For example, in a non-terrestrial network (NTN), the coverage of the network device is usually much larger than that of a ground system, and the number of terminals also increases significantly, resulting in a more prominent problem of limited system uplink capacity.

[0115] In order to make the purposes, technical solutions and advantages of the present disclosure clearer, the technical solutions in the present disclosure will be described clearly and completely below in conjunction with the drawings in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0116] Currently, in a new radio (NR) system, uplink transmission supports two waveforms, which are cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) and discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-s-OFDM), and the DFT-s-OFDM waveform has a lower peak to average power ratio (PAPR).

[0117] A power amplifier usually plays an important role in communication, and has two typical working states: a saturation region and a linear region. The power amplifier working in the saturation state will cause the signal to be unable to be demodulated, and in order to ensure the demodulation performance, it is necessary to back off to the linear region, and excessive back off will reduce the efficiency of the power amplifier. Therefore, the DFT-s-OFDM waveform with low PAPR has a wider application, especially in a power-limited satellite system. In the embodiments of the present disclosure, uplink transmission is implemented based on the DFT-s-OFDM waveform.

[0118] Currently, the related art supports code division multiplexing (CDM) of a physical uplink shared channel (PUSCH) demodulation reference signal (DMRS), and the PUSCH DMRS sequence r(n) supports multi-user transmission through time-frequency orthogonal code division, and is specifically as shown in the following formula (1):

[0119] wherein the sequence r(n) is mapped to an intermediate quantity according to the condition of formula (1) k=4n+2k′+Δ;k′=0,1; n=0,1,….

[0120] Based on antenna port In combination with Table 1 below, w can be determined f (k') and w t (l') are determined, and then the intermediate quantity

[0121] Table 1

[0122] The above embodiments are described for PUSCH DMRS transmission. The following describes PUSCH transmission in related technologies.

[0123] For uplink transmission of PUSCH, the maximum uplink transmission can currently support repetition 32 times. Repetition improves the link demodulation performance while causing system capacity to decline. Generally, repetition 2 times can obtain 3dB gain, while causing capacity to be halved. Single-layer and single-antenna port transmission are supported for data transmission.

[0124] The uplink transmission of PUSCH can support TboMS (TB processing over multiple slots PUSCH). TboMS is a technology that uses multiple slots to transmit a TB. TboMS can increase the number of REs, so that a lower modulation and coding mode can be used to increase the uplink coverage.

[0125] TBoMS can be configured simultaneously with PUSCH repetition transmission, or only PUSCH repetition transmission can be configured.

[0126] FIG. 1 is a schematic diagram of PUSCH repetition transmission provided by related technologies. As shown in FIG. 1, the repetition number is K, and the network device does not configure the TBoMS slot number, or the TBoMS slot number is 1. For any one of the K times of repetition transmission, a TB is transmitted through 1 slot. For example, the first repetition transmission transmits uplink through slot m, the second repetition transmission transmits uplink through slot m+1, and so on.

[0127] FIG. 2 is a schematic diagram of a TBoMS and PUSCH repetition transmission provided by the related art, as shown in FIG. 2, the repetition number is K, and the TBoMS time slot number is N (N is greater than 1). For any one of the K times of repetition transmission, one TB is transmitted through N time slots. For example, in the first repetition transmission, uplink transmission is performed through time slot m+1 to time slot m+N, in the second repetition transmission, uplink transmission is performed through time slot m+N+1 to time slot m+2N, and so on.

[0128] However, the related art currently only supports CDM of PUSCH DMRS and does not support CDM of PUSCH, resulting in limited terminals that can perform data transmission. When the number of terminals is large, the system uplink capacity is limited due to limited resources.

[0129] Based on this, the embodiment of the present disclosure provides an uplink data transmission method to improve the system uplink capacity. The scheme of the embodiment of the present disclosure is introduced below in combination with the drawings.

[0130] FIG. 3 is a flowchart of an uplink data transmission method provided by the embodiment of the present disclosure, as shown in FIG. 3, the method is applied to a first terminal and includes the following steps:

[0131] S31, receiving indication information sent by a network device, the indication information being used to indicate an OCC sequence of the first terminal, wherein the first terminal belongs to one of a plurality of terminals, and the OCC sequences of any two terminals in the plurality of terminals are in an orthogonal relationship.

