Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0373] In some embodiments, a scheme 1, intra-symbol and inter-slot mechanism are combined:

[0374] In some embodiments, 1-1: consider intra-symbol OCC spreading combination of M UEs with inter-slot OCC multiplexing of N UEs, where M can be the intra-symbol OCC sequence length (the OCC sequence of length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence of length N can be referred to as OCC sequence #2). Thus, OCC multiplexing between M*N UEs can be achieved.

[0375] S1: In one slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (where the number of symbols contained in one block X = total number of resource elements (REs) on the same symbol / M), and occ sequence covering, based on OCC length = M.

[0376] S2: Generate the symbols transmitted on the first slot based on S1, and spread on N-1 slots; or, on N slots, perform rate-matching based on the same redundancy version and the same starting symbol position, while generating the transmission symbols on N slots based on S1. Based on this, the same symbols are carried on N slots. Further, each value of the OCC sequence of length N determined for the current user is covered on each spread slot, respectively.

[0377] S3: Assuming that one slot segment contains N slots, if the repetition number K indicated by the gNB is greater than N, then there are K / N slot segments. RV cycling can be performed between K / N slot segments, and the random variable sequence (RV sequence) can be {0, 2, 0, 2}, {0, 3, 0, 3}, or {0, 2, 3, 1}. Each slot segment generates data symbols based on S1 and S2.

[0378] Assuming the repetition number is 8, M = 4, N = 2, and the number of RBs = 1, one possible diagram is shown in FIG. 1b.

[0379] In some embodiments, a scheme 1 is provided, combining intra-symbol and inter-slot mechanisms:

[0380] In some embodiments, 1-2: consider intra-symbol OCC spreading combination for M UEs and inter-slot OCC multiplexing for N UEs, where M can be the intra-symbol OCC sequence length (the OCC sequence with length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence with length N can be referred to as OCC sequence #2), so that up to M*N UE OCC multiplexing is achieved. On this basis, consider combining with TBoMS mechanism to enhance the data transmission performance of a single link. Consider the following two different schemes:

[0381] 1-2-1: first perform inter-slot OCC spreading, and then perform transmission of multi-time slot transport block (TBoMS) on subsequent slots. Assume that the number of slots occupied by TBoMS is D (the D is the number of slots occupied by a single modulation symbol transmission, excluding the additional N-1 slots other than the first slot occupied by inter-slot OCC multiplexing within a time slot segment). Optionally, repetition is performed based on RV cycling.

[0382] S1: within a slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (where the number of symbols contained in a block X = total number of REs on the same symbol / M), and OCC sequence covering, based on OCC length = M.

[0383] S2: generate the symbols transmitted on the first slot based on S1, and perform spreading on N-1 slots; or, on N slots, perform rate-matching based on the same redundancy version and the same starting symbol position, while generating the transmission symbols on N slots based on S1. Based on this, N slots carry the same symbols. Further, each value of the OCC sequence with length N determined for the current user is covered to each spreaded slot, respectively.

[0384] S3: The end bit position + 1 based on S1 / 2 is taken as the start bit position, and rate-matching is performed based on the start bit position and the number of bits (or the number of available resources and the modulation order, etc.) that can be carried on the N+i-th slot (i = 1, 2, …, N). For the remaining processing on the N+i-th slot, follow S1 and S2.

[0385] S4: Based on S1 / 2 / 3, complete all symbol processing and transmission on D*N slots. That is, for the d*N+i-th slot (d = 2, 3, …, D), the same way as S3 is used to determine the start bit position of rate-matching.

[0386] S5:

[0387] S5-1: Assuming that a time slot segment contains N*D slots, optionally, the repetition number K indicated by the gNB is greater than N, then there are K / N time slot segments. RV cycling can be performed between the K / N time slot segments, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each time slot segment generates data symbols based on S1-S4.

[0388] S5-2: Alternatively, the repetition number K indicated by the gNB is N, in other words, the terminal does not expect the repetition number indicated by the gNB to be equal to the inter-slot OCC sequence length.

[0389] S5-3: Alternatively, the repetition number K indicated by the gNB is N*D, in other words, the terminal does not expect the repetition number indicated by the gNB to exceed the product of the number of slots occupied by TBoMS transmission and the inter-slot OCC length.

[0390] Based on S5-1, assuming that the repetition number is 4, M = 4, N = 2 (inter-slot OCC length), the number of RBs = 1, and the number of slots D occupied by TBoMS transmission is 2, then one possible diagram is shown in FIG. 1c.

[0391] In some embodiments, a scheme 1 is provided: intra-symbol and inter-slot mechanisms are combined:

[0392] In some embodiments, 1-2: Consider intra-symbol OCC spreading combination for M UEs and inter-slot OCC multiplexing for N UEs, where M can be the intra-symbol OCC sequence length (the OCC sequence with length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence with length N can be referred to as OCC sequence #2), so that M*N UE OCC multiplexing is achieved at most. On this basis, consider to combine with TBoMS mechanism to enhance the data transmission performance of single link. Consider the following two different schemes:

[0393] 1-2-2: First perform TBoMS, then perform inter-slot OCC spreading. Assume that the number of slots occupied by TBoMS is D. Optionally, perform repetition at the end.

[0394] S1: In a slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (where the number of symbols contained in a block X = total number of REs on the same symbol / M), and occ sequence covering based on OCC length = M.

[0395] S2: Generate the symbol on the first slot based on S1; in addition, determine the ending bit position + 1 of the rate-matching performed on the first slot as the starting bit position on the next slot, and perform rate-matching on the next slot based on the starting bit position and the number of bits that can be carried on the next slot (or the number of available resources and the modulation order, etc.). At the same time, generate the transmission symbol of the next slot based on S1.

[0396] S3: Based on S2, determine the transmission symbol on D slots, and it is conceivable that the position of the starting bit carried on each slot is the ending bit position + 1 in the previous slot.

[0397] S4: Determine each D slots as a slot segment, generate the transmission symbols on the first slot segment based on S1-S3, and spread on N-1 slot segments; or, on N slot segments, rate-match based on the same redundancy version, while generating the transmission symbols on N slot segments based on S1-S3. Based on this, the same transmission symbols are carried on N slot segments. Further, each value of the length-N occ sequence determined for the current user is covered to each spreaded slot segment, respectively.

[0398] S5:

[0399] S5-1: Assuming that a block contains N*D slots, optionally, the repetition number K indicated by gNB is greater than N, then there are K / N slot segments. RV cycling can be performed between K / N blocks, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each block generates data symbols based on S1-S4.

[0400] S5-2: Alternatively, optionally, the repetition number K indicated by gNB is equal to N, in other words, the terminal does not expect the repetition number indicated by gNB to be equal to the inter-slot OCC sequence length.

[0401] S5-3: Alternatively, optionally, the repetition number K indicated by gNB is equal to N*D, in other words, the terminal does not expect the repetition number indicated by gNB to exceed the product of the number of slots occupied by TBoMS transmission and the inter-slot OCC length.

[0402] Based on S5-1, assuming that the repetition number is 4, M=4, N=2 (inter-slot OCC length), the number of RBs=1, and the number of slots D occupied by TBoMS transmission is 2, then one possible diagram is shown in Figure 1d.

[0403] In some embodiments, a scheme 2 is provided: inter-symbol OCC spreading combined with inter-slot OCC multiplexing mechanism:

[0404] In some embodiments, inter-symbol OCC spreading combination for M UEs and inter-slot OCC multiplexing for N UEs are considered, where M can be the inter-symbol OCC sequence length (the OCC sequence with length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence with length N can be referred to as OCC sequence #2).

[0405] S1: Within one slot, the terminal performs: rate-matching, DFT symbol(s) spreading, and OCC sequence covering based on OCC length = M. The DFT symbol spreading can be single-symbol based spreading, or symbol-block based spreading. Similarly, the OCC sequence covering can be single-symbol based OCC sequence covering, i.e., one OCC sequence value covers one corresponding symbol; or symbol-block based OCC covering, i.e., one OCC sequence value covers one symbol-block. Take an example of symbols number = 6 in one slot for PUSCH transmission, and OCC length = 2, single-symbol based spreading and symbol-block based spreading are illustrated respectively as shown in 1e.

