Abstract: 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.

Abstract: A communications device transmits/receives data from a mobile communications network including one or more network elements forming plural cells. Each cell is allocated a cell identifier. For each cell the network elements provide a wireless access interface providing plural communications resource elements across a frequency range of a first carrier, and divided in time into plural frames. The one or more network elements transmit in one or more of the frames a synchronization sequence, each synchronization sequence providing an indication of a cell identifier. A controller calculates an estimate of a cell identifier from the detected synchronization sequence, and uses the cell identifier to transmit/receive the data to/from the mobile communications network via the wireless access interface. A relative temporal location of the synchronization sequence within the frame provides the communications device with an indication of the cell identifier of the cell.
