As the standardization of 5G New Radio (NR) systems operating in micro- and millimeter-wave frequency bands is over, scientific and industrial communities have begun to address the question of what 6G communications systems might or should be. While technological specifics are still in their early development phase, there is a common agreement that these systems will utilize the lower part of the terahertz band, namely, 100-300 GHz. This band poses a number of specific challenges for system designers, including the effects related to channel characteristics and the conceptually new requirements for electronics. This paper aims to report the current state-of-the-art channel characterization and communications system design. With respect to the former, we consider dynamic human body blockages and micromobility impairments. For the latter, we mainly concentrate on the physical layer devices for direct conversion schemes and the design of the so-called reconfigurable intelligent surfaces that will potentially serve as a cost-efficient blockage mitigation technique.

На текущий момент стандартизация систем 5G Новое Радио, работающих в диапазоне частот микро- и миллиметровых волн, завершена. Исследовательское сообщество, стандартизищирующие организации и производители оборудования начинают решать вопрос о том, какой может или должна быть система связи 6G. Хотя технологические особенности все еще находятся на ранней стадии разработки, существует общее мнение, что эти системы будут использовать нижнюю часть терагерцового диапазона, 100-300 ГГц. Этот диапазон создает ряд специфических проблем для разработчиков систем, включая эффекты, связанные с характеристиками канала, а также концептуально новые требования к электронике. Целью данной статьи является обзор текущего состояния исследований в области определения характеристик каналов и проектирования систем связи. В отношении первых мы будем рассматривать динамическую блокировку путей распрострарения сигнала телом человека и эффект микромобильность. С точки зрения системного уровня, мы концентрируемся на устройствах для схем прямого преобразования и разработке так называемых реконфигурируемых интеллектуальных поверхностей, которые потенциально могут служить экономичным методом устранения блокировок.
