[0003] In 5G 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 targeting 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 Indicator) and makes full use of the traditional CSI (Channel State Information) measurement and reporting configuration framework to enhance UE-initiated / event-driven CSI reporting, thereby reducing overhead and / or latency. Summary of the Invention

[0217] Example 3

[0218] 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.

[0219] 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.).

[0230] Example 4

[0231] 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.

[0232] 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.

[0233] 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.

[0234] 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 DL (Downlink), 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 L1 layer (i.e., 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), and M-quadrature amplitude modulation (M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more parallel... The 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 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 multicarrier symbol stream provided by the multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0235] 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 over the physical channel by the first communication device 410. 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 (L2). 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 (Layered Logic), 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 (L3) for L3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0236] 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.

[0237] 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.

[0251] Example 5

[0252] Example 5 illustrates a transmission flowchart according to an embodiment of this application, as shown in Figure 5. In Figure 5, the first node U01 and the second node N02 are two communication nodes transmitting via an air interface, and the steps in the dashed boxes F51 and F52 are optional.

[0253] For the first node U01, in step S5101, M CSI reporting configurations are received; in step S5102, RSs are received from the M RS resource sets respectively; in step S5103, a first information block is sent on the first PUCCH; in step S5104, a first DCI is received; in step S5105, a second information block and only M1 CSI reports from the M CSI reports are sent on the first PUSCH.

[0254] For the second node N02, in step S5201, M CSI reporting configurations are sent; in step S5202, RSs are sent in the M RS resource sets respectively; in step S5203, a first information block is received on the first PUCCH; in step S5204, a first DCI is sent; in step S5205, a second information block and only M1 CSI reports from the M CSI reports are received on the first PUSCH.

[0255] In Embodiment 5, the first information block requests PUSCH resources to carry at least one of the M CSI reports, where M is a positive integer greater than 1; the first DCI schedules the first PUSCH, and the first DCI triggers the M CSI reports; M1 is a positive integer less than M; wherein, the second information block indicates the M1 CSI reports; the M CSI reports are all event-triggered reports, and only the triggering events of the M1 CSI reports are satisfied.

[0256] As an example, in the above method, the base station triggers M events to trigger CSI reporting, and the UE indicates and sends M1 CSI reports in which only the triggering events are satisfied. The advantages include: when sending the DCI scheduling, the base station does not need to know precisely which of the M CSI reports have their triggering events satisfied, i.e., which CSIs the UE actually needs to report. Thus, when designing the DCI, the base station only needs to indicate all M CSI reports, without traversing all possible combinations, thereby simplifying the design of the DCI scheduling and saving DCI overhead.

[0448] As one example, how the given CSI report is generated is determined by the manufacturer of the first node, or is implementation-dependent. Some typical but non-limiting implementations are described below:

[0449] In one implementation, the first node obtains the L1-RSRP based on channel measurements of RS resources in the given RS resource set. Typically, whether the L1-RSRP is filtered, or the filtering algorithm, is determined by the manufacturer of the first node, or is implementation-dependent; it can be implemented using an algorithm or in hardware.

[0450] In another implementation, the first node obtains multiple L1-RSRPs based on channel measurements of multiple RS resources in the given RS resource set, each L1-RSRP corresponding to a different RS resource in the given RS resource set. The first node selects at least one L1-RSRP from the multiple L1-RSRPs, and the given CSI report indicates the RS resource corresponding to each of the at least one L1-RSRP. The selection of the at least one L1-RSRP can be done in various ways, such as selecting the largest value, random selection, determination by the manufacturer of the first node, or implementation-related selection.

[0451] In another implementation, the first node obtains multiple L1-RSRPs based on channel measurements of multiple RS resources in the given RS resource set, each L1-RSRP corresponding to a different RS resource in the given RS resource set. The first node selects RS resources from the multiple RS resources whose corresponding L1-RSRPs satisfy certain conditions and indicates the selected RS resources in the given CSI report.

[0452] In another implementation, the first node obtains an RS resource channel parameter matrix H by performing channel measurements on the RS resources in the given RS resource set. r×P ; when using the precoding matrix W P×l Under these conditions, the precoded channel parameter matrix is ​​H r×P ·W P×l 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-to-Noise and Interference 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 given CSI is reported using methods such as table lookup based on the equivalent channel capacity. Generally, the calculation of the equivalent channel capacity requires the first node to estimate the interference (including noise), and the first node obtains the interference by measuring the interference in the RS resources of the given RS resource set. Typically, the mapping from the equivalent channel capacity to the CSI depends on receiver performance or hardware-related factors such as modulation scheme.

[0453] For cases where channel parameter matrices are obtained for multiple RS resources in a given RS resource set through channel measurement, one implementation method is to obtain the equivalent channel capacity for each RS resource using the above method, select the RS resource corresponding to the largest equivalent channel capacity, and indicate this RS resource in the given CSI report.
