Power control techniques for a communication system that includes a repeater

A method of wireless communication performed by a repeater that relays communications between a first communication device and a second communication device, comprising:

• determining one or more power configuration parameters associated with the repeater;
• transmitting the one or more power configuration parameters from the repeater to a controlling node, wherein the one or more power configuration parameters transmitted from the repeater to the controlling node comprise a power headroom parameter associated with the repeater, a current transmit power parameter associated with the repeater, or a current gain setting value associated with the repeater;
• receiving, at the repeater from the controlling node, gain configuration information determined for the repeater based on the power headroom parameter associated with the repeater, the current transmit power parameter associated with the repeater, or the current gain setting value associated with the repeater;
• receiving a communication from the first communication device;
• determining a gain value for the repeater based on the gain configuration information;
• applying the gain value for the repeater to the received communication to create a gain adjusted communication;
• and
• transmitting the gain adjusted communication from the repeater to the second communication device.

A method of wireless communication performed by a controlling node that communicates with a repeater, comprising:

• receiving, at the controlling node from the repeater, one or more power configuration parameters associated with the repeater, wherein the one or more power configuration parameters received at the controlling node from the repeater comprise a power headroom parameter associated with the repeater, a current transmit power parameter associated with the repeater, or a current gain setting value associated with the repeater;
• determining gain configuration information for the repeater based on the power headroom parameter associated with the repeater, the current transmit power parameter associated with the repeater, or the current gain setting value associated with the repeater;
• and
• transmitting the gain configuration information from the controlling node to the repeater.

A controlling node that communicates with a repeater, comprising:

• a processor;
• and
• a memory coupled with the processor, wherein the memory includes instructions executable by the processor to cause the controlling node to:
• receive, at the controlling node from the repeater, one or more power configuration parameters associated with the repeater, wherein the one or more power configuration parameters received at the controlling node from the repeater comprise a power headroom parameter associated with the repeater, a current transmit power parameter associated with the repeater, or a current gain setting value associated with the repeater;
• determine gain configuration information for the repeater based on the power headroom parameter associated with the repeater, the current transmit power parameter associated with the repeater, or the current gain setting value associated with the repeater;
• and
• transmit the gain configuration information from the controlling node to the repeater.
