Abstract: A first AP establishes TWT-based multi-AP coordination with a second AP in multi-AP coordination set for a TWT schedule or a TWT agreement identified by a first TWT parameter set. When the first AP intends to make any changes or updates to parameters to the TWT schedule or the TWT agreement, the first AP notifies the second AP about the impending changes before the first AP makes the changes to the TWT parameters.

Abstract: Methods and apparatuses for facilitating multi-access point (MAP) target wake time (TWT) coordination (or TWT-based MAP coordination) operations in a wireless local area network (WLAN). A method performed by a first access point (AP) comprises determining to participate in TWT coordination with a second AP operating in a second basic service set (BSS), wherein the first AP operates in a first BSS and wherein the first AP and the second AP are members of a coordinating AP set for multi-AP (MAP) TWT coordination. The method further comprises transmitting, in the first BSS, a message indicating a first broadcast TWT (B-TWT) schedule that corresponds to a second B-TWT schedule established in the second BSS.

Abstract: Methods and apparatuses for facilitating selection between operating modes of MLDs. A non-AP MLD comprises a processor and STAs having first and second links operating in the 5 and 2.4 GHz bands, respectively, with APs of an AP MLD. The processor determines: based on traffic latency/throughput requirements, to operate in STR mode using both links, or, based on power saving requirements, to operate in a single link mode using the second link, or, based on the power savings requirements having a higher priority than the latency/throughput requirements, to operate in EMLSR mode using both links or in the single link mode using the first link. If the power savings and latency/throughput requirements are balanced, the processor determines: in a high contention environment, to operate in EMLSR mode using both links or, in a low contention environment, to operate in STR mode using both links.

Abstract: A first access point (AP) device receives information related to a target wake time (TWT) schedule established in a second basic service set (BSS). The second BSS is established by the second AP device. The first AP device shall ensure that a transmission opportunity (TXOP) established in a first BSS ends before a start time of a TWT service period of the TWT schedule established in the second BSS. The first BSS is established by the first AP device.

Abstract: Methods and apparatuses for joint transmission operations in Wi-Fi networks. A method of wireless communication performed by a first access point (AP) includes determining that the first AP and other APs of a plurality of APs want to perform joint transmission (JTX) with stations (STAs) associated with the first AP and the other APs. The method also includes initiating a JTX procedure including forming a logical AP multi-link device (MLD) or a virtual AP MLD with the other APs to perform JTX.

Abstract: Methods and apparatuses for handling TDLS latency issues in non-collocated APs. A method of wireless communication performed by a first STA comprises: initiating a TDLS procedure between the first STA and a second STA via an AP of a plurality of APs that are associated with the first STA and the second STA, wherein: a first subset of the plurality of APs form a logical AP multi-link device (MLD), and the second STA is associated with either the first AP or a second AP of the plurality of APs; determining, based on the TDLS procedure, whether the plurality of APs are non-collocated; and adjusting a response time for receiving data from the plurality of APs or from the second STA based on the determination of whether the plurality of APs are non-collocated.
