Optionally, the wireless communication system may include at least two control nodes and each control node may include other numbers of A-IoT devices within its coverage area, and the embodiment of the present application does not limit this.

[0050] To facilitate a better understanding of the embodiments of the present application, the A-IoT devices related to the present application are described.

[0051] In NR systems, A-IoT devices can be characterized based on their energy storage capacity and their ability to generate RF signals for transmission. An A-IoT device has one of the following energy storage capabilities: Storage Capacity 1: No energy storage capability; Storage Capacity 2: Energy storage up to E1 or E2 joules, with the possibility that E1 = E2; Storage Capacity 3: Energy storage up to E2 joules. Depending on these storage capabilities, a group of A-IoT devices can be as follows: Device A: No energy storage and no independent signal generation / amplification, such as backscatter transmission; Device B: Energy storage and no independent signal generation, such as backscatter transmission, where the use of stored energy may include amplification of reflected signals; Device C: Energy storage and independent signal generation, such as active RF components for transmission.

[0052] To facilitate a better understanding of the embodiments of the present application, the A-IoT data / service types related to the present application are explained.

[0053] Device-originated (DO) and device-terminated (DT); DO and DT data indicate that the data stream originates from an A-IoT device (similar to an RFID tag) or is transmitted to an A-IoT device. For data streams originating from A-IoT devices, such as DO data, they can be further classified into: DO-A and DO-DTT. DO-A, such as DO autonomously initiates data transmission, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary. DO-DTT, such as device-terminated data triggers device-initiated data transmission, such as asset identification, status reporting, and tracking, which are all downlink triggered reports. The Reader collects data from the tag by triggering the inventory program. Since the data is generated / initiated in the IoT device, this service should be regarded as a tag-initiated DO service triggered by a command sent by the Reader.

[0054] To facilitate a better understanding of the embodiments of the present application, the A-IoT system deployment scenario related to the present application is described.

[0055] The deployment of A-IoT devices can be divided into the following three scenarios:

[0056] Scenario 1: A-IoT devices are deployed within the NR system bandwidth, also known as in-band deployment. In Scenario 1, in one implementation, the same base station serves both the A-IoT device and the NR UE, while in another implementation, different base stations serve both. Scenario 2: A-IoT is deployed within the NR system's guard band, also known as guard band deployment. In this scenario, in one implementation, the same base station serves both the A-IoT device and the NR UE, while in another implementation, different base stations serve both. Scenario 3: A-IoT is deployed outside the NR system's guard band (obviously, also outside the NR system bandwidth), also known as stand-alone deployment. In Scenario 3, the base station typically serves only the A-IoT device.

[0057] To facilitate a better understanding of the embodiments of the present application, the delimiters and terminators in the RFID related to the present application are explained.

[0058] In an RFID system, to determine the starting point of a signal, a delimiter is usually sent before the payload, or a specific sequence (preamble) is sent. For example, a reader sends a signal to a tag, and the signal starts with a specific preamble, where the starting part of the preamble is a specific delimiter. In an RFID system, to determine the end point of a signal, a signal end-of-signaling is usually sent after the payload ends. For example, frequency modulation (FM) coding or Miller coding uses a dummy data 1 bit as the end-of-signaling. For example, the signal end-of-signaling of FM0 is shown in Figure 2, and dummy 1 (dummy1) is the signal end-of-signaling. For another example, the signal end-of-signaling of Miller is shown in Figure 3, and dummy 1 (dummy1) is the signal end-of-signaling.

[0059] To facilitate a better understanding of the embodiments of the present application, the method for determining the NR transmission block size (TBS) related to the present application is described.

[0060] The steps to determine the TBS size in NR are as follows:

[0061] 1) UE determines the number of resource elements (RE) in the slot (N RE ).

[0062] N' RE : Indicates the number of resource elements (REs) available for data transmission in each resource block (RB);

[0063] Indicates the number of subcarriers in a PRB;

[0064] The number of symbols allocated to the Physical Downlink Shared Channel (PDSCH) in a slot;

[0065] The number of REs occupied by the demodulation reference signal (DMRS) on each physical resource block (PRB) within this scheduling period (indicated by DCI format 1_1, DCI format 1_2, or DCI format 1_0);

[0066] Header overhead, configured by the higher-layer parameter xOverhead in PDSCH-ServingCellConfig;

[0067] N RE =min(156,N' RE )·n PRB , within the bandwidth of a single resource block, it is assumed that the UE will not be allocated resources exceeding 156 REs.

[0068] 2) Convert the total number of REs available for data transmission into the number of information bits (N info ).

[0069] N info =N RE ·R·Q m υ, where R is the bit rate; Q is the bit rate. m : modulation order; υ: number of MIMO (Multiple Input Multiple Output) layers.

[0070] The modulation order and target code rate are extracted from the Modulation and Coding Scheme (MCS) table. If the PDSCH resource allocation is received using DCI 1_0, the number of layers is fixed at 1. Otherwise, the number of layers is obtained by looking up the "Antenna Ports" column in the "DMRS Ports" column of the DCI 1_1 table. The number of layers is equal to the number of allocated DMRS ports.

[0071] If N info ≤3824, use step 3 as the next step in TBS determination; otherwise, use step 4 as the next step in TBS determination.

[0072] 3)N info ≤3824, TBS is calculated by the following formula, and the specific parameter values ​​can be shown in Table 1:

[0073] 4)N info >3824, TBS determined as follows:

[0074] in,

[0075] If R≤1 / 4, in,

[0076] like' Ninfo >8424, TBS determined as follows: in,

[0077] otherwise,

[0078] Table 1 N info TBS ≤ 3824

[0079] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0080] In NR systems, the size of the uplink or downlink payload (expressed as the transport block size in NR / LTE systems) is determined by the base station and communicated to the UE, for example, through downlink control information (DCI). The DCI indicates the time-frequency resources and MCS information. The UE receives the downlink signal on the corresponding physical resources based on the time-frequency resource information indicated in the DCI and determines the TBS based on the time-frequency resources, MCS information, and reference signals. This approach cannot support situations with uncertain payloads.

[0081] In an RFID system, the payload sent by a tag to a reader may be uncertain. The tag can help the reader determine the start and end time of the tag signal transmission by sending a specific preamble (which may include a delimiter) before the payload begins and a specific ending-of-signaling after the payload ends, thereby determining the payload size. If this method is used for A-IoT devices, it will lead to low network resource efficiency. For example, when the payload of the signal transmitted by the A-IoT device has a large variable range, the variable range of the occupied time resources is also large. Since the base station cannot predict the resources actually occupied by the A-IoT device, the base station cannot allocate the unused resources of the A-IoT device to other A-IoT devices or use them for NR communication in a timely manner.

[0082] Based on the above technical problems, the present application proposes a transmission solution based on variable load, in which the first device (transmitting end) can independently select the corresponding load for transmission within the controllable range of the second device (receiving end) (controllable load set or load range), which can reduce the receiving complexity of the second device (receiving end) and solve the problem that the second device (receiving end) cannot predict the transmission load of the first device (transmitting end).

