1. A communication method according to an automatic repeat request scheme in a mobile communication system, the method comprising:
- transmitting a first retransmission packet periodically per a time period in response to a first negative acknowledgement (NACK) from a first user equipment for a first packet transmitted within a frame group comprising a plurality of successive frames; and
transmitting a second retransmission packet non-periodically in response to a second NACK from a second user equipment for a second packet transmitted within the frame group.

Abstract
A communication method according to an automatic repeat request scheme in a mobile communication system includes transmitting a retransmission packet per certain time period (periodically) in response to NACK of a first user equipment related to a first packet transmitted within a frame group consisting of a plurality of successive frames, and transmitting a retransmission packet non-periodically in response to NACK of a second user equipment related to a second packet transmitted within the frame group.

13. A communication method according to an automatic repeat request scheme in a mobile communication system, the method comprising:
-
transmitting a first negative acknowledgement (NACK) to a base station in response to a first packet received within a frame group including a plurality of successive frames; transmitting a second NACK to the base station in response to a second packet received within the frame group; receiving a first retransmission packet which is periodically retransmitted for the first packet after a lapse of a certain time period; receiving control information for a second retransmission packet for the second packet; and receiving the second retransmission packet which is non-periodically retransmitted for the second packet by using the control information. - View Dependent Claims (14, 15)

16. A communication method according to an automatic repeat request scheme in a mobile communication system, the method comprising:
-
transmitting a packet to a receiving side; receiving a first negative acknowledgement (NACK) from the receiving side in response to the packet; and transmitting a retransmission packet to the receiving side in response to the first NACK, the retransmission packet transmitted periodically per certain time period for at least one frame within a frame group including a plurality of successive frames; receiving a second NACK from the receiving side; and transmitting a retransmission packet non-periodically in response to the second NACK for at least one other frame within the frame group.
