Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a transmission method and apparatus for a CSI processing unit and CSI reporting in a wireless communication system. Background Art

[0002] In a wireless communication system supporting MIMO (Multiple-Input Multiple-Output), it is a common technique for a UE (User Equipment) to generate and feedback CSI (Channel State Information) based on channel and / or interference measurements to assist the base station in multi-antenna processing. In the 5G (the 5th generation) NR (New Radio) system, in order for the base station to obtain accurate CSI, the base station configures 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 for the UE. In addition, NZP CSI-RS resources for interference measurement can also be configured.

[0003] In the 5G system, as an evolution of MIMO (Multiple-Input Multiple-Output), the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #102 plenary session adopted a new WI (Work Item) of NR Release 19, "NR MIMO Phase 5". One of the tasks includes beam management for FR2 (Frequency Range 2) and sTRP (single Transmitter Receiver Point), as well as intra- and inter-cell beam management. It is assumed that a unified TCI (Transmission Configuration Indicator) is used, and the traditional CSI measurement and reporting configuration framework is utilized as much as possible to enhance UE-initiated / event-driven CSI reporting, thereby reducing overhead and / or latency. Summary of the Invention

[0004] The inventors found through research that when CSI reporting is event-triggered, how to occupy the CSI processing unit (CPU) is an issue that needs to be studied.

[0005] In response to the above problem, the present application discloses a solution. It should be noted that in the description of the present application, although the NR system and UE-initiated / event-driven CSI reporting are used as examples, the present application can also be applied to other scenarios, including but not limited to scenarios of future 6G systems, traditional CSI reporting scenarios, etc. Further, adopting a unified design solution for different scenarios (including but not limited to NR system scenarios, future 6G system scenarios, UE-initiated / event-driven CSI reporting, traditional CSI reporting, etc.) also helps to reduce hardware complexity and cost. Without conflict, the embodiments and features in the embodiments of any node in the present application can be applied to any other node.

[0209] As an example, when the triggering event is satisfied, the first signal indicates that the first CSI report is triggered; when the triggering event is not satisfied, the first signal indicates that the first CSI report is not triggered.

[0210] Typically, when the triggering event is not satisfied, the first CSI report is not sent.

[0211] As an example, how to generate the first CSI report is determined by the manufacturer of the first node itself, or is implementation-related. The following describes some typical but non-limiting implementation manners:

[0212] In one implementation manner, the first node obtains L1-RSRP based on channel measurements for a first set of timing instants, where the first set of timing instants includes at least one transmission timing of the RS resources in the first RS resource set. Generally speaking, whether L1-RSRP is filtered, or the filtering algorithm, is determined by the manufacturer of the first node itself, or is implementation-related, and can be implemented by an algorithm or in hardware.

[0213] In another embodiment, the first node obtains a plurality of L1-RSRPs based on channel measurements for the first set of timing occasions, and the plurality of L1-RSRPs respectively correspond to a plurality of RS resources in the first RS resource set. The first node selects at least one L1-RSRP from the plurality of L1-RSRPs, and the first CSI report indicates the RS resources corresponding to each L1-RSRP in the at least one L1-RSRP. There are various ways to select the at least one L1-RSRP. For example, it can be the largest one selected, it can be random, or it can be determined by the manufacturer of the first node itself, or it is implementation-related.

[0214] In another embodiment, the first node obtains a plurality of L1-RSRPs based on channel measurements for the first set of timing occasions, and the plurality of L1-RSRPs respectively correspond to a plurality of RS resources in the first RS resource set. The first node selects RS resources whose corresponding L1-RSRPs meet certain conditions from the plurality of RS resources, and the first CSI report indicates the selected RS resources.

[0215] In another embodiment, the first node obtains an RS resource channel parameter matrix H for channel measurements in the first set of timing occasions r×P ; under the condition of using a precoding matrix W P×l , the precoded channel parameter matrix is H r×P ·W P×l , where l is the number of ranks or layers. In one case, l is a positive integer not greater than P. In another case, the precoding matrix is an identity matrix, and at this time P = l. The equivalent channel capacity of H r×P ·W P×l is calculated using criteria such as SINR (Signal Interference Noise Ratio), EESM (Exponential Effective SINR Mapping), or RBIR (Received Block mean mutual Information Ratio), and then the first CSI report is obtained 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), and the first node obtains the interference through interference measurements in the first set of timing occasions. Usually, the mapping from the equivalent channel capacity to the CSI directly depends on receiver performance, or hardware-related factors such as the modulation method.

[0216] For the case where channel parameter matrices for multiple RS resources are obtained for channel measurements in the first set of timing instants, in one implementation, for each RS resource, the above method can be used to obtain the equivalent channel capacity respectively, select the RS resource corresponding to the maximum equivalent channel capacity, and indicate this RS resource in the first CSI report.

[0307] Embodiment 3 shows 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 the appendix Figure 3 as shown. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture of the control plane 300 for 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, is shown with 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 PHY301 herein. Layer 2 (L2 layer) 305 is above PHY301 and 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, and these sublayers terminate at the second communication node device.

[0315] Example 4

[0316] Example 4 exemplifies 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. 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.

[0317] 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.

[0318] 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.

[0319] 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 (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 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 spatial 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 time-domain multi-carrier symbol streams. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol streams. Each transmitter 418 converts the baseband multi-carrier symbol streams provided by the multi-antenna transmit processor 471 into radio frequency streams, and then provides them to different antennas 420.

[0320] 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 for providing 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, the controller / processor 459 provides demultiplexing between the transmission and the logical channels, 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 acknowledgment (ACK) and / or negative acknowledgment (NACK) protocols to support the HARQ operation.

[0321] 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 transmission function 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, 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.

[0322] 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 receiving 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 L1 layer functions. A controller / processor 475 implements 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 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.
