    Abstract: A base station receives RRC message(s) comprising configuration parameters for a LAA cell. The configuration parameters comprise one or more SRS parameters. Configuration parameters of cells are transmitted to a wireless device. The cells are grouped into timing groups. The cells are grouped into control channel groups comprising: a primary control channel group; and a secondary control channel group comprising a control secondary cell with a secondary control channel received from the wireless device. The control secondary cell is in a first timing group of the timing groups. In response to expiration of a time alignment timer of the first timing group: transmission of downlink shared channel transport blocks to the wireless device via a first secondary cell in the secondary control channel group are stopped; and transmission of downlink multicast channel transport blocks to the wireless device via the first secondary cell is continued.

    Abstract: A wireless device receives, during a first time interval, a command indicating activation of a physical uplink control channel (PUCCH) secondary cell of a timing advance group (TAG). A timing advance for the TAG is received. Transmission of valid channel state information is started via the PUCCH secondary cell during a second time interval occurring a first quantity of time intervals after the first time interval. The first quantity is based on a delay from receipt of the command until the wireless device applies the timing advance to uplink transmissions via the TAG.

    Abstract: A wireless device initiates a random access procedure for parallel transmissions of random access preambles for beams of a cell. A determination is made that a first calculated transmit power exceeds a first power value. The first calculated transmit power comprises transmission powers corresponding to the parallel transmissions of the random access preambles. In response to the determination, a first transmission of at least one first random access preamble of the random access preambles is dropped based on at least one first pathloss value corresponding to the first transmission being greater than at least one second pathloss value corresponding to a second transmission of at least one second random access preamble of the random access preambles. The at least one second random access preamble of the random access preambles is transmitted by the wireless device.
