本公开涉及通信应用的技术领域,尤其涉及一种数据传输方法、终端及网络设备。
背景技术
在长期演进(Long Term Evolution,LTE)或5G新空口(New RAT,NR)系统中,上下行数据的传输是通过混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)实现的。如图1所示,用户设备或终端(User Equipment,UE)可以有多个媒体接入控制(Medium Access Control,MAC)实体(如,主小区组(Master Cell Group,MCG)MAC和辅小区组(Secondary Cell Group,SCG)MAC),每个MAC实体有自己独立的HARQ实体(Entity)。每个HARQ实体用于控制1个小区或频点(如,图1中的单元载波CC1)的数据的收发,即1个CC的数据的发送和重传都是通过相同的HARQ实体实现的。每个HARQ实体有多个HARQ进程(process),不同的数据通过不同的HARQ进程进行收发。其中,每个CC上的HARQ process的数量由HARQ回程时间(Round Trip Time,RTT)决定(即,从数据发送到接收到对于该数据的反馈的时间。如回程时间是8毫秒,每个数据发送时间为1毫秒,则为了在每个时间点都能够发送数据,HARQ process的数量为8)。其中MAC实体和上层实体间的数据接口为逻辑信道(Logical Channel,LCH),如图1中的LCH1,多个逻辑信道的数据可以通过复用(即,multiplexing)功能,作为同一个MAC协议数据单元(Protocol Data Unit,PDU)在HARQ process中发送。
5G(5 Generation,第五代)移动通信系统中,为达到下行链路传输速率20Gbps,上行链路传输速率10Gbps的目标,高频通信和大规模天线技术将 会被引入。高频通信可提供更宽的系统带宽,天线尺寸也可以更小,更加有利于大规模天线在基站和UE中部署。基站侧采用Multi-beam(多波束)或Multi-TRP Transmission Point(多收发节点)进行数据发送和接收,UE侧Multi-beam或Multi-TRP Transmission Point的发送和接收将会广泛应用。
但当采用多个不同的波束或传输节点对UE进行数据收发的时候,采用什么样的HARQ传输方式尚未有明确的方法。
