[0037] The following, in conjunction with the accompanying drawings, describes in detail the transmission parameter determination method, apparatus, terminal, network-side equipment, and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0038] Currently, uplink capacity enhancement in the protocol mainly considers using OCC to improve the data capacity of the Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing Physical Uplink Shared CHannel (DFT-s-OFDM PUSCH), without enhancing the demodulation reference signal (DMRS).

[0039] In order to improve the terminal multiplexing capability and increase the system capacity, an OCC-based block-wise spreading transmission method is introduced in Physical Uplink Control Channel (PUCCH) transmission.

[0040] Among them, for PUCCH format 3, block-wise spreading transmission is supported only in the case of interlace mapping, and multiplexing of 1 / 2 / 4 terminals (also called users) is supported only when single interlace is configured; for PUCCH format 4, multiplexing of 2 / 4 terminals is supported, which is configured through the high-level parameter occ-Length.

[0041] From the block-wise spreading provisions in the current agreement, we can see that:

[0042] 1. The addition of block-wise spreading is reflected in the frequency domain. For the time domain, the OCC sequence (w_n) multiplied by each symbol is the same;

[0043] 2. By It can be seen that:

[0044] Satisfy in frequency domain These consecutive subcarriers are multiplied by are the same, that is, these consecutive subcarriers can be understood as a block (i.e., block);

[0045] 3. The above blocks are divided according to the total number of subcarriers corresponding to the transmission bandwidth allocated to the uplink channel. That is, the number of blocks is equal to the total number of subcarriers divided by the number of multiplexed terminals.

[0046] 4. The maximum number of multiplexed terminals is 4;

[0047] 5. Only terminals allocated with the same resource block (RB) can be multiplexed together.

[0048] In addition, for block-wise spreading, different terminals are multiplied by different OCC sequences. Then, the transformation characteristics of the Fast Fourier Transform (FFT) are utilized so that different terminals occupy different REs during frequency domain mapping after pre-DFT transformation. For example, terminal 0 occupies odd-numbered REs and terminal 1 occupies even-numbered REs. This achieves a comb mapping effect and enables multiple terminals to be multiplexed.

[0049] For example, assuming that terminal 1, terminal 2, terminal 3 and terminal 4 are multiplexed and the bandwidth allocated to each terminal is 2 RBs, then Figure 2 shows the changes of terminal 1 before and after pre-DFT, Figure 3 shows the changes of terminal 2 before and after pre-DFT, Figure 4 shows the changes of terminal 3 before and after pre-DFT, and Figure 5 shows the changes of terminal 4 before and after pre-DFT; it can be seen that after the pre-DFT transformation, the four terminals occupy different REs during frequency domain mapping.

[0050] Currently, the PUSCH transport block size (TBS) is calculated based on the following parameters:

[0051] Available resources: the number of allocated time-domain symbols and the number of frequency-domain physical resource blocks (PRBs);

[0052] Modulation order Q corresponding to the modulation and coding strategy (MCS) level m , target bit rate R;

[0053] Number of layers υ.

[0054] The specific calculation process of PUSCH TBS is as follows:

[0055] Step 1: Calculate the number of available REs;

[0056] 1. Calculate the number of REs available in a PRB: in, Indicates that a PRB in the frequency domain contains 12 subcarriers; is the number of PUSCH symbols scheduled in a time slot; The overhead of DMRS in one PRB; It is configured by the xOverhead field in the high-level parameter PUSCH-ServingCellConfig, taking into account the overhead of the Channel State Information-Reference Signal (CSI-RS) and the control resource set (CORESET). The default value is 0 and the configurable value is {6, 12, 18}. For Msg3 (i.e., message 3) PUSCH transmission, Set to 0.

[0057] 2. Calculate the total number of REs available for configured PUSCH transmission: N RE =min(156,N' RE)·n PRB , where n PRB is the number of PRBs allocated to the terminal.

[0058] Step 2: Calculate the number of intermediate information bits: N info =N RE ·R·Q m ·υ;

[0059] Among them, when N info If ≤3824, use step 3; otherwise, use step 4.

[0060] Step 3: N info ≤3824:

[0061] 1. Quantify the number of intermediate information bits in

[0062] 2. Find the value not less than N' in Table 5.1.3.2-1. info The latest TBS.

