Abstract: Disclosed are a method and an apparatus for determining a Guard Period (GP) in a Time Division Duplexing (TDD) system. A communication method based on Time Division Duplexing (TDD) includes: determining, by a base station, a guard period based on information on a distance between user equipment and the base station; and performing, by the base station, downlink transmission to the user equipment based on the determined guard period, wherein the guard period is determined based on one of a default guard period mode, a reduced guard period mode, and a zero guard period mode, and the reduced guard period mode is a mode for setting a reduced guard period, which is shorter than the default guard period set based on the default guard period mode, and the zero guard period mode is a mode for setting a length of the guard period to 0.

Abstract: Provided is a terahertz health checker. The terahertz health checker includes a terahertz wave transmitter generating terahertz waves in a terahertz band, a lens outputting the terahertz waves and receiving terahertz waves reflected from the outputted terahertz waves, an imaging chip connected to the lens, detecting the received terahertz waves, and generating a digital image signal based on the detected terahertz waves, a readout circuit reading out the digital image signal, and a transceiver outputting the read-out digital image signal to the outside.
