Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a CSI (Channel State Information) measurement scheme and device in a wireless communication system. Background Art

[0002] In wireless communication systems supporting MIMO (Multiple-Input Multiple-Output), it is a common technology for UE (User Equipment) to generate and feedback CSI (Channel Status Information) based on channel and / or interference measurement to assist the base station in multi-antenna processing. In 5G (the 5th generation) NR (new radio) systems, in order for 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 for interference measurement can also be configured. 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, and the UE sends CSI reporting on the time-frequency resources configured or indicated by the base station.

[0003] In order to solve the coverage problem and achieve greater spectrum efficiency, the 3GPP (3rd Generation Partnership Project) RAN#94 meeting passed the "NR MIMO Phase 5" work item (WI). Among them, in order to reduce the overhead and / or CSI delay of CSI reporting, the design of UE-initiated / event-driven CSI measurement and reporting is a key issue to be solved. Summary of the invention

[0004] In existing systems, the reporting types of CSI reporting include periodic reporting, semipersistent reporting and aperiodic reporting. The priority value of a CSI reporting is linearly related to the reporting type. If a new reporting type is supported, how to calculate its priority value needs to be studied.

[0005] In view of 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 the transmission direction, or base stations or user equipment with stronger capabilities, such as supporting the same frequency full-duplex scenario, or for different application scenarios, such as mobile broadband, ultra-reliable low-latency communication, large-scale machine communication, non-terrestrial network, synaesthesia integrated network, intelligent super surface, 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, intelligent super surface, terahertz network scenarios) also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments of any node of 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.

[0006] The present application discloses a method in a first node used for wireless communication, characterized by comprising:

[0007] Receiving a first information block; wherein the first information block configures a CSI report;

[0008] Among them, the priority value of the CSI report configured by the first information block is linearly related to the first parameter, and the value range of the first parameter includes M candidate values, M is a positive integer greater than 1; the M candidate values ​​are respectively the values ​​of the first parameter under M reporting types; when the reporting type of the CSI report configured by the first information block is one of the M reporting types, the value of the first parameter is a candidate value among the M candidate values ​​corresponding to the reporting type of the CSI report configured by the first information block; when the reporting type of the CSI report configured by the first information block does not belong to the M reporting types, the value of the first parameter is the same as a candidate value of the corresponding reference reporting type among the M candidate values, and the reference reporting type is one of the M reporting types.

[0009] As an embodiment, the problem to be solved by the present application includes: how to determine the priority value according to the reporting type of the CSI report.

[0010] As an embodiment, the essence of the above method is that the priority value of a CSI report is related to a first parameter, M reporting types correspond to M candidate values ​​of the first parameter respectively, and for a reporting type other than the M reporting types, one of the M candidate values ​​is reused.

[0011] 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.

[0012] As an embodiment, the advantage of adopting the above method is that it has good backward compatibility;

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

[0014] As an embodiment, the advantage of adopting the above method is that it is unnecessary to add new candidate values.

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

[0016] According to one aspect of the present application, it is characterized in that M is equal to 4, and the M candidate values ​​are 0, 1, 2 and 3 respectively; the M reporting types include non-periodic reporting carried on PUSCH, semi-persistent reporting carried on PUSCH, semi-persistent reporting carried on PUCCH and periodic reporting carried on PUCCH.

[0017] According to one aspect of the present application, it is characterized in that M is equal to 4, and the M candidate values ​​are 0, 1, 2 and 3 respectively; the M reporting types include non-periodic reporting carried on PUSCH, semi-persistent reporting carried on PUSCH, semi-persistent reporting carried on PUCCH and periodic reporting carried on PUCCH; the reporting type that does not belong to the M reporting types includes event-triggered reporting.

[0019] According to one aspect of the present application, it is characterized in that the reference reporting type is a reporting type corresponding to the minimum value of the M candidate values; or, the reference reporting type is a non-periodic reporting carried on PUSCH.

[0020] As an embodiment, the advantage of adopting the above method is that, for a reporting type that does not belong to the M reporting types, its priority value is determined according to the minimum value among the M candidate values, and the smaller the priority value, the higher the priority, which is equivalent to that under this reporting type, the value of the first parameter follows the reporting type with the highest priority among the M reporting types. The advantage of adopting the above method is that the CSI of this reporting type can be prioritized in resource allocation, CSI processing unit allocation, resource conflict, etc., and can be reported more reliably and quickly.

