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，尤其涉及随机接入的传输方法和装置。The present application relates to transmission methods and devices in wireless communication systems, and in particular to random access transmission methods and devices.
背景技术Background technique
随机接入(Random Access，RA)是3GPP(the 3rd Generation Partnership Project，第三代合作伙伴项目)系统的一个关键技术，用户设备(User Equipment，UE)发起随机接入过程时，通过随机接入资源选择过程确定一个SSB(Synchronization Signal Block，同步信号块)或者CSI-RS(CSI(Channel State Information，信道状态信息)Reference Signal，CSI参考信号)并确定一个随机接入前导(Random Access Preamble)，根据一个SSB或者CSI-RS确定随机接入时机(Occasion)，根据被确定的随机接入时机发送随机接入前导。Random Access (RA) is a key technology of the 3GPP (the 3rd Generation Partnership Project) system. When the user equipment (User Equipment, UE) initiates the random access process, it uses random access The resource selection process determines an SSB (Synchronization Signal Block, synchronization signal block) or CSI-RS (CSI (Channel State Information, channel state information) Reference Signal, CSI reference signal) and determines a random access preamble (Random Access Preamble), The random access opportunity (Occasion) is determined based on an SSB or CSI-RS, and the random access preamble is sent based on the determined random access opportunity.
发明内容Contents of the invention
现有技术中，UE执行随机接入资源选择过程之前，先确定一组随机接入资源。如果关联到一个特征的一组随机接入资源被选择，随机接入前导被用于指示这个特征。由于关联到一个特征的一组随机接入资源被用于指示这个特征，为了避免混淆，如果关联到一个特征的一组随机接入资源被使用的条件被满足，使用关联到这个特征的一组随机接入资源，如果关联到任一特征的一组随机接入资源被使用的条件不被满足，使用不关联到任一特征的一组随机接入资源。由于UE不能随意选择一组随机接入资源，导致随机接入资源的使用不够灵活。在一些场景下，关联到一个特征的一组随机接入资源能够被用于指示另一个特征的部分特征，支持针对另一个特征的随机接入过程选择这组随机接入资源能够提高随机接入资源的使用率，并且，随机接入前导能够指示另一个特征的部分特征，给基站提供更多的信息。如果UE能够支持多组随机接入资源，如何在多组随机接入资源中确定随机接入前导需要进行研究。In the existing technology, before performing the random access resource selection process, the UE first determines a set of random access resources. If a set of random access resources associated with a characteristic is selected, the random access preamble is used to indicate this characteristic. Since a set of random access resources associated with a feature is used to indicate that feature, to avoid confusion, if the conditions for a set of random access resources associated with a feature to be used are met, use a set of random access resources associated with this feature. Random access resources, if the conditions for using a set of random access resources associated with any feature are not met, use a set of random access resources not associated with any feature. Since the UE cannot select a set of random access resources at will, the use of random access resources is not flexible enough. In some scenarios, a set of random access resources associated with one feature can be used to indicate part of the features of another feature. Supporting the selection of this set of random access resources for the random access process of another feature can improve random access. Resource usage, and the random access preamble can indicate part of another feature, providing more information to the base station. If the UE can support multiple sets of random access resources, how to determine the random access preamble in multiple sets of random access resources needs to be studied.
针对上述问题，本申请提供了一种随机接入的解决方案。针对上述问题描述中，采用NR系统作为一个例子；本申请也同样适用于例如LTE系统的场景；进一步的，虽然本申请针对RRC(Radio Resource Control，无线资源控制)不活跃状态的MT-SDT(Small Packet Transmission，小数据包传输)给出了具体的实施方式，但本申请也能被用于例如RRC不活跃状态的多播MBS(Multicast/Broadcast Service，多播/广播服务)的场景，取得类似RRC不活跃状态的MT-SDT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 response to the above problems, this application provides a random access solution.

FIG. 3 shows the radio protocol architecture for the control plane 300 with 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. The L1 layer will be called PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301, including MAC (Medium Access Control, media access control) sublayer 302, RLC (Radio Link Control, wireless link layer control protocol) sublayer 303 and PDCP (Packet Data Convergence Protocol, packet data convergence protocol) sublayer 304. PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security by encrypting data packets, and provides cross-location 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, Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (eg, resource blocks) in a cell. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (ie, radio bearers) and configuring lower layers using RRC signaling. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture in the user plane 350 is for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, and the PDCP sublayer 354 in the L2 layer 355.
