[0070] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0071] Orthogonal sequences (such as orthogonal cover code (OCC) sequences) can provide orthogonality between multiple channels; accordingly, uplink transmission based on orthogonal sequences can provide better orthogonality of data transmission for uplink transmission in NTN scenarios, thereby improving the capacity of the communication system.

[0072] However, in the related art, it is impossible to support an indication method (which can also be understood as a configuration method) regarding an orthogonal sequence, and thus the multiplexing and transmission of an uplink PUSCH based on an orthogonal sequence is not supported.

[0073] Based on this, in various embodiments of the present application, the network side introduces indication information about the sequence (such as an orthogonal sequence) so that the terminal can know the sequence used for the uplink transmission. In this way, better orthogonality of data transmission can be provided for the uplink transmission, thereby improving the capacity of the communication system.

[0074] The present application embodiment provides an information transmission method, such as Figure 1 As shown, applied to a terminal, the method includes:

[0075] Step 101: Receive first information, where the first information is used to indicate a first sequence used for uplink transmission by the terminal.

[0076] In actual application, the terminal may be referred to as user equipment (UE) or user, etc. The embodiment of the present application does not limit the name of the terminal, as long as its function is realized. In addition, the first sequence may specifically include one or more orthogonal sequences, where the orthogonal sequence may include an OCC sequence. The embodiment of the present application does not limit the type and quantity of the first sequence, as long as its function is realized.

[0077] In actual application, in step 101, the terminal receives the first information, which can be understood as the terminal receiving the first information sent (can also be understood as configuration or indication or transmission). Specifically, the terminal can receive the first information sent by a network device (specifically, a base station); wherein the first information can be called indication information for indicating the first sequence, and of course, it can also be called configuration information for indicating the first sequence, which is not limited in this embodiment of the present application.

[0078] Here, in order to enable the terminal to determine the first sequence actually used for uplink transmission (such as PUSCH or PUCCH), the first information may be an index of the first sequence (which may be expressed as index in English), and at the same time, information related to the length of the first sequence may be indicated by other information; in this case, the first information may include the index of the first sequence. The terminal receives the first information and / or other information, which may be the first information and / or other information received and sent (which may also be understood as configuration or indication or transmission); specifically, the terminal may receive the first information and / or other information sent by a network device (specifically, a base station).

[0079] Based on this, in one embodiment, the method may further include:

[0080] Second information is received, where the second information is used to indicate a sequence length and / or a number of multiplexed users associated with the first sequence.

[0081] Among them, in actual application, when the first sequence is jointly indicated by the first information and the second information, the first information (for example, the first information is sent using a specific field (expressed as field in English)) can be sent through downlink control information (DCI, Downlink Control Information) signaling; the second information can be sent through radio resource control (RRC, Radio Resource Control) signaling; of course, the first information and the second information can also be sent separately through RRC signaling, which is not limited to this in the embodiment of the present application.

[0082] In actual application, when the second information indicates a sequence length associated with the first sequence, the terminal can determine multiple first sequences based on the sequence length, and then determine the first sequence from the multiple first sequences based on the index of the first sequence; wherein, when the first sequence includes an OCC, the sequence length can be the sequence length of the OCC (which can be expressed as OCC Length in English).

[0083] Exemplarily, assume that the length of the first sequence is 2; in this case, the terminal can determine two first sequences, namely, first sequence 1 (specifically {+1, +1}) and first sequence 2 (specifically {+1, -1}); based on the index of the first sequence (which can be expressed as index = 0 or 1), and select the first sequence 1 from the two first sequences.

[0084] In addition, when the length of the first sequence is 2, it means that the terminal can perform multiplexing transmission of 2 users during uplink transmission.

