Description

非授权载波资源处理方法及装置 技术领域
本申请涉及但不限于通信领域，尤其涉及一种非授权载波资源处理方法及装置。
背景技术
第三代移动通讯伙伴计划(3rd Generation partnership project，简称为3GPP)标准规范的长期演进(Long-Term Evolution，简称为LTE)系统，在Rel-12版本引入了非常重要的双连接(Dual Connectivity，简称为DC)功能，使得单个UE可以同时和两个LTE基站，主基站(Master eNodeB，简称为MeNB)和辅基站(Secondary eNodeB，简称为SeNB)，进行无线连接和上下行用户业务数据的收发传输。如图1所示，图1是相关技术中的LTE DC架构图，其中，处于LTE DC工作模式下的用户设备(User Equipment，简称为UE)，能够同时与主基站(MeNB)和辅基站(SeNB)通过Uu-U空口用户面承载数据无线承载(Data Radio Bearer，简称为DRB)(每个DRB对应和承载一条用户业务数据流)进行上下行业务数据的双工通信；其中，MeNB是UE无线资源控制(Radio Resource Control，简称为RRC)锚点控制网元，通过Uu-C空口控制面承载信令无线承载(Signaling Radio Bearer，简称为SRB)，负责UE的移动性/空口无线资源配置控制管理等功能；SeNB必须通过X2-U地面接口用户面和X2-C地面接口控制面挂靠连接在MeNB下，为UE提供额外的业务数据分流和承载，以此来增强UE的总体数据传输率。MeNB可以和LTE核心网的控制面网元移动性管理实体(Mobile Management Entity，简称MME)和用户面网元服务网关(Serving Gateway，简称为SGW)相连接，分别对应S1-MME和S1-U(MeNB)地面接口，而SeNB只能和用户面网元SGW相连接，对应S1-U(SeNB)地面接口。UE与LTE核心网的非接入层控制信令交互只能通过MeNB来实现，UE与LTE接入网的接入层控制信令交互也只能通过MeNB来实现；而UE与LTE核心网和接入网的业务数据交互既可以通过MeNB配置的主小区集合(Master Cell Group，简称为MCG) 承载(Bearer)来实现，也可以同时通过SeNB配置的MCG Bearer来实现；SeNB与MME或者UE进行控制信令交互时，必须通过MeNB的中转协商转发来实现。
LTE DC工作模式可以提供三种基本的DRB类型，图2是相关技术中的DRB类型示意图，如图2所示，图2中的(a)中虚线为MCG Bearer，通过MCG实现用户业务数据的上下行传输；图2中的(b)中虚线为分割承载(Split Bearer)，通过MCG和辅小区集合(Secondary Cell Group，简称为SCG)同时实现用户业务数据的上下行传输；图2中的(c)中虚线为辅小区集合承载(SCG Bearer)，通过SCG实现用户业务数据的上下行数据传输。
3GPP标准规范的LTE系统，在Rel-13版本又引入了非常重要的授权辅助接入(Licensed Assisted Access，简称为LAA)功能，即可以联合聚合多个授权载波和非授权载波资源。如图3所示，图3是相关技术中的LTE LAA简化架构图，在LTE LAA载波聚合的简化架构中，基站(eNB)或者UE作为数据收发端，媒体接入控制(Media Access Control，简称为MAC)协议实体中配置有N个并行的混合自动重传请求(Hybrid Automatic Repeat Request，简称为HARQ)实体(每个HARQ实体对应一个载波，能对多条用户业务数据流的数据块进行复用处理)，但是其中一部分是服务授权载波的传统HARQ实体，而另外一部分是服务非授权载波的LAA-HARQ实体(需要对传统HARQ实体针对非授权载波的使用特性进行一些改进，因此加以区分)；N个并行的HARQ实体能够同时最大产生/接收的N个HARQ数据包(或者MAC协议数据单元(Protocol