[0372] In some embodiments, a scheme 1 is provided, which combines the intra-symbol with the inter-slot mechanism:

[0373] In some embodiments, 1-1: Consider the intra-symbol OCC spreading combination of M UEs and the 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 among M*N UEs can be achieved.

[0374] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in one block X = the total number of resource elements (REs) on the same symbol / M), and OCC sequence covering.

[0375] S2: Generate the symbol to be transmitted in the first slot based on S1, and perform spreading in N-1 slots; or, perform rate-matching in N slots based on the same redundant version and the same starting symbol position, while generating the transmission symbols for N slots based on S1. Therefore, the same symbols are carried in N slots. Further, each value of the currently user-determined OCC sequence of length N is covered onto each spreading slot.

[0376] S3: Assuming a time slot contains N slots, and the number of repetitions K indicated by gNB is greater than N, then there are K / N time slots. RV cycles can be performed between the K / N time slots, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols for each time slot are generated based on S1 and S2.

[0377] Assuming the number of repetitions is 8, M=4, N=2, and the number of RBs is 1, one possible diagram is as follows: Figure 1b As shown.

[0378] In some embodiments, a scheme 1 is provided, which combines the intra-symbol with the inter-slot mechanism:

[0379] In some embodiments, 1-2: Consider the intra-symbol OCC spread spectrum combination of M UEs and the 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), thereby achieving a maximum of M*N UE OCC multiplexing. Based on this, consider combining it with the TBoMS mechanism to enhance the data transmission performance of a single link. Consider the following two different schemes:

[0380] 1-2-1: First, perform inter-slot OCC spreading, followed by the transmission of subsequent time-slot multiplexed transport blocks (TBoMS). Assume that TBoMS occupies D slots (where D is the number of slots occupied by a single modulation symbol transmission, excluding the additional N-1 slots occupied by inter-slot OCC multiplexing within a time slot, excluding the first slot). Optionally, repetition can be performed finally based on RV cycling.

[0381] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in one block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0382] S2: Generate the symbol to be transmitted in the first slot based on S1, and perform spreading in N-1 slots; or, perform rate-matching in N slots based on the same redundant version and the same starting symbol position, while generating the transmission symbols for N slots based on S1. Therefore, the same symbols are carried in N slots. Further, each value of the currently user-determined OCC sequence of length N is covered into each spreading slot.

[0383] S3: Increment the end bit position obtained from S1 / 2 by 1 to get the start bit position. Perform rate-matching based on the start bit position and the number of bits that can be carried in the (N+i)th slot (i = 1, 2, ..., N) (or, the number of available resources and modulation order, etc.). For the remaining processing in the (N+i)th slot, follow S1 and S2.

[0384] 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 method as S3 is used to determine the starting bit position of rate-matching.

[0385] S5:

[0386] S5-1: Assuming a time slot contains N*D slots, optionally, the number of repetitions K indicated by the gNB is greater than N, then there are K / N time slots. RV cycling can be performed between the K / N time slots, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols are generated for each time slot based on S1 to S4.

[0387] S5-2: Alternatively, the number of repetitions indicated by the gNB is K=N. In other words, the terminal does not expect the number of repetitions indicated by the gNB to be unequal to the inter-slot OCC sequence length.

[0388] S5-3: Alternatively, the number of repetitions indicated by the gNB is K = N*D. In other words, the terminal does not expect the number of repetitions indicated by the gNB to exceed the product of the number of slots occupied by one TBoMS transmission and the length of the inter-slot OCC.

[0389] Based on S5-1, assuming the number of repetitions is 4, M=4, N=2 (inter-slot OCC length), the number of RBs is 1, and the number of slots D occupied by TBoMS transmission is 2, then a possible diagram is as follows: Figure 1c As shown.

[0390] In some embodiments, a scheme 1 is provided: combining intra-symbol with inter-slot mechanism:

[0391] In some embodiments, 1-2: Consider the intra-symbol OCC spread spectrum combination of M UEs and the 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), thereby achieving a maximum of M*N UE OCC multiplexing. Based on this, consider combining it with the TBoMS mechanism to enhance the data transmission performance of a single link. Consider the following two different schemes:

[0392] 1-2-2: Perform TBoMS first, followed by inter-slot OCC spreading. Assume TBoMS occupies D slots. Optionally, repetition can be performed last.

[0393] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in one block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0394] S2: Generate the symbol for the first slot based on S1; in addition, determine the end bit position when rate-matching is performed on the first slot + 1 as the start bit position for the next slot, and perform rate-matching for the next slot based on the start 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 for the next slot based on S1.

[0395] S3: Based on S2, determine the transmission symbols on D slots. It can be imagined that the position of the start bit carried in each slot is the position of the end bit in the previous slot + 1.

[0396] S4: Determine that each D slots constitute a slot segment. Generate the symbols to be transmitted on the first slot segment based on S1 to S3, and perform spreading on the N-1 slot segments; alternatively, perform rate-matching on the N slot segments based on the same redundant version, and simultaneously generate the symbols to be transmitted on the N slot segments based on S1 to S3. Based on this, the N slot segments carry the same transmission symbols. Further, each value of the currently user-determined OCC sequence of length N is covered onto each spreading slot segment.

[0397] S5:

[0398] S5-1: Assuming a block contains N*D slots, optionally, if the repetition count K indicated by the gNB is greater than N, then there are K / N time slots. RV cycling can be performed between the K / N blocks, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols for each block are generated based on S1 to S4.

[0399] S5-2: Alternatively, the number of repetitions indicated by the gNB is K=N. In other words, the terminal does not expect the number of repetitions indicated by the gNB to be unequal to the inter-slot OCC sequence length.

[0400] S5-3: Alternatively, the number of repetitions indicated by the gNB is K = N*D. In other words, the terminal does not expect the number of repetitions indicated by the gNB to exceed the product of the number of slots occupied by one TBoMS transmission and the length of the inter-slot OCC.

[0401] Based on S5-1, assuming the number of repetitions is 4, M=4, N=2 (inter-slot OCC length), the number of RBs is 1, and the number of slots D occupied by TBoMS transmission is 2, then a possible diagram is shown in 1d.

[0402] In some embodiments, a second approach is provided: combining inter-symbol OCC spreading with an inter-slot OCC multiplexing mechanism.

[0403] In some embodiments, the inter-symbol OCC spread spectrum combination of M UEs and the inter-slot OCC multiplexing of N UEs are considered, 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).

[0404] S1: Within a slot, the terminal performs rate-matching, DFT symbol(s) spreading, and OCC sequence covering based on OCC length = M. DFT symbol spreading can be single-symbol based spreading or symbol-block based spreading. Similarly, OCC sequence covering can be single-symbol based OCC sequence covering (one OCC sequence value covers a corresponding symbol) or symbol-block based OCC covering (one OCC sequence value covers a symbol-block). Taking a slot with 6 symbols used for PUSCH transmission and an OCC length as an example, the diagrams for single-symbol based spreading and symbol-block based spreading are shown in Figure 1e.

[0405] S2: Generate the symbol to be transmitted on the first slot based on S1, and perform spreading on N-1 slots; or, perform rate-matching on N slots based on the same redundant version, and simultaneously generate 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 currently user-determined OCCsequence of length N is covered onto each spreading slot.

[0406] S3: Assuming a time slot contains N slots, and the number of repetitions K indicated by the gNB is greater than N, then there are K / N time slots. RV cycling can be performed between the K / N time slots, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols are generated for each time slot based on S1 and S2.

[0407] Assuming the number of repetitions is 4, M = 2 (inter-symbol OCC length), N = 2 (inter-slot OCC length), and 6 symbols are used to carry data in a slot (this is just an example, excluding DMRS symbols), a possible illustration of single-symbol based spreading is shown in 1f.

[0408] In some embodiments, a second approach is provided: combining inter-symbol OCC spreading with an inter-slot OCC multiplexing mechanism.

