A process for allowing a User Equipment (UE) in a wireless communication network to control the HSDPA downlink data rate received from a NodeB, said UE successively receiving blocks of data having a predetermined size (N), involving the steps of: —receiving (10) one block of data; —determining (20) the size N associated to said block of data; The process further includes the steps of: —comparing (30) the size N of said block with at least a first predetermined threshold (N1); —if the size N shows to be superior than said first threshold (N1), execute the following steps: —storing (40) said block; —issuing (50) a NACK message to said NodeB; —accessing (60) a predetermined Look-Up-Table (LUT) with the value of N1 as an input and extracting a corresponding CQI value (CQI_LUT); —reporting (70) the CQI being the minimum between the CQI measured by the UE and said CQI_LUT value to said NodeB.
