METHOD FOR MACHINE TYPE COMMUNICATION USER EQUIPMENT TO CONNECT TO EVOLVED NODE-B AND APPARATUS EMPLOYING THE SAME
First Claim
1. A method for machine type communication (MTC) user equipment (UE) to connect to an evolved Node-B (eNB), comprising:
- receiving, at the MTC UE, system information or a handover command from the eNB;
transmitting, at the MTC UE, a random access preamble to the eNB;
receiving, at the MTC UE, a random access response message from the eNB; and
transmitting, at the MTC UE, a connection request message or a handover confirm message including information about a dedicated bandwidth of the MTC UE to the eNB such that the MTC UE is allocated the dedicated bandwidth.

Abstract
Provided are a method for machine type communication (MTC) user equipment (UE) to connect to an evolved Node-B (eNB) in a random access procedure, and an apparatus employing the method. The method for MTC UE to connect to an eNB includes receiving, at the MTC UE, system information or a handover command from the eNB, transmitting, at the MTC UE, a random access preamble to the eNB, receiving, at the MTC UE, a random access response message from the eNB, and transmitting, at the MTC UE, a connection request message or a handover confirm message including information about a dedicated bandwidth of the MTC UE to the eNB such that the MTC UE can be allocated the dedicated bandwidth. Using this method, an eNB is notified of a dedicated bandwidth of MTC UE, and thus can effectively utilize radio resources.

12. Machine type communication (MTC) user equipment (UE) which connects with an evolved Node-B (eNB), comprising:
-
a receiver configured to receive system information or a handover command from the eNB; a transmitter configured to transmit a random access preamble to the eNB; and a controller configured to control the receiver and the transmitter, wherein the receiver receives a random access response message from the eNB, and the transmitter transmits a connection request message or a handover confirm message including information about a dedicated bandwidth of the MTC UE to the eNB such that the MTC UE is allocated a frequency band corresponding to the dedicated bandwidth of the MTC UE. - View Dependent Claims (13, 14, 15)
