Abstract
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a data transmission rate higher than a 4th generation (4G) communication system such as long term evolution (LTE). A user equipment (UE) in a communication system is provided. The UE includes a transceiver, and a controller configured to receive, from a base station, system information including information related to transmission of a random access preamble, and to transmit, to the base station, a physical random access channel (PRACH) including the random access preamble. The PRACH includes at least one primary signal part including a first sequence for measuring a first delay within a symbol, and at least one secondary signal part including a second sequence for measuring a second delay in units of symbols, and a round trip delay (RTD) between the UE and the base station may be determined based on the first delay within the symbol and the second delay in units of symbols.
