Chapter 2. Study of mmWave propagation characteristics and channel modeling
Chapter 3. Methodology for estimation of 5G spectrum requirements
The WRC 2015 approved Resolution 238 [COM6/20] (WRC-15) on the studies on frequencyrelated matters for the IMT identification including possible additional allocations to the mobile services on a primary basis in portion(s) of the frequency range between 24.25 and 86 GHz for the future development of IMT for 2020 and beyond. For the evaluation and development of IMT-2020 (5G) to operate in the frequency range between 24.25 and 86 GHz, there is a need for developing channel models for those bands which are not fully modelled by the existing channel models. As a Korean government 5G project, propagation characteristics and channel modeling study in the mmWave bands have been conducted in ETRI, since 2013. To explore the spatial-temporal characteristics of a wireless channel including the path loss, ETRI developed a wide band channel sounder and performed a field measurement campaign and collecting measured data by transmitting and receiving signals with a 500 MHz bandwidth at carrier frequencies of 28 and 38 GHz.
