摘要： PROBLEM TO BE SOLVED: To improve the standby time of a station in a wireless network.SOLUTION: An access point advertises or conveys a maximum listen interval and/or an association timeout supported by that access point. A station operates in a power-save mode and wakes up every listen interval to receive a beacon and any potential traffic for the station. The station selects a suitable listen interval on the basis of the maximum listen interval. The station is dormant for a longer duration than the listen interval and becomes active at least once in every association timeout in order to keep the association with the access point alive.

摘要： PROBLEM TO BE SOLVED: To provide a wireless media access control which supports asynchronous communication.SOLUTION: A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. A monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may originally have been transmitted during the scheduled transmission period. A wireless media access control supports asynchronous communication and overlapping transmissions. A wireless node may determine whether to request or schedule a transmission on the basis of control messages it receives from neighboring nodes. Data and control information is transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

摘要： PROBLEM TO BE SOLVED: To provide techniques to support beamforming for stations in a wireless network.SOLUTION: A station supports beamforming with implicit or explicit feedback by responding to training request though sending a sounding frame, and by responding to request for explicit feedback. In one explicit beamforming embodiment, the station sends a first frame with an explicit feedback request and also sends a Null Data Packet (NDP) having at least one training field but no data field. The station receives a second frame with explicit feedback, which may be derived based on the NDP. The station derives steering information based on explicit feedback and then sends a steered frame with beamforming based on the steering information. The station performs implicit beamforming using NDP for sounding.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling a traffic stream between mesh points in a mesh network. SOLUTION: Data arriving from the mesh point are aggregated in packet queues (814). The packet queues segregate arriving data by the Quality of Service (QoS) requirement of the data. An appropriate communication channel is selected. The communication channel is accessed through a contention access schema (808). An M-Request-To-Send (MRTS) message is sent to a potential receiving mesh point, and a receiving mesh point responds with an M-Clear-to-Send (MCTS) message (812). Data from the packet queues are transmitted to the next mesh point (814). A mesh point power save mode makes a battery-operated mesh point sleep, thus preserving power. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide encoding of an audio video stream that is transmitted over a network, for example, a wireless or IP network such that an entire frame of audio and an entire frame of video are transmitted simultaneously within a period required to render the audio video stream frames by an application in a receiver. SOLUTION: This encoding includes receiving audio and video RTP streams and assigning an entire frame of RTP video data to communication channel packets that occupy the same period, or less, as the video frame rate. An entire frame of RTP audio data is assigned to communication channel packets that occupy the same period, or less, as the audio frame rate. The video and audio communication channel packets are transmitted simultaneously. Receiving and assigning RTP streams can be performed in a remote station, or a base station.

摘要： PROBLEM TO BE SOLVED: To provide a bandwidth allocation method detecting interference with other systems, and/or redeploying in an alternate bandwidth. SOLUTION: Higher bandwidth channels are deployed at channel boundaries being a subset of those for lower bandwidth channels, and restricted from overlapping. Interference is detected on a primary and secondary channels, or on a combination channel (1120). When interference is detected, a higher bandwidth basic service set is relocated to an alternate channel (1140), or the bandwidth is reduced to avoid the interference (1150). Stations may also monitor messages from alternate systems to make channel allocation decisions. COPYRIGHT: (C)2011,JPO&INPIT
