1. A method in a wireless communication device, comprising:determining a timing advance, TA, offset for uplink-downlink switching, wherein:
the TA offset depends on a duplex mode of a cell in which an uplink transmission occurs from the wireless communication device to a network node and depends on a frequency range of the uplink transmission, and
the TA offset is a predetermined constant value for a predetermined frequency band and duplex mode; and
applying the determined TA offset in the uplink transmission.
