Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a channel measurement and / or interference measurement and reporting scheme and device in a wireless communication system. Background Art

[0002] With the development of mobile communications, especially the application of 5G active antenna arrays, the architecture of communication systems and perception systems are becoming more consistent, and the integration trend of communication and perception capabilities in the network is becoming increasingly obvious. Communication and perception integration technology, also known as Integrated Sensing And Communication (ISAC) technology, refers to the unified design of communication and perception functions through joint design of air interfaces and protocols, reuse of time-frequency and space resources, and sharing of hardware devices, so that wireless networks can achieve high-precision and refined perception functions while performing high-quality communication interactions, thereby improving the system's spectrum efficiency, energy efficiency, and hardware efficiency, and obtaining integration gain. In addition, through the mutual assistance and cooperation between the two functions of communication and perception, the performance of each other can be improved, thereby obtaining coordination gain.

[0003] In the 5G Rel-18 (Release-18, Version-18) stage, 3GPP (the 3rd Generation Partnership Project) SA1 (Services & Systems Aspects 1, Services and Systems 1) has carried out extensive and comprehensive ISAC scenario use case research; in June 2023, the Feasibility Study on Integrated Sensing and Communication (Technical Report, TR) 22.837 (Rel-19) passed by the 3GPP SA#100 Plenary Meeting described the three major 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, Radio Access Network) #102 Plenary Meeting passed the Study on channel modelling for Integrated Sensing and Communication (Technical Report, TR) 22.837 (Rel-19) In the Rel-19 stage, the RAN1 working group will also aim to support object detection and tracking scenarios, taking the channel model in 38.901 as the starting point, and lead the research on ISAC channel modeling. ISAC is regarded as the key potential technology development direction and one of the six main application scenarios in the 6G stage. Summary of the invention

[0004] In the existing system, in order to report CSI (Channel State Information), UE needs to obtain channel measurement and / or interference measurement for CSI reporting based on RS (Reference Signal) resources, among which how to determine the transmission timing of RS resources for channel and / or interference measurement is a key issue. In ISAC, while ensuring communication, it is also necessary to support perception capabilities. Taking perception into consideration, the above issues need to be considered.

[0005] In view of the above problems, the present application discloses a solution. It should be noted that in the description of the present application, only the NR (New Radio) system is used as an example. The present application is also applicable to scenarios such as the future 6G system, and obtains technical effects similar to 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, for different scenarios (such as other non-ISAC scenarios, including but not limited to vehicle networking (Vehicle to Everything, V2X), side link (SideLink, SL), RIS (Reconfigurable Intelligent Surface, reconfigurable intelligent super surface), NCR (Network Control Repeater, network control repeater) capacity enhancement system, short-range communication system, NTN (Non Terrestrial Network, non-terrestrial network), IoT (Internet of Things, Internet of Things), URLLC (Ultra Reliable Low Latency Communication, ultra-robust low-latency communication) network, etc.), a unified design scheme is also helpful to reduce hardware complexity and cost.

[0309] Under the limitations of the above method or example, the specific algorithm for calculating the first CSI report is determined by the manufacturer of the first node itself, or is implementation-related. The following describes a typical but non-limiting implementation:

[0310] The first CSI report includes a first resource indication and a CQI. The first resource indication indicates a first RS resource, and the first RS resource is one RS resource in the first RS resource set; at least one transmission opportunity of the CSI reference resource that is not later than the first CSI report for the first RS resource belongs to the first opportunity set; the first node first performs measurements on the first opportunity set to obtain a channel parameter matrix H r×t , where r and t are the number of receiving antennas and the number of antenna ports of the first RS resource respectively; perform power adjustment on the channel parameter matrix H r×t , and the adjusted channel parameter matrix is where P is the assumed ratio of PDSCH EPRE to CSI-RS EPRE; under the condition of adopting the precoding matrix W t×l the precoded channel parameter matrix is where l is the number of ranks or layers. In one case, l is a positive integer not greater than t. In another case, the precoding matrix is the identity matrix, and at this time t = l; criteria such as SINR (Signal Interference Noise Ratio), EESM (Exponential Effective SINR Mapping), or RBIR (Received Block mean mutual Information Ratio) are used to calculate the equivalent channel capacity of H r×t ·W t×l Then, the CQI included in the first CSI report is determined by looking up a table or other means based on the equivalent channel capacity. Generally speaking, the calculation of the equivalent channel capacity requires the first node to estimate interference (including noise). The first CSI report configuration also indicates the RS resources for interference measurement. The first node can measure one or more transmission opportunities of the RS resources for interference measurement to obtain accurate measured interference. Generally speaking, the direct mapping from the equivalent channel capacity to the CQI value depends on receiver performance or hardware-related factors such as the modulation method.

[0398] Example 4

[0399] Example 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 appendix. Figure 4 shown in 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.

[0400] 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.

[0401] 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.

[0402] 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 functionality of the L2 layer. 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 the L1 layer (i.e., the physical layer). The transmit processor 416 implements coding 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-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital space precoding on the coded 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 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.

[0403] 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 respective 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 the L1 layer. 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 the L2 layer. 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 (DownLink), 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 the L2 layer. Various control signals may also be provided to the 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.

[0404] 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 the L2 layer. Similar to the transmit function at the first communication device 410 described in DL, the controller / processor 459 performs 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 layer 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.

[0405] 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 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 the L1 layer. A 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 a computer-readable medium. The controller / processor 475 provides demultiplexing between the 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.
