in the non-FFR case, there are two assignment A-MAP groups with the minimum resource units of one and two MLRUs in each group; (2) when QPSK (1/2, 1/8) is used in the non-FFR case, there are two assignment A-MAP groups with the minimum resource units of one and four MLRUs in each group; (3) when QPSK 1/2 is used in the FFR reuse-3 region assignment A-MAP and QPSK (1/2, 1/4) is used for the reuse-1 region assignment A-MAP, there are three assignment A-MAP groups with the minimum resource units of one, one, and two MLRUs in each group; and (4) when QPSK 1/2 is used for the FFR reuse-3 assignment A-MAP and QPSK (1/2, 1/8) is used for the reuse-1 assignment A-MAP, there are three assignment A-MAP groups with the minimum resource units of one, one, and four MLRUs in each group. There is an 8-bit index that is used for assignment A-MAP group size indication. The assignment A-MAP group with more robust MCS is located before the assignment A-MAP group with less robust MCS. The exact size of the group with more robust MCS is signaled when possible, to minimize resource consumption. The following describes the methodology for allocation of MLRUs for non-FFR region assignment A-MAPs using QPSK (1/2, 1/4). The total number of MLRUs for assignment A-MAP Ntotal is given by Ntotal = [2G1(I) + G2(1)] where 0 Ntotal < 48, 0 G1(1) < 24 is the number of assignment A-MAPs in Group 1 using QPSK 1/4 and 0 G2(1) < 48 is the number of assignment A-MAPs in Group 2 using QPSK 1/2. For non-FFR configuration with Group 1 using QPSK 1/4 and Group 2 using QPSK 1/2, the lookup tables shown in Table 10-1 can be generated iteratively using the following equations for all values of Ntotal and k [2]: k = = 0,1,...,LN101a1/2] Ntotal -24+3k, k=0,1,2,3, = < N total < 29 Ntotal 29 4k, k = 0, 1, 2, 3, 30 Ntotal < 32 30 + 4k, k = 0, 1, 2, 3, 33 Ntotal < 34 (10-1) Ntotal -32+3k, k = 0, 1, 2, 3, 35 Ntotal < 39 Ntotal 32 4k, k = 0,1,2, 40 Ntotal < 42 Ntotal 32 3k, k = 0,1,2, 43 Ntotal < 48 G2(I) = Ntotal 2G1( (I) Table 10-1 The Number of Assignment A-MAPs