Data Unit，简称为PDU))，它们各自经过对应物理层(PHY)实体的一系列相关处理(例如：信道编码交织，调制解调，物理资源块适配映射，波形形成等)，最后转化为LTE特定的物理层无线信号，其中一部分是在授权载波上的服务小区内进行收发，如MCG中的主服务小区(Pcell，Primary Cell)，SCG中的主服务小区PScell，或者MCG/SCG中的授权辅服务小区(Scell，Secondary Cell)，而另外一部分则要在非授权载波上的服务小区内进行收发，如MCG/SCG中的非授权辅服务小区(LAA Scells)。这里也做了传统PHY实体和改进LAA-PHY实体的区分，以表达针对LAA特性功能上的改进。理想情况下，UE允许如下的LAA 载波聚合配置：
Pcell+MCG内若干个授权的Scell(MCG)+MCG内若干个非授权的LAA Scell(MCG)+PScell+SCG内若干个授权的Scell(SCG)+SCG内若干个非授权的LAA Scell(SCG)。
根据载波聚合(Carrier Aggregation，简称为CA)的原始定义和设计(不同载波间的资源聚合)，通常情况下，Pcell、Scell(MCG)、LAA Scell(MCG)、PScell、Scell(SCG)、LAA Scell(SCG)都是被异频配置的，即必须处于不同的载波频点上，这样频分的方式天然可以减少不同服务小区之间的无线干扰，否则如果两个同频配置的服务小区在同一时间段为UE同时调度发送数据包，UE可能无法彼此识别和区分信噪和正确接收解码两个数据包，造成空口无线资源的低效使用。
对于Pcell、Scell(MCG)、PScell、Scell(SCG)，由于都被配置在授权载波频点上(被某运营商独家购买，独自占用和使用)，因此彼此间异频关系的配置是可操作的，但是LAA Scell(MCG)、LAA Scell(SCG)之间的异频关系配置是否有必要呢？从DC的常规部署看，通常MeNB和SeNB基站物理距离相隔较远，在非授权频段内处于不同的无线干扰环境，图4是相关技术中的DC配置以及DC+LAA配置的示意图。其中，图4中的(a)所示为：某运营商A的宏基站在某区域的授权载波1上部署了宏小区覆盖，微基站在相同宏小区覆盖的子区域内的授权载波3上部署了微小区覆盖(用于系统容量增强)；某时刻UE进入宏微小区的重叠覆盖区域，从而MeNB决定给UE配置DC工作模式，此时UE和MeNB建立主链路，完成配置Pcell；UE和SeNB建立辅链路，完成配置PScell(该示例和下面的示例中，为了简化，都忽略了Scell(MCG)和Scell(SCG))；虽然在宏小区覆盖内还有多个相邻的无线局域网(Wireless Local Area Network，简称为WLAN)接入点(Access Point，简称为AP)节点，但是由于它们被配置运行在异频的非授权频段内，因此它们不会对UE的DC工作运行带来任何的无线干扰。
进一步地，如图4中的(b)所示：假设MeNB，SeNB和UE都具备LAA能力，因此MeNB在某非授权载波2上部署了LAA增容小区(工作频点和带宽由自己确定)，SeNB在某非授权载波4上也部署了LAA增容小区(工 作频点和带宽由自己确定)，当UE进入到前述LAA增容小区共同覆盖区域的时候，MeNB可以进一步为UE配置一个LAA Scell(MCG)和Pcell联合做LAA CA，SeNB可以进一步为UE配置一个LAA Scell(SCG)和PScell联合做LAA CA。和MeNB相邻的WLAN AP节点如果和LAA Scell(MCG)同频或者有工作带宽重叠，则会和MeNB形成非授权载波资源的竞争关系，在某段时刻，如果WLAN竞争先抢占到某非授权载波2上的无线资源，则MeNB需要回退等待到下一个时刻再去尝试抢占资源，从而无法利用LAA Scell(MCG)同时和UE进行数据传输。和SeNB相邻的WLAN AP节点如果和LAA Scell(SCG)同频或者有工作带宽重叠，则会和SeNB形成非授权载波资源的竞争关系，在某段时刻，如果WLAN竞争先抢占到某非授权载波4上的无线资源，则SeNB需要回退等待到下一个时刻再去尝试抢占资源，从而无法利用LAA Scell(SCG)同时和UE进行数据传输。因此LAA Scell(MCG)和LAA Scell(SCG)是否能被使用于数据增强传输，取决于本地竞争干扰情况和LBT(Listen Before Talk，先听后说)的结果。
