Abstract
Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system, such as LTE, and subsequent systems. Provided is a random access preamble transmitting method of a terminal for performing an initial access in a communication system, the method comprising the steps of: acquiring system information from a base station; determining a repetition level of a random access preamble by using the acquired system information; and transmitting the random access preamble with a repetitive frequency corresponding to the repetition level in a transmission resource area corresponding to the determined repetition level.

24. A method for reporting channel state information (CSI) by a user equipment (UE) that operates in at least one subband within a wideband corresponding to a system transmission bandwidth, the method comprising:
-
receiving configuration information for subbands; receiving information related to CSI reporting; measuring CSI of at least one subband indicated by the configuration information for subbands, and determining CSI of the wideband on the basis of the CSI of the at least one subband; and reporting the CSI of the wideband on the basis of the information related to CSI reporting. - View Dependent Claims (25, 26, 27, 28)

29. A method for receiving channel state information (CSI) by a base station that supports a user terminal (UE) operating in at least one subband within a wideband corresponding to a system transmission bandwidth, the method comprising:
-
transmitting configuration information for subbands; transmitting information related to CSI reporting; receiving a CSI report of the wideband from the UE on the basis of the information related to CSI reporting; and scheduling the UE using the received CSI report of the wideband, wherein CSI of the wideband is determined on the basis of CSI of at least one subband indicated by the configuration information for subbands. - View Dependent Claims (30, 31, 32, 33)
