Abstract
A method in a wireless communication device comprises determining transmission powers for at least two clusters, wherein each cluster includes at least one physical resource block (RB), determining a difference in a characteristic of the transmission powers determined for the at least two clusters, and varying a transmit power allocated to at least one cluster if the difference in the characteristic exceeds a power spread threshold, wherein the power allocated to each cluster is a function of pathloss between the wireless communication device and a serving base station.

9. A method in a wireless communication device, the method comprising:
-
determining a difference in a power characteristic for at least two clusters, wherein each cluster includes at least one physical resource block; determining a power reduction that is bounded by a maximum power reduction (“
MPR”
) limit that is dependent on a power attribute, wherein the power attribute is the difference in the power characteristic for the at least two clusters;determining PCMAX based on the power reduction; and based on PCMAX, determining an uplink transmit power and a power headroom. - View Dependent Claims (10, 12, 13, 14, 15, 16)
