[0056] UCI and PUSCH multiplexing transmission in NR system

[0057] In the NR system, uplink PUSCH transmission supports not only DFT-S-OFDM waveforms but also CP-OFDM waveforms. However, the mapping rules of uplink control information (UCI) on the physical uplink shared channel (PUSCH) are the same for both waveforms.

[0058] The types of UCI information carried on PUSCH include one or more of the following: Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK), Channel State Information (CSI) Part 1, CSI Part 2, Configured Grant-UCI (CG-UCI), HARQ-ACK and CG-UCI. When the UCI information carried on PUSCH includes both HARQ-ACK and CG-UCI, HARQ-ACK and CG-UCI are jointly encoded. When the UCI information carried on PUSCH does not include both HARQ-ACK and CG-UCI, HARQ-ACK or CG-UCI, CSI Part 1 and CSI Part 2 are independently encoded. The purpose is to protect the transmission of UCI information with higher reliability requirements.

[0059] Regarding the channel coding type used, UCI is transmitted on the PUSCH using the same scheme as that used for UCI transmission on the PUCCH. That is, when the number of UCI bits is greater than or equal to 12 bits, Polar codes are used; when the number of UCI bits is less than or equal to 11 bits, short codes (channel coding of small block lengths) are used.

[0060] Because the length of the sequence after channel coding cannot meet the requirements of the total number of resource elements (REs) actually mapped, rate matching is required to adaptively adjust the channel-coded bit sequence so that it can be mapped onto all allocated REs. This process is achieved through rate matching. Rate matching for UCI transmission on the PUSCH is specifically divided into two cases: when the PUSCH carries uplink data and when the PUSCH does not carry uplink data.

[0061] After channel coding and rate matching, the UCI maps the bit sequence onto a matrix of the same size as the time and frequency domains of the physical resources occupied by the PUSCH (each mapping unit in the matrix corresponds to an RE). The number of bits mapped on each mapping unit is the number of bits corresponding to the modulation order of the modulation method. Among them, the UCI uses the same modulation method as the data part. For example, when the modulation method is Quadrature Phase Shift Keying (QPSK), 2 bits are mapped on each mapping unit; when the modulation method is 16QAM (Quadrature Amplitude Modulation), 4 bits are mapped on each mapping unit; when the modulation method is 64QAM, 6 bits are mapped on each mapping unit; when the modulation method is 256QAM, 8 bits are mapped on each mapping unit. When the waveform of the uplink PUSCH transmission is a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform, the modulation symbol obtained by modulating the bits mapped on each mapping unit is mapped to the physical resource corresponding to the mapping unit. When the waveform of the uplink PUSCH transmission is a Discrete Fourier Transform-Spread-OFDM (DFT-S-OFDM) waveform, the modulation symbol obtained by modulating the bits mapped on each mapping unit is mapped to the physical resource corresponding to the symbol.

[0062] When the number of HARQ-ACK information bits is less than or equal to 2, the number of reserved REs is first calculated based on the fact that the number of HARQ-ACK information bits is equal to 2, and REs are reserved for possible HARQ-ACK information transmission. Considering that CSI Part 1 has a relatively small number of bits and is highly important to transmit, to avoid the impact of puncturing on CSI Part 1, CSI Part 1 is prohibited from being mapped on reserved REs. Information other than CSI Part 1 (CSI Part 2 and data) can be mapped on reserved REs. If HARQ-ACK information is present, it is mapped to the reserved REs using puncturing. In addition, when there is no uplink data and the UCI information includes CSI Part 1 but not CSI Part 2, if the actually transmitted HARQ-ACK bits are less than 2 (for example, no HARQ-ACK bits or only 1 bit), it is necessary to assume that the HARQ-ACK bits are 2 bits, and the insufficient part needs to be padded to 2 bits by 0, so as to fill the reserved REs and avoid the occurrence of energy-free blank REs in PUSCH (avoiding the reserved REs from being sent), so as to ensure the low peak-to-average power ratio (PAPR) of the uplink single carrier when using the DFT-S-OFDM waveform. During mapping, if there is CSI Part 1, starting from the data symbol after the first demodulation reference signal (DMRS) symbol of PUSCH, CSI Part 1 is mapped with frequency domain priority and the reserved RE position is skipped; then if there is CSI Part 2, CSI Part 2 is mapped with frequency domain priority; then if there is an uplink shared channel (UL-SCH), UL-SCH is mapped with frequency domain priority; then if there is HARQ-ACK information, HARQ-ACK information is mapped on the reserved RE in a punctured manner.

[0063] When the number of HARQ-ACK information bits is greater than 2, both HARQ-ACK and CSI map the rate-matched bit sequence starting from the data symbol after the first DMRS of the PUSCH. During mapping, the most important signal, HARQ-ACK, is mapped immediately adjacent to the DMRS with frequency-domain priority. Then, if CSI Part 1 is present, CSI Part 1 is mapped with frequency-domain priority. Then, if CSI Part 2 is present, CSI Part 2 is mapped with frequency-domain priority. Finally, if UL-SCH (uplink data) is present, UL-SCH is mapped with frequency-domain priority.

[0064] For each type of UCI, when mapping on a certain symbol, assuming that the number of subcarriers available for UCI mapping on the symbol is N, the number of subcarriers that the UCI needs to be mapped on the symbol is M. If M is greater than or equal to N, then all of the N subcarriers are used for mapping the UCI, that is, the UCI is continuously mapped on the subcarriers of the symbol; if M is less than N, then M subcarriers among the N subcarriers are used for mapping the UCI, where the M subcarriers are distributed, equally spaced, and uniformly mapped subcarriers among the N subcarriers. As a special case, if M is less than N but M is greater than N / 2, since the number of occupied subcarriers is greater than half of the total number of available subcarriers for the symbol, then the M subcarriers are the first M subcarriers among the N subcarriers, that is, the UCI is still continuously mapped on the subcarriers of the symbol.

[0065] Figure 3 is a schematic diagram of UCI and PUSCH multiplexing transmission provided by an embodiment of the present application, which provides a schematic diagram of mapping UCI on the matrix corresponding to the time-frequency domain resources occupied by PUSCH when the DMRS mapping type is type B (Type B), the number of HARQ-ACK information bits is less than or equal to 2 bits (that is, the number of HARQ-ACK information bits is 0, 1 or 2 bits) and the number of HARQ-ACK information bits is greater than 2 bits.

[0066] PUSCH transmission in NTN system

[0067] In NTN systems, repeated transmission of the PUSCH is often used to improve uplink coverage in a cell. For example, a PUSCH is repeated N times in the time domain. Since a PUSCH needs to be repeated N times, the uplink resources occupied are N times that of a non-repeated PUSCH, resulting in a reduction in the system's uplink capacity. Therefore, in this scenario, to improve the uplink capacity of the NTN system, the PUSCH can be transmitted using orthogonal codes (also known as orthogonal cover codes, OCC) spread spectrum.

