1. A method 100 of robust page indication (PI) detection by a user equipment (UE) 10 in a wireless communication network, comprising: accumulating a received bit sequence, of a known length, at a predetermined position within a frame of a page indication channel, to form a decision variable; measuring a factor affecting the probability of correctly detecting a page indication; if the measured factor indicates a high probability of correctly detecting the page indication, comparing the decision variable to a standard value of a PI threshold; if the measured factor indicates a low probability of correctly detecting the page indication, comparing the decision variable to a derived value of the PI threshold lower than the standard value; and determining that a page indication was received if the decision variable exceeds the PI threshold.