[0409] In some embodiments, the inter-symbol OCC spread spectrum combination of M UEs and the inter-slot OCC multiplexing of N UEs are considered, 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). Based on this, a combination with the TBoMS mechanism is considered to enhance the data transmission performance of a single link. The following two different schemes are considered:

[0410] 1-2-1: First, perform inter-slot OCC spreading, followed by symbol determination and transmission based on TBoMS PUSCH. Assume that TBoMS occupies D slots. Optionally, repetition can be performed last.

[0411] S1: Within a slot, the terminal performs the following based on OCC length = M: rate-matching, DFT symbol(s) spreading, and OCC sequence covering. DFT symbol spreading can be single-symbol based spreading or symbol-block based spreading. Similarly, OCC sequence covering can be single-symbol based OCC sequence covering (one OCC sequence value covers a corresponding symbol) or symbol-block based OCC covering (one OCC sequence value covers a symbol-block).

[0412] S2: Generate the symbol to be transmitted on the first slot based on S1, and perform spreading on N-1 slots; or, perform rate-matching on N slots based on the same redundant version, and simultaneously generate 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 currently user-determined OCCsequence of length N is covered onto each spreading slot.

[0413] S3: Increment the end bit position obtained from S1 / 2 by 1 to get the start bit position. Perform rate-matching based on the start bit position and the number of bits that can be carried in the (N+i)th slot (i = 1, 2, ..., N) (or the number of available resources and modulation order, etc.). For the remaining processing flow of the data symbols in the (N+i)th slot, follow S1 and S2.

[0414] 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 starting bit position of rate-matching is determined in the same way as in S3.

[0415] S5:

[0416] S5-1: Assuming a time slot contains N*D slots, optionally, the number of repetitions K indicated by the gNB is greater than N, then there are K / N time slots. RV cycling can be performed between the K / N time slots, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols are generated for each time slot based on S1 to S4.

[0417] S5-2: Alternatively, the number of repetitions indicated by the gNB is K=N. In other words, the terminal does not expect the number of repetitions indicated by the gNB to be unequal to the inter-slot OCC sequence length.

[0418] S5-3: Alternatively, the number of repetitions indicated by the gNB is K = N*D. In other words, the terminal does not expect the number of repetitions indicated by the gNB to exceed the product of the number of slots occupied by one TBoMS transmission and the length of the inter-slot OCC.

[0419] Based on S5-1, assuming the number of repetitions is 4, M = 2 (inter-symbol OCC length), N = 2 (inter-slot OCC length), the number of slots for TBoMS PUSCH = 2 (not considering the slots occupied by inter-slot OCC), and 6 symbols used to carry data in a slot (only as an example, not considering DMRS symbols), taking single-symbol based spreading as an example, a possible diagram is shown in 1g.

[0420] In some embodiments, a second approach is provided, which combines inter-symbol OCC spreading with an inter-slot OCC multiplexing mechanism:

[0421] Consider the inter-symbol OCC spread spectrum combination of M UEs and the 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). Based on this, consider combining it with the TBoMS mechanism to enhance the data transmission performance of a single link. Consider the following two different schemes:

[0422] 1-2-2: First, the symbol determination and transmission of the TBoMS PUSCH are performed, followed by the determination of the time-domain resource location of the inter-slot OCC. Assume that the number of slots occupied by TBoMS is D. Optionally, repetition is performed last.

[0423] S1: Within a slot, the terminal performs the following based on OCC length = M: rate-matching, DFT symbol(s) spreading, and OCC sequence covering. DFT symbol spreading can be single-symbol based spreading or symbol-block based spreading. Similarly, OCC sequence covering can be single-symbol based OCC sequence covering (one OCC sequence value covers a corresponding symbol) or symbol-block based OCC covering (one OCC sequence value covers a symbol-block).

[0424] S2: Generate the symbol for the first slot based on S1; furthermore, determine the end bit position of the first slot when performing rate-matching + 1 as the start bit position for the next slot, and perform rate-matching for the next slot based on the start bit position and the number of bits that the next slot can carry (or the number of available resources and the modulation order, etc.). Simultaneously, generate the transmission symbol for the next slot based on S1.

[0425] S3: Based on S2, determine the transmission symbols on D slots. It can be assumed that the position of the start bit carried in each slot is the position of the end bit in the previous slot + 1.

[0426] S4: Determine that each D slots constitute a slot segment. Generate the symbols to be transmitted on the first slot segment based on S1 to S3, and perform spreading on the N-1 slot segments; alternatively, perform rate-matching on the N slot segments based on the same redundant version, and simultaneously generate the symbols to be transmitted on the N slot segments based on S1 to S3. Based on this, the N slot segments carry the same transmission symbols. Further, each value of the currently user-determined OCC sequence of length N is covered onto each spreading slot segment.

[0427] S5:

[0428] S5-1: Assuming a block contains N*D slots, optionally, if the repetition count K indicated by the gNB is greater than N, then there are K / N time slots. RV cycling can be performed between the K / N blocks, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols for each block are generated based on S1 to S4.

[0429] S5-2: Alternatively, the number of repetitions indicated by the gNB is K=N. In other words, the terminal does not expect the number of repetitions indicated by the gNB to be unequal to the inter-slot OCC sequence length.

[0430] S5-3: Alternatively, the number of repetitions indicated by the gNB is K = N*D. In other words, the terminal does not expect the number of repetitions indicated by the gNB to exceed the product of the number of slots occupied by one TBoMS transmission and the length of the inter-slot OCC.

[0431] Based on S5-1, assuming the number of repetitions is 4, M = 2 (inter-symbol OCC length), N = 2 (inter-slot OCC length), the number of slots for TBoMS PUSCH = 2 (not considering the slots occupied by inter-slot OCC), and 6 symbols used to carry data in a slot (only as an example, not considering DMRS symbols), taking single-symbol based spreading as an example, a possible diagram is shown in 1h.

[0432] In some embodiments, a scheme 3 is provided, which combines intra-symbol OCC spreading with inter-symbol OCC multiplexing mechanism:

[0433] In some embodiments, the intra-symbol OCC spread spectrum combination of M UEs and the inter-symbol OCC multiplexing of N UEs are considered, 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).

[0434] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in a block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0435] S2: Based on S1, generate the symbol to be transmitted on the first symbol and spread it across N-1 symbols; or, on a symbol block basis, generate the symbol to be transmitted on the first symbol block (assuming a symbol block contains P symbols) and spread it across N-1 symbol blocks. Based on this, the same symbol is carried across N symbols or N symbol blocks. Further, each value of the currently user-defined OCC sequence of length N is covered onto each spreading symbol or symbol-block.

[0436] S3: Assuming the number of repetitions indicated by the gNB is K, then RV cycling can be performed between the K repetitions. The RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. The data symbols carried in each time slot are generated based on S1 and S2.

[0437] Assuming the number of repetitions is 4, M = 4 (intra-symbol OCC length), N = 2 (inter-symbol OCC length), the number of RBs = 1, and the number of symbols used to carry data in a slot is 6, with spreading performed in units of single symbols, then a possible diagram is shown in 1i.

[0438] In some embodiments, a scheme 3 is provided, which combines intra-symbol OCC spreading with inter-symbol OCC multiplexing mechanism:

[0439] In some embodiments, the intra-symbol OCC spreading combinating of M UEs with the inter-symbol OCC multiplexing of NUEs is considered, 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). Based on this, a combination with the TBoMS mechanism is considered to enhance the data transmission performance of a single link. The following transmission scheme is considered: first, the intra-transmission symbols of a slot are determined, then symbol determination and transmission are performed based on TBoMS PUSCH. Assume that the number of slots occupied by TBoMS is D. Finally, repetition is performed.

[0440] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in one block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0441] S2: Based on S1, generate the symbol to be transmitted on the first symbol and spread it across N-1 symbols; or, on a symbol block basis, generate the symbol to be transmitted on the first symbol block (assuming a symbol block contains P symbols) and spread it across N-1 symbol blocks. Based on this, the same symbol is carried across N symbols or N symbol blocks. Further, each value of the currently user-defined OCC sequence of length N is covered onto each spreading symbol or symbol-block.

