This disclosure provides methods, devices and systems for transmitting and receiving physical protocol data units (PPDUs) over multiple links. In some aspects, a wireless communication device may determine that first random back off (RBO) for a first channel of a first link has counted down to zero. A wireless communication device may determine, when the first RBO has counted down to zero, that a second RBO for a second channel of a second link has a count down remaining. A wireless communication device may optionally transmit a medium reservation message on the first link reserving a transmission opportunity (TXOP). A wireless communication device may determine whether to wait for the second RBO before transmitting on the first link. A wireless communication device may transmit at least a first PPDU on the first link during the TXOP.

Uplink (UL) aggregation for multi-link operation (MLO)

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

Certain aspects of the present disclosure provide an architecture and method for multi-link operation (MLO) at an access point (AP). The method generally includes obtaining a packet from at least one buffer and selecting a processing path, from first and second processing paths, for a packet to be routed from the at least one buffer to at least one of a plurality of radio components for wireless transmission to at least one peer via one or more links, wherein: the first processing path is configured to bind the packet to one of the one or more links based on at least one code-implemented rule, and the second processing path is configured to bind the packet to one of the one or more links based on instantaneous channel sensing.

Flexible multi-link operation architecture

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a time period to delay entering a power save mode (leak guard) for wireless communications. In one aspect, a wireless communication device may adjust a time period to delay entering a power save mode. The time period is associated with the wireless communication device remaining awake to prevent an access point from transmitting to the wireless communication device while the wireless communication device is in the power save mode. The wireless communication device also may provide, to the AP, an indication that the wireless communication device is entering a power save mode, and the wireless communication device may enter the power save mode. Entering the power save mode is at least the adjusted time period after providing the indication to the AP.

Adjustable leak guard for power save during wireless communications

Disclosed are methods and systems for wireless communication. In one aspect, a method includes generating, by an access point, a frame, the frame assigning first resource units to first devices participating in a multi-user transmission with the access point during a transmission opportunity, and further indicating second resource units available during the transmission opportunity for transmissions to other devices, transmitting the frame; and receiving the multi-user transmission from the first devices according to the resource unit assignments.

Methods and systems for improved resource unit utilization

Methods and apparatus for multiple user uplink are provided. In one aspect, a method includes receiving, at a wireless device, a trigger message allocating one or more wireless transmission resources, each resource allocated to a plurality of stations. The method further includes determining whether to transmit over the allocated resources based on a contention procedure. The method further includes selectively transmitting over the allocated resources based on said determining.

Methods and apparatus for multiple user uplink access

Aspects described herein relate to requesting and/or reporting channel feedback. A request for channel feedback can be generated by an access point, where the request includes an indicator specifying that the request uses a first format different from a second format, where the indicator corresponds to a bit of a station (STA) information field defined by the second format. The access point can transmit, and a STA can receive, the request for channel feedback.

Techniques for reporting channel feedback in wireless communications

Systems and methods for formatting frames in neighborhood aware networks are described herein. One aspect of the subject matter described in the disclosure provides a method of communicating in a wireless neighborhood aware network (NAN). The method includes determining at least one connection setup information element indicating one or more connection parameters of the NAN. The method further includes determining at least one service identifier of the NAN. The method further includes generating a public action discovery frame comprising the at least one connection setup information element and the at least one service identifier. The method further includes transmitting, at a wireless device, the public action discovery frame.

Systems and methods for formatting frames in neighborhood aware networks

Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes initiating a contention based process for transmitting a synchronization message during a discovery time interval of a discovery time period. The synchronization message includes a first timestamp of the wireless communication apparatus. The method further includes selectively transmitting the synchronization message based on a master preference value of the wireless communication apparatus.

Systems and methods for synchronization within a neighborhood aware network

Methods, apparatus, and computer readable storage mediums for enabling reduced power consumption in wireless devices operating in a neighbor aware network are disclosed. In one aspect, a method includes generating a first message, the first message indicating beacon transmit window information, the beacon transmit window information indicating a first time interval when one or more beacon messages are transmittable, and transmitting the first message on the neighbor aware network.

Systems and methods for synchronization within a neighbor aware network

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

A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device receives a first data signal via a first transceiver chain while concurrently initiating a transmission of a second data signal via a second transceiver chain of the wireless device. The wireless device suspends updates to one or more tracking loops of the first transceiver chain in response to initiating the transmission of the second data signal. The updates to the one or more tracking loops may be suspended prior to transmitting the second set of data from the second transceiver chain. The wireless device may subsequently resume updates to the one or more tracking loops of the first transceiver chain after completing the transmission of the second data signal.

Skip RX during SBS transmission

Methods, systems, and devices are described for wireless communication. In one aspect, a method of wireless communication includes determining a transmit time metric associated with each transmission group of a number of transmission groups based at least in part on an amount of data in a transmit queue and a modulation and coding scheme (MCS) data rate for at least one wireless communication device in the transmission group. The method also includes scheduling a transmission to a first transmission group of the number of transmission groups based at least in part on the transmit time metric for the first transmission group.
