摘　　要：NSA网络架构模式下,5G语音业务承载于4G锚点网络上。4G/5G双连接模式的网络架构,使得终端语音业务上行功率较传统4G语音业务上行功率损失3 dB,从而影响小区边缘NSA用户语音业务体验。本文研究了几种基于NSA终端上行功率分配的策略及其特点,以提升NSA终端上行覆盖性能和用户感知体验。In non-standalone network architecture mode,5G voice service is carried on 4G anchor network.The network architecture of 4G/5G dual connection mode makes the uplink power of terminal voice service lose 3 dB compared with the traditional 4G voice service,which affects the voice service experience of non-standalone users at the cell edge.This paper studies several strategies and characteristics of uplink power allocation based on non-standalone terminal,in order to improve the uplink coverage performance and user perception experience of non-standalone terminal.