[0442] S3: Generate the symbol for the first slot based on S1 / S2; in addition, determine the end bit position when rate-matching is performed on the first slot + 1 as the start bit position for the next slot, and perform rate-matching for the next slot based on the start bit position and the number of bits that can be carried in the next slot (or the number of available resources and the modulation order, etc.). At the same time, generate the transmission symbol for the next slot based on S1.

[0443] S4: Based on S3, determine the transmission symbols on D slots. It can be imagined that the position of the start bit carried in each slot is the position of the end bit in the previous slot + 1.

[0444] S5: Each D slots constitutes a slot segment. Assuming the repetition count indicated by the gNB is K, then RV cycling can be performed between K repetitions. The RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Each repetition occupies one time slot. The data symbols carried by each time slot are generated based on S1 to S4. The starting slots of different time slots use different starting coding bits when performing rate matching, i.e., different redundancy versions. Different slots within the same time slot also use different starting bits. The specific method for determining the starting bits is shown in S4.

[0445] Assuming the number of repetitions 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 single TBoMS = 2, and the number of symbols used to carry data in one slot is 6, with spreading performed in units of single symbols, then a possible diagram is shown in Figure 1j.

[0446] In some embodiments, a scheme 4 is provided, which combines intra-symbol, inter-symbol, and inter-slot mechanisms:

[0447] In some embodiments, consider intra-symbol OCC spreading of OCC length M (assuming OCC sequence is referred to by Seq#(1,X)), inter-symbol OCC multiplexing of OCC length N (assuming OCC sequence is referred to by Seq#(2,X)), and inter-slot OCC multiplexing of OCC length L (assuming OCC sequence is referred to by Seq#(3,X)).

[0448] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in one block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0449] S2: Based on S1, generate the first symbol to be transmitted on the symbol, and spread it across N-1 symbols; or, on a symbol block basis, generate the first symbol to be transmitted on the symbol block (assuming a symbol block contains P symbols), and spread it across N-1 symbol blocks. Based on this, the same symbols are carried across N symbols or N symbol blocks. Further, each value of the currently user-determined OCC sequence of length N is covered onto each spreading symbol or symbol-block. In the same way, the generation of symbols to be transmitted on the remaining time-domain resources is performed until the generation of symbols to be transmitted on all time-domain resources in a slot is completed.

[0450] S3: Generate the symbol to be transmitted in the first slot based on S1 / 2, and perform spreading in L-1 slots; or, perform rate-matching on L slots based on the same redundant version, and simultaneously generate the transmission symbols for L slots based on S1. Based on this, the same symbols are carried in L slots. Further, each value of the currently user-determined OCCsequence of length L is covered to each spreading slot.

[0451] S4: Assuming a time slot contains L slots, and the number of repetitions K indicated by the gNB is greater than N, then there are K / L time slots. RV cycling can be performed between the K / L time slots, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols are generated for each time slot based on S1 to S3.

[0452] Assuming there are 8 repetitions, M = 2 (intra-symbol OCC length), N = 2 (inter-symbol OCC length), L = 2 (inter-slot OCC length), 1 RB, and 6 symbols used to carry data in a slot, with spreading performed in units of single symbols, then one possible diagram is shown in 1k.

[0453] In some embodiments, a scheme 4 is provided, which combines intra-symbol, inter-symbol, and inter-slot mechanisms:

[0454] In some embodiments, consider intra-symbol OCC spreading of OCC length M (assuming OCC sequence is referred to by Seq#(1,X)), inter-symbol OCC multiplexing of OCC length N (assuming OCC sequence is referred to by Seq#(2,X)), and inter-slot OCC multiplexing of OCC length L (assuming OCC sequence is referred to by Seq#(3,X)). Based on this, consider combining it with the TBoMS mechanism to enhance the data transmission performance of a single link. Consider the following two different schemes:

[0455] First, perform inter-slot OCC multiplexing, then perform TBoMS. Finally, optionally, perform repetition.

[0456] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in a block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0457] S2: Based on S1, generate the first symbol to be transmitted on the symbol, and spread it across N-1 symbols; or, on a symbol block basis, generate the first symbol to be transmitted on the symbol block (assuming a symbol block contains P symbols), and spread it across N-1 symbol blocks. Based on this, the same symbols are carried across N symbols or N symbol blocks. Further, each value of the currently user-determined OCC sequence of length N is covered onto each spreading symbol or symbol-block. In the same way, the generation of symbols to be transmitted on the remaining time-domain resources is performed until the generation of symbols to be transmitted on all time-domain resources in a slot is completed.

[0458] S3: Generate the symbol to be transmitted in the first slot based on S1 / 2, and perform spreading in L-1 slots; or, perform rate-matching on L slots based on the same redundant version, and simultaneously generate the transmission symbols for L slots based on S1. Based on this, the same symbols are carried in L slots. Further, each value of the currently user-determined OCCsequence of length L is covered to each spreading slot.

[0459] S4: Increment the end bit position obtained from S1 / 2 by 1 to get the start bit position. Perform rate-matching based on the start bit position and the number of bits that can be carried in the (L+i)th slot (i = 1, 2, ..., L) (or, the number of available resources and modulation order, etc.). For the remaining processing flow of the data symbols in the (L+i)th slot, follow S1 and S2.

[0460] S5: Based on S1 / 2 / 3 / 4, complete all symbol processing and transmission on D*L slots. 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 in S4.

[0461] S6:

[0462] S6-1: Assuming a time slot contains L*D slots, optionally, if the repetition count K indicated by the gNB is greater than L, then there are K / L time slots. RV cycling can be performed between the K / L time slots, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols are generated for each time slot based on S1 to S4.

[0463] S6-2: Alternatively, the number of repetitions indicated by the gNB is K = L. In other words, the terminal does not expect the number of repetitions indicated by the gNB to be unequal to the inter-slot OCC sequence length.

[0464] S6-3: Alternatively, the number of repetitions indicated by the gNB is K = L*D. In other words, the terminal does not expect the number of repetitions indicated by the gNB to exceed the product of the number of slots occupied by one TBoMS transmission and the length of the inter-slot OCC.

[0465] Based on S6-1, assuming the number of repetitions is 4, M = 2 (inter-symbol OCC length), N = 2 (inter-slot OCC length), the number of slots for TBoMS PUSCH = 2 (not considering the slots occupied by inter-slot OCC), the number of symbols used to carry data in a slot is 6 (only as an example, not considering DMRS symbols), L = 2, taking single-symbol based spreading as an example, a possible diagram is shown in 1l.

[0466] In some embodiments, a scheme 4 is provided, considering intra-symbol OCC spreading of OCC length M (assuming OCC sequence is referred to by Seq#(1,X)), inter-symbol OCC multiplexing of OCC length N (assuming OCC sequence is referred to by Seq#(2,X)), and inter-slot OCC multiplexing of OCC length L (assuming OCC sequence is referred to by Seq#(3,X)). Based on this, a combination with the TBoMS mechanism is considered to enhance the data transmission performance of a single link. The following two different schemes are considered:

[0467] 4-2: First, determine and transmit the symbol for the TBoMS PUSCH, then determine the time-domain resource location of the inter-slot OCC, assuming that the number of slots occupied by TBoMS is D. Optionally, repetition can be performed last.

[0468] S1: Within a slot, the terminal first performs the following based on OCC length = M: rate-matching, block-wise modulation symbol spreading (the number of symbols in one block X = the total number of REs on the same symbol / M), and OCC sequence covering.

[0469] S2: Based on S1, generate the first symbol to be transmitted on the symbol, and spread it across N-1 symbols; or, on a symbol block basis, generate the first symbol to be transmitted on the symbol block (assuming a symbol block contains P symbols), and spread it across N-1 symbol blocks. Based on this, the same symbols are carried across N symbols or N symbol blocks. Further, each value in the currently user-determined OCC sequence of length N is covered onto each spreading symbol or symbol-block. In the same way, the generation of symbols to be transmitted on the remaining time-domain resources is performed until the generation of symbols to be transmitted on all time-domain resources in a slot is completed.

