Abstract
Systems, apparatuses, and methods are described for wireless communications. A base station may transmit indications of target received powers for a random access procedure and a beam failure recovery procedure. A wireless device may transmit a random access preamble and a beam failure recovery preamble using different transmission powers based on the indications of target received powers.

A method comprising:
- receiving, by a wireless device, at least one configuration parameter for pathloss associated with a preamble transmission via a cell, wherein the at least one configuration parameter is associated with a candidate signal;
- and
- transmitting, via a random access channel and using a transmission power that is based on the at least one configuration parameter for pathloss, a preamble for beam failure recovery associated with the cell.
A method comprising:
- transmitting, by a base station, at least one configuration parameter for pathloss associated with a preamble transmission via a cell, wherein the at least one configuration parameter is associated with a candidate signal;
- and
- receiving, via a random access channel, a preamble for beam failure recovery associated with the cell, wherein a transmission power for the preamble for beam failure recovery is associated with the at least one configuration parameter.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the wireless device to:
- receive at least one configuration parameter for pathloss associated with a preamble transmission via a cell, wherein the at least one configuration parameter is associated with a candidate signal;
- and
- transmit, via a random access channel and using a transmission power that is based on the at least one configuration parameter for pathloss, a preamble for beam failure recovery associated with the cell.
A base station comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the base station to:
- transmit at least one configuration parameter for pathloss associated with a preamble transmission via a cell, wherein the at least one configuration parameter is associated with a candidate signal;
- and
- receive, via a random access channel, a preamble for beam failure recovery associated with the cell, wherein a transmission power for the preamble for beam failure recovery is associated with the at least one configuration parameter.

- receive at least one configuration parameter for pathloss associated with a preamble transmission via a cell, wherein the at least one configuration parameter is associated with a candidate signal;
- and
- transmit, via a random access channel and using a transmission power that is based on the at least one configuration parameter for pathloss, a preamble for beam failure recovery associated with the cell.

A system comprising:
- a wireless device;
- and
- a base station,
- wherein the base station is configured to:
- transmit at least one configuration parameter for pathloss associated with a preamble transmission via a cell, wherein the at least one configuration parameter is associated with a candidate signal, and
