Abstract: The present invention relates to a communication method for downlink transmission, which is compatible with the existing LTE-based downlink transmission and has low PAPR, for downlink in an LTE-based mobile communication system of which the performance is possibly degraded by the PAPR problem in multi-carrier transmission due to the nonlinearity of a power amplifier in a station including a satellite. Both a terminal using the existing ground LTE chipset and a terminal capable of receiving low PAPR downlink are supported without conflicts. Changes in the existing mobile communication system are minimized economically, and the integration of satellite/ground mobile communication systems are supported.

[Reference numerals] (AA) Start;(BB) Measure the strength of a signal receiving a frame unit upward link;(CC) Determine TPC where a channel expectation value is reflected;(DD) Transmit TPC from a base station to a terminal;(EE) Determine a delay compensation power control value by using the received current TPC and the past TPC;(FF) Reflect the delay compensation power control value to a terminal transmitting power;(GG) Transmit data from the terminal to the base station;(HH) End
