METHOD OF TRANSMITTING DATA IN MACHINE TYPE COMMUNICATION DEVICE AND MOBILE COMMUNICATION SYSTEM USING THE SAME
First Claim
1. A method of transmitting data in at least one machine type communication (MTC) device belonging to an MTC group, the MTC group being identified by a unique identity according to application features, the method comprising:
- setting, by each MTC device, unique transmission latency;
waiting for the set transmission latency and receiving information on uplink resources allocated to each MTC group identity from a base station; and
transmitting uplink data using the allocated uplink resources.

Abstract
Provided is a method of transmitting data in at least one machine type communication (MTC) device belonging to an MTC group identified by a unique identity according to application features. The method includes setting, by at least one MTC device belonging to the MTC group, unique transmission latency; waiting, by the MTC device, for the set transmission latency and then receiving information on uplink resources allocated to each MTC group identity from a base station; and transmitting, by the MTC device, uplink data using the allocated uplink resources.

8. A mobile communication system for providing machine type communication (MTC) service, the mobile communication system comprising:
-
a base station configured to assign a unique identity to each of MTC groups classified according to application features, allocate uplink resources to each MTC group identity, and transmits information on the uplink resources allocated to each MTC group identity; and at least one MTC device belonging to one MTC group, the MTC device being configured to set a unique transmission latency, wait for the set latency, receive information on the uplink resources allocated to each MTC group identity from the base station, and transmit data to the base station using the allocated uplink resources. - View Dependent Claims (9, 10, 11)

- 12. A base station communicating with at least one machine type communication (MTC) device, wherein the base station assigns a unique identity to each of MTC groups classified according to application features, allocates uplink resources to each MTC group identity, and transmits information on the uplink resources allocated to each MTC group identity via a physical downlink control channel (PDCCH).

15. A machine type communication (MTC) device communicating with a base station in a mobile communication network providing an MTC service, wherein:
-
the MTC device sets a transmission latency, waits for the set latency, receives information on uplink resources allocated to each MTC group identity from a base station, and transmits uplink data using the allocated uplink resources, and the transmission latency uniquely set for at least one MTC device belonging to the same MTC group is selected with a random variable for each MTC device or with an offset differently set from at least another MTC device belonging to the same MTC group. - View Dependent Claims (16)
