## Abstract

There is disclosed a method of operating a radio node in a Radio Access Network, the method including communicating utilizing frequency resources based on allocation information received in a message, the message having an allocation information structure containing the allocation information.

## Claims

### Claim 1

A method of operating a radio node in a Radio Access Network, the method comprising:
communicating utilizing frequency resources based on allocation information in a Downlink Control Information (DCI) message, the DCI message having an allocation information structure containing the allocation information; and
the allocation information structure comprises:
a header containing a plurality of header bits indicating a first resource grouping type of a plurality of allocatable resource grouping types, the plurality of header bits being configurable to represent each of the plurality of allocatable resource grouping types, the plurality of allocatable resource grouping types comprising at least a resource element, a resource block and a resource block group; and
a bitmap containing mapping information configured to indicate a number of groupings of the first resource grouping type and map at least one resource grouping to a bandwidth, the at least one resource grouping being of the first resource grouping type.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the plurality of header bits includes M bits and the bitmap includes B bits.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the frequency resources are comprised in a bandwidth, the bandwidth being at least one of a carrier bandwidth, a system bandwidth and a user equipment bandwidth.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the frequency resources are comprised in a bandwidth, the bandwidth consisting of a number L of bandwidth elements.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the allocation information allocates frequency resources of a bandwidth to a radio node for communicating.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the allocation information pertains to frequency resources grouped in the at least one resources grouping of at least one of the plurality of allocatable resource grouping types.

### Claim 7

A method of operating an allocating radio node in a Radio Access Network, the method comprising:
transmitting a Downlink Control Information (DCI) message comprising allocation information associated with frequency resources, the DCI message having an allocation information structure containing the allocation information; and
the allocation information structure comprises:
a header containing a plurality of header bits indicating a first resource grouping type of a plurality of allocatable resource grouping types, the plurality of header bits being configurable to represent each of the plurality of allocatable resource grouping types, the plurality of allocatable resource grouping types comprising at least a resource element, a resource block and a resource block group; and
a bitmap containing mapping information configured to indicate a number of groupings of the first resource grouping type and map at least one resource grouping to a bandwidth, the at least one resource grouping being of the first resource grouping type.

### Claim 8 (depends on 7)

The method according to claim 7, wherein the plurality of header bits includes M bits and the bitmap includes B bits.

### Claim 9 (depends on 7)

The method according to claim 7, wherein the frequency resources are comprised in a bandwidth, the bandwidth being at least one of a carrier bandwidth, a system bandwidth and a user equipment bandwidth.

### Claim 10 (depends on 7)

The method according to claim 7, wherein the frequency resources are comprised in a bandwidth, the bandwidth consisting of a number L of bandwidth elements.

### Claim 11 (depends on 7)

The method according to claim 7, wherein the allocation information allocates frequency resources of a bandwidth to a radio node for communicating.

### Claim 12 (depends on 7)

The method according to claim 7, wherein the allocation information pertains to frequency resources grouped in at least one resources grouping of at least one of the plurality of allocatable resource grouping types.

### Claim 13

A radio node for a Radio Access Network, the radio node configured to:
communicate utilizing frequency resources based on allocation information in a Downlink Control Information (DCI) message, the DCI message having an allocation information structure containing the allocation information; and
the allocation information structure comprises:
a header containing a plurality of header bits indicating a first resource grouping type of a plurality of allocatable resource grouping types, the plurality of header bits being configurable to represent each of the plurality of allocatable resource grouping types, the plurality of allocatable resource grouping types comprising at least a resource element, a resource block and a resource block group; and
a bitmap containing mapping information configured to indicate a number of groupings of the first resource grouping type and map at least one resource grouping to a bandwidth, the at least one resource grouping being of the first resource grouping type.

### Claim 14

An allocating radio node for a Radio Access Network, the allocating radio node configured to:
transmit a Downlink Control Information (DCI) message comprising allocation information, the DCI message having an allocation information structure containing the allocation information; and
the allocation information structure comprises:
a header containing a plurality of header bits indicating a first resource grouping type of a plurality of allocatable resource grouping, the plurality of header bits being configurable to represent each of the plurality of allocatable resource grouping types, the plurality of allocatable resource grouping types comprising at least a resource element, a resource block and a resource block group; and
a bitmap containing mapping information configured to indicate a number of groupings of the first resource grouping type and map at least one resource grouping to a bandwidth, the at least one resource grouping being of the first resource grouping type.
