As shown in FIG. 1A, the communication system 100 can include a terminal, a network device.

[0331] The following embodiments of the present disclosure can be applied to the communication system 100 illustrated in FIG. 1A, or part of the subjects, but are not limited thereto. The subjects illustrated in FIG. 1A are examples, and the communication system can include all or part of the subjects in FIG. 1A, or other subjects other than those in FIG. 1A. The number and form of each subject is arbitrary, and the connection relationship between the subjects is an example.

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

[0333] Optionally, the "multi-user multiplexing transmission of PUSCH" described above can be understood as: multiple terminals multiplex PUSCH on the same time-frequency resource, for example, the PUSCH of different terminals can correspond to different OCC sequences, when different terminals transmit PUSCH, the OCC sequence corresponding to the PUSCH of the terminal can be used to weight the PUSCH of the terminal, and each terminal can transmit the weighted PUSCH on the same time-frequency resource to the network device. When the network device receives the weighted PUSCH transmitted by each terminal on the same time-frequency resource, it can determine the PUSCH of each terminal based on the OCC sequence corresponding to the PUSCH of each terminal, so as to realize the multiplexing transmission of PUSCH of multiple terminals on the same time-frequency resource. Optionally, in some embodiments, when the terminal multiplexes PUSCH based on the OCC sequence, each sequence value in an OCC sequence needs to be mapped to the same frequency domain position, that is, the time domain resource unit (such as symbol, time slot, etc.) mapped by each sequence value in an OCC sequence needs to pass through the same channel, so that the network device can successfully decode the OCC sequence multiplexed PUSCH. For example, FIG. 1B is a structure diagram of OCC sequence multiplexed PUSCH according to an embodiment of the present disclosure, as shown in FIG. 1B, the sequence length of the OCC sequence (or OCC-length, OCC multiplexing user number, OCC maximum multiplexing user number, etc.) is 4, that is, the OCC sequence includes 4 sequence values, each sequence value is mapped to the same frequency domain position, so as to ensure that the receiving end can successfully decode the OCC sequence multiplexed PUSCH.

[0334] Optionally, in some embodiments, when multiplexing PUSCH based on the OCC sequence, frequency hopping is usually performed to reduce transmission interference and ensure link transmission performance. Optionally, the frequency hopping manner can include at least one of the following: intra-slot frequency hopping, inter-symbol frequency hopping, inter-slot frequency hopping, and inter-repetition transmission frequency hopping. Optionally, intra-slot frequency hopping can be understood as: frequency hopping between different symbols in a slot, so that different symbols in a slot correspond to different frequency domain positions, and the frequency hopping manners of different slots can be the same, so that the symbols at the same position in different slots correspond to the same frequency domain position; optionally, inter-symbol frequency hopping can be understood as: frequency hopping between different symbols, so that different symbols correspond to different frequency domain positions; optionally, inter-slot frequency hopping can be understood as: frequency hopping with a slot as a granularity, different slots correspond to different frequency domain positions, and the symbols in the same slot correspond to the same frequency domain position; optionally, inter-repetition transmission frequency hopping can be understood as: frequency hopping with a repetition transmission as a granularity, different repetition transmissions correspond to different frequency domain positions, and the symbols in the same repetition transmission correspond to the same frequency domain position.

[0335] When frequency hopping is performed, the OCC sequence may be mapped to a time domain length in which frequency hopping occurs, so that different sequence values in the OCC sequence are mapped to different frequency domain positions, which may cause the receiving end to fail to correctly decode the PUSCH multiplexed by the OCC sequence, and affect the transmission performance of the PUSCH. Therefore, how to ensure that each sequence value in the OCC sequence is mapped to the same frequency domain position when frequency hopping is performed is a technical problem that needs to be solved at present.

[0336] Based on this, the present disclosure provides a communication method.

[0337] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises the following steps:

[0338] In step 2101, the network device configures and / or indicates a first frequency hopping manner.

[0339] Optionally, the network device can configure and / or indicate the first frequency hopping manner to the terminal, and the terminal can receive the first frequency hopping manner configured and / or indicated by the network device. Optionally, the first frequency hopping manner can be configured or indicated to the terminal by the network device based on a protocol agreement and / or autonomously determined.