[0085] Exemplarily, assuming that the length of the first sequence is 4, in this case, the terminal can determine 4 first sequences, namely, first sequence 1 (specifically {+1, +1, +1, +1}), first sequence 2 (specifically {+1, -1, +1, -1}), first sequence 3 (specifically {+1, +1, -1, -1}) and first sequence 4 (specifically {+1, -1, -1, +1}); based on the index of the first sequence (for example, it can be expressed as index = 0, 1, 2 or 3), the first sequence is selected from the 4 first sequences.

[0086] In addition, when the length of the first sequence is 4, it means that the terminal can perform multiplexing transmission of 4 users during uplink transmission.

[0087] Exemplarily, it is assumed that the length of the first sequence is 8; in this case, the terminal can determine 8 first sequences, namely, first sequence 1 (specifically {+1, +1, +1, +1, +1, +1, +1, +1}), first sequence 2 (specifically {+1, -1, +1, -1, +1, -1, +1, -1}), first sequence 3 (specifically {+1, +1, -1, -1, +1, +1, -1, -1}), first sequence 4 (specifically {+1, -1, -1, +1, +1, -1, -1, +1}), first sequence 5 (specifically {+1, +1, +1, +1, -1, -1, -1}), first sequence 6 (specifically {+1, -1, +1, -1, -1, +1, -1, +1}), first sequence 7 (specifically {+1, +1, -1, -1, -1, +1, +1}) and first sequence 8 (specifically {+1, -1, -1, +1, -1, +1, +1, -1}), and select the first sequence from the 8 first sequences.

[0088] In addition, when the length of the first sequence is 8, it means that the terminal can perform multiplexing transmission for 8 users during uplink transmission.

[0089] Exemplarily, it is assumed that the length of the first sequence is 16; in this case, the terminal can determine 16 first sequences, namely, first sequence 1 (specifically {+1, +1, +1, +1, +1, +1, +1, +1, +1, +1, +1, +1, +1, +1, +1, +1}), first sequence 2 (specifically {+1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1}), first sequence 3 (specifically {+1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1}), first sequence 4 (specifically {+1, -1, -1, +1, + The first sequence 1 (specifically {+1, +1, +1, +1, -1, -1, +1, +1, -1, -1, +1, +1, -1, -1, +1}), the first sequence 2 (specifically {+1, +1, +1, +1, -1, -1, -1, +1, +1, +1, -1, -1, -1, +1}), the first sequence 3 (specifically {+1, +1, +1, -1, -1, +1, +1, -1, +1, +1, -1, +1, -1, +1}), the first sequence 4 (specifically {+1, +1, +1, -1, -1, +1, +1, -1, +1, +1, -1, +1, -1, +1}), the first sequence 5 (specifically {+1, +1, +1, +1, -1, -1, -1, +1, +1, +1, -1, -1, -1, +1}), the first sequence 6 (specifically {+1, -1, +1, -1, +1, -1, +1, +1, -1, +1, -1, +1, -1, +1}), the first sequence 7 (specifically {+1, +1, -1, -1, +1, +1, -1, +1, +1, -1, +1, -1, +1, -1, +1}), the first sequence 8 (specifically {+1, The first sequence 11 (specifically {+1, +1, -1, +1, -1, +1, -1, -1, +1, -1, +1}), the first sequence 12 (specifically {+1, +1, +1, +1, +1, -1, -1, -1, +1, -1, +1}), the first sequence 13 (specifically {+1, +1, +1, +1, -1, -1, +1, -1, +1, -1, +1}), the first sequence 14 (specifically {+1, +1, +1, +1, -1, -1, +1, -1, +1, The first sequence 14 (specifically {+1, +1, +1, -1, -1, +1, -1, +1, -1, +1, +1, -1, +1, -1}), the first sequence 15 (specifically {+1, +1, -1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1}) and the first sequence 16 (specifically {+1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1,+1, -1, +1, -1}), and select the first sequence from the 16 first sequences. ,

[0090] In addition, when the length of the first sequence is 16, it means that the terminal can perform multiplexing transmission for 16 users during uplink transmission.

