A method for wireless communications by an apparatus includes obtaining a configuration that indicates one or more parameters for power headroom reporting, wherein the one or more parameters include an indication to enable reporting of at least first information associated with full-duplex communications; and sending a first power headroom report that comprises the first information associated with full-duplex communications. ## Claims ### Claim 1 An apparatus configured for wireless communications, comprising: one or more memories; and one or more processors coupled to the one or more memories, the one or more processors being configured to cause the apparatus to: obtain a configuration that indicates one or more parameters for power headroom reporting, wherein the one or more parameters include an indication to enable reporting of at least first information associated with full-duplex communications; and send, via one or more first resources allocated for half-duplex communications, a first power headroom report that comprises the first information associated with full-duplex communications, wherein the first information is based on a first communication via one or more second resources allocated for full-duplex communications. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the indication includes a field that indicates to enable reporting of the first information associated with full-duplex communications and second information associated with half-duplex communications. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein: the one or more processors are configured to cause the apparatus to send, via one or more first resources allocated for half-duplex communications, a second power headroom report that includes second information associated with half-duplex communications, and the second information is based on a half-duplex communication via the one or more first resources. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the first communication includes a reference transmission. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein: the one or more processors are configured to cause the apparatus to send, via the one or more second resources allocated for full-duplex communications, a second power headroom report that includes second information, and the second information is based on a second communication via the one or more first resources allocated for half-duplex communications. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the second communication includes a reference transmission. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the one or more processors are configured to cause the apparatus to send capability information that indicates the apparatus supports reporting power headroom information associated with full-duplex communications. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the first information includes an indication of a power headroom value for the first communication and an indication of a maximum allowed transmit power for the first communication. ### Claim 9 An apparatus configured for wireless communications, comprising: one or more memories; and one or more processors coupled to the one or more memories, the one or more processors being configured to cause the apparatus to: send a configuration that indicates one or more parameters for power headroom reporting, wherein the one or more parameters include an indication that enables reporting of at least first information associated with full-duplex communications; and obtain, via one or more first resources allocated for half-duplex communications, a first power headroom report that comprises the first information associated with full-duplex communications, wherein the first information is based on a first communication via one or more second resources allocated for full-duplex communications. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the indication includes a field that indicates to enable reporting of the first information associated with full-duplex communications and second information associated with half-duplex communications. ### Claim 11 (depends on 9) The apparatus of claim 9, wherein: the one or more processors are configured to cause the apparatus to obtain, via one or more first resources allocated for half-duplex communications, a second power headroom report that includes second information associated with half-duplex communications, and the second information is based on a half-duplex communication via the one or more first resources. ### Claim 12 (depends on 9) The apparatus of claim 9, wherein the first communication includes a reference transmission. ### Claim 13 (depends on 9) The apparatus of claim 9, wherein: the one or more processors are configured to cause the apparatus to obtain, via the one or more second resources allocated for full-duplex communications, a second power headroom report that includes second information, and the second information is based on a second communication via the one or more first resources allocated for half-duplex communications. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the second communication includes a reference transmission. ### Claim 15 (depends on 9) The apparatus of claim 9, wherein the one or more processors are configured to cause the apparatus to obtain capability information that indicates a user equipment supports reporting power headroom information associated with full-duplex communications. ### Claim 16 A method for wireless communications by an apparatus comprising: obtaining a configuration that indicates one or more parameters for power headroom reporting, wherein the one or more parameters include an indication to enable reporting of at least first information associated with full-duplex communications; and sending, via one or more first resources allocated for half-duplex communications, a first power headroom report that comprises the first information associated with full-duplex communications, wherein the first information is based on a first communication via one or more second resources allocated for full-duplex communications.
