Abstract
A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE receives downlink control information including resource allocation information and downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the UE. Indexes of the PRBs to which the downlink data are mapped are determined based on a mapping relationship between virtual resource blocks (VRBs) and the PRBs. The mapping relationship is defined based on indexes of the VRBs which are mapped to the indexes of the PRBs for a first slot of a subframe and a second slot of the subframe. The indexes of the PRBs for the second slot are shifted with respect to the indexes of the PRBs for the first slot based on a predetermined gap. The mapping relationship includes a transformation of VRB indexes based on a matrix.