[0091] In actual application, when the second information indicates the number of multiplexed users associated with the first sequence, the terminal may determine the sequence length based on the number of multiplexed users, and further determine the first sequence based on the index of the first sequence.

[0092] Exemplarily, assuming that the number of multiplexed users of the first sequence is 4, the sequence length representing the first sequence is 4; in this case, the terminal can determine 4 first sequences, namely, first sequence 1 (specifically {+1, +1, +1, +1}), first sequence 2 (specifically {+1, -1, +1, -1}), first sequence 3 (specifically {+1, +1, -1, -1}) and first sequence 4 (specifically {+1, -1, -1, +1}); based on the index of the first sequence (for example, it can be expressed as index = 0, 1, 2 or 3), the first sequence is selected from the 4 first sequences.

[0093] In actual application, in order to enable the terminal to determine the first sequence used for actual transmission, the first information may also indicate the index of the first sequence and / or information related to the length of the first sequence.

[0094] Specifically, in one embodiment, the first information includes at least one of the following (which can also be understood as one or more):

[0095] a sequence length and / or a number of multiplexed users associated with the first sequence;

[0096] An index of the first sequence.

[0097] Wherein, in actual application, when the first sequence is indicated only by the first information, the first information sent may be received through DCI signaling. That is, in actual application, when the first sequence is indicated only by the first information, the first information may be sent (also understood as transmission or bearing) through DCI signaling. Specifically, the terminal may receive the first information sent by the network device.

[0098] In actual application, when the first information includes a sequence length associated with the first sequence, the terminal may determine multiple first sequences based on the sequence length, and determine the first sequence from the multiple first sequences using a preconfigured rule; when the first information includes the number of multiplexed users associated with the first sequence, the terminal may determine the sequence length based on the number of multiplexed users, determine multiple first sequences based on the sequence length, and then determine the first sequence from the multiple first sequences using a default rule.

[0099] Exemplarily, in the case where the first information is set in the first field in the DCI signaling, if the sequence length is 2, the terminal can determine that the length of the first field is 1 bit (which can be expressed as bit in English), and 0 represents the first sequence 1 with a sequence length of 2, and 1 represents the first sequence 2 with a sequence length of 2; if the sequence length is 4, the terminal can determine that the length of the first field is 2 bits, and 0 represents the first sequence 1 with a sequence length of 4, 1 represents the first sequence 2 with a sequence length of 4, 2 represents the first sequence 3 with a sequence length of 4, and 3 represents the first sequence 4 with a sequence length of 4; if the sequence length is 8, the terminal can determine that the length of the first field is 3 bits, and 0 represents the first sequence 1 with a sequence length of 8, 1 represents the first sequence 2 with a sequence length of 8, 2 represents the first sequence 3 with a sequence length of 8, 3 represents the first sequence 4 with a sequence length of 8, 4 represents the first sequence 5 with a sequence length of 8, 5 represents the first sequence 6 with a sequence length of 8, 6 represents the first sequence 7 with a sequence length of 8, and 7 represents the first sequence 8 with a sequence length of 8; if the sequence length is 16, the terminal can determine that the length of the first field is 4 bits, and 0 to 15 respectively represent 16 first sequences with a length of 16. After determining multiple first sequences, the terminal can select the first sequence based on a preconfigured rule (such as selecting a sequence with an index of 1).

[0100] In addition, in a case where the first information includes an index of the first sequence, the terminal may determine the first sequence based on the index of the first sequence; in a case where the first information includes an index of the first sequence and a sequence length associated with the first sequence, the terminal may determine multiple first sequences based on the sequence length, and determine the first sequence based on the index of the first sequence; in a case where the first information includes an index of the first sequence and a number of multiplexed users associated with the first sequence, the terminal may determine the number of sequences based on the number of multiplexed users, thereby determining multiple first sequences, and determine the first sequence based on the index of the first sequence.