[0083] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application.

[0112] In some embodiments, the time domain resource information includes, but is not limited to, at least one of the following: at least one set of time length related information and at least one start time. For example, in this embodiment, the second device sends time domain resource information available for transmission to the first device, allowing the first device to determine a corresponding load set or load range for the first device's transmission based on the indicated time domain resource information for the first device's transmission. This ensures that the load set or load range corresponding to the first device's transmission meets the controllable range of the second device in the time domain.

[0113] Exemplarily, the start time of the transmission of the first device may also be determined by the first device itself, or the start time of the transmission of the first device may also be determined based on a periodic transmission configuration.

[0114] In some embodiments, each set of time length related information in at least one set of time length related information includes but is not limited to at least one of the following: reference time length, time length adjustment information, available unique time length, at least two available time lengths, and at least one available time length set.

[0115] Exemplarily, the reference time length may be a minimum time length, a maximum time length, or any other time length. Optionally, the minimum time length is at least one basic time unit. For example, the basic time unit is one of the following: symbol, time slot, sub-time slot, subframe, frame, microsecond, millisecond, second, minute, or hour.

[0116] Exemplarily, the reference time length is the maximum time length that can be occupied by a single transmission by the first device. The time length available for transmission by the first device is determined based on the maximum time length and the minimum time length, and the first device determines a corresponding load set or load range for transmission based on the available time length. The minimum time length is predefined, or configured / indicated. For example, the minimum time length is at least one basic time unit.

[0117] For example, the maximum time length is 10 time slots, and the minimum time length is predefined as a basic time unit (assuming 1 time slot). Then the time length available for the first device to transmit is 1 to 10 time slots.

[0118] Exemplarily, the first device determines a maximum available payload size based on the maximum time length, and determines a minimum available payload size based on the minimum time length. For example, the first device determines a payload range corresponding to the transmission based on the maximum time length and the minimum time length. The payload size that the first device can select is not greater than the maximum payload and not less than the minimum payload, and the first device determines the duration of the transmission based on the selected payload.

[0119] In some embodiments, the time length adjustment information includes but is not limited to at least one of the following:

[0120] The step information for adjusting the time length, the adjustment factor for adjusting the time length, and the number of different time lengths supported.

[0121] Specifically, the time length adjustment information is information about an adjustable time length transmitted by the first device.

[0122] Optionally, the time length adjustment step information may include one or more step sizes, where the step size may be a positive or negative value. For example, "adjustment" may refer to increasing or decreasing the time length. Optionally, if the time length adjustment information does not include the time length adjustment step size information, the time length adjustment step size information may be agreed upon by the protocol.

[0123] For example, the step length information for adjusting the time length is an X, or the step length information for adjusting the time length is a group of step lengths {X1, X2, . . . , Xn}.

[0124] Exemplarily, the first device may determine the available time length based on the difference between the maximum time length and each step length. For example, if the maximum time length is 10 time slots, the step length is X1 = 2 time slots, and X2 = 4 time slots, then the available time length is 10-2 = 8 time slots and 10-4 = 6 time slots.

[0125] Exemplarily, the first device may determine the available time length based on the difference between the last available time length and the step length. The first time length is determined based on the difference between the maximum time length and one step length. For example, if the maximum time length is 10 time slots, the step length is X1 = 2 time slots, and X2 = 4 time slots, then the available time length is 10-2 = 8 time slots, and 8-4 = 4 time slots. For another example, if the maximum time length is 10 time slots and the step length is 4 time slots, then the available time length is 10-4 = 6 time slots, and 6-4 = 2 time slots.

[0126] Optionally, the scaling factor for adjusting the duration may include one or more scaling factors, where "scaling" may refer to increasing or decreasing the duration. Optionally, if the duration adjustment information does not include the scaling factor for adjusting the duration, the scaling factor for adjusting the duration may be agreed upon by the protocol.

[0127] Exemplarily, the first device may determine the available time length based on the product or quotient of the maximum time length and each scaling factor. Optionally, the resulting product or quotient may be rounded, for example, by rounding up, rounding down, or rounding off; or, the resulting product or quotient may be quantized to an integer multiple of k, for example, k = 1 time slot, if the available time length is an integer number of time slots.

[0128] Exemplarily, the first device may determine the available time length based on the product or quotient of the last available time length and a scaling factor. The first time length is determined based on the product or quotient of the maximum time length and a scaling factor. Optionally, the resulting product or quotient may be rounded, for example, to an integer, or to an integer; or, the resulting product or quotient may be quantized to an integer multiple of k, for example, k = 1 time slot, if the available time length is an integer number of time slots.

[0129] Exemplarily, if a reference time length T and a set of adjustment factors [1 / 4, 1 / 2, 2, 4] for adjusting the time length are given, the first device can determine the available time length based on the product or quotient of the reference time length T and [1 / 4, 1 / 2, 2, 4].

[0130] Optionally, the number of different time lengths that can be supported can be obtained implicitly, such as determined according to the number of steps included in the step information for adjusting the time length or the number of adjustment factors for adjusting the time length. For example, if the step information for adjusting the time length includes N steps, then the number of different time lengths that can be supported is N or less than N (for example, if the time length determined according to the step is less than the minimum time length, this part of the time length needs to be discarded). Another example, if the number of adjustment factors for adjusting the time length is N, then the number of different time lengths that can be supported is N or less than N (for example, if the time length determined according to the adjustment factor is less than the minimum time length, this part of the time length needs to be discarded).

[0131] Optionally, the number M of different time lengths that can be supported can be configured explicitly. For example, if the step information for adjusting the time length includes N steps, the actual available different time lengths are M, or the actual available different time lengths are N (for example, if N < M), or the actual available different time lengths are L (if the time length determined according to the step and / or M is less than the minimum time length).

[0132] Exemplarily, the minimum time length is predefined or configured / indicated. For example, the minimum time length is at least one basic time unit.

[0133] Exemplarily, if the number of different time lengths that can be supported is not indicated, it can be determined according to a predefined value.

[0134] Exemplarily, the time length information is the minimum time length that can be occupied by the transmission of the first device, and the time length adjustment information is the time length information that can be adjusted for the transmission of the first device. The available time length for the transmission of the first device is determined according to the minimum time length and the adjustable time length information, or the available time length for the transmission of the first device is determined according to the minimum time length, the adjustable time length information, and the maximum time length.

[0135] For example, the minimum time length is 2 time slots, the scaling factor is 3, and the number of different time lengths that can be supported is 2. Then, the available time lengths are 2 * 3 = 6 time slots and 6 * 3 = 18 time slots.

[0136] In some embodiments, the second device configures multiple sets of time length adjustment information through high-layer signaling, and each set of time length adjustment information includes at least one of the following: step information for adjusting the time length, adjustment factor for adjusting the time length, and the number of different time lengths that can be supported. The second device dynamically indicates which set of time length adjustment information to use or activate through physical layer control signaling.