[0068] Figure 4 is an example diagram of using OCC to transmit PUSCH to improve uplink capacity involved in an embodiment of the present application, which gives an example of improving uplink capacity. In the case of not using OCC, assuming that UE1 needs to transmit TB1 four times in order to meet the uplink coverage requirement, the network device needs to allocate four resources for the TB1 of UE1 for transmission, that is, the four resources serve one terminal device. In the case of using OCC, on the four resources allocated by the network device, UE1 can use one OCC (for example, OCC1) to transmit TB1, UE2 can use one OCC (for example, OCC2) to transmit TB2, UE3 can use one OCC (for example, OCC3) to transmit TB3, and UE4 can use one OCC (for example, OCC4) to transmit TB4, that is, the four resources can serve four terminal devices, and the uplink transmissions of different terminal devices can be guaranteed to be orthogonal by different OCCs, thereby achieving the purpose of improving uplink capacity while ensuring the uplink coverage of the terminal devices.

[0069] In a communication system (such as NTN), when a terminal device uses OCC to transmit PUSCH, when the terminal device needs to multiplex UCI and PUSCH for transmission, if the multiplexing method of UCI and PUSCH in the existing system is adopted, it may affect the orthogonality of the PUSCH transmitted by the terminal device, thereby causing its PUSCH performance to be reduced.

[0070] Taking the OCC spreading unit with a symbol or time slot size of 1 PUSCH and an OCC set of {{+1, +1, +1, +1}, {+1, -1, +1, -1}, {+1, +1, -1, -1}, {+1, -1, -1, +1}} as an example, an example is given of using different OCCs for different terminal devices to perform PUSCH transmission on the same time domain and frequency domain resources.

[0071] Figure 5 is an example diagram of time-domain OCC spread spectrum involved in an embodiment of the present application; as shown in Figure 5, UE1, UE2, UE3, and UE4 are allocated the same time-domain and frequency-domain resources for PUSCH transmission. For each UE among UE1, UE2, UE3, and UE4, the PUSCH includes 12 data symbols, wherein the kth data symbol, the k+3th data symbol, the k+6th data symbol, and the k+9th data symbol in the PUSCH carry the same information, and k is 0, 1, and 2. In other words, the 0th, 3rd, 6th, and 9th symbols in the PUSCH are data symbols for repeated transmission, the 1st, 4th, 7th, and 10th symbols are data symbols for repeated transmission, and the 2nd, 5th, 8th, and 11th symbols are data symbols for repeated transmission.

[0072] The OCC used by UE1 is {+1, +1, +1, +1}, then all data symbols in the PUSCH transmitted by UE1 are scrambled with the OCC factor {+1}; the OCC used by UE2 is {+1, -1, +1, -1}, then the 0th, 1st, and 2nd data symbols in the PUSCH transmitted by UE2 are scrambled with the OCC factor {+1}, the 3rd, 4th, and 5th data symbols are scrambled with the OCC factor {-1}, the 6th, 7th, and 8th data symbols are scrambled with the OCC factor {+1}, and the 9th, 10th, and 11th data symbols are scrambled with the OCC factor {-1}; the OCC used by UE3 is {+1, +1, -1, -1}, then the 0th data symbol in the PUSCH transmitted by UE3 is scrambled with the OCC factor {+1}. The 0th, 1st, and 2nd data symbols use OCC factor {+1} scrambling, the 3rd, 4th, and 5th data symbols use OCC factor {+1} scrambling, the 6th, 7th, and 8th data symbols use OCC factor {-1} scrambling, and the 9th, 10th, and 11th data symbols use OCC factor {-1} scrambling; the OCC used by UE4 is {+1, -1, -1, +1}, then the 0th, 1st, and 2nd data symbols in the PUSCH transmitted by UE4 use OCC factor {+1} scrambling, the 3rd, 4th, and 5th data symbols use OCC factor {-1} scrambling, the 6th, 7th, and 8th data symbols use OCC factor {-1} scrambling, and the 9th, 10th, and 11th data symbols use OCC factor {+1} scrambling.

[0073] When UE1 needs to multiplex UCI transmission on PUSCH, if the UCI multiplexing method shown in Figure 5 is still used, for example, UCI information is multiplexed on the 0th data symbol, the orthogonality of UE1's PUSCH transmission using OCC is destroyed or UE1 can no longer use OCC for PUSCH transmission, resulting in a decrease in PUSCH performance or a decrease in system uplink capacity.

[0074] In this regard, the solution shown in the subsequent embodiments of this application discloses a solution for enhancing the multiplexing transmission of UCI and PUSCH to improve the performance of the terminal device when using OCC for PUSCH transmission.

[0075] Please refer to Figure 6, which shows a flowchart of an uplink transmission method provided by an embodiment of the present application. The method can be performed by a terminal device, wherein the terminal device can be a terminal device in the aforementioned network architecture or a terminal device in other network architectures, and the present application is not limited to this. The method can include at least some of the following steps:

[0076] Step 610: When the first time-frequency resource and the second time-frequency resource overlap in the time domain and the first physical uplink shared channel PUSCH is transmitted in a transmission mode corresponding to orthogonal cover code (OCC) spread spectrum, perform transmission processing.

[0077] The above-mentioned transmission processing includes one or more of the following processing: transmitting the first uplink control information UCI and the information multiplexed with the first uplink shared channel UL-SCH through the first time-frequency resource; transmitting the first UCI through the first time-frequency resource; transmitting the first UCI through the second time-frequency resource; transmitting the first UL-SCH through the first time-frequency resource; not transmitting the first UL-SCH through the first time-frequency resource; not transmitting the first UCI through the second time-frequency resource.

[0078] Among them, the first time-frequency resource is the resource allocated to the terminal device for the first PUSCH transmission, and the second time-frequency resource is the resource allocated to the terminal device for the first physical uplink control channel PUCCH transmission; the first UCI has a mapping relationship with the first PUCCH, and the first UL-SCH has a mapping relationship with the first PUSCH.

[0079] To sum up, the scheme shown in the embodiment of the present application is that when the first time-frequency resource for transmitting PUSCH overlaps with the second time-frequency resource for transmitting PUCCH, the terminal device can control the transmission of UCI corresponding to PUCCH and UL-SCH corresponding to PUSCH. Specifically, it can transmit UCI or UL-SCH, or transmit UCI and UL-SCH after multiplexing, or not transmit UCI / UL-SCH, thereby supporting the use or non-use of OCC to transmit UCI and / or UL-SCH when the first time-frequency resource and the second time-frequency resource overlap in the time domain, thereby providing a scheme for enhancing the multiplexing transmission of UCI and PUSCH, thereby improving the performance of the terminal device when using OCC for PUSCH transmission.

[0188] For example, in embodiment 1, the terminal device transmits the first UCI and / or the information multiplexed by the first UL-SCH through the first time-frequency resource, including at least one of the following steps: mapping the first bit sequence and / or the second bit sequence on the mapping unit of the first matrix; modulating the bit mapped on each mapping unit to obtain a modulation symbol; spreading each modulation symbol using the corresponding OCC factor; performing a DFT operation on the modulation symbol spread on the mapping unit in the first matrix corresponding to each symbol to obtain information to the resource corresponding to the symbol in the first time-frequency resource; transmitting the information multiplexed by the first UCI and the first UL-SCH through the first time-frequency resource; wherein the first bit sequence includes the bit sequence corresponding to the first UCI, and the second bit sequence includes the bit sequence corresponding to the first UL-SCH.

