[0002] In a mobile communication system, due to a large communication coverage area and a possible large number of simultaneously connected users, to improve system capacity and enhance the ability of uplink user multiplexing, the capacity of the uplink channel can be enhanced. In related technologies, the capacity of the uplink channel is enhanced by a user multiplexing scheme of block-wise spreading of an orthogonal cover code (OCC). However, the block-wise spreading scheme requires the frequency domain resources of multiple users to completely overlap, resulting in poor flexibility in scheduling the frequency domain resources of multiple user multiplexing.

[0051] For ease of understanding, some content related to the embodiments of this application is explained as follows:

[0052] 1. NTN WID

[0053] In the related art, the specific scope of the Non-Terrestrial Network (NTN) Work item description (WID) in the uplink capacity enhancement direction is as follows:

[0054] {

[0055] Uplink Capacity / Throughput Enhancement for FR1-NTN[RAN1,RAN2,RAN4];

[0056] Study then specify,if beneficial,DFT-s-OFDMPUSCH enhancements via Orthogonal Cover Codes(OCC)

[0057] Determine the achievable capacity improvement to be targetedtaking into account realistic impairments(e.g.Doppler,time variation,phasedistortion,etc);

[0058] Specify necessary signalling,if needed;

[0059] Update RF requirements accordingly,ifneeded;

[0060] Note:The study can consider orthogonal cover codes across OFDM symbols,across slots,and / or within an OFDM symbol).

[0061] Note:the study phase is targetedto be completed by RAN#104;

[0062] Notes for this objective

[0063] The enhancement is not targeting improvements / impacts of MU-MIMO capability;

[0064] The enhancement is not targeted to PUSCH DMRS;

[0065] No enhancement for initial access;

[0066] Enhancements to PRACH are not in scope.

[0067] This feature may be applicable for UEs operating in terrestrial networks based on a common design.

[0068] }

[0069] As can be seen from the above description, the enhancement of uplink capacity mainly considers using OCC to improve capacity in the data part of DFT-s-OFDM PUSCH, without enhancing the DMRS part.

[0070] 2. Block-wise spreading

[0071] In the existing protocol, in order to improve the multiplexing ability of User Equipment (UE, i.e., the terminal) and thus enhance the system capacity, a transmission method of block-wise spreading based on OCC (orthogonal cover code) is introduced in PUCCH transmission.

[0072] In TS38.211, the Block-wise spreading scheme is as follows:

[0073] For PUCCH format 3 with interlaced mapping and PUCCH format 4, block-wise spreading shall be applied according to

[0074]

[0075]

[0076]

[0077] where

[0078] - For PUCCH format 3 with interlaced mapping, if a single interlace is configured, 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);

[0079] - 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 (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);

[0080] 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 wn is given by Tables 6.3.2.6.3-1and 6.3.2.6.3-2 for where n is the index of the orthogonalsequence to use according to clause 9.2.1of[5,TS 38.213].The quantity is given by the higher-layer parameter occ-Length if provided,otherwise )。

[0081] When the orthogonal sequences w n (m) for PUCCH format 3 with interlaced mapping and PUCCH format 4 n when ) are as shown in the following table:

[0082] n <![CDATA[w n > 0 [+1 +1] 1 [+1 -1]

[0083] When the orthogonal sequences w n (m) for PUCCH format 3 with interlaced mapping and PUCCH format 4 n when ) are as shown in the following table:

[0084] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 -j -1 +j] 2 [+1 -1 +1 -1] 3 [+1 +j -1 -j]

[0085] For PUCCH format 3, transmission with block-wisespreading is only supported in the case of interlace mapping, and multiplexing for 1 / 2 / 4 users is only supported when single interlace is configured;

[0086] For PUCCH format 4, multiplexing for 2 / 4 users is supported and is configured by the higher-layer parameter occ-Length.

[0087] As can be seen from the above formula,

[0088] (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;

[0089] (2) As can be seen from , those continuous subcarriers satisfying in the frequency domain are multiplied by the same , that is, these continuous subcarriers can be understood as a block.

[0090] (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.

[0091] (4) The maximum number of multiplexed users is 4.

[0092] (5) Only users allocated the same RB can be multiplexed together.

[0093] In addition, regarding the principle of block-wise spreading, it can be obtained through the following process:

[0094] For 2-UE multiplexing, UE 0 and UE 1 are (To 2UE multiplexing, for UE 0 and UE 1 are):

[0095] S0 = a0, a1, …, a 59 , a0, a1, …, a 59 ;

[0096] And (and)

[0097] S1 = b0, b1, …, b 59 , -b0, -b1, …, -b 59 .

[0098] 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:

[0099] 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:

[0100]

[0101] 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),

[0102]

[0103] Obviously, when k is odd k X = 0.

[0104] 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),

[0105]

[0106] Therefore, in this case, when k is even k X = 0.

[0107] Based on the above analysis, we can conclude that the pre-DFT-OCC user multiplexing is equivalent to the comb-based user multiplexing.

[0108] 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.

[0109] As can be seen from the above principle introduction, for block-wise spreading, after different UEs are multiplied by different OCC sequences, and then using the characteristics of the FFT transform, different UEs occupy different REs when mapped in the frequency domain after the pre-DFT transform. For example, UE0 occupies odd REs and UE1 occupies even REs, thus achieving the effect of comb mapping and realizing multi-user multiplexing.

[0110] An example of the block-wise spreading scheme is as follows:

[0111] 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.

[0112] 3. Resource allocation in frequency domain for PUSCH

[0113] For the resource allocation in frequency domain for PUSCH, currently 3 types are supported: type 0 / type 1 / type 2. And the PUSCH supporting the DFT-s-OFDM waveform only supports the resource allocation in frequency domain of type 1 and type 2.

[0114] (1) Uplink resource allocation type 0: mainly the resource allocation in frequency domain based on RBG.

[0115] (2) Uplink resource allocation type 1: mainly the resource allocation in frequency domain of continuous non-interleaved VRBs, using the RIV coding method to indicate the starting RB and the number of RBs.

[0116] The uplink type 1 resource allocation field consists of a resource indication value (RIV) corresponding to the starting virtual resource block (RB start ) and a length in terms of continuously allocated resource blocks L RBs . The resource indication value is defined (An uplink type 1 resource allocation field consists of a resource indication value (RIV) corresponding to a starting virtual resource block (RB start ) and a length in terms of contiguously allocated resource blocks L RBs . The resource indication value is defined by):

[0117]

[0118]

[0119] else

[0120]

[0121] where L RBs ≥1 and shall not exceed (where L RBs ≥1 and shall not exceed ).

