Abstract: Methods and apparatus for resuming radio channel measurements and estimations after an interruption in reception. In one exemplary embodiment of the present disclosure, an adaptive solution is provided for channel estimation based at least in part on the reception interruption duration. In one variant, an LTE UE determines a windowing length and/or “shape” for a time domain channel estimation algorithm based on at least the interruption duration. In an alternate variant, an LTE UE determines the interpolation coefficients for a filter based on the interruption duration.
