摘要： A system for using a predetermined sequence of transmission modes together with power sequencing in order to reduce signaling while improving SNIR levels. Each sequence comprises a vector of transmission modes, where each mode can include a signal constellation, a concatenated channel coding type and rate and, for multiple-input multiple-output systems, one type of matrix modulation. Base transceiver stations can estimate the interference condition for each piece of user equipment and, based on this information, will preferably decide an optimal sequence for each item of user equipment.

摘要： A method for facilitating broadband multi-carrier wireless transmission, whereby a plurality of transmit antennas are divided into two or more transmit antenna groups of transmit antennas so that the correlation between antennas in each group is minimized, and each group of antennas transmits on a predetermined frequency with a different time periodicity, and each transmit antenna in each group transmits training sequences which are reciprocally time-orthogonal. Each of a plurality of receive antennas receives signals from each transmit antenna group. The signals from each group are separated via a band-pass filter, and a maximum estimation range of a frequency offset estimation algorithm is determined by the group having the shortest time period, and the accuracy of the frequency offset estimation algorithm is determined by the group having the longest time period. The received signal is corrected with the frequency offset.

摘要： A multiple-user multiple input-multiple output wireless communication system uses a set of multiple subcarriers arranged in plural subsets or resource blocks. Precoding of signals transmitted from a base station to user terminals involves acquiring channel state information on the connection channel between the base station and user terminals in the plurality. Channel quality indicators are detected with user terminals for respective subsets of resource blocks to produce user/resource block pairs having associated channel quality indicators. The user/resource block pairs are subjected to selection as a function of the channel quality indicators associated therewith so that precoding is performed by acquiring channel state information exclusively for the user/resource block pairs surviving the selection as a function of the channel quality indicators and, possibly, other selection steps as a function of other parameters, such as, speed, maximum bit rate, and direction of arrival or angular spread in a multiple-stage selection process.

摘要： A method is provided for selecting a precoding matrix to be used in an MIMO communication system. The MIMO communication system includes a transmitter, a receiver and a communication channel. The precoding matrix is used by the transmitter to precode codewords to be transmitted to the receiver over the communication channel. At the receiver, an optimum precoding matrix within a codebook of precoding matrices is determined based on a metric related to the power of received signal layers. An indication is then fed back from the receiver to the transmitter to enable the transmitter to select the optimum precoding matrix from the codebook.