[0122] When the DCI size of DCI format 0_0 on the USS is determined by the size of the initial UL BWP but applied to another active BWP with size of if then K is defined as the maximum value in the set {1, 2, 4, 8}, and this set needs to satisfy otherwise K = 1. Then:

[0123] The uplink type 1 resource block assignment field includes a resource indication value (RIV) corresponding to the starting resource block and a length in terms of virtually contiguously allocated resource blocks (an uplink type 1 resource block assignment field consists of a resource indication value (RIV) corresponding to a starting resource block and a length in terms of virtually contiguously allocated resource blocks ).

[0124] The resource indication value is defined by:

[0125]

[0126]

[0127] else

[0128]

[0129] Among them, L' RBs = L RBs / K, RB' start = RB start / K, and L' RBs shall not exceed (where L' RBs = L RBs / K, RB' start = RB start / K and where L' RBs shall not exceed )。

[0130] When the uplink scheduling is carried by DCI format 0_2 or 0_3,

[0131] When receiving a scheduling grant in DCI format 0_2 or 0_3, the uplink type 1 resource allocation field consists of a resource indication value (RIV) corresponding to the starting resource block group RBGstart = 0, 1, …, NRBG-1 and a length in terms of resource block groups LRBGs = 1, ……, NRBG allocated in a virtual contiguous manner, where, if the UE is configured with the higher layer parameter resourceAllocationType1GranularityDCI-0-2 or resourceAllocationType1GranularityDCI-0-3, the resource block group is defined as in 6.1.2.2.1, where P is defined by resourceAllocationsType1GranularDCI-0-2 for DCI format 0_2 and resourceAllovationType1GRanularityDCI-0-3 for DCI format 0_3, otherwise P = 1.The resource indication value is defined as follows (When the scheduling grant is received with DCI format 0_2 or 0_3, an uplink type 1 resource allocation field consists of a resource indication value (RIV) corresponding to a starting resource block group RBGstart = 0, 1, …, NRBG - 1 and a length in terms of virtually contiguously allocated resource block groups LRBGs = 1, …, NRBG, where the resource block groups are defined as in 6.1.2.2.1 with P defined by resourceAllocationType1GranularityDCI - 0 - 2 for DCI format 0_2 and by resourceAllocationType1GranularityDCI - 0 - 3 for DCI format 0_3 if the UE is configured with higher layer parameter resourceAllocationType1GranularityDCI - 0 - 2 or resourceAllocationType1GranularityDCI - 0 - 3, and P = 1 otherwise. The resource indication value is defined by):

[0132]

[0133] RIV = N RBG (L RBGs - 1) + RBG start

[0134] else

[0135] RIV = N RBG (N RBG - L RBGs + 1) + (N RBG - 1 - RBG start )

[0136] wherein, L RBGs ≥1 and does not exceed N RBG -RBG start (where L RBGs ≥1 and shall not exceed N RBG -RBG start ).

[0137] (3) Uplink resource allocation type 2: mainly based on frequency-domain resource allocation in the interleaved mapping mode, this frequency-domain resource allocation information indicates to the UE a set of interlace indices up to M, and a set of RBs of up to consecutive RBs (for DCI 0_0 / 0_1), where the definitions of M and interlace indexing refer to TS 38.211 Clause 4.4.4.6.

[0138] Specifically, the frequency-domain resource allocation is as follows:

[0139] For μ = 0, the X = 6 MSBs in the resource block allocation information indicate to the UE a set of allocated interlace indices m0 + l, where the indication consists of a resource indication value (RIV). For 0 ≤ RIV < M(M + 1) / 2, l = 0, 1,..., L - 1, the resource indication value corresponds to the starting interlace index m0 and the number of contiguous interlace indices L (L ≥ 1). The resource indication value is defined by:

[0140]

[0141] RIV = M(L - 1) + m0

[0142] else

[0143] RIV = M(M - L + 1) + (M - 1 - m0)

[0144] For RIV ≥ M(M + 1) / 2, the resource indication value corresponds to the starting interlace index m0 and the set of values l according to Table 6.1.2.2.3-1. Table 6.1.2.2.3-1: m0 and l for RIV ≥ M(M + 1) / 2. Table 6.1.2.2.3-1 in the protocol is shown as follows:

[0145]

[0146] For μ = 1, the X = 5 MSBs of the resource block assignment information comprise a bitmap indicating the interlaces that are allocated to the scheduled UE. The bitmap is of size M bits with one bitmap bit per interlace such that each interlace is addressable, where M and interlace indexing is defined in Clause 4.4.4.6 in [4, TS 38.211]. The order of interlace bitmap is such that interlace 0 to interlace M-1 are mapped from MSB to LSB of the bitmap. An interlace is allocated to the UE if the corresponding bit value in the bitmap is 1; otherwise the interlace is not allocated to the UE.

[0147] For DCI 0_0 monitored in the search space of a particular UE and for DC 0_1 for both μ = 0 and μ = 1, the resource allocation field consists of a resource indication value (RIV RB-set ). For l = 0, 1, … L RBset -1, the resource indication value corresponds to the starting RB set index and the number of consecutive RB sets Resource Indication Value Definition (For DCI 0_0 monitored in a UE - specific search space and DC 0_1 for both μ = 0 and μ = 1, the the resource block assignment information indicate to a UE a set of contiguously allocated RB sets for PUSCH scheduled by DCI 0_0 monitored in a UE - specific search space, DCI 0_1 and Type 1 and Type2 configured grant. The resource allocation field consists of a resource indication value (RIV RB-set ). For l = 0, 1, … L RBset - 1 the resource indication value corresponds to the starting RB set index and the number of contiguous RB sets L RB-set . The resource indication value is defined by):

[0148]

[0149]

[0150] else

[0151]

[0152] where L RB-set ≥ 1 and shall not exceed

[0153] If transform precoding is enabled according to the procedure in Clause 6.1.3, the UE transmits the PUSCH on the PRBs with the lowest index among the PRBs indicated by the frequency - domain resource allocation information . is the maximum integer not greater than the number of RBs indicated by the frequency domain resource allocation information that satisfies the conditions in Clause 6.3.1.4 of [4, TS 38.211] (If transformprecoding is enabled according to the procedure in Clause 6.1.3, then the UE transmits PUSCH on the lowest-indexed PRBs amongst the PRBs indicated by the frequency domain resource assignment information. is the largestinteger not greater than the number of RBs indicated by the frequency domainresource assignment information that fulfills the conditions in Clause6.3.1.4of[4,TS 38.211]).

