Modulation and Signal Quality in LTE
June 1, 2018

Depending on the modulation technique, each symbol stands for bits and each data point represents a different bit pattern.   QPSK, 16QAM, and 64QAM are used by LTE devices to modulate data and control information. The eNodeB supports all of these modulation techniques for the Down Link direction. However, 64QAM is optional in the Uplink direction. […]
