[0132] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0133] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0134] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0135] To enable those skilled in the art to better understand the embodiments of the present disclosure, the following description is first given:

[0136] 1. A-IoT devices

[0137] 1) A-IoT devices include three types of devices (Device Type), including whether they have energy storage capabilities and independent signal transmission capabilities:

[0138] Device A: No energy storage capability, no independent signal generation capability, and transmits signals via backscattering.

[0139] Device B: It has energy storage capability but no independent signal generation capability. It transmits signals via backscattering, and the stored energy can be used to amplify the power of the backscattered signal.

[0140] Device C: has energy storage capabilities, the ability to independently generate signals, and uses radio frequency devices for signal transmission.

[0141] 2) Backscatter communication

[0142] A backscatter communication system consists of an excitation signal source and a signal reflection device, typically consisting of a reader and a reflective tag. The reader generates the RF excitation signal, while the reflective tag is a device that reflects RF signals. The reader transmits an RF signal to the reflective tag, which receives the signal from the excitation signal source and reflects the RF signal back to the tag. By varying the load impedance of the reflective tag antenna, information is modulated into the backscatter signal. When the reflection coefficient is configured to the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured to the second reflection coefficient, the excitation signal is completely reflected; and when the reflection coefficient is configured to the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0143] 2. A-IoT Network Topology

[0144] In Topology 1, as shown in Figure 1, A-IoT devices communicate directly with a base station in two directions. Communication between the base station and the A-IoT device includes ring A-IoT data and / or signaling. In this topology, the base station (BS) sent to the A-IoT device may be different from the BS received from the A-IoT device.

[0145] In Topology 2, as shown in Figure 2, A-IoT devices communicate bidirectionally with intermediate nodes between the devices and the base station. In this topology, intermediate nodes can be A-IoT-enabled relays, Integrated Access Backhaul (IAB) nodes, User Equipment (UE), repeaters, and more. Intermediate nodes transmit A-IoT data and / or signaling between the base station and the A-IoT devices.

[0146] 3. On-Off Keying (OOK) Waveform Signal Based on Orthogonal Frequency Division Multiplexing (OFDM) Technology

[0147] The OFDM-based OOK waveform can reuse the basic architecture of the NR base station transmitter, while the receiver only performs envelope detection based on the OOK waveform, simplifying the receiver's complexity and reducing receiver power consumption. The following uses OOK-1 and OOK-4 as examples to introduce:

[0148] OOK-1: One OFDM symbol corresponds to a single-bit OOK signal.

[0150] OOK=1 means that all SCs are used for modulation, corresponding to bit "1", or any one or several corresponding bits of K-order modulation symbols are "1";

[0151] OOK=0 means that all SCs are zero power (from the baseband perspective), corresponding to bit "0", or any one or several corresponding bits "0" of the K-order modulation symbols.

[0152] OOK-4: Time-domain M-bit OOK, one OFDM symbol corresponds to an M-bit OOK signal.

[0153] The N SCs of OOK-4 are generated by transform (DFT / least squares):

[0154] N' samples are generated from M bits;

[0155] Signal modulation may or may not be used;

[0156] Truncation or other additional modulation may or may not be used, in which case N is the same as N'.

[0157] 4. OFDM symbol generation method in NR:

[0158] For any physical channel or signal other than the Physical Random Access Channel (PRACH), the time-continuous signal OFDM symbol in antenna port p and subframe The subcarrier spacing configuration μ is defined as:

[0159] If t=0, at the beginning of the subframe,

[0160] as well as

[0161] κ = 64; Δf =2 μ ·15[kHz]; μ is the subcarrier spacing configuration; μ0 is the maximum μ value between the subcarrier spacing configurations of the SCS specific carrier list of each of the uplink and downlink and the SCS specific carrier list of the sidelink.

[0162] in is the start time of the next OFDM symbol in the subcarrier spacing configuration μ, is the length of the OFDM symbol with subcarrier spacing configuration μ.

[0163] Tc is the time unit in NR system, is the OFDM symbol length without CP, is the length of CP. is the number of symbols in a time slot, The number of time slots in the next subframe is configured for the subcarrier spacing μ.

