[0097] For ease of understanding, some of the contents involved in the embodiments of this application are explained below:

[0098] 1. NTN

[0099] Non-Terrestrial Networks (NTNs) can enhance uplink capacity, for example, by enhancing the DFT-s-OFDM PUSCH with orthogonal cover codes (OCC) to increase capacity or throughput. Furthermore, factors such as Doppler, time variation, and phase distortion under actual deployment conditions must be considered to achieve capacity improvement.

[0100] 2. Block-wise spreading

[0101] In order to improve the multiplexing capability of User Equipment (UE) and thus increase system capacity, a block-wise spreading transmission method based on OCC (orthogonal cover code) is introduced in PUCCH transmission.

[0102] The block-wise spreading scheme is as follows:

[0103] For PUCCH format 3 with interlaced mapping and PUCCH format 4, block-wise spreading shall be applied according to

[0104] where

[0105] For PUCCH format 3 with interleaved mapping, if a single interleaving is configured, then And if two interleavings 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);

[0106] For PUCCH format 4, Given by clause 9.2.1 of [5, TS 38.213], 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);

[0107] And w n Given in 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]. 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 ).

[0108] when Orthogonal sequence w for PUCCH format 3 and PUCCH format 4 with staggered mapping n (m)(Orthogonal sequences w n (m)for PUCCH format 3 with interlaced mapping and PUCCH format 4 when ) are shown in the following table:

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

[0110] For PUCCH format 3, block-wise spreading transmission is supported only when interlace mapping is configured, and multiplexing of 1 / 2 / 4 users is supported only when single interlace is configured;

[0111] For PUCCH format 4, multiplexing of 2 / 4 users is supported and is configured through the higher-layer parameter occ-Length.

[0112] From the above formula, we can see that

[0113] (1) The addition of block-wise spreading is reflected in the frequency domain. For the time domain, the OCC sequence (w_n) multiplied by each symbol is the same;

[0114] (2) By It can be seen that in the frequency domain, These consecutive subcarriers are multiplied by are the same, that is, these consecutive subcarriers can be understood as a block.

[0115] (3) The above blocks are divided according to the total number of subcarriers corresponding to the transmission bandwidth allocated to the uplink channel, that is, the number of blocks is equal to the total number of subcarriers divided by the number of multiplexed users.

[0116] (4) The maximum number of multiplexed users is 4.

[0117] (5) Only users allocated the same RB can be multiplexed together.

[0118] In addition, the principle of block-wise spreading can be understood through the following process:

[0119] To 2 UE multiplexing, for UE 0 and UE 1 are: S0 = a0, a1, ..., a 59 ,a0,a1,…,a 59 ;

[0120] and S1=b0,b1,…,b 59,-b0,-b1,…,-b 59 .

[0121] 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:

[0122] Given a discrete-time signal x n , where n = 0,…,N-1, x n The FFT of is given by n where n=0,…,N-1,the FFT of x n is given by):

[0123] If x n =x n+N / 2 , as in the signal from UE 0 (Now, if x n =x n+N / 2 ,as in the signal from UE 0),

[0124] Obviously, when k is odd, X k =0.

[0125] Similarly, if x n =-x n+N / 2 , as in the signal from UE 1 (Similarly, if x n =-x n+N / 2 ,as in the signal from UE 1),

[0126] Therefore, in this case, when k is even, X k =0.

[0127] Based on the above analysis, we can conclude that the pre-DFT-OCC user multiplexing is equivalent to the comb-based user multiplexing.

[0128] To multiplex four UEs, the Fourier basis can be used for the OCC spreading codes: [1, 1, 1, 1], [1, j, -1, -j], [1, -1, 1, -1], [1, -j, -1, j]. Then, using the same verification as above, it can be shown that the UE performs FDM on every four REs, so the orthogonality between the UEs is maintained regardless of the delay spread of the channel. Therefore, for OCC, 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).

[0129] As can be seen from the above principle, for block-wise spreading, different UEs are multiplied by different OCC sequences, and then the characteristics of FFT transformation are utilized. After pre-DFT transformation, different UEs occupy different REs during frequency domain mapping. For example, UE0 occupies odd REs and UE1 occupies even REs, thereby achieving the effect of comb mapping and realizing multi-user multiplexing.

[0130] An example of a block-wise spreading scheme is as follows:

[0131] Assuming that four users are multiplexed and each user is allocated 2 RBs of bandwidth, the changes before and after pre-DFT are shown in Figures 2a, 2b, 2c, and 2d.

[0132] 3. Determination of TBS

[0133] The TBS of PUSCH is calculated based on the following parameters:

[0134] Available resources: number of allocated time domain symbols, number of allocated frequency domain PRBs;

[0135] The modulation order Q corresponding to the MCS level m , target bit rate R;

[0136] Number of layers υ.

[0137] The calculation process of TBS is as follows:

[0138] Step 1: Calculate the number of available REs

[0139] (1) Calculate the number of available REs in a PRB: in Indicates that a PRB in the frequency domain contains 12 subcarriers; is the number of PUSCH symbols scheduled in a time slot; The overhead of DMRS in one PRB; It is configured by the xOverhead field in the high-level parameter PUSCH-ServingCellConfig, taking into account the overhead of CSI-RS, CORESET, etc. The default value is 0, and the configurable value is {6, 12, 18}. For Msg3 PUSCH transmission, Set to 0.

[0140] (2) Calculate the total number of REs available for configured PUSCH transmission: N RE =min(156,N' RE )·n PRB , where n PRB is the number of PRBs allocated to the UE

[0141] Step 2: Calculate the number of intermediate information bits: N info =N RE ·R·Q m ·υ

[0142] When N info When ≤3824, use Step 3;

[0143] Otherwise, go to Step 4.

[0144] Step 3: When N info ≤3824,

[0145] (1) Quantization of the number of intermediate information bits in

[0146] (2) Find the number of cells that is not less than N' in Figure 3. info Figure 3 shows the nearest TBS of N info TBS below 3824.

