摘要： In one exemplary aspect thereof the embodiments of this invention provide an apparatus that includes a wireless receiver configurable to receive resource units; a wireless transmitter configurable to transmit feedback information to a source of the received resource units; and a channel estimator and feedback generator coupled to the wireless receiver and to the wireless transmitter. The channel estimator and feedback generator is configurable to determine a weight for each of a first resource unit and a second resource unit that are received by the receiver spaced apart at least in frequency, to determine a weight for at least some of a plurality of resource units that are intermediate at least in frequency to the first and the second resource units, and to send feedback via the transmitter. The feedback includes an indication of the determined weight for the first and the second resource units using X bits for representing each of the indications of the determined weights, and further includes an indication of weights for each of the plurality of resource units using Y bits, where Y

摘要： An exemplary embodiment in accordance with this invention is a method for determining the number of interfering streams. The method includes calculating statistical information based on one or more received OFDM signals. The number of interfering streams is estimated from the statistical information in this method. The OFDM signal(s) are received via a plurality of antennas. Storing the OFDM signal(s) in a square matrix may be included in the method. A covariance matrix of the square matrix can be determined; and a noise subspace and a signal plus interference subspace can be determined based on a SVD of the covariance matrix. The statistical information maybe based on the signal plus interference subspace. Apparatus, computer programs and computer-readable media are also discloses.

摘要： An approach for performing a random access procedure using soft-dedicated preambles is disclosed. A module designates one of a plurality of preambles, associated with one or more random access channels, as a soft-dedicated preamble. The soft-dedicated preamble is used by a user equipment that is either contention-based or non-contention-based.
