【正文】 Channel model for IMTAdvanced ?Contractual Date of Delivery to the CEC: 30/09/2022 ?Participants: EBITG, TUI, UOULU, CU/CRC, NOKIA ?Estimated person months: 62 ?WINNER II channel models for link and system level simulations. ?Both generic and clustered delay line models are defined for selected propagation scenarios. ? The channel models are based on a literature survey and measurements performed during this project. Channel realizations are generated by summing contributions of rays with specific channel parameters like delay, power, angleofarrival and angleof departure. Different scenarios are modeled by using the same approach, but different parameters. A number of rays constitute a cluster. In Winner II we equate the cluster with a propagation path diffused in space, either or both in delay and angle domains.
