[0095] For ease of understanding, some content related to the embodiments of this application is explained as follows:

[0096] 1. NTN

[0097] The Non-Terrestrial Network (NTN) can enhance the uplink capacity, for example, enhance the DFT-s-OFDM PUSCH through Orthogonal Cover Code (OCC) to improve the capacity or throughput. In addition, some factors under actual deployment conditions (such as Doppler, time variation, phase distortion, etc.) need to be considered to achieve the goal of capacity improvement.

[0098] 2、Block-wise spreading

[0099] To improve the multiplexing ability of user equipment (UE, i.e., the terminal) and thus enhance the system capacity, a transmission method based on OCC (orthogonal cover code) block-wise spreading is introduced in PUCCH transmission.

[0100] The block-wise spreading scheme is as follows:

[0101] For PUCCH format 3 with interlaced mapping and PUCCH format 4, block-wise spreading shall be applied according to

[0102]

[0103] where

[0104] For PUCCH format 3 with interlaced mapping, if a single interlace is configured, then and if two interlaces are configured, then w n = 1 (for PUCCH format 3 with interlaced mapping, if a single interlace is configured and w n = 1 if two interlaces are configured);

[0105] For PUCCH format 4, is given by clause 9.2.1 of [5, TS 38.213], is given by the higher-layer parameter occ Length (for PUCCH format 4, is given by clause 9.2.1 of [5, TS 38.213] and is given by the higher-layer parameter occ-Length);

[0106] and w n is given by Tables 6.3.2.6.3-1 and 6.3.2.6.3-2 for where N is the index of the orthogonal sequence used according to clause 9.2.1 of [5, TS 38.213]. The quantity is given by the higher-layer parameter occ-Length if provided, otherwise (and w n is given by Tables 6.3.2.6.3-1 and 6.3.2.6.3-2 for where n is the index of the orthogonal sequence to use according to clause 9.2.1 of [5, TS 38.213]. The quantity is given by the higher-layer parameter occ-Length if provided, otherwise )

[0107] When the orthogonal sequences w n (m) (Orthogonal sequences w n (m) for PUCCH format 3 with interlaced mapping and PUCCH format 4 when ) are as shown in the following table:

[0108] n <![CDATA[w n > 0 [+1 +1] 1 [+1 -1]

[0109] When the orthogonal sequences w n (m) (Orthogonal sequences w n (m) for PUCCH format 3 with interlaced mapping and PUCCH format 4 when ) are as shown in the following table:

[0110] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 -j -1 +j] 2 [+1 -1 +1 -1] 3 [+1 +j -1 -j]

[0111] For PUCCH format 3, transmission with block-wise spreading is only supported in the case of interlace mapping, and multiplexing of 1 / 2 / 4 users is supported only when single interlace is configured;

[0112] For PUCCH format 4, multiplexing of 2 / 4 users is supported, which is configured by the higher layer parameter occ-Length.

[0113] As can be seen from the above formula,

[0114] (1) The addition of block-wise spreading is reflected in the frequency domain, and the OCC sequence (w_n) multiplied for each symbol in the time domain is the same;

[0115] (2) As can be seen from it is known that in the frequency domain, the continuous subcarriers that satisfy are multiplied by the same

[0116] (3) The above blocks are divided by 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 users.

[0117] (4) The maximum number of multiplexed users is 4.

[0118] (5) Only users allocated the same RB can be multiplexed together.

[0119] In addition, for the principle of block-wise spreading, it can be learned through the following process:

[0120] For 2-way UE multiplexing, UE 0 and UE 1 are (To 2UE multiplexing, for UE 0 and UE 1 are):

[0121] S0 = a0, a1, …, a 59 , a0, a1, …, a 59 ;

[0122] And (and)

[0123] S1 = b0, b1, …, b 59 , -b0, -b1, …, -b 59 .

[0124] Based on the FFT property, it is straightforward to see that DFT(S0) is non-zero on even tones only, while DFT(S1) is non-zero on odd tones only. The detailed derivation is given below:

[0125] Given a discrete-time signal x n , where n = 0, …, N - 1, the FFT of x n is given by n where n = 0, …, N - 1, the FFT of x n is given by:

[0126]

[0127] Now, if x n = x n+N / 2 , as in the signal from UE 0 n = x n+N / 2 , as in the signal from UE 0

[0128]

[0129] Obviously, when k is odd k X = 0.

[0130] Similarly, if x n = -x n+N / 2 , as in the signal from UE 1 n = -x n+N / 2 , as in the signal from UE 1

[0131]

[0132] Therefore, in this case, when k is even k X = 0.

[0133] Based on the above analysis, we can conclude that the pre-DFT-OCC user multiplexing is equivalent to the comb-based user multiplexing.

[0134] To multiplex 4 UEs, the Fourier basis can be used for the OCC spreading code: [1, 1, 1, 1], [1, j, -1, -j], [1, -1, 1, -1], [1, -j, -1, j]. Then, following the same proof as above, it can be shown that UEs are FDM-ed on every 4th REs and therefore the orthogonality between UEs still holds regardless of the delay spread of the channel. Thus, for OCC, pre-DFT OCC as in NR PUCCH Format 4 can be used.

[0135] As can be seen from the above principle introduction, for block-wise spreading, after different UEs are multiplied by different OCC sequences and then utilizing the characteristics of the FFT transform, different UEs occupy different REs when mapped in the frequency domain after pre-DFT transformation. For example, UE0 occupies odd REs and UE1 occupies even REs, thus achieving the effect of comb mapping and realizing multi-user multiplexing.

[0136] An example of the block-wise spreading scheme is as follows:

[0137] Assume 4 users are multiplexed, and the bandwidth allocated to each user is 2 RBs. Then the changes before and after pre-DFT are as Figure 2a , Figure 2b , Figure 2c and Figure 2d shown.

[0138] 3. Determination of TBS

[0139] The TBS of PUSCH is calculated based on the following parameters:

[0140] Available resources: the number of allocated time-domain symbols, the number of allocated frequency-domain PRBs;

[0141] The modulation order Q corresponding to the MCS level m , the target code rate R;

[0142] The number of layers υ.

[0143] The calculation process of TBS is as follows:

[0144] Step 1: Calculate the number of available REs

[0145] (1) Calculate the number of available REs in one PRB: where indicates that one PRB contains 12 subcarriers in the frequency domain; is the number of symbols of the scheduled PUSCH in one time slot; is the overhead of DMRS in one PRB; is configured by the xOverhead field in the high-layer parameter PUSCH-ServingCellConfig, considering the overhead of CSI-RS, CORESET, etc. The default value is 0, and the configurable values are {6, 12, 18}. For Msg3 PUSCH transmission, it is set to 0.

