[0271] In some embodiments, when the downlink channel is a downlink data channel, the second AIOT device 1102 may send the first information to the first AIOT device 1101 through the downlink data channel.

[0286] In some embodiments, the second AIOT device may determine a parameter value of a parameter associated with the time domain resource used for the first transmission based on a starting position of the time domain resource used for the first transmission.

[0287] In some embodiments, the parameter associated with the time domain resource may be any of the following: a random number, or a time parameter, which is not limited in the present disclosure.

[0288] In some embodiments, the name of the transmission delay is not limited, and it can be, for example, "scheduling delay", "Scheduling delay", etc.

[0289] In some embodiments, the unit of transmission delay may be a time slot, a mini-time slot, a subframe, a millisecond, a second, etc., which is not limited in the present disclosure.

[0290] In some embodiments, the second AIOT device 1102 may determine the transmission delay according to the starting position of the time domain resource used for the first transmission and the sending time of the first information.

[0291] In some embodiments, "repetitive transmission parameters", "repetitive transmission related parameters", etc. can be replaced with each other.

[0292] In some embodiments, the repetition transmission parameter of the first information may be the number of repetition transmissions of the first information, or may be the repetition transmission duration of the first information, etc. For example, the repetition transmission parameter of the first information may be N time units, where the time unit may be a time slot, a subframe, or a time millisecond, etc., which is not limited in the present disclosure.

[0294] In some embodiments, to improve the coverage of AIOT devices, the first information may be repeatedly transmitted on time domain resources. For example, the first information may be repeatedly transmitted for R subframes, etc., which is not limited in this disclosure.

[0295] In some embodiments, the identifier of the associated AIOT device may be an identifier of the AIOT device used to characterize the time-frequency domain resources of the usage indication, which may be implemented in any manner to identify the associated AIOT device. For example, the identifier of the associated AIOT device may be the ID information of the AIOT device, etc., which is not limited in this disclosure.

[0298] In some embodiments, the first information may use 1 bit to indicate the type of the first transmission, or the first information may use any implementation form to indicate the type of the first transmission, which is not limited in the present disclosure.

[0299] In some embodiments, when the second AIOT device 1101 sends the first information to the first AIOT device 1101 through the downlink control channel, the first AIOT device 1101 may receive the first information sent by the second AIOT device 1102 through the downlink control channel.

[0300] In some embodiments, when the second AIOT device 1101 sends the first information to the first AIOT device 1101 through the downlink data channel, the first AIOT device 1101 may receive the first information sent by the second AIOT device 1102 through the downlink data channel.

[0301] In some embodiments, AIOT devices can be divided into two types. The first type of AIOT device can store energy and operate based on backscatter. For AIOT devices using backscattering, when sending data, they need an energy source (CW node) that provides continuous electromagnetic waves (CW) to provide them with electromagnetic waves for backscattering. When the AIOT device reflects the received CW, it can load the signaling / data to be transmitted onto the reflected wave and send it out. The reflected wave and the CW can be at the same frequency, or there can be a certain frequency offset. At the same time, the CW can also charge the AIOT device. After receiving the wireless signal CW, the first type of AIOT device can encode and modulate the signaling / data that the AIOT device needs to upload by activating the internal receiving processing module. As a result, the first type of AIOT device has low complexity and low power consumption, but it cannot amplify uplink or downlink signals.

[0302] The second type of AIOT device can store energy but does not rely on backscattering to operate, nor does it require CW power. Instead, it can operate using its own stored energy or battery power, that is, it can operate based on active transmission. However, this type of AIOT device can also operate based on backscattering. Specifically, this type of AIOT device can amplify uplink or downlink signals.

[0303] In some embodiments, the continuous electromagnetic wave CW generally has a constant amplitude, which is not limited in the present disclosure.

[0304] In some embodiments, the energy source of the continuous electromagnetic wave (CW node) can be a separate node, or it can be a base station or intermediate node that communicates with the AIOT device, etc., and this disclosure does not limit this.

[0305] In step S2102 , the first AIOT device 1101 determines frequency domain resources and time domain resources used for the first transmission based on the first information.

