Abstract

A resource allocation method according to the present invention may comprise the steps of: allocating a signal of an external resource to a predetermined resource according to a preconfigured resource allocation frame structure by a first base station governing a first cell; allocating a signal of an internal resource to the resource according to the resource allocation frame structure by a second base station governing a second cell adjacent to the first cell; and frequency-hopping the signal of the internal resource by the second base station when the signal of the internal resource overlaps the signal of the external resource. Accordingly, proposed is a resource allocation method capable of stably receiving a signal even when a terminal moving in a dense small cell structure is located at a cell edge, that is, an inter-cell boundary area.

First claim

What is claimed is:

1. A resource allocation method comprising:
allocating, by a first base station operating in a first cell, a first signal of an outer resource of the first cell to a resource based on a resource allocation frame structure for a terminal, the first signal having a first beam width;
allocating, by a second base station operating in a second cell adjacent to the first cell, a second signal of an outer resource of the second cell to the resource for the terminal, the second signal having a second beam width which is different from the first beam width;
wherein the first signal has a first priority, and the second signal has a second priority different from the first priority, and
wherein the first priority is higher than the second priority, and the first beam width is greater than the second beam width;
allocating, by a third base station operating in a third cell adjacent to the first cell and the second cell, a third signal of an inner resource of the third cell to the resource for the terminal; and
performing, by the third base station, frequency hopping on the third signal of the inner resource of the third cell to change the terminal allocated to the resource to a different terminal when the third signal of the inner resource overlaps with the second signal of the outer resource of the second cell.

2. The resource allocation method of claim 1 , wherein transmit power of the first signal is higher than transmit power of the second signal.

3. The resource allocation method of claim 1 ,
wherein the third signal allocated to the inner resource comprises signals having a plurality of priorities, and
wherein the frequency hopping is performed on a signal having a low priority among the signals allocated to the inner resource.

4. The resource allocation method of claim 1 , wherein the first base station and the second base station allocate more resources to the first signal having the first priority than to the second signal having the second priority.
