[0072] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0073] Orthogonal sequences (such as orthogonal cover code (OCC) sequences) can provide orthogonality between multiple channels; correspondingly, uplink transmission based on orthogonal sequences can provide better data transmission orthogonality for uplink transmission in NTN scenarios, thereby improving the capacity of the communication system.

[0074] However, the relevant technologies do not support the indication method (which can also be understood as the configuration method) of orthogonal sequences, thus they do not support the multiplexing and transmission of uplink PUSCH based on orthogonal sequences.

[0075] Based on this, in various embodiments of this application, the network side introduces indication information about sequences (such as orthogonal sequences), enabling the terminal to know the sequence used for uplink transmission. This provides better orthogonality for uplink transmission, thereby improving the capacity of the communication system.

[0076] This application provides an information transmission method, as shown in FIG1, applied to a terminal, the method including:

[0077] Step 101: Receive first information, which is used to indicate the first sequence used by the terminal for uplink transmission.

[0078] In practical applications, the terminal can be referred to as User Equipment (UE) or simply as a user. This application embodiment does not limit the name of the terminal, as long as its function is implemented. Furthermore, the first sequence may specifically include one or more orthogonal sequences. Here, orthogonal sequences may include OCC sequences. This application embodiment does not limit the type and number of the first sequence, as long as its function is implemented.

[0079] In practical applications, in step 101, the terminal receiving the first information can be understood as the terminal receiving the first information sent (or configured, indicated, or transmitted). Specifically, the terminal can receive the first information sent by a network device (specifically, a base station). The first information can be called indication information for indicating the first sequence, or it can be called configuration information for indicating the first sequence. This application embodiment does not limit this.

[0080] Here, in order for the terminal to determine the first sequence used in the actual uplink transmission (such as PUSCH or PUCCH), the first information can be an index of the first sequence. Simultaneously, the length-related information of the first sequence can be indicated by other information; in this case, the first information can include the index of the first sequence. The terminal receiving the first information and / or other information can be receiving and sending (or configuring, indicating, or transmitting) the first information and / or other information; specifically, the terminal can receive the first information and / or other information sent by a network device (specifically, a base station).

[0081] Based on this, in one embodiment, the method may further include:

[0082] Receive second information, which indicates the sequence length and / or the number of multiplexing users associated with the first sequence.

[0083] In practical applications, when the first information and the second information jointly indicate the first sequence, the first information (e.g., sending the first information using a specific field) can be sent via Downlink Control Information (DCI) signaling; the second information can be sent via Radio Resource Control (RRC) signaling; of course, the first information and the second information can also be sent separately via RRC signaling, and this application embodiment does not limit this.

[0084] In practical applications, when the second information indicates the 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 contains an OCC, the sequence length can be the sequence length of the OCC (which can be expressed as OCC Length in English).

[0085] For example, suppose 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 represented as index = 0 or 1), and select first sequence 1 from the two first sequences.

[0086] In addition, when the length of the first sequence is 2, it means that the terminal can perform multiplexing transmission for 2 users during uplink transmission.

[0087] For example, assuming 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}); and select the first sequence from the 4 first sequences based on the index of the first sequence (for example, it can be represented as index = 0, 1, 2, or 3).

[0088] In addition, when the length of the first sequence is 4, it means that the terminal can perform multiplexing transmission for 4 users during uplink transmission.

[0089] For example, assuming 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}), and first sequence 4 (specifically {+1, -1, -1, +1, +1, -1}). The first sequence is selected from the eight first sequences: 5 (specifically {+1, +1, +1, +1, -1, -1, -1, -1}), 6 (specifically {+1, -1, +1, -1, -1, +1, -1, +1}), 7 (specifically {+1, +1, -1, -1, -1, -1, +1, +1}), and 8 (specifically {+1, -1, -1, +1, -1, +1, +1, +1, -1}).

[0090] 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.

