<p>A Base station adapted to transmit a power grant signal (ABS GRNT E-AGCH) to an individual user entity, granting (11) the individual user entity a power threshold of a given rank (SG) The transmission from user entities to the base station being performed by means of a retransmission scheme comprising at least acknowledge (ACK) and not acknowledge (NACK) signalling from the base station, wherein the base station being adapted to carry out the following steps of, evaluating (7, 7i) ) for a given period (5, 5ii) a current parameter ((E-DCH(SG),- S-NACK(SG)) indicative of the effective bit rate (7, 7i), by comparing the current parameter with a reference value (E_DSCH (SG-I), S_NACK_MAX), depending on the evaluation, the base station, decrementing (8) the rank (SG) of the power threshold, or allowing the rank (SG) of the power threshold to be incremented (10), the base station being adapted to limiting serving grants.</p> |
