Permission required for reproduction or display.IEEE Overview of IEEE Program? Since January 2023, the IEEE Working Group has embarked on development of a new amendment of the IEEE standard (., IEEE ) in order to meet the requirements of ITUR/IMTAdvanced (System Beyond IMT2023, fixed 1Gbps, mobile 100Mbps) for 4G systems while maintaining full backward patibility with the existing mobile WiMAX systems.? The standardization of IEEE and release of mobile WiMAX profile are expected to plete by the end of 2023.? IEEE utilizes OFDMA as the preferred multiple access method in the downlink and uplink to provide the stateoftheart broadband wireless access in the next decade.26 NDSLab Copyright202316m Documentation? Usage Models/Deployment Scenarios System Requirements– A set of possible deployment scenarios and applications of the standard? Evaluation Methodology– A plete set of parameters, models, and methodologies for the linklevel and systemlevel simulations that allow fair evaluation/parison of various technical proposals.– Channels Models: A set of spatial channel model parameters are specified to characterize particular features of MIMO radio channels to be used for simulating technical proposals for the future standard?
