[0002] In 2020, the industrial vision of 5.5G evolution of 5G was first proposed by the industry. In April 2021, 3GPP (3rd Generation Partner Project) officially determined the name of 5.5G evolution of 5G as 5G-Advanced (5G evolution), started the standardization process, and planned to define the 5G-Advanced technical specifications through three versions of Rel-18 (Release-18, version 18), Rel-19, and Rel-20. By the end of 2021, the first 28 topics of Rel-18 were approved for research, and the research and standardization of 5.5G technology entered a substantive stage. Future Rel-19 and Rel-20 will further explore new 5G-Advanced services and architectures. In 5G-Advanced and future 6G, it is expected that more advanced technologies will be adopted to improve all aspects of the performance of wireless communication systems and meet the requirements of more application scenarios.

[0003] A reconfigurable intelligent surface (RIS) is an artificial electromagnetic surface structure with programmable electromagnetic characteristics, which includes a large number of independent low-cost passive sub-wavelength resonant units. Each RIS unit has an independent electromagnetic wave regulation ability, and can control the response of each unit to wireless signals, such as phase, amplitude, polarization, etc., by changing the parameters, spatial distribution, etc. of the RIS unit. Through the mutual superposition of the wireless response signals of a large number of RIS units, a specific beam propagation characteristic is formed macroscopically, so as to form a flexible and controllable shaped beam, achieving the effects of eliminating coverage blind spots, enhancing edge coverage, and increasing the rank of multi-stream transmission. The RIS technology has the characteristics of low cost, low power consumption, programmable, easy to deploy, and obtaining high shaping gain with a larger antenna scale, and is regarded as one of the key technologies in the research of the 5G-Advanced stage and the core vision of 6G.

[0593] Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to an embodiment of the present application, as shown in the appendix Figure 3 as follows.

[0594] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3The radio protocol architecture of the control plane 300 for 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, is shown with 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. Layer 1 will be referred to as PHY301 herein. 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. 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, and these sublayers 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 provides handover support for 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 disordered reception due to HARQ. 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 Layer 3 (L3 layer) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second communication node device and the first communication node device.

Although not shown, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP 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.).

[0606] Example 4

[0607] Example 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 4 figure. The attached Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0608] The first communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0609] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0610] In the 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 (DownLink), 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 the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and 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 space precoding on the encoded 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 subcarriers, multiplexes the modulated symbols with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol streams. Each transmitter 418 converts the baseband multi-carrier symbol streams provided by the multi-antenna transmit processor 471 into radio frequency streams and then provides them to different antennas 420.

[0611] 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 signals through its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream for providing to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations 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 receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any parallel streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each parallel stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are 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, the controller / processor 459 provides demultiplexing between the transmission and the logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing. The controller / processor 459 is also responsible for error detection using the acknowledgment (ACK) and / or negative acknowledgment (NACK) protocols to support HARQ operations.

[0612] 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 an upper layer data packet to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit 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 the 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. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated parallel streams into multi-carrier / single-carrier symbol streams, and after passing through analog precoding / beamforming operations in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. 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.

[0613] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receive functions 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 a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the L1 layer functions. A controller / processor 475 implements the L2 layer functions. 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 a computer-readable medium. The controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packet from the second communication device 450. The upper layer data packet from the controller / processor 475 may 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 operations.

[0614] The RIS 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 against channel blockage / fading. The first communication device 410 or the second communication device 450 can be referred to as the control node of the RIS 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 aspects in conjunction with the controller 491 of the RIS 490. Alternatively, 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 aspects in conjunction with the controller 491 of the RIS 490.

[0615] The first communication device 410 and / or the second communication device 450 use the RIS 490 for communication, sensing, and / or positioning functions. Information about the RIS 490 can be known to the network based on network planning, and the base station can provide the location of the RIS 490 and other information about the RIS 490 to other nodes (e.g., terminals in the cell). For example, the base station can transmit information about the RIS 490 in the system information. Terminals within the coverage area of the cell can receive the system information to discover the presence, location, capabilities, or other information about the RIS 490.

[0616] In a transmission where the first communication device 410 and / or the second communication device 450 use the RIS 490 for communication, at the RIS 490, a plurality of resonant elements form the RIS surface 492 and 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 reflect the received signal directionally) the corresponding received signal. The controller 491 can configure the phase or amplitude change by applying precoding weights to each resonant element so that the RIS 490 can re-radiate an output beam in different directions given a specific input beam.

[0617] In some cases, when the RIS 490 operates passively to only reflect or refract a beam from a transmitter to a receiver, the RIS 490 can operate as a near-passive device with little power consumption. In some cases, the direction of reflection or refraction can be controlled by a control node or a network controller.

[0618] In the transmission from the control node and the RIS 490, in the DL, at the RIS 490, the controller 491 can receive the signal from the control node and further process the received signal (e.g., digitize the received signal). In the UL, at the RIS 490, in response to the information from the control node or the RIS 490 data update, the information / data from the controller 491 is sent or provided to the control node.
