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.

Claims

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.