[0189] In embodiment 1, the number of rows included in the first matrix is ​​determined according to the number of subcarriers used to transmit the first UCI and the first UL-SCH in the first time-frequency resource, and the number of columns included in the first matrix is ​​determined according to the number of symbols used to transmit the first UCI and the first UL-SCH in the first time-frequency resource; or, the mapping unit of the first matrix corresponds to the RE used to transmit the first UCI and the first UL-SCH in the first time-frequency resource.

[0190] In embodiment 1, the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol.

[0191] The order of the above-mentioned spreading and DFT operations can be swapped. For example, in embodiment 2, the above-mentioned terminal device transmits the above-mentioned first UCI and / or the information multiplexed by the above-mentioned first UL-SCH through the above-mentioned first time-frequency resource, including at least one of the following steps: mapping the first bit sequence and / or the second bit sequence on the mapping unit of the first matrix; modulating the bits mapped on each mapping unit to obtain a modulation symbol; performing a DFT operation on the modulation symbol on the mapping unit in the first matrix corresponding to each symbol to obtain information to the resource corresponding to the symbol in the first time-frequency resource; spreading each symbol using the corresponding OCC factor; transmitting the information multiplexed by the first UCI and the first UL-SCH through the first time-frequency resource; wherein the first bit sequence includes the bit sequence corresponding to the first UCI, and the second bit sequence includes the bit sequence corresponding to the first UL-SCH.

[0192] In embodiment 2, the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol.

[0193] In embodiment 2, when the waveform of the uplink PUSCH transmission is a DFT-S-OFDM waveform, the terminal device maps the bit sequence corresponding to the first UCI and the bit sequence corresponding to the first UL-SCH onto a mapping unit in a first matrix determined according to the resource size used to transmit the first UCI and the first UL-SCH in the first time-frequency resource, and then modulates the bits mapped on each mapping unit to obtain a modulation symbol, spreads each modulation symbol using the corresponding OCC factor, and performs a DFT operation on the spread modulation symbol on the mapping unit corresponding to each symbol in the first matrix, obtaining information that is mapped to the physical resource corresponding to the symbol for transmission.

[0194] For another example, in Example 3, the terminal device transmits the first UCI and / or the first UL-SCH multiplexed information through the first time-frequency resource, including at least one of the following steps: mapping the first bit sequence and / or the second bit sequence on the mapping unit of the first matrix; modulating the bit mapped on each mapping unit to obtain a modulation symbol; spreading each modulation symbol using the corresponding OCC factor; mapping the spread modulation symbol on each mapping unit in the first matrix to the RE corresponding to the mapping unit in the first time-frequency resource; transmitting the first UCI and the first UL-SCH multiplexed information through the first time-frequency resource; wherein the first bit sequence includes the bit sequence corresponding to the first UCI, and the second bit sequence includes the bit sequence corresponding to the first UL-SCH.

[0195] In embodiment 3, the number of rows included in the first matrix is ​​determined according to the number of subcarriers used to transmit the first UCI and the first UL-SCH in the first time-frequency resource, and the number of columns included in the first matrix is ​​determined according to the number of symbols used to transmit the first UCI and the first UL-SCH in the first time-frequency resource; or, the mapping unit of the first matrix corresponds to the RE used to transmit the first UCI and the first UL-SCH in the first time-frequency resource.

[0196] In embodiment 3, the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol.

[0197] For example, in Example 3, when the waveform of the uplink PUSCH transmission is a CP-OFDM waveform, the terminal device maps the bit sequence corresponding to the first UCI and the bit sequence corresponding to the first UL-SCH onto a mapping unit in a first matrix determined according to the resource size used to transmit the first UCI and the first UL-SCH in the first time-frequency resource, and then modulates the bits mapped on each mapping unit to obtain a modulation symbol, spreads each modulation symbol using the corresponding OCC factor, and maps the spread modulation symbol on each mapping unit in the first matrix to the RE corresponding to the mapping unit for transmission.

[0198] It is understood that the DFT operation of the terminal device is applied when the waveform of the uplink PUSCH transmission is a DFT-S-OFDM waveform. For example, Examples 1 and 2. When the waveform of the uplink PUSCH transmission is a CP-OFDM waveform, the terminal device does not need to perform the DFT operation. For example, Example 3.

[0199] In some embodiments, the symbol-based OCC spread spectrum transmission method includes: within the matrix corresponding to the symbols included in the OCC spread spectrum unit, in the mapping unit corresponding to the same frequency domain position, the same modulation symbol on the mapping unit corresponding to different time domain positions is spread using different OCC factors in the OCC.

[0200] In some embodiments, the time slot-based OCC spread spectrum transmission method includes: in the matrix corresponding to the time slot included in the OCC spread spectrum unit, in the mapping unit corresponding to the same frequency domain position, the same modulation symbol on the mapping unit corresponding to different time domain positions is spread using different OCC factors in the OCC.

[0201] In the above embodiment, the symbol or time slot based OCC spread spectrum transmission method includes: within the matrix corresponding to the symbol or time slot included in the OCC spread spectrum unit, in the mapping unit corresponding to the same frequency domain position (for example, the same subcarrier), the same modulation symbol on the mapping unit corresponding to different time domain positions (for example, different symbols) is spread using different OCC factors in the OCC.

[0202] In some embodiments, the OCC spread spectrum transmission method based on the mapping block includes: within the matrix corresponding to the mapping block included in the OCC spread spectrum unit, in the mapping unit corresponding to the same time domain position, the same modulation symbol on the mapping unit corresponding to different frequency domain positions is spread using different OCC factors in the OCC.

[0203] In the above embodiment, the OCC spread spectrum transmission method based on the mapping block includes: in the matrix corresponding to the mapping block included in the OCC spread spectrum unit, in the mapping unit corresponding to the same time domain position (for example, the same symbol), the same modulation symbol on the mapping unit corresponding to different frequency domain positions (for example, different subcarriers) is spread using different OCC factors in the OCC.

[0204] In some embodiments, the OCC spread spectrum transmission method based on symbols and mapping blocks includes: in the matrix corresponding to the symbols included in the OCC spread spectrum unit, in the mapping units corresponding to the same frequency domain positions, the same modulation symbols on the mapping units corresponding to different time domain positions are spread using different OCC factors in the OCC; in the matrix corresponding to the mapping blocks included in the OCC spread spectrum unit, in the mapping units corresponding to the same time domain positions, the same modulation symbols on the mapping units corresponding to different frequency domain positions are spread using different OCC factors in the OCC.

[0205] In some embodiments, an OCC spread spectrum transmission method based on time slots and mapping blocks includes: in a matrix corresponding to the time slots included in the OCC spread spectrum unit, in a mapping unit corresponding to the same frequency domain position, the same modulation symbols on mapping units corresponding to different time domain positions are spread using different OCC factors in the OCC; in a matrix corresponding to the mapping blocks included in the OCC spread spectrum unit, in a mapping unit corresponding to the same time domain position, the same modulation symbols on mapping units corresponding to different frequency domain positions are spread using different OCC factors in the OCC.

