indicated by the BS. Once (Continued) Table 9-14 Contents of Superframe Header [2] Continued Superframe Header Component Periodicity (ms) Parameters Size (Bits) Description the MS has receives the first superframe with resource metric information, it will start to use the resource metric to recommend its preferred partition to the BS in case of mini-band CRU/DRU, or select the preferred sub-bands in case of sub-band CRU subchannelization. Resource metric of frequency partition FP (reuse-1 partition) has fixed value equal to 1. Resource metric of frequency partition FP1 with power boosting is calculated as Resource_Metric_FP1 = 3- Resouce_Metric_FP2-Resouce Metric_FP3. The number of bits depends on the value of FPCT and the frequency partition size parameters. loT Correction Value for UL 10-bit loT value is used to support Power Control the correction of 5 loT values (loT_Sounding, loT_FP0, loT_FP1, loT_FP2, loT_FP3) defined in AAI_ULPC-NI message (UL Noise and Interference Level Broadcast message), each 2 bits are expressed as the correction value: ObOO: +1 dB; Ob01: +0.5 dB; Ob10: 0 dB; Ob11: -0.5 dB. The correction value is accumulated on loT values from the latest AAI_ULPC-NI message until the new AAI_ULPC-NI message is received and processed. Number of Distributed LRUs for The number of UL feedback UL Feedback Channel per a UL channels according to AAI Subframe UL_FEEDBACK_SIZE. Number of BS Transmit Number of BS transmit antennas: Antennas ObOO: 2 antennas; 0b01: 4 antennas; Ob10: 8 antennas; Ob11: reserved. SP Scheduling Periodicity The S-SFH sub-packet IEs (i.e., Information S-SFH SP1 IE, SP 2 IE and SP3 IE) are transmitted by the BS at the scheduled times with different periodicity (i.e., TSP1 < TSP2 < TSP3). HO Ranging Back-off Start Initial back-off window size for MS performing initial ranging during HO process expressed as a power of 2 (0 n < 15). HO Ranging Backoff End Final back-off window size for MS performing initial ranging during HO process expressed as a power of 2 (0 < n < 15). Initial Rangin