[0154] The information transmission method, device, and terminal provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0155] See also Figure 3 , Figure 3 This is a flow chart of an information transmission method provided by an embodiment of the present application. Figure 3 As shown, the information transmission method includes the following steps:

[0156] Step 101: A terminal performs uplink transmission based on an orthogonal cover code (OCC) sequence in at least one target block.

[0157] The OCC sequences corresponding to the at least one target block are the same.

[0158] It should be noted that 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.

[0159] Among them, the target block in the at least one target block is only a pseudonym, representing 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.

[0160] Among them, the uplink transmission may include Physical Uplink Control Channel (PUCCH) transmission, Physical Uplink Shared Channel (PUSCH) transmission, Narrowband Physical Uplink Shared Channel (NPUSCH) transmission, etc. This embodiment does not limit this.

[0161] In one implementation, the terminal may determine the information of the target block based on the first information;

[0162] The terminal performs uplink transmission within the target block based on the OCC sequence.

[0163] In one implementation, the first information may include at least one of the following: relevant information of the target block, OCC configuration information.

[0164] In one implementation, for the terminal to perform uplink transmission within at least one target block based on the OCC sequence, it may include multiplying the transmission symbols mapped within the target block by the OCC sequence, and then performing DFT transformation (such as pre-DFT transformation or transmission precoding) to obtain the transmission symbols before frequency domain mapping; and performing frequency domain mapping through the transmission symbols before frequency domain mapping to achieve uplink transmission.

[0165] It should be noted that the target block can be multiplexed by multiple users, and the number of multiplexed users of the target block can be greater than 4. Multiple terminals can perform uplink transmission based on the OCC sequence through the same target block.

[0166] The embodiment of the present application proposes an uplink transmission method based on OCC-based multi-user multiplexing, which performs multi-user multiplexing uplink transmission within the target block based on the OCC sequence. Since the OCC sequence used within the same target block is the same, when performing multi-user multiplexing, it only needs to ensure that the overlapping frequency domain resources among multiple users are within the same target block, and it does not require the frequency domain resources of multiple users to completely overlap, thus solving the problem of limited flexibility in scheduling frequency domain resources for multi-user multiplexing.

[0167] In the NTN scenario, due to the large coverage area and the potentially large number of simultaneously connected users, in order to improve system capacity and enhance the ability of uplink user multiplexing, it is necessary to enhance the capacity of the uplink channel. Since in the NTN scenario, only single-layer transmission is supported and the DMRS ports already support multi-port multiplexing, therefore, it is necessary to enhance the capacity of the data part of the uplink channel. In the related art, the user multiplexing scheme based on OCC's block-wise spreading supports a limited number of multiplexed users and has poor flexibility in frequency-domain scheduling. The multi-user multiplexing scheme based on OCC in the embodiments of the present application can solve the above limitations.

[0168] In the related art, for a block-wise spreading transmission mode similar to PUCCH format 4, it multiplies with the OCC sequence in units of a "block" and utilizes the characteristics of the Discrete Fourier Transform (DFT) to achieve the effect of comb mapping among multiple users in the frequency domain. It supports a maximum of 4 users for multiplexing, and only users scheduling the same resource block (RB) can be multiplexed together. Therefore, the multiplexing scheme in the related art has problems of limited number of multiplexed users and limited flexibility in frequency-domain scheduling.

[0169] The embodiments of the present application propose an uplink transmission method based on OCC multi-user multiplexing to solve the problem of limited flexibility in frequency-domain scheduling for multi-user multiplexing. Through the embodiments of the present application, for the same transmission of the same terminal in different target blocks, the OCC sequences used are the same. Therefore, when performing multi-user multiplexing, it only needs to ensure that the overlapping frequency-domain resources among multiple users are within the same target block, and it does not require the frequency-domain resources of multiple users to completely overlap, thus solving the problem of limited flexibility in frequency-domain resource scheduling for multi-user multiplexing.

[0170] In one implementation, the target block in the embodiments of the present application can be understood as a sub-block of the "block" in the block-wise spreading scheme of PUCCH format 4.

[0171] It should be noted that the application of the embodiments of the present application is not limited to the NTN scenario and can also be applicable to scenarios such as the TN scenario. The embodiments of the present application are not only applicable to the NR system but also applicable to the LTE NB-IOT system or the IoT NTN system.

[0172] In an embodiment of the present application, the terminal performs uplink transmission based on an orthogonal cover code (OCC) sequence within at least one target block; wherein, the OCC sequences corresponding to the at least one target block are the same; in this way, since the OCC sequences used by the terminal for uplink transmission within at least one target block are the same, when supporting multi-user multiplexing, it is not required that the frequency-domain resources of multiple users completely overlap, and the flexibility of multi-user multiplexing frequency-domain resource scheduling can be improved.

[0173] Optionally, before the terminal performs uplink transmission based on the OCC sequence within at least one target block, the method further includes:

[0174] The terminal determines the at least one target block based on first information;

[0175] Wherein, the first information includes at least one of the following:

[0176] Relevant information of the target block; OCC configuration information.

[0177] In this embodiment, the terminal determines the at least one target block based on the first information, and the terminal performs uplink transmission based on the orthogonal cover code (OCC) sequence within the at least one target block, which can improve the flexibility of multi-user multiplexing frequency-domain resource scheduling.

[0178] Optionally, the relevant information of the target block includes at least one of the following:

[0179] 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 enabling information of the target block;

[0180] 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.

[0181] Wherein, the enabling information of the target block can represent whether the target block is enabled.

[0182] In one embodiment, the relevant information of the target block includes at least the size of the target block, the number of target blocks, the bitmap of the target block, the position of the target block, the number of the target block, or the enabling information of the target block.

[0183] 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., the terminal) can be multiplexed, and each target block performs an independent DFT transform (such as transmission precoding or pre-DFT transform).

[0184] In addition, the size of the target block can be in units of resource elements (REs), subcarriers, RBs, or resource element groups (REGs). For example, for the Internet of Things (IoT), scheduling can be performed in single tone or multi-tones, so 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, so the size of the target block can be greater than or equal to 1 RB.

