Abstract: Apparatus and method for communication in non-terrestrial networks are provided. Downlink transmissions are received (400) from one or more non-terrestrial nodes. Signal strengths and/or signal quality of the transmissions are measured (402) from the one or more non-terrestrial nodes. Transitions between line-of-sight and non-line-of-sight states regarding the one or more non-terrestrial nodes are determined (404). Locations of the one or more non-terrestrial nodes and the apparatus are determined (406) and elevation and azimuth angles to the one or more non-terrestrial nodes from the apparatus are calculated (408). A database of the line-of-sight and non-line-of-sight states is generated (410) as a function of elevation and azimuth angles and apparatus location and utilised (412) to determine expected line-of-sight and non-line-of-sight states for non-terrestrial nodes.

Abstract: Apparatuses and methods for communication in non-terrestrial networks are provided. Downlink transmission from a satellite node is received (300). Pathloss of uplink transmission to the satellite node is estimated (302). Based on the path loss, it is determined (304) whether uplink transmission of the apparatus can reach the satellite node and uplink transmission suspended (306) if determination indicates that the transmission will not reach the node.

Abstract: In accordance with example embodiments of the invention there is at least a method an apparatus to perform based on determining an routing point switch in a communication network by a serving base station from a source routing point to a target routing point: creating a pre-compensation transition window for start and end of transition time between an availability of the source routing point and an availability of the target routing point, wherein the creating is starting at a point in time and using a duration of the pre-compensation transition window on at least an uplink transmission with the target routing point and at least a downlink reception from the source routing point; and based on the pre-compensation transition window, performing at least one of time or frequency pre-compensation to accommodate for time differences at the serving base station at least one of during or after the routing point switch and for differences in a propagation path between the source routing point and the target routing point to at least maintain continuity of communication by the apparatus during the start and end of transition time.

Abstract: A method is provided that includes scheduling transmission of system information blocks (SIBs) including information elements with assistance information for a first aerospace platform, and a separate at least one information element with assistance information for a second aerospace platform. The first aerospace platform and the second aerospace platform are configured to provide respectively a first non-terrestrial network (NTN) cell and a second NTN cell that are quasi-Earth-fixed cells serving a geographic area for limited periods of time. The method also includes causing a user equipment in the first NTN cell to acquire the separate at least one information element with the assistance information for the second aerospace platform, during a period of time the geographic area is served by the first NTN cell, before the geographic area is served by the second NTN cell.

Abstract: Common delay(s) are set for a base station, the base station and a UE able to communicate via signals and to use the common delay(s) in communication. The common delay(s) correspond to delay in communication of the signals in a path from a simulated satellite to a reference point, which is a point selected between the base station and the simulated satellite. The UE is placed in a known location. Ephemeris values are set for the base station for the simulated satellite and caused to be broadcasted toward the UE. The ephemeris values represent positioning of the simulated satellite through which the signals are supposed to travel. In response to communication over the path by the UE, error is determined corresponding to at least timing at least between the UE and the reference point.

Abstract: Systems, methods, apparatuses, and computer program products for management of updates in scheduling offset via system information and soft indication of system information modification are provided. For example, a method can include identifying, by a user equipment, a time of application of a new non-terrestrial-network system information. The method may also include waiting to apply the new non-terrestrial-network system information until the time of application. The method may further include applying the new non-terrestrial-network system information at the time of application, conditioned on the new non-terrestrial-network system information being received before the time of application.
