Patent abstract
A wireless device receives a control command to transmit a random access preamble on random access resources of a secondary cell in a secondary cell group. The wireless device receives a random access response providing an uplink grant to transmit an uplink packet. The wireless device computes the transmission power of the uplink packet employing, at least in part, a first parameter calculated by summation of: a power control value corresponding to a power control field in the uplink grant; and a total power ramp-up from the first transmission to the last transmission of the random access preamble.
