Abstract: Methods and apparatuses in a wireless communication system for a user equipment (UE) to perform a power management method. The method includes receiving, by the UE, one or more power parameters for a non-terrestrial network (NTN). The method also includes selecting a power management method from one of: a predictive transmit power method based on time and the distance between the UE and an NTN entity or a non-predictive transmit power method. The method also includes determining a power based on the power management method and the power management parameters. The method further includes transmitting a signal to the reception point using the power.

Abstract: A method for operating a user equipment (UE) comprises receiving system information including: information corresponding to location coordinates for a non-terrestrial network (NTN) gateway; information corresponding to a processing delay between the UE and a base station (BS); and information corresponding to a reference point location; determining a timing advance based on a timing difference between the reference point location and the BS; and transmitting a timing advance report based on the determined timing advance.

Abstract: Methods and apparatuses in a wireless communication system. A method of operating a user equipment (UE) includes generating an indicator indicating that the UE is capable of supporting adjusted quality of service (QoS), wherein the adjusted QoS corresponds to scaling of QoS parameters associated with an existing QoS indicator. The method also includes generating a capability message comprising the indicator. The method also includes transmitting, to a base station (BS), the capability message including the indicator. The method further includes receiving, from the BS, a message comprising an adjusted QoS value based on the scaling of QoS parameters associated with the existing QoS indicator.

Abstract: Methods and apparatuses for signaling and trigger mechanisms for handover in a wireless communication system. A method for operating a user equipment (UE) includes receiving system information and information corresponding to different classes for handover signaling; transmitting a capability information including information indicating support of enhanced signaling mechanisms; receiving configuration information including measurement information and handover information based on the capability information; determining completion of handover based on the configuration information; and transmitting a completion of handover indication using a non-Radio Resource Control mechanism based on the completion of handover determination.