[0146] (2) Calculate the total number of available REs for the configured PUSCH transmission: N RE = min(156, N' RE ) · n PRB , where n PRB is the number of PRBs allocated to the UE

[0147] Step 2: Calculate the number of intermediate information bits: N info = N RE · R · Q m · υ

[0148] When N info ≤ 3824, Step 3 is adopted;

[0149] Otherwise, adopt Step 4.

[0150] Step 3: When N info ≤ 3824,

[0151] (1) Quantize the number of intermediate information bits where

[0152] (2) Find the nearest TBS not less than N Figure 3 in i ' nfo . Figure 3 The TBS under N info ≤ 3824 is given.

[0153] Step 4: When N info > 3824,

[0154] Quantize the intermediate number where,

[0155] If the target code rate R ≤ 1 / 4,

[0156] where

[0157] Otherwise (R > 1 / 4),

[0158] If N' info > 8424, where

[0159] Otherwise,

[0160] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the communication operation execution method, information reception method, device and related equipment provided by the embodiments of the present application will be described in detail.

[0161] See Figure 4 , Figure 4 is a flowchart of a communication operation execution method provided by an embodiment of the present application. As Figure 4 shown, the communication operation execution method includes the following steps:

[0162] Step 101, the terminal executes the first operation;

[0163] The first operation includes at least one of the following:

[0164] The terminal determines the transmission mode of the first uplink transmission based on the first information;

[0165] The terminal determines the transmission mode of the first uplink transmission based on the information included in the first uplink transmission;

[0166] The terminal determines the transmission mode of the first uplink transmission based on the target condition;

[0167] The terminal performs the transmission of the first uplink transmission using the first transmission mode;

[0168] Wherein, the first transmission mode is to perform uplink transmission based on an Orthogonal Cover Code (OCC) sequence, the first transmission mode is one of the transmission modes of the first uplink transmission, and the first information is used to determine the OCC sequence.

[0169] Wherein, the first uplink transmission may include control information, or, the first uplink transmission may include control information and data. The control information may be Uplink Control Information (UCI), or other control information. For example, the control information may include at least one of HARQ-ACK, CSI, and SR. This embodiment does not limit this.

[0170] Wherein, the first information may include at least one of the following:

[0171] The relevant information of the target block; OCC configuration information.

[0172] In one implementation, the relevant information of the target block may include at least one of the following:

[0173] The size of the target block; the number of target blocks; the bitmap information of the target block; the position information of the target block; the number of the target block; the enable information of the target block;

[0174] Wherein, the bitmap information of the target block is used to determine whether to enable the application of the OCC sequence within the target block.

[0175] Wherein, the enable information of the target block may indicate whether to enable the target block.

[0176] It should be noted that the target block in the at least one target block is only a code name, representing a code name for some resource sets in the frequency domain for the uplink transmission. For example, it can also be described as a block, or a multiplexing block, or a resource set, or a multiplexing resource block, etc.

[0177] Wherein, the size of the target block can be used to determine the resource size occupied by a target block in the frequency domain. In one target block, data of at least one user (i.e., terminal) can be multiplexed, and each target block performs an independent DFT transform (such as transmission precoding or pre-DFT transform).

[0178] In addition, the size of the target block can be in units of resource elements (REs), sub-carriers, RBs, or resource element groups (REGs). For example, for the Internet of Things (IoT), scheduling can be performed on a single tone or multi-tones basis. Therefore, the size of the target block can be less than 1 RB. In NR, the scheduled frequency domain resources are based on RBs as the basic granularity. Therefore, the size of the target block can be greater than or equal to 1 RB.

[0179] In addition, the size of the target block can be indicated separately, coordinated with the frequency domain resource allocation (FDRA), specified by the protocol, or implicitly determined through other indication information, such as determined by the number of users or user groups multiplexed on the target block by the frequency domain resources and the OCC length.

[0180] In one implementation, the following relationship holds among the size of the target block, the number of target blocks, and the allocated resources: Size of target block * Number of target blocks = Frequency domain resources allocated for uplink transmission (number of RBs, REs, or sub-carriers) or transmission bandwidth (the number can be represented by the number of REs or sub-carrier count, and the same granularity is maintained among several variables).

[0181] In addition, based on the size of the target block and in combination with the frequency domain resources allocated by the FDRA, the number of target blocks can also be determined.

[0182] It should be noted that the number of target blocks indicates how many target blocks the frequency domain resources allocated by the FDRA are divided into. Indirectly, it also determines the size of the target block.

[0183] In one implementation, the bitmap of the target block corresponds to the number of target blocks and indicates whether each target block enables target uplink transmission. If not enabled, it means that target uplink transmission is not performed, and uplink transmission proceeds according to the normal process, or whether target uplink transmission is enabled is achieved through the dedicated enable information of the target block. The target uplink transmission is uplink transmission based on the OCC sequence within the at least one target block.

[0184] The position of the target block is determined based on the frequency domain resources allocated by the FDRA, as well as the size or number of target blocks.

[0185] In one implementation, the OCC configuration information can be used to configure at least one of the following:

[0186] OCC-based sequence information; OCC index information; OCC length; OCC multiplexing factor.

[0187] Among them, the OCC multiplexing factor can characterize the number of multiplexed users. For example, how many users can be multiplexed within the target block.

[0188] Among them, the OCC-based sequence information may include information such as an OCC-based sequence set, an OCC-based sequence table, or an OCC-based sequence for determining the OCC-based sequence.

[0189] Among them, the OCC index information may include information such as an OCC index, an OCC index set, or an OCC index table for determining the OCC index.

[0190] In one implementation, the OCC configuration information may include at least one of the following: an OCC-based sequence set or an OCC-based sequence, an OCC index or an OCC index set, an OCC length, an OCC multiplexing factor.

[0191] Among them, the OCC index is used to determine which OCC-based sequence to select from the OCC-based sequence set, and the corresponding OCC-based sequence can be obtained from the OCC-based sequence set through the OCC index and the OCC length.

[0192] The above OCC index set is used to indicate the OCC index used by different streams. For example, the first OCC index in the OCC index set corresponds to the OCC index used on the first stream.

[0193] Among them, different target blocks may indicate different OCC indexes.

[0194] Among them, the OCC length is the length of an OCC-based sequence and can be determined by the maximum number of multiplexed users supported in the target block.

[0195] In one implementation, the OCC sequence can be obtained through a first operation based on the OCC-based sequence and the size of the target block.

[0196] In one implementation, the OCC sequence can be obtained through a first operation corresponding to the size of the target block by the OCC-based sequence.