进一步地，如图4中的(c)所示：假设MeNB，SeNB和UE都具备LAA能力，因此MeNB在某非授权载波2，4上同时部署了两个LAA增容小区，SeNB在同频的非授权载波2，4上也部署了两个LAA增容小区，当UE进入到前述LAA增容小区共同覆盖区域的时候，MeNB可以为UE配置两个LAA Scells(MCG)和Pcell联合做LAA CA，SeNB可以为UE配置两个LAA Scells(SCG)和PScell联合做LAA CA。和MeNB，SeNB相邻的WLAN AP节点如果和LAA Scells(MCG),LAA Scells(SCG)同频或者有工作带宽重叠，则会和MeNB，SeNB形成非授权载波资源的竞争关系，在某段时刻，如果WLAN竞争先抢占到非授权载波2，4上的无线资源，则MeNB，SeNB需要回退等待到下一个时刻再去尝试抢占资源，无法利用LAA Scells(MCG),LAA Scells(SCG)同时和UE进行数据传输。和图4中(b)的显著不同点是：图4中(c)中MeNB/SeNB同频配置了多个LAA辅服务小区，共享利用了所有可能的非授权载波资源，而不需要再内部异频划分。
如果LAA Scells(MCG)和LAA Scells(SCG)被同频部署和配置，它们不能在同一时间段同时和UE进行数据传输，理由同上“UE可能无法彼此识别和 区分信噪和正确接收解码两个数据包…”；由于MeNB和SeNB之间存在X2地面接口，或者如果MeNB和SeNB之间物理距离较近，在空口能够彼此监听到对方正在占用非授权载波资源，因而可以主动回避，保证在某一时间段内只有一个服务eNB节点和UE进行数据传输，因此MeNB和SeNB可以联合地以分时复用的方式利用尽可能多的非授权载波资源。因为MeNB,SeNB能够利用LAA Scells(MCG)和LAA Scells(SCG)资源的前提是：成功通过本地的LBT操作，而是否能成功取决于它们各自周边随机的无线竞争干扰环境，因此协同让MeNB,SeNB同时去做LBT，去抢占尽可能多的非授权载波资源，可以增加非授权载波资源抢占的总成功率。反之如果MeNB，SeNB各自独立地在不同的非授权载波上去竞争抢占资源，则不能最大化非授权载波资源抢占的成功率和利用率。
下面可以用一个简单的数学模型来验证上述结论：
假设非授权频点2上已经有3个相邻竞争节点(包含相邻LAA干扰节点，相邻WLAN干扰节点等)做非授权载波资源的竞争抢占，在非授权频点4上已经有7个相邻竞争节点(包含相邻LAA干扰节点，相邻WLAN干扰节点等)做非授权载波资源的竞争抢占。每个竞争节点在各自频点上能以完全统计公平的方式去抢占和使用对应的非授权载波资源。
按照图4中(b)的LAA异频配置方式，MeNB加入对非授权频点2的竞争，因此可以获得1/4的占用率/使用率；SeNB加入对非授权频点4的竞争，因此可以获得1/8的占用率/使用率；从而总的占用率为1/4+1/8＝3/8＝0.375。这是处于DC工作模式下的UE对可用的非授权载波资源利用率的上限。
按照图4中(c)的LAA同频配置方式，MeNB和SeNB同时加入对非授权频点2的竞争，因此可以获得2/5的占用率/使用率；MeNB和SeNB同时也加入对非授权频点4的竞争，因此可以获得2/9的占用率/使用率；从而总占用率为2/5+2/9＝28/45＝0.622。这是处于DC工作模式下的UE对可用的非授权载波资源利用率的上限。