[0146] Exemplarily, the second device configures eight time length sets through high-layer signaling, each time length set including one or more time lengths. The second device dynamically indicates which time length set it is using three bits in the physical layer control signaling. Assuming that the set of time lengths indicated by the second device is {2, 4, 6, 8} time slots, then the time lengths available for transmission by the first device are {2, 4, 6, 8} time slots. The first device determines the available payload size (e.g., payload set or payload range) based on the available time lengths (e.g., {2, 4, 6, 8} time slots).

[0147] Exemplarily, the protocol predefines one or more time lengths. For example, the minimum time length is 1 ms, and the protocol definition or the second device configures the first device to use 3 bits to indicate the actual time unit used, thereby supporting time lengths of {1, 2, 3, 4, 5, 6, 7, 8} ms.

A set of time length related information to be used or activated can be determined based on at least one information field in the control information scheduling the transmission of the first device. For example, the time domain resource information includes two sets of time length related information, respectively designated as time length information group 1 and time length information group 2. If a specific bit in the information field indicating time domain resources in the control information scheduling the transmission of the first device has a value of 0, time length information group 1 is used or activated; if a specific bit in the information field indicating time domain resources in the control information scheduling the transmission of the first device has a value of 1, time length information group 2 is used or activated.

[0166] Exemplarily, the first device reports to the second device a set of time length related information used or activated. For example, this is indicated directly or indirectly through a random access uplink message (such as msg1 or msg3 in four-step random access, or msgA in two-step random access). For another example, this is indicated by the capabilities of another first device. For another example, a first device that supports certain power levels, modulation modes, or waveforms uses or activates a certain time length information group.

[0167] In some embodiments, each set of time length related information in the at least one set of time length related information is used to determine the available time length for a single transmission by the first device, or each set of time length related information in the at least one set of time length related information is used to determine the total available time length for R repeated transmissions by the first device, where R is a positive integer. This embodiment can be applied to both single transmissions and repeated transmissions, and can flexibly implement transmissions of different granularities.

[0168] For example, if the transmission of the first device is based on repeated transmission (R repetitions), the reference time length or time length adjustment information included in each set of time length related information in at least one set of time length related information is used to determine the available time length for a single transmission, for example, the indicated maximum time length (such as the reference time length is the maximum time length) and the step length determine the available time length for a single transmission, and the time length of each repeated transmission is the same. Alternatively, the indicated reference time length or time length adjustment information is used to determine the total length of R transmissions, for example, the indicated maximum time length (such as the reference time length is the maximum time length) and the step length determine the available time length for the total length of R transmissions, and the available time length for each transmission is determined based on the total length and R.

[0169] In some embodiments, when the transmission of the first device includes data, some or all of the parameters included in each set of time length related information in the at least one set of time length related information are used to determine the available time length for data transmission. For example, if the transmission of the first device includes only data (payload), the reference time length or time length adjustment information included in each set of time length related information in the at least one set of time length related information is used to determine the available time length for data transmission. This embodiment can be applied to transmissions including data, and can determine the available time length for data transmission, thereby ensuring that the data transmission load is within a controllable range.

[0170] In some embodiments, when the transmission of the first device includes data and a first signal, some or all of the parameters included in each set of the at least one set of time length related information are used to determine the available time length for data transmission, or some or all of the parameters included in each set of the at least one set of time length related information are used to determine the available time length for data and the first signal transmission. This embodiment can be applied to transmissions including data and a first signal, and can determine the available time length for data transmission or first signal transmission, thereby ensuring that the transmission load of the data or first signal is within a controllable range.

[0171] Optionally, the first signal includes but is not limited to at least one of the following: a preamble, a delimiter, a terminator, and a gap (GAP). It should be noted that the gap (GAP) is a portion that needs to be left blank during transmission.

[0172] Exemplarily, in the case where the transmission of the first device includes data and a first signal, each set of time length related information in at least one set of time length related information includes at least two available time lengths as time length information for the data, or, each set of time length related information in at least one set of time length related information includes at least one available time length set as time length information for the data.

[0173] Exemplarily, in the case where the transmission of the first device includes data and a first signal, each set of time length related information in at least one set of time length related information includes at least two available time lengths as time length information of the data and the first signal, or, each set of time length related information in at least one set of time length related information includes at least one available time length set as time length information of the data and the first signal.

[0174] Exemplarily, in the case where the transmission of the first device includes data and the first signal, the time length adjustment information included in each set of the at least one set of time length related information is used to adjust the time length of the data.

[0175] Exemplarily, when the transmission of the first device includes data and a first signal, the time length adjustment information included in each set of at least one set of time length related information is used to adjust the time length of the data and the first signal.

[0176] Exemplarily, in the case where the transmission of the first device includes data and the first signal, the reference time length included in each set of the at least one set of time length related information is the time length information of the data.

[0177] Exemplarily, when the transmission of the first device includes data and the first signal, the reference time length included in each set of the at least one set of time length related information is the time length information of the data and the first signal.

[0178] Exemplarily, if the transmission of the first device includes data (payload), and one piece of time length information included in each of at least one set of time length related information is time length information of the data and the first signal, the time length adjustment information included in each of at least one set of time length related information is used to adjust the time length of the data, wherein the adjustment is performed using an integer number of time units occupied by the data portion. For example, the first S1 symbols in the first time slot are preamble, the remaining S2 symbols are data, and all symbols in the second time slot (S1+S2 symbols) are data. Then, although the data portion occupies part of the time resources of 1 complete time slot + 1 time slot, only the integer number of time units occupied by the data portion, such as 1 time slot, is used in combination with an adjustment parameter for adjustment. For another example, the time length adjustment information is used to adjust the time length of the data, wherein the adjustment is performed using all time resources occupied by the data portion, such as based on 1 complete time slot + S2 symbols in 1 time slot in combination with an adjustment parameter.

[0179] In Example 1, each set of time length related information in the at least one set of time length related information includes a reference time length and time length adjustment information, where the reference time length is time length information of the data and the first signal, and the time length adjustment information is used to adjust the time length of the data. The time length of the first signal is not determined based on this information; for example, the time length of the preamble is predefined.

[0180] Optionally, in Example 1, the first device determines that the maximum time length of the data is 8 time slots based on the reference time length (e.g., maximum time length = 9 time slots) and the time length of the first signal (e.g., the preamble length is 1 time slot). Furthermore, based on the maximum time length of the data and the time length adjustment information (e.g., step length = 2, the number of optional time lengths is 4), the first device determines that the available time lengths for the data are 8, 6, 4, and 2 time slots, as shown in FIG5 .

[0181] Optionally, in Example 1, the reference time length is the maximum time length = 9 time slots. In the first time slot, the first signal occupies S1 symbols, and the data occupies the remaining S2 symbols. In the second to eighth time slots, the data occupies all time slots (S1 + S2 symbols). Then, using the integer number of time units occupied by the data portion, 8 time slots, and the time length adjustment information (for example, scaling factor = 2, the number of optional time lengths is 2), it is determined that the available complete time length for the data is 8 and 4 time slots. Then, all time resources available for the data are S2 symbols + 8 time slots, or S2 symbols + 4 time slots, as shown in Figure 6.