[0340] Optionally, the first frequency hopping manner can be a frequency hopping manner used by the terminal when performing multi-user multiplexing transmission of the PUSCH based on the OCC sequence. The related description of the multi-user multiplexing transmission of the PUSCH can refer to the description before the embodiment of FIG. 2A.

[0341] In some embodiments, the multi-user multiplexing transmission of the PUSCH described above can include at least one of the following:

[0342] The first one is the multi-user multiplexing transmission of the PUSCH based on a symbol (i.e., Symbol-level OCC spreading).

[0343] Optionally, when the multi-user multiplexing transmission of the PUSCH is implemented based on a symbol, one sequence value in the OCC sequence can be mapped to at least one symbol of the PUSCH.

[0344] Optionally, the "mapping" described above can be understood as a weighting process (or weighting multiplication), and the "one sequence value in the OCC sequence can be mapped to at least one symbol of the PUSCH" described above can be understood as multiplying the PUSCH signal carried on the at least one symbol by one sequence value in the OCC sequence.

[0345] For example, assuming that the total number of symbols in a PUSCH transmission is 20, the 20 symbols can be denoted as Symbol(i), i = 0, 1, …, 19, and assuming that the OCC sequence includes two sequence values, such as W(0) and W(1), and one sequence value of the OCC sequence can be mapped to 2 symbols continuously, W(0) of the OCC sequence can be mapped to Symbol(0) and Symbol(1) (i.e., the PUSCH signals carried on the symbols Symbol(0) and Symbol(1) can be multiplied by W(0)), and W(1) of the OCC sequence can be mapped to Symbol(2) and Symbol(3) (i.e., the PUSCH signals carried on the symbols Symbol(2) and Symbol(3) can be multiplied by W(1)). Then, the OCC sequence is repeatedly mapped, such as W(0) can be mapped to Symbol(4) and Symbol(5) (i.e., the PUSCH signals carried on the symbols Symbol(4) and Symbol(5) can be multiplied by W(0)), and W(1) of the OCC sequence can be mapped to Symbol(6) and Symbol(7) (i.e., the PUSCH signals carried on the symbols Symbol(6) and Symbol(7) can be multiplied by W(1)), and so on, to complete the mapping of the OCC sequence to the PUSCH. Each terminal can use the above method to map the OCC sequence of the PUSCH of the terminal to the PUSCH, to achieve multi-user multiplexing transmission of the PUSCH of the terminal.

[0346] The second: PUSCH multi-user multiplexing transmission based on a slot (Slot) (i.e., Slot-level OCC multiplexing).

[0347] Optionally, when the PUSCH multi-user multiplexing transmission is implemented based on a slot, one sequence value in the OCC sequence can be mapped to at least one slot of the PUSCH.

[0348] For example, assuming that the total number of slots in one PUSCH transmission is 4, the 4 slots can be represented as Slot(i), i=0, 1, 2, 3, and assuming that the OCC sequence includes 2 sequence values, for example, W(0), W(1), and one sequence value of the OCC sequence can be mapped to 2 slots successively, W(0) of the OCC sequence can be mapped to Slot(0) and Slot(1) (i.e., the PUSCH signals carried on the slots Slot(0) and Slot(1) can be multiplied by W(0)), W(1) of the OCC sequence can be mapped to Slot(2) and Slot(3) (i.e., the PUSCH signals carried on the slots Slot(2) and Slot(3) can be multiplied by W(1)), and each terminal can use the above method to map the OCC sequence of the PUSCH of the terminal to the PUSCH, so as to realize the multi-user multiplexing transmission of the PUSCH of the terminal.

[0349] The third: multi-user multiplexing transmission of PUSCH realized based on repetition.

[0350] Optionally, when the multi-user multiplexing transmission of PUSCH is realized based on repetition, one sequence value in the OCC sequence can be mapped to at least one repetition of the PUSCH.

[0351] For example, assuming that the total number of repetitions in one PUSCH transmission is 4, the 4 repetitions can be represented as R(i), i=0, 1, 2, 3, and assuming that the OCC sequence includes 2 sequence values, for example, W(0), W(1), and one sequence value of the OCC sequence can be mapped to 2 repetitions successively, W(0) of the OCC sequence can be mapped to R(0) and R(1) (i.e., the PUSCH signals carried on the 0th repetition R(0) and the 1st repetition R(1) can be multiplied by W(0)), W(1) of the OCC sequence can be mapped to R(2) and R(3) (i.e., the PUSCH signals carried on the 2nd repetition R(2) and the 3rd repetition R(3) can be multiplied by W(1)), and each terminal can use the above method to map the OCC sequence of the PUSCH of the terminal to the PUSCH, so as to realize the multi-user multiplexing transmission of the PUSCH of the terminal.

