    Abstract: A device controls each antenna to transmit at least one first UL pilot signal and to receive, for each first UL pilot signals DL data encoded according to the respective first UL pilot signal. The receive properties of the DL data are combined and a second UL pilot signal is determined based on the combined receive properties. The second UL pilot signal is repeatedly transmitted. The techniques may be applied in a massive multi-input multi-output scenario.

    Abstract: The present invention relates to a method for operating a wireless communication system. The wireless communication system comprises a base station and a terminal. The terminal comprises a plurality of antenna elements and provides at least two antenna array configurations comprising a first antenna array configuration comprising at least two antenna elements having same radio transmission characteristics and a second antenna array configuration comprising at least two antenna elements having different radio transmission characteristics. According to the method, a selection process for selecting and an antenna array configuration of the at least two antenna array configurations is triggered and for each of the at least two antenna array configurations a corresponding figure of merit is determined. The corresponding figure of merit is determined based on corresponding pilot signals received from the base station via the corresponding antenna array configuration. Depending on the figures of merit, an antenna array configuration is activated.

    Abstract: Method carried out in a radio terminal for playing streaming media, which terminal includes a modem for connecting to a radio network, and a data streaming client including a streaming data buffer for receiving streaming data from a streaming data server through the radio network, the method comprising transferring data buffer size information from the streaming client to the modem; signaling the network, by means of the modem, to indicate streaming service initiation and data buffer size; buffering media data of a streaming media file received through the network according to a buffer scheme adapted dependent on the data buffer size; playing streaming media generated from buffered media data; and signaling the network, by means of the modem, to indicate streaming service termination. A buffer filling signal may be received from the network, which includes a recommendation of a suitable instance for buffer filling, wherein the buffer scheme may be determined dependent on the received signal.

    Abstract: A wireless communication device (100, 100′) receives resource allocation information from a wireless communication network. The resource allocation information indicates at least one condition for utilization of a set of resources allocated to device-to-device communication. Depending on the at least one condition, the wireless communication device (100, 100′) controls utilization of the set of resources for device-to-device communication between the wireless communication device (100, 100′) and a further wireless communication device (100, 100′).

    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: Operating a cellular multiple-input and multiple-output system including a first device having an antenna array having a plurality of antennas, and a second device having at least two antennas includes a same uplink pilot signal broadcast from each antenna of the second device, and received at the antenna array of the first device. Depending on the received same uplink pilot signal, a first set of first device receiving parameters for the antenna array is determined. From each antenna of the at least two antennas of the second device, a corresponding uplink pilot signal is sent and received at the antenna array of the first device using the first set of first device receiving parameters. At the first device, for each received uplink pilot signal, a corresponding second set of first device receiving parameters is determined depending on the plurality of received orthogonal uplink pilot signals.