[0185] 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 based on the frequency domain resources and the OCC length.

[0186] 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 the target block * Number of target blocks = Frequency domain resources allocated for uplink transmission (number of RBs, REs, or subcarriers) or transmission bandwidth (the number can be represented by the number of REs or subcarriers, and the same granularity is maintained among several variables).

[0187] In addition, based on the size of the target block and the frequency domain resources allocated in combination with the FDRA, the number of target blocks can also be determined.

[0188] 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.

[0189] 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 it does not enable, it means that target uplink transmission is not performed, and uplink transmission is carried out according to the normal process, or whether to enable target uplink transmission 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.

[0190] The position of the target block is determined based on the frequency domain resources allocated by the FDRA, as well as the size / number of the target block.

[0191] Optionally, the OCC configuration information is used to configure at least one of the following:

[0192] OCC base sequence information; OCC index information; OCC length; OCC multiplexing factor.

[0193] Among them, the OCC multiplexing factor characterizes the number of users that can be multiplexed within the target block. For example, it indicates how many users can be multiplexed within the target block.

[0194] Among them, the OCC base sequence information may include an OCC base sequence set, an OCC base sequence table, an OCC base sequence, etc., which are used to determine the OCC base sequence.

[0195] Among them, the OCC index information may include an OCC index, an OCC index set, an OCC index table, etc., which are used to determine the OCC index.

[0196] In one implementation, the OCC configuration information may include at least one of the following: OCC base sequence set / OCC base sequence, OCC index / OCC index set, OCC length, OCC multiplexing factor.

[0197] Among them, 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.

[0198] 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 on the first stream.

[0199] Among them, different target blocks may indicate different OCC indexes.

[0200] Among them, the OCC length is the length of an OCC base sequence and can be determined by the maximum number of multiplexed users supported in the target block.

[0201] Optionally, before the terminal determines the at least one target block based on the first information, the method further includes:

[0202] The terminal receives the first information sent by the network-side device.

[0203] In this implementation, the terminal receives the first information sent by the network-side device, determines the at least one target block based on the first information, and the terminal performs uplink transmission based on the orthogonal cover code (OCC) sequence within the at least one target block, which can improve the flexibility of multi-user multiplexing frequency-domain resource scheduling.

[0204] Optionally, the OCC sequence is obtained through a first operation based on the OCC base sequence and the size of the target block.

[0205] In one implementation, the OCC sequence may be obtained through a first operation of the OCC base sequence corresponding to the size of the target block.

[0206] Among them, the OCC base sequence can be the OCC base sequence carried by the first information or the OCC sequence in the existing protocol, such as OCC2 or OCC4.

[0207] OCC2 is shown in the following table:

[0208] n <![CDATA[w n > 0 [+1 +1] 1 [+1 -1]

[0209] OCC4 is shown in the following table:

[0210] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 -j -1 +j] 2 [+1 -1 +1 -1] 3 [+1 +j -1 -j]

[0211] It should be noted that which OCC base sequence to use specifically can be determined based on the OCC length and the OCC index. The OCC length is related to the number of multiplexed users, the OCC length can be indicated by the network, and the OCC index can be indicated by the network.

[0212] For example, if the OCC length is 2 and the OCC index configured for UE1 is 0, it means using the first sequence in OCC2; if the OCC index configured for UE2 is 1, it means using the second sequence in OCC2.

[0213] Among them, the first operation can 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.

[0214] It should be noted that the target block size can be divided by the OCC base sequence length to obtain the number of times each element in the OCC sequence needs to be repeated. For example: the target block size is 2RB = 24REs, and the OCC base sequence is: [1 1j -1 -1j], then the OCC sequence used within the target block obtained after applying the first operation is: [1 1 1 1 1 1 1j 1j 1j 1j 1j 1j -1 -1 -1 -1 -1 -1 -1j -1j -1j -1j -1j -1j].

[0215] Optionally, the first operation includes: repeating the elements in the OCC base sequence a target number of times so that the sequence length of the OCC sequence matches the size of the target block.

[0216] Among them, repeating the elements in the OCC base sequence a target number of times so that the sequence length of the OCC sequence matches the size of the target block may mean repeating the elements in the OCC base sequence a target number of times so that the sequence length of the OCC sequence is the same as the size of the target block.

[0217] In one implementation, the first operation may be to repeat each element in the OCC base sequence by a corresponding length so that the length of the resulting OCC sequence is the same as the size of the target block. For example, if the OCC base sequence is: [+1 -1 +1 -1], and the target block size is 12, the OCC sequence obtained after the first operation is: [+1 +1 +1 -1 -1 -1 +1 +1 +1 -1 -1 -1].

[0218] Optionally, the terminal performs uplink transmission based on the OCC sequence within at least one target block, including:

[0219] The terminal multiplies the transmission symbols mapped within each target block in the at least one target block by the OCC sequence to obtain first transmission symbols corresponding to each target block;

[0220] The terminal performs discrete Fourier transform (DFT) processing on the first transmission symbols corresponding to each target block to obtain second transmission symbols corresponding to each target block;

[0221] The terminal performs uplink transmission based on the second transmission symbols corresponding to each target block.

[0222] Wherein, 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 a transmission precoding transform. The DFT processing may also be described as DFT transform processing.

[0223] Wherein, the transmission symbol may refer to a complex-valued constellation point symbol after modulation. All physical layer processes from after modulation to before resource mapping are in the form of transmission symbols (or described as symbol-level processing, or non-bit-level processing).

[0224] In addition, the terminal multiplying the transmission symbols mapped within each target block in the at least one target block by the OCC sequence may include: the terminal multiplying the transmission symbols by the OCC sequence corresponding to each target block in the at least one target block.

[0225] In one implementation, performing uplink transmission based on the OCC sequence within the target block may be to multiply the transmission symbols mapped within the target block by the OCC sequence and then perform DFT transform (such as Pre-DFT transform or transmission precoding) to obtain the transmission symbols before frequency domain mapping.

[0226] For example, to give a formula similar to format 4,

[0227] Assume 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, y(0), …, y(M symb L-1) represents the replicated modulation symbols before the DFT transform.