[0132] OCC is a coding technology used in a communication system, and its principle is to divide the original information into multiple sub-information for coding, so that the code words formed after coding each sub-information are orthogonal to each other, thereby realizing efficient transmission and decoding.

[0133] In order to improve the system uplink capacity, the network device configures a corresponding OCC sequence for each of the plurality of terminals and indicates the OCC sequence to each terminal through indication information. The OCC sequence includes a plurality of spreading factors. For any two terminals in the plurality of terminals, the OCC sequences of the two terminals are orthogonal to each other. For the first terminal in the plurality of terminals, the network device sends indication information to the first terminal, and the indication information is used to indicate the OCC sequence of the first terminal.

[0134] S32, processing the initial uplink data based on the OCC sequence of the first terminal and the transmission configuration parameter to obtain target uplink data.

[0135] The initial uplink data is data to be sent by the first terminal. The first terminal can transmit the initial uplink data to the network device in a repeated manner, or can not transmit the initial uplink data to the network device in a repeated manner, which is not limited in the embodiments of the present disclosure. The target uplink data is data obtained by performing corresponding time domain spread spectrum processing on the initial uplink data by using the OCC sequence of the first terminal and the transmission configuration parameter.

[0136] The transmission configuration parameter is a parameter configured by the network device and related to uplink data transmission of the first terminal. The transmission configuration parameter can be used to determine the related configuration of the first terminal for uplink data transmission, such as whether to perform repeated transmission, whether to configure TBoMS, and the like.

[0137] Based on the OCC sequence of the first terminal and the transmission configuration parameter, the initial uplink data can be processed. Specifically, the transmission configuration parameter can be used to determine a plurality of pieces of sub-information of the initial uplink data, and the OCC sequence of the first terminal can be used to encode the plurality of pieces of sub-information of the initial uplink data, so as to obtain the target uplink data.

[0138] S33, the target uplink data is sent to the network device.

[0139] After obtaining the target uplink data, the first terminal sends the target uplink data to the network device. Since the target uplink data is obtained by processing the initial uplink data based on the OCC sequence of the first terminal and the transmission configuration parameter, the network device can decode the initial uplink data based on the OCC sequence of the first terminal and the transmission configuration parameter after receiving the target uplink data, so as to complete the uplink data transmission from the first terminal to the network device.

[0140] Further, since the OCC sequences of each two terminals in the plurality of terminals are orthogonal to each other, the target uplink data obtained by each terminal based on the corresponding OCC sequence and the transmission configuration parameter avoids cross interference, and realizes code division multiplexing transmission of the plurality of terminals on the uplink data.

[0141] The uplink data transmission method provided in the embodiments of the present disclosure includes that the first terminal receives indication information sent by the network device, the indication information is used to indicate the OCC sequence of the first terminal, and then the initial uplink data is processed based on the OCC sequence of the first terminal and the transmission configuration parameter to obtain the target uplink data, and the target uplink data is sent to the network device. Since the OCC sequences of each two terminals in the plurality of terminals configured by the network device are orthogonal to each other, the target uplink data obtained by processing the initial uplink data based on the OCC sequence of each terminal and the transmission configuration parameter can avoid cross interference, and can realize uplink data transmission of the plurality of terminals on the same time-frequency resource, so as to improve the capacity of the system uplink.

[0142] In a possible implementation, the indication information sent by the network device to the first terminal includes at least one of the following 1.1 to 1.3, and the network device explicitly or implicitly indicates the OCC sequence of the first terminal through the indication information.

[0143] 1.1, the OCC sequence of the first terminal.

[0144] After the network device configures the OCC sequences of the plurality of terminals respectively, the network device sends indication information to the first terminal among the plurality of terminals, and the indication information includes the OCC sequence of the first terminal. After the first terminal receives the indication information, the first terminal can obtain the OCC sequence of the first terminal.

[0145] 1.2, an OCC sequence matrix, and the OCC sequence matrix includes the OCC sequences of the plurality of terminals respectively.

[0146] After the network device configures the OCC sequences of the plurality of terminals respectively, the network device sends indication information to the first terminal among the plurality of terminals, and the indication information includes the OCC sequence matrix composed of the OCC sequences of the plurality of terminals respectively. The first terminal belongs to one of the plurality of terminals, and thus the OCC sequence matrix includes the OCC sequence of the first terminal. After the first terminal receives the indication information, the first terminal can obtain the OCC sequence matrix. Then, the first terminal determines the OCC sequence of the first terminal from the OCC sequence matrix.

