[0004] --Original application title: A method and apparatus used in a node for wireless communication Technical Field

[0005] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus for accompanying links in wireless communication. Background Technology

[0006] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to conduct research on New Radio (NR) (or Fifth Generation, 5G). The 3GPP RAN #75 plenary meeting adopted the NR WI (Work Item), and began the standardization work of NR.

[0007] In response to the rapidly developing Vehicle-to-Everything (V2X) services, 3GPP has initiated standards development and research within the NR framework. Currently, 3GPP has completed the requirements definition for 5G V2X services, which are incorporated into standard TS22.886. 3GPP has identified and defined four major use case groups for 5G V2X services: Vehicles Platnooning, Extended Sensors, Advanced Driving (semi / fully automated driving), and Remote Driving. The NR V2X Study Item (SI) was approved at 3GPP RAN#80 plenary meeting. Summary of the Invention

[0008] Compared to existing LTE V2X systems, a significant feature of NR V2X is its support for multicast and unicast, as well as HARQ (Hybrid Automatic Repeat Request) and CSI (Channel Status Information) feedback. Furthermore, NR V2X allows user equipment to autonomously select transmission resources and implements corresponding collision avoidance or mitigation mechanisms. The design of CSI and / or HARQ feedback requires specific solutions.

[0009] To address the aforementioned problems, this application discloses a solution. It should be noted that, unless otherwise specified, the embodiments and features described in the user equipment of this application can be applied to the base station, and vice versa. Unless otherwise specified, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other.

[0010] This application discloses a method used in a first communication node for wireless communication, characterized by comprising:

[0011] Signaling monitoring is performed in the first time window, and X1 signaling messages are detected during the signaling monitoring process, where X1 is a non-negative integer.

[0012] The first resource set is determined from the first alternative resource pool;

[0013] Send the first signaling;

[0014] Send a first wireless signal in the first resource set;

[0015] Wherein, the X1 signaling messages and X1 target parameters are used to determine Y1 sets of candidate resources from the first candidate resource pool, where Y1 is a non-negative integer; the first resource set is a set of candidate resources other than the Y1 sets of candidate resources in the first candidate resource pool; the first signaling message is used to determine the time-frequency resources occupied by the first wireless signal; the end time of the first time window is not later than the start time of the first signaling message; whether the first wireless signal carries first control information is used to determine the X1 target parameters.

[0016] As an example, the problem this application aims to solve is: in the V2X user equipment autonomously selects transmission resources mode, how to avoid or reduce the occurrence of collisions during the transmission of accompanying link feedback information (such as CSI, HARQ) through signaling monitoring methods, thereby improving the transmission efficiency of feedback information, and thus improving the throughput and system capacity of data transmission.

[0017] As an example, the essence of the above method is that X1 signaling messages are X1 SCIs (Sidelink Control Information), the first control information is feedback information (such as CSI, HARQ), and X1 target parameters are signaling monitoring thresholds. These thresholds are used to exclude Y1 candidate resource sets from the first candidate resource pool. The first communication node selects one candidate resource set from the remaining candidate resource sets in the first candidate resource pool to transmit the first wireless signal; this selected candidate resource set is the first resource set. The signaling monitoring threshold is related to whether the first wireless signal carries feedback information. The advantage of using this method is that when the user equipment autonomously selects transmission resources, a reasonably designed signaling monitoring threshold can effectively avoid or reduce accompanying link feedback information, thereby improving the transmission efficiency of feedback information and ultimately increasing data transmission throughput and system capacity.

[0018] According to one aspect of this application, the above method is characterized by comprising:

[0023] According to one aspect of this application, the above method is characterized in that the priority of the first wireless signal corresponds to a target priority index, the target priority index being used to determine the X1 target parameters; when the first wireless signal carries only the first control information, the target priority index is equal to a first priority index; when the first wireless signal carries only information other than the first control information, the target priority index is equal to a second priority index.

[0024] As an example, the essence of the above method is that the X1 target parameters are the thresholds for signaling monitoring, the thresholds for signaling monitoring are related to the priority of the first wireless signal, and the priority of the first wireless signal is related to whether the first wireless signal carries feedback information.

[0025] According to one aspect of this application, the above method is characterized in that, when the first wireless signal carries the first control information and information other than the first control information, the target priority index is equal to the second priority index, or the target priority index is equal to the smaller of the first priority index and the second priority index, or the target priority index is equal to the larger of the first priority index and the second priority index.

[0028] As an example, the essence of the above method is that the first communication node first selects Y2 candidate resource sets from the remaining candidate resource sets in the first candidate resource pool, and satisfies the condition that the ratio of Y2 divided by Y is not less than a first threshold; then, the first communication node selects the first resource set from the Y2 candidate resource sets.

[0256] Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and control plane. Figure 3The radio protocol architecture for a second communication node device (UE or RSU in V2X) and a first communication node device (gNB, eNB), or between two UEs, is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the second and first communication node devices, as well as between the two UEs, via PHY301. In the user plane, L2 layer 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the first communication node device on the network side. Although not illustrated, the second communication node device may have several upper layers above L2 layer 305, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.). PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides header compression for upper layer packets to reduce radio transmission overhead, provides security through packet encryption, and provides cross-cell mobility support between the first and second communication node devices. RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the second communication node devices. MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the second and first communication node devices is largely the same for physical layer 301 and L2 layer 305, but header compression functionality for the control plane is absent. The control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (L3). RRC sublayer 306 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the first and second communication node devices.

[0265] Example 4

[0266] Example 4 illustrates a schematic diagram of a first communication node device and a second communication node device according to this application, as shown in the attached diagram. Figure 4 As shown.

[0267] Figure 4 This is a block diagram of a first communication node device 450 and a second communication node device 410 communicating with each other in the access network.

[0268] The first communication node device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0269] The second communication node device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0270] In the transmission from the second communication node device 410 to the first communication node device 450, at the second communication node device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication node device 410 to the second communication node 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 node device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication node 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). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the first communication node device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0271] In the transmission from the second communication node device 410 to the first communication node device 450, at the first communication node device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations 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 receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication node device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication node device 410 over 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 Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication node device 410 to the first communication node device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0272] In the transmission from the first communication node device 450 to the second communication node device 410, at the first communication node 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 node device 410 described in the transmission from the second communication node device 410 to the first communication node 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, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication node device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0273] In the transmission from the first communication node device 450 to the second communication node device 410, the function at the second communication node device 410 is similar to the receiving function at the first communication node device 450 described in the transmission from the second communication node device 410 to the first communication node device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication node device 450 to the second communication node device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.
