道路测试指标是运营商衡量TD-LTE网络覆盖能力、用户感知以及系统容量的主要手段。以提高TD-LTE网络道路测试指标为目的，在D频段和F频段上对中心城区、郊区和农村3个不同场景条件分别进行实验测试对比，得出最优下行CRS功率PA和PB参数配置。在保证覆盖率的前提下，降低了下行干扰，提高了下行吞吐率，从而提升系统容量和用户感知度，以达到优化目的。

Road test indicator is the main way to evaluate TD-LTE network coverage, user perception and system capacity for operators. In order to improve road test indicator, experimental tests were compared in three scenarios of urban, suburban and rural areas at D and F bands, and parameter conifgurations of optimal downlink CRS power PA and PB were derived. On the premise of guaranteeing coverage, the optimization goal was achieved that downlink interference was reduced, downlink throughput was improved, system capacity and user perception were enhanced.