[0091] For example, assuming 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}), and first sequence 4 (specifically {+1, -1, -1, + ... The first sequence is {1, -1, -1, +1, +1, +1, -1, -1, +1, +1, -1, +1}, the first sequence is 5 (specifically {+1, +1, +1, +1, -1, -1, -1, -1, +1, +1, +1, +1, -1, -1, -1}), the first sequence is 6 (specifically {+1, -1, +1, -1, -1, +1, -1, +1, +1, -1, +1, -1, -1, +1, -1, +1, -1}), the first sequence is 7 (specifically {+1, +1, -1, -1, -1, -1, +1, +1, +1, +1, -1, -1, -1, +1, -1}), the first sequence is 8 (specifically {+1, -1, -1, +1, -1, +1, +1, +1, -1, -1}). The first sequence 9 (specifically {+1, +1, +1, +1, +1, +1, +1, +1, +1, +1, -1, -1, -1, -1, -1, -1, -1}), the first sequence 10 (specifically {+1, -1, +1, -1, +1, -1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1, -1, +1}), the first sequence 11 (specifically {+1, +1, -1, -1, +1, +1, -1, -1, -1, -1, +1, +1, -1, -1, +1, +1}), the first sequence 12 (specifically {+1, -1, -1, +1, +1, -1, -1, + ... The first sequence 13 (specifically {+1, +1, +1, +1, -1, -1, -1, -1, -1, -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, +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, +1, +1, -1}), and the first sequence 16 (specifically {+1, -1, -1, +1, -1, +1, +1, +1, - ...+1, -1, +1, -1}), and select the first sequence from the 16 first sequences.

[0092] 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.

[0093] In practical applications, when the second information indicates the number of multiplexed users associated with the first sequence, the terminal can determine the sequence length based on the number of multiplexed users, and then determine the first sequence based on the index of the first sequence.

[0094] For example, assuming the number of reused users for the first sequence is 4, representing the sequence 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}); and select the first sequence from the 4 first sequences based on the index of the first sequence (for example, it can be represented as index = 0, 1, 2, or 3).

[0095] In practical applications, in order for the terminal to determine the first sequence used in the actual transmission, the first information can also indicate the index of the first sequence and / or the length-related information of the first sequence.

[0096] Specifically, in one embodiment, the first information includes at least one of the following (which may also be understood as one or more):

[0097] The sequence length and / or the number of multiplexing users associated with the first sequence;

[0098] The index of the first sequence.

[0099] In practical applications, when the first sequence is indicated solely by the first information, the first information can be received via DCI signaling. In other words, in practical applications, when the first sequence is indicated solely by the first information, the first information can be sent via DCI signaling (which can also be understood as transmission or bearer). Specifically, the terminal can receive the first information sent by the network device.

[0100] In practical applications, when the first information includes the sequence length associated with the first sequence, the terminal can determine multiple first sequences based on the sequence length and use pre-configured rules to determine the first sequence from the multiple first sequences; when the first information includes the number of reused users associated with the first sequence, the terminal can determine the sequence length based on the number of reused users and determine multiple first sequences based on the sequence length, and then use default rules to determine the first sequence from the multiple first sequences.

[0101] For example, when the first information is set in the first field of the DCI signaling, if the sequence length is 2, the terminal can determine that the length of the first field is 1 bit, 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... 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 represent 16 first sequences of length 16 respectively. After determining multiple first sequences, the terminal can select the first sequence based on pre-configured rules (such as selecting the sequence with index 1).

[0102] Furthermore, if the first information includes the index of the first sequence, the terminal can determine the first sequence based on the index of the first sequence; if the first information includes the index of the first sequence and the sequence length associated with the first sequence, the terminal can determine multiple first sequences based on the sequence length and determine the first sequence based on the index of the first sequence; if the first information includes the index of the first sequence and the number of multiplexing users associated with the first sequence, the terminal can determine the number of sequences based on the number of multiplexing users, thereby determining multiple first sequences and determining the first sequence based on the index of the first sequence.

[0103] In practical applications, since the relevant uplink transmission schemes (such as Discrete Fourier Transform (DFT)-s-Orthogonal Frequency Division Multiplexing (OFDM)) support transmission through a single antenna port, the first sequence can also be indicated through the antenna port.

[0104] Based on this, in one embodiment, the first information is used to indicate the antenna port of the terminal, the antenna port being associated with the first sequence; the method may further include:

[0105] The first sequence is determined based on a first association relationship, which includes a correspondence between one or more antenna ports and one or more sequences.

[0106] In practical applications, the first association relationship can be referred to as the first correspondence relationship, the first mapping, the first association, or the first relationship. The first association relationship can include the association relationship, mapping relationship, or correspondence relationship between one or more antenna ports and one or more sequences (specifically, the indices of one or more sequences).

[0107] Additionally, 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 related to the DMRS symbol length (max Length), for example, when the DMRS symbol length is 1, the terminal can support 4 antenna ports.

[0108] In related technologies, the terminal cannot know the correspondence between antenna ports and sequences. If the antenna ports are matched with the sequence according to their order, the terminal cannot determine its own antenna port, such as antenna port 1 or antenna port 2 out of two, because it does not know the antenna ports or sequences of other terminals.

[0109] To address the above issues, the first association relationship can be configured via signaling (such as RRC signaling).

