You can connect it to ground, or you can decide not to connect it. From the datasheet: 'Soldering Pad 39 to the Ground of the base board is not necessary for a satisfactory thermal performance. If users do want to solder it, they need to ensure that the correct quantity of soldering paste is applied.' ('the correct quantity' probably means 'not too much' here; you don't want solder paste squeezed everywhere.)