[0101] In actual application, since the relevant uplink transmission scheme (such as discrete Fourier transform (DFT)-s-orthogonal frequency division multiplexing (OFDM), DFT-s-OFDM) supports transmission of a single antenna port (expressed as port in English), the first sequence can also be indicated by the antenna port.

[0102] Based on this, in one embodiment, the first information is used to indicate an antenna port of the terminal, and the antenna port is associated with the first sequence; the method may also include:

[0103] The first sequence is determined according to a first association relationship, where the first association relationship includes a correspondence between one or more antenna ports and one or more sequences.

[0104] In actual application, the first association relationship can be called a first corresponding relationship, a first mapping, a first association or a first relationship, and the first association relationship can include an association relationship, a mapping relationship or a corresponding relationship between one or more antenna ports and one or more sequences (specifically, the indexes of one or more sequences).

[0105] In addition, the antenna port of the terminal can be understood as one or more antenna ports supported by the terminal. The antenna port can also be called a DMRS port. The number of antenna ports can be associated with the DMRS symbol (symbol in English) length (expressed as max Length in English), for example, when the DMRS symbol length is 1, the terminal can support 4 antenna ports.

[0106] In the related art, the terminal cannot know the correspondence between the antenna port and the sequence. If the sequence is matched according to the order of the antenna port, the terminal cannot determine its own antenna port, such as antenna port 1 or antenna port 2 among two antenna ports, because it does not know the antenna ports or sequences of other terminals.

[0107] To address the above problem, the first association relationship may be configured through signaling (such as RRC signaling).

[0108] Based on this, in one embodiment, the method may further include:

[0109] receiving third information, wherein the third information includes the first association relationship;

[0110] In actual application, the terminal can receive RRC signaling, and the RRC signaling includes the third information. Specifically, the terminal can receive the third information sent (can also be understood as configuration or indication or transmission) by the network device (specifically, it can be a base station). Exemplarily, when the terminal supports transmission of 4 antenna ports (port0, port1, port2 and port3 respectively), and the sequence length is 2, the 4 antenna ports and two sequences with a sequence length of 2 (sequence 1 and sequence 2 respectively) can be associated to generate the first association relationship; specifically, port0 is associated with sequence 1 with an index of 0 (which can be expressed as occ index=0), and port1 is associated with sequence 2 with an index of 1 (which can be expressed as occindex=1).

[0111] In actual application, the first association relationship may also be configured for the terminal in a predefined manner; that is, the first association relationship may be predefined, or may be understood to be determined based on a predefined rule.

[0112] For example, assuming that the DMRS symbol length is 1 and the sequence length is 2, it can be determined that the terminal supports 4 antenna ports, which are represented as port0, port1, port2 and port3. Considering that port0 and port1 usually adopt the orthogonal method of code division, there will be certain interference between them, and different resource elements (RE, Resource Element) or carriers are used for mapping or transmission between port0, port1 and port2, port3. Therefore, it can be determined that the orthogonality between port0, port1 and port2, port3 is better, and interference can also be avoided; wherein, the corresponding relationship between each RE and port is as follows: Figure 2As shown, port0 and port1 are mapped using RE0, 2, 4, 6, 8 and 10 (it can also be understood that port0 and port1 correspond to the resources of RE0, 2, 4, 6, 8 and 10), that is, port0 and port1 share or use the same RE or physical resource, and are distinguished by different sequences; port2 and port3 are mapped using RE1, 3, 5, 7, 9, 11 (it can also be understood that port2 and port3 correspond to the resources of RE1, 3, 5, 7, 9, 11), that is, port2 and port3 share or use the same RE or physical resource, and are distinguished by different sequences. In this case, port 0, port 1, port 2, port 3 and two sequences with a sequence length of 2 (which can be expressed as sequence 1 and sequence 2) can be associated to achieve the predefinition of the first association relationship; wherein port 0 and port 1 can be associated with sequence 1, and port 2 and port 3 can be associated with sequence 2; or, port 0 and port 2 can be associated with sequence 1 and sequence 2 respectively; or, port 1 and port 3 can be associated with sequence 1 and sequence 2 respectively.

