Abstract

A method and a system of multiplexing Machine Type Communication (MTC) data of MTC devices over a single radio block period are provided. The method includes providing, by a base station, resource information to a plurality of MTC devices, where the resource information includes a time slot allocated to the plurality of MTC devices in each frame of a radio block period, a temporary flow identifier, and the sub-block index information. The method further includes packing MTC data associated with each of the plurality of MTC devices in a data packet. Furthermore, the method includes multiplexing the data packet including the MTC data associated with the plurality of MTC devices in downlink over the time slot allocated in each frame of the radio block period.

Claims

1. A method of multiplexing machine type communication (MTC) data of multiple MTC devices in a wireless network environment, the method comprising:

providing, by a base station, resource information to a plurality of MTC devices, wherein the resource information includes a time slot allocated to each of the plurality of MTC devices in each frame of a radio block period, a temporary flow identifier (TFI), and sub-block index information;

packing MTC data associated with each of the plurality of MTC devices in a data packet; and

multiplexing the data packet including the MTC data associated with each of the plurality of MTC devices in downlink over the time slot allocated in each frame of the radio block period,

wherein the data packet comprises multiple sub-blocks and a common header which is common to the multiple sub-blocks,

wherein each of the multiple sub-blocks is associated with one of the plurality of MTC devices,

wherein the common header includes a first group TFI for the plurality of the MTC devices,

wherein a sub-block of the multiple sub-blocks comprises an MTC device specific header including a first user specific TFI for a MTC device which is associated with the sub-block, and

wherein the MTC device specific header further includes a field indicating a TFI increment value.

2. The method of claim 1, wherein each of the multiple sub-blocks comprises an MTC device specific data unit.

3. The method of claim 2, wherein the packing of the MTC data associated with each of the plurality of MTC devices in the data packet comprises:

packing MTC data associated with each of the plurality of MTC devices in an MTC specific data unit of at least one of the multiple sub-blocks; and

encoding a sub-block index number of the at least one of the multiple sub-blocks in the MTC device specific header.

4. The method of claim 3, wherein the sub-block index number indicates presence of the MTC data associated with one of the plurality of MTC devices in the at least one of the multiple sub-blocks.

5. The method of claim 4, wherein the sub-block index information is indicative of a sub-index number of the at least one of the multiple sub-blocks which contains the MTC data associated with one of the plurality of MTC devices.

6. The method of claim 5, wherein the TFI comprises a second user specific TFI assigned to each of the plurality of MTC devices and a second group TFI assigned to the plurality of MTC devices.

7. An apparatus comprising:

at least one processor; and

a memory coupled to the at least one processor,

wherein the memory includes a machine type communication (MTC) data multiplexer configured for;

providing resource information to a plurality of MTC devices, wherein the resource information includes a time slot allocated to each of the plurality of MTC devices in each frame of a radio block period, a temporary flow identifier (TFI), and sub-block index information,

packing MTC data associated with each of the plurality of MTC devices in a data packet, and

multiplexing the data packet including the MTC data associated with each of the plurality of MTC devices in downlink over the time slot allocated in each frame of the radio block period,

wherein the data packet comprises multiple sub-blocks and a common header which is common to the multiple sub-blocks,

wherein each of the multiple sub-blocks is associated with one of the plurality of MTC devices,

wherein the common header includes a first group TFI for the plurality of the MTC devices,

wherein a sub-block of the multiple sub-blocks comprises an MTC device specific header including a first user specific TFI for a MTC device which is associated with the sub-block, and

wherein the MTC device specific header further includes a field indicating a TFI increment value.

8. The apparatus of claim 7, wherein each of the multiple sub-blocks comprises an MTC device specific data unit.

9. The apparatus of claim 8, wherein the MTC data multiplexer is configured for:

packing MTC data associated with each of the plurality of MTC devices in an MTC specific data unit of at least one of the multiple sub-blocks; and

encoding a sub-block index number of the at least one of the multiple sub-blocks in the MTC device specific header.

10. The apparatus of claim 9, wherein the sub-block index number indicates presence of the MTC data associated with one of the plurality of MTC devices in the at least one of the multiple sub-blocks.

11. The apparatus of claim 10, wherein the sub-block index information is indicative of a sub-index number of the at least one of the multiple sub-blocks which contains the MTC data associated with one of the plurality of MTC devices.

12. The apparatus of claim 11, wherein the TFI comprises a second user specific TFI assigned to each of the plurality of MTC devices and a second group TFI assigned to the plurality of MTC devices.
