1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a first non-access point (non-AP) station (STA), a Basic Multi-Link (ML) element from a first AP; and
decoding, by the first non-AP STA, the basic ML element,
wherein the first AP operating on a first link and a second AP operating on a second link are affiliated with an AP multi-link device (MLD),
wherein the first non-AP STA operating on the first link and a second non-AP STA operating on the second link affiliated with a non-AP MLD,
wherein the basic ML element includes a Per-STA Profile subelement for the second AP,
wherein the Per-STA Profile subelement for the second AP includes a first basic service set (BSS) Parameters Change Count present subfield,
wherein based on the first BSS Parameters Change Count present subfield set to 1, the Per-STA Profile subelement for the second AP includes the first BSS Parameters Change Count subfield, and
wherein the first BSS Parameters Change Count subfield includes the most recent BSS parameters change count of the second AP.
