For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] To enable those skilled in the art to better understand the embodiments of this disclosure, the following description will be provided first.

[0042] I. Types of Ambient IoT (A-IoT) Devices;

[0043] The 3rd Generation Partnership Project (3GPP) defines three types of A-IoT devices, based on whether they have energy storage capabilities and independent signal transmission capabilities, and classifies them into the following three categories:

[0044] Device 1: Peak power consumption is approximately 1μW, with energy storage function, and initial sampling frequency offset (SFO) is as high as 10. X The device has neither DL nor UL amplification. The UL transmission of this device is backscattered on an externally provided carrier.

[0045] Device 2a: Peak power consumption ≤ several hundred μW, with energy storage function, initial SFO up to 10 X The device has DL and / or UL amplification capabilities. The UL transmission of this device is backscattered on an externally provided carrier.

[0046] Device 2b: Peak power consumption ≤ several hundred μW, with energy storage function, initial SFO up to 10 X ppm, the device has DL and / or UL amplification capabilities. The UL transmission of the device is generated internally.

[0047] II. Backscatter Communication;

[0048] A backscatter communication system consists of an excitation signal source and a signal reflection device. It typically comprises a reader and a reflective tag. The reader generates the radio frequency (RF) excitation signal, while the reflective tag is a device capable of reflecting the RF signal. The reader sends an RF signal to the reflective tag, which receives the signal and reflects it back. By changing the load impedance of the reflective tag's antenna, information is modulated into the backscattered signal. When the reflection coefficient is configured as follows: the first reflection coefficient, the energy of the excitation signal is completely absorbed by the tag antenna; when the reflection coefficient is configured as the second reflection coefficient, the excitation signal is completely reflected; and when the reflection coefficient is configured as the third reflection coefficient, the excitation signal is partially absorbed and partially reflected.

[0049] III. Reader to Device (R2D) signal generation process in A-IoT systems.

[0050] In the A-IoT system, the R2D signal can adopt an on-off keying (OOK)-1 waveform or an OOK-4 waveform based on orthogonal frequency division multiplexing (OFDM), as shown below:

[0051] (1) The R2D signal uses the OOK-1 waveform signal;

[0052] A chip value of 1 means that all carriers of the R2D signal / channel are modulated;

[0053] Chip=0 means that all carriers of the R2D signal / channel have 0 power (from a baseband perspective).

[0054] (2) The R2D signal uses the OOK-4 waveform signal;

[0055] The process of generating the OOK-4 waveform signal of the Discrete Fourier Transform-scaling-OFDM (DFT-s-OFDM) R2D waveform is as follows:

[0056] 1. In the time domain, the OOK signal is an OFDM symbol consisting of M chips.

[0057] 2. A chip is represented by L sampling points (e.g., upsampling);

[0058] 3. Perform an N-point DFT transform on a sample of an OFDM symbol to obtain the frequency domain signal.

[0059] 4. Perform DFT transformation on point N′ in the obtained frequency domain signal and map it onto X subcarriers of R2D.

[0060] 5. Perform an N-point Inverse Discrete Fourier Transform (IDFT) to obtain the R2D time-domain signal.

[0061] IV. Methods for determining the Transmission Block Size (TBS) in NR systems.

[0062] The basic process defined by TBS in the NR system includes:

[0063] 1) Calculate the number of intermediate information bits N based on the number of available resource elements (REs), the number of layers, the modulation order, and the code rate. RE ·υ·Q m·R, where,

[0064] υ represents the number of layers;

[0065] Q m The modulation order;

[0066] R is the bitrate;

[0067] N RE The number of REs;

[0068] N RE =Y * number of PRBs;

[0069] Y is the number of REs in a PRB, obtained by quantization through X. X = 12 * number of scheduled OFDM symbols - Xd - Xoh, where Xd is the number of DMRS REs in a PRB, and Xoh is other overhead including Channel State Information Reference Signal (CSI-RS) and Control-Resource Set (CORESET), which is semi-statically configured by the network side.

[0070] 2) Determine the TBS based on the number of intermediate information bits, and determine the quantized TBS by looking up a table or calculating a formula.

