[0002] In the existing NR (New Radio) system, the DMRS (Demodulation Reference Signal) of PUSCH (Physical Uplink Shared Channel) and PUCCH (Physical Uplink Control Channel) support multiplexing of multiple antenna ports / multiple users through orthogonal sequences.

[0003] In December 2023, the 3GPP (the 3rd Generation Partnership Project) RAN (Radio Access Network) #102 meeting decided to study the multiplexing of multiple users supported by orthogonal sequences on PUSCH in the "Non-Terrestrial Network (NTN) for NR (New Radio)" research project (Work Item, WI). That is, multiple users need to transmit code-domain orthogonal PUSCH within the same time-frequency resources. This multiplexing technology can significantly improve the uplink capacity and throughput. Summary of the Invention

It should be noted that this application can be applied to various wireless communication scenarios, such as communication scenarios of non-terrestrial networks (NTN) and terrestrial networks (TN), and achieve similar technical effects. In addition, adopting a unified solution for different scenarios (including but not limited to communication scenarios of non-terrestrial networks and terrestrial networks) helps to reduce hardware complexity and cost, or improve performance. Without conflict, the embodiments and features in any node of this application can be applied to any other node.

[0114] As an example, the orthogonal sequence of the PUSCH is configurable.

[0115] As an example, the orthogonal sequence of the PUSCH is configured by physical layer signaling.

[0116] As an example, the advantages of the above method include: small delay for the configuration to take effect.

[0118] As an example, the orthogonal sequence of PUSCH is configured by a MAC CE (Medium Access Control layer Control Element).

[0119] As an example, the orthogonal sequence of PUSCH is configured by RRC (Radio Resource Control) signaling.

[0120] As an example, the benefits of the above method include high reliability of configuration transmission.

[0121] As an example, the orthogonal sequence of PUSCH is an orthogonal sequence defined for PUSCH transmission.

[0122] As an example, the orthogonal sequence of PUSCH is an orthogonal sequence configured for application to PUSCH transmission.

[0123] As an example, the orthogonal sequence of PUSCH is an orthogonal sequence configured for application to the first signal.

[0124] As an example, the orthogonal sequence of PUSCH in this application includes an orthogonal cover code.

[0125] As an example, if the orthogonal sequence of PUSCH is applied to the first signal, then the length of the orthogonal sequence of PUSCH is at least 2.

[0126] As an example, if the orthogonal sequence of PUSCH is not applied to the first signal, it is equivalent to applying an orthogonal sequence of PUSCH with a length of 1 to the first signal.

[0127] As an example, the first signal includes a plurality of sub-signals, and each sub-signal in the plurality of sub-signals is a PUSCH repetition.

[0128] As an example, the first signal only includes the plurality of sub-signals.

[0129] As an example, the number of sub-signals in the plurality of signals is K, and the plurality of sub-signals are respectively in K different time slots.

[0130] As an example, the K is configurable.

[0131] As an example, the K is indicated by a higher layer parameter.

[0132] As an example, the K is indicated by the higher layer parameter numberOfRepetitions.

[0133] As an example, the K is indicated by the higher layer parameter numberOfRepetitionsExt.

[0134] As an example, the K is indicated by the higher layer parameter pusch-AggregationFactor.

[0135] As an example, the K is indicated by the higher layer parameter repK.

[0136] As an example, the K is indicated by the higher layer parameter repK-v1710.

[0137] As an example, the number of sub-signals in the plurality of signals is a positive integer multiple of the length of the orthogonal sequence of the PUSCH.

[0138] As an example, the terminal does not expect that the number of sub-signals in the plurality of signals is not a positive integer multiple of the length of the orthogonal sequence of the PUSCH.

[0139] As an example, when the number of sub-signals in the plurality of signals cannot be divided evenly by the length of the orthogonal sequence of the PUSCH, the orthogonal sequence of the PUSCH is not applied to the first signal.

[0140] As an example, the first signal includes multiple PUSCH repetitions, the multiple PUSCH repetitions are in different time slots respectively, and the number of the multiple PUSCH repetitions is the K.

[0141] As an example, the SRS resource set corresponding to the first signal refers to: the SRS resource set corresponding to the multiple PUSCH repetitions.

[0142] As an example, the SRS resource set corresponding to the first signal includes: the SRS resource set corresponding to each PUSCH repetition in the multiple PUSCH repetitions.

[0143] As an example, one PUSCH repetition in the multiple PUSCH repetitions corresponds to an SRS resource set, and this SRS resource set is associated with the time slot where this PUSCH repetition is located.

[0144] As an example, when an SRS resource set is applied to a time slot in which one of the multiple PUSCH repetitions is located, this PUSCH repetition corresponds to this SRS resource set.