[0164] The frequency domain starting position under carrier spacing configuration μ is The size of the frequency domain resources occupied by the carrier spacing configuration μ, Indicates the number of subcarriers in an RB.

[0165] For the OFDM symbol part:

[0166] For the Cyclic Prefix (CP) part:

[0179] Preamble sequence, mid-band sequence, control information, data information, start identifier, end identifier, delimiter, processing delay, anti-inter-symbol interference, time interval, synchronization information.

[0180] The time interval GAP is the time interval between the first signal and / or related information of the first signal and the alignment boundary in the M third resource units. The first device may not receive or send data during this time interval, or the device may store energy based on the energy of the received signal.

[0181] In some embodiments, the time domain resource information includes at least one of the following:

[0182] The boundaries of K first time domain resource units are aligned with the boundaries of M third time domain resource units, or the boundaries of L second time domain resource units are aligned with the boundaries of M third time domain resource units, or the boundaries of K first time domain resource units and L second time domain resource units are aligned with the boundaries of M third time domain resource units; wherein K and L are respectively integers greater than or equal to 0, and M is an integer greater than or equal to 1;

[0183] a method for processing a cyclic prefix CP in the third time domain resource unit;

[0184] A positional relationship between the first time domain resource unit and the second time domain resource unit;

[0185] The third time domain resource unit is a time domain resource unit for a third device to receive or send a second signal, and the second signal is an air interface signal.

[0186] That is to say, the first device can obtain at least one of the above contents by acquiring the time domain resource information.

[0187] Among them, the boundaries of the K first time domain resource units are aligned with the boundaries of the M third time domain resource units, or the boundaries of the L second time domain resource units are aligned with the boundaries of the M third time domain resource units, or the boundaries of the K first time domain resource units and the L second time domain resource units are aligned with the boundaries of the M third time domain resource units, that is, the boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of the M third time domain resource units, which can also be understood as the alignment method of the first signal and / or the related information of the first signal with the second signal, that is, the frame format of the first signal and / or the related information of the first signal. By aligning the boundaries of the time domain resource units, the coexistence of the first signal and the air interface signal is achieved, and the mutual interference between the two types of signals is reduced.

[0188] Among them, the processing method of the CP in the third time domain resource unit includes: using all or part of the CP of each OFDM symbol in the M third time domain resource units for the transmission of relevant information of the first signal. For example, the M third time domain resource units include 14 OFDM symbols, and the CP of these 14 OFDM symbols can be regarded as a CP set, and all or part of this CP set is used for the transmission of relevant information of the first signal. For another example, the M third time domain resource units include 14 OFDM symbols, of which the CP of the first 7 OFDM symbols can be regarded as a CP set, and this CP set is used for the transmission of relevant information of the first signal.

[0189] Among them, the positional relationship between the first time domain resource unit and the second time domain resource unit, that is, the relative position between the first time domain resource unit and the second time domain resource unit, for example, as shown in Figure 4, in case a, the L second time domain resource units are located at the front end of the K first time domain resource units; in case b, the L second time domain resource units are located at the rear end of the K first time domain resource units; in case c, the L1 second time domain resource units in L are located at the front end of the K first time domain resource units, and the L2 second time domain resource units in L are located at the rear end of the K first time domain resource units; in case d, the second time domain resource unit is located at a specific position of the K first time domain resource units.

[0190] Of course, in addition to the above content, the first device can also obtain other information through time domain resource information, such as the type of the first signal, the waveform of the first signal, the waveform generation related parameters of the first signal, etc., so as to realize the reception or sending of the first signal and / or related information of the first signal.

[0191] In some embodiments, the waveform of the first signal includes at least one of a default waveform and a non-default waveform.

[0192] In some embodiments, in this embodiment, the second device or the third device includes at least one of the following:

[0193] Network-side devices, terminals, readers, external devices, etc.

[0194] As an implementation method, the second device and the third device can be the same, such as the first device receives a first signal (such as an R2D link signal) sent by a network side device such as a base station, and the boundaries of the K first time domain resource units and L second time domain resource units of the first signal are aligned with the boundaries of the M third time domain resource units of the second signal sent by the base station.

