The embodiments of the present application include at least part of the following contents.

[0050] 1. RU (Resource Unit, resource unit)

[0051] RU is used to describe the mapping of NPUSCH (Narrowband Physical Uplink Shared Channel, narrowband physical uplink shared channel) to RE (Resource Element, resource element). One RU is defined as SC-FDMA (Single-Carrier Frequency-Division Multiple Access, single-carrier frequency-division multiple access) symbol in the time domain and continuous subcarriers in the frequency domain, where for frame structure type 1, and are provided by Table 1.

[0052] Table 1. Frame structure type 1 supported and combination

[0053] 2. NPUSCH mapping to physical resources

[0054] Each NPUSCH codeword can be mapped to N. RU One resource unit (RU), and repeat N times. Rep Next, N Rep Instructed by the network device. The complex-valued modulation symbols z(·) carried by the NPUSCH are mapped sequentially from z(0) to the subcarriers occupied by the NPUSCH transmission. Specifically, starting from the first time slot in the allocated RU, the frequency domain index k is mapped first, then the time domain index l, in ascending order to the resource unit RE(k,l) used for NPUSCH transmission.

[0055] Mapping to N slots After one time slot, before continuing to map z(·) on subsequent time slots, this N slots This time slot should be repeated additionally. Next, of which:

[0056] 3. Time slot index mapped to TB

[0057] NPUSCH in n NB-IoT uplink time slots i Send in i = 0, 1, ..., N-1, where N TB N represents the number of TBs to be scheduled. Rep N represents the number of repeated transmissions. RU The number of RUs for a 1TB mapping. This represents the number of NB-IoT uplink time slots included in the RU.

[0058] For N NB-IoT uplink time slots associated with 1 TB, it is further divided into time slot blocks consisting of B consecutive NB-IoT uplink time slots. The j-th time slot block associated with 1 TB corresponds to NB-IoT uplink time slot n. i Where i = jB + b, b = 0, 1, ..., B-1, j = 0, 1, ..., N Rep / L-1, And the redundant version RV of the NPUSCH application on the j-th time slot block is based on rv idx (j)=2·mod(rv DCI +j,2) is determined, where if L = 1; otherwise rv DCIThis refers to the RV indicated by DCI (Downlink Control Information). Furthermore, if the NPUSCH on the j-th time slot block is mapped to the allocated N... RU Time slots in each RU Then the NB-IoT uplink time slot n associated with this TB i Transmitted in, where for Δf = 3.75kHz, For Δf = 15kHz,

[0059] Furthermore, for the number of TBs N in the scheduling TB >1:

[0060] • If the terminal device is configured to interleave multiple TBs, and N Rep >C, where if C=1; otherwise C=4. Then the NB-IoT uplink time slot... With TB r+1 Association, where r = 0, 1, ..., N rB -1,l=0,1,…,g-1,c=0,1,…N Rep / C-1,

[0061] Otherwise, NB-IoT uplink time slot With TB r+1 Association, where r = 0, 1, ..., N TB -1,

[0062] 4. Time-domain OCC scheme

[0063] For the time-domain OCC scheme, the time-domain resources occupied by NPUSCH transmission are divided into OCC groups, and NPUSCH using OCC is sent based on the OCC groups. Different users perform code division multiplexing through OCC, thereby improving system capacity.

[0064] For inter-slot OCC, that is, applying OCC within the time slots occupied by NPUSCH transmission, as shown in Figure 2, the N NB-IoT uplink time slots occupied by NPUSCH transmission are divided according to the OCC length N. SF Divide into OCC groups, such as N SF =2, and multiply by the orthogonal sequence w within the OCC group. r (m), m=0,1…N SF -1. Different users use different OCC indexes r, thus enabling code division multiplexing within the OCC group.

[0065] For inter-symbol OCC, i.e. OCC is applied among symbols occupied by NPUSCH transmission, for example, as shown in FIG. 3, NB-IoT uplink symbols occupied by NPUSCH transmission are divided into OCC groups according to OCC length N SF OCC groups are divided, for example, N SF = 2, and multiplied by orthogonal sequences w r (m) in the OCC groups, m = 0, 1…N SF -1. Different users use different OCC indexes r, so as to realize code division multiplexing in the OCC groups.

