A method for detecting interference in a system inal? Mbrico communication.

摘要

Method for determining the existence of interference in a wireless communication link, comprising: # (i) collecting values ​​RXLEV_ UL, RXLEV DL received power in uplink (UL) and downlink (DL); # (ii) use mentioned values ​​to estimate the power level of the receiver at the base station; # (iii) estimating, for each connection i in the radio link, the received power in UL, P {sup, i} {sub, RXLEV_UL}, and the received power in UL if conditions were the channel in FIGURA01 ** **; # (iv) calculating a parameter, P {sup, i} {sub, s}, which measures the difference between the values ​​* * FIGURA02 **; # (v) estimating the ratio of signal to noise ratio in the DL and UL in, R {sub, SNRI}; # (vi) estimating the joint probability density p (p {sup, i} {sub, s}, R {sub, SNRI} of pairs of values ​​p {sup, i} {sub, s} and R {sub, SNRI} within a time period of study; # (vii) analyzing the results to detect interference.