[0063] Step 4: N info >3824:

[0064] 1. Quantify the intermediate number in,

[0065] 2. If the target bit rate R≤1 / 4, then:

[0066] in

[0067] 3. If the target bit rate R>1 / 4, then:

[0068] If N' info >8424, in

[0069] otherwise,

[0070] For the narrowband physical uplink shared channel (Narrowband PUSCH, NPUSCH), the determination of the TBS mainly depends on the corresponding parameters to determine I_TBS, so that the corresponding TBS can be found by referring to the TBS table.

[0071] As can be seen from the above, most scenarios currently support only single-layer transmission, and DMRS ports already support multi-port multiplexing. However, when the network coverage area is large, the number of terminals accessing at the same time may be relatively large. In order to increase system capacity and enhance the uplink transmission multiplexing capability, the data part of the uplink channel needs to be enhanced to increase capacity. For example, a block-wise spreading transmission method similar to PUCCH format 4 can be used to achieve multi-terminal multiplexing based on OCC.

[0072] However, since uplink transmission is performed based on OCC, compared with single-user uplink transmission not performed based on OCC, the same time-frequency resources will transmit fewer bits or map fewer complex-valued symbols. Therefore, how to accurately determine the transmission parameters when performing uplink transmission based on OCC has become an urgent problem that needs to be solved.

[0073] To address the above issues, embodiments of the present application provide a method, apparatus, terminal, network-side device, and medium for determining transmission parameters. The transmission parameter determination method provided in embodiments of the present application can be applied to determining uplink transmission parameters in non-terrestrial network (NTN) scenarios or terrestrial network (TN) scenarios.

[0074] In the transmission parameter determination method provided in an embodiment of the present application, a terminal can determine the transmission parameters of a first uplink transmission based on first information; wherein the first information includes at least one of the following: enabling information, the enabling information being used to enable or disable the terminal from performing the first uplink transmission based on the OCC; and OCC information, the OCC information being the OCC information used for the first uplink transmission. Through this solution, since the terminal can determine the transmission parameters of the first uplink transmission based on the enabling information for enabling or disabling the terminal from performing the first uplink transmission based on the OCC and at least one of the OCC information used for the first uplink transmission, when performing the first uplink transmission based on the OCC, the transmission parameters can be determined based on the OCC-related information, so that the determined transmission parameters match the first uplink transmission, and thus the transmission parameters when performing the uplink transmission based on the OCC can be accurately determined.

[0075] It should be noted that the transmission parameter determination method provided in the embodiment of the present application is applicable not only to the NR system, but also to the LTE narrowband Internet of Things (NB-IoT) system or IoT NTN system, etc., and the embodiment of the present application is not limited.

[0076] The embodiment of the present application provides a method for determining transmission parameters, and Figure 6 shows a flow chart of the method for determining transmission parameters provided by the embodiment of the present application. As shown in Figure 6, the method for determining transmission parameters provided by the embodiment of the present application may include the following step 601.

[0077] Step 601: The terminal determines a transmission parameter for a first uplink transmission based on first information.

[0078] The first information includes at least one of the following:

[0079] Enabling information, where the enabling information is used to enable or disable the terminal to perform the first uplink transmission based on the OCC;

[0080] OCC information, where the OCC information is the OCC information used for the first uplink transmission.

[0081] Optionally, in an embodiment of the present application, the above-mentioned first information may be obtained by the terminal from a network side device.

[0082] Optionally, in an embodiment of the present application, the first information may be carried by a high-layer parameter or downlink control information (DCI); the DCI may be a DCI for scheduling or activating the first uplink transmission.

[0083] Optionally, in an embodiment of the present application, after determining the transmission parameters of the first uplink transmission, the terminal may perform the first uplink transmission based on the OCC based on the transmission parameters.

[0084] Optionally, in an embodiment of the present application, performing the above-mentioned first uplink transmission based on OCC may include: using the OCC sequence to perform multi-terminal multiplexing uplink transmission or spread spectrum uplink transmission in the time domain or frequency domain.

[0085] Optionally, in an embodiment of the present application, when the enabling information is used to disable the terminal from performing the first uplink transmission based on the OCC, the transmission parameters of the first uplink transmission may be determined according to the current protocol behavior.

