Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to reporting schemes and apparatus in wireless communication systems. Background Technology

[0002] In NR (New Radio) systems, as an evolution of MIMO (Multiple-Input Multiple-Output), the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #102 plenary meeting adopted a new WI (Work Item) "NR MIMO Phase 5" for NR (New Radio) Release 19. One of the works includes beam management for FR2 (Frequency Range 2) and sTRP (single Transmitter Receiver Point), as well as intra- and inter-cell beam management. It assumes the use of a unified TCI (Transmission Configuration Indication) and (where possible) utilizes the traditional CSI (Channel State Information) measurement and reporting configuration framework to enhance UE-initiated / event-driven beam management, thereby reducing overhead and / or latency. Summary of the Invention

[0003] In existing systems, for periodic beam reporting, the UE performs beam measurements based on the RS resources configured by the base station. Based on the periodic beam measurement results according to the reporting configuration, the base station can determine the configuration used for reporting and the target beam. For UE-initiated / event-driven beam management, the UE sends beam reports when a trigger event is met. How to determine the trigger event for the reporting needs to be studied.

[0004] To address the aforementioned issues, this application discloses a solution. It should be noted that while the above description uses a 5G network as an example, this application is also applicable to future networks (such as 6G) or other scenarios facing similar problems (e.g., scenarios where link direction changes, or other scenarios supporting multi-level configuration of transmission directions, or scenarios with more capable base stations or user equipment, such as scenarios supporting full-duplex on the same frequency), or for different application scenarios, such as mobile broadband, ultra-reliable low-latency communication, massive machine-type communications, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, and terahertz networks, achieving similar technical effects. Furthermore, adopting a unified solution for different networks or different scenarios (including but not limited to mobile broadband, ultra-reliable low-latency communication, massive machine-type communications, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, and terahertz networks) also helps reduce hardware complexity and cost.

[0247] Example 3

[0248] 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 the attached diagram. Figure 3 As shown.

[0249] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated 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 as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the 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. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in 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.).

[0273] Example 4

[0274] 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 the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0275] 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.

[0276] 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.

[0277] 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.

[0278] 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.

[0279] 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.

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.

[0399] As an example, when the CSI reporting configured by the first information block is periodic, the first node sends a first CSI report on the first physical layer channel. The first CSI report is a single report of the CSI reporting configured by the first information block; the first CSI report occupies a 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 timing in the first timing set; the first timing set includes at least the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource of the first CSI report.

[0400] As an example, the first physical layer channel is PUCCH (Physical uplink control channel) or PUSCH (Physical uplink shared channel).

[0401] As an example, the first physical layer channel is PUCCH.

[0402] Typically, the first physical layer channel occupies one or more symbols in the time domain, and the last symbol of the first physical layer channel is the latest of the one or more symbols occupied by the first physical layer channel.

[0403] Typically, the last symbol refers to the latest symbol, while the first symbol refers to the earliest symbol.

[0404] As an example, the first timing set includes only the latest RS timing of each RS resource in the first RS resource set, which is no later than the CSI reference resource reported by the first CSI.

[0405] As an example, the first timing set includes a third timing set and an RS timing earlier than the third timing set for at least one RS resource in the first RS resource set, wherein the third timing set includes the latest RS timing for each RS resource in the first RS resource set that is no later than the CSI reference resource reported by the first CSI.

[0406] As an example, the CSI processing unit (CPU) is used to process CSI reports.

[0407] As one embodiment, the CSI processing unit is used by the first node to process CSI reports.

[0408] As one example, the CSI processing unit is used to calculate CSI.

[0409] As one embodiment, the CSI processing unit is used by the first node to calculate the CSI.

[0410] Typically, CSI reporting includes beam reporting.

[0411] As an example, the first CSI report is calculated based on the PDSCH (Physical Downlink Shared Channel) on the CSI reference resource reported in the first CSI report.

[0412] As an example, the CSI reference resource reported by the first CSI is the frequency domain resource to which the first CSI report is targeted.

[0413] As an example, the CSI reference resource reported by the first CSI is, in the frequency domain, the subband or wideband to which the first CSI report is targeted.

[0414] As an example, the CSI reference resource reported by the first CSI belongs to the same BWP (Bandwidth Part) in the frequency domain as the frequency domain resource targeted by the first CSI report.

[0415] As an example, the CSI reference resource reported by the first CSI is a first time slot in the time domain, and the first time slot depends on the time slot occupied by the first physical layer channel.

[0416] As an example, the description of the CSI reference resource reported by the first CSI can be found in section 5.2.2.5 of 3GPP TS 38.214.

[0417] As an example, the time slot to which the first physical layer channel belongs is n', and the CSI reference resource reported by the first CSI is a time slot f(n') in the time domain, where f(n') is a function.

[0418] As an example, o is an integer.

[0419] As an example, f(n') is Where μ DL and μ UL These are the downlink and uplink subcarrier spacings, respectively; 'o' is configurable. This indicates a round-down operation.

[0420] As an example, o is Where K offset It is configured by higher-level signaling, n CSI_ref Not less than The minimum value, and μ offset These are all higher-level signaling configurations; for detailed information, please refer to section 5.2.2.5 of 3GPP TS38.214.

