Problems solved by technology

However, if there is a frame for P-SFH transmission in the sleep window of the MS, the MS cannot receive P-SFH
[0025] According to the above prior art, MS needs to decode P-SFH every superframe to determine whether S-SFH SP IE is changed, which leads to increase of MS power consumption

Embodiment Construction

[0066] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. The detailed description, given below with reference to the accompanying drawings, is for explaining exemplary embodiments of the present invention, rather than showing the only embodiments that can be implemented according to the present invention. The following detailed description includes specific details in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without such specific details. For example, the following description will focus on the mobile communication system used as the 3rd Generation Partnership Project 2 (3GPP2) 802.16 system, but the present invention is not limited thereto and the rest of the present invention except the unique characteristics of the 3GPP2 802.16 system may Applied to ot...

Abstract

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.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly to a method and apparatus for transmitting and receiving system information in a wireless communication system. Background technique [0002] The superframe header (SFH) will be briefly described below. [0003] The base station (BS) sends system information to the mobile station (MS) through the SFH. SFH is located in the first subframe included in one superframe. SFH is divided into Primary SFH (P-SFH) and Secondary SFH (S-SFH). [0004] Table 1 shows P-SFH Information Elements (IEs). [0005] Table 1 [0006] [Table 1] [0007] [0008] Table 2 shows the S-SFH IE format. S-SFH sends actual system information. System parameters and system configuration information transmitted through S-SFH are classified into S-SFH SP1 IE, S-SFH SP2 IE, and S-SFH SP3 IE. The S-SFHSP1 IE includes network reentry information. S-SFH SP2IE includes initial network entry an...