[0071] If N info If the value is ≤3824, then the quantized information bits are:

[0072] here, Select at least N′ according to the table lookup method. info The TBS is defined as a specific TBS, and the corresponding table is shown in Table 1.

[0073] Table 1

[0074] If N info >3824, the quantized information bits are:

[0075] here,

[0076] The TBS is further determined based on the different codes, specifically:

[0077] If R ≤ 1 / 4, then in,

[0078] Otherwise, if R > 1 / 4, then N′ info >8424, in, Other situations

[0079] V. Based on the research phase of A-IoT, the following two methods were proposed for the termination of the Physical Reader-to-Device Channel (PRDCH) transmission:

[0080] Method 1: Obtain TBS information through implicit / explicit Layer 1 (L1) Reader to Device (R2D) control information.

[0081] Method 2: Send a postamble at the end of the PRDCH.

[0082] The following two methods are proposed for ending the PDRCH transmission:

[0083] Method 1: Control information is indicated via R2D.

[0084] Method 2: Send a postamble at the end of the PDRCH.

[0085] The method for determining transport block information provided in this disclosure will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0086] As shown in Figure 1, this embodiment of the present disclosure provides a method for determining transport block information, including:

[0087] Step 101: Obtain first information from the A-IoT device.

[0088] This initial information is used by A-IoT devices to determine the target TBS.

[0089] In some implementations of this disclosure, the first information is predefined by the protocol, or the first information is carried by at least one of the first signaling, the first channel, and the first signal.

[0090] Step 102: The A-IoT device determines the target transport block size (TBS) based on the first information. The target TBS is used to determine the data volume information related to the second channel. The second channel includes at least one of the physical layer reader-to-device channel (PRDCH) and the physical layer device-to-reader channel (PDRCH).

[0091] In some implementations of this disclosure, the data volume information related to the second channel transmission includes at least one of the following: the TBS of the second channel transmission, the transmission time of the second channel, and the transmission-related parameters of the second channel.

[0092] In this embodiment of the disclosure, if the A-IoT device receives the first information, it determines the target TBS based on the first information; if the A-IoT device does not receive the first information, it determines the target TBS according to the protocol.

[0093] The above-described solution of this disclosure enables the A-IoT device to determine the data volume related information of at least one of PRDCH and PDRCH through the first information, and then determines the information length of PRDCH and / or PDRCH transmission based on the data volume related information of at least one of PRDCH and PDRCH, thereby achieving the purpose of knowing the size of PRDCH and / or PDRCH transmission.

[0094] Furthermore, in related technologies, in A-IoT systems, if the postamble is used as the end position indicator for PRDCH and PDRCH transmission, the A-IoT device or reader needs to continuously perform blind detection on the postamble. When there is a sampling frequency offset (SFO), the cumulative error detected by the receiver will increase, thereby increasing the probability of false detection. However, the solution described in this embodiment enables the A-IoT device to determine the data volume information of at least one of the PRDCH and PDRCH through the aforementioned first information, and then determines the information length of the PRDCH and / or PDRCH transmission based on the data volume information of at least one of the PRDCH and PDRCH. This avoids the A-IoT device continuously performing blind detection on the postamble at the end position of channel transmission, thus effectively preventing an increase in the probability of false detection of the postamble.

[0095] In some implementations of this disclosure, the first information includes at least one of the following:

[0096] A1: The target TBS.

[0097] For example, the first information may directly indicate the target TBS transmitted via the second channel.

[0098] In some implementations of this disclosure, different second channels can be defined by a protocol to correspond to one or more specific candidate TBSs. The specific target TBS can be predefined by the protocol and / or further indicated by first information. The target TBS is a TBS among the candidate TBSs.

[0099] The protocol defines different second channels as corresponding to one or more specific candidate TBSs, and the specific target TBS can be further indicated by protocol pre-definition and / or first information.

[0100] A2: TBS related indication information, which is used to indicate information related to the target TBS.

[0101] In some implementations, the TBS-related indication information corresponds to a TBS, and the target TBS corresponding to the TBS-related indication information in the first information is obtained based on this correspondence.