[0113] Exemplarily, assuming that the first sequence is an OCC sequence, and when the antenna port indicated by the first information is port0 or port1, the terminal can determine that the first sequence used for PUSCH transmission is OCC sequence 1 based on the first association relationship; when the antenna port indicated by the first information is port2 or port3, the terminal can determine that the first sequence used for PUSCH transmission is OCC sequence 2 based on the first association relationship.

[0114] In addition, when the DMRS symbol length is 1 and the sequence length is 4, the terminal can support 4 antenna ports, which are respectively represented as port0, port1, port2 and port3. In this case, port 0, port1, port 2 and port3 are respectively associated with four sequences with a sequence length of 4 (which can be represented as sequence 1, sequence 2, sequence 3 and sequence 4), that is, port 0 is associated with sequence 1, port 1 is associated with sequence 2, port 2 is associated with sequence 3, and port 3 is associated with sequence 4.

[0115] Exemplarily, assuming that the first sequence is an OCC sequence, when the antenna port indicated by the first information is port0, the terminal can determine that the first sequence used for PUSCH transmission is OCC sequence 1 according to the first association relationship; when the antenna port indicated by the first information is port1, the terminal can determine that the first sequence used for PUSCH transmission is OCC sequence 2 according to the first association relationship; when the antenna port indicated by the first information is port2, the terminal can determine that the first sequence used for PUSCH transmission is OCC sequence 3 according to the first association relationship; when the antenna port indicated by the first information is port3, the terminal can determine that the first sequence used for PUSCH transmission is OCC sequence 4 according to the first association relationship.

[0116] In actual application, when the DMRS symbol length is 2, the terminal can support 8 antenna ports, which are respectively represented as port0, port1, port2, port3, port4, port5, port6 ​​and port7; wherein the corresponding relationship between each RE and the antenna port is as follows: Figure 3 As shown, port0, port1, port4 and port5 can be mapped with RE0, 2, 4, 6, 8 and 10 (it can also be understood that port0, port1, port4 and port5 correspond to the resources of RE0, 2, 4, 6, 8 and 10), that is, port0, port1, port4 and port5 share or use the same RE or physical resources, and are distinguished by different sequences (such as FD-OCC and TD-OCC); port2, port3, port6 ​​and port7 are mapped with RE1, 3, 5, 7, 9, 11 (it can also be understood that port2, port3, port6 ​​and port7 correspond to the resources of RE1, 3, 5, 7, 9, 11), that is, port2, port3, port6 ​​and port7 share or use the same RE or physical resources, and are distinguished by different sequences (such as FD-OCC and TD-OCC).

[0117] Here, when the DMRS symbol length is 2 and the sequence length is 2, the terminal can support 8 antenna ports. For one DMRS symbol (which can be expressed as front loaded DMRS in English), 4 antenna ports among the 8 antenna ports are associated with two sequences with a sequence length of 2 to achieve the predefinition of the first association relationship, that is, port 0 and port 1 are associated with sequence 1, and port 2 and port 3 are associated with sequence 2. For two DMRS symbols, two sequences with a sequence length of 2 among the 8 antenna ports can be associated, that is, port 0, port 1, port 4 and port 5 are associated with sequence 1, and port 2, port 3, port 6 and port 7 are associated with sequence 2.

[0118] In actual application, when the DMRS symbol length is 2 and the sequence length is 4, for one DMRS symbol, 4 antenna ports among the 8 antenna ports can be associated one-to-one with four sequences with a sequence length of 4. For example, port 0 is associated with sequence 1, port 1 is associated with sequence 2, port 2 is associated with sequence 3, and port 3 is associated with sequence 4; or, the antenna port is associated with a specified sequence. For two DMRS symbols, the 8 antenna ports can be associated with four sequences with a sequence length of 4, for example, port 0 and port 1 are associated with sequence 1, port 2 and port 3 are associated with sequence 2, port 4 and port 5 are associated with sequence 3, and port 6 and port 7 are associated with sequence 4. Or, the antenna port is associated with a specified sequence.

