摘要： In a satellite communication system to perform routing with a communication channel via a satellite, when an earth station is to enter the satellite communication system, a control station notifies the earth station, using a control channel via the satellite, of the network address of the earth station managed by the control station. After that, the earth station can establish the communication channel via the satellite.

摘要： 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.

摘要： A wireless communications system includes a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, can transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device.