[0147] Step 4: When N info >3824 hours,

[0148] Quantified intermediate number in,

[0149] If the target bit rate R≤1 / 4,

[0151] Otherwise (R>1 / 4),

[0152] If N′ info >8424, in

[0153] otherwise,

[0154] The following, in conjunction with the accompanying drawings, describes in detail the communication operation execution method, information receiving method, apparatus and related equipment provided in the embodiments of the present application through some embodiments and their application scenarios.

[0155] 4 is a flow chart of a method for executing a communication operation according to an embodiment of the present application. As shown in FIG4 , the method for executing a communication operation includes the following steps:

[0156] Step 101: The terminal performs a first operation;

[0157] The first operation includes at least one of the following:

[0158] The terminal determines a transmission mode of the first uplink transmission based on the first information;

[0159] The terminal determines, based on information included in the first uplink transmission, a transmission mode of the first uplink transmission;

[0160] The terminal determines a transmission mode of the first uplink transmission based on the target condition;

[0161] The terminal uses the first transmission mode to transmit the first uplink transmission;

[0162] The first transmission mode is 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.

[0163] 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 is not limited to this.

[0164] The first information may include at least one of the following:

[0165] Related information of the target block; OCC configuration information.

[0166] In one embodiment, the relevant information of the target block may include at least one of the following:

[0167] The size of the target block; the number of the target blocks; the bitmap information of the target block; the position information of the target block; the number of the target block; the enabling information of the target block;

[0168] The bitmap information of the target block is used to determine whether the OCC sequence is enabled to be applied in the target block.

[0169] The enabling information of the target block may indicate whether the target block is enabled.

[0170] It should be noted that the target block in the at least one target block is only a pseudonym, which represents a set of resources 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.

[0171] The size of the target block can be used to determine the resource size occupied by a target block in the frequency domain. The data of at least one user (i.e., terminal) can be multiplexed in a target block, and each target block performs an independent DFT transform (such as transmission precoding or pre-DFT transform).

[0172] In addition, the size of the target block can be in units of resource elements (REs) or subcarriers (subcarriers), or in units of RBs, or in units of resource element groups (REGs). For example, for the Internet of Things (IoT), scheduling can be based on single tone or multi-tones, so the target block size can be less than 1RB. For NR, the frequency domain resources scheduled are based on RBs as the basic granularity, so the target block size can be greater than or equal to 1RB.

[0173] In addition, the size of the target block can be indicated separately, or in conjunction with the frequency domain resource allocation (FDRA), or it can be specified by the protocol, or implicitly determined by other indication information, such as the number of users or user groups multiplexed on the target block by the frequency domain resources and OCC length.

[0174] In one embodiment, the target block size, the target number of blocks, and the allocated resources satisfy the following relationship: target block size * target number of blocks = frequency domain resources (number of RBs, number of REs, or number of subcarriers) or transmission bandwidth allocated for uplink transmission (the number can be expressed in terms of number of REs or number of subcarriers, as long as the same granularity is maintained between the variables).

[0175] In addition, based on the size of the target block and in combination with the frequency domain resources allocated by FDRA, the number of target blocks may also be determined.

[0176] It should be noted that the number of target blocks indicates how many target blocks the frequency domain resources allocated by FDRA are divided into, and indirectly determines the size of the target blocks.

[0177] In one embodiment, the bitmap of the target block corresponds to the number of target blocks, indicating whether target uplink transmission is enabled for each target block. If disabled, it means that target uplink transmission is not performed, and uplink transmission is performed according to the normal process, or whether target uplink transmission is enabled is realized through special enabling information of the target block. The target uplink transmission is uplink transmission based on the OCC sequence within the at least one target block.

[0178] The location of the target block is determined based on the frequency domain resources allocated by FDRA and the size or number of the target blocks.

[0179] In one implementation, the OCC configuration information may be used to configure at least one of the following:

[0180] OCC base sequence information; OCC index information; OCC length; OCC multiplexing factor.

[0181] The OCC multiplexing factor may represent the number of multiplexed users, for example, how many users can be multiplexed in the target block.

[0182] The OCC base sequence information may include an OCC base sequence set, an OCC base sequence table, an OCC base sequence, or other information used to determine the OCC base sequence.

[0183] The OCC index information may include information for determining the OCC index, such as an OCC index, an OCC index set, or an OCC index table.

[0184] In one implementation, the OCC configuration information may include at least one of the following: an OCC base sequence set or an OCC base sequence, an OCC index or an OCC index set, an OCC length, and an OCC multiplexing factor.

[0185] The OCC index is used to determine which OCC base sequence to select from the OCC base sequence set, and the corresponding OCC base sequence can be obtained from the OCC base sequence set through the OCC index and the OCC length.

[0186] The above OCC index set is used to indicate the OCC indexes used by different streams. For example, the first OCC index in the OCC index set corresponds to the OCC index used by the first stream.

[0187] Among them, different target blocks can indicate different OCC indexes.

[0188] The OCC length is the length of an OCC base sequence and can be determined by the maximum number of multiplexed users that can be supported in the target block.

[0189] In one implementation, the OCC sequence may be obtained by performing a first operation based on an OCC base sequence and the size of the target block.

[0190] In one implementation, the OCC sequence may be obtained by performing a first operation on an OCC base sequence corresponding to a size of a target block.

[0191] The OCC base sequence may be the OCC base sequence carried by the first information, or may be an OCC sequence in related technologies, such as OCC2 or OCC4.

[0192] OCC2 is shown in the following table:

[0193] OCC4 is shown in the following table:

[0194] 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.

[0195] It should be noted that the target block size 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 target block size is 2RB=24REs and the OCC base sequence is: [1 1i -1 -1i], then after applying the first operation, the OCC sequence used in the target block is: [1 1 1 1 1 1i 1i 1i 1i 1i 1i-1 -1 -1 -1 -1 -1 -1i -1i -1i -1i -1i -1i].

[0196] 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 an OCC sequence based on the first information, and transmits the first uplink transmission based on the OCC sequence.