[0206] In the above embodiment, the OCC spread spectrum transmission method based on symbols and mapping blocks includes: in the matrix corresponding to the symbols or time slots included in the OCC spread spectrum unit, in the mapping units corresponding to the same frequency domain position (for example, the same subcarrier), the same modulation symbols on the mapping units corresponding to different time domain positions (for example, different symbols) are spread using different OCC factors in the OCC; in the matrix corresponding to the mapping block included in the OCC spread spectrum unit, in the mapping units corresponding to the same time domain position (for example, the same symbol), the same modulation symbols on the mapping units corresponding to different frequency domain positions (for example, different subcarriers) are spread using different OCC factors in the OCC.

[0207] In some embodiments, when the transmission mode of OCC spread spectrum corresponding to the above-mentioned first PUSCH includes an OCC spread spectrum transmission mode based on symbols or time slots, the above-mentioned OCC spread spectrum unit includes the minimum time domain unit for spreading using different OCC factors in the above-mentioned first OCC; and / or, when the transmission mode of OCC spread spectrum corresponding to the above-mentioned first PUSCH includes an OCC spread spectrum transmission mode based on mapping blocks, the above-mentioned OCC spread spectrum unit includes the minimum mapping block unit for spreading using different OCC factors in the above-mentioned first OCC.

[0208] In other words, when the transmission mode of OCC spreading corresponding to the first PUSCH includes a symbol- or slot-based OCC spreading transmission mode, the symbols or slots included in the OCC spreading unit include: a minimum set of symbols or a minimum set of slots that are spread using different OCC factors in the first OCC. When the transmission mode of OCC spreading corresponding to the first PUSCH includes a mapping block-based OCC spreading transmission mode, the mapping blocks included in the OCC spreading unit include: a minimum set of mapping blocks that are spread using different OCC factors in the first OCC.

[0209] In some embodiments, the number of time domain units included in the OCC spreading unit corresponds to one of the following: M PUSCHs, where M is an integer multiple of N and N is the OCC length; 1 PUSCH; M data symbols, where M is an integer multiple of N and N is the OCC length.

[0210] In some embodiments, the size of the mapping block included in the OCC spreading unit corresponds to one of the following: a physical resource block (PRB) occupied by the first PUSCH transmission; 1 PRB; 1 resource block group (RB Group, RBG).

[0211] In some embodiments, the first time-frequency resource includes an integer number of time domain units included in an OCC spreading unit; or, the time domain unit included in an OCC spreading unit includes multiple first time domain resources, wherein the time domain unit is a symbol or a time slot.

[0212] That is, the time domain units included in the first time-frequency resource include time domain units included in an integer number of OCC spreading units; or, the time domain units included in one OCC spreading unit include time domain units included in multiple first time domain resources.

[0213] For example, the first time-frequency resource includes an integer number of symbols or time slots included in an OCC spreading unit; or, the symbols or time slots included in one OCC spreading unit include multiple first time domain resources.

[0214] For example, when the first PUSCH corresponds to a symbol- or time slot-based OCC spread spectrum transmission mode and the number of symbols or time slots included in the OCC spreading unit is 1 PUSCH (e.g., data symbols included in 1 PUSCH) or M data symbols, the first time-frequency resource includes an integer number of symbols or time slots included in the OCC spreading unit. Accordingly, the first matrix includes matrices corresponding to the integer number of symbols or time slots included in the OCC spreading unit.

[0215] For another example, when the first PUSCH corresponds to a symbol- or time slot-based OCC spread spectrum transmission mode and the number of symbols or time slots included in the OCC spreading unit is multiple PUSCHs, the symbols or time slots included in one OCC spreading unit include M of the above-mentioned first time domain resources. Accordingly, the matrices corresponding to the symbols or time slots included in one OCC spreading unit include M first matrices.

[0216] In some embodiments, the first time-frequency resource includes mapping blocks including an integer number of OCC spreading units.

[0217] For example, when the first PUSCH corresponds to the mapping block-based OCC spreading transmission mode, the first time-frequency resource includes mapping blocks included in an integer number of OCC spreading units. Accordingly, the first matrix includes matrices corresponding to the mapping blocks included in the integer number of OCC spreading units.

[0218] In some embodiments, the first time-frequency resource includes time domain units comprised by an integer number of OCC spreading units, and the first time-frequency resource includes mapping blocks comprised by an integer number of OCC spreading units.

[0219] For example, the first time-frequency resource includes symbols or time slots included in an integer number of OCC spreading units, and the first time-frequency resource includes mapping blocks included in an integer number of OCC spreading units.

[0220] For example, when the first PUSCH corresponds to a symbol-and-mapping-block based OCC spread spectrum transmission mode, the first time-frequency resource includes symbols included in an integer number of OCC spreading units and includes mapping blocks included in an integer number of OCC spreading units. Accordingly, the first matrix includes matrices corresponding to the symbols included in the integer number of OCC spreading units and includes matrices corresponding to the mapping blocks included in the integer number of OCC spreading units.

[0221] In some embodiments, mapping the first bit sequence and / or the second bit sequence onto the mapping units of the first matrix includes one or more of the following situations: within a matrix corresponding to a symbol included in at least one OCC spreading unit in the first matrix, or within multiple first matrices corresponding to time slots included in an OCC spreading unit, in a mapping unit corresponding to the same frequency domain position, mapping the same first bit sequence and / or second bit sequence onto the mapping units corresponding to different time domain positions that use different OCC factors in the OCC for spreading; within a matrix corresponding to a mapping block included in at least one OCC spreading unit in the first matrix, in a mapping unit corresponding to the same time domain position, mapping the same first bit sequence and / or second bit sequence onto the mapping units corresponding to different frequency domain positions that use different OCC factors in the OCC for spreading.

[0222] The mapping of the first bit sequence and / or the second bit sequence onto the mapping units of the first matrix includes at least one of the following situations: within a matrix corresponding to a symbol included in at least one OCC spreading unit in the first matrix, or within multiple first matrices corresponding to time slots included in an OCC spreading unit, in a mapping unit corresponding to the same frequency domain position (for example, the same subcarrier), the same first bit sequence and / or second bit sequence is mapped onto mapping units corresponding to different time domain positions (for example, different symbols) that are spread using different OCC factors in the OCC; within a matrix corresponding to a mapping block included in at least one OCC spreading unit in the first matrix, in a mapping unit corresponding to the same time domain position (for example, the same symbol), the same first bit sequence and / or second bit sequence is mapped onto mapping units corresponding to different frequency domain positions (for example, different subcarriers) that are spread using different OCC factors in the OCC.

[0223] In some embodiments, mapping the first bit sequence and / or the second bit sequence on the mapping units of the first matrix includes one or more of the following situations: within the matrix corresponding to the symbol included in each OCC spreading unit in the first matrix, or, within multiple first matrices corresponding to the time slots included in an OCC spreading unit, in the mapping units corresponding to the same frequency domain position, mapping the same first bit sequence and / or second bit sequence on the mapping units corresponding to different time domain positions that use different OCC factors in the OCC for spreading; within the matrix corresponding to the mapping block included in each OCC spreading unit in the first matrix, in the mapping units corresponding to the same time domain position, mapping the same first bit sequence and / or second bit sequence on the mapping units corresponding to different frequency domain positions that use different OCC factors in the OCC for spreading.