[0021] As an embodiment, the essence of the above method is that those skilled in the art know that the non-periodic reporting carried on PUSCH is the reporting type with the highest priority among all reporting types supported by the current standard; for a reporting type that does not belong to the M reporting types, the value of the first parameter follows the non-periodic reporting carried on PUSCH, giving the reporting type a higher priority. The advantage of adopting the above method is that the CSI of this reporting type can be given priority in resource allocation, CSI processing unit allocation, resource conflict, etc., and can be reported more reliably and quickly.

[0022] According to one aspect of the present application, it is characterized in that the reference reporting type is a reporting type corresponding to the maximum value of the M candidate values; or, the reference reporting type is a periodic report carried on PUCCH.

[0023] As an embodiment, the essence of adopting the above method is that, for a reporting type that does not belong to the M reporting types, its priority value is determined according to the maximum value of the M candidate values, and the smaller the priority value, the higher the priority, which is equivalent to that under this reporting type, the value of the first parameter follows the reporting type with the lowest priority among the M reporting types. The advantage of adopting the above method is that, in the case of resource allocation, CSI processing unit allocation, resource conflict, etc., a reporting type other than the M reporting types can allow other reporting types to be prioritized, thereby minimizing the impact on the priorities of the M reporting types as much as possible.

[0024] As an embodiment, the essence of adopting the above method is that those skilled in the art know that the periodic reporting carried on PUCCH is the reporting type with the lowest priority among all reporting types supported by the current standard; for a reporting type that does not belong to the M reporting types, the value of the first parameter follows the periodic reporting carried on PUCCH. The advantage of adopting the above method is that a reporting type other than the M reporting types can give priority to other reporting types in resource allocation, CSI processing unit allocation, resource conflict, etc., so as to minimize the impact on the priority of the M reporting types.

[0025] According to one aspect of the present application, it is characterized in that the reference reporting type is a semi-persistent reporting carried on PUSCH; or, the reference reporting type is a semi-persistent reporting carried on PUCCH.

[0026] As an embodiment, the advantage of adopting the above method is that, for a reporting type that does not belong to the M reporting types, the value of the first parameter follows the semi-persistent reporting carried on the PUSCH or the semi-persistent reporting carried on the PUCCH. The advantage of adopting the above method is that in the case of resource allocation, CSI processing unit allocation, resource conflict, etc., the requirements of reliability and delay are taken into account, and the impact on the priority of the M reporting types is also considered.

[0027] According to one aspect of the present application, it is characterized in that when the reporting type of the CSI report configured by the first information block does not belong to the M reporting types, the reference reporting type is which reporting type among the M reporting types depends on the reporting amount of the CSI report configured by the first information block.

[0028] As an embodiment, the advantage of adopting the above method is that, for a reporting type that does not belong to the M reporting types, the value of the first parameter follows which reporting type among the M reporting types is related to the reporting amount. The advantage of adopting the above method is that different reporting amounts can have different priorities.

[0029] According to one aspect of the present application, it is characterized in that when the reporting type of the CSI report configured by the first information block is an event triggered report, the reference reporting type is which reporting type among the M reporting types depends on the triggering event used to trigger the CSI report configured by the first information block; the event triggered report is a reporting type other than the M reporting types.

[0030] As an embodiment, the advantage of adopting the above method is that, for event-triggered reporting, the value of the first parameter follows which reporting type among the M reporting types is related to the triggering event. The advantage of adopting the above method is that CSI reporting under different triggering events can have different priorities.

[0031] As an embodiment, the advantage of adopting the above method is that the candidate value of the first parameter is not increased, and event-triggered CSI reporting is supported.

[0032] 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 reporting is sent only when the triggering event is satisfied also simplifies the design and makes little change to the standard.

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 3The radio protocol architecture of 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 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. The L1 layer will be referred to as PHY301 in this article. 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, which terminate at the second communication node device.

[0154] Example 4

[0155] 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 the attached figure. Figure 4 Attached 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.

[0156] The first communication 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 .

[0157] 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.

[0158] In 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 allocation of radio resources 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, 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), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing 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 a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation 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 a different antenna 420.

[0159] 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 RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any parallel stream destined for the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving 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 storing program codes and data. The memory 460 may be referred to as a computer-readable medium. In DL (DownLink, downlink), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the 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 L3 for L3 processing. The controller / processor 459 is also responsible for error detection using confirmation (ACK) and / or negative confirmation (NACK) protocols to support HARQ operations.

[0160] 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 function at the first communication device 410 described in 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. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. 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.

[0161] 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 reception 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 a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 that stores program codes and data. The memory 476 can be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transmission and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 can 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.