[0352] The above describes the multi-user multiplexing transmission of the terminal PUSCH in detail, and the first frequency hopping mode is essentially a frequency hopping mode used when the terminal performs multi-user multiplexing transmission on the PUSCH based on the OCC sequence. Alternatively, the first frequency hopping mode can be that no frequency hopping is performed, that is, the terminal does not hop frequency when performing multi-user multiplexing transmission on the PUSCH based on the OCC sequence. At this time, in some embodiments, when the network device configures the terminal with OCC multiplexing related parameters (such as time-domain OCC multiplexing related parameters) for performing multi-user multiplexing transmission on the PUSCH, or time-domain OCC multiplexing is enabled, the network device will not configure a radio resource control (RRC) parameter for frequency hopping. The RRC parameter may, for example, include at least one of the following: frequency hopping frequencyhopping parameter, frequency hopping downlink control information frequencyhoppingDCI-0-1, frequencyhoppingDCI-0-2; and / or in other embodiments, when the first frequency hopping mode is that no frequency hopping is performed, if the network device configures the terminal with OCC multiplexing related parameters for performing multi-user multiplexing transmission on the PUSCH, or time-domain OCC multiplexing is enabled, the network device will not set the FH flag field in the scheduling downlink control information (DCI) of the PUSCH to 1, so that the terminal does not hop frequency. In some embodiments, when the first frequency hopping mode is that no frequency hopping is performed, the network device can also send a first signaling to the terminal, which can be used for resource allocation to determine the transmission resource of the PUSCH by the terminal.

[0353] Alternatively, in other embodiments, the first frequency hopping mode described above can also be that frequency hopping is performed. When the first frequency hopping mode is that frequency hopping is performed, the first frequency hopping mode can be different for the different multi-user multiplexing transmission modes (i.e., the first to third modes described above).

[0354] Optionally, in some embodiments, when the PUSCH transmission occupies one slot, and the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one symbol of the PUSCH, if the network device configures the terminal with at least one of frequencyhopping, frequencyhoppingDCI-0-1, and frequencyhoppingDCI-0-2; and / or, if the FH flag field in the DCI sent by the network device to the terminal is set to 1, the first frequency hopping manner can be intra-slot frequency hopping. In some embodiments, the first frequency hopping manner can satisfy a first condition, and the first condition includes at least one of the following:

[0355] No frequency hopping occurs between at least one symbol mapped by each sequence value in one OCC sequence;

[0356] Mod (the time domain length of each hop, the total number of symbols mapped by one OCC sequence) = 0; the Mod function is a modulo function.

[0357] Optionally, in the actual frequency hopping in the communication system, the actual time domain length of each hop specifically includes a demodulation reference signal (DMRS) symbol and a data symbol. It should be emphasized that in some embodiments of the present disclosure, the “time domain length of each hop” mentioned can not include the symbol occupied by the DMRS.

[0358] In some embodiments, by causing the first frequency hopping manner to satisfy the first condition, it is ensured that no frequency hopping occurs in the time domain length mapped by all sequence values of the OCC sequence of the PUSCH, so that each sequence value in the OCC sequence of the PUSCH can be mapped to the same frequency domain position, thereby enabling the network device to successfully decode the PUSCH transmitted based on the OCC sequence, which not only realizes the OCC multiplexing transmission of the PUSCH, but also successfully realizes the frequency hopping of the PUSCH, thereby not only realizing the uplink capacity enhancement, but also reducing the transmission interference and ensuring the link transmission performance.

