source in a number of contiguous LRUs in the frequency-domain over the subframe and the index of the LRU from which the scheduled allocation is measured. The contiguous LRUs can be constructed from distributed LRUs, mini-band LRUs, or sub-band LRUs. The mapping between LRU and physical PRU indices is derived as follows. For each frequency partition i, let TCLRUi, denote the total number of contiguous LRUs and distributed LRUs up to and including that partition i. Let's define LRU[k] DLRUFP,k-TCLRU,i-1] TCLRU,i-1<k<(LRUDRU,FP;+TCLRU,i-1) NLRUFPk-(LRUDRU,FP;+TCLRU,i-1)] (LRUDRU,FP) +TCLRU,-1)<k<(LRUDRU,FP;+ LRUMB-CRU,FP; +TCLRU,i-1) SLRUFPk-(LRUDRU,FP+ LRUMB-CRU,FP;+TCLRU,i-1)] (LRUDRU,FP) + LRUMB-CRU,FP; -TCLRU,i-1) <k<TCLRU,i (10-5) where and TCLRU,-1 =0. In the above equation, the CRUs are directly mapped into contiguous LRUs including sub-band LRUs (SLRU) and mini-band LRUs (NLRU). The mapping between CRUFPi and SLRUFPi or NLRU is defined as follows: LRUFFi|j] = CRUFFIJJ (10-6) 0<j<LMB-CRU,FPi[j];0<i<3 Multiple non-contiguous sub-bands are indexed using the DL/UL Sub-band Assignment A-MAP IE. For a given system bandwidth with Nmax LRUs, the size of allocations comprising contiguous LRUs can be chosen from 1 to Nmax. For each allocation size, resources can be allocated starting from different LRUs in the subframe. Any allocation size 1 <s < Nmax can be assigned in any location starting at LRU index l where ++1 2 24 for 5 MHz and s+1<48 for a 10 MHz system bandwidth. For a 20 MHz system bandwidth, the number of assignable resource sizes is reduced; however, there is no constraint on where those allocations may be made in the subframe as long as S +1 ( 96. The assignable resource sizes are specified such that all resource sizes in increments of one LRU are assignable in the range of 1 to 12 LRUs, only even resource sizes are assignable in increments of two LRUs in the range of 12 to 24 LRUs, resource sizes are assignable in increments of four LRUs in the range of 24 to 48 LRUs, resource sizes are assignable in inc
