Abstract:
A telecommunication system comprises a radio network controller (RNC), and a Node-B (NB) for enabling wireless communication with a user terminal (UE). The RNC establishes an enhanced dedicated transport channel (E-DCH) which enables uplink data traffic with a determined maximum data rate from the user terminal (UE) to the NB. The RNC further establishes a high speed DL shared channel (HS-DSCH) which enables downlink data traffic with a determined maximum data rate from the NB to the user terminal. The NB comprises a HSDPA scheduler (HS-S) scheduling the data rate for the DL data traffic via the HS-DSCH and a EUL scheduler (EUL-S) scheduling the maximum data rate for the UL data traffic via the E-DCH. The NB exchanges data rate information between the HS-S and the EUL-S. Furthermore, the NB monitors the quotient (Q) between DL data rate and the UL data rate. When Q fulfils determined traffic conditions the HSDPA scheduler (HS-S) and/or the EUL scheduler (EUL-S) changes the allocation and/or the priority handling of the UL and/or the DL resources.
