摘　　要：LTE 2×1T1R RRU技术的优势包括提高主设备和光纤资源的利用率、减少功耗、提升用户数容量以及节能减排等;同时也存在一些短板,包括无法使用MIMO导致峰值速率降低和前向覆盖功率略有降低等。从LTE2×1T1R RRU技术的优劣势出发,根据不同场景的个性化需求,对该技术的应用场景作了细分,同时对各细分场景使用LTE 2×1T1R RRU技术的关注点提出了建议。The advantages of LTE 2×1T1R RRU technique include utilization improvement of main equipment and optical fiber resources, power reduction, user capacity increase and energy saving. However, some disadvantages are attached to the technique such as peak rate reduction resulted from no MIMO technique and forward coverage power reduction. In view of these disadvantages, the application scenes of the technique are precisely classified according to the demands of different scenes, while some recommendations on the application focus of LTE 2×1T1R RRU technique are presented.
