  • Publication number: 20200076551
    Abstract: Methods, systems, and devices for wireless communications are described for coordination between multiple access points (APs) for communications within a transmission opportunity (TxOP). A first AP may gain channel access for a TxOP, and may coordinate with at least a second AP to allow both the first AP and the second AP to transmit and receive wireless communications during the TxOP. The first AP, upon gaining channel access following a successful contention-based channel access procedure, may initiate a scheduling phase with the second AP to schedule of resources within the TxOP for the first and second APs. The first AP may initiate a multi-AP coordinated transmission phase following the scheduling phase, during which both the first AP and second AP may communicate with one or more associated STAs.

  • Publication number: 20200045656
    Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.

  • Publication number: 20200029350
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing uplink access in a wireless local area network. A station (STA) may inform an access point (AP) of uplink quality of service (QoS) parameters for a traffic flow from the STA. The AP may control uplink resources to satisfy the QoS parameters. For example, the AP may select from among different access modes (including a single user (SU) access mode, an uplink multi-user (UL-MU) scheduled access mode, a multi-user enhanced distributed controlled access (MU EDCA) access mode, or a low latency (LL) access mode). The AP may cause the STA to use a SU access mode or the LL access mode if the UL-MU scheduled access mode and the MU EDCA access mode are not sufficient to satisfy the uplink QoS parameters for the traffic flow.

  • Publication number: 20200014509
    Abstract: This disclosure provides methods, devices, and systems for wireless communications. In some systems, an access point (AP) may assign a resource unit (RU) including a non-contiguous set of tones of a channel to a wireless node, such as a station (STA). The non-contiguous set of tones includes at least some tones that are non-contiguous in the frequency domain with all other tones of the set. The AP may generate an indicator for this RU and may transmit the indicator to the wireless node. The wireless node may receive the indicator, determine the non-contiguous set of tones for the indicated RU, and transmit data over the non-contiguous set of tones for the RU. The AP may receive the data via the RU (over the non-contiguous set of tones).

  • Patent number: 10530856
    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).

  • Publication number: 20190380117
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for per-station punctured transmissions. A wireless local area network (WLAN) device may determine available resource units (RUs) within a wireless channel that has a punctured frequency range. The WLAN device may allocate a plurality of RUs, from among the available RUs, for to include data for a same station. For example, a physical layer protocol data unit (PPDU) may include more than one RU for a first station. The RUs that are allocated to the first station may exclude the punctured frequency range. In some implementations, the plurality of RUs may be separated by at least the punctured frequency range. A signaling header in the PPDU may indicate which RUs are allocated to the first station. By allocating a plurality of RUs in a PPDU, a WLAN may support per-station puncturing within the PPDU.

  • Patent number: 10470174
    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.

  • Publication number: 20190327740
    Abstract: An access point (AP) may signal management frames that include two operation information fields indicating two channel widths for different classes of wireless stations (STAs). STAs may identify one of the two operation information fields based on capabilities of the STA (e.g., whether or not the STA is capable of dual band channel bonding, resource unit or physical channel puncturing, etc.). In some cases, one operation information field may indicate a channel width within a first and second frequency band (e.g., within the 5 GHz band and the 6 GHz band), as well as a puncturing scheme associated with the channel width. In some cases, the operation information field may indicate a dual band channel bonding configuration, where two frequency segments associated with the channel bonding configuration are in two different frequency bands. In some cases, a tightened spectral mask may be used for such dual band channel bonding configurations.

  • Publication number: 20190288895
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for communicating over a wireless communication network. A wireless communication device may be configured to generate and transmit a message according to a tone plan for transmission to multiple destination devices within one of a 240 or 320 MHz channel bandwidth. The message may include a short training field (STF) and a long training field (LTF). The STF may be used by a receiver to adjust an automatic gain control (AGC) function. The LTF may be used for channel estimation. In some implementations, the STF may have a data tone plan formed from a concatenated sequence of sub-STFs. A phase rotation applied to at least one of the sub-STFs of the concatenated sequence may reduce a peak-to-average-power ratio (PAPR) of the message as compared to a non-phase rotated concatenated sequence of sub-STFs.
