Abstract

A resource allocation method and apparatus are provided for allocating resources for handover between sectors of a cell with handover latency. A resource allocation method of a base station in a wireless communication system includes receiving a handover request message from a terminal for handover from a first sector to a second sector within a cell and transmitting an allocation message for allocating a Mobile Allocation Index Offset (MAIO) to the terminal, the MAIO being identical to an MAIO used in the first sector. The resource allocation method and apparatus are advantageous in preventing a voice break occurring due to handover latency caused by signaling between the base station and the terminal in inter-sector handover.

Claims

1. A resource allocation method of a base station in a wireless communication system, the method comprising:

receiving a handover request message from a terminal for handover from a first sector to a second sector within a cell; and

transmitting an allocation message for allocating a Mobile Allocation Index Offset (MAIO) to the terminal, the MAIO being identical to an MAIO used in the first sector.

2. The method of claim 1, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

3. A resource allocation method of a base station in a wireless communication system, the method comprising:

receiving an initial access request message from a terminal through one sector of a cell; and

transmitting an allocation message for allocating a Mobile Allocation Index Offset (MAIO) to the terminal, the MAIO being identical to an MAIO used in another sector of the cell.

4. The method of claim 3, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

5. A resource allocation method for a terminal in a wireless communication system, the method comprising:

transmitting, at the terminal, a handover request message to a base station for handover from a first sector to a second sector within a cell; and

receiving an allocation message for allocating a Mobile Allocation Index Offset (MAIO) from the base station, the MAIO being identical to an MAIO used in the first sector.

6. The method of claim 5, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

7. A resource allocation method for a terminal in a wireless communication system, the method comprising:

transmitting, at the terminal, an initial access request message to a base station through one sector of a cell; and

receiving an allocation message for allocating a Mobile Allocation Index Offset (MAIO) from the base station, the MAIO being identical to an MAIO used in another sector of the cell.

8. The method of claim 7, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

9. A base station for allocating resources in a wireless communication system, the base station comprising:

a transceiver which transmits and receives data to and from a terminal; and

a controller which controls receiving a handover request message from a terminal for handover from a first sector to a second sector within a cell and transmitting an allocation message for allocating a Mobile Allocation Index Offset (MAIO) to the terminal, the MAIO being identical to an MAIO used in the first sector.

10. The base station of claim 9, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

11. A base station for allocating resources in a wireless communication system, the base station comprising:

a transceiver which transmits and receives data to and from a terminal; and

a controller which controls receiving an initial access request message from a terminal through one sector of a cell and transmitting an allocation message for allocating a Mobile Allocation Index Offset (MAIO) to the terminal, the MAIO being identical to an MAIO used in another sector of the cell.

12. The base station of claim 11, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

13. A terminal being allocated resources in a wireless communication system, the terminal comprising:

a transceiver which transmits and receives data to and from a base station; and

a controller which controls transmitting, at the terminal, a handover request message to a base station for handover from a first sector to a second sector within a cell and receiving an allocation message for allocating a Mobile Allocation Index Offset (MAIO) from the base station, the MAIO being identical to an MAIO used in the first sector.

14. The terminal of claim 13, wherein the allocation message is a message for allocating at least one time slot that is not used in other sectors of the cell with priority.

15. A terminal being allocated resources in a wireless communication system, the terminal comprising:

a transceiver which transmits and receives data to and from a base station; and

a controller which controls transmitting, at the terminal, an initial access request message to a base station through one sector of a cell and receiving an allocation message for allocating a Mobile Allocation Index Offset (MAIO) from the base station, the MAIO being identical to an MAIO used in another sector of the cell.

16. The terminal of claim 15, wherein the allocation message is a message for allocating at least one time that is not used in other sectors of the cell with priority.
