Abstract

A method of receiving packets at a network in a mobile communication system. Including receiving a first packet from a user equipment; and receiving a second packet from the user equipment regardless of a reception status for the first packet, if control information for the second packet is transmitted to the user equipment.

Claims

1. A method of receiving packets at a network in a mobile communication system, the method comprising:

receiving a first packet from a user equipment; and

receiving a second packet from the user equipment regardless of a reception status for the first packet, if control information for the second packet is transmitted to the user equipment,

wherein the user equipment transmits the second packet to the network on an assumption that the first packet is successfully received by the network.

2. The method of claim 1, wherein the control information comprises an uplink scheduling grant message allocating uplink resources for the second packet.

3. The method of claim 1, wherein the second packet is not a retransmission packet.

4. The method of claim 1, further comprising:

transmitting a reception status signal for the first packet to the user equipment.

5. The method of claim 1, wherein the mobile communication system is based on an orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) scheme.

6. A network for transmitting packets in a mobile communication system, wherein the network is configured to perform operations of:

receiving a first packet from a user equipment; and

receiving a second packet from the user equipment regardless of a reception status for the first packet, if control information for the second packet is transmitted to the user equipment,

wherein the user equipment transmits the second packet to the network on an assumption that the first packet is successfully received by the network.

7. The network of claim 6, wherein the control information comprises an uplink scheduling grant message allocating uplink resources for the second packet.

8. The network of claim 6, wherein the second packet is not a retransmission packet.

9. The network of claim 6, wherein the network is further configured to perform an operation of:

transmitting a reception status signal for the first packet to the user equipment.

10. The network of claim 6, wherein the mobile communication system is based on an orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) scheme.