[0197] Among them, the OCC-based sequence can be the OCC-based sequence carried by the first information or the OCC sequence in the related art, such as OCC2 or OCC4.

[0198] OCC2 is shown in the following table:

[0199] n <![CDATA[w n > 0 [+1 +1] 1 [+1 -1]

[0200] OCC4 is shown in the following table:

[0201] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 -j -1 +j] 2 [+1 -1 +1 -1] 3 [+1 +j -1 -j]

[0202] Among them, the first operation may be to repeat each element in the OCC base sequence the same number of times to obtain a sequence with the same length as the target block.

[0203] It should be noted that the size of the target block can be divided by the length of the OCC base sequence to obtain the number of times each element in the OCC sequence needs to be repeated. For example, if the size of the target block is 2RB = 24REs and the OCC base sequence is: [1 1i -1 -1i], then the OCC sequence used within the target block after applying the first operation is: [1 1 1 1 1 1 1i 1i 1i 1i 1i 1i -1 -1 -1 -1 -1 -1 -1i -1i -1i -1i -1i -1i].

[0204] In one implementation, the transmission mode of the first uplink transmission determined by the terminal based on the first information may be the first transmission mode. The terminal determines the OCC sequence based on the first information and performs the transmission of the first uplink transmission based on the OCC sequence.

[0205] Among them, when the terminal performs the transmission of the first uplink transmission using the first transmission mode, it may include: the terminal performs uplink transmission based on the OCC sequence within at least one target block, and the OCC sequences corresponding to the at least one target block are the same; or when the first uplink transmission is PUSCH, the terminal performs uplink transmission through block-wise spreading based on OCC. The implementation of block-wise spreading based on OCC for PUSCH is similar to the implementation of block-wise spreading based on OCC for PUCCH in the related art and will not be elaborated here.

[0206] It should be noted that the target block may also be described as a block, or a multiplexing block, etc. The fact that the OCC sequences corresponding to the at least one target block are the same can be understood as that for the same transmission of the same terminal within different target blocks, the OCC sequences used are the same.

[0207] It should be noted that the first uplink transmission can be understood as uplink resources.

[0208] Among them, the first uplink transmission may include Physical Uplink Control Channel (PUCCH) transmission, Physical Uplink Shared Channel (PUSCH) transmission, Narrowband Physical Uplink Shared Channel (NPUSCH) transmission, etc., and this embodiment does not limit this.

[0209] In one implementation, the first uplink transmission may be PUSCH.

[0210] In one implementation, when the UE determines that at least part of the first uplink transmission is not transmitted in the transmission mode determined based on the first information or is transmitted using other methods, when generating or processing the bit stream corresponding to at least part of the first uplink transmission, the corresponding OCC is a sequence of all 1s, or the operations related to the OCC are skipped. The other method may be a transmission method that directly maps the information to be transmitted to the transmission resources for transmission.

[0211] In one implementation, when the UE determines that at least part of the first uplink transmission is determined based on the first information for the transmission mode of the first uplink transmission, when generating or processing the bit stream corresponding to at least part of the first uplink transmission, the corresponding OCC is a sequence determined based on the first information.

[0212] In one implementation, the terminal uses the first transmission method to perform the first uplink transmission, which may include that the terminal performs uplink transmission based on the OCC sequence within at least one target block. The terminal performing uplink transmission based on the OCC sequence within at least one target block includes:

[0213] The terminal multiplies the transmission symbols mapped in each target block in the at least one target block by the OCC sequence to obtain the first transmission symbol corresponding to each target block;

[0214] The terminal performs discrete Fourier transform (DFT) processing on the first transmission symbol corresponding to each target block to obtain the second transmission symbol corresponding to each target block;

[0215] The terminal performs uplink transmission based on the second transmission symbol corresponding to each target block.

[0216] Among them, the DFT processing may include DFT processing corresponding to transmission precoding. For example, Pre-DFT transform. The Pre-DFT transform may also be described as transmission precoding transform.

[0217] Among them, the transmission symbol can refer to the complex-valued constellation point symbol after modulation. All physical layer processes from after modulation to before resource mapping are processed in the form of transmission symbols (or described as symbol-level processing or non-bit-level processing).

[0218] In one implementation, the uplink transmission based on the OCC sequence within the target block can be that after multiplying the transmission symbols mapped within the target block by the OCC sequence, a pre-DFT transform or transmission precoding is performed to obtain the transmission symbols before frequency domain mapping.

[0219] For example, give a formula similar to format 4.

[0220] Assume that d(0), …, d(M symb -1) are the replicated modulation symbols before the uplink transmission operation based on the OCC sequence within the target block, and y(0), …, y(M symb L-1) represent the replicated modulation symbols before the pre-DFT transform or transmission precoding.

[0221] In one implementation, for symbol #l within target block #i, the transmission symbols mapped within the target block are multiplied by the OCC sequence, corresponding to the following formula:

[0222]

[0223] Where:

[0224] i = 0, 1, …, M block -1;

[0225]

[0226]

[0227]

[0228] l = 0, 1, …, (M symb L / M sc )-1;

[0229] M sc represents the number of subcarriers or REs corresponding to the frequency domain resources allocated for uplink transmission;

[0230] M symb represents the number of replicated modulation symbols that can be transmitted by the uplink transmission;

[0231] M block represents the number of target blocks (within the uplink transmission allocated bandwidth / frequency domain resources);

[0232] Represents the size of the target block, in units of RE or the number of sub - carriers;

[0233] L represents the OCC length or the multiplexing factor;

[0234] Represents the number of complex - valued modulation symbols transmitted within a target block;

[0235] n is determined by the OCC index, w n Represents the OCC base sequence;

[0236] Satisfies:

[0237] In one implementation, for the entire uplink transmission (including all time - domain symbols scheduled, i.e., l = 0, 1, …, (M symb L / M sc ) - 1):

[0238]

[0239] Where:

[0240] k = 0, 1, …, M sc - 1; l = 0, 1, …, (M symb L / M sc ) - 1;

[0241] M sc Represents the number of sub - carriers or REs corresponding to the frequency - domain resources allocated for the uplink transmission;

[0242] M symb Represents the number of replicated modulation symbols that can be transmitted in the uplink transmission;

[0243] M block Represents the number of target blocks (within the bandwidth or frequency - domain resources allocated for the uplink transmission);

[0244] Represents the size of the target block, in units of RE or the number of sub - carriers;

[0245] L represents the OCC length or the multiplexing factor;

[0246] Represents the number of complex - valued modulation symbols transmitted within a target block;

[0247] n is determined by the OCC index, w n Represents the OCC base sequence;

[0248] Satisfies:

[0249] It can be seen from the above formula that the number of complex - valued symbols needs to be scaled compared to the normal uplink transmission process.

