Access point (AP) controlled uplink RTS/CTS configuration and disablement

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 mayidentify 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.

Problems solved by technology

[0006] However, traditional systems rely on rigid RTS / CTS protocol procedures without considering changing conditions in the wireless network, which may cause other problems that adversely affect the overall network performance

In one example, the use of conventional RTS / CTS protocols can lead to exposed terminal issues, where a wireless node located nearby but associated with another AP (e.g., an overlapping basic service set (OBSS) node) can overhear the AP. exchange, and thus force backoff and stop transmission for a specific period of time in RTS
