A method and apparatus schedule uplink transmissions with reduced latency. A first transmission power of a first uplink transmission can be determined at a device based on a first set of higher layer configured power control parameters associated with a first TTI length. A higher layer can be higher than a physical layer. The first uplink transmission can span the first TTI length. The first TTI length can include a first number of symbols. A second transmission power of a second uplink transmission can be determined based on a second set of higher layer configured power control parameters associated with a second TTI length. The second uplink transmission can span the second TTI length. The second TTI length can include a second number of symbols. The second number can be different from the first number. The first uplink transmission can be transmitted in a subframe using the first transmission power. At least the second uplink transmission can be transmitted in the subframe using the second transmission power. The first uplink transmission and the second uplink transmission can overlap in time for at least one symbol duration.
