Description

信道状态信息参考信号的配置方法和装置 技术领域
本申请涉及通信技术，尤其涉及一种信道状态信息参考信号的配置方法和装置。
背景技术
移动管理(Mobility Management，MM)中利用波束赋形可以同时为多个传输模式(Transparent Mode，TM)为TM9或TM10的用户设备(User Equipment，UE)提供专用的业务波束，UE可以基于基站配置的信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)导频测量信道状态信息(Channel State Information，CSI)并反馈。
通常一套CSI-RS导频映射一个固定的波束方向，UE移动时通过切换CSI-RS导频来切换波束方向。但是，随着天线数增多，小区内的波束个数会增加，需要的CSI-RS导频数量也会增多，而CSI-RS导频配置数量变多，会占用更多的时频资源，从而影响小区的频谱效率。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书实施例和权利要求书及附图中的术语“第一”、“第二”等仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元。方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
应当理解，在本申请中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，用于描述关联对象的关联关系，表示可以存在三种关系，例如，“A和/或B”可以表示：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”，其中a，b，c可以是单个，也可以是多个。
图1为本申请信道状态信息参考信号的配置方法实施例的流程图，如图1所示，本实施例的方法可以包括：
步骤101、获取UE数量。
UE为采用TM9或TM10的UE。本申请中网络设备(例如，MM中的基站)为UE配置下行发射波束时，需要参考到TM9或TM10的UE，因此首先要获取这类UE的数量。
步骤102、当UE数量小于或等于设定阈值时，给每个UE配置一个信道状态信息参考信号CSI-RS导频。
通常一个子帧包括14个符号，可以配置的CSI-RS导频数量有限，最多可以配置10个，因此当UE的数量较少时，网络设备才可以实现给每个UE配置一个CSI-RS导频的方案，UE移动时，即使其对应的下行发射波束发生切换，但其测量CSI所使用的CSI-RS 导频是固定不变的，即CSI-RS导频映射的波束方向随UE的位置变化。设定阈值可以根据小区的部署、网优效果、接入的UE数量进行设置，示例性的，设定阈值为6，当UE数量小于6，例如为5时，网络设备给每个UE配置一个固定的CSI-RS导频，一共配置了5个CSI-RS导频，这个数量是远小于最多可以配置的10个CSI-RS导频，5个CSI-RS导频占用的时频资源大大减少，减少了对小区的频谱效率的影响。
网络设备在配置CSI-RS导频时还可以结合UE数量调整CSI-RS导频的周期，即UE数量越少，CSI-RS导频的周期可以越短，UE数量越多，CSI-RS导频的周期可以越长。示例性的，UE数量为5个，根据协议规定CSI-RS导频的周期最短可以配置为5ms，网络设备可以在这5ms周期内给这5个UE配置CSI-RS导频，即，给5个UE分别配置5ms周期内的其中一个子帧上的CSI-RS导频，或者，给5个UE均配置5ms周期内的同一个或几个子帧上的不同的CSI-RS导频，以便于UE可以在其对应的下行发射波束的CSI并反馈。或者，UE数量为60个，CSI-RS导频的周期可以配置为10ms，网络设备可以给这60个UE分别配置10ms周期内的多个子帧上的CSI-RS导频，这样每个子帧内CSI-RS导频占用的时频资源都不会很多，也支持了较多数量的UE。
可选的，在上述示例的两种情况下，由于各个子帧内还有可以配置为CSI-RS导频的时频资源配额，因此网络设备可以将接入的UE中，将没有采用TM9或TM10且请求传输的数据量较大的UE配置为TM9或TM10，再对其采用上述方法配置CSI-RS导频。
本实施例，通过给每个UE配置一个CSI-RS导频，在UE数量较少时，可以减少CSI-RS导频占用的时频资源，进而减少CSI-RS导频配置对小区的频谱效率的影响。
在上述技术方案的基础上，网络设备还可以给小区内的每个波束配置一个CSI-RS导频，即如果UE的数量很多时，给每个UE配置一个CSI-RS导频无法满足系统的通信需求，此时网络设备可以根据现有技术给小区内的每个波束配置一个CSI-RS导频，此处不再赘述。
图2为本申请提供的通信装置200的示意性框图。通信装置200包括获取模块201和配置模块202。
在一个实施例中，通信装置200具有方法实施例中网络设备给UE配置CSI-RS导频的功能。例如，通信装置200可以完全对应图1的实施例中的网络设备。此时，通信装置200的各单元分别用于执行如下操作和/或处理。
获取模块201，用于获取第一用户设备UE数量，所述UE为采用传输模式TM9或TM10的UE；
配置模块202，用于当所述UE数量小于或等于设定阈值时，给每个所述UE配置一个信道状态信息参考信号CSI-RS导频。
在一种可能的实现方式中，所述配置模块202，还用于根据所述UE数量配置所述CSI-RS导频的周期。
在一种可能的实现方式中，所述配置模块202，还用于当所述UE数量大于所述设定阈值时，给小区内的每个波束配置一个CSI-RS导频。
可选地，通信装置200也可以同时具有方法实施例中的其它功能。类似说明可以参考前述方法实施例的描述。为避免重复，这里不再赘述。
