Abstract

[Object] To improve communication of a communication node that utilizes a radio resource (frequency channel) under an environment in which there is an interference from communication involving a communication node that is not control target, with less calculation amount.
[Solution] Provided is a communication control device including: an acquisition unit configured to acquire first interference information indicating a first interference from communication involving a communication node that is not control target and second interference information indicating a second interference from communication involving another communication node of control target, with respect to each of communication nodes of control target; and a classifying unit configured to classify the communication nodes into groups related to a decision of a radio resource that a communication node is able to utilize, on the basis of the first interference information and the second interference information with respect to the communication nodes.

First claim

1 . A communication control device comprising:
an acquisition unit configured to acquire first interference information indicating a first interference from communication involving a communication node that is not control target and second interference information indicating a second interference from communication involving another communication node of control target, with respect to each of a plurality of communication nodes of control target; and a classifying unit configured to classify the plurality of communication nodes into a plurality of groups related to a decision of a radio resource that a communication node is able to utilize, on the basis of the first interference information and the second interference information with respect to the plurality of communication nodes.

2 . The communication control device according to claim 1 , wherein
the plurality of groups are a plurality of groups corresponding to an order in which the radio resource is decided.

3 . The communication control device according to claim 2 , wherein
the plurality of groups include at least a first group and a second group, and a communication node classified into the first group is a communication node in which a level of the first interference relative to the second interference is larger, as compared with a communication node classified into the second group.

4 . The communication control device according to claim 3 , wherein
the second group is a group for which the radio resource is decided after the first group.

5 . The communication control device according to claim 4 , further comprising:
a deciding unit configured to decide the radio resource with respect to each of the plurality of communication nodes, wherein the deciding unit decides the radio resource with respect to each of one or more communication nodes classified into the first group, and decides the radio resource with respect to each of one or more communication nodes classified into the second group, on the basis of a decision result of the radio resource in the first group.

6 . The communication control device according to claim 5 , wherein
the deciding unit decides one or more radio resource candidates having a smaller level of the first interference among two or more radio resource candidates, as the radio resource for the communication node classified into the first group.

7 . The communication control device according to claim 3 , wherein
the second group is a group for which the radio resource is decided before the first group.

8 . The communication control device according to claim 7 , further comprising:
a deciding unit configured to decide the radio resource with respect to each of the plurality of communication nodes, wherein the deciding unit decides the radio resource with respect to each of one or more communication nodes classified into the second group, and decides the radio resource with respect to each of one or more communication nodes classified into the first group, on the basis of a decision result of the radio resource in the second group.

9 . The communication control device according to claim 8 , wherein
the deciding unit decides one or more radio resource candidates having a smaller level of a third interference with the one or more communication nodes classified into the second group among two or more radio resource candidates, as the radio resource for the communication node classified into the first group.

10 . The communication control device according to claim 3 , further comprising:
a deciding unit configured to decide the radio resource with respect to each of the plurality of communication nodes, wherein, when deciding the radio resource with respect to each of the one or more communication nodes classified into the second group, the deciding unit decides the radio resource with respect to the communication node having a smaller level of the second interference, and decides, on the basis of a decision result of the radio resource with respect to the communication node, the radio resource with respect to the communication node having a larger level of the second interference.

11 . The communication control device according to claim 3 , further comprising:
a deciding unit configured to decide the radio resource with respect to each of the plurality of communication nodes, wherein the deciding unit decides one or more radio resource candidates having a smaller level of interference including the first interference and the second interference among two or more radio resource candidates, as the radio resource for the communication node classified into the second group.

12 . The communication control device according to claim 3 , wherein
the first interference information indicates the first interference in each of two or more radio resource candidates, the second interference information indicates the second interference in each of the two or more radio resource candidates, and the level of the first interference relative to the second interference corresponds to the number of the radio resource candidates for which a level of the first interference is larger than a level of the second interference by a predetermined threshold value or more.

13 . The communication control device according to claim 1 , further comprising:
a deciding unit configured to decide the radio resource with respect to each of the plurality of communication nodes, wherein the plurality of communication nodes are communication nodes of a higher priority than one or more low priority communication nodes of control target, and the deciding unit further decides the radio resource with respect to each of the one or more low priority communication nodes, on the basis of a decision result of the radio resource with respect to the plurality of communication nodes.

14 . The communication control device according to claim 13 , further comprising:
a determination unit configured to determine whether a predetermined condition for a fourth interference with communication involving the plurality of communication nodes is satisfied, with respect to each of the one or more low priority communication nodes, wherein the deciding unit decides the radio resource with respect to each of the one or more low priority communication nodes, on the basis of a determination result with respect to the predetermined condition.

15 . The communication control device according to claim 1 , wherein
the first interference is an interference by a downlink signal transmitted by the communication node that is not control target or an uplink signal transmitted to the communication node that is not control target, and the second interference is an interference by a downlink signal transmitted by the other communication node or an uplink signal transmitted to the other communication node.

16 . The communication control device according to claim 15 , wherein
the interference by the uplink signal transmitted to the other communication node is an interference estimated under an assumption that a transmission node that transmits the uplink signal to the other communication node exists in a predetermined range or at a predetermined position which are closer to the communication node of control target within a communication range of the other communication node.

17 . The communication control device according to claim 1 , wherein
the communication node that is not control target includes a communication node of a primary system, and each of the plurality of communication nodes is a communication node of a secon
