[0037] For ease of understanding, some content related to the embodiments of this application is described below:

[0038] 1: A-IoT device type

[0039] In the related technologies studied by A-IoT, environmental IoT devices are characterized according to the energy storage capacity of the environmental IoT devices and the ability to generate radio frequency signals for transmission. The A-IoT device has one of the following energy storage capabilities:

[0040] Storage capacity 1: No ability to store energy;

[0041] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible that E1 = E2;

[0042] Storage capacity 3: Energy can be stored up to E2 joules.

[0043] Relying on these storage capacities, the related technology considers the following set of environmental Internet of Things devices:

[0044] Device A: No energy storage, no independent signal generation / amplification, i.e., backscatter transmission;

[0045] Device B: Has energy storage, no independent signal generation, i.e., backscatter transmission, and the use of stored energy can include amplification of the reflected signal;

[0046] Device C: Has energy storage, has independent signal generation, i.e., active radio frequency components for transmission.

[0047] Devices with different energy storage capabilities also affect the transmission quality of the devices. Usually, devices with higher energy storage also mean higher receiving sensitivity or higher transmitting power. That is, the reliability of the receiving or transmitting link can be better guaranteed.

[0048] 2: AIoT service types

[0049] The main data or service types of A-IoT:

[0050] DO: Device-originated;

[0051] DT: Device-terminated;

[0052] DO data streams include DO autonomous (DO-A) and triggered DO device-terminated (DO-DTT) (DO traffic includes DO autonomous (DO-A), and DO device-terminated triggered (DO-DTT)).

[0053] Among them, DO and DT data indicate that the data stream originates from an A-IoT device (similar to a Radio Frequency Identification (RFID) tag) or is transmitted to an A-IoT device. For the data stream originating from an A-IoT device, i.e., DO data, it can be further classified as:

[0054] DO-A, that is, the AIoT device initiates data transmission autonomously. For example, it connects a large number of various sensors, which collect and actively report information about the environment, devices, and organisms when necessary;

[0055] DO-DTT, that is, a reader device such as a base station triggers the AIoT device to initiate data transmission. For example, asset identification, status reporting, and tracking are all DL-triggered reports. The reader triggers the inventory program to collect data from the tag. Since the data is generated or initiated in the IoT device, this service should be regarded as the tag initiating the DO service triggered by the control command on the Reader side.

[0056] 3: Reception of control information in the 3GPP NR system

[0057] In the 3rd Generation Partnership Project (3GPP) NR system, the base station can send downlink control information (DCI) at the physical layer, which is carried by the physical downlink control channel (PDCCH). DCI has various uses, such as scheduling the physical downlink shared channel (PDSCH), scheduling the physical uplink shared channel (PUSCH), scheduling the physical uplink control channel (PUCCH), triggering the physical random access channel (PRACH) for uplink, and sending and receiving uplink / downlink reference signals, such as the sounding reference signal (SRS) and the CSI reference signal (CSI-RS). DCI can also indicate power control, uplink / downlink configuration, cell dormancy, etc. DCI has various formats, corresponding to different uses. The DCI size for each format can be the same or different. For a specific format, the DCI size is uniquely determined.

[0058] To reduce the excessive burden of blind detection on user equipment (UE, i.e., the terminal) caused by multiple DCI sizes (especially the complexity of channel decoding), it is specified that the UE supports at most 4 different DCI sizes. When the base station configures multiple DCI formats, this limitation needs to be considered, and it is ensured that this limit is not exceeded by configuration or by performing size alignment according to predefined rules. For the case where multiple DCI formats correspond to the same size, there are usually identification bits in the DCI payload to distinguish which DCI format it is.

[0059] To support the PDCCH to achieve the target performance in different channel environments, the PDCCH supports multiple aggregation levels (AL), such as AL = 1, 2, 4, 8, and the PDCCH supports different repetition times (Repetition). In addition, to reduce the PDCCH blocking between different UEs, a PDCCH has multiple candidate positions, and the base station can flexibly select a suitable position to send the PDCCH.