从上面的示例对比发现：MeNB和SeNB在有协同条件的前提下，联合地同时在同频的非授权载波上做LBT和资源抢占，可以提高处于DC工作模式下UE对非授权载波资源的总体利用率。
为了有效支持DC+LAA同频配置的方案，必须解决如下几个关键的问题：如何进行LAA Scell同频配置激活的协同，如何进行LAA Scell同频运行协同。但是，在相关技术中无法解决上述问题，因此，在相关技术中存在着无法有效支持DC+LAA同频配置的问题。

步骤S504，上述MeNB将一个或多个目标非授权载波频点带宽的信息通知给支持DC的辅基站(SeNB)，其中，该一个或多个目标非授权载波频点带宽的信息用于SeNB选择出给用户设备(UE)服务的非授权载波上配置的授权辅助接入(LAA)辅服务小区(Scell)。
其中，上述的SeNB在接收到MeNB通知的一个或多个目标非授权载波频点带宽的信息后，可以选择与目标非授权载波频点带宽的至少之一相同或重叠的LAA Scell，或者，也可以选择与目标非授权载波频点带宽不相同、不重叠的LAA Scell。通过上述步骤，MeNB在确定了一个或多个目标非授权载波频点带宽后，会将确定的目标非授权载波频点带宽的信息通知给SeNB，从而实现MeNB和SeNB协商确定为UE服务的非授权载波上配置的LAA Scell，解决了相关技术中存在的无法有效支持DC+LAA同频配置的问题，进而实现了MeNB和SeNB协商为终端服务的非授权载波上配置的LAA Scell，达到了有效支持DC+LAA同频配置的效果。
在一个可选的实施例中，上述MeNB将一个或多个目标非授权载波频点带宽的信息通知给SeNB包括：该MeNB通过X2接口的控制消息，将上述一个或多个目标非授权载波频点带宽的信息通知给SeNB。
在一个可选的实施例中，上述方法还包括：MeNB指示SeNB是否允许SeNB进行LAA同频小区的配置。即，MeNB指示SeNB是否允许该SeNB选择和MeNB侧的目标非授权载波频点带宽至少之一相同或重叠的载波频点带宽。

步骤S1：MeNB和UE首先通过各自的RSSI(Received Signal Strength Indication，接收信号强度指示)/RRM(Radio Resource Management，无线资源管理)测量，对所有候选可用的非授权频段内的载波的无线负荷程度和导频信号强度质量做测量评估，基于测量评估的结果，选定最合适的若干个目标非授权载波频点带宽，用于给被服务UE部署/配置/激活对应的LAA Scells(MCG)；此后MeNB可以通过Pcell、Scells(MCG)和LAA Scells(MCG)服务小区集和UE进行上下行数据传输，遵循已有LAA CA工作原理。
步骤S2：类似步骤S1，SeNB和UE也通过各自的RSSI/RRM测量，对所有候选可用的非授权频段内的载波的无线负荷程度和导频信号强度质量做测量评估(由于SeNB和MeNB物理位置不同，因此测量评估的结果可能不同)，基于测量评估的结果，选定含有初始若干个目标非授权载波频点带宽的小区集合Initial_LAA_Scell_Set。
步骤S3：MeNB通过X2接口的控制消息通知SeNB已经选定的LAA Scells(MCG)非授权载波频点和带宽信息，并且通过命令指示：是否允许SeNB进行LAA同频服务小区的配置。
如果允许，则SeNB可以从Initial_LAA_Scell_Set中选择和LAA Scells(MCG)同频或者有部分带宽重叠的若干个目标非授权载波，包括完全或者部分和LAA Scells(MCG)服务小区集重叠的情况。
如果不允许，则SeNB只能从Initial_LAA_Scell_Set中选择和LAA Scells(MCG)完全异频和没有任何带宽重叠的若干个目标非授权载波，此时LAA Scells(SCG)和LAA Scells(MCG)服务小区集没有任何频率部分重叠，这就是传统CA异频的部署配置方式。
