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 performed by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, system information including information on a scheduling information list of at least one system information (SI) message and configuration information for an SI request, the configuration information including first information on an SI request period in number of association periods and second nformation on a list of at least one SI request resource, wherein the second information includes information on an index of an association period in the SI request period and information for selecting a physical random access channel (PRACH) occasion within the association period, for each SI request resource, and wherein synchronization signal blocks (SSBs) transmitted in a cell of the base station are mapped at least once to the PRACH occasion within the association period;
- identifying an SI request resource an SI message based on the first information and the second information;
- and
- transmitting, to the base station, an SI request for the SI message using the identified SI request resource,
- wherein the association period includes at least one PRACH configuration period, and a PRACH configuration period includes at least one PRACH occasion,
- wherein, in case that an entry in the list is more than 1, a first entry in the list of the at least one SI request resource corresponds to a first SI message in the scheduling information list for which a status of not broadcasting is set, and a second entry in the list of the at least one SI request resource corresponds to a second SI message in the scheduling information list for which a status of not broadcasting is set.