[0359] Optionally, in some embodiments, when the PUSCH transmission occupies multiple slots, and the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one symbol of the PUSCH; if the type of the PUSCH is PUSCH repetition type A or multi-slot transmission block (TBoMS) PUSCH or multi-slot transmission block PUSCH with repetition, and the OCC mapping of each OCC sequence of the PUSCH does not cross slots, it is determined that the first frequency hopping manner is not intra-slot frequency hopping, but can be inter-slot frequency hopping or inter-repetition frequency hopping. For the PUSCH repetition type A or multi-slot transmission block PUSCH or multi-slot transmission block PUSCH with repetition whose OCC mapping does not cross slots, one slot contains a complete PUSCH repetition, on this basis, when inter-slot frequency hopping or inter-repetition frequency hopping is performed, the complete PUSCH repetition can not be frequency-hopped, and the OCC mapping of the PUSCH also does not cross repetitions, thereby ensuring that the time domain length mapped by all sequence values of the OCC sequence of the PUSCH does not occur frequency hopping, and ensuring that each sequence value in the OCC sequence of the PUSCH can be mapped to the same frequency domain position, so that the network device can successfully decode the PUSCH transmitted based on the OCC sequence.

[0360] Optionally, in some embodiments, when the PUSCH transmission occupies multiple slots, and the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one symbol of the PUSCH, if the type of the PUSCH is PUSCH repetition type A or TBoMS PUSCH or multi-slot transport block PUSCH repetition (TBoMS PUSCH with repetition), and if the network device configures the terminal with at least one of frequencyhopping, frequencyhoppingDCI-0-1, frequencyhoppingDCI-0-2, and / or if the FH flag field in the DCI sent by the network device to the terminal is set to 1, then the first frequency hopping manner can be intra-slot frequency hopping or inter-symbol frequency hopping. Optionally, the first frequency hopping manner satisfies the first condition. Similarly, by making the first frequency hopping manner satisfy the first condition, it is ensured that no frequency hopping occurs within the time domain length mapped by all sequence values of the OCC sequence of the PUSCH, and it is ensured that each sequence value in the OCC sequence of the PUSCH can be mapped to the same frequency domain position, so that the network device can successfully decode the PUSCH transmitted based on the OCC sequence.

[0361] Optionally, in some embodiments, when the PUSCH transmission occupies multiple slots, and the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one symbol of the PUSCH, and the multi-user multiplexing transmission of the PUSCH also satisfies a second condition, then the first frequency hopping manner is inter-slot frequency hopping or inter-repetition transmission frequency hopping. Optionally, the second condition can include at least one of the following:

[0362] The OCC mapping of each OCC sequence of the PUSCH does not cross slots or does not cross repetition transmissions.

[0363] Mod (the number of symbols occupied by the PUSCH transmission in each slot or each repetition transmission, the sequence length L of the OCC sequence) = 0.

[0364] Optionally, the number of symbols occupied by the PUSCH transmission in each slot or each repetition transmission does not include the symbols occupied by the DMRS.

[0365] When the multi-user multiplexing transmission of the PUSCH satisfies the second condition, it means that a complete PUSCH repetition is contained in one slot, and on this basis, when inter-slot frequency hopping or inter-repetition frequency hopping is performed, the frequency hopping does not occur within the complete PUSCH repetition, and the OCC mapping of the PUSCH does not cross the repetitions, thereby ensuring that the time domain length mapped by each sequence value of the OCC sequence of the PUSCH does not occur frequency hopping, and ensuring that each sequence value in the OCC sequence of the PUSCH can be mapped to the same frequency domain position, so that the network device can successfully decode the PUSCH transmitted based on the OCC sequence.

[0366] Optionally, in still other embodiments, when the PUSCH transmission occupies multiple slots, and the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one slot of the PUSCH, if the type of the PUSCH is PUSCH repetition type A or TBoMS PUSCH or multi-slot transport block PUSCH repetition (TBoMS PUSCH with repetition), and the OCC mapping of each OCC sequence of the PUSCH does not cross the slots, it is determined that the first frequency hopping manner is intra-slot frequency hopping. When one sequence value in the OCC sequence is mapped to at least one slot, and the OCC mapping of each OCC sequence of the PUSCH does not cross the slots, if intra-slot frequency hopping is performed, it can be ensured that the frequency hopping manner within the time domain length mapped by each sequence value of the OCC sequence is the same, thereby ensuring that different sequence values in the OCC sequence are respectively mapped to the same frequency domain position, so that the network device can successfully decode the PUSCH transmitted based on the OCC sequence.