[0224] The mapping of the first bit sequence and the second bit sequence onto the mapping units of the first matrix includes at least one of the following situations: within the matrix corresponding to the symbol included in each OCC spreading unit in the first matrix, or within multiple first matrices corresponding to the time slots included in an OCC spreading unit, in the mapping units corresponding to the same frequency domain position (for example, the same subcarrier), the same first bit sequence and / or second bit sequence is mapped onto the mapping units corresponding to different time domain positions (for example, different symbols) that are spread using different OCC factors in the OCC; within the matrix corresponding to the mapping block included in each OCC spreading unit in the first matrix, in the mapping units corresponding to the same time domain position (for example, the same symbol), the same first bit sequence and / or second bit sequence is mapped onto the mapping units corresponding to different frequency domain positions (for example, different subcarriers) that are spread using different OCC factors in the OCC.

[0225] In some embodiments, the bit sequence includes the first bit sequence, and mapping the bit sequence onto the mapping unit of the first matrix includes at least one of the following situations:

[0226] Mapping the first bit sequence onto the mapping units of the first matrix in a rate matching manner;

[0227] Mapping the first bit sequence onto the mapping units of the first matrix in a punctured manner;

[0228] The first subsequence in the first bit sequence is mapped onto the mapping unit of the first matrix in a rate matching manner, and the second subsequence in the first bit sequence is mapped onto the mapping unit of the first matrix in a puncturing manner.

[0229] In some embodiments, mapping the first bit sequence and / or the second bit sequence onto a mapping unit of the first matrix includes one or more of the following situations:

[0230] Mapping the first bit sequence onto the mapping units of the first matrix in a rate matching manner;

[0231] mapping the first bit sequence onto the mapping units of the first matrix in a punctured manner;

[0232] The first subsequence in the first bit sequence is mapped onto the mapping unit of the first matrix in a rate matching manner, and the second subsequence in the first bit sequence is mapped onto the mapping unit of the first matrix in a puncturing manner.

[0233] For example, when the first bit sequence includes only HARQ-ACK information and the number of bits of the HARQ-ACK information is less than or equal to 2, the first bit sequence is mapped onto the mapping units of the first matrix in a punctured manner.

[0234] For another example, when the first bit sequence does not include HARQ-ACK information (and optionally includes other UCI such as CSI Part 1 and / or CSI Part 2), or includes HARQ-ACK information and the number of HARQ-ACK information bits is greater than 2 (and optionally includes other UCI such as CSI Part 1 and / or CSI Part 2), the first bit sequence is mapped to the mapping unit of the first matrix in a rate matching manner.

[0235] For another example, when the first bit sequence includes HARQ-ACK information and other UCI information less than or equal to 2 bits, the other UCI information corresponds to the first subsequence, the HARQ-ACK information corresponds to the second subsequence, and the first subsequence in the first bit sequence is mapped to the mapping unit of the first matrix in a rate matching manner, and the second subsequence in the first bit sequence is mapped to the mapping unit of the first matrix in a perforated manner.

[0236] In some embodiments, when the first UCI includes only CSI Part 1, the first subsequence includes a bit sequence corresponding to the CSI Part 1, the second subsequence includes a bit sequence corresponding to the assumed 2-bit HARQ-ACK information, and the mapping of the bit sequence onto the mapping unit of the first matrix includes:

[0237] The first subsequence is mapped onto the mapping units of the first matrix in a rate matching manner, and the second subsequence is mapped onto the mapping units of the first matrix in a puncturing manner.

[0238] In some embodiments, when the first UCI includes only CSI Part 1, mapping the first bit sequence and / or the second bit sequence to a mapping element of the first matrix includes: mapping the first bit sequence to a mapping element of the first matrix. Optionally, when the number of HARQ-ACK bits is 2, mapping the bit sequence corresponding to the HARQ-ACK bit to a mapping element corresponding to an RE reserved for HARQ-ACK.

[0239] Among them, if the actual transmitted HARQ-ACK bits are less than 2 (for example, no HARQ-ACK bits or only 1 bit), it is necessary to assume that the HARQ-ACK bits are 2 bits, and the insufficient part needs to be padded with 0 to 2 bits, so as to fill the reserved REs and avoid the occurrence of blank REs with no energy in the PUSCH (avoiding the reserved REs from not being sent). When using OCC transmission, it is also necessary to fill the reserved REs and perform OCC scrambling operations.

[0240] In some embodiments, as described above, the number of time domain units included in the OCC spreading unit corresponds to one of the following: M PUSCHs, where M is an integer multiple of N, and N is the OCC length; 1 PUSCH; M data symbols, where M is an integer multiple of N, and N is the OCC length.

[0241] The data symbols here are data symbols that do not include DMRS symbols (i.e., symbols used to transmit the first UCI and / or the first UL-SCH). The data symbols occupied by a PUSCH transmission are symbols allocated for PUSCH transmission that are not used for DMRS transmission. For example, if the first PUSCH includes 10 symbols, where the DMRS symbols are symbols 0 and 4, then the data symbols occupied by the first PUSCH transmission are symbols 1, 2, 3, 5, 6, 7, 8, and 9.

[0242] In addition, the number of symbols or time slots included in the OCC spreading unit is M PUSCHs, which can be understood as the number of time slots included in the OCC spreading unit is M time slots, where each time slot includes one PUSCH; or, the number of time slots included in the OCC spreading unit is an integer multiple of M time slots, where the integer multiple of M time slots are used to transmit M PUSCHs. For example, in a scenario where a TB is mapped to multiple time slots, assuming that 1 TB is mapped to 2 time slots for transmission, the number of time slots included in the OCC spreading unit is 2*M time slots, where every 2 time slots are used to transmit one PUSCH, and the 2*M time slots are used to transmit M PUSCHs.

[0243] In addition, the number of symbols or time slots included in the OCC spreading unit is 1 PUSCH, which can be understood as the number of symbols included in the OCC spreading unit is the number of data symbols included in 1 PUSCH.

[0244] In some embodiments, when the number of time domain units included in the OCC spreading unit corresponds to M PUSCHs, the PUSCH is repeatedly transmitted K times, K is an integer multiple of M, and the interval between data symbols associated with two adjacent OCC factors is the number of data symbols included in M / N PUSCHs.

[0245] In some embodiments, when the number of time domain units included in the OCC spreading unit corresponds to one PUSCH, the interval between data symbols associated with two adjacent OCC factors is the ratio of the number of data symbols included in one PUSCH to the OCC length.

[0246] In some embodiments, when the number of time domain units included in the OCC spreading unit corresponds to M data symbols, the interval between two adjacent data symbols associated with the OCC factors is determined by one or more of the following methods:

[0247] The value configured by the network device, the protocol preset value, and the ratio of the number of data symbols included in a PUSCH to the OCC length.