[0182] In Example 2, each set of time length related information in the at least one set of time length related information includes a reference time length and time length adjustment information, where the reference time length is time length information of the data, and the time length adjustment information is used to adjust the time length of the data. The time length of the first signal is not determined based on this information.

[0183] In Example 2, the first device determines the maximum time length of the data as 8 time slots based on the reference time length (e.g., maximum time length = 8 time slots), and determines the available time lengths for the data as 8, 6, 4, and 2 time slots based on the maximum time length of the data and the time length adjustment information (e.g., step length = 2, the number of selectable time lengths is 4). If the time length selected by the first device is 4 time slots, then the first transmission occupies a total of 5 time slots, and the first signal occupies 1 time slot.

[0184] In Example 3, each set of time length related information in the at least one set of time length related information includes a reference time length and time length adjustment information, where the reference time length is time length information of the data and the first signal, and the time length adjustment information is used to adjust the time length of the data and the first signal. The time length of the first signal is predefined.

[0185] In Example 3, the first device transmission is based on repetition (R = 2 repetitions), and each repetition includes a first signal (such as a preamble) and data of the same length. The reference time length is the maximum value of the total length of the R transmissions = 12 time slots, and the preamble is fixed to 1 time slot. The time length adjustment information is scaling factor = 1 / 2. Then the total length of the R transmissions is 6 time slots or 12 time slots. Then, the total length of a single repeated transmission is 3 time slots (preamble is 1 time slot, data is 2 time slots) or 6 time slots (preamble is 1 time slot, data is 5 time slots), as shown in Figure 7.

[0186] In some embodiments, the load control information includes, but is not limited to, at least one of the following: at least one load set or load range, a reference load, and load adjustment information. For example, in this embodiment, the second device sends load control information applicable to the first device's transmission, enabling the first device to determine the corresponding load set or load range for the first device's transmission based on the indicated load control information. This ensures that the load set or load range corresponding to the first device's transmission meets the controllable range of the second device in the time domain.

[0187] Illustratively, the reference load may be a minimum load, a maximum load, or other loads.

[0188] Exemplarily, the reference load is the maximum load of a single transmission of the first device. The load range corresponding to the transmission of the first device can be determined based on the maximum load and the minimum load, wherein the minimum load is predefined, or configured / indicated.

[0189] Exemplarily, the second device indicates a maximum load and a minimum load; wherein the load available for transmission of the first device is not greater than the maximum load and not less than the minimum load.

[0190] Exemplarily, the second device configures or predefines a load table for the first device, and the second device indicates a load index, wherein the load corresponding to the load index is a maximum available load or a minimum available load.

[0191] In some embodiments, the load adjustment information includes but is not limited to at least one of the following: step information for adjusting the load, an adjustment factor for adjusting the load, and the number of different loads that can be supported.

[0192] Specifically, the load adjustment information is load information that can be adjusted transmitted by the first device.

[0193] Optionally, the load adjustment step size information may include one or more step sizes, where the step size may be positive or negative. For example, "adjustment" may refer to increasing or decreasing the load size. Optionally, if the load adjustment information does not include the load adjustment step size information, the load adjustment step size information may be agreed upon by the protocol.

[0194] Exemplarily, the load adjustment step size information is the load adjustment step size, or the load adjustment step size information is the step size index corresponding to the load adjustment. For example, the second device configures or predefines a load table for the first device. Each load in the load table corresponds to an index. If the index value of the maximum load indicated by the second device is 8 and the step size is 2, the available loads are the load values ​​corresponding to the index values ​​8, 6, 4, and 2.

[0195] Optionally, the load scaling factor may include one or more scaling factors, where "scaling" may refer to increasing or decreasing the load size. Optionally, if the load scaling information does not include the load scaling factor, the load scaling factor may be agreed upon by the protocol.

[0196] For example, the payload size obtained by adjusting the payload adjustment factor may be rounded, for example, to an integer, to an integer, or to an integer. Alternatively, the payload size obtained by adjusting the payload adjustment factor may be quantized to an integer multiple of k, for example, k=8 bits.

[0197] Exemplarily, the adjustment factor for adjusting the load is the adjustment factor of the index corresponding to the load.

[0198] Optionally, the number of different loads that can be supported can be obtained implicitly, such as by determining the number of steps included in the step information for adjusting the load or the number of adjustment factors for adjusting the load. For example, if the step information for adjusting the load includes N steps, then the number of different loads that can be supported is N or less than N (for example, if the load determined based on the step is less than the minimum load, this part of the load needs to be discarded). For another example, if the number of adjustment factors of the adjustment factor for adjusting the load is N, then the number of different loads that can be supported is N or less than N (for example, if the load determined based on the adjustment factor is less than the minimum load, this part of the load needs to be discarded).

[0199] Optionally, the number of different loads that can be supported can be displayed in the configuration.

[0200] For example, if the number of different loads that can be supported is not indicated, it can be determined based on a predefined value.

[0201] In some embodiments, the at least one load set or load range is characterized by a minimum load and a load adjustment step size, or the at least one load set or load range is characterized by a maximum load and a load adjustment step size.

[0202] Exemplarily, the load set may include: minimum load, minimum load+adjustment step size, minimum load+2×adjustment step size, minimum load+3×adjustment step size, and minimum load+4×adjustment step size.

[0203] Exemplarily, the load set may include: maximum load - 4×adjustment step size, maximum load - 3×adjustment step size, maximum load - 2×adjustment step size, maximum load - adjustment step size, maximum load.

[0204] Exemplarily, the load range may include: [minimum load, minimum load+5×adjustment step size].

[0205] Exemplarily, the load range may include: [maximum load - 5×adjustment step size, maximum load].

[0206] In some embodiments, a load set or load range used or activated in the at least one load set or load range is determined based on at least one of the following:

For example, the load control information includes two load sets or load ranges, which are respectively recorded as load set or load range 1 and load set or load range 2; wherein, if the first device supports service type 1 or the transmission of the first device corresponds to service type 1, load set or load range 1 is used or activated; if the first device supports service type 2 or the transmission of the first device corresponds to service type 2, load set or load range 2 is used or activated. For example, service type 1 is a delay-sensitive service, and service type 2 is a non-delay-sensitive service. This embodiment associates service types with load sets or load ranges, and can determine a group of load sets or load ranges to be used or activated based on the service type, so that the load available for transmission by the first device can be determined more accurately.

A load set or load range to be used or activated may be determined based on a waveform supported by the first device, or a load set or load range to be used or activated may be determined based on a waveform corresponding to the transmission of the first device.