[0066] It should be noted that symbols where DMRS (Demodulation Reference Signal) is located, for example, symbol #3, are not counted in the division of OCC groups.

[0067] In the NB-IoT system, the mapping of TB to NB-IoT uplink slots does not consider OCC, and therefore, when time domain OCC is applied, how to map TB to NB-IoT uplink slots is a problem to be solved urgently.

[0068] Please refer to FIG. 4, which shows a flowchart of an information mapping method provided by an embodiment of the present application. The method is executed by a terminal device. The method includes the following step 410.

[0069] Step 410: The terminal device maps one or more TBs using OCC, and an uplink channel associated with the one or more TBs is transmitted on N uplink time domain units mapped by the one or more TBs, where N is a positive integer.

[0070] In some embodiments, the terminal device transmits the uplink channel associated with the one or more TBs to a network device. Correspondingly, the network device receives the uplink channel associated with the one or more TBs.

[0071] In some embodiments, OCC is used to maintain orthogonality between signals, so as to improve the transmission efficiency of the system and reduce interference. In some embodiments, OCC distinguishes TBs in the same OCC group by different encoding, so as to realize code division multiplexing in the OCC group.

[0072] In some embodiments, the above-mentioned time domain unit can be a time domain unit in any communication system. In some embodiments, the time domain unit is used to describe a time domain resource. Exemplarily, the uplink time domain unit can be an uplink slot, an uplink frame, an uplink subframe, an uplink symbol, etc. In some embodiments, the symbol refers to an OFDM (Orthogonal Frequency-Division Multiplexing) symbol.

[0073] In some embodiments, the terminal device applies OCC to map the one or more TBs, and the terminal device determines the uplink time domain units in the N uplink time domain units to which the one or more TBs are mapped according to a length of the OCC. In some embodiments, the length of the OCC refers to a length of an OCC sequence.

[0074] In some embodiments, the uplink channel associated with the one or more TBs is a channel for transmitting uplink data. Illustratively, the uplink channel associated with the one or more TBs is a PUSCH. In some embodiments, the uplink channel associated with the one or more TBs is a NPUSCH. In some embodiments, the NPUSCH allows multiple users to transmit data on the same time and frequency resources, and multiple user multiplexing is achieved by using OCC, thereby improving spectral efficiency and system capacity. The design of the NPUSCH supports flexible time-frequency resource allocation, which can adapt to different service requirements and user characteristics.

[0075] In some embodiments, the terminal device determines the uplink time domain units in the N uplink time domain units to which the TBs are mapped according to one or more of the length of the OCC, the number of RUs, the number of uplink time domain units included in an RU, and the number of repeated transmissions of the one or more TBs.

[0076] In some embodiments, when the terminal device maps multiple TBs, the multiple TBs are interleaved and mapped in the time domain. Illustratively, the multiple TBs include TB1 and TB2, and the terminal device maps TB2 after mapping TB1 C times, where C is a positive integer. In some embodiments, C is predefined or preconfigured, or is indicated by the network device. For specific details of C, refer to the content of the embodiments below, which will not be described here.

[0077] In some embodiments, of the N uplink time domain units, B consecutive uplink time domain units used to map a first TB of the one or more TBs constitute a first uplink time domain unit block, and B is a positive integer less than or equal to N. In some embodiments, the first TB is any one of the one or more TBs.

[0078] In some embodiments, in a NB-IoT system, the terminal device applies OCC to map one or more TBs.

[0079] In some embodiments, the terminal device can apply inter-uplink time domain unit OCC, and can also apply inter-sub-uplink time domain unit OCC. Exemplarily, the uplink time domain unit is an uplink time slot, and the sub-uplink time domain unit is an uplink symbol. The terminal device can apply inter-uplink time slot OCC, and can also apply inter-uplink symbol OCC. In some embodiments, the inter-uplink time domain unit OCC refers to that at least one uplink time domain unit is included in one OCC group, and each uplink time domain unit maps the same data symbol. The inter-sub-uplink time domain unit OCC refers to that at least one sub-uplink time domain unit is included in one OCC group, and each sub-uplink time domain unit maps the same data symbol. The data symbol refers to a data symbol included in a TB, and is obtained after the uplink data is encoded and modulated.

