Description

一种信道测量方法及装置
本申请要求在2015年2月6日提交中国专利局、申请号为201510065260.1、申请名称为“一种信道测量方法及装置”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
本申请涉及通信技术领域，尤其涉及一种信道测量方法及装置。
背景技术
在MIMO(Multiple-Input Multiple-Output，多输入多输出)传输方式中，基站可以使用多个天线端口与UE(User Equipment，用户设备)之间进行数据传输。在现有通信系统中，基站的天线一般部署成水平排列方式，数量比较少，比如，在LTE(Long Term Evolution，长期演进)系统中，基站天线端口数量现在为1、2、4或8。
基站需要基于UE反馈的下行信道信息进行下行数据调度，因此，UE需要进行信道测量。目前，UE一般基于基站发射的导频信号(如CSI-RS(Channel state information reference symbol，信道状态信息参考信号))来进行信道测量，并反馈下行信道信息，其中包括信道RI(Rank Indicator，轶指示)信息、PMI(Precoding Matrix Indicator，码本索引指示)信息和CQI(Channel Quality Indicator，信道质量指示)信息。
目前，网络侧是以基站为单位进行导频资源配置的，在进行多基站联合传输数据的情况下，网络侧会为每个基站分别配置导频资源，并向UE指示导频资源的配置信息，以便UE准确定位导频资源，进行导频信号测量；该配置信息包括资源索引、传输功率信息、传输周期、以及子帧偏移量。
随着天线技术的发展，天线阵列会由现在的水平排列方式增强到三维及垂直排列方式，基站的天线数量也会因此而急剧增加，比如增加到16、32、64、128、甚至更多；当前的导频资源配置由于是针对1、2、4或8天线端口设计的，就无法再继续适用于这种情况；并且，在当前的导频资源配置中，基站在一个子帧的不同RE(Resource Element，资源单元)上分别发送不同天线端口的导频信号，而一个子帧的一个PRB(Physical Resource Block，物理资源块)对中最多可用于发送导频信号的RE数量是有限的，比如在现有LTE系统中可以用来发送导频信号的RE数量最多为40个，并且，这个数量40是所有基站可以发送导频信号的RE数量的总和；如上面所述，在现有LTE系统中，为每个基站配置1、2、4或8个天线端口，则每个基站最多在一个子帧的一个PRB对上占用1、2、4、或8 个RE。显然，按照现有的配置方式，当基站天线端口数量大于40时，将没有足够的资源支持对基站的各个天线端口的信道测量。
综上，现有的信道测量方案无法满足基站天线端口不断增加的需求。

具体实施方式
在本申请实施例中，当需要为UE配置基站的N端口导频资源时，将其划分为配置L个子导频资源，每个子导频资源占用基站的N个天线端口中的至少一个，并确定L个子导频资源的配置信息；将确定的L个子导频资源的配置信息发送给UE。从而采用本申请实施例，可以在基站天线端口数量超过当前的导频资源配置能力时，将配置一个导频资源划分为配置多个子导频资源，并将多个子导频资源的配置信息通知给UE，这样，UE可以基于L个子导频资源的配置信息，对L个子导频资源进行信道测量，最后基于对L个子导频资源的信道测量结果，生成对基站的N端口导频资源的信道测量结果。采用本申请实施例提供的信道测量方法，不仅可以满足基站天线端口不断增加的需求，而且，可以减少不同基站之间的导频资源的重复性，从而减少不同基站之间的导频信号干扰；另外，一个导频资源占用的天线端口数量越多，对传统不支持导频信号速率匹配的UE的性能影响越大，采用本申请实施例后，将一个导频资源划分为多个子导致资源进行测量，可以减少对UE性能的影响(也即提高UE使用性能)。
下面结合说明书附图对本申请实施例作进一步详细描述。
实施例一
如图1所示，为本申请实施例一提供的信道测量方法流程图，包括以下步骤：
