containing the system configuration information can be acquired, this would enable the MS to make a decision for attachment to the BS without acquiring and decoding the legacy Frame Control Header (FCH) and DL MAP and waiting for arrival of the DCD/ UCD messages (DCD/UCD messages are transmitted every few hundred milliseconds). This modi- fication would further result in power saving in the MS due to shortening and simplification of the initialization procedure, thereby facilitating cell selection or re-selection. In the IEEE 802.16m, the Superframe Header (SFH) carries essential system parameters and configuration information. The SFH consists of two components, i.e., Primary Superframe Header (P-SFH); and Secondary Superframe Header (S-SFH). The primary superframe header is transmitted every superframe, whereas the secondary superframe header is transmitted every few superframes. The primary and secondary superframe headers are located in the first subframe within a superframe and are time-division-multiplexed with the secondary advanced preamble. The superframe header occupies a narrower bandwidth relative to the system bandwidth (i.e., 5 MHz). The primary super- frame header is transmitted using a predetermined modulation and coding scheme. The secondary superframe header is also transmitted using a predetermined modulation scheme, while its repetition factor is signaled via primary superframe header. The primary and secondary superframe headers are transmitted using two spatial streams and space-frequency block coding to improve coverage and reliability. The MS is not required to know the antenna configuration prior to decoding the primary superframe header. The information transmitted in the secondary superframe header is divided into three sub-packets. The secondary superframe header Sub-Packet 1 (SP1) includes information required for network re-entry. The secondary superframe header Sub-Packet 2 (SP2) contains infor- mation for initial network entry. The secondary superframe header Sub-Packet 3 (SP3) con
