Abstract: PROBLEM TO BE SOLVED: To provide techniques for quickly sending feedback information for beamforming.SOLUTION: A transmitter sends a first frame comprising training symbols. A receiver receives the first frame, determines the amount of time to generate feedback information, and determines the amount of time to send the feedback information. The receiver then determines the length of a second frame based on the amount of time to generate and send the feedback information. The receiver sends the second frame after waiting a short interframe space (SIFS) period from the end of the first frame, without performing channel access. The receiver generates the feedback information based on the training symbols and sends the information in the second frame when ready. The transmitter receives the second frame, derives at least one steering matrix based on the feedback information, and sends a third frame with the at least one steering matrix.

Abstract: PROBLEM TO BE SOLVED: To provide pilots suitable for use in MIMO (multiple-input multiple-output) systems and capable of supporting various functions. SOLUTION: Various types of pilots include: a beacon pilot, a MIMO pilot, a steered reference or steered pilot, and a carrier pilot. The beacon pilot is transmitted from all transmit antennas and can be used for timing and frequency acquisition. The MIMO pilot is transmitted from all transmission antennas but is covered with different orthogonal codes assigned to the transmission antennas. The MIMO pilot can be used for channel estimation. The steered reference is transmitted on specific eigenmodes of a MIMO channel and specific to a user terminal. The steered reference can be used for channel estimation. The carrier pilot can be transmitted on designated sub-bands/antennas and can be used for phase tracking of a carrier signal. Various pilot transmission schemes can be devised based on different combinations of these various types of pilots. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and an instrument for measuring channel condition information and reporting; in a high efficiency communications system. SOLUTION: A channel condition information (CSI) can be used by the communications system between a transmitting device and a receiving device for preparatory condition transmission. A group of subchannels, having no element in common, are assigned to a transmitting antenna, of which the source position of the transmitting device is decided. A pilot symbol is formed in a subset of a subchannel having no elements in common and is transmitted. When the receiving device receives the transmitted pilot symbol, it decides CSI for the subchannel having no elements in common, which has reported the pilot symbol. The amount of information required for reporting to CSI on a reverse link can be further minimized via a compression technology and a resource allocation technology. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for measuring and reporting channel state information in a high efficiency, high performance communications system.SOLUTION: Channel state information (CSI) can be used by a communications system 100 for precondition transmissions between transmitter units and receiver units. Disjoint sub-channel sets are assigned to transmit antennas located at a transmitter unit. Pilot symbols are generated and transmitted on a subset of the disjoint sub-channels. Upon receipt of the transmitted pilot symbols, the receiver units determine the CSI for the disjoint sub-channels that carried pilot symbols. The amount of information necessary to report CSI on the reverse link can be further minimized through compression techniques and resource allocation techniques.

Abstract: PROBLEM TO BE SOLVED: To provide channel estimation and spatial processing for a TDD MIMO system.SOLUTION: Calibration may be performed (512) to address differences in the responses of transmission/reception chains at an access point and a user terminal. A MIMO pilot is transmitted (522) on a first link and used (524) to derive an estimate of the first link channel response, which is decomposed to obtain a diagonal matrix of singular values. A first unitary matrix contains (526) both left eigenvectors of the first link and right eigenvectors of a second link. A steered reference is transmitted (530) on the second link using the eigenvectors in the first unitary matrix, and is processed to obtain the diagonal matrix. A second unitary matrix contains (532) both left eigenvectors of the second link and right eigenvectors of the first link. Each unitary matrix may be used to perform spatial processing (540, 542, 550, 552).