[0306] In some embodiments, when the first information includes the starting position, center frequency, and number of frequency domain resources used by the first transmission, the first AIOT device 1101 can determine the starting position and center frequency of the frequency domain resources used by the first transmission based on the first information.

[0307] In some embodiments, when the frequency of the first AIOT device 1101 after backscattering by a continuous electromagnetic wave (CW) is equal to the indicated frequency, if the center frequency of the frequency domain resource indicated in the first information is f1 and the indicated frequency domain resource is 300 kilohertz (khz), then the first AIOT device 1101 can use f1 as the center frequency and a bandwidth of 300 khz to send uplink information to the base station.

[0308] In some embodiments, when the first information does not include the starting position and center frequency of the frequency domain resource, the first AIOT device 1101 may determine the starting position of the frequency domain resource based on a blind detection result.

[0309] In some embodiments, when the first information does not include the starting position and center frequency of the frequency domain resource, the first AIOT device 1101 may also determine the center frequency of the frequency domain resource according to pre-configuration or protocol agreement.

[0310] In some embodiments, the first AIOT device 1101 can determine the center frequency of the frequency domain resources used for the first transmission based on the frequency points pre-configured by the terminal, pre-configured by the cell, or pre-configured by the device type, or can also determine the center frequency based on the protocol agreement, which is not limited in this disclosure.

[0311] In some embodiments, if the center frequency is pre-configured based on a cell (cell specific), multiple AIOT devices can use the same center frequency. The frequency domain resources of multiple AIOT devices can be the same, but the time at which different AIOT devices transmit information can be different. This disclosure does not limit this.

[0312] In some embodiments, when the first information does not include the starting position and center frequency of the frequency domain resource, the first AIOT device 1101 may also determine the center frequency of the frequency domain resource based on the center frequency of the continuous wave.

[0313] In some embodiments, the name of the continuous wave is not limited, and it can be, for example, “continuous electromagnetic wave”, “CW”, “continuous wave”, etc.

[0314] In some embodiments, when the first AIOT device 1101 determines the center frequency of the frequency domain resource based on the center frequency of the continuous wave, the center frequency of the determined frequency domain resource may be equal to the center frequency of the continuous wave, or there may be a certain offset value between the center frequency of the determined frequency domain resource and the center frequency of the continuous wave. This disclosure does not limit this.

[0315] In some embodiments, the offset value between the center frequency of the frequency domain resource and the center frequency of the continuous wave can be determined based on the AIOT device, or can be pre-configured, or can be provided by a node other than the base station and the AIOT device, etc., and this disclosure does not limit this.

[0316] In some embodiments, when the first information includes the starting position of the time domain resources used for the first transmission and the number of time domain resources, the first AIOT device 1101 may determine the starting position of the time domain resources used for the first transmission based on the first information.

[0317] In some embodiments, if the first information does not include the starting position of the time domain resources used for the first transmission, the first AIOT device 1101 can determine the starting position of the time domain resources used for the first transmission based on the reception time and transmission delay of the first information. For example, if the first AIOT device 1101 receives the first information at time n (time slot / mini-time slot / subframe) and the transmission delay indicated in the first information is k0, the first AIOT device 1101 can determine the starting position of the time domain resources to be n+k0+1.

[0318] In some embodiments, if the first information does not include the starting position of the time domain resource used for the first transmission, the first AIOT device 1101 may first determine a parameter associated with the time domain resource used for the first transmission, and then determine the starting position of the time domain resource based on the parameter. The parameter associated with the time domain resource can be any of the following: a random number or a time parameter, which is not limited in this disclosure.

[0319] In some embodiments, the first AIOT device 1101 may determine parameters associated with time domain resources according to a protocol agreement.

[0320] In some embodiments, the first AIOT device 1101 may also determine parameters associated with time domain resources according to an instruction of the first information.

[0321] In some embodiments, the first AIOT device 1101 may also determine parameters associated with time domain resources based on the configuration information.

