Description

一种支持多载波通信的用户设备、基站中的方法和设备 技术领域
本发明涉及无线通信系统中的无线信号的传输方案，特别是涉及支持多载波通信的方法和装置。
背景技术
传统的基于数字调制方式的无线通信系统，例如3GPP(3rd Generation Partner Project，第三代合作伙伴项目)蜂窝系统中，下行及上行无线信号的发送均基于基站的调度，而调度的相关控制信息是通过DCI(Downlink Control Information，下行控制信息)发送给UE的。新一代的无线接入技术(NR，New Radio access technologies)目前已在3GPP中讨论。其中，一个重要的应用场景就是URLLC(Ultra-Reliable and Low Latency Communications，超高可靠性和低延迟通信)。另外一个重要的场景就是高频载波下，通过大尺度(Massive)MIMO的波束赋型(Beam Forming)，形成较窄的波束指向一个特定方向来提高通信质量，以对抗高频下较为严重的路径损耗。除此之外，通过多个DCI(Downlink Control Information，下行控制信息)来调度同一块数据的传输，在Rel-14的降低延迟相关的Study Item(研究课题)中已被引入，且在最新的NR讨论中，也被提及并讨论。
发明内容
NR系统中，UE将会面对针对不同BLER(Block Error Rate，块误码率)要求以及不同延迟需求的业务，并需要在不同频带下同时进行传输。由于传输所发生的载波的物理特性不同，会导致单位距离下不同的路径损耗，载波频率越高则路径损耗越严重。针对一个DCI中不同域(Field)的特点，针对一次数据传输的Multi-DCI已在3GPP中被讨论。一种直观的做法，就是将Multi-DCI均放在一个载波上进行传输。然而，当此种方式在高频Massive-MIMO下应用于URLLC时，因为路损过大，同时满足高传输鲁棒性和低延迟将会别的较为困难。
针对上述问题，本发明提供了解决方案。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。例如，本申请的UE中的实施例和实施例中的特征可以应用到基站中，反之亦然。
本发明公开了一种支持多载波通信的UE中的方法，其中，包括：

实施例10
实施例10示出了根据本申请的一个用户平面和控制平面的无线协议架构的实施例的示意图，如附图10所示。
附图10是说明用于用户平面和控制平面的无线电协议架构的实施例的示意图，图10用三个层展示用于用户设备(UE)和基站设备(gNB或eNB)的无线电协议架构：层1、层2和层3。层1(L1层)是最低层且实施各种PHY(物理层)信号处理功能。L1层在本文将称为PHY301。层2(L2层)305在PHY301之上，且负责通过PHY301在UE与gNB之间的链路。在用户平面中，L2层305包括MAC(Medium Access Control，媒体接入控制)子层302、RLC(Radio Link Control，无线链路层控制协议)子层303和PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)子层304，这些子层终止于网络侧上的gNB处。虽然未图示，但UE可具有在L2层305之上的若干上部层，包括终止于网络侧上的P-GW处的网络层(例如，IP层)和终止于连接的另一端(例如，远端UE、服务器等等)处的应用层。PDCP子层304提供不同无线电承载与逻辑信道之间的多路复用。PDCP子层304还提供用于上部层数据包的标头压缩以减少无线电发射开销，通过加密数据包而提供安全性，以及提供gNB之间的对UE的越区移交支持。RLC子层303提供上部层数据包的分段和重组装，丢失数据包的重新发射以及数据包的重排序以补偿由于HARQ造成的无序接收。MAC子层302提供逻辑与输送信道之间的多路复用。MAC子层302还负责在UE之间分配一个小区中的各种无线电资源(例如，资源块)。MAC子层302还负责HARQ操作。在控制平面中，用于UE和gNB的无线电协议架构对于物理层301和L2层305来说大体上相同，但没有用于控制平面的标头压缩功能。控制平面还包括层3(L3层)中的RRC(Radio Resource Control，无线电资源控制)子层306。RRC子层306负责获得无线电资源(即，无线电承载)且使用gNB与UE之间的RRC信令来配置下部层。
