Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a method and device for transmitting 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] Reconfigurable Intelligent Surface (RIS) 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 the response of each unit to wireless signals, such as phase, amplitude, polarization, etc., can be controlled 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 scale, thereby forming a flexible and controllable shaped beam, achieving the effect of eliminating coverage blind spots, enhancing edge coverage, and increasing the rank of multi-stream transmission. RIS technology has the characteristics of low cost, low energy consumption, programmability, easy deployment, and high shaped gain with a larger antenna scale. It is regarded as a key technology for 5G-Advanced stage research and one of the core visions of 6G. Summary of the invention

[0004] Currently, 3GPP Rel-18 has established a project for Network Controlled Repeater (NCR), which controls NCR through the network to amplify and directional forwarding. NCR has the transceiver function of a mobile terminal (MT), and can receive control signaling sent by the base station to NCR through a control link. The backhaul link and access link have separate radio frequencies, while the control link and backhaul link share the same radio frequency to reduce cost and complexity.

[0005] As the predecessor of RIS, the basic mechanism and structure of Rel-18 NCR can serve as the research basis of RIS. However, since RIS only changes the signal direction without performing frequency conversion processing, the backhaul link and access link of RIS need to share the frequency band. The control link can use an independent RF or share the RF module with the signal reflector to provide more design flexibility and optimize RIS performance. However, the control link with the same RF will interfere with the downlink signal from the base station. The control link with separate RF may also have the problem of full-duplex mode power limitation due to the passive characteristics of RIS. Therefore, the duplex mode of the control link and access link in the RIS scenario is an issue 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 above problems, the NR (New Radio) system is used as an example, and the present application is also applicable to scenarios such as the future 6G system, and obtains technical effects similar to the NR system; further, although the original intention of the present application is for RIS scenarios, the present application can also be applied to other non-RIS scenarios; further, the use of a unified design scheme for different scenarios (such as other non-RIS scenarios, including but not limited to NCR systems, capacity enhancement systems, short-range communication systems, NTN (Non-Terrestrial Network, non-terrestrial communication), IoT (Internet of Things, Internet of Things), URLLC (Ultra Reliable Low Latency Communication, ultra-robust low-latency communication) network, Internet of Vehicles, etc.) also helps to reduce hardware complexity and cost.

[0349] Example 3

[0350] Embodiment 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to an embodiment of the present application, as shown in the attached figure. Figure 3 shown.

[0351] Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The wireless protocol architecture of the control plane 300 for a first communication node device (RSU (Road Side Unit) in UE or V2X (Vehicle to Everything), vehicle-mounted device or vehicle-mounted communication module) and a second node device (gNB, RSU in UE or V2X, vehicle-mounted device or vehicle-mounted communication module), or between two UEs is presented in three layers: Layer 1 (Layer 1, L1), Layer 2 (Layer 2, L2) and Layer 3 (Layer 3, L3). L1 is the lowest layer and implements various PHY (PHYsical layer) signal processing functions. L1 will be referred to as PHY 301 in this article. L2 305 is above PHY 301 and is responsible for the link between the first node device and the second node device, or between two UEs through PHY 301. L2305 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 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 provides inter-zone mobility support for the first communication node device between the second communication node device. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception caused by HARQ (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 in the control plane 300 is responsible for obtaining radio resources (ie, radio bearers) and configuring lower layers using RRC signaling between the second communication node device and the first communication node device.The wireless protocol architecture of the user plane 350 includes layer 1 (L1) and layer 2 (L2). The wireless protocol architecture for the first communication node device and the second communication node device 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 L2355, the RLC sublayer 353 in L2355, and the MAC sublayer 352 in L2355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce wireless transmission overhead. L2355 in the user plane 350 also includes a SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS (Quality of Service) flows and data radio bearers (DRBs) to support the diversity of services.

[0360] Example 4

[0361] Embodiment 4 illustrates a schematic diagram of a first communication device, a second communication device, and a third 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, a second communication device 450, and a third communication device 490 communicating with each other in an access network.

[0362] 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 .

[0363] 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.

[0364] The third communication device 490 includes a control component 491 , an information component 496 , a memory 495 , and a reflective surface 492 .

[0365] 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 L2. In DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation 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 L1 (i.e., 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 mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 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 streams. The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., 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.

[0366] 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 L1. 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 with the second communication device 450 as the destination. 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 L2. 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 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 L2. Various control signals may also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using confirmation (ACKnowledgement, ACK) and / or negative confirmation (NegativeACKnowledgement, NACK) protocols to support HARQ operations.

[0367] 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 L2. 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 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.

[0368] 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 L1. The controller / processor 475 implements the L2 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. The controller / processor 475 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0369] The third communication device 490 can be controlled by the first communication device 410 and\or the second communication device 450 to change the channel implementation in a controlled manner, improve channel diversity, and provide robustness to channel blocking / fading. The first communication device 410 or the second communication device 450 can be referred to as a control node of the third communication device 490. At least one of the transmit processor 416, the receive processor 470, and the controller / processor 475 of the first communication device 410 can be configured to perform various aspects combined with the information component 496 or the controller component 491 of the third communication device 490, or at least one of the transmit processor 468, the receive processor 456, and the controller / processor 459 of the second communication device 450 can be configured to perform various aspects combined with the information component 496 or the controller component 491 of the third communication device 490.

[0370] The first communication device 410 and / or the second communication device 450 use the third communication device 490 to perform communication, sensing and / or positioning functions. The information of the third communication device 490 may be known by the network based on network planning, and the base station may provide the location of the third communication device 490 and other information of the third communication device 490 to other nodes (e.g., terminals in a cellular cell). For example, the base station may transmit the information of the third communication device 490 in system information. Each terminal in the coverage of the cellular cell may receive the system information in order to discover the existence, location, capability, or other information about the third communication device 490 of the third communication device 490.

[0371] In the transmission in which the first communication device 410 and / or the second communication device 450 uses the third communication device 490 for communication, at the third communication device 490, a plurality of resonance units form a reflection surface 492, and a downlink signal is received from the first communication device 410, or an uplink signal is received from the second communication device 450, and each resonance unit can adjust (for example, apply a phase shift to directionally reflect the received signal) the corresponding received signal. The control component 491 can configure the phase or amplitude change by applying a precoding weight to each resonance unit so that the third communication device 490 can re-radiate the output beam in different directions given a specific input beam.

[0372] In some cases, when the third communication device 490 operates passively to only reflect or refract the beam from the transmitter to the receiver, the third communication device 490 can be used as a nearly passive device, operating without a large amount of power consumption. In some cases, the reflection or refraction direction can be controlled by a control node or network controller.

[0373] In transmission from the control node and the third communication device 490, in DL, at the third communication device 490, the information component 496 may receive a signal from the control node and further process the received signal (e.g., digitize the received signal) and provide the processed signal to the control component 491. In UL, at the third communication device 490, in response to information from the control node or the third communication device data update, information / data from the control component 491 is sent or provided to the control node via the information component 496.