[0322] In some embodiments, when the parameter associated with the time domain resource is a time parameter X, the first AIOT device 1101 may generate a random number based on the value of X, and then use the time when the random number is decremented to 0 as the starting position of the time domain resource when the first AIOT device 1101 performs the first transmission. The value of X may range from 0 to M, and the bit value of the information word is log2M.

[0323] In some embodiments, when the parameter associated with the time domain resource is a random number Y, the first AIOT device 1101 may use the time when the random number is decremented to 0 as the starting position of the time domain resource when the first AIOT device 1101 performs the first transmission. The value of Y may range from 0 to M, and the bit value of the information word is log2M.

[0324] In some embodiments, when the first information does not include the starting position of the time domain resources used for the first transmission, the first AIOT device 1101 may also first determine the reference time based on the wireless frame number and time slot number indicated by the first information, and then determine the starting position of the time domain resources used for the first transmission based on the reference time and the offset value of the time domain resources relative to the reference time.

[0325] In some embodiments, the first AIOT device 1101 may determine an offset value of the time domain resource relative to the reference time based on the first information.

[0326] In some embodiments, the first AIOT device 1101 may also determine an offset value of the time domain resource relative to the reference time according to a protocol agreement.

[0327] In some embodiments, the first AIOT device 1101 may also determine an offset value of the time domain resource relative to the reference time according to the configuration information.

[0328] In some embodiments, in a data inventory scenario, the first information received by the first AIOT device 1101 may further include a label of an operation applicable to the resources used in the first transmission.

[0329] In some embodiments, the label of the operation applicable to the resource may be any one of the following: a select command, a session indication, or a target label, which is not limited in the present disclosure.

[0330] In some embodiments, tags have multiple attributes. The first AIOT device 1101 can use the Select command to change certain attributes and flags based on user-defined standards and policies, manually select or circle a specific group of tags, and perform inventory identification or access operations on them. This helps reduce conflicts and repeated identification and speeds up identification.

[0331] In some embodiments, a session has four different session layers: s0, s1, s2, and s3. Each session layer has two states, A and B. By default, it is in state A. It can transition to state B after tags are counted. The differences between these four session layers lie in the state transitions.

[0332] In the Radio Frequency Identification Second Generation (RFID Gen2) protocol, session parameters facilitate tag inventory. Each tag contains four sessions, S0 to S3, each with two inventory flags, A and B. These flags are not interoperable between sessions. In other words, a tag can have both flag A (S2) and flag B (S3), allowing different readers to inventory the same tag simultaneously.

[0333] In addition, in addition to the flag bits A and B of S0 to S3, the RFID tag supporting the Gen2 protocol also has a flag bit SL (-SL) that is interoperable between various sessions. Any session can use this flag bit.

[0334] In addition, the tag can also have a flag bit, C. This flag bit has the same retention time as the tag's own response buffer, ResponseBuffer. Similarly to the flag bits in states S2 or S3, flag bit C remains for the duration and is refreshed after power is turned on. (C: After power is turned off, the data in ResponseBuffer remains for 0 to 5 seconds. The retention time of flag bit C is the same as the retention time of flag bit C.)

[0335] In some embodiments, the target tag can be used to indicate two inventoried flags, A and B.

[0336] In step S2103 , the first AIOT device 1101 performs a first transmission.

[0337] In some embodiments, after receiving the first information, the first AIOT device may determine the time-frequency domain resources for the first transmission based on the first information, and then perform the first transmission based on the determined time-frequency domain resources used for the first transmission.

[0595] For a detailed description of step S4301, please refer to the above embodiment description.

[0596] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0597] In this embodiment, the second AIOT device can indicate the associated information of the first transmission by sending the first information to the first AIOT device, thereby improving resource utilization and improving the efficiency of the AIOT system.

[0598] The following is an exemplary introduction to the above method.

[0599] The present disclosure is used to improve the resource utilization of the AIOT system to a certain extent by indicating the associated information of the first transmission to the passive AIOT device. The optional implementation scheme is as follows:

[0600] The present disclosure relates to a communication method. Taking the second AIOT device as a base station as an example, the method includes:

[0601] The base station sends the first information (downlink information), which can be used to instruct (schedule) the uplink transmission of the AIOT device. The first information sent by the base station can contain at least one or more of the following information: The first information can be control information, or it can be command information sent by the base station that requires the AIOT device to respond, etc.

