Abstract

The disclosure provides a communication system that includes sensors, a plurality of components, and processors. The sensors receive measurements related to a state of the communication system. The processors receive an indication of an amount of received power at a remote communication system and estimate a state of the plurality of components based on the received one or more measurements and the received indication. Using the indication and the estimated state, the processors determine whether the amount of received power is likely to fall below a minimum received power within a given time interval. When it is likely, the processors select an adjustment technique of a plurality of adjustment techniques for adjusting a data rate of the outbound signal and adjust a given component of the communication system using the selected adjustment technique to change the data rate of the outbound signal.

Dependent claims

A first communication device comprising:

a transmitter configured to transmit a signal to a second communication device over a communication link, the signal carrying data;
and
one or more processors configured to:
receive, from the second communication device, an indication of an amount of received power for the communication link over a first time interval;
predict, based on the received indication, that the amount of received power will fall below a minimum received power in a second time interval;
after the amount of received power is predicted to fall below the minimum received power in the second time interval, select an adjustment technique for changing the data rate of the signal transmitted by the transmitter, wherein the selected adjustment technique allows the signal to continue transmitting the data over the communication link;
and
adjust the data rate of the signal using the selected adjustment technique.

5 more elements

A method of adjusting a transmitted communication signal, the method comprising:

receiving, by one or more processors of a first communication device from a second communication device, an indication of an amount of received power for a communication link over a first time interval;
predicting, by the one or more processors based on the received indication, that the amount of received power will fall below a minimum received power in a second time interval;
after the amount of received power is predicted to fall below the minimum received power in the second time interval, selecting, by the one or more processors, an adjustment technique for changing a data rate of a signal transmitted by a transmitter of the first communication device to the second communication device, wherein the selected adjustment technique allows the signal to continue transmitting data over the communication link;
and
adjusting, by the one or more processors, the data rate of the signal using the selected adjustment technique.

2 more elements

A non-transitory, tangible computer-readable storage medium on which computer readable instructions of a program are stored, the instructions, when executed by one or more processors of a first communication device, cause the one or more processors to perform a method, the method comprising:

receiving, from a second communication device, an indication of an amount of received power for a communication link over a first time interval;
predicting, based on the received indication, that the amount of received power will fall below a minimum received power in a second time interval;
after the amount of received power is predicted to fall below the minimum received power in the second time interval, selecting an adjustment technique for changing a data rate of a signal transmitted by a transmitter of the first communication device to the second communication device, wherein the selected adjustment technique allows the signal to continue transmitting data over the communication link;
and
adjusting the data rate of the signal using the selected adjustment technique.
