Description

A method and device used in a node for wireless communication Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a method and apparatus for transmitting wireless signals in a wireless communication system supporting a cellular network. Background Art

[0002] In 2020, the industry first proposed the 5.5G industry vision for 5G evolution. In April 2021, the 3rd Generation Partner Project (3GPP) officially designated 5G-Advanced as the 5.5G evolution of 5G, initiating the standardization process. The 5G-Advanced technical specifications are planned to be defined in three releases: Rel-18 (Release-18), Rel-19, and Rel-20. By the end of 2021, the first 28 projects under Rel-18 were approved, marking the substantive stage of 5.5G technology research and standardization. Future Rel-19 and Rel-20 releases will further explore new 5G-Advanced services and architectures.

[0003] The Reconfigurable Intelligent Surface (RIS) is an artificial electromagnetic surface structure with programmable electromagnetic properties, consisting of 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, and polarization, 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 shaping gain achieved with a larger antenna scale. It is regarded as a key technology for 5G-Advanced research and one of the core visions of 6G.

[0004] Summary of the Invention

[0005] Currently, 3GPP Release 18 has established a project for Network Controlled Repeaters (NCRs), which are controlled by the network to perform amplification and directional forwarding. NCRs have the transceiver functionality of mobile terminals (MTs), receiving control signaling sent by base stations to the NCRs via control links. The backhaul link and access link utilize separate radio frequencies, while the control and backhaul links share a common radio frequency to reduce cost and complexity.

[0006] As the predecessor of RIS, the basic mechanism and structure of Rel-18NCR can serve as a foundation for RIS research. However, because RIS only redirects signals without performing frequency conversion, the backhaul link and access link of RIS need to share a common frequency band. The control link can use an independent radio or share a radio module with the signal reflector to provide more design flexibility and optimize RIS performance. However, the shared radio frequency control link will interfere with the downlink signal from the base station. The separate radio frequency control link may also be subject to power limitation in full-duplex mode due to the passive nature of RIS. Therefore, the duplex mode of the control link and access link in RIS scenarios is an issue that needs to be addressed.

[0007] In response to the above problems, the present application discloses a solution. It should be noted that, in the description of the above problem, the NR (New Radio) system is used as an example. The present application is also applicable to scenarios such as the future 6G system, achieving technical effects similar to the NR system. Furthermore, although the original intention of the present application is for RIS scenarios, the present application can also be applied to other non-RIS scenarios. Furthermore, adopting a unified design solution 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), URLLC (Ultra Reliable Low Latency Communication) networks, vehicle networks, etc.) can also help reduce hardware complexity and cost.

[0350] Example 3

[0351] 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 FIG3 .

[0352] FIG3 is a schematic diagram illustrating an embodiment of a wireless protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the wireless protocol architecture for a first communication node device (a UE or RSU (Road Side Unit) in a V2X (Vehicle to Everything) network, a vehicle-mounted device, or a vehicle-mounted communication module) and a second node device (a gNB, a UE or RSU in a V2X network, a vehicle-mounted device, or a vehicle-mounted communication module), or the control plane 300 between two UEs using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (PHYsical layer) signal processing functions. L1 will be referred to herein as PHY 301. L2 305 is above PHY 301 and is responsible for the link between the first and second node devices, 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 support for inter-zone mobility of the first communication node device between the second communication node devices. 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 radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). 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 355, the RLC sublayer 353 in L2 355, and the MAC sublayer 352 in L2 355. However, the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead. L2 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping QoS (Quality of Service) flows and Data Radio Bearers (DRBs) to support service diversity. Although not shown in the figure, the first communication node device may have several upper layers above L2355, including a network layer (e.g., IP (Internet Protocol) layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0353] As an embodiment, the wireless protocol architecture in FIG3 is applicable to the first node in this application.

[0361] Example 4

[0362] 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 FIG4. FIG4 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.

[0363] The first communications 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 .

[0364] 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 .

[0365] The third communication device 490 includes a control component 491 , an information component 496 , a memory 495 , and a reflective surface 492 .

[0366] In transmission from the first communications device 410 to the second communications device 450, at the first communications device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 functionality. 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 communications 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 communications device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 (i.e., physical layer). The transmit processor 416 performs coding and interleaving to facilitate forward error correction (FEC) at the second communications 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-ary phase shift keying (M-PSK), and 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 and non-codebook-based precoding and beamforming, 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., a pilot) in the time and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations 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, which is then provided to a different antenna 420.

[0367] During 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 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, which is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various L1 signal processing functions. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream after 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 signal and reference signal are demultiplexed by the receive processor 456, where the reference signal is used for channel estimation. The data signal is recovered in the multi-antenna receive processor 458 after multi-antenna detection to any parallel stream destined for the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. The receive 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 L2 functionality. 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, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover 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 acknowledgment (ACK) and / or negative acknowledgment (NACK) protocols to support HARQ operations.

[0368] During transmission from the second communications device 450 to the first communications device 410, at the second communications 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 transmit functionality at the first communications device 410 described in the 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 communications device 410, implementing L2 functionality for both 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 communications device 410. The transmit processor 468 performs modulation mapping and channel coding, while the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming. The transmit processor 468 then modulates the resulting parallel streams into multi-carrier / single-carrier symbol streams. After analog precoding and beamforming operations in the multi-antenna transmit processor 457, these streams are provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a RF symbol stream before providing it to the antenna 452.

[0369] During transmission from the second communication device 450 to the first communication device 410, the functionality at the first communication device 410 is similar to the reception functionality at the second communication device 450 described for transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives RF signals via its corresponding antenna 420, converts the received RF signals into baseband signals, and provides the baseband signals to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement L1 functionality. The controller / processor 475 implements L2 functionality. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transmit and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 may 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.

[0370] The third communication device 490 can be controlled by the first communication device 410 and / or the second communication device 450 to change 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 for the third communication device 490. At least one of the transmit processor 416, receive processor 470, and controller / processor 475 of the first communication device 410 can be configured to perform various aspects in conjunction with the information component 496 or controller component 491 of the third communication device 490, or at least one of the transmit processor 468, receive processor 456, and controller / processor 459 of the second communication device 450 can be configured to perform various aspects in conjunction with the information component 496 or controller component 491 of the third communication device 490.

[0371] 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. Information about the third communication device 490 may be known to the network based on network planning, and the base station may provide the location of the third communication device 490 and other information about the third communication device 490 to other nodes (e.g., terminals in a cellular cell). For example, the base station may transmit the information about the third communication device 490 in system information. Each terminal within the coverage area of ​​the cellular cell may receive the system information to discover the existence, location, capabilities, or other information about the third communication device 490.

[0372] During transmission when the first communication device 410 and / or the second communication device 450 communicates using the third communication device 490, a plurality of resonant elements form a reflection surface 492 at the third communication device 490 to receive a downlink signal from the first communication device 410 or an uplink signal from the second communication device 450. Each resonant element can adjust (e.g., apply a phase shift to directionally reflect the received signal) the corresponding received signal. The control component 491 can configure phase or amplitude changes by applying precoding weights to each resonant element, so that the third communication device 490 can reradiate the output beam in different directions given a specific input beam.

[0373] In some cases, when the third communication device 490 operates passively to merely reflect or refract a beam from a transmitter to a receiver, the third communication device 490 can function as a nearly passive device, operating without significant power consumption. In some cases, the direction of reflection or refraction can be controlled by a control node or network controller.

[0374] In the transmission from the control node and the third communication device 490, in the DL, at the third communication device 490, the information component 496 can 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 the 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.
