Description

Technical Field

[0001] This application relates to a transmission method and a transmission device in a wireless communication system, and particularly to a transmission method and a transmission device for wireless signals in a wireless communication system supporting a cellular network.

Background Art

[0002] In conventional wireless communication, a UE (User Equipment) report may include at least one of various auxiliary information such as CSI (Channel State Information), auxiliary information related to beam management, and auxiliary information related to positioning. The CSI may include at least one of CRI (CSI-RS Resource Indicator), RI (Rank Indicator), PMI (Precoding Matrix Indicator), or CQI (Channel Quality Indicator). The network device selects appropriate transmission parameters for the UE according to the UE report such as the resident cell, MCS (Modulation and Coding Scheme), TPMI (Transmitted Precoding Matrix Indicator), and TCI (Transmission Configuration Indicator). Further, the UE report may be used to optimize network parameters such as better cell coverage and switch the base station on or off according to the position of the UE. As the number of antennas increases, the conventional PMI feedback method brings a large amount of redundant overhead. Therefore, in NR R (Release) 18, CSI compression based on AI (Artificial Intelligence) or ML (Machine Learning) was started.

Figure 3 is a schematic diagram illustrating one embodiment of the wireless protocol architecture for the user plane 350 and the control plane 300. Figure 3 illustrates the wireless protocol architecture of the control plane 300 used 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. Here, the L1 layer is referred to as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 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 the MAC (Media Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and supports handover to the first communication node device between the second communication node devices. The RLC sublayer 303 compensates for out-of-order reception due to HARQ by providing splitting and reconstructing upper-layer data packets, retransmitting lost data packets, and reordering data packets. The MAC sublayer 302 provides multiplexing between logical channels and transmit channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a single cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operation.The RRC (Radio Resource Control) sublayer 306 at Layer 3 (L3 layer) in the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers to use RRC signaling between the second and first communication node devices. The radio protocol architecture of the user plane 350 comprises Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in L2 layer 355, the RLC sublayer 353 in L2 layer 355, and the MAC sublayer 352 in L2 layer 355, except that the PDCP sublayer 354 also provides header compression for upper-layer data packets to reduce radio transmission overhead. The L2 layer 355 within the user plane 350 also includes an SDAP (Service Data Adaptive Protocol) sublayer 356, which is responsible for mapping QoS flows between data radio bearers (DRBs) and supports service diversity. Although not shown in the diagram, the first communication node device may have several higher layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the network-side P-GW and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

The multi-antenna transmitter processor 471 generates one or more parallel streams by performing digital space precoding, including codebook-based and non-codebook-based precoding, as well as beamforming on the coded and modulated symbols. The transmitter processor 416 then maps each parallel stream to subcarriers, multiplexes them with a reference signal (e.g., pilot) in the time domain and / or frequency domain, and then uses the Fast Fourier Inverse Transform (IFFT) to generate a physical channel that carries the time-domain multicarrier symbol stream. The multi-antenna transmitter processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitting device 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency stream, which is then provided to different antennas 420.

[0287] In transmission from the first communication device 410 to the second communication device 450, each receiving device 454 in the second communication device 450 receives the signal via its corresponding antenna 452. Each receiving device 454 reconstructs the information modulated on the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream provided 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 receive analog precoding / beamforming operation on the baseband multicarrier symbol stream from the receiving device 454. The receiving processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream used for the analog precoding / beamforming receive operation from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receiving processor 456. The reference signal is used for channel estimation, and the data signal is reconstructed into arbitrary parallel streams destined for the second communication device 450 via multi-antenna detection in the multi-antenna receiving processor 458. Symbols on each parallel stream are demodulated and reconstructed in the receiving processor 456 to generate a soft decision. The receiving processor 456 then decodes and deinterleaves the soft decision to reconstruct the upper layer data and control signals transmitted over the physical channel by the first communication device 410. The upper layer data and control signals are then 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 (Downlink) phase, the controller / processor 459 provides demultiplexing between the transmit channel and logical channel, packet reassembly, decoding, header decompression, and control signal processing to recover upper-layer data packets from the core network.Next, the upper-layer data packets are 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 acknowledgment (ACK) and / or negation acknowledgment (NACK) protocols to support HARQ operation.

[0288] In transmission from the second communication device 450 to the first communication device 410, the upper layer data packet is transmitted in the second communication device 450 using data source 467. The data source 467 is provided to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions in the first communication device 410 described in DL, the controller / processor 459 implements header compression, encryption, packet splitting and reordering, as well as multiplexing between logical channels and transmit channels, based on the radio resource allocation of the first communication device 410, and implements L2 layer functions of the user plane and control plane. The controller / processor 459 is also responsible for HARQ operation, 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 and non-codebook-based precoding, as well as beamforming processing. Next, the transmitting processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream, which, after undergoing analog precoding / beamforming operations in the multi-antenna transmitting processor 457, is provided to different antennas 452 via the transmitting device 454. Each transmitting device 454 first converts the baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, which is then provided to a different antenna 452.

[0289] In transmission from the second communication device 450 to the first communication device 410, the functions of the first communication device 410 are the same as the receiving functions of the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiving device 418 receives a radio frequency signal via its 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 the multi-antenna receiving processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 performs the functions of the L2 layer. 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 computer-readable media. The controller / processor 475 reconstructs upper-layer data packets from the second communication device 450 by providing multiplexing between the transmit channel and logical channel, packet reassembly, decoding, header decompression, and control signal processing. The upper-layer data packets from the controller / processor 475 can then be provided to the core network. The controller / processor 475 is also responsible for error detection using the ACK and / or NACK protocols to support HARQ operation.