[0145] As an example, the SRS resource set corresponding to the first signal is at least one SRS resource set in the first type of SRS resource sets.

[0146] As an example, the number of SRS resource sets corresponding to the first signal refers to the number of SRS resource sets in the first type of SRS resource sets.

[0147] As an example, each SRS resource set includes at least one SRS resource.

[0148] As an example, the first type of SRS resource sets is configurable.

[0149] As an example, the first type of SRS resource sets is configured by a higher layer parameter.

[0150] As an example, the first type of SRS resource sets is configured by the higher layer parameter srs-ResourceSetToAddModList.

[0151] As an example, the first type of SRS resource sets is configured by the higher layer parameter srs-ResourceSetToAddModListDCI-0-2.

[0152] As an example, the first type of SRS resource sets is an SRS resource set in which the corresponding higher layer parameter usage of the configuration by the higher layer parameter srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 is set to "nonCodebook" or set to "codebook".

[0153] As an example, the first type of SRS resource sets are two SRS resource sets in which the corresponding higher layer parameter usages of the configuration by the higher layer parameter srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 are both set to "nonCodebook" or both set to "codebook".

[0154] As an example, a higher layer parameter usage indicates that the first type of SRS resource set is used for codebook-based or non-codebook-based transmission.

[0155] As an example, when the number of SRS resource sets in the first type of SRS resource set is 1, the first type of SRS resource set includes only one SRS resource set, and the SRS resource set corresponding to the first signal is this SRS resource set.

[0156] As an example, when the number of SRS resource sets in the first type of SRS resource set is 2, the first type of SRS resource set includes a first SRS resource set and a second SRS resource set, and the SRS resource set corresponding to the first signal is at least one of the first SRS resource set and the second SRS resource set.

[0157] As an example, the first SRS resource set and the second SRS resource set are configured by the same higher layer parameter.

[0158] As an example, the first SRS resource set and the second SRS resource set each include at least one SRS resource.

[0159] As an example, the first SRS resource set is identified by an SRS-ResourceSetId, and the second SRS resource set is identified by an SRS-ResourceSetId.

[0160] As an example, the SRS-ResourceSetId of the first SRS resource set is different from the SRS-ResourceSetId of the second SRS resource set.

[0161] As an example, the SRS-ResourceSetId of the first SRS resource set is less than the SRS-ResourceSetId of the second SRS resource set.

[0162] As an example, the number of the SRS resource sets corresponding to the first signal is 1, or the first signaling indicates the number of the SRS resource sets corresponding to the first signal.

[0163] As an example, when the number of the SRS resource sets in the first type of SRS resource sets is 1, the number of the SRS resource sets corresponding to the first signal is 1; when the number of the SRS resource sets in the first type of SRS resource sets is 2, the number of the SRS resource sets corresponding to the first signal depends on the indication of the first signaling.

[0164] As an example, when the number of the SRS resource sets in the first type of SRS resource sets is 1, the first signaling does not include an SRS resource set indicator field; when the number of the SRS resource sets in the first type of SRS resource sets is 2, the first signaling includes an SRS resource set indicator field.

[0165] As an example, the first code point of the SRS resource set indicator field indicates that the SRS resource set corresponding to the first signal is the first SRS resource set or the second SRS resource set, and the number of the SRS resource sets corresponding to the first signal is 1.

[0166] As an example, the second code point of the SRS resource set indicator field indicates that the SRS resource set corresponding to the first signal is the first SRS resource set and the second SRS resource set, and the number of the SRS resource sets corresponding to the first signal is 2.

[0167] As an example, the bitwidth of the SRS resource set indicator field is 2 bits.

[0168] As an example, the first code point is "00".

[0169] As an example, the first code point is "01".

[0170] As an example, the second code point is "10".

[0171] As an example, the second code point is "11".

[0172] As an example, whether the orthogonal sequence of the PUSCH is applied to the first signal is related to the number of the SRS resource sets corresponding to the first signal, including: whether the orthogonal sequence of the PUSCH is applied to the first signal is related to whether the first signal can correspond to two SRS resource sets.

[0173] As an example, whether the first signal corresponds to two SRS resource sets depends on whether the orthogonal sequence of the PUSCH is applied to the first signal.

[0174] As a sub - embodiment of the above - mentioned embodiment, whether the first signal corresponds to two SRS resource sets means: whether the first signal can correspond to two SRS resource sets.

[0175] As a sub - embodiment of the above - mentioned embodiment, whether the first signal corresponds to two SRS resource sets means: whether the first signal is expected to correspond to two SRS resource sets.

[0178] As an embodiment, the first signal does not correspond to two SRS resource sets means: it is not expected that the first signal corresponds to two SRS resource sets.