[0197] Among them, the terminal adopts the first transmission mode to perform the first uplink transmission, which may include: the terminal performs uplink transmission based on the OCC sequence in at least one target block, and the OCC sequence corresponding to the at least one target block is the same; or when the first uplink transmission is PUSCH, the terminal performs uplink transmission through block-wise spreading based on OCC. The OCC-based block-wise spreading implementation of PUSCH is similar to the OCC-based block-wise spreading implementation of PUCCH in the related art, and will not be repeated here.

[0198] It should be noted that the target block can also be described as a block, or a multiplexed block, etc. The OCC sequence corresponding to the at least one target block is the same, which can be understood as the OCC sequence used in different target blocks for the same transmission of the same terminal is the same.

[0199] It should be noted that the first uplink transmission can be understood as uplink resources.

[0200] Among them, the first uplink transmission may include physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission, physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission, or narrowband physical uplink shared channel (Narrowband Physical Uplink Shared Channel, NPUSCH) transmission, etc., which is not limited in this embodiment.

[0201] In one implementation, the first uplink transmission may be a PUSCH.

[0202] In one embodiment, the UE determines that at least a portion of the first uplink transmission is not transmitted based on the transmission mode of the first uplink transmission determined by the first information or is transmitted using another mode. When generating or processing a bit stream corresponding to at least a portion of the first uplink transmission, the corresponding OCC is an all-ones sequence, or operations related to the OCC are skipped. Another mode may be a transmission mode that directly maps the information to be transmitted to a transmission resource for transmission.

[0203] In one embodiment, the UE determines a transmission mode of the first uplink transmission based on at least part of the first information, and when generating or processing a bit stream corresponding to at least part of the first uplink transmission, the corresponding OCC is a sequence determined based on the first information.

[0204] In one embodiment, the terminal adopting the first transmission mode to perform the first uplink transmission may include, the terminal performing the uplink transmission based on the OCC sequence within at least one target block. The terminal performing the uplink transmission based on the OCC sequence within at least one target block includes:

[0205] The terminal multiplies the transmission symbol mapped in each target block of the at least one target block by the OCC sequence to obtain a first transmission symbol corresponding to each target block;

[0206] The terminal performs discrete Fourier transform (DFT) processing on the first transmission symbol corresponding to each target block to obtain a second transmission symbol corresponding to each target block;

[0207] The terminal performs uplink transmission based on the second transmission symbol corresponding to each target block.

[0208] The DFT transform processing may include DFT transform processing corresponding to transmission precoding, for example, Pre-DFT transform. Pre-DFT transform may also be described as transmission precoding transform.

[0209] Among them, the transmission symbol can refer to the complex-valued constellation point symbol after modulation, and the physical layer process from modulation to resource mapping is all processed in the form of transmission symbols (or described as symbol-level processing or non-bit-level processing).

[0210] In one embodiment, uplink transmission based on the OCC sequence in the target block may be performed by multiplying the transmission symbols mapped in the target block by the OCC sequence, performing pre-DFT transformation or transmission precoding, and obtaining transmission symbols before frequency domain mapping.

[0211] For example, let's take a formula similar to format 4.

[0212] Assume that d(0),…,d(M symb -1) is the replicated modulation symbol before the uplink transmission operation based on the OCC sequence in the target block, y(0),…,y(M symb L-1) represents the replicated modulation symbol before pre-DFT transformation or transmission precoding.

[0213] In one embodiment, for the target block #i on symbol #1, the transmission symbol mapped in the target block is multiplied by the OCC sequence, corresponding to the following formula:

[0214] in:

[0215] i=0,1,…,M block -1;

[0216] l=0,1,…,(M symb L / M sc )-1;

[0217] M sc Indicates the number of subcarriers or REs corresponding to the frequency domain resources allocated for uplink transmission;

[0218] M symb Indicates the number of replicated modulation symbols that can be transmitted in the uplink transmission;

[0219] M block Indicates the number of target blocks (within the bandwidth / frequency domain resources allocated for uplink transmission);

[0220] Indicates the size of the target block, in units of RE or number of subcarriers;

[0221] L represents the OCC length or multiplexing factor;

[0222] Indicates the number of complex-valued modulation symbols transmitted within a target block;

[0223] n is determined by the OCC index, w n represents an OCC base sequence;

[0224] satisfy:

[0225] In one embodiment, for the entire uplink transmission (including all scheduled time domain symbols, i.e., l = 0, 1, ..., (M symb L / M sc )-1):

[0226] in:

[0227] k=0,1,…,M sc -1; l=0,1,…,(M symb L / M sc )-1;

[0228] M sc Indicates the number of subcarriers or REs corresponding to the frequency domain resources allocated for uplink transmission;

[0229] M symb Indicates the number of replicated modulation symbols that can be transmitted in uplink transmission;

[0230] M block Indicates the number of target blocks (within the bandwidth or frequency domain resources allocated for uplink transmission);

[0231] Indicates the size of the target block, in units of RE or number of subcarriers;

[0232] L represents the OCC length or multiplexing factor;

[0233] Indicates the number of complex-valued modulation symbols transmitted within a target block;

[0234] n is determined by the OCC index, w n represents an OCC base sequence;

[0235] satisfy:

[0236] It can be seen from the above formula that the number of complex-valued symbols needs to be scaled to a certain extent compared to the normal uplink transmission process.

[0237] In one embodiment, the terminal adopts the first transmission mode to perform the first uplink transmission, which may include: the terminal maps the transmission symbol to the first transmission unit in at least one target block; the terminal performs uplink transmission based on the first OCC sequence in the at least one target block; wherein the transmission symbol is mapped to the first transmission unit through the second OCC sequence, or the first OCC sequence corresponding to the at least one target block is the same. The first information may also include relevant information of the first transmission unit, and the relevant information of the first transmission unit includes at least one of the following: the size of the first transmission unit; the number of the first transmission units; the position of the first transmission unit; the number of the first transmission unit. wherein a target block may contain one or more first transmission units, and the size, number, position or number of the first transmission unit is defined in a target block; or one or more first transmission units are divided in a target block.

