 of SA-preamble at 5 MHz bandwidth [2] CHAPTER 9 The IEEE 802. 16m Physical Layer (Part I) message. In S-SFH SP3, the non-macro BS cell type is partitioned as open and closed subscriber group femto base stations. A total of 16 cases of IDcell partitioning for open and closed subscriber group femto base stations are specified in reference [2], consisting of Cell ID partitions based on 30 sequences, i.e., 10 sequences per segment, in each group. The magnitude of sub-carriers corresponding to the SA-Preamble is amplified. The value of the boosting factor depends on the FFT size and the number of antennas [2]. For a single transmit antenna, the SA-Preamble is transmitted with a magnitude boosting factor of 1.87. The boosted SA-Preamble at kth sub-carrier is denoted as ak = 1.87 Bk where Bk denotes the magnitude of the kth sub-carrier of the SA-Preamble prior to boosting (i.e., +1, -1, or -j). In order to reduce the PAPR of the SA- Preamble sequences, a block cover sequence that is transparent to the receiver is defined and multiplied by each sub-block. Each bit of block cover sequence is mapped to a real number {+1, -1}, and then multiplied by all the sub-carriers in the corresponding sub-block. The SA-Preamble sequences for tone dropping support are obtained by dropping the farthest sub-blocks of the reference bandwidth from the DC sub-carrier on both sides. 9.14 SUPERFRAME HEADERS (BROADCAST CHANNEL) Mobile WiMAX networks may be configured differently according to specific deployment scenarios by various operators (e.g., urban micro-cell, urban macro-cell, and suburban). The system configu- ration information is periodically transmitted by a mobile WiMAX-compliant base station which provides details of operational parameters of the air interface. In the IEEE 802.16-2009 standard, the system configuration information is transmitted by a BS using Downlink Channel Descriptor (DCD) and Uplink Channel Descriptor (UCD) broadcast MAC management messages [1]. The DCD and UCD messages contain system configuration informatio
