Abstract: A method and an apparatus for wireless communication are provided. In one configuration, a first device may receive from a second device information indicative of a slot schedule for scheduling communication between the two devices. The slot schedule may allocate slots for the first device to transmit to the second device and for the second device to transmit to the first device. The information may indicate one or more types of message allowed or disallowed to be transmitted in the respective slots. The first device may determine based on the received information a chronologically first slot that is a first slot in time among all the slots allocated to the first device allowed to transmit an acknowledgement message. The first device may receive a first message from the second device. The first device may transmit an acknowledgement message in response to the received first message using the chronologically first slot.

Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an AP, that reduce the overhead associated with triggering an uplink transmission from the STA. In some examples, the STA may also calculate its transmit power by decoding a spatial reuse subfield of the trigger frame from the AP and identifying downlink pathloss measurements of the trigger frame. Accordingly, the STA may identify acceptable interference level of the AP and calculate a transmit power in order to minimize interference at the AP. In some aspects, the STA may transmit its uplink packets to a different AP on one or more punctured channels at the calculated transmit power of the STA.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for identifying frames or packets of data that were received in error (such as incorrectly decoded or not received at all) by a receiving device for purposes of retransmission. In one aspect, a wireless device may form a number of frames for wireless transmission. Each of the frames may include a frame header and may be associated with a unique sequence number. In some implementations, for each of the frames, the wireless device may embed at least a portion of the unique sequence number into a portion of a control field or a delimiter field of the frame header. In some other implementations, for each of the frames, the wireless device may signal at least a portion of the unique sequence number using bit locations unassociated with a sequence number field of the frame header.

Abstract: This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first access point (AP) may identify other APs to participate in a coordinated access point transmission session, may obtain a transmit opportunity (TXOP) for transmitting wireless signals over a frequency bandwidth, may allocate corresponding portions of the frequency bandwidth to the identified APs for downlink (DL) transmissions during the TXOP, may select a duration of the TXOP for the coordinated access point transmission session based at least in part on an amount or percentage of the first AP's frequency bandwidth that is allocated to the one or more identified APs for the coordinated access point transmission session, and may output information indicative of at least one of the selected TXOP duration or the corresponding portions of the frequency bandwidth allocated to the respective identified AP by the first AP.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer-readable media, for reporting Quality of Service (QoS) feedback information. A method of wireless communication at an apparatus may include selecting, from a variable number of control fields, one or more control fields for inclusion in a frame, each control field comprising a control identifier field and a control information field. The control identifier field may include an indicator indicating a type of information for communication is QoS feedback information. The control information field may include one or more subfields containing the QoS feedback information. The method may further include generating the frame comprising the selected number of control fields, and outputting the frame for transmission.

Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Various implementations relate generally to coordinated transmit power control for sharing time and frequency resources of a wireless medium. Particular implementations relate more specifically to coordinated access point spatial-reuse-multiple-access techniques for sharing the time and frequency resources of a transmission opportunity. According to such techniques, an access point that wins contention and gains access to the wireless medium for the duration of a transmission opportunity may limit the transmit powers of the access points selected to share the time and frequency resources such that interference from the selected access points does not prevent stations associated with the winning access point from successfully decoding packets transmitted by it.

Abstract: This disclosure provides methods, devices and systems for sharing time resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) techniques for sharing the time resources of a transmission opportunity (TXOP). According to such techniques, a coordinated AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time resources with other coordinated APs. To share its time resources, the winning AP may partition the TXOP into multiple TXOP segments each including respective time resources representing a sub-duration of the TXOP. For example, the winning AP may assign, grant or allocate (hereinafter used interchangeably) itself one or more of the time resources and also allocate each of one or more remaining time resources to one or more other ones of the coordinated APs.

Abstract: The present disclosure provides techniques for preamble puncturing in wireless local area networks (WLANs). In one implementation, an access point (AP) can identify, within a channel width, one or more bandwidth regions associated with incumbent technologies. The AP can broadcast or advertise, to a basic service set (BSS) initiated or started by the AP, a preamble puncture pattern in one or more management frames, the preamble puncture pattern being based on the bandwidth regions associated with incumbent technologies. In another implementation, an AP can identify a single user (SU) preamble puncture transmission, and can signal in a common portion of a SIG-B field of a multi-user (MU) PPDU format that a resource unit (RU) size is assigned to a same user to indicate the SU preamble puncture transmission. Although these techniques may be used in any frequency band, typical frequency bands may include, but are not limited to, a 2.4 GHz band, a 5 GHz band, and/or a 6 GHz band.

Abstract: In an embodiment, a first media presentation session is established between a first Source and the Sink, and a second media presentation session between a second Source and the Sink. First and second media streams are streamed to the Sink by the first and second Sources, respectively. The Sink presents the first and second media streams in respective portions of a display screen, and detects user input at the Sink that is indicative of a trigger to transfer data originated from the first Source to the second Source. The Sink coordinates with one or both of the first Source and the second Source to facilitate the data to be delivered to the second Source in response to the detection. As a result of the coordination, the second Source receives the first Source-originated data (e.g., from the first Source directly, or via the Sink).