[0236] The first device determines a maximum time length available for the first transmission according to the time domain resource information, and determines a maximum load corresponding to the first transmission according to the maximum time length available for the first transmission; or,

[0237] The first device determines, according to the time domain resource information, a minimum time length available for the first transmission, and determines, according to the minimum time length available for the first transmission, a minimum load corresponding to the first transmission; or,

[0238] The first device determines a maximum time length and a minimum time length available for the first transmission according to the time domain resource information, and determines a maximum load and a minimum load corresponding to the first transmission according to the maximum time length and the minimum time length available for the first transmission.

[0239] For example, each group of time length related information in at least one group of time length related information includes at least two available time lengths, and the first device can randomly select a time length from the at least two available time lengths as the time length available for the first transmission, or, the first device selects a time length from the at least two available time lengths in order from large to small as the time length available for the first transmission, or, the first device selects a time length from the at least two available time lengths in order from small to large as the time length available for the first transmission, or, the first device selects a time length from the at least two available time lengths in order from small to large according to the identification or index of the time length, or, the first device selects a time length from the at least two available time lengths in order from large to small according to the identification or index of the time length as the time length available for the first transmission.

[0240] For example, each set of time length related information in at least one set of time length related information includes a set of available time lengths, and the first device can randomly select a time length from the time length set as the time length available for the first transmission, or, the first device selects a time length from the time length set in order from large to small as the time length available for the first transmission, or, the first device selects a time length from the time length set in order from small to large as the time length available for the first transmission, or, the first device selects a time length from the time length set in order from small to large according to the identification or index of the time length, or, the first device selects a time length from the time length set in order from large to small according to the identification or index of the time length as the time length available for the first transmission.

[0241] In some embodiments, when the first information includes load control information, the above S230 may specifically include:

[0242] The first device determines a load set or a load range corresponding to the first transmission according to the load control information.

[0243] Exemplarily, the load size selected by the first device is not greater than the maximum load and not less than the minimum load. Optionally, the load selected by the first device must meet specific conditions. For example, the time length corresponding to the selected load is an integer multiple of k, such as k = 1 time slot. For example, the selected load belongs to a predefined or preconfigured load table.

[0244] Exemplarily, the first device determines a set of available payload sizes based on the load adjustment information and the maximum or minimum load. The payload size selected by the first device for transmission by the first device belongs to the set of payload sizes. For example, if the load adjustment information is scaling factor = 2, the number of supported payload sizes is 4, and the payload size determined based on the maximum time length is transmission block size (TBS) 1, the first device can select the following loads: TBS1, TBS1 / 2, TBS1 / 4, or TBS1 / 8. Optionally, the payload size determined based on the maximum or minimum load and the adjustment parameter can be rounded, for example, by rounding up, rounding down, or rounding to the nearest integer. Alternatively, the payload size determined based on the maximum or minimum load and the adjustment parameter can be quantized to an integer multiple of k, for example, k = 8. Optionally, based on the load TBSx determined based on the maximum or minimum load and the adjustment parameter, a load TBS is found in a predefined or preconfigured load table that is closest to and not less than TBSx, or closest to and not greater than TBSx.

[0245] In some embodiments, when the first information includes time domain resource information and modulation and coding repetition transmission information, the above S230 may specifically include:

[0246] The first device determines the time length available for the first transmission based on the time domain resource information, and determines the load set or load range corresponding to the first transmission based on the time length available for the first transmission and the modulation and coding repetition transmission information.

[0247] Exemplarily, the time domain resource information includes a unique time length L, the modulation coding repetition transmission information includes a set of code rates {rate1, rate 2, rate 3, rate 4}, and the first device can determine 4 possible loads based on the unique time length L and the 4 code rates.

[0248] Exemplarily, the load adjustment information and the modulation, coding, and repetition information are separately indicated. The second device provides the modulation, coding, and repetition information, and the second device also provides an adjustment factor (scaling factor) for at least one parameter (e.g., a coding rate or a number of repetitions) of the modulation, coding, and repetition information. For example, the second device provides a coding parameter, coding rate = 1 / 2, provides a repetition parameter, R = 2, and provides a scaling factor = 1 / 2 for adjusting the repetition parameter.

[0249] In some embodiments, when the first information includes time domain resource information, load control information, and modulation and coding repetition transmission information, the above S230 may specifically include:

[0250] The first device determines the time length available for the first transmission based on the time domain resource information, and determines the load set or load range corresponding to the first transmission based on the time length available for the first transmission, the load control information and the modulation and coding repetition transmission information.

[0251] Exemplarily, the time domain resource information includes the maximum time length that the first device can occupy for transmission. The first device determines the maximum load based on the maximum time length, and can determine the supportable load size based on the maximum load and the load adjustment information. Alternatively, the time domain resource information includes the minimum time length that the first device can occupy for transmission. The first device determines the minimum load based on the minimum time length, and can determine the supportable load size based on the minimum load and the load adjustment information. Alternatively, the time domain resource information includes a reference time length that the first device can occupy for transmission. The first device determines a reference load based on the reference time length, and can increase or decrease the load based on the reference load and the load adjustment information.

[0252] Exemplarily, the number of different load sizes that can be supported and the reference load determine the load set. Specifically, for example, half of the number of different load sizes that can be supported minus 1 is a load smaller than the reference load, and the other half is a load larger than the reference load.

[0253] Exemplarily, the first device determines a payload set available for transmission by the first device based on a unique time length L indicated by the second device as available for transmission by the first device and a set of modulation, coding, and repeated transmission parameters or a set of modulation, coding, and repeated transmission parameters and an adjustment parameter. The parameters of the modulation, coding, and repeated transmission include at least one of modulation, coding rate, and number of repeated transmissions. The set of modulation, coding, and repeated transmission parameters includes multiple modulation, coding, and repeated transmission parameter values.

[0254] Exemplarily, the second device provides a modulation, coding, and repetition (MCR) parameter and an adjustment parameter. The first device determines a set of available payloads based on the time length L, the MCR parameter, and the adjustment parameter. For example, the MCR parameter is code rate rate1, the adjustment parameter is the code rate adjustment parameter, and the scaling factor = 1, 2, 3, or 4. The available code rates are rate1, 2*rate1, 3*rate1, and 4*rate1. The first device determines four possible payloads based on the time length L and the four code rates.

[0255] In some embodiments, after S230, the first device may further include: transmitting load indication information to the second device in the first transmission, wherein the load indication information is used to indicate the load of the first transmission, and the load of the first transmission belongs to the load set or load range corresponding to the first transmission. In this embodiment, for variable loads, the first device may carry the load indication information in the transmission, so that the second device can obtain the transmission load selected by the first device, reducing the reception complexity of the second device.

[0256] In some embodiments, the load indication information is carried by at least one of the following: uplink control information (UCI), a first signal; wherein the first signal includes at least one of the following: a preamble, a delimiter, a terminator, and a gap GAP.

[0257] Exemplarily, the first device needs to inform the second device of the payload size of the first device's transmission. The first device sends load indication information in the first device's transmission to inform the second device of the payload size of the first device's transmission. The load indication information can be carried by at least one of uplink control information (UCI), a specific sequence (e.g., a different preamble sequence, or a different reference signal sequence), or a specific terminator.