[0195] Of course, the second device and the third device may also be different. For example, the first device receives a first signal (such as an R2D link signal) sent by a reader, and the boundaries of the K first time domain resource units and the L second time domain resource units of the first signal are aligned with the boundaries of the M third time domain resource units of the second signal sent by the network side device (such as a base station).

[0196] In some embodiments, the time domain resource information includes at least one of the following:

[0197] First indication information, where the first indication information is used to indicate that boundaries of the K first time domain resource units are aligned with boundaries of the M third time domain resource units, or that boundaries of the L second time domain resource units are aligned with boundaries of the M third time domain resource units, or that boundaries of the K first time domain resource units and the L second time domain resource units are aligned with boundaries of the M third time domain resource units;

[0198] the values ​​of K, L, and / or M;

[0199] a type of the first signal;

[0200] second indication information, where the second indication information is used to indicate whether the first indication information corresponding to different types of the first signals is the same;

[0201] a waveform of the first signal;

[0202] Waveform generation related parameters of the first signal;

[0203] third indication information, where the third indication information is used to indicate a type of downlink signaling carrying the time domain resource information;

[0204] Fourth indication information, where the fourth indication information is used to indicate a processing method for the CP in the third time domain resource unit;

[0205] fifth indication information, where the fifth indication information is used to indicate a positional relationship between the first time domain resource unit and the second time domain resource unit;

[0206] Sixth indication information, where the sixth indication information is used to indicate relevant information of the first signal.

[0207] That is, the time domain resource information can inform the first device of at least one item of the above information, so that the first device can receive or send the first signal and / or related information of the first signal based on the information. For example, the first device obtains the first indication information, namely: the boundaries of the K first time domain resource units are aligned with the boundaries of the M third time domain resource units, or the boundaries of the L second time domain resource units are aligned with the boundaries of the M third time domain resource units, or the boundaries of the K first time domain resource units and the L second time domain resource units are aligned with the boundaries of the M third time domain resource units.

[0208] Among them, the types of the first signal include three types, corresponding to the signal sent or received on the link from the second device to the first device; carrier or excitation signal; signal sent or received on the link from the first device to the second device.

[0209] The waveform of the first signal may be at least one of OFDM-based OOK-1, OOK-2, OOK-3, OOK-4, ASK, FSK, PSK and other waveforms, at least one of single-carrier-based OOK-1, OOK-2, OOK-3, OOK-4, ASK, FSK, PSK and other waveforms, or at least one of multiple-carrier-based OOK-1, OOK-2, OOK-3, OOK-4, ASK, FSK, PSK and other waveforms. Of course, in the time domain resource information, the waveform of the first signal may be clearly defined as a certain waveform, or may be represented as a default waveform, and the specific default waveform is predefined or configured. The waveform of the first signal may also be specifically indicated by a downlink signal or an R2D link signal.

[0210] The waveform generation-related parameters of the first signal include, but are not limited to, the number of code elements (chips) of the OFDM-based OOK-4 waveform, that is, the number of OOK symbols corresponding to one NR OFDM symbol. Of course, in the time domain resource information, the waveform generation-related parameters of the first signal (such as the number of code elements of the OFDM-based OOK-4 waveform) can be explicitly set to a certain value or can be expressed as a default value, and the specific default value is predefined or configured.

[0211] Among them, the second indication information can indicate whether the first indication information of the first signal of the relevant type is the same through "0" or "1". For example, in the time domain resource information, the type of the first signal is "type 1 and type 2", and the second indication information is "1", then it can be known that the first indication information of the first signal of type 1 and type 2 is the same. Of course, the time domain resource information may also not include the second indication information. By indicating the first indication information of the corresponding type of first signal through the type of the first signal and the first indication information, it can also be known whether the first indication information of different types of first signals is the same. Of course, when the second indication information indicates that the first indication information of the three types of first signals is different, it can be completely different, or it can have a nested relationship or the same basic format.

[0212] The downlink signaling carrying the time domain resource information includes at least one of the following types: signaling carried by an R2D link, radio resource control (RRC) layer signaling, medium access control (MAC) layer signaling, and physical layer (PHY) signaling.

[0213] It should be noted that other information of the time domain resource information can also be expressed in an explicit or default manner. For example, the fourth indication information can clearly indicate that the processing method of the CP in the third time domain resource unit is a certain method, or it can be expressed as a default method, and the specific default method is pre-defined or configured.

