QCL configurations in above 6GHz and the necessary RS QCL linkeages 1, 2, 5* 1, 2, 3, 4, 5 Example Config #1 5* - depends on higher layer configuration of CSI-RS resource SS block CSI-RS BM PDCCH DMRS 1, 2, 5 Example Config #2 1, 2, [3, 4], 5 SS block PDCCH DMRS Signalling: RS resource sets and resources configured using RRC QCL parameter(s) between source RS resource (within a set) and target RS resource (within a set) using RRC Needs to include 2 port case 1, 2, 5* Example Config #3 1, 2, 3, 4, 5 SS block CSI-RS BM PDSCH DMRS TCI states 1, 2 may be more general case covering also wide SSB beam and narrow CSI-RS beam Example Config #4 1, 2, 5 1, 2, 3, 4, 5 SS block CSI-RS CSI PDSCH DMRS When SSB has same beamwidth as CSI-RS beam A B B is QCLed to A (configuration in RRC) CSI reporting (with CQI) By DL grant (with MCS) Used QCL association for DMRS defined in CORESET and Search Space configuration that indicates the UE when to assume which QCL association between certain RS and DMRS of PDCCH (RRC/MAC-CE) Example Config #5 1, 2, 3, 4, 5 SS block [1, 2] CSI-RS CSI PDSCH DMRS 5 When SSB has wider beamwidth as CSI-RS beam RRC/MAC-CE configures/updates UE with TCI states table where each TCI state indicates QCL association between certain RS and DMRS of PDSCH. DCI indicates UE which TCI state to use for PDSCH demodulation. CSI-RS BM (1) average delay, (2) Doppler shift, (3) delay spread, (4) Doppler spread, (5) spatial RX parameter(s), (6) average gain