[0102] For example, the TBS-related indication information includes a TBS index value. There is a correspondence between the TBS index value and a TBS; based on the TBS index value and the correspondence in the first information, the target TBS is determined.

[0103] A3: Transmission Time Interval (TTI) information corresponding to TBS.

[0104] In this embodiment of the disclosure, the time unit of TTI can be at least one of the following: L Orthogonal Frequency Division Multiplexing (OFDM) symbols (L is an integer greater than or equal to 1, such as: 1, 2, 7, 14, ...), mini-slot, slot, millisecond (ms), subframe, or radio frame.

[0105] The time unit of TTI can also be 1 / L1 of the OFDM symbol, or a multiple of L2 of the sampling point Tc or Ts, where L1 and L2 are integers greater than or equal to 1.

[0106] A4: Channel waveform information for the second channel.

[0107] In some implementations of this disclosure, the channel waveform information of the second channel includes at least one of the number of chips M per unit time and the chip length, where M is a positive integer;

[0108] The unit time includes at least one of OFDM symbols, milliseconds, and seconds.

[0109] For example, the channel waveform information of the second channel includes at least one of the M value of the on / off keying OOK-4 waveform of the second channel and the chip length.

[0110] For example, the channel waveform information of the second channel includes at least one of the following: the chip length after channel coding or modulation of the second channel, the square wave period after small frequency shift, the number of square wave periods, or half of the square wave.

[0111] A5: Information related to the transmission of the second channel.

[0112] In some implementations of this disclosure, the transmission-related information of the second channel includes at least one of the following:

[0113] The transmission rate of the second channel;

[0114] Specific indication information of the second channel, such as the signal type transmitted by the second channel;

[0115] The coding rate or channel coding code rate of the second channel;

[0116] The modulation scheme or modulation order of the second channel;

[0117] The frequency division factor of the second channel;

[0118] The bandwidth of the second channel;

[0119] The chip length or symbol length of the second channel;

[0120] The transmission time of the second channel;

[0121] Cyclic Redundancy Check (CRC) of the control information and / or data information of the second channel;

[0122] The transmission resource length of the second channel.

[0123] For example, the transmission rate of a query signal is 1 kbits / s, corresponding to TBS #1. The transmission rates of channels carrying commands are 10 kbits / s and 128 kbits / s, corresponding to TBS #2 and TBS #3 respectively. The transmission rate of the randomly accessed Msg1 message is 40 kbits / s, supporting three transmission rates from #1 to #3, corresponding to TBS #4 to TBS #6 respectively. The device can determine the corresponding target TBS based on the specific indication information of the second channel.

[0124] A6: Type information of the second channel;

[0125] Resource length for second channel transmission.

[0126] The second channel corresponding to different types of information can be a PRDCH of different lengths and / or different formats, or it can be a PRDCH channel carrying different types of indication information.

[0127] In some embodiments of this disclosure, the first information and the TBS have a corresponding relationship, and the target TBS corresponding to the first information is obtained based on this correspondence. Alternatively, the target TBS is calculated based on the first information.

[0128] In some implementations of this disclosure, the first channel includes at least one of the following: PRDCH, PDRCH, Physical Downlink Control Channel (PDCCH), or Physical Uplink Control Channel (PUCCH).

[0129] And / or, the first signal includes preamble information of at least one of PRDCH and PDRCH, wherein the preamble information includes at least one of preamble, introductory preamble and postamble.

[0130] In some implementations of this disclosure, the PRDCH in the first channel includes at least one of a PRDCH carrying a paging message and a PRDCH carrying transmission resource information of the second channel.

[0131] For example, the PRDCH carrying the transmission resource information of the second channel can be the PRDCH containing message 0 (Msg0) or the PRDCH containing message 2 (Msg2); here, the PRDCH and the second channel can be the same channel or different channels. For example, the PRDCH carrying the transmission resource information of the second channel is the first channel itself (PRDCH), or the PRDCH carrying the transmission resource information of the second channel is a PRDCH located before the second channel.

