1. A method performed by a terminal, the method comprising:
receiving, by the terminal, a System Information Block1 (SIB1), wherein the SIB1 comprises one or more random access channel configuration common (RACH-ConfigCommon) parameters, wherein each of the one or more RACH-ConfigCommon parameters comprises zero or one or more pieces of feature-combination-related information, wherein each of the one or more pieces of feature-combination-related information comprises feature-combination information, wherein the feature-combination information of at least one of the one or more pieces of feature-combination-related information comprises:
a reduced capability (redcap) field;
a small data (smallData) field;
a message3 repetition field; and
a slice-related field, and wherein each of the redcap field, the smallData field, and the message3 repetition field comprises one bit indicating a single value, respectively;
selecting, by the terminal, a piece of feature-combination-related information of the one or more pieces of feature-combination-related information, wherein feature-combination information that comprises at least one feature that triggers a random access is selected based on feature-combination-related information corresponding to feature-combination information that comprises all features triggering the random access not existing; and
performing, by the terminal and based on the piece of feature-combination-related information and first information in a RACH-ConfigCommon parameter, of the one or more RACH-ConfigCommon parameters, that comprises the piece of feature-combination-related information, the random access.
