Abstract
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.