[0086] Optionally, in an embodiment of the present application, the above-mentioned OCC information may include at least one of an OCC sequence, an OCC length, and the number of multiplexed terminals.

[0087] Optionally, in an embodiment of the present application, the above-mentioned first uplink transmission may include: PUSCH, PUSCH repetition type A, PUSCH repetition type B, PUSCH multi-slot transmission block (TB over multiple slots, TBoMS), NPUSCH or NPUSCH repetition, etc.

[0088] Optionally, in an embodiment of the present application, the first uplink transmission may be an initial transmission or a retransmission.

[0089] Wherein, in the case that the first uplink transmission is a retransmission, the first information is the same as or different from the first information of the initial uplink transmission.

[0090] That is, when the first uplink transmission is a retransmission, the first information based on which the terminal determines the transmission parameters of the first uplink transmission may be the same as or different from the first information based on which the terminal determines the transmission parameters of the initial transmission of the first uplink transmission.

[0091] In an embodiment of the present application, since the above-mentioned first uplink transmission is a retransmission, the above-mentioned first information may be the same as or different from the first information when the first uplink transmission is initially transmitted. Therefore, when determining the transmission parameters of the first transmission, it may be based on the first information when initially transmitted, or it may be based on information different from the first information when initially transmitted, thereby improving the flexibility of determining the transmission parameters of the first transmission.

[0092] Optionally, in the embodiment of the present application, the transmission parameters may include at least one of the following 1.1 to 1.6:

[0093] 1.1, TBS;

[0094] 1.2. The number of transmission resources corresponding to the rate matching output;

[0095] 1.3. The number of bits corresponding to the rate matching output;

[0096] 1.4. The number of transmission resources before transmission resource mapping;

[0097] 1.5, the number of complex-valued symbols before transmission resource mapping;

[0098] 1.6. The number of complex-valued symbols transmitted in a first target block, where the first target block is a basic unit for performing the first uplink transmission based on the OCC.

[0099] It should be noted that the rate matching process is used to process bits on the transmission channel to match the carrying capacity of the physical channel. Optionally, the rate matching output may be bits that have undergone channel coding.

[0100] Optionally, in an embodiment of the present application, the target block may also be referred to as a block, a multiplexing block, a resource set, or a multiplexing resource block, etc., any name that can represent the basic unit when performing the above-mentioned first uplink transmission based on OCC. The embodiment of the present application is only an example of the first target block, and the specific name of the first target block is not limited in actual implementation.

[0101] In the embodiment of the present application, since the above-mentioned transmission parameters can include at least one of the above-mentioned 1.1 to 1.6, different transmission parameters of the above-mentioned first uplink transmission can be determined based on the above-mentioned first information, thereby further improving the flexibility of determining the transmission parameters of the first transmission.

[0102] Optionally, in an embodiment of the present application, the first information may further include first indication information, where the first indication information is used to indicate at least one of the following: the TBS (i.e., 1.1 above); a TBS index (i.e., I_TBS) offset value; and a resource unit (RU) indication (i.e., I_RU) offset value. Exemplarily, the TBS may be determined based on the first indication information.

[0103] In an embodiment of the present application, since the above-mentioned TBS can be determined based on the above-mentioned first indication information, the TBS of the first uplink transmission can be directly determined through the information included in the above-mentioned first information for indicating at least one of the TBS, TBS index offset value and RU offset value, thereby simplifying the process of determining the TBS of the first uplink transmission.

[0104] Optionally, in an embodiment of the present application, the first target block may be obtained based on the first frequency domain resources and the first time domain resources.

[0105] The first frequency domain resource includes any one of the following: at least one RE; at least one subcarrier; at least one RB; a set of RBs determined by the frequency domain resource assignment (FDRA) of the first uplink transmission;

[0106] The above-mentioned first time domain resources include any one of the following items: at least one orthogonal frequency division multiplexing (OFDM) symbol; at least one time slot; at least one repeated time domain resource; at least one RU; a time domain symbol set determined by the time domain resource allocation (TDRA) of the above-mentioned first uplink transmission.

[0107] Optionally, in an embodiment of the present application, the above-mentioned first target block may be indicated or configured by a network-side device.

