Abstract

According to one embodiment, a user equipment for use in a mobile communication system is configured to: receive 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; interpret the first field and the second field for resource allocation in the control information; and receive data using the control information. An RBG set n (0≦n<N) includes every N_th RBG starting from n_th RBG, an RBG includes one or more consecutive RBs, and an RB includes a plurality of consecutive subcarriers.

Claims

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

receiving, by a wireless apparatus, control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation; and

receiving, by the wireless apparatus, 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 a corresponding resource block group (RBG) is allocated or not in consecutive RBGs;

for a second resource allocation type of the two resource allocation types, third information in the control information indicates one of N RB sets, and a bit value of the bitmap indicates whether a corresponding resource block (RB) is allocated or not in the indicated RB set;

the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N−

1 RBG(s);

a size of RBG is N consecutive RBs;

a size of RB is a predetermined number of consecutive subcarriers; and

N is an integer equal to or greater than 2.

2. The method of claim 1, wherein the indicated RB set comprises every N_th RBG starting from a predetermined RBG.

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

transmitting, by a wireless apparatus, control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation; and

transmitting, by the wireless apparatus, 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 a corresponding resource block group (RBG) is allocated or not in consecutive RBGs;

for a second resource allocation type of the two resource allocation types, third information in the control information indicates one of N RB sets, and a bit value of the bitmap indicates whether a corresponding resource block (RB) is allocated or not in the indicated RB set;

the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N−

1 RBG(s);

a size of RBG is N consecutive RBs;

a size of RB is a predetermined number of consecutive subcarriers; and

N is an integer equal to or greater than 2.

4. The method of claim 3, wherein the indicated RB set comprises every N_th RBG starting from a predetermined RBG.

5. A wireless apparatus configured for receiving data in a mobile communication system, the wireless apparatus comprising:

a receiver for;

receiving control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation; and

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 a corresponding resource block group (RBG) is allocated or not in consecutive RBGs;

for a second resource allocation type of the two resource allocation types, third information in the control information indicates one of N RB sets, and a bit value of the bitmap indicates whether a corresponding resource block (RB) is allocated or not in the indicated RB set;

the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N−

1 RBG(s);

a size of RBG is N consecutive RBs;

a size of RB is a predetermined number of consecutive subcarriers; and

N is an integer equal to or greater than 2.

6. The wireless apparatus of claim 5, wherein the indicated RB set comprises every N_th RBG starting from a predetermined RBG.

7. A wireless apparatus configured for transmitting data in a mobile communication system, the apparatus comprising:

a transmitter for;

transmitting control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation; and

transmitting 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 a corresponding resource block group (RBG) is allocated or not in consecutive RBGs;

for a second resource allocation type of the two resource allocation types, third information in the control information indicates one of N RB sets, and a bit value of the bitmap indicates whether a corresponding resource block (RB) is allocated or not in the indicated RB set;

the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N−

1 RBG(s);

a size of RBG is N consecutive RBs;

a size of RB is a predetermined number of consecutive subcarriers; and

N is an integer equal to or greater than 2.

8. The wireless apparatus of claim 7, wherein the indicated RB set comprises every N_th RBG starting from a predetermined RBG.
