    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: Techniques for use in a blind detection process of information elements. Channels can be allocated into groups. For each group, resource blocks of each channel can be further divided into subspaces. A base station may communicate a number of channels in a group, a number of subspaces allocated to a group of channels, and a bit shift value to all mobile stations via non-specific user channels to a mobile station. The mobile station uses a blind detection scheme and the number of channels allocated per group, a number of sub-spaces per group of channels, and a bit shift value to locate an information element assigned to the mobile station. A number of blind detection trials may be capped to a sum of a number of channels for all allocated groups.