S101：当需要为UE配置基站的N端口导频资源时，为该UE配置L个子导频资源，并确定L个子导频资源的配置信息；其中，每个子导频资源占用所述基站的N个天线端口中的至少一个，且L个子导频资源占用的天线端口数量总和为N；N、L为不小于2的正整数。
在具体实施中，当需要为UE配置基站的N端口导频资源时，根据该N值的大小，选 择配置一个导频资源，还是配置多个子导频资源，比如，若N值小于或等于8，可以按照传统导频资源配置方式，配置一个占用N个天线端口的导频资源，若N值大于8，选择配置L个子导频资源，使每个子导频资源占用所述N个天线端口中的至少一个，不同子导频资源占用不同的天线端口，每个子导频资源占用的天线端口数量小于或等于8，这样，可以基于传统的导频资源配置来配置L个子导频资源。
在配置导频资源(包括所述子导频资源)时，需要配置具体的导频信号、发射导频信号的时频资源等信息。导频信号具体可以是CSI-RS(Channel state information reference symbol，信道状态信息参考信号)。
S102：将确定的L个子导频资源的配置信息发送给所述UE；所述L个子导频资源的配置信息用于所述UE对所述基站的N端口导频资源进行信道测量。
这里，基站可以将确定的L个子导频资源的配置信息通过高层信令发送给UE。这L个子导频资源的集合构成一个N端口导频资源；UE基于L个子导频资源的配置信息，对L个子导频资源进行信道测量，进而得到对N端口导频资源的信道测量结果，然后，将对N端口导频资源的信道测量结果进行信道量化，并反馈量化后的信道测量值。
在具体实施过程中，为了使UE准确定位配置的L个子导频资源，以便完成信道测量，需要向UE发送用于定位L个子导频资源的配置信息。由于L个子导频资源并不是完全相互独立的，而是同属于一个N天线端口的导频资源下的组成部分，因此，在L个子导频资源的配置信息中，还需要指示各个子导频资源之间的关联关系，以便UE将对L个子导频资源的信道测量结果合成为对N端口导频资源的信道测量结果。下面对配置信息作具体介绍。
在本申请实施例中，每个子导频资源的配置信息包括以下信息中的一种或多种：
1)子导频资源的索引l，其中1<＝l<＝L；
2)子导频资源的资源索引(Resource Index)；
3)传输功率信息；
4)传输周期；
5)子帧偏移量(Subframe Offset)；
6)端口号信息；
7)用于指示L个子导频资源的不同天线端口之间具有或不具有QCL(quasi-co-located，准共定位)特性的QCL信息。
可选地，在S101中，确定L个子导频资源的配置信息，包括：
针对L个子导频资源的配置信息中的任一种参数，配置M个子导频资源共用的参数 值，1≤M≤L；或者，分别配置所述L个子导频资源中的每个子导频资源的参数值。
在具体实施过程中，针对所述配置信息中的任一种参数，为各个子导频资源配置的参数值可能为同一个参数值，也可能为各自不同的参数值，还可能部分子导频资源的参数值相同。在具体配置时，针对任一种参数，可以不管各子导频资源之间的参数值是否相同，都单独配置(对应上述分别配置所述L个子导频资源中的每个子导频资源的参数值)。也可以为多个子导频资源共同配置一个参数值，具体地，进行分组配置，为同组的子导频资源配置同一个参数值，为不同组的子导频资源配置不同的参数值(即对应上述配置M个子导频资源共用的参数值)。
可选地，所述配置M个子导频资源共用的参数值，包括：
在所述M个子导频资源的公共配置信息中指示该种参数的参数值，或者，在所述M个子导频资源中的一个子导频资源的配置信息中指示该种参数的参数值。
在具体实施过程中，当配置M个子导频资源共用的参数值时，可以在M个子导频资源的公共配置信息中指示该种参数的参数值，比如，当M＝N时，该公共配置信息实际上也就是一个占用N个天线端口的导频资源(以下简称为N端口导频资源)的配置信息。或者，在M个子导频资源中的一个子导频资源的配置信息中指示该种参数的参数值，比如，当M＝N时，在索引l＝1的子导频资源的配置信息中指示，这时，对于其它子导频资源，默认该种参数的参数值与索引l＝1的子导频资源的参数值相同。
下面针对上述参数分别作介绍。
