Patent ID: 8345613

Claim:
A method for grant violation detection in an enhanced uplink (UL) telecommunication system comprising at least one Node B (NB) for enabling wireless communication with at least one user terminal, the method comprising: establishing, with at least one first radio network controller (RNC), at least a first enhanced UL transport channel (E-DCH) enabling uplink data traffic with a certain data rate from the first user terminal (UE) at least to the first Node B (NB), the first E-DCH carrying data for at least one radio access bearer (RAB), performing at least a first downlink transmission including a first E-DCH channel scheduled grant to the first user terminal (UE), the scheduled grant defining a maximum data rate limit for the uplink data traffic via the first E-DCH, calculating, with the first user terminal (UE), a scheduled data rate for the uplink raffle via the first E-DCH from the received first E-DCH channel scheduled grant, transmitting, from the first user terminal (UE), the uplink data traffic on the first E-DCH with the calculated scheduled data rate, detecting, at the Node B (NB), the scheduled data rate on which the first user terminal (UE) transmits, and in response to detecting that the scheduled data rate is higher than the maximum data rate defined by the first E-DCH channel scheduled grant, performing with the Node B at least a second following downlink transmission that includes the first E-DCH channel scheduled grant, wherein the second following downlink transmission is transmitted by the Node B (NB) with a higher power level than the first downlink transmission.
