  • Patent number: 10111185
    Abstract: A communication device receives a signal during a backoff period of a backoff procedure, wherein the communication device is part of a first communication network. In response to determining that i) the signal is valid, ii) the signal is from another communication network, and iii) the power level of the signal does not meet a threshold that is higher than a default threshold, the communication device continues a count of a backoff timer during reception of the signal. In connection with comparing the power level of the signal to the threshold higher than the default threshold, the communication device sets a transmit power level to a reduced power level that is lower than a default power level. The communication device transmits at a transmit power level that is less than or equal to the reduced transmit power level in response to the backoff timer expiring.

  • Patent number: 10079709
    Abstract: In a method for generating a data unit, it is determined whether the data unit is to be transmitted using single carrier (SC) modulation or orthogonal frequency division (OFDM) modulation. When it is determined that the data unit is to be transmitted using SC modulation, a header field of the data unit is generated using a first technique to indicate that the data unit conforms to a first protocol and/or whether the data unit conforms to a first PHY mode or a second PHY mode of the first protocol. When it is determined that the data unit is to be transmitted using OFDM modulation, the header field is generated using a second technique to indicate that the data unit conforms to the first protocol and/or whether the data unit conforms to the first PHY mode or the second PHY mode of the first protocol.

  • Publication number: 20180262951
    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 (EMDG) for data segmentation and reassembly. When both devices have EMDG 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.