[0238] It should be noted that the first transmission unit is only a pseudonym for some resource sets obtained by dividing 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.

[0239] In one implementation, mapping, by the terminal, the transmission symbol to the first transmission unit in at least one target block may include any one of the following:

[0240] The terminal multiplies the transmission symbol mapped by the first transmission unit in at least one target block by the corresponding second OCC sequence to obtain a third transmission symbol, and transforms the first transmission symbol to obtain a fourth transmission symbol corresponding to the first transmission unit;

[0241] The terminal maps the transmission symbol mapped by the first transmission unit in at least one target block to the first transmission unit in a first mapping manner;

[0242] The first mapping method includes at least one of the following:

[0243] Sub-PRB mapping; single tone mapping; multi-tones mapping; comb mapping; interlace mapping.

[0244] In one embodiment, the terminal multiplies a transmission symbol mapped by a first transmission unit in at least one target block by a corresponding second OCC sequence to obtain a third transmission symbol, and transforms the first transmission symbol to obtain a fourth transmission symbol y corresponding to the first transmission unit. This is implemented as follows:

[0245] Assumptions is a replica modulation symbol before an uplink transmission operation is performed based on the second OCC sequence in the first transmission unit, y(0),…,y(L-1) represent replica modulation symbols before pre-DFT transformation;

[0246] For the first transmission unit #i on symbol #1, the transmission symbol mapped in the first transmission unit is multiplied by the second OCC sequence, corresponding to the following formula:

[0247] in:

[0248] i=0,1,…,M block -1;

[0249] M blockIndicates the number of first transmission units in a target block;

[0250] Indicates the size of the target block, in units of RE or number of subcarriers;

[0251] L represents the OCC length or multiplexing factor;

[0252] represents the number of complex-valued modulation symbols transmitted for the current UE in a first transmission unit;

[0253] n is determined by the OCC index, w n represents the second OCC base sequence;

[0254] The first transmission unit #i is the first transmission unit number or index corresponding to the current terminal.

[0255] In addition, after multiplying the corresponding second OCC sequence in the first transmission unit, the mapping to the corresponding transmission resource through pre-DFT transformation is implemented as follows:

[0256] After the pre-DFT transformation, y(0),…,y(L-1) becomes Y(0),…,Y(L-1), and Y(0),…,Y(L-1) is mapped to the transmission resource corresponding to the first transmission unit, thereby obtaining the complex-valued transmission symbol before the target block performs uplink transmission based on the first OCC sequence.

[0257] It should be noted that the implementation of the terminal performing uplink transmission based on the first OCC sequence in the at least one target block is similar to the aforementioned implementation of the terminal performing uplink transmission based on the OCC sequence in the at least one target block, which will not be repeated here.

[0258] In one implementation, the UE determines whether to determine a transmission mode of the first uplink transmission based on the first information.

[0259] In NTN scenarios, due to the large coverage area and the potential for a large number of concurrently connected users, capacity enhancement of the uplink channel is required to increase system capacity and enhance uplink user multiplexing. Since NTN scenarios only support single-layer transmission, and DMRS ports already support multi-port multiplexing, capacity enhancement of the data portion of the uplink channel is required. In this embodiment of the present application, the terminal uses a first transmission mode for a first uplink transmission, performs uplink transmission using an OCC sequence, and implements multi-user OCC multiplexing, addressing the aforementioned limitations.

[0260] It should be noted that the embodiments of the present application are applicable to NTN scenarios, but are not limited to NTN scenarios, and are also applicable to TN scenarios.

[0261] The embodiments of the present application are not only applicable to NR systems, but also to LTE NB-IoT or IoT NTN systems, etc.

The base station may indicate at least a portion of the first uplink transmission, and the portion indicated by the base station may require determining a transmission mode based on the first information, or may not require determining a transmission mode based on the first information.

[0355] 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 the OCC, and the transmission of the data part uses the transmission method corresponding to the 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 the OCC, or which parts do not need to use the transmission method corresponding to the OCC.

[0356] For example, the base station indicates a set that includes at least one item of {UCI, data}. If the set includes UCI and data, it means that the transmission of UCI and data must use the transmission method corresponding to the OCC. If only data is included, it means that only the transmission of data needs to use the transmission method corresponding to the OCC.

[0357] For example, UCI or data has corresponding enabling information. If the base station provides the enabling information or sets the enabling information to enable, it means that the transmission of UCI or data uses the transmission method corresponding to OCC. The UCI and data parts can uniformly use one enabling information, or the two can correspond to one enabling information respectively.

[0358] For example, UCI or data has corresponding disabling information. If the base station provides the disabling information or sets the disabling information to disable, it means that the transmission of UCI or data does not use the transmission method corresponding to OCC or is based on other transmission methods. The UCI and data parts can uniformly use one disabling information, or the two can correspond to one disabling information respectively.

[0359] It should be noted that when the base station indicates to the terminal which part of the bits uses the transmission method corresponding to the OCC or which part of the bits does not use the transmission method corresponding to the OCC, it can indicate the starting point, length, end point, corresponding position or number of the part; when the base station indicates to the terminal which part of the resources uses the transmission method corresponding to the OCC or which part of the resources does not use the transmission method corresponding to the OCC, it can indicate the starting point, length, end point, corresponding position or number of the resources.

[0360] In this embodiment, the terminal receives the second indication information sent by the network side device, so that it 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.

[0361] Optionally, the first information corresponding to the control information of the first uplink transmission is at least partially different from the first information corresponding to the data of the first uplink transmission.