[0250] In one implementation, the transmission of the first uplink transmission by the terminal using the first transmission method may include: the terminal maps transmission symbols to the first transmission units in at least one target block; the terminal performs uplink transmission based on the first OCC sequence within the at least one target block; wherein, the transmission symbols are mapped to the first transmission units through the second OCC sequence, or the first OCC sequences corresponding to the at least one target block are the same. The first information may further include information related to the first transmission units, and the information related to the first transmission units includes at least one of the following: the size of the first transmission units; the number of the first transmission units; the position of the first transmission units; the numbering of the first transmission units. Wherein, one target block may include one or more first transmission units, and the size, number, position, or numbering of the first transmission units is defined within one target block; or in one target block, one or more first transmission units are divided.

[0251] It should be noted that the first transmission unit is only a code name, representing a code name for some resource sets divided from the target block. For example, it can also be described as a sub-block, or a multiplexed sub-block, or a resource subset, or a multiplexed resource sub-block, etc.

[0252] In one implementation, the terminal mapping the transmission symbols to the first transmission units in at least one target block may include any one of the following:

[0253] The terminal multiplies the transmission symbols mapped by the first transmission units in at least one target block with the corresponding second OCC sequence to obtain third transmission symbols, and performs transformation processing on the first transmission symbols to obtain the corresponding fourth transmission symbols on the first transmission units;

[0254] The terminal maps the transmission symbols mapped by the first transmission units in at least one target block to the first transmission units through the first mapping method;

[0255] Wherein, the first mapping method includes at least one of the following:

[0256] Sub - physical resource block (sub - PRB) mapping; single tone mapping; multi - tones mapping; comb mapping; interlace mapping.

[0257] In one implementation, the realization of the terminal multiplying the transmission symbols mapped by the first transmission units in at least one target block with the corresponding second OCC sequence to obtain third transmission symbols, and performing transformation processing on the first transmission symbols to obtain the corresponding fourth transmission symbols y on the first transmission units is as follows:

[0258] Assume is the replicated modulation symbol before the uplink transmission operation based on the second OCC sequence in the first transmission unit, and y(0), …, y(L-1) represent the replicated modulation symbols before the pre-DFT transform;

[0259] For the symbol #l in the first transmission unit #i, the transmission symbol mapped in the first transmission unit is multiplied by the second OCC sequence, corresponding to the following formula:

[0260]

[0261] Where:

[0262] i = 0, 1, …, M block -1;

[0263]

[0264]

[0265] M block represents the number of the first transmission units in a target block;

[0266] represents the size of the target block, in units of RE or subcarrier number;

[0267] L represents the OCC length or multiplexing factor;

[0268] represents the number of complex-valued modulation symbols transmitted in a first transmission unit for the current UE;

[0269] n is determined by the OCC index, and w n represents the second OCC base sequence;

[0270] The first transmission unit #i is the number or index of the first transmission unit corresponding to the current terminal.

[0271] In addition, after multiplying by the corresponding second OCC sequence in the first transmission unit, the implementation of mapping to the corresponding transmission resources after the pre-DFT transform is as follows:

[0272] After the pre-DFT transform, y(0), …, y(L-1) become Y(0), …, Y(L-1), and Y(0), …, Y(L-1) are mapped to the transmission resources corresponding to the first transmission unit, thereby obtaining the complex-valued transmission symbols before the uplink transmission operation based on the first OCC sequence in the target block.

[0273] It should be noted that the implementation of the terminal for uplink transmission based on the first OCC sequence within the at least one target block is similar to the aforementioned implementation of the terminal for uplink transmission based on the OCC sequence within the at least one target block, and will not be elaborated here.

[0274] In one implementation, the UE determines whether to determine the transmission mode of the first uplink transmission based on the first information.

[0275] In the NTN scenario, due to the large coverage area, the number of simultaneously connected users may be relatively large. To improve the system capacity and enhance the ability of uplink user multiplexing, it is necessary to enhance the capacity of the uplink channel. Since only single-layer transmission is supported in the NTN scenario and the DMRS ports already support multi-port multiplexing, it is necessary to enhance the capacity of the data part of the uplink channel. In the embodiments of the present application, the terminal performs the first uplink transmission using the first transmission mode, and performs uplink transmission through the OCC sequence to achieve multi-user multiplexing of OCC, which can solve the above limitations.

[0276] It should be noted that the embodiments of the present application are applicable to the NTN scenario, but not limited to the NTN scenario. For example, the TN scenario is also applicable.

[0277] The embodiments of the present application are applicable not only to the NR system, but also to the LTE NB-IoT or IoT NTN system, etc.

Through the OCC sequence, multiplexing of transmission resources can be achieved, the utilization rate of transmission resources can be improved, and thus the uplink transmission effect can be improved.

[0279] Optionally, the target condition includes a first condition. The terminal determines the transmission mode of the first uplink transmission based on the target condition, including:

[0296] The terminal is instructed with, configured with, or activated with first information for determining the OCC sequence.

[0297] The terminal is instructed with, configured with, or activated with the first transmission mode.

[0299] It should be noted that the settings of the preset value or preset range in the embodiments of the present application may be related to the first information. By way of example, the preset value or preset range in the embodiments of the present application may be constrained by the OCC length or the OCC sequence length determined based on the first information, for example, being a multiple or a factor of the OCC length or the OCC sequence length.

[0369] In addition, taking the second indication information used to indicate whether the first uplink transmission containing control information uses or does not use the first information as an example, the second indication information can be indication information of 2 bits. For example, the first bit is used to represent using the first information, and the second bit is used to represent not using the first information; or the second indication information can be indication information of 1 bit, and this 1-bit indication information can be 0 or 1. For example, when the second indication information is 0, it represents using the first information, and when the second indication information is 1, it represents not using the first information; and so on. The specific implementation of the second indication information in this embodiment is not limited.

[0370] In one implementation manner, the base station indicates to the terminal which part of the resources or which part of the bits (bit) needs to determine the transmission method based on the first information, or, the base station indicates to the terminal which part of the resources or which part of the bits does not determine the transmission method based on the first information (for example, using the current transmission method), or indicates at least one of the first condition or the second condition. The base station can indicate at least a part of the first uplink transmission, and the part indicated by the base station may need to determine the transmission method based on the first information, or does not need to determine the transmission method based on the first information.

