Abstract: A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action frame, management frame, CSI frame, control frame, or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.

Abstract translation: 公开了一种在无线局域网中提高交换管理和控制帧响应性的方法和系统。 发起者向响应者发送帧（动作帧，管理帧，CSI帧，控制帧或数据帧）。 在正确接收到帧时，响应者向发起者发送响应帧，而​​不是直接发送确认（ACK）分组。 响应者优选地访问无线介质以以短的帧间间隔（SIFS）发送响应帧。 利用这种方案，避免了与必须争取无线介质发送响应帧相关联的长延迟，因此反馈机制的响应性和及时性得到显着增强。 响应帧可以搭载在另一个分组上或与另一分组聚合。

Abstract: A method and apparatus may be used to broadcast a first beacon and a second beacon in a beacon interval. The first beacon may include an indicator that indicates whether a second beacon will be transmitted within the beacon interval. The first beacon may be a legacy beacon and the second beacon may be a non-legacy beacon. A legacy beacon may be decodable by any station (STA) and a non-legacy beacon may be decodable only by non-legacy STAs.

Abstract: A method and apparatus may be used for assigning groups of stations in wireless communications to one or more groups. Groups may be assigned by an access point (AP) based on information received from a station (STA). Group information may be signaled to each station and a group identifier may be indicated in a frame. The group information may be applied to a performance enhancement, for example power savings for the station, wherein the station enters a power saving mode on a condition that the station determines that it is not a member of the group.

Abstract: A method for use in a station of measuring radio frequency (RF) interference is presented. An average noise power indicator of the STA (STA_ANPI) is determined. A rate of change of the STA_ANPI is monitored to determine an RF interference metric. The RF interference metric is transmitted to another network entity, whereby the another network entity is enabled to perform load balancing based on the RF interference metric.

Abstract: A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.