[0080] The technical scheme provided by the embodiments of the present application provides a TB mapping scheme of OCC. The terminal device maps one or more TBs to uplink time domain units by using OCC, so that the terminal device can also apply OCC technology in the process of uplink data transmission with the network device, and the orthogonality between the one or more TBs is maintained, thereby improving the transmission efficiency of the system and reducing interference.

[0081] The embodiments of the present application also provide exemplary embodiments for how the terminal device applies OCC to map one or more TBs. Next, the process of applying OCC to map the first TB by the terminal device will be described by taking the first TB as an example.

[0082] In some embodiments, B continuous uplink time domain units in the N uplink time domain units constitute a first uplink time domain unit block, the first uplink time domain unit block is used to map the first TB, and B is a positive integer less than or equal to N.

[0083] In order to facilitate description, the first TB in the one or more TBs will be described next. The first TB can be any one of the one or more TBs. In the following embodiments, the first uplink time domain unit is taken as a time slot, the first uplink time domain unit block is taken as a time slot block, and the uplink time domain unit group is taken as an OCC group for exemplary description.

[0084] In some embodiments, B is determined based on a first value, a RU quantity, and a quantity of uplink time domain units included in the RU.

[0085] In some embodiments, the first value can be represented as L, the RU quantity can be represented as N RU , and the quantity of uplink time domain units included in the RU can be represented as

[0086] In some embodiments,

[0087] In some embodiments, the first value is determined based on the number of subcarriers if OCC is not applied. In some embodiments, the number of subcarriers can be denoted as In some embodiments, (i.e., single subcarrier), L = 1; (i.e., multiple subcarriers), where N Rep represents the number of repetitions of the first TB.

[0088] In some embodiments, the first value is determined based on the length of OCC if OCC is applied.

[0089] In some embodiments, the first value is equal to the length of OCC. In this case, i.e., L = N SF In some embodiments, may be determined by Table 1, which will not be repeated herein.

[0090] Exemplarily, as shown in FIG. 5, for (i.e., single subcarrier NPUSCH transmission), then Assuming N RU = 1, if OCC is not applied, then L = 1, and 1 time slot block contains time slots; if inter-time domain unit OCC (e.g., inter-time slot OCC) is applied, and the OCC length N SF = 2, then 2 time slots in the same OCC group transmit the same data symbol, and 1 time slot block contains time slots.

[0091] Exemplarily, as shown in FIG. 6, for (i.e., single subcarrier NPUSCH transmission), then Assuming N RU = 1, if inter-time domain unit OCC (e.g., inter-symbol OCC) is applied, and the OCC length N SF = 2, then 2 symbols in the same OCC group transmit the same data symbol, and 1 time slot block contains time slots.

[0092] In some embodiments, the first value is determined based on the number of repetitions of the first TB if OCC is applied. In some embodiments, the first value is determined based on a first repetition number, which is determined based on the number of repetitions of the first TB. In some embodiments, the first value is equal to the first repetition number. In some embodiments, the first repetition number can be denoted as

[0093] In some embodiments, the first value is determined based on the number of repetitions (N Rep In some embodiments, the terminal device determines that the first block of uplink time domain units contains uplink time domain units, i.e. wherein, is determined based on the number of repetitions (N Rep ) of the first TB.

[0094] In some embodiments, That is,

[0095] In some embodiments, in the case that the first value is determined based on the number of repetitions of the first TB, reference can be made to the description in the above related art, which will not be repeated here.

[0096] However, at this time, the relationship between the length of the OCC and the first value needs to be considered, so as to ensure that there are enough time domain resources in one group of uplink time domain units to realize code division multiplexing based on the OCC.

[0097] Exemplarily, as shown in FIG. 7, for then Assuming that N RU = 2 and N Rep = 4, the terminal device determines that that is, one time slot block contains uplink time domain units. Considering that the data symbols of one TB need to be mapped to uplink time domain units, therefore, the maximum OCC length supported by one time slot block is that is, N SF ≤ L, so as to ensure that after applying the OCC with N SF = 2, the number of time slots contained in one time slot block can map one complete TB. If the length of the OCC is greater than the first value, such as N SF = 3, then after applying the OCC, the number of time slots B contained in one time slot block needs to be 12 to complete the mapping of the TB.

[0098] In some embodiments, if the OCC is applied, the first value is determined based on the length of the OCC and the number of repetitions of the first TB.

