Abstract
Certain aspects of the present disclosure generally relate to using bloom filter hash functions for service hint information in advertisements such as beacons and probe responses. Certain aspects provide an apparatus for wireless communications, such as an access point (AP). The apparatus generally includes a processing system configured to generate a plurality of bitmaps that indicate one or more services known by the apparatus, each bitmap being generated by applying a different set of one or more cyclic redundancy check (CRC) based hash functions to one or more service identifications (IDs) of each service, and to generate one or more frames, each frame including one of the plurality of bitmaps and an indication of the set of one or more CRC based hash functions used to generate the bitmap included in the frame, and an interface configured to output the one or more frames for transmission.
