    Abstract: Methods, systems, apparatuses, and devices are described for contention resolution techniques for medium access using a spatial dimension, a frequency dimension, or a combination of the both. A wireless station may determine that an access timer associated with backoff operations has expired. The wireless station may identify a domain index associated with the frequency domain, the spatial domain, or a combination. The wireless station may access the wireless medium according to the identified domain index. The wireless station may, prior to sending other transmissions, transmit a trigger frame including information associated with the resources of the wireless medium that are reserved for communications. Other wireless stations may share the medium and use the free resources.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for the coexistence of 1 MHz and 2 MHz operation modes within a wireless communication system in accordance with IEEE 802.11ah, for example. One example method generally includes scanning a plurality of channel pairs, wherein each of the channel pairs comprises a first channel having a first channel designation and a second channel having a second channel designation; determining, based on the scan, a set of open channels from the plurality of channel pairs in which no other apparatus is operating; selecting a primary channel based on the determination; and transmitting using the selected primary channel. The selection of the primary channel involves channel selection rules disclosed herein.

    Abstract: In a dense network, a node (e.g., a station) may receive beacons from a large number of access points. This may result in the node receiving a large quantity of beacons, which may affect the node's ability to efficiently utilize the communication medium. Thus, in some embodiments, the node may be capable of detecting or determining a beacon load it sees from one or more access points and determine if its beacon load is equal to or above one of a total beacon load threshold or an individual access point beacon load threshold. The total beacon load threshold or the individual beacon load threshold may be determined by at least one of the node, the access points, the user, or the network, and the node may request each access point from which the node receives beacons to reduce its beacon load.

    Abstract translation: 在密集网络中，节点（例如，站）可以从大量接入点接收信标。 这可能导致节点接收大量的信标，这可能影响节点有效利用通信介质的能力。 因此，在一些实施例中，节点可以能够检测或确定从一个或多个接入点看到的信标负载，并确定其信标负载是否等于或大于总信标负载阈值或单个接入点信标之一 负载阈值。 总信标负载阈值或单个信标负载阈值可以由节点，接入点，用户或网络中的至少一个确定，并且节点可以请求节点接收信标的每个接入点以减少其 信标负载。

    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。