[0214] It should be noted that the first device may determine at least one of the following based on the time domain resource information:

[0215] An association relationship between at least one type of first signal and a second signal, such as a boundary alignment relationship between time domain resource units of at least one A-IoT signal and an NR signal;

[0216] the number of first time domain resource units and / or second time domain resource units corresponding to the first signal;

[0217] The values ​​of K, L, and M;

[0218] The first time domain resource unit is used to receive or send data or control information of a first signal;

[0219] The second time domain resource unit is used to receive or send relevant information of the first signal;

[0220] The K first time domain resource units and / or the L second time domain resource units are at the time domain positions of the third time domain resource unit.

[0221] In some embodiments, the time domain resource information is determined by at least one of the following methods:

[0222] Pre-specified; downlink signaling indication; query signal indication; device pre-storage; synchronization or timing signal indication; preamble indication; midamble indication; postamble indication; signal indication sent or received on the link from the second device to the first device.

[0223] The pre-specified condition may be a protocol agreement. Downlink signaling indication: The second device transmits downlink signaling, which indicates the time domain resource information, such as the downlink signaling carrying the time domain resource information. Downlink signaling also includes an R2D link signal transmitted from at least one device, such as a terminal, a reader / writer, and an external device, which indicates the time domain resource information to the first device, such as the downlink signaling carrying the time domain resource information. Device pre-storage: The first device pre-stores the time domain resource information.

Midamble indication: The second device transmits a midamble, which indicates the time domain resource information, such as pre-associating different midambles with different time domain resource information. The post-amble indication refers to the second device sending a post-amble, which is used to indicate the time domain resource information, such as pre-associating different post-ambles with different time domain resource information. The query signal indication refers to the second device sending a query signal, which is used to indicate the time domain resource information, such as the query signal carrying the time domain resource information. The signal indication sent or received on the link from the second device to the first device refers to the signal sent or received on the link from the second device to the first device, which is used to indicate the time domain resource information, such as the signal sent or received on the link from the second device to the first device, which is used to indicate the time domain resource information.

[0224] In addition, in this embodiment, as an implementation method, the first device receives the R2D link signal and / or the carrier or excitation signal based on the time domain resource information. Specifically, the first device performs at least one of the following: based on the second time domain resource unit, obtains at least one of the following: a preamble sequence, a midamble sequence, control information (such as R2D link control information), data information (R2D link data information), a start identifier, an end identifier, a delimiter, a processing delay, anti-inter-symbol interference, a time interval, a synchronization information start / end position, an AIoT symbol length, a processing time after receiving the AIoT signal, and an end time; based on the first time domain resource unit, obtains relevant information of at least one of the received R2D link signal and the carrier / excitation signal, and receives at least one of the R2D link signal and the carrier / excitation signal based on the relevant information.

[0225] In this embodiment, as an implementation method, the first device sends a D2R link signal based on the time domain resource information. Specifically, the first device performs at least one of the following: based on the second time domain resource unit, obtaining at least one of a preamble sequence, a midamble sequence, control information (such as D2R link control information), data information (D2R link data information), a start identifier, an end identifier, a delimiter, a processing delay, anti-inter-symbol interference, a time interval, synchronization information (such as synchronization-related information related to the D2R link signal), timing-related information, a starting position, an AIoT symbol length, a processing time for sending the D2R link signal, and an end time; based on the first time domain resource unit, obtaining relevant information for sending the D2R link signal, and sending the D2R link signal based on the relevant information.

[0226] It should be noted that, in this embodiment, the first device sends the D2R link signal, which may be that the first device actively sends the D2R link signal, or reflects the D2R link signal.

[0227] In some embodiments, in this embodiment, the M third time domain resource units include N OFDM symbols, where N is greater than or equal to 1.

[0228] That is, N is the number of OFDM symbols included in the M third time domain resource units. Assuming M=1, the third time domain resource unit is a time slot, then N=N OFDM , N OFDM Is the number of OFDM symbols included in one time slot. For normal CP, N OFDM is 14; for extended CP, N OFDM is 12.

