摘要： In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ration transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.

摘要： Embodiments of an OFDM transmitter and method of reducing the effects of interference on subcarriers in an OFDM system by symbol loading are disclosed herein. A linear transformation is performed on a group of two or more input data symbols that are mapped to different signal dimensions to generate a corresponding two or more output data symbols. Each of the output data symbols has an increased number of constellation points. Each output data symbol is configured for transmission within one of the different signal dimensions. The linear transformation is configured so that each of the two or more output data symbols carry the information of each of the input data symbols of the group. This coding together of input data symbols that are mapped to different signal dimensions may provide improved reliability against fading and severe interference. The different signal dimensions may comprise a frequency, a time and/or a space dimension.

摘要： Embodiments of a communication station and methods for efficiently providing channel feedback for MIMO communications over an OFDM channel are generally described herein. In some embodiments, receiving stations may perform a recursive differential quantization of channel information across time and/or frequency to generate quantized differential channel feedback. The quantized differential channel feedback from each receiving station may be used by a transmitting station to precode MIMO transmissions to one or more of the receiving stations. The quantized differential channel feedback may be either a quantized differential channel matrix or a quantized differential beamforming matrix.

摘要： A method for performing measurement by a radio apparatus is presented. In one embodiment, the method includes determining raw measurements (e.g., a channel estimation and a noise variance estimation) of a subband and determining a rank indicator (RI) without requiring a precoding matrix indicator (PMI) search. The method includes calculating, based at least on the raw measurements, a mean instantaneous capacity (MIC) for the subband and determining a channel quality indicator (CQI) and a PMI based at least on the MIC. In one embodiment, the method uses subband-based measurements for performing feedback/measurement.

摘要： A mobile station (MS) to determine signal quality values is disclosed. The MS may include a transmitter and a receiver and the receiver may determine a signal power value, a noise power value, and an interference power value of a signal received from antennas. The receiver may determine the signal power value and the interference value using a second preamble included in a super-frame of the signal, wherein the second preamble includes cell information. The receiver may determine a noise power value of the signal received from the plurality of antennas using unoccupied orthogonal frequency division multiple access (OFDMA) tones of a first preamble included in the super-frame of the signal, wherein the first preamble includes carrier information. The receiver may also use the fractional frequency reuse (FFR) and MIMO features to determine signal quality values using the signal power value, the noise power value, and the interference power value.
