Abstract: The present disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting higher data rates after a 4th generation (4G) communication system such as long term evolution (LTE).
According to an embodiment of the present disclosure, a method of identifying, by a base station (BS), a line-of-sight (LOS) channel in a wireless communication system may include: receiving, from a user equipment (UE), a signal for measuring a channel in each of multiple bands; determining, based on the signal, whether the channel is an LOS channel in each of the multiple bands; in response to a determination that the LOS channel exists in each of the multiple bands, identifying the channel as the LOS channel; and transmitting data to the UE, based on the LOS channel.-

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.