[0367] Optionally, in still other embodiments, when the PUSCH transmission occupies multiple slots, and the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one slot of the PUSCH, or one sequence value in the OCC sequence is mapped to at least one repetition of the PUSCH, it is determined that the first frequency hopping manner is inter-slot frequency hopping or inter-repetition frequency hopping. In some embodiments, the first frequency hopping manner satisfies a third condition, and the third condition can include at least one of the following:

[0368] Frequency hopping does not occur between at least one slot or at least one repetition mapped by each sequence value in one OCC sequence;

[0369] Mod (time domain length of each hop, total number of slots or total number of repetitions mapped by one OCC sequence) = 0.

[0370] Optionally, FIG. 2B is a frequency hopping diagram satisfying the third condition, according to an embodiment of the present disclosure. One square in FIG. 2B represents one time slot. As shown in FIG. 2B, the sequence length L of the OCC sequence is 2, i.e., the OCC sequence includes 2 sequence values, one sequence value is mapped to one time slot, and one OCC sequence can be mapped to 2 time slots. In this case, inter-time-slot frequency hopping can be performed, and the inter-time-slot frequency hopping satisfies the third condition, i.e., the time domain length of each hop of the inter-time-slot frequency hopping is 2 time slots, thereby ensuring that no frequency hopping occurs between the time slots to which each sequence value in one OCC sequence is mapped.

[0371] In some embodiments, by causing the first frequency hopping manner to satisfy the third condition, it is ensured that no frequency hopping occurs in the time domain length to which all sequence values of the OCC sequence of the PUSCH are mapped, and thus it is ensured that each sequence value in the OCC sequence of the PUSCH can be mapped to the same frequency domain position, thereby enabling the network device to successfully decode the PUSCH transmitted based on the OCC sequence.

[0372] Optionally, in yet some embodiments, when the PUSCH transmission occupies multiple time slots, the multi-user multiplexing transmission of the PUSCH is that one sequence value in the OCC sequence is mapped to at least one time slot of the PUSCH, or one sequence value in the OCC sequence is mapped to at least one repeated transmission of the PUSCH, and the first frequency hopping manner is determined to be inter-time-slot frequency hopping or inter-repeated-transmission frequency hopping. In some embodiments, the first frequency hopping manner satisfies the fourth condition, which can include at least one of the following:

[0373] The time domain length of each hop is one time slot or one repeated transmission;

[0374] Frequency hopping is performed in each first window occupied by the PUSCH transmission;

[0375] The same frequency hopping manner is used between different first windows.

[0376] Optionally, the first window can be understood as a window formed by time slots that map the same sequence value, or a window formed by repeated transmissions that map the same sequence value. The time domain length of the first window can be the number of time slots that map one sequence value of the OCC sequence, or the number of repeated transmissions that map one sequence value of the OCC sequence. The first window can be determined by the network device based on a protocol agreement, or can be determined by the network device autonomously. In some embodiments, the first window satisfies at least one of the following:

[0377] mod (the number of time slots or the number of repeated transmissions in the first window, 2) = 0;

[0378] The time domain length of the first window × L × F = the total time domain length of the transmission resource of the PUSCH; wherein L is the sequence length of the OCC sequence, and F is the number of repeated mappings of the OCC sequence within the total time domain length of the transmission resource of the PUSCH. Optionally, the total time domain length of the transmission resource of the PUSCH includes or does not include the unavailable slots. In some embodiments, when the type of the PUSCH is TBoMS repetitions PUSCH, the total time domain length of the transmission resource of the PUSCH = the number of slots occupied by one TBoMS transmission × the number of repetitions.

[0379] Optionally, FIG. 2C is a frequency hopping diagram that satisfies the fourth condition, according to an embodiment of the present disclosure. One square in FIG. 2C represents one slot. As shown in FIG. 2C, the sequence length L of the OCC sequence = 2, that is, the OCC sequence includes two sequence values, Value#0 and Value#1. One sequence value is mapped to two slots. Value#0 is mapped to Slot#1 and Slot#2, and Value#1 is mapped to Slot#3 and Slot#4. Slot#1 and Slot#2 can form a first window, and Slot#3 and Slot#4 can form a first window. In this case, inter-slot frequency hopping can be performed, and the inter-slot frequency hopping satisfies the fourth condition, that is, the same frequency hopping mode is used in each first window, and the time domain length of each hop is one slot.

