1. An apparatus, comprising:
a Radio Frequency (RF) interface; and
processor circuitry coupled with the RF interface and configured to:
determine Buffered Unit (BU) information, which indicates presence or absence of BUs for a set of non-Access Point (AP) Multi-link Devices (MLDs) on an AP MLD;
encapsulate the BU information for the set of non-AP MLDs in a Multilink (ML) Traffic Indication Map (TIM) information element; and
provide the ML TIM information element to the RF interface for broadcasting, wherein
the ML TIM information element comprises a series of TIM segments and each TIM segment contains the BU information, which indicates the presence or absence of BUs for a subset of non-AP MLDs on a corresponding AP within the AP MLD.
