Abstract

本申请提供一种时间配置方法、网络设备和终端，通过根据唤醒期间确定参考信号的发送时间，或者通过参考信号的发送时间确定唤醒期间，使得参考信号的发送时间与唤醒期间关联，进而避免UE无法接收参考信号，或者或UE需要频繁地醒来以接收参考信号的技术问题。

Description

一种时间配置的方法、网络设备及UE 技术领域
本申请涉及通信技术领域，尤其涉及一种时间配置的方法、网络设备及UE。
背景技术
现有长期演进(Long Term Evolution，LTE)系统的无线资源管理(Radio Resource Management，RRM)方法采用基于下行信号的测量方式，即网络设备发送下行参考信号，例如固定时频位置的小区(cell)专用参考信号(Cell-specific Reference Signal，CRS)，终端设备测量该网络设备发送的CRS的参考信号接收功率(Reference Signal Received Power，RSRP)/参考信号接收质量(Reference Signal Received Quality，RSPQ)等测量结果并上报给网络设备，由网络设备来决定终端设备的切换和移动。在下一代无线通信系统(NR)中，为了UE的移动性，可以配置UE采用信道状态信息参考信号(channel state information Reference Signal，CSI-RS)进行测量，不同小区cell的CSI-RS不必要求在一个测量窗口中发送，即发送时间不相同。但是对于不连续接收(Discontinuous Reception，DRX)UE而言，UE为了节省功耗，周期性地醒来，并在唤醒(on duration)期间中读取PDCCH信号和寻呼(paging)信息以及其他操作，而在休眠(off duration)期间为了节省能量则停止监控PDCCH信号甚至关闭收发机，此时则无法接收CSI-RS或者为了接收CSI-RS需要额外消耗电量。

