Abstract: In wireless communications, an access point may transmit a first frame to one or more stations. In response to the first frame, the station(s) may transmit a respective second frame to the access point. The access point may generate a beamforming report based on the second frame(s) received by the access point from the station(s). The access point may transmit a third frame(s) that includes the beamforming report to the station(s). The station(s) may generate a respective beamforming matrix based at least on the third frame(s). Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: In wireless communications, an access point may send a trigger frame to multiple stations. The trigger frame's payload may include a first content and a second content, where the first content is associated with a legacy signal field of an uplink frame, and the second content is associated with a non-legacy signal field of the uplink frame. In response to the trigger frame, one or more stations may generate the uplink frame(s) based on the trigger frame and transmit the uplink frame(s) to the access point. The uplink frame(s) may include a legacy signal field and a non-legacy signal field. The legacy field may include a length of the uplink frame(s) that is based on the first content. The non-legacy signal field may include a remaining transmission opportunity (TXOP) duration that is generated based on the second content. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: In wireless communications for multi-users, an access point may generate a first frame for allocating resources to a plurality of stations. The first frame may contain an indication as to whether a station(s) is allocated at least one of a set of resource units (RUs) of a plurality of RUs, such as a center 26-tone RU. The set of resource units may be based on a channel bandwidth of the wireless communications. The indication may be contained in a common block field of signal fields, such as a common block field of high efficiency (HE) signal content channel(s) of an HE signal field. The station(s) may receive the first frame and determine whether the one of the set of RUs is allocated. The station(s) may transmit a second frame to the access point based on resource allocation information in the first frame. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: In wireless communications for multi-users, an access point may transmit a first trigger frame to one or more stations. The first trigger frame may be for scheduling a first uplink multi-user transmission and may indicate a plurality of resources for indicating existence of data to be sent to the access point. The station(s) may process the first trigger frame received from the access point. In response to the first trigger frame, the station(s) may generate and transmit a respective first uplink frame to the access point. In some cases, the first uplink frame(s) from the station(s) does not have a data field and does have a signal indicating existence of data to be sent from the station(s) to the access point. The signal may be sent using a resource(s) of the plurality of resources. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: A method implemented by a first network device in a Wireless Local Area Network (WLAN) to provide Modulation Coding Scheme (MCS) feedback. The method includes selecting an MCS that is determined to have a highest data rate among a plurality of available MCSes that when used to transmit a frame having a reference payload size over a wireless communications link between the first network device and a second network device results in a frame error rate that is less than or equal to a threshold error rate for a given set of transmission properties, generating a frame having a Media Access Control (MAC) header, wherein a control field of the MAC header includes an indication of the selected MCS, and transmitting the generated frame to the second network device through a wireless medium.

Abstract: In wireless communications for a 20 megahertz (MHz) channel bandwidth, a first device may determine a high efficiency long training field (HE-LTF) mode. The first device may generate an HE-LTF symbol by using a portion or an entirety of an HE-LTF sequence corresponding to the channel bandwidth and HE-LTF mode. The first device may transmit, in the channel bandwidth, a high efficiency physical layer protocol data unit (HE PPDU) that includes the HE-LTF symbol. A second device may receive, in the 20 MHz channel bandwidth, a downlink HE PPDU that includes an HE-LTF symbol. The second device may obtain, from the HE-LTF symbol, a portion or an entirety of an HE-LTF sequence corresponding to the channel bandwidth and an HE-LTF mode of the HE-LTF symbol. The downlink HE PPDU may be the HE PPDU from the first device. Other methods, apparatus, and computer-readable media are also disclosed.