[0228] In one implementation, for the target block #i on symbol #l, the transmitted symbol mapped within the target block is multiplied by the OCC sequence, corresponding to the following formula:

[0229]

[0230] Where:

[0231] i = 0, 1, …, M block -1;

[0232]

[0233]

[0234]

[0235] l = 0, 1, …, (M symb L / M sc )-1;

[0236] M sc represents the number of subcarriers or REs corresponding to the frequency-domain resources allocated for the uplink transmission;

[0237] M symb represents the number of replicated modulation symbols that can be transmitted in the uplink transmission;

[0238] M block represents the number of target blocks (within the uplink transmission allocated bandwidth / frequency-domain resources);

[0239] represents the size of the target block, in units of RE or number of subcarriers;

[0240] L represents the OCC length or multiplexing factor;

[0241] represents the number of complex-valued modulation symbols transmitted within one target block;

[0242] n is determined by the OCC index, w n represents the OCC base sequence;

[0243] Satisfies:

[0244] In one implementation, for the entire uplink transmission (including all the scheduled time-domain symbols, i.e., l = 0, 1, …, (M symb L / Msc )-1):

[0245]

[0246] Wherein:

[0247] k = 0, 1, …, M sc -1; l = 0, 1, …, (m symb L / M sc )-1;

[0248] M sc represents the number of subcarriers or REs corresponding to the frequency-domain resources allocated for uplink transmission;

[0249] M symb represents the number of replicated modulation symbols that can be transmitted in uplink transmission;

[0250] M block represents the number of target blocks (within the bandwidth or frequency-domain resources allocated for uplink transmission);

[0251] represents the size of the target block, in units of RE or number of subcarriers;

[0252] L represents the OCC length or the multiplexing factor;

[0253] represents the number of complex-valued modulation symbols transmitted within one target block;

[0254] n is determined by the OCC index, w n represents the OCC base sequence;

[0255] Satisfy:

[0256] 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.

[0257] In this embodiment, the terminal multiplies the transmission symbols mapped within 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; 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; the terminal performs uplink transmission based on the second transmission symbol corresponding to each target block. Thus, uplink transmission based on the OCC sequence can be achieved within at least one target block.

[0258] Optionally, the calculation method of the second transmission symbol y is:

[0259]

[0260] Wherein:

[0261] i = 0, 1, …, M block -1;

[0262]

[0263]

[0264]

[0265] l = 0, 1, …, (M symb L / M sc ) - 1;

[0266] M sc represents the number of sub - carriers or REs corresponding to the frequency - domain resources allocated for uplink transmission;

[0267] M symb represents the number of replicated modulation symbols that can be transmitted in uplink transmission;

[0268] M block represents the number of target blocks;

[0269] represents the size of the target block;

[0270] L represents the OCC length or the multiplexing factor;

[0271] represents the number of complex - valued modulation symbols transmitted within one target block;

[0272] n is determined by the OCC index, w n represents the OCC base sequence.

[0273] Satisfy:

[0274] Wherein, the second transmission symbol y can be the second transmission symbol y on the time - domain symbol #l of the uplink transmission.

[0275] The signal calculated in this embodiment is on the symbols allocated for the entire uplink transmission. The value of l starts from 0, and 0 corresponds to the first symbol of the allocated time - domain symbols. d is the transmission symbol before target - block processing, that is, the transmission symbol one step before obtaining the first transmission symbol.

[0276] Optionally, the calculation method of the second transmission symbol y is:

[0277]

[0278] Wherein:

[0279] k = 0, 1, …, Msc -1;

[0280] l=0,1,…,(M symb L / M sc )-1;

[0281] M sc Indicates the number of subcarriers or REs corresponding to the frequency domain resources allocated for uplink transmission;

[0282] M symb Indicates the number of replica modulation symbols that can be transmitted for uplink transmission;

[0283] M block Indicates the number of target blocks;

[0284] Indicates the size of the target block;

[0285] L represents the OCC length or multiplexing factor;

[0286] Indicates the number of complex-valued modulation symbols transmitted within a target block;

[0287] n is determined by the OCC index, w n Represents an OCC base sequence.

[0288] satisfy:

[0289] This implementation manner calculates the transmission symbol mapped to the frequency domain resource on symbol 1.

[0290] Optionally, the size of the target block is determined based on at least one of the following:

[0291] Instructions for information instructions; or

[0292] In the case where the uplink resource allocation type is the first type: the target block is less than or equal to the length of the consecutively allocated resource blocks; or the size of the target block is the maximum value in a first set, the first set being determined based on the size of the initial uplink (UL) bandwidth part (BWP) and the size of the activated UL BWP; or the size of the target block is the calibrated resource block group (RBG) size; or

[0293] In the case where the uplink resource allocation type is the second type: the size of the target block is a continuous weaving index length; or the size of the target block is the number of continuous resource block (RB) sets.

[0294] Among them, the first type may be uplink resource allocation type 1; the second type may be uplink resource allocation type 2.

[0295] In one implementation, the size of the target block may be determined by at least one of the following methods:

[0296] (1) Newly defined parameter indication (i.e., indication information indication);

[0297] (2) Under uplink resource allocation type 1, the size of the target block may be determined by at least one of the following methods (method a or method b or method c):

[0298] a) Target block size <= L RBs ;

[0299] b) Target block size = K, when the DCI size of DCI format 0_0 on the USS is determined by the initial UL BWP with size but applied to another active BWP with a size of If then K is defined as the maximum value in the set {1, 2, 4, 8}, and this set needs to satisfy

[0300] c) Target block size = Nominal RBG size P, when the uplink scheduling is carried by DCI format 0_2 or 0_3, P is defined by resourceAllocationType1GranularityDCI-0-2 for DCI format 0_2 and by resourceAllovationType1GRanularityDCI-0-3 for DCI format 0_3 (P defined by resourceAllocationType1GranularityDCI-0-2 for DCI format ǒ_2 and by resourceAllocationType1GranularityDCI-0-3 for DCI format 0_3);

[0301] (3) Under uplink resource allocation type 2, the size of the target block may be determined by at least one of the following methods (method a or method b):

[0302] a) For μ = 0, the X = 6 MSBs, the target block size = L, where L is the length of consecutive interlace indices (L ≥ 1);

[0303] b) For the uplink transmission scheduled by DCI 0_0 on the USS, and the uplink transmission scheduled by DC 0_1 for both μ = 0 and μ = 1 (DC 0_1 for both μ = 0 and μ = 1), the target block size = L RB-set , L RB-set is the number of consecutive RB sets.

