  • Signal Power Management in a Multicarrier Wireless Device
    Publication number: 20160100372
    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.

  • Multicarrier Communications Employing Time Alignment Timers
    Publication number: 20160088622
    Abstract: A wireless device is configured with a primary cell group and a secondary cell group. When a first time alignment timer of the primary cell group expires, for a cell in the wireless device, the wireless device stops uplink transmission of HARQ feedback, uplink transport blocks, and channel state information while allowing uplink transmission of random access preamble(s). When a second time alignment timer of the secondary cell group expires and the first time alignment timer is running, for an activated cell in the secondary cell group, the wireless device stops transmission of uplink transport blocks, and continues downlink transmission of HARQ feedback and channel state information.
