技术领域
本申请涉及通信技术领域,尤其涉及一种用于无线通信的方法及装置。
背景技术
在无线通信网络的信息反馈机制中,接收节点在成功接收到或未成功接收到数据时,可以向发送该数据的发送节点反馈针对该数据的接收状态(例如成功接收或未成功接收),以协助发送节点判断是否要重传该数据。上述信息反馈机制的主要问题是,接收节点仅能反馈针对编码数据或编码数据组的接收状态,从而无法为发送节点提供更加丰富的反馈信息,从而可能导致数据传输效率的下降。因此,如何设计更加灵活的信息反馈方式以提高数据传输效率,成为亟需解决的问题。

具体实施方式
本申请实施例提供的用于无线通信的方法及装置可以应用于通信系统中。如图1示出了一种通信系统结构示意图。该通信系统中包括一个或多个网络设备(清楚起见,图中示出网络设备10和网络设备20),以及与该一个或多个网络设备通信的一个或多个终端设备。图1中所示终端设备11和终端设备12与网络设备10通信,所示终端设备21和终端设备22与网络设备20通信。可以理解的是,网络设备和终端设备也可以被称为通信设备。
本发明实施例描述的技术可用于各种通信系统,例如2G,3G,4G,4.5G,5G通信系统,多种通信系统融合的系统,或者未来演进网络。例如长期演进(long term evolution,LTE)系统,新空口(new radio,NR)系统,无线保真(wireless-fidelity,WiFi)系统,以及第三代合作伙伴计划(3rd generation partnership project,3GPP)相关的蜂窝系统等,以及其他此类通信系统。
图2示出了通信系统的一种可能的架构举例示意图,如图2所示无线接入网(radio access network,RAN)中的网络设备是集中单元(centralized unit,CU)和分布单元(distributed unit,DU)分离架构的基站(如gNodeB或gNB)。RAN可以与核心网相连(例如可以是LTE的核心网,也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连,例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如分组数据汇聚层协议(packet data convergence protocol,PDCP)层及无线资源控制(radio resource control,RRC)层的功能设置在CU,而无线链路控制(radio link control,RLC),媒体接入控制(media access control,MAC)层,物理(physical)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例,也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如,CU或DU还可以划分为具有协议层的部分处理功能。在一设计中,将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中,还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分,将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。图2所示的网络架构可以应用于5G通信系统,其也可以与LTE系统共享一个或多个部件或资源。在另一种设计中,CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置,也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能,也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现,也可以进一步将控制面(CP)和用户面(UP)分离,即CU的控制面(CU-CP)和用户面(CU-UP)可以由不同的功能实体来实现,所述CU-CP和CU-UP可以与DU相耦合,共同完成基站的功能。
可以理解的是,本申请中提供的实施例也适用于CU和DU不分离的架构。

终端是一种具有无线收发功能的设备,可以部署在陆地上,包括室内或室外、手持、穿戴或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴终端设备等等。本申请的实施例对应用场景不做限定。终端有时也可以称为终端设备、用户设备(user equipment,UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、终端设备、无线通信设备、UE代理或UE装置等。终端也可以是固定的或者移动的。
在无线通信网络的信息反馈机制中,接收节点(例如终端)在成功接收到或未成功接收到数据时,可以向发送该数据的发送节点(例如网络设备、或另一个终端)反馈针对该数据的接收状态(例如成功接收或未成功接收),以协助发送节点判断是否要重传该数据。上述信息反馈机制的主要问题是,接收节点仅能反馈针对编码数据或编码数据组的接收状态,从而无法为发送节点提供更加丰富的反馈信息,从而可能导致数据传输效率的下降。因此,如何设计更加灵活的信息反馈方式以提高数据传输效率,成为亟需解决的问题。
本申请实施例提供的方法中,接收数据的接收节点可以反馈对编码数据或编码数据组中被编码数据的接收状态,因此可以为发送编码数据或编码数据组的发送节点提供更丰富的反馈信息,使得发送节点在接下来的数据发送中能够更加合理的组织发送的数据,减少不必要的重传,从而提高数据的传输效率。
下面以具体实施例结合附图对本申请的技术方案进行详细说明。下述实施例和实施方式可以相互结合,对于相同或相似的概念或过程可能在某些实施例不再赘述。应理解,本申请中所解释的功能可以通过独立硬件电路、使用结合处理器/微处理器或通用计算机而运行的软件、使用专用集成电路,和/或使用一个或多个数字信号处理器来实现。当本申请描述为方法时,其还可以在计算机处理器和被耦合到处理器的存储器中实现。