Optionally, the slot level OCC multiplexing related parameters can include at least one of a third parameter M3, the second parameter B, and the sequence length L of the OCC sequence. The third parameter M3 means a number of slots mapped by one sequence value in the OCC sequence or a number of repeated transmissions of one sequence value, and M3 is a positive integer.

[0396] Optionally, in some embodiments, the terminal can determine the frequency hopping related parameters based on at least one of the protocol agreement, the configuration of the network device, and the indication of the network device, and determine the OCC multiplexing related parameters based on the frequency hopping related parameters. When the terminal determines the OCC multiplexing related parameters based on the frequency hopping related parameters, at least part of the parameters in the OCC multiplexing related parameters can be determined by at least one of the protocol agreement, the configuration of the network device, and the indication of the network device, wherein for the parameters in the OCC multiplexing related parameters that are not determined by the protocol agreement, the configuration of the network device, and the indication of the network device, the terminal can determine based on the frequency hopping related parameters.

Meanwhile, any one or any two of the first parameter M1, the second parameter B, and the sequence length L of the OCC sequence can be agreed by the protocol, configured by the network device, or indicated by the network device. For the values of the first parameter M1, the second parameter B, and the sequence length L of the OCC sequence that are not agreed by the protocol, configured by the network device, or indicated by the network device, the terminal can determine the values based on the time domain length of each hop.

Meanwhile, any one or any two of the third parameter M3, the second parameter B, and the sequence length L of the OCC sequence can be agreed by the protocol, configured by the network device, or indicated by the network device. For the values of the third parameter M3, the second parameter B, and the sequence length L of the OCC sequence that are not agreed by the protocol, configured by the network device, or indicated by the network device, the terminal can determine the values based on the time domain length of each hop.

[0398] Alternatively, in some other embodiments, the terminal can determine the OCC multiplexing related parameters based on at least one of a protocol agreement, a network device configuration, and a network device indication, and then determine the frequency hopping related parameters based on the OCC multiplexing related parameters.

[0399] For example, the terminal can determine the first parameter M1, the second parameter B, and the sequence length L of the OCC sequence based on at least one of a protocol agreement, a network device configuration, and a network device indication, and determine the time domain length of each hop based on the first parameter M1, the second parameter B, and the sequence length L of the OCC sequence, i.e., the time domain length of each hop = M1 x B x L. Alternatively, the terminal can determine the third parameter M3, the second parameter B, and the sequence length L of the OCC sequence based on at least one of a protocol agreement, a network device configuration, and a network device indication, and determine the time domain length of each hop based on the third parameter M3, the second parameter B, and the sequence length L of the OCC sequence, i.e., the time domain length of each hop = M3 x B x L.

[0400] Alternatively, in some other embodiments, the terminal can determine the frequency hopping related parameters and the OCC multiplexing related parameters based on at least one of a protocol agreement, a network device configuration, and a network device indication. For example, the terminal can determine the time domain length of each hop, the sequence length L of the OCC sequence, the first parameter M1, and the second parameter B based on at least one of a protocol agreement, a network device configuration, and a network device indication. Alternatively, the terminal can determine the time domain length of each hop, the sequence length L of the OCC sequence, the third parameter M3, and the second parameter B based on at least one of a protocol agreement, a network device configuration, and a network device indication.

[0401] Optionally, in some embodiments, when the multi-user multiplexing transmission of the PUSCH is the first mode described above, and the first frequency hopping manner is the intra-slot frequency hopping, the terminal does not expect that the time domain length of each hop, the first parameter M1, the second parameter B, and the sequence length L of the OCC sequence do not satisfy the first condition described above. When the multi-user multiplexing transmission of the PUSCH is the second mode or the third mode described above, the terminal does not expect that the time domain length of each hop, the third parameter M3, the second parameter B, and the sequence length L of the OCC sequence do not satisfy the third condition described above, or the terminal does not expect that the time domain length of each hop and the time domain length of the first window do not satisfy the fourth condition described above.

[0402] Step 2105, the terminal transmits the PUSCH based on the first frequency hopping manner.

[0403] Optionally, in some embodiments, when the multi-user multiplexing transmission of the PUSCH does not support frequency hopping, the steps 2102 and 2104 described above can not be performed, and in this step 2105, the terminal can determine the transmission resource of the PUSCH based on the first signaling transmitted by the network device, and transmit the PUSCH based on the transmission resource. For details of the first signaling, please refer to the description of the step 2101 described above.

