Abstract:
1. A method for receiving downlink data using resource blocks at a user equipment in a wireless mobile communication system, the method comprising: receiving downlink control information including resource allocation information for the downlink data from a base station; and receiving the downlink data mapped to physical resource blocks (PRBs) based on the downlink control information, wherein: the resource allocation information indicates virtual resource block (VRB) allocations for the user equipment; indexes of PRBs to which the downlink data are mapped are determined based on mapping relationship between VRBs and the PRBs; the mapping relationship is defined such that indexes of the VRBs are mapped to indexes of the PRBs for a first part and a second part of a subframe and the indexes of the PRBs for the second part are separated with respect to the indexes of the PRBs for the first part based on a predetermined gap; an index of one of the PRBs on each part that is mapped to an index of one or the VRBs is determined based on the predetermined gap and a number of the VRBs.