[0147] 1.3, the OCC sequence index of the first terminal.

[0148] The OCC sequence index of the first terminal is used to indicate the OCC sequence of the first terminal in the OCC sequence matrix. After the network device configures the OCC sequences of the plurality of terminals respectively, the network device sends indication information to the first terminal among the plurality of terminals, and the indication information includes the OCC sequence index of the first terminal. After the first terminal receives the indication information, the first terminal can determine the OCC sequence of the first terminal in the OCC sequence matrix through the OCC sequence index of the first terminal.

[0149] In a possible implementation, the indication information can be carried through at least one of a high-layer parameter and downlink control information (DCI), and in the case of carrying the indication information through the DCI, the indication information can be carried through adding a DCI field and / or through an existing DCI field.

[0150] In combination with the above 1.1 to 1.3, the network device explicitly or implicitly indicates the OCC sequence of the first terminal through a plurality of ways, which will be introduced in combination with several specific examples.

[0151] Example 1, the indication information is carried in a high layer parameter, the indication information includes the OCC sequence of the first terminal, the network device sends the indication information to the first terminal, and the first terminal can determine the OCC sequence of the first terminal after receiving the indication information.

[0152] Example 2, the indication information is carried in DCI, the indication information includes the OCC sequence of the first terminal, the network device sends the indication information to the first terminal, and the first terminal can determine the OCC sequence of the first terminal after receiving the indication information.

[0153] Example 3, the indication information includes an OCC sequence matrix and an OCC sequence index of the first terminal, the indication information is carried in a high layer parameter and DCI, wherein the network device sends the OCC sequence matrix to the first terminal through the high layer parameter, and sends the OCC sequence index of the first terminal to the first terminal through the DCI. The first terminal determines the OCC sequence of the first terminal from the OCC sequence matrix based on the OCC sequence index of the first terminal.

[0154] Example 4, the indication information includes an OCC sequence matrix, the indication information is carried in a high layer parameter or DCI, the network device sends the OCC sequence matrix to the first terminal through the high layer parameter or DCI, and the OCC sequence index of the first terminal is indicated by the terminal identifier of the first terminal. The first terminal determines the OCC sequence index of the first terminal through the terminal identifier of the first terminal, and then determines the OCC sequence of the first terminal from the OCC sequence matrix based on the OCC sequence index of the first terminal. A possible example is that occ index = mod(ID, d), where occ index represents the OCC sequence index of the first terminal, ID represents the terminal identifier of the first terminal, d represents the number of spreading factors included in the OCC sequence of the first terminal, and mod represents the modulo operation. The value of d may be equal to the number of repetitions of the initial uplink data, for example.

[0155] Example 5, the network device implicitly informs the OCC sequence matrix through the number of repetitions of the initial uplink data, and informs the OCC sequence index of the first terminal through the indication information. For example, the first terminal side pre-stores a mapping relationship between the number of repetitions and the OCC sequence index, and through the number of repetitions of the initial uplink data and the mapping relationship, the OCC sequence index of the first terminal can be determined, and then the OCC sequence of the first terminal is determined from the OCC sequence matrix based on the OCC sequence index of the first terminal.

[0156] Table 2 below shows a correspondence between an OCC sequence index and a corresponding OCC sequence. As shown in Table 2, after determining the OCC sequence index of the first terminal through the mapping relationship between the number of repetitions and the OCC sequence index, the OCC sequence w of the first terminal can be determined. nAs shown in Table 2, for example, OCC index 0 corresponds to an OCC sequence composed of w0, w1, w2, and w3.

[0157] Table 2

[0158] In a possible implementation, the network device can be preconfigured with a transmission configuration parameter, where the transmission configuration parameter includes at least one of the following 2.1 to 2.3:

[0159] 2.1, a repetition number of initial uplink data.

[0160] The repetition number of initial uplink data refers to the number of repetitions of initial uplink data transmission, and the repetition number is one or more.

[0161] 2.2, a number of time domain symbols for data transmission.

[0162] The number of time domain symbols for data transmission refers to the number of time domain symbols configured by the network device for transmitting data signals. Among the time domain symbols configured by the network device, there are time domain symbols for data transmission and time domain symbols for DMRS transmission. In the embodiment of the present disclosure, the time domain symbols for data transmission are time domain symbols other than the time domain symbols for DMRS transmission among the time domain symbols configured by the network device, and the number of time domain symbols for data transmission is the number of time domain symbols for data transmission.

