  • Publication number: 20240098574
    Abstract: A communication system is a communication system that includes first and second information processing devices. The first information processing device performs control such that a signal (which is a signal having backward compatibility) serving as an index by which the second information processing device receiving a frame stops the reception of the frame is transmitted to the second information processing device. The second information processing device performs control such that the reception of the frame is stopped based on the signal (which is a signal having backward compatibility) serving as an index by which reception of the frame is stopped when the frame transmitted from the first information processing device is received.

  • Patent number: 11895712
    Abstract: A wireless communication circuit for operating over a wireless local area network (WLAN) supporting carrier sense multiple access/collision avoidance (CSMA/CA) in which real time application (RTA) traffic and non-RTA traffic coexist. Channel time is scheduled for transmitting real-time application (RTA) traffic based on expected RTA packet arrival time, with the schedule being shared with neighboring stations. Schedule time is adjusted based on schedules of neighboring stations to prevent channel contention collisions of multiple RTA traffics contending for the channel. Various mechanisms are described for supporting RTA transmissions while reducing channel access latency and contention collision.

  • Publication number: 20240014861
    Abstract: A communication apparatus that performs cooperative transmission according to Joint Tx is provided. A communication apparatus configured to operate as an AP that transmits packets to a subordinate STA and an STA connected to another AP includes a storage unit including a transmission buffer that stores packets for each STA, and a control unit that controls processing for sharing information on a sequence number of a transmission buffer for each STA between the APs. The control unit collects the information on the sequence number of the transmission buffer of each STA of each AP, and controls processing for transmitting packets to each STA on the basis of a difference in information related to the sequence number of the transmission buffer of each STA between the APs.

  • Patent number: 11716784
    Abstract: A Real-Time Application (RTA) interface between the Medium Access Control (MAC) and Application (APP) layers of interworking communications in the OSI model for use in wireless local area networks (WLANs). The interface between MAC and APP layers can be utilized for RTA packets, while non-RTA packets can still use the regular OSI model. In initializing a new RTA session the APP layer communicates a set of requirements to the MAC layer. The MAC layer monitors the channel and measures key performance indicators (KPIs) and either accepts or rejects the request. The interoperability between the APP and MAC layers provide enhanced abilities to reduce RTA packet latencies, as well as other benefits.

  • Patent number: 11711847
    Abstract: Systems, apparatus and methods for wireless local area network (WLAN) communication which support real-time application (RTA) packets. The access point (AP) schedules multiple-user (MU) multiple-input-multiple-output (MIMO) transmissions for uplink (UL) or downlink (DL) for RTA packets by allocating resources to packet transmissions before RTA packet arrival. The AP contends for channel access before the expected time of arrival of the RTA packet in the DL or UL direction. The operations reduce RTA packet latency on the WLAN.

  • Patent number: 11665626
    Abstract: Multi-band signaling is described for reducing signaling overhead in an apparatus and method for communications within a mesh network. The communications involve using two different beacon signals on two different communication channels. Peer beacons are sent using directional millimeter-wave (mmW) communications to provide time synchronization and resource management information to maintain existing links among one or more neighboring peer stations. A separate network discovery beacon is sent over a sub-6 GHz communication channel, to provide mesh network profile information that identifies the mesh network to aid network discovery for wireless communication stations wanting to join the mesh network.

  • Patent number: 11375438
    Abstract: An apparatus and method for adaptive network discovery signaling. Information is collected in a database of events, such as the discovery of a new station. The event information (e.g., new station, antenna sectors, active links) is shared with a central coordinator, or other stations in the network. Based on events, at this or other stations, signal transmission forms are adapted, for example for transmitting the beacon signals and notification signals. Adaptations of signal transmission include changing how frequently signaling is performed, timing of signaling, adjusting beam width, and/or adjusting directionality.
