Description

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

[0002] --The original application was filed on November 12, 2018.

[0003] --Original application number: 201811341933.1

[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, multiple antennas, and broadband 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. Research on NR-based V2X technology was initiated at the 3GPP RAN#80 plenary meeting. Summary of the Invention

[0008] To meet new service demands, compared to LTE V2X systems, NRV2X systems offer key technological features such as higher throughput, higher reliability, lower latency, longer transmission distance, more accurate positioning, greater variability in packet size and transmission cycle, and more effective coexistence with existing 3GPP and non-3GPP technologies. Existing LTE-V2X systems operate only in broadcast mode, with transmission modes and resource configurations primarily geared towards long-term, periodic services. As a crucial area within vertical industries, NR-V2X services not only need to support multicast and unicast transmissions but also require more flexible, bursty service capabilities.

[0009] To address the issue of NRV2X supporting non-periodic, bursty services, this application discloses a resource allocation solution. After user equipment reserves periodic resources using traditional sensing methods, it can flexibly release some of the reserved resources according to the bursty data needs of the target user. This provides a more flexible resource allocation method, particularly in scenarios involving automated queuing driving.

[0010] It should be noted that, unless otherwise specified, the embodiments and features in the user equipment of this application can be applied to the base station, and vice versa.

[0386] Example 3

[0387] 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.

[0388] 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 User Equipment (UE) and Base Station Equipment (gNB or eNB) 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. Layers above Layer 1 belong to higher layers. The 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 UE and the base station equipment 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 base station equipment on the network side. Although not illustrated, the user equipment 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 base station equipment for user equipment. 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 (Hybrid Automatic Repeat reQuest). 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 among user equipment. MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for user equipment and base station equipment 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 a Layer 3 (L3) RRC (Radio Resource Control) sublayer 306. RRC sublayer 306 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between base station equipment and user equipment.

[0411] Example 4

[0412] 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.

[0413] 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.

[0414] 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.

[0415] 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.

[0416] 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.

[0417] 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.

[0418] 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.

[0973] Example 11 illustrates a schematic diagram of the relationship between a target resource pool and a first air interface resource group according to an embodiment of this application, as shown in the attached diagram.

[0974] In Example 11, if the second priority is lower than the first priority, the target resource pool and the first air interface resource group are orthogonal; if the second priority is higher than the first priority, the target resource pool and the first air interface resource group overlap.

[0975] As an example, the second priority being higher than the first priority means that the priority of the service carried by the first wireless signal is higher than the priority of the service carried by the wireless signal that the sender of the first control information will transmit on the first air interface resource.

[0976] As an example, the second priority being higher than the first priority means that the latency requirement of the service carried by the first wireless signal is higher than the latency requirement of the service carried by the wireless signal that the sender of the first control information will transmit on the first air interface resource.

[0977] As an example, the second priority being higher than the first priority means that the sender of the first control information will not transmit wireless signals on the first air interface resource.

[0981] As an example, the second priority being lower than the first priority means that the priority of the service carried by the first wireless signal is lower than the priority of the service carried by the wireless signal that the sender of the first control information will transmit on the first air interface resource.

[0982] As an example, the second priority being lower than the first priority means that the latency requirement of the service carried by the first wireless signal is lower than the latency requirement of the service carried by the wireless signal that the sender of the first control information will transmit on the first air interface resources.

[0983] As an example, the second priority being lower than the first priority means that the sender of the first control information does not allow the first node to transmit wireless signals on the first air interface resource.

[0984] As an example, the second priority being lower than the first priority means that a second type threshold corresponding to the second priority is lower than a first type threshold corresponding to the first priority.

[0985] As an example, the second priority being lower than the first priority means that the first control signal does not include the identifier of the first node.

[0986] As an example, if the second priority is equal to the first priority, the target resource pool overlaps with the first air interface resource group.

[0987] As an example, the second priority being equal to the first priority means that the priority of the service carried by the first wireless signal is equal to the priority of the service carried by the wireless signal that the sender of the first control information will transmit on the first air interface resource.

[0988] As an example, the second priority being equal to the first priority means that the latency requirement of the service carried by the first wireless signal is equal to the latency requirement of the service carried by the wireless signal that the sender of the first control information will transmit on the first air interface resource.

[0989] As an example, the second priority being equal to the first priority means that the sender of the first control information allows the first node to transmit wireless signals on the first air interface resource.

[0990] As an example, the second priority being equal to the first priority means that a second type threshold corresponding to the second priority is equal to a first type threshold corresponding to the first priority.

[0991] As an example, the second priority being equal to the first priority means that the first control signal includes the identifier of the first node.

[0992] As an example, any time-frequency resource unit in the target resource pool does not overlap with any time-frequency resource unit in the first air interface resource group.

[0993] As an example, the first candidate time-frequency resource unit is any one of the Z4 time-frequency resource units included in the target resource pool.

[0994] As an example, the first candidate time-frequency resource unit does not overlap with any time-frequency resource unit in the first air interface resource group simultaneously in the time domain and in the frequency domain.

[0995] As one embodiment, the target resource pool includes the first air interface resource group.
