    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.