[0371] For example, the first uplink transmission includes UCI and data, and the transmission of the UCI part does not use the transmission method corresponding to OCC, while the transmission of the data part uses the transmission method corresponding to OCC. Then, the base station can indicate which parts of the bit string corresponding to the first uplink transmission use the transmission method corresponding to OCC, or which parts do not need to use the transmission method corresponding to OCC.

[0372] For example, the base station indicates a set that includes at least one of {UCI, data}. If the set includes UCI and data, it means that the transmissions of both UCI and data need to use the transmission method corresponding to OCC. If it only includes data, it means that only the transmission of data needs to use the transmission method corresponding to OCC.

[0373] For example, if UCI or data has corresponding enabling information, and the base station provides this enabling information or sets it to enable, it indicates that the transmission of UCI or data uses the transmission method corresponding to OCC. The UCI and data parts can use a unified enabling information, or each can have its own corresponding enabling information.

[0374] For example, if UCI or data has corresponding disabling information, and the base station provides this disabling information or sets it to disable, it indicates that the transmission of UCI or data does not use the transmission method corresponding to OCC or is transmitted based on other methods. The UCI and data parts can use a unified disabling information, or each can have its own corresponding disabling information.

[0375] It should be noted that when the base station indicates to the terminal which part of the bits uses the transmission method corresponding to OCC or which part of the bits does not use the transmission method corresponding to OCC, it can indicate the start point, length, end point, corresponding position, or number of this part; when the base station indicates to the terminal which part of the resources uses the transmission method corresponding to OCC or which part of the resources does not use the transmission method corresponding to OCC, it can indicate the start point, length, end point, corresponding position, or number of this resource.

[0376] In this embodiment, the terminal receives the second indication information sent by the network-side device, and thus can determine the transmission mode of the first uplink transmission based on the first information indicated by the second indication information, or determine the transmission mode of the first uplink transmission based on the second indication information and the information included in the first uplink transmission, which can improve the flexibility of determining the transmission mode and thus improve the uplink transmission effect.

[0377] Optionally, at least part of the first information corresponding to the control information of the first uplink transmission is different from the first information corresponding to the data of the first uplink transmission.

[0378] Optionally, when the first uplink transmission includes control information, the terminal determines the transmission mode of the first uplink transmission based on the information included in the first uplink transmission, including at least one of the following:

[0379] The terminal determines that the transmission mode of the control information is a second transmission mode, and the second transmission mode is different from the first transmission mode;

[0380] The terminal determines that the transmission mode of the control information is the first transmission mode, and the OCC sequence corresponding to the first transmission mode is a preset sequence;

[0381] The terminal determines that the transmission mode of the first uplink transmission is a second transmission mode, and the second transmission mode is different from the first transmission mode;

[0382] The terminal determines that the transmission mode of the first uplink transmission is the first transmission mode, and the OCC sequence corresponding to the first transmission mode is a preset sequence;

[0383] The terminal determines that the first uplink transmission or the transmission of the control information does not use the first information;

[0384] The terminal determines that the first uplink transmission or the transmission of the control information ignores the first information;

[0385] The terminal determines that the first uplink transmission or the transmission of the control information is deactivated from the first transmission mode;

[0386] The terminal does not perform the first uplink transmission.

[0387] In the related art, for a block-wise spreading transmission mode similar to PUCCH format 4, multi-user multiplexing can be achieved using an OCC sequence. When using an OCC sequence for multi-user multiplexing of uplink transmissions (such as PUSCH), the implementation methods may be different. Taking the first uplink transmission as PUSCH as an example, when the first uplink transmission includes control information (such as UCI), the terminal can determine the transmission mode of the first uplink transmission based on the information included in the first uplink transmission.

[0388] Optionally, the terminal does not expect the first uplink transmission to overlap with a second uplink transmission, and the second uplink transmission is an uplink transmission other than the first uplink transmission.

[0389] Optionally, when the first uplink transmission overlaps with the second uplink transmission, before the terminal determines the transmission mode of the first uplink transmission based on the first information, the method includes at least one of the following:

[0390] Based on the first uplink transmission and the second uplink transmission, the terminal determines whether to transmit the first uplink transmission;

[0391] Based on the first uplink transmission and the second uplink transmission, the terminal determines the control information carried on the first uplink transmission;

[0392] Wherein, the second uplink transmission is an uplink transmission other than the first uplink transmission.

[0393] Wherein, in the case where the first uplink transmission and the second uplink transmission overlap, it is possible to determine whether to transmit the first uplink transmission, or the UCI carried on the first uplink transmission, based on the first uplink transmission and the second uplink transmission; then determine the transmission mode of the first uplink transmission.

[0394] Exemplarily, the first uplink transmission includes UCI and data. The UCI part is transmitted using an OCC sequence or according to the transmission mode determined by the first information, or the data part is transmitted using an OCC sequence or according to the transmission mode determined by the first information; and the OCC sequences or the determined transmission modes used by the two are the same.

[0395] Exemplarily, the first uplink transmission includes UCI and data. The UCI part does not use an OCC sequence or is transmitted in other ways, or the data part is transmitted using an OCC sequence or according to the transmission mode determined by the first information. The UCI part is transmitted in other ways. For example, the UCI can be directly mapped to the transmission resource for transmission without using an OCC sequence for transmission.

[0396] Exemplarily, the first uplink transmission includes UCI and data. The UCI part is transmitted using an OCC sequence or according to the transmission mode determined by the first information, or the data part is transmitted using an OCC sequence or according to the transmission mode determined by the first information; and the OCC sequences or the determined transmission modes used by the two are different.

[0397] Optionally, the terminal performs the first uplink transmission using a first transmission mode, including:

[0398] The terminal determines a first transmission symbol corresponding to the first uplink transmission based on the OCC sequence;

[0399] The terminal transmits the first transmission symbol.

[0400] Wherein, the first transmission symbol can be determined by the bit string corresponding to the first uplink transmission (data or UCI) through the OCC sequence. The terminal transmitting the first transmission symbol may include the terminal modulating the first transmission symbol using π / 2-BPSK to obtain a complex-valued modulation symbol for uplink transmission.

[0401] In addition, determining the first transmission symbol based on the OCC sequence may be obtained by multiplying the bit string corresponding to the first uplink transmission (data or UCI) by the OCC sequence.

[0402] Optionally, the time interval between the first uplink transmission and the reference point includes a first time, and the first time corresponds to the transmission mode of the first uplink transmission or is determined based on the transmission mode of the first uplink transmission.

[0403] Wherein, the reference point may be the time when the downlink control information DCI scheduling the first uplink transmission is located.

