Description

Technical Field

[0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a power control method and device. Background Art

[0002] With the development of mobile communications, especially the application of 5G active antenna arrays, the architecture of communication systems and perception systems are becoming more consistent, and the integration trend of communication and perception capabilities in the network is becoming increasingly obvious. Communication and perception integration technology, also known as Integrated Sensing And Communication (ISAC) technology, refers to the unified design of communication and perception functions through joint design of air interfaces and protocols, reuse of time-frequency and space resources, and sharing of hardware devices, so that wireless networks can achieve high-precision and refined perception functions while performing high-quality communication interactions, thereby improving the system's spectrum efficiency, energy efficiency, and hardware efficiency, and obtaining integration gain. In addition, through the mutual assistance and cooperation between the two functions of communication and perception, the performance of each other can be improved, thereby obtaining coordination gain.

[0003] In the 5G Rel-18 (Release-18) stage, 3GPP (the 3rd Generation Partnership Project) SA1 (Services & Systems Aspects 1) has carried out extensive and comprehensive ISAC scenario use case research; in June 2023, the Feasibility Study on Integrated Sensing and Communication (Technical Report, TR) 22.837 (Rel-19) passed by the 3GPP SA#100 Plenary Meeting described the three major scenarios of object detection and tracking, environment monitoring and motion monitoring supported in ISAC, with a total of 32 use cases; in December 2023, the 3GPP RAN (Radio Access Network) #102 Plenary Meeting passed the Study on channel modelling for Integrated Sensing And Communication (ISAC) for The SI (Study Item) of NR (ISAC channel modeling study for NR), RAN1 working group will also aim to support object detection and tracking scenarios in the Rel-19 stage, taking the channel model in 38.901 as the starting point, and lead the research on ISAC channel modeling; ISAC is also regarded as the key potential technology development direction and one of the six main application scenarios in the 6G stage. Summary of the invention

[0004] In ISAC, the sensing mode can be divided into single-station sensing with a single transmitter and receiver and dual-station sensing with separate transmitter and receiver. In the case of single-station sensing, the same node performs the sending and receiving of the sensing signal, and the node that performs the sending and receiving of the sensing signal can be a base station or a UE (User Equipment). In dual-station sensing, the sending and receiving of the sensing signal are performed by two nodes separated in space, and the two nodes can be two base stations, two UEs, or a base station and a UE.

[0005] In the case of single-station sensing with a single transmitter and receiver, i.e., the receiving and transmitting nodes are the same, the receiving antenna needs to receive the reflected echo of the sensing signal to extract relevant information of the sensing target, such as distance, speed, direction, and shape, etc. At the same time, the receiving antenna may also need to receive the communication signal to obtain communication information. Therefore, in the single-station sensing model with a single transmitter and receiver, reducing the interference of the communication signal on the echo signal is a problem worth studying. In the dual-station sensing with separate transmitter and receiver, i.e., the receiving and transmitting nodes are spatially separated, the receiving node receives the sensing signal from the transmitting node, amplifies and analyzes it, and provides the relevant information of the target to the transmitting node through the feedback signal. Therefore, in the dual-station sensing model with separate transmitter and receiver, improving the transmission reliability of the feedback signal is a problem worth studying.

[0006] In view of the above problems, the present application discloses a solution. It should be noted that, in the description of the above problems, the NR (New Radio) system is used as an example, and the present application is also applicable to scenarios such as the future 6G system, and obtains technical effects similar to the NR system; further, although the original intention of the present application is for the ISAC scenario, the present application can also be applied to other non-ISAC scenarios; further, for different scenarios (such as other non-ISAC scenarios, including but not limited to RIS (Reconfigurable Intelligent Surface, Reconfigurable Intelligent Super Surface), Vehicle to Everything (V2X), Side Link (SideLink, SL), NCR (Network Control Repeater, Network Control Repeater) capacity enhancement system, short-range communication system, NTN (Non Terrestrial Network, Non-terrestrial Network), IoT (Internet of Things, Internet of Things), URLLC (Ultra Reliable Low Latency Communication, Ultra Robust Low Latency Communication) network, etc.), a unified design scheme is also helpful to reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in any node of the present application can be applied to any other node.

[0426] Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The wireless protocol architecture of the control plane 300 for the first communication node device (RSU (Road Side Unit) in UE or V2X (Vehicle to Everything), vehicle-mounted device or vehicle-mounted communication module) and the second node device (gNB, RSU in UE or V2X, vehicle-mounted device or vehicle-mounted communication module), or between two UEs is presented in three layers: Layer 1 (Layer 1, L1), Layer 2 (Layer 2, L2) and Layer 3 (Layer 3, L3). L1 is the lowest layer and implements various PHY (PHYsical layer) signal processing functions. L1 will be referred to as PHY 301 in this article. L2305 is above PHY 301 and is responsible for the link between the first node device and the second node device, or between two UEs through PHY 301. L2305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets, and provides inter-zone mobility support for the first communication node device between the second communication node device. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception caused by HARQ (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in L3 in the control plane 300 is responsible for obtaining radio resources (ie, radio bearers) and configuring lower layers using RRC signaling between the second communication node device and the first communication node device.The wireless protocol architecture of the user plane 350 includes layer 1 (L1) and layer 2 (L2). The wireless protocol architecture for the first communication node device and the second communication node device in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in L2355, the RLC sublayer 353 in L2355, and the MAC sublayer 352 in L2355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce wireless transmission overhead. L2355 in the user plane 350 also includes a SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS (Quality of Service) flows and data radio bearers (DRBs) to support business diversity.

[0434] Example 4

[0435] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in the attached figure. Figure 4 Attached Figure 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.

[0436] 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 .

[0437] 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.

[0438] In transmission from the first communication device 410 to the second communication device 450, at the first 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 L2. In DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the 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 L1 (i.e., physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, 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-PSK, M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding and beamforming processing, to generate one or more parallel streams. The transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., 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 different antennas 420.

[0439] In the 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 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 L1. 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, where 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 parallel stream with the second communication device 450 as the destination. The symbols on each parallel 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 first 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 L2. The controller / processor 459 may be associated with a memory 460 storing program codes and data. The memory 460 may be referred to as a computer-readable medium. In DL, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover the upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above L2. Various control signals may also be provided to L3 for L3 processing. The controller / processor 459 is also responsible for error detection using ACKnowledgement (ACK) and / or negative ACKnowledgement (Negative ACKnowledgement, NACK) protocols to support HARQ operations.

[0440] 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 data packets to the controller / processor 459. The data source 467 represents all protocol layers above L2. Similar to the transmission function at the first communication device 410 described in DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, and implements L2 functions for the user plane and the control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first 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 parallel 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.

[0441] In the 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 reception function at the second communication device 450 described in the transmission from the first communication device 410 to the second 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 L1. The controller / processor 475 implements the L2 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. The controller / processor 475 provides demultiplexing between transmission and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 can be provided to the core network. The controller / processor 475 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