[0229] In some embodiments, the value of K is equal to the sum of M1 and N1;

[0230] Wherein, the M1 includes at least one of the following:

[0231] N2 times K1, where K1 is the number of first time-domain resource units corresponding to the length of an OFDM symbol not carrying a CP, N2 is an integer greater than or equal to 0, and N2 is less than or equal to N;

[0232] N3 times K2, where K2 is the number of first time-domain resource units corresponding to the length of an OFDM symbol carrying a CP, N3 is an integer greater than or equal to 0, and N3 is less than or equal to N;

[0233] the number of the first time-domain resource units;

[0234] Here, N1 is the number of the first time domain resource units, and N1 is an integer greater than or equal to 0; and N1 is less than or equal to K1, or N1 is less than or equal to K2.

[0235] Here, the value of K is divided into two parts, namely M1 and N1. In some embodiments, relevant parameters such as M1, N1, K1, K2, N2, and N3 can be obtained through protocol definition, downlink signaling indication, device pre-storage, etc.

[0236] In some embodiments, for M1, at least one of the following conditions is included:

[0237] In case 1, M1 can be N2 times K1, M1=K1*N2, that is, a length of an OFDM symbol not carrying a CP can be configured to correspond to K1 first time domain resource units. For example, in scheme 5 of FIG7 , an OFDM symbol not carrying a CP corresponds to 4 first time domain resource units, K1=4. In this way, for M third time domain resource units, M1 first time domain resource units can be determined based on the OFDM symbol not carrying a CP and K1.

[0238] Case 2: N3 times K2, M1 = K2 * N3, that is, the length of an OFDM symbol carrying a CP can be configured to correspond to K2 first time domain resource units. For example, in scheme 6 of Figure 7, the OFDM symbol carrying a CP corresponds to 4 first time domain resource units, K2 = 4. In this way, for M third time domain resource units, M1 first time domain resource units can be determined based on the OFDM symbol carrying a CP and K2;

[0239] Case 3: the number of first time domain resource units, M1=K, that is, M third time domain resource units can be configured to correspond to K first time domain resource units to determine the first time domain resource unit. At this time, N1=0.

[0240] In some embodiments, for N1, N1 is the number of the first time domain resource units, and N1 is an integer greater than or equal to 0; and N1 is less than or equal to K1, or N1 is less than or equal to K2. Case 1: N1 = K, in which case M1 = 0; Case 2: When the length of the OFDM symbol not carrying a CP is configured to correspond to K1 first time domain resource units, or the length of the OFDM symbol carrying a CP corresponds to K2 first time domain resource units, and the M third time domain resource units are not equal to an integer multiple of K1 or K2, in addition to the M1 first time domain resource units, N1 first time domain resource units can also be obtained. As shown in FIG5 , the length of the OFDM symbol not carrying a CP corresponds to K1 (K1 = 4) first time domain resource units, and the number K of the first time domain resource units is equal to K1*N2+N1=4*2+2.

[0241] In some embodiments, in this embodiment, the length of the first time domain resource unit is equal to at least one of the following:

[0242] A result of rounding up or rounding down the first length, the first length being equal to 1 / K1 of the length of an OFDM symbol not carrying a CP;

[0243] Alternatively, the result of rounding up or rounding down the second length, the second length being equal to 1 / K2 of the length of the OFDM symbol carrying the CP;

[0244] Or, a result of rounding up or rounding down 1 / K of the third length, the third length is equal to the length of the M third time domain resource units;

[0245] Or, a result of rounding up or rounding down 1 / K of a fourth length, where the fourth length is equal to the length of N2 OFDM symbols not carrying a CP, and N2 is less than or equal to N;

[0246] Alternatively, the result of rounding up or rounding down 1 / K of the fifth length, the fifth length is equal to the length of N3 OFDM symbols carrying CP, and N3 is less than or equal to N.

[0247] In some embodiments, in this embodiment, the lengths of the L second time-domain resource units are associated with at least one of the following:

[0248] a CP length of at least some OFDM symbols in the M third time domain resource units;

[0249] The length of at least part of the OFDM symbols in the M third time domain resource units that do not carry a CP.

[0250] Here, at least part of the OFDM symbols that do not carry CP in the M third time domain resource units is the remaining part after deducting the time domain resources occupied by the first signal from all OFDM symbols that do not carry CP in the M third time domain resource units.