[0404] In one implementation, the time interval between the first uplink transmission and the reference point (for example, the time when the DCI corresponding to or scheduling the uplink transmission is located) at least includes: a first time: the first time is related to determining the transmission mode of the first uplink transmission based on the first information or to transmitting based on the determined transmission mode.

[0405] Optionally, the method further includes:

[0406] The terminal reports to the network-side device the supported first time or reports third indication information, where the third indication information is used to indicate whether the time interval between the first uplink transmission and the reference point includes the first time, and the first time corresponds to the transmission mode of the first uplink transmission or is determined based on the transmission mode of the first uplink transmission, and the reference point is the time when the downlink control information DCI scheduling the first uplink transmission is located.

[0407] In one implementation, the UE reports the supported first time or whether the first time is required.

[0408] In one implementation, if the UE does not report the first time, the first time between the first uplink transmission and the reference point is 0, or the first time between the first uplink transmission and the reference point does not need to be included.

[0409] Optionally, the method further includes:

[0410] The terminal receives fourth indication information sent by the network-side device;

[0411] The fourth indication information is used to indicate the transmission mode of the first uplink transmission, or the fourth indication information is used to indicate at least one of the target conditions.

[0412] In this embodiment, the terminal receives the fourth indication information sent by the network-side device, so that the terminal can perform uplink transmission according to the transmission mode of the first uplink transmission indicated by the network-side device, or the terminal can perform uplink transmission based on the target condition indicated by the fourth indication information.

[0413] Optionally, the fourth indication information is used to indicate the part of the first uplink transmission that uses the first transmission mode for transmission; or, the fourth indication information is used to indicate the part of the first uplink transmission that uses the second transmission mode for transmission, and the second transmission mode is different from the first transmission mode.

[0431] Whether the first uplink transmission containing control information uses or does not use the first transmission method for transmission;

[0433] Whether the first uplink transmission containing control information ignores or does not ignore the first information;

[0439] Whether the determination of the transmission method of the control information of the first uplink transmission ignores or does not ignore the first information.

[0440] Optionally, the method further includes:

[0487] The communication operation execution method provided by the embodiments of the present application is described below through several specific embodiments:

[0488] [[ID=3�]]Embodiment 1:

[0490] In an implementation manner, the UE determines the transmission method of the first uplink transmission, including: the UE determines the transmission method of the first uplink transmission based on the first information, and the first uplink transmission needs to satisfy a first condition (or it can be stated that when at least one of the first conditions is satisfied, the UE can determine the transmission method of the first uplink transmission based on the first information), and the first condition includes at least one of the following conditions:

[0501] Optionally, the UE reports: For a maximum value of a certain MCS or a range of MCSs or an MCS table, the UE supports determining the transmission mode of the first uplink transmission based on the first information.

[0503] Optionally, the UE reports: For a maximum value of a certain code rate or a range of certain code rates, the UE supports determining the transmission mode of the first uplink transmission based on the first information.

[0504] e) The first uplink transmission corresponds to a specific modulation method;

[0505] Optionally, the UE reports: For a certain modulation order method, the UE supports determining the transmission mode of the first uplink transmission based on the first information.

[0506] f) The modulation order corresponding to the first uplink transmission is less than or equal to a certain value;

[0507] Optionally, the UE reports: For a maximum value of a certain modulation order or a range of certain modulation orders, the UE determines the transmission mode of the first uplink transmission based on the first information or supports determining the transmission mode of the first uplink transmission based on the first information.

[0509] h) The resource allocation method corresponding to the first uplink transmission is type1 or type2;

[0510] Optionally, the UE reports: for a certain resource allocation method, the UE supports determining the transmission method of the first uplink transmission based on the first information.

[0511] i) The frequency-domain resources corresponding to the first uplink transmission are continuous in the frequency domain;

[0512] For example, the interlace index corresponding to the first uplink transmission is continuous, or the RBs corresponding to the first uplink transmission are continuous.

[0513] j) The SCS corresponding to the first uplink transmission is a specific SCS;

[0514] Optionally, for the first uplink transmission of an idle UE or the first uplink transmission in a specific stage (such as msgA or msg3 in the initial access stage), the specific SCS is 15 kHz or 30 kHz.

[0522] Exemplarily, the first condition includes: the first uplink transmission includes UCI, and the number of resources corresponding to the first uplink transmission cannot exceed a certain value. If the multiplexed PUSCH bandwidth is too large, it may not be possible to ensure that the UCI can be received normally. Therefore, if the PUSCH carries UCI and multiplexing is to be performed, multiplexing can only be supported when the bandwidth is small.

[0523] Alternatively, the first uplink transmission does not include UCI. For example, OCC for PUSCH with UCI is avoided or not desired; exemplarily, the first condition includes: the first uplink transmission does not include UCI. The number of resources corresponding to the first uplink transmission can exceed a certain value.

[0524] p) The number of resources corresponding to the first uplink transmission is an even number or an SF number, or a multiple of SF, where SF is the multiplexing factor or the number of multiplexed users;

[0526] r) The base station has indicated or configured or activated the UE to determine the transmission mode of the first uplink transmission based on the first information;

[0527] It should be noted that corresponding to the above UE reporting, the UE can also report information such as the length, type, index, etc. of the supported first information, such as the OCC length, OCC type, or OCC index.

[0528] It should be noted that corresponding to the above UE reporting, it can be reported per cell, per carrier, per band, per band combination, per BWP, per TDRA table, per Start and length indicator value (SLIV), per time interval K value.

[0529] In one implementation, the UE determines the transmission mode of the first uplink transmission, including: if the second condition is met, the UE does not determine the transmission mode of the first uplink transmission based on the first information (or stated as not performing the first uplink transmission based on the first information; or stated as the transmission mode of the first uplink transmission determined based on the first information is disabled or invalid; or stated as the UE determines the first uplink transmission based on other methods; or stated as determining the transmission mode of the first uplink transmission based on the first information, but at least part of the first information is a specific value, such as the multiplexing user number or multiplexing factor is 1 or the OCC sequence is all 1; or stated as the UE ignores the first information). At this time, the UE performs the transmission of the first uplink transmission (such as PUSCH). Or, if the second condition is met, the UE discards or does not transmit the first uplink transmission.

[0530] The satisfaction of the second condition includes at least one of the following:

[0531] The first uplink transmission does not satisfy at least one of the first conditions; for example, the UE is instructed to use or switch to the CP-OFDM waveform, that is, no longer use the DFT-S-OFDM waveform, then no longer perform uplink transmission based on OCC;

[0532] The base station indicates or configures not to use the first information, or the base station indicates or configures that the first information is deactivated;

[0533] The base station indicates or configures or activates the second transmission mode, or the UE does not determine the transmission mode of the first uplink transmission based on the first information;

[0535] Embodiment 2:

[0536] This embodiment gives the conditions or limitations for multiple UEs to perform uplink transmission based on OCC.

