Abstract
Methods and apparatuses are provided for obtaining downlink or uplink signal characteristics of at least one access point in a network. The signal characteristics may be obtained through user equipment receiving the signal characteristics, through the at least one access point, or through another access point. Frequency or timing offset between two or more access points may be determined based on the obtained signal characteristics, where the frequency or timing offset may be handled through post processing. For example, a clock servo may be controlled or adjusted in response to the determined offset, the absolute frequency of a master network oscillator may be calibrated, traffic anomalies within the network may be detected and corrected, and/or respective clocks of the two or more access points may be synchronized.