[0099] In some embodiments, in the case that the length of the OCC is less than or equal to the first repetition number, the first value is equal to the first repetition number. In some embodiments, in the case that the length of the OCC is greater than the first repetition number, the first value is equal to the length of the OCC. In some embodiments, the first repetition number is determined based on the number of repetitions of the first TB.

[0100] In some embodiments, the first value is determined based on a maximum value of the length of the OCC and the number of repeated transmissions of the first TB. In some embodiments,

[0101] Exemplarily, as shown in FIG. 8, for then Suppose N RU = 2, N Rep = 2, the terminal device first determines Rep according to N However, if the OCC length N SF = 2 is configured, L = N SF = 2 is required, so as to ensure that after the OCC of N SF = 2 is applied, the number of slots contained in one slot block is able to map one complete TB.

[0102] Exemplarily, as shown in FIG. 9, if N Rep = 4, the terminal device determines according to N Rep If N SF = 2 is configured, at this time and it is ensured that after the OCC of N SF = 2 is applied, the number of slots contained in one slot block is able to map one complete TB; however, if N SF = 4 is configured, L = N Sf = 4 is required, so as to ensure that after the OCC of N SF = 4 is applied, the number of slots contained in one slot block is able to map one complete TB.

[0103] Exemplarily, if N Rep = 8, the terminal device determines according to N Rep then at this time and it is ensured that no matter the OCC of N SF = 2 or N SF = 4 is applied, the number of slots contained in one slot block is able to map one complete TB. In addition, when N Rep > 8, the terminal device determines Rep according to N Rep is the same as the slot block determined when N idx = 8, which is not described herein again.

[0104] In some embodiments, after determining the one or more TBs respectively associated uplink time domain unit blocks, the terminal device determines the RV applied on the uplink time domain unit blocks based on the indexes of the uplink time domain unit blocks. In some embodiments, the RV applied on the uplink time domain unit blocks refers to the RV associated with the TB mapped on the uplink time domain unit blocks. In some embodiments, the RV associated with the first TB mapped on the first uplink time domain unit block is determined based on the index of the first uplink time domain unit block.

[0105] In some embodiments, rv idx (j) = 2 · mod(rv DCI + j, 2). Wherein, j is the index of the first uplink time domain resource block, rv idx (j) is the RV applied on the first uplink time domain resource block, rv DCI is the RV indicated by the DCI. Exemplarily, assuming rv DCI = 0, the terminal device determines that the RV applied on the NPUSCH on the time slot block j = 0 is rv idx (0) = 2 · mod(0 + 0, 2) = 0, the RV applied on the NPUSCH on the time slot block j = 1 is rv idx (1) = 2 · mod(0 + 1, 2) = 2.

[0106] In some embodiments, the above-mentioned DCI is the DCI used for scheduling the transmission of the one or more TBs. In some embodiments, the above-mentioned DCI can also not be the DCI used for scheduling the transmission of the one or more TBs.

[0107] Through the above-mentioned method, the terminal device can determine the first uplink time domain unit block mapped by the first TB based on at least one of the length of the OCC and the number of repeated transmissions of the first TB. It is guaranteed that the time domain resources within the first uplink time domain unit block can map 1 complete first TB after applying the OCC.

[0108] In some embodiments, the terminal device can apply the OCC between the uplink time domain units, or can apply the OCC between the sub-uplink time domain units. Next, the two cases will be described respectively.

[0109] 1. Apply OCC between uplink time domain units

[0110] In some embodiments, the first uplink time domain unit block includes one or more uplink time domain unit groups, and the data symbols of the first TB are repeatedly mapped on the uplink time domain units included in the uplink time domain unit groups.

[0111] In some embodiments, the uplink time domain unit can be implemented as a time slot, a time slot group, a time slot block, a frame, a subframe, etc., and the sub-uplink time domain unit can be implemented as a sub-unit of the uplink time domain unit. For example, the uplink time domain unit is a time slot, and the sub-uplink time domain unit is a symbol or a symbol group. For another example, the uplink time domain unit is a time slot group, and the sub-uplink time domain unit is a time slot. For another example, the uplink time domain unit is a frame, and the sub-uplink time domain unit is a subframe.

