摘要： The present disclosure relates to one or more techniques for communicating across multiple nodes using a single communication link. In certain embodiments, the nodes may be an indoor unit and an outdoor unit of a satellite user terminal for a satellite system. The multiple nodes may communicate with each other using a managed time division duplexed baseband signaling protocol over a single communication link.

摘要： End-to-end beamforming systems (500) include end-to-end relays (503, 1202, 3403) and ground networks (502) to provide communications to user terminals (517) located in user beam coverage areas (519). The ground segment can include geographically distributed access nodes (515) and a central processing system (505). Return uplink signals (525), transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths (1702) in the end to end relay and are relayed to the ground network. The ground network, using beamformers (513, 531), recovers user data streams transmitted by the user terminals from return downlink signals (527). The ground network, using beamformers (513, 529) generates forward uplink signals (521) from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals (522) that combine to form user beams.

摘要： Techniques for end-to-end beamforming in a wireless communication system using access node clusters that are distinct from a user coverage area are described. Forward link end-to-end beamforming may involve multiple access nodes in one or more access node clusters transmitting signals that, when relayed by multiple transmit/receive signals paths within an end-to-end-relay, form user beams in the user coverage area. Return link end-to-end beamforming includes applying beamforming weights to signals transmitted by user terminals and relayed by multiple transmit/receive signals paths in the end-to-end relay to the access nodes to form return beam signals associated with return user beams. The access node clusters may overlap or be outside the user coverage area, and multiple access node clusters may serve one or more user coverage areas selectively or concurrently. Multiple feeder-link frequency bands may be employed by the same or different access node clusters.
