Description

A method and apparatus in a node used for wireless communication and sensing TECHNICAL FIELD

[0001] The present application relates to a signal transmission method and apparatus in a wireless communication system, and in particular, to a method and apparatus related to sensing in a wireless communication system. BACKGROUND

[0002] Application scenarios of future wireless communication systems are increasingly diversified, and different application scenarios have different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the research on New Radio (NR) (or 5G) was started at the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) #72 plenary meeting. With the wide application of 5G, new business models and new application scenarios are emerging, and the existing 5G standard cannot fully meet the new requirements, so 3GPP is preparing to start the preliminary research on 6G.

[0003] With the diversification of application scenarios and the emergence of new business models, the existing link direction configuration scheme cannot meet the needs of 6G, so 6G needs to explore a more flexible and unified link direction configuration scheme. At the same time, with the development of mobile communication, especially the application of 5G active antenna array, the architecture of communication system and sensing system tends to be consistent, and the integration trend of communication and sensing capabilities in the network is gradually obvious. Integrated Sensing And Communication (ISAC) technology refers to the unified design of communication and sensing functions through air interface and protocol joint design, time-frequency-space resource reuse, hardware device sharing, etc., so that the wireless network can realize high-precision and fine-grained sensing functions while performing high-quality communication interaction, thereby improving the spectrum efficiency, energy efficiency and hardware efficiency of the system, obtaining integration gain, in addition, through the mutual assistance and cooperation between communication and sensing functions, the performance of each other can be improved, thereby obtaining coordination gain. SUMMARY

[0004] 5G NR system started SI (study item) and WI (work item) to support SBFD (Subband non-overlapping Full Duplex) in Rel-18 and Rel-19 respectively. The SBFD in Rel-18 and Rel-19 is to configure subbands that can be used for uplink transmission in the existing downlink time domain resources, but does not substantially change the distribution of link directions or the format of time slots of the entire cell or the entire carrier. At the same time, due to the limitation of the existing carrier-level link direction distribution, the link direction in the SBFD subband is fixed. In addition, the SBFD of 5G only supports unpaired spectrum (TDD (Time Division Duplex) spectrum) and does not support paired spectrum (FDD (Frequency Division Duplex) spectrum). At the same time, in the future 6G system, wireless signals for sensing will also be embedded into the existing more flexible full duplex system to realize the scenarios of sensing-assisted communication and joint work of sensing communication, and the design of time slot format and frame structure needs to be redesigned and considered based on the above scenarios.

[0005] To solve the above problems, a solution is disclosed in the present application. It should be noted that in the description of the present application, only flexible link direction configuration is taken as a typical application scenario or example; the present application is also applicable to 6G networks or other scenarios facing similar problems in the future (for example, there are scenarios where the link direction changes, or other scenarios that support multi-level configuration of transmission direction, or base stations or user equipment with stronger capabilities, such as scenarios that support same-frequency full duplex, or for different application scenarios such as eMBB (Enhanced Mobile Broadband), URLLC (Ultra Reliable Low Latency Communication), full duplex network, non-terrestrial network, integrated sensing network, intelligent metasurface, terahertz network, similar technical effects can also be achieved. In addition, using a unified solution for different scenarios (including but not limited to eMBB, URLLC, full duplex network, non-terrestrial network, integrated sensing network, intelligent metasurface, terahertz network scenarios) or different application parameters can also help to reduce hardware complexity and cost.

[0283] Embodiment 4

[0284] 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 and a second communication device 450 communicating with each other in an access network.

[0285] The first 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.

[0286] The second 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.

[0287] In transmissions from the first communication device 410 to the second communication device 450, at the first communication device 410, upper layer packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements functionality of L2. In DL, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for 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 Ll (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 450 and mapping onto signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-ary phase shift keying (M-PSK), M-ary quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding and beamforming processing, to generate one or more parallel streams. The transmit processor 416 then maps to each of the parallel streams to subcarriers, multiplexes the modulated symbols in time domain and / or frequency domain with reference signals (e.g., pilot) and then performs an inverse fast Fourier transform (IFFT) to generate time domain multicarrier symbol streams. The multi-antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time domain multicarrier symbol streams. Each transmitter 418 converts the baseband multicarrier symbol streams provided by the multi-antenna transmit processor 471 into radio frequency signals that are transmitted via the corresponding antennas 420.

[0288] In transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and converts the RF stream into a baseband multi-carrier symbol stream that provides to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions of the LI. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 converts the baseband multi-carrier symbol stream from the receive analog precoding / beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed by the receive processor 456, where the reference signals will be used for channel estimation, and the data signals are recovered after multi-antenna detection in the multi-antenna receive processor 458 for any parallel streams destined to the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receive processor 456 and generate soft decisions. The receive processor 456 then 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 channels. 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. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer-readable medium. In the DL, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2. Various control signals can also be provided to the L3 for L3 processing. The controller / processor 459 is also responsible for error detection using an ACK and / or negative ACK (NACK) protocol to support HARQ operations.

[0289] 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 upper layer packets to a controller / processor 459. The data source 467 represents all protocol layers above L2. Similar to the transmit function described at the first communication device 410 in the DL, the controller / processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations for the first communication device 410, implements L2 layer functionality for the user plane and 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, in conjunction with a multi-antenna transmit processor 457, performs modulation mapping, channel coding processing, digital multi-antenna spatial pre-coding including codebook-based and non-codebook-based precoding, and beamforming processing, and then the transmit processor 468 generates parallel streams of symbols that are modulated onto different carriers, and the modulated symbol streams are then provided to different antennas 452 via transmitters 454 after analog pre-coding / beamforming operations in the multi-antenna transmit processor 457.
