Patent ID: 7561550

Claim:
A scheduling method for a user equipment (UE) during soft handover in a mobile communication system supporting an enhanced uplink packet data service, the method comprising the steps of: receiving dedicated scheduling assignment information for dedicated scheduling assignment from a serving Node B by a UE that communicates with the serving Node B and at least one non-serving Node B due to soft handover; receiving, by the UE, at least one scheduling grant indicator for common scheduling assignment from the at least one non-serving Node B; determining a combined scheduling grant indicator by combining at least one scheduling grant indicator received from the at least one non-serving Node B; determining whether to use the combined scheduling grant indicator according to a predetermined reference; determining a maximum rate of an uplink according to the dedicated scheduling assignment information or the combined scheduling grant indicator; wherein each of the at least one scheduling grant indicator indicates whether the scheduling grant indicator is care signal by the UE or not, and wherein the at least one scheduling grant indicator represents a Down signal for indicating a command to decrease a maximum rate for the enhanced unlink packet data service by one step. or represents a Don't Care signal for indicating a command to follow the dedicated scheduling assignment information.