[0421] Under the limitations of the above methods or embodiments, the specific algorithm used to calculate the first CSI report is determined by the manufacturer of the first node, or is implementation-related. A typical but non-limiting implementation is described below:

[0422] The first node performs channel measurements on at least one RS resource in the first RS resource set to obtain the channel parameter matrix H. r×P For the channel parameter matrix H r×P Power adjustment is performed, and the adjusted channel parameter matrix is ​​as follows: Where Q is the ratio of the assumed PDSCH EPRE to the NZP CSI-RS EPRE. When using the precoding matrix W...P×l Under these conditions, the precoded channel parameter matrix is: Where l is the rank or the number of layers. In one case, l is a positive integer not greater than P; in another case, the precoding matrix is ​​an identity matrix, in which case P = l. H is calculated using criteria such as SINR (Signal Interference Noise Ratio), EESM (Exponential Effective SINR Mapping), or RBIR (Received Block Mean Mutual Information Ratio). r×P ·W P×l The equivalent channel capacity is calculated, and then the first CSI report is determined from the equivalent channel capacity through methods such as table lookup. Generally, the calculation of the equivalent channel capacity requires the first node to estimate interference (including noise). The first RS resource set includes RS resources for channel measurement and RS resources for interference measurement. The first node can obtain the interference by measuring at least one RS resource in the first RS resource set in this application. Generally, the direct mapping from equivalent channel capacity to CSI depends on receiver performance or hardware-related factors such as modulation scheme.

[0423] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, the first node sends a second CSI report; the second CSI report is a report of the CSI report configured by the first information block.

[0424] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent; wherein, the second CSI report is a single report of the CSI report configured by the first information block; the second CSI report occupies a CSI processing unit from the second symbol to the third symbol; the second symbol is the first symbol of the earliest RS timing in the second timing set; the second timing set includes at least the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource of the second CSI report; the third symbol is the last symbol of the physical layer channel occupied by the second CSI report.

[0425] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent; wherein, the second CSI report is a single report of the CSI report configured by the first information block; the second CSI report occupies CSI processing units from the second symbol to the third symbol; the second symbol is the first symbol of the earliest RS timing in the second timing set; the second timing set includes at least the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource of the second CSI report; the third symbol is the last symbol among M symbols after the second reference symbol, where M is a positive integer; the second reference symbol is the last symbol of the latest RS timing in the second timing set.

[0426] As an example, the physical layer channel occupied by the second CSI report is PUCCH (Physical uplink control channel) or PUSCH (Physical uplink shared channel).

[0427] As an example, the physical layer channel occupied by the second CSI report is PUCCH.

[0428] Typically, the physical layer channel occupied by the second CSI report occupies one or more symbols in the time domain, and the last symbol of the physical layer channel occupied by the second CSI report is the latest one of the one or more symbols occupied by the physical layer channel occupied by the second CSI report.

[0429] Typically, the last symbol refers to the latest symbol, while the first symbol refers to the earliest symbol.

[0430] As an example, the reference timing set includes only the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource reported by the second CSI.

[0431] As an example, the reference timing set includes an RS timing earlier than the fourth timing set and at least one RS resource in the first RS resource set, wherein the fourth timing set includes the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource reported by the second CSI.

[0432] As one embodiment, the second timing set includes only the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource reported by the second CSI.

[0433] As one embodiment, the second timing set includes an RS timing earlier than the fourth timing set and at least one RS resource in the first RS resource set, wherein the fourth timing set includes the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource reported by the second CSI.

[0434] As an example, the second CSI report is calculated based on the PDSCH (Physical Downlink Shared Channel) on the CSI reference resource reported in the second CSI report.

[0435] As an example, the CSI reference resource reported by the second CSI is the frequency domain resource to which the second CSI report is targeted.

[0436] As an example, the CSI reference resource reported by the second CSI is, in the frequency domain, the subband or wideband to which the second CSI report is targeted.

[0437] As an example, the CSI reference resource reported by the second CSI belongs to the same BWP (Bandwidth Part) in the frequency domain as the frequency domain resource targeted by the second CSI report.

[0438] As an example, the CSI reference resource reported by the second CSI is a first time slot in the time domain, and the first time slot depends on the time slot occupied by the first physical layer channel.

[0439] As an example, the description of the CSI reference resource reported by the second CSI can be found in section 5.2.2.5 of 3GPP TS 38.214.

[0440] As an example, the time slot to which the first physical layer channel belongs is n', and the CSI reference resource reported by the second CSI is a time slot f(n') in the time domain, where f(n') is a function.

[0441] As an example, when the CSI report configured by the first information block is event-triggered, the CSI report configured by the first information block occupies the CSI processing unit from the reference symbol to the target symbol; the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes one RS timing for each RS resource in the first RS resource set; the target symbol is a symbol that is no earlier than the reference symbol.

[0442] As an example, when the CSI report configured by the first information block is event-triggered, the CSI report configured by the first information block occupies the CSI processing unit from the reference symbol to the target symbol;

[0443] Wherein, the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes each RS timing of each RS resource in the first RS resource set; the target symbol is a symbol that is no earlier than the reference symbol.

