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.