[0406] S2: Generate the symbols for transmission on the first slot based on S1, and spread on N-1 slots; or, perform rate-matching on N slots based on the same redundancy version, while generating the transmission symbols on N slots based on S1. Based on this, the same symbols are carried on N slots. Further, each value of the OCC sequence with length N determined for the current user is covered to each spreaded slot.

[0407] S3: Assume that one slot segment contains N slots, and the repetition number K indicated by gNB is larger than N, then there are K / N slot segments. RV cycling can be performed between K / N slot segments, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each slot segment generates data symbols based on S1 and S2.

[0408] Assume that the repetition number is 4, M = 2 (inter-symbol OCC length), N = 2 (inter-slot OCC length), and the number of symbols for carrying data in one slot is 6 (only as an example, without considering DMRS symbols), taking single-symbol based spreading as an example, a possible diagram is shown in FIG. 1f.

[0409] In some embodiments, a scheme 2 is provided: inter-symbol OCC spreading combined with inter-slot OCC multiplexing mechanism.

[0410] In some embodiments, inter-symbol OCC spreading combination of M UEs and inter-slot OCC multiplexing of N UEs are considered, where M can be the inter-symbol OCC sequence length (the OCC sequence with length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence with length N can be referred to as OCC sequence #2). On this basis, combination with TBoMS mechanism is considered to enhance the data transmission performance of a single link. Two different schemes are considered as follows:

[0411] 1-2-1: inter-slot OCC spreading is performed first, and then symbol determination and transmission based on TBoMS PUSCH are performed. Assume that the number of slots occupied by TBoMS is D. Optionally, repetition is performed at the end.

[0412] S1: In one slot, the terminal performs: rate-matching, DFT symbol(s) spreading, and occ sequence covering based on OCC length=M. Wherein, the DFT symbol spreading can be single-symbol based spreading, or symbol-block based spreading. Similarly, the OCC sequence covering can be single-symbol based OCC sequence covering, i.e. one OCC sequence value covers one corresponding symbol; or symbol-block based OCC covering, i.e. one OCC sequence value covers one symbol-block.

[0413] S2: Generate the symbols transmitted on the first slot based on S1, and spread on N-1 slots; or, on N slots, perform rate-matching based on the same redundancy version, while generating the transmission symbols on N slots based on S1. Based on this, the same symbols are carried on N slots. Further, each value of the OCC sequence of length N determined for the current user covers each spread slot.

[0414] S3: Take the end bit position+1 based on S1 / 2 as the start bit position, and perform rate-matching based on the start bit position and the number of bits (or the number of available resources and the modulation order, etc.) that can be carried on the N+i-th slot (i=1,2,…,N). For the remaining processing flow of the data symbols on the N+i-th slot, follow S1 and S2.

[0415] S4: Complete all symbol processing and transmission on D*N slots based on S1 / 2 / 3. That is, for the d*N+i-th slot (d=2,3,..D), use the same way as S3 to determine the start bit position of rate-matching.

[0416] S5:

[0417] S5-1: Assume that one slot segment contains N*D slots, optionally, gNB indicates repetition number K is larger than N, then there are K / N slot segments. RV cycling can be performed between K / N slot segments, RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each slot segment performs data symbol generation based on S1~S4.

[0418] S5-2: Alternatively, optionally, gNB indicates repetition number K = N, in other words, terminal does not expect repetition number and inter-slot OCC sequence length are not equal.

[0419] S5-3: Alternatively, optionally, gNB indicates repetition number K = N*D, in other words, terminal does not expect repetition number exceeds the product of slot number occupied by one TBoMS transmission and inter-slot OCC length.

[0420] Based on S5-1, assume repetition number is 4, M = 2 (inter-symbol OCC length), N = 2 (inter-slot OCC length), number of slots for TBoMS PUSCH = 2 (not considering slots occupied by inter-slot OCC), number of symbols for carrying data in one slot is 6 (only as an example, not considering DMRS symbol), taking single-symbol based spreading as an example, one possible illustration is shown in Fig. 1g.

[0421] In some embodiments, a scheme 2 is provided, inter-symbol OCC spreading is combined with inter-slot OCC multiplexing mechanism:

[0422] Consider inter-symbol OCC spreading combination of M UEs and inter-slot OCC multiplexing of N UEs, where M can be the inter-symbol OCC sequence length (the OCC sequence of length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence of length N can be referred to as OCC sequence #2). On this basis, consider the combination with TBoMS mechanism to enhance the data transmission performance of single link. Consider the following two different schemes:

[0423] 1-2-2: First, perform symbol determination and transmission of TBoMS PUSCH, then perform determination of time domain resource position of inter-slot OCC, assuming that the number of slots occupied by TBoMS is D. Optionally, finally perform repetition.

[0424] S1: In a slot, the terminal performs rate-matching, DFT symbol(s) spreading, and OCC sequence covering based on OCC length = M. The DFT symbol spreading can be single-symbol based spreading, or symbol-block based spreading. Similarly, the OCC sequence covering can be single-symbol based OCC sequence covering, i.e., one OCC sequence value covers one corresponding symbol; or it can also be symbol-block based OCC covering, i.e., one OCC sequence value covers one symbol-block.

[0425] S2: Generate the symbol on the first slot based on S1; in addition, determine the ending bit position + 1 of the rate-matching performed on the first slot as the starting bit position on the next slot, and perform rate-matching on the next slot based on the starting bit position and the number of bits that can be carried on the next slot (or the number of available resources and the modulation order, etc.). At the same time, generate the transmission symbol of the next slot based on S1

[0426] S3: Based on S2, the determination of the transmission symbols on D slots is completed. It is conceivable that the position of the starting bit carried on each slot is the position of the ending bit in the previous slot + 1.

[0427] S4: Determine that every D slots is a slot segment, generate the transmission symbols on the first slot segment based on S1-S3, and perform spreading on N-1 slot segments; or, perform rate-matching on N slot segments based on the same redundancy version, and generate the transmission symbols on N slot segments based on S1-S3. Based on this, the same transmission symbols are carried on N slot segments. Further, each value of the length N occ sequence determined for the current user is respectively covered to each spreading slot segment.

[0428] S5:

[0429] S5-1: Assuming that a block contains N*D slots, optionally, the repetition number K indicated by the gNB is greater than N, then there are K / N slot segments. RV cycling can be performed between K / N blocks, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each block generates data symbols based on S1-S4.

[0430] S5-2: Alternatively, the repetition number K indicated by the gNB is N, in other words, the terminal does not expect the repetition number indicated by the gNB to be equal to the inter-slot OCC sequence length.

[0431] S5-3: Alternatively, the repetition number K indicated by the gNB is N*D, in other words, the terminal does not expect the repetition number indicated by the gNB to exceed the product of the number of slots occupied by a TBoMS transmission once and the inter-slot OCC length.

[0432] Based on S5-1, assuming repetition number is 4, M=2 (inter-symbol OCC length), N=2 (inter-slot OCC length), number of slots for TBoMS PUSCH=2 (not considering slots occupied by inter-slot OCC), number of symbols within a slot for carrying data is 6 (just as an example, not considering DMRS symbols), taking single-symbol based spreading as an example, one possible illustration is shown in FIG. 1h.

[0433] In some embodiments, a scheme 3 is provided, in which intra-symbol OCC spreading is combined with inter-symbol OCC multiplexing mechanism:

[0434] In some embodiments, intra-symbol OCC spreading combination for M UEs is considered in combination with inter-symbol OCC multiplexing for N UEs, where M can be the inter-symbol OCC sequence length (the OCC sequence of length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence of length N can be referred to as OCC sequence #2).

[0435] S1: Within a slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (where the number of symbols included in one block X = total number of REs on the same symbol / M), and occ sequence covering, based on OCC length = M.

[0436] S2: generate symbols to be transmitted on the first symbol and spread on N-1 symbols; or, generate symbols to be transmitted on the first symbol block (assuming there are P symbols in a symbol block) and spread on N-1 symbol blocks in units of symbol blocks. Based on this, the same symbols are carried between N symbols or N symbol blocks. Further, each value of the OCC sequence of length N determined for the current user is covered on each spread symbol or symbol block, respectively.

