Abstract: Based on the 1Tx and 2Rx systems working in 3.5GHz frequency and 20MHz bandwidth, the typical beyond 3G (B3G) urban wireless propagation environment of China as well as typical indoor channel propagation environment was studied through a recent indoor and outdoor wireless propagation measurement. The general outdoor model of path loss was verified. A new large-scale fading mode was proposed, which provided reference model for China B3G channel modeling and system design. Important criteria for B3G system evaluation were provided by the measurement, analysis and statistic results of several parameters, namely 1) r.m.s excess delay and max excess delay in both indoor and outdoor scenarios, 2) the lag-time domain and time-frequency domain channel responses, 3) the correlation between different propagation environment in the singular cell, and the antenna correlation.