[0163] Taking the length of the time domain symbols configured by the network device as L for example, the number of time domain symbols for data transmission is L1, and the number of time domain symbols for DMRS transmission is L2, then L1=L-L2. It should be noted that the L1 time domain symbols for data transmission can be L1 continuous time domain symbols or L1 non-continuous time domain symbols.

[0164] 2.3, a number of TBoMS slots.

[0165] The number of TBoMS slots refers to the number of slots for transmitting one TB. Taking the number of TBoMS slots as N for example, N slots are used for transmitting one TB. The network device can indicate the number of TBoMS slots N through a high-layer parameter numberOfSlotsTBoMS. In the case where the network device is not configured with the high-layer parameter numberOfSlotsTBoMS, one slot is used for transmitting one TB.

[0166] In the above embodiment, the implementation of the indication information indicating the OCC sequence of the first terminal is introduced, and the implementation scheme of processing the initial uplink data based on the OCC sequence of the first terminal and the transmission configuration parameter is introduced below with reference to the drawings.

[0167] In a possible implementation, the OCC sequence of the first terminal satisfies: a number of spreading factors included in the OCC sequence of the first terminal is equal to the number of repetitions of the initial uplink data. The first terminal performs time domain orthogonal spread on each repetition of the multiple repetitions of the uplink data by using the OCC sequence of the first terminal, thereby improving system uplink capacity.

[0168] In the case where the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of repetitions of the initial uplink data, the target uplink data includes multiple repetitions of respective uplink data, where the multiple repetitions of respective uplink data are products of respective spreading factors in the OCC sequence of the first terminal and the initial uplink data.

[0169] FIG. 4 is a schematic diagram of uplink data transmission according to an embodiment of the present disclosure, where the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of repetitions of the initial uplink data.

[0170] In the example of FIG. 4, the number of repetitions of the initial uplink data is K, the OCC sequence of the first terminal is [w0, w1,..., wK-1], w0, w1,..., wK-1 represent K spreading factors in the OCC sequence of the first terminal. K-1 ] and w0, w1,..., wK-1 represent K spreading factors in the OCC sequence of the first terminal. K-1 ] and w0, w1,..., wK-1 represent K spreading factors in the OCC sequence of the first terminal.

[0171] When the network device is not configured with the number of TBoMS slots, or the network device is configured with the number of TBoMS slots as 1, the first terminal transmits one TB, i.e., one initial uplink data, in one slot. For example, in FIG. 4, the slot m is used to transmit one initial uplink data, the slot m+1 is used to transmit one initial uplink data, and so on.

[0172] For any ith repetition transmission, the first terminal multiplies the ith spreading factor in the OCC sequence of the first terminal with the initial uplink data to obtain corresponding uplink data of the ith repetition transmission, and then sends the corresponding uplink data of the ith repetition transmission to the network device.

[0173] As shown in FIG. 4, the initial uplink data is represented as D, where for any ith repetition transmission, the corresponding initial uplink data is represented as Di, i.e., Di = D × wi, where wi represents the ith spreading factor in the OCC sequence of the first terminal. i The effective information of the initial uplink data corresponding to each repetition transmission is the same, but the redundancy version can be the same or different. That is, in the example of FIG. 4, the effective information included in D1, D2,..., DK-1 is the same, and the redundancy version of D1, D2,..., DK-1 can be the same or different. K The effective information of the initial uplink data corresponding to each repetition transmission is the same, but the redundancy version can be the same or different. That is, in the example of FIG. 4, the effective information included in D1, D2,..., DK-1 is the same, and the redundancy version of D1, D2,..., DK-1 can be the same or different. Kmay be the same or different. For the first repeated transmission, the first spreading factor w0 in the OCC sequence of the first terminal is multiplied by the initial uplink data D1, and the uplink data corresponding to the first repeated transmission w0*D1 is obtained; for the second repeated transmission, the second spreading factor w1 in the OCC sequence of the first terminal is multiplied by the initial uplink data D2, and the uplink data corresponding to the second repeated transmission w1*D2 is obtained;...; for the Kth repeated transmission, the Kth spreading factor wK in the OCC sequence of the first terminal is multiplied by the initial uplink data D, and the uplink data corresponding to the Kth repeated transmission wK*D is obtained. K-1 and the initial uplink data D K , and the initial uplink data D K-1 , and the initial uplink data D K .

