Abstract
A method of a UE is provided. The method includes receiving, from a base station, configuration information for a system information (SI) request by higher layer signaling, the configuration information including information on a SI request period comprising of a number of association period; identifying information on a SI request resource corresponding to a SI message based on the configuration information, the information on the SI request resource including an index of an association period in the SI request period, information on a random access preamble, and information on a RACH occasion; and transmitting, to the base station, the SI request for the SI message based on the information on the SI request resource.

A method of a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, configuration information for a system information (SI) request by higher layer signaling, the configuration information including first information on an SI request period in number of association periods and second information on at least one SI request resource, each of the at least one SI request resource corresponding to each of at least one SI message, wherein each association period comprises at least one physical random access channel (PRACH) configuration period which includes random access channel (RACH) occasions, and wherein synchronization signal blocks (SSBs) are mapped at least once to the RACH occasions within each association period;
- identifying a resource for requesting an SI message based on the first information and the second information, the second information including an index of an association period of the association periods in the SI request period, information on a preamble start index for the SI message, and information for selecting a RACH occasion within the association period;
- and
- transmitting, to the base station, a message for requesting the SI message using the identified resource.
