Abstract: A method includes generating, at a second wireless device, a signal (SIG) unit to be transmitted to a first wireless device. The SIG unit includes a length field and an aggregation field. In response to determining to use aggregated transmission to the first wireless device, the method further includes setting the aggregation field to a first value and setting the length field to a number of symbols. In response to determining not to use the aggregated transmission to the first wireless device, the method further includes setting the aggregation field to a second value and setting the length field to a number of bytes.

Abstract: Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal is configured to be received over a bandwidth lower than or equal to 1.25 MHz. The packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones. The thirty-two tones correspond to frequency subcarriers within the bandwidth. The thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone. The apparatus includes a processor configured to evaluate the wireless signal. The processor includes a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.

Abstract: A method includes wirelessly communicating with one or more stations that are partitioned into one or more groups. The method also includes generating a message that identifies one or more time periods during which each station of a first group of the one or more groups is permitted to contend for a communication channel or restricted from contending for the communication channel. The method further includes transmitting the message.

Abstract: A method includes receiving, at a wireless device, a frame via a sub-1 gigahertz (GHz) wireless network. The frame includes a signal (SIG) unit including a length field and an aggregation field. The length field may be interpreted as a number of bytes or as a number of symbols based on a value of the aggregation field and based on whether the frame is associated with a 1 megahertz (MHz) bandwidth mode, based on whether the frame includes either a short format preamble or a long format preamble, or based on whether the frame is determined to be a single user (SU) frame or a multi user (MU) frame.
Abstract translation: 一种方法包括在无线设备处经由子1千兆赫（GHz）无线网络接收帧。 帧包括包括长度字段和聚合字段的信号（SIG）单元。 长度字段可以被解释为基于聚合字段的值的字节数或符号数，并且基于帧是否与1兆赫（MHz）带宽模式相关联，基于帧是否包括 短格式前导码或长格式前导码，或者基于帧被确定为单个用户（SU）帧还是多用户（MU）帧。
