为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
在5G NR系统中,无线资源控制(Radio Resource Control,RRC)状态分为3种,分别为:RRC空闲(RRC_IDLE)态、RRC非激活态或RRC去激活(RRC_INACTIVE)态、RRC连接 (RRC_CONNECTED)态。其中,RRC_INACTIVE态是5G系统从节能角度考虑引入的新状态,对于RRC_INACTIVE态的终端,无线承载和全部无线资源都会被释放,但终端侧和基站侧保留终端接入上下文,以便快速恢复RRC连接,网络通常将数据传输不频繁的终端保持在RRC_INACTIVE态。在一些实施例中,RRC_INACTIVE态的终端可以进行小数据传输(Small Data Transmission,SDT),例如,终端设备可以执行基于随机接入过程(两步随机接入和/或四步随机接入)的上行小数据传输。
在一些实施例中,对于处于RRC_INACTIVE态的终端,在满足以下条件时,触发SDT:
待传输数据来自可以触发SDT的无线承载,例如,信令无线承载(Signaling Radio Bearers,SRB)和/或数据无线承载(Data Radio Bearer,DRB);
待传输数据量小于网络预配置数据量门限;
下行参考信号接收功率(Reference Signal Received Power,RSRP)测量结果大于网络预配置RSRP门限;
存在有效的SDT资源,例如,随机接入SDT(Random Access SDT,RA-SDT)资源和/或配置授权SDT(Configured Grant SDT,CG-SDT)资源。
在一些实施例中,若终端同时被配置了RA-SDT资源和CG-SDT资源,终端优先判断CG-SDT资源是否有效,判断条件包括:
存在有效的定时提前量(Timing Advance,TA),判断方式包括:SDT-TA定时器(SDT-TAT)处于运行状态,和/或,RSRP变化量没有超过预配置门限;
所选载波(正常上行链路(Normal Uplink,NUL)或补充上行链路(Supplementary Uplink,SUL))上存在CG-SDT资源;
所选同步信号块(Synchronization Signal Block,SSB)上存在CG-SDT资源。
具体的,若终端上述条件不能满足,则终端进一步判断RA-SDT资源是否有效,若有效,则发起RA-SDT过程,即终端执行随机接入使用两步随机接入中的第一条消息(Message A,Msg A)中填充(payload)字段或者四步随机接入过程中的第三条消息(Message 3,Msg 3)将小数据发送至网络。否则,发起RRC恢复流程。
在一些实施例中,在SDT过程中,终端在遇到以下事件时,认为SDT失败,并进入RRC空闲(RRC_IDLE)态:
在SDT过程中发生了小区重选;
SDT失败检测定时器(SDT failure detection timer)超时;
无线链路控制(Radio Link Control,RLC)达到最大传输次数,即检测到RLC失败。
为便于更好的理解本申请实施例,对本申请相关的自组织网络(Self-Organizing Network,SON)进行说明。
SON可以根据终端设备上报的信息优化网络参数配置,信令流程可以如图2所示。具体的,网络设备向处于连接态的终端设备发送终端信息请求(UEInformationRequest),UEInformationRequest中包括网络设备需要终端设备上报的信息类型,例如,随机接入报告请求(ra-ReportReq),RLF报告请求(rlf-ReportReq)等。
以随机接入报告请求(ra-ReportReq)为例,如下网络设备向终端设备发送终端信息请求(UEInformationRequest),且随机接入报告请求(ra-ReportReq),当ra-ReportReq为真(true)时,表示网络设备需要终端设备上报随机结果过程相关的信息。终端设备根据网络设备的指示,通过终端信息响应(UEInformationResponse)消息将相应类型的报告反馈给网络。
示例性地,终端信息请求(UEInformationRequest)可以为以下语法元素。
Figure PCTCN2021136812-appb-000001
示例性地,终端信息响应(UEInformationResponse)可以为以下语法元素。
Figure PCTCN2021136812-appb-000002
在一些实施例中,终端设备针对不同的事件,触发记录上述各个类型的报告。以随机接入报告(ra-Report)为例,终端设备在每次成功完成随机接入后,将随机接入过程信息存储在终端设备维护 的随机接入报告参数(VarRA-Report)列表中。当收到网络侧的上报请求时,便将记录的随机接入报告上报给网络设备。
