Description

A method and apparatus for channel state information reporting in wireless communication TECHNICAL FIELD

[0001] The present application relates to a method and apparatus in wireless communication system, and particularly relates to a method and apparatus for supporting channel state information reporting in wireless communication. BACKGROUND

[0002] The application scenarios of future wireless communication systems are increasingly diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, it is decided at the 72nd plenary meeting of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) RAN (Radio Access Network, Radio Access Network) to study the new radio technology (NR, New Radio) (or 5G), and the new radio technology WI (Work Item, Work Item) is passed at the 75th plenary meeting of 3GPP RAN, and the standardization work of NR begins.

[0003] Channel state information (Channel Status Information, CSI) reporting is a basic and important research direction in wireless communication. The basic principle of CSI reporting is that the base station configures the RS (Reference Signal, Reference Signal) resource for the user equipment (User Equipment, UE), the UE performs measurement on the RS and calculates the CSI, and then reports it to the base station to assist the base station to perform scheduling and beam management. In order to be able to adapt to various network scenarios and meet different requirements, 3GPP has been evolving the CSI reporting process. SUMMARY

[0004] The inventors find that the CSI reporting triggered by the UE needs further study. In view of the above problems, the present application discloses a solution. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other. Although the present application is directed to the Uu air interface, the present application is also applicable to the PC5 air interface. Further, although the original intention of the present application is directed to the CSI reporting triggered by the UE, the present application is also applicable to other reporting scenarios triggered by the UE, including but not limited to physical layer reporting and MAC (Medium Access Control) sublayer reporting, wherein the physical layer reporting includes but is not limited to UCI (Uplink Control Information) reporting and L1 (layer 1) measurement reporting; the MAC sublayer reporting includes but is not limited to BFR (Beam Failure Recovery) reporting, and achieves similar technical effects. In addition, the unified solution for different scenarios also helps to reduce hardware complexity and cost. In particular, the explanation of the terminology, nouns, functions, and variables in the present application (if not specially stated) can refer to the definitions in the specification protocols TS38 series and TS37 series of 3GPP.

FIG. 3 is a diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and control plane 300, which exhibits the radio protocol architecture for the control plane 300 of the UE and gNB in 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 the PHY 301 herein. Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the UE and gNB by means of the PHY 301. The L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, a RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which are terminated at the gNB on the network side. The PDCP sublayer 304 provides data ciphering and integrity protection, and also handles handover between gNBs. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and also provides duplicate data packet detection and protocol error detection. The MAC sublayer 302 provides mapping between logical and transport channels and multiplexing of logical channel identities. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ (Hybrid Automatic Repeat Request) operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the gNB and the UE. Although not illustrated, there can also be a V2X layer above the RRC sublayer 306 in the control plane 300 of the UE, which is responsible for generating a PC5 QoS parameter set and QoS rules according to received service data or service request, generating a PC5 QoS flow corresponding to the PC5 QoS parameter set and sending the PC5 QoS flow identification and the corresponding PC5 QoS parameter set to the AS (Access Stratum) layer for QoS processing of data packets belonging to the PC5 QoS flow identification by the AS layer; the V2X layer also includes a PC5-Signaling Protocol sublayer, which is responsible for instructing the AS layer whether each transmission is a PC5-S transmission or a V2X service data transmission.The radio protocol architecture of the user plane 350 includes layer 1 (LI layer) and layer 2 (L2 layer), which are substantially the same in the user plane 350 as the corresponding layers and sub-layers in the control plane 300 for the physical layer 351, the PDCP sub-layer 354 in the L2 layer 355, the RLC sub-layer 353 in the L2 layer 355, and the MAC sub-layer 352 in the L2 layer 355, but the PDCP sub-layer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 further includes a SDAP (Service Data Adaptation Protocol) sub-layer 356, which is responsible for the mapping between a QoS (Quality of Service) flow and a data radio bearer (DRB) to support diverse services.

[0226] Embodiment 4

[0227] Embodiment 4 illustrates a hardware module diagram of a 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 450 and a second communication device 410 that communicate with each other in an access network.

[0228] The first 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.

[0229] The second communication device 410 includes a controller / processor 475, a memory 476, a data source 477, 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.

[0230] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer packets from a core network or upper layer packets from a data source 477 are provided to a controller / processor 475. The core network and the data source 477 represent all protocol layers above the L2 layer. The controller / processor 475 implements the functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets, and signaling to the first communication device 450. Transmit processor 416 and multiple antenna transmit processor 471 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of coded bits to signal constellations 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 multiple antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding, and beamforming processing, generating one or more spatial streams. The transmit processor 416 then maps to each spatial stream to a subcarrier, multiplexes the stream with reference signals (e.g., pilot) in the time and / or frequency domain, and then performs an inverse fast Fourier transform (IFFT) to generate a time-domain multicarrier symbol stream for the physical channel. The multiple antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 into a radio frequency stream, and then provides the radio frequency stream to a different antenna 420.

[0231] In transmissions from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and provides the recovered information at baseband as a stream of symbols to a receive processor 456. The receive processor 456 and a multiple access receiver processor 458 implement various signal processing functions of the Ll layer. The multiple access receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multiple carrier symbol stream from the receivers 454. The receive processor 456 converts the baseband multiple carrier symbol stream from the receive analog precoding / beamforming operations from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed from the received signal by the receive processor 456, where the reference signals will be used for channel estimation, and the data signals are recovered after multiple access detection in the multiple access receiver processor 458 for any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered by the receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to a controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer readable medium. In transmissions from the second communication device 410 to the first communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the second communication device 410. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals can also be provided to the L3 for L3 processing.

[0232] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 provides upper layer data packets to a controller / processor 459 using the data source 467. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels, L2 layer functionality for the user plane and control plane. The controller / processor 459 is also responsible for retransmission of lost packets, and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping, channel coding processing, multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, and then transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, which are further processed by analog precoding / beamforming operations in multi-antenna transmit processor 457 and then provided to different antennas 452 via transmitters 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency signal, and then provides the radio frequency signal to the antenna 452.

[0233] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive functions at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its respective antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to multi-antenna receive processor 472 and receive processor 470. Receive processor 470 and multi-antenna receive processor 472 together implement the functionality of the L1 layer. Controller / processor 475 implements the functionality of the L2 layer. 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. In the transmission from the first communication device 450 to the second communication device 410, controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the first communication device 450. Upper layer data packets from controller / processor 475 can be provided to the core network or all protocol layers above the L2 layer, and various control signals can be provided to the core network or L3 for L3 processing.
