Apparatus and method of improving the overall decision quality of the F-DPCH channel

A method of transmit power control, comprising:

• receiving a downlink (DL) transmit power control (TPC) command on a Fractional-Dedicated Physical Channel (F-DPCH) from a serving base station;
• determining a scaling adjustment for a DLTPC rejection threshold for the serving base station based on a difference between channel conditions of multiple base stations including the serving station;
• adjusting the DLTPC rejection threshold for the serving base station based on the determined scaling adjustment;
• detecting an extreme channel condition for the F-DPCH from the serving base station, wherein detecting the extreme channel condition includes identifying a channel condition parameter and determining that the channel condition parameter meets a crisis mode threshold that is different from the adjusted DLTPC rejection threshold;
• adjusting the scaling adjustment for the DLTPC rejection threshold for the serving base station based on detecting the extreme channel condition for the F-DPCH from the serving base station;
• determining a crisis mode DLTPC rejection threshold by further adjusting the adjusted DLTPC rejection threshold for the serving base station based on the adjusted scaling adjustment;
• and
• rejecting or accepting the DLTPC command from the serving base station based on the crisis mode DLTPC rejection threshold.

An apparatus of wireless communication, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, wherein the at least one processor is configured to:
• receive a downlink (DL) transmit power control (TPC) command on a Fractional-Dedicated Physical Channel (F-DPCH) from a serving base station and a non-serving base station;
• determine a scaling adjustment for a DLTPC rejection threshold for the non-serving base station based on a difference between a first DL signal-to-inference ratio (SIR) estimate of the non-serving base station and a second DL SIR estimate of the serving base station;
• adjust the DLTPC rejection threshold for the non-serving base station based on the determined scaling adjustment;
• and
• reject or accepting the DLTPC command from the non-serving base station based on the adjusted DL TPC rejection threshold.