SeNB根据上述控制法则从Initial_LAA_Scell_Set筛选确定出子集:Target_LAA_Scell_Set给被服务UE部署/配置/激活对应的LAA Scells(SCG)；此后SeNB可以通过PScell、Scells(SCG)和LAA Scells(SCG)服务小区集和UE进行上下行数据传输，遵循已有LAA CA工作原理。
需要注意的是：LAA Scells(MCG)和LAA Scells(SCG)服务小区集有如下三种基本关系：
关系一：LAA Scells(MCG)和LAA Scells(SCG)内所有服务小区之间完全异频，没有任何频率部分重叠(传统CA异频的部署配置方式，不是本专利要解决的问题)。
关系二：LAA Scells(MCG)和LAA Scells(SCG)内某些服务小区之间有部分异频，但同时有部分同频或者部分频率重叠(属于DC+LAA同频配置运行方式，是本专利要解决的问题)。
关系三：LAA Scells(MCG)和LAA Scells(SCG)内所有服务小区完全一样，全部同频且全部频率重叠(属于DC+LAA同频配置运行方式，是本专利要解决的问题)。
步骤S4：在UE处于DC+LAA同频配置运行的工作模式过程中，当MeNB或者SeNB发现自己某些LAA Scells不合适的时候(比如无线负荷较高或者UE侧导频信号强度质量较差)，可以独立地去激活/删除/自己配置的LAA Scells(MCG)或者LAA Scells(SCG)，但只有当MeNB和SeNB都把某非授权载波频点上的LAA Scells(MCG)和/或LAA Scells(SCG)都去激活/删除之后，UE才完全去激活/删除掉那个物理频点上的LAA Scells。
需要注意的是：从UE角度看来，同一个LAA Scell物理频点，可以在逻辑上，一对多地映射着至少两个辅服务小区，即LAA Scell(MCG)和LAA Scell(SCG)。如果从双连接扩展到更多的连接，那么上述原理一样适用，即同一个LAA Scell物理频点，可以在逻辑上，一对多地映射着更多个辅服务小区。如前所述：在同频配置且激活的LAA Scells(MCG)和LAA Scells(SCG)上，某一时间段内，只能有一个服务eNB节点和UE进行数据的传输，MeNB和SeNB可以联合地以分时复用的方式工作，因此它们之间对非授权载波资源占用状态的协同很重要。如果MeNB和SeNB彼此物理距离较近，且能够监听到对方空口信号发射情况，当某个eNB抢占到非授权载波资源进行数据收发的时候，另外一个eNB通过竞争干扰监听，通常不能成功通过LBT，从而不会同时抢占信道给UE带来收发干扰，因此MeNB/SeNB之间可以通过空口监听自然协同上，这种方式称作基站间的空口自然协同。
如果MeNB和SeNB彼此物理距离较远，不能或者只能微弱地监听到对方空口信号发射的情况，那么只能通过X2接口进行协同，否则可能会发生UE在LAA Scells(MCG)和LAA Scells(SCG)上的数据传输接收的冲突。X2地面接口非理想回程线路(Backhaul)的回传延时在1ms到50ms之间，当系统规定X2回传延时低于某个门限的时候(确保协同的实时性)：
步骤S5：对于LAA同频配置且激活的那些非授权载波，当MeNB/SeNB其中一个成功抢占到本地非授权载波资源，准备对被服务UE进行数据收发的时候，必须通过X2接口的控制消息尽快通知给另外一方。通知的内容至少包含：
当前服务eNB节点即将在哪些非授权载波频点和带宽上(即LAA Scells(MCG)和LAA Scells(SCG)上)成功抢占到资源；
将对哪些被服务UE进行调度和数据传输；
要占用多少时长进行数据传输；
是否允许对方eNB节点继续抢占同非授权载波频点和带宽上的资源。
其中，在MeNB和SeNB彼此物理距离较远，不能或者只能微弱地监听到对方空口信号发射的情况下，当某个eNB抢占到非授权载波资源，且允许对方eNB节点继续抢占同非授权载波频点和带宽上的资源，这种情况下，要 求在同非授权载波频点和带宽上，且在同一段资源占用时间段内，MeNB/SeNB只能对不同的UE进行调度和数据传输，确保同一UE不会同时从MeNB/SeNB接收数据。
