Abstract

A wireless communication network to control Radio Frequency (RF) measurement reporting for User Equipment (UE). A wireless base station receives initial wireless data transferred by the UE. The wireless base station processes wireless data from the UE to detect a repeater chain repeating the wireless data between the UE and the wireless base station and to determine a wireless signal metric. The wireless base station processes the wireless signal metric based on the detection of the repeater chain to select a new RF measurement reporting frequency for the UE. The wireless base station transfers an instruction to the UE indicating the new RF measurement reporting frequency and receives subsequent wireless data transferred by the UE using the new RF measurement reporting frequency.

Claims
