State

Choice: On, Off

Double-click or use the drop-down menu to set the state of the PUSC Subchannels Bitmap.

Bitmap Byte #0 to Byte #8

Range: 0x00 to 0xff

Set the uplink bitmap byte.

OPUSC Subchannels Bitmap

Range: 0x00000000000000000000000000 to 0x00ffffffffffffffffffffffff [Hex]

Set the uplink subchannels bitmap of OPUSC Zone.

State

Choice: On, Off

Uplink Zones

Use the Add Button to add a new uplink zone type to the frame configuration from the pull-down menu. When a zone is added, the software inserts the zone (up to eight) in the tree view and adds it to the frame plot view.

Use the Delete Button to delete the selected zone. The zone to be deleted is indicated by the in the first column. The first PUSC zone cannot be deleted.

Use the Copy Button to add a new zone that has the same configuration as the currently selected one (indicated by the in the first column).

Use the Up and Down arrows to reposition the currently selected zone (indicated by the in the first column).

Zone#

Displays the zone index number.

Type

Choices: PUSC, OPUSC, AMC, Sounding

• PUSC = partial usage of subchannels

• OPUSC = optional partial usage of subchannels

• AMC = adaptive modulation and coding (AMC 2x3 zones are supported.)

• Sounding = Create uplink signal with sounding zone and sounding messages with various values for Max Cyclic Shift Index (P) and Decimation Value (D) with equal power assignment to all pilots.

Displays the zone type selected from the drop-down menu.

Perm Base

Range: 0 to 69

Specifies the uplink permutation base.

# of Symbols

Specify the number of symbols in this zone. See also Number of Symbols.

Sym Offs

Displays how much the zone is offset from the beginning of the downlink subframe. The symbol offset displayed includes the default preamble (1 symbol). 

Max# of Subchs

Displays the maximum number of subchannels per symbol for the zone configuration. See also Max. Number of Subchannels.
