1. A method for operating a base station for transmitting system information in a wireless communication system, the method comprising:
- transmitting system information for a first periodicity and a second periodicity which is a multiple of the first periodicity;
transmitting a first subpacket according to the first periodicity and a first offset; and
if a modulo operation result of a superframe number of a superframe with the second periodicity is equal to a second offset, transmitting a second subpacket according to the second periodicity, at the superframe,wherein the system information is carried in a plurality of subpackets comprising the first subpacket and the second subpacket,wherein the second offset is identified as being equal to a value which is smaller than the first periodicity if the first offset is zero, andwherein the second offset is identified as being equal to the first periodicity if the first offset is not zero and smaller than the first periodicity.

Abstract
To transmit and receive system information of a base station in a broadband wireless access system, operations of the base station include determining transmission periodicities of a plurality of system information subpackets periodically transmitted in a periodicity of two or more superframes, determining transmission offsets of the subpackets based on the transmission periodicities using a predefined rule for determining a transmission periodicity and a transmission offset, and transmitting the subpackets respectively according to the transmission periodicities and the transmission offsets.
