DL TX Pattern
This enables configuration of the downlink to transmit UE specific data on all subframes (normal
operation) or to transmit UE specific data only on downlink subframes one and six. This function is
primarily used for Radio Conformance Testing.

RV Coding Sequence
A redundancy version (or RV) is used during the rate matching process when a transport block is being
encoded. If a transport block is retransmitted, a different redundancy version from the original
transmission is generally used – this enables incremental redundancy to improve the chances of the
transport block being decoded.
For the UL, the sequence of RV values used is fixed (to 0,2,3,1) as specified in 3GPP 36.321. On the DL,
however, the sequence can be modified. The main reason to use this setting is to perform some of the
RCT tests specified in 3GPP 36.521-1, where a different sequence is specified.

Special SF control
Determines if any special subframes in the uplink/downlink configuration are used to transmit downlink
data or not. A setting of Default means that they will be used, a setting of Null means that they will not.
Some RCT tests demand that they are not used.
