1. A method comprising:
- receiving, by a wireless device, one or more messages comprising configuration parameters of a plurality of cells;
determining a total transmission power for transmission of uplink signals in a subframe of a plurality of subframes and via the plurality of cells;
determining, employing a transmit power scaling factor, a transmission power value of an uplink signal of the uplink signals in response to the total transmission power exceeding a first value so that an updated total transmission power does not exceed the first value, wherein;
an uplink transmission burst transmitted during the plurality of subframes comprises the uplink signal; and
the transmit power scaling factor of the uplink signal depends on a subframe position of the subframe in the plurality of subframes of the uplink transmission burst; and
transmitting the uplink signal in the subframe and with the transmission power value.

Abstract
A wireless device receives from a base station one or more messages comprising configuration parameters of a plurality of cells. The plurality of cells comprising one or more first cells of a first type and one or more second cells of a second type. The wireless device determines one or more transmission powers. The wireless device transmits, via one or more cells, one or more signals employing the one or more transmission powers.

11. A wireless device comprising:
-
one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to; receive one or more messages comprising configuration parameters of a plurality of cells; determine a total transmission power for transmission of uplink signals in a subframe of a plurality of subframes and via the plurality of cells; and determine, employing a transmit power scaling factor, a transmission power value of an uplink signal of the uplink signals in response to the total transmission power exceeding a first value so that an updated total transmission power does not exceed the first value, wherein; an uplink transmission burst transmitted during the plurality of subframes comprises the uplink signal; and the transmit power scaling factor of the uplink signal depends on a subframe position of the subframe in the plurality of subframes of the uplink transmission burst; and transmit the uplink signal in the subframe and with the transmission power value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