[0437] S3: assuming the repetition number indicated by the gNB is K, RV cycling can be performed between K repetitions, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. The data symbols carried in each slot are generated based on S1 and S2.

[0438] Assuming the repetition number is 4, M = 4 (intra-symbol OCC length), N = 2 (inter-symbol OCC length), the number of RBs = 1, and there are 6 symbols in a slot for carrying data, a possible diagram is shown in Figure 1i in units of single symbols.

[0439] In some embodiments, a scheme 3 is provided, in which intra-symbol OCC spreading is combined with inter-symbol OCC multiplexing mechanism:

[0440] In some embodiments, consider intra-symbol OCC spreading of M UEs combing with inter-symbol OCC multiplexing of N UEs, where M can be the inter-symbol OCC sequence length (the OCC sequence of length M can be referred to as OCC sequence #1), and N can be the inter-slot OCC sequence length (the OCC sequence of length N can be referred to as OCC sequence #2). On this basis, consider to combine with TBoMS mechanism to enhance the data transmission performance of single link. Consider the following transmission scheme: first determine the intra-slot transmission symbols, then determine and transmit the symbols based on TBoMS PUSCH. Assume that the number of slots occupied by TBoMS is D. Finally, perform repetition.

[0441] S1: In one slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (where the number of symbols contained in one block X = total number of REs on the same symbol / M), and occ sequence covering based on OCC length = M.

[0442] S2: Generate the symbols to be transmitted on the first symbol based on S1, and perform spreading on N-1 symbols; or, generate the symbols to be transmitted on the first symbol block (assuming there are P symbols in one symbol block) in symbol block units, and perform spreading on N-1 symbol blocks. On this basis, the same symbol is carried between N symbols or N symbol blocks. Further, each value of the OCC sequence of length N determined by the current user is respectively covered to each spreaded symbol or symbol block.

[0443] S3: generate the symbols on the first slot based on S1 / S2; in addition, determine the ending bit position + 1 as the starting bit position on the next slot when performing rate-matching, and perform rate-matching on the next slot based on the starting bit position and the number of bits (or the number of available resources and the modulation order, etc.) that can be carried on the next slot. At the same time, generate the transmission symbols of the next slot based on S1.

[0444] S4: based on S3, complete the determination of the transmission symbols on D slots. It is conceivable that the position of the starting bit carried on each slot is the ending bit position + 1 in the previous slot.

[0445] S5: determine that every D slots is a slot segment. Assuming that the repetition number indicated by the gNB is K, RV cycling can be performed between K repetitions, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each repetition occupies a time slot segment. The data symbols carried by each time slot segment are generated based on S1-S4. The starting code bit positions used when performing rate-matching on the starting slots of different time slot segments are different, that is, the redundancy versions are different. In the same time slot segment, different slots also use different starting bits. The specific determination method of the starting bits is shown in S4.

[0446] Assuming that the repetition number is 4, M = 2 (intra-symbol OCC length), N = 2 (inter-symbol OCC length), the number of RBs = 1, the number of slots occupied by a single TBoMS = 2, and the number of symbols for carrying data in a slot is 6, spreading is performed in single symbol units. A possible diagram is shown in FIG. 1j.

[0447] In some embodiments, a scheme 4 is provided, which combines intra-symbol, inter-symbol and inter-slot mechanisms:

[0448] In some embodiments, consider intra-symbol OCC spreading with OCC length M (assume OCC sequence is denoted by Seq#(1,X)), inter-symbol OCC multiplexing with OCC length N (assume OCC sequence is denoted by Seq#(2,X)), and inter-slot OCC multiplexing with OCC length L (assume OCC sequence is denoted by Seq#(3,X)).

[0449] S1: Within one slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (wherein the number of symbols contained in one block X = total number of REs on one symbol / M), and OCC sequence covering, based on OCC length = M.

[0450] S2: Generate the symbols to be transmitted on the first symbol and spread them on N-1 symbols; or, generate the symbols to be transmitted on the first symbol block (assume there are P symbols in one symbol block) and spread them on N-1 symbol blocks, in units of symbol blocks. Based on this, the same symbols are carried between N symbols or N symbol blocks. Further, each value of the OCC sequence of length N determined by the current user is respectively covered to each spreaded symbol or symbol block. In the same way, generate the symbols to be transmitted on the rest of the time domain resources until the generation of the symbols to be transmitted on all time domain resources in one slot is completed.

[0451] S3: Generate the symbols to be transmitted on the first slot and spread them on L-1 slots; or, perform rate-matching on L slots based on the same redundancy version, while generating the transmission symbols on L slots based on S1. Based on this, the same symbols are carried on L slots. Further, each value of the OCC sequence of length L determined by the current user is respectively covered to each spreaded slot.

[0452] S4: Assume one slot segment contains L slots, gNB indicates repetition number K is larger than N, then there are K / L slot segments. RV cycling can be performed between K / L slot segments, RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each slot segment is based on S1~S3 to generate data symbols.

[0453] Assume repetition number is 8, M=2 (intra-symbol OCC length), N=2 (inter-symbol OCC length), L=2 (inter-slot OCC length), RB number=1, one slot contains 6 symbols to carry data, spreading is based on single symbol, one possible illustration is shown in Figure 1k.

[0454] In some embodiments, a scheme 4 is provided, which combines intra-symbol, inter-symbol and inter-slot mechanisms:

[0455] In some embodiments, intra-symbol OCC spreading with OCC length M (assume OCC sequence is denoted by Seq#(1, X)), inter-symbol OCC multiplexing with OCC length N (assume OCC sequence is denoted by Seq#(2, X)), and inter-slot OCC multiplexing with OCC length L (assume OCC sequence is denoted by Seq#(3, X)) are considered. On this basis, TBoMS mechanism is considered to be combined to enhance the data transmission performance of a single link. Two different schemes are considered as follows:

[0456] First, inter-slot OCC multiplexing is performed, then TBoMS is performed. Finally, optionally, repetition is performed.

[0457] S1: In one slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (wherein the number of symbols contained in one block X = total number of REs on the same symbol / M), and OCC sequence covering based on OCC length = M.

[0458] S2: generate the symbols to be transmitted on the first symbol and spread them on N-1 symbols; or, generate the symbols to be transmitted on the first symbol block (assuming there are P symbols in a symbol block) and spread them on N-1 symbol blocks in a symbol block unit. Based on this, the same symbols are carried between N symbols or N symbol blocks. Further, each value of the OCC sequence of length N determined by the current user is covered on each spread symbol or symbol block, respectively. In the same way, the generation of the symbols to be transmitted on the remaining time domain resources is performed until the generation of the symbols to be transmitted on all time domain resources in a slot is completed.

[0459] S3: generate the symbols to be transmitted on the first slot and spread them on L-1 slots; or, perform rate-matching on L slots based on the same redundancy version, while generating the transmission symbols on L slots based on S1. Based on this, the same symbols are carried on L slots. Further, each value of the OCC sequence of length L determined by the current user is covered on each spread slot.

[0460] S4: take the ending bit position + 1 obtained based on S1 / 2 as the starting bit position, and perform rate-matching based on the starting bit position and the number of bits (or the number of available resources and the modulation order, etc.) that can be carried on the L+i-th slot (i = 1, 2, …, L). For the remaining processing procedure of the data symbols on the L+i-th slot, follow S1 and S2.

[0461] S5: complete the symbol processing and transmission on D*L slots based on S1 / 2 / 3 / 4. That is, for the d*L+i-th slot (d = 2, 3, …, D), the starting bit position of rate-matching is determined in the same way as S4.

[0462] S6:

[0463] S6-1: Assume one slot segment contains L*D slots, optionally, gNB indicates repetition number K is larger than L, then there are K / L slot segments. RV cycling can be performed among K / L slot segments, RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each slot segment is based on S1~S4 to generate data symbols.

[0464] S6-2: Alternatively, gNB indicates repetition number K = L, in other words, terminal does not expect gNB indicates repetition number is not equal to inter-slot OCC sequence length.

[0465] S6-3: Alternatively, gNB indicates repetition number K = L*D, in other words, terminal does not expect gNB indicates repetition number exceeds the product of the number of slots occupied by one TBoMS transmission and inter-slot OCC length.

