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...

 Rel-14 NR study showed that duplexing flexibility with cross-link interference mitigation shows better user throughput compared to static UL/DL operation or dynamic UL/DL operation without interference mitigation in indoor hotspot (4GHz and 30GHz) and urban macro scenarios (4GHz and 2GHz). Furthermore, semi-static and/or dynamic DL/UL resource assignments should also consider coexistence issues...
