Abstract
本申请实施例提供了一种无线通信方法、终端设备和网络设备,该方法包括:终端设备接收第一业务的存活期相关参数,终端设备根据存活期相关参数对业务传输进行处理。从而可以提高通信服务的传输成功率。
Description
本申请实施例涉及通信领域,并且更具体地,涉及无线通信方法、终端设备和网络设备。
版本(Release,R)17高可靠低时延通信(Ultra Reliable and Low Latency Communications,URLLC)项目要求无线接入网(Radio Access Network,RAN)基于应用或业务的存活期(survivial time)进行增强。
目前业务的存活期的定义是:存活期被应用功能(Application Function,AF)以时间为单位定义,其中这里的时间可以是以突发周期(即业务周期)或者最大连续消息传输错误(即失败)的次数来衡量,一个消息指的是在一个独立突发(即突发周期)包括的一个数据包或者架构,或者,一组数据包或者架构,所谓消息传输错误指的是该消息不能满足分组延迟预算(Packet Delay Budget,PDB)的要求。也就是说,对一个应用或业务来说,当存活期以业务周期表征,且该存活期等于一个业务周期时,当前一个数据包传输失败后,该数据包的后一个包一定要正确传输。否则,通信业务传输出错。或者说,对一个应用或业务来说,当存活期以连续传输错误的数据包表征,且存活期等于X个连续传输错误的数据包,当连续X个数据包连续传输错误,则通信业务传输出错。所以,当有连续X-1个包传输失败后,则第X个数据包一定要正确传输。综上,当业务不满足存活期的要求时,会造成通信服务的失败。

可选地,上述调度信息是下行链路反馈指示(Downlink Feedback Indicator,DFI),其用于指示是否进行重传,NACK代表要重传,ACK代表传输成功。因此,当终端设备根据网络设备的DFI信息确定是NACK时,可以计算数据包的发送时间以及调度信息的时间差,以得到数据包的传输时延。

需要说明的是,这种传输状态相对于上述14项传输状态,这里的传输状态相当于“因”,终端设备将这里的传输状态发送给网络设备后,网络设备即可得到如上述14项传输状态,即得到“果”。
可选地,无论是这里的传输状态还是上述14项传输状态,其还包括以下至少一项:DRB标识,QoS flow标识、TSN steam标识、PDU session标识。
可选地,无论是这里的传输状态还是上述14项传输状态,其是以下任一级别的传输状态:数据包级别、终端设备级别、DRB级别、QoS flow级别、PDU session级别、TSN steam级数据包级别。
其中,若传输状态是终端设备级别、DRB级别、QoS flow级别、PDU session级别或TSN steam 级数据包级别的,那么上述的数据包的数据包的发送时间、终端设备计算的数据包的传输时延或累计传输时延、数据包的反馈信息可以被理解为是针对多个数据包的统计信息,如平均值等。
