Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a method and apparatus for reference signal transmission. Background Art

[0002] With the development of mobile communication, especially the application of 5G active antenna arrays, the architectures of communication systems and sensing systems tend to be the same, and the trend of integrating communication and sensing capabilities in the network becomes increasingly obvious. The integrated communication and sensing technology, that is, the integrated sensing and communication (ISAC) technology, refers to the unified design of communication and sensing functions through means such as joint design of the air interface and protocols, time-frequency-space resource reuse, and sharing of hardware devices, enabling the wireless network to achieve high-precision and refined sensing functions while performing high-quality communication interactions, thereby improving the spectral efficiency, energy efficiency, and hardware efficiency of the system and obtaining an integration gain. In addition, by assisting and collaborating with each other between the two functions of communication and sensing, the performance of each other can be improved, and thus a coordination gain can be obtained.

[0003] In the 5G Rel-18 (Release-18) phase, the 3GPP (the 3rd Generation Partnership Project) SA1 (Services & Systems Aspects 1) has carried out extensive and comprehensive research on ISAC scenario use cases; in June 2023, the Technical Report (TR) 22.837 (Rel-19) of Feasibility Study on Integrated Sensing and Communication, which was adopted by the 3GPP SA #100 plenary session, elaborated 32 use cases in three major scenarios supported in ISAC, namely object detection and tracking, environment monitoring, and motion monitoring; in December 2023, the 3GPP RAN (Radio Access Network) #102 plenary session adopted the SI (Study Item) of Study on channel modelling for Integrated Sensing And Communication (ISAC) for NR. The RAN1 working group will also take the object detection and tracking scenario as the goal and the channel model in 38.901 as the starting point to lead the research on ISAC channel modelling and other aspects in the Rel-19 phase; ISAC is also regarded as one of the key potential technology development directions and six major application scenarios in the 6G phase. Summary of the Invention

[0004] In ISAC, the sensing mode can be divided into monostatic sensing with collocated transceiver and bistatic sensing with separated transceiver. In the case of monostatic sensing, the same node performs the transmission and reception of sensing signals, and the node performing the transmission and reception of sensing signals can be a base station or a UE (User Equipment). In bistatic sensing, the transmission and reception of sensing signals are performed by two spatially separated nodes, and the two nodes can be two base stations, two UEs, or one base station and one UE.

[0005] In single - station sensing where the transceiver is collocated, i.e., the receiving and transmitting nodes are the same, the node that executes the transmission and reception of the sensing signal needs to receive the reflected echo of the sensing signal after transmitting the sensing signal. There will be a two - way transmission delay between the sensing signal and the reflected echo; in bistatic sensing where the transceiver is separated, i.e., the receiving and transmitting nodes are spatially separated, there will also be a transmission delay between the sensing signal received by the receiving node and / or the waveform signal of the sensing signal after being reflected, diffracted or refracted by the sensing target and the reference timing of the receiving node. Therefore, the transmission delay interval for the receiving antenna in the ISAC system to monitor the sensing signal and / or the reflected echo of the sensing signal is an issue worthy of study.

[0006] In response to the above problems, the present application discloses a solution. It should be noted that in the above problem description, the NR (New Radio) system is used as an example. The present application is also applicable to scenarios such as future 6G systems and achieves similar technical effects as the NR system; further, 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; further, adopting a unified design scheme for different scenarios (such as other non - ISAC scenarios, including but not limited to RIS (Reconfigurable Intelligent Surface), vehicle - to - everything (V2X), side - link (SL), network control repeater (NCR) capacity - enhanced systems, short - range communication systems, non - terrestrial network (NTN), Internet of Things (IoT), ultra - reliable low - latency communication (URLLC) networks, etc.) helps to reduce hardware complexity and cost.

[0360] Example 3

[0361] Example 3 illustrates a schematic diagram of an embodiment of the radio protocol architecture of the user plane and the control plane according to an embodiment of the present application, as shown in the appendix Figure 3 as shown.

[0362] Figure 3 is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and the control plane 300, Figure 3Show the radio protocol architecture of the control plane 300 for a first communication node device (UE or RSU (Road Side Unit) in V2X (Vehicle to Everything), in-vehicle device or in-vehicle communication module) and a second node device (gNB, UE or RSU in V2X, in-vehicle device or in-vehicle communication module), or between two UEs, 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 node device and the second node device, or between two UEs, through PHY 301. 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, and these sublayers 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 provides handover support for 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 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 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 (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second communication node device and the first communication node device.The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first communication node device and the second communication node device in the user plane 350 is substantially the same as the corresponding layers and sub-layers in the control plane 300 for the physical layer 351, the PDCP sub-layer 354 in L2 355, the RLC sub-layer 353 in L2 355, and the MAC sub-layer 352 in L2 355. However, the PDCP sub-layer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The L2 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sub-layer 356. The SDAP sub-layer 356 is responsible for the mapping between QoS (Quality of Service) flows and data radio bearers (DRBs) to support service diversity. Although not shown, the first communication node device may have several upper layers above L2 355, including a network layer (e.g., an IP (Internet Protocol) layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.).

In the DL, 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 HARQ operations, 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 L1 (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-ary phase shift keying (M-PSK), M-ary 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 parallel streams. The transmit processor 416 then maps each parallel stream to subcarriers, multiplexes the modulated symbols with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses an 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 a different antenna 420.

[0380] 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 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 multi-carrier symbol stream and provides it to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of L1. 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 parallel streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each parallel stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 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. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of L2. 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 the transmission and the logical channel, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the core network. Subsequently, the upper layer data packets are 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 the Acknowledgement (ACK) and / or Negative Acknowledgement (NACK) protocols to support HARQ operations.

[0381] 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 a controller / processor 459. The data source 467 represents all protocol layers above L2. Similar to the transmit function at the first communication device 410 described in 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 communication device 410, and implements L2 functions for 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 communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing. 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 parallel streams into multi-carrier / single-carrier symbol streams, and after passing through analog precoding / beamforming operations in the multi-antenna transmit processor 457, provides them 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.

[0382] 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 functions 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 the functions of L1. A controller / processor 475 implements L2 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. The controller / processor 475 provides demultiplexing between transport 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 the ACK and / or NACK protocols to support HARQ operations.
