Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station. The AP may communicate with the station based on the modified uplink communication scheme.

Uplink flow control

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.

Reception of management frames for multiple basic services sets (BSSs)

An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.

Random access resource unit allocation for a multiple BSSID network

This disclosure provides methods, devices and systems for acknowledgement and retransmission, and more specifically, to methods, devices and systems that enable a secondary wireless channel to provide acknowledgements of data transmitted on a primary wireless channel concurrently with the reception of additional data on the primary wireless channel. In some implementations, a transmitting device may transmit wireless packets including multiple codewords to a receiving device via a first wireless channel. The receiving device may attempt to decode the received codewords based on primary information in the codewords. The receiving device may then transmit to the transmitting device, via a second wireless channel, a codeword acknowledgement that identifies codewords that the receiving device did not successfully decode. The transmitting device may then transmit parity information to the receiving device via the first wireless channel that aids the receiving device in decoding the identified codewords.

Acknowledgement and retransmission techniques utilizing secondary wireless channel

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). A first WLAN device may generate a first HARQ packet for transmission to a second WLAN device. The first WLAN device may determine a first basic service set (BSS) indicator and a second BSS indicator for a BSS associated with the first WLAN device and the second WLAN device. The first BSS indicator and the second BSS indicator may be indicative of a BSS identifier (BSSID) of the BSS. The first WLAN device may output the first HARQ packet for transmission to the second WLAN device. The first HARQ packet may include the first BSS indicator and the second BSS indicator in one or more fields of a physical layer (PHY) header of the first HARQ packet.

Hybrid automatic repeat request (HARQ) with basic service set (BSS) and station identification

Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to an apparatus for wireless communications. The apparatus generally includes an interface for communicating with a plurality of wireless nodes via a plurality of antennas, and a processing system configured to determine a power state of each of the plurality of wireless nodes, and change from a first antenna mode used for communicating with the wireless nodes using a first number of spatial streams to a second antenna mode used for communicating with the wireless nodes using a second number of spatial streams, based on the determined power states of the wireless nodes.

Systems, methods, and apparatuses for signaling and generating variable length block acknowledgement fields in a wireless network are provided. One aspect of this disclosure provides a method of wireless communication. The method includes generating, by an apparatus, a block acknowledgment (BA) frame comprising a BA bitmap field. The method further includes determining a size of the BA bitmap field. The method further includes inserting an indication of the determined size of the BA bitmap field.

Systems and methods for signaling and generating variable length block acknowledgment fields in a wireless network

Methods and apparatuses for providing closed-loop power control during a short inter-frame space (SIFS) burst are described herein. A method includes receiving feedback associated with transmit power used to transmit a first data packet in a SIFS burst. The method also includes adjusting at least the transmit power, or a modulation and coding scheme (MCS), or a combination thereof, used to transmit a second data packet of the SIFS burst based at least in part on the received feedback.

Techniques for managing SIFS-bursting in WLAN system

In some examples, a method includes receiving, at a second device of a data link group of a neighbor aware network (NAN), a message including an indication of whether a first device corresponding to a particular service is available during a particular time period during which devices of the data link group are configured to operate in an active operating mode. The method also includes transitioning to a low-power operating mode during one or more transmission windows corresponding to the particular time period in response to determining that the first device is unavailable during the particular time period.

Communication between devices of a neighbor aware network

An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random resource units (RUs) to only the selected BSS, and may transmit a frame indicating the allocation of the one or more random RUs to the selected BSS. Wireless devices belonging to the selected BSS may contend for access to the random RUs allocated by the frame, and then transmit uplink data using the random RUs.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating on a radio frequency spectrum band of a first radio access technology (RAT) using a set of antennas. The UE may reconfigure at least one antenna of the set of antennas to perform a first scan on the radio frequency spectrum band of a second RAT. The UE may determine, based on the first scan, whether to reconfigure a remaining portion of the antennas of the set of antennas to perform a second scan on the radio frequency spectrum band of the second RAT.
