Abstract

A communication method and a system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT) are provided. The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for allocating resources and a method of a base station is provided. The method includes receiving from a terminal a resource allocation request, receiving from the terminal a control message including location information of a zone where the terminal is located, and allocating a resource group based on the location information.

Claims

1. A method of a base station, the method comprising:

transmitting system information including information on resource groups;

receiving, from a terminal, a resource allocation request;

receiving, from the terminal, a control message including location information of a first zone where the terminal is located; and

allocating at least one resource group among the resource groups based on the location information,

wherein a number of the at least one resource group allocated to the terminal is determined based on a number of terminals in a connected state and a number of terminals in an idle state which are located in the first zone.

2. The method of claim 1, wherein the allocating comprises:

receiving situation information associated with the terminal; and

allocating the at least one resource group, which is different from a resource group allocated to a second zone adjacent to the first zone, among the resource groups, to the terminal based on the location information and the situation information,

wherein the situation information includes at least one of information on a number of terminals located in the first zone or a size of the first zone.

3. The method of claim 2, wherein a reception period of the location information is determined based on the situation information, and

wherein messages are transmitted on the at least one allocated resource group using a different transmission power according to a type of each of the messages.

4. The method of claim 1, wherein the allocating comprises:

allocating at least two resource groups, in case that a number of terminals located in the first zone exceeds a predetermined maximum value; and

changing a resource group mapped to the first zone in case that the number of terminals located in the first zone is less than a predetermined minimum value.

5. A method of a terminal, the method comprising:

receiving system information including information on resource groups;

transmitting, to a base station, a resource allocation request;

transmitting, to the base station, a control message including location information of a first zone where the terminal is located; and

receiving, from the base station, resource allocation information including at least one resource group, among the resource groups, allocated based on the location information,

wherein a number of the at least one resource group allocated to the terminal is determined based on a number of terminals in a connected state and a number of terminals in an idle state which are located in the first zone.

6. The method of claim 5,

wherein the transmitting comprises transmitting situation information associated with the terminal,

wherein the at least one resource group, which is different from a resource group allocated to a second zone adjacent to the first zone, among the resource groups is allocated based on the location information and the situation information, and

wherein the situation information includes at least one of information on a number of terminals located in the first zone or a size of the first zone.

7. The method of claim 6, wherein a reporting period of the location information is determined based on the situation information, and

wherein messages are transmitted on the at least one allocated resource group using a different transmission power according to a type of each of the messages.

8. The method of claim 5,

wherein the resource allocation information includes least two resource groups in case that a number of terminals located in the first zone exceeds a predetermined maximum value, and

wherein a resource group mapped to the first zone is changed case that the number of terminals located in the first zone is less than a predetermined minimum value.

9. A base station comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

transmit system information including information on resource groups,

receive, from a terminal, a resource allocation request,

receive, from the terminal, a control message including location information of a first zone where the terminal is located, and

allocate at least one resource group among the resource groups based on the location information,

wherein a number of the at least one resource group allocated to the terminal is determined based on a number of terminals in a connected state and a number of terminals in an idle state which are located in the first zone.

10. The base station of claim 9, wherein the controller is further configured to:

receive situation information associated with the terminal, and

allocate the at least one resource group, which is different from a resource group allocated to a second zone adjacent to the first zone, among the resource groups to the terminal based on the location information and the situation information,

wherein the situation information includes at least one of information on a number of terminals located in the first zone or a size of the first zone.

11. The base station of claim 10,

wherein a reception period of the location information is determined based on the situation information, and

wherein messages are transmitted on the at least one allocated resource group using a different transmission power according to a type of each of the messages.

12. The base station of claim 9, wherein the controller is further configured to:

allocate at least two resource groups, in case that a number of terminals located in the first zone exceeds a predetermined maximum value, and

change a resource group mapped to the first zone in case that the number of terminals located in the first zone is less than a predetermined minimum value.

13. A terminal comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

receive system information including information on resource groups,

transmit, to a base station, a resource allocation request,

transmit, to the base station, a control message including location information of a first zone where the terminal is located, and

receive, from the base station, resource allocation information including at least one resource group, among the resource groups, allocated based on the location information,

wherein a number of the at least one resource group allocated to the terminal is determined based on a number of terminals in a connected state and a number of terminals in an idle state which are located in the first zone.

14. The terminal of claim 13,

wherein the controller is further configured to control to transmit situation information associated with the terminal,

wherein the at least one resource group, which is different from a resource group allocated to a second zone adjacent to the first, zone among the resource groups is allocated based on the location information and the situation information, and

wherein the situation information includes at least one of information on a number of terminals located in the first zone or a size of the first zone.

15. The terminal of claim 14,

wherein a reporting period of the location information is determined based on the situation information, and

wherein messages are transmitted on the at least one allocated resource group using a different transmission power according to a type of each of the messages.

16. The terminal of claim 13,

wherein the resource allocation information includes at least two resource groups in case that a number of terminals located in the first zone exceeds a predetermined maximum value, and

wherein a resource group mapped to the first zone is changed in case that the number of terminals located in the first zone is less than a predetermined minimum value.
