Input power backoff signaling

A first wireless device configured to determine input power backoff (IBO) values used for wireless transmissions by a second wireless device, the first wireless device comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the first wireless device to:
• negotiate a set of IBO values that are mutually compatible to each of the first and second wireless devices;
• receive a wireless signal from the second wireless device;
• and
• determine an actual IBO value used by the second wireless device to transmit the wireless signal based at least in part on the negotiated set of IBO values.

A non-transitory computer-readable storage medium comprising instructions that, when executed by one or more processors of a first wireless device, cause the first wireless device to determine input power backoff (IBO) values used for wireless transmissions by a second wireless device by performing operations comprising:

• negotiating a set of IBO values that are mutually compatible to each of the first and second wireless devices;
• receiving a wireless signal from the second wireless device;
• and
• determining an actual IBO value used by the second wireless device to transmit the wireless signal based at least in part on the negotiated set of IBO values.

An apparatus for determining input power backoff (IBO) values used for wireless transmissions with a wireless device, the apparatus comprising:

• means for negotiating a set of IBO values that are mutually compatible to each of the apparatus and the wireless device;
• means for receiving a wireless signal from the wireless device;
• and
• means for determining an actual IBO value used by the wireless device to transmit the wireless signal based at least in part on the negotiated set of IBO values.
