An apparatus configured for wirelessly communicating in a wireless communication network includes a wireless interface arrangement having a signal maintenance capability to separate at least one data stream. The apparatus is configured for wirelessly transmitting, to a receiving apparatus, a capability signal having a capability information indicating the signal maintenance capability.

Considering data stream separation capability in wireless communication networks

An apparatus configured for wirelessly communicating in a wireless communications network includes a wireless interface configured for wireless communication and a controller configured for controlling a beam pattern of the wireless interface and at least one communication parameter of the wireless interface. The apparatus is configured for receiving a locking signal indicating a request for locking at least a part of the beam pattern and the at least one communication parameter. The controller is configured for locking at least the part of the beam and the at least one communication parameter responsive to the locking signal.

Apparatus, measurement system and measurement setup and methods for testing an apparatus

A method includes defining a Center-of-Radiation Reference for a device under test, the CORR indicating a reference origin of an electromagnetic wave pattern formable with the DUT; determining a 3-dimensional orientation information with respect to the CORR, the 3-dimensional orientation information indicating a direction of the electromagnetic wave pattern; and providing the CORR and the 3-dimensional orientation information to a measurement system.

Methods and measurement systems for precisely evaluating a device under test

There are disclosed techniques for puncturing and/or overlaying transmission in case of necessity of on-demand (e.g., urgent) commutations. In particular, transceivers, user equipments, systems, methods and non-transitory storage units are disclosed. For example, there is disclosed a transceiver of a wireless communication network, wherein the transceiver is configured to operate in a puncturing mode by puncturing a downlink, DL, transmission of payload information in a channel originally allocated to the DL transmission of payload information, to obtain, within the originally allocated channel for the DL transmission of payload information, a DL free area for an uplink, UL, transmission of a user equipment, UE, of the wireless communication network.

Punctured information for flexible/full duplex communication

A method for evaluating an apparatus having at least one antenna array, the apparatus configured for forming a plurality of communication beam patterns using the antenna array, includes positioning of the apparatus in a measurement environment or moving/switching the probe/link antenna(s) of the measurement environment around the apparatus adapted to measure beam patterns and controlling the apparatus so as to form a predefined beam pattern of the plurality of communication beam patterns. The method includes measuring the predefined beam pattern using the measurement environment and/or the apparatus.

Method and measurement environment, apparatus to be tested

Among network devices for use within a wireless communication network, a transmitting network device is configured to transmit to a receiving network device via a control channel one or more control signals for configuring the receiving network device for a characterization of at least one of the transmitting network device and the receiving network device and/or for a characterization of one or more communication channels between the transmitting network device and the receiving network device.

Network device for use in a wireless communication network and an end-to-end over-the-air test and measurement system for one or more network devices

Disclosed is a radio frequency communication and jamming device configured for physically secured friendly radio frequency communication and for jamming hostile radio frequency communication, the radio frequency communication and jamming device including: an antenna arrangement having a transmission section for transmitting outgoing signals and a receiving section for receiving incoming signals; a receiver device configured for extracting an incoming information signal from the incoming signals received via the receiving section of the antenna arrangement in a receiving frequency band; a jamming generator configured for generating at least one jamming signal for jamming at least one jamming frequency band, wherein the jamming signal is transmitted as one of the outgoing signals via the transmission section, wherein the at least one jamming frequency band includes the receiving frequency band; and a self-interference cancellation device configured for cancelling portions of the at least one jamming signal in the incoming signals received via the receiving section at least in the receiving frequency band.
