多链接配置方法、基站及用户设备 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种多链接配置方法、基站及用户设备。
背景技术
超密集网络(Ultra-DenseNetwork，UDN)是第五代移动通信(the 5th Generation Mobile Communication，5G)的一项重要技术。UDN是指在网络部署时，针对某些数据需求量大、数据连接数多的热点区域(例如体育赛场、火车站候车厅、办公场所等)，进行超密集的组网，即在该些热点区域大规模地部署小小区基站，相邻的小小区基站之间可能只距离数十米。
UDN中，小小区基站的覆盖范围小，即使用户设备(User Equipment，UE)以中低速移动，也会引发频繁的切换。切换一方面增加了空口的信令开销，另一方又会引发数据中断。因此，如何解决UE在UDN网络中频繁切换的问题，实为业界亟待解决的问题。

具体实施方式
目前，UDN中，由于部署的小小区基站特别多，小小区基站的覆盖范围小，即使用户设备(User Equipment，UE)以中低速移动，也会引发频繁的切换。因此，部署UDN时，如何解决UE在UDN网络中频繁切换的问题，实为为业界亟待解决的问题。
有鉴于此，本发明实施例提供一种多链接配置方法、基站及用户设备，通过为用户设备配置多链接，以解决UE在UDN网络中频繁切换的问题。
本文中描述的技术可用于各种通信系统，例如当前2G，3G通信系统和下一代通信系统，例如全球移动通信系统(Global System for Mobile communications，GSM)，码分多址(Code Division Multiple Access，CDMA)系统，时分多址(Time Division Multiple Access，TDMA)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)，频分多址(Frequency Division Multiple Addressing，FDMA)系统，正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)系统，单载波FDMA(SC-FDMA)系统，通用分组无线业务(General Packet Radio Service，GPRS)系统，长期演进(Long Term Evolution，LTE)系统，UDN系统、E-UTRA系统以及其他此类通信系统。
本申请中涉及的用户设备，可以是无线终端，该无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连 接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
本申请中涉及的小小区基站，即传输点，可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。
另外，本发明不受限于低频系统，可以是高频毫米波系统，因此所述相关测量及所有相关配置都可以是针对波束赋形(beamforming)的，即基于波束beam的。
下面，为描述方便、清楚起见，以系统架构具体为UDN系统为例对本发明技术方案进行详细描述。具体的，请参见图1。
图1为本发明多链接配置方法所适用的UDN的架构示意图。如图1所示，本架构包括宏基站和五个传输点，即小小区基站1～5，其中，小小区基站1、2、3、5为UDN中相邻的三个小小区基站，小小区基站4为与小小区基站1、2、3、5不相邻的小小区基站。假设为UE配置的第一集合包括的传输点为小小区基站1、2、3、5，由于第二集合为第一集合的子集，因此第二集合包含的传输点可以为1、3，或者，第二集合包含的传输点可以为2、3等。
需要说明的是，小区虚拟化技术中，UE周围的多个传输点组成一个虚拟小区，来为用户提供服务。虚拟小区的资源构成和设置可以根据用 户的移动、业务需求等动态配置和更改，也可以协调传输节点的休眠和信号发送。在这些传输节点中，一个传输节点被选为主传输节点。
下面，在图1的基础上，对本发明多链接配置方法进行详细说明，具体的，可参见图2。
图2为本发明多链接配置方法实施例一的信令图。本实施例中，基站用户设备交互，适用于需要多链接配置的场景。具体的，本实施例包括如下步骤：
101、用户设备UE生成上行信息。
本步骤中，UE根据下行信号或上行信号生成上行信息。例如，UE可通过如下方式生成上行信息：
方式一、上行信息具体为大于所述第一阈值或所述第二阈值的下行测量结果，此时，UE对至少一个传输点的下行信号进行测量，例如，进行RRM测量，得到至少一个下行测量结果，从所述至少一个下行测量结果中，确定出所述大于所述第一阈值或所述第二阈值的下行测量结果，并将大于所述第一阈值或所述第二阈值的下行测量结果作为上行信息。