[0258] In some embodiments, in the first transmission, the UCI or the first signal precedes the data portion.

[0259] In this embodiment, the UCI or the first signal is sent before the data (load) part, and the second device receives the load indication information before receiving the data (load) part to determine the load actually occupied by the first device, so that the time domain resources not used by the first device can be promptly allocated to other devices or used for NR transmission.

[0260] Exemplarily, a cyclic redundancy check (CRC) is added to the UCI and the data part respectively.

[0261] Exemplarily, the UCI and the data portion are encoded separately.

[0262] Exemplarily, the UCI and the data parts are sent repeatedly respectively. For example, after the UCI is sent repeatedly R1 times, the data is sent again, and the data is sent repeatedly R2 times.

[0263] In some embodiments, the load indication information is also used to indicate at least one of the following: time length information corresponding to the first transmission, load size information corresponding to the first transmission, modulation coding repetition transmission parameters corresponding to the first transmission, the waveform corresponding to the first transmission, the modulation coding method corresponding to the first transmission, the power level corresponding to the first transmission, and the scheduling method corresponding to the first transmission.

[0264] Exemplarily, the second device determines the end position of the first device's transmission based on the position of the received specific terminator. The second device can continue receiving until the specific terminator is received to determine the end position of the first device's transmission. Generally, the overhead of the specific terminator is less than that of the UCI or the specific sequence. Optionally, the specific terminator is sent after the data (payload) part. Optionally, the specific terminator can be sent in the middle or before the data (payload) part. For example, the first device transmission includes a preamble and a data part. One or more preambles are included in a transmission, and the relative time position of the preamble and the data is determined. The second device determines the end position of the first device's transmission based on the last detected preamble. Taking Figure 8 as an example, a transmission of the first device may include one or more parts. In each part, the preamble occupies the time resource with a length of L1 at the beginning, and the data occupies the time resource with a length of L2 at the remaining time. The second device detects the first preamble and determines the first part of the data transmission. The second device detects the second preamble and determines the second part of the data transmission. The second device does not detect the third preamble, so the control node determines that this transmission ends at the end position of the second part.

[0265] Exemplarily, the load indication information may indicate the duration of the current transmission by the first device.

[0266] For example, the load indication information indicates the number of available time lengths for the current transmission of the first device. For example, if the number of available time lengths is 4, the load indication information includes 2 bits, indicating one of the four available time lengths. Optionally, the order of the available time lengths and the size of the indicated bit values ​​are predefined or configured. For example, the order of the load indication information bits from small to large corresponds to the order of the time lengths from small to large.

[0267] For example, the load indication information indicates the time length value of the current transmission of the first device, such as 3 bits indicating 1 to 8 time slots. The time length is the time length of the data part, or the time length is from the end point of the load indication information to the end point of the transmission. For example, the total transmission length of the first device is 10 time slots, and the transmission of the first device includes a preamble of 1 time slot, a load indication information of 1 time slot and a data part of 8 time slots. Then, the time length indicated by the load indication information is 8 time slots. Alternatively, the time length is the total length of the transmission of the first device, so the time length indicated by the load indication information is 10 time slots.

[0268] Exemplarily, the second device determines the payload size of the transmission of the first device based on the time length indicated by the load indication information of the first device. For example, based on the indicated time length and the modulation and / or coding information provided by the second device, the payload size of the transmission of the first device is calculated and / or obtained by table lookup.

[0269] Exemplarily, the load indication information indicates the load size information of the current transmission by the first device.

[0270] For example, the load indication information indicates the number of available loads for the current transmission by the first device. For example, if the number of available loads is 4, the load indication information includes 2 bits, indicating one of the four load types. The order of the load sizes and the size of the indicated bit values ​​are predefined or configured. For example, the order of the load indication information bits from small to large corresponds to the order of the loads from small to large.

[0271] For example, the load indication information indicates the load size of the current transmission by the first device, for example, an index corresponding to the load size (an index in a load table configured or predefined by the second device for the first device).

[0272] Exemplarily, the load indication information indicates the modulation, coding and repetition parameters of the current transmission by the first device. The modulation, coding and repetition parameters include at least one parameter of modulation, coding rate, and number of repetitions.

[0273] For example, the second device determines the payload size transmitted by the first device based on the modulation, coding, and repetition parameters indicated by the load indication information of the first device and the unique time length indicated by the control node. For example, the payload size transmitted by the first device is obtained by calculation and / or table lookup based on the unique time length indicated by the second device and the modulation and / or coding information indicated by the load indication information.

[0274] Exemplarily, the load indication information indicates other information that can be used to determine the load size. For example, assuming that different waveforms correspond to different loads, the load information indicates the waveform used for transmission by the first device, so that the second device can know the load corresponding to the waveform.

[0275] Exemplarily, the second device configures / instructs the first device which load indication information mode to use. Alternatively, the second device may determine which load indication information mode to use for the first device based on the type of the first device.

[0276] For example, the second device may determine information about the load selected by the first device for transmission by the first device based on predefined rules or through blind detection. In this case, the first device does not need to send load indication information. For example, the second device may blindly detect the modulation mode to determine the load transmitted by the first device.

[0277] In some embodiments, for a scenario where the second device cannot determine the size of the load to be transmitted by the first device, the first device may also send a first part of the load based on the unique time length or load size indicated by the second device, and indicate in the load how much load is left to be transmitted.

[0278] In some embodiments, the first device may report its expected load, for example, proactively or based on a trigger from the second device, such as a buffer status report. Alternatively, the first device may report expected additional resources. For example, based on the bit rate of the first device currently scheduled by the second device, the first device calculates the time-frequency resources required for the load to be transmitted, allowing the second device to obtain the first device's expected load. Based on the first device's report, the second device may allocate appropriate resources to the first device. The report may be sent before the first device begins transmitting or during the first device's transmission. For example, assuming the first device expects a load of 1, the first device sends a buffer status report to report the expected load. Based on the buffer status report, the second device may allocate appropriate resources to the first device to transmit the expected load. For another example, assuming the first device expects a load of 1 and the second device schedules a load of 2 (load 2 < load 1), the first device transmits based on load 2 and indicates the expected remaining load to be transmitted in this transmission. The second device may reschedule the first device's transmission. In this method, the load of each transmission of the first device is uniquely determined, as determined by the second device's indication. It is worth noting that the second device is not required to allocate resources according to the load expected by the first device after receiving the buffer status report.

[0279] In some embodiments, before the above S230, the method further includes: the first device determines to use a variable load method to determine a load set or a load range corresponding to the first transmission.

[0280] Exemplarily, the first device may determine the load set or load range corresponding to the first transmission using a fixed load method, or the first device may determine the load set or load range corresponding to the first transmission using a variable load method.

[0281] It should be noted that supporting fixed loads and variable loads may require different capabilities for the first device, different capabilities for the second device, different resource efficiency, and different suitable deployment environments (for example, if the first device is an A-IoT device, whether the A-IoT system is deployed in the NR carrier with the NR system).

