Abstract
Methods and apparatus for computing measurement metrics in a wireless communications network are provided. One example method generally includes obtaining a channel impulse response (CIR) from one or more reference signals (RSs) transmitted from one or more antennas of a base station (BS); calculating an absolute square per element of the CIR to generate channel energy response (CER) elements; calculating a threshold value based on a noise variance estimated from a portion of the CER elements; selecting CER elements that exceed the threshold value; and computing a reference signal received power (RSRP) value based on the selected CER elements.
