Description

一种信息发送及确定、关系确定的方法及装置 技术领域
本申请涉及但不限于通信领域，尤其涉及一种信息发送及确定、关系确定的方法及装置。
背景技术
信道解调时，如果终端能够预先获取基站到终端之间信道的一些统计特性参数，终端就可以有效的利用这些统计特性参数来提高解调导频的估计准确度，提高接收机性能，有效的压制噪声，并可以将统计特性参数应用于不同的估计算法和接收算法。需要指出的是，只有同一基站发送的导频信号才可以准确测量出上述统计信道特性，也即，这些统计特性参数的测量一般是针对相同基站发出来的导频信号，如信道状态信息测量导频(Channel State Information Reference Signal，简称为CSI-RS)或者小区共有导频(Cell specific Reference Signal，简称为CRS)。
除此之外，基站进行信号发射时，由于器件不可能非常的理想、不引入任何误差，因此实际***中，频偏和时偏问题是不可回避的。一般来说，频偏和时偏校准也可以通过相同基站发送的CSI-RS或CRS进行测量，从而完成对于频偏和时偏的校准。
在长期演进(Long Term Evolution，简称为LTE)/高级长期演进(Long Term Evolution-Advanced，简称为LTE-A)***中，当支持多点传输时，由于数据发送的基站对于终端来说是透明的，并且数据发送的基站可以动态的切换，终端无法准确的获知接收到的数据是由哪一个基站发送的，因此引入了准共位置信息指示(Quasi-Co-Location indicator)的定义和通知信令。
准共位置信息指示，代表了当前数据发送与通知的CSI-RS导频，与专有解调导频信号(de-Modulation Reference Signal，简称为DMRS)发送与通知的CSI-RS导频，是准共位置的，二者发送与通知的CSI-RS导频具有近似相同的信道的大尺度特性，如delay spread,Doppler spread,Doppler shift,average delay，可以将准共位置理解为当前数据与DMRS近似于同一基站发送。在3GPP TS 36.213的标准中，准共位置信息指示是和重映射(RE mapping)的 相关信息进行联合通知的，表1为准共位置指示和数据信道资源单元映射通知信令每个状态的含义。
表1准共位置指示和数据信道资源单元映射通知信令每个状态的含义
Figure PCTCN2016093960-appb-000001
如表1所示，在准共位置指示和数据信道资源单元映射通知信令中，使用了2bit的物理层下行控制信令(Downlink Control Information，简称为DCI)来动态的指示4个参数集(set)，每个set包含一组参数，这一组参数包含了以下多个类别的信息：
-CRS的配置参数信息，包括端口数目以及频域shift的参数。
-多播/组播单频网络(Multimedia Broadcast multicast service Single Frequency Network，简称为MBSFN)子帧配置参数信息。
-零功率(Zero Power，简称为ZP)CSI-RS的参数配置信息。
-数据信道起始符号参数的配置信息。
-准共位置的非零功率(Non-Zero Power，简称为NZP)CSI-RS信息。
可以看出，基站在向终端发送数据的过程中，可以动态的切换发送基站，只需要通过这2bit信令动态的指示上述信息，就可以解决重新映射RE  mapping问题，以及导频与数据传输准共位置变化的问题
在早期版本中，CSI-RS都是非预编码导频，因此基站一般只发送一套CSI-RS。但由于导频和反馈开销的增强，引入预编码CSI-RS后，会出现同一基站发送多个预编码导频的情况，由于不同的预编导频分别对应于不同的预编码权值，这样相当于产生了多个虚拟小区，图1是根据相关技术中在不同预编码导频的情况下产生多个虚拟小区的示意图。
相关技术中有以下几种方式支持不同的预编码导频：
方式1：
表2给出了不同的预编码导频对应于显式的多套不同的导频配置的情况，如表2所示。

由此可知，相关技术中，下行准共位置指示和数据信道资源单元映射通知信令仅仅支持通知一套NZP CSI-RS configuration作为与目前传输的数据信道进行准共位置的绑定，但是，对于方式2、3或4，相关的准共位置信息的通知不能区别对待不同的端口、不同的子帧和不同的子带(频域)，因此这种方法会影响到信道估计性能和接收机性能。并且对于方式1、2、3或4，当一个小区出现多个波束时，会类似于形成如图1所示的多个虚拟小区，此时，相关的2bit下行准共位置指示和数据信道资源单元映射通知信令不再满足需求。
针对相关技术中准共位置信息的通知信令中指示不明确而导致终端获取的信道的大尺度特性不准确的问题，目前尚未提出解决方案。

