Abstract
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<NRB), and the length (L) is selected from among ‘l’ values (where l=K+nG≦NRB). 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.

A method for detecting a resource indication value (RIV) indicating a start index (S) of consecutive virtual resource blocks (VRBs) and a length (L) of the consecutive VRBs in a wireless mobile communication system, the method comprising:
- receiving downlink control information including resource block allocation information, wherein the downlink control information is common information for plural users;
- and
- detecting the resource indication value (RIV) from the resource block allocation information,
- wherein, if Y−1≦└X/2┘, the resource indication value (RIV) is denoted by RIV=X(Y−1)+Z, or else the resource indication value (RIV) is denoted by RIV=X(X−Y+1)+(X−1−Z),
- where X is denoted by X=└NVRB/G┘, Y is denoted by Y=L/G, and Z is denoted by Z=S/G, in which, L is the length of the consecutive virtual resource blocks (VRBs), S is the start index of the consecutive virtual resource blocks (VRBs), NVRB is the number of virtual resource blocks (VRBs), L is a multiple of G, S is a multiple of G, and G is a natural number that is equal to or larger than 2.
An apparatus of detecting a resource indication value (RIV) indicating a start index (S) of consecutive virtual resource blocks (VRBs) and a length (L) of the consecutive VRBs in a wireless mobile communication system, the apparatus comprising:
- a receiver configured to receive downlink control information including resource block allocation information, wherein the downlink control information is common information for plural users;
- and
- a processor configured to detect the resource indication value (RIV) from the resource block allocation information,
- wherein, if Y−1≦└X/2┘, the resource indication value (RIV) is denoted by RIV=X(Y−1)+Z, or else the resource indication value (RIV) is denoted by RIV=X(X−Y+1)+(X−1−Z),
- where X is denoted by X=└NVRB/G┘, Y is denoted by Y=L/G, and Z is denoted by Z=S/G, in which, L is the length of the consecutive virtual resource blocks (VRBs), S is the start index of the consecutive virtual resource blocks (VRBs), NVRB is the number of virtual resource blocks (VRBs), L is a multiple of G, S is a multiple of G, and G is a natural number that is equal to or larger than 2.