[0282] In this embodiment, the first device may adopt a fixed load method or a variable load method to determine the load set or load range corresponding to the first transmission, and may flexibly select a load determination method based on different needs.

[0283] In some embodiments, the first device determines to use a variable load mode based on at least one of the following:

[0284] whether the first device supports variable load or fixed load, whether the second device supports variable load or fixed load, service types supported by the first device, service types corresponding to transmissions of the first device, device type of the first device, waveforms supported by the first device, waveforms corresponding to transmissions of the first device, modulation and coding schemes supported by the first device, modulation and coding schemes corresponding to transmissions of the first device, power levels supported by the first device, power levels corresponding to transmissions of the first device, load required for transmissions of the first device, channel quality measured by the first device, type of control information used for scheduling transmissions of the first device, format of control information used for scheduling transmissions of the first device, sequence of control information used for scheduling transmissions of the first device, value of at least one information field in the control information used for scheduling transmissions of the first device, scheduling scheme corresponding to transmissions of the first device, RRC state of the first device, configuration or indication of the second device, capability report of the first device, information about the radio access technology (RAT) system associated with the first device, whether the operating frequency band of the first device is licensed spectrum, bandwidth or bandwidth combination configured for the first device, and deployment scenario corresponding to the first device;

[0285] Among them, the RAT system associated with the first device is different from the RAT system accessed by the first device, and the relevant information of the RAT system associated with the first device includes at least one of the following: bandwidth size, subcarrier spacing, the interval between the bandwidth of the RAT system used for access by the first device and the bandwidth of the RAT system associated with the first device within the bandwidth of the RAT system associated with the first device, the time unit length of the RAT system associated with the first device, and whether the working frequency band of the RAT system associated with the first device is an authorized spectrum.

[0286] In this embodiment, the first device can determine the load mode used for transmission from a fixed load mode and a variable load mode, can determine the load mode used for transmission based on one or more factors, and can determine the load mode used for transmission more accurately.

[0287] Exemplarily, the first device is an A-IoT device, the RAT system accessed by the first device may be an A-IoT system, and the RAT system associated with the first device may be an NR system.

[0288] In some embodiments, the second device determines whether to support a variable load or a fixed load based on at least one of the following:

[0289] The variable load capacity of the first device is reported, and the device type of the first device.

[0290] Exemplarily, the first device directly or indirectly indicates the variable load capability of the first device through a random access uplink message (msg1 or msg3).

[0291] Exemplarily, the first device determines whether it supports variable load capability based on other capabilities of the first device, such as whether the first device supports certain power levels, modulation modes, or waveforms.

[0292] Exemplarily, the variable load capability of the first device depends on the device type of the first device. For example, a first device of type C (active device) supports a variable load, while a first device of type A / B (passive device) supports a fixed load.

[0293] In some embodiments, part or all of the information used to determine the variable load mode is applicable to a specific transmission, or part or all of the information used to determine the variable load mode is applicable to transmission in at least two modes.

[0294] In some embodiments, the specific transmission includes but is not limited to at least one of the following: uplink transmission in random access (such as msg1 or msg3 in four-step random access, or msgA in two-step random access), configured grant (CG) transmission.

[0295] Exemplarily, when CG resources are configured, the first device determines to adopt a variable load mode. For example, when CG resources are configured, the first device may determine to adopt a variable load mode based on part or all of the above information.

[0296] Exemplarily, in a random access scenario, the first device determines to adopt a variable load mode. For example, in a random access scenario, the first device may determine to adopt a variable load mode based on part or all of the above information.

[0297] In some embodiments, the second device may instruct to use a variable load method to determine a load set or load range corresponding to the transmission of the first device.

[0298] For example, a system message or device-specific signaling indication or physical layer signaling indication uses a variable load method to determine a load set or load range corresponding to the transmission of the first device. The first device can use the variable load function only if the second device indicates that it supports the variable load capability.

[0299] In some embodiments, before the second device sends the first information to the first device, the second device sends second information to the first device, wherein the second information is used to indicate that a load set or load range corresponding to the transmission of the first device is determined using a variable load method. Optionally, the second information applies to a specific transmission, or the second information applies to transmission in at least two modes. Exemplarily, the specific transmission includes at least one of the following: uplink transmission in random access, and configuration authorization CG transmission.

[0300] Exemplarily, the operating frequency band of the RAT system associated with the first device is an unlicensed spectrum. Considering the Listen Before Talk (LBT) operation, it is sometimes preferred to use a fixed time unit for a transmission, thereby adopting a fixed load method to determine the load set or load range corresponding to the transmission of the first device.

[0301] Exemplarily, the operating frequency band of the first device is an unlicensed spectrum. Considering LBT operation, it is sometimes preferred to use a fixed time unit for a transmission, thereby adopting a fixed load method to determine the load set or load range corresponding to the transmission of the first device.

[0302] Exemplarily, the bandwidth or bandwidth combination configured for the first device is A, and a fixed load method is used to determine the load set or load range corresponding to the transmission of the first device; or, the bandwidth or bandwidth combination configured for the first device is B, and a variable load method is used to determine the load set or load range corresponding to the transmission of the first device.

[0303] Exemplarily, the deployment scenario corresponding to the first device is in-band deployment (such as the RAT system accessed by the first device and the RAT system associated with the first device coexist in a frequency band, carrier or cell, and a variable load method is used to determine the load set or load range corresponding to the transmission of the first device; or, the deployment scenario corresponding to the first device is out-of-band deployment, and a fixed load method is used to determine the load set or load range corresponding to the transmission of the first device. Alternatively, the deployment scenario corresponding to the first device is in-band deployment (such as the RAT system accessed by the first device and the RAT system associated with the first device coexist in a frequency band, carrier or cell, and a fixed load method is used to determine the load set or load range corresponding to the transmission of the first device; or, the deployment scenario corresponding to the first device is out-of-band deployment, and a variable load method is used to determine the load set or load range corresponding to the transmission of the first device.

[0304] Exemplarily, the first device determines the load method based on the waveform or modulation method used by the first device for transmission. For example, if an OFDM waveform is used, the first device determines the load using a variable load method; if an OOK / ASK waveform is used, the first device determines the load using a fixed load method. For another example, if transmission uses OFDM-based OOK, the AIOT device determines the load using a variable load method; if non-OFDM OOK is used, the AIOT device determines the load using a fixed load method.

[0305] For example, assuming there are two payloads, if an OFDM waveform is used, the first device uses the first payload; if an OOK / ASK waveform is used, the first device uses the second payload.

[0306] Exemplarily, the first device determines the load mode to be adopted based on a predefined or configured load threshold and the load required for transmission by the first device. For example, when the load required for transmission by the first device is greater than or not less than a certain load threshold, the first device adopts a variable load mode to determine the load; when the load required for transmission by the first device does not exceed or is less than a certain load threshold, the first device adopts a fixed load mode to determine the load. For another example, when the load required for transmission by the first device is greater than or not less than a certain load threshold, the first device adopts a fixed load mode to determine the load; when the load required for transmission by the first device does not exceed or is less than a certain load threshold, the first device adopts a variable load mode to determine the load.