[0537] In this embodiment, the transmission modes of at least two first uplink transmissions are determined based on the first information, and the at least two first uplink transmissions satisfy the sixth condition, and the sixth condition includes at least one of the following:

[0538] a) The time domain resources corresponding to the at least two first uplink transmissions are the same or completely overlapped, or the start point or length or end point of the time domain resources are the same;

[0539] b) The frequency-domain resources corresponding to the at least two first uplink transmissions are the same or completely overlapping, or the starting point or length or ending point of the frequency-domain resources is the same;

[0540] One implementation is that the frequency-domain resources corresponding to the at least two first uplink transmissions are the same, and there is an inclusion relationship between the time-domain resources corresponding to the at least two first uplink transmissions.

[0541] c) The time-domain resources corresponding to the at least two first uplink transmissions are at least partially overlapping or in an inclusion relationship;

[0542] For example, the time-domain resources of one or a certain first uplink transmission include the time-domain resources of another or multiple first uplink transmissions. Further, the time-domain resources corresponding to the at least two first uplink transmissions are in an inclusion relationship, but the corresponding frequency-domain resources do not completely overlap or are not completely included.

[0543] d) The frequency-domain resources corresponding to the at least two first uplink transmissions are at least partially overlapping or in an inclusion relationship.

[0544] For example, the PUSCH resources on the symbols including DMRS in the first uplink transmission do not completely overlap.

[0545] e) The reference signals (such as DMRS) corresponding to the at least two first uplink transmissions are orthogonal.

[0546] The orthogonality can be understood as using the same time-domain or frequency-domain resources, but using different code-domain resources, or using different time-domain or frequency-domain resources.

[0547] f) The reference signals corresponding to the at least two first uplink transmissions overlap or are in an inclusion relationship.

[0548] For example, the time-domain resources of the reference signal of one or a certain first uplink transmission include the time-domain resources of the reference signal of another or multiple first uplink transmissions;

[0549] For example, the frequency-domain resources of the reference signal of one or a certain first uplink transmission include the frequency-domain resources of the reference signal of another or multiple first uplink transmissions.

[0550] g) The number of resources corresponding to the at least two first uplink transmissions is less than or equal to a certain value;

[0575] Exemplarily, the at least two first uplink transmissions all contain UCI, and the number of resources corresponding to the at least two first uplink transmissions cannot exceed a certain value. If the bandwidth of the multiplexed PUSCH is too large, it may not be possible to ensure that the UCI can be received normally. Therefore, if the PUSCH carries UCI and multiplexing is to be performed, multiplexing can only be supported when the bandwidth is small.

[0576] Or, none of the first uplink transmissions contain UCI. Exemplarily, the at least two first uplink transmissions all do not contain UCI, and the number of resources corresponding to the at least two first uplink transmissions can exceed a certain value.

[0580] It should be noted that for the above UE reporting, the UE can also report information such as the length, type, index, etc. of the supported first information, such as the OCC length, OCC type, or OCC index.

[0581] In one implementation, the UE determines the transmission mode of the first uplink transmission, including: if the sixth condition is not satisfied, the UE does not determine the transmission mode of the first uplink transmission based on the first information (or it can be expressed as not performing the first uplink transmission based on the first information; or it can be expressed as the transmission mode of the first uplink transmission determined based on the first information is disabled or invalid; or it can be expressed as the UE determines the first uplink transmission based on other methods; or it can be expressed as determining the transmission mode of the first uplink transmission based on the first information, but at least part of the first information is a specific value, such as the multiplexing user number or multiplexing factor is 1 or the OCC sequence is all 1; or it can be expressed as the UE ignores the first information). At this time, the UE performs the transmission of the first uplink transmission (such as PUSCH). Or, if the fifth condition is satisfied, the first uplink transmission is discarded or not transmitted.

[0582] For example, when the SCSs of at least two first uplink transmissions are different, the first uplink transmission with a lower SCS is not transmitted or the first uplink transmission with a higher SCS is transmitted;

[0583] For example, when the priority indices of at least two first uplink transmissions are different, the first uplink transmission with a lower priority index is not transmitted or the first uplink transmission with a higher priority index is transmitted.

[0584] Embodiment 3:

[0585] This embodiment mainly describes the uplink transmission of PUSCH carrying UCI.

[0586] The UE determines the transmission mode of the first uplink transmission (such as PUSCH) based on the first information, where the first uplink transmission contains UCI, or the first uplink transmission contains UCI and data.

[0587] In one implementation, for the first uplink transmission, the determined transmission mode is used for transmission.

[0588] In one implementation, the first information only targets the data of the first uplink transmission, and the transmission mode of the data of the first uplink transmission is determined based on this first information. Exemplarily, the first information only targets or applies to the data of the first uplink transmission.

[0589] In one implementation, the first information at least includes the first information for the UCI of the first uplink transmission, determines the first information corresponding to the UCI, and determines the transmission mode of the UCI based on this first information. Exemplarily, the first information at least targets or applies to the UCI.

[0590] In one implementation, the first information at least includes the first information for the UCI of the first uplink transmission and the first information for the data of the first uplink transmission, determines the first information corresponding to or applied to the UCI part and the first information corresponding to or applied to the data part, and determines the transmission mode of the UCI and the transmission mode of the data based on the corresponding first information.

[0591] At this time, the first information includes the first information corresponding to or applied to the UCI part and the first information corresponding to or applied to the data part.

[0592] In one implementation, the first information corresponding to the UCI part and the first information corresponding to the data part are at least partially different.

[0593] In one implementation, the base station may indicate or configure at least one of the following, and the UE determines the transmission mode of the first uplink transmission according to the base station indication:

[0594] Whether the first uplink transmission including the UCI determines the transmission mode based on the first information or uses the first information or ignores the first information; Exemplarily, the base station may indicate or configure whether the PUSCH with UCI is to use OCC, or whether the UCI part is to use OCC;

[0595] Whether the UCI part determines the transmission mode based on the first information or uses the first information or ignores the first information.

[0596] In one implementation, if the first uplink transmission includes UCI, the first uplink transmission or at least the UCI part in the first uplink transmission does not determine the transmission mode based on the first information or does not use the first information or ignores the first information, or the transmission mode determined based on the first information is deactivated (or stated as not performing the first uplink transmission based on the first information; or stated as the transmission mode of the first uplink transmission determined based on the first information is disabled or invalid; or stated as the UE determines the first uplink transmission based on other methods; or stated as determining the transmission mode of the first uplink transmission based on the first information, but at least part of the first information is a specific value, such as the multiplexing user number or multiplexing factor is 1 or the OCC sequence is all 1; or stated as the UE ignores the first information). At this time, the UE performs the transmission of the first uplink transmission (such as PUSCH). Or, if the first uplink transmission includes UCI, the UE discards or does not transmit the first uplink transmission.

