Abstract

This invention is directed to provision of a technique for dynamically performing a priority band establishment that can achieve the suppression of interference between adjacent cells. This invention is characterized in that: a base-point resource block, which serves as a base point in establishing a priority resource block to be used, on a priority basis, by a terminal for which the quality of a communication path does not meet a predetermined quality, is so decided as to be different from the base-point resource block of an adjacent communication area; and the priority resource block is established, based on a communication load, in a predetermined order with the decided base-point resource block used as the base point.

Claims

1. A setting apparatus comprising:

a determining section for determining a base-point resource block serving as a base point in setting a priority resource block to be preferentially used by a terminal whose communication path quality does not satisfy a predetermined quality, said base-point resource block being determined differently from that for an adjacent communication area; and

a setting section for setting said priority resource block in a predetermined sequence from said determined base-point resource block serving as a base point based on a communication load.

2. The setting apparatus according to claim 1, wherein said predetermined sequence is an order of an identification number for uniquely identifying a resource block.

3. The setting apparatus according to claim 1, wherein said predetermined sequence is an order of an identification number for uniquely identifying a resource block, and wherein the order is arranged alternately and adjacently before and after said base-point resource block.

4. The setting apparatus according to claim 1, wherein said predetermined sequence is an order of an identification number for uniquely identifying a resource block, and wherein a descending order and an ascending order are different between said adjacent communication area and an own communication area.

5. The setting apparatus according to claim 1, wherein said communication load is a communication load on an own communication area.

6. The setting apparatus according to claim 1, wherein said communication load is a communication load on communication areas other than an own communication area.

7. A communications system comprising:

a determining section for determining a base-point resource block serving as a base point in setting a priority resource block to be preferentially used by a terminal whose communication path quality does not satisfy a predetermined quality, said base-point resource block being determined differently from that for an adjacent communication area; and

a setting section for setting said priority resource block in a predetermined sequence from said determined base-point resource block serving as a base point based on a communication load.

8. A base station comprising:

a determining section for determining a base-point resource block serving as a base point in setting a priority resource block to be preferentially used by a terminal whose communication path quality does not satisfy a predetermined quality, said base-point resource block being determined differently from that for an adjacent communication area; and

a setting section for setting said priority resource block in a predetermined sequence from said determined base-point resource block serving as a base point based on a communication load.

9. A setting method comprising:

a determining step of determining a base-point resource block serving as a base point in setting a priority resource block to be preferentially used by a terminal whose communication path quality does not satisfy a predetermined quality, said base-point resource block being determined differently from that for an adjacent communication area; and

a setting step of setting said priority resource block in a predetermined sequence from said determined base-point resource block serving as a base point based on a communication load.

10. A program for a setting apparatus, said program being stored on a non-transitory computer readable medium, the program causing said setting apparatus to execute:

determining processing of determining a base-point resource block serving as a base point in setting a priority resource block to be preferentially used by a terminal whose communication path quality does not satisfy a predetermined quality, said base-point resource block being determined differently from that for an adjacent communication area; and

setting processing of setting said priority resource block in a predetermined sequence from said determined base-point resource block serving as a base point based on a communication load.
