  • Patent number: 10523404
    Abstract: Methods and apparatuses for asymmetric full duplex (FD) communications. Information about an uplink (UL) transmission opportunity (TXOP), including an indication of the TXOP, is sent by an access point (AP). The AP sends a downlink (DL) transmission to a receiving station. During the TXOP, an UL transmission is received from a transmitting station. The UL transmission at least partially overlaps in time with the DL transmission. Acknowledgement of the UL transmission is sent to the transmitting station, and acknowledgement of the DL transmission is received from the receiving station, at a synchronized time.

  • Publication number: 20190387525
    Abstract: Embodiments are provided for implementing a control function in a Wireless Local Area Network (WLAN) for allocation of resources to multiple stations (STAs) to enable Orthogonal Frequency Division Multiple Access (OFDMA) communications. An embodiment method includes determining a plurality of transmission resources for OFDMA communications of a plurality of STAs in the WLAN. The determination includes allocating a plurality of subcarriers to the STAs. The method further includes signaling the determined transmission resources to the STAs. The signaling of the transmission resources is piggybacked on at least one of data and management frames, such as in a sub-header of a MAC frame, or is an explicit signaling, such as in one or more dedicated fields of a traffic specification information element. The transmission resources for OFDMA communications allow simultaneous transmissions of the STAs in the WLAN.

  • Publication number: 20190334566
    Abstract: An OFDMA subframe carrying different data fields in different time segments may include a separate short training field (STF), and a separate set of long training fields (LTFs), for each of the data fields to accommodate time-reuse scheduling. Communicating a separate STF for each data field may allow receivers to re-adjust automatic gain control (AGC) when the data fields carry different numbers of space-time-streams. Likewise, communicating separate sets of LTFs for each data field may allow different beamforming parameters to be applied to different data fields.

  • Publication number: 20190230524
    Abstract: Embodiments are provided for enabling a coordinated beamforming (CB) mechanism in WLAN scenarios. In an embodiment, an AP sends a Feedback Request (FBR) frame to each one of the STAs in the OBSSs. The OBSSs comprise the STAs and a plurality of APs including the AP. The AP then receives a feedback frame from each STA of the STAs that participate in the CB transmission. The feedback frame includes channel state information (CSI) of the STA. The CSI enables the sending AP of performing CB on downlink. In an embodiment, the AP receives an initiate CB frame from a second AP initiating a CB transmission, and then sends an ACK frame to the second AP before sending the FBR frame to each one of the STAs. The AP starts the CB transmission with each one of the other APs that participate in the CB transmission.
