Multi-cluster uplink transmission in wireless communication network

摘要

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.
