1. A method, comprising:
receiving, by a wireless access point (AP) of a set of wireless APs, a first unsafe frequency report from a first client device, the first unsafe frequency report indicating that the first client device is experiencing interference on a first set of frequencies;
identifying, for the first client device, a set of safe frequencies based on interference indicated in the first unsafe frequency report; and
performing dynamic puncturing based on the first unsafe frequency report, comprising:
identifying, by a multi-AP coordinator, an allocation of wireless resources for the first client device during a first transmission opportunity based on the set of safe frequencies and a set of unsafe frequency reports for the set of wireless APs, wherein the allocation of wireless resources punctures one or more of the first set of frequencies; and
communicating with the first client device using the allocation of wireless resources.
