Description

上行功率控制方法和装置 技术领域
本发明实施例涉及通信技术，尤其涉及一种上行功率控制方法和装置。
背景技术
多天线多输入多输出(Multiple Input Multiple Output，简称MIMO)技术已经被广泛地应用在无线通信系统中来提高系统容量和保证小区的覆盖，如长期演进(Long Term Evolution，简称LTE)系统的下行采用了基于多天线的发送分集，开环/闭环的空分复用和基于解调参考信号(Demodulation Reference Signal，简称DMRS)的多流传输，其中基于DMRS的多流传输是LTE高级演进(LTE-Advanced，简称LTE-A)系统以及后续系统的主要传输模式。为了进一步提高多天线系统的性能，版本Rel-12标准中正在研究二维的天线配置，即天线同时放在水平和垂直方向上，从而可以同时进行水平和垂直方向上的波束赋形，被称为三维波束赋形，图1A为二维天线配置的示意图。
此外，当前Rel-12标准在引入二维天线配置的同时还引入用户设备的三维分布，即用户设备除了可以在水平面分布外，还可以在垂直向如1到8层的高楼内分布，每用户设备的位置坐标既包括水平向也包括垂直向。当假定用户设备高度为1.5米，每楼层高度为3米时，1到8层的用户设备高度范围从1.5米到22.5米。在存在更高楼(如楼高为20到30层)的场景下，最高楼层的用户设备高度可达88.5米。而在Rel-12标准研究的3D城市宏蜂窝(Urban Macro，简称UMa)和3D城市微蜂窝(Urban Micro，简称UMi)场景下，基站和用户设备UE的每条链路上的路径损耗与用户设备高度成正比，从而最高楼层用户设备和1层或地面用户设备的路径损耗相差几十个dB。基站和用户设备链路上的大尺度衰落除路径损耗项外还包括阴影衰落，穿透损耗，天线增益等项。但1层楼用户设备和最高楼层用户设备在上述这些项上的差别远没有路径损耗带来的差值大。图1B为3D UMi场景下的8层楼用户设备和1层楼用户设备的大尺度衰落分布图，图1B中1层楼用户设备被一个指向12度的下倾角的预编码波束服务，而8层楼的用户设备被一个指向-6度的上倾角的预编码波束服务，从图 1B中可看到8层楼用户设备和1层楼用户设备的最小大尺度衰落值相差10-20dB左右。
现有技术中存在的问题是，当前LTE标准中的上行功率控制机制是一种基于对大尺度衰落进行补偿的机制，所述大尺度衰落相关的功率控制参数和调整值均为小区级别的，无法实现对小区内不同用户或用户组的大尺度衰落补偿和相应的功率控制，因此针对3D新场景使用当前上行功率控制方法存在不准确的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
图2为本发明上行功率控制方法实施例一的流程图。本实施例的执行主体可以为用户设备，本实施例的方案应用在网络设备和用户设备之间，进行上行功率控制。如图2所示，本实施例的方法可以包括：
步骤201、接收网络设备配置的测量导频，测量导频对应一个预编码矩阵信息。
步骤202、接收网络设备配置的功率控制参数，功率控制参数与配置的测量导频对应；功率控制参数用于用户设备UE控制其在服务小区上的发射功率。
具体来说，用户设备UE接收网络设备配置的测量导频，所述测量导频对应一个预编码矩阵信息，并且接收网络设备配置的功率控制参数，所述功率控制参数与所述测量导频对应，UE根据所述功率控制参数控制其在服务小区上的发射功率。
可选地，所述功率控制参数与配置的所述测量导频对应，包括：接收到相同测量导频配置的UE的功率控制参数配置相同。
可选地，所述功率控制参数包括：所述UE的目标接收功率，路损补偿因子和传输格式补偿项。
其中，上述功率控制参数可以是基站用组播的无线网络临时鉴定RNTI或用户特定的RNTI方式下发下来的。
本发明实施例针对3D新场景或高频下每小区的不同用户设备组有不同大尺度衰落的特点，可以进行每小区的用户设备分组功率控制，即相当于每小区进一步被分成几个“虚拟小区”，其中，每个“虚拟小区”对应一组用户设备。如小区内所有位于1层楼或地面的用户设备为一组，此组用 户设备对应一套指向波束12度的测量导频配置，而所有位于8层楼的用户设备为一组，此组用户设备对应一套指向波束-6度的测量导频配置。因此一套测量导频配置下的用户可归为一组，对应一个“虚拟小区”。每个“虚拟小区”有独立的“小区”级大尺度功率控制参数。所述“小区”级大尺度功率控制参数指的是功率控制机制中所有大尺度相关的小区特定功率控制参数。
本发明实施例上行功率控制方法和装置，通过接收网络设备配置的测量导频，所述测量导频对应一个预编码矩阵信息；接收网络设备配置的功率控制参数，所述功率控制参数与配置的所述测量导频对应；所述功率控制参数用于用户设备UE控制其在服务小区上的发射功率，实现了基于对大尺度衰落进行补偿的上行功率控制机制，所述大尺度衰落相关的功率控制参数和调整值均为用户设备组级别的，即对应不同的测量导频，功率控制参数不同，提高了上行功率控制的准确性，解决了现有技术中针对3D新场景使用当前上行功率控制方法存在不准确的问题。