步骤S6：被通知方eNB获悉对方服务eNB已经抢占和使用特定的非授权载波资源之后，如果被命令不允许继续抢占同非授权载波频点和带宽上的资源，则规避等待对方服务eNB一段时间，待其使用完毕释放资源之后，再尝试进行非授权载波资源的抢占和使用；如果被命令允许继续抢占同非授权载波频点和带宽上的资源，则仍然可以尝试抢占和使用同频非授权载波资源，但是只能针对对方eNB正在调度的UEs之外的其他UE，进行调度和数据传输，保证同一UE不会同时从MeNB/SeNB接收数据。
实施例一
图19是根据本发明实施例一的DC+LAA同频配置的示意图，在图19所示的示意图中，可以实现如下步骤：
步骤S100：运营商A的MeNB、SeNB和UE都具备LAA CA能力，且MeNB允许在某非授权载波2，4上同时部署两个LAA增容小区，SeNB允许在同频的非授权载波2，5上也部署两个LAA增容小区，当UE进入到前述LAA增容小区共同覆盖区域的时候，MeNB可以为UE配置两个LAA Scells(MCG)和Pcell联合做LAA CA，SeNB可以为UE配置两个LAA Scells(SCG)和PScell联合做LAA CA。UE最大能支持5个异频点载波的聚合。MeNB/SeNB彼此物理距离较远，不能做基站间的空口自然协同，因而必须做本发明实施例的X2接口协同。
步骤S101：MeNB和UE首先通过各自的RSSI/RRM测量，对所有候选可用的非授权频段内载波的无线负荷程度和导频信号强度质量做评估，最终选定非授权载波2的频点带宽为：从5160MHz到5170MHz的10M；非授权载波4的频点带宽为：从5200MHz到5220MHz的20M，用于给被服务UE部署/配置/激活对应的LAA Scells(MCG)。此后MeNB可以通过Pcell和两个LAA Scells(MCG)服务小区集和UE进行上下行数据传输，遵循LAA CA工作原理。
步骤S102：SeNB和UE也通过各自的RSSI/RRM测量，对所有候选可 用的非授权频段内载波的无线负荷程度和导频信号强度质量做评估，选定Initial_LAA_Scell_Set为：非授权载波2的频点带宽为：从5160MHz到5170MHz的10M；非授权载波5的频点带宽为：从5220MHz到5240MHz的20M。
步骤S103：MeNB通过X2接口SeNB Addition Request消息通知SeNB已经选定的目标非授权载波频点和带宽，并且指示允许SeNB进行LAA同频服务小区的配置；进而SeNB确定Target_LAA_Scell_Set为：非授权载波2的频点带宽为从5160MHz到5170MHz的10M；非授权载波5的频点带宽为从5220MHz到5240MHz的20M，于是给被服务UE部署/配置/激活对应的LAA Scells(SCG)。此后SeNB可以通过PScell和两个LAA Scells(SCG)服务小区集和UE进行上下行数据传输，遵循LAA CA工作原理。此时UE一共被配置了5个异频点载波：Pcell@授权载波1，PScell@授权载波3，非授权载波2/4/5。
步骤S104：在UE处于DC+LAA同频运行的工作模式过程中，MeNB一直保持着两个LAA Scells(MCG)处于激活状态；SeNB一直保持着两个LAA Scells(SCG)处于激活状态。UE在非授权载波2的物理频点上，一对二地逻辑映射着LAA Scell(MCG)和LAA Scell(SCG)；UE在非授权载波4的物理频点上，一对一地逻辑映射着LAA Scell(MCG)；UE在非授权载波5的物理频点上，一对一地逻辑映射着LAA Scell(SCG)。
步骤S105：对于非授权载波4和5，由于它们是异频部署配置关系，所以MeNB/SeNB不需要进行资源竞争的协同；对于非授权载波2，当MeNB/SeNB其中一个成功抢占到本地非授权载波资源，准备对被服务UE进行数据收发的时候，必须通过X2接口的LAA状态同步(LAA Status Synchronization)控制消息通知给另外一方。通知的内容包含：
