Description

A method and apparatus for measuring CSI-related parameters in nodes used in wireless communication.

[0001] This application claims priority to Chinese Patent Application No. 202411577941.1, filed on November 6, 2024, entitled "A CSI-related Measurement Method and Apparatus Used in a Node for Wireless Communication", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to channel measurement and / or interference measurement and reporting schemes and apparatus in wireless communication systems. Background Technology

[0003] With the development of mobile communication, especially the application of 5G active antenna arrays, the architecture of communication and sensing systems is becoming increasingly consistent, and the trend of integrating communication and sensing capabilities in the network is becoming more and more apparent. Integrated Sensing and Communication (ISAC) technology refers to the unified design of communication and sensing functions through joint design of air interfaces and protocols, multiplexing of time-frequency-space resources, and sharing of hardware devices. This enables the wireless network to achieve high-precision and refined sensing functions while conducting high-quality communication interactions, thereby improving the system's spectral efficiency, energy efficiency, and hardware efficiency, and obtaining integration gain. Furthermore, the mutual assistance and cooperation between communication and sensing functions can also improve each other's performance, thus obtaining coordination gain.

[0004] During the 5G Rel-18 (Release-18) phase, 3GPP (the 3rd Generation Partnership Project) SA1 (Services & Systems Aspects 1) conducted extensive and comprehensive research on ISAC scenario use cases. In June 2023, the 3GPP SA#100 plenary meeting adopted the Technical Report (TR) 22.837 (Rel-19) on Feasibility Study on Integrated Sensing and Communication, which outlined 32 use cases across three major scenarios supported by ISAC: object detection and tracking, environment monitoring, and motion monitoring. In December 2023, the 3GPP RAN (Radio Access Network) #102 plenary meeting adopted the SI (Study on channel modelling for Integrated Sensing And Communication (ISAC) for NR. Item (research project), the RAN1 working group will also focus on supporting object detection and tracking scenarios in the Rel-19 phase, taking the channel model in 38.901 as the starting point, and lead the research on ISAC channel modeling, etc.; ISAC is regarded as one of the key potential technology development directions and six major application scenarios in the 6G phase. Summary of the Invention

[0005] In existing systems, in order to report CSI (Channel State Information), the UE needs to obtain channel measurements and / or interference measurements based on RS (Reference Signal) resources for CSI reporting. Determining whether to send a CSI report is a critical issue. In ISAC, while ensuring communication, sensing capabilities must also be supported. Considering sensing capabilities, the aforementioned issues need to be addressed.

[0006] To address the aforementioned issues, this application discloses a solution. It should be noted that, in the description of this application, only an NR (New Radio) system is used as an example; this application is also applicable to scenarios such as future 6G systems, achieving similar technical effects to NR systems. Furthermore, although the initial intention of this application is for ISAC scenarios, it can also be applied to other non-ISAC scenarios. Furthermore, adopting a unified design scheme for different scenarios (such as other non-ISAC scenarios, including but not limited to Vehicle to Everything (V2X), SideLink (SL), RIS (Reconfigurable Intelligent Surface), NCR (Network Control Repeater) capacity enhancement systems, short-range communication systems, NTN (Non-Terrestrial Network), IoT (Internet of Things), and URLLC (Ultra-Reliable Low Latency Communication) networks, etc.) also helps to reduce hardware complexity and cost. Without conflict, embodiments and features in any node of this application can be applied to any other node. Where there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other arbitrarily.

[0402] Example 3

[0403] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in Figure 3.

[0404] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and control plane according to this application, as shown in Figure 3. 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 3 shows the radio protocol architecture for the control plane 300 between a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X), or between two UEs, using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. Layer 1 will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first communication node device and the second communication node device, or between two UEs. Layer 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, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between the second communication node devices and the first communication node device. The RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first communication node devices. Furthermore, the MAC sublayer 302 handles HARQ operations. In the control plane 300, the Radio Resource Control (RRC) sublayer 306 of Layer 3 (L3) is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second and first communication node devices. The user plane 350's radio protocol architecture includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second communication node devices in the user plane 350 is largely the same as the corresponding layers and sublayers in the control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 Layer 355, RLC sublayer 353 in L2 Layer 355, and MAC sublayer 352 in L2 Layer 355. However, 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, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0429] Example 4

[0430] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in Figure 4. 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.

[0431] 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.

[0432] 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.

[0433] 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 L2 layer, 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 operation, 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more parallel streams. 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 domains, and subsequently uses 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 the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0434] 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 parallel stream destined for the second communication device 450. Symbols on each parallel 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 DL (Downlink), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer 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. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0435] 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 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, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of 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 parallel 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.

[0436] 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. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels 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 operation.

[0452] For the first node U1, in step S5101, the first information block is received; in step S5102, the third information block is received; in step S5103, the first CSI reporting configuration is received; in step S5104, the first CSI report is sent; and in step S5105, the sending of the first CSI report is abandoned.

[0453] For the second node N2, a first information block is sent in step S5201; a third information block is sent in step S5202; a first CSI reporting configuration is sent in step S5203; and the first CSI report is received in step S5204.

[0454] In Embodiment 5, the first information block is used to determine a reference time-domain resource set; the first CSI reporting configuration indicates a first RS resource set, the first RS resource set including one or more RS resources; whether the first CSI report is sent depends on whether at least one RS resource in the first RS resource set includes a transmission timing no later than the CSI reference resource reported by the first CSI and satisfies a first condition; the first condition includes orthogonality between the time domain and the reference time-domain resource set; when the first CSI report is sent, a first timing set is used for at least one of the channel measurement or interference measurement reported by the first CSI, the first timing set including at least one transmission timing of at least one RS resource in the first RS resource set no later than the CSI reference resource reported by the first CSI and satisfying the first condition.

[0459] As an example, the monitoring refers to coherent detection, that is, coherent reception of the RS sequence of the DMRS of the physical layer channel where the first CSI resides, and measurement of the energy of the signal obtained after coherent reception. When the energy of the signal obtained after coherent reception is greater than a first given threshold, the second node determines that the first CSI report has been sent; otherwise, the second node determines that the first CSI report has not been sent or has been incorrectly received.

[0460] As one embodiment, the monitoring refers to energy detection, that is, obtaining the received energy by measuring the energy of the wireless signal and averaging it over time. When the received energy is greater than a second given threshold, the second node determines that the first CSI report has been sent; otherwise, the second node determines that the first CSI report has not been sent or has been incorrectly received.

[0461] As one embodiment, the second node receives the first CSI report, or chooses not to receive the first CSI report; wherein, whether the first CSI report is received depends on whether at least one RS resource in the first RS resource set includes the CSI reference resource no later than the first CSI report and whether the transmission timing satisfies the first condition.
