Abstract
A system to cooperatively control inter-cell interference is provided. A first frequency allocated to a central area of a serving cell associated with a serving base station may be allocated to a central area of a neighboring cell associated with a neighboring base station. A second frequency allocated to an edge area of the serving cell may be allocated to an edge area of the neighboring cell. Where a terminal is located in the edge of the neighboring cell, scheduling information, channel information, and data may be exchanged between the terminal and the serving base station.
Claims15
A system to cooperatively control inter-cell interference, comprising:
- a processor;
- a resource allocation unit to allocate a first frequency to a central area of a neighboring cell associated with a neighboring base station, and to allocate a second frequency to an edge area of the neighboring cell, wherein the first frequency is allocated to a central area of a serving cell associated with a serving base station, and the second frequency is allocated to an edge area of the serving cell;
- and
- an interference controller configured:
- to control a least one of scheduling information, channel information, and data to be transmitted and be received between a terminal and the serving base station using the second frequency, where the terminal is located in the edge area of the neighboring cell,
- to allocate the first frequency equally between the serving base station and the neighboring base station in a first interval, and to allocate the second frequency and a third frequency orthogonally between the serving base station and the neighboring base station during a second interval.
A method of cooperatively controlling inter-cell interference between multiple cells, comprising:
- allocating a first frequency to a central area of a neighboring cell associated with a neighboring base station, wherein the first frequency is allocated to a central area of a serving cell associated with a serving base station;
- allocating a second frequency to an edge area of the neighboring cell, wherein the second frequency is allocated to an edge area of the serving cell;
- controlling, by a processor, interference between the serving cell and the neighboring cell by exchanging at least one of scheduling information, channel information, and data between a terminal and the serving base station using the second frequency, where a terminal is located in the edge area of the neighboring cell;
- allocating the first frequency equally between the serving base station and the neighboring base station in a first interval;
- and
- allocating the second frequency and a third frequency orthogonally between the serving base station and the neighboring base station during a second interval.
A non-transitory computer-readable storage medium storing a program to cooperatively control inter-cell interference between multiple cells, comprising instructions to cause a computer to:
- allocate a first frequency to a central area of a neighboring cell associated with a neighboring base station, wherein the first frequency is allocated to a central area of a serving cell associated with a serving base station;
- allocate a second frequency to an edge area of the neighboring cell, wherein the second frequency is allocated to an edge area of the serving cell;
- and
- control interference between the serving cell and the neighboring cell by exchanging at least one of scheduling information, channel information, and data between a terminal and the serving base station using the second frequency, where a terminal is located in the edge area of the neighboring cell, wherein the first frequency is allocated equally between the serving base station and the neighboring base station in a first interval, and the second frequency and a third frequency are allocated orthogonally between the serving base station and the neighboring base station during a second interval.
