本申请涉及通信技术领域,尤其涉及一种数据传输方法及相关装置。
背景技术
终端设备(user equipment,UE)传输上行数据的资源可以基于网络的动态调度,也可以是预配置(configured grant,CG)资源,CG资源是网络预配置的一组周期性出现的上行资源。UE在非激活态下可以进行小数据传输(small data transmission,SDT),包括基于随机接入过程的SDT和基于预配置资源的SDT。
在SDT过程中,第一次上行传输时需要包含无线资源控制(radio resource control,RRC)恢复请求消息,用于对UE进行身份认证,后续的传输需要在网络成功认证UE之后执行。但是对于基于CG资源的SDT过程,UE在CG资源上第一次上行传输的数据还没有被网络成功接收到,UE就可能在下一个CG资源上传输剩余的数据,这样会导致网络还没有对UE进行身份认证,就接收到了后续的数据。

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
以下,对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
本申请实施例中涉及的“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。
以及,除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。例如,第一信息和第二信息,只是为了区分不同的信息,而并不是表示这两种信息的内容、优先级、发送顺序或者重要程度等的不同。
为了便于理解本申请,首先对本申请涉及的概念进行解释。
早期数据传输(early data transmission,EDT):在长期演进(long term evolved,LTE)中,已经引入了EDT,在该过程中,UE可能始终保持在空闲(idle)状态、挂起(suspend)状态和非激活(inactive)状态,完成上行和/或下行小数据包的传输。在配置上,网络会在系统信息块(system information block,SIB)上配置当前网络允许传输的最大传输块(transport block,TB)的大小。UE判断待传输的数据量,如果小于这个允许传输的最大TB的大小,则UE可以发起EDT传输;反之,UE使用正常的连接建立过程,进入连接态传输数据。
参见图1,图1为EDT的流程示意图。如图1所示,在UE发起EDT的小区与最后的服务小区相同的情况下,基站在收到UE发送的连接恢复请求及上行数据后,可以直接将上行数据递交给核心网。
预配置上行资源(preconfigured uplink resource,PUR):针对窄带物联网(narrow band Internet of things,NB-IoT)和增强型机器类型通信(enhanced machine-type communication,eMTC)场景,引入了在空闲态利用PUR进行数据传输的方法。PUR只在当前配置的小区内有效,也就是说当UE检测到小区变化,并在新的小区发起随机接入时,UE需要释放原小区配置的PUR。参见图2,图2为PUR传输的流程示意图。
预配置资源(configured grant,CG):UE传输上行数据的资源可以基于网络的动态调度(通过下行控制信息(downlink control information,DCI)指示),也可以是CG资源,CG资源是网络预配置的一组周期性出现的上行资源。上行CG资源可以分为type1和type 2两种类型。
CG type 1由无线资源控制(radio resource control,RRC)参数配置,包括时域资源、频域资源、解调参考信号(demodulation reference signal,DMRS)、开环功控、调制编码方案(modulation and coding scheme,MCS)、波形、冗余版本、重复次数、调频、混合自动重传请求(hybrid automatic repeat request,HARQ)进程等参数。UE在接收到高层配置后,即可使用配置的CG type 1资源进行上行数据传输,此外不需要额外的激活步骤。
CG type 2同样通过RRC参数配置,但是配置的CG type 2资源的激活通过配置调度无线网络临时标识(configured scheduling radio network temporary identifier,CS-RNTI)加扰的DCI指示,并同时配置包括时域资源、频域资源、DMRS、MCS等传输资源和传输参数。UE在接收到高层配置后,不可使用CG type 2资源,必须等到接收到相应的DCI激活指令和配置信息后,才能进行上行数据传输。
