Description
本发明涉及无线通信技术领域,更具体地,本发明涉及由用户设备执行的方法以及相应的用户设备。
随着5G的标准化和逐步商用,其应用场景也越来越多元化。首先,对于工业无线传感器场景,各种传感器种类繁多、用途各异。这些传感器中,一部分要求高可靠低时延或者大带宽,一部分要求超低成本和超长的电池使用寿命,而还有一部分的要求则介于前两者之间。这部分设备可以被认为是一些降低能力的NR设备。其次,随着智慧城市的规划和发展,视频监控和信息采集被普遍使用,用于这类应用的无线设备也有上面提到的降低能力的NR设备的类似特点。最后,众多的可穿戴设备,如智能手表、智能手环、健康状况监控仪等,也同样具有降低能力的NR设备的特点。对于这一类降低能力的NR设备,原有的标准并不能够很好的支撑其达到最佳的性能要求。
基于上述原因,2019年12月,在第三代合作伙伴计划(3rd Generation Partnership Project:3GPP)RAN#86次全会上,针对版本17的降低能力NR设备的研究项目(参见非专利文献:RP-193238New SID on Study on Support of reduced capability NR devices),并获批准。该研究项目将项目的适用场景确定为工业无线传感器,视频监控和可穿戴设备。该研究项目的目标之一是对降低能力的NR设备的功耗节省以及电池寿命增强的研究,包括减少下行控制信道(PDCCH)的监听,RRC非激活状态或空闲状态下的eDRX(扩展的不连续接收),对于静止设备的无线资源管理(RRM)测量的放松。该研究目标主要针对工业无线传感器和可穿戴设备。
NR非激活态下的小数据传输是3GPP在版本17的一个工作项目,该项目是为了缩短传输时延,节约信令开销。进入RRC非激活状态的UE可 以在配置的用于小数据传输的上行指配中发送携带数据的传输块(Transport Block)。还可以在随机接入的过程中,在消息三或者消息A中发送携带用户数据的传输块。这两种方式都可以被称为小数据传输。小数据传输可以使得UE不必恢复到连接态,就可以在非激活态下实现数据的传输。
UE为了节能而采用非激活态的eDRX,同时该设备有周期的小数据发送而需要在非激活态下进行小数据传输。本发明讨论这种场景下***消息更新的相关问题。
发明内容

本发明中,网络、基站和RAN可互换使用,所述网络可以是长期演进LET网络、新无线访问技术(New RAT,NR)网络、增强的长期演进eLTE网络,也可以是3GPP后续演进版本中定义的其他网络。
本发明中,用户设备UE可以指背景技术中所述的降低能力的NR设备,也可以指其他类型的NR设备或者LTE设备。
以下,对本发明的相关技术给出说明。
NR中***消息修改周期是周期性的时间,包含若干个SFN,由***消息配置。基站如果要改变***消息,可以在某个修改周期内指示UE***消息改变,在下一个修改周期开始广播改变了的***消息。***消息改变指示包含在Short Message(短消息)中,Short Message可以在每个PO下发。Short Message是DCI格式1_0中用于指示***消息相关信息的一些字段,用P-RNTI加扰并在PDCCH上传输的。在RRC_IDLE或者RRC_INACTIVE状态下,UE在每个DRX cycle中监听属于自己的PO来获取***消息改变指示,UE自己的PO是根据UE_ID计算得到的所有PO中的一个子集。在RRC_CONNECTED状态下,如果UE被提供了公共搜索空间,而该公共搜索空间在激活的BWP上包含pagingSearchSpace,searchSpaceSIB1和searchSpaceOtherSystemInformation配置,则UE在每个修改周期至少监听一次任意PO来获取***消息改变指示。如果UE接收到了携带有***消息改变指示的Short Message,则UE在下一个修改周期的开始应用获取***消息的流程,来获取更新的***消息。