[0248] The following example illustrates how the terminal device maps the first bit sequence corresponding to the first UCI and the second bit sequence corresponding to the first UL-SCH on the mapping unit of the first matrix in scenarios corresponding to the number of symbols or time slots included in the above-mentioned different time-domain OCC spreading unit sizes. The number of rows included in the first matrix is ​​determined according to the number of subcarriers used to transmit the first UCI and the first UL-SCH in the first time-frequency resource, and the number of columns included in the first matrix is ​​determined according to the number of symbols used to transmit the first UCI and the first UL-SCH in the first time-frequency resource. The rows are arranged from small to large according to the subcarrier index, and the columns are arranged from small to large according to the symbol index and / or time slot index, and each mapping unit in the first matrix corresponds to an RE in the first time-frequency resource for transmitting the first UCI and the first UL-SCH.

[0249] Case 1-1: Time Domain OCC Spreading Unit Size: The number of symbols or time slots included in the OCC spreading unit is M PUSCHs, where M is an integer multiple of N and N is the OCC length. In this case, the PUSCH is repeated K times, where K is an integer multiple of M. The interval between two adjacent OCC factor-associated data symbols is M / N PUSCH data symbols.

[0250] FIG9 is a schematic diagram of mapping when the number of symbols or time slots included in the OCC spreading unit is M PUSCH (M=2); as shown in FIG9 , it shows a schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the size of the time domain OCC spreading unit is M PUSCH. In this example, it is assumed that the first time-frequency resource includes 12 data symbols, the first OCC is {w(0), w(1)} (i.e., the OCC factors are w(0) and w(1) respectively), the first OCC length is N=2, the number of symbols or time slots included in one OCC spreading unit is M=2 data symbols included in the PUSCH, and the interval between two adjacent data symbols associated with the OCC factors is the number of data symbols included in one PUSCH. The first PUSCH is repeatedly transmitted twice in the time domain, i.e., it occupies the size of two first time-frequency resources, wherein the first UCI and the first UL-SCH are repeatedly transmitted twice in the time domain. Among the data symbols included in one PUSCH, the first UCI occupies most of the resources in the first and second data symbols, represented by UCI1 and UCI2 in Figure 9. The first UL-SCH occupies the other resources of the 12 data symbols except the resources occupied by the first UCI, represented by Data 1 to Data 11 in Figure 9.

[0251] As shown in Figure 9, the terminal device maps the first bit sequence and the second bit sequence on the mapping unit of the first matrix, wherein the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol. The bits mapped on each mapping unit are then modulated to obtain a modulation symbol. The modulation symbols on the mapping unit of the first matrix are repeated twice, wherein w(0) is used to spread the modulation symbols on the mapping unit of the first first matrix, and w(1) is used to spread the modulation symbols on the mapping unit of the second first matrix. Then, the terminal device performs a DFT operation on the modulation symbols after spreading on each column of the mapping unit in each first matrix, and maps the information obtained to the symbol corresponding to the column in the first time-frequency resource corresponding to the first matrix. Alternatively, the DFT operation can be performed first and then the spreading is performed, which is not limited to this.

[0252] Figure 10 is another mapping diagram when the number of symbols or time slots included in the OCC spreading unit is M PUSCH (M=2), which provides another schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the number of symbols or time slots included in the OCC spreading unit is M PUSCH. In this example, it is assumed that the first time-frequency resource includes 12 data symbols, the first OCC is {w(0), w(1)}, the first OCC length N=2, the number of symbols or time slots included in one OCC spreading unit is M=2 data symbols included in the PUSCH, and the interval between two adjacent data symbols associated with the OCC factor is the number of data symbols included in one PUSCH. The first PUSCH is repeatedly transmitted 4 times in the time domain, that is, it occupies the size of 4 first time-frequency resources, wherein the first UL-SCH is repeatedly transmitted 4 times in the time domain, and the first UCI is repeatedly transmitted 2 times in the time domain (that is, the first UCI is only transmitted within the symbols or time slots included in one OCC spreading unit). In the symbols or time slots included in the OCC spreading unit that carries the first UCI, among the data symbols included in one PUSCH, the first UCI occupies most of the resources in the first and second data symbols, represented by UCI1 and UCI2 in Figure 10. The first UL-SCH occupies the remaining resources of the 12 data symbols except for the resources occupied by the first UCI, represented by Data 1 to Data 11 in Figure 10. In the symbols or time slots included in the OCC spreading unit that does not carry the first UCI, the first UL-SCH occupies the 12 data symbols included in one PUSCH, represented by Data 1' to Data 12' in Figure 10.

[0253] As shown in Figure 10, within the symbol or time slot included in the OCC spreading unit carrying the first UCI, the terminal device maps the first bit sequence (corresponding to UCI1 and UCI2) and the second bit sequence (corresponding to data 1 to data 11) on the mapping unit of the first matrix, wherein the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol. The bits mapped on each mapping unit are then modulated to obtain the modulation symbol. The modulation symbols on the mapping unit of the first matrix are repeated twice, wherein the modulation symbols on the mapping unit of the first first matrix are spread using w(0), and the modulation symbols on the mapping unit of the second first matrix are spread using w(1). Then, the terminal device performs a DFT operation on the modulation symbols spread on each column of the mapping unit in each first matrix, and maps the information obtained to the symbol corresponding to the column in the first time-frequency resource corresponding to the first matrix. Alternatively, the DFT operation can be performed first and then the spreading is performed, which is not limited to this.

[0254] In the symbols or time slots included in the OCC spreading unit that does not carry the first UCI, the terminal device maps the second bit sequence (corresponding to data 1' to data 12') on the mapping unit of the first matrix, wherein the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol. The bits mapped on each mapping unit are then modulated to obtain the modulation symbol. The modulation symbols on the mapping unit of the first matrix are repeated twice, wherein w(0) is used to spread the modulation symbols on the mapping unit of the first first matrix, and w(1) is used to spread the modulation symbols on the mapping unit of the second first matrix. Then, the terminal device performs a DFT operation on the modulation symbols after spreading on each column of the mapping unit in each first matrix, and maps the information obtained to the symbol corresponding to the column in the first time-frequency resource corresponding to the first matrix. Alternatively, the DFT operation can be performed first and then the spreading is performed, which is not limited to this.

[0255] Case 1-2: The number of symbols or time slots included in the OCC spreading unit is one PUSCH. In this case, the interval between data symbols associated with two adjacent OCC factors is the ratio of the number of data symbols included in one PUSCH to the OCC length.

[0256] FIG11 is a schematic diagram of mapping when the number of symbols or time slots included in the OCC spreading unit is 1 PUSCH, which shows a schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the number of symbols or time slots included in the OCC spreading unit is 1 PUSCH. In this example, it is assumed that the first time-frequency resource includes 12 data symbols, the first OCC is {w(0), w(1), w(2), w(3)}, the first OCC length N=4, the interval between the data symbols associated with two adjacent OCC factors is 3 (i.e., 12 / 4) data symbols, and the first PUSCH includes the symbols or time slots included in 1 OCC spreading unit. Among them, the first UCI occupies most of the resources in the first data symbol and the second data symbol, which are represented by UCI1 and UCI2 in FIG11, and the first UL-SCH occupies other resources of the 12 data symbols except the resources occupied by the first UCI, which are represented by data 1 and data 2 in FIG11.

