1. Introduction
For the determination of resource index in the 5 MHz system, to ensure the correct mapping from the
resource index to the beginning LRU and the allocated LRU size in the 5 MHz system. The dimension of the
vector Ia shall be 24, and the range of the beginning LRU L shall be from 0 to 23.
Besides, for the 20MHz system, the possible assignment LRU size does not include size S=1. Thus, the range
of the beginning LRU L shall be modified.
2. Proposed Text for IEEE P802.16m/D1
15.3.6.5.4.2 DL basic assignment A-MAP IE
============================ Start of Proposed Text ==================================
[Modify the text in line 6, page 328 as follows.]
The ith element of Ia, 1≤ i ≤2324 for 9 bit resource indexing in a DL/UL subframe for a 5 MHz system
bandwidth is defined as:
[Modify the text in line 12, page 328 as follows.]
The resource index RI for an allocation of size S LRUs beginning at LRU L is computed as
RI = Ia(S) + L, 1≤ S ≤24 and 0≤ L ≤2423
[Modify the text in line 48, page 327 as follows.]
The resource index RI for an allocation of size S LRUs beginning at LRU L is computed as
if I a  S   0 or S  1
Ia  S   L

RI  
if I a  S   0 and S  1

notassignalble
where 1 ≤ S ≤ 96 and 10 ≤ L ≤ 95
The ABS first determines if the required resource size is assignable by checking if the (S-1)th Sth element in IaIa
has a non-zero value.