[0362] Optionally, when the first uplink transmission includes control information, the terminal determines, based on the information included in the first uplink transmission, a transmission mode of the first uplink transmission, including at least one of the following:

[0363] The terminal determines that the transmission mode of the control information is a second transmission mode, where the second transmission mode is different from the first transmission mode;

[0364] 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;

[0365] Determining, by the terminal, that a transmission mode of the first uplink transmission is a second transmission mode, where the second transmission mode is different from the first transmission mode;

[0366] 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;

[0367] The terminal determines that the first uplink transmission or the transmission of the control information does not use the first information;

[0368] The terminal determines that the first uplink transmission or the transmission of the control information ignores the first information;

[0369] The terminal determines that the first uplink transmission or the transmission of the control information is deactivated in the first transmission mode;

[0370] The terminal does not perform the first uplink transmission.

[0371] In related technologies, block-wise spreading transmission modes similar to PUCCH format 4 utilize OCC sequences to achieve multi-user multiplexing. When using OCC sequences for uplink transmissions (such as PUSCH) with multi-user multiplexing, the implementation methods may differ. Taking the first uplink transmission as PUSCH as an example, when the first uplink transmission includes control information (such as UCI), the terminal may determine the transmission mode of the first uplink transmission based on the information included in the first uplink transmission.

[0372] 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.

[0373] 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:

[0374] Determining, by the terminal, whether to transmit the first uplink transmission based on the first uplink transmission and the second uplink transmission;

[0375] Determining, by the terminal, control information carried by the first uplink transmission based on the first uplink transmission and the second uplink transmission;

[0376] The second uplink transmission is an uplink transmission other than the first uplink transmission.

[0377] In the case where the first uplink transmission overlaps with the second uplink transmission, whether to transmit the first uplink transmission or the UCI carried on the first uplink transmission can be determined based on the first uplink transmission and the second uplink transmission; and then the transmission mode of the first uplink transmission is determined.

[0378] For example, the first uplink transmission includes UCI and data, the UCI part is transmitted using the OCC sequence or according to the transmission method determined by the first information, or the data part is transmitted using the OCC sequence or according to the transmission method determined by the first information; and the OCC sequence or determined transmission method used by both are the same.

[0379] For example, the first uplink transmission includes UCI and data. The UCI portion is not transmitted using an OCC sequence or is transmitted in another manner, or the data portion is transmitted using an OCC sequence or in a transmission manner determined by the first information. The UCI portion is transmitted in another manner, for example, by directly mapping the UCI to a transmission resource for transmission without using an OCC sequence.

[0380] For example, the first uplink transmission includes UCI and data, the UCI part is transmitted using the OCC sequence or according to the transmission method determined by the first information, or the data part is transmitted using the OCC sequence or according to the transmission method determined by the first information; and the OCC sequences or determined transmission methods used by the two are different.

[0381] Optionally, the terminal adopting the first transmission mode to perform the first uplink transmission includes:

[0382] Determining, by the terminal, a first transmission symbol corresponding to the first uplink transmission based on the OCC sequence;

[0383] The terminal transmits the first transmission symbol.

[0384] The first transmission symbol may be determined by a bit string corresponding to a first uplink transmission (data or UCI) through an 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.

[0385] In addition, the first transmission symbol may be determined based on the OCC sequence, and may be obtained by multiplying a bit string corresponding to the first uplink transmission (data or UCI) by the OCC sequence.

[0386] Optionally, the time interval between the first uplink transmission and the reference point includes a first time, the first time corresponds to a transmission mode of the first uplink transmission, or the first time is determined based on the transmission mode of the first uplink transmission.

[0387] The reference point may be the time at which the downlink control information DCI for scheduling the first uplink transmission is located.

[0388] In one embodiment, the time interval between the first uplink transmission and the reference point (for example, the time corresponding to or scheduling the DCI of the uplink transmission) includes at least: the first time: the first time is related to the transmission mode of the first uplink transmission determined based on the first information, or is related to the transmission based on the determined transmission mode.

[0389] Optionally, the method further includes:

[0390] The terminal reports a supported first time to the network side device, 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, the first time corresponds to the transmission mode of the first uplink transmission, or the first time is determined based on the transmission mode of the first uplink transmission, and the reference point is the time at which the downlink control information DCI for scheduling the first uplink transmission is located.

[0391] In one implementation, the UE reports the supported first time, or whether the first time is required.

[0392] 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 does not need to be included between the first uplink transmission and the reference point.

[0393] Optionally, the method further includes:

[0394] The terminal receives fourth indication information sent by the network side device;

[0395] The fourth indication information is used to indicate a transmission mode of the first uplink transmission, or the fourth indication information is used to indicate at least one of the target conditions.

[0396] 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 first uplink transmission mode indicated by the network side device, or the terminal can perform uplink transmission based on the target condition indicated by the fourth indication information.

[0397] Optionally, the fourth indication information is used to indicate the part of the first uplink transmission that is transmitted using a first transmission mode; or, the fourth indication information is used to indicate the part of the first uplink transmission that is transmitted using a second transmission mode, and the second transmission mode is different from the first transmission mode.

[0471] The following describes the communication operation execution method provided by the embodiment of the present application through several specific embodiments:

[0472] Example 1:

[0473] This embodiment provides conditions or restrictions for a single UE when performing uplink transmission based on the OCC.

[0474] In one embodiment, the UE determines a transmission mode of a first uplink transmission, including: the UE determines the transmission mode of the first uplink transmission based on first information, the first uplink transmission needs to satisfy a first condition (or stated as, when at least one of the first conditions is satisfied, the UE can determine the transmission mode of the first uplink transmission based on the first information), and the first condition includes at least one of the following conditions:

[0475] a) the number of resources corresponding to the first uplink transmission is less than or equal to a certain value;

[0476] For example, the number of time domain resources corresponding to the first uplink transmission is less than or equal to 1;

[0477] For example, the number of frequency domain resources corresponding to the first uplink transmission is less than or equal to 2;

[0478] Or, the number of resources corresponding to the first uplink transmission is greater than or equal to a certain value (similar to PUCCH format 3, whether multi-user multiplexing can be performed is related to the number of interlaces);

[0479] For example, the number of time domain resources corresponding to the first uplink transmission is less than or equal to 3;

[0480] For example, the number of frequency domain resources corresponding to the first uplink transmission is less than or equal to 4;

[0481] Optionally, the UE reports: for a certain maximum number of resources or a certain range of resource numbers, the UE supports determining a transmission mode for the first uplink transmission based on the first information.