[0470] S3: Generate the symbol for the first slot based on S1; in addition, determine the end bit position of the first slot when performing rate-matching + 1 as the start bit position for the next slot, and perform rate-matching for the next slot based on the start bit position and the number of bits that can be carried in the next slot (or the number of available resources and the modulation order, etc.). At the same time, generate the transmission symbol for the next slot based on S1.

[0471] S4: Based on S2, determine the transmission symbols on D slots. It can be imagined that the position of the start bit carried in each slot is the position of the end bit in the previous slot + 1.

[0472] S5: Determine that each D slots constitute a slot segment. Generate the symbols to be transmitted on the first slot segment based on S1 to S3, and perform spreading on L-1 slot segments; alternatively, perform rate-matching on L slot segments based on the same redundant version, and simultaneously generate the symbols to be transmitted on L slot segments based on S1 to S3. Based on this, the same transmission symbols are carried on N slot segments. Further, each value of the currently user-determined OCC sequence of length N is covered onto each spreading slot segment.

[0473] S6:

[0474] S6-1: Assuming a block contains L*D slots, optionally, if the repetition count K indicated by the gNB is greater than L, then there are K / L time slots. RV cycling can be performed between the K / L blocks, and the RV sequence can be {0,2,0,2}, {0,3,0,3}, or {0,2,3,1}. Data symbols for each block are generated based on S1 to S4.

[0475] S6-2: Alternatively, the number of repetitions indicated by the gNB is K = L. In other words, the terminal does not expect the number of repetitions indicated by the gNB to be unequal to the inter-slot OCC sequence length.

[0476] S6-3: Alternatively, the number of repetitions indicated by the gNB is K = L*D. In other words, the terminal does not expect the number of repetitions indicated by the gNB to exceed the product of the number of slots occupied by one TBoMS transmission and the length of the inter-slot OCC.

[0477] Based on S6-1, assuming the number of repetitions 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 used to carry data in a slot is 6, spreading is done in units of single symbols, and D = 2, then a possible diagram is shown as 1m.

[0478] In some embodiments, considering the large coverage area of ​​non-terrestrial network (NTN) cells, 8-UE multiplexing is not entirely excluded from current considerations to effectively improve system capacity / throughput. For PUSCH capacity enhancement, one feasible solution is to perform OCC based on PUSCH repetition type A, i.e., introducing inter-slot based OCC multiplexing. However, a drawback of this solution is that, considering the impact of channel time-varying characteristics, the link performance of a single user is very poor when multiplexing 8 UEs. Alternatively, pre-DFT based OCC spreading or inter-symbol OCC spreading can be considered. However, a limitation of these two solutions is the significant impact and constraints on resource allocation. Therefore, a multi-OCC scheme combination can be considered to support multiplexing for more users. Based on this, how to configure and indicate OCC multiplexing under the combination mechanism is a matter that needs to be considered.

[0504] It should be noted that configuration information may be optional. For example, when the mapping relationship is determined based on preset rules of the protocol, configuration information is not required.

[0505] In some embodiments, the network device sends first information to the terminal, the first information being used to indicate an index.

[0506] In some embodiments, the network device sends second information to the terminal, the second information being used to determine a mapping relationship corresponding to an OCC mechanism combination.

[0507] In some embodiments, the network device sends third information to the terminal, the third information being used to indicate the length of the OCC sequence corresponding to at least one OCC mechanism.

[0508] In some embodiments, the network device sends fourth information to the terminal, the fourth information being used to determine a first OCC mechanism combination.

[0509] In some embodiments, the network device sends a fifth message to the terminal, the fifth message being used to indicate an OCC sequence corresponding to at least one of the OCC mechanisms.

[0510] Step S2102: The terminal determines the OCC parameters corresponding to the orthogonal overlay code OCC mechanism.

[0511] In some embodiments, the terminal determines the OCC parameters corresponding to the OCC mechanism in the OCC mechanism scheme combination; wherein the OCC mechanism combination includes at least two OCC mechanisms.

[0512] In some embodiments, the OCC mechanism includes at least one of the following:

[0513] Intra-symbol OCC mechanism;

[0514] Inter-symbol OCC mechanism;

[0515] Inter-slot OCC mechanism.

[0516] In some embodiments, the OCC parameter is a parameter of an OCC sequence, and the parameter of the OCC sequence includes at least one of the following:

[0517] OCC sequence length;

[0518] OCC sequence;

[0519] The OCC sequence index is used to indicate OCC sequences.

[0520] In some embodiments, the OCC sequence includes at least one of the following:

[0521] Walsh sequences;

[0522] Hadamard sequence;

[0523] Discrete Fourier Transform (DFT) sequence.

[0524] In some embodiments, different OCC mechanisms employ independent OCC sequences.

[0525] In some embodiments, for a given time-frequency domain resource, 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, where M, N, and L are positive integers.

[0526] For example, different OCC schemes have corresponding OCC sequence lengths. Assuming that at least one of intra-symbol OCC (assuming OCC length M), inter-symbol OCC (assuming OCC length N), and inter-slot OCC (assuming OCC length L) is supported or configured, then for a given time-frequency domain resource, the maximum number of supported multiplexed users and the above three parameters satisfy the following constraint relationship: Maximum number of UEs = M × N × L, where M, N, and L are positive integers. When at least one of the parameters M, N, and L is 1, it indicates that the corresponding OCC scheme is not supported or is not enabled.

[0527] In some embodiments, the OCC sequence length corresponding to the OCC mechanism is determined based on protocol preset rules and / or configuration information sent by network devices.

[0528] In some embodiments, the configuration information may be configuration information or parameters sent by the network device, and no limitation is made here.

[0529] In some embodiments, the length of the OCC sequence corresponding to the OCC mechanism is determined based on a protocol preset method or a protocol preset value.

[0530] For example, the OCC length can be determined by a preset method or a preset value in the protocol. For instance, in response to the terminal performing inter-slot OCC multiplexing, the OCC sequence length L is fixed at 2.

[0531] In some embodiments, the second OCC sequence length corresponding to the second OCC mechanism in the OCC mechanism combination is determined based on the protocol preset rules, the maximum number of reused users, and the first OCC sequence length of at least one first OCC mechanism.

[0532] In some embodiments, at least one of the maximum number of reused users and the length of the first OCC sequence of at least one first OCC mechanism is determined based on the configuration information.

[0533] In some embodiments, at least one of the maximum number of reused users and the length of the first OCC sequence of at least one first OCC mechanism is determined based on the protocol preset rules.

[0534] In some embodiments, the second OCC sequence length is determined by pre-defined rules in the protocol, the maximum number of reused users, and at least one first OCC sequence length. Different schemes from the aforementioned schemes (Scheme 1, Scheme 2, Scheme 3, Scheme 4) are described separately. The maximum number of reused users and at least one first OCC sequence length can be determined through network configuration or indication parameters (i.e., corresponding configuration information), or through a pre-defined method in the protocol. The methods for determining different first OCC sequence lengths can be different.

[0535] For example, in 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 by network configuration. Furthermore, the maximum number of multiplexed users can be determined by network configuration and / or indication parameters (i.e., corresponding configuration information). Based on this, the intra-symbol OCC length M can be determined by protocol preset rules, for example, M = U / L.

[0536] For example, in 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 by network configuration. Furthermore, the maximum number of multiplexed users can be determined by network configuration and / or indication parameters (i.e., corresponding configuration information). Based on this, the inter-symbol OCC length N can be determined by protocol preset rules, for example, N = U / L.

[0537] For example, in 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 number of multiplexed users are determined through network configuration or indication parameters (i.e., corresponding configuration information). Based on this, the intra-symbol OCC length M can be determined through protocol preset rules, for example, M = U / N.

[0538] For example, in scheme 4, the terminal determines to perform intra-symbol, inter-symbol, and inter-slot combining OCC multiplexing. For instance, the maximum number of multiplexed users U and the intra-symbol OCC sequence length M are determined by the gNB configuration parameters, 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 the protocol preset rules, for example, N = (U / M) / L.