[0304] Optionally, the first information is used to indicate the frequency-domain resources allocated for the uplink transmission, and the terminal determines the at least one target block based on the first information, including:

[0305] The terminal determines the number of the at least one target block configured for the terminal based on the frequency-domain resources allocated for the uplink transmission.

[0306] In one implementation, the number of the target block can be related to the division of the frequency-domain resources allocated for the uplink transmission, and the number of the target block is defined relative to the lowest RB index with respect to CRB0 or point A or CORESET#0. CRB refers to the Common Resource Block. CORESET refers to the Control Resource Set.

[0307] For example: CRB#0 and CRB#1 are divided into target block #0, CRB#2 and CRB#3 are divided into target block #1. If the frequency-domain resources of UE1 occupy CRB#0 and CRB#1, then the number of the target block configured for UE1 is #0; if the frequency-domain resources of UE1 occupy CRB#1 and CRB#2, then the numbers of the target blocks configured for UE1 are #0 and #1.

[0308] It should be noted that the number of the target block can be calculated based on the CRB or RB index, or the number of the target block can be associated with the CRB or RB index.

[0309] In one implementation, a terminal can be indicated or configured with one or more target block numbers.

[0310] For example, CRB#0 and CRB#1 are divided into target block #0, CRB#2 and CRB#3 are divided into target block #1. If the frequency-domain resources of UE1 occupy CRB#1 and CRB#2, the frequency-domain resources of UE2 occupy CRB#0 and CRB#1, and the frequency-domain resources of UE3 occupy CRB#2 and CRB#3, then the target block numbers configured for UE1 are #0 and #1, the target block number configured for UE2 is #0, and the target block numbers configured for UE3 are #1 respectively. In this case, it can be known that UE1 and UE2 are multiplexed on target block number #0, while UE1 and UE3 are multiplexed on target block number #1.

[0311] In this embodiment, the terminal determines the numbers of the at least one target block configured for the terminal based on the frequency-domain resources allocated for the uplink transmission, so as to be able to determine the at least one target block, and perform uplink transmission within the at least one target block based on the orthogonal cover code OCC sequence, which can improve the flexibility of multi-user multiplexing frequency-domain resource scheduling.

[0312] Optionally, the numbers of the at least one target block are determined based on the common resource block or the common reference point or the RB index of the control resource set in the frequency-domain resources allocated for the uplink transmission.

[0313] Among them, the numbers of the at least one target block can be determined based on the minimum RBindex of CRB0 or point A or CORESET#0.

[0314] For example: CRB#0 and CRB#1 are divided into target block #0, CRB#2 and CRB#3 are divided into target block #1. If the frequency-domain resources of UE1 occupy CRB#0 and CRB#1, then the target block number configured for UE1 is #0; if the frequency-domain resources of UE1 occupy CRB#1 and CRB#2, then the target block numbers configured for UE1 are #0 and #1.

[0315] Optionally, the OCC index information corresponding to the OCC sequence is determined based on at least one of the following:

[0316] The numbers of the at least one target block; the index of the frequency-domain resources of the uplink transmission; the terminal identifier.

[0317] In one embodiment, the OCC index can be determined by the number of the target block, or by the index of the frequency-domain resources of the uplink transmission, or by the UE ID.

[0318] For example: (the number of the target block + UE ID) mod OCC length = OCC index; or

[0319] (PRB number + UE ID) mod OCC length = OCC index; or

[0320] (CRB number + UE ID) mod OCC length = OCC index.

[0321] Optionally, the at least one target block is used for uplink transmission by one of the terminals; or, the at least one target block is used for uplink transmission by a terminal group including the terminal; or, the at least one target block is used for uplink transmission by multiple terminals.

[0322] In one implementation, the target block can be used by one UE, or can be used by a UE group or shared by multiple UEs.

[0323] For example, when used by one UE, the transmission replica modulation symbols before multiplying the OCC sequence in the target block only contain the transmission symbols of this UE; while when used by a UE group, the transmission replica modulation symbols before multiplying the OCC sequence may contain the transmission symbols of multiple UEs or all UEs within the same UE group.

[0324] Optionally, the first information is used to indicate at least one terminal group, each terminal group in the at least one terminal group corresponds to a target block, and the terminal is a terminal in the at least one terminal group.

[0325] In one implementation, one terminal can be indicated or configured with one or more UE group numbers.

[0326] Exemplarily, UE1 and UE2 are multiplexed on RB#0, and UE1 and UE3 are multiplexed on RB#1. Assuming RB#0 corresponds to one UE group and RB#1 corresponds to another UE group, then for UE1, it may be necessary to configure two UE group IDs.

[0327] In one implementation, a UE group number can have a corresponding relationship with a target block number. For example, a UE group number can correspond one-to-one with a target block number; or a target block number can correspond to multiple UE groups.

[0328] In this case, one UE group can only be within one target block, and one target block can contain multiple UE groups.

[0329] For example, CRB#0 and CRB#1 are divided into target block #0, CRB#2 and CRB#3 are divided into target block #1. If UE1 and UE2 are configured as UE group #1, and UE3 and UE4 are configured as UE group #2, and if UE group #1 corresponds to target block #0, then the frequency domain resources of UE1 occupy CRB#0 or CRB#1, and the frequency domain resources of UE2 occupy CRB#0 or CRB#1.

[0330] From another perspective, CRB#0 and CRB#1 are divided into target block #0, CRB#2 and CRB#3 are divided into target block #1. The frequency domain resources of UE1 occupy CRB#0 or CRB#1, and the frequency domain resources of UE2 occupy CRB#0 or CRB#1, and UE group #1 corresponds to target block #0. It should be understood that the user groups to which UE1 and UE2 can be configured are UE group #1. Similarly, UE group #2 also corresponds to target block #0, then the frequency domain resources of UE3 and UE4 in UE group #2 occupy CRB#0 or CRB#1.

[0331] Optionally, the first information is configured through high-layer parameters of the network-side device, or carried by downlink control information (DCI) sent by the network-side device, or carried by a medium access control (MAC) control element (CE) sent by the network-side device.

[0332] In one implementation, the first information can be configured through high-layer parameters (such as configured through RRC), or carried by DCI, or carried by MAC CE.