LTE中处于RRC_IDLE的UE可以被配置eDRX,即更长的不连续接收,从而节省功耗。对于配置了eDRX周期的UE,根据eDRX***消息获取周期来更新***消息。eDRX***消息获取周期为若干个H-SFN,并且该周期边界为固定的H-SFN号。配置了eDRX周期的UE可以同时被配置周期的PTW,PTW是eDRX周期内的一段寻呼监听时间,在每个eDRX周 期内,UE只需要监听落在PTW之内的PO。如果在一个eDRX***消息获取周期内***消息发生了改变,则基站可以在寻呼消息中或者DCI中携带eDRX***消息改变指示。如果UE的eDRX周期长于***消息修改周期,则UE通过监听PO获取eDRX***消息改变指示,如果收到了该指示,则在下一个eDRX***消息获取周期的开始应用获取***消息的流程,来获取更新了的***消息。为了避免使用未更新的***消息造成接入失败,如果UE的eDRX周期长于***消息修改周期,并且距离UE上一次校验***消息有效性经过了至少一个***消息修改周期边界,则UE需要在建立或者恢复RRC连接前校验***消息的有效性,如果UE保存的***消息已经无效则执行***消息获取流程。
NR中引入RRC_INACTIVE状态eDRX后,一种可能性是沿用LTE中RRC_IDLE态eDRX下的***消息更新处理机制,LTE中的处理机制如上所述。
根据降低能力的NR设备研究,降低能力的NR设备可以在配置了RRC_INACTIVE eDRX的情况下,在RRC_INACTIVE态下进行小数据传输。当UE处于RRC_INACTIVE状态时,UE的上层,例如非接入层,可以请求UE恢复RRC连接。如果UE支持并且决定采用小数据传输的方式,那么UE可以在配置的用于小数据传输的上行指配或者随机接入过程中发送一个MAC PDU,在该MAC PDU中携带RRC连接恢复请求,以及用户的数据。这样的RRC连接恢复过程可以被称为是用于小数据传输的RRC连接恢复过程(或者被称为是小数据传输触发的RRC连接恢复过程)。在小数据传输触发的RRC连接恢复过程后,如果UE还有更多的小数据需要发送,可以不必进入连接态,而通过在动态获取的资源或者配置的用于小数传输的上行指配上发送后续的这些小数据。
在RRC_INACTIVE下的小数据传输过程中,可能会发生***消息改变,如果UE只在发起小数据传输的RRC连接恢复前校验***消息有效性而触发可能的***消息获取,则在小数据传输过程中根据eDRX的***消息更新机制可能会无法及时得到***消息改变指示,而无法及时获取更新了的***消息。这会影响小数据传输,尤其是在UE发送了第一个小数据后,还有更多的小数据传输的场景下。
以下,详细描述本发明对于上述问题的若干实施例。
实施例1
图1是示出了根据本发明的实施例1的由用户设备执行的方法的流程图。
如图1所示,在步骤101,如果eDRX的配置情况满足要求,UE在RRC_INACTIVE状态小数据传输过程中,UE根据DRX周期监听自己的PO获取Short Message(短消息)。
其中,eDRX的配置情况满足要求,可以包括但不限于如下一种可能:
1)配置了RRC_INACTIVE eDRX参数(如eDRX周期,偏移等);
2)配置的RRC_INACTIVE eDRX周期大于***消息修改周期。
其中,小数据传输过程可以包括但不限于如下的一种可能:
1)从UE发起小数据传输的RRC连接恢复开始,到接收到基站的消息或者指示结束小数据传输;
2)从UE发起小数据传输的RRC连接恢复开始,到UE完成所有的小数据传输;
3)从UE发起小数据传输的RRC连接恢复开始,到UE不再等待下行的确认或者响应;
4)从UE发起小数据传输的RRC连接恢复开始,到释放配置的用于小数据传输的上行指配;
5)UE发送小数据以及接收小数据确认和响应消息的过程。
在步骤103,当UE获取的Short Message中携带有***消息改变指示,即***消息改变第一指示,则UE在下一个***消息修改周期开始位置执行获取***消息流程。
可选地,如果eDRX的配置情况满足要求(如上所述),UE在RRC_INACTIVE状态小数据传输过程结束,或者UE在RRC_INACTIVE状态但未处在小数据传输过程,则UE根据eDRX周期在PTW内监听自己PO。如果UE获取到Short Message,并且其中携带了eDRX***消息改变指示(***消息改变第二指示),UE在下一个eDRX***消息获取周期边界执行获取***消息流程。
可选地,如果eDRX的配置情况不能满足要求(即未配置eDRX,或者 eDRX周期没有长于修改周期,或者只配置了DRX),则UE根据DRX周期监听自己的PO。如果UE获取到Short Message,并且其中携带了***消息改变指示,UE在下一个***消息修改周期开始位置执行获取***消息流程。
实施例2