[0466] Based on S6-1, assume repetition number is 4, M = 2 (intra-symbol OCC length), N = 2 (inter-slot OCC length), number of slots for TBoMS PUSCH = 2 (not considering slots occupied by inter-slot OCC), number of symbols for carrying data in one slot is 6 (only as an example, not considering DMRS symbols), L = 2, take single-symbol based spreading as an example, one possible illustration is shown in Figure 1l.

[0467] In some embodiments, a scheme 4 is provided, considering intra-symbol OCC spreading with OCC length M (assume OCC sequence is denoted by Seq#(1, X)), inter-symbol OCC multiplexing with OCC length N (assume OCC sequence is denoted by Seq#(2, X)), and inter-slot OCC multiplexing with OCC length L (assume OCC sequence is denoted by Seq#(3, X)). On this basis, it is considered to combine with TBoMS mechanism to enhance the data transmission performance of single link. Two different schemes are considered as follows:

[0468] 4-2: First, the symbol determination and transmission of TBoMS PUSCH is performed, then the time domain resource position determination of inter-slot OCC is performed, assuming the number of slots occupied by TBoMS is D. Optionally, finally, repetition is performed.

[0469] S1: Within one slot, the terminal first performs: rate-matching, block-wise modulation symbol spreading (wherein the number of symbols contained in one block X = total number of REs on one symbol / M), and occ sequence covering based on OCC length = M.

[0470] S2: Based on S1, the symbols transmitted on the first symbol are generated and spread on N-1 symbols; or, in symbol block units, the symbols to be transmitted on the first symbol block are generated (assuming there are P symbols in one symbol block), and spread on N-1 symbol blocks. Based on this, the same symbols are carried between N symbols or N symbol blocks. Further, each value in the OCC sequence of length N determined by the current user is covered on each spread symbol or symbol block. In the same way, the generation of the symbols to be transmitted on the remaining time domain resources is performed until the generation of the symbols to be transmitted on all time domain resources in one slot is completed.

[0471] S3: Based on S1, the symbols on the first slot are generated; in addition, the ending bit position + 1 of the rate-matching performed on the first slot is determined as the starting bit position on the next slot, and the rate-matching of the next slot is performed based on the starting bit position and the number of bits that can be carried on the next slot (or the number of available resources and the modulation order, etc.). At the same time, based on S1, the transmission symbols of the next slot are generated.

[0472] S4: Based on S2, the determination of the transmission symbols on D slots is completed, and it is conceivable that the starting bit position carried on each slot is the ending bit position + 1 in the previous slot.

[0473] S5: Determine each D slots as a slot segment, generate the symbols to be transmitted on the first slot segment based on S1-S3, and spread on L-1 slot segments; or, on L slot segments, rate-match based on the same redundancy version, while generating the symbols to be transmitted on L slot segments based on S1-S3. Based on this, N slot segments carry the same transmission symbols. Further, each value of the length N occ sequence determined for the current user is covered on each slot segment of spreading, respectively.

[0474] S6:

[0475] S6-1: Assuming that a block contains L*D slots, optionally, the repetition number K indicated by the gNB is greater than L, then there are K / L slot segments. RV cycling can be performed between K / L blocks, and the RV sequence can be {0, 2, 0, 2}, {0, 3, 0, 3} or {0, 2, 3, 1}. Each block generates data symbols based on S1-S4.

[0476] S6-2: Alternatively, optionally, the repetition number K indicated by the gNB is equal to L, in other words, the terminal does not expect the repetition number indicated by the gNB to be equal to the inter-slot OCC sequence length.

[0477] S6-3: Alternatively, optionally, the repetition number K indicated by the gNB is equal to L*D, in other words, the terminal does not expect the repetition number indicated by the gNB to exceed the product of the number of slots occupied by a TBoMS transmission once and the inter-slot OCC length.

[0478] Based on S6-1, assuming that the repetition number is 4, M=2 (intra-symbol OCC length), N=2 (inter-symbol OCC length), L=2 (inter-slot OCC length), the number of RBs=1, the number of symbols for carrying data in a slot is 6, spreading is performed in single symbol units, D=2, then one possible diagram is shown in Figure 1m.

[0479] In some embodiments, considering that the coverage range of a non-terrestrial network (NTN) cell is large, 8 UE multiplexing is not completely excluded from the current consideration in order to effectively improve the system capacity / throughput. For PUSCH capacity enhancement, a feasible solution is to perform OCC based on PUSCH repetition type A, that is, to introduce inter-slot based OCC multiplexing. However, one disadvantage of this solution is that the link performance of a single user is poor when 8 UE multiplexing is considered, considering the influence of channel time variation. In addition, pre-DFT based OCC spreading or inter-symbol OCC spreading can also be considered. However, one limitation of these two solutions is that the influence and limitation on resource allocation are great. Therefore, a solution of combining a multi-OCC scheme can be considered to support more user multiplexing. On this basis, how to realize the configuration and indication of OCC multiplexing under the combination mechanism is a content that needs to be considered.

[0503] A twentieth mapping relationship is a relationship between an OCC sequence index and an OCC sequence length.

[0504] A twenty-first mapping relationship is a relationship determined based on the twentieth mapping relationship, an OCC mechanism, and an OCC sequence length of the OCC mechanism.

[0505] It should be noted that the configuration information can be non-essential information. For example, when the mapping relationship is determined based on a protocol preset rule, the configuration information is non-essential information.

[0506] In some embodiments, the network device sends first information to the terminal, and the first information is used to indicate the index.

[0507] In some embodiments, the network device sends second information to the terminal, and the second information is used to determine a mapping relationship corresponding to one OCC mechanism combination.

[0508] In some embodiments, the network device sends third information to the terminal, and the third information is used to indicate an OCC sequence length corresponding to at least one OCC mechanism.

[0509] In some embodiments, the network device sends fourth information to the terminal, and the fourth information is used to determine a first OCC mechanism combination.

[0510] In some embodiments, the network device sends fifth information to the terminal, and the fifth information is used to indicate an OCC sequence corresponding to at least one OCC mechanism.

[0511] Step S2102: The terminal determines an OCC parameter corresponding to an OCC mechanism.

[0512] In some embodiments, the terminal determines an OCC parameter corresponding to the OCC mechanism in an OCC mechanism combination; wherein the OCC mechanism combination contains at least two OCC mechanisms.

[0513] In some embodiments, the OCC mechanism includes at least one of the following:

[0514] An intra-symbol OCC mechanism;

[0515] An inter-symbol OCC mechanism;

[0516] inter-slot OCC mechanism.

[0517] In some embodiments, the OCC parameter is a parameter of an OCC sequence, and the parameter of the OCC sequence comprises at least one of:

[0518] OCC sequence length;

[0519] OCC sequence;

[0520] OCC sequence index, the OCC sequence index being used to indicate an OCC sequence.

[0521] In some embodiments, the OCC sequence comprises at least one of:

[0522] Walsh sequence;

[0523] Hadamard sequence;

[0524] DFT sequence.

[0525] In some embodiments, different OCC mechanisms adopt independent OCC sequences.

[0526] In some embodiments, for a block of determined time-frequency domain resources, the maximum number of multiplexed users X, the OCC sequence length M of the intra-symbol OCC mechanism, the OCC sequence length N of the inter-symbol OCC mechanism, and the OCC sequence length L of the inter-slot OCC mechanism satisfy the constraint relationship: X = M × N × L, wherein M, N, and L are positive integers.

[0527] Exemplarily, different OCC schemes have corresponding OCC sequence lengths. Assuming that at least one of the intra-symbol OCC (assuming OCC length M), the inter-symbol OCC (assuming OCC length N), and the inter-slot OCC (assuming OCC length L) is supported or configured, for a block of determined time-frequency domain resources, the maximum number of multiplexed users and the above three parameters satisfy the constraint relationship: Maximum number of UEs = M × N × L, wherein M, N, and L are positive integers. When at least one of M, N, and L is 1, it indicates that the corresponding OCC scheme is not supported or is not enabled.

[0528] In some embodiments, the OCC sequence length corresponding to the OCC mechanism is determined based on a protocol preset rule and / or configuration information sent by the network device.