[0108] Optionally, in an embodiment of the present application, the size of the first target block can be obtained by multiplying the first frequency domain resource and the first time domain resource.

[0109] Optionally, in an embodiment of the present application, when the above-mentioned at least one time slot is multiple time slots, the multiple time slots can be multiple time slots occupied by the transmission symbols of part of the repetition when NPUSCH is used for repetition transmission (i.e., the above-mentioned first uplink transmission); at this time, the multiple time slots neither belong to a repetition nor a complete RU.

[0110] Exemplarily, during NPUSCH repetition transmission, the transmission symbol on an RU is repeated; for example, the transmission symbol consists of four parts, ABCD, and each part occupies one time slot in the time domain. If a total of two repetitions are required, one possible repetition scenario is ABCDABCD, in which case the above-mentioned multiple time slots are the basic size for repetition, i.e., 4 time slots; another possible repetition scenario is ABABCDCD, in which case the above-mentioned multiple time slots are the basic size for repetition, i.e., 2 time slots.

[0111] In an embodiment of the present application, since the above-mentioned first target block can be obtained based on the above-mentioned first frequency domain resources and the above-mentioned first time domain resources, and the first frequency domain resources and the first time domain resources can both include different resources, the first target block can be obtained through different frequency domain resources and time domain resources, thereby improving the flexibility of obtaining the first target block.

[0112] Optionally, in an embodiment of the present application, the above transmission parameters may be determined based on the second object and the scaling factor.

[0113] The second object is a parameter or mapping relationship used to calculate the transmission parameter, and the scaling factor is determined based on the first information.

[0114] Optionally, in an embodiment of the present application, the above-mentioned second object can also be any possible object used in the current protocol to calculate the transmission parameters of uplink transmission, and the embodiment of the present application is not limited thereto.

[0115] Exemplarily, the terminal can first determine the scaling ratio of the above-mentioned transmission parameters through the above-mentioned OCC information, and then determine the above-mentioned scaling factor, and use the scaling factor to adjust the above-mentioned second object to obtain the first object (that is, the adjusted second object), and then determine the above-mentioned transmission parameters based on the first object.

[0116] In an embodiment of the present application, since a scaling factor determined based on the first information is used in determining the transmission parameters, the determined transmission parameters can match the first uplink transmission performed based on the OCC, thereby improving the accuracy of determining the transmission parameters of the first uplink transmission.

[0117] Optionally, in an embodiment of the present application, the transmission parameter includes a TBS. Exemplarily, the second object may include at least one of the following: the number of time domain symbols available for the first uplink transmission; the number of PRBs available for the first uplink transmission; the number of REs available for the first uplink transmission; the number of intermediate information bits; the first TBS; the number of RUs available for the first uplink transmission; and a TBS determined based on a TBS index and an RU indication.

[0118] Optionally, in the embodiment of the present application, the first TBS may be a TBS for the first uplink transmission determined by a current protocol behavior, that is, the TBS for the first uplink transmission is determined by a TBS determination process of the current protocol.

[0119] Optionally, in an embodiment of the present application, when the above-mentioned second object is the TBS determined based on the TBS index and RU indication, the process of determining the TBS of the above-mentioned first uplink transmission is as follows: first use the above-mentioned scaling factor to adjust the TBS determined by looking up the TBS index and RU indication table TS36.211Table 16.5.1.2-2, and then round the TBS (for example, round up, round down, round up or round to 0, etc.), and then find a TBS in the table that is closest to the scaled and rounded value (which can be greater than and closest, or less than and closest), and determine it as the TBS of the first uplink transmission.

[0120] Optionally, in an embodiment of the present application, when the above-mentioned second object is the number of RUs available for the above-mentioned first uplink transmission, the process of determining the TBS of the above-mentioned first uplink transmission is as follows: first use the above-mentioned scaling factor to adjust the number of RUs to update the RU indication, and then look up table TS36.211Table 16.5.1.2-2 through the TBS index and the updated RU indication to determine the TBS of the first uplink transmission.

[0121] The following is an illustrative description of a specific method for the terminal to determine the TBS for the first uplink transmission.