[0060] Due to the existence of multiple ALs, multiple Repetition times, and multiple candidate positions, the UE needs to perform blind detection. To control the complexity of PDCCH blind detection, the protocol defines the maximum number of times of PDCCH blind detection.

[0061] The information transmission method, device, and related equipment provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0062] See Figure 2 , Figure 2 is a flowchart of an information transmission method provided by the embodiments of the present application. As Figure 2 shown, the information transmission method includes the following steps:

[0073] Among them, the power control information may include a power control indication. The carrier activation and deactivation information may be used to indicate the activation and deactivation of the carrier.

[0074] In one implementation, the AIoT function downlink signaling may refer to the AIoT function signaling sent by the control node, such as inventory related downlink signaling and command related downlink signaling, etc.

[0075] In one implementation, the AIoT function uplink signaling may refer to the AIoT function signaling sent by the AIoT device, such as inventory related uplink signaling and command related uplink signaling, etc.

[0076] In one implementation, the configuration information carried by the AIoT channel may refer to the high - layer configuration information other than the system message.

[0077] In one implementation, the uplink data may refer to the uplink data sent by the AIoT device. For example, it may be the data sent by the AIoT device to the control node.

[0078] In one implementation, the downlink data may refer to the downlink data received by the AIoT device. For example, it may be the data sent by the control node and received by the AIoT device.

[0079] In one implementation, the AIoT channel includes at least one of a first channel and a second channel.

[0080] In one implementation, the first channel carries at least one of the following information:

[0081] Information related to downlink or uplink transmission, including: time domain resources, frequency domain resources, modulation method, coding method, payload size, retransmission indication, chip length or chip rate, collision avoidance parameters, power control indication, activation and deactivation of carriers, etc.;

[0084] System messages;

[0097] In one implementation, the start of the first channel may also include a start symbol. The start symbol can at least assist in the reception of subsequent signals. For example, the first control information includes a start symbol, a preamble, and a payload part in sequence, and the AIOT device can determine coarse synchronization based on the start symbol for the reception of the preamble and the payload part.

[0098] In one implementation, the second channel includes a payload part, and the start of the second channel may also include a preamble sequence, which provides a time synchronization function or carries information.

[0099] It should be noted that compared with 3GPP terminals, the power consumption level, device complexity level, etc. of AIOT devices have decreased significantly, resulting in different capabilities between AIOT devices and 3GPP terminals. The existing 3GPP uplink and downlink channel designs cannot be directly applied to A-IOT devices.

[0116] The first device determines the channel structure type of the AIOT channel based on the first information, and determines whether the AIOT channel includes the first channel or the second channel based on the channel structure type of the AIOT channel.

[0117] In this embodiment, the first device determines whether the AIoT channel includes the first channel or the second channel based on the first information.

[0133] In this implementation, when the AIoT channel includes a first channel and a second channel, the first device determines the time-domain interval between the first channel and the second channel based on the second pre-configuration information or the first scheduling information, so that when the first device is an information sender, it can send target information according to the time-domain interval between the first channel and the second channel; when the first device is an information receiver, it can receive target information based on the determined time-domain interval between the first channel and the second channel.

[0134] Optionally, when the AIoT channel includes a first channel and a second channel, the information carried by the first channel does not repeat the information carried by the second channel.

[0141] Among them, the third pre-configuration information may include the time-domain position information or the frequency-domain position information of the AIoT channel. For example, the network may pre-configure the time-domain position or the frequency-domain position of the AIoT channel.

For example, the protocol may pre-define the time-domain position or the frequency-domain position of the AIoT channel.

[0145] In addition, for different AIoT channel carrying information types, the time-domain position or the frequency-domain position of the AIoT channel may be different. For example, for the system message and the first type of information, the AIoT device may determine the time-domain and frequency-domain position information of the AIoT channel according to the third pre-configuration information or the protocol pre-defined information; for the second type of information, the AIoT device may determine the time-domain position information or the frequency-domain position information of the AIoT channel according to the second scheduling information.

[0146] In one implementation, the system message at least includes the AIoT system basic configuration information periodically sent by the base station or the reader or the reader.

