Description

一种被用于无线通信的通信节点中的方法和装置A method and device used in a communication node for wireless communication 技术领域Technical Field
本申请涉及无线通信系统中的传输方法和装置，涉及针对大数据量尤其是高速率低时延业务的方法和装置。The present application relates to a transmission method and device in a wireless communication system, and to a method and device for large data volumes, especially high-speed and low-latency services.
背景技术Background technique
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口(NR，New Radio)技术进行研究,在3GPP RAN#75次全会上通过了NR(New Radio，新空口)的WI(Work Item，工作项目)，开始对NR(New Radio)进行标准化工作。其中，XR是R18(Release 18)的一个重要研究方向。The application scenarios of future wireless communication systems are becoming more and more 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 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study the new radio (NR) technology, and the 3GPP RAN #75 plenary meeting passed the WI (Work Item) of NR (New Radio), and began to standardize NR (New Radio). Among them, XR is an important research direction of R18 (Release 18).
发明内容Summary of the invention
现有协议中，数据缓存上报(Buffer Status Reporting，BSR)过程被用于提供数据量的信息，一个BSR MAC(Medium Access Control，媒体接入控制)CE(Control Element，控制元素)携带的数据量信息被用于资源分配。XR业务包括VR(Virtual reality，虚拟现实)业务、AR(Augmented reality，增强现实)和MR(Mixed reality，混合现实)等，具有高速率，低时延的特点。除此之外，XR业务还具有数据量大的特点，需要对现有的BSR MAC CE进行增强，如果用于XR的BSR MAC CE和其MAC子头具备比现有的BSR MAC CE和其MAC子头更大的尺寸，根据现有的数据缓存上报机制进行资源分配时，比如上报逻辑信道组中优先级最高的逻辑信道，可能会导致配置的资源不足以发送XR的BSR，因此，需要对数据缓存上报机制进行增强。In the existing protocol, the buffer status reporting (BSR) process is used to provide information about the amount of data, and the amount of data information carried by a BSR MAC (Medium Access Control) CE (Control Element) is used for resource allocation. XR services include VR (Virtual Reality), AR (Augmented Reality) and MR (Mixed Reality), which have the characteristics of high speed and low latency. In addition, XR services also have the characteristics of large data volume, and the existing BSR MAC CE needs to be enhanced. If the BSR MAC CE and its MAC subheader used for XR have a larger size than the existing BSR MAC CE and its MAC subheader, when allocating resources according to the existing data buffer reporting mechanism, such as reporting the logical channel with the highest priority in the logical channel group, it may cause the configured resources to be insufficient to send the BSR of XR. Therefore, the data buffer reporting mechanism needs to be enhanced.
针对上述问题，本申请提供了一种数据缓存上报的解决方案。针对上述问题描述中，采用XR业务作为一个例子；本申请也同样适用于例如其他高数据速率业务的场景；进一步的，虽然本申请针对NR给出了具体的实施方式，但本申请也能被用于例如LTE(Long-Term Evolution，长期演进)的场景，取得类似NR的技术效果。进一步的，虽然本申请的初衷是针对Uu空口，但本申请也能被用于PC5口。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于V2X(Vehicle-to-Everything，车联网)场景，终端与中继，以及中继与基站之间的通信场景，取得类似的终端与基站场景中的技术效果。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于IAB(Integrated Access and Backhaul，集成接入和回传)的通信场景，取得类似的终端与基站场景中的技术效果。进一步的，虽然本申请的初衷是针对地面网络(Terrestrial Network，地面网络)场景，但本申请也同样适用于非地面网络(Non-Terrestrial Network，NTN)的通信场景，取得类似的TN场景中的技术效果。此外，不同场景采用统一解决方案还有助于降低硬件复杂度和成本。In view of the above problems, the present application provides a solution for data cache reporting. In the description of the above problems, XR service is used as an example; the present application is also applicable to scenarios such as other high data rate services; further, although the present application provides a specific implementation method for NR, the present application can also be used in scenarios such as LTE (Long-Term Evolution) to achieve similar technical effects as NR. Further, although the original intention of the present application is for the Uu air interface, the present application can also be used for the PC5 port. Further, although the original intention of the present application is for the terminal and base station scenario, the present application is also applicable to the V2X (Vehicle-to-Everything) scenario, the communication scenario between the terminal and the relay, and the relay and the base station, to achieve similar technical effects in the terminal and base station scenario. Further, although the original intention of the present application is for the terminal and base station scenario, the present application is also applicable to the IAB (Integrated Access and Backhaul) communication scenario to achieve similar technical effects in the terminal and base station scenario. Furthermore, although the original intention of this application is for terrestrial network (terrestrial network) scenarios, this application is also applicable to non-terrestrial network (NTN) communication scenarios, achieving similar technical effects in TN scenarios. In addition, the use of a unified solution for different scenarios can also help reduce hardware complexity and costs.

FIG3 is a schematic diagram illustrating an embodiment of a wireless protocol architecture for a user plane 350 and a control plane 300. FIG3 shows the wireless protocol architecture for the control plane 300 using three layers: layer 1, layer 2, and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. 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. 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 due to HARQ (Hybrid Automatic Repeat Request).

The controller/processor 475 implements the functionality of the L2 layer. In transmission from the second communication device 410 to the first 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 first communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to the first 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). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, 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-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with a reference signal (e.g., a 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 a different antenna 420.
在从所述第二通信设备410到所述第一通信设备450的传输中，在所述第一通信设备450处，每一接收器454通过其相应天线452接收信号。每一接收器454恢复调制到射频载波上的信息，且将射频流转化成基带多载波符号流提供到接收处理器456。接收处理器456和多天线接收处理器458实施L1层的各种信号处理功能。多天线接收处理器458对来自接收器454的基带多载波符号流进行接收模拟预编码/波束赋型操作。接收处理器456使用快速傅立叶变换(FFT)将接收模拟预编码/波束赋型操作后的基带多载波符号流从时域转换到频域。在频域，物理层数据信号和参考信号被接收处理器456解复用，其中参考信号将 被用于信道估计，数据信号在多天线接收处理器458中经过多天线检测后恢复出以所述第一通信设备450为目的地的任何空间流。每一空间流上的符号在接收处理器456中被解调和恢复，并生成软决策。随后接收处理器456解码和解交错所述软决策以恢复在物理信道上由所述第二通信设备410发射的上层数据和控制信号。随后将上层数据和控制信号提供到控制器/处理器459。控制器/处理器459实施L2层的功能。控制器/处理器459可与存储程序代码和数据的存储器460相关联。存储器460可称为计算机可读媒体。在从所述第二通信设备410到所述第二通信设备450的传输中，控制器/处理器459提供输送与逻辑信道之间的多路分用、包重组装、解密、标头解压缩、控制信号处理以恢复来自核心网络的上层数据包。随后将上层数据包提供到L2层之上的所有协议层。也可将各种控制信号提供到L3以用于L3处理。In the transmission from the second communication device 410 to the first communication device 450, at the first 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 the L1 layer. 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 is converted into a baseband multi-carrier symbol stream. The data signal is used for channel estimation, and after multi-antenna detection in the multi-antenna receiving processor 458, any spatial stream destined for the first communication device 450 is recovered. The symbols on each spatial 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 second communication device 410 on the physical channel.

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.
