    Abstract: Certain aspects of the present disclosure provide methods and apparatus for uplink (UL) multiuser multiple-input, multiple-output (MU-MIMO) transmissions in a High Efficiency WLAN (HEW) system. One example method generally includes generating a packet having a preamble portion and transmitting the packet. The preamble portion typically includes a long training field (LTF); a first signal (SIG) field subsequent to the LTF; one or more other LTFs located subsequent to the first SIG field; and at least one second SIG field, wherein all SIG fields in the preamble portion, other than the first SIG field, are subsequent to the one or more other LTFs. Another example method generally includes receiving, from an apparatus, a packet having a preamble portion comprising tone-interleaved LTFs; and performing frequency offset adjustment on the packet based on the tone-interleaved LTFs.

    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。
