Abstract

A Machine Type Communication (MTC) method for an MTC device to configure a plurality of MTC logical channels associated with an MTC application is provided The method comprises the steps of: configuring, in a Medium Access Control (MAC) layer, the MTC logical channels independently from a Common Control Channel (CCCH), a Dedicated Control Channel (DCCH), and a Dedicated Traffic Channel (DTCH), wherein the MTC logical channels include a Machine Type Communication Traffic Channel (MTCTCH) and a Machine Type Communication Control Channel (MTCCCH); carrying uplink and downlink traffic data dedicated for the MTC application executed by the MTC device in the MTCTCH; and carrying uplink and downlink control data dedicated for the MTC application executed by the MTC device in the MTCCCH.

Claims

1. A Machine Type Communication (MTC) method for an MTC device to configure a plurality of MTC logical channels associated with an MTC application, comprising:

configuring, in a Medium Access Control (MAC) layer, the MTC logical channels independently from a Common Control Channel (CCCH), a Dedicated Control Channel (DCCH), and a Dedicated Traffic Channel (DTCH), wherein the MTC logical channels include a Machine Type Communication Traffic Channel (MTCTCH) and a Machine Type Communication Control Channel (MTCCCH);

carrying uplink and downlink traffic data dedicated for the MTC application executed by the MTC device in the MTCTCH; and

carrying uplink and downlink control data dedicated for the MTC application executed by the MTC device in the MTCCCH.

2. The MTC method of claim 1, further comprising:

mapping the MTC logical channels to an Uplink Shared Channel (UL-SCH) in an uplink direction; and

mapping the MTC logical channels to a Downlink Shared Channel (DL-SCH) in a downlink direction, wherein the UL-SCH and the DL-SCH are a plurality of transport channels.

3. The MTC method of claim 1, wherein execution of the MTC application requires no human interaction.

4. The MTC method of claim 1, wherein the MTCTCH comprises a lower priority than the DTCH.

5. The MTC method of claim 1, wherein the MTCCCH comprises a lower priority than the CCCH and the DCCH.

6. The MTC method of claim 1, further comprising:

allocating a physical resource to the MTCTCH or the MTCCCH by using an allocation signal and an allocation method.

7. The MTC method of claim 6, wherein the allocation method comprises allocating the physical resource by using a dynamic allocation method.

8. The MTC method of claim 6 the allocation method comprises allocating the physical resource by using a pre-defined pattern allocation method.

9. The MTC method of claim 6, further comprising:

acquiring the allocation signal from a system information broadcast signal.

10. The MTC method of claim 6, further comprising:

acquiring the allocation signal from a Radio Resource Control (RRC) establishment message received when the MTC device accesses a network.

11. A Machine Type Communication (MTC) apparatus for configuring a plurality of MTC logical channels associated with an MTC application, comprising:

a processor configuring the MTC logical channels independently from a Common Control Channel (CCCH), a Dedicated Control Channel (DCCH), and a Dedicated Traffic Channel (DTCH) in a Medium Access Control (MAC) layer, wherein the MTC logical channels comprise a Machine Type Communication Traffic Channel (MTCTCH) and a Machine Type Communication Control Channel (MTCCCH), uplink and downlink traffic data dedicated for the MTC application is carried in the MTCCCH, and uplink and downlink control data dedicated for the MTC application is carried in the MTCCCH.

12. The MTC apparatus of claim 11, wherein the processor maps the MTC logical channels to an Uplink Shared Channel (UL-SCH) in an uplink direction, and maps the MTC logical channels to a Downlink Shared Channel (DL-SCH) in a downlink direction, wherein the UL-SCH and the DL-SCH are a plurality of transport channels.

13. The MTC apparatus of claim 11, wherein execution of the MTC application requires no human interaction.

14. The MTC apparatus of claim 11, wherein the MTCTCH comprises a lower priority than the DTCH.

15. The MTC apparatus of claim 11, wherein the MTCCCH comprises a lower priority than the CCCH and the DCCH.

16. The MTC apparatus of claim 11, wherein the processor further allocates a physical resource to the MTCTCH or the MTCCCH by using an allocation signal and an allocation method.

17. The MTC apparatus of claim 16, wherein the allocation method comprises allocating the physical resource by using a dynamic allocation method.

18. The MTC apparatus of claim 16, wherein the allocation method comprises allocating the physical resource by using a pre-defined pattern allocation method.

19. The MTC apparatus of claim 16, wherein the processor further acquires the allocation signal from a system information broadcast signal.

20. The MTC apparatus of claim 16, wherein the processor further acquires the allocation signal from a Radio Resource Control (RRC) establishment message received when the processor accesses a network.
