  • Patent number: 10015174
    Abstract: Various aspects provide for receiving identity information from a station (STA) that identifies the STA as a sensor-type STA, determining whether communication attributes of the STA correlates with communication attributes expected for a sensor-type STA, and determining that the identity information received from the STA is false when the one or more communication attributes of the STA is uncorrelated with the one or more communication attributes expected for a sensor-type STA. Additional aspects provide for initiating one or more remedial actions upon determining that the identity information is false. The communication attributes may pertain to packet size, inter-arrival time, and/or inter-arrival time variance. The remedial actions may include blocking a future communication with the STA, communicating a warning message to the STA, and/or assigning the STA to a particular access window. Communications by the STA may comply with aspects of Institute of Electrical and Electronics Engineers (IEEE) 802.11ah.

  • Patent number: 9949293
    Abstract: Methods, systems, apparatuses, and devices are described for contention resolution techniques for medium access using a spatial dimension, a frequency dimension, or a combination of the both. A wireless station may determine that an access timer associated with backoff operations has expired. The wireless station may identify a domain index associated with the frequency domain, the spatial domain, or a combination. The wireless station may access the wireless medium according to the identified domain index. The wireless station may, prior to sending other transmissions, transmit a trigger frame including information associated with the resources of the wireless medium that are reserved for communications. Other wireless stations may share the medium and use the free resources.

  • Patent number: 9929847
    Abstract: Certain aspects of the present disclosure provide methods and apparatus for using a shortened block acknowledgement (BlockAck) frame capable of acknowledging fragments. Such a shortened BlockAck frame may include a bitmap field having a shorter length than that of a basic BlockAck frame in the IEEE 802.11 standard (i.e., <128 octets). One example method for wireless communications generally includes receiving a plurality of protocol data units (PDUs) (e.g., media access control (MAC) protocol data units (MPDUs)); determining whether each of the PDUs was successfully received and whether each of the PDUs is associated with a non-fragmented service data unit (SDU) (e.g., MAC service data unit (MSDU)) or a fragmented SDU; and outputting for transmission a shortened BlockAck frame comprising a bitmap field indicating a receive status for the non-fragmented and fragmented SDUs based on the determination.

  • Publication number: 20170064741
    Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

  • Publication number: 20170064713
    Abstract: A wireless device may utilize enhanced OBSS identification techniques to determine whether an interfering transmission is associated with an OBSS. In an example, a wireless device may receive a WLAN packet that includes a preamble and a data region. The wireless device may analyze the preamble to determine whether the WLAN packet is an OBSS packet. If the wireless device determines there is insufficient information in the preamble to identify the WLAN packet as an OBSS packet, the wireless device may decode a portion of the data region (e.g., a MAC header) to determine if the WLAN packet is an OBSS packet. Prior to declaring a successful decoding of the MAC header, the wireless device may confirm the MAC header has been received reliably. Additionally or alternatively, BSS identifiers may be included in the data region and used to determine if the WLAN packet is associated with an OBSS.
