Description

一种无线通信中的方法和装置 技术领域
本发明涉及无线通信系统中的传输方案,特别是涉及上行传输的方法和装置。
背景技术
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的性能需求,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技术(NR,New Radio)进行研究。
在现有的蜂窝无线通信系统中(比如LTE,Long Term Evolution,长时演进),上下行的数据传输都是基于中心调度的,即每一个基站到用户设备(UE)的下行传输所占用的无线资源和调制编码方式都是由基站分配的,每一个用户设备到基站的上行传输所占用的无线资源和调制编码方式也是由基站事先分配的,这些上下行的调度信息承载在DCI(Downlink Control Information,下行控制信息)中。这种通过中心(基站)分配资源的上下行传输方式可以统称为基于授予(Grant-based)的上下行传输。
在下一代无线蜂窝网络中(比如5G NR,LTE的进一步演进,NB-IoT(Narrow Band Internet of Things,窄带物理网)的进一步演进),仅仅支持基于授予的数据传输无法满足越来越多样化的应用需求。特别是对于上行传输,在对低延时或者对容量有很高要求的场景中,比如URLLC(Ultra Reliable Low Latency Communication,超可靠超低延时通信)对延时要求非常严格,mMTC(massive Machine Type Communication,大规模机器类通信)或NB-IoT或eMTC(enhanced Machine Type Communication)的应用场景对系统容量要求很高,基于授予的方式由于调度延时与传输发起的头开销的限制无法满足场景的需求。因此,与基于授予的方式相对的,上行的传输可以通过一种非授予(Grant-free)的方式完成。非授予的上行传输不需要在开始上行传 输之前由基站动态地分配传输所占用的无线资源和/或调制编码方式,因而可以降低传输时和发起传输所需的头开销。
发明内容
在非授予的上行传输的过程中,由于缺乏集中的动态调度与资源协调,有可能发生碰撞。当非授予的上行传输中也包括前导(Preamble)传输的时候,前导的传输也有可能发生碰撞。但是由于前导一般由互相之间具有很低相关性的序列生成,即使发生碰撞,但只要前导到达接收端的时间不同,接收机还是可以区分出来自于不同的用户设备的前导的传输,这个时候如果相关联的非授予的数据的传输仍然碰撞,就有可能会导致最终的上行发送无法成功被接收与解码。
另一方面,即使非授予的上行传输中不包括前导传输,但是存在多个接收端的时候(比如多个TRP),也有可能会出现上行传输被非目标接收者接收到的情况,造成链路性能下降或者虚警,同时还有可能增加接收机的复杂性。
针对上述的基于非授予的上行传输中由于碰撞导致性能下降的问题,本发明提供了解决方案。该方案通过对上行传输的无线资源针对上行的同步时间进行区分,达到减少碰撞和/或降低接收机复杂性的目的。需要说明的是,在不冲突的情况下,本申请的UE(User Equipment,用户设备)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。进一步的,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。
