Description

A method and device used in a communication node for wireless communication Technical Field The present application relates to a transmission method and device in a wireless communication system, and in particular to a reference signal processing method and device. Background Art Reference signals are widely used for channel measurement of user equipment (UE), and / or for cell-level mobility, and / or for beam-level mobility, and / or for determining spatial parameters of uplink (UL) signals. The existing network deployment still has problems such as coverage blind spots and poor edge coverage. Reconfigurable Intelligent Surface (RIS) is an artificial electromagnetic surface structure with programmable electromagnetic properties. It contains a large number of independent low-cost passive subwavelength resonant units. Through the superposition of 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, which can eliminate coverage blind spots, enhance edge coverage, and increase the rank of multi-stream transmission. Therefore, reconfigurable intelligent metasurface is regarded as a key technology in the 5G-Advanced stage research and one of the core visions of 6G due to its low cost, low energy consumption, programmability, easy deployment, and high shaped gain with a larger antenna scale. Summary of the invention Through research, the inventors found that in existing communication systems, beam coverage has strong directionality. When the beam direction is changed (for example, by changing the beam direction through RIS), the spatial relationship of the beam will change, which is not conducive to the UE's processing of reference signals, especially but not limited to the reception and / or selection of reference signals; therefore, it is necessary to study the reference signal when the beam direction is changed. In view of the above problems, the present application provides a solution. In the description of the above problems, the NR (New Radio) system is used as an example. The present application is also applicable to scenarios such as the future 6G system, and obtains technical effects similar to those of the NR system; further, although the present application provides a specific implementation method for the downlink reference signal, the present application can also be used in scenarios such as the uplink reference signal to obtain technical effects similar to those of the downlink reference signal. Furthermore, the use of a unified design scheme for different scenarios also helps to reduce hardware complexity and cost. Furthermore, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 port to obtain technical effects similar to those of the Uu air interface. Furthermore, although the original intention of the present application is for the terminal and base station scenarios, the present application is also applicable to V2X (Vehicle-to-Everything) scenarios, communication scenarios between the terminal and the relay, and the relay and the base station, to obtain technical effects similar to those in the terminal and base station scenarios. Furthermore, although the original intention of this application is for the terminal and base station scenario, this application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario, and achieves similar technical effects in the terminal and base station scenario. Furthermore, although the original intention of this application is for the terrestrial network (TN) scenario, this application is also applicable to the non-terrestrial network (NTN) communication scenario, and achieves similar technical effects in the TN scenario. In addition, the use of a unified solution for different scenarios can also help reduce hardware complexity and costs.

The controller / processor 475 implements the functionality of the L2 layer. In transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first 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 410, 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-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it 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.

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 spatial 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 transmits the multi-antenna transmit processor 457 to provide The baseband symbol stream is converted into a radio frequency symbol stream and then provided to the antenna 452.
