    Abstract: A resource indication method in a wireless local area network is provided, where the method includes generating, by an access point, a data frame that includes a preamble, where the preamble includes a signaling indication part B (SIG-B), the SIG-B includes a common part and a user part following the common part. The common part is used to indicate a quantity of scheduled stations, identification information of the scheduled station, and a location of communication resource information of the scheduled station in the user part, the user part is used to indicate the communication resource information of the scheduled station, and the communication resource information includes resource indication information, MCS information of a data part, spatial flow quantity information, or power control information; and sending the data frame.

    Abstract: An embodiment method includes receiving, by an access point (AP), a first authentication request from a station (STA) that requests authentication of the STA, transmitting, by the AP, a second authentication request to a server that requests including extensible authentication protocol (EAP) authentication signaling to verify mutual possession of a shared key between the STA and the server, and receiving, by the AP, a first authentication response from the server in response to the second authentication request. The first authentication response includes an indication that authentication of the STA was successful. The method further includes transmitting, by the AP, a second authentication response to the STA, and receiving, by the AP, an association request that includes a message integrity code (MIC) from the STA.

    Abstract: Channel estimation performance may be improved by including more long training fields (LTFs) in a frame than Institute of Electrical and Electronic Engineers (IEEE) technical standard (TS) 802.11ac requires for the number of space-time streams. This may be particularly advantageous in orthogonal frequency division multiple access (OFDMA) networks, as it may allow the LTF sections of frames carrying different numbers of space-time streams to be aligned in the time domain.

    Abstract translation: 通过在一个帧中包含比电气和电子工程师协会（IEEE）技术标准（TS）更长的训练场（LTF）可以提高信道估计性能，802.11ac需要空时数量。 这在正交频分多址（OFDMA）网络中可能是特别有利的，因为它可以允许携带不同数量的时空流的帧的LTF部分在时域中对准。

    Abstract: An orthogonal frequency division multiple access (OFDMA) frame includes a 256 tone payload. The 256 tone payload may consist of either 234 data tones when the payload is carried in a downlink transmission. The 256 tone payload may consist of 216 data tones when the payload is carried in an uplink transmission. In addition, the OFDMA frame may include one or more resource units (RUs). Each of the one or more RUs may consist of either an integer multiple of 26 data tones or an integer multiple of 24 data tones and 2 pilot tones. Another embodiment OFDMA frame comprises a symbol-based RU (SRU) that may include an integer multiple of 2 pilots tones and either an integer multiple of 24 data tones or an integer multiple of 26 data tones.

    Abstract translation: 正交频分多址（OFDMA）帧包括256个色调有效载荷。 当有载荷在下行链路传输中携带时，256个音调有效负载可以由234个数据音调组成。 当上行链路传输中携带有效载荷时，256个音调有效负载可以由216个数据音调组成。 此外，OFDMA帧可以包括一个或多个资源单元（RU）。 一个或多个RU中的每一个可以由26个数据音调的整数倍或24个数据音调和2个导频音的整数倍组成。 OFDMA帧的另一实施例包括基于符号的RU（SRU），其可以包括2个导频音调的整数倍，以及24个数据音调的整数倍或26个数据音调的整数倍。
