Abstract: A method for configuring channel access parameters in a wireless communication system includes selecting an element identification (ID) from a plurality of element IDs. Each of the plurality of element IDs identifies an enhanced distributed channel access (EDCA) parameter set element comprising at least one channel access parameter for at least one subset of wireless devices in a group of wireless devices. The selected element ID is identifiable by wireless devices of the group of wireless devices and not identifiable by other wireless devices. The method further includes generating the EDCA parameter set element for setting the at least one channel access parameter for each wireless device in the at least one subset. The EDCA parameter set element includes the selected element ID. The method further includes transmitting the EDCA parameter set element to at least one wireless device in the at least one subset of wireless devices.

Abstract: A method includes sending, from a first transmitter to a first receiver, a request to send (RTS) message associated with a first transmit opportunity (TXOP). The RTS message requests the first receiver to indicate whether reuse of the first TXOP is permitted. The method further includes receiving, at the first transmitter from the first receiver, a clear to send (CTS) message responsive to the RTS message.

Abstract: Systems and methods are disclosed that may provide for selective multi-user uplink (UL) of data for wireless devices. For example, a first wireless device may request permission to initiate a UL transmission to a second wireless device. The first wireless device may then receive, from the second wireless device, permission to initiate the UL transmission according to a multi-user (MU) UL protocol, determine a threshold duration for the UL transmission, and transmit UL data to the second wireless device according to the MU UL protocol and the threshold duration.

Abstract: An acknowledgment (ACK) frame has two parts: a group ACK part and a scheduling information part. In the group ACK part, an ACK/NACK indicator is included for a previous uplink (UL) transmission per station (STA). In the scheduling information part, information included for the following UL transmission per selected STA may comprise, for example, one or more of: a number of selected STAs, a media access control (MAC) address of each selected STA, a data transmission duration per selected STA, a transmission rate per selected STA, a request transmission duration, a pilot transmission order, or a STA transmission order.

Abstract: Systems, methods, and apparatuses for signaling and generating an enhanced random access frame in a wireless network are provided. One aspect of this disclosure provides a method of wireless communication. The method includes receiving, at a first device, a first frame from a second device indicating one or more frequency bandwidths available for random access by the first device. The method further includes transmitting, at the first device, a second frame to the second device in response to the first frame, the second frame comprising an indication of an identifier of the first device and indicating a selection of at least one frequency bandwidth of the one or more frequency bandwidths, the second frame not including a medium access control (MAC) payload data portion.

Abstract: Methods, devices, and computer program products for traffic information signaling in a wireless communications network are disclosed. In one aspect, a method of wireless communication network is disclosed. The method includes selecting, from a variable number of control fields, one or more control fields for inclusion in a frame. The method further includes generating the frame comprising the selected number of control fields, each control field comprising an end of control field, the end of control field storing an indicator indicative of an end of the selected number of control fields or a presence of another control field in the frame. The method further includes transmitting the frame.

Abstract: Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a MAC header with a frame control field. The sub-fields included in a particular frame control field may be based on the type of information to be communicated to the receiving device.

Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a first user terminal. The first user terminal receives, on a first DL communication channel of multiple DL communication channels, a DL MU PPDU includes MPDUs transmitted from an access point to multiple user terminals including the first user terminal on the multiple DL communication channels. The first user terminal obtains an UL channel indication and a BA indication. The first user terminal transmits, on a first UL communication channel of multiple UL communication channels, a first BA to the access point based on the UL channel indication and the BA indication simultaneously or concurrently with a BA transmission from the rest of the multiple user terminals to the access point on the rest of the multiple UL communication channels. The first BA acknowledges one or more of the MPDUs.

Abstract: Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.
