Resource Unit Setup (Advanced)

The column headings in the Resource Unit Setup data grid are identical for all channels but the data displayed under each column will vary depending on the channel configuration. The coding data, N_TFCI, N_TPC, N_SS, and N_DATA, depends on the slot format of the selected channel as specified in TS 25.221 V7.0.0, Table 8F and 8G. Slot formats for 8PSK modulation are listed in Table 8.

In most Resource Unit Setup windows, Timeslot, Channel Code, User ID, and Slot Format are editable parameters with the following exceptions:

Index

Range: depends on channel configuration

Displays the index number associated with resource unit in the timeslot. The number of indexes displayed depends on the allocated resource units for the link direction and data rate.

Timeslot

Range: depends on channel configuration

Enter a value to change the timeslot assignment for the channel, if desired. If a timeslot is not available due to a conflicting channel code assignment, the status bar displays an error message.

Channel Code

Range: 1 to 16

Enter a value to change the channel code assignment, if desired. The channel code cannot exceed the spreading factor value.

User ID

Range: 1 to 16

Enter a value to identify the user on this channel. The User ID is corresponding to the midamble shift.

There are two midamble allocation schemes in this software: the UE specific scheme and the default scheme.

Power

Range: –60 to 0 dB

Displays the normalized power for this timeslot relative to the other timeslots in the channel. See Power Settings for details.

Slot Format

Range: 0 to 24 (downlink); 0 to 69 (uplink); 0 to 24 (8PSK for both uplink and downlink)

Displays the slot format for the channel as specified in the standards. The slot format determines the settings for other parameters that are not configurable or viewable. All coupled parameters follow the 3GPP standards.

Spreading Factor

Displays the spreading factor as specified in the standards for the slot format.

N_TFCI

Displays the number of TFCI bits as specified in the standards for the slot format.

N_TPC

Displays the number of TPC bits as specified in the standards for the slot format.

N_SS

Displays the number of synchronization shift bits as specified in the standards for the slot format.

N_Data

Displays the number of data bits as specified in the standards for the slot format.