[0132] In some implementations of this disclosure, when the A-IoT device determines the target TBS itself, the first channel is a PDRCH. For example, the PDRCH is message 1 (Msg1) or message 3 (Msg3) in the random access process, or a PDRCH used for data transmission, or the first channel itself (PDRCH).

[0133] In some implementations of this disclosure, the second channel transmission includes at least one of the following:

[0134] PRDCH transmission, wherein the PRDCH transmission includes at least one of the transmission of PRDCH control information and data information;

[0135] PDRCH transmission, wherein the PDRCH transmission includes at least one of the transmission of PDRCH control information and data information.

[0136] In some implementations of this disclosure, the PRDCH transmission includes the transmission of a specific type of PRDCH;

[0137] And / or, the PDRCH transmission includes transmissions of a specific type of PDRCH.

[0138] The aforementioned specific type can be a specific service type. This specific type includes at least one of the types used for querying, commanding, locating, or sensing.

[0139] In this embodiment of the disclosure, the second channel and the first information can be the same channel or different channels.

[0140] In some implementations of this disclosure, the target TBS satisfies at least one of the following:

[0141] B1: The duration of the target TBS is the same as the duration of the first time domain resource;

[0142] B2: The first duration is the same as the duration of the first time domain resource, and the first duration is the sum of the duration corresponding to the target TBS and the duration corresponding to the preamble;

[0143] B3: The second duration is the same as the duration of the first time domain resource. The second duration is the sum of the duration corresponding to the target TBS, the duration corresponding to the preamble of the second channel, and the duration corresponding to the N intermediate preambles.

[0144] B4: The third duration is the same as the duration of the first time domain resource. The third duration is the sum of the duration corresponding to the target TBS, the duration corresponding to the preamble of the second channel, the duration corresponding to the N intermediate preambles, and the duration corresponding to the postamble.

[0145] B5: The fourth duration is the same as the duration of the first time domain resource, and the fourth duration is the sum of the duration corresponding to the target TBS and a specific time interval;

[0146] B6: The fifth duration is the same as the duration of the first time domain resource. The fifth duration is the sum of the duration corresponding to the target TBS, the duration corresponding to the preamble of the second channel, the duration corresponding to the N1 intermediate preambles, the duration corresponding to the N2 postambles, and a specific time interval.

[0147] The first time-domain resource includes at least one of M1 OFDM symbols, M2 micro-slots, M3 time slots, M4 subframes, M5 radio frames, M6 seconds, and M7 milliseconds, where N is a positive integer, M1, M2, M3, M4, M5, M6, and M7 are all positive integers, and N1 and N2 are both integers greater than or equal to zero.

[0148] In this embodiment of the disclosure, the target TBS satisfies the above conditions, enabling the second channel transmission to be aligned with the boundary of the first time domain resource, thereby avoiding problems such as interference or waste of time domain resources caused by the overlap of NR signal and A-IoT signal in the time domain.

[0149] In some embodiments of this disclosure, the TBS table includes TBS indication information, namely: the table index value, the corresponding TTI length, and at least two of the following: different waveform parameters, data transmission rate, and preamble, intermezzo, postamble, and special interval. Here, the special interval can be used as a guard interval.

[0150] Among them, TTI is the boundary of time-domain resources in NR, such as at least one of the following: time slot, OFDM symbol, millisecond or second. The time unit of TTI is at least one of the following: time slot, OFDM symbol, millisecond or second.

[0151] For R2D link transmission, TTI includes at least one of the following: Start Indication Part (SIP) in the preamble, Clock Acquisition Part (CAP) in the preamble, PRDCH transmission, indices, postcodes, and guard intervals.

[0152] For D2R link transmission, TTI includes at least one of the following: preamble, PDRCH transmission, intermembrane, postamble, and guard interval.

[0153] For R2D link transmission, taking TTI and slot alignment as an example, it can be represented as follows: TTI = (((TBS+N) CRC ) / R channel_coding_rate +T R2D_CAP ) / M chip_per_OFDM_symbol +T R2D_SIP ) / N OFDM_symbol_per_slot +T Guard_time ,

[0154] in:

[0155] ●TBS is the transport block size of PRDCH.