[0482] b) the TBS corresponding to the first uplink transmission is less than or equal to a certain value;

[0483] Optionally, the UE reports: for a certain TBS maximum value or a certain TBS range, the UE supports determining a transmission mode for the first uplink transmission based on the first information.

[0484] c) the MCS corresponding to the first uplink transmission is less than or equal to a certain value;

[0485] Optionally, the UE reports: for a certain MCS maximum value or MCS range or MCS table, the UE supports determining a transmission mode for the first uplink transmission based on the first information.

[0486] d) the code rate corresponding to the first uplink transmission is less than or equal to a certain value;

[0487] Optionally, the UE reports: for a certain maximum code rate or code rate range, the UE supports determining a transmission mode for the first uplink transmission based on the first information.

[0488] e) The first uplink transmission corresponds to a specific modulation method;

[0489] Optionally, the UE reports: for a certain modulation order method, the UE supports determining a transmission mode for the first uplink transmission based on the first information.

[0490] f) the modulation order corresponding to the first uplink transmission is less than or equal to a certain value;

[0491] Optionally, the UE reports: for a certain maximum modulation order value or modulation order range, 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.

[0492] g) The first uplink transmission uses a specific waveform (e.g., DFT-S-OFDM);

[0493] h) The resource allocation mode corresponding to the first uplink transmission is type 1 or type 2;

[0494] Optionally, the UE reports: for a certain resource allocation mode, the UE supports determining a transmission mode for the first uplink transmission based on the first information.

[0495] i) the frequency domain resources corresponding to the first uplink transmission are continuous in the frequency domain;

[0496] For example, the interlace indexes corresponding to the first uplink transmission are continuous, or the RBs corresponding to the first uplink transmission are continuous.

[0497] j) The SCS corresponding to the first uplink transmission is a specific SCS;

[0498] Optionally, for the first uplink transmission of an idle UE or the first uplink transmission in a specific phase (such as msgA, msg3 in the initial access phase), the specific SCS is 15kHz or 30kHz.

[0499] Optionally, the UE reports: for which SCSs, the UE supports the transmission method for determining the first uplink transmission based on the first information.

[0500] k) The CP corresponding to the first uplink transmission is a specific CP (e.g., a Normal Cyclic Prefix (NCP));

[0501] Optionally, the UE reports: for which CPs, the UE supports a transmission mode for determining the first uplink transmission based on the first information.

[0502] l) The DC corresponding to the first uplink transmission is located at a specific position (for example, outside the carrier, outside the resources corresponding to the first uplink transmission, or at a certain position indicated or configured by the base station).

[0503] m) The priority index corresponding to the first uplink transmission is a specific priority index (e.g., index=1, or index=0);

[0504] n) There is no priority index corresponding to the first uplink transmission;

[0505] o) The first uplink transmission includes UCI, or includes specific UCI or target information (such as Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) or Scheduling Request (SR));

[0506] For example, 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 properly received. Therefore, if the PUSCH carries UCI and is to be multiplexed, multiplexing can only be supported when the bandwidth is small.

[0507] Alternatively, the first uplink transmission does not include UCI, for example, avoiding or not expecting to perform OCC on a PUSCH with UCI; illustratively, the first condition includes: the first uplink transmission does not include UCI. The number of resources corresponding to the first uplink transmission may exceed a certain value.

[0508] p) The number of resources corresponding to the first uplink transmission is an even number or a number of SFs, or a multiple of SFs, where SF is the multiplexing factor or the number of multiplexed users;

[0509] q) The base station indicates, configures, or activates the first information;

[0510] r) the base station instructs, configures, or activates the UE to determine a transmission mode for the first uplink transmission based on the first information;

[0511] It should be noted that, corresponding to the above UE reporting, the UE may 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.

[0512] It should be noted that, corresponding to the above-mentioned 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), and per time interval K value.

[0513] In one embodiment, 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 expressed as not performing the first uplink transmission based on the first information; or expressed as the transmission mode of the first uplink transmission determined based on the first information is disabled or invalid; or expressed as the UE determines the first uplink transmission based on other methods; or 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 number of multiplexed users or the multiplexing factor is 1 or the OCC sequence is all 1s; or expressed as the UE ignores the first information), at this time, the UE transmits the first uplink transmission (e.g., PUSCH). Alternatively, if the second condition is met, the UE discards or does not transmit the first uplink transmission.

[0514] The second condition includes at least one of the following:

[0515] 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 a CP-OFDM waveform, that is, no longer uses a DFT-S-OFDM waveform, and then no longer performs uplink transmission based on the OCC;

[0516] 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;

[0517] The base station indicates, 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;

[0518] It should be noted that, for the above-mentioned first condition or the above-mentioned UE reporting, the granularity can be reported per (per) cell, per carrier, per band, per band combination, per BWP, per TDRA table, per SLIV, or per time interval K value.

[0519] Example 2:

[0520] This embodiment provides conditions or restrictions for multiple UEs to perform uplink transmission based on the OCC.

[0521] In this embodiment, a transmission mode of at least two first uplink transmissions is determined based on the first information, and the at least two first uplink transmissions satisfy a sixth condition, which includes at least one of the following:

[0523] b) the frequency domain resources corresponding to the at least two first uplink transmissions are the same or completely overlap, or the frequency domain resources have the same starting point, length, or end point;

[0530] The orthogonality may be understood as using the same time domain or frequency domain resources but different code domain resources, or using different time domain or frequency domain resources.

[0531] f) The reference signals corresponding to the at least two first uplink transmissions overlap or are included in each other.

[0532] For example, the time domain resource of one or a certain reference signal of the first uplink transmission includes the time domain resource of one or more other reference signals of the first uplink transmission;

[0533] For example, the frequency domain resources of one or a certain first uplink transmission reference signal include the frequency domain resources of one or more other first uplink transmission reference signals.

