Description

A method and apparatus for measuring CSI in a node for wireless communication

[0001] This application claims priority to a Chinese patent application filed with the Patent Office of China on March 19, 2024, with application number 202410317094.9 and invention name “A method and device for CSI measurement in a node used for wireless communication”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a CSI (Channel State Information) measurement scheme and apparatus in a wireless communication system. Background Art

[0003] In wireless communication systems supporting MIMO (Multiple-Input Multiple-Output), it is a common technique for user equipment (UE) to generate and feed back CSI (Channel Status Information) based on channel and / or interference measurements to assist the base station in multi-antenna processing. In 5G (the 5th generation) NR (new radio) systems, to enable the base station to obtain accurate CSI, the base station configures the UE with NZP (Non-Zero Power) CSI-RS (Channel State Information Reference Signal) resources for channel measurement and CSI-IM (Channel State Information–Interference Measurement) resources for interference measurement. In addition, NZP CSI-RS resources can also be configured for interference measurement. In the existing 3GPP Release 18 and earlier versions, the base station configures or indicates RS (reference signal) resources for CSI measurement, and the base station configures or indicates time-frequency resources for carrying CSI reporting. The UE sends CSI reports on the time-frequency resources configured or indicated by the base station.

[0004] To improve coverage and achieve greater spectrum efficiency, the 3GPP (3rd Generation Partnership Project) RAN#94 meeting approved the "NR MIMO Phase 5" work item (WI). To reduce CSI reporting overhead and / or CSI latency, the design of UE-initiated / event-driven CSI measurement and reporting is a key issue to be addressed. Summary of the Invention

[0005] In existing systems, the number of simultaneous CSI calculations a UE can support is limited. The CSI processing units occupied by periodic, semi-persistent, or aperiodic CSI reporting are clearly defined in the communications standards. Determining the CSI processing units occupied by UE-initiated or event-driven CSI reporting requires further study.

[0006] In response to the above problems, the present application discloses a solution. It should be noted that although the above description uses 5G network as an example, the present application is also applicable to future networks (such as 6G, etc.) or other scenarios facing similar problems (for example, there are scenarios where the link direction changes, or other scenarios that support multi-level configuration of transmission direction, or base stations or user equipment with stronger capabilities, such as scenarios that support full-duplex at the same frequency, or for different application scenarios, such as mobile broadband, ultra-reliable low-latency communication, large-scale machine communication, non-terrestrial network, synaesthesia integrated network, smart metasurface, terahertz network, similar technical effects can also be achieved. In addition, the use of a unified solution for different networks or different scenarios (including but not limited to mobile broadband, ultra-reliable low-latency communication, large-scale machine communication, non-terrestrial network, synaesthesia integrated network, smart metasurface, terahertz network scenarios) also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments of any node in the present application and the features in the embodiments can be applied to any other node, and vice versa. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.

[0008] Receive a first information block; the first information block configures a CSI report, where the CSI report configured by the first information block is periodic or event-triggered;

[0009] Receiving RS in a first RS resource set; the first RS resource set includes one or more RS resources;

[0010] In which, when the CSI reporting configured by the first information block is periodic, the first RS resource set is used for at least one of the channel measurement or interference measurement of the CSI reporting configured by the first information block; when the CSI reporting configured by the first information block is event-triggered, the CSI reporting configured by the first information block is triggered only when the triggering event is met, and the triggering event depends on the measurement of the first RS resource set; the CSI processing unit occupied by the CSI reporting configured by the first information block depends on whether the CSI reporting configured by the first information block is periodic or event-triggered.

[0011] As an embodiment, the problem to be solved by the present application includes: a CSI processing unit occupied by an event-triggered (in other words, UE-initiated / event-driven) CSI reporting.

[0012] As an embodiment, the advantage of adopting the above method is that it has good compatibility with the standard and makes minor changes to the standard.

[0013] As an embodiment, the advantage of adopting the above method is that it has high flexibility and simplifies the design.

[0014] As an embodiment, the advantage of adopting the above method is that, for different CSI reporting types (periodic or event-triggered), appropriate CSI processing units are occupied.

[0015] As an embodiment, the benefit of adopting the above method is that the system performance is improved.

[0016] As an embodiment, the advantage of adopting the above method is that it not only supports the CSI reporting type in the current standard, but also supports event-triggered CSI reporting.