[0147] In one implementation, the first type of information at least includes signaling such as AIoT function downlink or uplink triggering or starting (summarized as the first type of signaling). The first type of signaling is mainly used for a base station, a reader, or an AIoT device to trigger or start an AIoT function process, data transmission, etc. For example, signaling for triggering an inventory function, triggering data reading, etc. The first type of information may also include data actively sent by an AIoT device (DOA data).

[0148] In one implementation, the second type of information at least includes AIoT function downlink or uplink intermediate process or response signaling (summarized as the second type of signaling). The second type of signaling is mainly used for a base station, a reader, or an AIoT device to respond to the triggering or starting signaling included in the first type of information, or intermediate process signaling triggered or started by the first type of signaling. For example, responding to signaling for triggering an inventory function, triggering data reading, or intermediate process signaling for an inventory function, triggering data reading, etc. The second type of signaling depends on the sending of a previous signaling (the previous signaling includes the first type of signaling and the second type of signaling). The second type of information also includes data transmission triggered by the first type of information or the second type of information (such as DO-DTT data, or DT data).

[0149] It should be noted that for the sending end and receiving end of the target information, the method for determining the time-domain position information or frequency-domain position information of the AIoT channel may be the same. For example, the sending end of the target information determines the time-domain position information or frequency-domain position information of the AIoT channel based on the information type carried by the AIoT channel; then, at the receiving end of the target information, the time-domain position information or frequency-domain position information of the AIoT channel can be determined based on the information type carried by the AIoT channel.

[0150] In this implementation, the first device determines the time-domain position information or frequency-domain position information of the AIoT channel based on the second information. Thus, when the first device is the information sending end, it can send the target information according to the time-domain position information or frequency-domain position information of the AIoT channel; when the first device is the information receiving end, it can receive the target information based on the determined time-domain position information or frequency-domain position information of the AIoT channel.

[0151] Optionally, the first device determines the time-domain position information or frequency-domain position information of the AIoT channel based on the second information, including at least one of the following

[0152] When the information carried by the AIoT channel is the second type of information, the first device determines the time-domain position information or frequency-domain position information of the AIoT channel based on the second scheduling information;

[0153] When the information carried on the AIoT channel is the system message or the first type of information, the first device determines the time-domain position information or frequency-domain position information of the AIoT channel based on the third pre-configured information or the protocol pre-defined information, and the type of information carried on the AIoT channel.

[0154] Among them, for the system message, the time-domain position or frequency-domain position of an AIoT channel carrying the system message can be uniquely determined according to the time-domain position information or frequency-domain position information in the third pre-configured information or the protocol pre-defined information; or multiple time-domain positions or frequency-domain positions can be determined according to the time-domain position information or frequency-domain position information in the third pre-configured information or the protocol pre-defined information, and a time-domain position and a frequency-domain position of the AIoT channel carrying the system message are determined by blind detection in the time domain and frequency domain respectively.

[0155] In addition, for the first type of information, preliminary time-domain and frequency-domain synchronization can be performed before receiving or sending the first type of information, such as time-domain and frequency-domain synchronization based on the received system message. The AIoT channel carrying the first type of information can be determined according to the time-domain position information or frequency-domain position information in the third pre-configured information or the protocol pre-defined information.

[0156] In addition, for the second type of information, the first device has received the preamble signaling (including the signaling included in the first type of information and the signaling included in the second type of information) before receiving or sending the second type of information, and the preamble signaling includes scheduling information (i.e., the second scheduling information) for the AIoT channel carrying the second type of information. The scheduling information of the AIoT channel of the second type of information can indicate the time-domain position information or frequency-domain position information of the AIoT channel.

[0157] Optionally, the AIoT channel includes a first channel and a second channel, and there is no time-domain interval between the first channel and the second channel; or

[0158] The AIoT channel includes a first channel and a second channel, and the time-domain interval between the first channel and the second channel is greater than 0; or

[0159] The AIoT channel includes a first channel; or

[0160] The AIoT channel includes a second channel.

[0161] In one implementation, the AIoT channel may only include the first channel.

[0162] In one implementation, the AIoT channel may only include the second channel.

