Description

数据传输方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输方法及装置。
背景技术
第五代移动通信技术(The Fifth-Generation mobile communications，5G)新无线(New Radio，NR)系统中，在用户设备(User Equipment，UE)处于无线资源控制(Radio Resource Control，RRC)空闲态(idle)或者非激活态(inactive)时，若UE需要发送上行数据和/或接收下行数据，UE需要从空闲态或者非激活态切换至连接态(connected)。目前，存在一种处于RRC空闲态或者非激活态的UE传输数据的方式。网络设备给UE配置专用的上行预配置资源(Preconfigure Uplink resource，PUR)以及对应的下行搜索空间窗(PUR Search space window，PUR SS Window)。从而，UE可以利用PUR发送上行数据，并利用PUR SS Window接收下行数据。
然而，在NR系统中，处于RRC空闲态或者非激活态的UE传输数据需要下行同步以及AGC(自动增益控制)调整。现有技术中，UE常常利用同步信号块(SS/PBCH block，SSB)来完成下行同步和AGC调整。但是，当SSB位于PUR之前，且SSB和PUR在时域上的间隔很大时，UE的能耗很大，用户体验差。
因此，如何降低UE在数据传输过程中的能耗是目前亟需解决的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实 施例，都属于本发明保护的范围。
需要说明的是，本申请的说明书和权利要求书中及上述附图中的属于“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述以外的顺序实施。此外，术语“包括”及其任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或服务器不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请中实施例中，UE可以是便携式UE，例如智能手机(包括Android手机、iOS手机、Windows Phone手机等)、平板电脑、掌上电脑、笔记本电脑、移动互联网设备、或穿戴性设备，UE还可以为非便携式UE，例如智能水表、智能冰箱、台式计算机等，这里不做限定。
在NR系统中，UE的RRC存在三种状态，即空闲态、非激活态和连接态。在UE处于RRC空闲态或者非激活态时，当需要发送上行数据和/或接收下行数据时，UE需要通过随机接入过程使得UE处于RRC连接态时才能发送上行数据和/或接收下行数据。为了减少处于RRC空闲态或者非激活态的UE进行数据传输所带来的RRC信令开销与UE能耗，引入了一种PUR传输机制。在这种机制中，网络设备给UE配置周期性的PUR以及对应的PUR SS Window，UE可以利用PUR直接发送上行数据，并利用PUR SS Window接收下行数据。但是在NR系统中，处于RRC空闲态或者非激活态的UE，在传输数据前需要下行同步以及AGC调整。现有技术中，UE常常利用SSB来完成下行同步和AGC调整。但是，当SSB位于PUR之前，且SSB和PUR在时域上的间隔很大时，UE接收SSB后会进入睡眠状态，即UE需要在接收SSB时唤醒一次，在利用PUR发送上行数据时唤醒一次。UE多次唤醒，UE的功耗较大，用户体验差。下面进行详细阐述。
在NR系统中，当SSB位于PUR之前时，SSB和PUR在时域上的位置间隔可能很大。具体的，SSB的配置是小区级别的，同一个小区内的所有UE接收SSB的周期一致。但是针对同一小区内的不同UE，PUR的周期不一致，因此，SSB和PUR在时域上的位置间隔可能很大。
