Description

网络辅助式干扰删除与抑制及其控制方法、装置
本申请要求在2014年09月26日提交中国专利局、申请号为201410505308.1、发明名称为“网络辅助式干扰删除与抑制及其控制方法、装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种网络辅助式干扰删除与抑制(Network Assisted Interference Cancellation and Suppression，NAICS)及其控制方法、装置。
背景技术
随着无线通信技术的迅速发展，第三代合作项目(3rd Generation Partnership Project，3GPP)的版本12(R12)中，提出网络辅助式干扰删除与抑制(Network Assisted Interference Cancellation and Suppression,以下简称NAICS)技术，其原理是，用户设备(User Equipment，UE)配置先进接收机，利用网络侧通知的干扰删除信息，结合自身盲检，对干扰进行有效删除，提升接收性能。
先进接收机有线性的增强的线性最小均方误差-干扰抑制组合(Enhanced Linear Minimum Mean Square Error-Interference Rejection Combining，E-LMMSE-IRC)，非线性的符号级别干扰删除(Interference Cancellation，IC)(Symbol-level Interference Cancellation,SLIC)、最大似然法(Maximum Likelihood，ML)或低复杂度ML(Reduced complexity ML,R-ML)和码字级别IC(Code word level SIC,CWIC)等。其中，E-LMMSE-IRC利用从高层获得的干扰小区导频配置以及预编码矩阵，估计出干扰信道，进而进行干扰抑制合并，提升接收性能；非线性接收机利用干扰相关信息，估计并重构干扰信号，在接收信号中将其删除，大幅提升接收性能。
UE为了进行有效的干扰删除，需要获取的干扰删除信息如下面的表一所示：
表一
Figure PCTCN2015080381-appb-000001
Figure PCTCN2015080381-appb-000002
目前3GPP Rel-12标准化正在讨论这些干扰删除信息的获取方式：高层信令通知或UE盲检。高层信令通知的方式可以降低盲检的复杂度并提高准确性；但是对于用户级的动态参数，高层信令通知的及时性和开销均受限，盲检则成为必不可少的方式。根据干扰删除信息的五种分类，信令设计的原则为：
信令开销较小的小区相关且半静态的干扰删除信息(干扰小区ID、CRS端口数、MBSFN格式等)采用高层信令通知UE；
盲检复杂度可接受的用户相关动态干扰删除信息(调制阶数、DMRS端口数等)依靠UE盲检获取；
盲检复杂度高的用户相关动态干扰删除信息(PA、DMRS VCID等)可以通过设定子集的方式降低复杂度。
但是，对于载波聚合(Carrier Aggregation，CA)场景，UE针对载波聚合的所有成员载波(Component Carrier，CC)都进行NAICS会对UE的处理复杂度造成巨大挑战。而现有技术中，针对CA与NAICS相结合的场景，还没有提出如何降低UE处理复杂度的解决方案。

具体实施方式
本发明实施例提供了一种网络辅助式干扰删除与抑制NAICS及其控制方法、装置，用以针对CA场景，在无需过多高层信令开销以及不浪费UE的载波聚合能力的情况下，降低UE进行NAICS时的处理复杂度。
针对CA与NAICS相结合的场景，容易想到的两种方案例如：
方案一：网络侧不论UE的NAICS能力，对UE能支持的所有CC，均下发NAICS所需的高层信令。UE根据自身的NAICS能力，选择相应的CC进行NAICS。也就是说，网络侧不需要知道哪个CC进行了NAICS。
其中，所述UE的NAICS能力，具体指UE进行NAICS时能支持的CC或band的个数。
此方案对于不能进行NAICS的CC，也下发了高层信令，因此会造成高层信令开销的浪费。
方案二：网络侧根据UE的NAICS能力，为该UE配置相应个数的CC进行载波聚合。
此方案限制了为UE提供载波聚合传输的CC数，浪费了UE的载波聚合能力。
下面结合附图对本发明实施例提供的更为完善的技术方案进行说明。
参见图1，本发明实施例提供的一种网络辅助式干扰删除与抑制NAICS方法，包括步骤：
