1. A method of handling random access for a user equipment of a wireless communication system, the method comprising:
- transmitting a plurality of repetitions of a random access preamble in a plurality of subframes to a network of the wireless communication system, wherein each of the plurality of repetitions is transmitted in a separate subframe of the plurality of subframes and not overlapped; and
monitoring a physical downlink control channel in a plurality of random access response windows for receiving a random access response identified by a random access radio network temporary identifier (RA-RNTI) from the network, wherein each of the plurality of random access response windows is corresponding to one of the plurality of repetitions of the random access preamble;
wherein at least two of the plurality of random access response windows overlap.

Abstract
A method of handling random access for a user equipment of a wireless communication system includes transmitting a plurality of repetitions of a random access preamble to a network of the wireless communication system; and monitoring a physical downlink control channel (PDCCH) in a plurality of random access response windows for receiving a random access response identified by a random access radio network temporary identifier (RA-RNTI) from the network, wherein each of the plurality of random access response windows is corresponding to one of the plurality of repetitions of the random access preamble.

5. A method of handling random access for a user equipment of a wireless communication system, the method comprising:
-
transmitting a plurality of repetitions of a random access preamble in a plurality of subframes to a network of the wireless communication system; and monitoring a physical downlink control channel in a random access response window which starts at a first subframe containing the end of the first repetition of the random access preamble plus M subframes and ends at a second subframe containing the end of the last repetition of the random access preamble plus (N+W) subframes, for receiving a random access response identified by a random access radio network temporary identifier (RA-RNTI) from the network. - View Dependent Claims (6, 7)

8. A method of handling random access for a user equipment of a wireless communication system, the method comprising:
-
transmitting a plurality of repetitions of a random access preamble in a plurality of subframes to a network of the wireless communication system; and monitoring a physical downlink control channel in a random access response window which starts at a subframe containing the end of the first repetition of the random access preamble plus N subframes and has a length X subframes, for receiving a random access response identified by a random access radio network temporary identifier (RA-RNTI) from the network; wherein the value of X allows the user equipment to receive the random access response corresponding to the last repetition of the plurality of repetitions of the random access preamble. - View Dependent Claims (9, 10)