[0156] ●N CRC This is the CRC bits added to the transport block of the PRDCH. For example, if the transport block is greater than 24 bits, the number of CRC bits is 16; otherwise, the number of CRC bits is 6.

[0164] For D2R link transmission, taking TTI and slot alignment as an example, it can be represented as follows: TTI = ((TBS + N) CRC ) / R channel_coding_rate +T D2R_amble ) / (R bit_rate )+T Guard_time ;

[0170] ●R bit_rate Let R be the data transmission rate of PDRCH, i.e., the bit rate. If FDM transmission is used, i.e., implemented with a small frequency offset, then the following relationship holds: R bit_rate =R chip_rate / (2*R SFS_factor ), where R chip_rate R is the chip rate. SFS_factor It is the SFS factor.

[0172] ●The time unit of TTI is: time slot.

[0173] Taking PRDCH using Manchester encoding as an example, with the Start Indicator (SIP) in the preamble being one OFDM symbol long and the Clock Acquisition (CAP) in the preamble being four chips long, Table 3 shows a 7-bit TBS table (see below). This table lists the TTI lengths and corresponding GTs for the OOK-4 waveform parameters M = {2, 6, 12, 24}. Here, GT only lists the GT required for slot alignment. Based on the GT in the table, N or 1 / N time units can be superimposed, where the time unit is at least one of the following: time slot, OFDM symbol, millisecond, or second.

[0174] Taking PDRCH with 1 / 3 bit rate FEC and a preamble code length of 31 bits as an example, Table 4 is a 7-bit TBS table (see below). This table lists the TTI length and corresponding GT for different bit rates.

[0175] In Tables 3 and 4, only the GTs required for slot alignment are listed. Based on the GTs in the tables, N or 1 / N time units can be superimposed. Here, the time unit is at least one of the following: time slot, OFDM symbol, millisecond, or second.

[0176] For devices with low capabilities, such as device type 1, which only support a few applications and do not require flexible link adaptive transmission, the TBS table for R2D links can be simplified to a 3-digit TBS table, which is a subset of the TBS tables in Table 3, as shown in Table 2.

[0177] Table 2: TBS table corresponding to R2D link (3-bit indication)

[0178] According to the TBS table above, the TBS and corresponding TTI are indicated by the TBS index carried in the control information of the PRDCH. The device will obtain the specific transmission time and TBS of the PRDCH based on the M-value information carried in the R2D preamble and the TBS index in the PRDCH control information. Similarly, the device will obtain the specific TBS based on the bit rate of the PDRCH and the TBS index in the PRDCH control information, and then backscatter or transmit the PDRCH. Since the transmission parameters of the PRDCH and PDRCH can be different, such as bit rate and chip length, the TTI for the same TBS can be different, and the TBS indication information of the PRDCH and PDRCH can be different.

This first information enables the A-IoT device to determine the data volume-related information of at least one of PRDCH and PDRCH, and then determine the information length of the PRDCH and / or PDRCH transmission based on this information. This avoids the A-IoT device continuously performing blind detection on the postcode at the end of the channel transmission, effectively preventing an increase in the false detection probability of the postcode.

[0261] The solution of this disclosure embodiment can, on the one hand, indicate the length of the A-IoT signal with less signaling overhead, and on the other hand, by designing the size of the TBS, the A-IoT signal can be aligned with the boundary of the NR time domain resources, thus avoiding the A-IoT signal from affecting the NR signal.

[0262] The method for determining transport block information disclosed herein will be described below with reference to embodiments.

[0263] Example 1: Application scenarios of TBS.

[0264] This embodiment mainly focuses on the application scenarios of TBS.

[0265] The A-IoT device determines the target TBS for transmission on the second channel based on the first information carried by the protocol predefined, the first channel, the first signaling, and / or the first signal, wherein the first channel includes at least one of the following:

[0266] Case 1: PRDCH channel carrying Paging messages;

[0267] Case 2: A PRDCH channel carrying resource information for the second channel, such as the PRDCH where Msg0 is located, or the PRDCH where Msg2 is located; here, the PRDCH channel and the second channel can be the same channel or different channels.

