Zone#2-8, PUSC (Advanced 802.16 OFDMA)

PUSC, Zones 2 through 8 have two additional parameters. These parameters are not present in Zone#1, PUSC. Other parameters are the same for all PUSC zones.

1. Zone Settings

Permutation Base

Use this cell to select the permutation base (0 to 31) to be used for subchannel randomization for all segments in the PUSC downlink zone as specified in section 8.4.5.3.4. Space-Time Coding (STC)/DL Zone switch IE format of P802.16-2004/Cor1/D3. Accepted values are 0 to 31.

This parameter does not apply to Zone#1, PUSC.

PRBS ID

Use this cell to set the PRBS ID (0 to 2) in the zone to be used for subchannel randomization as specified in 8.4.5.3.4 Space-Time Coding (STC)/DL Zone switch IE format of P802.16-2004/Cor1/D3.

This parameter does not apply to Zone#1, PUSC.

Use All Subchannels

Double-click or use the drop-down menu to turn Use All Subchannels On or Off.

This parameter is read-only for the first PUSC zone, and is always Off.

Zone Boost

Double-click or use the drop-down menu to turn Zone Boost On or Off.

Zone Boost is not available when Use All Subchannels is On.

Zone Boost Factor [dB]

Displays the zone boost amplitude in dB when zone boosting is enabled.

This value is automatically calculated based on Group Bitmask for PUSC zone and AMC Physical Bands Bitmap for AMC zone. Refer to 8.3.9.6 in P802.16Rev2/D6 for details.

STC Type

Double-click or use the drop-down menu to select the STC type, which decides whether this DL-PUSC zone implements Matrix A, Matrix B or None STC encoding. For the first DL-PUSC zone, it should always be None.

MIMO DL IE Format

Double-click or use the drop-down menu to select the MIMO DL IE Format.

MIMO DL IE Format is only available in STC mode.

Dedicated Pilots

Choices: On, Off

Use the drop-down menu or double-click to turn Dedicated Pilots on or off.

2. Allocation Settings

Number of Symbols

Specify the number of symbols in this zone.

The value must be an even number because DL PUSC is divided into slots of 2 symbols x 1 subchannel (section 8.4.3.1 in 802.16-2004/Cor/D3). 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).  

Max. Number of Subchannels

Displays the maximum number of subchannels per symbol for the zone configuration.

Auto Allocation

Double-click or use the pull-down menu to turn this feature on or off.