[0307] Exemplarily, the first device determines the load mode to be used based on a predefined or configured channel quality threshold and the measured channel quality. For example, when the RSRP or CSI is greater than or not less than a certain channel quality threshold, the first device determines the load using a variable load mode; when the RSRP or CSI does not exceed or is less than a certain channel quality threshold, the first device determines the load using a fixed load mode. For another example, when the RSRP or CSI is greater than or not less than a certain channel quality threshold, the first device determines the load using a fixed load mode; when the RSRP or CSI does not exceed or is less than a certain channel quality threshold, the first device determines the load using a variable load mode.

[0308] Exemplarily, the first device determines a load method or a specific load in a load set based on the type of control information sent by the second device. Transmissions scheduled by the first type of control information use a variable load method to determine a load or a specific load, while transmissions scheduled by the second type of control information use a fixed load method to determine a load or another load. For example, if the second type of control information is a control command to perform a read operation on the first device, the transmission by the first device may use a fixed load method to determine a load or determine to use the second of the two loads.

[0309] Exemplarily, the first device determines the load determination method or the load itself according to the format of the control information sent by the second device. For example, the first format of the control information corresponds to the variable load determination method, and the second format of the control information corresponds to the fixed load determination method.

[0310] Exemplarily, the first device determines the payload determination method or the payload itself based on a sequence of control information sent by the second device. For example, the scrambling sequence of the CRC of the control information, the scrambling sequence of the payload portion of the control information, or the preamble sequence of the control information. For example, sequence 1 of the control information corresponds to a variable payload determination method, and sequence 2 of the control information corresponds to a fixed payload determination method.

[0311] Exemplarily, the first device determines the load mode or load based on a value of a specific information field in the control information sent by the second device. The specific information field is at least one of the following: an information field indicating time resources, an information field indicating load, and an information field indicating modulation coding or indicating a coding method.

[0312] For example, the control information includes an information field indicating time resources. If this information field indicates a specific time length (for example, the time slot length is 0), it means that the load is determined according to a fixed load method, otherwise the load is determined according to a variable load method. Alternatively, if the value of this information field is a specific value (for example, there are 4 possible values ​​of the information field, 1, 2, 3, 4, where 1, 2, 3 indicate that the time length of the AIOT transmission is L1, L2, L3, and 4 indicates that the length of the transmission of the first device is variable. For another example, 1, 2, 3 indicate that the time length of the transmission of the first device is L1, L2, L3, and 4 indicates that the length of the transmission of the first device is variable and the maximum length is L4), taking the specific value '4' as an example, it means that the load is determined according to a variable load method, otherwise the load is determined according to a fixed load method.

[0313] For another example, the control information includes an information field indicating the load. If the value of this information field is a specific value (for example, the information field has four possible values, 1, 2, 3, and 4, where 1, 2, and 3 indicate that the load size of the transmission of the first device is S1, S2, and S3, and 4 indicates that the load of the transmission of the first device is variable. For another example, 1 and 2 indicate that the load size of the AIOT transmission is S1 and S2, 3 indicates that the load of the transmission of the first device is variable and the maximum load is S3, and 4 indicates that the load of the AIOT transmission is variable and the maximum load is S4), taking the specific values ​​'3' and '4' as examples, it means that the load is determined according to the variable load method, otherwise the load is determined according to the fixed load method.

[0314] For another example, the control information includes an information field indicating the encoding method. If the value of this information field is a specific value, it means that the load is determined according to the variable load mode, otherwise the load is determined according to the fixed load mode.

[0315] For another example, the control information includes an information field indicating the payload and encoding method. If the value of this information field is a specific value, it indicates that the payload is determined according to the variable payload method; otherwise, it is determined according to the fixed payload method. As shown in Table 2, if the MCS indicates index = 4, it indicates that the payload is determined according to the variable payload method; otherwise, it is determined according to the fixed payload method.

[0316] Table 2

[0317] Exemplarily, the second device semi-statically configures the first device to determine the load mode or load, or semi-statically + dynamically configures the first device to determine the load mode or load using signaling. For example, the default load determination mode of the first device is a fixed load mode. If the control node configures a variable load mode through Radio Resource Control (RRC) signaling, the first device can determine the load according to the variable load mode after the RRC signaling takes effect. For another example, the second device configures the available fixed load mode and variable load mode through RRC configuration or Media Access Control (MAC) signaling, and the second device activates the variable load mode through MAC signaling or physical layer signaling. The first device can determine the load according to the variable load mode after the MAC signaling or physical layer signaling takes effect.

[0318] Specifically, the configuration is only applicable to a specific uplink transmission scheduling mode. For example, it is only applicable to a configured grant. For another example, for uplink transmission with a configured grant, the second device configures uplink transmission parameters, and the parameters include information for a variable load. Only then does the uplink transmission adopt a variable load mode.

[0319] Specifically, the configuration is applicable to multiple uplink transmission scheduling modes.

[0320] Specifically, the configuration explicitly / implicitly indicates which uplink transmission scheduling mode is applicable.

[0321] Exemplarily, the variable load mode is only applicable to connected A-IoT transmission.

[0322] Exemplarily, the variable load mode is applicable to transmission in a connected state and transmission in a disconnected state / inactive state.

[0323] Exemplarily, if the device type of a first device or the configuration of a second device only supports one method of determining the load, the first device can determine the method of the load. For example, the first device reports that the capability only supports a fixed load method, or the second device indicates through system information that it only supports a fixed load method, then the first device can determine the load in a fixed load method only. If the device type of a first device and the configuration of the second device support two methods of determining the load, the first device determines whether to use a fixed load method or a variable load method to determine the load based on at least one other implementation method above (other methods except the method of determining the load based on the device type). For example, if the first device capability supports fixed load and variable load, and the second device indicates that it supports fixed load and variable load through system information, then the first device determines whether to use a fixed load method or a variable load method to determine the load of a transmission based on at least one other implementation method above (other methods except the method of determining the load based on the device type).

[0324] Therefore, in an embodiment of the present application, the first device can determine the load set or load range corresponding to the first transmission based on the time domain resource information corresponding to the first transmission, the load control information corresponding to the first transmission, or the modulation and coding repetition transmission information corresponding to the first transmission obtained from the second device, and select the load of the first transmission from the load set or load range corresponding to the first transmission. Thus, the first device can independently select the load corresponding to the transmission within the controllable range of the second device (controllable load set or load range), which can reduce the reception complexity of the second device and improve resource utilization.

[0325] The load determination method provided in the embodiments of the present application may be executed by a load determination device or a processing unit in the load determination device for executing the load determination method. The embodiments of the present application take the load determination device executing the load determination method as an example to illustrate the load determination device provided in the embodiments of the present application.
