Abstract: A device and method for operating a wireless communication network (100), wherein a communication channel (112) of the wireless communication network (100) at least temporarily connects a first device (104) to an access point (102) in the wireless communication network (100), wherein the method is further comprises determining a position of the first device (104) or of a second device (106) that is moving relative to the access point (102), looking up a channel quality of the communication channel (112) that is assigned to the position, and outputting the channel quality.

Abstract: An anomaly detector (100) for detecting an abnormal activity in a telecommunications network. The anomaly detector (100) includes a receiver unit (102) configured to receive a plurality of network measurements (nm) in relation to the telecommunications network; a model-based mapping unit (104) configured to map the received plurality of network measurements (nm) via a machine-trained anomaly detection model (106) to an anomaly indicator (ai); and an output unit (108) configured to provide the anomaly indicator (ai), which indicates the abnormal activity in the telecommunications network.

Abstract: Various example embodiments are discloses. According to one example embodiment, a method may include sending a packet to both a relay station and a destination station in a wireless network, receiving a relay station acknowledgment (ACK) or negative acknowledgment (NACK) from the relay station during an ACK/NACK frame, and receiving a destination station ACK or NACK from the destination station during the ACK/NACK frame. The relay station ACK or NACK may either acknowledge or negatively acknowledge successful receipt of the packet by the relay station. The destination station ACK or NACK may either acknowledge or negatively acknowledge successful receipt of the packet by the destination station.
