Abstract: The present disclosure provides a wireless communication device, method, system and computer program product for supporting BA mechanism. The wireless communication method includes: receiving, from a peer wireless communication device, a support indication for sparse block acknowledgment (BA) bitmap condensation for a plurality of data frames to be communicated between the wireless communication device and the peer wireless communication device in a BA session; and transmitting, to the peer wireless communication device, a condensed BA bitmap for the BA session based on the support indication.

Abstract: The present disclosure provides a method and an access point multi-link device (AP MLD). An AP MLD according to the embodiment of the present disclosure includes a plurality of affiliated access points (APs), wherein in a multi-link scheduling power saving mode, each affiliated AP of the plurality of affiliated APs is in an awake state at a first scheduling information frame to transmit scheduling information on its link, wherein the scheduling information indicates one or more service periods (SPs) after the first scheduling information frame for the plurality of affiliated APs, wherein links of the plurality of affiliated APs are in the non-simultaneous transmit and receive (NSTR) operation mode, in each SP of the one or more SPs, only one affiliated AP in the plurality of affiliated APs is in an awake state after the first scheduling information frame.

Abstract: The present disclosure provides a method, an AP and a non-transitory computer readable medium. A method for communication performed by the AP, the method includes: determining whether to perform a communication optimization process based on the communication performance of the AP; in response to determining to perform the communication optimization process, dividing AP antennas of the AP into a first number of AP antenna groups based on a first grouping standard set, wherein the first number is less than a the number of the AP antennas of the AP; and selecting target AP antennas for communication, wherein no more than one target AP antenna is selected in each AP antenna group as target AP antennas, and using the target AP antennas for communication.