在上述配置信息中，1)子导频资源的索引l，也即是每个子导频资源在L个子导频资源中的序列号，用于检索对应的子导频资源的配置信息。
2)子导频资源的资源索引，用于指示子导频资源在每个子帧的每个PRB对上占用的RE；这里，每个子导频资源占用的天线端口数量不大于8，在传统导频资源配置能力范围内，因此，子导频资源的资源索引可以采用传统的导频资源的资源索引。在LTE系统中，一个子帧内占用2天线端口的CSI-RS资源有20种(一种CSI-RS资源对应一种RE占用方式)，占用4天线端口的CSI-RS资源有10种，占用8天线端口的CSI-RS资源有5种，该资源索引即用于指示具体配置的是哪种CSI-RS资源，UE在该资源对应的时域/频域的RE上检测导频信号，进行信道测量。
3)传输功率信息，通常可表示为导频信号的功率和PDSCH(Physical Downlink Shared Channel，物理下行共享信道)传输功率的比值。不同子导频资源的传输功率信息可以相同，也可以不同。
在具体实施中，为了提高MIMO系统的灵活性，可以为每个子导频资源单独配置传输 功率。当为L个子导频资源配置相同的传输功率Pc时，可以在L个子导频资源的公共配置信息中指示，这里的公共配置信息也即N端口导频资源的配置信息。
4)传输周期(Periodicity)，以子帧(subframe)为单位；不同子导频资源的传输周期可以相同，也可以不同。
在具体实施中，可以为每个子导频资源单独配置传输周期；也可以在N端口导频资源的配置信息中指示一个各个子导频资源共用的传输周期，或者，只在一个子导频资源(比如索引l＝1的子导频资源)的配置信息中指示该共用的传输周期，UE默认其它子导频资源的传输周期与该子导频资源的传输周期相同。
5)子帧偏移量，用于指示初始子帧偏置(即指示发送导频信号的子帧相对参考子帧偏移几个子帧，该参考子帧可以在系统中另外定义)，与传输周期相结合，可用于指示导频信号发送的子帧；不同子导频资源的子帧偏移量可以相同，也可以不同；为L个子导频资源配置多种子帧偏移量在某些场景下存在部署的必要性，比如：当N＝64时，由于一个子帧的一个PRB对上最多只有40个RE能够用于发送CSI-RS，在端口密度为1RE/PRB对的条件下，必然需要为这L个子导频资源配置至少2种子帧偏移量，并针对子帧偏移量相同的子导频资源，在相同的子帧中发送导频信号，针对子帧偏移量不同的子导频资源，在不同的子帧中发送导频信号。
在具体实施中，可以为每个子导频资源单独配置子帧偏移量，不同子导频资源的子帧偏移量可以相同，也可以不同；也可以在N端口导频资源的配置信息中指示一个各个子导频资源共用的子帧偏移量，或者，只在一个子导频资源(比如索引l＝1)的配置信息中指示该共用的子帧偏移量，UE默认其它子导频资源的传输周期与该子导频资源的子帧偏移量相同；或者，只在一个子导频资源(比如索引l＝1)的配置信息中指示子帧偏移量，UE根据预设的其它子导频资源的子帧偏移量与该子导频资源的子帧偏移量的相对关系(比如其它子导频资源的子帧偏移量比该子导频资源的子帧偏移量大1个子帧)确定其它子导频资源的子帧偏移量，该相对关系也可以作为配置信息指示给UE。
在具体实施中，UE在基于L个子导频资源的配置信息进行信道测量后，还需要基于对L个子导频资源的信道测量结果，生成对N端口导频资源的信道测量结果，在此过程中，需要将不同子导频资源对应的在相同子帧或者最接近子帧上的测量结果划分为一组信道测量结果，通过这样的一组测量结果可以计算得到一个N天线信道矩阵。比如，将一个占用N天线端口的导频资源划分为3个子导频资源，3个子导频资源的传输周期都为5个子帧，子导频资源1和子导频资源2的子帧偏移量都为0，即都在{0，5，10，15，20……}上发送导频信号，子导频资源3的子帧偏移量为2，即在子帧{2，7，12，17……}上发送 导频信号(如图2所示)，则在进行信道测量反馈时，可以将在子导频资源1和子导频资源2的子帧0上的测量结果与在子导频资源3的子帧2上的测量结果作为一组测量结果，将在子导频资源1和子导频资源2的子帧5上的测量结果与在子导频资源3的子帧7上的测量结果作为一组测量结果，……，如此，即为将不同子导频资源对应的在相同子帧或者最接近子帧上的测量结果划分为一组信道测量结果，进行信道计算反馈。这里，不同子导频资源对应的最接近子帧也就是相互之间相差不超过一个传输周期的子帧。