[0404] Optionally, in yet some embodiments, when the multi-user multiplexing transmission of the PUSCH supports frequency hopping, the steps 2102 and 2104 described above can be performed, and then the terminal can transmit the PUSCH based on the determined first frequency hopping manner, frequency hopping related parameters, and OCC multiplexing related parameters.

[0405] In the above embodiments, when the PUSCH is subjected to OCC multiplexing, different frequency hopping manners can be adopted for various OCC multiplexing cases of the PUSCH, and conditions required to be met when frequency hopping is further limited, so as to ensure that the time domain length mapped by all sequence values of the OCC sequence of the PUSCH does not occur frequency hopping, and thus it is ensured that each sequence value in the OCC sequence of the PUSCH can be mapped to the same frequency domain position, so that the network device can successfully decode the PUSCH transmitted based on the OCC sequence, thereby not only achieving OCC multiplexing transmission of the PUSCH, but also successfully achieving frequency hopping of the PUSCH, thereby not only achieving uplink capacity enhancement, but also reducing transmission interference and ensuring link transmission performance. In the above embodiments, a method for a terminal to specifically determine frequency hopping related parameters and / or OCC multiplexing related parameters is provided, so that the terminal can successfully determine the frequency hopping related parameters and / or the OCC multiplexing related parameters. Thus, the terminal can perform frequency hopping on the PUSCH based on the frequency hopping related parameters, and simultaneously perform OCC multiplexing transmission on the PUSCH based on the OCC multiplexing related parameters, thereby achieving frequency hopping transmission of the PUSCH and OCC multiplexing transmission of the PUSCH, ensuring uplink capacity enhancement, and reducing transmission interference and ensuring link transmission performance.

[0544] In the present embodiment or embodiment, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other embodiments.

[0545] The following is an exemplary introduction to the above-mentioned method.

[0546] As shown in FIG. 1B, assuming that the OCC sequence with a length of 4 is covered on 4 time domain resource units, one prerequisite for receiving end to solve OCC multiplexing is that the channels passed by the 4 time domain resource units are the same.

[0547] PUSCH supports frequency hopping, as follows:

[0548] For single PUSCH transmission, intra-slot frequency hopping is supported;

[0549] For TBoMS and PUSCH repetition type A, intra-slot frequency hopping and inter-slot frequency hopping are supported;

[0550] ● For PUSCH repetition type B, then support frequency hopping between nominal repetitions with inter-slot frequency hopping.

[0551] One issue to be considered is that if frequency hopping occurs within OCC-length time domain resource units, the above premise assumption is no longer met, which will make the receiving end unable to correctly decode the PUSCH. Therefore, it is necessary to consider redesigning the frequency hopping mechanism when time-domain OCC multiplexing is used.

[0552] The method of the present disclosure is used to solve the above technical problems, and the embodiments of the present disclosure include the following contents:

[0553] ■Direction 1: Do not support enabling time-domain OCC multiplexing and frequency hopping at the same time

[0554] ●Opt.1: If time-domain OCC multiplexing related parameters are configured, or if time-domain OCC multiplexing is enabled, the terminal no longer expects to receive at least one of the following RRC configuration parameters:

[0555] -frequencyhopping

[0556] -frequencyhoppingDCI-0-1

[0557] -frequencyhoppingDCI-0-2

[0558] ●Opt.2: If time-domain OCC multiplexing related parameters are configured, or if time-domain OCC multiplexing is performed, the terminal no longer expects the FH flag field in the scheduling DCI of the related PUSCH channel to be set to 1.

[0559] ■Direction 2: Support enabling time-domain OCC multiplexing and frequency hopping at the same time

[0560] ●Case 1: Single-slot PUSCH transmission with symbol-level occ spreading

[0561] - Point 1: The terminal performs single-slot PUSCH transmission based on symbol-level OCC spreading

[0562] - Point 2: In response to receiving the gNB’s configuration parameters frequencyhopping, frequencyhoppingDCI-0-1, or frequencyhoppingDCI-0-2; and, or, receiving the FH flag in DCI set to 1, the terminal performs intra-slot frequency hopping

[0563] - Point 3: Based on the length of time domain per hop, determine the OCC length, for example, need to make sure the length of time domain per hop can be divided by the OCC length. At the same time, meet the following constraint relationship: the number of symbols of symbol spreading is less than or equal to the number of symbols within a hop. That is, the terminal does not expect to perform symbol spreading within the OCC-length time domain units within which frequency hopping occurs.