下面将结合附图，对本申请实施例中的技术方案进行描述。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。

2)、用户设备(user equipment，UE)是一种具有无线收发功能的设备可以和网络设备进行交互，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述UE可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)UE设备、增强现实(Augmented Reality，AR)UE设备、工业控制(industrial control)中的无线UE、无人驾驶(self driving)中的无线UE、远程医疗(remote medical)中的无线UE、智能电网(smart grid)中的无线UE、运输安全(transportation safety)中的无线UE、智慧城市(smart city)中的无线UE、智慧家庭(smart home)中的无线UE等等。本申请的实施例对应用场景不做限定。UE可以是能和网络设备通信的设备。UE有时也可以称为终端设备、接入终端设备、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、无线通信设备、UE代理或终端装置等。
3)小区(cell)，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。另外，该小区还可以是超小区(Hypercell)。小区还包括服务小区(serving cell)和邻小区(neighboring cell)。服务小区是当前为UE提供服务的小区，邻小区是与服务小区相邻或者相近的小区。
4)、交互，本申请中的交互是指交互双方彼此向对方传递信息的过程，这里传递的信息可以相同，也可以不同。例如，交互双方为网络设备1和网络设备2，或是可以是网络设备与UE。可以是网络设备1向网络设备2请求信息，网络设备2向网络设备1提供网络设备1请求的信息。当然，也可以网络设备1和网络设备2彼此向对方请求信息，网络设备与UE的交互与上述网络设备之间的交互相同，在此不再赘述。这里请求的信息可以相同，也可以不同。
5)、“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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
6)、名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。信息(information)，信号(signal)，消息(message)，信道(channel)有时可以混用， 应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
下面将结合附图，对本申请中的技术方案进行描述。
图1为了本申请应用的一种系统的示意图。如图1所示，系统100可以包括网络设备102以及终端设备104、106、108、110、112和17，其中，网络设备与终端设备之间通过无线连接。应理解，图1仅以系统包括一个网络设备为例进行说明，但本申请并不限于此，例如，系统还可以包括更多的网络设备；类似地，系统也可以包括更多的终端设备。还应理解，系统也可以称为网络，本申请对此并不限定。
图2为举例地可以应用本申请的一种网络架构示意图，该网络架构示意图可以是下一代无线通信系统中的NR的网络架构图。在该网络架构示意图中，网络设备可以被分为一个集中式单元(Centralized Unit，CU)和多个传输接收点(Transmission Reception Point，TRP)/分布式单元(Distributed Unit，DU)，即网络设备的基于带宽的单元(Bandwidth Based Unit，BBU)被重构为DU和CU功能实体。需要说明的是，集中式单元、TRP/DU的形态和数量并不构成对本申请的限定。图2所示的网络设备1和网络设备2各自对应的集中式单元的形态虽然有所不同，但是并不影响各自的功能。可以理解的是，集中式单元1和虚线范围内的TRP/DU是网络设备1的组成元素，集中式单元2和实线范围内的TRP/DU是网络设备2的组成元素，网络设备1和网络设备2为NR系统中涉及的网络设备(或称为基站)。CU可以处理无线高层协议栈功能，例如无线资源控制(Radio Resource Control，RRC)层，分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)层等，甚至也能够支持部分核心网功能下沉至接入网，术语称作边缘计算网络，能够满足未来通信网络对于新兴业务例如视频，网购，虚拟/增强现实对于网络时延的更高要求。DU可以主要处理物理层功能和实时性需求较高的层2功能，考虑到无线远端单元(Radio Remote Unit，RRU)与DU的传输资源，部分DU的物理层功能可以上移到RRU，伴随RRU的小型化，甚至更激进的DU可以与RRU进行合并。CU可以集中式的布放，DU布放取决实际网络环境，核心城区，话务密度较高，站间距较小，机房资源受限的区域，例如高校，大型演出场馆等，DU也可以集中式布放，而话务较稀疏，站间距较大等区域，例如郊县，山区等区域，DU可以采取分布式的布放方式。图2所举例的S1-C接口，可以为网络设备与核心网之间的标准接口，具体S1-C所连接的设备未在图2中示出。
在NR中，可以配置UE采用CSI-RS进行移动性测量，同时配置CSI-RS发送时间与UE的唤醒期间关联，进而减少测量失败的可能性，同时减少耗电。其中唤醒期间可以称为on duration period或on duration或on period举例来说，假设UE测量三个cell(A/B/C),其中cell A是UE的服务小区(serving cell)。cell A(或者网络设备，或者网络设备通过cell A)向UE发送三个cell的CSI-RS的配置信息，UE获得三个cell的CSI-RS的配置信息，该配置信息包括CSI-RS的发送时间(即参考信号的发送时间)，UE在对应的发送时间和时频资源上接收三个cell的CSI-RS。在本申请中，三个cell的CSI-RS的发送时间都在该UE的唤醒期间内，其中，UE可以是连接状态的DRX UE(C-DRX UE)。
下面介绍根据唤醒期间确定参考信号的发送时间的具体方案。确定的发送时间是通过配置信息发送给UE的，之后网络设备在发送时间发送参考信号，UE在发送时间接收参考信号。在介绍具体方案之前，为便于理解，先介绍UE的唤醒期间，发送时间在唤醒期间内等各种情况。