[0257] As shown in Figure 11, the terminal device maps the first bit sequence and the second bit sequence onto mapping elements of the first matrix, where the number of bits mapped onto each mapping element is determined based on the modulation order of the modulation symbol. The bits mapped onto each mapping element are then modulated to obtain a modulation symbol, and each modulation symbol is spread using a corresponding OCC factor. Specifically, w(0) is used to spread the modulation symbol of UCI1 corresponding to the first data symbol, the modulation symbol of UCI2 corresponding to the second data symbol, the modulation symbol of data 1 corresponding to the second data symbol, and the modulation symbol of data 2 corresponding to the third data symbol; w(1) is used to spread the modulation symbol of UCI1 corresponding to the fourth data symbol, the modulation symbol of UCI2 corresponding to the fifth data symbol, the modulation symbol of data 1 corresponding to the fifth data symbol, and the modulation symbol of data 2 corresponding to the sixth data symbol; w(2) is used to spread the modulation symbol of UCI1 corresponding to the seventh data symbol, the modulation symbol of UCI2 corresponding to the eighth data symbol, the modulation symbol of data 1 corresponding to the eighth data symbol, and the modulation symbol of data 2 corresponding to the ninth data symbol; w(3) is used to spread the modulation symbol of UCI1 corresponding to the tenth data symbol, the modulation symbol of UCI2 corresponding to the eleventh data symbol, the modulation symbol of data 1 corresponding to the eleventh data symbol, and the modulation symbol of data 2 corresponding to the twelfth data symbol. Then, the terminal device maps the information obtained by performing a DFT operation on the modulated symbols spread on each column mapping unit in the first matrix to the symbols corresponding to the column in the first time-frequency resource. Alternatively, the DFT operation can be performed first and then the spreading operation, which is not limited to this.

[0258] Case 1-3: The number of symbols or time slots included in the OCC spreading unit is M data symbols, where M is an integer multiple of N, and N is the OCC length. In this case, the interval between data symbols associated with two adjacent OCC factors is one of the following: a value configured by the network equipment, a default value set by the protocol, or the ratio of the number of data symbols included in a PUSCH to the OCC length.

[0259] Figure 12 is a mapping diagram of the number of symbols or time slots included in the OCC spreading unit being M=4 data symbols, which shows a schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the number of symbols or time slots included in the OCC spreading unit is M data symbols. In this example, it is assumed that the first time-frequency resource includes 12 data symbols, the first OCC is {w(0), w(1)}, the first OCC length N=2, the number of symbols or time slots included in the OCC spreading unit is M=4, the interval between two adjacent data symbols associated with the OCC factor is 2 data symbols, and the first PUSCH includes symbols or time slots included in 3 OCC spreading units. Among them, the first UCI occupies most of the resources in the first data symbol and the second data symbol, represented by UCI1 and UCI2 in Figure 12, and the first UL-SCH occupies other resources of the 12 data symbols except the resources occupied by the first UCI, represented by data 1 to data 5 in Figure 12.

[0260] As shown in Figure 12, the terminal device maps the first bit sequence and the second bit sequence onto mapping elements of the first matrix, where the number of bits mapped onto each mapping element is determined based on the modulation order of the modulation symbol. The bits mapped onto each mapping element are then modulated to obtain a modulation symbol, and each modulation symbol is spread using a corresponding OCC factor. Specifically, w(0) is used to spread the modulation symbol of UCI1 corresponding to the first data symbol, the modulation symbol of UCI2 corresponding to the second data symbol, and the modulation symbol of data 1 corresponding to the second data symbol; w(1) is used to spread the modulation symbol of UCI1 corresponding to the third data symbol, the modulation symbol of UCI2 corresponding to the fourth data symbol, and the modulation symbol of data 1 corresponding to the fourth data symbol; w(0) is used to spread the modulation symbol of data 2 corresponding to the fifth data symbol and the modulation symbol of data 3 corresponding to the sixth data symbol; w(1) is used to spread the modulation symbol of data 2 corresponding to the seventh data symbol and the modulation symbol of data 3 corresponding to the eighth data symbol; w(0) is used to spread the modulation symbol of data 4 corresponding to the ninth data symbol and the modulation symbol of data 5 corresponding to the tenth data symbol; and w(1) is used to spread the modulation symbol of data 4 corresponding to the eleventh data symbol and the modulation symbol of data 5 corresponding to the twelfth data symbol. Then, the terminal device maps the information obtained by performing a DFT operation on the modulated symbols spread on each column mapping unit in the first matrix to the symbols corresponding to the column in the first time-frequency resource. Alternatively, the DFT operation can be performed first and then the spreading operation, which is not limited to this.

[0261] In some embodiments, as described above, the size of the mapping block included in the OCC spreading unit corresponds to one of the following: a physical resource block PRB occupied by the first PUSCH transmission; 1 PRB; 1 resource block group RBG.

[0262] In some embodiments, when the size of the mapping block included in the OCC spreading unit corresponds to the number P of PRBs occupied by the first PUSCH transmission, the interval between the number of subcarriers associated with two adjacent OCC factors is determined by one or more of the following methods: a value configured by the network device, a protocol preset value, or the ratio of the number of subcarriers included in P PRBs to the OCC length.

[0263] In some embodiments, when the size of the mapping block included in the OCC spread spectrum unit corresponds to 1 PRB, the interval between the number of subcarriers associated with two adjacent OCC factors is determined by one or more of the following methods: a value configured by the network device, a protocol preset value, and the ratio of the number of subcarriers included in 1 PRB to the OCC length.

[0264] In some embodiments, when the size of the mapping block included in the OCC spreading unit corresponds to 1 RBG, the interval between the number of subcarriers associated with two adjacent OCC factors is determined by one or more of the following methods: a value configured by the network device, a protocol preset value, and the ratio of the number of subcarriers included in 1 RBG to the OCC length.

[0265] The following example illustrates how the terminal device maps the first bit sequence corresponding to the first UCI and the second bit sequence corresponding to the first UL-SCH onto the mapping unit of the first matrix in the scenario corresponding to the size of the mapping block included in the above-mentioned different OCC spread spectrum units, wherein the number of rows included in the first matrix is ​​determined according to the number of subcarriers used to transmit the first UCI and the first UL-SCH in the first time-frequency resource, and the number of columns included in the first matrix is ​​determined according to the number of symbols used to transmit the first UCI and the first UL-SCH in the first time-frequency resource. The rows are arranged from small to large according to the subcarrier index, and the columns are arranged from small to large according to the symbol index, and each mapping unit in the first matrix corresponds to an RE in the first time-frequency resource for transmitting the first UCI and the first UL-SCH.

[0266] Case 2-1: The size of the mapping block included in the OCC spreading unit is the number P of PRBs occupied by the first PUSCH transmission, where P is an integer multiple of N or P*12 is an integer multiple of N, where N is the OCC length. In this case, the interval between the number of subcarriers associated with two adjacent OCC factors is one of the following: a value configured by the network device, a value preset by the protocol, or the ratio of the number of subcarriers included in P PRBs to the OCC length.

