1. A method of controlling uplink packet data transmission in a mobile communication system, comprising the steps of:
- acquiring transport format combination indicators (TFCIs) representing combinations of transport formats (TFs) of transport channels used for downlink packet data and TFs of a virtual transport channel used for controlling uplink packet data transmission;
determining a downlink signal destined for a user equipment (UE), for controlling the uplink packet data transmission;
selecting a TFCI corresponding to the downlink signal among the acquired TFCIs; and
transmitting the selected TFCI to the UE.

Abstract
A method and apparatus for transmitting scheduling grant information by a TFCI in Node B controlled scheduling of uplink packet transmission. In one embodiment, a scheduling command resulting from Node B controlled scheduling is mapped onto a TFCI and transmitted on the downlink. In another embodiment, an ACK/NACK signal determining retransmission of uplink packet data is mapped onto a TFCI and transmitted on the downlink.