[0174] Since the OCC sequences of each two terminals in the plurality of terminals are in an orthogonal relationship, the plurality of terminals can support uplink data transmission on the same resource, and the maximum number of terminals supported depends on the length of the OCC sequence. Based on the example of FIG. 4, in the case where time domain spreading is not used, K time slots support only one terminal to perform K repeated transmissions, and in the case where time domain spreading is used, K time slots support K terminals to perform K repeated transmissions respectively, thereby improving the uplink capacity of the system.

[0175] FIG. 5 is a schematic diagram of uplink transmission two provided by an embodiment of the present disclosure, and FIG. 5 shows the process of uplink data transmission in the case where the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of repetitions of the initial uplink data.

[0176] In the example of FIG. 5, the number of repetitions of the initial uplink data is K, the OCC sequence of the first terminal is [w0, w1,..., wK], w0, w1,..., wK represent the K spreading factors in the OCC sequence of the first terminal. K-1 K-1 In the example of FIG. 5, the number of repetitions of the initial uplink data is K, the OCC sequence of the first terminal is [w0, w1,..., wK], w0, w1,..., wK represent the K spreading factors in the OCC sequence of the first terminal.

[0177] The number of TBoMS time slots configured by the network device is N, and the first terminal transmits one TB through N time slots, that is, one initial uplink data. For example, in FIG. 5, time slots m+1 to m+N are used to transmit one initial uplink data, time slots m+N+1 to m+2N are used to transmit one initial uplink data, and so on. The value of N may, for example, be 2, 4, 8, and the like.

[0178] For any ith repeated transmission, the first terminal multiplies the ith spreading factor in the OCC sequence of the first terminal by the initial uplink data, and the result obtained is the uplink data corresponding to the ith repeated transmission, and then the first terminal sends the uplink data corresponding to the ith repeated transmission to the network device.

[0179] ​As shown in FIG. 5, the initial uplink data is denoted as D, wherein, for any ith repeated transmission, the corresponding initial uplink data is denoted as D i , the valid information of the initial uplink data corresponding to each repeated transmission is the same, but the redundancy versions can be the same or different. That is, in the example of FIG. 4, the valid information included in D1, D2,..., D K is the same, and D1, D2,..., D K may be the same or different.

[0180] Since the number of TBoMS slots is N, the time domain resource allocated for one transmission of each initial uplink data is in multiple slots, and therefore, when orthogonal time domain spreading is performed, the K spreading factors are multiplied by the data corresponding to each repeated transmission located in the multiple slots, respectively. Therefore, for the 1st repeated transmission, the 1st spreading factor w0 in the OCC sequence of the first terminal is multiplied by the initial uplink data of each slot in the slot m+1 to the slot m+N, and the uplink data corresponding to the 1st repeated transmission w0*D1 is obtained; for the 2nd repeated transmission, the 2nd spreading factor w1 in the OCC sequence of the first terminal is multiplied by the initial uplink data of each slot in the slot m+N+1 to the slot m+2N, and the uplink data corresponding to the 2nd repeated transmission w1*D2 is obtained;...; for the Kth repeated transmission, the Kth spreading factor w K-1 in the OCC sequence of the first terminal is multiplied by the initial uplink data of each slot in the slot m+(K-1)N+1 to the slot m+KN, and the uplink data corresponding to the Kth repeated transmission w K-1 *D K is obtained.

[0181] Since the OCC sequences of each two terminals in the multiple terminals are in an orthogonal relationship, the multiple terminals can support uplink data transmission on the same resource, and the maximum number of terminals supported depends on the length of the OCC sequence. Based on the example of FIG. 5, it can be known that, in the manner without time domain spreading, K slots support one terminal to perform K repeated transmissions, and in the manner with time domain spreading, K slots support K terminals to respectively perform K repeated transmissions, and the system uplink capacity is improved.

[0182] In a possible implementation manner, the OCC sequence of the first terminal satisfies that: the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of time domain symbols mapped by the initial uplink data, wherein the number of time domain symbols mapped by the initial uplink data is equal to the number of time domain symbols used for data transmission, or the number of time domain symbols mapped by the initial uplink data is equal to the product of the number of time domain symbols used for data transmission and the number of TBoMS slots.

