1. A method performed by a multi-link device (MLD) wireless access point apparatus that serves at least a first basic service set (BSS) by a first access point and a second BSS by a second access point, the method comprising:
advertising, by the second access point, to one or more wireless stations (STAs) a first change sequence number for the first access point; and
responsive to a BSS parameter update corresponding to the first BSS and first access point:
generating a frame comprising a data element, wherein the data element includes
a second change sequence number corresponding to the first BSS and first access point and associated with the BSS parameter update; and
a flag to indicate whether data characterizing the BSS parameter update for the first access point is included in the frame; and
transmitting the frame by the second access point in the second BSS.