[0119] In actual application, when the DMRS symbol length is 2 and the sequence length is 8, for one DMRS symbol, 4 of the 8 antenna ports can be associated with four sequences with a sequence length of 8. For example, port 0 is associated with sequence 1, port 1 is associated with sequence 2, port 2 is associated with sequence 3, and port 3 is associated with sequence 4; or, the antenna port is associated with a specified sequence. For two DMRS symbols, the 8 antenna ports can be associated with eight sequences with a sequence length of 8 in one-to-one correspondence. For example, port 0 is associated with sequence 1, port 1 is associated with sequence 2, port 2 is associated with sequence 3, port 3 is associated with sequence 4, port 4 is associated with sequence 5, port 5 is associated with sequence 6, port 6 is associated with sequence 7, and port 7 is associated with sequence 8; or, the antenna port is associated with a specified sequence. . In this way, the pre-definition of the first association relationship is realized.

[0120] Here, the first sequence is determined, and the terminal can map (also understood as deploying or superimposing) the first sequence to the corresponding uplink transmission; wherein the mapping can be understood as multiplying, calculating or superimposing the first sequence or the element of the first sequence (which can be expressed as component in English) with the symbol or modulation symbol (also referred to as complex symbol) carried on the PUSCH or PUCCH, or spreading (which can be expressed as spread or spreadinging in English) the symbol or modulation symbol carried on the PUSCH or PUCCH.

[0121] Based on this, in one embodiment, if Figure 1 As shown, the method may also include:

[0122] Step 102: Map the first sequence to time domain resources and / or frequency domain resources of a PUSCH.

[0123] Among them, for time domain resources, when mapping, mapping can be performed with a time slot as a granularity (expressed as inter slot mapping or mapping in English), that is, the terminal can map the first sequence to a time slot of the PUSCH (such as 1, 2 or 4 time slots), or it can be mapped with a symbol as a granularity (expressed as intersymbol mapping in English), that is, the terminal can map the first sequence to a PUSCH symbol.

[0124] In actual application, the first sequence is mapped to the time slot of PUSCH, and the terminal can take N (N is an integer greater than or equal to 1) time slots as a group, and multiply or calculate (expressed as calculation in English) the REs carrying data in the N time slots with the elements of the first sequence to realize the mapping of the first sequence on the symbols of PUSCH; wherein, the elements of the first sequence can be understood as the numerical value of the weight of the first sequence multiplied by the corresponding data, symbol or complex symbol (expressed as complex-valued modulation symbols in English), for example, for the first sequence of length 4 {+1, +1, -1, -1}, +1, +1, -1, -1 can be called elements of the first sequence.

[0125] In actual application, since the first sequence needs to act on the same transmission data to ensure that the transmission superimposed with the first sequence is orthogonal, it is necessary to ensure that the REs in the PUSCH time slot carry the same content or data. Based on the repeated transmission of PUSCH scheduled by DCI, the RV will change according to the RV indicated in the DCI. In this case, the terminal can implement the mapping of the first sequence to the PUSCH time slot based on the number or value of the RV.

[0126] Specifically, in one embodiment, the elements of the first sequence are mapped to one or more time slots (also understood as at least one time slot) of a PUSCH having the same RV.

[0127] Here, in the process of mapping with time slot as the granularity, the time slot or repeated transmission (which can be expressed as repetition in English) of PUSCH can be mapped to the elements of the first sequence. Specifically, the terminal can map one or more time slots of PUSCH with the same RV to the elements of the first sequence (which can also be called spread spectrum or expansion (which can be expressed as spread in English) or calculation); or, the terminal can divide the time slots of PUSCH with the same RV into a group of PUSCH transmission groups, obtain one or more groups of PUSCH transmission groups, and map each group of PUSCH transmission groups to the elements of the first sequence respectively; or, the terminal can map one or more time slots of adjacent PUSCH with the same RV to the elements of the first sequence.