[0110] Based on this, in one embodiment, the method may further include:

[0111] Receive third information, wherein the third information contains the first association relationship;

[0112] In practical applications, the terminal can receive RRC signaling, which includes the third information. Specifically, the terminal can receive the third information sent (or configured, indicated, or transmitted) by the network device (specifically, a base station). For example, when the terminal supports transmission through four antenna ports (port0, port1, port2, and port3) and the sequence length is 2, the four antenna ports can be associated with two sequences of length 2 (sequence 1 and sequence 2) to generate the first association relationship; specifically, port0 is associated with sequence 1 (index 0, which can be represented as occ index = 0), and port1 is associated with sequence 2 (index 1, which can be represented as occ index = 1).

[0113] In practical applications, the first association relationship can also be configured for the terminal in a predefined manner; that is, the first association relationship can be predefined or can be understood as something that can be determined based on predefined rules.

[0114] For example, assuming the DMRS symbol length is 1 and the sequence length is 2, it can be determined that the terminal supports 4 antenna ports, represented as port0, port1, port2 and port3 respectively. Considering that ports 0 and 1 typically use code division orthogonal methods, there will be some interference between them. Since ports 0 and 1 use different resource elements (REs) or carriers for mapping or transmission with ports 2 and 3, it can be determined that the orthogonality between ports 0 and 1 and ports 2 and 3 is better, and interference can be avoided. The correspondence between each RE and port is shown in Figure 2. Ports 0 and 1 are mapped using REs 0, 2, 4, 6, 8, and 10 (which can also be understood as ports 0 and 1 corresponding to resources of REs 0, 2, 4, 6, 8, and 10), meaning ports 0 and 1 share or use the same REs or physical resources and are distinguished by different sequences. Ports 2 and 3 are mapped using REs 1, 3, 5, 7, 9, and 11 (which can also be understood as ports 2 and 3 corresponding to resources of REs 1, 3, 5, 7, 9, and 11), meaning ports 2 and 3 share or use the same REs or physical resources and are distinguished by different sequences. In this case, ports 0, 1, 2, and 3 can be associated with two sequences of length 2 (which can be represented as sequence 1 and sequence 2) to achieve the predefined association relationship. Specifically, ports 0 and 1 can be associated with sequence 1, and ports 2 and 3 can be associated with sequence 2. Alternatively, ports 0 and 2 can be associated with sequence 1 and sequence 2 respectively. Or, ports 1 and 3 can be associated with sequence 1 and sequence 2 respectively.

[0115] For example, assuming the first sequence is an OCC sequence, and 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; and if 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.

[0116] Furthermore, with a DMRS symbol length of 1 and a sequence length of 4, the terminal can support 4 antenna ports, represented as port0, port1, port2, and port3. In this case, port0, port1, port2, and port3 are respectively associated with four sequences of length 4 (which can be represented as sequence 1, sequence 2, sequence 3, and sequence 4), that is, port0 is associated with sequence 1, port1 with sequence 2, port2 with sequence 3, and port3 with sequence 4.

[0117] For example, assuming 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 based on 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 based on 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 based on the first association relationship; and 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 based on the first association relationship.

[0118] In practical applications, with a DMRS symbol length of 2, the terminal can support 8 antenna ports, represented as port0, port1, port2, port3, port4, port5, port6, and port7. The correspondence between each RE and antenna port is shown in Figure 3. Port0, port1, port4, and port5 can be mapped using RE0, 2, 4, 6, 8, and 10 (or, as understood, port0, port1, port4, and port5 correspond to the resources of RE0, 2, 4, 6, 8, and 10), i.e., port0, port1... Ports 1, 2, 3, 6, and 7 share or use the same RE or physical resources, and are distinguished by different sequences (such as FD-OCC and TD-OCC); ports 2, 3, 6, and 7 are mapped using RE1, 3, 5, 7, 9, and 11 (which can also be understood as ports 2, 3, 6, and 7 corresponding to resources of RE1, 3, 5, 7, 9, and 11).

[0119] Here, with a DMRS symbol length of 2 and a sequence length of 2, the terminal can support 8 antenna ports. For a single DMRS symbol (which can be represented as a front-loaded DMRS), 4 of the 8 antenna ports are associated with two sequences of length 2 to predefine 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, the 8 antenna ports can be associated with two sequences of length 2; 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.

[0120] In practical applications, with a DMRS symbol length of 2 and a sequence length of 4, for a single DMRS symbol, four of the eight antenna ports can be mapped one-to-one with four sequences of length 4. For example, port 0 can be associated with sequence 1, port 1 with sequence 2, port 2 with sequence 3, and port 3 with sequence 4; or, the antenna ports can be associated with a specified sequence. For two DMRS symbols, the eight antenna ports can be associated with four sequences of length 4. For example, port 0 and port 1 can be associated with sequence 1, port 2 and port 3 with sequence 2, port 4 and port 5 with sequence 3, and port 6 and port 7 with sequence 4. Alternatively, the antenna ports can be associated with a specified sequence.

