F-Traffic Config

Last updated: July 22, 2008

This section is only applicable to the lab application and to a test application with the required feature license.

F-Traffic Config determines the forward transmission format (packets, slots, preamble) that the test set will be used to transmit the forward data packets (non-signaling message) when the following conditions are met:

• the test set is in Active Cell operating mode with the DRC Value Fixed Mode Attribute set to off and the Physical Layer Subtype is set to subtype 2 or subtype 3 physical layer (see Release A Physical Layer Subtype or Release B Physical Layer Subtype ).

When the DRC Value Fixed Mode Attribute is off, the AT requests the DRC value based on the current link conditions as in real system operation. For subtype 2 and subtype 3 physical layer subtype, there are multiple transmission formats per each requested DRC value (see the table below). F-Traffic Config setting determines which transmission format is used for each requested DRC value:

• Canonical - canonical transmission format for the DRC value received
• Short Packet 1 - largest short packet size (non-canonical) format for the DRC value received
• Short Packet 2 - 2nd largest short packet size (non-canonical) format for the DRC value received
• Short Packet 3 - 3rd largest short packet size (non-canonical) format for the DRC value received

If there are no short packet formats or less than three short packet formats for the DRC value, the settings collapse as shown in the table below. The highlighted row for each DRC Value is called the canonical transmission format. The canonical transmission format is defined as the transmission format with the largest packet size for the DRC Value. Additional transmission formats for the DRC Value are called short packet (or non-canonical ) transmission formats.

When the DRC Value Fixed Mode Attribute is set to on, the forward transmission format for subtype 2 and subtype 3 physical layer is determined by F-Traffic Format .
