Description

A method and device in a communication node used 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 selection method and device. Background Art Reference Signal (RS) is 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, the reconfigurable intelligent surface 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 The inventors have found through research that in existing communication systems, UE selection of reference signals depends on measurement. When the functions of different beams are different, the reference signals selected based on the measurement may not be appropriate. In particular, but not limited to, 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 selection of reference signals. Therefore, it is necessary to study the reference signal selection mechanism. In view of the above problems, the present application provides a solution. In the description of the above problems, the NR system is used as an example. The present application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) systems, and obtains technical effects similar to those of the NR system; in the description of the above problems, the NR system is used as an example. The present application is also applicable to scenarios such as the evolution system after NR, and obtains technical effects similar to those of the NR system; further, although the present application provides a specific implementation method for the downlink, the present application can also be used in scenarios such as the uplink to obtain technical effects similar to those of the downlink. Further, the use of a unified design scheme for different scenarios can also help reduce hardware complexity and cost. Further, although the present application provides a specific implementation method for RIS, the present application can also be used in other scenarios of downlink enhancement to obtain technical effects similar to those of RIS. Further, 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 this application is for the terminal and base station scenario, this application is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the relay and the base station, to achieve similar technical effects in the terminal and base station scenario. Further, 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, to achieve similar technical effects in the terminal and base station scenario. Further, although the original intention of this application is for the terrestrial network (Terrestrial Network, TN) scenario, this application is also applicable to the non-terrestrial network (Non-Terrestrial Network, NTN) communication scenario, to achieve similar technical effects in the TN scenario. In addition, the use of a unified solution for different scenarios also helps to reduce hardware complexity and cost.

In transmission from the second communication device 410 to the first communication device 450, at the second 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 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. 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 a different antenna 420. In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452.

The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping, channel coding processing, and the multi-antenna transmit processor 457 Digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing are performed, and 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 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. In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450.