[0597] Furthermore, it is not expected that this first uplink transmission overlaps with other first uplink transmissions (If UCI is multiplexed, this PUSCH is not expected to apply OCC, this PUSCH should not overlap with other PUSCH).

[0598] In one embodiment, if the first uplink transmission overlaps with other transmissions (such as PUCCH, SR, RS, downlink, etc.), then:

[0599] It is possible to first determine whether to transmit the first uplink transmission based on the first uplink transmission and other transmissions, or the UCI carried on the first uplink transmission (i.e., first apply the UCI multiplexing rule); then determine the transmission mode of the first uplink transmission.

[0600] Exemplarily, the first uplink transmission includes UCI and data. The UCI part is transmitted using the transmission mode corresponding to OCC or the transmission mode determined according to the first information, or the data part is transmitted using the transmission mode corresponding to OCC or the transmission mode determined according to the first information; and the transmission modes corresponding to OCC or the determined transmission modes used by both are the same.

[0601] Exemplarily, the first uplink transmission includes UCI and data. The UCI part does not use the transmission mode corresponding to OCC or is transmitted in other ways, or the data part is transmitted using the transmission mode corresponding to OCC or the transmission mode determined according to the first information. The UCI part is transmitted in other ways, such as: the UCI can be directly mapped to the transmission resource for transmission without using the transmission mode corresponding to OCC for transmission.

[0602] Exemplarily, the first uplink transmission includes UCI and data. The UCI part is transmitted using the transmission mode corresponding to OCC or the transmission mode determined according to the first information, or the data part is transmitted using the transmission mode corresponding to OCC or the transmission mode determined according to the first information; and the transmission modes corresponding to OCC or the determined transmission modes used by both are different.

[0603] Embodiment 4:

[0604] If the first uplink transmission is transmitted using the first mode, and the first mode is modulation using π / 2 - BPSK. Then the method further includes: the determination method of the information of the first uplink transmission (in a certain physical layer process) is as follows:

[0605] For example, the bit string corresponding to the first uplink transmission (data or UCI) is represented as b, and b(i) is the i-th bit among them. Determine the complex-valued modulation symbol d(i) based on b(i). Specifically, the method is as follows:

[0606]

[0607] or

[0608]

[0609] where x is determined by b through OCC or the first information. For example, x is the bit string obtained after b is spread spectrum by OCC, and x(k) is the k-th bit therein. Here, k can be i, that is, the same parameter. At this time, the above formula becomes:

[0610]

[0611] k can also be a parameter related to i, such as a value calculated based on i, or i is calculated based on k. This embodiment does not limit it.

[0612] Embodiment 5:

[0613] In this embodiment, the imaginary unit in the OCC base sequence or the OCC sequence is represented by i, and i can also be replaced by j.

[0614] This embodiment gives an example of the uplink transmission of the terminal based on the OCC sequence in at least one target block:

[0615] Assume that 4 UEs are multiplexed on the same 2 consecutive Physical Resource Blocks (PRBs). Taking the operation of the frequency-domain signal on the l-th symbol as an example, the operation of the frequency-domain signal on the l-th symbol is as follows:

[0616] If the first information indicates that the size of the target block is 1RB = 12REs = 12SCs, then: these 2 PRBs are divided into 2 target blocks. The first target block occupies the first PRB, and the second target block occupies the second PRB;

[0617] Since the number of multiplexed users is 4, the OCC length is configured to 4. Therefore, an OCC base sequence with a length of 4 is selected. For example:

[0618] <![CDATA n > <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 +i -1 -i] 2 [+1 -1 +1 -1] 3 [+1 -i -1 +i]

[0619] UE1 is indicated that OCC index = 0, that is, the OCC base sequence used is [+1 +1 +1 +1];

[0620] UE2 is indicated that OCC index = 1, that is, the OCC base sequence used is [+1 +i -1 -i];

[0621] UE3 is indicated that OCC index = 2, that is, the OCC base sequence used is [+1 -1 +1 -1];

[0622] UE4 is indicated that OCC index = 3, that is, the OCC base sequence used is [+1 -i -1 +i].

[0623] Further, the determined OCC sequences used by 4 users within the target block are as follows:

[0624] The OCC sequence used by UE1 is [+1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1];

[0625] The OCC sequence used by UE2 is [+1 +1 +1 +i +i +i -1 -1 -1 -i -i -i];

[0626] The OCC sequence used by UE3 is [+1 +1 +1 -1 -1 -1 +1 +1 +1 -1 -1 -1];

[0627] The OCC sequence used by UE4 is [+1 +1 +1 -i -i -i -1 -1 -1 +i +i +i].

[0628] Correspondingly,

[0629] The complex-valued modulation symbols transmitted by UE1 within the first target block and the second target block are [x1, x2, x3] and [x4, x5, x6] respectively;

[0630] The complex-valued modulation symbols transmitted by UE2 within the first target block and the second target block are [y1, y2, y3] and [y4, y5, y6] respectively;

[0631] The complex-valued modulation symbols transmitted by UE3 within the first target block and the second target block are [z1, z2, z3] and [z4, z5, z6] respectively;

[0632] The complex-valued modulation symbols transmitted by UE4 within the first target block and the second target block are [w1, w2, w3] and [w4, w5, w6] respectively.

[0633] Then, after each target block independently undergoes transmission precoding or pre-DFT transformation, the complex-valued symbols mapped in the frequency domain within each target block are obtained. The complex-valued symbols after transmission precoding or pre-DFT transformation corresponding to UE1 to UE4 are as follows:

[0634] The complex-valued symbols within the first target block are respectively: [XX1, YY1, ZZ1, WW1, XX2, YY2, ZZ2, WW2, XX3, YY3, ZZ3, WW3];

[0635] The complex-valued symbols within the second target block are respectively: [XX4, YY4, ZZ4, WW4, XX5, YY5, ZZ5, WW5, XX6, YY6, ZZ6, WW6].

[0636] The illustrated process is asFigure 6a , Figure 6b , Figure 6c and Figure 6d as shown

[0637] After the above OCC transmission scheme is applied to these 4 UEs, the frequency-domain signals mapped to the frequency-domain resources on these 2 PRBs at the l-th symbol are as Figure 6e shown<D <D