[0112] In some embodiments, each uplink time domain unit group includes M uplink time domain units, and M is a positive integer.

[0113] In some embodiments, M is a positive integer less than or equal to B.

[0114] In some embodiments, M is a positive integer less than or equal to the first value. In some embodiments, the first value is the number of times that the first TB is repeatedly mapped on the first uplink time domain unit block.

[0115] For ease of description, the first TB in the one or more TBs will be described in the following, which can be any one of the one or more TBs. In the following embodiments, the first uplink time domain unit is taken as a time slot, the first uplink time domain unit block is taken as a time slot block, and the uplink time domain unit group is taken as an OCC group (or a time slot group) for example.

[0116] In some embodiments, the first TB includes one or more first sub-TBs. In some embodiments, the data symbols corresponding to the first sub-TB are a subset of the data symbols corresponding to the first TB. In some embodiments, the union of the data symbols of the one or more first sub-TBs is the data symbols corresponding to the first TB.

[0117] In some embodiments, the one or more first sub-TBs are continuously mapped on the one or more uplink time domain unit groups. In some embodiments, the data symbols of the first sub-TB are repeatedly mapped on the uplink time domain units within the uplink time domain unit group associated with the first sub-TB. For example, as shown in FIG. 8, the first TB includes two first sub-TBs TB1 and TB2, the time domain symbols of TB1 are repeatedly mapped on time slot 0 and time slot 1 of OCC group 1, and the time domain symbols of TB2 are repeatedly mapped on time slot 2 and time slot 3 of OCC group 2.

[0118] In some embodiments, M is determined based on the first value. In some embodiments, M is equal to the first value. In some embodiments, the first value can be represented as L.

[0119] In some embodiments, in the case where M is equal to the first value, if the first TB is mapped to the uplink time domain units in the N allocated RUs RU uplink time domain units in the N allocated RUs the uplink channel associated with the first TB is on the uplink time domain unit ni Transmission in, among which, Where j is the index of the first uplink time domain resource block associated with the first TB, i is the index of the uplink time domain unit associated with the first TB among N uplink time domain units, and l is determined based on L. This refers to the uplink time domain unit associated with the first TB in the allocated N without applying OCC. RU The index in the uplink time domain cell of each RU.

[0120] For example, as shown in Figure 8, if N RU =2, L=2, then the terminal device determines that one time slot block contains There are 1 time slot. If OCC is applied between time slots, and the OCC length is N... SF =2, the first time slot group is the OCC group. The data symbols of TB are continuously mapped on the time slots between OCC groups, and repeatedly mapped on the time slots within the OCC group. At this time, for the NPUSCH on the time slot block j=0 associated with TB: if mapped to the allocated N RU =Time slots in 2 RUs Then the time slot in time slot block j=0 Up transfer, where b = 0, 1, ..., 7, l = 0, 1, that is, if TB maps to the allocated N RU If the NPUSCH associated with the TB is actually transmitted on time slots 0 / 1, 2 / 3, 4 / 5, and 6 / 7 in time slot block j=0, then the NPUSCH associated with the TB is transmitted on time slots 0 / 1, 2 / 3, 4 / 5, and 6 / 7 in time slot block j=0, respectively.

[0121] In some embodiments, M is determined based on the length of the OCC. In some embodiments, M is equal to the length of the OCC.

[0122] In some embodiments, where M is determined based on the length of OCC, after mapping X uplink time domain unit groups, the mapping of X uplink time domain unit groups is repeated A times, where A is an integer greater than or equal to 0 and X is a positive integer.

[0123] In some embodiments, X is less than or equal to B. In some embodiments, X is predefined or preconfigured, or may be indicated by the network device. Exemplarily, X is a DCI indication used for scheduling the one or more TBs. For example, X is a first DCI indication. In some embodiments, if the first TB is mapped to an allocated N RU In the uplink time domain unit of each RU, X is less than or equal to

[0124] In some embodiments, X is Integer division. In some embodiments, to ensure that after applying OCC, one uplink time domain unit group can map one complete TB, X needs to be divisible by... Divisible by.

[0125] In some embodiments, A is determined based on a first value and the length of OCC. In some embodiments, A = L / N SF -1.