下面结合具体的实施环境，对本发明实施例的信息发送、确定的方法及装置进行说明。
实施例一
相关技术中，准共位置信息的通知不能区别对待不同的端口、不同的子帧和不同的子带，因此，使用不同的波束进行传输时都必须采用相同的准共位置的NZP CSI-RS configuration进行测量，但实际上不同的波束具有不同的信道特性(逻辑信道，终端只能看到逻辑信道)，因此这种方法会影响到信道估计性能和接收机性能。并且，当一个小区出现多个波束时，类似于形成了如图1的多个虚拟小区，此时，相关的2bit指示信令不再满足需求，在部分情况下可能要支持高达16个及以上的波束的选择。但简单的扩展信令带来的开销并不是一个好的办法。
为了解决相关技术中准共位置信息的通知信令中指示不明确而导致终端获取的信道的大尺度特性不准确的问题，本发明实施例提供了一种准共位置信息的指示方法(即上述信息的发送方法)，包括：基站通过高层信令M个参数集合(parameter Set)，其中，M>＝1，M为正整数，；在每个参数集合中，包含一组准共位置的非零功率CSI-RS导频指示信息；并且，当M>1时，基站还通过物理层控制信令指示终端当前所在子帧的参数集合选择信息。
图8是根据本发明实施例的同一个小区中出现多个不同波束的预编码导频的示意图，如图8所示，当同一个小区中出现了很多个不同波束的预编码导频时，假设这里存在K＝8个波束，每个波束对应一组L＝2port的导频，L为整数，那么终端需要测量K＝8个导频端口组，并选出相应的端口组上报CSI。
此时分为两种情况：
第一种情况：
表6 8×2个port属于同一套NZP CSI-RS导频配置的配置表
Figure PCTCN2016093960-appb-000005
第二种情况：
表7每个波束对应一套NZP CSI-RS导频
CSI-RS配置 包含的端口 波束(Beam)
配置1 15,16, Beam1
配置2 15,16, Beam2
配置3 15,16, Beam3
配置4 15,16, Beam4
配置5 15,16, Beam5
配置6 15,16, Beam6
配置7 15,16, Beam7
配置8 15,16, Beam8
对于第一种情况，相关的准共位置指示的通知是与整个一套NZP CSI-RS导频配置关联的，不区分其中包含的port有不同的delay spread,Doppler spread,Doppler shift,and average delay的情况，因此，如果使用相关的准共位置NZP  CSI-RS信息的通知机制，会出现不够准确的问题，影响性能。
根据本发明实施例，提供一个解决办法是：通知port集合的信息。
例如，在配置8个Set时，可以这样如表8这样配置：
表8对同一套NZP CSI-RS配置信息下的4个波束进行分别配置的指示
Figure PCTCN2016093960-appb-000006
这种方式可以先针对UE配置4个最有可能对应的Beam，再通过DCI进行动态的选择，不同的UE配置不同的Beam，这里的Beam就是指port组。相比于原来的方式，这种方式能够更精确的指示与当前子帧DMRS准共位置的CSI-RS端口组信息，而不是整个NZP CSI-RS包含的所有端口信息，更加准确。
在配置4个Set时，还可以如表9这样配置，这种方法可以包含所有的8个Beam。
表9对同一套NZP CSI-RS配置信息下的8个波束进行分别配置的指示
Figure PCTCN2016093960-appb-000007
Figure PCTCN2016093960-appb-000008
对于第二种情况，根据实施例一中的准共位置信息的指示方法，对第二种情况中的准共位置指示信息可以进行扩展，用于指示与当前DMRS准共位置的更多的端口，在配置4个Set时，还可以如表10这样配置，其中，在表10中，每个准共位置NZP CSI-RS配置ID所指示的一套准共位置的CSI-RS配置中，均包含一个或多个端口组。
表10对8个波束的端口信息进行配置
Figure PCTCN2016093960-appb-000009
实施例二
图9为实现多个波束的CSI-RS导频的示意图一，如图9所示，通过在不 同的子帧位置发送不同的波束，并在不同的位置触发不同的信道量化信息反馈，来以比较灵活的方式支持多个预编码导频。
相关技术通知的是一套周期NZP CSI-RS配置，相当于图9中所有子帧都被认为是与当前数据发送子帧的DMRS具有准共位置的关系，这显然会出现问题。一种解决办法是，在原有的准共位置NZP CSI-RS配置基础上，在每个Set中均增加时域位置指示信息，例如，子帧偏置信息和子帧集合信息等，并通过DCI中的Set选择信令进行选择。
表11为通过子帧偏置信息进行时域位置指示的映射表，如表11所示，其是在原有的参数集合中增加子帧偏置offset的指示。
表11通过增加子帧偏置信息进行时域位置指示
Figure PCTCN2016093960-appb-000010
图10为实现多个波束的CSI-RS导频的示意图二，如图10所示，定义多个窗，在同一个窗内CSI-RS的预编码权值不变，窗间可以发生改变。
为了避免图10中所有子帧都与当前数据发送子帧的DMRS具有准共位置的关系，另一种解决是，在原有的参数集合中增加窗偏置offset的指示，表12为通过窗偏置信息进行时域位置指示的映射表。
表12通过增加窗偏置信息进行时域位置指示
Figure PCTCN2016093960-appb-000011
图11为实现多个波束的CSI-RS导频的示意图三，如图11所示，在时域上的预编码权值可以进行轮循。
同样，为了避免图11中所有子帧都与当前数据发送子帧的DMRS具有准共位置的关系，一种解决办法是：表13为通过增加子帧集合信息进行时域位置指示的映射表，如表13所示，在原有的准共位置NZP CSI-RS配置基础上，在每个Set中均增加子帧集合信息，并通过DCI中的Set选择信令进行选择。
表13通过增加子帧集合信息进行时域位置指示
Figure PCTCN2016093960-appb-000012
实施例三
在配置的***带宽较大时，不同的频域位置上使用的预编码导频可能会发生变化，图12是不同的子带位置具有不同波束的示意图。相关技术中，通 知的是一套周期NZP CSI-RS配置，相当于图12中所有RB/子带发送的CSI-RS都被认为是与当前数据发送子帧的DMRS具有准共位置的关系，这种理解是不准确的，一种解决办法是，在原有的准共位置NZP CSI-RS配置基础上，在每个Set中均增加频域位置指示信息，并通过DCI中的Set选择信令进行选择。
表14是通过通知子带位置进行频域位置的指示，进而不同的子带位置对应着不同的权值。虽然子带1、2、3、4的CSI-RS配置ID都为1，但是每个子带的权值不同，因此，可以实现对于不同的子带位置进行不同的CSI-RS信息配置。