[0179] As an embodiment, the first signal does not correspond to two SRS resource sets means: the terminal shall expect that the number of the SRS resource sets corresponding to the first signal is 1.

[0180] As an embodiment, when the orthogonal sequence of PUSCH is applied to the first signal:

[0181] When the number of SRS resource sets in the first - type SRS resource set is 1, the number of the SRS resource sets corresponding to the first signal is 1; when the number of SRS resource sets in the first - type SRS resource set is 2, the first signaling can indicate the first code point of the SRS resource indicator field, and the first signaling cannot indicate the second code point of the SRS resource indicator field.

[0182] As an embodiment, when the orthogonal sequence of PUSCH is applied to the first signal:

[0255] Example 3

[0256] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram for explaining an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture for controlling plane 300 is shown in three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to as PHY301 in this text. Layer 2 (L2 layer) 305 is on top of PHY301 and is responsible for the link between the first communication node device and the second communication node device, as well as between two UEs through PHY301. L2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for disordered reception due to HARQ (Hybrid Automatic Repeat Request). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). In the user plane 350, the radio protocol architecture is generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355. However, the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for the mapping between QoS (Quality of Service) flows and data radio bearers (DRBs) to support service diversity.

[0265] Example 4

[0266] Example 4 shows a schematic diagram of a first communication device and a second communication device according to this application, as shown in the appendix Figure 4 as shown. Figure 4 It is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0267] The first communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0268] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0269] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, the upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 layer. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream and then provides it to different antennas 420.

[0270] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the Fast Fourier Transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0271] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide an upper layer data packet to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the first communication device 410 described in the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into a multi-carrier / single-carrier symbol stream, and after an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides it to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0272] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receive function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement L1 layer functions. A controller / processor 475 implements L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the second communication device 450. The upper layer data packet from the controller / processor 475 may be provided to the core network.

[0468] As an embodiment, the first receiver A01 receives a first signal; the first transmitter A02 sends a first signal, and the transmission of the first signal depends on the first signal;

[0469] Whether the orthogonal sequence of PUSCH is applied to the first signal is related to the number of SRS resource sets corresponding to the first signal.

[0470] As an example, when the orthogonal sequence of PUSCH is applied to the first signal, the first signal does not correspond to two SRS resource sets; when the orthogonal sequence of PUSCH is not applied to the first signal, the first signal corresponds to two SRS resource sets.

[0471] As an example, when the number of the SRS resource sets corresponding to the first signal is 1, the orthogonal sequence of PUSCH is applied to the first signal; when the number of the SRS resource sets corresponding to the first signal is 2, whether the orthogonal sequence of PUSCH is applied to the first signal depends on the length of the orthogonal sequence of PUSCH.

[0472] As an example, the first orthogonal sequence is the orthogonal sequence of PUSCH; when the number of the SRS resource sets corresponding to the first signal is 1, the first orthogonal sequence is applied to the first signal; when the number of the SRS resource sets corresponding to the first signal is 2, the first orthogonal sequence is not applied to the first signal.

[0474] As an example, when the number of the SRS resource sets corresponding to the first signal is 2:

[0475] The multiple sub-signals are divided into at least two sub-signal groups; for each sub-signal group among the at least two sub-signal groups, the same SRS resource set is applied to all sub-signals in this sub-signal group, and the second orthogonal sequence is applied to this sub-signal group.

[0476] As an example, the second orthogonal sequence is the orthogonal sequence of PUSCH, and the length of the second orthogonal sequence is less than the length of the first orthogonal sequence.

[0478] If the first mapping mode is enabled, then the third orthogonal sequence is not applied to the first signal; if the second mapping mode is enabled, then the third orthogonal sequence is applied to the first signal.

[0479] As an example, the third orthogonal sequence is the orthogonal sequence of PUSCH, and the length of the third orthogonal sequence is not less than 4; the first mapping mode is a cyclic mapping mode or a sequential mapping mode, and the second mapping mode is a mapping mode other than the first mapping mode.

[0480] As an example, the first receiver A01 receives a first signaling; the first transmitter A02 transmits a first signal, and the transmission of the first signal depends on the first signaling.

[0481] Among them, whether the first signal can correspond to two SRS resource sets depends on whether the orthogonal sequence of PUSCH is applied to the first signal; when the orthogonal sequence of PUSCH is applied to the first signal, the first signal cannot correspond to two SRS resource sets; when the orthogonal sequence of PUSCH is not applied to the first signal, the first signal can correspond to two SRS resource sets.

[0482] As a sub - example of the above example, the two SRS resource sets are two SRS resource sets in which the corresponding higher - layer parameters usage set in the higher - layer parameter srs - ResourceSetToAddModList or srs - ResourceSetToAddModListDCI - 0 - 2 are both set to "nonCodebook" or both set to "codebook".
