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: A method and system for improving the accuracy of phase and frequency offset during multiple in multiple out (MIMO) channel estimation in a sounding procedure. The improved phase and frequency offset process selects resource allocation unit configuration to ensure a minimum pilot density from the available operation modes. A method for reducing the data in the feedback matrix of the sounding procedure correlates the long training frame (LTF) and number of groups (Ng) between the sounding frame and the feedback to improve efficiency in the amount of feedback that is returned.

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.

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: A method is implemented by a station (STA) in a wireless network to provide an uplink (UL) Orthogonal Frequency Division Multiple Access (OFDMA) acknowledgement. The method includes receiving a first Physical Layer Protocol Data Unit (PPDU), where a Media Access Control (MAC) header of a MAC Protocol Data Unit (MPDU) in the first PPDU includes a Simplified Scheduling Information subfield that carries scheduling information for scheduling the UL OFDMA acknowledgement. The method further includes generating a second PPDU that includes an acknowledgement frame, determining an uplink cyclic prefix length to apply to the second PPDU based on a cyclic prefix length of the first PPDU, where the uplink cyclic prefix length is longer than the cyclic prefix length of the first PPDU, and transmitting the second PPDU through a wireless medium according to the scheduling information, where the uplink cyclic prefix length is applied to the second PPDU.

Abstract: A process and system provides a high efficiency (HE) sounding procedure that enables a beamformer to signal to each beamformee support for responses allowing other forms of feedback from the beamformee instead of explicit feedback. The HE sounding procedure utilizes additional fields in the frames of the HE sounding procedure to signal the use of the HE sounding procedure. The HE sounding procedure also supports legacy stations that provide standard explicit feedback.

Abstract: The embodiments provide a method implemented by a network device for transmitting link adaptation feedback in a Wireless Local Area Network (WLAN) that supports multi-user simultaneous transmission. The method generates and transmits a frame that includes one or more link adaptation feedback values associated with a wireless communications link between the network device and a second network device. In one aspect, the one or more link adaptation feedback values may include a link adaptation feedback value for an entire operation bandwidth of the wireless communications link and a link adaptation feedback value for a given subchannel within the operation bandwidth. In another aspect, link adaptation feedback values for one or more users of a multi-user simultaneous transmission are transmitted in a multi-user acknowledgment (ACK) frame. The embodiments allow for efficient link adaptation in a multi-user simultaneous transmission environment.

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.