[0122] Exemplarily, taking the first uplink transmission as PUSCH and the scaling factor as β as an example, then:

[0123] (1) When the second object includes the number of time-domain symbols available for the first uplink transmission, the process for determining the TBS of the first uplink transmission is as follows:

[0124] The above step 1 in the above related technology:

[0125] 1. Calculate the number of REs available in a PRB: in, is the number of symbols scheduled for uplink transmission in a time slot;

[0126] 2. Calculate the total number of REs available for configured PUSCH transmission: N RE =min(156,N' RE )·n PRB , where n PRB is the number of PRBs allocated to the UE;

[0127] The subsequent calculation process is the same as steps 2 / 3 / 4 in the above related technology.

[0128] (2) When the second object includes the number of PRBs available for the first uplink transmission, the process for determining the TBS of the first uplink transmission is as follows:

[0129] The above step 1 in the above related technology:

[0130] (1) Calculate the number of available REs in a PRB:

[0131] (2) Calculate the total number of REs available for configured PUSCH transmission: N RE =min(156,N' RE )·n' PRB , n' PRB =n PRB β, where n PRB is the number of PRBs allocated to the terminal (i.e., the number of PRBs determined by FDRA);

[0132] The subsequent calculation process is the same as steps 2 / 3 / 4 in the above related technology.

[0133] (3) When the second object includes the number of REs available for the first uplink transmission, the process for determining the TBS of the first uplink transmission is as follows:

[0134] The above step 1 in the above related technology:

[0135] (1) Calculate the number of available REs in a PRB:

[0136] (2) Calculate the total number of REs available for configured PUSCH transmission: N RE =β·min(156,N' RE )·n PRB , where n PRB is the number of PRBs allocated to the terminal;

[0137] The subsequent calculation process is the same as steps 2 / 3 / 4 in the above related technology.

[0138] (4) When the second object includes the number of intermediate information bits, the process for determining the TBS of the first uplink transmission is as follows:

[0139] Step 1 in the above related art: Calculate the number of available REs

[0140] (1) Calculate the number of available REs in a PRB:

[0141] (2) Calculate the total number of REs available for configured PUSCH transmission: N RE =min(156,N' RE )·n PRB , where n PRB is the number of PRBs allocated to the terminal;

[0142] Step 2 in the above related technology: Calculate the number of intermediate information bits: N info =INT((N RE ·R·Q m ·υ)·β)

[0143] (1) When N info When ≤3824, use step 3 in the above related technology;

[0144] (2) Otherwise, adopt the above step 4 in the above related technology;

[0145] The subsequent calculation process is the same as steps 3 / 4 in the above-mentioned related technology.

[0146] (5) When the second object includes the first TBS, the process of determining the TBS of the first uplink transmission is as follows:

[0147] According to the above steps 1 / 2 and 3 / 4 in the above related technology, TBS is obtained: NTBS , and the TBS of the first uplink transmission is N' TBS =INT(N TBS β);

[0148] Wherein, INT(·) represents a rounding function, which includes at least one of the following: rounding up, rounding down, rounding to the nearest integer, and rounding toward zero. Of course, if the TBS scaling factor β always results in an integer or β=1 for a calculation formula containing β, the rounding function INT(·) may not exist for that calculation formula.

[0149] As another example, taking the first uplink transmission as NPUSCH as an example, the TBS of the NPUSCH can be determined by at least one of the following A and B:

[0150] A. Obtain the initial TBS by looking up the table TS36.211 Table 16.5.1.2-2 using the TBS index (I_TBS) and RU indication (I_RU). Scale the initial TBS by the above scaling factor, then round it up, round it down, round it off, or round it to 0. Then, find the TBS that is greater than and closest to the value in Table 16.5.1.2-2 of 3GPP TS36.211, or find the TBS that is less than and closest to the value, and determine it as the TBS of the NPUSCH.

[0151] B. Scale the available RU number by the scaling factor to update the RU indication (I_RU), and then query 3GPP TS 36.211 Table 16.5.1.2-2 using the TBS index (I_TBS) and the updated RU indication (I_RU) to obtain the TBS of the NPUSCH.