方式二、行信息具体为大于所述第一阈值或所述第二阈值的下行测量结果对应的传输点标识。此时，UE对至少一个传输点的下行信号进行测量得到至少一个下行测量结果；从所述至少一个下行测量结果中，确定出大于所述第一阈值或所述第二阈值的下行测量结果对应的传输点标识。例如，UE对所述大于所述第一阈值或所述第二阈值的下行测量结果对应的传输点标识进行升序或降序排列，从而得到上行信息。
方式三、上行信息具体为所述UE发送的上行信号，所述上行信号为下述信号中的至少一种：上行探测信号、上行探测参考信号、上行序列码或前导码。
该种方式下，上行信息就是UE发送的上行探测信号、上行序列码或前导码等至少一种上行信号。
102、用户设备UE向基站发送所述上行信息。
本步骤中，UE将101中的上行信息发送给基站。当上行信息采用上述方式三生成时，UE先接收所述基站通过无线资源控制RRC信令通知的所述上行信号的上行传输子帧或上行传输子帧集合，然后，在该上行传输子帧或 上行传输子帧集合包含的子帧上向基站发送上行信息。该过程中，上行传输子帧或所述上行传输子帧集合为所述基站通过基站间接口协调或预配置的。
103、所述基站根据所述上行信息为所述UE配置第一集合和/或第二集合；
其中，当配置第一集合或第二集合时，所述第一集合或第二集合包含的各传输点与所述UE之间建立多链接；当配置第一集合和第二集合时，所述第一集合包含至少两个传输点，所述第二集合为所述第一集合的子集。
请参照图1，本发明实施例中，基站例如为宏基站或marco eNB或主节点master node(图中未示出)。本步骤中，所述第一集合中的传输点为所测量的信号强度大于或大于等于第一阈值的传输点，所述第二集合中的传输点为所测量的信号强度大于或大于等于第二阈值的传输点，所述第二阈值高于所述第一阈值。所述第二集合包含的各传输点可从所述第一集合中激活或去激活。UE移动时，当所述第二集合包含的传输点不满足所述第二阈值时，例如，第二集合中的传输点的信号差或者中断时，将所述第一集合中、第二集合外满足所述第二阈值的传输点加入所述第二集合中。其中，所测量的信号强度为无线资源管理RRM测量,可以包括参考信号接收功率RSRP(reference signal receiving power)，参考信号接收质量RSRQ(reference signal receiving quality)，接收的信号强度指示RSSI(Received Signal Strength Indication)或任何基于beam的测量参数中的至少一种。
本发明实施例提供的多连接配置方法，UE生成上行信息并发送给基站，基站根据上行信息为UE配置第一集合和/或第二集合，当配置第一集合或第二集合时，第一集合或第二集合包含的各传输点与UE之间建立多链接；当配置第一集合和第二集合时，第一集合包含至少两个传输点，第二集合为第一集合的子集。该过程中，第一集合包含的传输点为备选的传输点，第二集合包含的传输点与用户建立多链接，为实际与UE之间传输数据的传输点，当第二集合包含的传输点的信号差或者中断时，从第一集合中选取出质量好的传输点并加入到第二集合，减少链路中断、服务中断的次数，从而解决UE在UDN网络中频繁切换的问题。
可选的，上述实施例中，第一集合包含的传输点形成第一小区，第一小 区包含的主传输点固定或可变。该第一小区为第一簇、第一虚拟小区或第一超级小区。并且，第一簇具有对应的簇标识，第一虚拟小区具有对应的虚拟小区标识，第一超级小区具有对应的超级小区标识。
可选的，上述实施例中，第二集合包含的传输点形成第二小区，第二小区包含的主传输点随UE的移动发生变化。第二小区为第二簇、第二虚拟小区或第二超级小区。第二簇具有对应的簇标识，第二虚拟小区具有对应的虚拟小区标识，第二超级小区具有对应的超级小区标识。
可选的，上述实施例中，所述第二集合为多RRC链路模式，所述第二集合中的至少两个传输点与所述UE建立RRC链接。或者，所述第二集合为单RRC链路模式，所述第二集合中的一个传输点与所述UE建立RRC链接；或者，所述第二集合为半静态模式，所述第二集合中的传输点以半静态的方式在所述第一集合中改变。具体的，可参见图3，图3为本发明多链接配置方法实施例二中部署宏基站的多RRC链路模式和单RRC链路模式的示意图。
请参照图3，有宏基站(overlay)的场景中，假设第二集合包括的传输点为小小区基站D、小小区基站E和小小区基站F，如果工作于多RRC链路模式下，UE可以保留到宏基站和传输点small cell D的RRC链接，如图中多RRC链路模式下的实线箭头所示(虚线箭头表示未建立RRC链接)；假设第二集合包括的传输点为小小区基站A、小小区基站B和小小区基站C，如果工作于单RRC链路模式下，UE只保留到宏基站的RRC链接，如图中单RRC链路模式下，UE保留与宏基站的RRC链接，而虚线所述的UE与小小区基站A、小小区基站B以及小小区基站C的RRC连接未保留。