图1示例性的示出了UE利用SSB完成数据传输的时域示意图。如图1所示，该小区关联的SSB的周期为T1，网络设备给该小区中的一个UE配置的PUR的周期为T2，SSB和PUR在时域上的间隔Δt很大。在UE利用SSB完成数据传输的过程中，初始UE处于睡眠状态。t1时刻，即UE接收SSB的起始位置，UE第一次唤醒，UE由睡眠状态进入唤醒状态，UE唤醒后接收SSB。因为SSB和PUR在时域上的间隔Δt很大，UE在接收SSB后会进入睡眠状态。t2时刻，即UE利用PUR发送上行数据的起始位置，UE第二次唤醒，唤醒后利用PUR发送上行数据。UE多次唤醒，UE的功耗较大，用户体验差。
为了解决上述NR系统中处于RRC空闲态或者非激活态的UE利用SSB完成数据传输能耗高的问题，本申请提供了一种数据传输的方法及装置。网络设备给UE配置位于PUR和PUR SS window之间且和PUR SS window的间隔为第一值，和/或，位于PUR之前并且和PUR的间隔为第二值的参考信号。在UE处于RRC空闲态或者非激活态时，UE根据该参考信号完成数据传输过程中的下行同步和AGC调整，能够减少UE的唤醒次数，降低UE的能耗，提升用户体验。下面对本申请实施例进行详细阐述。
UE可以在两种网络中与网络设备通信：1.公共陆地网络。2.非陆地网络(例如卫星通信)。下面分别进行讨论。
在公共陆地网络中，PUR和PUR SS window在时域上的间隔小于第一阈值。UE在利用PUR SS Window接收下行数据前，需要完成下行同步以及AGC调整的场景为例，详细描述本申请实施例提供的数据传输方法。
为了保证UE利用PUR SS Window接收下行数据的可靠性，UE需要利用参考信号完成下行同步以及AGC调整。
图2是本申请实施例的提供的一种数据传输的方法流程示意图。如图2所示，包括：
步骤S201：网络设备给UE配置周期性的PUR和PUR SS Window。
在一些可行的实施方式中，在UE处于RRC连接态时，网络设备可以下发第一指示消息给UE。第一指示消息包括以下的一种或多种：PUR的周期，PUR在时域上的起始位置，PUR的周期和PUR SS Window的起始位置在时域上的间隔PUR结束位置的时域长度，PUR SS Window的时域长度。
其中，PUR为网络设备给UE配置的上行数据传输单元，PUR SS Window为网络设备给UE配置的下行数据传输单元。
步骤S202：网络设备给UE配置参考信号。
在一些可行的实施方式中，在UE处于RRC连接态时，网络设备可以根据PUR，和/或，PUR SS Window下发第二指示消息，第二指示消息包括以下的一种或多种：参考信号位于PUR与PUR SS Window之间且和PUR SS Window在时域上的间隔为第一值，参考信号在时域上位于PUR之前并且和PUR的间隔为第二值。其中第一值小于第二阈值，第二值小于第二阈值。
参考信号中包括以下的一种或多种：信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)、跟踪参考信号(Tracking Reference Signals TRS)。
步骤S203：处于RRC空闲态或者非激活态的UE进入唤醒状态，UE在唤醒状态下接收参考信号和利用PUR发送上行数据，并且在发送上行数据后保持唤醒状态。
在UE处于RRC空闲态或者RRC非激活态时使用不连续工作模式，即UE有两种模式：睡眠模式，唤醒模式。在UE处于睡眠状态时，即UE的信号的收发装置关闭，UE不能接收参考信号、不能利用PUR发送上行数据、不能利用PUR SS Window接收下行数据。在 UE处于唤醒状态时，即UE的信号的收发装置开启，UE能接收参考信号、能利用PUR发送上行数据、能利用PUR SS Window接收下行数据。
公共陆地网络中，UE与网络设备的距离近，PUR和PUR SS window在时域上的间隔小于第一阈值，UE利用PUR发送上行数据至利用PUR SS window接收下行数据之间保持唤醒状态。
处于RRC空闲态或者非激活态下的UE进行数据传输的初始状态为睡眠状态。
在一些可行的实施方式中，当参考信号位于PUR与PUR SS Window之间且和PUR SS Window在时域上的间隔为第一值时：UE由初始睡眠状态进入唤醒状态后利用PUR发送上行数据。然后，UE保持唤醒状态并接收参考信号。具体的时域示意图可参考图3a。这里不做赘述。
