Abstract
A method and a serving NodeB for adjusting transmit power of a User Equipment (UE) having multiple transmitter chains to reduce relative phase discontinuity (RPD) between a Sounding Reference Signal (SRS) and a Physical Uplink Shared Channel (PUSCH). The NodeB receives from the UE, an RP characteristic of the UE and, based on the RP characteristic, selects an SRS or PUSCH transmit power level for the UE so as to reduce the RPD. The NodeB instructs the UE to set the SRS or PUSCH transmit power level to the level selected by the NodeB.
