Abstract
The present invention discloses a method and system for enabling efficient reduction of TFCs in the TFCS to achieve desired transmission, while remaining within desired power and data requirements. Upon the UE transmission power requirement exceeding the maximum or allowable transmission power the MAC shall be informed for subsequent TFC selection of all TFCs that currently exceed this limit. The UE will then chose the TFC with the next lower transmission power requirement and the sequence will continue until an acceptable TFC is determined. The present invention also enables the replacement of the TFCs in the TFCS and advanced determination of non-supported TFCs. The TFCs that require transmission power greater then the maximum or allowed UE transmission power shall be determined continuously in every TTI, not just in TTIs where the maximum power has been exceeded.