[0163] In one implementation, the AIoT channel structure may include a total of four types:

[0164] The first type: The AIoT channel includes a first channel and a second channel, and there is no time-domain interval between the first channel and the second channel;

[0165] The second type: The AIoT channel includes a first channel and a second channel, and the time-domain interval between the first channel and the second channel is greater than 0;

[0166] The third type: The AIoT channel only includes the first channel;

[0167] The fourth type: The AIoT channel only includes the second channel.

[0168] In one implementation, the type of the AIoT channel structure can be determined based on at least one of the following:

[0169] The preamble sequence in the AIoT channel; the AIoT channel transmission type; the AIoT channel transmission resource location; the AIoT channel carried information type; the first indication information carried by the AIoT channel; the first pre-configuration information; the AIoT device type.

[0170] Optionally, the information carried by the first channel includes information that can be parsed at the first protocol layer; or, the information carried by the second channel includes information that can be parsed at the second protocol layer;

[0171] Wherein, the first protocol layer is the physical layer, and the second protocol layer is a protocol layer above the physical layer.

[0172] The embodiments of the present application are directed to a new 3GPP Internet of Things technology (referred to as: Ambient IoT, A-IoT), which is suitable for deployment in 3GPP systems. This technology is applicable to ultra-low-end Internet of Things applications. The participating A-IoT devices are ultra-low complexity and ultra-low power consumption terminals. The capabilities of such devices are different from those of existing 3GPP terminals. The existing 3GPP uplink and downlink channel designs cannot be directly applied to A-IoT devices. The embodiments of the present application provide a channel design applicable to AIoT uplink and downlink transmissions, and this problem can be solved through the embodiments of the present application.

[0173] The information transmission method provided by the embodiments of the present application is described below through several specific embodiments:

[0174] Embodiment 1:

[0175] In this embodiment, the type of the AIoT channel is described.

[0176] Exemplarily, as Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the AIoT channel structure includes a total of four types.

[0177] In one implementation, the channel structure type can be determined by the preamble sequence:

[0178] The first channel and the second channel may start with a preamble sequence, which can provide a time synchronization function or carry information. The information carried includes at least channel indication information. For example, different preamble sequences can be used for the first channel and the second channel to distinguish them, or whether there is a preamble sequence to distinguish them. The first channel can also use different preamble sequences to distinguish whether the AIoT channel includes the second channel after the first channel, or the time domain interval between the first channel and the second channel.

[0179] Optionally, the preamble sequence can include multiple sub-parts. For example, the preamble sequence includes a first synchronization sequence and a second synchronization sequence. Among them, the reception complexity of the first synchronization sequence can be lower than that of the second synchronization sequence. For example, the first synchronization sequence uses an On-Off Keying (OOK) waveform with a low chip rate, or Pulse interval encoding (PIE).

[0180] In one implementation, the channel structure type can be determined by the AIoT channel transmission type:

[0181] The AIoT channel transmission type includes uplink transmission and downlink transmission.

[0182] For uplink transmission, a specific channel structure type is adopted. In one implementation method, for uplink transmission, at least one of channel structures one, three, and four is adopted, such as Figure 3 , Figure 5 and Figure 6 as shown.

[0183] For downlink transmission, a specific channel structure type is adopted. In one implementation method, for downlink transmission, at least one of channel structures one, two, and three is adopted, such as Figure 3 , Figure 4 and Figure 5 as shown.

[0184] In one implementation, the channel structure type can be determined by the AIoT channel transmission resource location:

[0185] The network pre-configures a set of time-frequency resource locations. In this set of time-frequency resource locations, the base station, or the reader-writer, or the reader, or the AIoT device transmits using a specific channel structure type.

