[0039] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0040] 1: A-IoT device type

[0041] In the related technologies of A-IoT research, ambient IoT devices are characterized by their energy storage capacity and their ability to generate radio frequency signals for transmission. The A-IoT device has one of the following energy storage capabilities:

[0042] Storage capacity 1: No ability to store energy;

[0043] Storage capacity 2: Energy can be stored up to E1 or E2 joules, where it is possible for E1 = E2;

[0044] Storage capacity3: Energy can be stored up to E2 joules.

[0045] Relying on these storage capacities, the related technology considers the following set of ambient IoT devices:

[0046] Device A: No energy storage, no independent signal generation / amplification, i.e. backscatter transmission;

[0047] Device B: has energy storage but no independent signal generation, i.e. backscatter transmission, where the use of stored energy may include amplification of the reflected signal;

[0048] Device C: has energy storage and independent signal generation, i.e., active RF components for transmission.

[0049] Devices with different energy storage capacities also affect their transmission quality. Generally, devices with higher energy storage also have higher receive sensitivity or higher transmit power, which means that the reliability of the receive or transmit link can be better guaranteed.

[0050] 2: AIOT business types

[0051] Main data or business types of A-IoT:

[0052] DO: Device-originated;

[0053] DT: Device-terminated;

[0054] DO traffic includes DO autonomous (DO-A) and DO device-terminated triggered (DO-DTT).

[0055] DO and DT data represent data flows originating from or being transmitted to A-IoT devices (similar to Radio Frequency Identification (RFID) tags). Data flows originating from A-IoT devices, i.e., DO data, can be further categorized as follows:

[0056] DO-A, where AIoT devices autonomously initiate data transmission, for example, by connecting to a large number of various sensors that collect and, when necessary, proactively report information about the environment, devices, and organisms;

[0057] DO-DTT refers to data transmission initiated by an AIoT device triggered by a reader / writer device such as a base station. For example, asset identification, status reporting, and tracking are all DL-triggered reports, where the reader collects data from the tag by triggering an inventory process. Because the data is generated or initiated by the IoT device, this service should be considered a DO service initiated by the tag, triggered by a reader-side control command.

[0058] 3: Control Information Reception in 3GPP NR System

[0059] In the 3rd Generation Partnership Project (3GPP) NR system, base stations can transmit physical layer downlink control information (DCI), which is carried over the physical downlink control channel (PDCCH). DCI has multiple uses, including scheduling the physical downlink shared channel (PDSCH), scheduling the physical uplink shared channel (PUSCH), scheduling the physical uplink control channel (PUCCH), triggering the uplink physical random access channel (PRACH), and transmitting 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 and downlink configuration, and cell dormancy. DCI has multiple formats, corresponding to different uses. Each format can have the same or different DCI sizes; the DCI size is unique to a given format.

[0060] To reduce the burden of blind detection on user equipment (UE) due to multiple DCI sizes (especially the complexity of channel decoding), UEs are limited to supporting a maximum of four different DCI sizes. Base stations must consider this limitation when configuring multiple DCI formats and ensure that this limit is not exceeded through configuration or size alignment according to predefined rules. For multiple DCI formats with the same size, an identifier is typically included in the DCI payload to distinguish the DCI format.

[0061] To ensure that PDCCH can achieve target performance in different channel environments, PDCCH supports multiple aggregation levels (AL), such as AL = 1, 2, 4, and 8, and supports different repetition times. In addition, to reduce PDCCH blocking between different UEs, a PDCCH has multiple candidate locations, allowing the base station to flexibly select an appropriate location to send the PDCCH.

[0062] Due to the existence of multiple ALs, multiple repetition times, and multiple candidate locations, the UE needs to perform blind detection. To control the complexity of PDCCH blind detection, the protocol defines a maximum number of PDCCH blind detections.

[0063] The information transmission method, apparatus, and related equipment provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0064] Referring to FIG. 2 , FIG. 2 is a flow chart of an information transmission method provided in an embodiment of the present application. As shown in FIG. 2 , the information transmission method includes the following steps:

[0100] In one implementation, the second channel includes a payload portion, and the start of the second channel may also include a preamble sequence to provide a time synchronization function or carry information.

[0101] It should be noted that compared with 3GPP terminals, AIOT devices have significantly lower power consumption levels and equipment complexity levels, resulting in different capabilities between AIOT devices and 3GPP terminals.

The third pre-configuration information may be information pre-configured by the network.

