1. An access point configured with a plurality of resource units (RUs), each RU configured to use a frequency range that differs from frequency ranges used by the other RUs, the access point comprising one or more processors operable to:
determine a pattern of recurring signal performance over time, wherein, for each RU of the plurality of RUs, the pattern indicates the recurring signal performance with respect to a station when located in a given physical location; and
allocate one or more of the RUs for communicating with the station, wherein the pattern is used for avoiding allocation of any of the RUs for which the station is predicted to experience strong multipath fading or other destructive interference;
wherein to determine the pattern, the access point is operable to perform a procedure for each RU in a subset selected from the plurality of RUs, the procedure comprising:
sending a signal to the station via the respective RU; and
determining the signal performance associated with the respective RU based on whether a response to the signal is received from the station.
