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 user equipment for use in a mobile communication system, the user equipment comprising:

a receiver; and

a controller,

wherein the receiver 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;

wherein the controller is configured to interpret the first field and the second field for resource allocation in the control information;

wherein the receiver is further configured to receive data using the control information; and

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 user equipment of claim 1, wherein a number of RBs in each RBG depends on a total number of RBs.

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

4. The user equipment of claim 1, wherein a number of RBs in an RBG set is the same as a total number of RBGs.

5. The user equipment of claim 1, wherein the RBG comprises N consecutive RBs.

6. A method for transmitting data by a base station in a mobile communication system, the method comprising:

transmitting 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; and

transmitting 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.

7. The method of claim 6, wherein a number of RBs in each RBG depends on a total number of RBs.

8. The method of claim 6, wherein a number of the N RBG sets is the same as a number of RBs in each RBG.

9. The method of claim 6, wherein a number of RBs in an RBG set is the same as a total number of RBGs.

10. The method of claim 6, wherein the RBG comprises N consecutive RBs.

11. A base station for use in a mobile communication system, the base station comprising:

a transmitter configured to;

transmit 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; and

transmit 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.

12. The base station of claim 11, wherein a number of RBs in each RBG depends on a total number of RBs.

13. The base station of claim 11, wherein a number of the N RBG sets is the same as a number of RBs in each RBG.

14. The base station of claim 11, wherein a number of RBs in an RBG set is the same as a total number of RBGs.

15. The base station of claim 11, wherein the RBG comprises N consecutive RBs.
