Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a method and device for determining spatial filtering parameters. Background Art

[0002] In the existing NR (New Radio) protocol, the first path (the first detected path) is used for timing advance (Timing Advance, T ADV ), calculation of UE (User Equipment) receive-transmit time difference (UE Rx–Tx time difference), calculation of downlink (DL) PRS (Positioning Reference Signal) reference signal received path power (RSRPP), calculation of gNB Rx–Tx time difference, measurement and / or reporting of the target device based on the configuration during LPP (LTE (Long-Term Evolution) Positioning Protocol), etc. In addition, when the UE determines the spatial filtering parameters of the transmitted signal, it can use the same spatial filtering parameters as the received signal based on the configuration. For example, the UE can use the same spatial filtering parameters as the received SSB (Synchronization Signal Block, or SS / PBCH block) or CSI (Channel State Information)-RS (Reference Signal) to send SRS (Sounding Reference Signal).

[0003] With the growing demand for perception, the trend of integrating sensing and communication capabilities in the network has become increasingly obvious. ITU-RWP 5D Working Group studied the application scenarios of Integrated Senging and Communication (ISAC) for 6G. The technical report 22.837 (Rel-19) on "Feasibility Study of Integrated Sensing and Communication" released by 3GPP (the 3rd Generation Partnership Project) describes 26 different use cases and integrates the potential requirements and key performance indicators (KPIs) of ISAC. The 3GPP RAN 102nd meeting adopted the study item (SI) of "Study on channel modelling for Integrated Sensing And Communication (ISAC) for NR", in which the focus of the study is to define channel modeling to support the detection and / or tracking of targets, including drones, people indoors and outdoors, cars (at least outdoors), automated guided vehicles (such as in indoor factories), objects that cause danger on roads / railways, etc. Summary of the invention

[0004] The inventors have found through research that it is difficult to reflect the path information of the received signal by using the same spatial filtering parameters to receive the reference signal and / or the uplink signal sent by using the same spatial filtering parameters as the received signal, and is not suitable for future, especially next generation mobile communication systems. For example, after the introduction of ISAC, it is difficult to reflect the link information of the detected and / or tracked target by reusing the existing scheme.

[0005] In view of the above problems, the present application provides a solution. In view of the above problem description, the NR system is used as an example. The present application is also applicable to scenarios such as LTE or LTE-A (Long-Term Evolution Advanced, enhanced long-term evolution) or 5G-A or future 6G systems, and obtains technical effects similar to those of the NR system; further, although the present application provides a specific implementation method for spatial filtering parameters, the present application can also be used in scenarios of other filtering parameters to obtain technical effects similar to those of spatial filtering parameters. Further, the use of a unified design scheme for different scenarios also helps to reduce hardware complexity and cost. Further, although the present application provides a specific implementation method for PRS, the present application can also be used in scenarios of other signals such as ISAC perception signals to obtain technical effects similar to those of PRS. 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. Further, although the original intention of the present application is for the downlink, the present application can also be used for the uplink to obtain technical effects similar to those of the downlink. 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.

[0438] The first 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.

[0439] The second communication 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 .

[0440] 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.

[0441] 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. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second 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 the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

[0442] In the transmission from the first communication device 450 to the second communication device 410, at the first communication 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 the L2 layer. Similar to the transmission function at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second communication device 410. 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 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.

[0443] 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. 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 the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