[0529] In some embodiments, the configuration information can be configuration information or parameters sent by the network device, which is not limited herein.

[0530] In some embodiments, the OCC sequence length corresponding to the OCC mechanism is determined based on a protocol preset rule and / or configuration information sent by the network device.

[0531] For example, the OCC length is determined by a protocol preset rule or a protocol preset value. For example, in response to the terminal performing inter-slot OCC multiplexing, the OCC sequence length L is fixed as 2.

[0532] In some embodiments, the second OCC sequence length corresponding to the second OCC mechanism in the OCC mechanism combination is determined based on a protocol preset rule, a maximum multiplexing user number, and a first OCC sequence length of at least one first OCC mechanism.

[0533] In some embodiments, at least one of the maximum multiplexing user number and the first OCC sequence length of the at least one first OCC mechanism is determined based on the configuration information.

[0534] In some embodiments, at least one of the maximum multiplexing user number and the first OCC sequence length of the at least one first OCC mechanism is determined based on the protocol preset rule.

[0535] In some embodiments, the second OCC sequence length is determined by a protocol preset rule, a maximum multiplexing user number, and at least one first OCC sequence length. The different schemes in the foregoing schemes (scheme 1, scheme 2, scheme 3, and scheme 4) are described respectively. The maximum multiplexing user number and the at least one first OCC sequence length can be determined by network configuration or indication parameters (i.e., corresponding configuration information), or determined by a protocol preset manner. The determination manners of different first OCC sequence lengths can be different.

[0536] Exemplarily, for scheme 1, in response to the terminal determining to perform intra-symbol and inter-slot combining OCC multiplexing, the inter-slot OCC length L can be determined by a protocol preset value, or can be determined by network configuration. In addition, the maximum multiplexing user number can be determined by network configuration and / or indication parameter (i.e. corresponding configuration information). Based on this, the intra-symbol OCC length M can be determined by a protocol preset rule, for example, M = U / L.

[0537] Exemplarily, for scheme 2, in response to the terminal determining to perform inter symbol and inter-slot combining OCC multiplexing, the inter-slot OCC length L is determined by a protocol preset value, or is determined by network configuration. In addition, the maximum multiplexing user number can be determined by network configuration and / or indication parameter (i.e. corresponding configuration information). Based on this, the inter-symbol OCC length N can be determined by a protocol preset rule, for example, N = U / L.

[0538] Exemplarily, for scheme 3, in response to the terminal determining to perform intra-symbol and inter-symbol combining OCC multiplexing, the inter-symbol OCC length N and the maximum multiplexing user number are determined by network configuration or indication parameter (i.e. corresponding configuration information). Based on this, the intra-symbol OCC length M can be determined by a protocol preset rule, for example, M = U / N.

[0539] Exemplarily, for scheme 4, in response to the terminal determining to perform intra-symbol, inter-symbol and inter-slot combining OCC multiplexing. For example, the maximum multiplexing user number U and the intra-symbol OCC sequence length M are determined by configuration parameters of the gNB respectively, and the inter-slot OCC sequence length L is determined by a protocol preset value. Based on this, the inter symbol OCC length N can be determined by a protocol preset rule, for example, N = (U / M) / L.

[0540] In some embodiments, the determination manners of different first OCC sequence lengths are independent, which can be the same or different.

[0541] In some embodiments, a first mapping relationship between the index and OCC sequence lengths of the at least two OCC mechanisms is determined based on the protocol preset rule or the configuration information; OCC sequence lengths corresponding to the at least two OCC mechanisms in the OCC mechanism combination are determined based on the first information and the first mapping relationship, wherein the first information is information received from a network device, and the first information is used to indicate the index.

[0542] The following is described by way of example 1:

[0543] In some embodiments, the foregoing scheme 1 is described by way of example (only as an example, and other schemes such as scheme 2, scheme 3, or scheme 4 can also be used). It is assumed that the protocol preset supports the OCC scheme combination mechanism described in scheme 1. Then, the protocol can preset a sequence length combination table of different occ schemes under the combination mechanism (i.e., the first mapping relationship is determined based on the protocol preset rule).

[0544] In some embodiments, in response to the terminal determining to perform intra-symbol and inter-slot Combining OCC multiplexing, the terminal determines the sequence lengths of different OCC schemes based on a row in the table configured or indicated by the gNB (i.e., an index is indicated by the first information, and the index corresponds to a row in the table).

[0545] In some embodiments, the gNB can perform configuration or indication through radio resource control (RRC), media access control (MAC) control element (CE), or downlink control information (DCI) (i.e., the first information is sent through the above messages).

[0546] In some embodiments, if the configuration or indication is performed through the MAC CE, a new MAC CE (using a new logic channel identifier (LCID)) can be added, or an existing MAC CE can be reused, or a reserved field in the MAC subheader of the MAC service data unit (SDU) or the CE can be used for indication.

[0547] In some embodiments, if the indication is performed through the DCI, an existing field can be reused, or a new field can be added for indication.

[0548] In some embodiments, the multiplexing reuses at least part of bits of an existing field, including a frequency domain resource allocation (FDRA) field, a time domain resource allocation (TDRA) field, a frequency hopping flag (FH flag) field, a modulation and coding scheme (MCS) field, a transmission power control (TPC) field, an antenna port, and the like.

[0549] In some embodiments, the DCI can be a fallback DCI or a non-fallback DCI.

[0550] In some embodiments, for indication using the new field, the non-fallback DCI contains the new field in response to the OCC scheme combination mechanism being enabled, or the non-fallback DCI does not contain the new field in response to the OCC scheme combination mechanism being disabled.

[0551] In some embodiments, referring to Table 1, even if the OCC scheme combination mechanism is enabled, the index value of the OCC length table, for example, 4, can disable one or more of the OCC schemes participating in the combination, thereby realizing the use of independent OCC schemes. Alternatively, the protocol presets a gNB to always configure or indicate a row in the table (the table is always enabled), and the table also contains a row of all 1 values (that is, the OCC scheme sequence length of different OCC schemes is 1). The terminal disables the combination mechanism based on one of the rows configured or indicated by the gNB, and the previous embodiment will no longer apply (for the description of the new field).

[0552] Table 1:

[0553] In some embodiments, based on the protocol preset rule or the configuration information, a second mapping relationship between the index and the OCC sequence length of at least two OCC mechanisms in any OCC mechanism combination of the at least two OCC mechanism combinations is determined; based on the first information and one of the second mapping relationships determined based on the second information, the OCC sequence length corresponding to the at least two OCC mechanisms in the OCC mechanism combination is determined; wherein the first information and the second information are information received from a network device, the first information is used to indicate the index, and the second information is used to determine the second mapping relationship corresponding to one OCC mechanism combination.

[0554] It should be noted that the present disclosure can involve a plurality of OCC mechanism combinations, for example, 4 combinations, and the second information can further indicate one of the 4 combinations.

[0555] In some embodiments, a third mapping relationship between the index, at least two OCC mechanisms of the at least two OCC mechanism combinations, and OCC sequence lengths of the at least two OCC mechanisms of the at least two OCC mechanism combinations is determined based on the preset rules of the protocol or the configuration information; OCC sequence lengths corresponding to at least two OCC mechanisms in the OCC mechanism combination are determined based on the first information and the third mapping relationship; the first information is information received from a network device, and the first information is used to indicate the index.

[0556] The following is illustrated by Embodiment 2:

[0557] In some embodiments, the protocol preset is as described in the at least two schemes (at least two of the schemes 1, 2, 3, and 4) of the OCC scheme combination mechanism.

[0558] In some embodiments, if the sequence length combination table is preset by the protocol, different scheme combination mechanisms can have independent preset tables (corresponding to the second mapping relationship), or different schemes use a common occ sequence length combination table (corresponding to the third mapping relationship).

[0559] In some embodiments, in response to the terminal determining to perform intra-symbol and inter-slot Combining OCC multiplexing, the terminal determines the sequence length of different OCC schemes based on a row in a table configured or indicated by the gNB (i.e., the configuration information).

[0560] In some embodiments, the gNB can be configured or indicated by RRC, MAC CE, or DCI, etc.