[0539] In some embodiments, the determination of the length of the first OCC sequence is independent; it may be the same or different.

[0540] In some embodiments, a first mapping relationship between an index and the OCC sequence lengths of at least two OCC mechanisms is determined based on the protocol preset rules or the configuration information; based on the first information and the first mapping relationship, the OCC sequence lengths corresponding to at least two of the OCC mechanisms in the OCC mechanism combination are determined; wherein, the first information is information received from the network device, and the first information is used to indicate the index.

[0541] The following is an explanation using Example 1:

[0542] In some embodiments, Scheme 1 described above is used as an example (this is just one example; other schemes, such as Scheme 2, Scheme 3, or Scheme 4, are also possible). Assume the protocol pre-supports the OCC scheme combination mechanism described in Scheme 1. Then, the protocol can pre-define a sequence length combination table for different OCC schemes under this combination mechanism (i.e., determine the first mapping relationship based on the protocol's pre-defined rules).

[0543] 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., an index is indicated by first information, the index corresponding to a row in the table).

[0544] In some embodiments, the gNB can be configured or instructed (i.e., send the first information through the above messages) via Radio Resource Control (RRC), Media Access Control (MAC) Control Element (CE), or Downlink Control Information (DCI).

[0545] In some embodiments, if configuration or indication is made via a MAC CE, it can be a newly added MAC CE (using a new logical channel identifier (LCID) or a reused existing MAC CE), or it can be indicated via a reserved field in the MAC Service Data Unit (SDU) or the MAC subheader of the CE.

[0546] In some embodiments, if indication is given via DCI, existing fields can be reused or new fields can be added.

[0547] In some embodiments, the reuse of existing fields includes at least a portion of bits from fields such as Frequency Domain Resource Allocation (FDRA), Time Domain Resource Allocation (TDRA), Frequency Hopping Flag (FH flag), Modulation and Coding Scheme (MCS), Transmission Control Protocol (TPC), and Antenna Port.

[0548] In some embodiments, the DCI may be a fallback DCI or a non-fallback DCI.

[0549] In some embodiments, for indications using a new field, the non-fallback DCI includes the new field in response to enabling the OCC scheme combination mechanism; or, in response to disabling the OCC scheme combination mechanism, the non-fallback DCI does not include the new field.

[0550] In some embodiments, as shown in Table 1, even if the OCC scheme combination mechanism is enabled, the index of the OCC length table can be used to enable one or more of the OCC schemes participating in the combination, for example, by taking the value 4, thereby enabling the use of an independent OCC scheme. Alternatively, the protocol presets that the gNB always configures or indicates a row in the table (the use of this table is always enabled), and the table also contains a row with all 1 values ​​(that is, the sequence length of different OCC schemes is 1). The terminal enables the combination mechanism by using one of the rows configured or indicated by the gNB. Based on this, the previous embodiment will no longer be applicable (description of the newly added field).

[0551] Table 1:

[0552] Index Intra-symbol OCC length Inter-slot OCC length 0 2 4 1 4 2 2 2 2 3 8 1 4 4 5 5 2 1 6 1 2 7 1 4

[0553] In some embodiments, a second mapping relationship is determined based on the protocol preset rules or the configuration information between the index and the OCC sequence lengths of at least two OCC mechanisms in any OCC mechanism combination; the OCC sequence lengths corresponding to at least two OCC mechanisms in the OCC mechanism combination are determined based on the first information and a second mapping relationship 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 the second mapping relationship corresponding to an OCC mechanism combination.

[0554] It should be noted that this disclosure may involve multiple combinations of OCC mechanisms, such as four combinations, and the second information may also indicate one of the four combinations.

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

[0556] The following is an explanation using Example 2:

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

[0558] In some embodiments, if the sequence length combination table is preset by the protocol, then different scheme combination mechanisms can have independent preset tables (corresponding to the second mapping relationship), or different schemes can 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 of gNB configuration or indication (i.e. configuration information).

[0560] In some embodiments, the gNB can be configured or instructed via RRC, MAC CE, or DCI.

[0561] In some embodiments, a new MAC CE can be created (using a new LCID or reusing an existing MAC CE), or it can be indicated through a reserved field in the MAC subheader of the MAC SDU or CE.

[0562] In some embodiments, if indicated via DCI, existing fields can be reused, or new fields can be added. The reuse of existing fields includes at least a portion of bits from fields such as FDRA, TDRA, FH flag, MCS, TPC, and antenna port.

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

[0564] In some embodiments, for indications using a new field, the non-fallback DCI includes the new field in response to enabling the OCC scheme combination mechanism; or, in response to disabling the OCC scheme combination mechanism, the non-fallback DCI does not include the new field.

[0565] In some embodiments, assuming the protocol pre-supports Scheme 1 and Scheme 2, two independent OCC length tables are pre-defined for each of the two different combinations. A possible example is shown in Tables 2 and 3 (corresponding to the second mapping relationship). The terminal needs to determine the OCC scheme combination method explicitly or implicitly to determine which OCC length configuration table to use (whether it's the table for Scheme 1 or Scheme 2, which can be indicated by the second information). Additionally, one row in either table may contain all 1s (the value is 1 for all OCC lengths). In this case, the corresponding OCC scheme combination can be enabled or disabled based on the gNB's dynamic signaling.

[0566] Table 2:

[0567] Index Intra-symbol OCC length Inter-slot OCC length 0 2 4 1 4 2 2 2 2 3 8 1 4 4 1 5 2 1 6 1 2 7 1 4

[0568] Table 3:

[0569] Index Inter-symbol OCC length Inter-slot OCC length 0 2 4 1 4 2 2 8 1 3 4 1 4 2 1 5 1 2 6 1 4 7 1 8

[0570] In some embodiments, it is assumed that the protocol pre-supports scheme 1 and scheme 2. For the two different combinations, the protocol pre-sets a common OCC length table (corresponding to the third mapping relationship). A possible example is shown in Table 4.

[0571] Table 4:

[0572] Index Intra-symbol OCC length Inter-symbol OCC length Inter-slot OCC length 0 1 2 4 1 1 4 2 2 1 3 1 3 2 4 1 4 4 2 1 5 4 1 2 6 2 1 4 7 1 1 3 8 1 2 2 9 1 2 1 10 1 4 1 11 4 1 1 12 3 1 1 13 2 2 2 14 1 1 2 15 1 1 1

[0573] Under this mechanism, the choice of which OCC scheme combination to use, or whether an OCC scheme is enabled, can be determined based on the table index (i.e., the second information indicator) configured or indicated by the gNB, without requiring additional explicit enable or disable parameters. Furthermore, based on Table 4, the following approach is also supported: the protocol can support any combination of the three OCC schemes (including combining all three). For example, if the gNB indicates index 15 in the table below, it means all OCC schemes are disabled. Alternatively, if the gNB indicates index 0, it means the combination of inter-symbol and inter-slot OCC is enabled, and the intra-symbol OCC scheme is disabled. Of course, if the protocol defaults to only supporting schemes 1 and 2, or independent OCC schemes (without combination), then index 13 in Table 4 is an inappropriate example.

[0574] In some embodiments, the enabling or disabling of at least one of the OCC mechanisms in the OCC mechanism combination is determined based on protocol preset rules and / or configuration information received from the network device.

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

[0576] In some embodiments, based on the first information and the fourth mapping relationship, the OCC sequence length corresponding to at least one of the OCC mechanisms in the OCC mechanism combination is determined; wherein, 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.

[0577] In some embodiments, a fifth mapping relationship is determined based on the protocol preset rules or the configuration information, between the index and the OCC sequence lengths of at least two OCC mechanisms in any OCC mechanism combination; based on the first information and a fifth mapping relationship determined based on the second information, the enabling or disabling of at least one OCC mechanism in the OCC mechanism combination is determined; 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 the fifth mapping relationship corresponding to an OCC mechanism combination.

