  • Patent number: 9596648
    Abstract: A beacon frame corresponding to a unified beacon format is generated. Generating the beacon frame comprises generating a first portion of the beacon frame, wherein the first portion has the same format whether (i) it is determined to transmit a short beacon frame or, (ii) it is determined to transmit a full beacon frame. A second portion of the beacon frame is generated. The second portion corresponds to a first subformat when it is determined to transmit the short beacon frame, and the second portion corresponds to a first subformat when it is determined to transmit the full beacon frame. The first subformat is different than the second subformat. An indication of whether the beacon frame corresponds to the first subformat or the second subformat is included (i) in the beacon frame or (ii) in a physical layer (PHY) header associated with the beacon frame.

  • Publication number: 20170070418
    Abstract: Disclosed herein are system, method, and computer program product embodiments for selectively decoding a multicast subframe in a multi-user frame for a wireless communications protocol. Embodiments include transmitting a request frame including a multicast group address for a multicast group to an access point (AP). The AP can determine a multicast identifier for the multicast group based on the multicast group address in the request frame. The AP can also transmit a response frame including the determined multicast identifier to a station (STA). The STA can receive a multi-user frame containing a multicast subframe from the AP. The STA can determine whether the multicast subframe is destined for the STA based on the determined multicast identifier and a multicast identifier stored in a preamble of the multi-user frame. The STA can determine whether to decode the multicast subframe based on the determination of whether the multicast subframe is destined for the STA.

  • Patent number: 9591490
    Abstract: A method for generating signals to be transmitted within a BSS channel, where a set of component channels is collectively coextensive with the BSS channel, includes determining that a first duplicate, in frequency, of a low bandwidth mode data unit will be located at an edge of the BSS channel. Each duplicate includes OFDM tones and has a bandwidth less than the narrowest channel of the component channels. The OFDM tones in each duplicate include one or more data tones, one or more pilot tones, and one or more guard tones. The method also includes generating a transmission signal comprising the duplicates, at least in part by scaling down at least one data tone, and/or zeroing out at least one data tone, of the first duplicate in response to determining that the first duplicate will be located at an edge of the BSS channel.

  • Publication number: 20170026280
    Abstract: A packet transmission method, packet transmission apparatus, and an interconnect interface are presented, where the method includes determining, by a sending node, whether an unrecoverable failure occurs in an active link, and if an unrecoverable failure occurs in the active link, selecting, from multiple communication links, at least one standby link except the active link to send a packet to a receiving node, so that the receiving node sends the packet to a receive end of the active link. In the method, for two nodes in an interconnect system that communicate with each other using multiple Links, when it is determined that an unrecoverable failure occurs in some of the Links, packets in retransmission buffers of transmit ends of the links in which the failure is unrecoverable are sent to a standby link.