[0251] That is to say, the length of the L second time domain resource units may be related to the CP length of at least part of the OFDM symbols in the M third time domain resource units, or may be unrelated, such as the length of the L second time domain resource units is the length of the remaining part after deducting the time domain resources occupied by the first signal from the M third time domain resource units.

[0252] Specifically, the length of the L second time domain resource units is equal to the CP length of at least part of the OFDM symbols in the M third time domain resource units; or, the length of the L second time domain resource units is equal to the length of at least part of the OFDM symbols that do not carry CP in the M third time domain resource units; or, the length of the L second time domain resource units is equal to the CP length of at least part of the OFDM symbols in the M third time domain resource units + the length of at least part of the OFDM symbols that do not carry CP.

[0253] The CPs of at least some OFDM symbols in the M third time domain resource units may be understood as: all or part of the CPs of the OFDM symbols in the M third time domain resource units.

[0254] It should also be noted that, in this embodiment, the first time domain resource unit and the second time domain resource unit may be the same or different. For example, if the first time domain resource unit is the same as the second time domain resource unit, the first time domain resource unit may be used to receive or send the first signal and related information of the first signal, that is, the first time domain resource unit is preferably determined based on the OFDM symbol carrying the CP, such as in scheme 6 of FIG7 , where the first time domain resource unit is used to receive or send the first signal and related information of the first signal.

[0255] In some embodiments, in this embodiment, the third time domain resource unit includes at least one of the following:

[0256] Orthogonal frequency division multiplexing OFDM symbol, mini-slot, time slot, subframe, half frame, radio frame.

[0257] In this embodiment, if the boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of M time slots, subframes, half frames or radio frames, assuming M=1, then the boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of one time slot, subframe, half frame or radio frame, that is, the boundaries of the K first time domain resource units are aligned with the boundaries of one time slot, subframe, half frame or radio frame, or the boundaries of the L second time domain resource units are aligned with the boundaries of one time slot, subframe, half frame or radio frame, or the boundaries of the K first time domain resource units and the L second time domain resource units are aligned with the boundaries of one time slot, subframe, half frame or radio frame. Here, since one time slot includes N OFDM OFDM symbols, then aligning with the boundary of a time slot, subframe, half frame or radio frame can be understood as: OFDM The CP of each OFDM symbol in the time slot, subframe, half-frame or radio frame is aligned with N4 times of each OFDM symbol, where N4 is greater than or equal to 1. In some embodiments, all or part of the CP of each OFDM symbol in the time slot, subframe, half-frame or radio frame is used to transmit relevant information of the first signal.

[0258] In this embodiment, if the boundaries of K first time domain resource units and / or L second time domain resource units are aligned with the boundaries of M mini-slots, assuming M=1, then the boundaries of K first time domain resource units and / or L second time domain resource units are aligned with the boundaries of one mini-slot, that is, the boundaries of K first time domain resource units are aligned with the boundaries of one mini-slot, or, the boundaries of L second time domain resource units are aligned with the boundaries of one mini-slot, or, the boundaries of K first time domain resource units and L second time domain resource units are aligned with the boundaries of one mini-slot. Here, one mini-slot includes N5 OFDM symbols, N is greater than or equal to 1, and less than or equal to N OFDM , then aligning with the boundary of a mini-slot can be understood as aligning with N6 times of N5 OFDM symbols, where N6 is greater than or equal to 1. At this time, all or part of the CP of each OFDM symbol in this mini-slot is used to transmit relevant information of the first signal.

[0259] In this embodiment, if the boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of M OFDM symbols, assuming M=1, then the boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of one OFDM symbol, that is, the boundaries of the K first time domain resource units are aligned with the boundaries of one OFDM symbol, or the boundaries of the L second time domain resource units are aligned with the boundaries of one OFDM symbol, or the boundaries of the K first time domain resource units and the L second time domain resource units are aligned with the boundaries of one OFDM symbol. In this case, the CP of this OFDM symbol is used to transmit relevant information of the first signal.