[0186] In one implementation, the channel structure type can be determined by the AIoT channel carried information type:

[0187] For an AIoT channel carrying a specific signaling type, a specific channel structure type is adopted:

[0188] System messages, at least including the basic configuration information of the AIoT system periodically sent by the base station, reader or interrogator. In one implementation method, the AIoT channel carrying system information adopts at least one of channel structures one, three, or four;

[0189] Type I information, at least including signaling such as AIoT function downlink or uplink triggering or starting (summarized as Type I signaling). This signaling type is mainly used by the base station, reader or interrogator or AIoT device to trigger or start the AIoT function process, data transmission, etc., such as signaling for triggering the inventory function, triggering data reading. If the AIoT channel is an uplink channel, Type I information can also include data actively sent by the AIoT device (such as DOA data). In one implementation method, the AIoT channel carrying Type I information can adopt at least one of channel structures one, two, and three;

[0190] Type II information, at least including signaling for the middle process or response of the AIoT function downlink or uplink (summarized as Type II signaling). This signaling type is mainly used by the base station, reader or interrogator or AIoT device to respond to Type I signaling. This signaling type depends on the sending of previous signaling (including Type I signaling and Type II signaling). Type II information also includes data transmission triggered by Type I information or Type II information (such as DO-DTT data or DT data). In one implementation method, the AIoT channel carrying Type II signaling can adopt at least one of channel structures three or four. Optionally, the AIoT channel carrying Type II signaling can also adopt channel structure one.

[0191] In one implementation, the channel structure type can be determined by the first channel indication:

[0192] The first channel indicates whether it includes the second channel through the payload part, and can also indicate the time interval between the first channel and the second channel through the payload part, that is, indicate one of channel structures one, two, and three through the first channel.

[0193] In one implementation, the channel structure type can be pre-configured by the network:

[0194] The network pre-configures the time interval between the first channel and the second channel to determine one of channel structures one and two.

[0195] In one implementation, the channel structure type can be determined by the AIoT device type:

[0196] Specific AIoT device types adopt specific channel structure types. In one implementation method, AIoT device type C adopts at least one of channel structure types one, two, three, and four. AIoT device types A and B adopt at least one of channel structure types one, three, and four.

[0197] Embodiment 2:

[0199] For structure type one:

[0200] As Figure 3 shown, the AIoT channel includes a first channel and a second channel, and there is no time-domain interval between the first channel and the second channel:

[0209] In the above embodiments, the information carried by the first channel includes physical layer information that can be parsed at the physical layer (PHY), and the information carried by the second channel includes MAC information or RRC information parsed at the medium access control (MAC) layer or radio resource control (RRC) layer, respectively, or information parsed at a higher layer, such as the application layer.

[0210] For structure type two:

[0211] Such as Figure 4As shown, the AIoT channel includes a first channel and a second channel. The time-domain interval between the first channel and the second channel is not zero. This time-domain interval can be the only one pre-configured by the network node or predefined by the protocol, or a set of time-domain intervals. When it is a set, one of the time-domain intervals can be indicated by the preamble sequence of the first channel, or one of the time-domain intervals can be indicated by the time-domain resource information in the downlink or uplink transmission-related information carried in the payload part of the first channel.

[0212] For the part other than the time-domain interval, Structure Type 2 can be implemented with reference to the embodiment of Structure Type 1.

[0244] For system messages, the AIoT device performs blind detection in the time domain based on the only frequency domain position information predefined by the protocol to determine a time domain position of the AIoT channel carrying the system message, and further determines other resource positions according to the period predefined by the protocol. Or the AIoT device performs blind detection in the time domain and frequency domain respectively based on multiple frequency domain positions predefined by the protocol to determine a time domain and frequency domain position of the AIoT channel carrying the system message, and further determines other resource positions according to the period predefined by the protocol.

[0245] For the first type of information, in one embodiment, the AIoT device has performed preliminary time-frequency synchronization before receiving or sending the first type of information.

[0246] In one embodiment, before receiving or sending the first type of information, the AIoT device does not perform preliminary time-domain and frequency-domain synchronization. At this time, the method for determining the time-domain and frequency-domain resource position information is the same as that of the system message.

[0247] For the second type of information, the AIoT device determines the time-domain and frequency-domain position information of the AIoT channel according to the indication of the scheduling information.

The preamble signaling includes the scheduling information of the AIoT channel carrying the second type of information.

[0249] In one embodiment, the time-domain information indicated by the scheduling information of the AIoT channel of the second type of information includes a time-domain offset and a set of time-domain resource positions. The AIoT device selects one of the set of time-domain resource positions as the time-domain resource position after receiving a time-domain offset of the preamble signaling.