[0444] As an example, measurements of the reference timing set are used to determine whether the triggering event is satisfied.

[0445] As an example, the reference timing set is later than the latest event triggered by the CSI report configured by the first information block.

[0446] As an example, the reference symbol is reported later than the third CSI report, which is the latest event-triggered report of the CSI report configured by the first information block that is earlier than the second CSI report.

[0447] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent; wherein, the second CSI report is a single report of the CSI report configured by the first information block; the second CSI report occupies the CSI processing unit from the reference symbol to the target symbol; the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes one RS timing for each RS resource in the first RS resource set.

[0448] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent; wherein, the second CSI report is a single report of the CSI report configured by the first information block; the second CSI report occupies CSI processing units from the reference symbol to the target symbol; the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes each RS timing of each RS resource in the first RS resource set.

[0449] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent; wherein, the second CSI report is a single report of the CSI report configured by the first information block; the second CSI report occupies CSI processing units from the reference symbol to the target symbol; the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes at least the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource of the second CSI report.

[0450] As an example, the target symbol is the last symbol among the M symbols following the first reference symbol, where M is a positive integer; the first reference symbol is the last symbol of the latest RS timing in the reference timing set.

[0451] As an example, M is predefined.

[0452] As an example, M is configurable.

[0453] As an example, M is reported by the first node to the second node in this application.

[0454] As an example, the M depends on the UE's reporting capability.

[0455] As an example, M represents the UE's reporting capability.

[0456] As an example, M is calculated based on the capabilities reported by the UE.

[0457] As an example, M is the beamReportTiming capability reported by the UE.

[0458] As one example, M depends on the subcarrier spacing.

[0459] As an example, 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 the reference symbol to the target symbol; the method for determining the reference symbol and the target symbol is similar to or the same as the method for determining the start and end symbols of the CSI processing unit occupied by a semi-persistent CSI report (except for the initial semi-persistent CSI report on PUSCH); the higher-level parameter reportQuantity in the IE CSI-ReportConfig configured for the semi-persistent CSI report is set to 'none' and the higher-level parameter trs-Info is not configured in CSI-RS-ResourceSet.

[0460] As an example, when the CSI report configured by the first information block is event-triggered, the CSI report configured by the first information block and a semi-persistent CSI report (except for the initial semi-persistent CSI report on PUSCH) determine the start and end symbols of the occupied CSI processing unit using a similar or identical method. The higher-level parameter reportQuantity in the IE CSI-ReportConfig of the semi-persistent CSI report is set to 'none' and the higher-level parameter trs-Info is not configured in CSI-RS-ResourceSet.

[0461] The advantage of using the above method is that, when determining the CSI processing unit occupied by an event-triggered CSI report, a method similar to or the same as that used in the case of a semi-persistent CSI report (except for the initial semi-persistent CSI report on the PUSCH) is adopted, which simplifies the system design.

[0462] As an example, when the CSI report configured by the first information block is event-triggered, regardless of whether the triggering event is satisfied, the CSI report configured by the first information block occupies the CSI processing unit from the reference symbol to the target symbol.

[0463] As an example, when the CSI report configured by the first information block is event-triggered, the CSI report configured by the first information block occupies the CSI processing unit from the reference symbol to the target symbol; wherein, the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes one RS timing for each RS resource in the first RS resource set; the target symbol is a symbol no earlier than the reference symbol; at least one of the reference timing set or the target symbol depends on whether the triggering event is satisfied.

[0464] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is not satisfied, the target symbol is the last symbol among the M symbols following the first reference symbol, where M is a positive integer; the first reference symbol is the last symbol of the latest RS timing in the reference timing set, which includes one RS timing for each RS resource in the first RS resource set.

[0465] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent; wherein, the second CSI report occupies the CSI processing unit from the reference symbol to the target symbol; the target symbol is the last symbol of the physical layer channel occupied by the second CSI report; the reference symbol is the first symbol of the earliest RS timing in the reference timing set; the reference timing set includes the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource of the second CSI report.

[0466] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is not satisfied, the target symbol is the last symbol among the M symbols following the first reference symbol, where M is a positive integer, the first reference symbol is the last symbol of the latest RS timing in the reference timing set, and the reference timing set includes one RS timing for each RS resource in the first RS resource set;

[0467] When the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent, wherein the second CSI report occupies the CSI processing unit from the reference symbol to the target symbol; the target symbol is the last symbol of the physical layer channel occupied by the second CSI report.

[0468] As an example, when the CSI report configured by the first information block is event-triggered and the triggering event is not satisfied, the reference timing set includes one RS timing for each RS resource in the first RS resource set;

[0469] When the CSI report configured by the first information block is event-triggered and the triggering event is met, a second CSI report is sent, wherein the second CSI report occupies the CSI processing unit from the reference symbol, the reference symbol being the first symbol of the earliest RS timing in the reference timing set, the reference timing set including the latest RS timing of each RS resource in the first RS resource set that is no later than the CSI reference resource of the second CSI report.