[0126] In some embodiments, if the first TB is mapped to the allocated N RU Uplink time domain unit in each RU Then the uplink channel associated with the first TB in the uplink time domain unit n i Transmission in, of which Where j is the index of the first uplink time domain resource block associated with the first TB, i is the index of the uplink time domain unit associated with the first TB among N uplink time domain units, and l is determined based on L. This refers to the uplink time domain unit associated with the first TB in the allocated N without applying OCC. RU The index of the uplink time domain cell in each RU, k represents the number of times the mapping is repeated after mapping X uplink time domain cell groups.

[0127] For example, as shown in Figure 10, if N RU =2, L=4, X=2, then the terminal device determines that one time slot block contains There are 1 time slot. If OCC is applied between time slots, and the OCC length is N... SF =2, then the first time slot group is the OCC group. The data symbols of TB are continuously mapped on the time slots between OCC groups, and are repeatedly mapped on the time slots within the OCC group. After mapping X = 2 OCC groups, that is, in time slots 0-3, before continuing to map the data symbols of TB, the data symbols in time slots 0-3 are additionally repeated L / N. SF -1 = 1 time. That is to say, the data symbols in time slots 4-7 are the same as the data symbols in time slots 0-3.

[0128] At this point, for the NPUSCH on the time slot block j=0 associated with TB: if mapped to the allocated N RU =Time slots in 2 RUs Then the time slot in time slot block j=0 Up transfer, where b = 0, 1, ..., 15, l = 0, 1, k = 0, 1, that is, if TB maps to the allocated N RU= slots 0, 1, 2, 3 in 2 RUs, the NPUSCH associated with the TB is actually transmitted in slots 0 / 1 / 4 / 5, 2 / 3 / 6 / 7, 8 / 9 / 12 / 13, 10 / 11 / 14 / 15 in the slot group j = 0, respectively.

[0129] By the above method, the data symbols of a TB are continuously mapped among the uplink time domain unit groups of the uplink time domain unit block and repeatedly mapped on the uplink time domain units within the uplink time domain unit group, so as to apply inter-slot OCC within the uplink time domain unit group. In the case where the first number is greater than the length of the OCC, if the number of uplink time domain units contained in the uplink time domain unit group is equal to the length of the OCC, the (L / length of the OCC-1) additional repetitions are needed per X uplink time domain unit groups, so as to ensure that 1 uplink time domain unit group can map 1 complete TB after the OCC is applied.

[0130] 2. Apply OCC among sub-uplink time domain units

[0131] In some embodiments, the first uplink time domain unit block includes one or more sub-uplink time domain unit groups, and the data symbols of the first TB are repeatedly mapped on the sub-uplink time domain units included in the sub-uplink time domain unit group.

[0132] In some embodiments, the uplink time domain unit can be implemented as a slot, a slot group, a slot block, a frame, a subframe, etc., and the sub-uplink time domain unit can be implemented as a subunit of the uplink time domain unit. For example, the uplink time domain unit is a slot, and the sub-uplink time domain unit is a symbol or a symbol group. For another example, the uplink time domain unit is a slot group, and the sub-uplink time domain unit is a slot. For another example, the uplink time domain unit is a frame, and the sub-uplink time domain unit is a subframe.

[0133] In some embodiments, each sub-uplink time domain unit group includes M sub-uplink time domain units, and M is a positive integer.

[0134] In some embodiments, M is a positive integer less than or equal to B.

[0135] In some embodiments, M is a positive integer less than or equal to the first number, and the first number is the number of repetitions of the first TB on the first uplink time domain unit block.

[0136] For ease of description, the first TB in one or more TBs will be described in the following, and the first TB can be any one of the one or more TBs. In the following embodiments, the uplink time domain unit is taken as a slot, the first uplink time domain unit block is taken as a slot block, and the sub-uplink time domain unit group is taken as an OCC group (or a symbol group) as an example for illustrative description.

[0137] In some embodiments, the first TB comprises one or more first sub-TBs. In some embodiments, the data symbols of the first sub-TBs are a subset of the data symbols of the first TB. In some embodiments, the union of the data symbols of the one or more first sub-TBs is the data symbols of the first TB.

