an uplink transmission parameter of the A-IOT device based on the uplink transmission parameter of the first message.

[0149] For example, after receiving the downlink probing command, the A-IOT device being probed may set uplink transmission parameters according to the scheduling of the downlink probing command, or the A-IOT device being probed may also set uplink transmission parameters according to the following method.

[0150] In some embodiments, the uplink transmission parameters may be set based on the capabilities of a preset A-IOT device group.

[0151] For example, the uplink transmission parameters can be set based on the backscattered transmission signal. For example, with A-IOT device type A as the default device type, CW transmission and reception of backscattered uplink signals are scheduled. If the device type with the lowest capability within the coverage area is known, the backscattered uplink transmission or active uplink transmission, as well as the corresponding uplink transmission parameters, can be set according to this known device type.

[0152] In some embodiments, uplink transmission parameters may be set based on the lowest capabilities of one or more A-IOT device groups.

[0153] For example, the uplink transmission parameters can be set according to the device type with the lowest capability among one or more groups of A-IOT devices currently being explored. For example, when exploring only device type C, fewer time-frequency resources and / or lower transmission power can be allocated; when exploring device types A and B, more time-frequency resources and / or higher transmission power can be scheduled according to the needs of device type A; when exploring device types B and C, the uplink transmission parameters can be set based on the backscattered transmission uplink signal, that is, with A-IOT device type B as the default device type, CW transmission and reception of backscattered uplink signals are scheduled. When device types A and B are divided into different groups and explored separately, different uplink transmission parameters can be configured according to different methods.

[0154] In some embodiments, uplink transmission parameters may be set based on actual capabilities reported by a group of A-IOT devices.

[0155] For example, the uplink transmission parameters are set according to the actual capabilities of an A-IOT device. When searching for device type A, an A-IOT device of device type A reports its actual capabilities, and the A-IOT device can set the uplink transmission parameters according to the reported actual capabilities.

[0156] In some embodiments, the uplink transmission parameters may be set based on the lowest capability of the actual capabilities reported by one or more A-IOT device groups.

[0157] For example, when one or more A-IOT device groups report actual capabilities, uplink transmission parameters are set according to the lowest capability among the reported actual capabilities, and the discovered A-IOT device performs uplink transmission according to this uplink transmission parameter.

[0158] In some embodiments, the uplink transmission parameters may be different uplink transmission parameters set for different A-IOT device groups.

[0159] For example, the uplink transmission parameters are set using the same A-IOT device type, for example, the uplink transmission parameters are set according to the A-IOT device type with the lowest capability, or the uplink transmission parameters are set according to the device type with the lowest capability in one or more groups of A-IOT devices currently being explored, or the uplink transmission parameters are set according to the device type with the lowest capability in one or more groups of A-IOT devices currently being explored, which can facilitate the multiplexing of uplink transmissions of multiple A-IOT devices.

[0160] In some embodiments, when the same A-IOT device needs to set multiple uplink transmission parameters, different uplink transmission parameters can be set according to different methods.

[0161] For example, assuming that a detected A-IOT device sends multiple uplink messages, for example, uplink information 1 and uplink information 2 in FIG4 may originate from the same A-IOT device, and the first uplink information and subsequent uplink information sent by the detected A-IOT device may use different uplink transmission parameters. As shown in FIG4 , uplink information 1 may be used to set the uplink transmission parameters according to the device type with the lowest capability among one or more groups of A-IOT devices currently being detected. Assuming that uplink information 1 indicates the detailed capability parameters of the A-IOT device, uplink information 2 may determine the uplink transmission parameters according to the actual capability of this A-IOT device.

[0162] In the above embodiment, the discovered A-IOT device sets uplink transmission parameters based on the first message to implement uplink transmission.

[0163] Step 2104: The A-IOT device backscatters or actively sends an uplink signal to the first device.

[0164] In some embodiments, the A-IOT device backscatters or actively sends an uplink signal to the first device according to the uplink transmission parameters.

[0165] In some embodiments, a first message can trigger an uplink transmission of an A-IOT device. As shown in Figure 3, a downlink probe command triggers an uplink transmission of an A-IOT device. The probed A-IOT device sets the uplink transmission parameters according to the downlink probe command, and backscatters or actively sends an uplink signal to the first device based on the downlink probe command.

