Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to methods and apparatus for transmitting wireless signals in non-terrestrial network communication systems. Background Technology

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

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

[0004] After introducing PUSCH transmission with orthogonal sequences, enhancing UCI multiplexing on the PUSCH is a crucial issue to consider in system design optimization; this application discloses a solution to this problem. It should be noted that this application is applicable to various wireless communication scenarios, such as non-terrestrial network (NTN) and terrestrial network (TN) communication scenarios, achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to non-terrestrial network and terrestrial network communication scenarios) helps reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any embodiment of this application can be arbitrarily combined with each other.

Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for control plane 300 is illustrated using 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 document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the links between the first and second communication node devices and between the two UEs via PHY301. L2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the 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 through encrypted data packets and provides cross-area mobility support.

[0228] Example 4

[0229] Example 4 shows schematic diagrams 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 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0230] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0231] 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.

[0232] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. 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 to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters 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)). 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. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an inverse fast fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0233] 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 a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier 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 receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the second communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the first communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0234] 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 upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions 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, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0235] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the 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 computer-readable media. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

In the appendix Figure 7 In cases (a) and (b), a PUSCH applying the first type of orthogonal sequence refers to a rectangle filled with diagonal lines and a rectangle filled with cross lines, both of which represent a portion of the PUSCH; in the appendix Figure 7In case (c), a rectangle filled with diamond lines indicates that the PUSCH carries a DM-RS symbol, while rectangles filled with diagonal lines and cross lines both indicate that the PUSCH does not carry a DM-RS symbol. A PUSCH using the first type of orthogonal sequence consists of each rectangle filled with diagonal lines, each rectangle filled with cross lines, and each rectangle filled with diamond lines. Each of these three patterns represents a symbol occupied by the PUSCH in the time domain. (The remaining text appears to be incomplete and requires further context.) Figure 7 In case (d), a PUSCH using the first type of orthogonal sequence consists of rectangles filled with diagonal lines and rectangles without filler; each of these three patterns of filled rectangles represents a subcarrier occupied by this PUSCH in the frequency domain; in the appendix Figure 7 In these four cases, the rectangle with thicker lines represents the first UCI that is reused.

This PUSCH is transmitted across repetition #0 and repetition #1. The first type of orthogonal sequence includes two elements, which are applied in repetition #0 and repetition #1, respectively. The first UCI is multiplexed onto this PUSCH and is transmitted across repetition #0 and repetition #1.

[0322] As a sub-example of the above embodiment, both repetition #0 and repetition #1 are nominal repetitions.

[0323] As a sub-example of the above embodiment, both repetition #0 and repetition #1 are actual repetitions.

[0324] As an example, a PUSCH applying the first type of orthogonal sequence includes: the PUSCH applying the first type of orthogonal sequence between symbols.