[0268] For example, if the first channel and the second channel are the same, the control information section of the PRDCH or PDRCH indicates the TBS size of the subsequent data section.

[0269] Scenario 3: PDRCH channel, such as when the A-IoT device determines the TBS size itself, the target TBS can be carried in the control information part of the PDRCH.

[0270] Scenario 4: PDCCH channel or PUCCH; For example, in topology scenario 2, the reader is located on the terminal side. The specific PRDCH and / or PDRCH related transmission information can be sent by the base station to the terminal (reader) through PDCCH. The PRDCH and / or PDRCH related transmission information determined by the terminal (reader) is fed back to the base station through PUCCH.

[0271] The first signal mentioned above can be a preamble of PRDCH or PDRCH.

[0272] Here, the second channel using the target TBS transmission includes at least one of the following cases:

[0273] PRDCH transmission includes the transmission of control information and / or data information of the PRDCH channel, as shown in Figure 3 or Figure 4.

[0274] PDRCH transmission includes the transmission of control information and / or data information of the PDRCH channel, as shown in Figure 5 or Figure 6.

[0275] PDRCH transmissions scheduled by PRDCH, such as the PRDCH where Msg0 is located, or the PRDCH where Msg2 is located; here, the PRDCH channel and the second channel can be the same channel or different channels.

[0276] Control information and / or data information in a PRDCH for a specific service type. Here, the specific service type can be a service type used for at least one of the following: query, command, location, or perception.

[0277] Control information and / or data information in a PDRCH for a specific service type. Here, the specific service type can be at least one service type such as query, command, location or perception.

[0278] The relationship between the first channel and the second channel, or the relationship between the first signal and the second channel, includes at least one of the relationships shown in Figure 7. Wherein: the starting end of the arrow represents the first channel or the first signal, and the ending end of the arrow represents the second channel using the target TBS for transmission.

[0279] Example 2: Method for determining a specific TBS form.

[0280] 1. Taking PRDCH transmission as an example:

[0281] The M value of the PRDCH channel waveform (e.g., OOK-4 waveform), the channel coding code rate of the PRDCH channel is R, the modulation order of the PRDCH channel is K; the time resource length of the PRDCH channel transmission, e.g., N1 OFDM symbols, where N1 is greater than or equal to 1.

[0282] TBS calculation can be performed using at least one of the following methods, meaning that the following calculation methods can be satisfied simultaneously:

[0283] Method 1: The TBS transmission time is N1 times the OFDM symbol length, where N1 is greater than or equal to 1. TBS = N1 * M * K * R - CRC;

[0284] Method 2: TBS is a multiple of a specific number of bits Num, where Num is an integer greater than or equal to 1, such as 8, or a power of 2. TBS = N1 * M * K * R - CRC; Mod(TBS, Num) == 0;

[0285] Mod(*,Num) is the modulo operation on Num.

[0286] Method 3: The transmission time of TBS is aligned with the NR time-domain resource boundary, such as a multiple of K_OSs in OFDM symbols, e.g., K_OSs is 1, 2, 7, 14, etc. TBS = N1 * M * K * R - CRC; Mod(N1, K_OSs) == 0,

[0287] Mod(*,K_OSs) is the modulo operation on K_OSs.

[0288] Furthermore, TBS can have a minimum value TBS_min and / or a maximum value TBS_max, such as a minimum value of 8 or 16 and a maximum value of 1000 or 1024.

[0289] If the PRDCH contains two CRCs, one for control information and one for data information, the TBS calculation method in the above formula is as follows: TBS=N1*M*K*R-CRC#1-CRC#2;

[0290] Or TBS = floor(N1*M*K*R-CRC#1-CRC#2);

[0291] Or TBS = ceiling(N1*M*K*R-CRC#1-CRC#2);

[0292] Or TBS = round(N1*M*K*R - CRC#1 - CRC#2);

[0293] Or TBS=floor(N1*M*K*R-CRC#1-CRC#2)-L_control;

[0294] Or TBS=ceiling(N1*M*K*R-CRC#1-CRC#2)-L_control;

[0295] Or TBS = round(N1*M*K*R-CRC#1-CRC#2)-L_control;

[0296] Where L_control is the length of the control information, floor(*) rounds down from *, ceiling(*) rounds up from *, and round(*) rounds up from * to the nearest integer.

