1. Method for distribution of downlink E-DCH power usage in a communication system comprising at least one Node-B (NB) (11) enabling wireless communication with at least one user terminal (UE) (15),the communication being enabled via an enhanced dedicated transport channel (E-DCH) and one high speed downlink shared channel (HS-DSCH) for uplink (UL) and downlink (DL) data traffic between the user terminal (UE) (15) and the Node-B (NB) (11),the Node-B (NB) (11) comprising a HSDPA scheduler (HS-S) for scheduling the data rate for the DL data traffic via the HS-DSCH and an EUL scheduler (EUL-S) for scheduling the maximum data rate for the UL data traffic via the E-DCH,characterized in thatthe Node-B (NB) (11) estimating (403,404,603,604,608,809,906,106,111) the power consumption and/or the corresponding transmission time for at least one forthcoming E-DCH DL transmission on at least one E-DCH physical channel,the Node-B (NB) (11) sending (403,405,603,609,811,908,108,112) the estimated power consumption and/or the corresponding transmission time information to the HSDPA scheduler (HS-S) prior to the E-DCH DL transmission.
