Description

Technical Field

[0001] 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 Art

[0002] In 2020, the 5.5G industry vision of 5G evolution was first proposed by the industry. In April 2021, 3GPP (3rd Generation Partner Project) officially named 5G evolution 5.5G as 5G-Advanced, started the standardization process, and planned to define 5G-Advanced technical specifications through three versions: Rel-18 (Release-18), Rel-19 and Rel-20. At the end of 2021, the first batch of 28 projects of Rel-18 were approved, and 5.5G technology research and standardization entered the substantive stage. The future Rel-19 and Rel-20 will further explore new 5G-Advanced services and architectures.

[0003] In 5G-Advanced and the future 6G, more advanced technologies will be adopted to improve the performance of wireless communication systems and meet the needs of more application scenarios. Typical technologies include but are not limited to AI (Artificial Intelligence) or ML (Machine Learning), full-duplex mode or sub-band non-overlapping full-duplex (SBFD), and reconfigurable intelligent metasurface (RIS). AI / ML aims to use advanced artificial intelligence and machine learning technologies to greatly improve the performance of wireless communications, including CSI (Channel State Information) feedback accuracy / overhead, channel estimation, channel prediction, positioning, etc. Full-duplex mode or sub-band non-overlapping full-duplex technology greatly improves resource utilization and reduces latency by supporting base station equipment to perform uplink and downlink transmission simultaneously. Reconfigurable intelligent metasurface is an artificial electromagnetic surface structure with programmable electromagnetic properties, which contains a large number of independent low-cost passive subwavelength resonant units. Each RIS unit has independent electromagnetic wave control capabilities, and can control the response of each unit to wireless signals, such as phase, amplitude, polarization, etc., by changing the parameters and spatial distribution of the RIS unit. By superimposing the wireless response signals of a large number of RIS units, specific beam propagation characteristics are formed on a macro level, thereby forming a flexible and controllable shaped beam, which can eliminate coverage blind spots, enhance edge coverage, and increase the rank of multi-stream transmission. These technologies have great potential to improve the overall performance of future wireless systems and are regarded as key technologies for 5G-Advanced research and the core vision of 6G. The adoption of these technologies will not only bring performance improvements, but will also make the future wireless environment more complex, and existing designs will need to be enhanced to adapt to future application environments.

[0004] Beam-based communication is a key technology in the 5G NR (New Radio) system, and the introduction of the TCI (Transmission Configuration Indicator) state provides feasibility for beam-based communication, for example, assisting the UE (User Equipment) to determine beam-related parameters for receiving and / or transmitting. In 5G-Advanced and future 6G, in order to better serve the new technologies to bring more and more diverse wireless environments and application scenarios, the design, configuration and application of the TCI state need to be enhanced. Summary of the invention

[0005] The inventors have found through research that in scenarios where 5G-Advanced and future 6G advanced technologies are used, the transmission characteristics of the wireless channel will have new features, and the communication equipment will also have new features in acquiring channel characteristics. In the NR system, the introduction of the TCI state is closely related to the transmission characteristics of the wireless channel. How to enhance the technical architecture based on the TCI state in new application scenarios and transmission environments is a problem that needs to be solved.

[0006] In view of the above problems, the present application discloses a solution. It should be noted that in the description of the present application, AL / ML, full-duplex / SBFD and RIS scenarios, as well as beam-based communication are only used as a typical application scenario or example, and the present application can also be applied to other scenarios; further, the use of a unified design scheme for different scenarios (such as other scenarios, including but not limited to non-beam communication, capacity enhancement system, short-range communication system, unlicensed spectrum communication, IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) network, Internet of Vehicles, etc.) can also help reduce hardware complexity and cost.

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.

[0478] Example 4

[0479] 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.

[0480] 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 .

[0481] 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.

[0482] 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 on the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing to generate one or more parallel 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 different antennas 420.

[0483] 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.

[0484] 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.

[0485] 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.