[0578] In some embodiments, a sixth mapping relationship is determined based on the protocol preset rules or the configuration information, between the index, at least two OCC mechanisms in the combination of at least two OCC mechanisms, and the OCC sequence length of the at least two OCC mechanisms in the combination of at least two OCC mechanisms; based on the first information and the sixth mapping relationship, the enabling or disabling of at least one of the OCC mechanisms in the OCC mechanism combination is determined; wherein, the first information is information received from the network device, and the first information is used to indicate the index.

[0579] The following example, Example 3, illustrates the configuration of an OCC length union table for OCC scheme combinations in gNB.

[0580] In some embodiments, the OCC length of different OCC schemes is determined based on a row in a signaling instruction table such as MAC CE, MAC subheader, or DCI (i.e., indicated by first information), and / or the enabling or disabling of different OCC schemes, as well as the enabling or disabling of OCC scheme combinations.

[0581] In some embodiments, the protocol supports only one of the OCC scheme combinations (one of Schemes 1, 2, 3, and 4). The gNB configuration can then configure the OCC length table as shown in Embodiment 1. Unlike Embodiment 1, enabling and disabling an OCC scheme can be directly achieved through the configuration of the OCC Sequence table without requiring additional parameters. For example, if the OCC scheme combination is disabled, there is no need to configure the OCC length table. Alternatively, if one of the OCC schemes participating in the OCC scheme combination is never enabled, the gNB may not configure the corresponding OCC length, or may configure the corresponding OCC length to always be 1 (with a value of 1 in every row). Alternatively, one or more OCC schemes can be dynamically enabled or disabled (in some cases, only the remaining OCC schemes participating in the OCC scheme combination, excluding the enabled OCC scheme, may be used).

[0582] In some embodiments, the protocol can support OCC scheme combinations of several schemes (several of Schemes 1, 2, 3, and 4). Specific configuration methods are shown in Embodiment 2, which can be configured as independent OCC length tables or as combined OCC length tables. If configured as independent OCC length tables, only one Direction's OCC length table can be configured at a given time, or multiple scheme OCC scheme combination tables can be configured semi-statically, with the OCC scheme combination table dynamically disabled or enabled via MAC CE or DCI, or switching between OCC length tables. Furthermore, for the combined OCC length table configuration, as shown in Table 5, if a scheme (one of Schemes 1, 2, 3, and 4) is not enabled, then correspondingly, there will not be a situation where the OCC length of other OCC schemes is 1, while the OCC length of all OCC schemes under the corresponding OCC scheme combination (disabling OCC scheme combination) is not 1.

[0583] In some embodiments, even if a certain OCC scheme combination is disabled, one or more schemes (a subset, not the entire set) participating in the OCC scheme combination can still be enabled. Furthermore, assuming the protocol supports schemes 1, 2, 3, and 4, even if scheme 4 is disabled via RRC configuration of the OCC length table, one or more (or all) of schemes 1, 2, or 3 can still be semi-statically configured to be enabled (with corresponding OCC length configurations), or one or more OCC schemes can be configured for independent use. That is, flexible RRC configuration is employed, and the protocol imposes no constraints.

[0584] Table 5:

[0585] Index Intra-symbol OCC length Inter-symbol OCC length Inter-slot OCC length 0 1 2 4 1 1 4 2 2 1 3 1 3 2 4 1 4 4 2 1 5 4 1 2 6 2 1 4 7 1 1 3 8 1 2 2 9 1 2 1 10 1 4 1 11 4 1 1 12 3 1 1 13 2 2 2 14 1 1 2 15 1 1 1

[0586] In some embodiments, the gNB provides specific OCClength table index indications based on signaling such as MAC CE, MAC subheader, or DCI. The specific method is similar to the indication method based on MAC CE, MAC subheader, or DCI described in Embodiments 1 or 2.

[0587] In some embodiments, a terminal receives a first message sent by a network device; wherein the first message includes the first information; the first message includes at least one of the following: a Radio Resource Control (RRC) message; a Media Access Control (MAC) Control Element (CE) message; and a Downlink Control Information (DCI) message.

[0588] In some embodiments, the terminal receives third information sent by the network device; wherein the third information is used to indicate the length of the OCC sequence corresponding to at least one of the OCC mechanisms.

[0589] In some embodiments, the terminal receives a second message sent by the network device; wherein the second message includes the third information; the second message includes at least one of the following: a Radio Resource Control (RRC) message; a Media Access Control (MAC) Control Element (CE) message; and a Downlink Control Information (DCI) message.

[0590] For example, the OCC length of at least one OCC scheme is determined by gNB configuration or indication.

[0591] For example, the signaling can be RRC signaling, DCI signaling, or MAC CE, or a combination of at least two of the above. For RRC configuration, the RRC parameter may be one of the enumerated values ​​(or indicated via a bitmap, with each bit corresponding to an OCC length), or the RRC parameter may be a codepoint, or the RRC signaling may indicate an index in a pre-defined OCC length list. The information carried by DCI or MAC CE is similar to that of RRC, and the specific fields used are similar to those in method three. Alternatively, a combination of RRC and DCI can be used to determine the OCC length. For example, RRC configures an OCC length list for an OCC scheme (e.g., the OCC length list may contain a value of OCC length = 1), and DCI, MAC CE, or MAC subheader indicates an index in the list (e.g., if OCC length = 1 is indicated, it means the OCC scheme is dynamically disabled).

[0592] In some embodiments, if the OCC length of multiple OCC schemes is determined by configuration or indication via gNB, then the OCC length of different OCC schemes is independently configured or indicated via gNB. For example, assuming that the independent RRC parameters configured via gNB determine the intra-symbol OCC length to be 2 and the inter-slot OCC length to be 4, it is conceivable to use a combination of intra-symbol and inter-slot OCC schemes. Furthermore, OCC scheme combination, or enabling or disabling of one of the OCC schemes, can be dynamically performed via DCI, MAC CE, or MAC subheader. For example, taking intra-symbol and inter-slot OCC as examples, the DCI carries two bits of enable signaling, corresponding to intra-symbol occ and inter-slot occ respectively. The value "00" can indicate that the above OCC scheme combination is dynamically disabled. If the value is "10", it means that the intra-symbol OCC is enabled and the inter-slot OCC is disabled. The terminal uses OCC length=2 to execute intra-symbol OCC.

[0593] In some embodiments, the OCC sequence length of different OCC mechanisms in the OCC mechanism combination is determined based on a first amount of allocated resources. That is, the OCC length is determined through other implicit methods.

[0594] In some embodiments, the OCC length is determined by the number of resources allocated.

[0595] 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.

[0596] For example, suppose a slot is allocated X time-domain symbols. Then, for an inter-symbol OCC, its OCC length = X / N, where N is the largest positive integer that divides X, or N is the largest positive integer that divides X excluding X itself. Alternatively, N is the smallest positive integer that divides X, or N is the largest positive integer that can be multiplied or divided by X excluding X itself.

[0597] For example, assuming X RBs are allocated within a slot, then for an intra-symbol OCC, its OCClength = X × number of subcarriers within one RB / M. The value of M is defined similarly to the value of N mentioned above, and will not be elaborated further.

[0598] 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 an independent intra / inter-symbol OCC scheme, the protocol may implicitly specify that the number of slots occupied by TBoMS = intra / inter-symbol OCC length.

[0599] In some embodiments, the OCC parameters corresponding to different OCC mechanisms in the OCC mechanism combination are determined based on the same or different methods; wherein, the methods include at least one of the following: a first method, wherein the first method is a method of determining the OCC mechanism and / or OCC sequence length based on communication protocol rule information; a second method, wherein the second method is a method of determining the OCC mechanism and / or OCC sequence length based on configuration information sent by the network device.

[0600] In some embodiments, the determination of the OCC sequence length can be achieved by using the same or different methods for different OCC schemes participating in the OCC scheme combination. For example, assuming that the protocol defaults to Scheme 1, one possible example is that inter-slot OCC multiplexing uses the protocol default method to determine the OCC sequence length L (corresponding to the first method), while intra-symbol OCC spreading uses the explicit parameters of the RRC signaling configuration to determine the OCC length (corresponding to the second method).

[0601] In some embodiments, the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on the protocol preset rules and / or the configuration information sent by the network device.

