Abstract:
1. A method for optimizing a Transport Format Combination (TFC) selection procedure processed by a user equipment (UE) in an uplink communication in a mobile telecommunication network, wherein a TFC procedure during a current TTI (Transmission Time Interval) is performed in a function of: a remaining power measured after the TFC procedure is performed in a past TTI, as a previous TTI of the current TTI; a power for transmitting E-DCH (Enhanced Dedicated Control Channel) channels in the past TTI; and a minimum specified power for transmitting the E-DCH channels in a next TTI, as a subsequent TTI to the current TTI, wherein a first TFC for DCH (Dedicated Control Channel) channels is selected based on a condition of a gain factor ratio of the DCH channels in relation to a maximum gain power ratio of the DCH channels in which the minimum specified power for transmitting the, E-DCH channels having been considered, and a second TFC for the E-DCH channels is selected based on a condition of a gain factor ratio of the, E-DCH channels in relation to a maximum authorized gain factor ratio of the E-DCH channels which is computed based on the selected first TFC; wherein the pain factor ratio of the DCH channels is expressed by (β