[0602] 1. The frequency resource assignment information field can be used as follows:

[0603] Option 1: Indicates the center frequency f of the frequency domain resources used and the number of frequency domain resources.

[0604] Indicates the number of frequency domain resources, which can indicate the number of used subcarriers / PRBs / subchannels / frequency domain resource units / communication bandwidths.

[0605] Indicates the center frequency f1 of the frequency domain resource.

[0606] For example, if the indicated center frequency is f1 and the indicated frequency domain resource is 300 kHz, the AIOT device can send uplink information to the base station with f1 as the center frequency and a bandwidth of 300 kHz (this scenario requires that the frequency of the AIOT device after backscattering is equal to the indicated f1).

[0607] Option 2: Indicates the number of frequency domain resources used.

[0608] Indicates the number of frequency domain resources, which can indicate the number of used subcarriers / PRBs / subchannels / frequency domain resource units / communication bandwidths.

[0609] The starting position or center frequency of the frequency domain resource is determined as follows:

[0610] (1) Based on blind detection, information can be sent to the base station according to the starting position of the frequency domain resources and the number of resources indicated determined by the blind detection.

[0611] (2) The center frequency f1 of the frequency domain resource can be pre-configured by the base station based on the terminal (User Equipment, UE) / cell / device type, or can be pre-defined based on the protocol. The AIOT device uses f1 as the center frequency and sends uplink information to the base station using the indicated frequency domain resource (if the center frequency f1 is pre-configured based on the cell, multiple AIOT devices will use the same center frequency. The frequency domain resources of multiple AIOT devices can be overlapping, but the transmission time of different devices can be different, so in this case, no conflict will occur).

[0612] (3) The center frequency f1 of the frequency domain resource can be determined based on the frequency fc of the continuous electromagnetic wave (CW). The relationship between the center frequency f1 and the frequency fc of the CW can be that f1 is equal to fc, or there can be a certain offset between f1 and fc. All AIOT devices can use different f (the center frequency fc of the CW can be determined based on the center frequency of the downlink information received from the base station, or it can be a CW provided by other nodes other than the base station and the AIOT device, and the frequency fc of the CW can be preconfigured and predefined).

[0613] This frequency value and the CW frequency value may be different.

[0614] 2. Indicate time resource assignment, which can be done in the following ways:

[0615] Option 1: Indicates the starting position of the time domain resources (such as time slots / mini-time slots / subframes) used and the number of time domain resources.

[0616] The starting position of the time domain resource may be a time offset value relative to a reference time. For example, if the offset value range is pre-configured to be 0-M, the starting position of the time domain resource may be represented by log2(M).

[0617] The number of time domain resources may indicate the number of consecutive time slots / mini-time slots / subframes, or indicate the consecutive time length in milliseconds, seconds, etc. For example, if the number of time slots indicated by the pre-configuration is M, log2(M) bits are used to indicate it.

[0618] In particular, the number of time domain resources is fixed at 1. For example, an uplink transmission of an AIOT device can only occupy 1 time slot, 1 micro-slot / subframe, 1ms, etc.

[0619] Option 2: Only indicates the number of time domain resources used.

[0620] The number of time domain resources can indicate the number of consecutive time slots / mini-time slots / subframes, or indicate the consecutive time length in milliseconds, seconds, etc. For example, if the number of time slots indicated in the pre-configuration is M, log2(M) bits are used to indicate it (the same method as the indication of the number of time domain resources in Option 1).

[0621] In particular, the number of time domain resources is fixed at 1. For example, an uplink transmission of an AIOT device can only occupy 1 time slot, 1 micro-slot / subframe, 1ms, etc.

[0622] The starting position of the time domain resource can also be determined by implicit indication or implicit determination:

[0623] The AIOT device combines the scheduling delay information field to determine the time when the AIOT device starts sending (the starting position of the time domain resource).

[0624] For example, if the first message is received at time n (time slot / mini-time slot / subframe), and the scheduling delay indicated by the scheduling delay carried in the first message is k0, the AIOT device will start sending uplink information to the base station at time n+k0+1.

