Abstract: Within a satellite communications system, a base station communicates with standard compliant user equipment (UE) via a satellite having a field of view. The base station has a processor that instructs the satellite to generate a wide beam signal covering a plurality of cells in the field of view, and detects an access request from a user equipment within the plurality of cells over the wide beam signal. The base station, comprising a processing device such as an eNodeB, then generates one or more network broadcast/access signals that is uplink to a satellite and broadcasted via one or more nominal beams generated by the satellite, covering all the inactive cells, one of the plurality of cells having the access request.

Abstract: Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

Abstract: An antenna and an antenna system that has the antenna, and relates to the field of wireless communication technologies. The antenna can allow a high frequency to pass through and block a low frequency or allow the low frequency to pass through and block the high frequency, and can be used in combination with other antennas to form an antenna system. In addition, in the antenna system, the antenna can also share a same antenna aperture surface with other antennas. The antenna can reduce costs while meeting a working requirement of a multi-band antenna, and can be used for flexible and changeable usage scenarios.