图3是本申请UE的唤醒期间与参考信号的示意图。图3展示的是需要接收所述参考信号的所有UE中，至少一个UE的唤醒期间，其中的on指每个UE单独的唤醒期间。图3A、图3B、图3C、图3D仅示例性的，应该理解的是本申请中可以有更多或者更少的UE。图3A是需要接收所述参考信号的所有UE中，一个UE，UE1的唤醒期间。图3B是需要接收所述参考信号的所有UE中，三个UE的唤醒期间，其中UE1、UE2、UE3各自的唤醒期间不同。应该理解的是，这三个UE可以是需要接收参考信号的所有UE。图3C是需要接收所述参考信号的所有UE中，两个UE的唤醒期间，其中UE1和UE2各自的唤醒期间相同。对应相同的唤醒期间可以只配置一个参考信号。图3D是需要接收所述参考信号的所有UE中，四个UE的唤醒期间，其中UE1和UE2各自的唤醒期间相同，UE3和UE4各自的唤醒期间相同。此时UE1和UE2可以被认为是一组，UE3和UE4可以被认为是一组。可以由网络设备根据预设的规则分组。具体的分组规则可以是，将唤醒期间相同或者近似的UE分为一组，或者将地理位置临近的UE分为一组，或者移动速度相近的UE分为一组。
图4是本申请UE的唤醒期间示与参考信号的另一种示意图。图4展示的是需要接收所述参考信号的所有UE中，至少两个UE重叠的唤醒期间，其中的on指每个UE单独的唤醒期间。图4A、图4B、图4C、图4D仅示例性的，应该理解的是本申请中可以有更多或者更少的UE。图4A是需要接收所述参考信号的所有UE中，两个UE重叠的唤醒期间，从图中可知，二者有部分重叠。图4C是需要接收所述参考信号的所有UE中，两个UE重叠的唤醒期间，其中UE1和UE2的唤醒期间完全重叠，完全重叠的UE可以被认为是一组，其分组规则与图3中的描述相同。图4B是需要接收所述参考信号的所有UE中，三个UE的重叠的唤醒期间，其中包括UE1和UE2重叠的唤醒期间1以及，UE2和UE3重叠的唤醒期间2。本申请的重叠的唤醒期间可以是二者中的任一种，或者二者都包括。图4D是需要接收所述参考信号的所有UE中，三个UE重叠的唤醒期间，其中重叠的唤醒期间可以是两个UE重叠的唤醒期间，如重叠的唤醒期间1、重叠的唤醒期间2、中的任意一个；也可以三个UE重叠的UE的唤醒期间3，本申请对此不做限制。
图5是发送时间与UE的唤醒期间的关系示意图，为简化描述，图5仅以图3A为例示例性的展示发送时间与唤醒期间的关系，应该理解的是，发送时间与唤醒期间的关系可以包括图5中任意一种或者多种情况。如图5A所示，发送时间在唤醒期间内；如图5B所示，发送时间与唤醒期间有部分重叠；如图5C所示，发送时间与唤醒期间有规律的间隔。应该理解的是，发送时间和唤醒期间还可以有其他关系，图5只是示例性说明，不构成限制。
图6是图5A基础上的进一步细化，图6发送时间在唤醒期间内的示意图，如图6所示，所述发送时间在所述唤醒期间内，包括下述一种或者多种：图6A是所述发送时间的起点与所述唤醒期间的起点相同的示意图；图6B是所述发送时间的终点与所述唤醒期间的终点相同的示意图；图6C是所述发送时间的起点在所述唤醒期间的起点之后，所述发送时间的终 点在所述唤醒期间的终点之前的示意图。
图7是本申请根据唤醒期间确定发送时间的流程示意图，如图7所示，该方法包括：
S601，网络设备根据用户设备UE的唤醒期间确定参考信号的发送时间。
举例来说，服务基站统计所有需要配置CSI-RS的UE(该UE可以是DRX UE，或者更进一步的是连接态的DRX UE)，并根据UE的DRX配置，计算出至少两个UE重叠的唤醒期间。根据计算出UE重叠的唤醒期间，将serving cell和neighboring cell的CSI-RS资源(参考信号的发送时间)配置在重叠的唤醒期间内。
举例来说，服务基站统计所有需要配置CSI-RS的UE，并根据UE的DRX配置对UE进行分组，并计算出每组UE的重叠的唤醒期间。根据计算出每组UE的重叠的唤醒期间，将该组UE的serving cell和neighboring cell的CSI-RS资源配置在重叠的唤醒期间内。
举例来说，服务基站统计所有需要配置CSI-RS的UE，并根据UE的DRX配置，计算出所有的UE的唤醒期间。根据计算出所有UE的On duration期间，将serving cell和neighboring cell的CSI-RS资源配置在所有的唤醒期间内。
可选的，S601可以包括：所述网络设备根据所述唤醒期间和所述参考信号的时间配置信息表，确定所述参考信号的发送时间。示例性的，CSI-RS的时间配置信息表如表一所示。CSI-RS的时间配置信息可以是CSI-RS subframe configuration和UE唤醒期间的交集。
Figure PCTCN2018098902-appb-000001
表一
可选的，所述网络设备将所述时间配置信息表中的发送时间与所述唤醒期间取交集，之后从所述交集中选取所述参考信号的发送时间。如果交集中有多个发送时间，网络设备可以随机的或者周期性的或者综合考虑其他因素来选取一个或者多个发送时间。
示例性的，根据表一，如果I CSI-RS＝5，则表示从第0号子帧开始发送CSI-RS，CSI-RS的发送周期是5ms，即第0/5/10/15/….号子帧都发送CSI-RS。根据UE的DRX配置得到UE的on duration period包括第5号、第6号、第7号、第8号、第9号和第10号这6ms的子帧。将表一与该UE的唤醒期间取交集，得到第5和第10号子帧。即网络设备可以配置在第5和/或第10号子帧上发送CSI-RS。
S602，所述网络设备在所述发送时间向UE发送参考信号。
通过将参考信号的发送时间与UE的唤醒期间建立关系，实现了尽量在UE的唤醒期间接收参考信号，进而减少了接收失败的肯能性，同时UE也不用频繁的醒来来接收参考信号，节省了电量。
下面介绍根据参考信号的发送时间确定唤醒期间的具体方案。网络设备配置UE的唤醒 期间，并将配置结果发送给UE，UE接收到该信息之后，根据网络设备配置的唤醒期间，周期性的唤醒，并在参考信号的发送时间接收参考信号。
在介绍具体方案之前，先介绍UE的唤醒期间，因为是根据发送时间来确定唤醒期间，那么很容易理解，这里的唤醒期间包括所有需要接收参考信号的UE的唤醒期间，当然本申请可以对其进行分组，那么此时的唤醒期间指的是需要接收所述参考信号的至少一组UE中，每个UE的唤醒期间。具体的UE的唤醒期间与参考信号的关系可以参考图3和图4的描述。
在介绍UE的唤醒期间之后，需要了解唤醒期间与参考信号发送时间的关系，虽然下面介绍的方法是根据发送时间确定UE的唤醒期间，与上面介绍的根据UE的唤醒期间确定发送时间有些不同，但是具体到唤醒期间与发送时间的关系仍然可以参考图5及其文字描述，在此不再赘述。
需要说明的是，UE的唤醒期间包含所述参考信号的发送时间与图5A中发送时间在唤醒期间内，二者在实质关系上可以理解为一致。因此，所述UE的唤醒期间包含所述参考信号的发送时间的具体情况可以参考图6及其文字描述，在此不再赘述。
图8是本申请根据发送时间确定唤醒期间方法的流程示意图，如图8所示：该方法包括：S701，网络设备根据参考信号的发送时间确定UE的唤醒期间。举例来说，可以是服务网络设备配置每个UE或一组UE的DRX配置参数，使唤醒期间包含下述CSI-RS的测量窗口。
可选的，在S701之前，所述方法还包括S700，所述网络设备确定所述参考信号的发送时间。举例来说，可以是服务基站将每个UE或一组UE的serving cell和neighboring cell的CSI-RS资源周期性地配置在CSI-RS测量窗口中。
S702，所述网络设备向UE发送所述参考信号。网络设备在发送时间向UE发送所述参考信号。
