Abstract

A radio communication node receives resource information indicating a type of resources allocated to a radio link with a lower node from a network and establishes the radio link based on the resource information. The type of resources includes a specific type that can designate availability of a frequency resource in a frequency direction. When the frequency resource is the specific type, the radio communication node can receive the resource information indicating the availability of the frequency resource.

Claims (22)

1 . A radio communication node, comprising:

a receiver configured to receive Downlink Control Information including resource information indicating availability of a soft resource allocated to a radio link with a lower node from a network; and

a processor configured to establish the radio link based on the resource information,

wherein the soft resource can designate availability of a resource block in a frequency direction; and

the processor determines whether all resources blocks are available or not as the soft resource when the soft resource is indicated as available.

2 . The radio communication node according to claim 1 , wherein the processor uses the resource block only when transmission to and reception from a higher node is not executed.

3 . A radio communication node, comprising:

a receiver configured to receive Downlink Control Information including resource information indicating availability of a soft resource allocated to a radio link with a lower node from a network; and

a processor configured to establish the radio link based on the resource information,

wherein the soft resource can designate availability of a resource block in a frequency direction; and

the processor determines whether or not a group of resources blocks is available as the soft resource when the soft resource is indicated as available.

4 . The radio communication node according to claim 3 , wherein the processor uses the resource block only when transmission to and reception from a higher node is not executed.

5 . A radio communication method comprising the steps of:

receiving Downlink Control Information including resource information indicating availability of a soft resource allocated to a radio link with a lower node from a network; and

establishing the radio link based on the resource information,

wherein the soft resource can designate availability of a resource block in a frequency direction; and

in the establishing step, whether all resources blocks are available or not as the soft resource is determined when the soft resource is indicated as available.

6 . A radio communication method comprising the steps of:

receiving Downlink Control Information including resource information indicating availability of a soft resource allocated to a radio link with a lower node from a network; and

establishing the radio link based on the resource information,

wherein the soft resource can designate availability of a resource block in a frequency direction; and

in the establishing step, whether or not a group of resources blocks is available as the soft resource is determined when the soft resource is indicated as available.
