Abstract

A method and apparatus for transmitting and receiving persistent scheduling change information are disclosed. A machine-to-machine (M2M) device for receiving persistent scheduling change information in a wireless communication system includes a receiver for receiving, from a BS, a message comprising allocation period information including a persistent allocation period, wherein the message further comprises changed resource allocation information, when the allocation period information indicates temporal change or one time reallocation of uplink persistent allocation for the M2M device.

Claims

1. A method of transmitting persistent scheduling change information at a base station (BS) in a wireless communication system, the method comprising:

transmitting, to a machine-to-machine (M2M) device, a message comprising allocation period information including a persistent allocation period for the M2M device,

wherein the allocation period information indicates a temporary change or one-time reallocation when the allocation period information is set to a specific value, and

wherein the message further comprises changed resource allocation information when the allocation period information indicates the temporary change or one-time reallocation; and

receiving UL data from the M2M device through a resource indicated by the changed resource allocation information.

2. The method according to claim 1, wherein the set specific value is 0b1111.

3. The method according to claim 1, wherein the message is a UL M2M persistent allocation A-MAP IE (Information Element) message.

5. The method according to claim 1, further comprising:

receiving UL data through a persistent resource allocated before the message is received from the subsequent period, after the receiving of UL data from the M2M device through the resource indicated by the changed resource allocation information.

6. The method according to claim 1, wherein the resource indicated by the changed resource allocation information replaces a resource, which was previously persistently allocated for the same subframe as a subframe in which the message is transmitted, temporarily or one-time.

4. (canceled)

7. A method of receiving persistent scheduling change information at a machine-to-machine (M2M) device in a wireless communication system, the method comprising:

receiving a message comprising allocation period information including a persistent allocation period from a BS,

wherein the allocation period information indicates a temporary change or one-time reallocation when the allocation period information is set to a specific value, and

wherein the message further comprises changed resource allocation information when the allocation period information indicates the temporary change or one-time reallocation; and

transmitting UL data to the BS through a resource indicated by the changed resource allocation information.

8. The method according to claim 7, wherein the set specific value is 0b1111.

9. The method according to claim 7, wherein the message is a UL M2M persistent allocation A-MAP IE (Information Element) message.

11. The method according to claim 7, further comprising:

transmitting UL data through a persistent resource persistently allocated before receiving the message from the subsequent period, after the transmitting of UL data to the BS through the resource indicated by the changed resource allocation information.

12. The method according to claim 7, wherein the resource indicated by the changed resource allocation information replaces a resource, which was previously persistently allocated for the same subframe as a subframe in which the message is transmitted, temporarily or one-time.

10. (canceled)

13. A machine-to-machine (M2M) device for receiving persistent scheduling change information in a wireless communication system, the M2M device comprising:

a receiver configured to receive, from a BS, a message comprising allocation period information including a persistent allocation period,

wherein the allocation period information indicates a temporary change or one-time reallocation when the allocation period information is set to a specific value, and

wherein the message further comprises changed resource allocation information, when the allocation period information indicates a temporal change or one-time reallocation; and

a transmitter configured to transmit UL data to the BS through a resource indicated by the changed resource allocation information.

15. The M2M device according to claim 13, further comprising:

a processor configured to control the transmitter to transmit UL data through a persistent resource allocated before the message is received, after transmitting the UL data to the BS through the resource indicated by the changed resource allocation information,

wherein the transmitter is further configured to transmit UL data through the persistent resource allocated before the message is received, after transmitting the UL data to the BS.

14. (canceled)

16. A base station of transmitting persistent scheduling change information in a wireless communication system, the base station comprising:

a transmitter configured to transmit, to a machine-to-machine (M2M) device, a message comprising allocation period information including a persistent allocation period for the M2M device,

wherein the allocation period information indicates a temporary change or one-time reallocation when the allocation period information is set to a specific value, and

wherein the message further comprises changed resource allocation information when the allocation period information indicates the temporary change or one-time reallocation; and

a receiver configured to receive UL data from the M2M device through a resource indicated by the changed resource allocation information.

17. The base station according to claim 16, wherein the receiver is further configured to receive UL data through a persistent resource allocated before the message is received from the subsequent period, after the receiving of UL data from the M2M device through the resource indicated by the changed resource allocation information.

18. The base station according to claim 16, wherein the resource indicated by the changed resource allocation information replaces a resource, which was previously persistently allocated for the same subframe as a subframe in which the message is transmitted, temporarily or one-time.

19. The base station according to claim 16, wherein the set specific value is 0b1111.
