Description

DRX的配置方法及装置
本申请要求在2018年10月18日提交中国专利局、申请号为201811216926.9的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如涉及一种非连续接收(Discontinuous Reception，DRX)的配置方法及装置。
背景技术
在相关技术中，DRX技术为无线通信系统中用于用户终端(User Equipment，UE)省电提供的一种方法。在当前的DRX机制中，可以对处于连接状态的UE进行DRX功能的配置和控制，从而使得UE无需一直检测下行信道物理下行控制信道(Physical Downlink Control Channel，PDCCH)。DRX周期由两个部分组成，(1)“工作期间”(On Duration)，在此期间UE监听PDCCH；(2)“DRX时段”，在此期间用户可以跳过下行信道的监听来节省电量。
新无线(New Radio，NR)系统中分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层引入重排序功能，接收端PDCP层对乱序的数据包进行重排序，按序将接收到的数据包投递到高层。
在新无线多连接场景下主基站(Master Node，MN)和辅基站(Secondary Node，SN)可以配置不同的DRX给UE。多连接下承载类型分为分离(Split)承载和非Split承载。对于Split承载，使用同一个PDCP实体在MN和SN不同链路上发送同一数据无线承载(Data Radio Bearer，DRB)的数据；在接收端PDCP实体需要将多条链路数据汇聚重新排序，这样，如果MN和SN或多个SN之间配置的DRX激活位置相距较远，发送端不能及时将连续接收到的数据发送，接收端PDCP实体接收到的连续数据包时差增大，重排序时长增加，业务时延增加影响用户感知。因此，基于Split承载类型的DRX配置需要进行特殊的处理。
针对相关技术中Split承载业务中终端接收到的数据包时差较大，重排复杂的问题，还没有有效的解决方案。

在一实施例中，所述第一基站和所述第二基站包括以下之一：在主基站MN和第一辅基站SN均参与所述Split承载业务的情况下，所述第一基站为第一辅基站SN，所述第二基站为主基站MN；在主基站MN和主辅基站均参与所述Split承载业务的情况下，所述第一基站为主辅基站，所述第二基站为主基站MN；在一实施例中，主辅基站可以是Split承载PDCP实体所在的基站；在MN未参与所述Split承载业务，主辅基站和第一辅基站均参与所述Split承载业务的情况下，所述第一基站为所述第一辅基站，所述第二基站为所述主辅基站。
上述可选实施例列出了三种场景，主辅基站是辅基站的一种，上述实施例为了更为清楚的表达，对主辅基站和辅基站进行了区分，但是在主基站MN参与Split承载业务时，主辅基站和辅基站是相当的。
在一实施例中，依据所述DRX周期、所述数据链路传输时延和所述时钟差值，配置所述第一基站的第一DRX起点位置，包括：计算所述DRX周期、所述数据链路传输时延和所述时钟差值三者的和值；在所述和值大于或等于所述DRX周期的情况下，配置所述和值与所述DRX周期的差值为所述第一DRX起点位置；在所述和值小于所述DRX周期的情况下，配置所述和值为所述第一DRX起点位置。
上述计算和值的步骤可以是在基站后台自身执行的。
在一实施例中，配置所述第一基站的第一DRX起点位置之后，所述第一基站依据所述第一DRX起点位置发起split承载业务。采用该方案，使得第一基站和第二基站发起的Split承载业务的时差较低，保证了终端的接收效果。
在一实施例中，第一基站接收第二基站传输的分离Split承载业务的DRX周期之前，所述第一基站检测自身是否参与所述Split承载业务；第一基站接收Split承载业务的非连续接收DRX周期，包括：第一基站在确定自身参与所述Split承载业务的情况下，所述第一基站接收所述DRX周期。
下面结合本申请另一个实施例进行说明。
本申请所要解决的技术问题是：克服相关技术中存在的多连接下DRX对Split承载业务感知的影响，提供一种多连接下非连续接收DRX的方法和装置(系统)。
本申请采用以下技术方案：
本申请所述一种多连接下DRX的方法和装置的方法包括以下步骤：
步骤210：SNi判断当前存在Split承载类型，依据MN侧传递的DRX配置，则将SNi侧DRX起点位置配置为与MN侧相同。
本申请文件的“将不同基站的DRX起点位置配置相同”并不是绝对意义的时间相同，是从终端的接收角度考虑，是为了保证终端的接收效果。
步骤220：根据MN与SNi的数据链路传输时延，计算MN侧与SNi侧时延差值ΔT，则更新SNi侧DRX起点位置为：
DRX起点位置＝Mod(DRX周期+MN侧起点位置+Mod(ΔT，DRX周期)，DRX周期)。
本申请中的DRX周期由于是周期重复的，即一个DRX周期的结束位置可以是又一个周期的开始位置，即为0。
步骤230：根据MN与SNi时钟不同步因素影响，计算MN侧与SN侧时钟差值Δt，更新SNi侧DRX起点位置为：
DRX起点位置＝Mod(DRX周期+MN侧起点位置+Mod(ΔT，DRX周期)+Mod(Δt，DRX周期)，DRX周期)。
本实施例中的Mod可以是相关技术中的取余数的意思。
在一实施例中，若多个SN进行Split承载数据的传输，MN不参与Split承载数据的传输，则主SN向其他SN传递DRX配置，其他SN依据主SN DRX配置进行各自DRX分配。
图2是本申请实施例提供的DRX配置流程示意图，如图2所示，本申请实施例提供的DRX配置流程包括以下步骤：
步骤310，SNi判断当前存在Split承载类型，依据MN侧传递的DRX配置，则将SNi侧DRX起点位置配置为与MN侧相同。
步骤320，根据MN与SNi数据链路的F1/X2/Xn传输时延，计算MN侧与SNi侧时延差值ΔT，更新SNi侧DRX起点位置
步骤330，根据MN与SNi时钟不同步因素影响，计算MN侧与SN侧时钟差值Δt，更新SNi侧DRX起点位置。
图3是本申请实施例提供的DRX参数交互示意图，如图3所示，本申请实施例提供的DRX参数交互包括以下步骤：
步骤10，MN分配MN侧DRX。
步骤20-1，传递MN侧DRX配置到SN1。

步骤30-1，根据MN侧DRX配置进行SN1侧DRX分配。
步骤30-i，根据MN侧DRX配置进行SNi侧DRX分配。
步骤40-1，为UE配置SN1侧DRX。
步骤40-i，为UE配置SNi侧DRX。

步骤520：MN传递MN侧DRX配置到SN侧。