[0547] o) the modulation orders corresponding to the at least two first uplink transmissions are both less than or equal to a certain value;

[0548] p) the at least two first uplink transmissions both use a specific waveform (e.g., DFT-S-OFDM);

[0549] q) the resource allocation mode corresponding to the at least two first uplink transmissions is type 1 or type 2; for example, both are type 1 or both are type 2;

[0550] r) the frequency domain resources corresponding to the at least two first uplink transmissions are continuous in the frequency domain;

[0551] For example, interlace indexes corresponding to the at least two first uplink transmissions are continuous, or RBs corresponding to the at least two first uplink transmissions are continuous;

[0552] s) The SCSs corresponding to the at least two first uplink transmissions are the same, or are both specific SCSs;

[0553] t) The CPs corresponding to the at least two first uplink transmissions are the same, or are both specific CPs (eg, NCPs);

[0554] u) the DCs corresponding to the at least two first uplink transmissions are both located at a specific location (e.g., outside the carrier, outside the resources of the first uplink transmission, or at a location indicated or configured by the base station);

[0555] v) the priority indexes corresponding to the at least two first uplink transmissions are both specific priority indexes (eg, index=1, or index=0);

[0556] w) Of the at least two first uplink transmissions, only X first uplink transmissions at most contain UCI or specific UCI; or, neither contains UCI or specific UCI, for example, to avoid or not expect to perform OCC on a PUSCH with UCI;

[0557] x) the at least two first uplink transmissions do not have a corresponding priority index;

[0558] y) the at least two first uplink transmissions both include UCI, or both include specific UCI (such as HARQ-ACK or SR);

[0559] For example, the at least two first uplink transmissions both include UCI, and the number of resources corresponding to the at least two first uplink transmissions cannot exceed a certain value. If the multiplexed PUSCH bandwidth is too large, normal reception of the UCI may not be guaranteed. Therefore, if the PUSCH carries UCI and is to be multiplexed, multiplexing is only supported when the bandwidth is small.

[0560] Alternatively, none of the first uplink transmissions includes UCI. For example, none of the at least two first uplink transmissions includes UCI, and the number of resources corresponding to the at least two first uplink transmissions may exceed a certain value.

[0561] z) the number of resources corresponding to the at least two first uplink transmissions is an even number or a number of SFs, or a multiple of SFs, where SF is a multiplexing factor or the number of multiplexed users;

[0562] aa) the at least two first uplink transmissions are all indicated, configured, or activated by the base station;

[0563] bb) the at least two first uplink transmissions are all indicated by the base station or configured or activated by the UE to determine a transmission mode for the first uplink transmission based on the first information;

[0564] It should be noted that, corresponding to the above UE reporting, the UE may 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.

[0565] In one embodiment, the UE determines the transmission mode of the first uplink transmission, including: if the sixth condition is not met, the UE does not determine the transmission mode of the first uplink transmission based on the first information (or expressed as not performing the first uplink transmission based on the first information; or expressed as the transmission mode of the first uplink transmission determined based on the first information is disabled or invalid; or expressed as the UE determines the first uplink transmission based on other methods; or 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 number of multiplexed users or the multiplexing factor is 1 or the OCC sequence is all 1s; or expressed as the UE ignores the first information), at this time, the UE transmits the first uplink transmission (e.g., PUSCH). Or, if the fifth condition is met, the first uplink transmission is discarded or not transmitted.

[0566] For example, when the SCSs of the 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;

[0567] For example, when the priority indexes of the 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.

[0568] Example 3:

[0569] This embodiment mainly describes uplink transmission of a PUSCH carrying UCI.

[0570] The UE determines a transmission mode of a first uplink transmission (such as a PUSCH) based on the first information, where the first uplink transmission includes UCI, or the first uplink transmission includes UCI and data.

[0571] In one implementation, the first uplink transmission is performed using the above-determined transmission mode.

[0572] In one embodiment, the first information is only for the data of the first uplink transmission, and the transmission mode of the data of the first uplink transmission is determined based on the first information. For example, the first information is only for or applied to the data of the first uplink transmission.

[0573] In one embodiment, the first information at least includes first information for UCI of the first uplink transmission, the first information corresponding to the UCI is determined, and the transmission mode of the UCI is determined based on the first information. For example, the first information at least targets or is applied to the UCI.

[0574] In one embodiment, the first information includes at least first information about UCI for the first uplink transmission and first information about data for 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 method of the UCI and the transmission method of the data based on the corresponding first information.

[0575] 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.

[0576] In one implementation, the first information corresponding to the UCI portion and the first information corresponding to the data portion are at least partially different.

[0577] In one implementation, the base station may instruct or configure at least one of the following, and the UE determines the transmission mode of the first uplink transmission according to the instruction of the base station:

[0578] Whether the first uplink transmission containing UCI determines the transmission mode based on the first information, whether to use the first information, or whether to ignore the first information; for example, the base station can indicate or configure whether the PUSCH with UCI is to use the OCC, or whether the UCI part is to use the OCC;

[0579] The UCI part determines whether the transmission mode is determined based on the first information, whether the first information is used, or whether the first information is ignored.

[0580] In one embodiment, if a first uplink transmission includes UCI, the first uplink transmission, or at least the UCI portion of the first uplink transmission, does not determine a transmission mode based on first information, does not use the first information, or ignores the first information. Alternatively, the transmission mode determined based on the first information is deactivated (or alternatively, the first uplink transmission is not performed based on the first information; or the transmission mode of the first uplink transmission determined based on the first information is disabled or invalidated; or the UE determines the first uplink transmission based on another mode; or the transmission mode of the first uplink transmission is determined based on the first information, but at least a portion of the first information is a specific value, such as the number of multiplexed users or the multiplexing factor being 1, or the OCC sequence being all 1s; or the UE ignores the first information). At this point, the UE transmits the first uplink transmission (e.g., PUSCH). Alternatively, if the first uplink transmission includes UCI, the UE discards or does not transmit the first uplink transmission.