[0561] In some embodiments, if the MAC CE is used, a new MAC CE (using a new LCID, or reusing an existing MAC CE) can be added, or a reserved field in the MAC subheader of the MAC SDU or CE can be used for indication.

[0562] In some embodiments, if indicated by the DCI, the existing fields can be reused, or a new field can be added for indication. The existing fields include at least part of the bits of the FDRA, TDRA, FH flag, MCS, TPC, antenna port, etc.

[0563] In some embodiments, the DCI can be a fallback DCI or a non-fallback DCI.

[0564] In some embodiments, for indication using a new field, the non-fallback DCI contains the new field in response to the OCC scheme combination mechanism being enabled, or the non-fallback DCI does not contain the new field in response to the OCC scheme combination mechanism being disabled.

[0565] In some embodiments, assuming that the protocol supports scheme 1 and scheme 2, two separate OCC length tables are preset in the protocol for the two different combination modes, and a possible example is shown in Tables 2 and 3 (corresponding to the second mapping relationship). The terminal needs to determine the combination mode of the OCC scheme based on an explicit or implicit manner, so as to determine which OCC length configuration table to use (the table of scheme 1 or the table of scheme 2, which can be indicated by the second information). In addition, one row in the two tables can contain all 1s (the values of different OCC lengths are all 1), in which case the gNB can dynamically signal the corresponding OCC scheme combination to be disabled or enabled.

[0566] Table 2:

[0567] Table 3:

[0568] In some embodiments, assuming that the protocol supports scheme 1 and scheme 2, one common OCC length table (corresponding to the third mapping relationship) is preset in the protocol for the two different combination modes, and a possible example is shown in Table 4.

[0569] Table 4:

[0570] Under this mechanism, which OCC scheme combination is used, or OCC scheme is enabled, can be determined based on the table index (i.e. the second information indication) configured or indicated by gNB, without the need of additional explicit enable or disable parameters indication. In addition, based on Table 4, the following way can also be supported: in the protocol, any combination of three OCC schemes (including the three ways used together) can also be supported. For example, gNB indicates to index 15 of the following table, which means all OCC schemes are disabled. Or, gNB indicates to index 0, which means the combination of inter-symbol and inter-slot occ is enabled, and intra-symbol occ scheme is disabled. Of course, if the protocol is preset, only scheme 1 and scheme 2, or independent OCC scheme (no combination), can be supported, then index 13 in Table 4 is an inappropriate example.

[0571] In some embodiments, the enabling or disabling of at least one of the OCC mechanisms in the OCC mechanism combination is determined based on a protocol preset rule and / or configuration information received from a network device.

[0572] In some embodiments, a fourth mapping relationship between an index and OCC sequence lengths of at least two OCC mechanisms is determined based on a protocol preset rule or the configuration information; the enabling or disabling of at least one of the OCC mechanisms in the OCC mechanism combination is determined based on the first information and the fourth mapping relationship; the first information is information received from a network device, and the first information is used to indicate the index.

[0573] In some embodiments, the OCC sequence length corresponding to at least one of the OCC mechanisms in the OCC mechanism combination is determined based on the first information and the fourth mapping relationship; the OCC sequence length is a first value, and the OCC mechanism corresponding to the OCC sequence length is disabled; the OCC sequence length is a second value, and the OCC mechanism corresponding to the OCC sequence length is enabled, and multi-terminal multiplexing is performed based on the OCC sequence length and the corresponding OCC mechanism.

[0574] In some embodiments, the fifth mapping relationship between the index, the OCC sequence length of at least two OCC mechanisms in any of the at least two OCC mechanism combinations is determined based on the preset rule of the protocol or the configuration information; and the enabling or disabling of at least one of the OCC mechanisms in the OCC mechanism combination is determined based on the first information and one of the fifth mapping relationships determined based on the second information, wherein the first information and the second information are information received from the network device, the first information is used to indicate the index, and the second information is used to determine one of the fifth mapping relationships corresponding to the OCC mechanism combination.

[0575] In some embodiments, the sixth mapping relationship between the index, at least two OCC mechanisms of the at least two OCC mechanism combinations, and the OCC sequence length of at least two OCC mechanisms of the at least two OCC mechanism combinations is determined based on the preset rule of the protocol or the configuration information; and the enabling or disabling of at least one of the OCC mechanisms in the OCC mechanism combination is determined based on the first information and the sixth mapping relationship, wherein the first information is information received from the network device, and the first information is used to indicate the index.

[0576] The following is exemplarily illustrated by Embodiment 3: the gNB configures the OCC length joint table of the OCC scheme combination.

[0577] In some embodiments, the determination of the OCC length of different OCC schemes, and / or the enabling or disabling of different OCC schemes, and the enabling or disabling of the OCC scheme combination is performed based on one row in the signaling indication table (i.e., indicated by the first information) such as the MAC CE, the MAC subheader, or the DCI.

[0578] In some embodiments, the protocol only supports one of the OCC scheme combinations (one of Scheme 1, Scheme 2, Scheme 3, and Scheme 4). Then the gNB configures the configurable OCC length table as shown in Embodiment 1. Different from Embodiment 1, the enabling and disabling of the OCC scheme combination can be directly indicated by the configuration of the OCC Sequence table without using additional parameters. For example, if the OCC scheme combination is disabled, the configuration of the OCC length table is not necessary. Or, if one of the OCC schemes in the OCC scheme combination is never enabled, the gNB can not configure the corresponding OCC length or configure the corresponding OCC length to always be 1 (the value in each row is 1). Or, one or several of the OCC schemes can be dynamically enabled or disabled (in some cases, only the remaining OCC schemes in the OCC scheme combination can be used except for the enabled OCC scheme).

[0579] In some embodiments, the protocol can support several of the OCC scheme combinations (several of Scheme 1, Scheme 2, Scheme 3, and Scheme 4). The specific configuration can be as shown in Embodiment 2, which can be configured as an independent OCC length table or a joint OCC length table. If configured as an independent OCC length table, only one of the OCC length tables for one direction can be configured at a time, or a table of several OCC scheme combinations can be semi-statically configured, and the OCC scheme combination table can be dynamically disabled or enabled or switched between OCC length tables by MAC CE or DCI. In addition, for the configuration of the joint OCC length table, as shown in Table 5, if one of the schemes (one of Scheme 1, Scheme 2, Scheme 3, and Scheme 4) is not enabled, then the OCC length of the other OCC schemes will not be 1, and the OCC length of all the OCC schemes under the corresponding OCC scheme combination (disabled OCC scheme combination) will not be 1.

[0580] In some embodiments, even if a certain OCC scheme combination is disabled, one or several schemes (a subset, not the full set) participating in the OCC scheme combination can be enabled. Further, assuming that the protocol supports scheme 1, scheme 2, scheme 3 and scheme 4, even if scheme 4 is configured to be disabled by RRC configuring the OCC length table, one or several (or all) of scheme 1, scheme 2 or scheme 3 can be semi-statically configured to be enabled (with the configuration of the corresponding OCC length), or one or several OCC schemes can be configured to be used independently. That is, with flexible RRC configuration, the protocol does not make restrictions.

[0581] Table 5:

[0582] In some embodiments, the gNB makes index indication of the specific OCC length table based on MAC CE, MAC subheader or DCI signaling. Specifically, the indication method based on MAC CE, MAC subheader or DCI is similar to that described in embodiment 1 or 2.

[0583] In some embodiments, the terminal receives a first message sent by the network device; wherein the first message contains the first information; the first message includes at least one of the following: a radio resource control (RRC) message; a medium access control (MAC) control element (CE) message; and a downlink control information (DCI) message.

[0584] In some embodiments, the terminal receives third information sent by the network device; wherein the third information is used to indicate the OCC sequence length corresponding to at least one of the OCC mechanisms.

[0585] In some embodiments, the terminal receives a second message sent by the network device; wherein the second message contains the third information; the second message includes at least one of the following: a radio resource control (RRC) message; a medium access control (MAC) control element (CE) message; and a downlink control information (DCI) message.

[0586] Exemplarily, the OCC length of at least one OCC scheme is determined by gNB configuration or indication.

