Method and apparatus of transmitting and receiving system information in a wireless system

摘要

A method and apparatus for transmitting and receiving system information in a wireless communication system are disclosed. 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.

1. A method for receiving system information by a mobile station (MS) of a wireless communication system, the method comprising:
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 S-SFH change count and a S-SFH change bitmap from the BS, wherein a value of the S-SFH change count increases only in a superframe where a superframe number (SFN) modulo value of the S-SFH change cycle is a predetermined number, wherein, if the value of the S-SFH change count increases, a value of the S-SFH change bitmap is changed for indicating a changed S-SFH SPx IE, and wherein the changed S-SFH SPx IE is applied to one or more superframes starting from a specific superframe determined by considering a number of changed S-SFH SPx IE transmission.
