Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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.
