  • Publication number: 20170181190
    Abstract: A client station (STA), when operating in a wireless network, receives data sent by an access point (AP) on a first channel comprising at least one subchannel. During reception of the data on the first channel, the STA monitors channel availability of an additional set of one or more subchannels. In response to a detected availability of at least one newly-available subchannel, the STA sends at least one notification to the AP identifying STA-side availability of the newly-available subchannel(s). The STA subsequently receives data from the AP on the newly-available subchannel(s), which is sent in response to the at least one notification. The AP, when communicating data to the STA, receives the at least one notification from the STA and, in response thereto, initiates data transmission on one or more of the newly-available channel(s).

  • Patent number: 9680627
    Abstract: Embodiments of a system and method for selecting a duplex mode for a service operating in a Wireless Network are generally described herein. In some embodiments, a mobile device may receive one or more traffic packets related to an establishment or a re-establishment of a service at the mobile device, and may select a duplex mode for the service. In some embodiments, the mobile device may be an IEEE 802.11 Station (STA). The mobile device may be configured to select full-duplex as the duplex mode when a delay requirement associated with the service is less than a predetermined delay threshold and when a calibration overhead associated with the mobile device or the service is less than a predetermined calibration overhead threshold.

  • Publication number: 20170156160
    Abstract: A Spatial Multiple Access Uplink for Wireless LANs is generally described herein. A novel FD-MiMAC, protocol leverages full duplex functionality at the Access Point, can be incrementally deployed with current 802.11 Access Point and client devices, can be easily implemented by client devices in a distributed and contention based manner, and pairs users in uplink MU-MIMO to enhance system performance. A method for spatial multiple access uplink in a wireless local area network comprises announcing, by an Access Point (AP), its available remaining antenna capability, receiving, by the AP, a packet header frame transmitted by a winning client uplink contender, allocating, by the AP, uplink resources for the winning client uplink contender and immediately announcing its remaining antenna capability, and transmitting, by the AP, at the end of a winning client's transmission burst, an Acknowledge-to-All frame, whereby other clients may simultaneously restart contention for transmission of next frames.

  • Patent number: 9660793
    Abstract: Techniques for presenting communication between two or more stations in a WLAN environment are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way for fast rate adaptation based on full duplex functionality, increasing link and network throughput. The present disclosure includes a method that provides a fast rate adaptation by leveraging full duplex in order to get immediate channel quality feedback.

  • Publication number: 20170141867
    Abstract: Embodiments of wireless communication devices (WCDs) and methods for cancelling signal interference in the WCDs are generally described herein. Some of these embodiments describe a WCD that includes a receiver to generate a received signal, which includes at least a first signal transmitted to the WCD by a network station that operates in a full-duplex mode while the WCD operates in a half-duplex mode. The WCD also includes a module to generate an interference cancellation signal for the received signal based on interference information obtained from at least the received signal. The interference information is associated with a second signal transmitted to the network station by an additional device. The first signal is transmitted while the second signal is transmitted. The first and second signals include the same radio-frequency (RF) carrier.

  • Patent number: 9572068
    Abstract: This disclosure describes systems, methods, and computer-readable media related to employing rate adaptation in full-duplex communication. A first computing device may establish with a second computing device a full-duplex communication channel having a forward data transmission direction and a reverse data transmission direction. The first computing device may transmit to the second computing device a first data portion in the forward data transmission direction of the full-duplex communication channel at a default data transmission rate. The first computing device may receive a second data portion in the reverse direction of the full-duplex communication channel containing a forward channel quality information (CQI) associated with the forward data transmission direction. The first computing device may transmit a third data portion at a first data transmission rate, wherein the first data transmission rate is based at least in part on the forward CQI contained in the second data portion.

  • Patent number: 9491776
    Abstract: Certain embodiments herein relate to scheduling interference between wireless devices in a manner that reduced interference associated with full duplex communication. Signal strength and interference information associated with communication between wireless devices may be collected and forwarded to a processing device, such as a central controller. The central controller may utilize such information to generate a conflict graph that depicts interference relationships between the wireless devices. Using the conflict graph, the central controller may determine whether requested communications may be scheduled along with concurrently scheduled communications without resulting in interference affecting the communications. In one embodiment, a requested communication may be scheduled with other concurrently scheduled communications if the aggregated throughput is increased with the addition of the requested communication.
