Abstract

一种上行功率分配方法、装置及移动终端，其中，该方法包括：移动终端获取每条通信连接中的下行信道的传输质量；在该移动终端与基站之间建立有两条或两条以上的通信连接的情况下，该移动终端根据每条通信连接中的下行信道的传输质量，分配该移动终端在每条通信连接上的发射功率。

Description

一种上行功率分配方法、装置及移动终端 技术领域
本申请涉及但不限于无线通信技术领域。
背景技术
双连接(Dual Link)指的是用户设备(User Equipment，简称为：UE)同时使用由非理想回传(non-ideal backhaul)连接的两个演进型基站(evolved Node B，简称为：eNB)的资源，UE可以同时使用主基站(MeNB)和从基站(SeNB)中的多个服务小区(Serving Cell)中的资源进行数据收发，能够有效提高单用户吞吐量。
双连接中，UE可以将宏基站作为MeNB，将微基站作为SeNB，双连接与UE和微基站单连接的方式相比，可以在有效减少切换次数的同时，改善微基站的小区的边界性能。
在双连接的应用场景中，UE面临两种连接同时保持的情况下，存在如何有效的分配UE的发射功率的问题。相关技术中，功率分配原则是，距离越远的，分配给的发射功率越大，但是如果按照上述方式分配发送功率，就是做了一个最低的功率配置，使得短板效应比较明显，因为距离的远近并不一定能够真实的反映出传输信号的质量，且距离越远，信噪比越小，将较多的发射功率分配给信号质量不太好的信道，反而会降低系统的通信容量，降低通信效率。

本发明实施例还提供一种移动终端，为执行本发明实施例提供的上行功率分配方法的实体装置，该移动终端可以包括图3和图4所示任一实施例中的上行功率分配装置。
本发明实施例还提供一种上行功率分配方法，在上述实施例的基础上，以双连接为例进行说明，介绍本发明的应用实例。
本发明实施例是采用注水算法的原理，根据信道状况对发送功率进行自适应分配，通常是针对信道状况好的通信连接，多分配发射功率，针对信道状况差的通信连接，少分配发射功率，从而最大化传输速率，实现为功率的“注水”分配。
在功率分配的问题中，只有满足注水算法的原理时，才能达到信道容量最大化。而信噪比能够反映信道状况的好坏，也就是说，信噪比大的信道分得的发射功率份额多，信噪比小的信道分得的发射功率份额少。
基于以上考虑，使用注水算法进行功率分配的方式，即是在双连接中寻求一种传输效率最大化的发射功率分配方式。移动终端与两个基站分别建立一条通信连接，该移动终端对上述两条通信连接中的发射功率的分配过程可以包括如下步骤：
步骤1，移动终端根据测量得到通信连接1的下行信道的信噪比(Signal to Interference plus Noise Ratio，简称为：SINR)记为sinr_1，根据测量得到的通信连接2的下行信道的SINR记为sinr_2。
步骤2，移动终端的上述两条通信连接可以使用的总发射功率记为Pmax，此时，根据每个基站对移动终端的功控过程得到通信连接1需要的发射功率记为P_1，通信连接2需要的发射功率记为P_2。
步骤3，如果P_1+P_2>Pmax，那么就需要重新设置发射功率，设置方式如下：
P_1＝Pmax×sinr_1/(sinr_1+sinr_2)；
P_2＝Pmax×sinr_2/(sinr_1+sinr_2)。
步骤4，按照以上步骤分配移动终端分别在两条通信连接中的发射功率，就可以达到传输效率最大化的目的。
同时需要指出的是，如果不按照这种方式，那么就不能得到双连接下的最大功率效率，也就不能得到最符合功率配置的流量。
本发明实施例提供的功率分配方法具有如下特点：
(1)、本发明实施例中的功率分配方法能实现移动终端上行流量的最大化，提高上行频谱效率。
(2)、本发明实施例中的功率分配方法不仅限于双连接的应用场景，可以扩展到多路连接的应用场景中；从而实现多路的连接功率的传输效果最大化。