[0138] In some embodiments, the one or more first sub-TBs are mapped contiguously on the one or more sub-sets of uplink time domain units. In some embodiments, the data symbols of a first sub-TB are mapped repeatedly on the sub- uplink time domain units within the sub-set of uplink time domain units associated with the first sub-TB. Exemplarily, as shown in FIG. 11, the first TB comprises two first sub-TBs TB1 and TB2, the time domain symbols of TB1 are mapped repeatedly on symbol 0 and symbol 1 of OCC group 1, and the time domain symbols of TB2 are mapped repeatedly on symbol 2 and symbol 4 of OCC group 2.

[0139] In some embodiments, M is determined based on the first value. In some embodiments, M is equal to the first value. In some embodiments, the first value can be denoted as L.

[0140] In some embodiments, in the case that M is equal to the first value, if the first TB is mapped to the uplink time domain units allocated in N RU RUs , the uplink channel associated with the first TB is transmitted in the uplink time domain unit n i , where n , where j is the index of the first uplink time domain resource block associated with the first TB, i is the index of the uplink time domain unit associated with the first TB in the N uplink time domain units, and l is determined based on L, is the index of the uplink time domain unit associated with the first TB in the uplink time domain units allocated in N RU RUs without applying OCC.

[0141] Exemplarily, as shown in FIG. 11, if N RU = 2 and L = 2, the terminal device determines that 1 slot block contains slots. If inter-symbol OCC is applied and the OCC length N SF = 2, the first symbol group is the OCC group, and the data symbols of the TB are mapped contiguously on the symbols between the OCC groups and repeatedly on the symbols within the OCC group. At this time, for the NPUSCH on the slot block j = 0: if it is mapped to the slots allocated in N RU = 2 RUs , the slot uplink time domain units, where b = 0, 1, …, 7, l = 0, 1, i.e., if the TB is mapped to slots 0, 1, 2, 3 in the allocated N RU = 2 RUs, the NPUSCH associated with the TB is actually transmitted in slots 0-1, 2-3, 4-5, 6-7 in slot block j = 0, respectively.

[0142] It should be noted that symbols 2-4 are included in the OCC group 2 in FIG. 11 because symbol 3 is the location of DMRS, and the symbol where DMRS is located is not counted in the division of the OCC group.

[0143] In some embodiments, M is determined based on the length of the OCC. In some embodiments, M is equal to the length of the OCC.

[0144] In some embodiments, where M is determined based on the length of the OCC, after mapping Y groups of sub-uplink time domain units, the Y groups of sub-uplink time domain units are repeated A times, A being an integer greater than or equal to 0, Y being a positive integer.

[0145] In some embodiments, Y is less than or equal to B. In some embodiments, Y is predefined or preconfigured, or can be indicated by the network device. Illustratively, Y is indicated by the DCI used to schedule the one or more TBs. For example, Y is indicated by the first DCI.

[0146] In some embodiments, Y = X * 3 * N SF In some embodiments, Y can also be determined based on X. In some embodiments, X is predefined or preconfigured, or can be indicated by the network device. In some embodiments, X is divisible by 3. In some embodiments, in order to ensure that after applying OCC, 1 group of uplink time domain units can map 1 complete TB, X needs to be divisible by 3.

[0147] In some embodiments, where M is determined based on the length of the OCC, after mapping X * 3 * N SF groups of sub-uplink time domain units, the X * 3 * N SF groups of sub-uplink time domain units are repeated A times, A being an integer greater than or equal to 0, X being a positive integer.

[0148] In some embodiments, A is determined based on the first value and the length of the OCC. In some embodiments, A = L / N SF - 1.

[0149] In some embodiments, if the first TB is mapped to uplink time domain units in the allocated N RU RUs The uplink channel associated with the first TB is transmitted in the uplink time domain unit n i , wherein wherein j is an index of the first uplink time domain resource block associated with the first TB, i is an index of the uplink time domain unit associated with the first TB in the N uplink time domain units, and l is determined based on L, is an index of the uplink time domain unit associated with the first TB in the N RU uplink time domain units in the allocated RUs without applying OCC, and k represents the number of times of repeated mapping after mapping 2 uplink time domain unit groups. In the above embodiment, only X is taken as an example for description, and X in the formula can also be replaced by Y / 3*N SF .