可选地,如果eDRX的配置情况满足要求,UE在RRC_INACTIVE状态下小数据传输过程中,如果UE被提供了公共搜索空间,而该公共搜索空间在激活的BWP上包含pagingSearchSpace,searchSpaceSIB1和searchSpaceOtherSystemInformation配置,则UE在每个***消息修改周期至少监听一次任意PO来获取***消息改变指示(或者获取Short Message),即和RRC_CONNECTED状态下获取***消息改变指示(或者获取Short Message)的处理相同。
其中,eDRX的配置情况满足要求的可能性如实施例1所述。
其中,小数据传输过程可以包括但不限于的情况如实施例1所述。
当UE获取的Short Message中携带有***消息改变指示,即***消息改变第一指示,则UE在下一个***消息修改周期开始位置执行获取***消息流程。
可选地,如果eDRX的配置情况满足要求,UE在RRC_INACTIVE状态下小数据传输过程中,在每个***消息修改周期至少监听一次任意PO来获取***消息改变指示(或者获取Short Message),即和RRC_CONNECTED状态下获取***消息改变指示(或者获取Short Message)的处理相同。
可选地,如果eDRX的配置情况不能满足要求(即未配置eDRX,或者eDRX周期没有长于修改周期,或者只配置了DRX),UE在RRC_INACTIVE状态下小数据传输过程中,如果UE被提供了公共搜索空间,而该公共搜索空间在激活的BWP上包含pagingSearchSpace,searchSpaceSIB1和searchSpaceOtherSystemInformation配置,则UE在每个***消息修改周期至少监听一次任意PO来获取***消息改变指示(或者获取Short Message),即和RRC_CONNECTED状态下获取***消息改变指示(或者获取Short Message)的处理相同。
可选地,UE在RRC_INACTIVE状态下小数据传输过程中,如果UE被提供了公共搜索空间,而该公共搜索空间在激活的BWP上包含pagingSearchSpace,searchSpaceSIB1和searchSpaceOtherSystemInformation配置,则UE在每个***消息修改周期至少监听一次任意PO来获取***消息改变指示(或者获取Short Message),即和RRC_CONNECTED状态下获取***消息改变指示(或者获取Short Message)的处理相同。
可选地,UE在RRC_INACTIVE状态下小数据传输过程中,在每个***消息修改周期至少监听一次任意PO来获取***消息改变指示(或者获取Short Message),即和RRC_CONNECTED状态下获取***消息改变指示(或者获取Short Message)的处理相同。
可选地,如果eDRX的配置情况不能满足要求(即未配置eDRX,或者eDRX周期没有长于修改周期,或者只配置了DRX),UE在RRC_INACTIVE状态下小数据传输过程中,在每个***消息修改周期至少监听一次任意PO来获取***消息改变指示(或者获取Short Message),即和RRC_CONNECTED状态下获取***消息改变指示(或者获取Short Message)的处理相同。
实施例3
UE在RRC_INACTIVE状态下小数据传输过程中(小数传输过程的可能性如实施例1中说明),UE收到基站发送的***消息改变第三指示,在下一个***消息修改周期执行获取***消息流程。
其中,***消息改变第三指示可以包括如下的一种可能:
1)***消息改变第三指示为一个新的MAC CE,例如***消息改变MAC CE;
2)***消息改变第三指示为一个新增MAC CE(例如***消息改变MAC CE)中的一个或若干个比特位;
3)***消息改变第三指示为一个已有MAC CE中的一个或若干个新增比特位;
4)***消息改变第三指示为一个新的DCI中的一个或若干个比特位;
5)***消息改变第三指示为一个已有DCI中的一个或若干个新增比特位。
如上的MAC CE或者DCI可以是用C-RNTI加扰的。
实施例4
UE在RRC_INACTIVE状态下小数据传输过程中(小数传输过程的可能性如实施例1中说明),UE监听PDCCH的处理和配置了DRX的UE在RRC_CONNECTED下的监听PDCCH的处理相同。
