Abstract: Methods, systems, and devices are described for enhanced network utilization between an access point and a number of wireless stations. A station (STA), following a transmit opportunity (TXOP), may determine a utilization of the TXOP. Based on the determination, the STA may adjust a delay time for a subsequent transmission. The adjustment of the delay time may include increasing an initial contention window (CW), increasing a backoff value, and/or increasing a number of backoffs for TXOPs following an underutilized TXOP. The increased delay time may result in, on average, increased backoff times in such situations. The delay time may be reduced to a minimum delay time following a certain number of TXOPs that more fully utilize the TXOP. Utilization of the TXOP may be determined based on an amount of time used for the TXOP relative to a TXOP limit that may be set by an access point.

Abstract translation: 描述了用于在接入点和多个无线站之间增强网络利用的方法，系统和设备。 在发送机会（TXOP）之后的站（STA）可以确定TXOP的利用。 基于该确定，STA可以调整后续传输的延迟时间。 延迟时间的调整可以包括在未充分利用的TXOP之后增加初始竞争窗口（CW），增加退避值和/或增加TXOP的退避次数。 在这种情况下，增加的延迟时间可能导致平均增加的退避时间。 延迟时间可以减少到更充分地利用TXOP的一定数量的TXOP之后的最小延迟时间。 TXOP的利用可以基于用于TXOP相对于可由接入点设置的TXOP限制的时间量来确定。

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for using different MAC addresses in frames for the same station to indicate how to process the frames. In this manner, frames for IEEE 802.11ac can carry information not present in legacy frames (e.g., frames according to IEEE 802.11a/n), but these frames may be interpreted by legacy devices in a legacy way. One example method generally includes receiving a first frame comprising an indication of a first MAC address and processing the received first frame based on the first MAC address. For certain aspects, the method further includes receiving a second frame comprising an indication of a second MAC address, wherein the second MAC address is different than the first address; and processing the received second frame based on the second MAC address, such that the processing of the second frame is different than the processing of the first frame.

Abstract: A network device can implement functionality for dynamically varying the total back-off duration. The network device can determine a total transmit duration for transmitting data from on a communication medium. If the total transmit duration exceeds a predetermined transmit interval associated with the data, the network device can determine the total back-off duration based, at least in part, on the total transmit duration and the predetermined transmit interval. The network device can initiate the total back-off duration by deferring data transmission on the communication medium during the total back-off duration. In some embodiments, if the network device implements multiple consecutive back-off intervals, the network device can determine whether to vary the duration of a second back-off interval depending on whether a transmission by another network device is detected on the communication medium after a first back-off interval elapses.

Abstract: Systems, methods, and devices for communicating in a wireless network are provided. In one aspect, a non-zero portion of a node identifier may be used to generate a partial association identifier. If no portion of the node identifier can be determined to be non-zero, then a default value may be used for the partial association identifier. In some other aspects, the partial association identifier may be based on a random number. In some other aspects, a portion of a node identifier is evaluated to determine if it is zero. If the portion is non-zero, a partial association identifier is generated based on the portion. If the portion is zero, a partial association identifier is generated based on the portion.
