Key technologies and network planning strategies of LTE-U

LTE operation in unlicensed band has the potential to offer significantly better network capacity through carrier aggregation with licensed LTE. Operators and equipment manufacturers paid attention toSLTE-U hoping it would relieve the increasingly serious shortage of spectrum. Considering the influence to network planning by LTE-U, this article firstly researched the key technologies of LTE-U, secondly analyzed on the spectrum allocation, network standard choice, carrier aggregation schemes, network deployment, and interference avoidance of LTE-U. And then this article put forward instructive strategies of LTE-U network planning aiming to improve the quality and network construction efficiency of LTE for CMCC.