[0333] For example:

[0334] Configure the first information in high-layer parameter configuration related to user multiplexing or in configured grant (CG) configuration related to uplink transmission;

[0335] Or, carry the first information in the scheduling DCI corresponding to uplink transmission, such as adding a new OCC indication field, or adding a target block indication field, or a multi-user multiplexing indication field; or repurpose other indication fields in the existing DCI.

[0336] Optionally, before the terminal performs uplink transmission based on the OCC sequence in at least one target block, the method further includes:

[0337] The terminal sends terminal capability information to the network-side device;

[0338] Among them, the terminal capability information is used to indicate at least one of the following:

[0339] Whether the terminal supports the target uplink transmission;

[0340] The maximum target block size that the terminal supports for the target uplink transmission;

[0341] The maximum number of target blocks that the terminal supports for the target uplink transmission;

[0342] The maximum OCC length that the terminal supports for the target uplink transmission;

[0343] Among them, the target uplink transmission is an uplink transmission based on the OCC sequence within the at least one target block.

[0344] In one implementation, the target uplink transmission can also be described as sub-block OCC transmission. Before the terminal receives the first information for OCC-based uplink transmission, the terminal reports the terminal capability information to the network-side device. The terminal capability information includes at least one of the following:

[0345] Whether the UE supports the target uplink transmission;

[0346] The maximum target block size that the UE supports for the target uplink transmission;

[0347] The maximum number of target blocks that the UE supports for the target uplink transmission;

[0348] The maximum OCC length that the UE supports for the target uplink transmission.

[0349] The above different terminal capability information may correspond to different UE capability levels, and the network-side device can perform scheduling of the corresponding target uplink transmission according to different UE capability levels.

[0350] In this implementation, the terminal sends the terminal capability information to the network-side device, so that the network side can configure the first information according to the capability information of the terminal, enabling the terminal to determine the at least one target block based on the first information, and the terminal performs uplink transmission based on the orthogonal cover code OCC sequence within the at least one target block, which can improve the flexibility of multi-user multiplexing frequency-domain resource scheduling.

[0351] The embodiment of the present application further provides an information transmission method. The information transmission method includes the following steps:

[0352] The network-side device sends the first information to the terminal;

[0353] Among them, the first information includes at least one of the following:

[0354] The relevant information of the target block; OCC configuration information.

[0355] Optionally, the method further includes:

[0356] The network-side device receives the terminal capability information sent by the terminal;

[0357] Wherein, the terminal capability information is used to indicate at least one of the following:

[0358] Whether the terminal supports target uplink transmission;

[0359] The maximum target block size that the terminal supports for target uplink transmission;

[0360] The maximum number of target blocks that the terminal supports for target uplink transmission;

[0361] The maximum OCC length that the terminal supports for target uplink transmission;

[0362] Wherein, the target uplink transmission is an uplink transmission based on an OCC sequence within the at least one target block.

[0363] It should be noted that, as the implementation manner of the network-side device corresponding to the Figure 3 embodiment shown, the specific implementation manner can refer to the relevant description of the Figure 3 embodiment shown. To avoid repeated description, this embodiment will not be elaborated herein.

[0364] The following uses several specific embodiments to illustrate the information transmission method provided by the embodiments of the present application:

[0365] In the following embodiments, the imaginary unit in the OCC base sequence or the OCC sequence is represented by i, and i can also be replaced by j.

[0366] Embodiment 1:

[0367] 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:

[0368] If the first information indicates that the size of the target block is 1 RB = 12 REs = 12 SCs, then: on these 2 PRBs, they are divided into 2 target blocks, the first target block occupies the first PRB, and the second target block occupies the second PRB;

[0369] 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:

[0370] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 +i -1 -i] 2 [+1 -1 +1 -1] 3 [+1 -i -1 +i]

[0371] UE1 is instructed that the OCC index = 0, that is, the OCC base sequence [+1 +1 +1 +1] is used;

[0372] UE2 is instructed that the OCC index = 1, that is, the OCC base sequence [+1 +i -1 -i] is used;

[0373] UE3 is instructed that the OCC index = 2, that is, the OCC base sequence [+1 -1 +1 -1] is used;

[0374] UE4 is instructed that the OCC index = 3, that is, the OCC base sequence [+1 -i -1 +i] is used.

[0375] Furthermore, the OCC sequences used by the 4 users in the target block are determined as:

[0376] UE1 uses the OCC sequence [+1+1+1+1+1+1+1+1+1+1+1+1];

[0377] UE2 uses the OCC sequence [+1+1+1+i+i+i-1-1-1-i-i-i];

[0378] UE3 uses the OCC sequence [+1+1+1-1-1-1+1+1+1-1-1-1];

[0379] UE4 uses the OCC sequence [+1+1+1-i-i-i-1-1-1+i+i+i].

[0380] Correspondingly,

[0381] 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;

[0382] 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;

[0383] 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;

[0384] 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.

[0385] Then, after each target block independently undergoes DFT transformation (such as transmission precoding or pre-DFT transformation), complex-valued symbols mapped in the frequency domain within each target block are obtained. The complex-valued symbols after DFT transformation corresponding to UE1 to UE4 can be obtained as follows:

[0386] The complex-valued symbols within the first target block are respectively: [XX1, YY1, ZZ1, WW1, XX2, YY2, ZZ2, WW2, XX3, YY3, ZZ3, WW3];

[0387] The complex-valued symbols within the second target block are respectively: [XX4, YY4, ZZ4, WW4, XX5, YY5, ZZ5, WW5, XX6, YY6, ZZ6, WW6].

[0388] The illustrated process is as Figure 4a 、 Figure 4b 、 Figure 4c and Figure 4d shown.

[0389] After these 4 UEs go through the above OCC transmission scheme, the frequency-domain signals mapped to the frequency-domain resources on these 2 PRBs at the l-th symbol are as Figure 4e shown.

[0390] As a comparison, it can be seen that under the same parameter configuration, the frequency-domain signals mapped to the frequency-domain resources by using the block-wise spreading method in the related technology are as Figure 5a 、 Figure 5b 、 Figure 5c and Figure 5d shown. Finally, after these 4 UEs go through block-wise spreading, the frequency-domain signals mapped to the frequency-domain resources on these 2 PRBs at the l-th symbol are as Figure 5e shown.

[0391] It can be seen through comparison that: [XX1, XX2, XX3] is only related to [x1, x2, x3] because they belong to the same target block, while for [X1, X2, X3], it is related to [x1, x2, x3, x4, x5, x6].

