A method for indicating performance enhancements in a wireless
transmit/receive unit (WTRU) to a user in a wireless communication system
begins with operating a radio link to the WTRU with a performance
enhancement active. The operating results with the performance
enhancement active are measured. The radio link to the WTRU is operated
with the performance enhancement inactive and the operating results with
the performance enhancement inactive are measured. The measurements with
the performance enhancement active and the performance enhancement
inactive are compared, and a display indicator on the WTRU is prepared
and displayed, showing the performance difference of the WTRU when the
performance enhancement is active and inactive.
