Abstract: A system is disclosed that includes a base station having a plurality of antennas a control unit which analyses pilot signals received from the terminal device at the plurality of antennas to obtain information about a wireless channel property of the wireless channel between the terminal device and the plurality of antennas. According to a method, a plurality of pilot signals is transmitted from the terminal device to the base station, and information about the wireless channel property of the wireless channel between the terminal device and the plurality of antennas of the base station is determined based on a predefined number of last recently transmitted pilot signals of the plurality of pilot signals from the terminal device. Based on the information about the wireless channel property, at least one parameter of the plurality of antennas is configured by the base station.

Abstract: A half-duplex radio device (100) generates a repetitive transmission of an uplink message to a base station (150) of the cellular network. The radio device (100) splits the repetitive transmission of the uplink message into a sequence of multiple transmit periods and configures at least one measurement gap between the transmit periods. In the transmit periods, the radio device (100) sends the repetitive transmission to the base station. In the at least one measurement gap configured between the transmit periods, the radio device (100) temporarily switches to receiving at least one downlink signal from the base station (150). Based on the received at least one downlink signal, the radio device (100) estimates a frequency error of a reference frequency source of the radio device (100).

Abstract: First reoccurring resources on a radio interface of a cellular network (100) are allocated and shared between communication devices (121-125) assigned to a first set (151). Second reoccurring resources on the radio interface are allocated and shared between communication devices (121-125) assigned to a second set (152). A control message is sent, the control message indicating the first reoccurring resources and the second reoccurring resources. The control message may optionally be sent employing a broadcast transmission (110).

Abstract: First reoccurring resources on a radio link of a cellular network are allocated to the first relaying channel. Second reoccurring resources on the radio link are allocated to a second relaying channel. The first reoccurring resources are shared between communication devices assigned to a first set; the second reoccurring resources are shared between communication devices assigned to a second set. The first reoccurring resources, in some embodiments, may be orthogonal to the second reoccurring resources.

Abstract: A radio device applies a carrier frequency for transmission of data between the radio device and a base station of a cellular network. Further, the radio device configures a measurement time interval in which the radio device temporarily switches from the transmission of data to receiving at least one broadcast signal conveying system information from the base station. Based on the received at least one broadcast signal, the radio device estimates an offset of the carrier frequency as applied by the radio device to a frequency of a carrier signal as received from the base station.

Abstract: The present disclosure relates to a method for operating a base station of a wireless communication network. Precoding information for concentrating a radio-frequency power of a transmitted radio-frequency signal to a group of terminal devices arranged in a sub area of a coverage area of the base station is determined and applied to an antenna array of the base station. A synchronization signal is transmitted from the base station to the group of terminal devices using the precoding information.
