Abstract: Certain aspects of the present disclosure relate to including deferral information in postambles and midambles. An apparatus for wireless communications may generally include a processing system configured to generate a first frame having at least one of a midamble or a postamble that provides an indication of a request for a device to defer transmitting for a duration and an interface configured to output the first frame for transmission. Another apparatus for wireless communications may generally include a processing system configured to generate a frame having at least one of a midamble or a postamble designed to allow a device, after exiting a low-power state, to perform synchronization to the frame and an interface for outputting the frame for transmission. Including midambles and postambles in a frame allow for more reliable responses and may reduce throughput losses and interference.

Abstract: Methods, devices, and computer program products for optimally phase rotating duplicate frames in wireless LAN transmissions are disclosed. In one aspect, phase rotation sequences may be chosen in order to minimize a peak-to-average power ratio (PAPR) of a frame or data unit, or of a portion of a frame or data unit, where the frame contains a plurality of identical frequency segments, such as a duplicate frame. The method involves selecting a frame bandwidth, and then selecting a phase rotation sequence based upon the frame bandwidth. The method further includes generating a frame including a number of identical 1 MHz frequency segments, and rotating some of those segments relative to other segments, based on the selected phase rotation sequence. The method further includes transmitting the frame.

Abstract: An 802.11ac access point (AP) may be capable of communicating with both 802.11n (on 40 MHz band) and 802.11ac devices (on 80 MHz band). While the 802.11ac AP is communicated with 802.11n devices on 40 MHz band, the remaining 40 MHz band is wasted because the 802.11n devices are not capable of communicating on this band. The AP may operate as if it is two virtual APs, one capable of communicating with 802.11n devices on a first primary and a first secondary channels (basic service set 1—BSS1) and the second communicating with 802.11ac devices on a second primary and a second secondary channels (BSS2). Individual beacons may be sent for BSS1 and BSS2. The transmissions on BSS2 may be performed simultaneously with transmissions on BSS1. However, transmission on one channel and receiving on the second channel cannot happen simultaneously.

Abstract translation: 802.11ac接入点（AP）可以能够与802.11n（40MHz频带）和802.11ac设备（在80MHz频带）通信。 虽然802.11ac AP与40 MHz频段的802.11n设备进行通信，但由于802.11n设备无法在该频段进行通信，所以剩下的40 MHz频段是浪费的。 AP可以像两个虚拟AP一样操作，一个能够与第一主和第一辅助信道（基本服务集1-BSS1）上的802.11n设备进行通信，并且第二个与第二主要的802.11ac设备通信， 第二个次要信道（BSS2）。 可以向BSS1和BSS2发送个人信标。 BSS2上的传输可以与BSS1上的传输同时执行。 然而，在一个信道上的传输和在第二信道上的接收不能同时发生。