[0602] In some embodiments, the same OCC mechanism is used for different terminals, but different OCC sequence lengths are used.

[0603] In some embodiments, the OCC mechanism combination includes an OCC mechanism combination; a seventh mapping relationship is determined between all OCC mechanisms, OCC sequences and indexes in the OCC mechanism combination based on protocol preset rules or the configuration information; a sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on first information and the seventh mapping relationship; wherein, the first information is information received from the network device or information determined based on the terminal identifier, and the first information is used to indicate the index.

[0604] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each OCC mechanism combination includes at least two OCC mechanisms; at least two eighth mapping relationships are determined between all OCC mechanisms, OCC sequences, and indexes in different OCC mechanism combinations based on protocol preset rules or configuration information; a first OCC mechanism combination is determined based on fourth information; wherein the fourth information is information received from the network device; an eighth mapping relationship is determined based on the first OCC mechanism combination; and the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on the first information and the eighth mapping relationship; wherein the first information is information received from the network device or information determined based on the terminal identifier, and the first information is used to indicate the index.

[0606] In some embodiments, the OCC mechanism combination includes an OCC mechanism combination; the OCC sequence length of the OCC mechanism is at least two; a tenth mapping relationship is determined between all OCC mechanisms, OCC sequences, OCC sequence lengths, and indexes in the OCC mechanism combination based on protocol preset rules or the configuration information; the OCC sequence length of each OCC mechanism in the OCC mechanism combination is determined based on the method for determining the OCC sequence length; a tenth mapping relationship is determined based on the OCC sequence length and the OCC mechanism combination; the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on first information and the tenth mapping relationship; wherein, 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 the index.

[0607] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each OCC mechanism combination includes at least two OCC mechanisms; the OCC sequence length of the OCC mechanism is one; an eleventh mapping relationship is determined between all OCC mechanisms, OCC sequences, OCC sequence lengths, and indices in different OCC mechanism combinations based on protocol preset rules or configuration information; a first OCC mechanism combination is determined based on fourth information; wherein the fourth information is information received from the network device; an eleventh mapping relationship is determined based on the first OCC mechanism combination; and the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on the first information and the eleventh mapping relationship; 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.

[0608] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each OCC mechanism combination includes at least two OCC mechanisms; the OCC sequence length of the OCC mechanism is at least two; a twelfth mapping relationship is determined between all OCC mechanisms, OCC sequences, OCC sequence lengths, and indexes in different OCC mechanism combinations based on protocol preset rules or configuration information; a first OCC mechanism combination is determined based on fourth information; wherein the fourth information is information received from the network device; the OCC sequence length of each OCC mechanism in the first OCC mechanism combination is determined based on the OCC sequence length determination method; a twelfth mapping relationship is determined based on the OCC sequence length and the first OCC mechanism combination; the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on the first information and the twelfth mapping relationship; wherein the first information is information received from the network device or information determined based on the terminal identifier, and the first information is used to indicate the index.

[0609] In some embodiments, the OCC mechanism combination includes one OCC mechanism combination; the OCC mechanism combination includes at least two OCC mechanisms; a thirteenth mapping relationship is determined between each OCC mechanism, OCC sequence, and index in the OCC mechanism combination based on the protocol preset rules or the configuration information; at least two of the thirteenth mapping relationships are determined based on at least two OCC mechanisms in the 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 two of the thirteenth mapping relationships; wherein, 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 the index.

[0612] In some embodiments, the OCC mechanism combination includes an OCC mechanism combination; the OCC mechanism combination includes at least two OCC mechanisms; the OCC sequence length of the OCC mechanism is at least two; multiple sixteenth mapping relationships between each OCC mechanism, OCC sequence, OCC sequence length, and index in the OCC mechanism combination are determined based on the protocol preset rules or the configuration information; the OCC sequence length of each OCC mechanism in the first OCC mechanism combination is determined based on the method for determining the OCC sequence length; at least one sixteenth mapping relationship is determined from the multiple sixteenth mapping relationships based on the OCC sequence length and at least two OCC mechanisms in the first OCC mechanism combination; the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on first information and the at least one sixteenth mapping relationship; wherein, 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 the index.

[0613] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each OCC mechanism combination includes at least two OCC mechanisms; the OCC sequence length of the OCC mechanism is one; multiple seventeenth mapping relationships between each OCC mechanism, OCC sequence, OCC sequence length, and index in different OCC mechanism combinations are determined based on the protocol preset rules or the configuration information; a first OCC mechanism combination is determined based on fourth information; wherein the fourth information is information received from the network device; at least one seventeenth mapping relationship is determined from multiple seventeenth mapping relationships based on at least two OCC mechanisms in the first OCC mechanism combination; the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on the first information and the at least one seventeenth mapping relationship; wherein the first information is information received from the network device or information determined based on the terminal identifier, and the first information is used to indicate the index.

[0614] In some embodiments, the OCC mechanism combination includes at least two OCC mechanism combinations; each OCC mechanism combination includes at least two OCC mechanisms; the OCC sequence length of the OCC mechanism is at least two; multiple eighteenth mapping relationships between each OCC mechanism, OCC sequence, OCC sequence length, and index in different OCC mechanism combinations are determined based on the protocol preset rules or the configuration information; a first OCC mechanism combination is determined based on fourth information; wherein the fourth information is information received from the network device; the OCC sequence length of each OCC mechanism in the first OCC mechanism combination is determined based on the OCC sequence length determination method; at least one eighteenth mapping relationship is determined from multiple eighteenth mapping relationships based on the OCC sequence length and at least two OCC mechanisms in the first OCC mechanism combination; the sequence corresponding to the OCC mechanism in the OCC mechanism combination is determined based on the first information and the at least one eighteenth mapping relationship; wherein the first information is information received from the network device or information determined based on the terminal identifier, and the first information is used to indicate the index.

[0615] In some embodiments, the OCC mechanism combination includes at least two OCC combinations; each OCC mechanism combination includes at least two OCC mechanisms; determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on protocol preset rules and / or configuration information sent by the network device includes: determining multiple nineteenth mapping relationships between each OCC mechanism, OCC sequence, OCC sequence length, and index in the OCC mechanism combination based on the protocol preset rules 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 the OCC sequence length determination method; determining at least two nineteenth mapping relationships from multiple nineteenth mapping relationships based on the OCC sequence length and at least two OCC mechanisms in the first OCC mechanism combination; determining the sequence corresponding to the OCC mechanism in the OCC mechanism combination based on first information and the at least two 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.

[0616] In some embodiments, different OCC mechanisms use the same sequence type; determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on protocol preset rules and / or configuration information sent by the network device includes: determining a twentieth mapping relationship between the OCC sequence index and the OCC sequence length based on the protocol preset rules or the configuration information for the adopted sequence type; determining the OCC sequence corresponding to the OCC mechanism in the OCC mechanism combination based on the protocol preset rules, first information, and the twentieth mapping relationship; wherein, the first information is information sent by the network device or information determined based on the terminal identifier, and the first information is used to indicate the index.

[0617] In some embodiments, the protocol preset rule is: the twenty-first mapping relationship is determined based on the twentieth mapping relationship, the OCC mechanism, and the OCC sequence length of the OCC mechanism.

[0618] For example, the protocol supports multiple OCC mechanism combinations, each with its own independent union table. The terminal first needs to determine the various mapping relationships under different OCC mechanism combinations (mainly considering that different OCC lengths have different mapping relationships). Then, based on configuration signaling, a unique OCC mechanism combination is determined. Furthermore, based on the aforementioned OCC sequence length determination method, the OCC sequence length of each OCC mechanism in that combination is determined. Finally, a unique mapping relationship is determined. Based on the mapping relationship and configuration information (index information), the sequence of each OCC scheme for the current terminal is determined.

[0619] For example, the OCC length of different OCC mechanisms can also be unique. In this case, a combination of OCC mechanisms has a unique mapping table.

[0620] For example, Method 1: Determine the sequence of each OCC scheme in the OCC scheme combination through a joint instruction scheme.