在另一些可行的实施方式中，当参考信号在时域上位于PUR之前并且和PUR的间隔为第二值时：UE由初始睡眠状态进入唤醒状态后接收参考信号。然后UE在接收参考信号后利用PUR发送上行数据。其中，因为参考信号和PUR在时域上的间隔第二值小于第二阈值，UE保持唤醒状态并利用PUR发送上行数据。具体的时域示意图可参考图3b。这里不做赘述。
具体的，这里的上行数据可以是业务数据，例如：图片、文字、音频、视频等。
步骤S204：唤醒状态下的UE利用参考信号进行下行同步以及AGC调整并保持唤醒状态。
具体的，为了保证UE利用PUR SS Window接收下行数据的可靠性，UE在接收下行数据前需要利用参考信号完成下行同步以及AGC调整。UE可利用CSI-RS/TRS完成下行同步以及AGC调整。
步骤S205：唤醒状态的UE利用PUR SS Window接收下行数据。
具体的，下行数据可以包括应答消息，例如：上行数据对应的HARQ-ACK、上行数据对应的ACK/NACK、重传调度信息，还可以包括业务数据。
针对本场景，现有技术中，处于RRC空闲态或者非激活态的UE利用SSB完成下行同步以及AGC调整的方法中，UE需要在接收SSB时唤醒第一次，在利用PUR发送上行数据时唤醒第二次。在本申请实施例中，UE仅需要唤醒一次就可完成一次数据传输，UE的能耗较低。
进一步的，为了保证上行数据传输的可靠性，在一些可行的实施方式中，UE需要在利用PUR发送上行数据前完成下行同步以及AGC调整。
具体的，为了保证UE发送上行数据的可靠性，UE需要在利用PUR发送上行数据前保证上行同步的有效性。UE在下行同步和AGC调整后根据时间提前量(Timing advance，TA)完成上行同步。
UE在利用PUR发送上行数据前完成下行同步以及AGC调整的场景下，参考信号只能 位于PUR之前，并且参考信号和PUR在时域上的间隔为第二值。第二值小于第二阈值。
具体的，UE唤醒后接收参考信号并完成下行同步以及AGC调整。然后再利用PUR发送上行数据并利用PUR SS Window接收下行数据，这里不做赘述。
在这种场景下，现有技术中，处于RRC空闲态或者非激活态的UE利用SSB完成下行同步以及AGC调整的方法中，UE需要在接收SSB时唤醒第一次，在利用PUR发送上行数据时唤醒第二次。在本申请实施例中，UE仅需要唤醒一次就可完成一次数据传输，UE的能耗较低。
进一步的，本申请实施例所提供的方法还可以应用于非陆地网络中，PUR和PUR SS window在时域上的间隔大于第一阈值。
下面分场景详细描述本申请实施例提供的数据传输的方法。
在利用PUR SS Window接收下行数据前，需要完成下行同步以及AGC调整的场景中，如图4所示，图4是本申请实施例的提供的另一种数据传输方法的流程示意图，包括：
步骤S401：网络设备给UE配置周期性的PUR和PUR SS Window。具体可参考步骤S201，这里不做赘述。
步骤S402：网络设备给UE配置参考信号。
在一些可行的实施方式中，网络设备可以根据PUR，和/或，PUR SS Window下发第三指示消息，第三指示消息指示参考信号位于PUR和PUR SS Window之间且和PUR SS window在时域上的间隔为第一值。具体时域图可参考图5。
步骤S403：处于RRC空闲态或者非激活态的UE进入唤醒状态，UE在唤醒状态下利用PUR发送上行数据然后进入睡眠状态。
处于RRC空闲态或者非激活态下的UE进行数据传输的初始状态为睡眠状态。
在非陆地网络中，UE与网络设备的距离远，UE与网络设备的传播时延较大，PUR和PUR SS window在时域上的间隔大于第一阈值。为了节省UE的能耗，UE在利用PUR发送上行数据后进入睡眠状态。
步骤S404：睡眠状态下的UE进入唤醒状态接收参考信号并进行下行同步以及AGC调整，UE在进行下行同步以及AGC调整后保持唤醒状态。
UE利用接收的参考信号进行下行同步以及AGC调整可参考步骤S204，这里不做赘述。
