  • Publication number: 20200107318
    Abstract: Multiple trigger frames are generated at a first communication device to trigger an uplink orthogonal frequency multiple access (OFDMA) transmission by multiple second communication devices. The multiple trigger frames include a broadcast trigger frame that includes information to indicate transmission parameters for a first subset of the second communication devices, and one or more unicast trigger frames, each of the one or more unicast trigger frame including information to indicate transmission parameters for a particular second communication device in a second subset of the second communication devices. The broadcast trigger frame is transmitted, in a first frequency portion of a downlink OFDMA transmission, to the first subset of the second communication devices, and respective unicast trigger frames are transmitted, in respective second frequency portions of the downlink OFDMA transmission, to the second subset of the second communication devices.

  • Patent number: 10595338
    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.

  • Patent number: 10581580
    Abstract: A first communication device receives an aggregate medium access control data unit (MAC) protocol data unit (A-MPDU) that aggregates multiple MAC protocol data units from a second communication device. The first communication device generates an acknowledgment data unit that includes a length indication that indicates a length of an acknowledgement field and the acknowledgment field of the indicated length. The length of the acknowledgement field is selected from a subset of predetermined lengths, among a set predetermined lengths, that includes multiple predetermined lengths that do not exceed a maximum number of MAC protocol data units that can be included in the A-MPDU. The maximum number of MAC protocol data units is limited by a buffer size negotiated in an acknowledgement setup procedure previously conducted between the first communication device and the second communication device. The first communication device transmits the acknowledgment data unit to the second communication device.

  • Patent number: 10567996
    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.

  • Publication number: 20200037357
    Abstract: A communication device generates a first data unit that spans a first bandwidth, and transmits the first data unit during a transmit opportunity (TXOP) to at least one other communication device. The communication device subsequently determines, based on respective values of TXOP duration fields included in respective physical layer (PHY) preambles of one or more data units previously transmitted during the TXOP, whether a second bandwidth of a second data unit to be transmitted by the communication device during the TXOP can be greater than the first bandwidth of the first data unit. In response to determining that the second bandwidth of the second data unit can be greater than the first bandwidth of the first data unit, the communication device generates the second data unit to span the second bandwidth greater than the first bandwidth, and transmits the second data unit during the TXOP.
