  • Publication number: 20200145139
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol enables a sending station (STA) to communicate additional parity bits associated with an original transmission that included forward error correction (FEC) encoded codewords. Several techniques are described for a receiving STA to indicate which portions of the original transmission was not properly received. The receiving STA may store the original transmission for use with additional parity bits in a subsequent transmission. The sending STA may communicate the additional parity bits in a subsequent transmission to assist the receiving STA recover the data from the original transmission.

  • Patent number: 10588152
    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.

  • Patent number: 10523821
    Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.
