Abstract: A timing control method performed by a terminal included in a communication network may include: configuring an initial timing reference based on time information obtained from the communication network; receiving a first downlink (DL) signal from a base station; based on the initial timing reference and the first DL signal, obtaining first transmission time information that is information on a timing when the first DL signal is transmitted by the base station and first reception time information that is information on a timing when the first DL signal is received by the terminal; determining a first timing advance (TA) value based on comparison between the first reception time information and the first transmission time information; and adjusting an uplink (UL) transmission timing for the base station based on the first TA value.

Abstract: Disclosed are a communication apparatus and a communication method capable of improving transmitting/receiving frequency efficiency of a satellite signal per bandwidth or spectral efficiency (S.E) per bandwidth by removing and improving a distortion or inter-symbol interference for applying a minimum-mean square error (MMSE) equalizer required to detect a frame synchronization and a modulation code rate in a satellite service for satellite broadcasting or communication under the variable coding and modulation (VCM) or adaptive coding and modulation (ACM) environment.