[0166] In some embodiments, a first message can trigger uplink transmissions of multiple A-IOT devices. As shown in Figure 4, a downlink probe command triggers uplink transmissions of three A-IOT devices. Under the premise that no collision occurs, these three uplink messages are time-divided. Based on the assumption of the same device type, the timing of the start and end of multiple uplink transmissions can be determined.

[0167] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2104. For example, step 2101 can be implemented as an independent embodiment, step 2102 can be implemented as an independent embodiment, and so on, but the present invention is not limited thereto. Steps 2101+2102, step 2102+2103, step 2101+2102+2103, and step 2101+2102+2103+2104 can be implemented as independent embodiments, but the present invention is not limited thereto.

[0168] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0169] In summary, the present disclosure provides a communication method in which a first message is sent by a first device to search for one or a group of A-IOT devices. By grouping A-IOT devices in different ways, grouped search for A-IOT devices is achieved, and corresponding uplink transmission parameters are set based on the downlink search of the first device to avoid collisions between uplink transmission messages from multiple A-IOT devices.

[0196] In some embodiments, the above method may include the method described in the above embodiments of the first device side and the A-IOT device side, which will not be repeated here.

[0198] The following are specific solutions provided by the embodiments of the present disclosure:

[0199] To support data transmission of A-IOT devices, a device in the network can support one or more of the following functions: (1) CW excitation function; (2) ES function; (3) DT function; (4) UR function.

[0200] FIG3 is a schematic diagram of polling A-IoT devices within a certain range. It is assumed here that the polling is performed according to device types A and B, so the transmission of CW is shown in FIG3. If the polling is performed according to device type C, there is no need to transmit CW. In FIG3, the polling device sends a downlink polling command to poll a group of A-IoT devices. After receiving the polling command, one of the A-IoT devices in the group of A-IoT devices determines whether the A-IoT device can respond to the downlink polling command according to a certain randomization method, that is, sends uplink information 1. For example, an A-IoT device can generate a random number and set a backoff counter. Only when the backoff counter returns to zero, the A-IoT device transmits downlink information 1. The embodiment of the present disclosure does not limit the specific randomization method. After receiving uplink information 1, the polling device can continue to perform downlink and uplink transmissions with the same A-IoT device, that is, the downlink poll 2 and uplink information 2 in FIG3 can be for the A-IoT device that sent uplink information 1, which is equivalent to unicast. Alternatively, after receiving the uplink information 1, the inquiry device may send a downlink inquiry 2 to inquire about other A-IoT devices, and the other A-IoT devices may feed back the uplink information 2. Figure 3 only illustrates two downlink and uplink interactions. The embodiment of the present disclosure does not limit a downlink inquiry command to trigger more downlink and uplink interactions. In Figure 3, a downlink inquiry command may include only one continuously transmitted downlink message, or the downlink inquiry command may also include multiple time-division multiplexed downlink messages. There may be a time interval between the multiple time-division multiplexed downlink messages. In Figure 3, the downlink inquiry 1 and the downlink inquiry 2 may include the same information field, or may include different information fields.

[0201] The basis for grouping A-IOT devices can include various criteria:

[0202] The first method for grouping A-IoT devices is to group them based on whether they are actively transmitting uplink. For example, A-IoT devices of types A and B are grouped together, and type C is grouped together. This method allows scheduling of either backscatter-based uplink transmissions or active uplink transmissions based on the type of the A-IoT device being polled.

[0203] The second method of grouping A-IoT devices is to group them based on whether they support energy storage. For example, A-IoT devices of type A are grouped together, and types B and C are grouped together.

[0204] A third method for grouping A-IoT devices is to group them by their energy storage capacity. For example, A-IoT devices of type A could be grouped together, and types B and C could be grouped together. Alternatively, A-IoT devices of type A could be grouped together, type B could be grouped together, and type C could be grouped together.