[0152] Optionally, in an embodiment of the present application, when the above-mentioned first uplink transmission is a repetition transmission, the above-mentioned method for determining TBS is also applicable. For example, for repetition transmission in the NR system, the TBS is determined per repetition, that is, the TBS size determined for each repetition is the same, and a repetition is a symbol set determined in the time domain according to TDRA; wherein, a PUSCH repetition type A repetition is per slot, that is, even if the symbol set does not occupy a full slot, the remaining unscheduled symbols are not used, and the next repetition starts from the next slot; PUSCH repetition type B is mini-slot, that is, the symbol set may not occupy a full slot, and the remaining unscheduled symbols can be used for other repetitions, for example, the next repetition starts after the last symbol of the symbol set.

[0153] Optionally, in an embodiment of the present application, when scaling the number of transmission resources corresponding to the rate matching output of the first uplink transmission based on the OCC length / number of multiplexed terminals, the scaling factor may be determined by the OCC length or the number of multiplexed terminals; for example, scaling factor = 1 / number of multiplexed terminals, or scaling factor = 1 / OCC length. If the enabling information in the OCC information enables the first uplink transmission based on the OCC, the number of available resources calculated based on the rate matching output needs to be multiplied by the scaling factor accordingly.

[0154] Optionally, in an embodiment of the present application, when scaling the number of complex-valued symbols available for mapping in the first uplink transmission based on the OCC length / number of multiplexed terminals, the scaling factor may be determined by the OCC length or the number of multiplexed terminals; for example, scaling factor = 1 / number of multiplexed terminals, or scaling factor = 1 / OCC length. If the enabling information in the OCC information enables the first uplink transmission based on the OCC, the total number of complex-valued symbols available for mapping needs to be multiplied by the scaling factor accordingly.

[0155] In an embodiment of the present application, since when determining the TBS of the above-mentioned first uplink transmission, the above-mentioned scaling factor can be used to adjust at least one of the number of time domain symbols available for the above-mentioned first uplink transmission, the number of available PRBs, the number of available REs, the number of intermediate information bits, the first TBS, the number of available RUs and the TBS determined based on the TBS index and the RU indication, the TBS of the first uplink transmission can be determined by adjusting different second objects, thereby improving the flexibility of determining the TBS of the first uplink transmission.

[0156] Optionally, in the embodiment of the present application, the OCC information may include at least one of an OCC length and a number of multiplexed terminals, and the scaling factor may be determined based on at least one of the OCC length and the number of multiplexed terminals.

[0157] or,

[0158] The first information may further include the scaling factor.

[0159] The number of multiplexed terminals is the number of multiplexable terminals, and the number of multiplexed terminals is used to indicate the multiplexing capability of the OCC.

[0160] Optionally, in an embodiment of the present application, when the above-mentioned scaling factor is determined based on at least one of the above-mentioned OCC length and the above-mentioned number of multiplexed terminals, if the above-mentioned transmission parameter is a transmission parameter within the above-mentioned first target block, then the OCC length and the number of multiplexed terminals refer to the OCC length and the number of multiplexed terminals within the first target block.

[0161] Optionally, in an embodiment of the present application, when the first information may further include the scaling factor, the scaling factor may be included in the OCC information.

[0162] Optionally, in an embodiment of the present application, when the above-mentioned first information can also include the above-mentioned scaling factor, if the above-mentioned first uplink transmission is a retransmission, the scaling factor included in the first information can be the same as or different from the scaling factor used when the first uplink transmission is initially transmitted.

[0163] Optionally, in an embodiment of the present application, when the scaling factor included in the above-mentioned first information is the same as the scaling factor used in the initial transmission of the above-mentioned first uplink transmission, if the terminal does not expect to use the scaling factor, the terminal can re-determine a scaling factor based on the above-mentioned OCC length and at least one of the above-mentioned number of multiplexed terminals.

[0164] In an embodiment of the present application, since the scaling factor can be determined by the terminal based on the OCC information, or can be directly included in the first information, the scaling factor can be determined in different ways, thereby improving the flexibility of determining the scaling factor.

[0165] In the transmission parameter determination method provided in the embodiment of the present application, since the terminal can determine the transmission parameters of the first uplink transmission based on the enabling information used to enable or disable the terminal to perform the first uplink transmission based on the OCC and at least one item of the OCC information used for the first uplink transmission, when the first uplink transmission is performed based on the OCC, the transmission parameters can be determined according to the information related to the OCC, so that the determined transmission parameters match the first uplink transmission, and thus the transmission parameters when the uplink transmission is performed based on the OCC can be accurately determined.