[0121] In practical applications, with a DMRS symbol length of 2 and a sequence length of 8, for a single DMRS symbol, four of the eight antenna ports can be associated with four sequences of length 8. For example, port 0 can be associated with sequence 1, port 1 with sequence 2, port 2 with sequence 3, and port 3 with sequence 4; or, the antenna ports can be associated with a specified sequence. For two DMRS symbols, the eight antenna ports can be mapped one-to-one with eight sequences of length 8. For example, port 0 can be associated with sequence 1, port 1 with sequence 2, port 2 with sequence 3, port 3 with sequence 4, port 4 with sequence 5, port 5 with sequence 6, port 6 with sequence 7, and port 7 with sequence 8; or, the antenna ports can be associated with a specified sequence. This achieves the predefined first association relationship.

[0122] Here, after determining the first sequence, the terminal can map (or deploy or overlay) the first sequence to the corresponding uplink transmission; wherein, mapping can be understood as multiplying, operating or overlaying the first sequence or its elements with the symbols or modulation symbols (also known as complex symbols) carried on the PUSCH or PUCCH, or spreading (or spreading) the symbols or modulation symbols carried on the PUSCH or PUCCH.

[0123] Based on this, in one embodiment, as shown in FIG1, the method may further include:

[0124] Step 102: Map the first sequence to the time-domain and / or frequency-domain resources of PUSCH.

[0125] For time-domain resources, mapping can be performed at the time slot level (inter-slot mapping or mapping), meaning the terminal can map the first sequence to a PUSCH time slot (e.g., 1, 2, or 4 time slots), or at the symbol level (inter-symbol mapping), meaning the terminal can map the first sequence to a PUSCH symbol.

[0126] In practical applications, the first sequence is mapped to a PUSCH time slot. The terminal can group N time slots (N is an integer greater than or equal to 1) and perform multiplication or calculation (which can be expressed as calculation) on 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 the PUSCH. The elements of the first sequence can be understood as the values ​​of the weight of the first sequence multiplied by the corresponding data, symbols, or complex-valued modulation symbols. For example, for a first sequence of length 4 {+1, +1, -1, -1}, +1, +1, -1, -1 can be called the elements of the first sequence.

[0127] In practical applications, since the first sequence needs to be applied to the same transmitted data to ensure the orthogonality of the transmission of the superimposed first sequence, it is necessary to ensure that the REs in the PUSCH time slots carry the same content or data. For PUSCH repetition transmission based on DCI scheduling, the RV changes according to the RV in the DCI indication. In this case, the terminal can map the first sequence to the PUSCH time slots based on the number or value of RVs.

[0128] Specifically, in one embodiment, the elements of the first sequence are mapped to one or more time slots (or at least one time slot) of a PUSCH having the same RV.

[0129] Here, in the process of mapping at the time slot level, the time slots or repetitions of PUSCHs can be mapped to the elements of the first sequence. Specifically, the terminal can map one or more time slots of PUSCHs with the same RV to the elements of the first sequence (also known as spread spectrum or calculation); or, the terminal can divide the time slots of PUSCHs with the same RV into a group of PUSCH transmission groups, obtaining one or more groups of PUSCH transmission groups, and map each group of PUSCH transmission groups to the elements of the first sequence; or, the terminal can map one or more time slots of adjacent PUSCHs with the same RV to the elements of the first sequence.

[0130] For example, as shown in Figure 4, assuming the first sequence is an OCC sequence with a sequence length of 2, the terminal can map the OCC sequence 1 (which can be represented as {+1, +1}) with a sequence length of 2 to the two PUSCH time slots of user 1 with RV of 0 (which can be represented as RV = 0 or RV0), that is, map the first time slot of PUSCH to the first element +1 of OCC sequence 1, and map the second time slot of PUSCH to the second element +1 of OCC sequence 1; the terminal can also map the {+1, +1} sequence to the third and fourth time slots (i.e., the two PUSCH time slots of user 1 with RV of 2), until all indicated duplicate transmission time slots are mapped.

[0131] Additionally, the terminal can map the OCC sequence 2 (which can be represented as {+1, -1}) of length 2 to the two PUSCH time slots where the user's RV is 0, respectively. Specifically, it maps the first PUSCH time slot to the first element +1 of OCC sequence 2, and the second PUSCH time slot to the second element -1 of OCC sequence 2. The terminal can also map the {+1, -1} sequence to the 3rd and 4th time slots (i.e., the two PUSCH time slots where the user's RV is 2), until all indicated repetitive transmission time slots are mapped.

