1. A method in a terminal device having Dual Connectivity, DC, with a master network device and a secondary network device, the method comprising:
determining, for a split bearer, to split data to be transmitted to the master network device and the secondary network device based at least on Listen Before Talk, LBT, statistics associated with a connection to the secondary network device, the determining comprising:
determining a data amount threshold based on the LBT statistics; and
determining to split the data when an amount of the data, as stored in a buffer, is larger than or equal to the determined data amount threshold; and
splitting the data for transmitting to the master network device and the secondary network device over the split bearer.
