哈尔滨移动TDD-LTE面临深度覆盖的瓶颈,市区楼宇密集,居民区建站阻挠多,造成室内深度覆盖的难题。TDD-LTE小区边缘覆盖和SINR下降,不利于VOLTE的部署。针对深度覆盖不足问题提出“软劈裂”多频共天馈小区的方案来提升MR覆盖率,提升LTE网络质量与用户感知。 Harbin mobile TDD-LTE faces the bottleneck of deep coverage, dense urban buildings, building blocks in residential areas obstruct more, resulting in indoor depth of the problem. TDD-LTE cell edge coverage and SINR decline, is not conducive to the deployment of VOLTE. Aiming at the problem of insufficient coverage, a scheme of “soft splitting” multi-frequency co-fed cell is proposed to improve MR coverage and improve LTE network quality and user perception.
