[0001] This application is a divisional application of the following original application:

[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 related to sidelinks 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 development 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. Research on NR-based V2X technology was initiated at the 3GPP RAN#80 plenary meeting, and at the first AdHoc meeting of RAN12019, it was agreed that the path loss between the transmitter and receiver in V2X would be used as a reference for V2X transmit power. Summary of the Invention

[0008] V2X's sidelink (SL) transmission resources occupy the system's uplink (UL) resources. In 3GPP NR systems, due to dynamic uplink / downlink configurations and the introduction of flexible symbols, the resources available for SL transmission are more fragmented. Furthermore, V2X resource pool configurations are static or semi-static, meaning that resources in the V2X resource pool may not always be available for SL transmission.

[0009] To address the aforementioned issues, this application discloses an SL resource allocation scheme, effectively resolving the impact of dynamic timeslot format configuration on SL transmission in NR systems. 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. Furthermore, although this application is initially intended for single-carrier communication, it can also be used for multi-carrier communication. Furthermore, although this application is initially intended for single-antenna communication, it can also be used for multi-antenna communication.

[0010] As an example, the interpretation of the terminology in this application is based on the definition in the 3GPP specification protocol TS36 series.

[0011] As an example, the interpretation of terms in this application is based on the definitions in the 3GPP specification protocol TS38 series.

[0014] This application discloses a method used in a first node of wireless communication, characterized by comprising:

[0015] Receive first information, the first information indicating a first symbol set;

[0016] Send the first signaling in the first symbol group;

[0017] The first wireless signal is transmitted in the second symbol group;

[0018] Wherein, the first symbol group belongs to the first symbol set; the first signaling indicates the second symbol group, the second symbol group comprising a positive integer number of multicarrier symbols; at least one multicarrier symbol among the positive integer number of multicarrier symbols included in the second symbol group belongs to the first symbol set, and at least one multicarrier symbol among the positive integer number of multicarrier symbols included in the second symbol group does not belong to the first symbol set; a first bit sequence is used to generate the first radio signal, the first bit sequence comprising a first bit subsequence and a second bit subsequence, the first bit subsequence being ordered in the first bit sequence prior to the second bit subsequence being ordered in the first bit sequence; the first bit subsequence is mapped to multicarrier symbols in the second symbol group that belong to the first symbol set, and the second bit subsequence is mapped to multicarrier symbols in the second symbol group that do not belong to the first symbol set.

[0019] As an example, the problem this application aims to solve is that for static or semi-static V2X resource pool configurations, dynamic time slot format configurations cause V2X resources to be unavailable at all times.

[0023] As an example, the method of this application is to establish an association between the second bit subsequence and multicarrier symbols that do not belong to the first symbol set.

[0024] As an example, the characteristic of the above method is that the multi-carrier symbols in the first symbol set are relatively stable available resources, which are used to transmit high-priority data or control signaling and HARQ feedback to ensure basic SL transmission functions.

[0025] As an example, the feature of the above method is that the multicarrier symbols in the second symbol group that do not belong to the first symbol set are relatively dynamic resources. The size, location and availability of these resources are very dynamic. They are used to transmit low-priority data. Even if the second node does not receive them, it will not have a significant impact on the basic transmission of SL, while also bringing additional gains.

[0301] Example 3

[0302] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), 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 herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY301. L2 layer 305 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 communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, 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., a remote UE, server, etc.).

[0316] Example 4

[0317] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0318] The first communication 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.

[0319] The second communication 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.

[0320] In the 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 L2 layer functionality. In the transmission from the first communication device 410 to the second 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 second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting 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 the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication 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.

[0321] 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 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 second communication 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 first communication 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 first communication device 410 to the second communication 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.

[0322] 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 the L2 layer. Similar to the transmission functions at the first communication device 410 described in the transmission from the first communication device 410 to the second 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, 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 first communication 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.

[0323] 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 receiving 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 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 second communication device 450 to the first communication 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.

[0502] As an example, the third node U5 is a base station, and the first node U3 and the second node U4 are both user equipment.

[0503] As an example, the third node U5 is a relay, and the first node U3 and the second node U4 are both user equipment.

[0504] In one embodiment, the third node U5 is a base station, the first node U3 is a relay, and the second node U4 is a user equipment.

[0508] As an example, detecting the first target signal in the third symbol group refers to receiving the first target signal based on blind detection. That is, the first node U3 receives the signal on the third symbol group and performs a decoding operation. If the decoding is determined to be correct according to the CRC bits, it is determined that the first target signal has been successfully received on the third symbol group; otherwise, it is determined that the first target signal has not been successfully detected on the third symbol group.

[0509] As an example, detecting the first target signal in the third symbol group refers to receiving the first target signal based on coherent detection. That is, the first node U3 uses the RS sequence corresponding to the first target signal to coherently receive the wireless signal on the third symbol group and measures the energy of the signal obtained after coherent reception. If the energy of the signal obtained after coherent reception is greater than a third given threshold, it is determined that the first target signal has been successfully received on the third symbol group; otherwise, it is determined that the first target signal has not been successfully detected on the third symbol group.

[0510] As an example, detecting the first target signal in the third symbol group refers to receiving the first target signal based on energy detection. That is, the first node U3 senses the energy of the wireless signal in the third symbol group and averages it over time to obtain the received energy. If the received energy is greater than a fourth given threshold, it is determined that the first target signal has been successfully received in the third symbol group; otherwise, it is determined that the first target signal has not been successfully detected in the third symbol group.
