Provided is a communication device that performs multi-link operation by synchronous transmission. A communication device includes a communication unit that performs communication by a first link and a second link, and a control unit that controls a communication operation by the communication unit, in which the control unit sets an occupancy period of the second link on a basis of transmission suppression information of the first link. When a remaining time of a transmission suppression period of the first link is longer than a first threshold, the control unit performs control to set an occupancy period of the second link until the transmission suppression period of the first link ends and transmit a data frame by the second link.

Communication device and communication method

Reception of a frame is appropriately stopped. 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.

Information processing device, communication system, and information processing method

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.

RTA interface between MAC and app layer

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.

MU-MIMO pre-packet arrival channel contention

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.

Multi-band millimeter wave network discovery

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.

[Solution] Provided is a communication apparatus, including: a processing unit configured to select one of a frame of a first format including a training signal and a frame of a second format not including a first field which is at least a part of the training signal, and generate the frame of the selected format; and a communication unit configured to transmit the frame of the first format or the frame of the second format. Also provided is a communication method, including: selecting one of a frame of a first format including a training signal and a frame of a second format not including a first field which is at least a part of the training signal, and generating the frame of the selected format; and transmitting the frame of the first format or the frame of the second format.

Communication apparatus and communication method

An electronic device including circuitry configured to perform control in a manner that a Physical Layer Convergence Protocol (PLCP) header format is selected from a plurality of PLCP header formats; and append the selected PLCP header to a physical layer packet for transmission.

Information processing apparatus and information processing method

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.

Mobile object and storage medium

A wireless communication circuit configured for communicating over a wireless local area network (WLAN) in its reception area to communicate real-time application (RTA) packets as well as non-real time (non-RTA) packets while utilizing carrier sense multiple access/collision avoidance (CSMA/CA). An RTA scheduling table is utilized for tracking active RTA sessions and managing transmission times for RTA traffic. Scheduling of channel time based on the expected RTA packet arrival time, and rejecting other packet transmissions during the scheduled channel time for RTA packet.

Reserving future channel time for handling of real time application (RTA) packets on wireless local area network

An electronic device forming part of a communication system includes first processing circuitry configured to receive a beacon from a counterpart device. The communication system also includes second processing circuitry that causes the counterpart device to set a transmitting and receiving operation as active state for a first operating period.

Communication method, communication device, and computer program

A WiFi communications mechanism in which simultaneous transmission is negotiated and beamforming communications performed towards at least one station (STA), while nulling is performed towards one or more other access points (APs) to reduce interference. Omni-directional transmissions are utilized in a manner to overcome preamble interferences, which is used in combination with synchronizing symbol intervals to eliminate interference from symbol transitions. The enhanced simultaneous transmission protocol allows two APs to transmit simultaneously without interfering with one another.

Downlink orthogonal frequency-division multiplexing (OFDM) beamforming simultaneous transmission

A wireless communication apparatus/system/method utilizing directional transmission over a mmW band performing transmission of signals on a sub-6 GHz band that aids scanning for mmW mesh network discovery. A new node sends an assistance request on the sub-6 GHz band. The network node responds to the assistance request by sending an assistance response on the sub-6 GHz band. Upon exchanging the discovery assistance request and response with the network node on the sub-6 GHz band, the new node switches to the mmW band to discover neighbor(s). The network node upon exchanging the discovery assistance request and response on the sub-6 GHz band switches to mmW band to discover new nodes. Implementations can provide assistance directly or in response to cooperation between network stations.
