  • Patent number: 9414332
    Abstract: A first signal is transmitted starting in a first subframe of a cell of a first cell group. A second signal is configured for transmission in a second subframe of a second cell group. Transmission of the second signal is dropped if a power value is more than an allowable transmission power. A calculation of the power value considers transmission power of the first signal and the second signal if the first subframe and the second subframe overlap in time with more than a first duration.

  • Patent number: 9386604
    Abstract: A wireless device receives control message(s) comprising parameters of a plurality of cell groups and a pathloss reference for each secondary cell. The wireless device transmits uplink signals in a first secondary cell in a secondary cell group. Transmission power of the uplink signals is determined employing a received power of the pathloss reference assigned to the first secondary cell. Timing of the uplink signals in the secondary cell group employs a synchronization signal on an active secondary cell in the secondary cell group as a timing reference.
