## Abstract

A method of transmitting packet in a mobile station is provided. The method includes determining whether a resource reserved for a special purpose is overlapped with a resource for transmitting a packet by the mobile station, on the basis of resource allocation information on the mobile station, and delaying the transmission of the packet if the reserved resource is overlapped with the resource for transmitting the packet. Accordingly, it is possible to increase uplink packet transmission efficiency without increasing downlink overhead, by avoiding or adjusting collision of an uplink packet transmission with a time-frequency resource reserved for another purpose.

## Claims

### Claim 1

A method of performing uplink transmission at a user equipment (UE), the method comprising:
determining whether a hybrid automatic repeat request (HARQ) retransmission collides with a transmission for a random access channel (RACH) in a subframe; and
performing the HARQ retransmission if the HARQ retransmission does not collide with the transmission for the RACH in the subframe,
wherein a current value of information indicating a redundancy version (RV) for the HARQ retransmission is incremented by 1 if the HARQ retransmission does not collide with the transmission for the RACH in the subframe.

### Claim 2

A user equipment (UE) for performing uplink transmission, the UE comprising:
a processor; and a memory communicating with the processor, wherein the processor is configured to:
determine whether a hybrid automatic repeat request (HARQ) retransmission collides with a transmission for a random access channel (RACH) in a subframe, and
perform the HARQ retransmission if the HARQ retransmission does not collide with the transmission for the RACH in the subframe,
wherein a current value of information indicating a redundancy version (RV) for the HARQ retransmission is incremented by 1 if the HARQ retransmission does not collide with the transmission for the RACH in the subframe.