[0205] A fourth method for grouping A-IoT devices is to group them based on whether they actively transmit uplink and whether they support energy storage. For example, A-IoT devices of type A are grouped together, type B together, and type C together. This grouping method distinguishes the three UE types and adopts the most appropriate uplink scheduling method. Although both A-IoT devices of type A and B use backscatter for uplink transmission, their appropriate uplink and downlink transmission parameters differ.

[0206] A fifth method for grouping A-IoT devices is to group them based on whether they actively transmit uplinks, whether they support energy storage, and the amount of energy storage. For example, A-IoT devices of type A are grouped together, type B devices are divided into two groups based on their energy storage capacity, and type C devices are divided into two groups based on their energy storage capacity. This grouping method allows uplink transmissions to be scheduled and their duration to be controlled according to the most appropriate parameters by specifying the device type in the query command.

[0207] The sixth method of grouping A-IoT devices is to group them according to whether the A-IoT devices actively transmit uplink and their energy storage capabilities. For example, A-IoT device type A is in one group, type B is in one group, and type C is in one group. Using this grouping method, the three UE types can be distinguished and the most suitable scheduling method for uplink transmission can be adopted. For A-IoT device types A and B, although both perform uplink transmission based on backscattering, their suitable uplink and downlink transmission parameters are different. For example, A-IoT device type A is in one group, type B is divided into one or more groups based on the amount of energy storage, and type C is divided into one or more groups based on the amount of energy storage. Using this grouping method, by indicating the type of device being queried in the query command, uplink transmission can be scheduled according to the most suitable parameters and the duration of uplink transmission can be controlled.

[0208] Using the above method, when a group of A-IoT devices is polled using a downlink polling command, the group of A-IoT devices has the same or similar downlink transmission capabilities, thereby facilitating adjustment of uplink and downlink transmission parameters. The disclosed embodiments provide some criteria for grouping A-IoT devices, and other criteria can also be used to further group the divided A-IoT device groups without limitation.

[0209] Using this method, downlink probe commands can be transmitted using one of the following methods:

[0210] The first method is to use a more conservative approach for downlink probe commands, setting downlink transmission parameters based on the lowest-capable A-IoT device type. For example, use A-IoT device type A as the default device type to set downlink transmission parameters for probe commands. If the lowest-capable device type within coverage is known, the downlink transmission parameters for probe commands can be set based on this known device type.

[0211] Second, the downlink query command can also set downlink transmission parameters based on the lowest-capable device type in one or more groups of A-IoT devices being queried. For example, when querying device type C, fewer time-frequency resources and / or lower transmission power can be allocated, which may result in device types A and B failing to successfully receive the query command. When querying device types A and B, more time-frequency resources and / or higher transmission power can be allocated based on the needs of device type A. When device types A and B are divided into different groups and queried separately, different downlink transmission parameters can be configured accordingly.

[0212] The third scenario: Assuming the downlink query command is also used by the A-IoT device to count its backoff counter, the downlink query command can set downlink transmission parameters based on the lowest-capability device type among one or more groups of A-IoT devices to be queried within a time period, thereby ensuring that all interested A-IoT devices can properly receive the downlink query command and count within the time period. Here, assuming that multiple downlink messages, such as downlink query 1 and downlink query 2 in Figure 4, are actually associated with the same A-IoT device, other A-IoT devices can only count its backoff counter once. Downlink information transmitted unicast to an A-IoT device can use different downlink transmission parameters than other multicast / broadcast downlink information. For example, the transmission parameters of downlink query 2 in Figure 4 can be different from those of downlink query 1. Downlink query 2 can determine the downlink transmission parameters based on the actual capabilities of the A-IoT device.

[0213] Using this method, the downlink query command can schedule the uplink transmission of the A-IoT device using the following method:

[0214] The first approach is to adopt a more conservative approach and set uplink transmission parameters based on the lowest-capability A-IoT device type. Specifically, uplink transmission parameters can be set based on the backscattered uplink signal. For example, using A-IoT device type A as the default device type, schedule CW transmission and reception of backscattered uplink signals. If the lowest-capability device type within the coverage area is known, backscattered uplink transmission or active uplink transmission, along with the corresponding uplink transmission parameters, can be set based on this known device type.