[0260] Specifically, Example 1: The boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of a time slot, which is used for receiving or sending NR signals, also known as an NR time slot. Assume that in a 15kHz subcarrier spacing, the length of an NR time slot is 1ms, including N OFDM An NR system OFDM symbol, where each OFDM symbol includes a CP. In the A-IoT application scenario, an NR time slot can transmit information of K first time domain resource units and / or information of L second time domain resource units with A-IoT-specific purposes, where the value of K is equal to M1+N1, K and M1 are greater than or equal to 1, L and N1 are greater than or equal to 0, and K can be an integer or a non-integer.

[0261] For M1 first time domain resource units, at least one of the following situations is included:

[0262] Case 1: M1 = K1 * N OFDM , where K1 is the number of first time domain resource units corresponding to the length of an OFDM symbol that does not carry a CP.

[0263] Case 2: M1 = K2 * N OFDM , where K2 is the number of time-domain resource units corresponding to the first length of an OFDM symbol carrying CP.

[0264] Case 3: M1 is the number K of the first time domain resource units, where M1 has no correlation with the OFDM symbol.

[0265] The length of each OFDM symbol excluding the CP is fixed, i.e., 2048*κ*2 -μ *Tc, where Tc is the basic time domain resource unit in NR, κ is a constant value of 64, and μ is the subcarrier parameter. For the above three different cases:

[0266] Case 1: The length of each first time-domain resource unit is equal to a result of rounding up or rounding down the first length, and the first length is 1 / K1 of the length of an OFDM symbol not carrying a CP.

[0267] Case 2: The length of each first time-domain resource unit is equal to a result of rounding up or rounding down the second length, and the second length is 1 / K2 of the length of the OFDM symbol carrying the CP.

[0268] Case 3-a: An NR time slot includes K first time domain resource units, and the length of each first time domain resource unit is the result of rounding up or rounding down 1 / K of the third length, and the third length is the length of an NR time slot.

[0269] Case 3-b: An NR time slot includes K first time domain resource units, and the length of each first time domain resource unit is the result of rounding up or rounding down 1 / K of the fourth length, and the fourth length is N OFDM The length of an OFDM symbol without CP, i.e. (2048*κ*2 -μ *Tc)*N OFDM ;

[0270] Case 3-c: An NR time slot includes K first time domain resource units, and the length of each first time domain resource unit is the result of rounding up or rounding down 1 / K of the fifth length, and the fifth length is N OFDM The length of the OFDM symbol carrying the CP is (2048*κ*2 -μ *Tc)*N OFDM +sum(CP within a time slot).

[0271] For N1, N1 is an integer number of first time domain resource units, such as at least one of N1 A-IoT symbols, information bits, etc. For example, when an OFDM symbol includes X1 first time domain resource units, N1 may be smaller than X1.

[0272] For the L second time domain resource units (A-IoT dedicated time domain resource units), the L A-IoT dedicated time domain resource units can be located at least one of the starting position, the ending position, and a specific position of a time slot. Specifically, in scheme 1 shown in FIG4 , the length of the L A-IoT dedicated time domain resource units is equal to the sum of the CP lengths of all or part of the OFDM symbols in an NR time slot, and the positions of the L A-IoT dedicated time domain resource units include at least one of the following:

[0273] Case a: L A-IoT dedicated time domain resource units can be located at the front end of an NR time slot, such as serving as at least one of the following purposes: preamble sequence, midamble sequence, control information, start identifier, and anti-intersymbol interference.

[0274] Case b: L A-IoT-specific time domain resource units can be located at the back end of an NR time slot, such as serving as at least one of data information, termination identifier, processing delay, and anti-intersymbol interference.

[0275] Case c: Of the L A-IoT-specific time-domain resource units, L1 time-domain resource units are located at the front end of an NR time slot, and L2 time-domain resource units are located at the back end of an NR time slot.

[0276] Case d: Of the L A-IoT-specific time domain resource units, L1 time domain resource units are located at specific positions in a time slot, and L1 is less than or equal to L. If L1 is less than L, the remaining L2 time domain resource units are located at the end of an NR time slot.

[0277] Example 2: The boundaries of the K first time domain resource units and / or the L second time domain resource units are aligned with the boundaries of a mini slot, which is used for receiving or transmitting NR signals. A mini slot includes N5 OFDM symbols, where N5 is greater than or equal to 1 and less than N OFDM , N OFDM is the number of OFDM symbols in a time slot.