[0587] For example, the signaling can be RRC signaling, DCI signaling or MAC CE, or the used signaling can be a combination between at least two of the above. For RRC configuration, for example, the RRC parameter takes one of the enumerated values (or indicated by bitmap, each bit corresponds to one OCC length), or the RRC parameter takes a codepoint, or the RRC signaling indicates one index of a pre-configured OCC length list. The DCI or MAC CE carries information similar to RRC, and the specific use of fields is similar to the third way. Alternatively, RRC and DCI can be combined to determine the OCC length, for example, RRC configures an OCC length list of an OCC scheme (for example, the OCC length list can contain the value of OCC length = 1), and DCI or MAC CE or MAC subheader indicates an index in the list (for example, if OCC length = 1 is indicated, it means that the OCC scheme is dynamically disabled).

[0588] In some embodiments, if the OCC lengths of multiple OCC schemes are determined by gNB configuration or indication, the OCC lengths of different OCC schemes are independently configured or indicated by gNB. For example, assuming that the intra-symbol OCC length is 2 and the inter-slot OCC length is 4 determined by the independent RRC parameters configured by gNB, it is conceivable that the intra-symbol and inter-slot combined OCC is used. In addition, the OCC scheme combination, or the enablement or disablement of one of the OCC schemes can be dynamically performed by DCI, MAC CE or MAC subheader. For example, still taking intra-symbol and inter-slot OCC as an example, two-bit enablement signaling is carried in DCI, which corresponds to intra-symbol occ and inter-slot occ respectively. The value "00" can represent that the above OCC scheme combination is dynamically disabled, and if the value is "10", it means that the intra-symbol OCC is enabled and the inter-slot OCC is disabled, and the terminal performs intra-symbol OCC with OCC length = 2.

[0589] In some embodiments, the OCC sequence length of different OCC mechanisms in the OCC mechanism combination is determined based on the first number of allocated resources. That is, the OCC length is determined by other implicit manners.

[0590] In some embodiments, the OCC length is determined by the number of allocated resources

[0591] In some embodiments, the OCC length is the largest integer that can divide the number of resources, or the OCC length is the smallest integer that can divide the number of resources.

[0592] Exemplarily, assuming that X time domain symbols are allocated in a slot, then for inter-symbol OCC, the OCC length = X / N, where N is the largest positive integer that can divide X, or N is the largest positive integer that can divide X and is other than X itself. Or N is the smallest positive integer that can divide X, or N is the largest positive integer that can divide X and is other than X itself.

[0593] Exemplarily, assuming that X RBs are allocated in a slot, then for intra-symbol OCC, the OCC length = X x the number of subcarriers in one RB / M. Where M is defined similarly to the value of N described above, and is not described in more detail.

[0594] In some embodiments, the intra-symbol or inter-symbol OCC length is determined by the number of slots occupied by a single TBoMS. For example, for scheme 1 or scheme 2 or using independent intra / inter-symbol OCC scheme, the protocol can implicitly specify that the number of slots occupied by a TBoMS = intra / inter-symbol OCC length.

[0595] In some embodiments, the OCC parameters corresponding to different OCC mechanisms in the OCC mechanism combination are determined based on the same or different manners; wherein the manners include at least one of the following: a first manner, the first manner is a manner of determining the OCC mechanism and / or the OCC sequence length based on the communication protocol rule information; a second manner, the second manner is a manner of determining the OCC mechanism and / or the OCC sequence length based on the configuration information sent by the network device.

[0596] In some embodiments, for the determination of the OCC sequence length, different OCC schemes participating in the OCC scheme combination can employ the same or different determination manners. For example, assuming that the protocol pre-sets scheme 1, one possible example is that the inter-slot OCC multiplexing employs the protocol pre-set manner to determine the OCC sequence length L (corresponding to the first manner), while the intra-symbol OCC spreading employs an explicit parameter configured by RRC signaling to determine the OCC length (corresponding to the second manner).

[0597] In some embodiments, the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on a protocol pre-set rule and / or configuration information sent by a network device.

[0598] In some embodiments, for different terminals, the same OCC mechanism is used, and different OCC sequence lengths are used.

[0609] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each of the OCC mechanism combinations includes at least two OCC mechanisms; OCC sequence length of the OCC mechanisms is one; a plurality of seventeenth mapping relationships between each of the OCC mechanisms, OCC sequences, OCC sequence lengths, and indexes in different OCC mechanism combinations are determined based on the preset rules of the protocol or the configuration information; a first OCC mechanism combination is determined based on fourth information; the fourth information is information received from a network device; at least one of the seventeenth mapping relationships is determined from the plurality of seventeenth mapping relationships based on at least two OCC mechanisms in the first OCC mechanism combination; a sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on first information and the at least one of the seventeenth mapping relationships; the first information is information received from a network device or information determined based on a terminal identifier, and the first information is used to indicate an index.

[0610] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each of the OCC mechanism combinations includes at least two OCC mechanisms; OCC sequence length of the OCC mechanisms is at least two; a plurality of eighteenth mapping relationships between each of the OCC mechanisms, OCC sequences, OCC sequence lengths, and indexes in different OCC mechanism combinations are determined based on the preset rules of the protocol or the configuration information; a first OCC mechanism combination is determined based on fourth information; the fourth information is information received from a network device; OCC sequence length of each OCC mechanism in the first OCC mechanism combination is determined based on a determination manner of the OCC sequence length; at least one of the eighteenth mapping relationships is determined from the plurality of eighteenth mapping relationships based on the OCC sequence length and at least two OCC mechanisms in the first OCC mechanism combination; a sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on first information and the at least one of the eighteenth mapping relationships; the first information is information received from a network device or information determined based on a terminal identifier, and the first information is used to indicate an index.

[0611] In some embodiments, the OCC mechanism combination includes at least two OCC combinations; each of the OCC mechanism combinations includes at least two OCC mechanisms; and determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on the preset protocol rule and / or the configuration information sent by the network device includes: determining a plurality of nineteenth mapping relationships between each OCC mechanism, OCC sequence, OCC sequence length and index in the OCC mechanism combination based on the preset protocol rule or the configuration information; determining a first OCC mechanism combination based on fourth information; wherein the fourth information is information received from the network device; determining the OCC sequence length of each OCC mechanism in the first OCC mechanism combination based on a determination manner of the OCC sequence length; determining at least two of the nineteenth mapping relationships from the plurality of nineteenth mapping relationships based on the OCC sequence length and at least two OCC mechanisms in the first OCC mechanism combination; and determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on first information and the at least two of the nineteenth mapping relationships; wherein the first information is information received from the network device or information determined based on a terminal identifier, and the first information is used to indicate the index.

[0612] In some embodiments, different OCC mechanisms adopt the same sequence type; and determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on the preset protocol rule and / or the configuration information sent by the network device includes: determining a twentieth mapping relationship between an OCC sequence index and an OCC sequence length based on the preset protocol rule or the configuration information for the adopted sequence type; and determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on the preset protocol rule, first information and the twentieth mapping relationship; wherein the first information is information sent by the network device or information determined based on a terminal identifier, and the first information is used to indicate the index.

[0613] In some embodiments, the preset protocol rule is to determine a twenty-first mapping relationship based on the twentieth mapping relationship, an OCC mechanism and an OCC sequence length of the OCC mechanism.

[0614] Exemplarily, the protocol supports multiple OCC mechanism combinations, different OCC mechanism combinations have independent joint tables, and the terminal first needs to determine multiple mapping relationships under different OCC mechanism combinations (mainly considering that different OCC lengths have different mapping relationships). Then determine a unique OCC mechanism combination based on the configuration signaling, and determine the OCC sequence length of each OCC mechanism in the OCC mechanism combination based on the above OCC sequence length determination method, further determine a unique mapping relationship; based on the mapping relationship and the configuration information (index index information), determine the sequence of each OCC scheme of the current terminal.

[0615] Exemplarily, the OCC length of different OCC mechanisms can also be unique, in which case, an OCC mechanism combination has only one mapping relationship table.

[0616] Exemplarily, way one: determine the sequence of each OCC scheme in the OCC scheme combination through the joint indication scheme

[0617] In some embodiments, the protocol presets the OCC sequence joint table of different OCC schemes in the OCC scheme combination. Alternatively, the gNB configures the OCC sequence joint table of different OCC schemes in the OCC scheme combination.

