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).

Abstract: PROBLEM TO BE SOLVED: To provide a method for supporting multiple spatial multiplexing (SM) modes.SOLUTION: For data transmission, multiple data streams are coded and modulated in accordance with their selected rates to obtain multiple data symbol streams. These streams are then spatially processed in accordance with a selected SM mode (e.g., with a matrix of steering vectors for the steered mode and with the identity matrix for the non-steered mode) to obtain multiple transmit symbol streams for transmission from multiple antennas. For data reception, multiple received symbol streams are spatially processed in accordance with the selected SM mode (e.g., with a matrix of eigenvectors for the steered mode and with a spatial filter matrix for the non-steered mode) to obtain multiple recovered data symbol streams. These streams are demodulated and decoded in accordance with their selected rates to obtain multiple decoded data streams.

Abstract: 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

Abstract: PROBLEM TO BE SOLVED: To provide a steering vector which is used by a terminal for transmission on the uplink by obtaining and decomposing an uplink channel response matrix for each terminal. SOLUTION: An "effective" uplink channel response vector is formed for each terminal based on its steering vector and its channel response matrix. Multiple sets of terminals are evaluated based on their effective channel response vectors to determine the best set for uplink transmission. Each selected terminal performs spatial processing on its data symbol stream with its steering vector and transmits its spatially processed data symbol stream to an access point. The multiple selected terminals simultaneously transmit their data symbol streams via their respective MIMO channels to the access point. The access point performs receiver spatial processing to its received symbol streams. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide techniques to calibrate the downlink and uplink channels to account for differences in the frequency responses of the transmit and receive chains at an access point and a user terminal. SOLUTION: Pilots are transmitted on the downlink and uplink channels and used to derive estimates of the downlink and uplink channel responses, respectively. Two sets of correction factors are then determined based on the estimates of the downlink and uplink channel responses. A calibrated downlink channel is formed by using a first set of correction factors for the downlink channel, and a calibrated uplink channel is formed by using a second set of correction factors for the uplink channel. The first and second sets of correction factors may be determined using a matrix-ratio computation or a minimum means square error (MMSE) computation. The calibration may be performed in real-time based on over-the-air transmission. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a spatial processing method for a receiver in a MIMO system.SOLUTION: In the spatial processing method, multiple received symbol streams are obtained for multiple data symbol streams transmitted through the multiple spatial channels of a MIMO channel. Spatial processing is performed in a transmitter with steering vectors, that is, estimates of transmitter steering vectors required to orthogonalize the multiple spatial channels, and spatial processing is performed on the multiple received symbol streams with a spatial filter to obtain symbol streams for multiple filters, that is, estimates of the multiple data symbol streams. Further, in the spatial processing method, response is obtained for the spatial filter based on an MMSE criterion for minimizing a mean square error between the symbol streams for the filters and the data symbol streams.

Abstract translation: 要解决的问题：提供MIMO系统中的接收机的空间处理方法。解决方案：在空间处理方法中，通过MIMO信道的多个空间信道发送的多个数据符号流获得多个接收符号流。 在具有导向向量的发射机中执行空间处理，即，使多个空间信道正交化所需的发射机导向矢量的估计，并且对具有空间滤波器的多个接收符号流执行空间处理，以获得用于多个滤波器的符号流， 即多个数据符号流的估计。 此外，在空间处理方法中，基于用于最小化用于滤波器的符号流和数据符号流之间的均方误差的MMSE准则，获得针对空间滤波器的响应。
