FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a wireless communication system. A method for receiving system information by a mobile station (MS) of a wireless communication system includes receiving a secondary super-frame header (S-SFH) change cycle from a base station (BS), and receiving a primary super-frame header information element (P-SFH IE) including a first field indicating a change count of a plurality of secondary super-frame header subpacket information elements (S-SFH SP IE) from the base station (BS). Once each of the plurality of S-SFH SP IE is changed, each of the plurality of S-SFH SP IE remains unchanged during one or more S-SFH change cycles.
EFFECT: reducing mobile station (MS) power consumption and enabling a MS operating in sleep mode to receive system information.
