Abstract

A resource allocation method and a method for transmitting resource allocation information in a mobile communication system are disclosed. That is, a LVRB (PRB) and a DVRB which are the units of a scheduling resource are defined and a resource allocation method and a method for transmitting resource allocation information using the same are disclosed. In the LVRB, a part bitmap scheduling method using a LVRB set is suggested and a method for constructing resource allocation information using the same is suggested. In the DVRB, a method for defining the DVRB using PRBs in a subframe is suggested and a method for constructing resource allocation information using the same when scheduling is performed using the DVRB constructed by the defined method is suggested. In order to prevent interference and collision from occurring due to the complete matching of the DVRBs in respective cells, a method using different DVRBs in the respective cells is suggested.

Claims

1. A method for receiving data by a user equipment in a mobile communication system, the method comprising:

receiving, by the user equipment, control information including a first field and a second field via a control channel, the first field indicating one of N (N≧

2) resource block group (RBG) sets and the second field including a bitmap, wherein each bit of the bitmap is used to indicate whether a corresponding resource block (RB) in the indicated one of the N RBG sets is allocated or not;

interpreting the first field and the second field for resource allocation in the control information; and

receiving the data using the control information,

wherein an RBG set n (0≦

n<

N) comprises every N_th RBG starting from n_th RBG, an RBG comprises one or more consecutive RBs, and an RB comprises a plurality of consecutive subcarriers.

2. The method according to claim 1, wherein a number of RBs in each RBG depends on a total number of RBs.

3. The method according to claim 1, wherein a number of the N RBG sets is the same as a number of RBs in each RBG.

4. The method according to claim 2, wherein a number of RBs in an RBG set is the same as a total number of RBGs.

5. The method according to claim 1, wherein the RBG comprises N consecutive RBs.
