1. An apparatus for wireless communication at a first device that supports full-duplex communications in a wireless network, comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the first device to:
transmit a first message over a first sidelink communication link to a second device, the first message transmitted via a first directional beam;
receive, concurrently with transmission of the first message, a second message over a second sidelink communication link from a third device, the second message received via a second directional beam different from the first directional beam; and
broadcast a third message comprising an indication of a set of parameters that indicates an interference level at the first device satisfies a threshold, the set of parameters based at least in part on the second message and the first message.
 
15. An apparatus for wireless communication at a first device, comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the first device to:
receive, from a second device in a wireless network, a first message comprising a first set of parameters that indicates an interference level at a first location of the second device satisfies a first threshold and a presence or an absence of one or more objects that cause the interference level at the first location of the second device;
receive, from a third device in the wireless network, a second message comprising a second set of parameters that indicates an interference level at a second location of the third device that is different from the first location satisfies a second threshold and a presence or an absence of one or more objects that cause the interference level at the second location of the third device, wherein the first set of parameters and the second set of parameters each comprises location information, directional beam information, antenna array information, velocity information, or any combination thereof; and
transmit a third message comprising an indication of a communications parameter based at least in part on the first location and the second location, wherein the communications parameter indicates at least one or more beam directions for communication at a third location, and wherein the third location is different from the second location and the first location.
 
22. An apparatus for wireless communication at a first device that supports full-duplex communications in a wireless network, comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the first device to:
receive, from a second device, a first message comprising a first set of parameters that indicates an interference level at a first location of the second device satisfies a first threshold and a presence or an absence of one or more objects that cause the interference level at the first location of the second device;
receive, from a third device, a second message comprising a second set of parameters that indicates an interference level at a second location of the third device that is different from the first location satisfies a second threshold and a presence or an absence of one or more objects that cause the interference level at the second location of the third device, wherein the first set of parameters and the second set of parameters each comprises location information, directional beam information, antenna array information, velocity information, or any combination thereof; and
communicate with a fourth device over a sidelink communication link via a communications parameter that is based at least in part on the first set of parameters and the second set of parameters.
 
25. An apparatus for wireless communication at a first device that supports full-duplex communications in a wireless network, comprising:
one or more memories; and
one or more processors coupled with the one or more memories and configured to cause the first device to:
receive, from a second device, a message comprising a communications parameter that indicates an interference level at a first location of the first device satisfies a threshold and a presence or an absence of one or more objects that cause the interference level at the first location of the first device, wherein the communications parameter comprises location information, directional beam information, antenna array information, velocity information, or any combination thereof; and
communicate with a third device over a sidelink communication link via a directional beam in accordance with one or more beam directions, wherein the one or more beam directions are based at least in part on the communications parameter and a second location of the third device.
