2. Allocation Settings

Number of Symbols

The value must be integral times of 2 for DL PUSC because DL PUSC is divided into slots of 2 symbols x 1 subchannel (section 8.3.3.1 in P802.16Rev2/D6) and be integral times of 2 or 3 for DL AMC because we support 3 Bins by 2 Symbols, 2 Bins by 3 Symbols, 1/2 Bin(s) by 6 Symbols AMC types (section 8.3.6.3 in P802.16Rev2/D6). See example.. See Closedexample.

Refer to section 8.4.2.3 of the 802.16-2004 standard for parameter definitions.

For a 10 MHz BW:

With a frame length of 5 ms and a 50% downlink ratio selected, there is 2.5 ms available or 24 symbols maximum. (Since one symbol is automatically allocated for the preamble, there will be 22 symbols (must be an even number for DL PUSC) available for the downlink subframe portion.

Symbol Offset

Displays the symbol offset from the beginning of the downlink subframe.

The symbol offset displayed includes the default preamble (1 symbol).
