Abstract: A method of downloading video contents from a content server to a client through a base station of a wireless communication network is provided. Each video content includes a sequence of encoded video frames. The method includes having the content server send a video content in a sequence of data packets, each data packet including data corresponding to at least one portion of an encoded video frame, and having a proxy server at the base station classify each data packet according to the type of video frame it correspond to. The method also includes having a scheduler at the base station assign radio resources for the transmission of the data packets to the client based on the classification carried out by the proxy server, and transmitting the data packets to the client by exploiting the radio resource assignment carried out by the scheduler.

Abstract: A method for managing a full duplex mobile telecommunication network includes providing a coordination unit of a set of base stations, and having the coordination unit group a plurality of user equipment served by said base stations to form corresponding user groups. Each user group includes a group of user equipment which are close to each other by an extent such to cause potential user equipment to user equipment interference. The method also includes having the coordination unit allocate radio resources for at least one between transmissions from user equipment to base stations, and transmissions from base stations to user equipment. The method further includes having each base station carrying out at least receiving transmissions from at least one served user equipment, and sending transmissions to at least one served user equipment by exploiting the allocated radio resources.

Abstract: A method for managing a cellular network. The cellular network includes a plurality of base stations each one configured to exchange data with user equipment located in a corresponding cell by exploiting a downlink data channel and an uplink data channel according to a frequency division duplexing scheme. The method includes: having a first base station exchanging coordination information with a second base station, the coordination information being related to at least one among channel state condition and resources allocation to user equipment, the having the first base station exchanging coordination information with the second base station including: transmitting the coordination information from the first base station to the second base station exploiting a portion of the downlink data channel.

Abstract: A method is proposed of arranging, in a mobile communication network, transmission of data between user equipment and at least one base station including a central unit and at least one remote unit associated therewith. The method includes at a transmitting side including the remote unit or the central unit, quantizing the data according to a quantization bit number, and transmitting, over a fronthaul link between the transmitting side and a receiving side including the central unit or the remote unit, respectively, the quantized data to the receiving side. The method further includes, at the central unit: determining the quantization bit number, wherein the determining including varying in time the quantization bit number according to network information available at the central unit, and communicating to the at least one remote unit the determined quantization bit number.

Abstract: A method is proposed of arranging, in a mobile communication network, transmission of data between user equipment and a base station including a central unit and at least one remote unit associated therewith. The data includes information data and, associated with the information data, first control data substantially time-varying over a scheduling time period, and second control data substantially time-unvarying over the scheduling time period. The method includes at the central unit side, transmitting the information data and the first control data to the at least one remote unit, and at the at least one selected remote unit side, receiving the information data and the first control data from the central unit, generating the second control data, combining the generated second control data with the received information and first control data into the data, and transmitting the data to a selected user equipment.

Abstract: A wireless communication network including a first transceiver station for transmitting first signals over a first area coverage and over a first transmission bandwidth, and a second transceiver station selectively activatable/de-activatable. The second transceiver station is operable to broadcast, when de-activated, a beacon signal identifying the second transceiver station, the beacon signal having a beacon frequency at edges of the first transmission bandwidth. The beacon signal is detectable by a user equipment for inferring presence of the second transceiver station. The first transceiver station is configured to receive a response signal from a user equipment based on the detected beacon signal, and to schedule activation of the second transceiver station based on the received response signal.
