Abstract: Techniques for efficient network probing are provided. Coherence data is received from a plurality of access points (APs), where the coherence data indicates, for each respective AP of the plurality of APs, coherence bandwidth for a plurality of subcarriers. A mapping is generated indicating, for each of the plurality of APs, sets of subcarriers that can be interchangeably sounded. Two or more APs of the plurality of APs that can jointly sound a first subcarrier of the plurality of subcarriers are then identified based on the mapping, and the first subcarrier is allocated to the identified two or more APs for future sounding.

Abstract: Techniques for triggering multiple basic service sets (BSSs) to share resources for a coordinated transmission are described. One technique includes determining a first amount of data available to send in a first BSS and determining a second amount of data available to send in a second BSS. The first BSS and the second BSS form an overlapping BSS. An amount of resources in the first BSS that is available to share with the second BSS for a coordinated transmission from the first BSS and the second BSS is determined based on the first amount of data and the second amount of data. A frame that includes an indication of the amount of resources is generated and transmitted to at least one of the first BSS and the second BSS.
