Claim of US Patent No. 10,972,993

1. An apparatus comprising:memory; and
an integrated circuit coupled with the memory to be used in a station (STA), the integrated circuit coupled with the memory to cause the station to:
set an initial transmission window (TW) value for a TW size, the TW size to indicate a number of discovery windows;
determine a selection number that is an integer between a minimum TW size and the TW size, the selection number to indicate a discovery window (DW) of the number of discovery windows between the minimum TW size and the TW size, to allow the apparatus to transmit, on average, one discovery frame every TW size DWs;
transmit a discovery frame within the DW; and
adjust the TW size based on a transmission start time of the discovery frame, to limit transmissions to a subset of the DWs based on a number of devices that compete for access, the TW size to indicate, on average, more than one DW every TW size DWs.
