摘　　要：随着5G网络用户的不断增加,4G网络进入资源重构时期,不仅没有新增建设投资,还要不断退频减配。在此双重压力下,如何缓解热点区域的负荷压力,保证网络质量和用户感知,成为运营商的一大难题。在时域和频域资源固定的情况下,本文抓住5G时代终端收发模式上的改变,通过研究和运用空域资源,找寻4G存量资源性能提升方法,着力于解决现有4G网络资源重构中的诸多困难。With the continuous increase of 5G network users, 4G network has entered the period of resource reconstruction, not only there is no new construction investment, but also the frequency reduction and allocation. Under this dual pressure, how to alleviate the load pressure in the hotspot area and guarantee the network quality and user perception has become a big problem for operators. Under the condition of fixed time domain and frequency domain resources, the article seizes the change of the terminal transceiver mode in the 5G era, and fi nds the performance improvement method of 4G stock resources through research and application of airspace resources, and focuses on solving many diffi culties in the reconstruction of existing 4G network resources.
