Abstract: Methods and apparatuses in a wireless communication system. A method of a UE comprises: receiving, from a base station (BS) in a non-terrestrial network (NTN), a system information block (SIB); determining that the SIB includes first neighboring cell information and first timing information associated therewith; determining that a first neighboring cell is not a candidate cell for a cell selection or re-selection operation when a current time is before or equal to a time indicated by the first timing information; and determining that the first neighboring cell is a candidate cell for the cell selection or re-selection operation when the current time is after the time indicated by the first timing information.

Abstract: Methods and apparatuses for reporting UE location information in a wireless communication system. A method of operating a UE comprises: receiving, from a base station (BS) in a non-terrestrial network (NTN), a message requesting to report the UE location information; generating, based on a positioning operation, first UE location information; generating second UE location information that is derived from the first UE location information; and transmitting, to the BS, the second UE location information as the UE location information.

Abstract: Methods and apparatuses of UE for an efficient neighbor cell search in a wireless communication network. A method of a UE comprises: receiving system information including time instance information for performing measurements on neighboring cells; identifying a time instance included in the time instance information; determining, based on a comparison between a current absolute time and the time instance, whether to perform the measurements on the neighboring cells; and skipping performing the measurements on the neighboring cells based on a determination that the current absolute time is before the time instance.

Abstract: Methods and apparatuses of UE for measurement of TAI updates in an NTN. A method of a UE comprises: receiving, from a BS, an SIB including multiple TAIs and an indication of whether to include a UE location in an NAS registration/tracking area update operation; determining whether to include the UE location based on the indication; identifying information for the UE location; generating a radio resource control (RRC) message including the information for the UE location, wherein the RRC message encapsulates a NAS message; and transmitting, to the BS, the RRC message including the information for the UE location.

Abstract: Methods and apparatuses of UE for performing random access procedures in NTN. A method of a UE comprises: identifying configuration information including a first and second set of resources for a RACH operation; determining whether current location information of the UE is valid for the RACH operation; selecting the first set of resources based on a determination that the current location information of the UE is valid; selecting the second set of resources based on a determination that the current location information of the UE is invalid; transmitting a RACH preamble on the selected first or second set of resources; and receiving, in response to transmitting the RACH preamble, a RAR MAC PDU. The RAR MAC PDU includes a MAC subPDU comprising a first format of MAC subPDU associated with the first set of resources and a second format of MAC subPDU associated with the second set of resources.
