RUs (PRUSB) and mini-band PRUs (PRUMB). The set of PRU SB and PRUMB are numbered from 0 to (LSB - 1) and 0 to (LMB - 1), respectively. The uplink mini-band permutation maps the set of PRU MB to the Permuted PRUMBS (PPRUMB) to ensure frequency diversity is sufficiently utilized in each frequency partition. The PRUSBS and PPRU MBS are allocated to one or more frequency partitions. By default, only one frequency partition is present. The maximum number of frequency partitions is four and the uplink frequency partition configuration information is transmitted via the S-SFH sub-packet 1 using Uplink Frequency Partition Configuration (UFPC), whose value depends on the system bandwidth. The Frequency Partition Count (FPCT) parameter defines the number of frequency partitions. The Frequency Partition Size (FPSi) defines the number of PRUs allocated to the ith frequency partition (i.e., FPi). The FPCT and FPSi parameters are determined from the UFPC, based on predefined mappings given in reference [2]. The Uplink Frequency Partition Sub-band Count (UFPSC) parameter defines the number of sub-bands allocated to FPi (for i >0). If UFPC = 0, then UFPSC is set to 0. The PRUFP is mapped to a logical resource unit. Additional PRU and tile permutations are limited to the PRUs within a frequency partition. The mapping and permutation of CRUs and DRUs in each partition are performed on a sector- specific basis. Let LSB-CRU-FPi and LMB-CRU-FPi denote the number of allocated sub-band CRUs and mini-band CRUs for FPi (i > 0). The total number of allocated CRUs in a unit of sub-bands within FPi (for i 0) is given by uplink CRU allocation size UCAS. The number of sub-band and mini-band CRUs in FP0 is given by UCASS and UCAS MBO in integer multiples of sub-band and mini-band, respectively. The value of UCASSBO is broadcast in the S-SFH for FP0. An uplink mini-band CRU CHAPTER 9 The IEEE 802. 16m Physical Layer (Part I) allocation size UCAS MBO parameter is sent in the S-SFH only for partition FP0 depending on system bandwidth. The number