[0267] Figure 13 is a mapping diagram of the size of the mapping block included in the OCC spreading unit being the number P of PRBs occupied by the first PUSCH transmission, which shows a schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the size of the mapping block included in the OCC spreading unit is the number P of PRBs occupied by the first PUSCH transmission. In this example, assuming that the first time-frequency resource includes P PRBs, the first OCC is {w(0), w(1)}, and the first OCC length N=2, the size of the mapping block included in the OCC spreading unit is P PRBs. The interval between the number of subcarriers associated with two adjacent OCC factors is P*12 / N subcarriers. For example, if P is 10, the interval between the number of subcarriers associated with two adjacent OCC factors is 60 subcarriers. For another example, if P is 5, the interval between the number of subcarriers associated with two adjacent OCC factors is 30 subcarriers. Assume that among the 12 data symbols included in the first PUSCH, the first UCI occupies most of the resources in the first data symbol and the second data symbol, represented by UCI1 and UCI2 in Figure 13, and the first UL-SCH occupies other resources in the 12 data symbols except the resources occupied by the first UCI, represented by data 1 to data 11 in Figure 13.

[0268] As shown in Figure 13, the terminal device maps the first bit sequence and the second bit sequence on the mapping unit of the first matrix, wherein the number of bits mapped on each mapping unit is determined according to the modulation order of the modulation symbol. The bits mapped on each mapping unit are then modulated to obtain a modulation symbol, and each modulation symbol is spread using the corresponding OCC factor. Specifically, w(0) is used to spread the modulation symbols of UCI1, UCI2, and data 1 to data 11 corresponding to the first P*6 subcarriers in the P PRBs; w(1) is used to spread the modulation symbols of UCI1, UCI2, and data 1 to data 11 corresponding to the last P*6 subcarriers in the P PRBs. Then, the terminal device performs a DFT operation on the modulation symbols after spreading on each column of the mapping unit in the first matrix, and maps the information obtained to the symbol corresponding to the column in the first time-frequency resource.

[0269] Case 2-2: The size of the mapping block included in the OCC spreading unit is 1 PRB, where N is divisible by 12 (i.e., 12 is an integer multiple of N), and N is the OCC length. In this case, the interval between the number of subcarriers associated with two adjacent OCC factors is one of the following: a value configured by the network device, a default value set by the protocol, or the ratio of the number of subcarriers included in 1 PRB (i.e., 12) to the OCC length.

[0270] Figure 14 is a mapping diagram of a mapping block of 1 PRB in the OCC spreading unit, which shows a schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the mapping block of the OCC spreading unit is 1 PRB. In this example, it is assumed that the first time-frequency resource includes 2 PRBs, the first OCC is {w(0), w(1)}, and the length of the first OCC is N=2. The interval between the number of subcarriers associated with two adjacent OCC factors is 6 subcarriers. Assume that among the 12 data symbols included in the first PUSCH, the first UCI occupies most of the resources in the first data symbol and the second data symbol, which are represented by UCI1 to UCI4 in Figure 14, and the first UL-SCH occupies other resources in the 12 data symbols except the resources occupied by the first UCI, which are represented by data 1 to data 21 in Figure 14.

[0271] As shown in Figure 14, the terminal device maps the first bit sequence and the second bit sequence onto mapping elements of the first matrix, where the number of bits mapped onto each mapping element is determined based on the modulation order of the modulation symbol. The bits mapped onto each mapping element are then modulated to obtain a modulation symbol, and each modulation symbol is spread using a corresponding OCC factor. Specifically, w(0) is used to spread the modulation symbols of UCI1, UCI3, data 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 corresponding to the first 6 subcarriers in the 1st PRB; w(1) is used to spread the modulation symbols of UCI1, UCI3, data 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 corresponding to the last 6 subcarriers in the 1st PRB; w(0) is used to spread the modulation symbols of UCI2, UCI4, data 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 corresponding to the first 6 subcarriers in the 2nd PRB; w(1) is used to spread the modulation symbols of UCI2, UCI4, data 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 corresponding to the last 6 subcarriers in the 2nd PRB. Then, the terminal device maps the information obtained after performing a DFT operation on the modulated symbols spread on each column mapping unit in the first matrix to the symbols corresponding to the column in the first time-frequency resource.

[0272] Case 2-3: The size of the mapping block included in the OCC spreading unit is 1 RBG, where N is divisible by the number of subcarriers included in 1 RBG (i.e., the number of subcarriers included in 1 RBG is an integer multiple of N), and N is the OCC length. In this case, the interval between the number of subcarriers associated with two adjacent OCC factors is one of the following: a value configured by the network device, a default value set by the protocol, or the ratio of the number of subcarriers included in 1 RBG to the OCC length.

[0273] Figure 15 is a mapping diagram of a mapping block of 1 RBG included in the OCC spreading unit, which shows a schematic diagram of mapping the first UCI and the first UL-SCH on the first matrix when the mapping block of the OCC spreading unit is 1 RBG. In this example, it is assumed that the first time-frequency resource includes 2 RBGs, the first OCC is {w(0), w(1)}, and the length of the first OCC is N=2. The interval between the number of subcarriers associated with two adjacent OCC factors is the ratio of the number of subcarriers included in 1 RBG to the OCC length. It is assumed that among the 12 data symbols included in the first PUSCH, the first UCI occupies most of the resources in the first data symbol and the second data symbol, which are represented by UCI1 to UCI4 in Figure 15, and the first UL-SCH occupies other resources in the 12 data symbols except the resources occupied by the first UCI, which are represented by data 1 to data 21 in Figure 15.

[0274] As shown in Figure 15, the terminal device maps the first bit sequence and the second bit sequence onto mapping elements of the first matrix, where the number of bits mapped onto each mapping element is determined based on the modulation order of the modulation symbol. The bits mapped onto each mapping element are then modulated to obtain a modulation symbol, and each modulation symbol is spread using a corresponding OCC factor. Specifically, w(0) is used to spread the modulation symbols of UCI1, UCI3, data 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 corresponding to the first half of the subcarriers in the first RBG; w(1) is used to spread the modulation symbols of UCI1, UCI3, data 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20 corresponding to the second half of the subcarriers in the first RBG; w(0) is used to spread the modulation symbols of UCI2, UCI4, data 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 corresponding to the first half of the subcarriers in the second RBG; w(1) is used to spread the modulation symbols of UCI2, UCI4, data 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 corresponding to the second half of the subcarriers in the second RBG. Then, the terminal device maps the information obtained after performing a DFT operation on the modulated symbols spread on each column mapping unit in the first matrix to the symbols corresponding to the column in the first time-frequency resource.

[0275] Step 820: When the first time-frequency resource and the second time-frequency resource overlap in the time domain and the first physical uplink shared channel PUSCH is transmitted using an orthogonal cover code (OCC) spread spectrum transmission method, the network device receives uplink transmission information from the terminal device.

[0283] In NTN network scenarios, repeated transmission is often used to transmit PUSCH in order to improve the uplink coverage of a cell. To improve the uplink capacity of the system while meeting uplink coverage requirements, OCC spread spectrum transmission may be used for PUSCH. The solution shown in the above embodiment of the present application can be applied in NTN network scenarios to enhance the multiplexing method of UCI and PUSCH, so that different terminal devices can ensure orthogonality when using OCC to transmit PUSCH, thereby ensuring PUSCH transmission performance.
