Anritsu MT8820C - 5.3. IP Data Transfer Test for 3;4 DL CA

217
IP Data Transfer Test for 3/4DL CA 5.3.
This feature is supported only by the MT8821C.
For 3DL CA, the IP data transfer with carrier aggregation can be tested by installing the MX882012C–036 LTE FDD
DL CA 3CCs IP Data Transfer option (hereafter MX882112C–036 option) in the MT8821C. Furthermore, the installed
MX882012C–011 2x2 MIMO DL option (hereafter MX882112C–011 option) supports IP Data Transfer Test at data
rates up to 450 Mbps for 3DL CA and 2x2 MIMO.
For 4DL CA, the IP data transfer with carrier aggregation can be tested by installing the MX882012C–046 LTE FDD
DL CA 4CCs IP Data Transfer option (hereafter MX882112C–046 option) in the MT8821C. Furthermore, the installed
MX882012C–011 2x2 MIMO DL option (hereafter MX882112C–011 option) supports IP Data Transfer Test at data
rates up to 600 Mbps for 4DL CA and 2x2 MIMO.
NOTE 1: The MX882012C – 006/021/026/031 option must be installed to use the MX882012C – 036 option.
NOTE 2: The MX882012C – 006/021/026/031/41 option must be installed to use the MX882012C – 046 option.
NOTE 3: Testing the DL CA IP Data Transfer requires two application servers and two EPS bearers must be
established. The UE should support Multiple PDN Connection.
The DL CA IP Data Transfer Test requires two application servers because this solution uses two LTE HWs in the
MT8821C.
Furthermore, two EPS Bearers must be established to perform IP data communication with two IP data streams. The
MT8821C will establish the default EPS Bearer as the first EPS Bearer during the Registration procedure, and
establishes the second EPS Bearer by performing the Dedicated EPS Bearer Activation after confirming the Connected
state.
The following figure shows the Layer–2 structure and an image of the IP data streams.

The MT8821C functioning as PCC communicates with the UE using the IP data path of the Default EPS Bearer. The
MT8821C functioning as SCC communicates with the UE using the IP data path of the Dedicated EPS Bearer. The
