1. A cellular device, comprising:
processing circuitry; and
communication circuitry coupled to the processing circuitry and configured to:
request a power reduction to a cellular network node using a power back-off (P-MPR);
receive an allocation from the cellular network node;
during an allocated slot during the allocation, send a radio resource control (RRC) signal that includes the P-MPR;
in response to the RRC signal, receive an indication of how to reduce power; and
in response to receiving the indication, reduce power consumption according to the indication.
