Classification: CPC H | IPC H

Claim 19:
20. An apparatus for wireless communications at a second wireless device, comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory, wherein the instructions are executable by the processor to:
receive, from a first wireless device different from the second wireless device, a first wireless transmission over a channel of a radio frequency spectrum band, the first wireless transmission comprising a data portion and a preamble that indicates resources for indicating interference corresponding to the first wireless transmission and a first physical cell identifier (PCI) associated with the first wireless device;
detect interference of the first wireless transmission with a second wireless transmission, the second wireless transmission corresponding to communications between a third wireless device and a fourth wireless device, the fourth wireless device being different from the second wireless device and the third wireless device;
transmit, to the first wireless device and via the resources indicated by the preamble, an indication of interference indicating that the first wireless transmission from the first wireless device interfered with the second wireless transmission between the third wireless device and the fourth wireless device, wherein the indication of interference includes a preamble comprising a second PCI associated the third wireless device;
enable an interference avoidance mechanism at the first wireless device based at least in part on the indication of interference;
map a set of available resources to the first PCI associated with the first wireless device and the second PCI associated with the third wireless device; and
implement the interference avoidance mechanism based at least in part on mapping.
