Abstract

Provided are a method of allocating a resource in a wireless communication system and an apparatus using the method. The method includes: measuring a variation of a data usage pattern or density of user equipments located in a region for providing a service; determining whether the variation is greater than or equal to a threshold; and determining a resource allocation type of the region for providing the service on the basis of the determination result.

Claims

1. A method of allocating a resource in a wireless communication system, the method comprising:

measuring a variation of a data usage pattern or density of user equipments located in a region for providing a service;

determining whether the variation is greater than or equal to a threshold; and

determining a resource allocation type of the region for providing the service on the basis of the determination result,

wherein the resource allocation type is a type in which a base station included in the region for providing the service allocates the resource to the user equipments, and

wherein the determining of the resource allocation type comprises;

calculating a required data pattern of the user equipments on the basis of an average value of data usage patterns of the respective user equipments located in the region for providing the service; and

determining by the base station a ratio of a carrier to be allocated to each of the user equipments among available carriers on the basis of the required data pattern.

2. The method of claim 1, wherein the determining of the resource allocation type further comprises:

calculating a required data pattern of the user equipments on the basis of an average value of data usage patterns of the respective user equipments located in the region for providing the service; and

determining a ratio of an almost blank subframe (ABS) not including a data channel among subframes included in a frame on the basis of the required data pattern.

3. The method of claim 1, wherein a data provision pattern based on the resource allocation type is determined on the basis of the data usage pattern or density of the user equipments located in the region for providing the service.

4. An apparatus comprising:

a radio frequency (RF) unit for transmitting or receiving a radio signal; and

a processor operatively coupled to the RF unit,

wherein the processor is configured to;

measure a variation of a data usage pattern or density of user equipments located in a region for providing a service;

determine whether the variation is greater than or equal to a threshold; and

determine a resource allocation type of the region for providing the service on the basis of the determination result,

wherein the resource allocation type is a type in which a base station included in the region for providing the service allocates the resource to the user equipments, and

wherein the determining of the resource allocation type comprises;

calculating a required data pattern of the user equipments on the basis of an average value of data usage patterns of the respective user equipments located in the region for providing the service; and

determining by the base station a ratio of a carrier to be allocated to each of the user equipments among available carriers on the basis of the required data pattern.

5. The apparatus of claim 4, wherein the determining of the resource allocation type further comprises:

calculating a required data pattern of the user equipments on the basis of an average value of data usage patterns of the respective user equipments located in the region for providing the service; and

determining a ratio of an almost blank subframe (ABS) not including a data channel among subframes included in a frame on the basis of the required data pattern.

6. The apparatus of claim 4, wherein a data provision pattern based on the resource allocation type is determined on the basis of the data usage pattern or density of the user equipments located in the region for providing the service.
