A user device UE for a wireless communication with a plurality of wireless network elements includes a plurality of antennas. The plurality of antennas are configured to form a plurality of spatial or directional beams. The user device is configured to provide simultaneously a plurality of independent wireless communication links using the plurality of spatial or directional beams, wherein the user device is configured to provide a first wireless communication link with a first wireless network element using a first spatial or directional beam and to provide a second wireless communication link with a second wireless network element using a second antenna beam.

Multi-connectivity user device for wireless communication networks

A receiver is described which receives data from a transmitter. The data is included in a data block which includes at least one code block, and the code block has a plurality of parts. A first part of the code block is used for estimating a decodability of the code block at the receiver. The first part of the code block is arranged in the data block ahead of the remaining one or more parts of the code block. The receiver estimates, prior to receiving the entire data block, the decodability of the code block using the first part of the code block.

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.

A digital receiver includes a pre-de-interleaver processing block for receiving a receive signal including reception data units quantized using a quantization rule. The digital receiver additionally includes a controllable compressor for compressing the data units into a compressed representation, a controllable time-de-interleaver being configured for applying a varying interleaving size in data units, and a controller for controlling the controllable processor or the controllable time-de-interleaver. The controller is configured for controlling the compressor or the time-de-interleaver so that a higher interleaving size such as a higher interleaving time or a higher number of data units per second is applied, when a compression in a lower number of bits is active.
