Abstract
In an embodiment, a method includes identifying, by a first device, a level of degradation. The method also includes transmitting, by the first device during a communication phase, a first signal with a first signal quality based on the level of degradation. The method further includes transmitting, by the first device during a second communication phase, a second signal with a second signal quality. The second signal quality may be greater than the first signal quality.
Claims21
A method, comprising:
- transmitting, by a first device to a second device, a proposed degradation level;
- receiving, by the first device from the second device an acknowledgment responsive to the proposed degradation level;
- setting a level of degradation level to the proposed degradation level after receiving the acknowledgement;
- transmitting, by the first device during a first communication phase, a first signal with a first signal quality based on the level of degradation;
- and
- transmitting, by the first device during a second communication phase, a second signal with a second signal quality, wherein the second signal quality is greater than the first signal quality.
