Method and apparatus for transmitting and receiving downlink control information in a mobile communication system supporting uplink packet data service

摘要

A method and apparatus for transmitting and receiving downlink control information in a mobile communication system supporting an uplink packet data service are provided. To transmit packet data in an HARQ mobile communication system, a second transceiver receives an RG as rate control information from a first transceiver. The second transceiver sets the allowed maximum data rate of an HARQ process to which the RG is applied to the allowed maximum data rate of an HARQ process previous to the HARQ process, if the RG indicates hold. The second transceiver transmits packet data within the set allowed maximum data rate to the first transceiver.

主权项

1. A method of transmitting uplink packet data by an user equipment (UE) including a plurality of hybrid automatic repeat request (HARQ) processes in a mobile communication system, comprising:
detecting a relative grant (RG) associated with a first HARQ process from a node B by the UE; setting an allowed maximum power ratio of a first transmission time interval (TTI) of the first HARQ process to an allowed maximum power ratio in a immediately previous TTI of the first TTI, if the RG indicates hold; and transmitting packet data of the first HARQ process based on the allowed maximum power ratio of the first HARQ process in the first TTI to the node B by the UE.