在非授权载波2上，MeNB在LAA Scell(MCG)或者SeNB在LAA Scell(SCG)已经成功抢占到资源；
将对被服务UE(id＝C-RNTI)进行调度和数据传输；
将要占用10ms的时长进行数据传输；
不允许对方eNB节点继续抢占同非授权载波频点2上的资源。
步骤S106：被通知方eNB获悉对方服务eNB已经抢占和使用非授权载波2上的资源之后，规避等待对方eNB使用至少10ms完毕释放资源之后，再尝试进行非授权载波2上的资源抢占和使用。
实施例二
图20是根据本发明实施例二的DC+LAA同频配置示意图，在图20所示的示意图中，可以实现如下步骤：
步骤S200：运营商B的MeNB，SeNB和UE都具备LAA CA能力，且MeNB允许在某非授权载波6，7上同时部署两个LAA增容小区，SeNB允许在同频的非授权载波6，7上也部署两个LAA增容小区，当UE进入到前述LAA增容小区共同覆盖区域的时候，MeNB可以为UE配置两个LAA Scells(MCG)和Pcell联合做LAA CA，SeNB可以为UE配置两个LAA Scells(SCG)和PScell联合做LAA CA。UE最大能支持5个异频点载波的聚合。MeNB/SeNB彼此物理距离较远，不能做基站间的空口自然协同，因而必须做本发明实施例的X2接口协同。
步骤S201：MeNB和UE首先通过各自的RSSI/RRM测量，对所有候选可用的非授权频段内载波的无线负荷程度和导频信号强度质量做评估，最终选定非授权载波6的频点带宽为：从5280MHz到5300MHz的20M；非授权载波7的频点带宽为：从5320MHz到5340MHz的20M，用于给被服务UE部署/配置/激活对应的LAA Scells(MCG)。此后MeNB可以通过Pcell和两个LAA Scells(MCG)服务小区集和UE进行上下行数据传输，遵循LAA CA工作原理。
步骤S202：SeNB和UE也通过各自的RSSI/RRM测量，对所有候选可用的非授权频段内载波的无线负荷程度和导频信号强度质量做评估，选定Initial_LAA_Scell_Set为：非授权载波6的频点带宽为：从5280MHz到5300MHz的20M；非授权载波7的频点带宽为：从5320MHz到5340MHz的20M。
步骤S203：MeNB通过X2接口SeNB Modification Request消息通知SeNB已经选定的目标非授权载波频点和带宽，并且指示允许SeNB进行LAA同频服务小区的配置；进而SeNB确定Target_LAA_Scell_Set为：非授权载 波6的从5280MHz到5300MHz的20M；非授权载波7的从5320MHz到5340MHz的20M，于是给被服务UE部署/配置/激活对应的LAA Scells(SCG)。此后SeNB可以通过PScell和两个LAA Scells(SCG)服务小区集和UE进行上下行数据传输，遵循LAA CA工作原理。此时UE一共被配置了4个异频点载波：Pcell@授权载波1，PScell@授权载波3，非授权载波6/7。
步骤S204：在UE处于DC+LAA同频运行的工作模式过程中，某时刻MeNB对非授权载波6上的LAA Scell(MCG)进行去激活，但是SeNB一直保持着两个LAA Scells(SCG)处于激活状态，因此UE在非授权载波6/7上仍然保持激活。UE在非授权载波6的物理频点上，一对二地逻辑映射着LAA Scell(MCG)和LAA Scell(SCG)；UE在非授权载波7的物理频点上，一对二地逻辑映射着LAA Scell(MCG)和LAA Scell(SCG)。
步骤S205：由于MeNB已经去激活了非授权载波6上的LAA Scell(MCG)，不会给被服务UE进行任何调度和数据传输，因此MeNB/SeNB在非授权载波6上，不需要进行资源竞争的协同；对于非授权载波7，当MeNB/SeNB其中一个成功抢占到本地非授权载波资源，准备对被服务UE进行数据收发的时候，必须通过X2接口的LAA Status Synchronization控制消息通知给另外一方。通知的内容包含：
