Abstract: A method for determining a Modulation and Coding Scheme (MCS) and power control includes determining an error rate of a communication channel between the UA and at least one of the base station and the RN. When the error rate is below a first threshold, the method includes at least one of increasing the MCS, and reducing a transmission power of the UA. When the error rate is above a second threshold, the method includes at least one of decreasing the MCS, and increasing a transmission power of the UA.
