Description

Technical Field

[0001] The present application relates to a reference signal transmission method and apparatus in a wireless communication system, and in particular to a method and apparatus for channel quality. Background Art

[0002] With the development of mobile communications, especially the application of 5G active antenna arrays, the architectures of communication and perception systems are converging, and the trend toward integrated communication and perception capabilities within networks is becoming increasingly evident. Integrated communication and perception technology, also known as Integrated Sensing and Communication (ISAC), achieves unified design of communication and perception functions through joint air interface and protocol design, time-frequency and space resource reuse, and hardware device sharing. This enables wireless networks to deliver high-quality communication while simultaneously achieving high-precision and refined perception, thereby improving the system's spectral, energy, and hardware efficiency, achieving integration gain. Furthermore, through mutual assistance and collaboration between communication and perception functions, the performance of each can be enhanced, resulting in coordination gain.

[0003] In the 5G Rel-18 (Release-18) stage, 3GPP (the 3rd Generation Partnership Project) SA1 (Services & Systems Aspects 1) has carried out extensive and comprehensive ISAC scenario use case research; in June 2023, the 3GPP SA#100 plenary meeting adopted the Feasibility Study on Integrated Sensing and Communication (Technical Report, TR) 22.837 (Rel-19), which described the three scenarios of object detection and tracking, environment monitoring, and motion monitoring supported in ISAC, with a total of 32 use cases; in December 2023, the 3GPP RAN (Radio Access Network) #102 plenary meeting adopted the Study on channel modelling for Integrated Sensing and Communication (TSAC). In the Rel-19 phase, the RAN1 Working Group will lead research on ISAC channel modeling, aiming to support object detection and tracking scenarios, using the channel model in 38.901 as a starting point. ISAC is also considered a key potential technology development direction and one of the six main application scenarios in the 6G phase. Summary of the Invention

[0004] When implementing ISAC design based on communication, the system performance measurement indicators are mainly communication performance indicators such as spectrum efficiency, channel capacity, SINR, and bit error performance. Perception functions are supported under the premise of maximizing communication performance. Furthermore, perception-assisted communication can also be implemented, such as obtaining channel quality based on the measurement of perception signals. Therefore, perception-assisted communication in ISAC systems and enhanced channel quality measurement are issues worthy of research.

[0005] In response to the above problems, the present application discloses a solution. It should be noted that, in the description of the above problems, the NR (New Radio) system is used as an example. The present application is also applicable to scenarios such as the future 6G system, achieving technical effects similar to the NR system. Furthermore, although the original intention of the present application is for the ISAC scenario, the present application can also be applied to other non-ISAC scenarios. Furthermore, adopting a unified design solution for different scenarios (such as other non-ISAC scenarios, including but not limited to RIS (Reconfigurable Intelligent Surface), Vehicle to Everything (V2X), SideLink (SL), NCR (Network Control Repeater) capacity enhancement system, short-range communication system, NTN (Non Terrestrial Network), IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) network, etc.) can also help reduce hardware complexity and cost.

[0413] Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The wireless protocol architecture for the control plane 300 between a first communication node device (a UE or RSU (Road Side Unit) in a V2X (Vehicle to Everything) network, a vehicle-mounted device, or a vehicle-mounted communication module) and a second node device (a gNB, a UE or RSU in a V2X network, a vehicle-mounted device, or a vehicle-mounted communication module), or between two UEs, is shown 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 PHY 301 in this article. L2 305 is above PHY 301 and is responsible for the link between the first and second node devices, or between two UEs, through PHY 301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. 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 supports inter-zone mobility of the first communication node device between the second communication node devices. 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 out-of-order 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 between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 in the control plane 300 is responsible for obtaining radio resources (ie, radio bearers) and configuring lower layers using RRC signaling between the second communication node device and the first communication node device.The wireless protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The wireless protocol architecture for the first and second communication node devices in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in L2 355, the RLC sublayer 353 in L2 355, and the MAC sublayer 352 in L2 355. However, the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce wireless transmission overhead. L2 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping QoS (Quality of Service) flows and Data Radio Bearers (DRBs) to support service diversity. Although not shown in the figure, the first communication node device may have several upper layers above L2355, including a network layer (e.g., IP (Internet Protocol) layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0424] Example 4

[0425] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in the attached figure. Figure 4 As shown. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0426] The first communications device 410 includes a controller / processor 475 , a memory 476 , a receive processor 470 , a transmit processor 416 , a multi-antenna receive processor 472 , a multi-antenna transmit processor 471 , a transmitter / receiver 418 , and an antenna 420 .

[0427] The second communication device 450 includes a controller / processor 459 , a memory 460 , a data source 467 , a transmit processor 468 , a receive processor 456 , a multi-antenna transmit processor 457 , a multi-antenna receive processor 458 , a transmitter / receiver 454 and an antenna 452 .

[0428] In transmission from the first communications device 410 to the second communications device 450, at the first communications device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 functionality. In the DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources to the second communications device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second communications device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 (i.e., physical layer). The transmit processor 416 performs coding and interleaving to facilitate forward error correction (FEC) at the second communications device 450, as well as mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-ary phase shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the coded and modulated symbols, including codebook-based and non-codebook-based precoding and beamforming, to generate one or more parallel streams. The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then 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, which is then provided to a different antenna 420.

[0429] During 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 via its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receive processor 456, where the reference signal is used for channel estimation. The data signal is recovered in the multi-antenna receive processor 458 after multi-antenna detection to any parallel stream destined for the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. 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 on the physical channel. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements L2 functionality. 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 DL, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above L2. Various control signals may also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using acknowledgment (ACK) and / or negative acknowledgment (NACK) protocols to support HARQ operations.

[0430] During transmission from the second communications device 450 to the first communications device 410, at the second communications 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 L2. Similar to the transmit functionality at the first communications device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communications device 410, implementing L2 functionality for both the user plane and the control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communications device 410. The transmit processor 468 performs modulation mapping and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting parallel streams into multi-carrier / single-carrier symbol streams. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, these streams are provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a RF symbol stream before providing it to the antenna 452.

[0431] During transmission from the second communication device 450 to the first communication device 410, the functionality at the first communication device 410 is similar to the reception functionality at the second communication device 450 described for transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF signals into baseband signals, and provides the baseband signals to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement L1 functionality. The controller / processor 475 implements L2 functionality. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transmit and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
