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 user equipment, a control channel signal including first information and second information via a control channel, the first information indicating one of N resource block (RB) sets, and the second information including a bitmap indicating whether or not a corresponding RB is allocated in the indicated RB set; and

receiving, by the user equipment, the data using one or more RBs allocated by the control channel signal,

wherein;

the indicated RB set comprises a plurality of resource block groups (RBGs) in which neighboring RBGs are not consecutive in a frequency region;

a size of an RBG is N consecutive RBs; and

N is an integer equal to or greater than 2.

2. The method according to claim 1, wherein the indicated RB set comprises every Nth RBG starting from a predetermined RBG.

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

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

5. The method according to claim 1, wherein a number of RBs in an RB set is the same as a total number of RBGs.

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

constructing, by a base station, a control channel signal including first information and second information via a control channel, the first information indicating one of N resource block (RB) sets, and the second information including a bitmap indicating whether or not a corresponding RB is allocated in the indicated RB set; and

transmitting, by the base station, the control channel signal via the control channel; and

transmitting, by the base station, the data corresponding to the control channel,

wherein;

the indicated RB set comprises a plurality of resource block groups (RBGs) in which neighboring RBGs are not consecutive in a frequency region;

a size of an RBG is N consecutive RBs; and

N is an integer equal to or greater than 2.

7. The method according to claim 6, wherein the indicated RB set comprises every Nth RBG starting from a predetermined RBG.

8. The method according to claim 6, wherein a number of RBs in each RBG depends on a total number of RBs in a subframe.

9. The method according to claim 6, wherein a number of the RB sets is the same as a number of RBs in each RBG.

10. The method according to claim 6, wherein a number of RBs in an RB set is the same as a total number of RBGs.

11. A user equipment (UE) for use in a mobile communication system, the UE comprising:

a receiver; and

a controller configured to control the receiver and cause the receiver to;

receive a control channel signal including first information and second information via a

control channel, the first information indicating one of N resource block (RB) sets, and the second information including a bitmap indicating whether or not a corresponding RB is allocated in the indicated RB set; and

receive data using the control channel signal,

wherein;

the indicated RB set comprises a plurality of resource block groups (RBGs) in which neighboring RBGs are not consecutive in a frequency region;

a size of an RBG is N consecutive RBs; and

N is an integer equal to or greater than 2.

12. The UE according to claim 11, wherein the indicated RB set comprises every Nth RBG starting from a predetermined RBG.

13. The UE according to claim 11, wherein a number of RBs in each RBG depends on a total number of RBs in a subframe.

14. The UE according to claim 11, wherein a number of the RB sets is the same as a number of RBs in each RBG.

15. The UE according to claim 11, wherein a number of RBs in an RB set is the same as a total number of RBGs.

16. A base station (BS) for use in a mobile communication system, the BS comprising:

a transmitter; and

a controller configured to;

control the transmitter;

construct a control channel signal including first information and second information via a control channel, the first information indicating one of N resource block (RB) sets, and the second information including a bitmap indicating whether or not a corresponding RB is allocated in the indicated RB set;

cause the transmitter to transmit the control channel signal via the control channel; and

cause the transmitter to transmit data corresponding to the control channel,

wherein;

the indicated RB set comprises a plurality of RBGs in which neighboring RBGs are not consecutive in a frequency region;

a size of RBG is N consecutive RBs; and

N is an integer equal to or greater than 2.

17. The BS according to claim 16, wherein the indicated RB set comprises every

Nth RBG starting from a predetermined RBG.

18. The BS according to claim 16, wherein a number of RBs in each RBG depends on a total number of RBs in a subframe.

19. The BS according to claim 16, wherein a number of the RB sets is the same as a number of RBs in each RBG.

20. The BS according to claim 16, wherein a number of RBs in an RB set is the same as a total number of RBGs.