[0625] Option 3: Indicates a parameter X related to the time domain resource, and determines the time domain resource to be used according to a certain rule based on the parameter.

[0626] Indicates the value of the time parameter X. A random number is generated based on this value. The time when the random number reaches 0 is used as the response time. The AIOT device sends information to the base station at this response time. The value of X ranges from 0 to M. The bit value of this information field is log2(M).

[0627] Indicates a random number Y. The time when the random number decreases to 0 is used as the response time. During this response time, the AIOT device sends information to the base station. The value of Y ranges from 0 to M. The bit value of this information field is log2(M).

[0628] 3. Scheduling delay, indicating the uplink scheduling delay.

[0629] The scheduling delay unit can be time slot, mini-time slot, subframe, millisecond, second, etc.

[0630] If downlink control information is received at time n (subframe) and the indicated scheduling delay is k0, the AIOT device will send uplink information to the base station after time n+k0+1.

[0631] 4. Reference time: indicates a reference time based on which the starting position of the time domain resources to be used is determined.

[0632] The reference time unit can be a time slot, a mini-time slot, a subframe, a millisecond, a second, etc.

[0633] Embodiment 1: The reference time may be jointly indicated by a radio subframe number and a time slot number, that is, indicating in which radio frame and which time slot the reference time is located in the radio frame.

[0634] For example, 10 bits are used to indicate the radio frame number (the maximum value of the radio frame number is 1024 frames), and Y=log2b is used to indicate the time slot number in the radio frame, where b indicates that one radio frame has b time slots.

[0635] 5. Group information or AIOT device ID information, indicating a scheduled AIOT device group, or indicating a scheduled AIOT device.

[0636] 6.1 bit indicates whether the first information is used for uplink scheduling or downlink scheduling.

[0637] 7. Modulation and Coding Scheme (MCS), which indicates the modulation and coding scheme used for uplink information sent by the AIOT device to the base station.

[0638] 8. The repetition transmission parameter may indicate the number of uplink repetition transmissions or the duration of uplink repetition transmissions.

[0639] The AIOT device ultimately determines the uplink continuous transmission time N, where N = the number of uplink repeated transmissions × the amount of allocated uplink time resources. The unit of N can be time slots, mini-slots, subframes, milliseconds, seconds, etc.

[0640] If the indicated time domain resource is transmitted on two consecutive time slots and the indicated number of repeated transmissions is 2, the AIOT device repeats the transmission on 2×2=4 consecutive time domain resources.

[0641] 9. Downlink repetition transmission parameter, used to indicate the number of repetition transmissions of the first information, or the repetition transmission duration.

[0642] For example, the first information is instructed to be repeatedly sent for R subframes (repeated transmission in the time domain can improve the coverage of AIOT devices).

[0643] 10. Uplink retransmission parameter, used to indicate the number of retransmissions or the duration of retransmissions in the uplink time domain sent by the AIOT device.

[0644] For example, if the indicated time domain resource is 1 time slot, the determined starting position of the time domain resource is slot x, and the uplink is repeated twice, then the AIOT device will send the uplink information on the time domain resource slot x, slot x+1.

[0645] 11. Parameters or commands related to the inventory device, such as the select command, session indication, and target tag status indication (this information field is carried in the inventory scenario, but not in the perception scenario).

[0646] Furthermore, the first information is sent on a downlink channel. The downlink channel of the AIOT system may have the following situations:

[0647] Case 1: Design control and data channels for downlink transmission in an AIOT system. The control channel can carry uplink or downlink scheduling information, while the data channel can be used to send downlink data or paging.

[0648] Case 2: Only one channel is defined for downlink transmission of the AIOT system. Multiple transmission formats can be used on this channel. Different formats are used to send different information. For example, format 1 is used to send uplink scheduling information, format 2 is used to send downlink scheduling information, format 3 is used to send downlink data, and format 4 is used to send commands that require a response from the AIOT device.

[0649] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., a RAN) in any of the above methods.

[0650] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD).

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0651] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and implementing the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
