Abstract: A wireless base station controls User Equipment (UE) where a wireless repeater chain repeats wireless signaling between the UE and the wireless base station. The wireless base station receives the wireless signaling transferred by the UE and determines signaling latency between the UE and the wireless base station. The wireless base station processes the signaling latency to determine a wireless repeater hop count between the UE and the wireless base station. The wireless repeater hop count indicates a number of wireless repeaters in the wireless repeater chain that repeat between the UE and the wireless base station. The wireless base station determines a UE instruction based on the wireless repeater hop count. The wireless base station transfers the UE instruction to the UE over the wireless repeater chain.
