Abstract: A wireless first device may receive a packet from another device from an overlapping basic service set (OBSS). A received power of the packet may be greater than a threshold for transmitting during the time of the packet. If the first device reduces its transmit power, the first device may increase the threshold. If the received power is less than the increased threshold, the first device may count down a backoff count during a transmission time or transmission opportunity of the packet. In some cases, after the transmission time or transmission opportunity, the first device may increase its transmission power. In some cases, the condition for counting down a backoff count may also include initiating or finishing the transmission during the transmission time or the transmission opportunity of the packet, or transmitting at the reduced power.

Abstract: Methods, systems, and devices for wireless communication are described. The described techniques may increase throughput of a wireless network, improve utilization of available channels, or provide other benefits. For example, the ability for a single traffic flow to span across different channels may increase the capacity of the network, may reduce communication latency, etc. In accordance with aspects of the present disclosure, a wireless device supporting multi-link communication may identify an anchor link and one or more supplementary links. For example, the anchor link may provide reliable communications while the supplementary links may provide increased throughput relative to the anchor link As an example, the anchor link may be dedicated for use to communicate management or control information, as well as data, while the supplementary links in the multi-link session may be used to communicate data according to the control and management information transmitted on the anchor link.
