1. A time division duplex (TDD) repeater comprising:
a first port;
a second port;
a controller configured to identify a maximum number of adjacent first direction subframes in one or more frames of a first direction signal based on a TDD uplink (UL)/downlink (DL) frame configuration of the first direction signal;
one or more amplification paths coupled between the first port and the second port; and
a signal detector, wherein the controller is configured to measure a power variance for the first-direction signal with the signal detector during the maximum number of adjacent subframes in the one or more frames in the first direction signal, and
wherein the repeater is configured to determine that an oscillation is occurring in the first-direction signal when the power variance is low; and
wherein the repeater is configured to determine that an oscillation is not occurring in the first-direction signal when the power variance is high.
