In 2020, 5.5G industry vision for 5G evolution was first presented by the industry. In April 2021, 3GPP (3rd Generation Partner Project) officially identified 5.5G name of 5G evolution as 5G-Advanced, started the standardization process, and planned to define 5G-Advanced technical specifications through Rel-18 (Release-18), Rel-19 and Rel-20. At the end of 2021, the first 28 topics of Rel-18 were set up, and the research and standardization of 5.5G technology entered a substantial stage. Future Rel-19 and Rel-20 will further explore new 5G-Advanced services and architectures.

Reconfigurable Intelligent Surface (RIS) is an artificial electromagnetic surface structure with programmable electromagnetic properties, containing a large number of independent low-cost passive subwavelength resonant units. Each RIS unit has an independent electromagnetic wave modulation capability, and the response of each unit to the radio signal can be controlled by changing parameters of the RIS unit, spatial distribution, etc., such as phase, amplitude, and polarization. Through the mutual superposition of the radio response signals of a large number of RIS units, specific beam propagation properties are formed on the macro level, thus forming a flexible and controllable shaped beam to achieve the effect of eliminating the coverage blind zones, enhancing the edge coverage and increasing the rank of the multi-stream transmission. RIS technology is characterized by low cost, low energy consumption, programmability, ease of deployment, and high shaping gain with larger antenna scale, which is regarded as a key technology for research in the 5G-Advanced phase and one of the core visions for 6G.

SUMMARY

In the existing standards, whether it is a time division duplex or frequency division duplex system, after transmission and reception of link calibration of the UE is completed, the uplink transmitting beam can be determined according to the downlink receiving beam based on a spatial relation between downlink reception and uplink transmission. However, since the uplink and downlink in a frequency division duplex system use different frequency bands for communications at the same moment, and the RIS can only perform beamforming for a specific beam direction at each moment, the spatial relation between the downlink reception and the uplink transmission of the UE in the RIS coverage in a frequency division duplex scenario may be different from the conventional scenario without introducing the RIS, and the traditional way of determining the uplink spatial transmission parameters by the spatial receiving parameters of the downlink reference signal may no longer be applicable.

To address the above problem, the present application provides a solution. It should be noted that NR (New Radio) system is used as an example in response to the above problem description, and the present application is equally applicable to, for example, a scenario of a future 6G system, to achieve technical effects similar to that of the NR system; further, while the present application was originally intended for RIS scenarios, the present application can be applied to other non-RIS scenarios as well; further, for different scenarios (e.g., other non-RIS scenarios including, but not limited to, capacity enhancement systems, systems for proximity communications, unlicensed spectrum communications, IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) network, Internet of Vehicles (IoV), etc.), adopting a unified design scheme also helps reduce hardware complexity and cost. If no conflict is incurred, embodiments in any node in the present application and the characteristics of the embodiments are also applicable to any other node, and vice versa. And the embodiments in the present application and the characteristics in the embodiments can be arbitrarily combined if there is no conflict.

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to one embodiment of the present application, as shown in FIG. 4. FIG. 4 is a block diagram of a first communication device 410 in communication with a second communication device 450 in an access network.

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.

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.

In a transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, a higher-layer packet from the core network is provided to the controller/processor 475. The controller/processor 475 implements L2 functionality. In DL transmission, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation for the second communication device 450 based on various priorities. The controller/processor 475 is also in charge of HARQ operation, retransmission of a lost packet, and a signaling to the second communication node 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the LI layer (that is, PHY). The transmitting processor 416 implements encoding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450, as well as mapping of signal clusters based on various modulation schemes such as 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 transmitting processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more parallel streams. The transmitting processor 416 then maps cach of the parallel streams to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot frequency) in time domain and/or frequency domain, and subsequently uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas 420.

In a transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, cach receiver 454 receives signals through its corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided 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 receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver 454. The receiving processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming from time domain into frequency domain using Fast Fourier Transform (FFT). In frequency domain, a physical-layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any second communication device 450-targeted parallel stream. Symbols on each parallel stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the first communication node 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of the L2.

The controller/processor 459 can be connected to a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In downlink (DL) transmission, the controller/processor 459 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2, or various control signals can be provided to the L3 layer for processing. The controller/processor 459 is also responsible for error detection using ACKnowledgement (ACK) and/or Negative ACKnowledgement (NACK) protocols to support HARQ operations.

In a transmission from the second communication device 450 to the first communication device 410, the data source 467 is used at the second communication device 450 to provide upper layer data packets to the controller/processor 459. The data source 467 represents all protocol layers above the L2. Similar to a transmitting function of the first communication device 410 described in DL transmission, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the first communication device 410 so as to provide the L2 functions used for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operation, retransmission of a lost packet, and a signaling to the first communication device 410. The transmitting processor 468 performs modulation mapping and channel coding processing, the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, then the transmitting processor 468 modulates the generated parallel stream into a multicarrier/single-carrier symbol stream, which undergoes an analog precoding/beamforming operation in the multi-antenna transmitting processor 457 before being provided to the different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmitting processor 457 into an RF symbol stream, and then provides it to the antenna 452.

In a 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 receiving function at the second communication device 450 described in a transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal via a 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 function of L1. The controller/processor 475 implements L2 function. The controller/processor 475 can be connected with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. The controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the second communication device 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network. The controller/processor 475 can also perform error detection using ACK and/or NACK protocols to support HARQ operation.
