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.

Abstract: The present invention relates to a method for grant violation detection in an enhanced uplink (UL) telecommunication system. According to the method a radio network controller (RNC) establishes a first enhanced UL transport channel (E-DCH) which enables uplink data traffic with a certain data rate from a user terminal UE at least to a first base station. At least a first downlink transmission is performed to the user terminal UE including a first E-DCH. A Node B NB detects the scheduled data rate on which the user terminal UE transmits and further controls if the scheduled data rate detected is higher than the maximum data rate defined by the first E-DCH channel scheduled grant. If this is the case the Node B NB performs at least a second following downlink transmission including the first E-DCH channel scheduled grant.

Abstract: A method for power control in an enhanced uplink telecommunication system is disclosed. The power for an uplink DPCCH in a first E-DCH is controlled by a base station. The base station and a user calculate power for an E-DPDCH in the first E-DCH based on a power offset configuration and absolute grant provided by the base station. The user terminal transmits the uplink data traffic on the first E-DCH with the controlled DPCCH power and the calculated E-DPDCH power. When the base station and the user terminal detect that the E-DPDCH absolute grant is different from a grant threshold, the base station changes a SIR target value. The first base station and the first user terminal compensate the change by recalculating the E-DPDCH power, reflecting both the changed DPCCH power resulting from the changed SIR target value and the improvement due to optimized channel estimation.

If the first TB is a discontinuous transmission frame (DTX), the base station resets a decoding attempt counter and prepares the first and second base stations for a new, second TB.

Abstract: The downlink transmit powers of base stations involved in a diversity handover communication with a mobile station are controlled to minimize base station power “drift.” A downlink reference power level is determined based on detected, current transmit power levels of the diversity handover base stations. One or more power offsets is determined for one or more of the base stations based on signal quality measurements made by the mobile station. The reference power level and power offset(s) are used to selectively regulate an adjustment to the transmit power levels of the diversity handover base stations. The general reference power is transmitted at a first, relatively high frequency to the diversity handover base stations by embedding it in a user data frame. In that way, the signal processing load is kept to a minimum despite the higher transmission rate.

Abstract: A power control system method for controlling the downlink (DL) transmit power from a base station (BS) to a mobile station (MS) in a cellular telecommunications network. A power balancing value &Dgr;P is divided into a number of smaller correction implements which are distributed over a plurality of spaced apart slots for DL power control. For example, if it is desired to correct DL transmit power by six dB, a total of six different correction values of one dB each may be implemented with adjacent ones of the correction values being spaced apart by a number of slots. The distribution or spreading of DL transmit power corrections over a period of time results in a plurality of smaller corrections as opposed to one or a few large corrections, thereby reducing potential adverse effects on the inner loop power control of the network.