[0142] The third pre-configuration information may include the time domain location information or frequency domain location information of the AIOT channel. For example, the network may pre-configure the time domain location or frequency domain location of the AIOT channel. Alternatively, the protocol pre-defined information may include the time domain location information or frequency domain location information of the AIOT channel. For example, the protocol may pre-define the time domain location or frequency domain location of the AIOT channel. Alternatively, the second scheduling information may include the time domain location information or frequency domain location information of the AIOT channel. For example, the downlink transmission related information or uplink transmission related information may indicate the time domain location or frequency domain location of the AIOT channel.

The first category of information may also include data proactively sent by the AIOT device (DOA data).

[0149] In one embodiment, the second type of information at least includes an AIOT function downlink or uplink intermediate process or response signaling (generally referred to as the second type of signaling). The second type of signaling is mainly used by the base station or reader or AIOT device to respond to the trigger or start signaling contained in the first type of information, or the intermediate process signaling triggered or started by the first type of signaling, such as responding to the triggering of the inventory function, triggering the signaling of data reading, or the inventory function, triggering the intermediate process signaling of data reading. The second type of signaling depends on the sending of the preamble signaling (the preamble 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).

[0150] It should be noted that the method for determining the time domain location information or frequency domain location information of the AIOT channel can be the same for both the transmitter and receiver of the target information. For example, the transmitter of the target information can determine the time domain location information or frequency domain location information of the AIOT channel based on the type of information carried by the AIOT channel; then, the receiver of the target information can determine the time domain location information or frequency domain location information of the AIOT channel based on the type of information carried by the AIOT channel.

[0151] In this embodiment, the first device determines the time domain position information or frequency domain position information of the AIOT channel based on the second information, so that when the first device acts as an information sending end, it can send target information according to the time domain position information or frequency domain position information of the AIOT channel; when the first device acts as an information receiving end, it can receive target information based on the determined time domain position information or frequency domain position information of the AIOT channel.

[0152] Optionally, the first device determines the time domain location information or frequency domain location information of the AIOT channel based on the second information, including at least one of the following:

[0153] When the information carried by the AIOT channel is the second type of information, the first device determines the time domain position information or the frequency domain position information of the AIOT channel based on the second scheduling information;

[0154] When the information carried by the AIOT channel is the system message or the first category of information, the first device determines the time domain position information or the frequency domain position information of the AIOT channel based on the third pre-configuration information or the protocol predefined information, and the type of information carried by the AIOT channel.

[0155] Among them, for system messages, a time domain position or frequency domain position of the AIOT channel carrying the system message can be uniquely determined based on the time domain position information or frequency domain position information in the third pre-configuration information or the protocol pre-defined information; or multiple time domain positions or frequency domain positions can be determined based on the time domain position information or frequency domain position information in the third pre-configuration information or the protocol pre-defined information, and a time domain position and frequency domain position of the AIOT channel carrying the system message can be determined by blind detection in the time domain and frequency domain respectively.

[0156] In addition, for the first type of information, preliminary time domain and frequency domain synchronization may be performed before receiving or sending the first type of information, for example, time domain and frequency domain synchronization is performed based on a received system message. The AIOT channel carrying the first type of information may be determined based on the time domain location information or frequency domain location information in the third pre-configured information or the protocol predefined information.

[0157] In addition, for the second type of information, the first device has received preamble signaling (including signaling included in the first type of information and signaling included in the second type of information) before receiving or sending the second type of information. The preamble signaling includes scheduling information for the AIOT channel carrying the second type of information (i.e., second scheduling information). The scheduling information for the AIOT channel of the second type of information can indicate time domain location information or frequency domain location information of the AIOT channel.

[0158] 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

[0159] The AIOT channel includes a first channel and a second channel, and a time domain interval between the first channel and the second channel is greater than 0; or

[0160] The AIOT channel includes a first channel; or

[0161] The AIOT channel includes a second channel.

[0162] In one implementation, the AIOT channel may include only the first channel.

[0163] In one implementation, the AIOT channel may include only the second channel.

[0164] In one implementation, the AIOT channel structure may include four types:

[0165] Type 1: 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;

[0166] Type 2: 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;

[0167] The third type: AIOT channel only includes the first channel;

[0168] The fourth type: the AIOT channel only includes the second channel.

[0169] In one embodiment, the AIOT channel structure type may be determined based on at least one of the following:

[0170] 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.

