Abstract: In one embodiment, a method for setting a clear channel assessment (CCA) threshold includes receiving, by a station from a first access point, a first message including an information element and determining a CCA threshold in accordance with the information element. The method also includes detecting a power level of a channel between the station and the access point to produce a first detected power level and comparing the first detected power level and the CCA threshold. Additionally, the method includes transmitting, by the station to the first access point on the channel, a second message when the detected power level is less than the CCA threshold.

Abstract: A system and method are provided for traffic signaling in wireless or sensor networks. The system and method use information or bits in a Signal Field (SIG) of Physical Layer (PHY) preamble in a packet to provide traffic control information. An embodiment method implemented by a network component comprises indicating a traffic direction and a traffic type for traffic control in a SIG in a frame and transmitting the frame including the SIG. Another method comprises receiving in a frame a SIG for traffic control that indicates a transmission type and decoding the SIG field to determine whether to process remaining information in the frame if the frame comprises data payload or a Media Access Control (MAC) header.

Abstract: A system and methods are provided to enable differentiated association of stations (STAs) in a WiFi system and provide differentiated quality of service (QoS) based association. The embodiments include categorizing STAs that share a channel of the WiFi network into different association priority classes, wherein the STAs with higher association priority classes wait for shorter times before starting association with an access point (AP) over the shared channel. The association priority classes are assigned by the AP or the WiFi network and signaled to the STAs. Alternatively, the association priority classes are assigned by the STAs and indicated to the AP or the WiFi network. The association priority class is determined for a STA according to traffic type, device type, subscriber type, or a random number generator.

Abstract: It is possible to shorten channel monitoring periods of unoccupied channels during Wi-Fi discovery by verifying whether or not a message indicating the presence of a Wi-Fi AP has been detected prior to the probe timer reaching a medium channel time (MedChannelTime). For example, STAs detecting some channel activity during the clear channel assessment may nevertheless discontinue monitoring a Wi-Fi Channel when no messages indicating the presence of a Wi-Fi AP are detected prior to expiration of the MedChannelTime. Messages indicating the presence of a Wi-Fi AP may include any Wi-Fi messages sent from or destined for a Wi-Fi AP, while excluding probe requests and non-Wi-Fi messages.

Abstract translation: 通过在探测定时器到达中等信道时间（MedChannelTime）之前，验证是否已经检测到指示存在Wi-Fi AP的消息，可以缩短Wi-Fi发现期间未被占用信道的信道监视周期。 例如，当在MedChannelTime期满之前没有检测到指示存在Wi-Fi AP的消息时，在清除信道评估期间检测一些信道活动的STA可能会中止监视Wi-Fi信道。 指示Wi-Fi AP的存在的消息可以包括从Wi-Fi AP发送或者去往Wi-Fi AP的任何Wi-Fi消息，而不包括探测请求和非Wi-Fi消息。