在非授权载波7上，MeNB在LAA Scell(MCG)或者SeNB在LAA Scell(SCG)已经成功抢占到资源；
将对被服务UE(id＝C-RNTI)进行调度和数据传输；
将要占用6ms的时长进行数据传输；
允许对方eNB节点继续抢占同非授权载波频点7上的资源。
步骤S206：被通知方eNB获悉对方服务eNB已经抢占和使用非授权载波7上的资源之后，仍然允许自己继续抢占同非授权载波频点7上的资源，则仍然尝试抢占和使用同频非授权载波7上的资源，但是只能针对对方eNB正在调度的UE(id＝C-RNTI)之外的其他UE，进行调度和数据传输，保证同一UE不会同时从MeNB/SeNB接收数据。
实施例三
图21是根据本发明实施例三的DC+LAA同频配置示意图，在图21所示的示意图中，可以实现如下步骤：
步骤S300：运营商C的MeNB，SeNB和UE都具备LAA CA能力，且MeNB允许在某非授权载波8上部署一个LAA增容小区，SeNB允许在同频的非授权载波8上也部署一个LAA增容小区，当UE进入到前述LAA增容小区共同覆盖区域的时候，MeNB可以为UE配置一个LAA Scell(MCG)和Pcell联合做LAA CA，SeNB可以为UE配置一个LAA Scell(SCG)和PScell联合做LAA CA。UE最大能支持3个异频点载波的聚合。MeNB/SeNB彼此物理距离较远，不能做基站间的空口自然协同，因而必须做本发明实施例的X2接口协同。
步骤S301：MeNB和UE首先通过各自的RSSI/RRM测量，对所有候选可用的非授权频段内载波的无线负荷程度和导频信号强度质量做评估，最终选定非授权载波8的频点带宽为：从5340MHz到5350MHz的10M，用于给被服务UE部署/配置/激活对应的LAA Scell(MCG)。此后MeNB可以通过Pcell和一个LAA Scell(MCG)服务小区和UE进行上下行数据传输，遵循LAA CA工作原理。
步骤S302：SeNB和UE也通过各自的RSSI/RRM测量，对所有候选可用的非授权频段内载波的无线负荷程度和导频信号强度质量做评估，选定Initial_LAA_Scell_Set为：非授权载波8的频点带宽为：从5340MHz到5350MHz的10M。
步骤S303：MeNB通过X2接口SeNB Modification Request消息通知SeNB已经选定的目标非授权载波频点和带宽，并且指示允许SeNB进行LAA同频服务小区的配置；进而SeNB确定Target_LAA_Scell_Set为：非授权载波8的从5340MHz到5350MHz的10M；于是给被服务UE部署/配置/激活对应的LAA Scell(SCG)。此后SeNB可以通过PScell和一个LAA Scell(SCG)服务小区和UE进行上下行数据传输，遵循LAA CA工作原理。此时UE一共被配置了3个异频点载波：Pcell@授权载波1，PScell@授权载波3，非授权载波8。
步骤S304：在UE处于DC+LAA同频运行的工作模式过程中，某时刻 MeNB对非授权载波8上的LAA Scell(MCG)进行去激活，稍后SeNB也对非授权载波8上的LAA Scell(SCG)进行去激活，因此该被服务UE在非授权载波8上被去激活，之后MeNB/SeNB在非授权载波8上不对UE进行调度和数据传输，直到重新激活服务小区。
步骤S305：对于该被服务UE，由于MeNB/SeNB在非授权载波8上都已经去激活，因此不需要进行资源竞争的协同；需要注意的是：如果MeNB/SeNB同时还服务其他处于DC+LAA同频配置工作模式中的UE，针对那些UE，仍然可能需要进行X2接口的资源竞争协同，因此X2接口的协同操作是以UE为粒度单位操作的。
需要说明的是，上述每个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述模块分别位于多个处理器中。