[0171] Optionally, the information carried by the first channel includes information that can be parsed at a first protocol layer; or, the information carried by the second channel includes information that can be parsed at a second protocol layer;

[0172] The first protocol layer is a physical layer, and the second protocol layer is a protocol layer above the physical layer.

[0173] The present application embodiments address a new 3GPP IoT technology (called Ambient IoT, or A-IoT), suitable for deployment within 3GPP systems. This technology is suitable for ultra-low-end IoT applications. Participating A-IoT devices are ultra-low-complexity and ultra-low-power terminals. These devices differ in capabilities from existing 3GPP terminals, and existing 3GPP uplink and downlink channel designs cannot be directly applied to A-IoT devices. The present application embodiments address this issue by providing a channel design suitable for A-IoT uplink and downlink transmission.

[0174] The information transmission method provided by the embodiments of the present application is described below through several specific embodiments:

[0175] Example 1:

[0176] In this embodiment, the AIOT channel type is described.

[0177] For example, as shown in FIG3 , FIG4 , FIG5 and FIG6 , the AIOT channel structure includes four types.

[0178] In one implementation, the channel structure type may be determined by a preamble sequence:

[0179] The first channel and the second channel may start with a preamble sequence, which may provide a time synchronization function or carry information. The carried information may at least include channel indication information. For example, the first channel and the second channel may be distinguished by different preamble sequences or by whether there is a preamble sequence to distinguish them. The first channel may also use different preamble sequences to distinguish whether the AIOT channel contains the second channel after the first channel, or the time domain interval between the first channel and the second channel.

[0180] Optionally, the preamble sequence may include multiple sub-parts. For example, the preamble sequence includes a first synchronization sequence and a second synchronization sequence, wherein the reception complexity of the first synchronization sequence may be lower than the reception complexity of the second synchronization sequence. For example, the first synchronization sequence uses an on-off keying (OOK) waveform with a low chip rate, or uses pulse interval encoding (PIE).

[0181] In one implementation, the channel structure type may be determined by the AIOT channel transmission type:

[0182] AIOT channel transmission types include uplink transmission and downlink transmission.

[0183] Uplink transmission uses a specific channel structure type. In one implementation method, uplink transmission uses at least one of channel structures one, three, and four, as shown in FIG3 , FIG5 , and FIG6 .

[0184] Downlink transmission uses a specific channel structure type. In one implementation method, downlink transmission uses at least one of channel structures one, two, and three, as shown in Figures 3, 4, and 5.

[0185] In one embodiment, the channel structure type can be determined by the AIOT channel transmission resource location:

[0186] The network pre-configures a set of time-frequency resource locations, in which the base station or reader or AIOT device adopts a specific channel structure type for transmission.

[0187] In one embodiment, the channel structure type can be determined by the type of information carried by the AIOT channel:

[0188] For AIOT channels that carry specific signaling types, specific channel structure types are used:

[0189] System messages, including at least basic configuration information of the AIOT system periodically sent by the base station or interrogator or reader. In one implementation method, the AIOT channel carrying the system information adopts at least one of channel structures one, three, or four;

[0190] The first type of information includes at least signaling such as downlink or uplink triggering or starting of AIOT functions (summarized as first type of signaling). This type of signaling is mainly used by base stations, readers, or AIOT devices to trigger or start AIOT function processes, data transmission, etc., such as triggering inventory functions, triggering data reading, etc. If the AIOT channel is an uplink channel, the first type of information may also include data actively sent by the AIOT device (such as DOA data). In one implementation method, the AIOT channel carrying the first type of information may adopt at least one of channel structures one, two, and three;

[0191] The second type of information at least includes the downlink or uplink intermediate process or response signaling of the AIOT function (summarized as the second type of signaling). This type of signaling is mainly used for base stations or readers or readers or AIOT devices to respond to the first type of signaling. This signaling type depends on the sending of preamble signaling (including 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). In one implementation method, the AIOT channel carrying the second type of signaling can adopt at least one of channel structures three or four. Optionally, the AIOT channel carrying the second type of signaling can also adopt channel structure one.

[0192] In one implementation, the channel structure type may be determined by a first channel indication:

[0193] The first channel indicates whether it contains 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, the first channel indicates one of the channel structure types one, two, and three.

[0194] In one embodiment, the channel structure type can be pre-configured by the network:

[0195] The network preconfigures the time interval between the first channel and the second channel, and determines one of the channel structure types one and two.

