1. A method for use in a station (STA), the method comprising:
receiving a first null data packet announcement (NDPA) frame from a first access point (AP) and a second NDPA frame from a second AP, wherein the first AP is a primary AP that the STA is not associated with and the second AP is a secondary AP that the STA is associated with;
receiving, subsequent to the first NDPA frame, from the first AP, a first NDP frame used to select a first sector from among a plurality of sectorized transmissions from the first AP;
receiving, subsequent to the second NDPA frame, from the second AP, a second NDP frame used to select a second sector from among a plurality of sectorized transmissions from the second AP;
receiving, from the first AP, a sectorization confirmation signal indicating the first sector to be used by the first AP; and
transmitting, subsequent to the sectorization confirmation signal, a feedback frame that includes a sector identity corresponding to the second sector that is determined based on the first sector.
