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 in a mobile communication system, the method comprising:

receiving, by a user equipment, control information including first information and second information, wherein the first information is used to indicate one of two resource allocation types and the second information includes a bitmap used to indicate resource allocation; and

receiving, by the user equipment, the data using the control information,

wherein;

for a first resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block group (RBG) in consecutive RBGs is allocated;

for a second resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block (RB) in an RBG set #n of N RBG sets is allocated, and the control information further includes third information that is used to indicate the RBG set #n of the N RBG sets;

the RBG set #n comprises every N_th RBG starting from an n_th RBG;

each RBG comprises one or more consecutive RBs;

each RB comprises a plurality of consecutive subcarriers; and

N is a number of the RBG sets.

2. A method for transmitting data in a mobile communication system, the method comprising:

transmitting, by a base station, control information including first information and second information, wherein the first information is used to indicate one of two resource allocation types and the second information includes a bitmap used to indicate resource allocation; and

transmitting, by the base station, data using the control information,

wherein;

for a first resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block group (RBG) in consecutive RBGs is allocated;

for a second resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block (RB) in an RBG set #n of N RBG sets is allocated, and the control information further includes third information that is used to indicate the RBG set #n of the N RBG sets;

the RBG set #n comprises every N_th RBG starting from an n_th RBG;

each RBG comprises one or more consecutive RBs;

each RB comprises a plurality of consecutive subcarriers; and

N is a number of the RBG sets.

3. An apparatus configured for receiving data in a mobile communication system, the apparatus comprising:

means for receiving control information including first information and second information, wherein the first information is used to indicate one of two resource allocation types and the second information includes a bitmap used to indicate resource allocation; and

means for receiving the data using the control information,

wherein;

for a first resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block group (RBG) in consecutive RBGs is allocated;

for a second resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block (RB) in an RBG set #n of N RBG sets is allocated, and the control information further includes third information that is used to indicate the RBG set #n of the N RBG sets;

the RBG set #n comprises every N_th RBG starting from an n_th RBG;

each RBG comprises one or more consecutive RBs;

each RB comprises a plurality of consecutive subcarriers; and

N is a number of the RBG sets.

4. An apparatus configured for transmitting data in a mobile communication system, the apparatus comprising:

means for transmitting control information including first information and second information, wherein the first information is used to indicate one of two resource allocation types and the second information includes a bitmap used to indicate resource allocation; and

means for transmitting data using the control information,

wherein;

for a first resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block group (RBG) in consecutive RBGs is allocated;

for a second resource allocation type of the two resource allocation types, a bit value of the bitmap indicates whether or not a corresponding resource block (RB) in an RBG set #n of N RBG sets is allocated, and the control information further includes third information that is used to indicate the RBG set #n of the N RBG sets;

the RBG set #n comprises every N_th RBG starting from an n_th RBG;

each RBG comprises one or more consecutive RBs;

each RB comprises a plurality of consecutive subcarriers; and

N is a number of the RBG sets.