[0297] If the PRDCH contains specific information that does not require CRC verification, its length is L_flag. The TBS calculation method in the above formula is as follows:

[0298] TBS=floor(N1*M*K*R-CRC-L_flag);

[0299] Or TBS = ceiling(N1*M*K*R-CRC-L_flag);

[0300] Or TBS = round(N1*M*K*R-CRC-L_flag);

[0301] Similarly, the above formula also applies to the case where PRDCH includes two CRCs, which will not be elaborated further.

[0302] 2. Taking PDRCH transmission as an example:

[0303] The PDRCH has a transmission rate of data_rate, a transmission time of T_D2R, a coding rate of R, and a channel modulation order of K.

[0304] PDRCH's TBS calculation method includes at least one of the following:

[0305] Method 1: The TBS transmission time is N1 times the OFDM symbol length, where N1 is greater than or equal to 1. TBS = data_rate * T_D2R * R – CRC; Mod(T_D2R, T_OFDM) == 0;

[0306] Here, T_OFDM is the time length of one OFDM symbol.

[0307] Method 2: TBS is a multiple of a specific number of bits Num, where Num is an integer greater than or equal to 1, such as 8, or a power of 2. TBS = data_rate * T_D2R * R – CRC; Mod(TBS, Num) == 0;

[0308] Here, Mod(*,Num) is the modulo operation on Num.

[0309] Method 3: The transmission time of TBS is aligned with the NR time-domain resource boundary, such as a multiple of K_OSs in OFDM symbols, e.g., K_OSs is 1, 2, 7, 14, etc. TBS = data_rate * T_D2R * R – CRC; Mod(N1, K_OSs) == 0,

[0310] Here, mod(*,K_OSs) is the modulo operation of * on K_OSs.

[0311] If the TBS calculated by the above formula is not an integer, then at least one of the following operations can be performed: round down, round up, or take the nearest integer.

[0312] Table 5 shows the TBS step size (taking 8 bits as an example) under different M values ​​of OOK-4. The last five columns in Table 5 refer to the corresponding transmission time length when using the corresponding M value of the OOK-4 waveform. Here, the unit of transmission time length is OFDM symbols. For example, when the M value of the OOK-4 waveform is 2, the transmission time length of TBS with TBS_Index 1 is 14 OFDM symbols.

[0313] Table 5

[0314] Example 3: Candidate TBS list design method one.

[0315] The candidate TBS list is part or all of a specific TBS table. This embodiment uses the candidate TBS list as an example for illustration.

[0316] The selection criteria for the candidate TBS list include at least one of the following:

[0317] Rule 1: The total number of OFDM symbols transmitted by TBS shall not exceed a specific threshold, such as 65 OFDM symbols, or a multiple of the transmission unit. Here, the transmission unit is N² OFDM symbols, where N² is an integer greater than or equal to 1, such as 1, 2, 7, 14, etc. See Table 6 for details.

[0318] Rule 2: The step size of TBS increases or decreases by multiples of a specific step size K or 1 / K, such as: a specific step size of 8 bits, where K is an integer greater than or equal to 1; see Table 7 for details. Different M values ​​result in different step sizes, such as: step = max(8, M*N2), where N2 is an integer. As shown below: where N2 = 2, and the total number of OFDM symbols does not exceed 65 symbols.

[0319] Rule 3: The increment step size of TBS varies under different parameters; here, the parameters include at least one of the following: the M value of the OOK-4 waveform; transmission rate, modulation and coding scheme (MCS), transmission chip length, frequency division factor, bandwidth, etc. For example, see Table 7. The step size varies for different M values, such as: step = max(8, M*N), where N is an integer.

[0320] Guideline 4: The information indication field of the TBS is L bits in size, which can indicate 2^L TBS values, as shown below: 5 bits are used to indicate the TBS size: the case that supports the most M values ​​with the same number of OFDM symbols. See Table 8 for details.

