  • Publication number: 20220394726
    Abstract: System and method of cooperative multi-band wireless STA communication that enables full duplex operations are disclosed herein. Frames are configured to carry band information and are selected to be transmitted simultaneously in multiple bands based on various constraints to avoid out-of-order delivery. For frames under a block ACK agreement, a transmit STA can specify the transmission bands for the frames in an ADDBA request frame. While a first band is transmitting a first frame under a block ACK agreement, the second band can be used to transmit a frame under the same block ACK agreement as, and from the same traffic flow with, the first frame. Otherwise, the second band can be used to transmit a frame with a different TID than the first frame.

  • Patent number: 11411635
    Abstract: Systems and methods of WLAN communication including efficient spatial reuse mechanisms for relay transmissions between a repeater network and non-AP STAs in OFDMA. The non-AP STAs are grouped based on their connectivity with the individual repeaters and the radio coverage regions of the repeaters. Each group is either a non-overlapping group with the constituent non-AP STAs located in a non-overlapping coverage region of a particular repeater, or an overlapping group with the constituent non-AP STAs located in an overlapping coverage region of two or more repeaters. Based on the grouping, certain RUs (or subchannels) are reused for multiple groups without causing inter-group interference, thereby expanding the bandwidths used in the relay operations. RU allocation based on grouping can be used in combination with transmit power adjustment to achieve efficient spatial reuse in OFDMA.

  • Publication number: 20210352715
    Abstract: A first station (STA) in a non-access point (non-AP) multi-link device (MLD), which has a constraint on simultaneous transmission and reception (TX/RX) on the first link and the second link, receives a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) on a first link or a second link. In response to the PPDU meeting a condition, one or more other STAs of a plurality of STAs in the non-AP MLD are refrained from performing an operation.

  • Publication number: 20210144589
    Abstract: Multi-link operations can provide higher network throughput and improved network flexibility compared to traditional techniques for wireless communication. Embodiments of the present invention provide techniques for simultaneously transmitting frames of an A-MSDU over multiple links in a multi-link operation between wireless devices (e.g., a wireless STA and a wireless AP). The A-MSDU can be aggregated to satisfy capability requirements of the transmitting device and/or the receiving device. Moreover, the A-MSDU can be fragmented, for example, to satisfy an MPDU length requirement of the transmitting device and/or the receiving device. Some embodiments disclosed herein use a virtual mac address of an LLC sublayer interface to define parameters values of an A-MSDU sub-frame header (e.g., SA and DA) for routing the respective frame to the LLC sublayer interface of the receiving device.

  • Patent number: 10972963
    Abstract: Systems and methods of providing Basis Service Set (BSS) load information pertinent to multi-user (MU) communications in WLAN systems. An access point (AP) can determine the counts of MU-capable user stations (STAs) active STAs in a BSS. Each MU-capable STA is configured for Multi-User Multiple-Input Multiple-Output (MU-MIMO) communications and/or Orthogonal Frequency-Division Multiple Access (OFDMA) communications. The AP can further determine ratios of PPDU time over an observation period of MU uplink (UL) and downlink (DL) communications, respectively. The AP can further determine an underutilization level of each available frequency subband, the underutilization level integrating the actual underutilization in terms of both spatial streams and frequency subbands. The DL and UL underutilization levels can be separately determined and reported. The MU BSS load information can be included in a beacon frame as a BSS load information element and distributed to user STAs periodically.

  • Patent number: 10869232
    Abstract: Embodiments of the present invention provide a method and apparatus for announcing the expected delay period between when a wireless AP stops transmitting on a first channel and begins transmitting on a second channel. After the last beacon frame is send on an old channel, a delay is experienced between transmitting the last frame on the old channel and transmitting the first frame on the new channel, where the delay varies based on the implementation of the AP and any CAC that must be performed on the new channel before broadcasting. Therefore, embodiments of the present invention provide an expected channel switch time element, for example, in a beacon frame or probe response frame.

  • Publication number: 20200314789
    Abstract: Embodiments of the present invention provide an apparatus and method for enrolling a wireless AP into a Multi-AP (MAP) wireless network. By enrolling multiple wireless AP in a MAP wireless network, the wireless APs can cooperate to efficiently service wireless STAs and advantageously mitigate signal interference and degradation do to walls, structures, objects, etc. To enroll a new wireless AP into an existing MAP wireless network, the new wireless AP is authenticated and configured into the MAP network using a wireless device with ‘controller’ functionality (a “controller device”) that can act as a ‘Device Provisioning Protocol (DPP) configurator.’ A DPP-capable smartphone can perform DPP authentication and configuration without using a proprietary smartphone application. In this way the burden on both the user and the equipment manufacturer is reduced because a propriety smartphone application is not needed to enroll the new wireless AP.

  • Publication number: 20200120603
    Abstract: Power management operations are performed by devices communicating using multiple bands simultaneously where a first wireless band can be used to send and receive power management control frames for use on a second wireless band of a wireless network. In this way, a device that is in a sleep or dose power management state on a first band can be instructed to enter an awake power management state on the first band based on a communication received over a second band that is currently active and receiving data. Embodiments of the present invention enable power to be conserved when a band is not currently being used, or when there is no more data available (buffered) for a specific band.
