In one embodiment of the present disclosure, a satellite communication system includes a satellite constellation including a plurality of satellites in non-geosynchronous orbit (non-GEO), wherein at least some of the plurality of satellites travel in a first orbital path at a first inclination, and an end point terminal having an earth-based geographic location, the end point terminal having an antenna system defining a field of regard for communicating with the satellite constellation, wherein the field of regard is a limited field of regard, wherein the field of regard is tilted from a non-tilted position to a tilted position, and wherein the tilt angle of the tilted position is a function of the latitude of the geographic location.

Apparatus, methods, and computer-readable media for facilitating interruption handling in satellite-based communications are disclosed herein. An example method for wireless communication at a UE includes determining an interruption for a satellite-based communication link based in part on UE location information and blockage information of an obstruction that blocks LOS propagation for the satellite-based communication link. The example method also includes refraining performance of one or more communication link correction procedures for a time period associated with the interruption.

In a wireless communication system in which a relay apparatus provided in a mobile object wirelessly communicates with a plurality of communication apparatuses placed at different locations, the relay apparatus includes a receiver that receives a signal transmitted from each of the plurality of communication apparatus, the signal including position information indicating a position of each communication apparatus, a measurement unit that measures a congestion level of communication, a control unit that divides a communication target area into a plurality of small areas in accordance with the positions of the plurality of communication apparatuses and the congestion level of communication and generates area information indicating a position of each of the small areas, and a transmitter that sequentially transmits a plurality of pieces of the area information when the relay apparatus is positioned in a range in which the relay apparatus can communicate with the communication apparatuses, and each communication apparatus includes a storage unit that stores transmission data, a receiver that receives the area information, a control unit that determines whether a position of the communication apparatus is included in the small area in accordance with the area information, and a transmitter that transmits a signal including the transmission data and position information indicating a position of the communication apparatus to the relay apparatus when the position of the communication apparatus is included in the small area.
