Abstract: Embodiments are disclosed for address changing schemes in a wireless communications system. Some embodiments include an access point (AP) that can establish two or more address profiles with a station (STA), establish a schedule for switching from a first address profile to a second address profile, where the first and second address profiles are of the two or more address profiles, and transmit a first data transmission using the first address profile. Some embodiments include switching from the first address profile to the second address profile based on the schedule, and transmitting a second data transmission using the second address profile. The schedule can be based on a randomized time synchronization function (TSF). The AP can establish a joint algorithm with the STA, and use the joint algorithm determine the first and the second address profiles as well as transition times for the schedule.

Abstract: Embodiments are disclosed for triggered multi-link (ML) access coordination. A station (STA) ML device (MLD) can establish a preferred triggering link (PTL) with an access point (AP) MLD where the PTL is the preferred link for receiving triggering frames. The STA MLD can transmit uplink (UL) frames via the PTL in response to a trigger frame. Subsequently, the STA MLD can determine that the PTL is busy, and transmit enhanced distributed channel access (EDCA) UL frames on a non-PTL link. In a power save mode, the STA MLD can use the PTL to exchange UL and downlink (DL) frames. Multiple PTLs can be established supporting concurrent trigger frames, and different ranges of traffic IDs (TIDs) can be used for each PTL. The STA MLD can utilize AP MLD link pair information to receive a DL retransmission corresponding to one TID via both links of the AP MLD link pair.

Abstract: Some aspects include apparatuses and methods for implementing a target wake time (TWT) scheme (or technique) for multi-link wireless communication networks. For example, a multi-link device (MILD) includes a first station (STA) associated with a first link of a wireless network and configured to communicate with a second MLD over the first link using a multi-link target wake time (TWT) process. The MLD also includes a second STA associated with a second link of the wireless network and configured to communicate with the second MLD over the second link using the multi-link TWT process. The MLD further includes one or more processors communicatively coupled to the first and second STAs and configured to control the operations of the first and second STAs to perform the multi-link TWT process.

Abstract: Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.
