基站在一帧最多可以为一个移动台分配一个UIUC等于1-10的UL-MAP信元。除了HARQ数据区，基站在一帧也不能为一个移动台分配多于一个的Mini-subchannel。基站最多可以分配三个UIUC等于12的UL-MAP信元。这三个信元可以用于initial ranging/handover ranging, bandwidth request/periodic ranging, initial ranging for paged MS and/or coorinated association三种无线接入。

UIUC等于0、12、13的分配不能违反上行的瓦片结构，也不能跨区。每个子信道在分配完毕UIUC等于0、12、13的区之后的OFDMA符号应该是3的倍数。所有子信道的时隙边界不允许跨越，必须对齐。除了AAS前导之外，每个区域的符号数都应该是时隙的整数倍。

Subcarrier enumeration shall not be applied to the slots in the UL-MAP indicated by either UIUC = 0 or UIUC = 12.

对于PUSC，上行支持70个子信道；对于optional PUSC，上行支持96个子信道。上行的每一个发射脉冲使用48个数据载波（还是一个Slot）为最小的处理单元。上行一个时隙由3个符号*1个子信道组成，包括48个数据载波和24个固定位置的导频载波。每一个子信道由6个瓦片组成。每个瓦片有3个符号和4个连续载波组成。

Physical Tile应该是从第一个可用载波开始从0计数，一直计数到419。

Tiles(s, n) = Nsubc*n+(Pt[(s+n)mod Nsubc]+ UL_PermBase)mod Nsubc

Tiles(s,n)  is the physical tile index in the FFT with tiles being ordered consecutively from the mostnegative to the most positive used subcarrier (0 is the starting tile index)
n           is the tile index 0…5 in a subchannel
Pt          is the tile permutation
s           is the subchannel number in the range 0…Nsubchannels-1
UL_PermBase is an integer value in the range 0…69, which is assigned by a management entity
Nsubc is the number of subchannels for the FFT size

The data subcarriers per slot are enumerated by the following process:

1) After allocating the pilot carriers within each tile, indexing of the data subcarriers within each slot is performed starting from the first symbol at the lowest indexed subcarrier of the lowest indexed tile and continuing in an ascending manner through the subcarriers in the same symbol, then going to the
next symbol at the lowest indexed data subcarrier, and so on. Data subcarriers shall be indexed from 0 to 47.

2) The mapping of data onto the subcarriers will follow:
Subcarrier(n, s) =(n + 13*s) mod Nsubcarriers

Subcarrier(n,s) is the permutated subcarrier index corresponding to data subcarrier n is subchannel s,
n is a running index 0…47, indicating the data constellation point,
s is the subchannel number, Nsubcarriers is the number of subcarriers per slot.
