METHOD AND DEVICE IN NODES USED FOR WIRELESS COMMUNICATION

BACKGROUND
Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a scheme and device related to CSI (Channel Status Information) in a wireless communication system.

Related Art

In traditional wireless communications, the UE (User Equipment) report may comprise at least one of a variety of auxiliary information, such as CSI, Beam Management related auxiliary information, positioning-related auxiliary information and so on. CSI comprises at least one of a CRI (CSI-RS Resource Indicator), an RI (Rank Indicator), a PMI (Precoding Matrix Indicator) or a CQI (Channel quality indicator).

The network equipment selects appropriate transmission parameters for the UE according to the UE's report, such as a camping cell, an MCS (Modulation and Coding Scheme), a TPMI (Transmitted Precoding Matrix Indicator), a TCI (Transmission Configuration Indication) and other parameters. In addition, UE's report can be used to optimize network parameters such as better cell coverage, switching base stations according to UE's location, etc.

In NR (New Radio) system, CSI report can be periodic, semi-persistent, or aperiodic. Semi-persistent CSI report needs to be activated through DCI (Downlink Control Information) or MAC CE (Medium Access Control layer Control Element), while aperiodic CSI report needs to be triggered through DCI.

SUMMARY

In the NR (New Radio) system, one DCI scheduling Physical Uplink Shared Channels (PUSCHs)/Physical Downlink Shared Channels (PDSCHs) for multiple cells is proposed. Inventors found through researches that the existing CSI report triggering scheme may no longer be applicable in the application scenario.

To address the above problem, the present application provides a solution. It should be noted that although the original intention of the present application is to explain the transmission scenario of one DCI scheduling PUSCHs/PDMSHs for multiple cells, the present application can also be applied to the transmission scenario of one DCI scheduling a PUSCH/PDMSH for a single cell. Furthermore, adopting a unified design scheme for different scenarios (including but not limited to one DCI scheduling PUSCHs/PDSCHs for multiple cells and one DCI scheduling a PUSCH/PDSCH for a single cell) can also help reduce hardware complexity and cost. If no conflict is incurred, embodiments in any node in the present application and the characteristics of the embodiments are also applicable to any other node, and vice versa. And the embodiments in the present application and the characteristics in the embodiments can be arbitrarily combined if there is no conflict.

In one embodiment, the first CSI set adopts a modulation method same as the PUSCH of the first cell.

Generally speaking, how to calculate CSI is determined by the hardware equipment manufacturer. The following takes CQI as an example to introduce a non-restrictive implementation:

- the first node first performs a channel measurement for a CSI-RS resource to obtain a channel parameter matrix H_r×t, where r and t are a number of receiving antennas and a number of antenna ports used for transmission, respectively; under the condition of using a precoding matrix W_t×l, a channel parameter matrix after precoding is H_r×t·W_t×l, where l is rank or a number of layers; an equivalent channel capacity of H_r×t·W_t×lis calculated using, for example, SINR, EESM (Exponential Effective SINR Mapping), or RBIR (Received Block mean mutual Information Ratio) criterion, and then, CQI is determined by the equivalent channel capacity through methods such as table lookup. In general, the calculation of the equivalent channel capacity requires the first node to estimate noise and interference. In general, a mapping between the equivalent channel capacity and a value of the CQI depends on hardware related factors such as receiver performance or modulation mode. The precoding matrix W_t×tis usually fed back by the first node through RI or PMI.

Compared with CQI, L1-SINR does not carry information of the receiver, so the calculation of the equivalent channel capacity above is omitted.

FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a first communication node (UE, gNB or an RSU in V2X) and a second communication node (gNB, UE or an RSU in V2X), or between two UEs is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present application. The layer 2 (L2) 305 is above the PHY 301, and is in charge of a link between a first communication node and a second communication node, or between two UEs. L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304.

Embodiment 4

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

The first communication device 410 comprises 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.

The second communication device 450 comprises 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.

In a transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, a higher layer packet from the core network is provided to a controller/processor 475. The controller/processor 475 provides a function of the L2 layer. In DL transmission, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation for the second communication device 450 based on various priorities. The controller/processor 475 is also in charge of HARQ operation, retransmission of a lost packet, and a signaling to the second communication node 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (that is, PHY). The transmitting processor 416 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the second communication device 450, and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more parallel streams. The transmitting processor 416 then maps each parallel stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multi-carrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas 420.

In a 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 via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver 454. The receiving processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any second communication device 450-targeted parallel stream. Symbols on each parallel stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the first communication node 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 functions of the L2 layer. The controller/processor 459 can be connected to a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In downlink (DL) transmission, the controller/processor 459 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing. The controller/processor 459 also performs error detection using ACK and/or NACK protocols as a way to support HARQ operation.

In a transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the first communication device 410 described in DL transmission, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the first communication device 410 so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operation, retransmission of a lost packet, and a signaling to the first communication device 410. The transmitting processor 468 performs modulation mapping and channel coding. The multi-antenna transmitting processor 457 implements digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, as well as beamforming. Following that, the generated parallel streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor 468, and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457 and provided from the transmitters 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In the transmission from the second communication device 450 to the first communication device 410, the function of the first communication device 410 is similar to the receiving function of 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 via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and multi-antenna receiving processor 472 collectively provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be connected with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the second communication device 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network. The controller/processor 475 can also perform error detection using ACK and/or NACK protocols to support HARQ operation.
