1. A client application stored on a non-transitory computer-readable storage medium and associated with a wireless communication device operable in a wireless communication network, the client application executable on the wireless communication device to transmit user data to a host application associated with a host computer providing an over-the-top (OTT) service via the wireless communication network, the client application being operable to:
initiate transmission of the user data to the host application, the wireless communication device being configured to perform operations 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 has a first TA offset value for a first frequency band that is below a frequency threshold for a time division duplex mode and a second TA offset value for a second frequency band that is greater than or equal to the frequency threshold; and
applying the determined TA offset in the uplink transmission, the uplink transmission including the user data.
