Description

A method and device used in a node for wireless communication

Technical Field

The present application relates to a transmission method and device in a wireless communication system, and in particular to a transmission method and device for wireless signals in a wireless communication system supporting a cellular network.

Background technique

In the NR system, Massive MIMO (Multiple Input Multiple Output) is an important technical feature. In Massive MIMO, multiple antennas form narrow beams pointing in a specific direction through beamforming to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the beams of the communicating parties need to be aligned for effective communication.

In a wireless communication system supporting multi-antenna transmission, 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 the NR system, in order for the user equipment to obtain the QCL (Quasi co-location) parameters of a reference signal resource, other reference signal resources that are quasi-co-located with it by higher-layer signaling are supported, such as CSI-RS (Channel State Information-Reference Signal) resources, SS (Synchronization Signal)/PBCH (Physical Broadcast CHannel) block resources.

Summary of the invention

The inventors have found through research that when a CSI report is generated based on a reference signal resource, the relationship between the reference signal resource quasi-co-located with the reference signal resource and the CSI report is a key issue that needs to be studied.

In view of the above problems, the present application discloses a solution. It should be noted that, although the above description uses uplink as an example, the present application is also applicable to other scenarios such as downlink and companion link (Sidelink), and obtains a similar technical effect in the uplink. In addition, different scenarios (including but not limited to uplink, downlink and companion link) adopt a unified solution to also help reduce hardware complexity and cost. In the absence of conflict, the embodiments in 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 in the present application and the features in the embodiments can be arbitrarily combined with each other.

As an embodiment, the interpretation of the terminology in the present application refers to the definition of the TS36 series of specification protocols of 3GPP.

As an example, the interpretation of the terms in the present application refers to the definitions of the TS38 series of specification protocols of 3GPP.

As an example, the interpretation of the terms in the present application refers to the definitions of the TS37 series of specification protocols of 3GPP.

As an embodiment, the interpretation of the terms in this application refers to the definition of the standard protocol of IEEE (Institute of Electrical and Electronics Engineers).

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

receiving first signaling, where the first signaling is used to determine first CSI configuration information;

generating a first CSI report according to whether at least a second reference signal resource is detected, and sending the first CSI report;

The first CSI configuration information is used to indicate a first reference signal resource set, and the first reference signal resource set and the second reference signal resource are quasi-co-located; when the second reference signal resource is detected, the first CSI report is obtained based on the measurement of the first reference signal resource set; when the second reference signal resource is not detected, the first CSI report is independent of the measurement of the first reference signal resource set.

As an embodiment, the problem to be solved by the present application includes: when a CSI report is generated based on a reference signal resource, the relationship between whether a reference signal resource quasi-co-located with the reference signal resource is detected and the CSI report.

As an embodiment, the essence of the above method is that when a CSI report is generated based on a reference signal resource, the CSI report is determined according to whether a reference signal resource quasi-co-located with the reference signal resource is detected.

As an embodiment, the advantage of adopting the above method is that whether a reference signal resource is detected reflects the corresponding beam quality to a certain extent. If it is detected, it means that the beam quality is good, while if it is not detected, it means that the beam quality is poor. When the beam quality is poor, if the CSI report is generated based on the measured channel and/or interference, the reported CSI may still be good and cannot reflect the actual situation that the beam quality is poor. The above method generates a CSI report based on the measured channel and/or interference only when the beam quality is good, thereby avoiding the above problem.

As an embodiment, the advantage of adopting the above method is that whether a reference signal resource is detected to a certain extent reflects whether the corresponding beam is available. If it is detected, it means that the beam is available, and if it is not detected, it means that the beam is unavailable. When the beam is unavailable, if a CSI report is generated based on the measured channel and/or interference, it cannot reflect the actual situation that the beam is unavailable. The above method generates a CSI report based on the measured channel and/or interference only when the beam is available, thereby avoiding the above problem.

As an embodiment, the essence of the above method is that only when the reference signal resource corresponding to the CSI report of one cell is quasi-co-located with the reference signal resource of another cell that is not a serving cell, the generation of the CSI report of the one cell is determined based on whether the reference signal resource of the other cell that is not a serving cell is detected.

According to one aspect of the present application, it is characterized in that the identifier of the cell to which the second reference signal resource is associated is different from the identifier of any serving cell of the sender of the first CSI report; only when the identifier of the cell to which the second reference signal resource is associated is different from the identifier of any serving cell of the sender of the first CSI report, the behavior is performed by the sender of the first CSI report according to whether at least the second reference signal resource is detected to generate the first CSI report.

According to one aspect of the present application, it is characterized in that the cell to which the first reference signal resource set is associated is a serving cell; in the cell to which the first reference signal resource set is associated, there is at least one TCI state associated with a cell having a different identifier from any serving cell of the sender of the first CSI report.

According to one aspect of the present application, it is characterized in that the first CSI report includes at least one CSI reporting amount; when the second reference signal resource is not detected by the sender of the first CSI report, the value of at least one CSI reporting amount in the first CSI report is default.

As an embodiment, compared with the traditional solution, this application has the following advantages:

-Whether a reference signal resource is detected to a certain extent reflects the corresponding beam quality. If it is detected, it means that the beam quality is good, while if it is not detected, it means that the beam quality is poor. When the beam quality is poor, if the CSI report is still generated based on the measured channel and/or interference according to the traditional scheme, the reported CSI may still be good and cannot reflect the actual situation that the beam quality is poor. In this application, only when the beam quality is good, the CSI report is generated based on the measured channel and/or interference, thereby avoiding the above problems.

-Whether a reference signal resource is detected to a certain extent reflects whether the corresponding beam is available. If it is detected, it means that the beam is available, and if it is not detected, it means that the beam is unavailable. When the beam is unavailable, if the CSI report is still generated based on the measured channel and/or interference according to the traditional scheme, it cannot reflect the actual situation that the beam is unavailable. In the present application, the CSI report is generated based on the measured channel and/or interference only when the beam is available, thereby avoiding the above problems.

-When the reference signal resource corresponding to the CSI report of a cell is quasi-co-located with the reference signal resource of another cell that is not a serving cell, the generation of the CSI report of the cell is determined based on whether the reference signal resource of the other cell that is not a serving cell is detected; when the reference signal resource of the other cell that is not a serving cell is not detected, the CSI report reflects the poor beam quality or the unavailability of the beam.

FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 shows the 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, using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to 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, which terminate at the second communication node device.

Example 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

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 .

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.

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.

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, where 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, 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.

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.

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 storing 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.