图4为本发明多链接配置方法实施例三中未部署宏基站的多RRC链路模式和单RRC链路模式的示意图。请参照图4，独立(stand alone)场景中，假设第二集合包括的传输点为小小区基站D、小小区基站E和小小区基站F，如果工作于多RRC链路模式下，UE可以保留到传输点small cell D和F的RRC链接，如图中多RRC链路模式下的实线箭头所示，也就是说，可以保留第二传输点激活中的所有传输点与UE的RRC链接，也可以包括第二传输点集合中的部分传输点与UE的RRC链接；如果工作于单RRC链路模式下，假设第二集合包括的传输点为小小区基站A、小小区基站B和小小区基站C，UE 只保留到传输点small cell A的RRC链接，也就是说，只保留第二集合中的一个传输点与UE的RRC链接。
上述图3与图4中，无论上述多RRC链路模式或者单RRC链路模式，为了保证传输点的能量均衡，可以在各个满足传输要求的传输点之间进行半静态转换，其中，满足传输要求指测量信号强度大于或大于等于预定的门限值。具体的，可请参照图5。
图5为本发明多链接配置方法实施例四中第二集合包含的传输点半静态切换的示意图。请参照图5，随着时间的推移，即子帧的推移，第一个周期内，第二集合包含的传输点可以为小小区基站A与小小区基站B，第二个周期内，第二集合包含的传输点可以变更为小小区基站B与小小区基站C，第三个周期内，第二集合包含的传输点可以变更为小小区基站C与小小区基站A。如果是多RRC链路模式，任何半静态转换的传输点中需要有至少一个传输点能保持与UE的链接。
可选的，上述实施例中，基站预先通过配置信令向UE发送第一阈值，使得UE向基站发送满足第一阈值的传输点的上行信息，避免UE对所有的传输点的上行信息都进行发送带来的信息量大、占用资源多的弊端。
可选的，上述实施例中，基站根据上行信息为UE配置第一集合和/或第二集合之后，基站向UE或传输点发送第一和/或第二集合的配置信息。例如，基站通过无线资源控制RRC信令向UE发送第一集合和第二集合的信息；再如，基站通过媒体接入控制MAC信令向UE发送第二集合的激活或去激活信息。
可选的，上述实施例中，基站在为用户配置好第一集合和第二集合后，通过RRC信令向所述UE发送多链接的配置信息，以通知所述UE进行多链路协作。其中，多链接协作包括下述协作中的至少一种：功率协作、随机接入协作与功率余量协作。
可选的，上述实施例中，多链路中，未激活的链路被激活时，所述基站通过已激活链路上的媒体接入控制MAC信令触发被激活的链路进行上行传输，所述上行传输包括下述传输中的至少一种：随机接入传输、调度需求传输、探测参考信号传输、缓存状态报告传输。
可选的，上述实施例中，基站具体为宏基站marco eNB或主节点master  node，传输点为小小区基站。
图6为本发明多链路配置方法实施例五的配置示意图。请参照图6，本实施例中，宏基站覆盖的区域内包括小小区基站A与小小区基站B，小小区基站A与小小区基站B形成虚拟小区，其中小小区基站A是该虚拟小区中的主节点或主小区，小小区基站B是该虚拟小区中的辅节点或辅小区。UE首先被连接到小小区基站A上。当UE逐渐靠近小小区基站B时，作为一种实施例，UE可以向宏基站汇报该信息。接着，宏基站在与小小区基站A及小小区基站B的X2接口上做一些协调，决定UE可以被配置“MC”模式，并且通过信令通知UE该“MC”模式，此时，UE将与小小区基站A与小小区基站B建立链接。虚拟小区中小小区基站的部分系统信息可以通过小小区基站A下发，例如，虚拟小区ID及系统带宽等。其余系统信息及UE特定的配置可以通过辅小区如小小区基站B下发。宏基站可以进一步通过RRC信令将多链接的配置信息发送给小小区基站A、小小区基站B与UE。之后，UE进行多链路协作，如功率协作、随机接入协作与功率余量协作等。
作为上述的另一种实施例，UE可以向小小区基站A汇报该信息。接着，小小区基站A在与小小区基站B的X2接口上做一些协调，决定UE可以被配置“MC”模式，并且通过信令通知所述UE该“MC”模式，此时，UE将与小小区基站A与小小区基站B建立链接。虚拟小区中小小区基站的部分系统信息可以通过小小区基站A下发，例如，虚拟小区ID及系统带宽等。其余系统信息及UE特定的配置可以通过辅小区如小小区基站B下发。小小区基站A可以进一步通过RRC信令将多链接的配置信息发送给小小区基站B与UE。之后，UE进行多链路协作，如功率协作、随机接入协作与功率余量协作等。
