1. A method in a terminal device, wherein the terminal device is configured with different numerologies for at least two carriers and at least two active bandwidth parts, BWPs, each active BWP is associated with a numerology and the numerology comprises subcarrier spacing, SCS, the at least two carriers belong to a Timing Advance Group, TAG, the method comprising:
receiving a time advance, TA, command from a network device;
determining a TA granularity; and
determining a TA value based at least partly on the TA command and the TA granularity,
wherein the TA granularity of the TAG is determined based on a numerology with the largest SCS of the multiple numerologies associated with the at least two active BWPs.