UE根据网络配置,确定CG资源对应的HARQ进程,当UE利用某一个HARQ进程对应的CG资源完成上行数据传输后,启动定时器。在定时器运行期间,UE不可以使用具有相同HARQ进程的CG资源传输新的数据,以避免HARQ缓存(buffer)中的数据被其他数据覆盖。当定时器超时后,指示相应HARQ进程传输的数据已被网络成功接收。
小数据传输(small data transmission,SDT):在第五代移动通信技术(the 5th generation,5G)新空口(new radio,NR)系统中,RRC状态分为三种,分别为RRC空闲态、RRC非激活态和RRC连接态。其中,RRC非激活态是5G系统从节能角度考虑引入的新状态,对于RRC非激活态的UE,无线承载和全部无线资源都会被释放,但是UE侧和基站侧保留UE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UE保持在RRC非激活态。
Release 16之前,处于RRC非激活态的UE不支持数据传输,当上行或下行数据到达时,UE需要恢复连接,待数据传输完成后再释放到非激活态。对于数据量小且传输频率低的UE,这样的传输机制会导致不必要的功耗和信令开销。因此,release 17中提出了RRC非激活态下的SDT技术,包括基于随机接入过程的SDT和基于预配置资源(例如CG type 1)的SDT。
对于基于随机接入过程的SDT(RA-SDT)和基于预配置资源的SDT(CG-SDT)两种方案,在第一次上行传输中都需要包含公共控制信道(common control channel,CCCH)消息,该CCCH消息可以为现有的RRC恢复请求消息。
SDT还支持后续(subsequent)传输,也就是说,UE在完成第一次上行数据传输后,可以继续保持在非激活态传输上行数据或接收下行数据。对于CG-SDT,subsequent传输可以基于网络的动态调度,也可以基于CG。
RRC恢复请求消息中包含非激活态无线网络临时标识(inactive radio network temporary identifier,I-RNTI)、恢复媒体接入控制识别(resume medium access control identify,Resume MAC-I)和恢复原因(Resume cause),其中,I-RNTI为UE标识,用于基站根据I-RNTI找到UE上下文;Resume MAC-I用于基站对UE进行身份认证;Resume cause用于指示UE发起连接请求的原因。
在SDT过程中,第一次上行传输时需要包含RRC恢复请求消息,用于基站确定UE身份,找到UE接入上下文,并对UE的身份进行鉴权。后续的传输需要在网络成功认证UE之后执行。
对于CG-SDT过程,用于第一次上行数据传输的资源为CG,用于后续数据传输的资源既可以为CG,也可以为基于动态调度的资源。UE在CG资源上第一次上行传输的数据还没有被网络成功接收到,UE就可能在下一个CG资源上传 输剩余的数据,这样会导致网络还没有对UE进行身份认证,就接收到了后续的数据。
如上介绍了本申请的背景技术,下面介绍本申请实施例的技术特征。
参见图3,图3为本申请实施例可应用的一种通信系统的示意图。如图3所示,该通信系统包括网络设备301和终端设备302。处于RRC非激活态的终端设备302,在满足第一条件的情况下执行CG-SDT过程。其中,第一条件包括:待传输数据全部来自于允许触发SDT的无线承载、待传输数据量小于或等于网络设备301配置的数据量门限、下行参考信号接收功率(reference signal received power,RSRP)测量结果大于或等于执行SDT的RSRP门限、所选载波及同步信号块(synchronization signal block,SSB)上存在CG资源、存在有效的定时提前(timing advance,TA)和下一跳链计数(next hop chaining count,NCC)等信息。终端设备302在第一CG资源上发送第一上行数据,其中,该第一上行数据包括第一信息,该第一信息用于终端设备302的身份认证。经过第一时长后,终端设备302在第二CG资源上发送第二上行数据。可以看出,终端设备302在第一CG资源上发送第一上行数据,经过第一时长后,再在第二CG资源上发送第二上行数据。第一时长的设置,保证了网络设备301在对终端设备302进行身份认证后,终端设备302才可以发送第二上行数据。避免了在基于CG资源的SDT过程中,网络还没有对UE进行身份认证就接收到后续数据的问题。
