1. An end-to-end beamforming system comprising:

  • a plurality of geographically distributed access nodes each having an end-to-end beam-weighted forward uplink signal output; and

    an end-to-end relay comprising;

    an array of cooperating feeder-link constituent receive elements, in wireless communication with the distributed access nodes;

    an array of cooperating user-link constituent transmit elements in wireless communication with a plurality of user terminals; and

    a plurality of forward-link bent-pipe transponders, each coupled between a respective one of the cooperating feeder-link constituent receive elements and a respective one of the cooperating user-link constituent transmit elements,such that receipt of superpositions of a plurality of beam-weighted forward uplink signals via the cooperating feeder-link constituent receive elements forms forward downlink signals in the forward-link bent-pipe transponders, and transmission of the forward downlink signals by the cooperating user-link constituent transmit elements contributes to forming a forward user beam servicing at least some of the plurality of user terminals.