[0150] Exemplarily, as shown in FIG. 12, if N RU = 2, L = 4, and X = 2, the terminal device determines that 1 slot block contains N SF = 2, the first symbol group is an OCC group, and the data symbols of the TB are continuously mapped on the symbols between the OCC groups and repeatedly mapped on the symbols in the OCC group. Moreover, after mapping X*3*N SF = 12 OCC groups, that is, slots 0-3, the data symbols on the slots 0-3 are additionally repeated L / N SF -1 = 1 times before the data symbols of the TB continue to be mapped. That is, the data symbols on the slots 4-7 are the same as the data symbols on the slots 0-3.

[0151] At this time, for the NPUSCH on the slot block j = 0 associated with the TB: if the slot RU N = 2 RU is mapped to the slot , wherein b = 0, 1, …, 15, l = 0, 1, and k = 0, 1, that is, if the TB is mapped to the slots 0, 1, 2, and 3 in the N RU = 2 RU, the NPUSCH associated with the TB is actually transmitted in the slots 0-1 / 4-5, 2-3 / 6-7, 8-9 / 12-13, and 10-11 / 14-15 in the slot block j = 0, respectively.

[0152] By the above method, the data symbols of the TB are continuously mapped among the sub uplink time domain unit groups of the uplink time domain unit block, and repeatedly mapped on the sub uplink time domain units within the sub uplink time domain unit group, so as to realize the application of inter-time-slot OCC within the sub uplink time domain unit group. In the case where the first number is greater than the length of the OCC, if the number of sub uplink time domain units contained in the sub uplink time domain unit group is equal to the length of the OCC, the (L / OCC length-1) sub uplink time domain unit groups need to be additionally repeated every X*3*N SF times, so as to ensure that 1 sub uplink time domain unit group can map 1 complete TB after the application of the OCC.

[0153] In the above embodiments, the data symbols of the TB are continuously mapped among the uplink time domain unit groups of the uplink time domain unit block, or the data symbols of the TB are continuously mapped among the sub uplink time domain unit groups of the uplink time domain unit block. As to how the plurality of TBs are continuously mapped among the uplink time domain unit groups (sub uplink time domain unit groups), the present application also provides exemplary embodiments.

[0154] In some embodiments, the plurality of TBs are interleavedly mapped in the time domain.

[0155] In some embodiments, the plurality of TBs are sequentially mapped. In some embodiments, after the mapping of the first TB in the plurality of TBs is completed, the TBs after the first TB are mapped.

[0156] In some embodiments, after the first TB in the plurality of TBs is mapped for C times, the TBs after the first TB are mapped, and C is a positive integer. The uplink time domain units occupied by the continuous mapping of the same TB for C times are referred to as one interleaving block.

[0157] In some embodiments, C is preconfigured. In some embodiments, C is pre-defined or pre-configured, or can be configured by the network device. Exemplarily, C can be configured by the network device through DCI.

[0158] In some embodiments, C is determined based on the length of the OCC.

[0159] In some embodiments, in the case of applying OCC to map the plurality of TBs, if the plurality of TBs are interleavedly mapped, the uplink time domain units in the N uplink time domain units are associated with the TBs r+1 , that is, the TBs r+1 are mapped to the uplink time domain units , wherein r=0, 1, …, N TB -1, l=0, 1, …, g-1, c=0, 1, …N Rep / C-1, Exemplarily, C=4 (i.e. preconfigured), or C=N SF(i.e., based on the length N of OCC) SF Sure).

[0160] For example, as shown in Figure 13, for but Assume N TB =2, N RU =1, N Rep =4, if N is applied SF =2 time slots OCC, and for N TB If 2 TBs are interleaved, then C = N. SF =2, At this time, the NB-IoT uplink time slot With TB r+1 The association is defined as follows: r = 0, 1, l = 0, 1, ..., 3, c = 0, 1, which represents the NB-IoT uplink time slots n0-n3 and n8-n. 11 Associated with TB1, NB-IoT uplink time slots n4-n7 and n 12 -n 15 Associated with TB2.

[0161] In some embodiments, the above-described interleaving mapping method is applicable to both uplink time domain unit OCC (such as time slot OCC) and sub-uplink time domain unit OCC (such as symbol OCC), which will not be elaborated further in this application.

[0162] Using the above method, for multiple time-interleaved data blocks (TBs), each TB is mapped C times before the next TB is mapped. This ensures that after applying OCC, the time-domain resources within each interleaved block can be mapped to one complete TB.