[0564] - Point 4: Based on point 3, the length of time domain symbols does not include symbols occupied by DMRS

[0565] • Case 2: multi-slot PUSCH transmission

[0566] - Symbol-level OCC spreading

[0567] o Intra-slot frequency hopping:

[0568] o Opt.1: For PUSCH repetition type A and TBoMS PUSCH, the terminal does not expect to be configured to intra-slot frequency hopping

[0569] o Opt.2: For PUSCH repetition type A and TBoMS PUSCH, intra-slot frequency hopping can be turned on, in the same way as direction 2---case 1

[0570] o Inter-slot / repetition frequency hopping:

[0571] o In this way, OCC length is determined based on the number of symbols for PUSCH transmission within per slot / repetition, e.g. the number of time-domain symbols for PUSCH transmission within each slot needs to be divisible by OCC length. The terminal does not expect OCC-length time-domain units with symbol spreading to span one slot / nominal repetition

[0572] o The time-domain symbol length does not contain the symbols occupied by DMRS

[0573] - Slot-level OCC multiplexing

[0574] o Opt.1: In this way, for PUSCH repetition type A and TBoMS PUSCH, only intra-slot frequency hopping is supported.

[0575] o For example, for PUSCH repetition type A and / or TBoMS PUSCH, the terminal does not expect to perform inter-slot frequency hopping while performing slot-level OCC multiplexing

[0576] o Opt.2: Allow the terminal to perform inter-slot / repetition frequency hopping

[0577] o Way 1: Redefine the time-domain length of each hop

[0578] ■Point 1: In this way, the time-domain length of each hop is determined based on the OCC length. The following constraint relationship is satisfied: mod(time-domain length of each hop, OCC length) = 0

[0579] ■Point 2: The time-domain length occupied by each hop can be determined in at least one of the following ways:

[0580] ■Configured / indicated directly by the base station, e.g. the number of slots or the number of repetitions for each hop is directly indicated by the gNB

[0581] ■Determine the number of slots per hop or the number of nominal repetitions per hop based on the gNB configured / indicated parameters and the protocol pre-defined rules. For example: The time-domain length per hop = N*OCC length, where N can be configured or indicated by gNB, N can be indicated by codepoint, index of set, or bitmap, etc.

[0582] Or determined by the protocol pre-defined rules, for example: The time-domain length per hop = occ length, The time-domain length per hop = occ length*2, etc.

[0583] o Way 2: Based on the legacy inter-slot / repetition frequency hopping mechanism, determine the slot-level OCC multiplexing pattern

[0584] ■Point 1: Determine the block length, each block covers the same value of one occ sequence on different slots / nominal repetitions within the block, the basic time unit of the block is slot / nominal repetition. Frequency hopping can be performed between different slots / repetitions within a block

[0585] ■Point 2: The same frequency hopping is used between each occ-length block

[0586] ■Point 3: The block length satisfies the following constraint relationship:

[0587] ■mod(the number of slots or the number of nominal repetitions within a block, 2) = 0, that is, the number of slots or the number of nominal repetitions within a block is an integer multiple of 2

[0588] ■Block length*OCC length = the number of repetitions or the number of slots

[0589] ■Point 4: The block length is determined by the gNB configured / indicated parameters or by the protocol pre-defined rules, for example: block length = (the number of repetitions or the number of slots) / OCC length, or block length = 2

[0590] Point 5: the slot number, for PUSCH repetition type A, is the repetition number, which can be the number of consecutive slots (available slot counting not on) or the number of available slots (available slot counting on); for TBoMS, is the number of available slots occupied by one TB transmission. In addition, all methods (including Direction 1 and Direction 2) can also be applicable to TBoMS with repetitions, in which case the slot number is N*M available slots, where N is the repetition number and M is the number of slots occupied by one TBoMS transmission, or vice versa.

[0591] Embodiments of the present disclosure also propose an apparatus for implementing any of the above methods, for example, an apparatus comprising units or modules for implementing the steps performed by the terminal in any of the above methods.