6)端口号信息，用于指示L个子导频资源占用的每个天线端口在N个天线端口中的序列号；在传统的1/2/4/8天线端口的导频资源配置中，每个资源索引对应的各个天线端口的序列号是预先定义好的，因此可以无需另外单独指示端口号信息。在本申请实施例中，由于存在多个子导频资源，UE除需要知道每个子导频资源自己占用的各个天线端口之间的顺序关系外，还需要知道不同子导频资源的天线端口之间的顺序关系。在具体实施过程中，可以在配置信息中指示端口号信息，也可以预先定义端口号的确定方式，比如，该端口号可以是基于各个子导频资源的索引l、各个子导频资源的端口数量确定的。具体地，
可以根据以下公式确定所述端口号信息：
Figure PCTCN2016071345-appb-000009
其中，n表示所述子导频资源中的第n个天线端口，
Figure PCTCN2016071345-appb-000010
为第l个子导频资源的第n个天线端口在所述基站的N端口导频资源中的端口号，MS为第S个子导频资源占用的天线端口数量，α为常数。这里，
Figure PCTCN2016071345-appb-000011
即表示前l-1个子导频资源占用的天线端口数量之和。
需要说明的是，任何以上公式的变形均可在本申请方案的保护范围内，比如，上述端口号是按照索引l呈升序排列，还可以按照索引l呈降序排列等。
当在配置信息中指示所述端口号信息时，可以指示各个子导频资源之间的排序信息，也可以直接指示每个子导频资源占用的各个天线端口的端口号。
7)QCL信息，用于指示L个子导频资源的不同天线端口之间具有或不具有QCL特性，具体地，可以是指示不同子导频资源的天线端口之间具有或不具有QCL特性。在传统的导频资源配置中，UE可以假设一个导频资源中的所有天线端口之间都具有QCL特性。在本申请实施例中，由于存在多个子导频资源，可以有以下几种不同的定义或配置方式：
预先定义所有子导频资源占用的所有天线端口之间都满足QCL特性，这样，可以不再通过配置信息通知UE；
或者，预先定义任一个子导频资源自己所占用的各个天线端口之间都满足QCL特性， 而不同子导频资源占用的天线端口之间都不满足QCL特性；
或者，预先定义任一个子导频资源自己所占用的各个天线端口之间都满足QCL特性，并通过配置信息指示不同子导频资源所占用的天线端口之间满足或不满足QCL特性；
这里，通过配置信息指示不同子导频资源所占用的天线端口之间是否满足QCL特性时，可以采用公共配置信息统一指示QCL信息；比如，可以预设两种QCL信息，在一种QCL信息中，不同子导频资源所占用的天线端口之间都满足QCL特性，在另一种QCL信息中，不同子导频资源所占用的天线端口之间都不满足QCL特性，具体地，可以采用1个比特位来指示，比如采用1来指示不同子导频资源所占用的天线端口之间满足(或不满足)QCL特性，采用0来指示不同子导频资源所占用的天线端口之间不满足(或满足)QCL特性。
通过配置信息指示不同子导频资源所占用的天线端口之间是否满足QCL特性时，也可以针对每个子导频资源单独配置QCL信息；比如，针对任一个子导频资源，可以配置其它一个或多个子导频占用的天线端口与该任一个子导频资源占用的天线端口之间满足QCL特性；再比如，可以预先定义一个子导频资源，对于其它每个子导频资源，通过其它每个子导频资源的配置信息来指示其它每个子导频资源占用的天线端口与该预先定义的子导频资源占用的天线端口之间满足或不满足QCL特性。
上述对QCL的灵活配置可以满足基站配置需求，比如，基站天线阵列通过模拟域波束赋形产生两个波束，占用16个天线端口的基站的导频资源的前8个天线端口与后8个天线端口对应的是不同的模拟域波束，这样前8个天线端口与后8个天线端口之间不存在平均增益(average gain)下的QCL特性，需要配置占用前8个天线端口的子导频资源的各个天线端口和占用后8个天线端口的子导频资源的各个天线端口之间不具有QCL特性，并通知给UE。
