基于TDD-LTE系统PDSCH下行功控策略的研究

摘要

通过对TDD-LTE系统中PDSCH信道下行功率分配策略进行分析研究，在不同场景下验证不同的下行功率分配策略对信号电平、信噪比以及下载速率的影响，为现网优化提供理论基础和研究依据。%Downlink power allocation strategy of physical downlink shared channel (PDSCH) in TDD-LTE system was researched. The impacts of different downlink power allocation strategies on signal level, SNR and downlink rate in different scenes were validated. It is able to provide theoretical basis and research foundation to modern network optimization.