[0621] In some embodiments, the protocol pre-defines a combined table of OCC sequences for different OCC schemes within the OCC scheme combination. Alternatively, the gNB configures a combined table of OCC sequences for different OCC schemes within the OCC scheme combination.

[0622] In some embodiments, assuming the use of intra-symbol OCC and inter-slot OCC, and further assuming that the intra-symbol OCC length is 4 and the inter-slot OCC length is 2, then a possible combined OCC sequence table is shown in Table 6. Furthermore, for a specific terminal, the OCC sequence index (corresponding to the first information) carried in the DCI, MAC signaling, or RRC signaling sent by the gNB can be used to determine the OCC sequence for different OCC schemes.

[0623] Table 6:

[0624]

[0625] In some embodiments, for OCC sequence index indication or OCC sequence indication via DCI, a new field (applicable to non-fallback DCI) or an existing field can be used. For the method of using existing fields, at least one of the following can be used: at least a portion of the bits of fields such as FDRA, TDRA, FH flag, MCS, TPC, antennaport, etc. For example, the OCC sequence index for different OCC schemes can be implicitly determined by the antenna port field carried in the DCI.

[0626] In some embodiments, taking Table 7 as an example, the protocol presupposes a one-to-one mapping between DMRS ports and OCC sequence indices. For example, DMRS port 0 corresponds to OCC sequence index 0, DMRS port 1 corresponds to OCC sequence index 1, and so on. Furthermore, the terminal can determine the DMRS port through the antenna port field carried by the DCI, thereby determining the OCC sequence index it uses. Ultimately, the OCC sequences corresponding to the intra-symbol OCC and inter-slot OCC can be determined. This method can also be applied to other schemes described below, which will not be elaborated further.

[0627] Table 7:

[0628] Value Number of DMRS CDM groups without data DMRS port Number of preambles 0 2 0 1 1 2 1 1 2 2 2 1 3 2 3 1 4 2 0 2 5 2 1 2 6 2 2 2 7 2 3 2 8 2 4 2 9 2 5 2 10 2 6 2 11 2 7 2 12-15 Reserved Reserved Reserved

[0629] In some embodiments, different combinations of OCC lengths can have different OCC sequence combination tables. For example, the protocol defaults to using an intra-symbol and inter-slot OCC combination.

[0630] In some embodiments, the OCC length of the two OCC schemes may 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 combinations of OCC lengths.

[0631] Furthermore, the protocol may pre-define various OCC scheme combination methods. Different OCC sequence combination tables can exist for different OCC scheme combination methods.

[0632] For example: the sequence of each OCC scheme in the OCC scheme combination is determined by a joint instruction scheme.

[0633] In some embodiments, the protocol pre-defines independent OCC sequence tables for different OCC schemes. Different OCC sequence lengths may have different OCC sequence tables. Furthermore, the protocol pre-defines certain rules that allow the terminal to determine the mapping relationship between the OCC sequence indication value carried in the DCI and different OCC sequences. Further, for a specific terminal, the OCC sequence index for different OCC schemes can be determined through the indication field carried in the DCI.

[0634] In some embodiments, the explanation is further elaborated using an intra-symbol OCC length of 4 and an inter-slot OCC length of 2 as an example. A possible example of an OCC sequence table is shown in Table 8. Assume that the value range for indicating the OCC sequence carried in the DCI is 0 to 7. Then, the following mapping relationship can exist between it and the intra-symbol OCC and inter-slot OCC sequence: OCC sequence index in DCI = floor(inter-slot OCC sequence index) × intra-symbol OCC length + intra-symbol OCC sequence index. Wherein, the intra-symbol OCC length is determined in any embodiment of this disclosure.

[0635] Table 8:

[0636]

[0637] Table 9:

[0638]

[0639] For example, different OCC mechanisms have one or more independent OCC sequence tables (depending on whether the OCC length is a unique value preset by the protocol). The terminal first determines the OCC sequence table corresponding to each OCC length (if the length is more than one) for each OCC mechanism based on the protocol. Then, it determines the OCC scheme under the combination of OCC mechanisms (assuming there are M schemes) and the corresponding OCC length, thereby determining M tables. Then, based on the M indices indicated by the gNB, it determines the OCC sequence corresponding to each of the M OCC schemes.

[0640] For example, with at least two independent tables (or possibly three or more, with different occschemes corresponding to different tables), the terminal first determines N independent tables, then, based on gNB configuration / configuration information, determines which M tables from the N tables to use, and finally, based on the configuration information of the table indexes, determines the occsequence of the current occ scheme. The M tables correspond to M configuration information.

[0641] In some embodiments, for a specific OCC scheme combination, one possible approach is that different OCC schemes use the same sequence type. For example, for scheme 2, both inter-symbol and inter-slot OCCs use Walsh sequences. Then, for Walsh sequences, the protocol pre-defines OCC sequence tables with different OCC sequence lengths (corresponding to the tenth mapping relationship). Furthermore, the protocol pre-defines the mapping method between OCC sequences of different OCC schemes and the OCC sequences in the table (corresponding to the eleventh mapping relationship). Further, for a specific terminal, the OCC sequence index of different OCC schemes is determined by a row in the table indicated by the DCI. Taking inter-symbol OCC length = 2 and inter-slot OCC length = 2 as an example, the OCC sequence table with a length of 4 is shown in Table 10. One possible pre-definement rule is as follows: the first two characters of a sequence of length 4 are the inter-symbol OCC sequence; based on the OCC Seq of length 4 and the first two OCC sequence values, the inter-slot OCC Seq value can be determined. For example, based on the rules above, Table 10 can be transformed into Table 11.

[0642] Table 10:

[0643]

[0644]

[0645] Table 11:

[0646] OCC sequence Index Length 2 Inter-symbol Length 2 Inter-slot 0 +1 +1 +1 +1 1 +1 -1 +1 +1 2 +1 +1 +1 -1 3 +1 -1 +1 -1

[0647] In some embodiments, the terminal receives fifth information sent by the network device; wherein the fifth information is used to indicate at least one OCC sequence corresponding to the OCC mechanism.

[0648] In some embodiments: the sequence of each OCC scheme in the OCC scheme combination is determined by independent parameters indicated by gNB.

[0649] In some embodiments, configuration or indication can be performed via RRC signaling, MAC signaling, or DCI, with the specific indication method being the same as in Method 1. The protocol defaults, or the gNB configures the OCC sequence table. Different OCC sequences use different OCC sequence tables. For a specific terminal, the index of the OCC sequence table is independently indicated using the same field or different bits of different fields to determine the sequence for different OCC schemes.

[0650] In some embodiments, the sequence of each OCC scheme is determined implicitly.

[0651] For example, the OCC sequence index can be determined using the terminal identifier (UEID), such as the Cell Radio Network Temporary Identifier (C-RNTI). Both the gNB and the terminal determine the OCC sequence index based on the same criteria.

[0652] For example, assuming the use of intra-symbol and inter-slot OCC, with an intra-symbol OCC length of 2 and an inter-slot OCC length of 2, then mod(C-RNTI, 4) = 0 / 1 / 2 / 3, where 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), and (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 Method 1 / 2, or the OCC sequence index on the left side of the formula described in Method 1-2. When performing OCC scheduling, the gNB will schedule C-RNTI with mod(C-RNTI, 4) = 0 / 1 / 2 / 3 for OCC multiplexing on the same time-frequency domain resource block. The terminal and the base station determine the occsequence based on the same rules.

[0653] Furthermore, in the above methods, if a new field or an existing field is used to indicate the OCC sequence index, the number of bits used in the OCC sequence index is related to the OCC length of different OCC schemes in the OCC scheme combination.

[0654] In some embodiments, the determination of the OCC sequence index can be carried out in the same or different ways for different OCC schemes participating in the OCC scheme combination. For example, it is assumed that, in Scheme 1, inter-slot OCC multiplexing uses the implicit method of method 3 to determine the OCC sequence, while for intra-symbol OCC spreading, the gNB explicit indication method is used to determine the OCC sequence.
