Abstract
Systems, apparatuses, and methods are described for wireless communications. A wireless device may distribute power for various transmission types based on a priority, which may be received from a base station.
Claims51
A method comprising:
- receiving, by a wireless device, one or more radio resource control messages comprising:
- first configuration parameters of at least one cell;
- and
- second configuration parameters associated with a random access procedure for beam failure recovery;
- after at least one beam failure on a first cell of the at least one cell, determining, based on the second configuration parameters, a first transmission power of a first preamble associated with the random access procedure for beam failure recovery;
- determining that a first configured transmission, of the first preamble, overlaps in time with a second configured transmission of a second preamble;
- determining an adjusted transmission power of the second preamble so that a total power, comprising the first transmission power and the adjusted transmission power, does not exceed a total allowable power;
- and
- transmitting, using the adjusted transmission power, the second preamble.
