A SUDAS has at least one URU, wherein the at least one URU is configured for relaying a signal between at least one base station and at least one user equipment by communicating with the at least one user equipment in a first frequency range and with at least one base station in a second frequency range. The SUDAS has a controller configured for determining a first solution for a resource allocation in the first frequency range. The base station is configured for determining a second solution for a resource allocation in the first frequency range using the first solution.

SUDAS, URU and base station

A transceiver of a user equipment includes a receiving stage, a frontend channel estimator, a frontend channel equalizer, a backend channel estimator, and a backend channel equalizer. The receiving stage is configured to receive an inbound signal from a SUDAC, which enables a relay communication including a frontend communication using extremely-high frequencies and a backend communication using ultra-high frequencies. The inbound signal includes a data portion, a backend control portion and a frontend control portion, the frontend control portion including a frontend evaluation signal and a configuration signal. The frontend and the backend channel estimators are configured to perform channel estimations based on the frontend evaluation signal and the backend control portion, respectively, wherein the frontend and backend channel equalizers are configured to equalize distortions, caused by using the extremely-high and ultra-high frequencies, respectively, based on the channel estimation of the frontend and backend channel estimators, respectively.

Transceiver, a SUDAC, a method for signal processing in a transceiver, and methods for signal processing in a SUDAC

A SUDAC includes a first and a second wireless communication interface and a processor. The first wireless communication interface is configured for using ultra-high frequency in order to establish at least one backend communication link with a base station. The second wireless communication interface is configured for using extremely-high frequency in order to establish at least one frontend communication link with a user equipment. The processor is configured for at least partially forwarding a user information signal received via the frontend communication link to be transmitted via the backend communication link while frequency converting the extremely-high frequency to the ultra-high frequency vice versa. The processor is further configured for extracting control information from the user information signal and for controlling forward parameters of the first or the second wireless communication interface based on the control information.