在一些实施例中,随机接入报告的生成条件:终端成功完成随机接入。
随机接入报告可以包括以下信息元素(Information element,IE):
随机接入所在小区标识(Identity,ID);
随机接入的目的:接入相关的(access related)、波束失败恢复(beamFailureRecovery)、同步重配置(reconfigurationWithSync)、上行失步(ulUnsynchronized)、调度请求失败(schedulingRequestFailure)、无可用的物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源(noPUCCHResourceAvailable)、请求其他系统信息(requestForOtherSI);
执行随机接入的带宽部分(Band Width Part,BWP)的频率位置、子载波信息、随机接入机会(Random Access Occasion,RO)频分复用(frequency-division multiplexing,FDM)个数信息;
具体随机接入情况:SSB索引、在每一个SSB下随机接入尝试的次数、随机接入尝试是否遇到碰撞(collision)、目标SSB是否高于SSB的RSRP阈值(rsrp-ThresholdSSB)。
在一些实施例中,当使用随机接入传输SDT时,网络设备可以为SDT配置与为其他原因执行的随机接入不同的竞争的随机接入过程(Contention Based Random Access,CBRA)随机接入资源,如序列码、随机接入时频域资源等。
为便于更好的理解本申请实施例,对本申请所解决的问题进行说明。
当前随机接入报告无法准确告知网络终端执行随机接入是否是因为发送小数据包,如果出现终端执行随机接入发送小数据包总是出现碰撞问题,网络无法对应的对用于小数据包传输的随机接入资源分配进行调整。
基于上述问题,本申请提出了一种小数据传输的方案,终端设备可以在随机接入报告中指示执行随机接入的目的为小数据传输,从而,网络设备可以基于随机接入报告确定是否对用于小数据传输的随机接入资源进行优化调整,从而优化小数据传输。
以下通过具体实施例详述本申请的技术方案。
图3是根据本申请实施例的无线通信的方法200的示意性流程图,如图3所示,该无线通信的方法200可以包括如下内容中的至少部分内容:
S210,终端设备向网络设备发送随机接入报告;其中,该随机接入报告包括第一指示信息,该第一指示信息用于指示执行随机接入的目的为SDT;
S220,该网络设备接收该终端设备发送的该随机接入报告。
在本申请实施例中,终端设备上报随机接入报告,且随机接入报告中包括的第一指示信息用于指示执行随机接入的目的为SDT,从而,网络设备可以基于随机接入报告确定是否对用于小数据传输的随机接入资源进行优化调整,从而优化小数据传输。
在一些实施例中,终端设备可以主动向网络设备发送随机接入报告。
在一些实施例中,终端设备可以在网络设备的请求下向网络设备发送随机接入报告。例如,可以对应如图2所示的自组织网络(SON)。
在一些实施例中,该第一指示信息为该随机接入报告中的随机接入目的信息元素(IE)中的一个字段。当然,该第一指示信息也可以为该随机接入报告中的其他信息元素(IE)中的一个字段。本申请对此并不限定。
在一些实施例中,该随机接入报告还包括第二指示信息;其中,该第二指示信息用于指示针对SDT的随机接入中随机接入冲突解决失败的次数大于或等于第一门限值,或者,该第二指示信息用于指示针对SDT的随机接入中发生碰撞的次数大于或等于第二门限值。
在一些实施例中,该第一门限值可以由协议约定,或者,该第一门限值可以由网络设备配置。例如,该第一门限值为3,或4,或5,或6,或7。
在一些实施例中,该第二门限值可以由协议约定,或者,该第二门限值可以由网络设备配置。例如,该第二门限值为3,或4,或5,或6,或7。

具体例如,网络设备为终端设备在每个RO上配置了2个随机接入前导码用于随机接入;在终端设备执行随机接入发送SDT至网络设备的过程中,众多终端在成功将小数据包发送至网络设备前经历了起码六次随机接入冲突解决失败(如Msg A或Msg3发送发生碰撞);终端设备将随机接入情况存储在随机接入报告中发送至网络设备;网络设备根据终端设备在随机接入报告中反映的SDT随机接入Msg A或Msg3碰撞情况,适当的提高了用于SDT发送的随机接入前导码的数量,比如从2提高到5。
因此,在本申请实施例中,终端设备上报随机接入报告,且随机接入报告中包括的第一指示信息用于指示执行随机接入的目的为SDT,从而,网络设备可以基于随机接入报告确定是否对用于小数据传输的随机接入资源进行调整,从而优化小数据传输。