[0215] The second method is to set the uplink transmission parameters according to the device type with the lowest capability among one or more groups of A-IoT devices currently being polled. For example, when polling only device type C, fewer time-frequency resources and / or lower transmission power can be allocated; when polling device types A and B, more time-frequency resources and / or higher transmission power can be scheduled according to the needs of device type A; when polling device types B and C, uplink transmission parameters can be set based on the backscattered uplink signal, that is, with A-IoT device type B as the default device type, CW transmission and reception of backscattered uplink signals are scheduled. When device types A and B are divided into different groups and polled separately, different uplink transmission parameters can be configured accordingly.

[0216] The third type: Assume that an A-IoT device being queried sends multiple uplink messages. For example, uplink message 1 and uplink message 2 in Figure 4 may originate from the same A-IoT device. The first uplink message and subsequent uplink messages sent by the queried A-IoT device may use different uplink transmission parameters. Taking Figure 4 as an example, uplink message 1 may set the uplink transmission parameters according to the device type with the lowest capability among one or more groups of A-IoT devices currently being queried. Assuming that the uplink information 1 indicates the detailed capability parameters of the A-IoT device, uplink information 2 may determine the uplink transmission parameters according to the actual capabilities of this A-IoT device.

[0217] The fourth method is to determine the uplink transmission parameters according to the actual capabilities of the A-IoT device being queried.

[0218] Using this method, after receiving the downlink inquiry command, the A-IoT device being polled can set the uplink transmission parameters according to the scheduling of the downlink inquiry command. Alternatively, the A-IoT device being polled can also use the following methods to handle uplink transmission:

[0219] The first approach is to adopt a more conservative approach and set uplink transmission parameters based on the lowest-capability A-IoT device type. Specifically, uplink transmission parameters can be set based on the backscattered uplink signal. For example, using A-IoT device type A as the default device type, schedule CW transmission and reception of backscattered uplink signals. If the lowest-capability device type within the coverage area is known, backscattered uplink transmission or active uplink transmission, along with the corresponding uplink transmission parameters, can be set based on this known device type.

[0220] The second method is to set the uplink transmission parameters according to the device type with the lowest capability among one or more groups of A-IoT devices currently being polled. For example, when polling only device type C, fewer time-frequency resources and / or lower transmission power can be allocated; when polling device types A and B, more time-frequency resources and / or higher transmission power can be scheduled according to the needs of device type A; when polling device types B and C, uplink transmission parameters can be set based on the backscattered uplink signal, that is, with A-IoT device type B as the default device type, CW transmission and reception of backscattered uplink signals are scheduled. When device types A and B are divided into different groups and polled separately, different uplink transmission parameters can be configured accordingly.

[0221] The third type: Assume that an A-IoT device being queried sends multiple uplink messages. For example, uplink message 1 and uplink message 2 in Figure 4 may originate from the same A-IoT device. The first uplink message and subsequent uplink messages sent by the A-IoT device being queried may use different uplink transmission parameters. The subsequent uplink messages are unicast. Taking Figure 4 as an example, uplink message 1 may be set to the uplink transmission parameters according to the device type with the lowest capability among one or more groups of A-IoT devices currently being queried. Assuming that the uplink information 1 indicates the detailed capability parameters of the A-IoT device, uplink information 2 may determine the uplink transmission parameters according to the actual capabilities of this A-IoT device.

[0222] The fourth method is to determine the uplink transmission parameters according to the actual capabilities of the A-IoT device being queried.

[0223] In the above method, the uplink transmission parameters are set using the same A-IoT device type. For example, the uplink transmission parameters are set according to the A-IoT device type with the lowest capability, or the uplink transmission parameters are set according to the device type with the lowest capability in one or more groups of A-IoT devices currently being queried. This can facilitate the reuse of uplink transmissions of multiple A-IoT devices. One downlink query command can trigger uplink transmissions of multiple A-IoT devices. For example, as shown in Figure 4, one downlink query command can trigger uplink transmissions of three A-IoT devices. Under the premise that no collision occurs, the three uplink messages are time-divided. Based on the assumption of the same device type, it is relatively easy to determine the start and end timing of the multiple uplink transmissions.
