DISTRIBUTION OF DOWNLINK E-DCH POWER USAGE

摘要

The present invention relates to a method, a communication system and a Node-B (NB) in a communication system for distribution of downlink E-DCH power usage in a communication system. The system comprises at least one Node-B (NB) for enabling wireless communication with at least one user terminal (UE). The communication is 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) and the Node-B (NB). The Node-B (NB) comprises a HSDPA scheduler (HS-S) for scheduling the data rate for the DL data traffic via the HS-DSCH. It further comprises an EUL scheduler (EUL-S) for scheduling the maximum data rate for the UL data traffic via the E-DCH. The method is particularly characterized in that the Node-B (NB) estimates 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) sends 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.
