Description

Technical Field

[0001] This application relates to a reference signal transmission method and apparatus in a wireless communication system, and particularly to a method and apparatus for path loss. 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 consistent, and the integrated trend of communication and sensing capabilities in the network is gradually becoming apparent. The integrated communication and sensing technology, that is, the integrated sensing and communication (ISAC) technology, refers to realizing 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, obtaining integration gain. In addition, by mutually assisting and collaborating between the communication and sensing functions, the performance of each other can be improved, and thus 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, 32 use cases in three major scenarios, namely object detection and tracking, environment monitoring, and motion monitoring, supported in ISAC were elaborated in the Technical Report (TR) 22.837 (Rel-19) of the Feasibility Study on Integrated Sensing and Communication passed by the 3GPP SA #100 plenary session; in December 2023, the 3GPP RAN (Radio Access Network) #102 plenary session passed the SI (Study Item) of the Study on channel modelling for Integrated Sensing And Communication (ISAC) for NR. The RAN1 working group will also aim to support the object detection and tracking scenario and will lead research on ISAC channel modelling starting from the channel model in 38.901 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 a wireless communication system, the power divergence of radio signals and the wireless propagation environment between the transmitter and receiver can cause path loss. Link budget is an important tool for wireless system design, and path loss is one of the main factors affecting the link budget. In NR, the UE (User Equipment) obtains the path loss value by calculating the difference between the transmission power of the reference signal and the RSRP (Reference Signal Received Power); among them, the RSRP is the RSRP based on higher layer filtering to avoid excessive fluctuations in the link budget caused by frequent or drastic changes in path loss. However, the existence of the filter coefficient during higher layer filtering makes the RSRP of higher layer filtering may be affected by extreme values or outliers for a long time.

[0005] Compared with a communication system alone, the sensing system in ISAC can achieve rapid sensing of the distance, position, moving speed, etc. of target nodes, and then can determine the wireless propagation environment in different beam directions, such as whether there is a short-term beam blockage on the UE's moving route, etc.; the communication system in ISAC can timely adjust the communication configuration based on the sensing results, such as optimizing the calculation of path loss to reduce the increase in uplink transmission power caused by short-term beam blockage. Therefore, enhancing the calculation of path loss with the help of sensing results in the ISAC scenario and then improving the stability and reliability of the system is an issue worthy of research.

[0006] In view of 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 taken as an example, and the present application is also applicable to scenarios such as future 6G systems and can achieve technical effects similar to those of 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 solution for different scenarios (such as other non-ISAC scenarios, including but not limited to Reconfigurable Intelligent Surface (RIS), Vehicle to Everything (V2X), SideLink (SL), Network Control Repeater (NCR) capacity enhancement system, short-range communication system, Non Terrestrial Network (NTN), Internet of Things (IoT), Ultra Reliable Low Latency Communication (URLLC) network, etc.) is also helpful for reducing hardware complexity and cost.

[0406] 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 the first communication node device (UE or RSU (Road Side Unit) in V2X (Vehicle to Everything), in-vehicle device or in-vehicle communication module) and the 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 of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using the 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). For the radio protocol architecture in the user plane 350 used for the first communication node device and the second communication node device, the corresponding layers and sub-layers in the control plane 300 are substantially the same 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 the diversity of services. 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.).

[0420] Example 4

[0421] Embodiment 4 exemplifies 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 appendix Figure 4 shown. The appendix Figure 4 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.

[0422] 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.

[0423] 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.

[0424] 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 the functions of L2. 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 for 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, 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 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.

[0425] 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 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 provided 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 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 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 channels, 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.

[0426] 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 transmission 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 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.

[0427] 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 receiving 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals 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 ACK and / or NACK protocols to support HARQ operations.
