Abstract: Disclosed herein is a multi-stage echo cancelation scheme. The disclosed embodiments include an apparatus and method for monitoring and canceling echoes greater than 25 dB in a coaxial cable plant. The method includes obtaining echo channel estimate coefficients from a cable node. The method determines a location and strength of each partial echo in an impulse response using the echo channel estimate coefficients. Optionally, the method determines a frequency response of each partial echo in the impulse response.

Abstract: Embodiments are provided for adjusting a transmission power level at a user equipment (UE). An embodiment method by a network includes sending, to the UE, a first indication for a transmission power level. The transmission power level is for a transmission from the UE to a base station. The method further includes sending a second indication for the transmission power to the base station. The UE receives the indication for the transmission power level, and applies the transmission power level on uplink from the UE to the base station. The UE is located between the base station and a radio node and transmits on uplink to the base station and the radio node.
