## 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 Nth RBG starting from nth RBG, an RBG includes one or more consecutive RBs, and an RB includes a plurality of consecutive subcarriers.

## Claims

### Claim 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 Nth RBG starting from nth RBG, an RBG comprises one or more consecutive RBs, and an RB comprises a plurality of consecutive subcarriers.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 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 Nth RBG starting from nth RBG, an RBG comprises one or more consecutive RBs, and an RB comprises a plurality of consecutive subcarriers.

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 6)

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

### Claim 9 (depends on 6)

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

### Claim 10 (depends on 6)

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

### Claim 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 Nth RBG starting from nth RBG, an RBG comprises one or more consecutive RBs, and an RB comprises a plurality of consecutive subcarriers.

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 11)

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.

### Claim 14 (depends on 11)

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

### Claim 15 (depends on 11)

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