Abstract: A communication device determines, in connection with a prior uplink multi-user (UL MU) communication in which the communication device participated, whether the communication device is to use one or more first channel access parameters, or one or more second channel access parameters for accessing a communication medium for a single user (SU) transmission by the communication device, where using the one or more first channel access parameters is associated with a greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters. Depending on the determination made, the communication device uses the one or more first channel access parameters, or the one or more second channel access parameters to attempt to access the communication medium. In response to accessing the communication medium, the communication device transmits the SU transmission via the communication medium.

Abstract: Embodiments described herein provide a method for fragmenting and reassembling data frames on a medium access control (MAC) layer in a wireless local area network. A datagram is received from an application running on a first network device, for transmission over a wireless communication link in the wireless local area network. A negotiation request is initiated with a second network device for determining whether both the first network device and the second network device have enhanced directional multi-gigabit capability (EDMG) for data segmentation and reassembly. When both devices have EDMG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.

Abstract: Aspects of the disclosure are directed to an apparatus having a multi-link device (MLD) including processing circuitry to communicate signals with one of a plurality of remote devices over multiple communications link. The MLD and the one of the remote devices operate in first and second communication-specific configurations as follows. A physical layer convergence procedure protocol data unit (PPDU) is transmitted in one of the links while a PPDU is communicated in another one of the links under a first configuration. A PPDU is communicated in a first one of the respective communications links with an ending time set based on a PPDU communicated in a second one of the respective communications links in a second configuration. Such approaches may be carried out based on capabilities relating to simultaneous transmission and reception of MLDs that are communicating.
