The apparatus and method comprises: identifying a non-terrestrial network (NTN) type associated with an NTN; configuring a set of operational parameters for performing wireless communication based on the NTN type; identifying, based on a network configuration associated with the NTN, one or more interfaces to transmit information indicating the NTN type; and transmitting, to a user equipment (UE) or a network function (NF), the information indicating the NTN type via the identified one or more interfaces.

Abstract: Methods and apparatuses for time adjustment during handover in non-terrestrial networks. A method of operating a user equipment (UE) includes receiving configuration information for a first and a second RS and receiving the first RS from a first base station (BS) and the second RS from a second BS. The method also includes measuring a time of arrival of the second RS relative to a time of arrival of the first RS, determining a differential propagation delay between the first RS and the second RS based on the times of arrival. The method further includes determining a transmission time for an uplink (UL) UE-dedicated channel to the second BS based on the differential propagation delay and transmitting the UL UE-dedicated channel to the second BS based on the determined time.

Abstract: A method for managing mobility in a wireless communication system includes determining an initial mobility management configuration for a user equipment (UE) in a serving cell based on cell configuration information. The method also includes identifying a current context of the UE based on reports received from the UE. The method further includes determining an updated mobility management configuration for the UE based on the current context of the UE. Additionally, the method includes transmitting a configuration message to update the UE with the updated mobility management configuration. The method also includes determining whether to trigger a handover of the UE based on comparison of the serving cell and neighbor cell measurements with thresholds. The method further includes triggering the handover based on the updated mobility management configuration.

Abstract: Methods and apparatuses in a wireless communication system. A method of operating a base station (BS) includes generating an indicator indicating that the BS is capable of supporting a high-capacity radio network temporary identifier (HC-RNTI), wherein a size of the HC-RNTI is based on a configurable granularity; generating a system information block including the indicator and information indicating the size of the HC-RNTI; transmitting, to a user equipment (UE), the system information block; and transmitting, to the UE, the HC-RNTI, wherein the HC-RNTI is allocated to the UE.

Abstract: A method and apparatus in a wireless communication system is provided. The method and apparatus comprises: identifying a virtual tracking area (VTA) to tracking area (TA) (VTA-TA) mapping information indicating mappings between (i) TA identifiers (TAIs) associated with a non-terrestrial network (NTN) entity and (ii) VTAs associated with geographical areas as a function of time; identifying one or more TAIs at an instant or during a time period based on the VTA-TA mapping information; transmitting a radio resource control (RRC) request message including the one or more TAIs; and receiving an RRC response message corresponding to the RRC request message based on the one or more TAIs. The RRC response message includes a virtual registration area (VRA).

Abstract: A method and apparatus for implementing a supplemental channel in an IS-2000 CDMA network includes a system that determines when to initiate a supplemental channel transmission, when to terminate a supplemental channel transmission, the period or duration of a supplemental channel, and, finally, the data rate of the supplemental channel. In short, an implementation for a supplemental channel is provided that considers the power capacity of the BTS, the desire to minimize interference, the desire to maximize revenue and the number of users, and the desire to minimize the probability of blocking (a user being denied access).

Abstract: A method for efficient power control in a (CDMA based) fixed wireless system. The method comprises the steps of (1) monitoring a transmission link of the fixed wireless system for an occurrence of a fade, (2) recording a number of power increases to the transmission link due to said fade, and (3) reducing the power to an appropriate level when said fade is over. The adjusting step includes the steps of determining an appropriate power-down step size, which results in saving power, wherein the step size is influenced by a frame error rate (FER) and selected to maintain a desired FER, and dynamically decreasing the power by the appropriate power-down step size, thereby conserving power and increasing system capacity.