[0581] Furthermore, it is not expected that the 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).

[0582] In one embodiment, if the first uplink transmission overlaps with other transmissions (such as PUCCH, SR, RS, downlink, etc.), then:

[0583] Whether to transmit the first uplink transmission or the UCI carried on the first uplink transmission may be determined based on the first uplink transmission and other transmissions (ie, applying a UCI multiplexing rule first); and then determining a transmission mode for the first uplink transmission.

[0584] For example, the first uplink transmission includes UCI and data, the UCI part is transmitted using the transmission method corresponding to the OCC or the transmission method determined according to the first information, or the data part is transmitted using the transmission method corresponding to the OCC or the transmission method determined according to the first information; and the transmission method corresponding to the OCC or the determined transmission method used by the two are the same.

[0585] For example, the first uplink transmission includes UCI and data. The UCI portion is not transmitted using the transmission mode corresponding to the OCC or is transmitted using another mode, or the data portion is transmitted using the transmission mode corresponding to the OCC or a transmission mode determined according to the first information. The UCI portion is transmitted using another mode, for example, the UCI may be directly mapped to a transmission resource for transmission without using the transmission mode corresponding to the OCC.

[0586] For example, the first uplink transmission includes UCI and data, the UCI part is transmitted using the transmission method corresponding to the OCC or the transmission method determined according to the first information, or the data part is transmitted using the transmission method corresponding to the OCC or the transmission method determined according to the first information; and the transmission methods corresponding to the OCC or the determined transmission methods used by the two are different.

[0587] Example 4:

[0588] If the first uplink transmission is transmitted using a first mode, and the first mode is modulation using π / 2-BPSK, the method further includes: determining information of the first uplink transmission (in a certain physical layer process) in the following manner:

[0589] For example, the bit string corresponding to the first uplink transmission (data or UCI) is represented by b, and b(i) is the i-th bit. The complex-valued modulation symbol d(i) is determined based on b(i). The specific method is:

[0590] or

[0591] or

[0592] Where x is the bit string obtained by OCC or first information after b is spread by OCC, and x(k) is the kth bit in the string. Here, k can be the same as i, that is, the same parameter. In this case, the above formula becomes:

[0593] k may also be a parameter related to i, such as a value calculated based on i, or i may be calculated based on k, which is not limited in this embodiment.

[0594] Example 5:

[0595] In this embodiment, the OCC base sequence or the imaginary unit in the OCC sequence is represented by i, which may also be replaced by j.

[0596] This embodiment illustrates an example of the terminal performing uplink transmission based on the OCC sequence in at least one target block.

[0597] Assuming that four UEs are multiplexed on the same two consecutive physical resource blocks (PRBs), the operation of the frequency domain signal on the lth symbol is illustrated as an example. The operation of the frequency domain signal on the lth symbol is as follows:

[0598] If the first information indicates that the size of the target block is 1RB=12REs=12SCs, then: the two PRBs are divided into two target blocks, the first target block occupies the first PRB, and the second target block occupies the second PRB;

[0599] Since the number of multiplexed users is 4, the OCC length is configured to be 4. Therefore, an OCC base sequence with a length of 4 is selected, for example:

[0600] UE1 is instructed that OCC index = 0, i.e., the OCC base sequence used is [+1 +1 +1 +1];

[0601] UE2 is instructed to use OCC index = 1, that is, the OCC base sequence used is [+1 +i -1 -i];

[0602] UE3 is instructed to use OCC index = 2, that is, the OCC base sequence used is [+1 -1 +1 -1];

[0603] UE4 is instructed that OCC index=3, that is, the OCC base sequence used is [+1 -i -1 +i].

[0604] Furthermore, the OCC sequences used by the four users in the target block are determined as:

[0605] UE1 uses the OCC sequence of [+1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1];

[0606] The OCC sequence used by UE2 is [+1 +1 +1 +i +i +i -1 -1 -1 -i -i -i];

[0607] UE3 uses the OCC sequence of [+1 +1 +1 -1 -1 -1 +1 +1 +1 -1 -1 -1];

[0608] The OCC sequence used by UE4 is [+1 +1 +1 -i -i -i -1 -1 -1 +i +i +i].

[0609] Accordingly,

[0610] The complex-valued modulation symbols transmitted by UE1 in the first target block and the second target block are [x1, x2, x3] and [x4, x5, x6] respectively;

[0611] The complex-valued modulation symbols transmitted by UE2 in the first target block and the second target block are [y1, y2, y3] and [y4, y5, y6] respectively;

[0612] The complex-valued modulation symbols transmitted by UE3 in the first target block and the second target block are [z1, z2, z3] and [z4, z5, z6] respectively;

[0613] The complex-valued modulation symbols transmitted by UE4 in the first target block and the second target block are [w1, w2, w3] and [w4, w5, w6] respectively.

[0614] Then, each target block is independently subjected to transmission precoding or pre-DFT transformation to obtain the complex value symbols of the frequency domain mapping within each target block. The complex value symbols after transmission precoding or pre-DFT transformation corresponding to UE1 to UE4 can be obtained:

[0615] The complex-valued symbols in the first target block are: [XX1, YY1, ZZ1, WW1, XX2, YY2, ZZ2, WW2, XX3, YY3, ZZ3, WW3];

[0616] The complex-valued symbols in the second target block are: [XX4, YY4, ZZ4, WW4, XX5, YY5, ZZ5, WW5, XX6, YY6, ZZ6, WW6].

[0617] The illustrated process is shown in Figures 6a, 6b, 6c and 6d.

[0618] After the above OCC transmission scheme, the four UEs obtain the frequency domain signal mapped to the frequency domain resources on the two PRBs on the lth symbol as shown in FIG6e.

[0619] The above embodiments can solve the problems of when OCC can or cannot be used, and how to use OCC when UCI is multiplexed on PUSCH.