[0618] In some embodiments, it is assumed that intra-symbol OCC and inter-slot OCC are used, and it is further assumed that the intra-symbol OCC length is 4 and the inter-slot OCC length is 2. Then, a possible OCC sequence joint table is shown in Table 6. Further, for a specific terminal, the OCC sequence of different OCC schemes can be determined through the OCC sequence index (corresponding to the first information) carried in the DCI, MAC signaling or RRC signaling sent by the gNB.

[0619] Table 6:

[0620] In some embodiments, for OCC sequence index indication by DCI, or the way of OCC sequence indication, new field (applicable to non-fallback DCI) can be used, or existing field can be used. For the way of using existing field, at least one of the following can be used: at least part of bits of FDRA, TDRA, FH flag, MCS, TPC, antenna port, etc. For example, OCC sequence index of different OCC schemes can be determined implicitly by the antenna port field carried in the DCI.

[0621] In some embodiments, taking Table 7 as an example, the protocol can preset a one-to-one mapping relationship between the DMRS port and the OCC sequence index, for example, DMRS port 0 corresponds to OCC sequence index 0, DMRS port 1 corresponds to OCC sequence index 1, and so on. Further, the terminal can determine the DMRS port through the antenna port field carried in the DCI, and further determine the OCC sequence index it adopts. Finally, the OCC sequences corresponding to the intra-symbol OCC and the inter-slot OCC can be determined. This way can also be applicable to other schemes described below, and details are not described again.

[0622] Table 7:

[0623] In some embodiments, different OCC length combinations can have different OCC sequence combination tables. For example, the protocol can preset to use intra-symbol and inter-slot OCC combination.

[0624] In some embodiments, the OCC length of the two OCC schemes can include at least one of the following: {2, 2}, {4, 2}, {1, 2}, {4, 1}, {2, 1}, etc. Then, different OCC sequence combination tables can be configured or preset for different OCC length combinations.

[0625] In addition, the protocol can preset multiple different OCC scheme combination manners. For different OCC scheme combination manners, there can be different OCC sequence combination tables.

[0626] Exemplarily, the sequence of each OCC scheme in the OCC scheme combination is determined through the joint indication scheme.

[0627] In some embodiments, the protocol presets independent OCC sequence tables for different OCC schemes. Different OCC sequence lengths can have different OCC sequence tables. In addition, the protocol presets certain rules, so that the terminal can determine the mapping relationship between the OCC sequence indication value carried by the DCI and different OCC sequences. Further, for a specific terminal, the OCC sequence index of different OCC schemes can be determined through the indication field carried in the DCI.

[0628] In some embodiments, an example is expanded with intra-symbol OCC length = 4 and inter-slot OCC length = 2. A possible OCC sequence table example is shown in Table 8. It is assumed that the value range of the OCC sequence carried in the DCI for indicating the OCC sequence is 0-7. Then it can have the following mapping relationship with the intra-symbol OCC and the inter-slot OCC sequence: OCC sequence index in DCI = floor (inter-slot OCC sequence index) x intra-symbol OCC length + intra-symbol OCC sequence index. Wherein, the intra-symbol OCC length is determined by any embodiment of the present disclosure.

[0629] Table 8:

[0630] Table 9:

[0631] Exemplarily, different OCC mechanisms have one or more (depending on whether the occ length is the only value preset by the protocol) independent OCC sequence table. The terminal first determines the OCC sequence table corresponding to each occ length (in the case of more than one length) of each OCC mechanism based on the protocol, then determines the OCC scheme (assuming M schemes) and the corresponding occ length under the OCC mechanism combination, so that M tables can be determined; then, based on the M indexes indicated by the gNB, the OCC sequence corresponding to each OCC scheme in the M OCC schemes is determined.

[0632] Exemplarily, there are at least two independent tables (of course, there can be three or more, and different OCC schemes correspond to different tables), and the terminal first determines N independent tables, then determines which M of the N tables to use based on the gNB configuration / configuration information, and further determines the OCC sequence of the current OCC scheme based on the configuration information of the table index. The M tables correspond to M configuration information.

[0633] In some embodiments, for a certain OCC scheme combination scheme, one possible way is that different OCC schemes adopt the same sequence type, for example, for scheme 2, both inter-symbol & inter-slot OCC adopt Walsh sequence. Then, for Walsh sequence, the protocol predefines OCC sequence table of different OCC sequence length (corresponding to the tenth mapping relationship). In addition, the protocol predefines the mapping manner between the OCC sequence of different OCC schemes and the OCC sequence in the table (corresponding to the eleventh mapping relationship). Further, for a certain terminal, the OCC sequence index of different OCC schemes is determined by a row in the table indicated by DCI. Take inter-symbol OCC length = 2, inter-slot OCC length = 2 as an example for expansion, the OCC sequence table of length 4 is shown in Table 10. One possible preset rule is as follows: the first two bits of a length 4 sequence are inter-symbol OCC sequence, based on OCC Seq of length 4 and the first two bits of OCC sequence value, the OCC Seq value of inter-slot can be determined. For example, based on the above rule, Table 10 can be converted into Table 11.

[0634] Table 10:

[0635] Table 11:

[0636] In some embodiments, the terminal receives the fifth information sent by the network device; wherein the fifth information is used to indicate the OCC sequence corresponding to at least one of the OCC mechanisms.

[0637] In some embodiments: the sequence of each OCC scheme in the OCC scheme combination is determined by the independent parameter indicated by the gNB.

[0638] In some embodiments, the configuration or indication can be performed by RRC signaling, MAC signaling or DCI, and the specific indication manner is the same as that in Mode 1. The protocol is preset or gNB configures an OCC sequence table. Different OCC sequence tables are used for different OCC sequences. For a specific terminal, the index of the OCC sequence table is indicated by the same field or different bits of different fields to determine the sequence of different OCC schemes.

[0639] In some embodiments, the sequence of each OCC scheme is determined in an implicit manner.

[0640] For example, the OCC sequence index can be determined by terminal identification (UE ID), such as cell radio network temporary identifier (C-RNTI). The gNB and the terminal determine the OCC sequence index based on the same criteria.

[0641] For example, assuming that intra-symbol and inter-slot OCC are used, the intra-symbol OCC length is 2, and the inter-slot OCC length is 2, then mod(C-RNTI, 4) = 0 / 1 / 2 / 3, 0 / 1 / 2 / 3 are respectively associated with (intra-symbol OCC S#0, inter-slot OCC S#0), (intra-symbol OCC S#1, inter-slot OCC S#0), (intra-symbol OCC S#0, inter-slot OCC S#1), (intra-symbol OCC S#1, inter-slot OCC S#1). Alternatively, 0 / 1 / 2 / 3 can also be the index of the table described in Mode 1 / 2. Alternatively, it is the OCC sequence index on the left side of the formula described in Mode 1-2. When performing OCC scheduling, the gNB schedules C-RNTI mod(C-RNTI, 4) = 0 / 1 / 2 / 3 on the same block of time-frequency domain resources for OCC multiplexing. The terminal and the base station respectively determine the occ sequence based on the same rule.

[0642] In addition, in the above manner, if a new field is added or an existing field is used to indicate the OCC sequence index, the number of bits used by the OCC sequence index is related to the OCC length of different OCC schemes in the OCC scheme combination.

[0643] In some embodiments, for the determination of the OCC sequence index, different OCC schemes participating in the OCC scheme combination can use the same or different determination methods. For example, assuming that scheme 1 is used, the inter-slot OCC multiplexing uses the third implicit method to determine the OCC sequence, and for the intra-symbol OCC spreading, the gNB explicitly indicates the method for determining the OCC sequence.

[0644] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0645] In some embodiments, the term "send" can be mutually replaced with the terms "transmit", "report", "transport", and the like.

[0646] The information indication method related to the embodiments of the present disclosure can include at least one of steps S2101 to S2102. For example, step S2101 can be implemented as an independent embodiment, and step S2102 can be implemented as an independent embodiment. For example, step S2101 in combination with step S2102 can be implemented as an independent embodiment, but is not limited thereto. It should be noted that each step can be independently implemented, or in the case of no contradiction, the order can be arbitrarily exchanged and freely combined for implementation.
