Patent ID: 7916667

Claim:
A method for determining an RF Link Imbalance between an Uplink Path (UL Path) and a Downlink Path (DL Path) of an RF Link between a User Equipment (UE) and a NodeB in a 3G UMTS wireless network comprising: measuring Common Pilot CHannel (CPICH) Rx Power at a UE; determining the DL Path Loss from the UE side of the RF Link as CPICH_Tx_Power-CPICH Rx Power; determining the UL Path Loss from the UE side of the RF Link as UE Tx Power-NodeB Expected Rx Power; and determining RF Link Imbalance as UL Path Loss-DL Path Loss, wherein the step of determining the UL Path_Loss comprises estimating the NodeB_Expected Rx Power using the expected Noise Floor of the NodeB , the Receive Sensitivity of the NodeB on the Network side of the RF Link, the Processing Gain of a voice call, and the approximate target Signal to Interference ratio at the NodeB; and determining RF Link Imbalance as UL Path Loss-DL Path Loss.