[0132] Additionally, the terminal can map elements of the first sequence to one or more time slots of PUSCH with different RVs. For example, as shown in FIG5, assuming the first sequence is an OCC sequence with a sequence length of 2, the terminal can map OCC sequence 1 (which can be represented as {+1, +1}) of length 2 to the time slots of PUSCH where user 1's RVs are 0, 2, 3, 1 (which can be represented as RV = 0, 2, 3, and 1 or RV 0, 2, 3, 1). That is, the first element +1 of OCC sequence 1 is mapped or operated with the 1st, 2nd, 3rd, and 4th time slots, and the second element +1 of OCC sequence 1 is mapped or operated with the 5th, 6th, 7th, and 8th time slots. Simultaneously, OCC sequence 2 (which can be represented as {+1, -1}) of length 2 is mapped to the time slots of PUSCH where user 2's RVs are 0, 2, 3, and 1. That is, the first element +1 of the OCC sequence 2 is mapped or operated with the 1st, 2nd, 3rd and 4th time slots, and the second element -1 of the OCC sequence 2 is mapped or operated with the 5th, 6th, 7th and 8th time slots.

[0133] In practical applications, the terminal can also map the first sequence to symbols of PUSCH based on the value of RV.

[0134] Specifically, in one embodiment, the elements of the first sequence are mapped to one or more symbols (or at least one symbol) of a PUSCH having the same RV.

[0135] Here, in the process of mapping at the symbol level, the terminal can map one or more symbols (or complex symbols) of PUSCH to the elements of the first sequence.

[0136] For example, assuming the first sequence is an OCC sequence with a sequence length of 2, the terminal can map the OCC sequence 1 (which can be represented as {+1, +1}) with a sequence length of 2 to the symbol (or complex symbol) carried by the PUSCH of terminal 1 with an RV of 0; simultaneously, it can map the OCC sequence 2 (which can be represented as {+1, -1}) with a sequence length of 2 to the symbol (or complex symbol) carried by the PUSCH of terminal 2 with an RV of 0. The symbol (or complex symbol) carried by the PUSCH mapped to the OCC sequence carries the same content or information. Alternatively, the symbol carried by the PUSCH mapped to the first element (sequence length of 2) in the OCC sequence can be the same as the symbol carried by the PUSCH mapped to the second element (sequence length of 2) in the OCC sequence.

[0137] In practical applications, during the symbol-level mapping process, the terminal can map the first sequence to non-DMRS symbols of the PUSCH, where non-DMRS symbols are those not used for DMRS. Alternatively, the terminal can map the first sequence to all symbols of the PUSCH.

[0138] In one embodiment, mapping the first sequence to a frequency domain resource or RE of the PUSCH includes:

[0139] The elements of the first sequence are mapped in the frequency domain to the data or information carried by the PUSCH.

[0140] In practical applications, each Physical Resource Block (PRB) or each carrier in the frequency domain of PUSCH can use the same first sequence.

[0141] In practical applications, the terminal can map and / or calculate the elements of the first sequence with the data or information carried by the PUSCH in the frequency domain based on the subcarrier number information, subcarrier identification information, the first factor (also known as the spreading factor), and the symbol-related information of the PUSCH; wherein, the following formula can be used for mapping and / or calculation:

[0142] Among them, MSC N represents the number of subcarriers in the frequency domain; SF The first factor is denoted as k, which is associated with the sequence length of the first sequence; k represents the subcarrier identifier (i.e., the subcarrier number, also known as 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 l-th symbol or the third number), and the value of l is [0, L], where 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 an element of the first sequence.

[0143] Here, in the process of mapping based on formula (1), the subcarrier identifier can be incremented in the frequency domain (which can be expressed as in increasing order of), and then the mapping is performed in the manner of incrementing l or symbol.

[0144] For example, suppose the length of the first sequence is 4 (i.e., 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 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 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 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 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 k is 12 and l = 0, the range of k is [0, 11]. This allows us to determine the position of the 12 subcarriers corresponding to the data carried on the first symbol, i.e., y(l*M) SC +k) can be represented as:

[0145] Where, when k = 0, y(k) = w n (0)*d(0); When k=1, y(k)=w n (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] As can be seen from the above description, the positions of the 12 subcarriers correspond to the 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, or, after the data d(0), d(1), and d(2) are transmitted four times, map d(0), d(1), and d(2) to the elements or weights of the first sequence.