S101、用户设备UE接收基站发送的干扰删除指示消息，其中包括UE进行NAICS时所针对的成员载波的标识，所述成员载波属于对该UE进行载波聚合传输的成员载波；
由于该干扰删除指示消息中包括UE进行NAICS时所针对的成员载波的标识，从而UE可以有针对性的对成员载波进行NAICS，而不是一定要对所有的成员载波都进行NAICS。
所述基站，可以是演进型基站(Evolved NodeB，eNB)。
S102、所述UE根据所述干扰删除指示消息，对成员载波进行NAICS。
通过该方法，由于UE根据基站发送的干扰删除指示消息，对成员载波进行NAICS，因此针对CA场景，相比前述的方案一和方案二，在无需过多高层信令开销以及不浪费UE的载波聚合能力的情况下，UE进行NAICS处理复杂度得以降低。
较佳地，所述UE接收基站发送的干扰删除指示消息之前，该方法还包括：
所述UE上报进行NAICS时所能支持的成员载波个数给所述基站。即UE上报自身的NAICS能力给基站，若基站预先已经获知了该UE的NAICS能力，则无需UE上报。
较佳地，所述UE接收基站发送的干扰删除指示消息之前，该方法还包括：
所述UE接收所述基站发送的干扰测量通知，并根据该干扰测量通知对每一成员载波进行干扰测量，根据测量结果选择目标成员载波，并向所述基站上报目标成员载波的信息。也就是说，UE可以上报自己根据测量选择出的一个或多个成员载波供基站参考，使得基站可以从UE上报的成员载波中选择成员载波并指示UE对该选择的成员载波进行NAICS。
较佳地，所述根据测量结果选择目标成员载波，包括：
根据每一成员载波的干扰最强的邻区的干扰参数的值的大小，选择预设个数的目标成员载波；或者，
根据每一成员载波的所有干扰邻区的干扰参数的值的总和大小，选择预设个数的目标成员载波；或者，
根据每一成员载波的m个干扰邻区的干扰参数的值的总和大小，选择预设个数的目标成员载波，其中，m为预设的UE针对任一成员载波能删除的干扰邻区数。
例如，UE可以采用上述三种方式，上报干扰最强的M个CC的标识。
较佳地，所述干扰参数为下列参数之一或组合：
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，RSRQ)、接收信号的强度指示(Received Signal Strength Indication，RSSI)。
考虑到Pcell的重要性，较佳地，所述目标成员载波中包括主小区Pcell对应的成员载波。
较佳地，该方法还包括：所述UE获取所述基站针对所述干扰删除指示消息中携带的成员载波的标识所对应的成员载波下发的干扰删除信息；
其中，所述基站针对所述干扰删除指示消息中携带的成员载波的标识所对应的成员载波下发的干扰删除信息，可以携带在基站发送的干扰删除指示消息中，也可以由基站单独发送。
那么，所述UE根据所述干扰删除指示消息，对成员载波进行NAICS，包括：
所述UE根据所述干扰删除指示消息、所述基站下发的所述干扰删除信息，以及所述UE针对所述干扰删除指示消息中携带的成员载波的标识所对应的成员载波盲检得到的干扰删除信息，对所述干扰删除指示消息中携带的成员载波的标识所对应的成员载波进行NAICS。
相应地，在网络侧，参见图2，本发明实施例提供的一种网络辅助式干扰删除与抑制NAICS控制方法，包括步骤：
S201、基站确定用户设备UE进行NAICS时所针对的成员载波的标识，所述成员载波属于对该UE进行载波聚合传输的成员载波；
所述基站可以是eNB。
S202、所述基站向所述UE发送干扰删除指示消息，其中包括所述UE进行NAICS时所针对的成员载波的标识。
通过该控制方法，由于基站发送干扰删除指示消息给UE，使得UE根据该干扰删除指示消息对成员载波进行NAICS，而该干扰删除指示消息中包括UE进行NAICS时所针对的成员载波的标识，从而使得UE可以有针对性的对成员载波进行NAICS，而不是一定要对所有的成员载波都进行NAICS，因此针对CA场景，在无需过多高层信令开销以及不浪费UE的载波聚合能力的情况下，UE进行NAICS处理复杂度得以降低。
较佳地，所述基站向UE发送干扰删除指示消息之前，该方法还包括：
所述基站接收所述UE上报的该UE进行NAICS时所能支持的成员载波个数；
所述基站确定UE进行NAICS时所针对的成员载波的标识，包括：
所述基站根据所述UE上报的该UE进行NAICS时所能支持的成员载波个数，确定UE进行NAICS时所针对的成员载波的标识。
