How slot format is signalled to UE

As we know there are different numerology introduced in 5G like in below table, how does UE knows the current slot format ?

sub carrier spacing(mu) and the cyclic prefix for a bandwidth part are obtained from the higher-layer parameter subcarrierSpacing and cyclicPrefix, 
if (UE is provided higher layer parameter tdd-UL-DL-ConfigurationCommon &&  UE is not provided higher layer parameter tdd-UL-DL-ConfigurationCommon2
)
{ A reference subcarrier spacing mu by higher layer parameter referenceSubcarrierSpacing

-     A slot configuration period of  P msec by higher layer parameter dl-UL-TransmissionPeriodicity

-     A number of slots dslots with only downlink symbols by higher layer parameter nrofDownlinkSlots

-     A number of downlink symbols dsym   by higher layer parameter nrofDownlinkSymbols

-     A number of slots uslots with only uplink symbols by higher layer parameter nrofUplinkSlots

-     A number of uplink symbols usym by higher layer parameter nrofUplinkSymbols

}




if (UE is provided tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationCommon2)

{A reference subcarrier spacing mu2 by higher layer parameter referenceSubcarrierSpacing;

-     A slot configuration period of P2 msec by higher layer parameter dl-UL-TransmissionPeriodicity;

-     A number of slots dslots2 with only downlink symbols by higher layer parameter nrofDownlinkSlots;

-     A number of downlink symbols dsym2 by higher layer parameter nrofDownlinkSymbols;

-     A number of slots uslots2 with only uplink symbols by higher layer parameter nrofUplinkSlots;

-     A number of uplink symbols usym2 by higher layer parameter nrofUplinkSymbols.

}

this is just extension of previous example. Now additional S2 slots' format is determined with above information which is similar to previous case,


Additionally higher layer parameter tdd-UL-DL-ConfigDedicated, is specific to flexible symbols.
