  • Patent number: 11985662
    Abstract: A user equipment (UE) includes one or more non-transitory computer-readable media containing computer-executable instructions embodied therein, and at least one processor coupled to the one or more non-transitory computer-readable media. The at least one processor configured to execute the computer-executable instructions to receive downlink control information (DCI) on a downlink (DL) channel of a non-terrestrial network (NTN), the DL channel reception ending in a first slot, and transmit an uplink (UL) transmission on a UL channel of the NTN in a second slot. The second slot is separate from the first slot by a timing offset, where a duration of the timing offset is dependent on a type of the UL transmission and a numerology of the UL transmission.
