Abstract: According to some embodiments, a secondary network node detects a first data transmission of media content from a primary network node to a first wireless device. The first data transmission has a first data quality description D(n1) and a first transport format T(k1). The secondary network node selects a second data quality description D(n2′) and a second transport format T(k2′) for a second data transmission. The second data quality description D(n2′) and second transport format T(k2′) differ from the first data quality description D(1) and first transport format T(k1), respectively. The secondary network node transmits the second data transmission to a second wireless device according to the second data quality description D(n2′) and the second transport format T(k2′). The second data transmission includes at least a portion of the media content.

Abstract: A mobile communication system comprises: a user terminal configured to receive a desired wave signal being a signal from a serving cell to the user terminal and an interference wave signal being a signal to another user terminal; and a base station configured to manage the serving cell. The base station includes a base station-side control unit configured to superpose an interference replica signal corresponding to the interference wave signal on the desired wave signal so as to cancel the interference wave signal received by the user terminal. The base station-side control unit is configured to transmit a predetermined signal corresponding to a first reference signal included in the interference wave signal. The user terminal includes a terminal-side control unit configured to derive first received power under a situation where the interference replica signal is superposed on the desired wave signal on the basis of at least one of the first reference signal and the predetermined signal.

Abstract: The present disclosure provides a method and apparatus for communicating data packets in a cloud cell. In one embodiment, a network node from which data packets are received is identified by the BS. If the data packets are received from a data gateway, a network node to which the data packets to be sent is identified. If the data packets are to be sent to a slave BS, partial processing is performed on the data packets by the master BS. Furthermore, partially processed data packets are transmitted to the slave BS so that the slave BS performs complete processing on the partially processed data packets and transmits the completely processed data packets to the MS. If the data packets are to be sent to the MS, then complete processing of the data packets is performed by the BS and transmitted to the MS.

Abstract: A method and a base station are provided. The base station obtains a first path gain of a cellular radio link to a first wireless device, a second path gain of a cellular radio link to a second wireless device and a third path gain of a Device-to-Device radio link between the first wireless device and the second wireless device. When the first, second and third path gains satisfy a threshold condition, the base station instructs the second wireless device to apply network coding on first data transmitted from the first wireless device and to transmit a network coded form of the first data. The base station receives a radio signal with the first data transmitted from the first wireless device and uses the network coded form of the first data transmitted by the second wireless device for decoding the first data.
