  • Publication number: 20170245224
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a configuration message that includes overlapping basic service set (OBSS) coordination parameters. The OBSS coordination parameters may be used to select an OBSS preamble detection (PD) threshold or a transmission (TX) power, or both. For example, an OBSS coordination parameter may include an indication of an OBSS PD threshold or the TX power or a range of OBSS PD thresholds or TX powers. In some cases, the coordination parameter may include selection criteria that may be used to select the indicated OBSS PD threshold or TX power. Additionally or alternatively, a range of selection criteria may be used to select from a range of OBSS PD thresholds and TX powers. The wireless device may use the selected OBSS PD threshold or TX power to communicate with an AP or other devices.

  • Patent number: 9736855
    Abstract: Systems and methods for wireless communication are disclosed. In one aspect an access point transmits a message to a first device and a second device on a first channel, the message sufficient to inform the first device to camp on a first channel during a time slot and the message sufficient to inform the second device to camp on a second channel during the time slot. The access point further determines whether the first channel is busy during the time slot. If the first channel is determined to not be busy during the time slot, the access point communicates with the first device on the first channel during the time slot. If the first channel is determined to be busy during the time slot, the access point communicates with the second device on the second channel during the time slot.

  • Publication number: 20170135133
    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.
