Abstract: PROBLEM TO BE SOLVED: To provide a rate combination with a highest overall throughput and a non-negative total SNR (Signal Noise Ratio) margin.
SOLUTION: For rate selection with margin sharing in a system with a vector-quantized rate set, SNR estimates are obtained for usable transmission channels. The total SNR margin is determined for each rate combination based on the SNR estimates for the transmission channels. Each rate combination is associated with a specific number of data streams to transmit, a rate for each data stream and an efficient overall throughput.

Abstract: PROBLEM TO BE SOLVED: To provide calibration of downlink and uplink to account for differences in the responses of transmit and receive chains at an access point and a user terminal. SOLUTION: For initial calibration, the access point and user terminal transmit MIMO pilots, which are used to derive channel estimates including the responses of the applicable transmit/receive chains, on the downlink and uplink. Correction matrices are derived based on these channel estimates, and thereafter they are used by the access point and user terminal, respectively. For follow-on calibration, one entity transmits the MIMO pilot and a steered reference. The other entity derives a first transmit matrix based on the steered reference, and a second transmit matrix based on the MIMO pilot and calibration error matrices which contain estimates of the errors. The calibration error matrices may be iteratively adjusted based on an adaptive procedure to minimize the errors between the two transmit matrices. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To much more increase the efficiency of data sending in a multi-antenna communication system utilizing orthogonal frequency division multiplexing (OFDM). SOLUTION: A sending entity uses a different steering vector for a different sub-band in order to accomplish a steering diversity. Each steering vector demarcates, in short, forms beams for a pertinent sub-band. An arbitrary steering vector may be used for the steering diversity. The steering vector may be demarcated so as to change consecutively in place of an abrupt change in the entire sub-band. This may be accomplished by applying a consecutively changing phase shift ranging over the entire sub-band for each sending antenna. As one example, the phase shift may change ranging over the entire sub-band for each sending antenna, and each antenna may be correlated with a different phase slope. When the phase shift changing linearly is applied to a modulation symbol in a frequency area, the application may be accomplished by either retarding a corresponding time area sample, or circularly shifting it.

Abstract: PROBLEM TO BE SOLVED: To provide a method for partitioning and allocating available system resources among cells in a wireless communication system and for allocating resources in each cell for data transmission via an uplink to terminals.
SOLUTION: A first set of parameters including interference characterization of each cell to be used to schedule terminals for data transmission is received, a priority is given to the terminals to be considered for scheduling, and at least a portion thereof, that is, one or more terminals are scheduled for data transmission on the basis of the priority of the terminals. A channel is allocated to each scheduled terminal based on the priority or load requirements of the terminal. A second set of parameters to be used to control transmission by the scheduled terminal is updated, and one transmission or more is received from the one scheduled terminal or more on the allocated channel.

Abstract: PROBLEM TO BE SOLVED: To generate steering matrices for pseudo-random transmit steering (PRTS) to be used for spatial processing. SOLUTION: The steering matrices can be generated by selecting a base matrix which can be a Walsh matrix or a Fourier matrix. Different combinations of scalars are then selected, with each combination including at least one scalar for at least one row of the base matrix. Each scalar is a real or complex value (e.g., +1,-1,+j or -j). Different steering matrices are generated by multiplying the base matrix by each of the different combinations of scalars. The steering matrices are different permutations of the base matrix. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide techniques for performing open-loop rate control in a TDD communication system. SOLUTION: In the open-loop rate control, the channel quality of a first link (B, A) is estimated based on a transmission received via the first link (B, A). The channel quality of a second link (A, B) is estimated based on the estimated channel quality of the first link (B, A) and an asymmetric parameter. A sub-band for a data transmission via the second link (A, B) is selected based on the estimated channel quality of the second link (A, B). The estimated channel quality for each link may be given by a set of SNR estimates for a set of transmission channels on that link. The asymmetric parameter may be determined based on (1) the capabilities (e.g., transmission power, receiver noise figure, and number of antennas) of the transmitting and receiving stations or (2) received SNRs for the first link (B, A) and second link (A, B).
