1. A method for improving a coverage of an uplink Voice over IP (VoIP) transmission of a wireless device, the method comprising:
assigning a first hybrid automatic repeat request (HARQ) process to a first VoIP packet for an initial transmission of the wireless device;
assigning a second HARQ process to a second VoIP packet for the initial transmission of the wireless device; and
transmitting the first and second VoIP packets from the wireless device to a base station;
wherein a sum of transmission times of the first VoIP packet and the second VoIP packet is the same as a round trip time for retransmission for the HARQ process.
