A method for receiving system information by a mobile station (MS) of a wireless communication system includes receiving a secondary superframe header (S-SFH) change cycle from a base station (BS), and receiving a primary superframe header information element (P-SFH IE) including a first field indicating a change count of a plurality of secondary superframe header subpacket information elements (S-SFH SP IEs) from the base station (BS). Once each of the plurality of S-SFH SP IEs is changed, each of the plurality of S-SFH SP IEs remains unchanged during one or more S-SFH change cycles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus of transmitting and receiving system information in a wireless system","description":"A method and apparatus for transmitting and receiving system information in a wireless communication system are disclosed.
