摘要： Systems and methods are described for robust scheduling of beam switching patterns in satellite communications systems. Embodiments operate in context of a hub-spoke satellite communications architecture having a number of gateway terminals servicing large numbers of user terminals over a number of spot beams. The satellite includes switching subsystems that distribute capacity to the user beams from multiple of the gateway terminals in a shared manner according to a beam group switching pattern. The beam group switching pattern is robustly formulated to continue distributing capacity during gateway outages (e.g., when one or two gateway terminals are temporarily non-operational due to rain fade, equipment failure, etc.). For example, the beam group switching pattern can be formulated to minimize worst-case degradation of capacity across user beams, to prioritize certain beams or beam groups, etc.

摘要： Embodiments provide methods, apparatuses, and systems for efficient control signaling over shared communication channels with wide dynamic range. Some embodiments includes a gateway configured to encode and to transmit multiple physical layer headers, including a first physical layer header and a second physical layer header. The first physical layer header may span a first length and represent a first modcode; the second physical layer header may span a second length and represent a second modcode. The second length may be longer than the first length. Embodiments may include multiple terminals in wireless communication with the gateway via satellite, including a first terminal configured to decode the first physical layer header and to determine the first modcode. Embodiments may include a second terminal configured to decode the second physical layer header and determine the second modcode.
