Set k2=2, enable slot 0
In the past, activation of slot 0 (i.e., after the switch UL->DL) resulted in many retransmissions. This does not seem to be the case anymore, and we can therefore activate slot 0 also in TDD.
In the past, setting k2=2 for 5ms TDD periods resulted in increased ping RTT and/or reestablishment requests. These problems do not appear anymore, and we can allow k2=2. Solved #518 (closed)