[0128] For example, Figure 4As shown, assuming that the first sequence is an OCC sequence and the sequence length is 2, the terminal can map the OCC sequence 1 (which can be expressed as {+1, +1}) with a sequence length of 2 to the two PUSCH time slots of user 1 whose RV is 0 (which can be expressed as RV=0 or RV0), that is, the first time slot of PUSCH is mapped to the first element +1 of OCC sequence 1, and the second time slot of PUSCH is mapped to the second element +1 of OCC sequence 1; the terminal can also map the {+1, +1} sequence to the 3rd and 4th time slots (that is, the two PUSCH time slots whose RV is 2 of user 1) until all indicated repeated transmission time slots are mapped.

[0129] In addition, the terminal may map an OCC sequence 2 (which may be expressed as {+1, -1}) having a sequence length of 2 to two PUSCH time slots of which the RV of user 2 is 0, that is, the first time slot of the PUSCH is mapped to the first element +1 of the OCC sequence 2, and the second time slot of the PUSCH is mapped to the second element -1 of the OCC sequence 2. The terminal may also map the {+1, -1} sequence to the third and fourth time slots (i.e., two PUSCH time slots of which the RV of user 2 is 2), until all indicated repeated transmission time slots are mapped.

[0130] In addition, the terminal may also map the elements of the first sequence to one or more time slots of a PUSCH with different RVs. Figure 5 As shown, assuming that the first sequence is an OCC sequence and the sequence length is 2, the terminal can map the OCC sequence 1 (which can be expressed as {+1, +1}) with a sequence length of 2 to the time slots of the PUSCH of user 1 with RVs of 0, 2, 3, 1 (which can be expressed as RV=0, 2, 3 and 1 or RV0, 2, 3, 1). That is, the first element +1 of the OCC sequence 1 is mapped or calculated with the 1st, 2nd, 3rd, and 4th time slots, and the second element +1 of the OCC sequence 1 is mapped or calculated with the 5th, 6th, 7th, and 8th time slots. At the same time, the OCC sequence 2 (which can be expressed as {+1, -1}) with a sequence length of 2 is mapped with the time slots of the PUSCH of user 2 with RVs of 0, 2, 3, and 1. That is, the first element +1 of the OCC sequence 2 is mapped or calculated with the 1st, 2nd, 3rd, and 4th time slots, and the second element -1 of the OCC sequence 2 is mapped or calculated with the 5th, 6th, 7th, and 8th time slots.

[0131] In actual application, the terminal may also map the first sequence to the PUSCH symbol based on the value of the RV.

[0132] Specifically, in one embodiment, the elements of the first sequence are mapped to one or more symbols (which can also be understood as at least one symbol) of a PUSCH having the same RV.

[0133] Here, in the process of mapping with symbols as granularity, the terminal may map one or more symbols (or plural symbols) of the PUSCH with elements of the first sequence.

[0134] Exemplarily, assuming that the first sequence is an OCC sequence and the sequence length is 2, the terminal can map OCC sequence 1 (which can be expressed as {+1, +1}) with a sequence length of 2 to the symbol (or complex symbol) carried by the PUSCH with an RV of 0 of terminal 1; at the same time, map OCC sequence 2 (which can be expressed as {+1, -1}) with a sequence length of 2 to the symbol (or complex symbol) carried by the PUSCH with an RV of 0 of terminal 2. The symbols (or complex symbols) carried by the PUSCH mapped with the OCC sequence carry the same content or information. Alternatively, the symbol carried by the PUSCH mapped with the first element (sequence length is 2) in the OCC sequence is the same as the symbol carried by the PUSCH mapped with the second element (sequence length is 2) in the OCC sequence.