因为参考信号位于PUR和PUR SS Window之间且和PUR SS window在时域上的间隔第一值小于第二阈值，UE在接收参考信号和利用PUR SS window接收下行数据之间保持唤醒状态。
步骤S405：唤醒状态的UE利用PUR SS Window接收下行数据。可参考步骤S205。
针对本场景，现有技术中，处于RRC空闲态或者非激活态的UE利用SSB进行下行同步以及AGC调整的方法中，UE需要在利用PUR发送上行数据唤醒第一次，在接收SSB时唤醒第二次，在利用PUR SS Window接收下行数据时唤醒一次，UE总共唤醒三次来完 成一次数据传输。
在本申请实施例中，UE仅需要唤醒在利用PUR发送上行数据时唤醒一次，在接收参考信号时唤醒第二次就可完成一次数据传输，减少唤醒次数，UE的能耗较低，提升用户体验。
进一步的，为了保证上行数据传输的可靠性，在一些可行的实施方式中，UE需要在利用PUR发送上行数据前完成下行同步。同时，参考下行同步以及AGC调整具有时效性，在非陆地网络中，PUR和PUR SS Window在时域上的间隔大于第一阈值，即UE利用PUR发送上行数据和利用PUR SS Window接收下行数据之间时间间隔长，UE需要在利用PUR SS Window接收下行数据前再次进行下行同步和AGC调整。
在该场景中，图6示出了本申请实施例提出来另一种数据传输方法，如图6所示，该方法包括：
步骤S601：网络设备给UE配置周期性的PUR和PUR SS Window。具体可参考步骤S201，这里不做赘述。
步骤S602：网络设备给UE配置参考信号。
在一些可行的实施方式中，网络设备可以根据PUR，和/或，PUR SS Window下发第四指示消息，第四指示消息包括：第一参考信号位于PUR之前，且和PUR在时域上的间隔为第二值，和，第二参考信号位于PUR和PUR SS Window之间且和PUR SS window在时域上的间隔为第三值。其中，第二值小于第二阈值，第三值小于第二阈值。时域图可参考图7。
步骤S603：处于RRC空闲态或者非激活态的UE进入唤醒状态，UE在唤醒状态下接收第一参考信号并进行下行同步，之后保持唤醒状态。
为了保证UE利用PUR发送的上行数据的可靠性，UE需要利用第一参考信号完成下行同步。为了保证UE发送上行数据的可靠性，UE需要在利用PUR发送上行数据前保证上行同步的有效性。UE在下行同步后根据TA完成上行同步。
因为第一参考信号位于PUR之前，且和PUR在时域上的间隔第二值小于第二阈值，UE在接收第一参考信号和利用PUR发送上行数据之间保持唤醒状态。
步骤S604：唤醒状态的UE利用PUR发送上行数据，并且UE在利用PUR发送上行数据后进入睡眠状态。可参考步骤S403，这里不做赘述。
步骤S605：睡眠状态下的UE进入唤醒状态接收第二参考信号并进行下行同步以及AGC调整，UE在进行下行同步以及AGC调整后保持唤醒状态。
为了保证UE利用PUR SS Window接收下行数据的可靠性，UE利用接收的第二参考信号进行下行同步以及AGC调整。
因为第二参考信号位于PUR和PUR SS Window之间且和PUR SS window在时域上的间隔第三值小于第二阈值，UE在接收第二参考信号和利用PUR SS window接收下行数据 之间保持唤醒状态。
步骤S606：唤醒状态的UE利用PUR SS Window接收下行数据。可参考步骤S205。
针对本场景，现有技术中，处于RRC空闲态或者非激活态的UE利用SSB完成下行同步和AGC调整的方法中，UE需要在接收第一个SSB时唤醒第一次，在利用PUR发送上行数据唤醒第二次，在接收第二个SSB时唤醒第三次，在利用PUR SS Window接收下行数据时唤醒第四次，UE总共唤醒四次来完成一次数据传输。
在本申请实施例中，UE仅需要唤醒在接收第一参考信号时唤醒第一次，在接收第二参考信号时唤醒第二次，减少唤醒次数，UE的能耗较低，提升用户体验。
因此，通过本申请实施例所述的方法可以降低处于RRC空闲态或者非激活态下的UE在数据传输过程中的唤醒次数，节省UE的能耗，提高用户体验。
