    摘要： This disclosure describes systems, methods, and devices related to antenna configuration parameters. A device may determine one or more antennas having one or more phases. The device may determine a first delay associated with a first antenna of the one or more antennas. The device may determine a second delay associated with a second antenna of the one or more antennas. The device may cause to send a frame to a first station device using the first antenna, wherein the frame comprises a first indication of the delay associated with the first antenna and a second indication of the delay associated with the second antenna.

    摘要： A station (STA) may operate as a first peer-to-peer (P2P) client (P2P1) for P2P operations with dual-stage triggering. The STA may decode a primary frame trigger frame (TF) from an access point (AP) operating as a coordinator. The primary TF may allocate resources in an initial portion of a time-duration allocation to the P2P1 for the P2P operations with one or more other peer stations, including a second P2P client (P2P2) and a third P2P client (P2P3). The primary TF may further allocate resources in a subsequent portion of the time-duration allocation to the P2P2 for the P2P operations. The STA may also encode a first secondary TF for transmission within the initial portion of the time-duration allocation. The first secondary TF may allocate specific resource units (RUs) to the one or more other peer stations. The STA may also decode a TB physical layer protocol data unit (TB PPDU) encoded in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format. The TB PPDU may be received concurrently within the initial portion of the time-duration allocation from the one or more other peer stations in accordance with an uplink OFDMA technique.

    摘要： Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.

    摘要： Technology for channel state information (CSI) feedback in a multiple-input multiple-output (MIMO) communication system is disclosed. A method comprises receiving, at a mobile device, a dynamic channel state information (CSI) feedback switch signal from a transmission station that identifies a selected CSI feedback state for the mobile device. A process for selecting a precoding matrix indicator (PMI) and a rank indicator is identified based on the CSI feedback switch signal as either a process configured for MU-MIMO reception or single-user (SU) MIMO reception of a downlink signal at the mobile device.
