摘要： 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.-

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Reduced signaling overhead is provided in an apparatus and method for communications within a mesh network. The communications involve using two different beacon signals. A peer beacon contains time synchronization and resource management information to maintain existing links among one or more neighboring peer stations, while a separate network discovery beacon contains mesh network profile information that identifies the mesh network to aid network discovery for wireless communication stations wanting to join the mesh network. Embodiments describe coordination between peer stations to determine which stations are to send the network discovery beacons, so that at any given period of time not all stations need to be transmitting the discovery beacons.

摘要： Wireless communication is performed in a wireless network by dividing up a data transmission interval (DTI) within the communication frame into a plurality of time slots based on determining the number of best sector directions from the AP to each STA in the wireless network. Each STA transmits only during this time slot, while the AP uses receiver beamforming and receives only from a single beamforming direction for each of these time slots. A time slot may be used by more than one STA if they are in the same best antenna sector direction from the AP, wherein they contend for access within this time slot.
