Configuring Downlink Enhanced L2

This section describes how to activate, verify, and deactivate the optional feature WRFD-010685 Downlink Enhanced L2.

Prerequisites

Dependencies on Hardware

This feature does not have any special requirements for hardware.

Dependencies on Other Features

The feature WRFD-010610 HSDPA Introduction Package must be configured before this feature is activated.

License

The license controlling this feature has been activated. For details on how to activate the license, see Activating the UMTS LicenseGuide.

Others

The UE is of 3GPP R7 or later and supports this feature.

Context

The Downlink Enhanced L2 feature eliminates contradictions between high-rate transmission that requires a large PDU size and cell-edge coverage that requires a small PDU size by using flexible Protocol Data Unit (PDU)sizes. This feature enables dynamic adjustment of the PDU size. This improves transmission efficiency on the Iub and Uu interfaces and increases the cell-edge throughput and coverage radius.

This feature is a prerequisite for the features DL 64QAM, 2x2 MIMO, and Enhanced CELL_FACH.

Procedure

Activation Procedure

1. Run the BSC6900 MML command SET UFRC to set the RNC-level downlink layer 2 enhancement parameters. In this step, set max PDU size.

2. Run the BSC6900 MML command MOD UCELLALGOSWITCH. In this step, set Cell Hspa Plus function switch to DL_

Verification Procedure

1. Start Uu interface tracing on the BSC6900 LMT, as shown in Figure 1.