也就是说，基站需要根据UE的NAICS能力，确定UE进行NAICS时所针对的成员载波的标识，而UE的NAICS能力可以是预先在网络侧和UE侧协商确定好的，也可以是由UE后续上报给基站的，若UE的NAICS能力发生了更新，也可以由UE将更新后的NAICS能力上报给基站。
较佳地，所述基站向UE发送干扰删除指示消息之前，该方法还包括：
所述基站根据自身维护的邻区列表向所述UE发送干扰测量通知(此步骤具体可以采用现有技术)，用以指示所述UE根据该干扰测量通知对每一成员载波进行干扰测量；
所述基站接收所述UE上报的目标成员载波的信息，其中所述目标成员载波是所述UE根据该干扰测量通知对每一成员载波进行干扰测量，并根据测量结果选择的；
所述基站确定UE进行NAICS时所针对的成员载波的标识，包括：
所述基站根据所述UE上报的目标成员载波的信息，确定UE进行NAICS时所针对的成员载波的标识。
其中，关于基站根据自身维护的邻区列表向所述UE发送干扰测量通知，介绍如下，
测量启动的触发：
一种方式是触发式：基站给UE配置测量门限，如果满足条件，则根据自身维护的邻区列表向所述UE发送干扰测量通知。
另一种方式也可以是周期性的触发，即按照预设周期，根据自身维护的邻区列表向所述UE发送干扰测量通知。
基站根据自身维护的邻区列表向所述UE发送的干扰测量通知中包含的测量信息有：测量的频点和该邻区列表等。
UE根据该通知需要对邻区进行导频信号强度值的测量等操作。
较佳地，所述干扰删除指示消息中携带的成员载波的标识，包括主小区Pcell对应的成员载波的标识。
较佳地，所述UE上报的目标成员载波的信息，包括目标成员载波的标识及其备选优先级；
所述基站根据所述UE上报的目标成员载波的信息，确定所述UE进行NAICS时所针对的成员载波的标识，包括：
所述基站根据所述UE上报的目标成员载波的备选优先级，选择成员载波，并将选择的成员载波所对应的标识，确定为所述UE进行NAICS时所针对的成员载波的标识。
例如，UE可以上报给基站一个关于目标成员载波的列表，其中包括目标成员载波的标识与备选优先级的对应关系，该列表中成员载波的标识可以是按照备选优先级从高到低的顺序排列好的，便于基站进行选择，基站在选择成员载波时，直接按照备选优先级从高到低的顺序进行选择。
较佳地，所述基站根据所述UE上报的目标成员载波的备选优先级，选择成员载波，包括：
所述基站根据所述UE上报的目标成员载波的备选优先级，选择未被媒体接入控制(MAC)层去激活的成员载波。即对于UE上报的目标成员载波中的某个CC被MAC层去激活的情况，基站可以选择备选优先级较低的下一个CC作为UE进行NAICS所针对的CC。
下面给出一个具体实施例的介绍。
参见图3，本发明实施例提供的一种实现NAICS的流程包括步骤：
S301、UE上报NAICS时能支持的CC个数N。
其中，N小于或等于UE能支持的载波聚合的CC数。
若N在UE和网络侧之间有默认值，则该步骤S301可省略。
S302、eNB根据维护的邻区列表，通知UE进行相应的干扰测量。
S303、UE上报干扰最强的M个CC的标识。
对多个CC，干扰强度判断可以通过如下方式之一进行：
比较干扰最强邻区的RSRP/RSRQ/RSSI大小；
或，比较邻区列表中所有干扰邻区的RSRP/RSRQ/RSSI总和的大小；
或，根据UE能删除的干扰邻区数m，比较最强m个干扰小区的RSRP/RSRQ/RSSI的和。
考虑到Pcell的重要性，除了根据上述干扰强度判断结果选择的CC外，还上报Pcell对应的主载波。
或者，也可以直接从干扰强度出发进行选择，如果Pcell上的干扰较小，也可不上报Pcell对应的主载波。
其中，M>＝N，可以将M个CC的干扰强度排序，上报排序结果。
S304、eNB根据UE上报的M个CC的标识，通知UE进行NACIS的CC标识。
考虑到Pcell的重要性，通知的内容至少包括Pcell。
或者，也可以仅从UE上报的M个CC的标识中选择进行NAICS的CC的标识。
对于UE上报M个CC的排序结果的情况，若某个CC被MAC层去激活的情况，可以从排序结果中顺序选择下一个CC进行NAICS。
最后，eNB通知UE进行NACIS的CC对应的干扰删除信息，并且，UE针对进行NACIS的CC，进行干扰删除信息的盲检，UE结合eNB通知的干扰删除信息和自身盲检获取的干扰删除信息，对eNB通知的CC标识所对应的CC进行NAICS。

较佳地，所述目标成员载波中包括主小区Pcell对应的成员载波。
