Abstract:
A first wireless device including a receiver, a signal strength module, a path loss module, and a control module. The receiver receives a first signal from a second wireless device. The first signal includes an indication of a first power at which the second wireless device transmits the first signal. The signal strength module estimates a first signal strength of the first signal. The path loss module estimates a path loss associated with a communication path between the first wireless device and the second wireless device based on the first power at which the second wireless device transmits the first signal and the first signal strength of the first signal received from the second wireless device. The control module controls a second power at which the first wireless device transmits data based on the path loss associated with the communication path between the first wireless device and the second wireless device.
