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.
Claims20
A device comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor configured to:
- transmit, via the transceiver, a message indicating a proposed degradation level;
- receive, via the transceiver, an acknowledgement message after communicating the proposed degradation level;
- transmit, via the transceiver, a first signal having a first signal quality based on the proposed degradation level;
- and
- transmit, via the transceiver, a second signal having a second signal quality, wherein the second signal quality is greater than the first signal quality.

A device comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor configured to:
- receive, via the transceiver, a message indicating a proposed degradation level;
- in response to receiving the message, transmit, via the transceiver, an acknowledgement message;
- receive, via the transceiver, a first signal having a first signal quality based on the proposed degradation level;
- and
- receive, via the transceiver, a second signal having a second signal quality greater than the first signal quality.

A vehicle comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor configured to:
- receive, via the transceiver, a message indicating a proposed degradation level;
- in response to receiving the message, transmit, via the transceiver, an acknowledgement message;
- receive, via the transceiver, a first signal having a first signal quality based on the proposed degradation level;
- receive, via the transceiver, a second signal having a second signal quality greater than the first signal quality;
- determine whether the second signal is authentic based on a comparison of the first signal and the second signal;
- and
- initiate unlocking the vehicle based on determining that the second signal is authentic.