[0017] According to one aspect of the present application, the invention comprises:

[0018] When the CSI report configured by the first information block is periodic, sending a first CSI report on a first physical layer channel;

[0019] The first CSI report is a single report of the CSI report configured by the first information block; the first CSI report occupies the CSI processing unit from the first symbol to the last symbol of the first physical layer channel; the first symbol is the first symbol of the earliest RS opportunity in the first opportunity set; the first opportunity set includes at least the latest RS opportunity of each RS resource in the first RS resource set that is no later than the CSI reference resource of the first CSI report.

[0020] According to one aspect of the present application, the invention comprises:

[0021] When the CSI report configured by the first information block is event-triggered and the triggering event is satisfied, sending a second CSI report;

[0022] The second CSI reporting is a reporting of the CSI reporting configured by the first information block.

[0023] According to one aspect of the present application, when the CSI report configured by the first information block is event-triggered, the CSI report configured by the first information block occupies a CSI processing unit from a reference symbol to a target symbol;

[0024] The reference symbol is the first symbol of the earliest RS opportunity in the reference opportunity set; the reference opportunity set includes an RS opportunity for each RS resource in the first RS resource set; and the target symbol is a symbol that is not earlier than the reference symbol.

[0030] As an embodiment, the advantage of adopting the above method is that it has high flexibility and simplifies the design.

[0031] As an embodiment, the advantage of adopting the above method is that, for event-triggered CSI reporting, the method for determining the end symbol of the occupied CSI processing unit is different from the method in the case of periodic CSI reporting, and is applicable to the characteristic that event-triggered CSI reporting is only sent when the triggering event is met.

[0032] As an embodiment, the advantage of adopting the above method is that, for different CSI reporting types (periodic or event-triggered), different CSI processing unit occupation methods are adopted, which are suitable for different CSI reporting characteristics.

[0033] According to one aspect of the present application, when the CSI report configured by the first information block is event triggered, regardless of whether the triggering event is met, the CSI report configured by the first information block occupies the CSI processing unit from the reference symbol to the target symbol.

[0034] As an embodiment, the advantage of adopting the above method is that, for event-triggered CSI reporting, the occupancy of the CSI processing unit is not affected by whether the triggering event is satisfied. The feature that the event-triggered CSI report is sent only when the triggering event is satisfied also simplifies the design and makes minimal changes to the standard.

[0035] According to one aspect of the present application, at least one of the reference opportunity set or the target symbol depends on whether the triggering event is satisfied.

[0036] As an embodiment, the advantage of adopting the above method is that, for event-triggered CSI reporting, the occupancy of the CSI processing unit is related to whether the triggering event is satisfied. In both cases where the triggering event is satisfied and not satisfied, the CSI processing unit can be occupied more accurately, thereby reducing excessive occupancy of the CSI processing unit.

[0173] Embodiment 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to an embodiment of the present application, as shown in FIG3 .

[0174] Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in FIG3 . FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the radio protocol architecture of the control plane 300 for communication 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305, located above PHY 301, is responsible for the link between the first communication node device and the second communication node device, or between two UEs. The L2 layer 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. The PDCP sublayer 304 also provides security by encrypting data packets, and provides support for 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. 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 Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring 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 layer) and Layer 2 (L2 layer).

However, the 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. The SDAP sublayer 356 is responsible for mapping between QoS 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 the L2 layer 355, including a network layer (e.g., an IP 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.).

[0196] Example 4

[0197] 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 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.

[0198] 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 .

[0199] 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 .

[0200] 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 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 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 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, as well as 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), and M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming on the coded and modulated symbols to generate one or more parallel streams. The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with reference signals (e.g., pilots) in the time and / or frequency domains, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. The 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 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.

[0201] During transmission from the first communications device 410 to the second communications device 450, each receiver 454 receives a signal at the second communications device 450 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 undergoes multi-antenna detection in the multi-antenna receive processor 458 to recover any parallel streams destined for the second communications 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 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 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 the L2 layer. Various control signals may also be provided to the L3 layer for L3 processing. The controller / processor 459 is also responsible for error detection using an acknowledgement (ACK) and / or negative acknowledgement (NACK) protocol to support HARQ operations.

[0202] 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 the L2 layer. 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 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 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.

[0203] 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 layer functionality. The controller / processor 475 implements L2 layer 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.