[0135] In actual application, in the process of mapping with symbol as granularity, the terminal may map the first sequence to non-DMRS symbols of PUSCH, and the non-DMRS symbols may be understood as symbols not used for DMRS. The terminal may also map the first sequence to all symbols of PUSCH.

[0136] In one embodiment, mapping the first sequence to a frequency domain resource or RE of a PUSCH includes:

[0137] The elements of the first sequence are mapped to the data or information carried by the PUSCH in the frequency domain.

[0138] In actual application, on the frequency domain resources of PUSCH, each physical resource block (PRB, Physical Resource Block) or each carrier may use the same first sequence.

[0139] In actual application, the terminal may map and / or calculate the elements of the first sequence and the data or information carried by the PUSCH in the frequency domain based on the subcarrier quantity information, subcarrier identification information, a first factor (also referred to as a spreading factor), and PUSCH symbol-related information in the frequency domain; wherein the following formula may be used for mapping and / or calculation:

[0140]

[0141] Among them, M SC Expressed as the number of subcarriers in the frequency domain; N SF is represented as a first factor, which is associated with the sequence length of the first sequence; k is represented as a subcarrier identifier (i.e., the number of the subcarrier, which can also be called the second label), and the value of k is [0, M SC -1]; l represents the position of the PUSCH symbol (which can also be understood as the lth symbol or the third number), the value of l is [0, L], L is the maximum number of symbols or the maximum number; y represents the data or information carried after frequency domain mapping; w n Represented as the first sequence, w n (x) represents the element of the first sequence.

[0142] Here, in the process of mapping based on formula (1), the subcarrier identifiers can be incremented in the frequency domain (which can be expressed in increasing order of in English), and then mapped in a manner of increasing l or symbols.

[0143] For example, it is assumed that the sequence length of the first sequence is 4 (ie, N SF =4), there are 4 first sequences, namely first sequence 1 (specifically {+1, +1, +1, +1}), first sequence 2 (specifically {+1, -1, +1, -1}), first sequence 3 (specifically {+1, +1, -1, -1}) and first sequence 4 (specifically {+1, -1, -1, +1}). When n is 0, the corresponding first sequence is the first sequence 1, and w0(0) is +1, w0(1) is +1, w1(2) is +1 and w0(3) is +1; when n is 1, the corresponding first sequence is the first sequence 2, and w1(0) is +1, w1(1) is -j, w1(2) is -1 and w1(3) is +j; when n is 2, the corresponding first sequence is the first sequence 3, and w2(0) is +1, w2(1) is -1, w2(2) is +1 and w2(3) is -1; when n is 3, the corresponding first sequence is the first sequence 4, and w3(0) is +1, w3(1) is +j, w3(2) is -1 and w3(3) is -j. When M SC When l=12 and l=0, the value range of k is [0,11], which can determine the position of the 12 subcarriers corresponding to the data carried on the first symbol, that is, y(l*M SC +k) can be expressed as:

[0144]

[0145] When k = 0, y(k) = w n (0)*d(0); when k=1, y(k)=wn (0)*d(1); when k=2, y(k)=w n (0)*d(2); when k=3, y(k)=w n (1)*d(0); when k=4, y(k)=w n (1)*d(1); when k=5, y(k)=w n (1)*d(2); when k=6, y(k)=w n (2)*d(0); when k=7, y(k)=w n (2)*d(1); when k=8, y(k)=w n (2)*d(2); when k=9, y(k)=w n (3)*d(0); when k=10, y(k)=w n (3)*d(1); when k=11, y(k)=w n (3)*d(2).

[0146] It can be seen from the above description that the positions of the 12 subcarriers correspond to four repeated transmissions of data d(0), d(1), and d(2); the terminal can map the data d(0), d(1), and d(2) to the four elements of the first sequence respectively, or, after repeatedly transmitting the data d(0), d(1), and d(2) four times, map d(0), d(1), and d(2) to the elements or weights of the first sequence.
