DL MIMO efficiency enhancements for LTE

  November 16, 2020    

MIMO is an effective technique to improve spectral efficiency and increase overall network capacity. SRS can be utilized to improve DL MIMO performance, especially for massive MIMO in TDD. In release-16 SRS capacity and coverage are enhanced by introducing more than one SRS symbol in a UL normal subframe and introducing virtual cell ID for SRS. More than one symbol for SRS in a UL normal subframe With...