[0183] In a case where the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of time domain symbols to which the initial uplink data is mapped, the target uplink data includes target time domain data corresponding to each of the plurality of time domain symbols, and wherein:

[0184] For each time domain symbol, the target time domain data corresponding to the time domain symbol is equal to a product of initial time domain data mapped to the time domain symbol by the spreading factor corresponding to the time domain symbol in the OCC sequence of the first terminal. The initial time domain data on each time domain symbol is signal data after Orthogonal Frequency Division Multiplexing (OFDM) modulation, i.e., signal data after Inverse FAST Fourier Transform (IFFT) and addition of a Cyclic Prefix (CP).

[0185] The first terminal multiplies each symbol of the OFDM-modulated time domain signal by each spreading factor of the OCC sequence of the first terminal to obtain new data on each time domain and send the new data to the network device according to the OCC sequence of the first terminal. If the network device configures the initial uplink data to be repeated more than once, the same OCC sequence is used for multiple repetitions.

[0186] FIG. 6 is a schematic diagram of uplink transmission according to an embodiment of the present disclosure, which illustrates a case where the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of time domain symbols to which the initial uplink data is mapped.

[0187] In the example of FIG. 6, the network device configures a time domain symbol length of L, including a number of time domain symbols L2 (not shown in the figure) for DMRS transmission and a number of time domain symbols L1 for data transmission, and the initial uplink data is repeated K times. The number of time domain symbols to which the initial uplink data is mapped is N*L1. The OCC sequence of the first terminal is The N*L1 spreading factors in the OCC sequence of the first terminal are represented by

[0188] The network device configures a number of TBoMS slots N, and the first terminal transmits one TB, i.e., one initial uplink data, through N slots. In a case where the number of spreading factors included in the OCC sequence of the first terminal is equal to the number of time domain symbols to which the initial uplink data is mapped, the initial uplink data can be transmitted only once or K times repeatedly, wherein the OCC sequence used for each repetition is the same, and the processing manner is also the same. The following describes the process of the first uplink transmission as an example.

[0189] As shown in FIG. 6, for the first uplink transmission, the initial uplink data is transmitted through N time slots, and the number of time domain symbols used for data transmission is L1, so the number of time domain symbols mapped by the initial uplink data is N*L1.

[0190] For any jth time domain symbol in the N*L1 time domain symbols, the first terminal multiplies the jth spreading factor in the OCC sequence of the first terminal with the initial time domain data mapped by the initial uplink data on the jth time domain symbol, and the result is the target time domain data corresponding to the jth time domain symbol. The target uplink data includes the target time domain data corresponding to each of the N*L1 time domain symbols, and the first terminal sends the target time domain data corresponding to each of the N*L1 time domain symbols to the network device.

[0191] As shown in FIG. 6, The initial uplink data mapped on the first time domain symbol, the initial uplink data mapped on the second time domain symbol,..., and the initial uplink data mapped on the L1th time domain symbol are sequentially represented. Then, multiplying the first spreading factor w0 in the OCC sequence of the first terminal with s0 can obtain the target time domain data s'0 corresponding to the first time domain symbol; multiplying the second spreading factor w1 in the OCC sequence of the first terminal with s1 can obtain the target time domain data s'1 corresponding to the second time domain symbol;...; multiplying the L1th spreading factor and in the OCC sequence of the first terminal with sL1 can obtain the target time domain data s'L1 corresponding to the L1th time domain symbol. The processing procedure of the initial time domain data mapped by the initial uplink data on other time domain symbols is similar, which is not described herein.

[0192] Since the OCC sequences of each two terminals in the multiple terminals are in an orthogonal relationship, multiple terminals can support uplink data transmission on the same resource, and the maximum number of terminals depends on the length of the OCC sequence. Based on the example of FIG. 6, K*N*L1 time domain symbols support uplink data transmission of only one terminal without using the spreading method, while K*N*L1 time domain symbols support uplink data transmission of N*L1 terminals respectively using the spreading method, which realizes the improvement of the system uplink capacity.

[0193] In summary, since the OCC sequences of each two terminals in the multiple terminals configured by the network device are in an orthogonal relationship, the target uplink data obtained by processing the initial uplink data through the OCC sequences of each terminal and the transmission configuration parameters can avoid cross interference, and can realize uplink data transmission of multiple terminals on the same time-frequency resource, thereby improving the capacity of the system uplink.

[0194] In an embodiment, the embodiment shown in FIG. 6 is for spreading of symbols, which can be used for repeated transmission, or can be applied in a scenario without repeated transmission.