[0392] Embodiment 2:

[0393] In some embodiments, the first information includes the relevant information of the target block. The relevant information of the target block includes at least one of the following: the size of the target block, the number of target blocks, the bitmap of the target block (used to determine whether to enable the application of the OCC sequence within a certain target block), the position of the target block, and the number of the target block.

[0394] In some embodiments, the relevant information of the target block includes the size of the target block. If the target block size is indicated as 2RB, the frequency domain resources for uplink transmission are 10 PRBs from PRB#0 to PRB#9, which can be divided into one target block per 2RB. For example, PRB#0 and PRB#1 belong to the same target block, PRB#2 and PRB#3 belong to another target block, and so on.

[0395] In some embodiments, the relevant information of the target block includes the number of target blocks. If the number of target blocks is indicated as 5, and the frequency domain resources for uplink transmission are 10 PRBs from PRB#0 to PRB#9, then it can be determined that: 10 / 5=2RB, that is, every 2 PRBs are divided into a target block, for example, PRB#0 and PRB#1 belong to the same target block, PRB#2 and PRB#3 belong to another target block, and so on.

[0396] Example 3:

[0397] This embodiment illustrates the flexible multiplexing of UEs with the same OCC length on different RBs.

[0398] Assume that UE1, UE2, and UE3 are flexibly multiplexed on RB#0 and RB#1 as follows:

[0399] UE1 performs target uplink transmission on RB#0 and RB#1. The target uplink transmission is uplink transmission based on the OCC sequence within at least one target block. The target block size is 1RB = 12REs = 12SCs. Therefore, the two PRBs are divided into two target blocks. The first target block occupies RB#0, and the second target block occupies RB#1.

[0400] UE2 performs target uplink transmission on RB#0. The target block size is 1RB = 12REs = 12SCs, so the first target block occupies RB#0.

[0401] UE3 performs target uplink transmission on RB#1, and the target block size is 1RB=12REs=12SCs, which corresponds to RB#1 occupied by the second target block.

[0402] Taking the operation of the frequency domain signal on the lth symbol as an example, the operation of the frequency domain signal on the lth symbol is as follows:

[0403] For these three UEs, the number of multiplexed users indicated by the network side is 4, so the OCC length is configured as 4. Therefore, an OCC base sequence with a length of 4 is selected, for example:

[0404] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 +i -1 -i] 2 [+1 -1 +1 -1] 3 [+1 -i -1 +i]

[0405] UE1 is instructed that OCC index = 0, that is, the OCC base sequence [+1 +1 +1 +1] is used;

[0406] UE2 is instructed that OCC index = 1, that is, the OCC base sequence [+1 +i -1 -i] is used;

[0407] UE3 is instructed that OCC index = 2, that is, the OCC base sequence [+1 -1 +1 -1] is used.

[0408] Furthermore, the OCC sequences used by these 3 users in their respective target blocks are determined as:

[0409] UE1 uses the OCC sequence [+1+1+1+1+1+1+1+1+1+1+1+1];

[0410] UE2 uses the OCC sequence [+1+1+1+i+i+i-1-1-1-i-i-i];

[0411] UE3 uses the OCC sequence [+1+1+1-1-1-1+1+1+1-1-1-1].

[0412] Correspondingly,

[0413] 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;

[0414] The complex-valued modulation symbol transmitted by UE2 in the first target block is [y1, y2, y3];

[0415] The complex-valued modulation symbol transmitted by UE3 in the second target block is [z1, z2, z3].

[0416] Then, after each target block independently undergoes DFT transformation (such as 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 DFT transformation corresponding to UE1 to UE3 are as follows:

[0417] The complex-valued symbols in the first target block are respectively: [XX1, YY1, 0, 0, XX2, YY2, 0, 0, XX3, YY3, 0, 0];

[0418] The complex-valued symbols in the second target block are respectively: [XX4, 0, ZZ1, 0, XX5, 0, ZZ2, 0, XX6, 0, ZZ3, 0].

[0419] The illustrated process is as Figure 6a 、 Figure 6b 、 Figure 6c and Figure 6dAs shown in the figure.

[0420] Embodiment 4:

[0421] This embodiment illustrates the flexible multiplexing between UEs with different OCC lengths.

[0422] Assume that UE1 and UE2 perform flexible multiplexing on RB#0 and RB#1 as follows:

[0423] UE1 performs target uplink transmission on RB#0 and RB#1. The target uplink transmission is uplink transmission based on the OCC sequence within at least one target block. 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 RB#0, and the second target block occupies RB#1;

[0424] UE2 performs target uplink transmission on RB#0. The size of the target block is 1RB = 12REs = 12SCs. Then it corresponds to RB#0 occupied by the first target block;

[0425] 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:

[0426] For UE1, the OCC length configured by the network side is 4. Therefore, an OCC base sequence with a length of 4 is selected. For example:

[0427] n <![CDATA[w n > 0 [+1 +1 +1 +1] 1 [+1 +i -1 -i] 2 [+1 -1 +1 -1] 3 [+1 -i -1 +i]

[0428] UE1 is instructed that OCC index = 0, that is, the OCC base sequence [+1 +1 +1 +1] is used.

[0429] For UE2, the OCC length configured by the network side is 2. Therefore, an OCC base sequence with a length of 2 is selected. For example:

[0430] n <![CDATA[w n > 0 [+1 +1] 1 [+1 -1]

[0431] UE2 is instructed that OCC index = 1, that is, the OCC base sequence [+1 -1] is used.

[0432] Furthermore, the OCC sequences used by these 2 users within their respective corresponding target blocks are determined as:

[0433] UE1 uses the OCC sequence [+1+1+1+1+1+1+1+1+1+1+1+1];

[0434] UE2 uses the OCC sequence [+1+1+1+1+1+1-1-1-1-1-1-1].

[0435] Correspondingly,

[0436] 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;

[0437] The complex-valued modulation symbols transmitted by UE2 within the first target block are [y1, y2, y3].

[0438] Then, after each target block independently undergoes a DFT transformation (such as 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 DFT transformation corresponding to UE1 to UE2 are as follows:

[0439] The complex-valued symbols within the first target block are respectively: [XX1, YY1, 0, YY2, XX2, YY3, 0, YY4, XX3, YY5, 0, YY6];

[0440] The complex-valued symbols within the second target block are respectively: [XX4, 0, 0, 0, XX5, 0, 0, 0, XX6, 0, 0, 0].