[0196] In one implementation, the channel structure type may be determined by the AIOT device type:

[0197] A specific AIOT device type uses a specific channel structure type. In one implementation, AIOT device type C uses at least one of channel structure types 1, 2, 3, and 4. AIOT device types A and B use at least one of channel structure types 1, 3, and 4.

[0198] Example 2:

[0211] For structure type 2:

[0212] As shown in Figure 4, 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 0. The time domain interval can be a unique time domain interval pre-configured by the network node or pre-defined 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 first channel preamble sequence, or a time domain interval can be indicated by the time domain resource information in the downlink or uplink transmission related information carried by the first channel load part.

[0235] Example 3:

[0236] This embodiment illustrates a method for determining the time-domain and frequency-domain position information of an AIOT channel.

[0237] The time-domain and frequency-domain position information of the AIOT channel includes: the time-domain position information or the frequency-domain position information of the AIOT channel.

[0238] The time-domain and frequency-domain location information of the AIOT channel can be determined by at least one of the following:

[0239] AIOT channel carries information type; network pre-configuration or protocol pre-defined; scheduling information indication.

[0240] The AIOT channel carries at least one of the following information types:

[0241] System messages include at least the basic configuration information of the AIOT system sent periodically by the base station, reader, or reader.

[0242] The first type of information includes at least signaling related to downlink or uplink triggering or initiation of AIOT functions (first type of signaling). This type of signaling is primarily used by base stations, interrogators, or AIOT devices to trigger or initiate AIOT function processes and data transmission, such as triggering inventory functions or data reading. The first type of information may also include data proactively sent by AIOT devices (DOA data).

[0243] The second type of information includes at least the downlink or uplink intermediate process or response signaling of the AIOT function (second type of signaling). This type of signaling is mainly used by the base station, reader, or AIOT device to respond to the trigger or start signaling contained in the first type of information, or the intermediate process signaling triggered or started by the first type of signaling, such as the signaling that triggers the inventory function and triggers data reading, or the intermediate process signaling that triggers the inventory function and triggers data reading. This signaling type depends on the transmission of the preceding signaling (including the first type of signaling and the second type of signaling). The second type of information also includes data transmission (DO-DTT data, DT data) triggered by the first type of information or the second type of information.

[0244] For system messages and the first type of information, AIOT devices can determine the time and frequency domain location information of the AIOT channel based on the information type carried by the AIOT channel and the network pre-configuration or protocol pre-definition.

[0245] For system messages, the AIOT device performs blind detection in the time domain based on the only frequency domain position information pre-defined by the protocol to determine a time domain position of the AIOT channel carrying the system message, and further determines other resource positions based on the period pre-defined by the protocol, or the AIOT device performs blind detection in the time domain and frequency domain based on multiple frequency domain positions pre-defined 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 based on the period pre-defined by the protocol.

[0246] For the first type of information, in one embodiment, the AIOT device performs preliminary time-domain and frequency-domain synchronization before receiving or sending the first type of information, for example, performing time-domain and frequency-domain synchronization based on a received system message. The AIOT device receives or sends the AIOT channel carrying the first type of information based on unique resource location information pre-configured by the network or pre-defined by the protocol. The unique resource location information includes at least the starting position of the AIOT channel time-domain resource and part or all of the AIOT channel time-domain length, the time-domain repetition period, the frequency-domain resource location, and the frequency-domain resource size. The AIOT device determines unique resource location information based on multiple resource location information pre-configured by the network or pre-defined by the protocol. Each piece of resource location information includes at least the starting position of the AIOT channel time-domain resource and part or all of the AIOT channel time-domain length, the time-domain repetition period, the frequency-domain resource location, and the frequency-domain resource size.

[0247] In one embodiment, the AIOT device does not perform preliminary time domain and frequency domain synchronization before receiving or sending the first type of information. In this case, the method for determining the time domain and frequency domain resource location information is the same as that for the system message.

[0248] 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 scheduling information.

[0249] For the second type of information, the AIOT device has received preamble signaling (including signaling contained in the first type of information and signaling contained in the second type of information) before receiving or sending the second type of information. The preamble signaling includes scheduling information for the AIOT channel carrying the second type of information.

[0250] 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 locations. After receiving a time domain offset in the preamble signaling, the AIOT device selects one of the set of time domain resource locations as the time domain resource location. The frequency domain information indicated by the scheduling information of the AIOT channel of the second type of information includes a set of frequency domain resource locations, for example, corresponding to different backscatter link frequencies (BLFs).
