Abstract: Embodiments are provided for WLAN Orthogonal Frequency Division Multiple Access (OFDMA) design of subcarrier groups and corresponding frame format. An embodiment method includes grouping a plurality of subcarriers for OFDMA transmissions into a plurality of subcarrier groups in accordance with a pre-defined grouping structure for subcarriers. The method further includes allocating the subcarrier groups to a plurality of corresponding users, and signaling, to the users, a map of the subcarrier groups to the corresponding users. According to the pre-defined grouping structure, each one of the subcarrier groups includes a plurality of consecutive subcarriers, a plurality of non-consecutive subcarriers, or a combination of consecutive and non-consecutive subcarriers according to a deterministic structure. The map is signaled using an OFDMA PPDU comprising a legacy preamble portion configured to silence legacy users that do not use OFDMA communications, an OFDMA preamble portion indicating the map, and a data portion.

Abstract: Embodiments are provided to enable concurrent uplink transmissions from multiple Wi-Fi stations (STAs) to one or more access points (APs) using Interference Alignment (IA). In an embodiment, the STAs broadcast, to one or more APs, beamforming reports including channel estimation information for downlink. The one or more AP then performs channel estimation using the beamforming reports, and selects at least some of the STAs. The AP also computes beamforming information for IA of uplink transmissions between the selected STAs and sends, to the selected STAs, the beamforming information. The beamforming information is piggy-backed over downlink data packets to the selected STAs. Each selected STA then sends an uplink data frame concurrently with one or more other uplink data frames from one or more other selected STAs to the AP. The uplink data frames are configured for concurrent uplink transmissions according to the beamforming information for IA.

Abstract: Embodiments are provided herein for improving carrier aggregation for wireless networks. A plurality of bandwidth channels are assigned to a basic service set (BSS) for transmissions. Specifically, the bandwidth channels are divided into multiple channel segments corresponding to multiple primary or alternate primary channels. A channel segment possibly further includes one or more additional secondary channels. The locations of the primary or alternate primary channels that correspond to the channel segments of the BSS are then broadcasted in the network. When a station or AP receives this BSS information, it searches for an available primary or alternate primary channel of the BSS to begin transmission. Upon detecting an available primary channel or alternate primary channel that is not used for another transmission, the station or AP transmits data on the channel segment corresponding to the detected primary or alternate primary channel.

Abstract: The present disclosure provides methods and apparatus related to NDPA frame indication. An aspect of the disclosure provides a method. The method includes sending, to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a first field and a second field. The first field indicates presence of the second field, and the second field indicates a variant of the NDPA frame. The method further includes receiving, from the one or more STAs, a CSI feedback response based on the request. In some embodiments, the first field is one of a sounding dialog token field and indicates the presence of the second field via at least two bits. In some embodiments, the first field is a frame control field and indicates the second field via a 4-bit subtype subfield.

Abstract: A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialize the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.