[0321] Rule 5: A TBS with the same information bit length can support a maximum of K1 M values, such as K1 = 3. See Table 9 for details.

[0322] Table 6: The total number of OFDM symbols does not exceed a specific threshold, such as 65 OFDM symbols.

[0323] Table 7: The step size varies with different M values, such as: step = max(8, M*N), where N is an integer, and N = 2. The total number of OFDM symbols does not exceed 65 symbols.

[0324] Table 8: The information indication field of TBS is K bits in size and can indicate 2^K TBS values.

[0325] Table 9: For TBSs with the same information bit length, a maximum of K1 M values ​​can be supported, such as K1 = 3.

[0326] Example 4: Determining the target TBS based on a formula;

[0327] The A-IoT device determines the target TBS based on the transmission-related information of the second channel in the first information and the candidate TBS table. The transmission-related information of the second channel in the first information includes at least one of the following: the M value of the OOK-4 waveform; transmission rate, modulation and coding scheme (MCS), transmission chip length, frequency division factor, bandwidth, etc. Here, the first information can be carried through the first channel. Specific examples are given below.

[0328] Taking PRDCH transmission as an example:

[0329] The M value of the PRDCH channel waveform (e.g., OOK-4 waveform), the channel coding rate R of the PRDCH channel, the modulation scheme or modulation order K of the PRDCH channel; the resource length transmitted by the PRDCH channel includes N1 OFDM symbols.

[0330] The target TBS can be calculated using at least one of the following methods:

[0331] Method 1: The target TBS is a multiple of a specific number of bits Num, where Num is an integer greater than or equal to 1, such as 8, or a power of 2. TBS = ceiling((N1*M*K*R-CRC) / Num)*Num;

[0332] Here, ceiling(*) represents the floor function.

[0333] If TBS is less than the minimum value TBS_min or greater than the maximum value TBS_max, then the target TBS is TBS_min or TBS_max. Here, TBS has requirements for a minimum value TBS_min and / or a maximum value TBS_max, such as: the minimum value is 8 or 16, and the maximum value is 1000 or 1024;

[0334] If TBS is greater than the minimum value TBS_min and less than the maximum value TBS_max, then the TBS calculated above determines the target TBS:

[0335] Method 2: The transmission time T of TBS is aligned with the NR time-domain resource boundary, such as a multiple of K_OSs in OFDM symbols, such as K_OSs being 1, 2, 7, 14, etc. N_final = floor(N1 / K_OSs) * K_OSs; TBS = N_final * M * K * R - CRC;

[0336] Here, the calculated TBS is the target TBS.

[0337] Table 10 below shows the TBS corresponding to slot-based R2D, Table 11 shows the TBS corresponding to slot-based D2R, Table 12 shows the TBS for R2D corresponding to TBS indices 1-8 (i.e., 3-bit indication information), and Table 13 shows the TBS for D2R corresponding to TBS indices 1-8 (i.e., 3-bit indication information). In the tables, M represents the number of chips in each OFDM symbol.

[0341] Table 13

[0342] Method 3: Based on the calculated TBS, determine the target TBS from the candidate TBS table;

[0343] The TBS is calculated based on either Method 1 or Method 2. The target TBS is the candidate TBS in the table with the smallest difference from the TBS, or the nearest value smaller than the TBS, or the nearest value larger than the TBS.

[0344] The solution of this disclosure embodiment can, on the one hand, indicate the length of the A-IoT signal with less signaling overhead, and on the other hand, by designing the size of the TBS, the A-IoT signal can be aligned with the boundary of the NR time domain resources, thus avoiding the A-IoT signal from affecting the NR signal.

[0345] As shown in Figure 8, this embodiment of the present disclosure provides a device for determining transmission block information, which is applied to an Internet of Things (A-IoT) device, including a memory 820, a transceiver 800, and a processor 810;

[0346] The memory 820 is used to store computer programs; the transceiver 800 is used to send and receive data under the control of the processor 810; the processor 810 is used to read the computer program in the memory 820 and perform the following operations:
