Abstract: Device-to-device (D2D) transmissions by a wireless device may interfere with base station reception of other signals. To mitigate this interference, the wireless device estimates the path loss between itself and the base station. The path loss and the current D2D transmission power level are used to estimate the amount of interference the base station is experiencing as a result of the D2D transmissions from the wireless device. Based on the estimated interference experienced by the base station, the wireless device increases the robustness of the MCS being used and decreases the transmission power level by a corresponding amount. By decreasing the D2D transmission power level, less interference will be experienced by the base station. By increasing the robustness of the MCS, the impact of the reduced D2D transmission power level is mitigated.
