Method for signaling of resource allocation to adjust granularity in cellular multi-carrier system
A method for adjusting a granularity of resource allocation in a wireless mobile communication system supporting a compact scheduling is discussed. A resource indication value (RIV) corresponds to a start index (S) of one set of consecutive virtual resource blocks (VRBs) and a length of the VRBs. The start index (S) is selected from among ‘s’ values (where s−P+mT<N RB ), and the length (L) is selected from among ‘l’ values (where l=K+nG≦N RB ). Here, P is a predetermined integer of 0 or higher, T or G is a predetermined natural number, m is an integer of 0 or higher, and n is a natural number.
